entirety.", "BACKGROUND 1.Field The present disclosure relates generally to data networking and in particular to a backhaul radio for connecting remote edge access networks to core networks.", "2.Related Art Data networking traffic has grown at approximately 100% per year for over 20 years and continues to grow at this pace.", "Only transport over optical fiber has shown the ability to keep pace with this ever-increasing data networking demand for core data networks.", "While deployment of optical fiber to an edge of the core data network would be advantageous from a network performance perspective, it is often impractical to connect all high bandwidth data networking points with optical fiber at all times.", "Instead, connections to remote edge access networks from core networks are often achieved with wireless radio, wireless infrared, and/or copper wireline technologies.", "Radio, especially in the form of cellular or wireless local area network (WLAN) technologies, is particularly advantageous for supporting mobility of data networking devices.", "However, cellular base stations or WLAN access points inevitably become very high data bandwidth demand points that require continuous connectivity to an optical fiber core network.", "When data aggregation points, such as cellular base station sites, WLAN access points, or other local area network (LAN) gateways, cannot be directly connected to a core optical fiber network, then an alternative connection, using, for example, wireless radio or copper wireline technologies, must be used.", "Such connections are commonly referred to as “backhaul.” Many cellular base stations deployed to date have used copper wireline backhaul technologies such as T1, E1, DSL, etc.", "when optical fiber is not available at a given site.", "However, the recent generations of HSPA+ and LTE cellular base stations have backhaul requirements of 100 Mb/s or more, especially when multiple sectors and/or multiple mobile network operators per cell site are considered.", "WLAN access points commonly have similar data backhaul requirements.", "These backhaul requirements cannot be practically satisfied at ranges of 300 m or more by existing copper wireline technologies.", "Even if LAN technologies such as Ethernet over multiple dedicated twisted pair wiring or hybrid fiber/coax technologies such as cable modems are considered, it is impractical to backhaul at such data rates at these ranges (or at least without adding intermediate repeater equipment).", "Moreover, to the extent that such special wiring (i.e., CAT 5/6 or coax) is not presently available at a remote edge access network location; a new high capacity optical fiber is advantageously installed instead of a new copper connection.", "Rather than incur the large initial expense and time delay associated with bringing optical fiber to every new location, it has been common to backhaul cell sites, WLAN hotspots, or LAN gateways from offices, campuses, etc.", "using microwave radios.", "An exemplary backhaul connection using the microwave radios 132 is shown in FIG.", "1.Traditionally, such microwave radios 132 for backhaul have been mounted on high towers 112 (or high rooftops of multi-story buildings) as shown in FIG.", "1, such that each microwave radio 132 has an unobstructed line of sight (LOS) 136 to the other.", "These microwave radios 132 can have data rates of 100 Mb/s or higher at unobstructed LOS ranges of 300 m or longer with latencies of 5 ms or less (to minimize overall network latency).", "Traditional microwave backhaul radios 132 operate in a Point-to-point (PTP) configuration using a single “high gain” (typically >30 dBi or even >40 dBi) antenna at each end of the link 136, such as, for example, antennas constructed using a parabolic dish.", "Such high gain antennas mitigate the effects of unwanted multipath self-interference or unwanted co-channel interference from other radio systems such that high data rates, long range and low latency can be achieved.", "These high gain antennas however have narrow radiation patterns.", "Furthermore, high gain antennas in traditional microwave backhaul radios 132 require very precise, and usually manual, physical alignment of their narrow radiation patterns in order to achieve such high performance results.", "Such alignment is almost impossible to maintain over extended periods of time unless the two radios have a clear unobstructed line of sight (LOS) between them over the entire range of separation.", "Furthermore, such precise alignment makes it impractical for any one such microwave backhaul radio to communicate effectively with multiple other radios simultaneously (i.e., a “point-to-multipoint” (PMP) configuration).", "In wireless edge access applications, such as cellular or WLAN, advanced protocols, modulation, encoding and spatial processing across multiple radio antennas have enabled increased data rates and ranges for numerous simultaneous users compared to analogous systems deployed 5 or 10 years ago for obstructed LOS propagation environments where multipath and co-channel interference were present.", "In such systems, “low gain” (usually <6 dBi) antennas are generally used at one or both ends of the radio link both to advantageously exploit multipath signals in the obstructed LOS environment and allow operation in different physical orientations as would be encountered with mobile devices.", "Although impressive performance results have been achieved for edge access, such results are generally inadequate for emerging backhaul requirements of data rates of 100 Mb/s or higher, ranges of 300 m or longer in obstructed LOS conditions, and latencies of 5 ms or less.", "In particular, “street level” deployment of cellular base stations, WLAN access points or LAN gateways (e.g., deployment at street lamps, traffic lights, sides or rooftops of single or low-multiple story buildings) suffers from problems because there are significant obstructions for LOS in urban environments (e.g., tall buildings, or any environments where tall trees or uneven topography are present).", "FIG.", "1 illustrates edge access using conventional unobstructed LOS PTP microwave radios 132.The scenario depicted in FIG.", "1 is common for many 2nd Generation (2G) and 3rd Generation (3G) cellular network deployments using “macrocells”.", "In FIG.", "1, a Cellular Base Transceiver Station (BTS) 104 is shown housed within a small building 108 adjacent to a large tower 112.The cellular antennas 116 that communicate with various cellular subscriber devices 120 are mounted on the towers 112.The PTP microwave radios 132 are mounted on the towers 112 and are connected to the BTSs 104 via an nT1 interface.", "As shown in FIG.", "1 by line 136, the radios 132 require unobstructed LOS.", "The BTS on the right 104a has either an nT1 copper interface or an optical fiber interface 124 to connect the BTS 104a to the Base Station Controller (BSC) 128.The BSC 128 either is part of or communicates with the core network of the cellular network operator.", "The BTS on the left 104b is identical to the BTS on the right 104a in FIG.", "1 except that the BTS on the left 104b has no local wireline nT1 (or optical fiber equivalent) so the nT1 interface is instead connected to a conventional PTP microwave radio 132 with unobstructed LOS to the tower on the right 112a.", "The nT1 interfaces for both BTSs 104a, 104b can then be backhauled to the BSC 128 as shown in FIG.", "1.FIG.", "2A is a block diagram of the major subsystems of a conventional PTP microwave radio 200A for the case of Time-Division Duplex (TDD) operation, and FIG.", "2B is a block diagram of the major subsystems of a conventional PTP microwave radio 200B for the case of Frequency-Division Duplex (FDD) operation.", "As shown in FIG.", "2A and FIG.", "2B, the conventional PTP microwave radio traditionally uses one or more (i.e.", "up to “n”) T1 interfaces 204A and 204B (or in Europe, E1 interfaces).", "These interfaces (204A and 204B) are common in remote access systems such as 2G cellular base stations or enterprise voice and/or data switches or edge routers.", "The T1 interfaces are typically multiplexed and buffered in a bridge (e.g., the Interface Bridge 208A, 208B) that interfaces with a Media Access Controller (MAC) 212A, 212B.", "The MAC 212A, 212B is generally denoted as such in reference to a sub-layer of Layer 2 within the Open Systems Interconnect (OSI) reference model.", "Major functions performed by the MAC include the framing, scheduling, prioritizing (or “classifying”), encrypting and error checking of data sent from one such radio at FIG.", "2A or FIG.", "2B to another such radio.", "The data sent from one radio to another is generally in a “user plane” if it originates at the T1 interface(s) or in the “control plane” if it originates internally such as from the Radio Link Controller (RLC) 248A, 248B shown in FIG.", "2A or FIG.", "2B.", "With reference to FIGS.", "2A and 2B, the Modem 216A, 216B typically resides within the “baseband” portion of the Physical (PHY) layer 1 of the OSI reference model.", "In conventional PTP radios, the baseband PHY, depicted by Modem 216A, 216B, typically implements scrambling, forward error correction encoding, and modulation mapping for a single RF carrier in the transmit path.", "In receive, the modem typically performs the inverse operations of demodulation mapping, decoding and descrambling.", "The modulation mapping is conventionally Quadrature Amplitude Modulation (QAM) implemented with In-phase (I) and Quadrature-phase (Q) branches.", "The Radio Frequency (RF) 220A, 220B also resides within the PHY layer of the radio.", "In conventional PTP radios, the RF 220A, 220B typically includes a single transmit chain (Tx) 224A, 224B that includes I and Q digital to analog converters (DACs), a vector modulator, optional upconverters, a programmable gain amplifier, one or more channel filters, and one or more combinations of a local oscillator (LO) and a frequency synthesizer.", "Similarly, the RF 220A, 220B also typically includes a single receive chain (Rx) 228A, 228B that includes I and Q analog to digital converters (ADCs), one or more combinations of an LO and a frequency synthesizer, one or more channel filters, optional downconverters, a vector demodulator and an automatic gain control (AGC) amplifier.", "Note that in many cases some of the one or more LO and frequency synthesizer combinations can be shared between the Tx and Rx chains.", "As shown in FIGS.", "2A and 2B, conventional PTP radios 200A, 200B also include a single power amplifier (PA) 232A, 232B.", "The PA 232A, 232B boosts the transmit signal to a level appropriate for radiation from the antenna in keeping with relevant regulatory restrictions and instantaneous link conditions.", "Similarly, such conventional PTP radios 232A, 232B typically also include a single low-noise amplifier (LNA) 236, 336 as shown in FIGS.", "2A and 2B.", "The LNA 236A, 236B boosts the received signal at the antenna while minimizing the effects of noise generated within the entire signal path.", "As described above, FIG.", "2A illustrates a conventional PTP radio 200A for the case of TDD operation.", "As shown in FIG.", "2A, conventional PTP radios 200A typically connect the antenna 240A to the PA 232A and LNA 236A via a band-select filter 244A and a single-pole, single-throw (SPST) switch 242A.", "As described above, FIG.", "2B illustrates a conventional PTP radio 200B for the case of FDD operation.", "As shown in FIG.", "2B, in conventional PTP radios 200B, then antenna 240B is typically connected to the PA 232B and LNA 236B via a duplexer filter 244B.", "The duplexer filter 244B is essentially two band-select filters (tuned respectively to the Tx and Rx bands) connected at a common point.", "In the conventional PTP radios shown in FIGS.", "2A and 2B, the antenna 240A, 240B is typically of very high gain such as can be achieved by a parabolic dish so that gains of typically >30 dBi (or even sometimes >40 dBi), can be realized.", "Such an antenna usually has a narrow radiation pattern in both the elevation and azimuth directions.", "The use of such a highly directive antenna in a conventional PTP radio link with unobstructed LOS propagation conditions ensures that the modem 216A, 216B has insignificant impairments at the receiver (antenna 240A, 240B) due to multipath self-interference and further substantially reduces the likelihood of unwanted co-channel interference due to other nearby radio links.", "Although not explicitly shown in FIGS.", "2A and 2B, the conventional PTP radio may use a single antenna structure with dual antenna feeds arranged such that the two electromagnetic radiation patterns emanated by such an antenna are nominally orthogonal to each other.", "An example of this arrangement is a parabolic dish.", "Such an arrangement is usually called dual-polarized and can be achieved either by orthogonal vertical and horizontal polarizations or orthogonal left-hand circular and right-hand circular polarizations.", "When duplicate modem blocks, RF blocks, and PA/LNA/switch blocks are provided in a conventional PTP radio, then connecting each PHY chain to a respective polarization feed of the antenna allows theoretically up to twice the total amount of information to be communicated within a given channel bandwidth to the extent that cross-polarization self-interference can be minimized or cancelled sufficiently.", "Such a system is said to employ “dual-polarization” signaling.", "Such systems may be referred to as having two “streams” of information, whereas multiple input multiple output (MIMO) systems utilizing spatial multiplexing may achieve successful communications using even more than two streams in practice.", "When an additional circuit (not shown) is added to FIG.", "2A that can provide either the RF Tx signal or its anti-phase equivalent to either one or both of the two polarization feeds of such an antenna, then “cross-polarization” signaling can be used to effectively expand the constellation of the modem within any given symbol rate or channel bandwidth.", "With two polarizations and the choice of RF signal or its anti-phase, then an additional two information bits per symbol can be communicated across the link.", "Theoretically, this can be extended and expanded to additional phases, representing additional information bits.", "At the receiver, for example, a circuit (not shown) could detect if the two received polarizations are anti-phase with respect to each other, or not, and then combine appropriately such that the demodulator in the modem block can determine the absolute phase and hence deduce the values of the two additional information bits.", "Cross-polarization signaling has the advantage over dual-polarization signaling in that it is generally less sensitive to cross-polarization self-interference but for high order constellations such as 64-QAM or 256-QAM, the relative increase in channel efficiency is smaller.", "In the conventional PTP radios shown in FIGS.", "2A and 2B, substantially all the components are in use at all times when the radio link is operative.", "However, many of these components have programmable parameters that can be controlled dynamically during link operation to optimize throughout and reliability for a given set of potentially changing operating conditions.", "The conventional PTP radios of FIGS.", "2A and 2B control these link parameters via a Radio Link Controller (RLC) 248A, 248B.", "The RLC functionality is also often described as a Link Adaptation Layer that is typically implemented as a software routine executed on a microcontroller within the radio that can access the MAC 212A, 212B, Modem 216A, 216B, RF 220A, 220B and/or possibly other components with controllable parameters.", "The RLC 248A, 248B typically can both vary parameters locally within its radio and communicate with a peer RLC at the other end of the conventional PTP radio link via “control frames” sent by the MAC 212A, 212B with an appropriate identifying field within a MAC Header.", "Typical parameters controllable by the RLC 248A, 248B for the Modem 216A, 216B of a conventional PTP radio include encoder type, encoding rate, constellation selection and reference symbol scheduling and proportion of any given PHY Protocol Data Unit (PPDU).", "Typical parameters controllable by the RLC 248A, 248B for the RF 220A, 220B of a conventional PTP radio include channel frequency, channel bandwidth, and output power level.", "To the extent that a conventional PTP radio employs two polarization feeds within its single antenna, additional parameters may also be controlled by the RLC 248A, 248B as self-evident from the description above.", "In conventional PTP radios, the RLC 248A, 248B decides, usually autonomously, to attempt such parameter changes for the link in response to changing propagation environment characteristics such as, for example, humidity, rain, snow, or co-channel interference.", "There are several well-known methods for determining that changes in the propagation environment have occurred such as monitoring the receive signal strength indicator (RSSI), the number of or relative rate of FCS failures at the MAC 212A, 212B, and/or the relative value of certain decoder accuracy metrics.", "When the RLC 248A, 248B determines that parameter changes should be attempted, it is necessary in most cases that any changes at the transmitter end of the link become known to the receiver end of the link in advance of any such changes.", "For conventional PTP radios, and similarly for many other radios, there are at least two well-known techniques which in practice may not be mutually exclusive.", "First, the RLC 248A, 248B may direct the PHY, usually in the Modem 216A, 216B relative to FIGS.", "2A and 2B, to pre-pend a PHY layer convergence protocol (PLCP) header to a given PPDU that includes one or more (or a fragment thereof) given MPDUs wherein such PLCP header has information fields that notify the receiving end of the link of parameters used at the transmitting end of the link.", "Second, the RLC 248A, 248B may direct the MAC 212A, 212B to send a control frame, usually to a peer RLC 248A, 248B, including various information fields that denote the link adaptation parameters either to be deployed or to be requested or considered.", "The foregoing describes at an overview level the typical structural and operational features of conventional PTP radios which have been deployed in real-world conditions for many radio links where unobstructed (or substantially unobstructed) LOS propagation was possible.", "The conventional PTP radio on a whole is completely unsuitable for obstructed LOS PTP or PMP operation.", "More recently, as briefly mentioned, there has been significant adoption of so called multiple input multiple output (MIMO) techniques, which utilizes spatial multiplexing of multiple information streams between a plurality of transmission antennas to a plurality of receive antennas.", "The adoption of MIMO has been most beneficial in wireless communication systems for use in environments having significant multipath scattering propagation.", "One such system is IEEE802.11n for use in home networking.", "Attempts have been made to utilize MIMO and spatial multiplexing in line of sight environments having minimal scattering, which have generally been met with failure, in contrast to the use of cross polarized communications.", "For example IEEE802.11n based Mesh networked nodes deployed at streetlight elevation in outdoor environments often experience very little benefit from the use of spatial multiplexing due to the lack of a rich multipath propagation environment.", "Additionally, many of these deployments have limited range between adjacent mesh nodes due to physical obstructions resulting in the attenuation of signal levels.", "Radios and systems with MIMO capabilities intended for use in both near line of sight (NLOS) and line of sight (LOS) environments are disclosed in

listing for the frequency availability for specific radio services 47 C.F.R.", "§ 101.101, and a proposed new band of operation for Advanced Backhaul Services (4A-01).", "The new band for Advanced Backhaul Services is not currently listed as a defined service within the table for fixed microwave services.", "Specific embodiments of the disclosed invention for an Advance Backhaul service (ABS) operate within a band from 7125 to 8500 MHz, and include a number of tiered services.", "Currently this band is not under the control of the FCC, but may have fixed point to point services defined for government operation by the Office of Spectrum Management (OSM) within the National Telecommunications & Information Administration (http://www.ntia.doc.gov/office/OSM).", "The OSM manages the Federal government's use of the radio frequency spectrum, and may be thought of as filling a similar role for the federal government as the FCC does for the commercial sector.", "Currently, most of this band is defined as government exclusive operation as can be seen within the NTIA's “Redbook” defining spectrum allocations for use by the Federal government (http://www.ntia.doc.gov/files/ntia/publications/redbook/2013/4b_13.pdf).", "The frequency band (4A-01) is provided as an example only, and other bands of operated are contemplated for use with the embodiments disclosed.", "FIG.", "4B illustrates an exemplary deployment for occupancy of services in the 7125 to 8500 MHZ frequency band for legacy radios and Advanced Backhaul Services (ABS) compliant radios amongst other services.", "The services deployed within this band according to embodiments of the invention, may be time division duplex (TDD), frequency division duplexed (FDD) or zero division duplexed (ZDD).", "FDD systems utilize separate frequency channels for receiving (4B-10) and transmitted signals (4B-50) to each radio, as shown in FIG.", "4B.", "TDD systems utilize a single frequency channel (4B-30) and alternate receiving and transmission with the radio to which they are communicating, allowing for the deployment of such services in the center of the operational band, as shown in FIG.", "4B.", "As previously discussed, ZDD systems utilize signal processing techniques to allow the simultaneous transmitting and receiving of signals on the same frequency channels.", "Generally ZDD systems could utilize similar channels to those of the TDD operating radios, but this is not a requirement and thus ZDD systems may be able to use any of the FDD or TDD channels.", "The spectrum in the embodiment defined in FIG.", "4B is partitioned into 3 Sub-Bands: SB1=7126.5-7574.5 MHz (Channels 1 to 32) SB2=7588.5-8036.5 MHz (Channels 34 to 65) SB3=8050.5-8498.5 MHz (Channels 67-98) Additionally Channels 33 (4B-20) and 66 (4B-40) are defined as Common Control Channels (CCC), to be used for advertising the presence of ABS devices, intercommunication between ABS devices with respect to interference coordination and other control and overhead functions in specific embodiments.", "Channelization In one embodiment, a network-based registry 4C-60/4C-70 (of FIG.", "4C) will provide for a maximum number of channels out of the total number of channels available for operation for use by a particular device (or Tier as will be explained associated with FIG.", "4C), either dependent, or independent of duplex mode of operation.", "As will be discussed associated with subsequent figures, and specific embodiments, ABS services may include multiple groups of “Tiers” of devices, each tier having specific rules by which they must operate and result in interference protection between and among tiers of devices (such devices being referred to as tiered service radios).", "Such rules may also provide for a fairness to access of channels to prevent some devices from unfairly using more spectrum channels than would be fair to other devices, and preventing a reasonable number of devices within a geographic region to operate simultaneously.", "For example, in one embodiment associated with FIG.", "4B, the individual channels of operation are 14 MHz in Bandwidth, as is common for fixed wireless in the United States (ranging from 3.5 MHz, 7 MHz, 14 MHz, etc).", "In other embodiments, such as for use is Europe, channels of 5 MHz, 10 MHz, or other multiples are more common.", "Any given link must use and register up to 2NMAX channels of 14 MHz each from amongst designated channels.", "FDD products typically register to transmit in 2NMAX−1 channels of SB1 in one direction and to transmit in 2NMAX−1 channels of SB3 in the opposite direction for a given link, however FDD products are not required to use this SB1/SB3 duplex approach.", "The selection of the number of channels for operation, as mentioned for some embodiments, may be determined based upon the tier of service a device belongs to, and determined according to parameters provided by accessing a registry and may be specific to a geographic region.", "In one example, for Tier 2 products, NMAX=3 (e.g.", "2NMAX=8) resulting in 8×14 MHz, or 112 MHz would be typical in most geographic regions.", "In a related example, For Tier 3 products, NMAX=2 (e.g.", "2NMAX=4) resulting in 4×14 MHz, or 56 MHz would be typical in most geographic regions.", "The total number of channels that can be used by both transmitters in aggregate for any given link is MTOT=2NMAX.", "In the current embodiment, the MTOT channels can be occupied by either or both transmitters at any time for a given link, and may be dependent on the Tier of service, and geographic region.", "An example of a geographic region is shown in FIG.", "4D by the boundary lines 4D-10, 4D-15, 4D-20, and 4D-25.Continuing with the current exemplary embodiment, MACTUAL is the actual number of channels (up to MTOT), in use at any time.", "Once a tiered service radio (or tiered device) is registered, (thus, becoming a registered radio) to transmit MREG channels in any of SB1, SB2, or SB3, such a product can transmit subject to sharing rules herein, on 1 to MREG channels contiguously as available.", "In the current embodiment, non-contiguous Tx channels at a single transmitter are not allowed.", "According to the rules of the current embodiment, all transmitters (tiered service radios for example) are fixed and registered prior to first usage (including Tier 3 devices).", "In an exemplary embodiment, no devices are mobile.", "In one embodiment, the registration may include Tx location, antenna parameters, Tx channels(s) (or channel numbers), Tx power (or max tx power), signature parameters (such as code sequences, demodulation parameters, structures, identifiable aspects of the signature radio signals, etc.", "), acceptable co-channel sharing signatures (or classes of signatures), Tx signaling method(s), signature approach (inline versus embedded), signature power in dB relative to nominal Tx power level, and/or maximum registered Tx power.", "More detail and specific examples of exemplary registry entries are discussed associated with FIG.", "8A in more detail.", "FIG.", "4C illustrates an exemplary embodiment of Advanced Backhaul Service tiered service radio interconnection with an exemplary ABS device registry database.", "In one embodiment, each tiered service radio (or tiered device) has specific rules and procedures, which are required to be followed, except for a legacy device.", "The tiered service radios provide for interference protection for legacy devices, or from other devices at the same or lower tier.", "Membership to a tier varies based upon the specific tier.", "For example in the embodiment of FIGS.", "4A and 4B, utilizing spectrum with fixed point to point devices operating under existing rules, such devices as currently in use for Federal point to point wireless communications would be deemed to be Tier 1 devices 4C-10.Such currently deployed devices would be deemed “legacy” Tier 1 4C-10, where new devices which also belong to existing government users, would be deemed “incumbent” Tier 1 devices 4C-20, and may have specific requirements for the deployed equipment differing from the currently deployed legacy Tier 1 devices.", "In one embodiment Tier 1 devices 4C-10, 4C-20 would be protected from interference by requiring lower tier devices (4C-30, 4C-40) to perform a registry look up for a specific geographic region.", "Specific criteria, in some embodiments, is passed to the registry so as to retrieve information related to the registered radios on interest.", "In this embodiment, it would be a requirement of the devices, of lower tiers of service performing the registry look up, utilizing specific criteria, to be able to determine, or to be provided, their current geographic coordinates.", "In other embodiments, the specific criteria may be a subset or inquiry criteria and be within the tiered service radio and used to filter the information returned from the registry.", "In further embodiments, specific criteria such as geographic location, tier of the inquiring device, etc., may be passed to the registry as inquiry criteria and the filtering and/or selection of information performed within the registry completely.", "In yet further embodiments, the selection of information from the registry based upon the specific criteria may be performed on one or both of either the inquiring tiered service radio or the registry apart (or in combination).", "Returning to the current description, the only protection a legacy Tier 1 device 4C-10 would have is the registry 4C-70 with a pre-defined exclusion zone associated with a geographic location.", "Such an exclusion zone within may be defined by one or more center points, and a radius from each center point, or another definable geographic shape such as a rectangle, or an ellipse, or the like.", "An example of such an exclusion zone is provided in FIG.", "4D, associated with exclusion zone 4D-35.Exclusion zone 4D-35 provides for an ellipse as defined within the server 4C-60 and registry database 4C-70.Lower tier devices, such as Tier 2 Devices 4C-30 and Tier 3 Devices 4C-40, connect to server 4C-60 and registry database 4C-70 via network connections 4C-35, 4C-45, and 4C-65, and over an interim network 4C-50 in some embodiments.", "Such a network 4C-50 may be a private network, or the public Internet, or both.", "Additionally, Incumbent Tier 1 devices may include a network connection 4C-25 in some embodiments.", "Incumbent Tier 1 Devices 4C-20 may additionally become a registered radio with the registry database 4C-70 in some embodiments, or may transmit an alert message advertising the Incumbent Tier 1 Device's presence, or perform both registration as well as advertisement.", "Such an advertisement may be performed in a number of ways including on the so-called common control channels (4B-20, 4B-40) and associated with FIG.", "4B.", "In other embodiments, alerts may be transmitted inband so as to allow for an accurate assessment of the received signal from the Tier 1 device, and to determine an acceptable transmission power so as to ensure no detrimental interference to the Tier 1 Device.", "An example of Incumbent Tier 1 devices operating utilizing in-band alert transmission is provided associated with FIG.", "4D.", "Incumbent T1 Device (T1-I) 4D-40-A is in communication with T1-I 4D-40-B, both transmitting an alert signal, including information identifying the device and either including the transmitted power within the alert, or retrievable from the registry database.", "Additional information may be included with the transmission or within the registry as well such as locations of the devices, and frequencies or operation, and mode (TDD/FDD/ZDD) of the device, and the like.", "More detail related to embodiments of the registry entries are provided associated with FIG.", "8A.", "For example, such information can be used to determine the propagation path loss to the transmitter or to estimate path loss to potential receivers associated with the stations.", "Tier 2 devices 4D-60-A, 4D-60-B may utilize transmission limits as determined from such parameters so as to operate in closer proximity to the T1-I devices 4D-40-A and B, rather than simply utilizing an exclusion zone.", "Referring back to FIG.", "4C, Tier 2 Devices are registered users (or registered radios) and are provided with a license, which offers interference protection relative to other Tier 2 devices, and Tier 3 devices.", "Tier 2 devices (T2), in some embodiments, have no interference protection from Tier 1 devices (Legacy or Incumbent).", "To receive a license, operators of T2 devices may pay a fee that may be determined by in a number of ways, in various embodiments.", "Such a fee may be based upon: i. number of channels up to a maximum for initial registration, and annual usage per link for a specific geographic region, and/or ii.", "by Auction, and/or iii.", "by Status (such as, for example only, providing a service deemed a public good) Exemplary rules that may be required for Tier 2 devices include: Tier 2 users must not use, or must vacate upon detection, channels occupied by Tier 1 users.", "Tier 2 users must occasionally re-check the registry database (based upon time, duration, or the like).", "Tier 2 devices must advertise their presence by transmitting an Alert signal including a T2 Alert Signature, and registering within the registry data base 4C-70 (or becoming a registered radio), including the start time of their active operation and other details, such as for example, described associated with FIG.", "8A.", "An

the prostheses implanted within the human body can be subjected to infections.", "If this should occur, the infected prosthesis must in fact be removed from the implant site and, before the implant of a new prosthesis, it is necessary to eradicate the infection.", "During such step, spacer devices are normally employed in order to maintain substantially unchanged the shape of the bone site or of the joint site in which the new prosthesis will be implanted, simultaneously releasing substances capable of treating the infection.", "Such procedure is known as “two-stage treatment” for the removal of an infected prosthesis and the implant of a new prosthesis.", "Nevertheless, sometimes, when the bone conditions allow, the surgeon decides to not carry out such procedure in two stages, but rather to apply a one stage treatment according to which, after having removed the infected prosthesis and carried out the “cleaning” of the surgical site, the new prosthesis is immediately inserted into the surgical site, without having first used a spacer device for treating the infection.", "In such case, the new prosthesis can be fixed to the bone of the patient with bone cement, e.g.", "antibiotic bone cement, or it can also only inserted in the bone, in accordance with the specific situations.", "When the prosthesis is inserted in the bone without the use of bone cement, it is more easily removable in case of onset of a new infection.", "Naturally, if the bone conditions are quite compromised, the use of the bone cement for fixing the new prosthesis is substantially required.", "Surgeons who decide to use the “one stage” therapy trust in the fact that the cleaning or renewal of the bone and the systemic antibiotic therapy are sufficient for treating the infection underway or for preventing the onset of a new infection.", "Nevertheless, from studies carried out, it is seen that in this case the reinfection can occur even if in a small percentage, which is different from what occurs with the two stage treatment where the onset of a new infection is an extremely rare occurrence.", "Gels or similar substances are available on the market that are capable of being applied, for example swabbed, on the outer surface of a prosthesis before the implant thereof.", "Such procedure can be applied both on a first insertion prostheses and on revision prostheses, i.e.", "implanted following the explant of a first insertion prosthesis.", "Such gels or substances, while being antibiotic-loaded, are nevertheless ineffective against bacteria since the contact time with the bacteria themselves is overly reduced, in order to cause the death thereof.", "Usually, in fact, such substances are used to prevent bacteria, e.g.", "bacteria present in the outside environment, from being present or settling on the outer surface of the prosthesis, thus preventing the same from entering into the surgical site, even if they are not specifically able to eliminate the bacteria present within the bone or joint site of the implant.", "There is therefore the need for the surgeon to be able to implant prosthetic devices, both first implant and revision prosthetic devices,

respect to the overall size of the prosthetic device 1, so as to not reduce or affect the mechanical properties of the prosthetic device 1 according to the present invention.", "Indeed, the prosthetic device can be positioned during use within a bone or joint site and it must be able to support the weight of the user and/or the movements tied to the area in which it is implanted.", "With respect to a completely solid prosthetic device, e.g.", "a prosthesis of conventional type, therefore, the presence of the inner cavity 5 must not compromise the mechanical properties of the prosthetic device

the entire wall and/or the outer surface 41 of the prosthetic device 1.In the enclosed figures, only some holes or ports 6 are present, without at all limiting the number or arrangement thereof.", "The holes or ports 6 are formed transversely to the wall of the prosthetic body 2, so as to be extended from the inner surface 42 to the outer surface 41 thereof.", "According to one version of the invention, the prosthetic device 1 has a plurality of holes or ports 6.Such ports or holes 6 are adapted to place in communication the space corresponding to the inner cavity 5 with the space outside the prosthetic device 1 or with the bone tissue surrounding the prosthetic device 1 during use.", "In particular, such holes or ports 6 pass through the inner cavity 5 and the space outside the prosthetic device 1 and hence pass through the wall of the prosthetic device 1 or pass from the outer surface 41 to the inner surface 42 thereof.", "The size of the holes or ports 6 are such to allow the passage, in both senses, of liquids or gases, e.g.", "biological liquids, medicated substances, etcetera.", "The inner cavity 5, according to one version of the invention, is adapted to comprise, contain or house a filler material 7.Therefore, in one version of the invention, the prosthetic device 1 comprises a filler material 7, housed in the inner cavity 5.The filler material 7 is in fluid,

medical solution, e.g.", "antibiotic.", "In a still further version of the invention, the filler material 7 comprises a biocompatible semi-solid material comprising a medical substance, such as an antibiotic.", "Such semisolid material can be insoluble (for example bone cement) or soluble, e.g.", "animal collagen, sugars, cellulose, etcetera.", "The main characteristic of such filler material 7 is that of having capillary capacity, i.e.", "of comprising, substantially for the entire volume thereof, small channels with micrometric transverse size (i.e.", "considering the dimension perpendicular to that of greater extension of the small channel itself), capable of absorbing and eluting liquids via capillarity.", "Such small channels can be interconnected and they are preferably interconnected in one version of the invention.", "In one version of the invention, the filler material 7 comprises an acrylic resin and an inorganic salt, such as PMMA (polymethylmethacrylate) and calcium phosphate or tri-calcium phosphate (TCP).", "In one version of the invention, the average cross-section diameter of such small channels is less than 100 microns.", "In FIGS.", "8 and 9, one version of the present invention is illustrated, in which the prosthetic device 1 or the prosthetic body 2 comprises a tibial portion of a knee prosthesis.", "Such version has the same characteristics as that just described above, it only varies with regard to the shape, which is specific for the implant site in which it must be positioned.", "The prosthetic body 2 comprises at least one wall, said wall having an outer surface 41 as well as an inner surface 42 delimiting the inner cavity 5.As prosthetic body, a stem component 2b and a tibial plate component 20 of the tibial portion of a knee prosthesis are depicted, as non-limiting example of the prosthetic device 1 according to the present invention.", "The stem 2b has a substantially tubular wall while the tibial plate component 20 has a substantially box-like wall.", "The prosthetic body 2, in particular the tibial plate component 20, in one version of the invention illustrated as an example in FIG.", "9, is composed of at least two parts: a first portion or shell 2a and a second portion or shell 2c.", "Such first portion or shell 2a and second portion or shell 2c comprise the aforesaid wall which has an outer surface 41, an

are hollow portions.", "Their cavity constitutes the inner cavity 5 of the prosthetic body 2.Therefore, each of such first portion or shell 2a and second portion or shell 2c form a part of the prosthetic body 2 and, once joined together, they constitute the entire prosthetic body 2 and the entire cavity 5 comprised therein.", "As illustrated in FIG.", "9, the second portion or shell 2c also comprises the stem component 2b.", "The first portion or shell 2a is joined with the second portion or shell 2c by means of a respective peripheral edge 2a1 and 2c 1 thereof.", "In FIG.", "9, such peripheral edges 2a1 and 2c 1 lie along a transverse plane IX-IX.", "The stem 2b is adapted to be inserted in the tibial medullary canal, at the knee joint.", "Such prosthetic device could also comprise a femoral portion of a knee prosthesis, not illustrated but configured in a conventional manner, or preferably having the same characteristics of the tibial portion described herein.", "In one version of the invention, also the femoral portion could be composed of a first portion or shell (e.g.", "condylar) and a second portion or shell (e.g.", "of rotation), which, being hollow, delimit an inner cavity.", "Also such portions can be joined by means of respective outer peripheral edges, made in their lateral wall, so as to constitute, once joined, the inner femoral portion of the prosthetic device according to the present invention.", "The stem component 2b protrudes from the tibial plate component 20, in particular from the lower surface thereof, and has elongated shape with a first base end proximal to the tibial plate component 20 as well as a second tip end 4b, so as to have an extension substantially elongated around the longitudinal extension axis of the stem component 2b, from its first end to its second end 4b.", "The inner cavity 5 is delimited within the stem component 2b and within the tibial plate component 20, in order to carry out an improved function.", "In one version of the invention, the cavity 5 can be delimited only with one of said elements.", "The stem component 2b or the tibial plate component 20 or the prosthetic device 1 or the

whose interior it is obtained.", "The inner cavity 5 of the stem component 2b and of the tibial plate component 20 has, in one version of the invention, a substantially continuous shape.", "Also in this version, the prosthetic device 1 according to the present invention further comprises holes or ports 6, with configuration and arrangement analogous to the previously described embodiment.", "In addition, the inner cavity 5 is adapted to contain or house a filler material 7, which has the characteristics indicated in the present description.", "The prosthetic device 1 or the prosthetic body 2 can be made of a biologically compatible material, of the type implantable inside the human body, such as metal, e.g.", "steel or titanium, metal alloys, plastic or acrylic resins, polymer materials, etcetera.", "The material of the prosthetic device 1, in any case, must be able to ensure the necessary mechanical properties, for example for support of the weights and/or for wear resistance, adapted to perform the function of permanent bone prosthesis.", "The prosthetic device or the prosthetic body 2 is massive, and in one version of the invention it does not have planes of junction between its components, for example the stem 2a and the neck portion 3 or between the tibial plate component 20 and the stem 2b, and is hollow.", "In one version of the invention, also the prosthetic body 2 of the device relative to a femoral hip prosthesis can comprise a first portion or shell and a second portion or shell.", "Such portions, being hollow, delimit the cavity 5 at their interior, and once joined together they constitute the entire prosthetic body 2.In such version of the invention, the first portion or shell and the second portion or shell mirror each other.", "The filler material 7 comprises, in one version of the invention, an antibiotic or medical substance.", "For example, the antibiotic is adapted to oppose an infection underway in the implant zone of the prosthetic device 1 or to prevent the onset of an infection.", "In a further version of the invention, the filler material 7 is adapted to absorb, due to the capillarity given by its small channels, a solution containing an antibiotic or medical substance or an antibiotic or medical substance.", "In addition, the presence of the small channels of the filler material 7 and of the holes or ports 6 of the prosthetic device 1 allows the antibiotic or medical substance or the solution comprising the same, contained in the filler material 7, to be eluted or delivered outside the prosthetic device 1, i.e.", "towards the bone tissue or towards the joint space of the implant site.", "The antibiotic substance or medical substance exits from the prosthetic device 1 by means of the holes or ports 6.If the filler material 7 also comprises calcium or other inorganic salts, together with the delivery of the antibiotic or the medical substance, also such calcium or such salts or ions thereof can be eluted or delivered.", "Such inorganic substances are beneficial for the surrounding bone tissue with which they come into contact.", "The filler material 7 (and at least partially, in some versions, the material of the prosthetic device 1) absorbs the antibiotic or medical substance.", "Therefore, in one version of the invention, the filler material 7 is absorbent.", "According to a further version of the invention, the filler material 7 is porous.", "The inner cavity 5, and the filler material 7, therefore act as a tank for the antibiotic or medical substance or for the solution containing the same, which is then released by the spacer device 1 through the holes or ports 6.In the exemplifying version illustrated in FIGS.", "1-7, the stem component 2a is made of a single piece with the neck portion 3.This aspect is tied to the need, for the prosthetic device 1, to sustain the stresses due to the support of the user's weight.", "Specifically, in fact, the neck portion 3 is the maximum stress zone, in the case of a hip prosthesis.", "As stated above, a hip prosthesis of conventional type comprises a hemispherical head adapted to articulate with the acetabular cup or the acetabulum of the hip.", "Also such hemispherical head, not illustrated in the figures, can be made according to the present invention, i.e.", "comprising an inner cavity, this time with shape corresponding to that of the head, and hence at least partially hemispherical, adapted to contain the filler material and thus the antibiotic or medical substance.", "In order to allow the exit of the antibiotic or medical substance or of the solution containing the same, the head comprises holes or ports with size such to not interfere with the rotation movement and/or partial translation of the head itself in its joint implant zone.", "Such prosthetic device 1, due to its particular structure and to the filler material 7 contained therein, allows having a greater exposure, in terms of time and/or of concentrations, to antibiotic or medical substance.", "Therefore, unlike what occurs for the prostheses of the prior art, it is possible to cure an infection underway in the bone tissue relative to the implant site, or to prevent the onset of a new infection.", "Indeed, the delivery/elution of the antibiotic or medical substance lasts for at least one day.", "In FIGS.", "10a, 10b and 11, an acetabular version of the present invention is illustrated, in which the prosthetic device 1 or the prosthetic body 2 comprises an acetabular cup 50 or acetabular portion of a hip prosthesis.", "The acetabular cup 50 has dome or hemispherical shape; it constitutes the upper part of a total hip prosthesis.", "The acetabular cup 50, during use, is inserted and/or fixed in the acetabular cavity or cup, at the pelvis of the patient.", "Such version has the same characteristics as that just described above, but it varies with regard to shape, which is specific for the implant site where it must be positioned.", "The prosthetic body 2 comprises at least one wall, said wall having an outer surface 41 as well as an inner surface 42 delimiting the inner cavity 5.In particular, the outer surface 41 of the acetabular cup 50 is convex and adapted to come into contact with the bone of the patient; the inner surface 42 is concave, and adapted to be joined, possibly by means of interposition of a joint insert 60, with the head of the hip prosthesis connected to the femoral component thereof.", "The inner surface 42 delimits a joint cavity with hemispherical shape, substantially complementary to that of the prosthetic head of the hip prosthesis.", "The thickness of the wall of the acetabular cup 50, delimited between the outer surface 41 and the inner surface 42, houses the holes or ports 6 and a plurality of cavities 5.In particular, the holes or ports 6 have a configuration and arrangement analogous to the previously described.", "The cavities 5 have, in this version, a shape substantially hemispherical or in any case they correspond with a space at whose interior it is possible to house the filler material 7.In particular, a cavity 5 is present at one hole or port 6, or a cavity 5 is present at some holes or ports 6 close to each other.", "In a further version of the invention, the inner cavity 5 has a substantially continuous shape, corresponding to the inner surface 42 of the acetabular cup 50.As stated above, the at least one inner cavity 5 is adapted to contain or house a filler material 7, which has the characteristics indicated in the present description.", "Outside of the acetabular cup 50, at the bone tissue and at the outside opening of the holes or ports 6, a zone 7a is delimited for the absorption and subsequent elution of an antibiotic or medical substance or a solution comprising an antibiotic or medical substance, possibly contained in the filler material 7.At the inner surface 42 of the acetabular cup 50, a joint insert 60 can be present.", "The joint insert 60 is an insert made of ceramic or polyethylene which articulates with the head of the hip prosthesis.", "Indeed, such joint insert 60 ensures a smooth sliding surface with limited friction, in order to facilitate the sliding of the prosthetic head and hence the movements of the hip joint of the patient.", "When present, the joint insert 60, inserted in contact with the inner surface 42 of the acetabular cup 50, closes the at least one cavity 5 from the inner side in a manner such that the zone 7a for the absorption and subsequent elution of an antibiotic or medical substance or a solution comprising an antibiotic or medical substance is only directed towards the outside of the acetabular cup 50.The present invention further refers to a kit comprising the above described prosthetic device 1 and the filler material 7.Finally, the present invention refers to a method for obtaining a prosthetic device 1 according to the present invention, comprising the steps of arranging a prosthetic device 1, suitable for being implanted in a bone or joint site of the human body, and arranging a filler material 7.Such step for arranging the prosthetic device 1 comprises, in one version of the invention, arranging a first portion or shell of the prosthetic body 2 and a second portion or shell of the prosthetic body 2.Such first and second portion or shell delimit the inner cavity 5 of the prosthetic device 1 or each delimits a semi-cavity.", "In such version, the first portion or shell is joined with the second portion or shell in a manner so as to obtain a single prosthetic body 2 that is internally hollow.", "The joining of the first portion or shell to the second portion or shell can occur via welding or melting or softening of the materials that constitute the prosthetic body 2.The method then provides for inserting, for example by means of injection or positioning, the filler material 7 in the inner cavity 5 of the prosthetic device 1.The filler material 7 can be inserted or positioned in the prosthetic device 1 through an opening 30 or multiple openings 30 suitably arranged therein.", "In the version in which the prosthetic device 1 is a hip prosthesis, such opening 30 is provided at the second tip end 4 of the stem component 2a.", "When instead the prosthetic device is a tibial portion of a knee prosthesis, such opening 30 is provided in the end of the stem 2b, adapted to penetrate into the tibial medullary canal.", "Possibly, the filler material 7 is allowed to harden, once inserted or positioned in the aforesaid inner cavity 5.Once the filler material 7 is inserted or positioned, the surgeon can immerse the prosthetic device 1 within a solution comprising an antibiotic or medical substance, in a manner such that the same can penetrate by means of the holes or ports 6 within the prosthetic device and then, via capillarity, within the filler material 7.In one version of the invention, the filler material 7 is soaked with the aforesaid solution.", "In such a manner, once the prosthetic device 1 is implanted in the human body, the solution containing an antibiotic or medical substance will be released by the filler material 7 and can exit, always through the holes or ports 6, towards the surrounding bone tissue, where it will carry out its antibiotic or antimicrobial function.", "An advantage conferred by the present invention is the fact that the antibiotic or medical substance is substantially delivered by the entire surface of the prosthetic device in contact with the bone tissue or is in any case capable of reaching all the bone tissue in contact with the prosthetic device according to the present invention.", "Studies conducted in the field have in fact revealed that the bone tissue absorbs, in a concentrated manner, all the antibiotic molecules (even only a few) that come into contact therewith.", "In such case, the quantity of antibiotic or medical substance locally reaches the effective concentration for eradicating the infection.", "For this reason, it is essential that the holes or ports 6 are substantially present over the entire outer surface of the prosthetic device 1, in a manner such to be extended over the entire area of contact with the bone tissue and thus, if present, of the infection.", "The given definition of “porous” element, present in the present description, can be substituted with “semi-permeable”, without departing from the protective scope of the present invention.", "The invention thus conceived is susceptible of numerous modifications and variants, all falling within the scope of the inventive concept.", "The characteristics presented for one version or embodiment can be combined with the characteristics of another version or embodiment, without departing from the protective scope of the present invention.", "In addition, all details can be substituted with other technically equivalent elements.", "In practice, the materials used, as well as the contingent shapes and sizes, can be of any type in accordance with the requirements, without departing from the protective scope of the following claims." ] ]

deposit seeds into the soil.", "For example, certain agricultural implements include row units configured to open the soil, dispense seeds into the soil opening, and re-close the soil.", "Such implements are generally coupled to a tow vehicle, such as a tractor, and pulled through a field.", "In certain configurations, seeds are conveyed to the row units by the illustrated air cart 10, which is generally towed in sequence with the implement.", "In certain configurations, the air cart 10 may be configured to provide fertilizer to the row units, or a combination of seeds and fertilizer.", "In the illustrated embodiment, the air cart 10 includes a storage tank 12, a frame 14, wheels 16, a metering system 18, and an air source 20.In certain configurations, the storage tank 12 includes multiple compartments for storing various flowable particulate materials.", "For example, one compartment may include seeds, such as canola or mustard, and another compartment may include a dry fertilizer.", "In such configurations, the air cart 10 is configured to delivery both the seeds and fertilizer to the implement.", "The frame 14 includes a towing hitch configured to couple to the implement or tow vehicle.", "As discussed in detail below, seeds and/or fertilizer within the storage tank 12 are gravity fed into the metering system 18.The metering system 18 includes one or more meter rollers that regulate the flow of material from the storage tank 12 into an air flow provided by the air source 20.The air flow then carries the material to the implement by pneumatic conduits.", "In this manner, the row units receive a supply of seeds and/or fertilizer for deposition within the soil.", "FIG.", "2 is a schematic view of the metering system 18, as shown in FIG.", "1.As illustrated, the air source 20 is coupled to a conduit 22 configured to flow air 24 past the metering system 18.The air source 20 may be a pump or blower powered by an electric or hydraulic motor, for example.", "Flowable particulate material 26 (e.g., seeds, fertilizer, etc.)", "within the storage tank 12 flows by gravity into the metering system 18.In certain embodiments, the storage tank 12 is pressurized such that a static pressure in the tank 12 is greater than a static pressure in the conduit 22, thereby facilitating an even flow of material through the metering system 18.The metering system 18 includes one or more meter rollers 28 configured to regulate the flow of material 26 into the air flow 24.For example, certain metering systems 18 may include ten meter rollers 28, each disposed within an independent seed meter and each configured to flow particulate material into a respective conduit 22 for distribution to one or more respective row units of the agricultural implement.", "Such metering systems are known as “10-run” metering system.", "However, in alternative embodiments, the metering system 18 may include more or fewer meter rollers, e.g., 5, 6, 7, 8, 9, 11, or more.", "As illustrated, the meter roller 28 includes an interior cavity 30 configured to receive a shaft that drives the meter roller 28 to rotate.", "In the present embodiment, the cavity 30 has a hexagonal cross section.", "However, alternative embodiments may include various other cavity configurations (e.g., triangular, square, keyed, splined, etc.).", "The shaft is coupled to a drive unit, such as an electric or hydraulic motor, configured to rotate the meter roller 28.Alternatively, the meter roller 28 may be coupled to a wheel 16 by a gear assembly such that rotation of the wheel 16 drives the meter roller 28 to rotate.", "Such a configuration automatically varies the rotation rate of the meter roller 28 based on the speed of the air cart 10.The meter roller 28 also includes multiple flutes 32 and recesses 34.The number and geometry of the flutes 32 are particularly configured to accommodate the material 26 being distributed.", "The illustrated meter roller 28 includes six flutes 32 and a corresponding number of recesses 34.Alternative embodiments may include more or fewer flutes 32 and/or recesses 34.For example, the meter roller 28 may include 2, 4, 6, 8, 10, 12, 14, 16, 18, 20, or more flutes 32 and/or recesses 34.In addition, the depth of the recesses 34 and/or the height of the flutes 32 are configured to accommodate the material 26 within the storage tank 12.For example, a meter roller having deeper recesses 34 and fewer flutes 32 may be employed for larger seeds, while a meter roller having shallower recesses 34 and more flutes 32 may be

axis) may also be particularly selected to accommodate the material 26.For a particular meter roller configuration, the rotation rate of the meter roller 28 controls the flow of material 26 from the meter roller into the air stream 24.For example, as the meter roller 28 rotates, the meter roller transfers material through an opening 36 in the metering system 18 into a respective conduit 22 (e.g., into a conduit associated with a respective row unit or group of row units).", "The material then mixes with air from the air source 20, thereby forming an air/material mixture 38.The mixture then

axis 58 drives each third gate to transition (e.g., move) between an open position that facilitates material flow to the second conduit connector 48 and a closed position that blocks material flow to the second conduit connector 48.In the illustrated embodiment, the flow control assembly 50 includes multiple handles 60 configured to actuate respective gate control rods 52, 54, and 56.As discussed in detail below, an operator may actuate each handle (e.g., move the handle along the lateral axis 58), thereby driving the corresponding gate control rod to translate along the lateral axis 58.For example, the first gates may be opened by moving a first handle to a position corresponding to an open position of the first gates, and the first gates may be closed by moving the first handle to a position corresponding to a closed position of the first gates.", "The second and third gates may be opened and closed in a similar manner.", "However, it may be undesirable to open more than one set

opening at the bottom of the seed meter.", "However, if the second or third gates are open during the clean-out procedure, the material may drain into the respective conduits, which may at least partially block flow through the conduits during subsequent seeding operations.", "Accordingly, in the illustrated embodiment, the flow control assembly 50 includes a locking assembly 62 configured to

meter roller 28 configured to control a flow of particulate material into the first conduit connector 46 or into the second conduit connector 48 via rotation of the meter roller 28.To determine a relationship between meter roller rotation and particulate material flow rate (e.g., into the first conduit connection 46 or into the second conduit connection 48), the meter roller 28 may be calibrated (e.g., prior to operation of the air cart, periodically, etc.).", "The calibration process includes rotating the meter roller 28 through a desired number of rotations, weighing the particulate material output by the meter roller, and then dividing the material weight by the desired number of rotations to determine a product flow rate (e.g., product weight per meter roller rotation).", "For example, the meter roller 28 may be driven to rotate such that particulate material flows through the opening 36 in a direction 66.The material then exits the seed meter 40 in a direction 68 through an opening 70.An operator may collect the material output through the opening 70, weigh the material, and then determine the product flow rate (e.g., based on the number of meter roller rotations that produced the material output).", "Once the calibration process is complete, the operator may open a second gate 72 to direct the material into the first conduit connector 46

first conduit connector 46, to an open position, which facilitates flow into the first conduit connector 46.With the second gate 72 in the open position, the gate 72 engages a recess 76 in the seed meter 40, thereby directing the flow of material from the direction 66 into the first conduit connector 46 in the direction 78 and blocking the flow of material through the opening 70.Upon completion of seeding operations, or if material flow into the second conduit connector 48 is desired, the second gate 72 may be returned to the closed position, as illustrated.", "If material flow into the

the flow of material through the opening 70.Upon completion of seeding operations, or if material flow into the first conduit connector 46 is desired, the third gate 80 may be returned to the closed position, as illustrated.", "Once seeding operations are complete, a seed gate positioned above the inlet 44 may be transitioned to a closed position to block material flow into the seed meter 40.The material remaining in the seed meter 40 may then be discharged via a clean-out process.", "Alternatively, the seed gate may remain open such that the material from the tank discharges through the seed meter.", "The clean-out process includes closing the second and third gates 72 and 80, and then opening a first gate 87.As illustrated, the first gate 87 may be rotated in a direction 88 from the illustrated closed position, which blocks material from bypassing the meter roller 28, to an open position, which establishes an opening 90.The opening 90 enables material to bypass the meter roller 28 and flow in a direction 92 toward the opening 70, thereby discharging the remaining material from the seed meter 40.As previously discussed, it is desirable to transition the second gate 72 and the third gate 80 to the closed position prior to opening the first gate 87 such that the remaining particulate material does not enter the first conduit connector 46 or the second conduit connector

layers and adhesive layers are realizable.", "This is interesting in particular when gaps in different planes, independent of the material thickness of a foil, are necessary.", "At the end of the method at least one data carrier, e.g.", "a SIM card or a credit card is punched out from the at least one folded and bonded foil.", "Alternatively to the punching, any other suitable method can be used for separating data carriers from the folded and bonded foil, e.g.", "separating by means of laser or water jet.", "According to the invention, during the above-described procedure of folding at least one foil 2 at least one security element is arranged on at least one outer side and/or in the interior of the data carrier to be manufactured.", "For reasons of clarity, a representation of a security element in FIG.", "1 has been omitted.", "The security element is supplied to the procedure described above from a roll or as bulk material.", "The security element is supplied such that it is incorporated into an area 6, 8 of the foil 2, which is coated with adhesive.", "Alternatively, the security element may be embossed into at least one foil 2 of the data carrier.", "The security element may effect a chemical, optical or haptic reaction when used.", "As a security feature which effects a chemical reaction there may be used, for example, a scented lacquer, a color indicator, a

system.", "The system can operate in a home, a nursing home, or a hospital.", "In this system, one or more mesh network appliances 8 are provided to enable wireless communication in the home monitoring system.", "As shown in FIG.", "1A, a mesh network of sensors 8A-8R is shown.", "One implementation of mesh network is a ZigBee mesh network, which is discussed in more details in FIG.", "2 below.", "ZigBee is built on an Institute of Electrical and Electronics Engineers (IEEE) global standard, 802.15.4, similar to the standards that govern Bluetooth and Wi-Fi.", "Open standards encourage innovation and competition, which bring down costs.", "Unlike Bluetooth and Wi-Fi networks, which require central hubs that distribute information to dispersed devices, ZigBee allows devices to form mesh networks, where each unit can relay information to its neighbors.", "Mesh networks are more robust than their hub-and-spoke counterparts; if a node breaks down, other nodes can automatically reroute transmissions around it.", "Mesh networking could let ZigBee systems link as many as 64,000 devices; Bluetooth networks, by contrast, are limited to just eight.", "The mesh network includes one or more mesh network wearable medical appliances 8A which can monitor physiological measurements such as EKG, EMG, EEG, bio-impedance sensor, heart rate sensor, blood pressure sensor, or insulin sensor, among others.", "More details on these devices are described in commonly owned, co-pending applications that are incorporated by reference above.", "Appliances 8A in the mesh network can be one of multiple portable physiological transducer, such as a blood pressure monitor, heart rate monitor, weight scale, thermometer, spirometer, single or multiple lead electrocardiograph (ECG), a pulse oxymeter, a body fat monitor, a cholesterol monitor, a signal from a medicine cabinet, a signal from a drug container, a signal from a commonly used appliance such as a refrigerator/stove/oven/washer, or a signal from an exercise machine, such as a heart rate.", "As will be discussed in more detail below, one appliance is a patient monitoring device that can be worn by the patient and includes a single or bi-directional wireless communication link, generally identified by the bolt symbol in FIG.", "1, for transmitting data from the appliances 8 to the local hub or receiving station or base station server 20 by way of a wireless radio frequency (RF) link using a proprietary or non-proprietary protocol.", "The mesh network includes an in-door positioning 8B.", "The system has two or more wireless mesh network nodes that communicate with a mobile mesh network node.", "The radio signal strength indication (RSSI) is used to determine distance between two nodes, and triangulation is used to determine position.", "A localization process can be used to improve the position determination.", "In one embodiment, the mobile node periodically sends out packets containing RSSI and accelerometer data.", "The other two nodes receive the packets.", "After a packet is successfully received, RF signal strength RSSI reading is determined.", "The resulting signal strength measurements from the fixed sensing nodes are used to determine the wearer's location.", "Due to uncertainty associated with noisy data and the signal strength's nonlinearity, a probabilistic Monte Carlo localization technique to implement a particle filter to localize the location.", "Particle filters work by first distributing random samples called particles over the space being observed.", "Each particle represents a possible physical location in the environment.", "A probability value is assigned to each particle.", "This probability represents the likelihood that the person is at the location specified by the particle.", "At each time step, each particle is reevaluated and its probability value is updated according to the ZigBee signal strength measurements.", "Less likely particles are then redistributed around more likely particles.", "This is done by building a cumulative sum graph of the normalized probabilities of each particle.", "This graph is then randomly sampled to create a histogram that dictates where the particles should be distributed at the next time step.", "The particles concentrate around locations that have a higher probability of being the person's location.", "After the particles have their new coordinates, a small amount of random noise is added to each particle's location so that they're distributed around likely locations instead of concentrating at a single point.", "The location of the person resides at the intersection of two imaginary spheres centered at each of the sensing nodes, with radii proportional to the signal strength.", "The in-door positioning system 8B links one or more mesh network appliances to provide location information.", "Inside the home or office, the radio frequency signals have negligible multipath delay spread (for timing purposes) over short distances.", "Hence, radio strength can be used as a basis for determining position.", "Alternatively, time of arrival can be used to determine position, or a combination of radio signal strength and time of arrival can be used.", "Position estimates can also be achieved in an embodiment by beamforming, a method that exchanges time-stamped raw data among the nodes.", "While the processing is relatively more costly, it yields processed data with a higher signal to noise ratio (SNR) for subsequent classification decisions, and enables estimates of angles of arrival for targets that are outside the convex hull of the participating sensors.", "Two such clusters of ZigBee nodes can then provide for triangulation of distant targets.", "Further, beamforming enables suppression of interfering sources, by placing nulls in the synthetic beam pattern in their directions.", "Another use of beamforming is in self-location of nodes when the positions of only a very small number of nodes or appliances are known such as those sensors nearest the wireless stations.", "In one implementation where each node knows the distances to its neighbors due to their positions, and some small fraction of the nodes (such as those nearest a PC with GPS) of the network know their true locations.", "As part of the network-building procedure, estimates of the locations of the nodes that lie within or near the convex hull of the nodes with known position can be quickly generated.", "To start, the shortest distance (multihop) paths are determined between each reference node.", "All nodes on this path are assigned a location that is the simple linear average of the two reference locations, as if the path were a straight line.", "A node which lies on the intersection of two such paths is assigned the average of the two indicated locations.", "All nodes that have been assigned locations now serve as references.", "The shortest paths among these new reference nodes are computed, assigning locations to all intermediate nodes as before, and continuing these iterations until no further nodes get assigned locations.", "This will not assign initial position estimates to all sensors.", "The remainder can be assigned locations based on pairwise averages of distances to the nearest four original reference nodes.", "Some consistency checks on location can be made using trigonometry and one further reference node to determine whether or not the node likely lies within the convex hull of the original four reference sensors.", "In two dimensions, if two nodes have known locations, and the distances to a third node are known from the two nodes, then trigonometry can be used to precisely determine the location of the third node.", "Distances from another node can resolve any ambiguity.", "Similarly, simple geometry produces precise calculations in three dimensions given four reference nodes.", "But since the references may also have uncertainty, an alternative procedure is to perform a series of iterations where successive trigonometric calculations result only in a delta of movement in the position of the node.", "This process can determine locations of nodes outside the convex hull of the reference sensors.", "It is also amenable to averaging over the positions of all neighbors, since there will often be more neighbors than are strictly required to determine location.", "This will reduce the effects of distance measurement errors.", "Alternatively, the network can solve the complete set of equations of intersections of hyperbola as a least squares optimization problem.", "In yet another embodiment, any or all of the nodes may include transducers for acoustic, infrared (IR), and radio frequency (RF) ranging.", "Therefore, the nodes have heterogeneous capabilities for ranging.", "The heterogeneous capabilities further include different margins of ranging error.", "Furthermore, the ranging system is re-used for sensing and communication functions.", "For example, wideband acoustic functionality is available for use in communicating, bistatic sensing, and ranging.", "Such heterogeneous capability of the sensors 40 can provide for ranging functionality in addition to communications functions.", "As one example, repeated use of the communications function improves position determination accuracy over time.", "Also, when the ranging and the timing are conducted together, they can be integrated in a self-organization protocol in order to reduce energy consumption.", "Moreover, information from several ranging sources is capable of being fused to provide improved accuracy and resistance to environmental variability.", "Each ranging means is exploited as a communication means, thereby providing improved robustness in the presence of noise and interference.", "Those skilled in the art will realize that there are many architectural possibilities, but allowing for heterogeneity from the outset is a component in many of the architectures.", "A mesh network motion detector 8C can be used in the network.", "FIG.", "1B shows an exemplary system that includes an active or passive motion sensor connected to a wireless mesh network processor.", "For certain applications such as night guide light, the wireless mesh network processor can control an optional light emitter such as a light bulb or LED array for evening lighting purposes when motion is detected.", "For ease of placement, the system can include an energy collector or harvester device such as a solar cell to power the entire system.", "The motion sensors can be grouped into two categories.", "The first are passive devices, such as PIR systems, stereoscopic vision and swept-focus ranging systems.", "The second are active devices, such as laser, microwave and ultrasonic range finding systems.", "In one embodiment, the sensor can be an ultrasonic ranging device such as a Polaroid ranging module.", "This device is an active time-of-flight device developed for their cameras to allow automatic camera focusing.", "It determines the range to a target by measuring elapsed time between the transmission of a “chirp” of pulses and a detected echo.", "The one millisecond chirp consists of four discrete frequencies composed of 8 cycles at 60 KHz, 8 cycles at 56 KHz, 16 cycles at 52.5 KHz, and 24 cycles at 49.41 KHz.", "This pulse train increases the probability of signal reflection from a wide range of targets.", "In another embodiment, the motion sensor can be a radio detection and ranging (RADAR) K-Band microwave RF (radio frequency) transmitter whose signal gets reflected by the target person.", "The reflected signal will have a Doppler shift proportional to the target speed.", "This Doppler frequency shift is detected in the receiver, amplified, filtered, and then digitized in an analog-to-digital converter (ADC), and passed onto the digital signal processing (DSP) chip.", "The DSP chip filters out false and low-level return signals to identify the speed of the person.", "The speed, along with various statistics and averages, is then sent over the wireless mesh network.", "In one implementation, the sensor sends out high frequency (such as 24 GHz) radio waves and measures the difference between the signal it transmitted and the signal bounced back to it and relays this information to the DSP to determine the speed of the individual.", "In yet another embodiment, a microwave signal is used to detect motion.", "FIG.", "1C shows one implementation of a PIR motion sensor.", "A pyroelectric sensor is used with a crystalline material that generates a surface electric charge when exposed to heat in the form of infrared radiation.", "When the amount of radiation striking the crystal changes, the amount of charge also changes and can then be measured with a sensitive FET device built into the sensor.", "The sensor has two sensing elements connected in a voltage bucking configuration.", "This arrangement cancels signals caused by vibration, temperature changes and sunlight.", "A body passing in front of the sensor will activate first one and then the other element whereas other sources will affect both elements simultaneously and be cancelled.", "The radiation source must pass across the sensor in a horizontal direction when sensor pins 1 and 2 are on a horizontal plane so that the elements are sequentially exposed to the IR source.", "The FET source terminal pin 2 connects through a pulldown resistor of about 100 K to ground and feeds into a two stage amplifier having signal conditioning circuits.", "The amplifier is typically bandwidth limited to below 10 Hz to reject high frequency noise and is followed by a window comparator that responds to both the positive and negative transitions of the sensor output signal.", "A filtered power source of from 3 to 15 volts should be connected to the FET drain terminal pin 1.One exemplary device is the RE200B PIR sensor and an exemplary module is the QK76 PIR Motion Detector Module, available from Q Kits Ltd. Of Kingston Ontario, whose output is an active high pulse of approximately 0.5 seconds and remains active as long as there is motion.", "A focusing lens is used in front of the sensor to focus thermal energy.", "The output of the sensor is provided to an amplifier, which output is provided to a mesh network wireless chip such as a single chip ZigBee transceiver with processor available from Freescale or Texas Instrument (ChipCon).", "The ZigBee chip can receive data from a photodiode and control a light emitter (such as LED array or light bulb) to provide night lighting in one option.", "This embodiment can also optionally harvest solar energy to charge the device when light is available.", "A combination of active and passive motion sensors can be used for the mesh network motion detector 8C.", "They inject energy (light, microwaves or sound) into the environment in order to detect a change.", "In one embodiment, a beam of light crosses the room near the door, and a photosensor on the other side of the room detects the beam.", "When a person breaks the beam, the photosensor detects the change in the amount of light and sends a signal over the mesh network.", "In another embodiment, a radar detects when someone passes near the door.", "The radar sends out a burst of microwave radio energy and waits for the reflected energy to bounce back.", "When a person moves into the field of microwave energy, it changes the amount of reflected energy or the time it takes for the reflection to arrive, and the radar sends a signal over the mesh network to indicate a person is crossing the zone and optionally opens the door.", "Similarly, an ultrasonic transducer can be used to send sound waves, bouncing them off a target and waiting for the echo.", "Passive motion sensors can be used as well.", "In one embodiment, the motion sensing such as those on lights (and security systems) is a passive system that detects infrared energy.", "These sensors are known as PIR (passive infrared) detectors or pyroelectric sensors.", "The sensor is sensitive to the temperature of a human body which has a skin temperature of about 93 degrees F. and radiates infrared energy with a wavelength between 9 and 10 micrometers.", "Therefore, the sensors are typically sensitive in the range of 8 to 12 micrometers.", "The sensor can be a photo-sensor—the infrared light bumps electrons off a substrate, and the electrons are detected and amplified into a signal that is then sent over the mesh network to the controller.", "The sensor looks for a rapid change in the amount of infrared energy.", "When a person walks by, the amount of infrared energy in the field of view changes rapidly and is detected.", "The motion sensor can be a wide field of view by using suitable lens covering the sensor to focus and bend light through plastic lenses.", "In a basic embodiment, a single motion sensor 8C can be placed between the bed of the user and the bathroom.", "In a case where only a door sensor 8D is provided within the system, the door sensor 8D can be placed on the door of the bathroom.", "Such basic configuration can determine whether the user being monitored has gotten out of bed or has gone to the bathroom after a predetermined time.", "The daily living activity is captured and the information is captured for pattern analysis by the base station 20.For example, the pattern analysis can determine if the user remains in bed a specified length of time beyond the usual waking time or has not gone from the bed to the bathroom for a predetermined time period.", "If an abnormal lack of user activity is determined, the system can request the third-party 210 to take preventive action.", "A status report can be sent to the third party 210 indicating a potential problem with the patient.", "A mesh network door sensor 8D can transmit door opening/closing to the base station 20.The door sensor can be magnetic sensors, or can be a wire that complete a circuit when the door is closed, can be an optical beam that is interrupted when the door moves, a reed-switch that detects door movement, or can be any suitable method to detect door opening or closing.", "The system can also be applied to windows to detect window opening and closing.", "A mesh network bathroom motion detector 8E is provided to detect motions within a specific room, in this case a bathroom.", "Room specific sensors such as a mesh network bathroom water overflow sensor 8F can be provided.", "In one embodiment, a pair of wires is positioned on the bathroom floor and when liquid shorts the wires, a signal is sent over the mesh network to indicate bathtub overflow problem.", "Other room specific sensors can include a toilet sensor (not shown).", "The toilet sensor can simply detect lid opening/closing operations.", "In another implementation, the toilet sensor can include piezoelectric sensors that sense the viscosity of the patient excrements.", "In yet other implementations, the toilet sensor includes temperature sensor or other chemical analyzers that determine the composition or indicators thereof and forward the information over the mesh network.", "The system also receives information from mesh network enabled exercise equipment 8G.", "Data transmitted by the equipment can include the length of the exercise, the type of

temporal window which is chosen based on the range of the echo-producing entity in relation to the acoustic source.", "The delay time before the gate is turned on determines the depth of the sample volume.", "The amount of time the gate is activated establishes the axial length of the sample volume.", "Thus, as the acoustic source (in this case the ultrasonic transducer 84) is tuned to the

collet chuck, and, further, the tensile force can be effectively applied to the balloon.", "Another aspect of the present disclosure involves a balloon rotating method for rotating a balloon catheter.", "The balloon catheter includes a balloon possessing an axis and an inner tube passing through the balloon, with the balloon possessing one end portion axially overlapping and connected in a fluid-tight manner to the inner tube at a connection portion.", "The balloon rotating method comprises: clamping the connection portion by at least two clamping portions each including a groove-shaped curved surface extending along the axis of the inner tube; and rotating the balloon about the axis of the balloon while the connection portion is clamped by the clamping portions.", "According to the balloon rotating method configured as above, the connection portion between the inner tube and the balloon is pulled by fixing it in the manner of being clamped by the clamping portions each having the groove-shaped curved surface.", "Therefore, the inner tube and a part of inflation of the balloon are not damaged and can be restrained from becoming eccentric, so that the position of the outer surface of the balloon becomes less liable to fluctuate during rotation.", "The balloon rotating method may have a configuration wherein as a part of the rotating, the balloon is rotated while pulling the balloon in an axial direction of the balloon by the clamping portions.", "In this case, a bend, if any, of the balloon is straightened by the tensile force, so that the position of the outer surface of the balloon is not liable to fluctuate during rotation.", "In addition, although the clamping force by the clamping portions is increased because the tensile force is

apparatus configured to form a coating layer containing a water-insoluble drug on an outer surface of a balloon of a balloon catheter includes: at least two clamping portions configured to fix, in the manner of clamping, a connection portion between the balloon and an inner tube penetrating an inside of the balloon, the clamping portions each having a groove-shaped curved surface extending along an axis of the inner tube; a rotation driving section configured to rotate the balloon catheter; and a coating section that moves a dispensing tube for supplying a coating liquid containing the drug

detailed description of embodiments of a balloon coating method and a balloon rotating method for forming a drug-containing coating layer on a balloon surface representing examples of the inventive balloon coating method and balloon rotating method disclosed here.", "Dimensional ratios in the drawings may be exaggerated for convenience of explanation and may therefore be different from the actual ratios.", "First Embodiment A balloon coating method according to a first embodiment of the present disclosure is a method of forming a coating layer containing a water-insoluble drug on a surface of a balloon, and is carried out by a balloon coating apparatus 100 illustrated in FIG.", "1.In the description below, the end of a balloon catheter 10 that is inserted into a body lumen will be referred to as the “distal end” or “distal side,” and the end at which the operator's hand operation occurs will be referred to as the “proximal end” or “proximal side.” First of all, the structure of the balloon catheter 10 will be described.", "The balloon catheter 10 is a so-called rapid exchange type catheter.", "As illustrated in FIGS.", "2 and 3, the balloon catheter 10 includes an elongate catheter shaft 20 (shaft), a balloon 30 provided on a distal portion of the catheter shaft 20, a hub 40 firmly attached (fixed) to a proximal end of the catheter shaft 20, and an anti-kinking tube 50 provided at a joint portion between the catheter shaft 20 and the hub 40.The catheter shaft 20 includes a tube-shaped (tubular) proximal shaft 60 whose proximal end is firmly attached (fixed) to the hub 40, a tube-shaped (tubular) intermediate shaft 70 covering a distal side or distal end of the proximal shaft 60, a tube-shaped (tubular) distal shaft 80 provided on the distal side of the intermediate shaft 70, and a tube-shaped (tubular) inner tube 90 disposed inside the distal shaft 80.Inside the proximal shaft 60, the intermediate shaft 70 and the distal shaft 80 is an inflation lumen 23 through which an inflation fluid for inflating the balloon 30 flows.", "The inner tube 90 includes an inner tube shaft 95 which penetrates the inside of the distal shaft 80 and the balloon 30 in a coaxial manner, and a flexible tip 96 interlocked to a distal portion of the inner tube shaft 95.The tip 96 extends distally beyond the distal end of the balloon 30, and a distal portion of the balloon 30 is joined to an outer circumferential surface of a proximal portion of the tip 96 in a liquid-tight/fluid-tight manner.", "On the other hand, the proximal end of the inner tube shaft 95 is firmly attached (fixed) to a part in the outer circumferential direction of the intermediate shaft 70 (a side opening formed in a side surface) in a liquid-tight/fluid-tight manner, and a proximal opening of the inner tube shaft 95 is exposed to the outside of the intermediate shaft 70, thereby constituting a proximal opening portion 92.An inside space ranging from the distal end of the inner tube 90 to the proximal opening portion 92 constitutes a guide wire lumen 91.A guide wire is inserted in and passed through the inner tube 90, while a distal opening portion 93 of the tip 96 constituting the inner tube 90 serves as an entrance, whereas the proximal opening portion 92 of the inner shaft 95 constituting the inner tube 90 serves as an exit.", "The proximal opening portion 92 may be provided in the proximal shaft 60 or the distal shaft 80, instead of the intermediate shaft 70, or may be provided at a boundary portion between the intermediate shaft 70 and the distal shaft 80.The materials constituting the distal shaft 80, the inner tube shaft 95, the tip 96 and the intermediate shaft 70 are not particularly limited.", "Examples of the materials which can be preferably used include polymeric materials such as polyolefins (e.g., polyethylene, polypropylene, polybutene, ethylene-propylene copolymer, ethylene-vinyl acetate copolymer, ionomer, or mixtures of two or more of them), crosslinked polyolefins, polyvinyl chloride, polyamides, polyimide elastomers, polyesters, polyester elastomers, polyurethanes, polyurethane elastomers, fluororesins, polyimides, and mixtures thereof.", "The material constituting the proximal shaft 60 is preferably a material which is comparatively high in rigidity.", "Examples of the material which can be preferably used include metals such as Ni-Ti alloys, brass, steel special use stainless (SUS), aluminum, etc.", "and resins such as polyimides, vinyl chloride, polycarbonate, etc.", "The hub 40 is provided with a hub proximal opening portion 41 that communicates with the inflation lumen 23 of the catheter shaft 20 and functions as a port through which the inflation fluid flows in and out.", "The hub 40 is fixed in a liquid-tight/fluid-tight connection with the proximal shaft 60.The anti-kinking tube 50 is disposed outside of the proximal shaft 60, in order to prevent the proximal shaft 60 from kinking near the distal end of the hub 40.The balloon 30 is for pushing open (outwardly expanding) a stenosed part by being inflated.", "At a central portion in the axial direction X of the balloon 30, there is formed a cylindrical portion 31 having a cylindrical shape with a constant outside diameter when inflated.", "On both sides of the cylindrical portion 31 in the axial direction X, there are formed tapered portions 33 at which the outside diameter gradually varies.", "The cylindrical portion 31 and the tapered portions 33 on both sides constitute a region in which the balloon 30 is actually inflated.", "A coating layer 32 containing a drug is formed on the whole part of an outside surface of the cylindrical portion 31.The range of the balloon 30 where the coating layer 32 is formed is not limited only to the cylindrical portion 31 but may include at least part of the tapered portions 33 in addition to the cylindrical portion 31; alternatively, the coating layer 32 may be formed on only part of the cylindrical portion 31.A portion of the balloon 30 on the distal side of the distal-side tapered portion 33 constitutes a distal joint portion 34 (distal joint portion or distal joined region) that is joined, by adhesion or fusion bonding, to an outer circumferential surface of the tip 96 constituting the inner tube 90, in a liquid-tight/fluid-tight manner.", "A portion of the balloon 30 on the proximal side of the proximal-side tapered portion 33 constitutes a proximal joint portion 35 (proximal joined region) that is joined, by adhesion or fusion bonding, to an outer circumferential surface of a distal portion of the distal shaft 80 in a liquid-tight/fluid-tight manner.", "The inside of the balloon 30 communicates with the inflation lumen 23 formed in the catheter shaft 20, and the inflation fluid can flow into the balloon 30 from the proximal side through the inflation lumen 23.The balloon 30 is inflated when the inflation fluid flows into the balloon 30, and is brought into a folded state when the inflation fluid having flowed into the balloon is subsequently discharged from the balloon.", "The part to which a distal portion of the balloon 30 is joined may not necessarily be the tip 96 of the inner tube 90 but may be the inner tube shaft 95.In addition, the inner tube may be composed only of the inner tube shaft, without the tip being provided.", "The balloon 30 preferably has a certain degree of flexibility and a certain degree of hardness such that the balloon 30, upon reaching a blood vessel or tissue or the like, can be inflated and can release the drug from the coating layer 32 provided on its surface.", "Specifically, the balloon 30 is formed from a metal or a resin, and at least the outer surface of the balloon 30 on which to provide the coating layer 32 is preferably formed of a resin.", "Examples of the material which can be used to constitute at least the surface of the balloon 30 include polyolefins such as polyethylene, polypropylene, polybutene, ethylene-propylene copolymer, ethylene-vinyl acetate copolymer, ionomer or mixtures of two or more of them, thermoplastic resins such as flexible polyvinyl chloride resin, polyam ides, polyamide elastomers, polyesters, polyester elastomers, polyurethanes, fluororesins, etc., silicone rubbers, latex rubber, and so on.", "Among these, preferred are polyamides.", "Specifically, at least part of the surface of the inflatable portion of the medical device to be coated with the drug is formed of a polyamide.", "The surface of the inflatable portion formed of a polyamide provides a smooth surface.", "The polyamide is not particularly limited so long as it is a polymer having an amide bond.", "Examples of the polyamide include homopolymers such as polytetramethylene adipamide (nylon 46), polycaprolactam (nylon 6), polyhexamethylene adipamide (nylon 66), polyhexamethylene sebacamide (nylon 610), polyhexamethylene dodecamide (nylon 612), polyundecanolactam (nylon 11), polydodecanolactam (nylon 12), etc., copolymers such as caprolactam/lauryllactam copolymer (nylon 6/12), caprolactam/aminoundecanoic acid copolymer (nylon 6/11), caprolactam/w-aminononanoic acid copolymer (nylon 6/9), caprolactam/hexamethylenediammonium adipate copolymer (nylon 6/66), etc., and aromatic polyamides such as copolymer of adipic acid and metaxylenediamine, copolymer of hexamethylene diamine and m,p-phthalic acid, etc.", "Further, polyamide elastomers which are block copolymers including nylon 6, nylon 66, nylon 11, nylon 12 or the like as hard segment and polyalkylene glycol, polyether, aliphatic polyester or the like as soft segment may also be used as a base material for the medical device according to the present embodiment.", "The above-mentioned polyamides may be used either singly or in a combination of two or more of them.", "The balloon 30 is formed with the coating layer 32 either directly on the outer surface of the balloon or with a pretreatment layer such as a primer layer formed between the outer surface of the balloon and the coating layer 32, depending on a coating method which will be described later.", "Next, the balloon coating apparatus 100 will be described.", "As illustrated in FIG.", "1, the balloon coating apparatus 100 includes a rotation driving section 110 (first rotation driving section) configured to rotate the balloon 30 about the axis X of the balloon 30, a base section 120 configured to support the balloon catheter 10, and a coating section 130 provided with a dispensing tube 134 for dispensing a coating liquid and applying the coating liquid to an outer surface of the balloon 30.Further, the balloon coating apparatus 100 includes a rectilinear moving section 140 configured to move the dispensing tube 134 relative to the balloon 30, a tension section 150 (second rotation driving section) configured to apply a tensile force to the balloon 30, and a control unit 160 configured to control the balloon coating apparatus 100.As shown in FIGS.", "1, 4A and 4B, the rotation driving section 110 includes a driving shaft 111 inserted into a three-way cock 170 attached to the hub proximal opening portion 41 (see FIG.", "2) of the hub 40 of the balloon catheter 10, a first motor 112 for rotating the driving shaft 111, and a first shaft joint 114 interlocking a rotary shaft 115 of the first motor 112 with the driving shaft 111.With the three-way cock 170 attached to the hub 40, it is possible to introduce the inflation fluid into the balloon 30 to inflate the balloon 30, by opening the three-way cock 170, and to maintain the inflated state of the balloon 30 by closing the three-way cock 170.The first motor 112 is fixed to a bed 121.The driving shaft 111 is interlocked to the rotary shaft 115 of the first motor 112 by the first shaft joint 114, and is formed at a distal portion thereof with a male luer taper (projected luer taper) 116 the diameter of which decreases distally.", "The male luer taper 116 can be inserted into a female luer taper (recessed luer taper) 171 formed in the three-way cock 170, to be fitted to the female luer taper 171 with a frictional force.", "The taper ratio of the male luer taper 116 and the female luer taper 171 is prescribed in International Organization for Standardization (ISO) 594 and Japanese Industrial Standards (JIS) (commentary on standards and reference concerning medical devices), and is prescribed to be 6%.", "The range of insertion of the driving shaft 111 is within the range of the three-way cock 170, and the driving shaft 111 can be fitted to and detached from the three-way cock 170 easily, which is highly user friendly.", "The male luer taper 116 of the driving shaft 111 may be fitted to a female luer taper which is formed not in the three-way cock 170 but at the hub proximal opening portion 41 of the hub 40.In this case, the driving shaft 111 is not inserted to the distal side beyond the hub 40.Since the driving shaft 111 is not inserted to the distal side beyond the hub 40, the catheter shaft 20 can bend flexibly, and the driving shaft 111 can be fitted to and detached from the balloon catheter 10 easily, which is highly user friendly.", "The base section 120 includes the bed 121 serving as a base, and a support part 180 fixed to the bed 121 and supporting the catheter shaft 20 such that the catheter shaft 20 is rotatable.", "The base section 120 includes a guide groove part (guide groove) 122 holding the tension section 150 such that the tension section 150 can be moved rectilinearly, and a rack 123 having teeth aligned rectilinearly.", "As shown in FIGS.", "1, 5 and 6, the support part 180 includes a support base 181 formed with a groove portion (groove) 182 in which the catheter shaft 20 is rotatably accommodated, a lid portion (lid) 183 configured to cover a support surface 186 formed with the groove portion 182 of the support base 181, and hinge portions 184 connecting the lid portion 183 to the support base 181 such that the lid portion 183 can be opened and closed in relation to the support base 181.The lid portion 183 is provided with a handle 185 for easy grasping at the times of opening and closing the lid portion 183.The support base 181 is formed to be elongate along the axial direction X such as to be able to support the elongate catheter shaft 20.The groove portion 182 formed in the support surface 186 includes a first groove portion 182A configured to support a part of the catheter shaft 20 that is near the balloon 30, a second groove portion 1826 configured to support a range inclusive of a part of the catheter shaft 20 that is near the proximal opening portion 92, and a third groove portion 182C configured to support a portion of the catheter shaft 20 that is on the proximal side of the proximal opening portion 92.The first groove portion 182A, the second groove portion 1826 and the third groove portion 182C are arranged on an extension line of the driving shaft 111, aligned in this order from the distal side.", "The first groove portion 182A, the second groove portion 182B and the third groove portion 182C may be located with a slight deviation to the vertically lower side from the extension line of the driving shaft 111, taking into account bending of the catheter shaft 20 due to its own weight between the driving shaft 111 and the support base 181.The second groove portion 182B is greater in width and depth than the first groove portion 181A and the third groove portion 182C, such that a part of the catheter shaft 20 near the proximal opening portion 92 that is locally projecting from the surroundings can be restrained from being damaged by friction.", "The groove portion formed in the support base 181 may be constant in width and depth.", "In addition, the groove portion formed in the support base 181 may be constant, or varies from part to part, in only one of width and depth.", "The width and depth of the groove portion 182 (the first groove portion 182A, the second groove portion 182B and the third groove portion 182C) are preferably greater than the outside diameter of the catheter shaft 20 by approximately 1 mm to 5 mm.", "If the width and depth of the groove portion 182 are too small, the catheter shaft 20 is liable to be damaged by friction, and the load on rotation becomes large, making rotation of the balloon 30 unstable; as a result, it may be difficult to form the coating layer 32 in an appropriate amount, and it may be difficult to control, for example, the morphological form of the drug in the coating layer 32.On the other hand, if the width and depth of the groove portion 182 are too large, the catheter shaft 20 moves irregularly within the groove portion 182 upon rotation, making the rotation of the balloon 30 unstable; consequently, it may be difficult to form the coating layer 32 in an appropriate amount, and it may be difficult to control, for example, the morphological form of the drug in the coating layer 32.The shape of the groove portion 182 has a semicircular shape at a bottom surface in cross-section orthogonal to the axial direction X in this embodiment, but this is not restrictive, and the shape may be a V shape or a tetragonal shape, for example.", "The shape of the groove portion 182 is preferably such as to make surface contact with the catheter shaft 20, such that the catheter shaft 20 is not liable to be damaged.", "Therefore, the shape of the groove portion 182 preferably does not have a projecting part, such as a W-shaped part, in cross-section orthogonal to the axial direction X.", "The lid portion 183 is rotatably held on the support base 181 by the hinge portions 184, can cover the support surface 186 to close the groove portion 182, and can be separated from the support surface 186 to expose the groove portion 182.The lid portion 183 functions to maintain the catheter shaft 20, which is rotated in the groove portion 182, within the groove portion 182.The lid portion 183 preferably has a certain degree of weight such that the rotating catheter shaft 20 would not fly out of the groove portion 182, the weight being, for example, not less than 30 g. The lid portion 183 may be provided with a locking mechanism (not shown) for fixing the lid portion 183 to the support base 181.The locking mechanism may be, for example, snap fit.", "The materials constituting the support base 181 and the lid portion 183 are not specifically restricted, and there can be used those materials which have a low coefficient of friction, such as PTFE (polytetrafluoroethylene) and rigid polyethylene.", "As shown in FIG.", "1, the tension section 150 (second rotation driving section) includes a sliding part 151 fitted to the guide groove part 122 of the base section 120, a pinion 152 meshed with the rack 123, a dial 153 for rotating the pinion 152, and a holding part 190 configured to hold the balloon catheter 10.Further, the tension section 150 includes a second motor 154 for rotating the holding part 190, and a second shaft joint 156 interlocking a rotary shaft 155 of the second motor 154 with the holding part 190.The sliding part 151 is slidably fitted to the guide groove part 122 of the base section 120, and slides within the guide groove part 122, thereby moving the second motor 154 rectilinearly.", "The pinion 152 is rotated by rotational operation of the dial 153, and, by meshing with the rack 123, can move the sliding part 151 along the guide groove part 122.With the dial 153 rotated, a tensile force can be exerted on the balloon 30.The tensile force, which is not particularly limited, is preferably 5 N to 15 N, for example.", "If the tensile force is too small, bend of the balloon 30 cannot be straightened.", "If the tensile force is too large, on the other hand, the balloon 30 may be damaged by the tensile force.", "When the tensile force is exerted on the balloon 30, a force acts in such a direction as to disengage the male luer taper 116 of the driving shaft 111 from the female luer taper 171 of the three-way cock 170.Therefore, a fixing strength between the driving shaft 111 and the three-way cock 170 is desirably at such a level as to be able to endure the tensile force exerted, and is, for example, 10 N to 50 N. If the fixing strength between the driving shaft 111 and the three-way cock 170 is too strong, the hub 40 may be damaged when the balloon catheter 10 is detached from the apparatus.", "For instance, in the case of a balloon catheter 10 wherein the balloon 30 is formed of a polyamide resin, the outside diameter of the balloon 30 when inflated is 6 mm and the length of the balloon 30 is 150 mm, it has been confirmed that exertion of a force of 25 N damages the balloon 30.If the fixing strength between the driving shaft 111 and the three-way cock 170 is too weak, on the other hand, exertion of the tensile force on the balloon 30 may cause the driving shaft 111 and the three-way cock 170 to be disengaged from each other.", "Instead of manual rotation of the dial 153, a motor or the like may be provided and controlled.", "As shown in FIGS.", "7 and 8, the holding part 190 includes a collet chuck 191, and a chuck holder 200 for holding the collet chuck 191.The collet chuck 191 is formed therein with slits 195 such that a plurality of (in this embodiment, four) clamping portions 193 having clamping surfaces 194 shaped correspondingly to the shape of an object to be grasped are arranged in the circumferential direction of the collet chuck 191.The collet chuck 191 is formed with a tapered surface 196 at an outer circumferential surface on an end portion side where the clamping portions 193 are formed, and is formed, on the opposite side from the side where the clamping portions 193 are formed, with a interlock portion 197 configured to interlock with the second shaft joint 156.The interlock portion 197 is smaller in outside diameter than the clamping portions 193.Between the clamping portions 193 and the interlock portion 197 is formed a stepped portion 198 where outside diameter is reduced.", "The clamping surfaces 194 are formed of groove-shaped curved surfaces extending along the axis of the distal joint portion 34 between the balloon 30 and the inner tube 90, the joint portion 34 being grasped.", "The clamping surfaces 194 can clamp a portion of the side surface of the distal joint portion 34, such that deformation of the distal joint portion 34 is prevented as securely as possible.", "A scroll chuck, a drill chuck or an independent chuck may be used in place of the collet chuck 191, so long as the distal joint portion 34 can be clamped on a surface basis such that deformation of the distal joint portion 34 is prevented as securely as possible.", "In addition, the number of the clamping portions is not limited to four, so long as the number is not less than two.", "The chuck holder 200 includes a first holder 201 that the interlock portion 197 of the collet chuck 191 penetrates, and a second holder 202 that the clamping portions 193 of the collet chuck 191 contact.", "The first holder 201 is a tube-shaped member that the interlock portion 197 of the collet chuck 191 penetrates.", "The first holder 201 is formed on one end side with an attachment portion 203 configured to make contact with the stepped portion 198 of the collet chuck 191 such that the stepped portion 198 is caught on the attachment portion 203, and is formed with a first screw portion 205 at an outer circumferential surface of the attachment portion 203.The second holder 202 is a tube-shaped member having a second screw portion 206 for screw engagement with the first screw portion 205, and is formed at an inner circumferential surface of the second holder 202 with a tapered push-in surface 204 for contact with the tapered surface 196 of

catheter shaft 20, is accommodated in the second groove portion 1828 formed to be larger than the first groove portion 182A and the third groove portion 182C in width and depth, damage to the proximal opening portion 92 due to friction can be restrained.", "In addition, since the groove portion 182 is covered with the lid portion 183, the catheter shaft 20 can be restrained from flying out of the groove portion 182, and the balloon 30 can be rotated in a stable manner.", "When the balloon catheter 10 is rotated, the balloon 30 may, in some cases, become eccentric due to bending along the axial

good contact of these members is maintained.", "Consequently, variations in the thickness of the coating liquid applied can be restrained, and it becomes relatively easy to control the thickness and

molecular weight of the excipient is smaller than the molecular weight of the water-insoluble drug.", "Therefore, the proportion of the excipient particles per a predetermined area of the substrate is smaller than the proportion of the crystal particles, and, accordingly, the excipient particles do not form a matrix.", "Here, the crystal particles of the water-insoluble drug may be one of the above-mentioned elongate bodies, the excipient particles are present in the state of being by far smaller than the crystal particles of the water-insoluble drug and dispersed between the crystal particles of the water-insoluble drug; accordingly, in some cases, the excipient particles may not be observed in a scanning electron microscope (SEM) image or a laser microphotograph.", "The crystal layer of the hollow elongate body morphological form, when delivered into a living body as a coating layer formed by coating a substrate surface of a medical device with the drug, is low in toxicity and high in stenosis inhibitory effect.", "The present inventors consider that the reason for this lies in that the solubility of the drug having a certain crystal morphology after transfer to tissue and the property for being retained in the tissue have influences on these characteristic properties.", "The water-insoluble drug including the hollow elongate body crystal morphology, upon transfer to the tissue, is reduced in the size of one unit of crystal; therefore, the drug is high in the property for permeation into the tissue.", "In addition, the water-insoluble drug is high in solubility in the tissue.", "The high permeation property and high solubility permit the drug to act effectively, whereby stenosis can be inhibited.", "The drug is considered to be low in toxicity because the drug is less liable to remain as large lumps in the tissue.", "In addition, the layer including the hollow elongate body crystalline morphological form is a morphological form wherein substantially uniform elongate bodies having long axes stand together substantially uniformly and regularly on the substrate surface.", "Therefore, the size (the length in the long axis direction) of the crystals transferred to the tissue is as small as approximately 10 μm.", "For this reason, the drug acts uniformly on the lesion affected area, and its property for permeation into the tissue is enhanced.", "Further, since the crystals transferred to the tissue are small in size, a situation in which an excess amount of the drug would be retained in the lesion affected area for an excess time is obviated.", "For this reason, the drug is considered to be able to show a high stenosis inhibitory effect, without exhibiting toxicity.", "Where the extending direction of the dispensing tube 134 or the ejection direction of the coating liquid is reverse to the rotating direction of the balloon 30, the water-insoluble drug in the coating layer 32 acquires a morphological form including the hollow elongate body crystalline morphological form.", "The principle of this phenomenon may be considered to lie, for example, in that the coating liquid ejected from the ejection end 136 onto the balloon 30 is stimulated by the dispensing tube 134 due to the rotation.", "In addition, in the condition where a part of a side surface on the end portion side of the dispensing tube 134 (a part of the continuous length in the extending direction of the dispensing tube 134) is in contact with the outer surface of the balloon 30, the coating liquid is ejected from the ejection end 136 onto the balloon 30.Consequently, appropriate contact can be realized between the dispensing tube 134 and the balloon 30, such as to give the morphological form wherein the crystals of the water-insoluble drug include a plurality of elongate bodies having independent long axes.", "The coating liquid is ejected from the ejection end 136 onto the balloon 30, in a region in which the balloon 30 is rotated toward the upper side in the vertical direction.", "For this reason, the extending direction of the dispensing tube 134, which extends downward such as to ensure easy ejection of the coating liquid, can be easily set to be reverse to the rotating direction of the balloon 30.If the material constituting the dispensing tube 134 coming into contact with the balloon 30 is polyolefin (fluorine-free polyolefin) such as polyethylene, polypropylene, etc., the dispensing tube 134 is lower in organic solvent resistance but is higher in affinity for organic solvents and smaller in contact angle with organic solvent, as compared to a tube made of fluororesin such as PTFE.", "Accordingly, the coating liquid is less liable to be repelled due to the characteristic properties of the material of the dispensing tube 134 at the ejection end 136 and at the part of contact with the balloon 30.Therefore, coating unevenness is less liable to occur in coating the outer surface of the balloon 30 with the coating liquid, and the uniformity of the coating layer 32 can be controlled with high accuracy.", "Specifically, using a material not so high as fluororesin in organic solvent resistance for the dispensing tube 134, it is possible to lower the possibility of unevenness in coating the outer surface of the balloon 30 with the coating liquid.", "In addition, where the material constituting the dispensing tube 134 is polyolefin such as polyethylene, polypropylene, etc., it is also possible to cause unevenness in coating the outer surface of the balloon 30 with the coating liquid, by controlling at least one of the moving speed of the dispensing tube 134, the ejection rate of the coating liquid, and the rotational speed of the balloon 30.For this reason, by forming the dispensing tube 134 from polyolefin such as polyethylene or polypropylene, it is possible to freely control the level of uniformity of the coating layer 32.If the material constituting the dispensing tube 134 is fluororesin such as PTFE, ETFE, PFA, FEP, etc., affinity for organic solvents is low and contact angle with organic solvent is large.", "Accordingly, the coating liquid is strongly repelled due to the characteristic properties of the material of the dispensing tube 134 at the ejection end 136 and at the contact part with the balloon 30.Therefore, it is possible to easily cause unevenness (nonuniformity) in coating the outer surface of the balloon 30 with the coating liquid.", "Where the unevenness in coating with the coating liquid is heavy, it is possible to increase the amount of the drug actually applied to some parts, while keeping constant the total amount of the drug contained in the coating layer 32 formed on the balloon 30.By this, it is possible to cause the drug to act effectively, without increasing the burden on the living body.", "The unevenness in coating is preferably a regular nonuniformity and is preferably a stripe pattern (spiral linear body) in which linearly coated parts are aligned in the axial direction X of the balloon 30.By applying the coating liquid while rotating the balloon 30 relative to the dispensing tube 134, the coating layer 32 can be easily formed while producing unevenness of coating in a stripe pattern.", "Unevenness of coating is not restricted to the form of a stripe pattern; for example, a state where extremely shaded phases are formed may be adopted.", "In the coating step, it is also possible to control the uniformity of the coating layer 32, by using both a dispensing tube 134 formed of polyolefin and another dispensing tube 134 formed of fluororesin and utilizing the aforementioned different characteristic properties of the resin materials.", "In the case of using both the dispensing tubes 134 having the different characteristic properties, for example, at the time of sequentially coating balloons 30 of a plurality of balloon catheters 10, a control of changing the dispensing tube 134 according to the balloon 30 can be carried out.", "In addition, a control of changing the dispensing tube 134 depending on the part being coated of one balloon 30 can also be performed.", "The drug in the coating on the outer surface of the balloon 30 can assume different morphological forms such as crystalline form, amorphous form, and mixed forms thereof.", "In the case where the drug is of the crystalline form, there exist various morphological forms which differ in crystal structure.", "Further, crystals and amorphous phases may be disposed regularly in the coating layer 32, or may be disposed irregularly in the coating layer 32.With the dispensing tube 134 gradually moved in the axial direction X of the balloon 30 while rotating the balloon 30, the coating layer 32 is formed on the outer surface of the balloon 30 gradually along the axial direction X.", "After the range of the part to be coated of the balloon 30 is entirely formed thereon with the coating layer 32, the rotation driving section 110, the tension section 150, the rectilinear moving section 140 and the coating section 130 are stopped.", "Thereafter, the balloon catheter 10 is dismounted from the balloon coating apparatus 100, and the coating of the balloon 30 is completed.", "As described above, the balloon coating method according to the first embodiment is a balloon coating method for forming a coating layer 32 containing a water-insoluble drug on an outer surface of a balloon 30 of a balloon catheter 10, wherein the method includes: fitting a driving shaft 111 for rotating the balloon catheter 10 to an opening portion of a three-way cock 170 (interlock member) attached to a proximal portion of a hub 40 of the balloon catheter 10 and fixing the driving shaft 111 in situ by a frictional force; and rotating the balloon 30 about the axis X of the balloon 30 by the driving shaft 111 and applying a coating liquid containing the drug to the outer surface of the balloon 30.In the balloon coating method configured as above, since the driving shaft 111 is fitted and fixed to the opening portion formed in the three-way cock 170, the hub 40 is rotated about the center axis of the driving shaft 111, and, therefore, the balloon 30 can be rotated while being prevented as securely as possible from whirling.", "For this reason, the position of the outer surface of the balloon 30 is not liable to fluctuate during rotation, and the coating liquid can be applied to the outer surface of the balloon 30 in an appropriate quantity.", "In addition, since the position of the outer surface of the balloon 30 is not liable to fluctuate during rotation, the contact force in contact of the dispensing tube 134 with the balloon 30 can be easily set to a desirable value, so that, for example, the morphological form of the drug in the coating formed on the balloon 30 can be set appropriately.", "Note that the interlock member is not limited to the three-way cock 170, and may, for example, be a member produced for exclusive use.", "In addition, since the driving shaft 111 is interlocked to the three-way cock 170 (interlock member) by a frictional force, the three-way cock 170 is disengaged from the driving shaft 111 when a predetermined tensile force is exerted thereon.", "Therefore, the three-way cock 170 is disengaged from the driving shaft 111 before an excessive force acts on the balloon 30 to damage the balloon 30; thus, damaging of the balloon 30 can be inhibited.", "According to the balloon coating method described above, in the application of the coating liquid, the coating liquid containing the drug is applied to the outer surface of the balloon 30 while exerting on the balloon 30 a tensile force pulling the balloon 30 in the axial direction X of the balloon 30.As a result, any bend of the balloon 30 is straightened by the tensile force, a rotating force transmitted from the hub 40 capable of stable rotation is stably transmitted to the balloon 30, whereby it can be ensured that the position of the outer surface of the balloon 30 is further less liable to fluctuate during rotation.", "Therefore, the coating liquid can be applied to the outer surface of the balloon 30 in a more appropriate quantity.", "In addition, the contact force in contact of the dispensing tube 134 with the balloon 30 can be easily set to a desirable value.", "Accordingly, for example, the morphological form of the drug in the coating formed on the balloon 30 can be set more appropriately.", "According to the balloon coating method described above, in the fixing of the proximal portion of the hub 40, the driving shaft 111 formed with the male luer taper 116 having a shape according to the female luer taper 171 formed at the opening portion of the three-way cock 170 (interlock member) is fitted and fixed to the female luer taper 171.As a result, it is possible to position the three-way cock 170 relative to the driving shaft 111 accurately and easily, to stabilize the rotation, and to ensure that the position of the outer surface of the balloon 30 is not liable to fluctuate during rotation.", "In addition, by applying male luer tapers 116 prescribed by the standards to the driving shaft 111, a variety of balloon catheters 10 produced adopting female luer tapers 171 prescribed by the standards can be rotated by the driving shaft 111.Because the interlock member is a three-way cock 170, it is possible to interlock the driving shaft 111 to the hub 40 through the three-way cock 170, while ensuring that fluid can be caused to flow into and out of the balloon 30 through the three-way cock 170 by changing over a cock element of the three-way cock 170.Further, the balloon coating method according to the first embodiment is a balloon coating method for forming a coating layer 32 containing a water-insoluble drug on an outer surface of a balloon 30 of a balloon catheter 10, wherein the method includes: inserting a core member 207 into a guide wire lumen 91 penetrating the balloon 30, disposing a proximal portion of the core member 207 on the proximal side of an inflation region of the balloon 30 (a cylindrical portion 31 and tapered portions 33 on both sides thereof), with a distal portion of the core member 207 protruding distally beyond a distal opening portion 93 of the guide wire lumen 91, and fixing by clamping together with the core member 207 a part of the balloon catheter 10 that is on a distal side of the region of inflation of the balloon 30; and moving a dispensing tube 134 for supplying a coating liquid containing the drug relative to the balloon 30 in an axial direction X of the balloon 30, while rotating the balloon 30 about the axis X of the balloon 30, to thereby apply the coating liquid to the outer surface of the balloon 30.According to the balloon coating method configured as above, the distal portion of the core member 207 protrudes distally beyond the distal opening portion 93 of the guide wire lumen 91 and the part of the balloon catheter 10 that is on the distal side of the region of inflation of the balloon 30 is fixed by clamping it together with the core member 207, and, therefore, deformation due to crushing of the balloon catheter 10 is inhibited from occurring at the time of the clamping.", "Further, since the proximal portion of the core member 207 is located on the proximal side of the inflation region of the balloon 30, the shape of the balloon 30 is effectively straightened by the core member 207.Therefore, deformation and damaging of the balloon catheter 10 can be restrained.", "In addition, the position of the outer surface of the balloon 30 is not liable to fluctuate during rotation, and, accordingly, the coating liquid can be applied to the outer surface of the balloon 30 in an appropriate quantity.", "In addition, since the position of the outer surface of the balloon 30 is not liable to fluctuate during rotation, the contact force in contact of the dispensing tube 134 with the balloon 30 can be easily set to a desirable value.", "Consequently, for example, the morphological form of the drug in the coating formed on the balloon 30 can be set appropriately.", "In the balloon coating method as above, the balloon catheter 10 is of a rapid exchange type.", "During the fixing of the balloon catheter 10, the balloon catheter 10 is fixed, with the proximal portion of the core member 207 disposed on the distal side of the proximal opening portion 92 of the guide wire lumen 91 without protruding from the proximal opening portion 92.This helps ensure that the core member 207 does not interfere with surrounding members or the like when the balloon catheter 10 is rotated, and that the position of the outer surface of the balloon 30 is not liable to fluctuate during rotation.", "Therefore, the coating liquid can be applied to the outer surface of the balloon 30 in a more appropriate quantity.", "In addition, the contact force in contact of the dispensing tube 134 with the balloon 30 can be easily set to a desirable value, so that, for example, the morphological form of the drug in the coating formed on the balloon 30 can be set more appropriately.", "According to the balloon coating method as above, the position of the proximal portion of the core member 207 is coincident with the position of the proximal end of the balloon 30 or is on the proximal side of the balloon 30, and the proximal portion of the core member 207 does not protrude from the proximal opening portion 92.This makes it possible to dispose the core member 207 at a position where the balloon 30 is provided, while ensuring that the core member 207 does not protrude from the proximal opening portion 92 and the core member 207 is prevented from interfering with surrounding members or the like during rotation, whereby the rotation of the balloon 30 can be stabilized.", "Therefore, the coating liquid can be applied to the outer surface of the balloon 30 in a more appropriate quantity.", "The contact force in contact of the dispensing tube 134 with the balloon 30 can be easily set to a desirable value, so that, for example, the morphological form of the drug in the coating formed on the balloon 30 can be set more appropriately.", "In the balloon coating method as above, the separated distance of the proximal portion of the core member 207 from the proximal opening portion 92 is up to 50 mm.", "This makes it possible to dispose the core member 207 over a wide as possible range of the guide wire lumen 91, while ensuring that the core member 207 does not protrude from the proximal opening portion 92 and the core member 207 is prevented from interfering with surrounding members or the like during rotation, whereby the rotation of the balloon 30 can be stabilized.", "Therefore, the coating liquid can be applied to the outer surface of the balloon 30 in a more appropriate quantity.", "In addition, the contact force by which the dispensing tube 134 contacts the balloon 30 can be easily set to a desirable value, so that, for example, the morphological form of the drug in the coating formed on the balloon 30 can be set more appropriately.", "In the balloon coating method as above, the value obtained by subtracting the outside diameter of the core member 207 from the inside diameter of the guide wire lumen 91 is greater than 0 mm and not greater than 0.5 mm.", "Therefore, the diameter of the core member 207 is not too large in relation to the inside diameter of the guide wire lumen 91, so that damage to the inner tube 90, in which is formed the guide wire lumen 91, by the core member 207 can be restrained effectively.", "Further, since the diameter of the core member 207 is not too small in relation to the inside diameter of the guide wire lumen 91, deformation of the inner tube 90 can be effectively restrained from occurring when the inner tube 90 is clamped.", "Further, the balloon coating method according to the first embodiment is a balloon coating method for forming a coating layer 2 containing a water-insoluble drug on an outer surface of a balloon 30 of a balloon catheter 10, wherein the method includes: fixing a distal joint portion 34 (connection portion) between an inner tube 90 penetrating the inside of the balloon 30 and the balloon 30 in such a manner as to clamp the distal joint portion 34 by at least two clamping portions 193 each having a groove-shaped curved surface extending along the axis X of the inner tube 90; and moving a dispensing tube 134 for supplying a coating liquid containing the drug relative to the balloon 30 in the axial direction X of the balloon 30, while rotating the balloon 30 about the axis of the balloon 30, to thereby apply the coating liquid to the outer surface of the balloon 30.According to the balloon coating method configured as above, since the distal joint portion 34 constituting a joint between the inner tube 90 and the balloon 30 is fixed in the manner of being clamped by the clamping portions 193 having the groove-shaped curved surfaces, the inner tube 90 and the region of inflation of the balloon 30 are prevented from being damaged, they can be inhibited from becoming eccentric, and the position of the outer surface of the balloon 30 becomes less liable to fluctuate during rotation.", "Therefore, the coating liquid can be applied to the outer surface of the balloon 30 in an appropriate quantity.", "In addition, since the position of the outer surface of the balloon 30 is less liable to fluctuate during rotation, the contact force in contact of the dispensing tube 134 with the balloon 30 can be easily set to a desirable value, so that, for example, the morphological form of the drug in the coating formed on the balloon 30 can be set appropriately.", "In addition, according to the balloon coating method as above, in the application of the coating liquid, the coating liquid containing the drug is applied to the outer surface of the balloon 30 by rotating the balloon 30 while pulling the balloon 30 in the axial direction X of the balloon 30 by clamping portions 193.This ensures that bend of the balloon 30 is straightened by the tensile force, so that the position of the outer surface of the balloon 30 becomes less liable to fluctuate during rotation.", "Therefore, the coating liquid can be applied to the outer surface of the balloon 30 in an appropriate quantity.", "In addition, the contact force in contact of the dispensing tube 134 with the balloon 30 can be easily set to a desirable value, so that, for example, the morphological form of the drug in the coating formed on the balloon 30 can be set more appropriately.", "Although a grasping force by the clamping portions 193 is increased because of the exertion of the tensile force, damaging of the inner tube 90 and the balloon 30 can be restrained because the distal joint portion 34 is grasped by the clamping portions 193 having the groove-shaped curved surfaces.", "In the balloon coating method as above, at least two clamping portions 193 are provided in a collet chuck 191.As a result, the distal joint portion 34 can be fixed by the collet chuck 191 easily and assuredly; further, a tensile force can be effectively exerted on the balloon 30.Further, the balloon coating method according to the first embodiment is a balloon coating method for forming a coating layer 32 containing a water-insoluble drug on an outer surface of a balloon 30 of a balloon catheter 10, wherein the method includes applying the coating liquid containing the drug to the outer surface of the balloon 30 by moving a dispensing tube 134 for supplying the coating liquid relative to the balloon 30 in the axial direction X of the balloon 30, while rotating the balloon 30 about the axis X of the balloon 30 by applying rotating forces to the balloon catheter 10 on both the proximal side and the distal side of a region of inflation of the balloon 30 (a cylindrical portion 31 and tapered portions 33 on both sides thereof) and at the same rotational speed.", "In the balloon coating method configured as above, since the rotating forces are applied to the balloon catheter 10 on both the proximal side and the distal side of the region of inflation of the balloon 30 and at the same rotational speed, the balloon 30 becomes less liable to be twisted or to become eccentric.", "Therefore, the position of the outer surface of the balloon 30 becomes less liable to fluctuate during rotation, so that the coating liquid can be applied to the outer surface of the balloon 30 in an appropriate quantity.", "In addition, since the position of the outer surface of the balloon 30 becomes less liable to fluctuate during rotation, the contact force in contact of the dispensing tube 134 with the balloon 30 can be easily set to a desirable value, so that, for example, the morphological form of the drug in the coating formed on the balloon 30 can be set appropriately.", "According to the balloon coating method as above, in the step of applying the coating liquid, the coating liquid is applied to the outer surface of the balloon 30 by rotating the balloon 30 while pulling the balloon 30 in the axial direction X of the balloon 30.As a result, bending of the balloon catheter 10 is straightened by the tensile force, so that rotating forces can be easily applied to the balloon catheter 10 from both the proximal portion and the distal portion of the balloon catheter 10.In addition, according to the balloon coating method as above, in the application of the coating liquid, the distal joint portion 34 between the inner tube 90 penetrating the inside of the balloon 30 and the balloon 30 is clamped and pulled, whereby a tensile force is exerted in the axial direction X of the balloon 30.As a result, a rotating force can be effectively applied to the balloon catheter 10 through the distal joint portion 34, which is greater in thickness than the surrounding parts, has an outer circumferential surface composed of the flexible material of the balloon 30, and is therefore easy to clamp and apply a rotating force thereto.", "According to the balloon coating method as above, in the step of applying the coating liquid, while the balloon 30 is being rotated about the axis X of the balloon 30, an end portion of the flexible dispensing tube 134 that is formed with an opening portion for ejecting the coating liquid contacts the outer surface of the balloon 30 in such a manner as to face in a direction reverse to the rotating direction of the balloon 30.In this condition, the dispensing tube 134 is moved relative to the balloon 30 in the axial direction X of the balloon 30, and, concurrently with this movement, the coating liquid is ejected from the opening portion, whereby the coating liquid is applied to the outer surface of the balloon 30.As a result, the dispensing tube 134 facing in the direction reverse to the rotating direction of the balloon 30 contacts the balloon 30, whereby a frictional force there is increased, resulting in a condition where the balloon 30 might be liable to be twisted or become eccentric.", "When rotating forces are applied to the balloon catheter 10 on both the proximal side and the distal side and at the same rotational speed, however, the possibility of the balloon 30 being twisted or becoming eccentric can be lowered.", "Accordingly, rotation of the balloon 30 can be stabilized, while promoting crystallization of the water-insoluble drug, by the dispensing tube 134 facing in the direction reverse to the rotating direction of the balloon 30.As a result, the contact force in contact of the dispensing tube 134 with the balloon 30 can be easily set to a desirable value, so that, for example, the morphological form of the drug in the coating formed on the balloon 30 can be set appropriately.", "Further, the balloon coating method according to the first embodiment is a balloon coating method for forming a coating layer 32 containing a water-insoluble drug on an outer surface of an inflatable balloon 30 of a balloon catheter 10 having the balloon 30 at a distal portion of an elongate catheter shaft 20 (shaft), wherein the method includes: accommodating the catheter shaft 20 in a rectilinearly extending groove portion 182 of a support base 181 provided with the groove portion 182, closing the groove portion 182 with a lid portion 183, and supporting the catheter shaft 20 such that the catheter shaft 20 is rotatable within the groove portion 182; and moving a dispensing tube 134 for supplying a coating liquid containing the drug relative to the balloon 30 in the axial direction X of the balloon 30, while rotating the balloon 30 about the axis of the balloon 30, to thereby apply the coating liquid to the outer surface of the balloon 30.In the balloon coating method configured as above, since the catheter shaft 20 (shaft) of the balloon catheter 10 is rotated within the groove portion 182, bending of the catheter shaft 20 is straightened and an accurate rotary motion is promoted, so that the balloon 30 becomes less liable to be twisted or become eccentric.", "Therefore, the position of the outer surface of the balloon 30 becomes less liable to fluctuate during rotation, and the coating liquid can be applied to the outer surface of the balloon 30 in an appropriate quantity.", "In addition, since the position of the outer surface of the balloon 30 becomes less liable to fluctuate during rotation, the contact force in contact of the dispensing tube 134 with the balloon 30 can be easily set to a desirable value, so that, for example, the morphological form of the drug in the coating formed on the balloon 30 can be set appropriately.", "In addition, the catheter shaft 20 can be rotated while straightening its bend, by only accommodating the catheter shaft 20 in the groove portion 182 and closing the groove portion 182 with the lid portion 183, which ensures an easy operation.", "In the balloon coating method as above, the groove portion 182 is located on an extension line of the driving shaft 111 for applying a rotating force to the hub 40 of the balloon catheter 10.This helps ensure that the axis of the driving shaft 111 and the axis of the catheter shaft 20 within the groove portion 182 coincide with each other, so that rotation of the balloon catheter 10 is stabilized, and the balloon 30 becomes less liable to be twisted or become eccentric.", "In the balloon coating method as above, the groove portion 182 varies from part to part in at least one of width and depth.", "This enables those parts of the catheter shaft 20 which differ in shape or diameter to be disposed in those parts of the groove portion 182 which differ in width, so that rotation of the catheter shaft 20 can be stabilized, while restraining abrasion or damaging of the catheter shaft 20.According to the balloon coating method as above, in the application of the coating liquid, the balloon 30 is rotated by applying rotating forces to the balloon catheter 10 on both the proximal side and the distal side and at the same rotational speed.", "As a result, even in a condition where the rotation might become unstable due to a frictional force generated due to the rotation within the groove portion 182, the balloon 30 becomes less liable to be twisted or become eccentric, since the rotating forces are applied to the balloon catheter 10 on both the proximal side and the distal side and at the same rotational speed.", "For this reason, the position of the outer surface of the balloon 30 becomes less liable to fluctuate during rotation, so that the coating liquid can be applied to the outer surface of the balloon 30 in an appropriate quantity.", "In addition, since the position of the outer surface of the balloon 30 becomes less liable to fluctuate during rotation, the contact force in contact of the dispensing tube 134 with the balloon 30 can be easily set to a desirable value, so that, for example, the morphological form of the drug in the coating formed on the balloon 30 can be set appropriately.", "Because the coating liquid is ejected by putting the dispensing tube 134 into contact with the outer surface of the balloon 30 in such a manner that the ejection end 136 faces in the direction reverse to the rotating direction of the balloon 30, the water-insoluble drug in the coating layer 32 formed on the outer surface of the balloon 30 can be set into a morphological form wherein the crystals of the drug include a plurality of elongate bodies having independent long axes.", "In addition, in the balloon coating method as above, the coating liquid is ejected while the dispensing tube 134 is in contact with the outer surface of the balloon 30 in such a manner that the ejection end 136 faces in the direction reverse to the rotating direction of the balloon 30, whereby an appropriate contact is realized between the dispensing tube 134 and the balloon 30, and, for example, the morphological form and the size of the drug contained in the coating layer 32 can be set more freely.", "Second Embodiment A balloon coating method according to a second embodiment of the present disclosure includes rotating a balloon catheter 10 while holding the balloon catheter 10 on a support part rotatable together with the balloon catheter 10, thereby to form a coating layer 32

221.The support part 230 includes a support base 231 for holding the balloon catheter 10, and a lid portion 250 configured to clamp the balloon catheter 10 together with the support base 231.Further, the support part 230 includes hinge portions 251 configured to interlock the lid portion 250 such that the lid portion 250 can be opened and closed relative to the bed 121, and a support shaft 260 inserted in a three-way cock 170 attached to the balloon catheter 10.The support base 231 includes a support base proximal portion 232 penetrating the first motor 221, a support base distal portion 233 to which the lid portion 250 is interlocked, and a support base central portion 234 formed between the support base proximal portion 232 and the support base distal portion 233.The support base proximal portion 232 is a part configured to support a proximal portion of the balloon catheter 10, and penetrates the first motor 221, with the support shaft 260 being fixed on the proximal side of the first motor 221.The support shaft 260 is inserted in the three-way cock 170 attached to the balloon catheter 10, and fixes a proximal portion of the balloon catheter 10.With the three-way cock 170 attached to a hub 40, an inflation fluid can flow into the balloon 30 to inflate the balloon 30, by opening the three-way cock 170, and the inflated state of the balloon 30 can be maintained, by closing the three-way cock 170.The support base distal portion 233 is a part configured to support a distal portion of the catheter shaft 20, and is located on the distal side of the bearing section 240, with the lid portion 250 turnably interlocked by the hinge portions 251.The support base distal portion 233 has a support surface 235 formed of a flexible material for clamping the catheter shaft 20 between itself and the lid portion 250.The support surface 235 is formed with a groove portion 236 in which part of the catheter shaft 20 is accommodated such that the catheter shaft 20 can be

or materials constituting the support surface 235 and the pressing surface 252 include expanded polyurethane and expanded polyethylene.", "The side surface of the support base distal portion 233 includes a recess 237 configured to interlock with a locking mechanism 253 provided on the lid portion 250 for fixing the lid portion 250 to the support base distal portion 233.The locking mechanism 253 is, for example, snap fit.", "The support base central portion 234 is formed with the support surface 235 for supporting the catheter shaft 20, penetrates the bearing section 240, and is rotatably supported by the bearing section 240.The width and depth of the groove portion 236 are preferably smaller than the outside diameter of the catheter shaft 20 by approximately 0.5 mm to 3.5 mm, such that the catheter shaft 20 can be clamped between the groove portion 236 and the lid portion 250.The shape of the groove portion 236 in a section orthogonal to the X-direction has a semicircular bottom surface in this embodiment, this is not restrictive; for example, the shape may be a V shape or a tetragonal shape.", "The shape of the groove portion 236 is preferably such a shape as to make surface contact with the catheter shaft 20, such that the catheter shaft 20 is not liable to be damaged.", "Therefore, the shape of the groove portion 236 preferably does not have a projecting part, such as a W-shaped part, in section orthogonal to the X-direction.", "The groove portion 236 need not be provided.", "The lid portion 250 is turnably held on the support base distal portion 233 by the hinge portions 251, can cover the support surface 235 to close the groove portion 236, and can be separated from the support surface 235 to expose the groove portion 236.The lid portion 250 is formed with the pressing surface 252 for clamping the catheter shaft 20 against the support surface 235.The balloon catheter 10 has a core member 207 disposed within a guide wire lumen 91.The core member 207 has its distal portion protruding distally beyond a distal opening portion 93 of the guide wire lumen 91, and has its proximal portion located on the proximal side of a position of being clamped by the support surface 235 and the pressing surface 252.The length of protrusion of the core member 207 from the distal opening portion 93 is not particularly limited.", "For restraining the balloon catheter 10 from being crushed when clamped by a collet chuck 191, however, the protrusion length is preferably such a length as to be able to protrude assuredly, and is, for example, 2 mm to 50 mm.", "Since the distal portion of the core member 207 protrudes distally beyond the distal opening portion 93 of the guide wire lumen 91 and the proximal portion of the core member 207 is located on the proximal side of the balloon 30, the core member 207 is present on the inside of the part to be clamped by the clamping portions 193, whereby the balloon catheter 10 can be restrained from deformation due to crushing.", "Since the proximal portion of the core member 207 is located on the proximal side of the position of being clamped by the support base 231 having the support surface 235 and the lid portion 250 having the pressing surface 252, the core member 207 is present on the inside of the part to be clamped by the support surface 235 and the pressing surface 252, so that the balloon catheter 10 is restrained from deformation due to crushing.", "The distal portion of the support shaft 260 is formed with a male luer taper 261 where its diameter decreases distally.", "The male luer taper 261, by being inserted into a female luer taper 171 formed in the three-way cock 170, can be fitted to the female luer taper 171 by a frictional force.", "The taper ratio of the male luer taper 261 and the female luer taper 171 is prescribed in ISO 594 and JIS (commentary on standards and reference concerning medical devices), and is prescribed to be 6%.", "The range of insertion of the support shaft 260 is within the range of the three-way cock 170.Therefore, the support shaft 260 can be fitted to and detached from the three-way cock 170 easily, which ensures enhanced usability.", "The male luer taper 261 of the support shaft 260 may be inserted into and fitted to the female luer taper 171 formed at a hub proximal opening portion 41 of the hub 40, instead of the three-way cock 170.The support shaft 260 is not inserted distally beyond the hub 40.This permits the support shaft 260 to be fitted to and detached from the hub 40 easily, which ensures enhanced usability.", "The control unit 160 is composed, for example, of a computer, and generally controls the rotation driving section 220, the rectilinear moving section 140, the tension section 150 and the coating section 130.The control unit 160 can cause the first motor 221 of the rotation driving section 220 and the second motor 154 of the tension section 150 to rotate synchronously at the same rotational speed.", "In addition, the control unit 160 can generally control the rotational speed of the balloon 30, initial positioning of the dispensing tube 134 relative to the balloon 30, the moving speed of the dispensing tube 134 in the axial direction X relative to the balloon 30, the ejection rate of the drug from the dispensing tube 134, and the like.", "Now, a balloon coating method for forming a coating layer 32 containing a water-insoluble drug on a surface of a balloon 30 by use of the balloon coating apparatus 210 will be described below.", "First, the three-way cock 170 is interlocked to the hub proximal opening portion 41 of the hub 40 of the balloon catheter 10, the three-way cock 170 is opened, and an inflation fluid is introduced into the balloon 30 by use of a syringe or the like to inflate the balloon 30, after which the three-way cock 170 is closed, to thereby maintain the inflated state of the balloon 30.The coating layer 32 can also be formed on the surface of the balloon 30 without inflating the balloon 30, and, in that case, it is unnecessary to supply an inflation fluid into the balloon 30.Next, the lid portion 250 interlocked to the support base 231 is opened, the catheter shaft 20 is accommodated in the groove portion 236, and the lid portion 250 is closed, such as to maintain a closed state by the locking mechanism 253.As a result, the catheter shaft 20 is clamped and fixed between the support surface 235 and the pressing surface 252, while the support surface 235 and the pressing surface 252 which can be elastically deformed are deformed flexibly.", "In this instance, deformation of the catheter shaft 20 can be restrained, since the core member 207 is inserted over the range of that part of the catheter shaft 20 which is clamped between the support surface 235 and the pressing surface 252.Next, the male luer taper 261 of the support shaft 260 is inserted into and interlocked to the female luer taper 171 of the three-way cock 170.By this, the hub 40 can be stably held by the support base 231 during rotation.", "In addition, the catheter shaft 20 can also be fixed to the support base proximal portion 232 by a linear member 262, such as rubber band or wire.", "Subsequently, a distal joint portion 34 of the balloon catheter 10 is clamped by the clamping portions 193 of the collet chuck 191.As a result, a rotating force can be applied to a distal portion of the balloon catheter 10 from the second motor 154.The order in which the balloon catheter 10 is disposed on the support shaft 260, the collet chuck 191 and the support base 231 is not particularly restricted.", "Next, a dial 153 is rotated to move the second motor 154 and the collet chuck 191 distally, whereon a tensile force acts on the balloon catheter 10, whereby bending of the balloon 30 is straightened.", "In this instance, since the catheter shaft 20 is clamped between the support surface 235 and the pressing surface 252, the tensile force does not act on the proximal side of the part being clamped.", "Subsequently, a driving portion 144 is operated, to position the dispensing tube 134 relative to the balloon 30.The dispensing tube 134 is brought closer to an outer surface of the balloon 30, and is bent by being pressed against the balloon 30 when making contact with the balloon 30.In this instance, a side surface on an end portion side of the dispensing tube 134 is configured to contact the outer surface of the balloon 30, by appropriately disposing the relevant components.", "Next, a coating liquid is supplied to the dispensing tube 134 while controlling the liquid feed quantity by a liquid feed pump 132, and the balloon catheter 10 is rotated together with the support base 231 by the first motor 221 and the second motor 154.Then, a movable base 141 is moved, to gradually move the dispensing tube 134 proximally along the X-direction.", "Since the dispensing tube 134 is moved relative to the balloon 30, the coating liquid ejected from an ejection end 136 of the dispensing tube 134 is applied to the outer surface of the balloon 30 while drawing a spiral.", "That is, the coating liquid is applied to the outer surface of the balloon 30 in a spiral manner.", "Since the balloon catheter 10 is clamped between the pressing surface 252 and the support surface 235, the part on the proximal side of the position of the part being clamped does not influence the rotation of the balloon 30.Therefore, stable rotation of the balloon 30 can be realized without strict restriction of bend, eccentricity or the like on the proximal side of the position where the balloon catheter 10 is clamped between the pressing surface 252 and the support surface 235.Consequently, unevenness of the thickness of the coating liquid applied can be restrained, and it becomes easy to control the thickness and morphological form of the coating layer 32.Thereafter, the solvent contained in the coating liquid applied to the surface of the balloon 30 is volatilized, resulting in the formation of the coating layer 32 containing the water-insoluble drug on the surface of the balloon 30.Since the extending direction of the dispensing tube 134 toward the ejection end 136 (the ejection direction) is reverse to the rotating direction of the balloon 30, the water-insoluble drug in the coating layer 32 formed on the outer surface of the balloon 30 is formed to include a morphological form wherein the crystals include a plurality of elongate bodies having independent long axes.", "The drug in the coating formed on the outer surface of the balloon 30 can assume different morphological forms such as crystalline form, amorphous form and mixed forms thereof.", "Even where the drug assumes a crystalline form, there exist various morphological forms which differ in crystal structure.", "Further, crystals and amorphous phases may be disposed regularly in the coating layer 32, or may be disposed irregularly in the coating layer 32.By moving the dispensing tube 134 gradually in the axial direction X while rotating the balloon 30, the coating layer 32 is formed on the outer surface of the balloon 30 gradually along the axial direction X.", "After the range of the part to be coated of the balloon 30 is entirely coated with the coating layer 32, the rotation driving section 220, the rectilinear moving section 140, the tension section 150 and the coating section 130 are stopped.", "Thereafter, the balloon catheter 10 is dismounted from the balloon coating apparatus 210, and the coating of the balloon 30 is completed.", "As aforementioned, the balloon coating method according to the second embodiment is a balloon coating method for forming a coating layer 32 containing a water-insoluble drug on an outer surface of an inflatable balloon 30 of a balloon catheter 10 having the balloon 30 provided at a distal portion of an elongate catheter shaft 20 (shaft), wherein the method includes: holding the catheter shaft 20 on a support part 230 rotatable about the axis X of the balloon 30; and moving a dispensing tube 134 for supplying the coating liquid containing the drug relative to the balloon 30 in the axial direction X of the balloon 30, while rotating the balloon 30 together with a support base 231, thereby to apply the coating liquid to the outer surface of the balloon 30.In the balloon coating method configured as above, the balloon 30 is rotated in a state wherein the catheter shaft 20 is held on the rotatable support part 230; therefore, bending of the catheter shaft 20 and the like are not liable to influence the rotation of the balloon 30, so that the balloon 30 is not liable to be twisted or become eccentric.", "For this reason, the position of the outer surface of the balloon 30 is not liable to fluctuate during rotation, so that the coating liquid can be applied to the outer surface of the balloon 30 in an appropriate quantity.", "In addition, since the position of the outer surface of the balloon 30 is not liable to fluctuate during rotation, the contact force in contact of the dispensing tube 134 with the balloon 30 can be easily set to a desirable value, so that, for example, the morphological form of the drug in the coating formed on the balloon 30 can be set appropriately.", "According to the balloon coating method as above, the support part 230 includes the support base 231 formed with the rectilinear groove portion 236 capable of accommodating at least part of the catheter shaft 20 (shaft), and the lid portion 250 capable of covering the lid portion 236, and, during the holding of the catheter shaft 20, the catheter shaft 20 is accommodated in the groove portion 236 and the groove portion 236 is covered with the lid portion 250, to thereby hold the catheter shaft 20 on the support part 230.As a result, the catheter shaft 20 can be held easily and assuredly in such a manner as not to slip off from the groove portion 236.According to the balloon coating method as above, during the holding of the catheter shaft 20, the catheter shaft 20 is clamped by the support base 231 and the lid portion 250.Therefore, the catheter shaft 20 can be firmly held on the support part 230, rotation of the balloon 30 is stabilized, and the balloon 30 becomes less liable to be twisted or become eccentric.", "According to the balloon coating method as above, during the holding of the catheter shaft 20, the catheter shaft 20 is held by the support part 230, with the core member 207 inserted in the catheter shaft 20.This ensures that even when the catheter shaft 20 is held by the support part 230, deformation of the catheter shaft 20 can be restrained.", "According to the balloon coating method as above, while applying the coating liquid, the balloon catheter 10 is rotatably supported by the bearing section 240, which is provided on the distal side of the rotation driving section 220 for applying a rotating force to the support part 230, while rotating the balloon catheter 10 by the rotation driving section 220.This results in that the rotation of the support part 230, which extends distally from the rotation driving section 220, is stabilized.", "Therefore, the rotation of the balloon 30 is stabilized, so that the balloon 30 becomes less liable to be twisted or get eccentric.", "The present disclosure is not limited only to the aforementioned embodiments, and various modifications can be made by those skilled in the art within the scope of the technical thought of the present disclosure.", "For example, while the coating liquid is applied to the balloon 30 from the distal side toward the proximal side of the balloon 30 in the aforementioned first and second embodiments, the coating liquid may be applied from the proximal side toward the distal side.", "In addition, while the dispensing tube 134 extends downward along the vertical direction to contact the balloon 30 in the aforementioned first and second embodiments, the extending direction of the dispensing tube 134 is not specifically restricted.", "For instance, the extending direction may be inclined against the vertical direction, or the dispensing tube 134 may extend sideways or upward.", "While the balloon catheter 10 whose balloon 30 is to be coated is a rapid exchange type balloon catheter in the balloon coating methods according to the aforementioned embodiments, a balloon of an over-the-wire type balloon catheter having a guide wire lumen from a hub to a distal portion may be coated.", "Further, as in a modification of the first embodiment that is illustrated in FIG.", "15, there may be provided a plurality of (in the example shown in FIG.", "15, two) support parts 270 by which the catheter shaft 20 is rotatably supported.", "The support parts 270 may be arbitrarily movable along the axis X of the balloon 30, or along the extending direction of groove portions (not shown) provided in the support parts 270.The plurality of support parts 270 are aligned along the extending direction of the groove portions (not shown) provided in the support parts 270.With the catheter shaft 20 thus supported by the plurality of support parts 270, the rotation of the elongate catheter shaft 20 can be stabilized, while reducing the friction between each support part 270 and the catheter shaft 20 and thereby restraining abrasion or damaging of the catheter shaft 20.In addition, since the support parts 270 are movable, the support parts 270 can be moved prior to the step of supporting the catheter shaft 20 by the support parts 270.As a result, the catheter shaft 20 can be supported at desirable positions, whereby rotation of the balloon catheter 10 can be stabilized.", "Each support base may be provided with a plurality of lid portions.", "Having described several embodiments of the present disclosure which represent examples of the balloon coating method and balloon rotating method disclosed here, it is to

is changed from the reset potential to the signal potential after the charge accumulation.", "When selection pulses are applied to the select transistors 305 through the decoder lines 308, the variation in the signal potential of each floating diffusion FD is transmitted to the output line 309 through the corresponding amplifier transistor 304 and select transistor 305.Based on such a

embodiment, as shown in FIG.", "3, the reset line 306 and TX line 307 are shared by the 16 pixels forming the unit group 131.That is, reset pulses and transfer pulses are simultaneously applied to all the 16 pixels.", "Accordingly, all the pixels forming the unit group 131 start to accumulate charge at the same timing and end the charge accumulation at the same timing.", "Note that selection pulses are sequentially applied to the select transistors 305 and therefore pixel signals corresponding to the accumulated charge are selectively outputted to the output line 309.Different reset lines 306,

controlled for each unit group 131.In other words, it is possible to cause the unit groups 131 to output pixel signals based on different charge accumulation times.", "More specifically, by causing another unit group 131 to accumulate charge several times and to output pixel signals each time while one unit group 131 is caused to accumulate charge once, it is possible to cause the unit groups 131 to output moving image frames at different frame rates.", "FIG.", "4 is a block diagram showing the functional configuration of the image sensor 100.An analog multiplexer 411 sequentially selects

formed along with the PDs 104 in the image-capture chip 113.The analog pixel signals outputted through the multiplexer 411 are amplified by an amplifier 412 which is formed in the signal processing chip 111.The pixel signals amplified by the amplifier 412 are subjected to correlated double sampling (CDS) and analog-to-digital (A/D) conversion by a signal processing circuit 413 which is formed in the signal processing chip 111 and configured to perform CDS and A/D conversion.", "Since the pixel signals are subjected to CDS by the signal processing circuit 413, the noise in the pixel signals is reduced.", "The A/D-converted pixel signals are passed to a demultiplexer 414 and then stored in corresponding pixel memories 415.The demultiplexer 414 and pixel memories 415 are formed in the memory

sequentially refer to and process the values in the pixel memories 415 corresponding to the respective unit groups 131.As described above, the output lines 309 are disposed in a manner corresponding to the respective unit groups 131.In the image sensor 100, the image-capture chip 113, signal processing chip 111, and memory chip 112 are stacked.", "Accordingly, by using, as the output lines 309,

is represented by an ISO sensitivity value.", "When the gain is increased, the ISO sensitivity is increased as well.", "For example, when the gain is doubled, the electrical signal (pixel signal) is doubled as well.", "Thus, appropriate brightness is obtained even when the amount of incident light is halved.", "However, increasing the gain amplifies noise included in the electric signal, thereby increasing noise.", "The thinning-out rate refers to the ratio of the number of pixels from which pixel signals are not read to the total number of pixels in a predetermined region.", "For example, a thinning-out rate of a predetermined region of 0 means that pixel signals are read from all pixels in the predetermined region.", "A thinning-out rate of a predetermined region of 0.5 means that pixel signals are read from half the pixels in the predetermined region.", "Specifically, where a unit group 131 is a Bayer array, one Bayer array unit from which pixel signals are read and one Bayer array

horizontally adjacent pixels, there is obtained an effect similar to that obtained by thinning out the pixels at a predetermined thinning-out rate and reading pixel signals from the resulting pixels.", "In the summation process, an average value may be calculated by dividing the sum of the pixel signals by the row number or column number obtained by the arithmetic circuit 416.The digitized bit number refers to the number of bits of a digital signal converted from an analog signal by the signal processing circuit 413.As the number of bits of a digital signal is increased, luminance, color change, or the like is represented in more detail.", "In the present embodiment, the accumulation conditions refer to conditions on the accumulation of charge in the image sensor

buttons (i.e., image-capture conditions).", "Thus, the user can be urged to operate the button having higher priority.", "In the example described above, the control unit 71 changes the arrangement and appearance (size) of the buttons on the basis of whether a subject in a region is a moving subject.", "However, other configurations may be employed.", "For example, the system control unit 70 instructs the image processing unit 30 to detect the brightness of the image portion in the region.", "The image processing unit 30 then detects the brightness of the image portion in the region on the basis of a corresponding live view image portion.", "The image processing unit 30 then outputs the detection result along with the image data to the system control unit 70.The control unit 71 then determines whether the brightness of the image portion in the region selected by the selection unit 72 falls within a predetermined range, on the basis of the detection result from the image processing unit 30.If not so, the control unit 71 displays the ISO sensitivity button image 522, which is a button for setting the ISO sensitivity, in the second highest place.", "At this time, the control unit 71 displays the ISO sensitivity button image 522 in such a manner that the ISO sensitivity button is larger than the other buttons.", "By changing the ISO sensitivity, the dark part of the live view image is brightened, and the bright part thereof is darkened.", "If the brightness in the region does not fall within the predetermined range, that is, if the image portion in the region is too bright or too dark, it is possible to bring the exposure close to the optimum exposure by changing the ISO sensitivity.", "Accordingly, if the brightness of the image portion in the region does not fall within the predetermined range, the control unit 71 determines that the ISO sensitivity has higher priority than the other image-capture conditions.", "The control unit 71 then moves the position of the ISO sensitivity button image 522 upward, as well as displays the ISO sensitivity button image 522 as a larger button.", "Thus, the button having higher priority is placed in a position in which the user can easily operate the button, thereby increasing the usability.", "Further, the button (i.e., image-capture condition) having higher priority becomes more conspicuous than the other buttons (i.e., image-capture conditions).", "Thus, the user can be urged to operate the button having higher priority.", "Methods for displaying a button having higher priority conspicuously include the enlargement of the button, as well as change of the button color and blinking of the button.", "A button having higher priority may be made conspicuous by displaying multiple image-capture condition values on a side of the button before the user presses the button.", "Only the arrangement of the buttons may be changed, or only the appearance of the buttons may be changed.", "The arrangement and appearance of the buttons may also be changed according to the order in which the user operates the buttons.", "For example, assume that the user presses the selection button image 521, then selects a display region, then presses the imaging mode button image 525, selects manual mode as the imaging mode, and then makes changes to image-capture conditions of each display region.", "In this case, the control unit 71 places the selection button image 521 in the highest position, as well as enlarges it.", "The control unit 71 then places the imaging mode button image 525 in the highest position, as well as enlarges it.", "Then, the control unit 71 places one of the ISO sensitivity button image 522, shutter speed button image 523, and picture control button image 524 in the highest place and enlarges it in accordance with the subject (image) in each display region.", "By changing the arrangement and appearance of the buttons in accordance with the order in which the user operates the buttons, as described above, user convenience is improved.", "Eighth Embodiment Generally, causing the strobe to emit light at the same time that the shutter curtain fully opens is called first curtain synchronization.", "On the other hand, causing the strobe to emit light immediately before the shutter curtain starts to close is called second curtain synchronization.", "In the eighth embodiment, a setting unit 73 sets a slow shutter speed (e.g., ½ s) for the first and second image-capture regions.", "The system control unit 70 also causes the strobe 90 to emit light immediately before charge accumulation ends in the first image-capture region.", "That is, images are captured in the first image-capture region using second curtain synchronization.", "The system control unit 70 also causes the strobe 90 to emit light at the same time that charge accumulation starts in the second image-capture region.", "That is, images are captured in the second image-capture region using first curtain synchronization.", "FIG.", "24 is a timing chart showing the timing of light emission of the strobe 90 and the timing of charge accumulation according to the eighth embodiment.", "As shown in FIG.", "24, the setting unit 73 accumulates charge in the first image-capture region over a period from timing t1, preceding timing t2 when the strobe 90 starts to emit light, to timing t3 when the amount of light emitted by the strobe 90 is lost.", "The setting unit 73 also accumulates charge in the second image-capture region over a period from timing t2 when the strobe 90 starts to emit light to timing t4, following the timing t3 when the amount of light emitted by the strobe 90 is lost.", "The control unit 71 then displays, in the first display region 511, a first image based on image data generated in the first image-capture region and displays, in the second display region 512, a second image based on image data generated in the second image-capture region.", "Thus, the user can previously check the difference between the first image captured using second curtain synchronization and the second image captured using first curtain synchronization.", "When first curtain synchronization is used, for example, the afterimage and light trace of an automobile and the light thereof, which are the subjects, are left in front of the automobile.", "Thus, there is obtained an image as if the automobile were moving backward though it were moving forward.", "On the other hand, when second curtain synchronization is used, there is obtained an image where the afterimage and light trace of an automobile and the light thereof appear behind the automobile naturally.", "Ninth Embodiment A ninth embodiment provides a configuration where the digital camera 1

forms.", "Referring to the Figures wherein like numerals indicate like elements, there is depicted in FIG.", "1 an isometric exploded view of an exemplary embodiment.", "Exemplary merchandise system 10 includes a product dispensing tray 12 in which is mounted an exemplary trackless pusher mechanism 14.As described in more detail below, the pusher mechanism 14 will fit in the tray 12 and will slide along the surface of the tray without the use of tracks, rails, or guides typically used to hold a conventional pusher mechanism to the tray or floor of the tray.", "The pusher mechanism defines a pusher paddle and a pusher floor that extends forward of the pusher paddle.", "A coiled spring may extend across the pusher floor and operatively connect to the tray at a forward position on the tray.", "In one aspect of the invention, product to be merchandised may be placed in the tray in front of the pusher paddle and may sit on the pusher floor as well as the coiled spring.", "With this configuration, the weight of the product will prevent the pusher paddle from tipping to ensure proper pushing of the product.", "In addition, the problems associated with debris or sticky materials hindering the effectiveness of known pusher systems that use tracks, rails or guides have been eliminated.", "Other aspects, embodiments and features of the invention and its teachings are set forth in more detail below.", "The exemplary tray 12 may define a surface 16 and one or more dividing panels or dividers 18 to separate the tray into numerous rows for placement of product.", "In an alternative aspect, the tray 12 may be a shelf or any other surface on which products may be placed for merchandising.", "The surface 16 may be a solid surface or a surface defining a plurality of spaced-apart apertures 20 separated by a plurality of support ribs 22.The apertures 20 and ribs 22 provide a surface that permits the slidable movement of product placed on this surface and also permits liquids and dirt to pass through the apertures 20 so that they do not collect on the surface 16.The surface 16 may be made of any suitable material that permits the slidable movement of product on the surface 16.Other surface or floor configurations are known and may be used with the principles of the invention.", "As depicted in FIGS.", "9 and 10, the surface 16 may define a rounded end portion 24 that includes a notch or cut-out portion 26.The end portion 24 may be rounded to match the shape of the product that is placed on the tray.", "For example, the depicted end portion 24

embodiment depicted in FIGS.", "11-15, the retaining wall 100 may be attached to the surface of the tray and not connect to the dividers.", "In this embodiment, the retaining wall 100 may form an opening 102 defined by an upper member 104, opposing, curved side walls 106 that further define an angled edge 108, and a floor member 110.The side walls 106 may also be straight and not curved depending on the system.", "The end of the coiled spring may also snap-fit into the floor 110 or otherwise attached to the tray using any of the techniques described herein.", "One of skill in the art will readily appreciate that there are numerous shapes and configurations possible for the product-retaining member 44 and that the depicted configurations are merely exemplary embodiments of these numerous configurations.", "Referring back to FIG.", "1, the exemplary trackless pusher mechanism 14 defines a pusher paddle 50 and a pusher floor 52.The pusher paddle 50 and pusher floor 52 may be formed as a single, unitary structure or may be separate structures that are joined together using known techniques.", "In addition, the pusher paddle 50 and pusher floor 52 may be made of any known suitable plastic or metal material.", "The pusher paddle and pusher floor may be reinforced using any known reinforcing techniques.", "In one aspect, the pusher paddle 50 forms a curved-shape pusher surface or face 54 that is configured to match the shape of the product to be merchandised, such as plastic bottles or cans containing a beverage, as depicted in FIGS.", "3-5.The curve-shaped pusher surface 54 permits the pusher to remain centrally aligned with the last product in the tray.", "This configuration reduces friction and drag between the pusher and the divider walls.", "In an alternative aspect, the pusher surface or face may be a flat surface.", "In yet another aspect, the flat pusher surface may be accompanied by a curved shaped rib that is positioned near or on the top of the pusher paddle and that may be used to center and align product in the tray, in a manner similar to the curve-shaped pusher surface 54 depicted in FIG.", "1.The curve shaped rib may define other shapes and configurations that permit cylindrical or similar shaped products to be properly pushed in the tray.", "Advertisement, product identification or other product information may be placed on the pusher surface 54.Positioned behind the pusher surface or face 54 may be one or more support members 58, such as ribs, walls, or gussets.", "The support members 58 are configured to support the pusher surface 54 and further connect the pusher paddle 50 to the pusher floor 52.As can be seen in FIG.", "5, positioned between the support members 58 is the coiled spring 30, and more specifically the coiled end 57 that is used to urge the pusher paddle 50 forward and along the tray 12, as understood in the art.", "Any technique used to operatively connect the coiled spring to the pusher paddle 50 may be used with the invention.", "As shown in FIG.", "1, the pusher floor 52 may be positioned below the pusher paddle 50 and may extend forward of the pusher surface 54 of the pusher paddle.",

(e.g., epidural needle, bone biopsy device, spinal needle, regional block needle, catheter introducer needle, etc.)", "having a penetrating member (e.g., an introducer needle, Tuohy needle, pencil point tipped needle, trocar needle (e.g., JAMSHIDI® biopsy needle), etc.", "), at a distal end, for use in procedures, (e.g., vascular entry and catheterization, single shot or continuous epidurals, spinal access, regional blocks, or bone biopsy, etc.", "), wherein the medical device comprises at least one driving actuator, (e.g., a piezoelectric, voice coil, solenoid, pneumatic, fluidic or any oscillatory or translational actuator etc.)", "attached to the penetrating member (e.g., at a proximal end of the penetrating member), and wherein the driving actuator translates the penetrating member, causing it to reciprocate at small displacements, thereby reducing the force required to penetrate through tissues.", "Additionally, the invention comprises a means for providing feedback, either visually, audibly, or by tactile response, using a variety of detection mechanisms (such as, but not limited to, electrical, magnetic, pressure, capacitive, inductive, etc.", "means), to indicate successful penetration of various tissues, or of voids within the body such as the epidural space so that the clinician knows when to stop as well as to limit power to the driving mechanism.", "Actuator technologies that rely on conventional, single or stacked piezoelectric material assemblies for actuation are hindered by the maximum strain limit of the piezoelectric materials themselves.", "Because the maximum strain limit of conventional piezoelectric materials is about 0.1% for polycrystalline piezoelectric materials, such as lead zirconate titanate (PZT) polycrystalline (also referred to as ceramic) materials and 0.5% for single crystal piezoelectric materials, it would require a large stack of cells to approach useful displacement or actuation of, for example, a handheld medical device usable for processes penetrating through tissues.", "However, using a large stack of cells to actuate components of a handpiece would also require that the tool size be increased beyond usable biometric design for handheld instruments.", "Flextensional actuator assembly designs have been developed which provide amplification in piezoelectric material stack strain displacement.", "The flextensional designs comprise a piezoelectric material driving cell disposed within a frame, platen, endcaps or housing.", "The geometry of the frame, platten, endcaps or housing provides amplification of the axial or longitudinal motions of the driver cell to obtain a larger displacement of the flextensional assembly in a particular direction.", "Essentially, the flextensional actuator assembly more efficiently converts strain in one direction into movement (or force) in a second direction.", "Flextensional piezoelectric actuators may be considered mid-frequency actuators, e.g., 25-35 kHz.", "Flextensional actuators may take on several embodiments.", "For example, in one embodiment, flextensional actuators are of the Cymbal type, as described in

"present invention comprises a handheld device including a body, a flextensional actuator disposed within said body and a penetrating or “sharps” member attached to one face of the flextensional actuator.", "In the broadest scope of the invention, the penetrating member may be hollow or solid.", "The actuator may have an internal bore running from a distal end to a proximal end or may have a side port located on the penetrating member attachment fitting.", "Therefore for single use penetrating members there is no need to sterilize the penetrating member after use.", "Where the penetrating member is hollow, it forms a hollow tubular structure having a sharpened distal end.", "The hollow central portion of the penetrating member is concentric to the internal bore of the actuator, together forming a continuous hollow cavity from a distal end of the actuator body to a proximal end of the penetrating member.", "For example, the flextensional actuator assembly may utilize flextensional Cymbal actuator technology or amplified piezoelectric actuator (APA) technology.", "The flextensional actuator assembly provides for improved amplification and improved performance, which are above that of a conventional handheld device.", "For example, the amplification may be improved by up to about 50-fold.", "Additionally, the flextensional actuator assembly enables handpiece configurations to have a more simplified design and a smaller format.", "One embodiment of the present invention is a resonance driven vascular entry needle to reduce insertion force of the penetrating member and to reduce rolling or collapsing of vasculature.", "An alternative embodiment of the present invention is a reduction of force epidural needle that provides the clinician a more controlled entry into the epidural space, minimizing the accidental puncturing of the dural sheath.", "In this embodiment, an actuator, for example, a Langevin actuator (more commonly referred to as a Langevin transducer), has a hollow penetrating member, for example a hollow needle, attached to a distal portion of the actuator.", "The Langevin actuator in this embodiment may be open at opposite ends.", "The openings include a hollow portion extending continuously from the distal end of the actuator to a proximal end of the actuator.", "The distal opening coincides with the hollow penetrating member.", "A plunger, having a handle, a shaft and a seal is also attached to the actuator at an opposite end of the sharps member.", "The plunger's shaft is slidably disposed within the continuous, hollowed inner portion of the actuator.", "The seal is attached to a distal portion of the plunger's shaft and separates a distal volume of the hollowed inner portion of the actuator from a proximal volume of the hollowed inner portion.", "Because the plunger's shaft is slidably disposed, the plunger is also slidably disposed and, in response to a motion of the shaft in a distal direction, reduces the distal volume of the hollowed inner portion and increases the proximal volume.", "Conversely, in response to a motion of the shaft in a proximal direction, the seal also moves in a proximal direction, thereby reducing the proximal volume of the hollowed portion and increasing the distal volume.", "The motion of the plunger's shaft, and, effectively, the plunger's seal, is actuated by an external force acting on the plunger's handle.", "When electrically activated, the actuator transfers compression and expansion of the piezoelectric material portion to a hollow and penetrating tip of the hollow needle.", "Langevin actuators may be considered high :frequency actuators, e.g., >50 kHz.", "Another embodiment of the invention provides a bone marrow biopsy device having an outer casing, an actuator, for example, a Langevin actuator (e.g., see, for example, U.S. Pat.", "No.", "6,491,708 (Madan, et al.", "), whose entire disclosure is incorporated by reference herein), including a first body portion and a second body portion of the actuator, with piezoelectric material formed between the first and second body portions, wherein the actuator is disposed at least partially within the casing.", "The invention further includes a handle, an outer cannula, such as a needle, having an open distal end and an open proximal end with the cannula positioned at a distal portion of the actuator.", "In one aspect of the present embodiment, the invention further comprises a stylet having a penetrating distal tip attached to the handle at a portion opposite the distal tip, wherein the stylet is slidably disposed through a center cavity of the body and cannula.", "The actuator is formed with a distal opening formed at a distal end of the actuator, and a proximal opening formed at a proximal end of the actuator with a centralized hollow bore extending from the distal opening to the proximal opening, thereby defining a hollow channel.", "More precisely, the outer cannula is a hollow tube fixedly attached at the distal end of the actuator such that the open proximal end of the cannula coincides with the distal opening of the actuator distal end.", "The stylet is slidably and centrally disposed within the actuator from the proximal end through the hollow channel and through the distal end.", "The stylet is also of predetermined length such that it is slidably and centrally located through the outer cannula, with the distal tip of the stylet protruding past the open distal end of the cannula.", "The various actuators of the present invention must be connected electrically to an external electrical signal source.", "Upon excitation by the electrical signal, the actuators convert the signal into mechanical energy that results in vibratory motion of an end-effector, such as an attached needle or stylet.", "In the case of a Langevin actuator, the vibratory motion produced by the piezoelectric materials generates a standing wave through the whole assembly such as that in graph in FIG.", "17 .", "Because at a given frequency, a standing wave is comprised of locations of zero-displacement (node, or zero node) and maximum displacement (anti-node—not shown) in a continuous manner, the displacement that results at any point along the actuator depends on the location where the displacement is to be measured.", "Therefore, the horn is typically designed with such a length so as to provide the distal end of the horn at an anti-node when the device is operated.", "In this way, the distal end of the horn experiences a large vibratory displacement in a longitudinal direction with respect to the long axis of the actuator.", "Conversely, the zero node points are locations best suited for adding port openings or slots so as to make it possible to attach external devices to the actuator.", "As indicated by line ZN, the port opening SP coincides with the zero node location and the smaller displacement at zero node points are less abrasive to an attached device.", "Accordingly, an alternative embodiment, the actuator may be formed with a distal opening formed at the distal end of the actuator, a port opening on at least a portion of the actuator, and a hollow bore extending from the distal opening to and in communication with the port opening.", "Preferably, the port opening may be a side port on a horn side of the actuator.", "More preferably, the port opening is generally located (preferably centered) at a zero node location of the actuator, and most preferably centered at a zero node location on a horn side of the actuator.", "Additionally, a means for providing feedback, for example any of those conventional feedback devices disclosed above used for indication of successful body location such as the epidural space penetration is in communication with the present embodiment by attachment at the port opening location, or preferably at the side port.", "Alternatively, any means capable of delivering fluid, such as a catheter tube or conventional syringe can be attached at the port opening location, or preferably at the side port.", "The present invention relates generally to oscillatory or translational actuated handheld device for penetration through various tissues within a body for the delivery or removal of bodily fluids, tissues, nutrients, medicines, therapies, placement or removal of catheters, etc.", "For example for piezoelectric devices, the present invention is a handpiece including a body, at least one piezoelectric element disposed within the body, and a sharps member for tissue penetration, such as a syringe, epidural needle or biopsy needle located at a distal portion of the handheld device, having a feedback means capable of indicating successful penetration of the body space, such as epidural space by providing visual, audible or tactile indications using any well-known detection mechanisms such as but not limited to electrical, magnetic, pressure, capacitive, inductive, etc.", "means.", "Additionally, with the use of proper circuitry the handheld medical device comprising an actuator is provided with a means for shutting off external power to the driving actuator (e.g., one or more of piezoelectric elements, voice coil, solenoid, other oscillatory or translational actuator, etc.)", "upon penetration of a particular tissue or internal portion of a body such as the epidural space.", "The means for shutting off external power to the driving actuator may be implemented as part of the aforementioned means for providing visual, audible or tactile indications or may be a separate means altogether.", "Preferably the means for shutting off external power to the driving actuator upon penetration of a particular tissue or internal portion of for example, the epidural space, may be accomplished by incorporating proper circuit configurations to aforementioned electrical means to trigger a switching means in order to cut off power to the driving actuator.", "Such a means is described in U.S. Pat.", "No.", "5,575,789 (Bell et al.)", "whose entire disclosure is incorporated by reference herein.", "By providing such electrical cut-off means, upon successfully penetrating the epidural space for example, a clinician receives one or more of a visual, audible, and tactile indications as well as a loss of power to the device as a secondary indication that a particular internal portion of a body has been penetrated.", "Furthermore, with a loss of power to the device by cutting off electrical power to the driving actuator, the force or forward momentum necessary for further penetration of tissue will cease and in turn, will decrease the potential for unwanted body area puncture such as accidental dural puncture.", "Additionally the invention with specific control electronics will provide reduction of force as the penetrating member is retracted from the body.", "In one embodiment, the penetrating or

This invention was made with government support under GM085844, RR024943, CA139774, and GM100535 awarded by the National Institutes of Health.", "The government has certain rights in the invention.", "BACKGROUND OF THE INVENTION Field of the Invention The present invention generally pertains to handheld medical devices, and more specifically to electrically driven lancets; epidural catheter inserters; biopsy medical instruments, such as bone biopsy medical devices; vascular entry penetrating members, spinal access needles and other catheterization needles.", "The invention is applicable to the delivery and removal of blood, tissues, medicine, bone marrow, nutrients or other materials within the body.", "Description of Related Art Epidural anesthesia is a form of regional anesthesia involving injection of drugs directly into the epidural space.", "To begin the procedure, a needle is inserted from the outer layer of skin, through several layers of tissue and finally placed within the epidural space, through which a catheter is optionally passed.", "Local anesthetics are injected into the epidural space causing temporary loss of sensation and pain by blocking the transmission of pain signals through nerves in or near the spinal cord.", "The procedure can be unpleasant to the patient because of the high force levels required for the relatively dull epidural needle to penetrate the supraspinous ligament, interspinous ligament and ligamentum flavum.", "One complication is that a clinician will accidently overshoot and puncture the dura because of this high force of penetration and an almost-instantaneous change in resistance upon passing the needle into the epidural space (i.e., high forward momentum followed by instantaneous minimization of force).", "Upon puncturing the dura, the cerebrospinal fluid can leak into the epidural space causing the patient to experience severe post dural puncture headache, lasting from days to possibly years.", "Significant leakage can cause enough intracranial hypotension as to tear veins, cause subdural hematoma, and traction injuries to the cranial nerves resulting in tinnitus, hearing loss, dizziness, facial droop, or double vision.", "A bone marrow biopsy is used for diagnosing tumors and a variety of bone diseases.", "The most commonly used site for the bone biopsy is the anterior iliac crest.", "A major disadvantage is the force required to penetrate the bone tissue, and the twisting motion often used to force the needle inward, which results in patient discomfort as well as possible healing complications from damaged tissues.", "The penetration force can also be tiring for clinicians and lead to multiple sampling attempts.", "Complications are rare but can include bleeding, pain, and infection.", "Pain is minimized with proper local anesthesia, though the patient still experiences a pressure sensation during insertion and retraction during some procedures.", "Another problem is crushing the sample or being unable to retrieve part of all of it, limiting the ability to diagnose.", "As shown in FIG.", "1, a biopsy tool PA1 typically comprises a handle (not shown) and hollow cannula 1 with cannula distal end 1′ surrounding a stylet 2 attached to the handle.", "To penetrate through cortical bone, a clinician pushes the cannula and stylet through the bone to the marrow.", "The distal tip 3 of the inner stylet or trocar is sharpened and has an angled chisel-like face 4 which reduces the surface area to reduce the exertion force.", "Currently, to minimize the possibility of a dura puncture, the epidural catheter insertion process is typically performed very slowly and with a 16-18 gauge, specially designed, relatively dull needle PA2, such as the one shown in FIG.", "2 called a Tuohy needle 5.An epidural needle, such as the Tuohy needle 5 or Hustead needle, has a directional curved tip 6, which decreases the “sharpness” at the needle and, therefore, makes accidental dura puncture more difficult.", "The curved tip also facilitates directing an indwelling catheter into the epidural space and a tip opening 7 facilitates catheter or fluid introduction or removal.", "Unfortunately, this dull curved-tip design actually increases the force a clinician must use and makes it more difficult for a clinician to stop the forward momentum upon penetration of the dural space.", "Additionally, the Tuohy design increases the likelihood that a clinician relies on tactile feedback during penetration.", "In other words, during the insertion procedure a clinician will rely on feeling a “popping” sensation—indicative of passing the needle past the ligamentum flavum—to locate the tip of the needle within the epidural space and quickly stop the forward momentum being applied.", "Still, because penetration into other tissues, such as muscle, calcified ligament, or regular ligament may produce a similar popping, a clinician may not fully perceive the correct location of the needle tip where the tip of the needle is occluded until passing through these tissues.", "Several alternate technologies have been developed that attempt to minimize the dura puncture risk, while also giving the clinician indication of successful epidural placement.", "For example, the detection method and apparatus disclosed in U.S. Patent Application Publication No.", "2007/0142766 (Sundar, et al.", "), the contents of which are incorporated by reference, relies on a spring-loaded plunger pushing a fluid into the epidural space upon successful entry.", "Accordingly, the clinician is given a visual indicator (i.e., the movement of the plunger as the fluid experiences a loss of resistance at the needle opening), and would cease applying forward force.", "Similarly, U.S. Pat.", "No.", "5,681,283 (Brownfield) also relies on a visual indicator to communicate successful entry of a needle into a cavity to the clinician.", "Unfortunately, while a visual indicator is a positive advancement, the actual cause of the accidental dural wall puncture—that is, the high force applied by the clinician against the needle to pass through the various tissue layers and then stop—is not taught or suggested.", "Therefore, there exists a need for a tool that reduces the puncture force of a needle, such as a Tuohy needle, and enables a clinician to perform a more controlled entry into the epidural space, thereby reducing the possibility of an accidental dura puncture.", "While accidental dura puncture is a concern, simply locating the epidural space may pose a challenge even to the most skilled physicians.", "Therefore, when a needle such as a Tuohy needle is passed through the ligamentum flavum and into the epidural space, it is helpful for a clinician to receive immediate feedback indicating successful penetration and the location of the tip of the needle.", "A basic conventional feedback device such as the one in FIG.", "2a comprises a needle (not shown) attached to a syringe PA3 at a front portion 9, and wherein the syringe PA3 is formed of a tubular body 10 and houses a biasing element 11 comprising a stem acting as a biasing element.", "To provide feedback indicating successful epidural penetration the device relies on a biasing force acting against the biasing element 11 which then acts upon a fluid, such as saline or air within the syringe.", "Essentially, in this hydraulic feedback method, as the biasing force acts upon the fluid, the fluid translates this pressure to an opening of the needle tip.", "An opposing force, acting on the needle tip as it is held against a tissue such as the ligamentum flavum, acts to prevent the fluid from being released from the syringe.", "Typically, a clinician's thumbs act as the biasing force source which in turn acts upon the plunger stem.", "The clinician's thumbs serve to “feel” the hydraulic resistance exerted on the fluid by the opposing tissue force.", "Upon entering the epidural space, however, the opposing pressure of tissue acting against the tip is removed, and a pressure drop allows the biasing force to move solution out of the syringe through the needle tip.", "The clinician becomes aware of successful penetration of the epidural space due to his/her thumbs “feeling” the sudden pressure drop or loss of resistance at the plunger stem.", "Also, the clinician may receive visual indication of successful penetration by witnessing the plunger advancing through the syringe externally as the fluid is released into the epidural space in the patient.", "One problem with this conventional device and method is that it is difficult for a clinician to both apply a biasing force on the plunger while also applying an advancing force against the syringe body in order to advance the needle through the ligamentum flavum.", "Moreover, to prevent accidental dura puncture, clinicians tend to hold the conventional syringe in such a way as to hold the patient steady, while applying a forward momentum against the syringe, and while applying a biasing force against the plunger stem.", "This is both awkward and uncomfortable to the clinician and patient.", "Some advancements have also attempted to provide an automatic biasing element to act against the plunger of an epidural syringe while also providing visual indication or feedback, rather than tactile response, of successful puncture of various internal target areas in the human body.", "For example, in U.S. Patent Publication No.", "2007/0142766 (Sundar et al.", "), a spring is utilized to act with a biasing force against the syringe plunger.", "When the epidural needle attached to the syringe passes through into the dural space, the pressure drop allows the spring to bias the plunger.", "As the plunger moves, the stem provides at least some visual indication as it moves with the plunger.", "Similarly, U.S. Pat.", "No.", "5,024,662 (Menes et al.", "), which is hereby incorporated by reference, provides visual indication by utilizing an elastomer band to provide the biasing force against the plunger stem.", "In U.S. Pat.", "No.", "4,623,335 (Jackson) which is hereby incorporated by reference, an alternative device assists in visually indicating a pressure to identify the location of the needle tip.", "In addition, U.S. Pat.", "No.", "7,297,131 (Call) which is hereby incorporated by reference, uses a pressure transducer to translate a pressure change into an electronic signal.", "The electronic signal is then converted to a visual display indicator, for example by activating a light emitting diode to emit.", "Therefore, a need exists to overcome the challenges not addressed by conventionally available technologies that reduces the force necessary for penetration of a sharp medical element of a medical device through tissue and also has the ability to deliver (e.g., deliver saline solution, or drugs, etc.)", "or retrieve materials subcutaneously (e.g., bone biopsy, etc.).", "A need also exists to provide visual, tactile, electrical or additional indication to a clinician that the penetrating member has successfully penetrated the specific body space such as the epidural space, especially when the force to enter such a space has been substantially reduced.", "And this same force reduction must be either controlled or shut off immediately upon entry into the epidural space to avoid (easier) penetration of the dura.", "Specifically, a need exists in the medical device art for an improved medical device having a penetrating element that is vibrated at a frequency that thereby reduces the force required to penetrate tissue, reduces the amount of resulting tissue damage and scarring, improving body space or vessel access success rate, minimizes introduction wound site trauma and, most importantly, improves patient comfort while minimizing potential complications.", "A need exists for a clinician to be able to use less force to penetrate hard tissue such as the cortical bone during bone biopsy; which would reduce clinician fatigue, patient discomfort; and tissue damage while improving the sampling success rate and quality.", "There is a need to sense proper location, stop forward motion and collect the sample.", "There is a further need to tum device on after collection and to reduce force and patient discomfort as the penetrating member is being retracted from the body.", "There is also a need for spinal access procedures where a clinician would want a reduction of force as well as to know the location of the needle tip but applied to a relatively-sharp penetrating member, such as a pencil point tip, as the clinician does not want to core tissue.", "There is also a need for performing nerve block procedures where a clinician would want a reduction of force as well as to know the location of the needle tip.", "And this same force reduction must be either controlled or shut off immediately upon entry into the desired location.", "All references cited herein are incorporated herein by reference in their entireties.", "SUMMARY OF THE INVENTION The basis of the invention is a handheld medical device, (e.g., epidural needle, bone biopsy device, spinal needle, regional block needle, catheter introducer needle, etc.)", "having a penetrating member (e.g., an introducer needle, Tuohy needle, pencil point tipped needle, trocar needle (e.g., JAMSHIDI® biopsy needle), etc.", "), at a distal end, for use in procedures, (e.g., vascular entry and catheterization, single shot or continuous epidurals, spinal access, regional blocks, or bone biopsy, etc.", "), wherein the medical device comprises at least one driving actuator, (e.g., a piezoelectric, voice coil, solenoid, pneumatic, fluidic or any oscillatory or translational actuator etc.)", "attached to the penetrating member (e.g., at a proximal end of the penetrating member), and wherein the driving actuator translates the penetrating member, causing it to reciprocate at small displacements, thereby reducing the force required to penetrate through tissues.", "Additionally, the invention comprises a means for providing feedback, either visually, audibly, or by tactile response, using a variety of detection mechanisms (such as, but not limited to, electrical, magnetic, pressure, capacitive, inductive, etc.", "means), to indicate successful penetration of various tissues, or of voids within the body such as the epidural space so that the clinician knows when to stop as well as to limit power to the driving mechanism.", "Actuator technologies that rely on conventional, single or stacked piezoelectric material assemblies for actuation are hindered by the maximum strain limit of the piezoelectric materials themselves.", "Because the maximum strain limit of conventional piezoelectric materials is about 0.1% for polycrystalline piezoelectric materials, such as lead zirconate titanate (PZT) polycrystalline (also referred to as ceramic) materials and 0.5% for single crystal piezoelectric materials, it would require a large stack of cells to approach useful displacement or actuation of, for example, a handheld medical device usable for processes penetrating through tissues.", "However, using a large stack of cells to actuate components of a handpiece would also require that the tool size be increased beyond usable biometric design for handheld instruments.", "Flextensional actuator assembly designs have been developed which provide amplification in piezoelectric material stack strain displacement.", "The flextensional designs comprise a piezoelectric material driving cell disposed within a frame, platen, endcaps or housing.", "The geometry of the frame, platten, endcaps or housing provides amplification of the axial or longitudinal motions of the driver cell to obtain a larger displacement of the flextensional assembly in a particular direction.", "Essentially, the flextensional actuator assembly more efficiently converts strain in one direction into movement (or force) in a second direction.", "Flextensional piezoelectric actuators may be considered mid-frequency actuators, e.g., 25-35 kHz.", "Flextensional actuators may take on several embodiments.", "For example, in one embodiment, flextensional actuators are of the Cymbal type, as described in U.S. Pat.", "No.", "5,729,077 (Newnham), which is hereby incorporated by reference.", "In another embodiment, flextensional actuators are of the amplified piezoelectric actuator (“APA”) type as described in U.S. Pat.", "No.", "6,465,936 (Knowles), which is hereby incorporated by reference.", "In yet another embodiment, the actuator is a Langevin or bolted dumbbell-type actuator, similar to, but not limited to that which is disclosed in U.S. Patent Application Publication No.", "2007/0063618 A1 (Bromfield), which is hereby incorporated by reference.", "In a preferred embodiment, the.", "present invention comprises a handheld device including a body, a flextensional actuator disposed within said body and a penetrating or “sharps” member attached to one face of the flextensional actuator.", "In the broadest scope of the invention, the penetrating member may be hollow or solid.", "The actuator may have an internal bore running from a distal end to a proximal end or may have a side port located on the penetrating member attachment fitting.", "Therefore for single use penetrating members there is no need to sterilize the penetrating member after use.", "Where the penetrating member is hollow, it forms a hollow tubular structure having a sharpened distal end.", "The hollow central portion of the penetrating member is concentric to the internal bore of the actuator, together forming a continuous hollow cavity from a distal end of the actuator body to a proximal end of the penetrating member.", "For example, the flextensional actuator assembly may utilize flextensional Cymbal actuator technology or amplified piezoelectric actuator (APA) technology.", "The flextensional actuator assembly provides for improved amplification and improved performance, which are above that of a conventional handheld device.", "For example, the amplification may be improved by up to about 50-fold.", "Additionally, the flextensional actuator assembly enables handpiece configurations to have a more simplified design and a smaller format.", "One embodiment of the present invention is a resonance driven vascular entry needle to reduce insertion force of the penetrating member and to reduce rolling or collapsing of vasculature.", "An alternative embodiment of the present invention is a reduction of force epidural needle that provides the clinician a more controlled entry into the epidural space, minimizing the accidental puncturing of the dural sheath.", "In this embodiment, an actuator, for example, a Langevin actuator (more commonly referred to as a Langevin transducer), has a hollow penetrating member, for example a hollow needle, attached to a distal portion of the actuator.", "The Langevin actuator in this embodiment may be open at opposite ends.", "The openings include a hollow portion extending continuously from the distal end of the actuator to a proximal end of the actuator.", "The distal opening coincides with the hollow penetrating member.", "A plunger, having a handle, a shaft and a seal is also attached to the actuator at an opposite end of the sharps member.", "The plunger's shaft is slidably disposed within the continuous, hollowed inner portion of the actuator.", "The seal is attached to a distal portion of the plunger's shaft and separates a distal volume of the hollowed inner portion of the actuator from a proximal volume of the hollowed inner portion.", "Because the plunger's shaft is slidably disposed, the plunger is also slidably disposed and, in response to a motion of the shaft in a distal direction, reduces the distal volume of the hollowed inner portion and increases the proximal volume.", "Conversely, in response to a motion of the shaft in a proximal direction, the seal also moves in a proximal direction, thereby reducing the proximal volume of the hollowed portion and increasing the distal volume.", "The motion of the plunger's shaft, and, effectively, the plunger's seal, is actuated by an external force acting on the plunger's handle.", "When electrically activated, the actuator transfers compression and expansion of the piezoelectric material portion to a hollow and penetrating tip of the hollow needle.", "Langevin actuators may be considered high :frequency actuators, e.g., >50 kHz.", "Another embodiment of the invention provides a bone marrow biopsy device having an outer casing, an actuator, for example, a Langevin actuator (e.g., see, for example, U.S. Pat.", "No.", "6,491,708 (Madan, et al.", "), whose entire disclosure is incorporated by reference herein), including a first body portion and a second body portion of the actuator, with piezoelectric material formed between the first and second body portions, wherein the actuator is disposed at least partially within the casing.", "The invention further includes a handle, an outer cannula, such as a needle, having an open distal end and an open proximal end with the cannula positioned at a distal portion of the actuator.", "In one aspect of the present embodiment, the invention further comprises a stylet having a penetrating distal tip attached to the handle at a portion opposite the distal tip, wherein the stylet is slidably disposed through a center cavity of the body and cannula.", "The actuator is formed with a distal opening formed at a distal end of the actuator, and a proximal opening formed at a proximal end of the actuator with a centralized hollow bore extending from the distal opening to the proximal opening, thereby defining a hollow channel.", "More precisely, the outer cannula is a hollow tube fixedly attached at the distal end of the actuator such that the open proximal end of the cannula coincides with the distal opening of the actuator distal end.", "The stylet is slidably and centrally disposed within the actuator from the proximal end through the hollow channel and through the distal end.", "The stylet is also of predetermined length such that it is slidably and centrally located through the outer cannula, with the distal tip of the stylet protruding past the open distal end of the cannula.", "The various actuators of the present invention must be connected electrically to an external electrical signal source.", "Upon excitation by the electrical signal, the actuators convert the signal into mechanical energy that results in vibratory motion of an end-effector, such as an attached needle or stylet.", "In the case of a Langevin actuator, the vibratory motion produced by the piezoelectric materials generates a standing wave through the whole assembly such as that in graph in FIG.", "17.Because at a given frequency, a standing wave is comprised of locations of zero-displacement (node, or zero node) and maximum displacement (anti-node—not shown) in a continuous manner, the displacement that results at any point along the actuator depends on the location where the displacement is to be measured.", "Therefore, the horn is typically designed with such a length so as to provide the distal end of the horn at an anti-node when the device is operated.", "In this way, the distal end of the horn experiences a large vibratory displacement in a longitudinal direction with respect to the long axis of the actuator.", "Conversely, the zero node points are locations best suited for adding port openings or slots so as to make it possible to attach external devices to the actuator.", "As indicated by line ZN, the port opening SP coincides with the zero node location and the smaller displacement at zero node points are less abrasive to an attached device.", "Accordingly, an alternative embodiment, the actuator may be formed with a distal opening formed at the distal end of the actuator, a port opening on at least a portion of the actuator, and a hollow bore extending from the distal opening to and in communication with the port opening.", "Preferably, the port opening may be a side port on a horn side of the actuator.", "More preferably, the port opening is generally located (preferably centered) at a zero node location of the actuator, and most preferably centered at a zero node location on a horn side of the actuator.", "Additionally, a means for providing feedback, for example any of those conventional feedback devices disclosed above used for indication of successful body location such as the epidural space penetration is in communication with the present embodiment by attachment at the port opening location, or preferably at the side port.", "Alternatively, any means capable of delivering fluid, such as a catheter tube or conventional syringe can be attached at the port opening location, or preferably at the side port.", "The present invention relates generally to oscillatory or translational actuated handheld device for penetration through various tissues within a body for the delivery or removal of bodily fluids, tissues, nutrients, medicines, therapies, placement or removal of catheters, etc.", "For example for piezoelectric devices, the present invention is a handpiece including a body, at least one piezoelectric element disposed within the body, and a sharps member for tissue penetration, such as a syringe, epidural needle or biopsy needle located at a distal portion of the handheld device, having a feedback means capable of indicating successful penetration of the body space, such as epidural space by providing visual, audible or tactile indications using any well-known detection mechanisms such as but not limited to electrical, magnetic, pressure, capacitive, inductive, etc.", "means.", "Additionally, with the use of proper circuitry the handheld medical device comprising an actuator is provided with a means for shutting off external power to the driving actuator (e.g., one or more of piezoelectric elements, voice coil, solenoid, other oscillatory or translational actuator, etc.)", "upon penetration of a particular tissue or internal portion of a body such as the epidural space.", "The means for shutting off external power to the driving actuator may be implemented as part of the aforementioned means for providing visual, audible or tactile indications or may be a separate means altogether.", "Preferably the means for shutting off external power to the driving actuator upon penetration of a particular tissue or internal portion of for example, the epidural space, may be accomplished by incorporating proper circuit configurations to aforementioned electrical means to trigger a switching means in order to cut off power to the driving actuator.", "Such a means is described in U.S. Pat.", "No.", "5,575,789 (Bell et al.)", "whose entire disclosure is incorporated by reference herein.", "By providing such electrical cut-off means, upon successfully penetrating the epidural space for example, a clinician receives one or more of a visual, audible, and tactile indications as well as a loss of power to the device as a secondary indication that a particular internal portion of a body has been penetrated.", "Furthermore, with a loss of power to the device by cutting off electrical power to the driving actuator, the force or forward momentum necessary for further penetration of tissue will cease and in turn, will decrease the potential for unwanted body area puncture such as accidental dural puncture.", "Additionally the invention with specific control electronics will provide reduction of force as the penetrating member is retracted from the body.", "In one embodiment, the penetrating or sharp tubular member is a part of a vascular entry needle.", "In another embodiment, the penetrating sharp tubular member is a Tuohy needle.", "In yet another embodiment, the penetrating or sharp

Force,” filed on Jun.", "27, 2008 is incorporated by reference in its entirety.", "The effectiveness of the invention as described, for example, in the aforementioned preferred embodiments, utilizes reduction of force to optimize penetrating through tissue or materials found within the body.", "Essentially, when tissue is penetrated by the high speed operation of a penetrating member portion of the device, such as a needle, the force required for entry is reduced.", "In other words, a reduction of force effect is observed when a penetrating member (also referred to as a “tubular member”), for example a needle, is vibrated axially (e.g., reciprocated) during the insertion process and enough mechanical energy is present to break adhesive bonds between tissue and the penetrating member.", "The threshold limits of energy can be reached in the sonic to ultrasonic frequency ranges if the necessary amount of needle displacement is present.", "To exploit the reduction of force effect, the medical device of the present invention is designed such that the penetrating distal tip portion attains a short travel distance or displacement, and vibrates sinusoidally with a high penetrating frequency.", "Utilizing the various device configurations as described in the aforementioned embodiments, it has been determined that the sinusoidal motion of the sharp distal tip must include a displacement for piezoelectric tools of between 35-100 μm, more preferably between 50-100 μm, at a frequency of between 20-50 kHz, but most preferably at 20-25 kHz.", "This motion is caused by the

wideband wireless communications and more particularly communications systems exploiting mixerless transmitters and energy based receivers.", "The ensuing description provides exemplary embodiment(s) only, and is not intended to limit the scope, applicability or configuration of the disclosure.", "Rather, the ensuing description of the exemplary embodiment(s) will provide those skilled in the art with an enabling description for implementing an exemplary embodiment.", "It being understood that various changes may be made in the function and arrangement of elements without departing from the spirit and scope as set forth in the appended claims.", "0.Impulse Radio Ultra Wideband System As discussed supra UWB offers many potential advantages such as high data rate, low-cost implementation, and low transmit power, ranging, multipath immunity, and low interference.", "The FCC regulations for UWB reserved the unlicensed frequency band between 3.1 GHz and 10.6 GHz for indoor UWB wireless communication system wherein the low regulated transmitted power allows such UWB systems to coexist with other licensed and unlicensed narrowband systems.", "Therefore, the limited resources of spectrum can be used more efficiently.", "On the other hand, with its ultra wide bandwidth, an UWB system has a capacity much higher than the current narrowband systems for short range applications.", "Two possible techniques for implementing UWB communications are Impulse Radio (IR) UWB and multi-carrier or multi-band (MB) UWB.", "IR-UWB exploits the transmission of ultra-short (of the order of nanosecond) pulses, although in some instances in order to increase the processing gain more than one pulse represents a symbol.", "In contrast MB-UWB systems use orthogonal frequency division multiplexing (OFDM) techniques to transmit the information on each of the sub-bands.", "Whilst OFDM has several good properties, including high spectral efficiency, robustness to RF and multi-path interferences.", "However, it has several drawbacks such as up and down conversion, requiring mixers and their associated high power consumption, and is very sensitive to inaccuracies in frequency, clock, and phase.", "Similarly, nonlinear amplification destroys the orthogonality of OFDM.", "Accordingly, MB-UWB is not suitable for low-power and low cost applications.", "In contrast IR-UWB offers several advantages, including unlicensed usage of several gigahertz of spectrum, offers great flexibility of spectrum usage, and adaptive transceiver designs can be used for optimizing system performance as a function of the data rate, operation range, available power, demanded quality of service, and user preference.", "Further, multi-Gb/s data-rate transmission over very short range is possible and due to the ultra-short pulses within IR-UWB it is very robust against multipath interference, and more multipath components can be resolved at the receiver in some implementations, resulting in higher performance.", "Further, the ultra-short pulses support sub-centimeter ranging whilst the lack of up and down conversion allows for reduced implementation costs and lower power transceiver implementations.", "Beneficially, ultra-short pulses and low power transmissions make IR-UWB communications hard to eavesdrop upon.", "A IR-UWB transmitter as described below in respect of embodiments of the invention in Section 1 with reference to FIGS.", "2 to 19 respectively exploits an on-demand oscillator following a pulse generator in order to up-convert the pulses from the pulse generated whilst avoiding the requirement of a separate mixer.", "Implementable in standard CMOS logic both the pulse generator and the on-demand oscillator are digitally tunable in order to provide control over the pulse bandwidth and center frequency.", "Further, by exploiting a digitally controlled ring oscillator for the on-demand oscillator the IR-UWB transmitter is designed to allow very quick frequency adjustments on the order of the pulse repetition rate (PRR).", "Beneficially this technique provides the same advantages as MB-OFDM in respect of spectrum configurability, achieved by sequentially changing the transmitted spectrum using a frequency hopping scheme, whilst maintaining the benefits of IR-UWB.", "Further, by providing advanced duty cycling with fast power up time combined with On-Off Shift Keying (OOK) modulation the IR-UWB according to embodiments of the invention allows significant reductions in power consumption by exploiting the low duty cycle of a UWB symbol and the fact that only half the symbols require sending energy.", "In addition to defining the operating frequency range for UWB systems the different regulatory bodies all specify and enforce a specific power spectral density (PSD) mask for UWB communications.", "The PSD mask employed in respect of embodiments of the invention described below in Section 3 and in respect of FIGS.", "20 to 30B is the FCC mask for which mask data are summarized in Table 1 below for the 3100 MHz-10600 MHz (3.1 GHz-10.6 GHz) range.", "TABLE 1 FCC Masks for Indoor - Outdoor for Different Frequency Bands Indoor EIRP Limit Outdoor EIRP Frequency Range (dBm/MHz) Limit (dBm/MHz) <960 −−49.2 −49.2 960-1610 MHz −75.3 −75.3 1610-1990 MHz −53.3 −63.3 1990-3100 MHz −51.3 −61.3 3100-10600 MHz −41.3 −41.3 >10600 MHz −51.3 −61.3 Accordingly, it would be evident that the upper limit of −41.3 dB/MHz across the 3.1 GHz-10.6 GHz frequency range is the same limit imposed on unintentional radiation for a given frequency in order not to interfere with other radios.", "Basically, for a given frequency, the UWB radio operates under the allowed noise level which creates the relationship presented in Equation (1) between Ep, the transmitted energy per pulse, the maximum spectral power S, the bandwidth B, the bit rate Rb and the number of pulses per bits Nppb.", "Ep·Nppb·Rb≤S·B (1) The IEEE has published a few standards for a physical layer (PHY) for UWB radio in Personal Area Networks (IEEE 802.15.4a-2007), Body Area Networks (IEEE 802.15.4a-2007) and Radio-Frequency Identification (IEEE 802.15.4f-2012).", "These standards use mostly relatively large pulses resulting in relatively narrow bandwidth which is up-converted to a specific center frequency in order to fill predetermined channels.", "The data is encoded using pulse-position-modulation (PPM) and bi-phasic shift keying (BPSK) is used to encode redundancy data.", "Every bit consists of one or more pulses scrambled in phase depending on the target data rate.", "These standards allow considerable flexibility on channel availability and data rates.", "The standard also defines the preamble, headers for the data packet and ranging protocol.", "These IEEE standards are designed with multiple users in mind and use different channels to transmit the data, thereby putting a heavy constraint on pulse bandwidth and limiting the transmitted energy.", "Prior art on non-standard transmitter attempts to make better use of the available spectrum by using narrow pulses, which therefore have a larger bandwidth thereby increasing the maximum transmitted energy according to Equation (1).", "Accordingly, these transmitters are non-standard and were also designed for different data rates, frequencies, pulse width, etc.", "Additionally, they also used various encoding schemes, most notably PPM, OOK or BPSK.", "Within this work the inventors have established an energy receiver which is able to adapt to a variety of IR-UWB pulses and bit encoding thereby supporting communications from both IR-UWB transmitters compliant to IEEE standards as well as those that are non-standard.", "However, as energy detection based receivers have no way to extract the phase of the received pulses they cannot detect any modulation involving phase detection such as BPSK.", "However, most of the other encodings can be translated in some way into energy levels and proper timing.", "This requires in turn the ability to achieve synchronization and to adjust the integration windows appropriately.", "Accordingly, an IR-UWB communications link requires a transmitter generating the ultra-short pulses and a receiver to receive them.", "In many applications these are also co-located as a transceiver.", "It would be beneficial for these to be implemented using designs compatible with CMOS electronics allowing low cost high volume manufacturing that leverages existing foundry capabilities as well as allowing the IR-UWB transceiver to be integrated with additional electronics such as sensor interfaces, microelectromechanical sensors fabricated through silicon micromachining and/or post-CMOS processing, microprocessors, microcontrollers, etc.", "1.IR-UWB Transmitter Circuit 1A.", "Transmitter Overview: As depicted in FIG.", "2 an IR-UWB transmitter 200 according to embodiments of the invention is composed of five main blocks plus the antenna.", "First a programmable impulse is produced by a pulse generator 230 at clocked intervals when the data signal from AND gate 210 is high based upon control signals presented to the AND gate 210.The pulses from the pulse generator 230 are then up-converted with a programmable multi-loop digitally controlled ring oscillator (DCRO) 240, such as that described by Gerosa et al in “A Digitally Programmable Ring Oscillator in the UWB Range” (IEEE Int.", "Symp.", "Circuits and Systems 2010, pp.", "1101-1104).", "The output from the DCRO 240 is then coupled to a variable gain amplifier (VGA) 250 in order to compensate for any frequency dependency of the pulse amplitude.", "Finally, a driver 260 feeds the antenna 270, overcoming typical package parasitics, such as arising from packaging the transceiver within a quad-flat no-leads (QFN) package.", "In order to further reduce the power consumption of the IR-UWB transmitter (IR-UWB-Tx) 200

FIG.", "3 there is depicted a circuit schematic 300 of a pulse generator 220 according to an embodiment of the invention implementable in CMOS wherein the pulse generator 220 generates a pulse approximating a Gaussian shape when triggered by a rising edge of an input Vin.", "The input is obtained from AND gate 210 from a pulse clock and the data signal.", "This allows full control over the final symbol shape.", "The pulse repetition rate (PRR) is determined by the clock signal frequency and the number of pulses generated depends on the length of the data signal high time whilst the period of the data signal determines the data rate.", "Initially, the node X is charged to Vdd and Q2 362 is in cutoff.", "When Vin goes high, Q1 361 is cut-off and Q3 371 is turned on, transferring the Vdd level to the input of the first inverter 381.The signal then propagates through second to fifth inverters 382 to 385 respectively to generate the output, Vout, thereby creating the rising edge of the impulse.", "When Vout is high, Q2 362 is activated and the node X discharges which toggles the first inverter 381.This propagates through the inverter chain, comprising second to fifth inverters 382 to 385 respectively, lowering Vout thereby creating the falling edge of the pulse.", "When Vin goes low again between pulses, node X is allowed to recharge, re-arming the pulse generator for the following rising edge of the input.", "To ensure sufficient drive between the inverter chain, first to fifth inverters 381 to 385 respectively, and the following VCRO 240 an output buffer 330 is added at the end.", "The pulse width generated is based on the delay through the five inverter chain, first to fifth inverters 381 to 385 respectively, of which four are programmable, namely second

first to fourth resistor pairs Q5 to Q8 342 to 345 respectively and ground via fifth to eighth resistor pairs Q10 to Q13 352 to 355 respectively.", "One of the transistors of a pair is always on,

PI3K pathway and mTORC1.PIK3CA, the gene encoding the alpha isoform of PI3K (PI3Kα, p110α), is frequently mutated in breast cancer, resulting in increased levels of active PI3K, and increased levels of active mTORC1, a downstream target of PI3K.", "Accordingly, the development of inhibitors that selectively target this isoform may be therapeutically beneficial.", "However, a proportion of PIK3CA-mutant patients remain insensitive to PI3Kαblockade.", "3.SUMMARY OF THE INVENTION The present invention relates to methods of inhibiting growth and proliferation of cancer cells resistant to PI3K inhibition using a combination of PDK1 and PI3K inhibitors, or SGK1 and PI3K inhibitors.", "It is based, at least in part, on the discoveries that (i) in cells that are resistant to PI3K inhibition (i.e., the cells express active mTORC1 in the presence of PI3K and AKT inactivation), PDK1 activates mTORC1 through a PI3K independent pathway involving SGK1; (ii) combined inhibition of PI3K and PDK1, or PI3K and SGK1, in cells resistant to PIK3 inhibitor monotherapy resensitizes the cells to the PI3K inhibitor and reduces mTORC1 activity and (iii) combination therapy with PI3K and PDK1 inhibition, or PI3K and SGK1 inhibition, reduced tumor size in vivo in xenografts of PI3K resistant cells.", "In certain non-limiting embodiments, the present invention provides for methods of

relates to methods and compositions for inhibiting growth and proliferation of cancer cells resistant to PI3K inhibition using a combination of PDK1 and PI3K inhibitors.", "It is based, at least in part, on the discovery that inhibition of PDK1 is able to sensitize cancer cells to PI3K inhibitors in cellular and in vivo models.", "Without being bound to any theory, PDK1 activates different kinases of the AGC kinase family via phosphorylation.", "In one non-limiting example, PI3K inhibitors do not exhibit an antitumoral effect in breast cancer cells that express high levels of SGK1.In such cells, SGK1 can activate mTORC1, which confers resistance to PI3K inhibitors.", "By inhibiting PDK1 in these tumors, the activity of SGK1 is subsequently inhibited, and the cells are sensitized to PI3K inhibitors, which can inhibit tumor cell growth and survival.", "Accordingly, in a non-limiting embodiment of the present invention, there is an interaction between a PI3K pathway and a PDK1/SGK1 pathway to activate mTORC1 in cells resistant to PI3K inhibitor activity (i.e., cells that express active mTORC1 in the presence of PI3K inhibition), whereby inhibiting both PI3K activity and PDK1 and/or SGK1 activity reduces tumor cell growth and survival.", "As used herein, the use of the word “a” or “an” when used in conjunction with the term “comprising” in the claims and/or the specification may mean “one,” but it is also consistent with the meaning of “one or more,” “at least one,” and “one or more than one.” Still further, the terms “having,” “including,” “containing” and “comprising” are interchangeable and one of skill in the art is cognizant that these terms are open ended terms.", "The term “about” or “approximately” means within an acceptable error range for the particular value as determined by one of ordinary skill in the art, which will depend in part on how the value is measured or determined, i.e., the limitations of the measurement system.", "For example, “about” can mean within 3 or more than 3 standard deviations, per the practice in the art.", "Alternatively, “about” can mean a range of up to 20%, preferably up to 10%, more preferably up to 5%, and more preferably still up to 1% of a given value.", "Alternatively, particularly with respect to biological systems or processes, the term can mean within an order of magnitude, preferably within 5-fold, and more preferably within 2-fold, of a value.", "For clarity of description and not by way of limitation, the detailed description of the invention is divided into the following subsections: (i) PI3K, PDK1 and SGK1; (ii) PI3K, PDK1 and SGK1 inhibitors; (iii) pharmaceutical compositions; (iv) methods of treatment; and (v) kits.", "The following are terms relevant to the

likelihood of developing cancer.", "An effective amount can be administered in one or more administrations.", "As used herein, and as well-understood in the art, “treatment” is an approach for obtaining beneficial or desired results, including clinical results.", "For purposes of this subject matter, beneficial or desired clinical results include, but are not limited to, alleviation or amelioration of one or more symptoms, diminishment of extent of disease, stabilized (i.e., not worsening) state of disease, prevention of disease, delay or slowing of disease progression, and/or

Summary PIK3CA, the gene encoding the alpha isoform of PI3K (PI3Kα), is frequently mutated in breast cancer, providing the rationale for the development of inhibitors that selectively target this isoform.", "Despite the promising clinical activity of these agents, a proportion of PIK3CA-mutant patients remain insensitive to PI3Kα blockade.", "We have previously reported that residual mTORC1 activity upon treatment with PI3Kα inhibitors limits sensitivity to these agents in breast cancer.", "However, the underlying mechanisms that mediate this phenotype are not fully understood.", "Here, we show that in resistant cells, SGK1 can activate mTORC1 via phosphorylation of TSC2 in a process that requires PDK1.Targeting either PDK1 or SGK1 can restore the antitumoral effect of PI3Kα inhibitors in resistant breast cancer cells.", "Introduction The PI3K pathway integrates many extracellular stimuli, triggering the phosphorylation of key downstream effectors such as AKT and the mammalian Target of Rapamycin Complex 1 and 2 (mTORC1 and 2).", "This signaling cascade is essential for regulating cell size, proliferation, survival, and metabolism.", "Activation of PI3K results in the synthesis of the second messenger phosphatidylinositol-(3,4,5)-triphosphate (PIP3) at the plasma membrane, which in turn promotes the recruitment of the pleckstrin homology (PH) domain-containing proteins PDK1 and AKT.", "The physical proximity at the plasma membrane allows PDK1, a constitutively active kinase, to phosphorylate AKT at the activation loop (T308).", "A second phosphorylation in the hydrophobic motif (S473) is then carried out by mTORC2 to fully activate AKT.", "Once active, AKT is able to phosphorylate a variety of substrates including antiapoptotic and cell cycle related proteins or transcription factors.", "Moreover, AKT predominantly mediates the crosstalk between the PI3K pathway and mTORC1.Activating mutations in PIK3CA, the gene that encodes for the α isoform of the p110 catalytic subunit of PI3K (PI3Kα), loss of function of phosphatase and tensin homolog (PTEN), the phosphatase that modulates levels of PIP2, and overexpression of membrane-bound receptor tyrosine kinases result in hyperactivation of the PI3K/AKT/mTOR pathway.", "These events are common in breast cancer and provide the rationale for the development of inhibitors targeting the different nodes of the PI3K pathway.", "PI3Kα specific inhibitors are currently showing promising results in patients with tumors bearing activating mutations in PIK3CA.", "However, despite these encouraging results, some patients treated with these agents remain insensitive.", "Understanding the molecular mechanisms by which these tumors bypass the pharmacological inactivation of PI3Kα is crucial for the identification of patients that are more likely to respond to these inhibitors and for testing therapeutic options to prevent or delay the emergence of drug resistance.", "We have previously reported that the activation status of mTORC1 upon PI3Kα blockade is a determinant of drug sensitivity in PIK3CA-mutant tumors.", "Despite full inhibition of PI3K/AKT, the presence of residual mTORC1 activity is sufficient to weaken the antitumor activity of PI3Kα inhibition.", "Resistant tumors are re-sensitized by co-treatment with the mTORC1 allosteric inhibitor everolimus, underscoring the causative

active kinase PDK1 overcomes resistance to PI3Kα inhibitors in PIK3CA-mutant breast cancer cells insensitive to these agents.", "We discovered that in the presence of low levels of PIP3 and full suppression of AKT as a result of PI3Kα inhibition, SGK1 contributes to the maintenance of residual mTORC1 activity and cell survival through direct phosphorylation and inhibition of TSC2.Suppression of either PDK1 or SGK1 sensitizes resistant cells to the antitumor activity of PI3Kα blockade, underscoring the causative role of this signaling pathway in inducing the resistance phenotype (FIG.", "15).", "The combination of PI3Kα and PDK1 inhibitors may be of great interest in cases where resistance is driven by alternative AGC kinases such as S6K, RSK, PKC, or others (Elkabets et al., 2015; Elkabets et al., 2013; Serra et al., 2013).", "Summarizing our current knowledge, resistance to PI3Kα inhibitors in PIK3CA-mutant malignancies may occur either as a result of PI3K-dependent or -independent mechanisms.", "An example of PI3K-dependent acquired resistance mechanism has recently been shown by the observation that loss of PTEN results in activation of PI3K p110β and therefore forfeiting PI3Kα signaling (Juric et al., 2015).", "Similarly, reactivation of PI3K p110β signaling has also been revealed to be a mechanism of adaptive resistance in PI3Kα-driven cells (Costa et al., 2015).", "In terms of PI3K-independent mechanisms, we now propose that mTORC1 sustained activity is, at least in part, mediated by PDK1-SGK1 signaling.", "In this context, AKT activity would be dispensable for cell survival, in accordance with previous reports showing that AKT activity is not always required for the downstream PI3K signaling (Gasser et al., 2014; Vasudevan et al., 2009).", "The role of SGK1 in mediating mTORC1 activation upon PI3Kα inhibition can be explained by the differential regulation of AKT and SGK1 upon pharmacological stress.", "Although both kinases share the same upstream regulators, mTORC2 and PDK1, AKT contains a PH domain that is required for the PI3K-dependent plasma membrane translocation and subsequent activation.", "In contrast, SGK1 does not require plasma membrane localization, which could partially explain why it remains active in the absence of PIP3.In our resistant cell lines treated with PI3Kα inhibitor, we observe a substantial but incomplete decrease in SGK1 activity.", "This can be partially explained by the fact that PIP3 controls mTORC2 (Gan et al., 2011), in a mechanism that seems to require mSIN1 (Liu et al., 2015).", "However, other PIP3-independent pools of mTORC2 that are not regulated by growth factors (Frias et al., 2006) might be responsible for residual SGK1 activity.", "While PDK1 is a constitutively active kinase and can be present in both the cytoplasm and membrane (upon PIP3 synthesis), the subcellular localization of mTORC2 is ambiguous (Cybulski and Hall, 2009).", "Therefore, it is plausible that different pools of mTORC2 can be found within the cell.", "Pharmacological inhibition of PDK1 has been reported to have a profound effect on the activity of several AGC kinases such as RSK, S6K, PKC, and SGK (Najafov et al., 2011).", "However, in order to achieve the same inhibitory effects on AKT, higher doses of PDK1 inhibitors must be used.", "This is explained by the fact that AKT can be efficiently activated by PDK1 through PIP3-independent and PIF binding pocket-dependent mechanisms, leading to resistance to PDK1 inhibitors (Najafov et al., 2012).", "In our experiments using endogenous immunoprecipitated SGK1 and AKT1, we show that this is indeed the case in our model.", "In the presence of BYL719, SGK1 but not AKT remains active; conversely, upon GSK2334470 treatment, SGK1 but not AKT is fully inhibited.", "Single activity of any of these kinases seems to be sufficient to propagate downstream pro-survival signaling through mTORC1 activation and FOXO3 repression.", "This is also confirmed by the fact that the combination of both agents efficiently inhibits FOXO3 and mTORC1, inducing antitumor effects in cancer cells.", "In this setting, rather than inhibition of AKT, NDRG1 phosphorylation (substrate of both AKT and SGK1) should be used as readout of pathway inhibition (Kobayashi et al., 1999).", "Some evidence also suggests that SGK3 may play an important role in the oncogenicity of PI3K-driven cells.", "Our results indicate that this is not the case in intrinsic resistance to PI3K pathway inhibitors since low levels of SGK1, but not SGK2 or SGK3, are correlated with sensitivity to BYL719 (FIG.", "4) and AKT inhibitors (Sommer et al., 2013).", "Moreover, SGK3 is a direct downstream target of class III phosphoinositide 3-kinase and is indirectly inactivated upon class I PI3K inhibitor treatment (Bago et al., 2014), so it is an unlikely mediator of intrinsic resistance.", "In summary, our findings show that SGK1 mediates resistance to PI3Kα inhibitors through the activation of mTORC1, which can be reverted by PDK1 blockade.", "This study highlights the importance of understanding the underlying mechanisms of protein kinase regulation in

preparing a chemically prepared toner wherein a silane is surface treated on the outer surface of the core shell toner.", "The silane is surface treated on the outer surface of the toner using a sol-gel technique in situ, in particular a hydrolytic deposition process.", "This silane surface treatment on the outer surface of the toner changes the surface energy of the toner thereby generating an improved toner, particularly at hot and high humidity environments.", "Description of the Related Art Toners for use in electrophotographic printers include two primary types, mechanically milled toners and chemically prepared toners (CPT).", "Chemically prepared toners have significant advantages over mechanically milled toners including better print quality, higher toner transfer efficiency and lower torque properties for various components of the electrophotographic printer such as a developer roller, a fuser belt and a charge roller.", "The particle size distribution of CPTs is typically narrower than the particle size distribution of mechanically milled toners.", "The size and shape of CPTs are also easier to control than mechanically milled toners.", "One process for preparing a CPT is by emulsion aggregation.", "Emulsion aggregation is carried out in an aqueous system resulting in good control of both the size and shape of the toner particles.", "The toner components typically include a polymer binder, one or more colorants and a release agent.", "Electrophotographic printers typically use either a single component or a dual component development system.", "In a dual component development system, magnetic particles, or carriers, typically based on a manganese-ferrite core are combined with toner particles in what is called a developer mix.", "The magnetic particles are also used to charge the toner particles in a triboelectric manner.", "The normal triboelectric charge exchange between toner particles and the magnetic carriers is moderated by the moisture content in air.", "Thus, one measure of toner or developer mix performance is its ability to exhibit excellent charge stability and in particular exhibit charge stability in high temperatures and high humidity environments.", "Additionally, toner charge can diminish when the developer mix is not being stirred in a toner reservoir, due to charge exchange (i.e.", "neutralization or “relaxation”) between the toner particles and carrier while at rest.", "If the charge is not maintained at an adequate level, the toner particles can no longer be contained in toner reservoir due to the forces normally applied by electric fields.", "Under the influence of these forces, the toner exits in a cloud of toner particles suspended in air, commonly referred to as toner fuming or toner dusting.", "Toner dusting and fuming negatively effects print quality.", "The inventors of the present invention have discovered that by surface treating and bonding the outer surface of the toner particle with certain hydrocarbonsilane or a combination of hydrocarbonsilanes, the surface energy of the toner can be changed.", "This change in the toner's surface energy positively affects the charge stability of the toner, particularly at hot and high humidity environments.", "However to successfully change the surface energy of the toner particle, this silane must bond on the outer surface of the toner shell resin and cannot be embedded inside the outer shell resin of the toner.", "Unfortunately many surface treatments result in the embedding of the silane into the toner's shell, thereby negating any positive effect from the silane surface treatment.", "Moreover, it is difficult to bond a silane onto the outer surface of the toner particle through direct interaction such as Van der Waals forces, because the hydrophobicity of the hydrocarbonsilane used as a successful surface treatment in this invention is different from the hydrophobicity of the functional groups found on the toner's surface.", "The inventors have found that by using a the sol-gel technique in situ, in particular a hydrolytic deposition process as the surface treatment, an alkyloxysilane can be used to interact with the functional groups found on the outer surface of the toner particle via the hydrolytic deposition.", "Hydrolytic deposition efficiently decreases the hydrophilicity of the toner surface, promotes the interacting and eventual bonding of the alkyloxysilane with the functional groups found on the outer surface of the toner.", "Exemplary alkyloxysilane include trialkoxysilanehydrocarbon, dialkoxysilanehydrocarbon, monoalkoxysilanehydrocarbon, tetraalkoxydisiloxanehydrocarbon, tetraalkyldisiloxanehydrocarbon and trisiloxanehydrocarbon.", "Exemplary

soluble in a given medium and capable of precipitation), pigments (which may be insoluble in a given medium) or a combination of the two.", "A colorant dispersion may be prepared by mixing the pigment in water with a dispersant.", "Alternatively, a self-dispersing colorant may be used thereby permitting omission of the dispersant.", "The colorant may be present in the dispersion at a level of about

present at less than or equal to about 15% by weight of the final toner formulation including all values and increments therebetween.", "The optional coupling agent used herein is borax (also known as sodium borate, sodium tetraborate, or disodium tetraborate).", "As used herein, the term borax coupling agent is defined as enabling the formation of hydrogen bonds between polymer chains which assists in the anchoring or binding of the polymer found in the shell onto the surface of the toner core containing the polymers or mixture of polymers, thereby helping to couple the shell to the outer surface of the toner core.", "The borax coupling agent bonds the shell to the outer surface of the core by forming hydrogen bonding between its hydroxyl groups and the functional groups present in the polymers utilized in the inventive toner formulation.", "Coupling agents have multivalent bonding ability.", "Borax differs from commonly used permanent coupling agents, such as multivalent metal ions (e.g., aluminum and zinc), in that its bonding is reversible.", "In the electrophotographic process, toner is preferred to have a low fusing temperature to save energy and a low melt viscosity (“soft”) to permit high speed printing at low fusing temperatures.", "However, in order to maintain the stability of the toner during shipping and storage and to prevent filming of the printer components, toner is preferred to be “harder” at temperatures below the fusing temperature.", "Borax provides cross-linking through hydrogen bonding between its hydroxy groups and the functional groups of the molecules it is bonded to.", "The hydrogen bonding is sensitive to temperature and pressure and is not a stable and permanent bond.", "For example, when the temperature is increased to a certain degree or stress is applied to the polymer, the bond will partially or completely break causing the polymer to “flow” or tear off.", "The reversibility of the bonds formed by the borax coupling agent is particularly useful in toner because it permits a “soft” toner at the fusing temperature but a “hard” toner at the storage temperature.", "The reversible borax coupling agent may be present in the range of about 0.1% to about 5.0% by weight of the total polymer binder in the toner including all values and increments therebetween, such as between 0.1% and 1.0%.", "The silane compounds used herein as surface treatments are organosilanes, in particular an alkoxysilane or siloxane is necessary to initiate the hydrolytic reaction with the functional groups on the toner surface.", "The hydrolytic deposition anchors the attachment of the hydrocarbonsilane to the outer surface of the toner.", "Through the alkoxy groups covalently bonded to the functional groups located on the surface of the toner particle, hydrocarbonsilanes interact with the outer surface of the toner to decrease the hydrophilicity of the toner and firmly bonds onto the outer surface of the toner.", "The hydrocarbon group thus modifies the properties of the toner particle surface including, but not limited to, hydrophobicity, charge stability, surface energy, dielectric properties, and absorption properties.", "Both of the alkoxy and hydrocarbon functional groups can also exist in one molecule and function as the hydrolytic deposition and hydrophobicity modification on the toner surface.", "Silanes may be selected from a group including, but not limited to, methoxysilanes, ethoxysilanes, siloxanes, disiloxanes, trisiloxanes, trimethoxysilanehydrocarbons,

toner tribocharge, particularly at high humidity environments.", "Toner charge can also diminish when the developer mix is not being stirred in a toner reservoir.", "Each toner formulation was mixed with magnetic carrier particles to create a developer mix.", "The developer mix contained 8% of toner by mass, and the remainder (92%) of magnetic carrier particles.", "The toner and carrier were combined in a blender for sufficient time to assure good distribution of the toner onto the surfaces of the carrier particles.", "A total of ˜290 grams of the developer mix was then loaded into a toning station, and placed into a test fixture which simulated the operation of a developer unit in an electrophotographic printer, by means of a drive motor which rotated at the same speed as motors in the printer.", "The test fixture was placed in a test chamber, at 78° F. and 80% relative humidity to increase any tendency of the toner to dust.", "The toner tribocharge was measured initially, once again after the toning station had been operated for a time period that simulated the processing of 10,000 sheets, and for a final time after leaving the developer mix in the toning station overnight in the test chamber after processing the 10,000 sheets.", "The toner tribocharge was measured in an Epping q/m meter based on a known toner mass.", "The tribocharge results are shown in Table 1.Toner dust was evaluated using a paper strip placed over the mouth of the developer roll in the toning station.", "The motor used to rotate the toning station was operated for 20 seconds while the paper strip was in place to cause any dust coming from the developer unit during operation to deposit onto the paper surface.", "Then the paper strip was removed and inspected.", "Dusting strips were visually evaluated and then measured for a change in paper darkness using a spectrophotometer to measure print lightness (L*).", "The spectrophotometer results are shown in Table 1.Lower L* values indicate a darker paper strip due to more visible dusting on the strip.", "A clean or unused paper strip has a measured L* value of 96.Values below 90 produce a visually noticeable “band” of toner along the length of the paper strip.", "This is not a desirable result.", "Toner dust affects print quality and also can negatively affect the life of other components within an electrophotographic printer.", "A visual inspection of the amount of dusting on the hardware components in the toning station was observed at 0, 1,000, 5,000 and 10,000 simulated sheet intervals, and

simulated processing, even though the loss in tribocharge for 10,000 simulated sheets was greater for the Example Toner A.", "More importantly, the silane treated Example Toner A exhibited less tribocharge loss compared to the Control Toner after being left overnight—ΔQt was 12.73 (μC/g).", "As previously mentioned, the toner tribocharge diminishes when the developer mix is at rest, and accordingly, minimizing this loss is desirable.", "This retention of tribocharge when the developer mix is at rest corresponds to the significantly less dust on the paper strip for Example Toner A as compared to the Control Toner.", "After 10,000 simulated pages, Example Toner A had practically no dusting compared to the Control Toner which had a visible deposit of toner on the paper strip.", "After being left overnight, the Example A Toner had a very light deposit of toner on the strip, but the Control Toner had deposited a significant amount of toner onto the paper strip, as shown by a very low L* value of 52.6.As shown in Table 2, Example Toner A also performed better and exhibited less dusting on hardware components than the Control Toner.", "While the Control Toner already exhibited Moderate dusting after 10K pages, the Example Toner A only exhibited Light to Moderate dusting.", "This is desirable as it would mean less interference on other printer components due to toner dust.", "The foregoing description of several embodiments of the present disclosure has been presented for purposes of illustration.", "It is not intended to be exhaustive or to limit the

communication system using multiple antennas.", "In multi-antenna communication, of which MIMO is typical, multiple transmission signals are each modulated, and each modulated signal is simultaneously transmitted from a different antenna in order to increase the transmission speed of the data.", "FIG.", "23 illustrates a sample configuration of a transmission and reception device having two transmit antennas and two receive antennas, and using two transmit modulated signals (transmit streams).", "In the transmission device, encoded data is interleaved, the interleaved data is modulated, and frequency conversion and the like are performed to generate transmission signals, which are then transmitted from antennas.", "In this case, the scheme for simultaneously transmitting different modulated signals from different transmit antennas at the same timestamp and on a common frequency is spatial multiplexing MIMO.", "In this context, Patent Literature 1 suggests using a transmission device provided with a different interleaving pattern for each transmit antenna.", "That is, the transmission device from FIG.", "23 should use two distinct interleaving patterns performed by two interleavers (πa and πb).", "As for the reception device, Non-Patent Literature 1 and Non-Patent Literature 2 describe improving reception quality by iteratively using soft values for the detection method (by the MIMO detector of FIG.", "23).", "As it happens, models of actual propagation environments in wireless communications include NLOS (Non Line-Of-Sight), typified by a Rayleigh fading environment, and LOS (Line-Of-Sight), typified by a Rician fading environment.", "When the transmission device transmits a single modulated signal, and the reception device performs maximal ratio combination on the signals received by a plurality of antennas and then demodulates and decodes the resulting signals, excellent reception quality can be achieved in a LOS environment, in particular in an environment where the Rician factor is large.", "The Rician factor represents the received power of direct waves relative to the received power of scattered waves.", "However, depending on the transmission system (e.g., a spatial multiplexing MIMO system), a problem occurs in that the reception quality deteriorates as the Rician factor increases (see Non-Patent Literature 3).", "FIGS.", "24A and 24B illustrate an example of simulation results of the BER (Bit Error Rate) characteristics (vertical axis: BER, horizontal axis: SNR (signal-to-noise ratio) for data encoded with LDPC (low-density parity-check) codes and transmitted over a 2×2 (two transmit antennas, two receive antennas) spatial multiplexing MIMO system in a Rayleigh fading environment and in a Rician fading environment with Rician factors of K=3, 10, and 16 dB.", "FIG.", "24A gives the Max-Log approximation-based log-likelihood ratio (i.e., Max-log APP, where APP is the a posteriori probability) BER characteristics without iterative phase detection (see Non-Patent Literature 1 and Non-Patent Literature 2), while FIG.", "24B gives the Max-log APP BER characteristic with iterative phase detection (see Non-Patent Literature 1 and Non-Patent Literature 2) (number of iterations: five).", "FIGS.", "24A and 24B clearly indicate that, regardless of whether or not iterative phase detection is performed, reception quality degrades in the spatial multiplexing MIMO system as the Rician factor increases.", "Thus, the problem of reception quality degradation upon stabilization of the propagation environment in the spatial multiplexing MIMO system, which does not occur in a conventional single-modulation signal system, is unique to the spatial multiplexing MIMO system.", "Broadcast or multicast communication is a service that must be applied to various propagation environments.", "The radio wave propagation environment between the broadcaster and the receivers belonging to the users is often a LOS environment.", "When using a spatial multiplexing MIMO system having the above problem for broadcast or multicast communication, a situation may occur in which the received electric field strength is high at the reception device, but in which degradation in reception quality makes service reception impossible.", "In other words, in order to use a spatial multiplexing MIMO system in broadcast or multicast communication in both the NLOS environment and the LOS environment, a MIMO system that offers a certain degree of reception quality is desirable.", "Non-Patent Literature 8 describes a method of selecting a codebook used in precoding (i.e.", "a precoding matrix, also referred to as a precoding weight matrix) based on feedback information from a communication party.", "However, Non-Patent Literature 8 does not at all disclose a method for precoding in an environment in which feedback information cannot be acquired from the other party, such as in the above broadcast or multicast communication.", "On the other hand, Non-Patent Literature 4 discloses a method for switching the precoding matrix over time.", "This method is applicable when no feedback information is available.", "Non-Patent Literature 4 discloses using a unitary matrix as the precoding matrix, and switching the unitary matrix at random, but does not at all disclose a method applicable to degradation of reception quality in the above-described LOS environment.", "Non-Patent Literature 4 simply recites hopping between precoding matrices at random.", "Obviously, Non-Patent Literature 4 makes no mention whatsoever of a precoding method, or a structure of a precoding matrix, for remedying degradation of reception quality in a LOS environment.", "An object of the present invention is to provide a MIMO system that improves reception quality in a LOS environment.", "Embodiments of the present invention are described below with reference to the accompanying drawings.",

electrophotography and more particularly to a formulation and method for preparing a chemically prepared toner wherein a silane is surface treated on the outer surface of the core shell toner.", "The silane is surface treated on the outer surface of the toner using a sol-gel technique in situ, in particular a hydrolytic deposition process.", "This silane surface treatment on the outer surface of the toner changes the surface energy of the toner thereby generating an improved toner, particularly at hot and high humidity environments.", "Description of the Related Art Toners for use in electrophotographic printers include two primary types, mechanically milled toners and chemically prepared toners (CPT).", "Chemically prepared toners have significant advantages over mechanically milled toners including better print quality, higher toner transfer efficiency and lower torque properties for various components of the electrophotographic printer such as a developer roller, a fuser belt and a charge roller.", "The particle size distribution of CPTs is typically narrower than the particle size distribution of mechanically milled toners.", "The size and shape of CPTs are also easier to control than mechanically milled toners.", "One process for preparing a CPT is by emulsion aggregation.", "Emulsion aggregation is carried out in an aqueous system resulting in good control of both the size and shape of the toner particles.", "The toner components typically include a polymer binder, one or more colorants and a release agent.", "Electrophotographic printers typically use either a single component or a dual component development system.", "In a dual component development system, magnetic particles, or carriers, typically based on a manganese-ferrite core are combined with toner particles in what is called a developer mix.", "The magnetic particles are also used to charge the toner particles in a triboelectric manner.", "The normal triboelectric charge exchange between toner particles and the magnetic carriers is moderated by the moisture content in air.", "Thus, one measure of toner or developer mix performance is its ability to exhibit excellent charge stability and in particular exhibit charge stability in high temperatures and high humidity environments.", "Additionally, toner charge can diminish when the developer mix is not being stirred in a toner reservoir, due to charge exchange (i.e.", "neutralization or “relaxation”) between the toner particles and carrier while at rest.", "If the charge is not maintained at an adequate level, the toner particles can no longer be contained in toner reservoir due to the forces normally applied by electric fields.", "Under the influence of these forces, the toner exits in a cloud of toner particles suspended in air, commonly referred to as toner fuming or toner dusting.", "Toner dusting and fuming negatively effects print quality.", "The inventors of the present invention have discovered that by surface treating and bonding the outer surface of the toner particle with certain hydrocarbonsilane or a combination of hydrocarbonsilanes, the surface energy of the toner can be changed.", "This change in the toner's surface energy positively affects the charge stability of the toner, particularly at hot and high humidity environments.", "However to successfully change the surface energy of the toner particle, this silane must bond on the outer surface of the toner shell resin and cannot be embedded inside the outer shell resin of the toner.", "Unfortunately many surface treatments result in the embedding of the silane into the toner's shell, thereby negating any positive effect from the silane surface treatment.", "Moreover, it is difficult to bond a silane onto the outer surface of the toner particle through direct interaction such as Van der Waals forces, because the hydrophobicity of the hydrocarbonsilane used as a successful surface treatment in this invention is different from the hydrophobicity of the functional groups found on the toner's surface.", "The inventors have found that by using a the sol-gel technique in situ, in particular a hydrolytic deposition process as the surface treatment, an alkyloxysilane can be used to interact with the functional groups found on the outer surface of the toner particle via the hydrolytic deposition.", "Hydrolytic deposition efficiently decreases the hydrophilicity of the toner surface, promotes the interacting and eventual bonding of the alkyloxysilane with the functional groups found on the outer surface of the toner.", "Exemplary alkyloxysilane include trialkoxysilanehydrocarbon, dialkoxysilanehydrocarbon, monoalkoxysilanehydrocarbon, tetraalkoxydisiloxanehydrocarbon, tetraalkyldisiloxanehydrocarbon and trisiloxanehydrocarbon.", "Exemplary functional groups located on the outer surface of the toner particle include carboxyl and hydroxyl groups.", "This successful

cores reach a predetermined size.", "The second polymer emulsion is combined and agglomerated with the toner cores to form toner shells around the toner cores.", "The toner cores and toner shells are then fused to form toner particles.", "The silane solution is added dropwise to the fully formed core shell toner mixture and well stirred overnight, resulting in a silane surface treated core shell

hydroxyl groups and the functional groups present in the polymers utilized in the inventive toner formulation.", "Coupling agents have multivalent bonding ability.", "Borax differs from commonly used permanent coupling agents, such as multivalent metal ions (e.g., aluminum and zinc), in that its bonding is reversible.", "In the electrophotographic process, toner is preferred to have a low fusing temperature to save energy and a low melt viscosity (“soft”) to permit high speed printing at low fusing temperatures.", "However, in order to maintain the stability of the toner during shipping and storage and to prevent filming of the printer components, toner is preferred to be “harder” at temperatures below the fusing temperature.", "Borax provides cross-linking through hydrogen bonding between its hydroxy groups and the functional groups of the molecules it is bonded to.", "The hydrogen bonding is sensitive to temperature and pressure and is not a stable and permanent bond.", "For example, when the temperature is increased to a certain degree or stress is applied to the polymer, the bond will partially or completely break causing the polymer to “flow” or tear off.", "The reversibility of the bonds formed by the borax coupling agent is particularly useful in toner because it permits a “soft” toner at the fusing temperature but a “hard” toner at the storage temperature.", "The reversible borax coupling agent may be present in the range of about 0.1% to about 5.0% by weight of the total polymer binder in the toner including all values and increments therebetween, such as between 0.1% and 1.0%.", "The silane compounds used herein as surface treatments are organosilanes, in particular an alkoxysilane or siloxane is necessary to initiate the hydrolytic reaction with the functional groups on the toner surface.", "The hydrolytic deposition anchors the attachment of the hydrocarbonsilane to the outer surface of the toner.", "Through the alkoxy groups covalently bonded to the functional groups located on the surface of the toner particle, hydrocarbonsilanes interact with the outer surface of the toner to decrease the hydrophilicity of the toner and firmly bonds onto the outer surface of the toner.", "The hydrocarbon group thus modifies the properties of the toner particle surface including, but not limited to, hydrophobicity, charge stability, surface energy, dielectric properties, and absorption properties.", "Both of the alkoxy and hydrocarbon functional groups can also exist in one molecule and function as the hydrolytic deposition and hydrophobicity modification on the toner surface.", "Silanes may be selected from a group including, but not limited to, methoxysilanes, ethoxysilanes, siloxanes,

monoethoxysilanehydrocarbons, tetraalkoxydisiloxanehydrocarbons and tetraalkylldisiloxanehydrocarbons.", "Although longer chain length silanes are preferred to facilitate the strong interaction and bonding with the toner surface, the chain length must not be too long because longer chain lengths are difficult to disperse in aqueous system and therefore will negatively increase the toner processing.", "Exemplary silanes used have a chain length between 8 and 18 carbons.", "An embodiment uses a combination of 1,3-di-n-octyltetramethyldisiloxane and diethoxydimethylsilane for the chosen combination of silanes to be surface treated on the outer surface of the toner particle using a hydrolytic deposition process.", "Alternative embodiments use a silane such as n-octyltrimethoxysilane,

the toner charge.", "If the charge is not maintained at an adequate level, the toner particles become susceptible to forces exerted by electric fields, and thus more readily become suspended in air.", "Since the charge exchange between toner particles and magnetic carrier particles is moderated by the moisture content in the air, one measure of toner performance is the ability to maintain adequate toner tribocharge, particularly at high humidity environments.", "Toner charge can also diminish when the developer mix is not being stirred in a toner reservoir.", "Each toner formulation was mixed with magnetic carrier particles to create a developer mix.", "The developer mix contained 8% of toner by mass, and the remainder (92%) of magnetic carrier particles.", "The toner and carrier were combined in a blender for sufficient time to assure good distribution of the toner onto the surfaces of the carrier particles.", "A total of ˜290 grams of the developer mix was then loaded into a toning station, and placed into a test fixture which simulated the operation of a developer unit in an electrophotographic printer, by means of a drive motor which rotated at the same speed as motors in the printer.", "The test fixture was placed in a test chamber, at 78° F. and 80% relative humidity to increase any tendency of the toner to dust.", "The toner tribocharge was measured initially, once again after the toning station had been operated for a time period that simulated the processing of 10,000 sheets, and for a final time after leaving the developer mix in the toning station overnight in the test chamber after processing the 10,000 sheets.", "The toner tribocharge was measured in an Epping q/m meter based on a known toner mass.", "The tribocharge results are shown in Table 1.Toner dust was evaluated using a paper strip placed over the mouth of the developer roll in the toning station.", "The motor used to rotate the toning station was operated for 20 seconds while the paper strip was in place to cause any dust coming from the developer unit during operation to deposit onto the paper surface.", "Then the paper strip was removed and inspected.", "Dusting strips were visually evaluated and then measured for a change in paper darkness using a spectrophotometer to measure print lightness (L*).", "The spectrophotometer results are shown in Table 1.Lower L* values indicate a darker paper strip due to more visible dusting on the strip.", "A clean or unused paper strip has a measured L* value of 96.Values below 90 produce a visually noticeable “band” of toner along the length of the paper strip.", "This is not a desirable result.", "Toner dust affects print quality and also can negatively affect the life of other components within an electrophotographic printer.", "A visual inspection of the amount of dusting on the hardware components in the toning station was observed at 0, 1,000, 5,000 and 10,000 simulated sheet intervals, and the results are reported in Table 2.TABLE 1 Dusting Toner charge, Qt (μC/g) Over- Strip (L*) 10,000 0-10,000 night 10,000 (over- ΔQt ΔQt (over- 0 10,000 night) (μC/g) (μC/g) 10,000 night) Example

Very light Light Light Control Toner — Light Light to Moderate Moderate As shown in Table 1, the Control Toner exhibited lower tribocharge levels than Example Toner A, both initially and during simulated processing, even though the loss in tribocharge for 10,000 simulated sheets was greater for the Example Toner A.", "More importantly, the silane treated Example Toner A exhibited less tribocharge loss compared to the Control Toner after being left overnight—ΔQt was 12.73(μC/g).", "As previously mentioned, the toner tribocharge diminishes when the developer mix is at rest, and accordingly, minimizing this loss is desirable.", "This retention of tribocharge when the developer mix is at rest corresponds to the significantly less dust on the paper strip for Example Toner A as compared to the Control Toner.", "After 10,000 simulated pages, Example Toner A had practically no dusting compared to the Control Toner which had a visible deposit of toner on the paper strip.", "After being left overnight, the Example A Toner had a very light deposit of toner on the strip, but the Control Toner had deposited a significant amount of toner onto the paper strip, as shown by a very low L* value of 52.6.As shown in Table 2, Example Toner A also performed better and exhibited less dusting on hardware components than the Control Toner.", "While the Control Toner already exhibited Moderate dusting after 10K pages, the Example Toner A only exhibited Light to Moderate dusting.", "This is desirable as it would mean less interference on other printer components due to toner dust.", "The foregoing description of several embodiments of the present disclosure has been presented for purposes of illustration.", "It is not intended to be exhaustive or to limit the present disclosure to the precise forms disclosed, and obviously many modifications and variations are possible in light of the above teaching.", "It is intended that the scope of the present

variants of the cleaning wire element; and FIG.", "10 is an enlarged half-sectional view that shows the main valve seat with an additional sealing edge.", "DETAILED DESCRIPTION The structure and the basic operation of the process medium-controlled regulating valve will be described first for easier understanding of the invention with use of FIGS.", "1 to 3.For reasons of clarity, a cleaning wire 3 guided through a pilot line 1 and a helical compression spring 41 disposed in a control chamber 5 are omitted in FIGS.", "1 to 3 and shown only in FIGS.", "4 and 5.The regulating valve shown in FIG.", "1 comprises a main valve 11 (FIG.", "2), with which a liquid throughflow between an inlet chamber 13 and an outlet chamber 15 can be regulated, and a pilot valve 17 controlling main valve 11 (FIG.", "3), which can be used as a control component for main valve 11.Main valve 11 shown in FIG.", "1 is made up of a main valve piston 21, with an adjustable stroke in the axial direction in a valve housing 19, and of a main valve seat 23 which interacts therewith.", "In FIG.", "1, main valve piston 21 is shown in its open position, as a result of which a valve gap 25 is exposed for throughflow regulation.", "Inlet chamber 13 is disposed radially outside the hollow cylindrical main valve seat 23, whereas outlet chamber 15 is located radially inside main valve seat 23.Main valve piston 21 is designed in two parts in FIG.", "1, specifically, with a lower elastic membrane 27 to which a membrane plate 29, which is rigid in comparison thereto, is attached.", "Membrane 27 is fixed radially on the outside on valve housing 19.Control chamber 5 is located on the side of main valve piston 21, which side faces away from main valve seat 23 in the axial direction.", "This is fluidically connected via pilot line 1, integrated in main valve piston 21, to inlet chamber 13 and via a pressure relief line 31 to outlet chamber 15.In addition, pilot valve 17 (FIG.", "3) has a pilot valve piston 33, which is manually stroke-adjustable in the axial direction, specifically, in accordance with FIG.", "1, either by means of a pushbutton 35 or alternatively with the aid of a rotary knob 37.In FIG.", "1, pilot valve piston 33 is guided centrally through pressure relief line 31 in main valve piston 21.Depending on the manual actuation of the regulating valve, pilot valve piston 33 can be shifted between a closed position and an open position as well as into a regulating intermediate position.", "In FIG.", "1, pilot valve piston 33 is shown in its open position, in which pressure relief line 31 is opened.", "A pressure equalization results in this way between control chamber 5 and outlet chamber 15.Accordingly, in FIG.", "1 or 2, main valve piston 21, as shown, is moved upward in an opening direction due to the water pressure present in inlet chamber 13.As is apparent from FIG.", "4, in addition, a helical compression spring 41 is disposed in control chamber 5, which spring extends concentrically around pilot valve piston 33 and is supported between main valve piston 21 and an axially opposite valve housing wall 43.Further variants of cleaning wire 3 are shown in FIGS.", "6 to 9.Thus, in FIG.", "6 cleaning wire 3 does not have a round profile but a square profile.", "To increase the scraping properties, the square profile is spirally twisted.", "In FIG.", "7, cleaning wire 3 is spirally wound on its wire body 49.As in the previous embodiments, the adjoining free wire end 45 is formed straight with a continuously constant wire cross section.", "In FIG.", "8, cleaning wire 3 has a wave profile 53 on its wire body 49.The wave height of wave profile 53 increases in the direction of pilot line opening 47 facing inlet chamber 13.In FIG.", "9, the free wire end 45 is no longer straight but with an angled loop 55.A further exemplary embodiment is shown in FIG.", "10 which is to be regarded as an alternative to the preceding exemplary embodiments or forms a refinement thereof.", "Thus, according to FIG.", "10, main valve seat 23 has a sealing surface 57 facing main valve piston 21, which is divided in two, specifically, into a planar base surface 59, transverse to the axial direction, and a sealing edge 61 projecting in the direction of main valve piston 21.Sealing edge 61 is disposed radially on the inside and base surface 59 radially on the outside.", "Base surface 59 acts as a movement stop for limiting the stroke movement of main valve piston 21.As an alternative to the variant shown in FIG.", "10, sealing edge 61 can also be disposed radially on the outside and base surface 59 radially on the inside.", "Furthermore, when viewed in the radial direction, sealing edge 61 can also be disposed centrally, i.e., be bounded both radially on the outside and radially on the inside by planar base surface 59.The invention being thus described, it will be obvious that the same may be varied in many ways.", "Such variations are not to be regarded as a departure from the spirit and scope of the invention, and all such modifications as would be obvious to one skilled in the art are to be included within the scope of the following claims." ] ]

138.When the circuit board 59 is seated in the housing shell 58, the shell post 57 extends through opening 138.Control module 40 is first assembled by press fitting pins 75 into cap bores 90 of outer retaining cap 76.More particularly, the pin stem first portions 84 are press fit in cap bores 90 so that the remaining portions of the pin stems extend out through bosses 92.Active seals 79 are then inserted over the pin stem second portions 85.Outer retaining cap 76 is then press fit to the lower panel 53 of shell 58 so that bosses 92 seat in shell bores 69.Each active seal 79 is fitted in the associated shell bore 69 so that, as seen in FIG.", "8, the free ends of the boot skirts 124 and 126 are directed towards the adjacent outer retainer cap boss 92.When each seal is so positioned, the spring 130 simultaneously causes boot skirt 124 to press against the pin stem second portion 85 and boot skirt 126 to press against the inner circular wall of the shell 58 that defines the bore 69.Each seal 79 thus functions as a substantially gas-tight seal between each pin 75 and the surrounding portion of the shell bore 69.The inner retainer cap 77 is then fit over the inner face of the shell lower panel 53 and the pins 75.Owing to the relative dimension of the pins 75 and boss bores 95, the cap bosses 94 initially are slip fit over the pin third shaft section 86.Then, the cap bosses 94 are simultaneously press fit into the lower panel openings 69 and over the pin second shaft section 85.The components forming seal assembly 56 are further configured, so that when assembled, the active seals 79 are not compressed between the opposed cap bosses 92 and 94.Instead, even with seals 79 disposed in a bore 69, there is space within each shell bore 69 for the active seal 79 to move

module step 102.O-ring 62 is seated in the post groove 65.Lid 60 is then fitted over the open end of shell 58.Owing to the dimensioning of the components, there is a close slip fit between the outer surface of each lid rib 73 and 74 and the inner surface of, respectively, the adjacent side panel 52 and 51.The clearance between each rib 73 and 74 and adjacent side panel may be approximately 0.05

Loctite.", "The fastener is inserted through lid bore 72 and threaded into shell post bore 97.When tightened, the fastener 55 presses the lid 60 against the shell 58.As a result of this movement, O-ring 61 is compressed between the shell step 102 and the lid rim 104.O-ring 62 is compressed between the shell post groove 65 and the face of lid boss 70 so that lid boss 70 provides a face seal.", "As a consequence of the compression of the O-rings 61 and 62, the O-rings form substantially gas-tight seals between the module housingforming shell 58 and lid 60.The assembled control module 40 is then inserted into handle void space 29.Keys 67 and 68 serve as spacers to ensure the control module 40 is properly positioned in the handle 38.Key 68 also serves to transfer heat generated by the internal electrical components of control module 40.Heat dissipated from the shell 58 transfers through key 68 and into the handle 38.Fasteners, not illustrated, hold the control module 40 to the

the desired medical/surgical procedure.", "Once tool 30 is used, the tool can be autoclave sterilized like a conventional tool.", "In this process, the tool is placed in a sealed chamber into which saturated steam is introduced at temperatures up to 135° C. and pressures as high as 305,000 Pa absolute.", "During this process, the highly pressured steam presses against the outside of the module housing.", "A 686 mm of Mercury vacuum is then drawn on the handpiece.", "The seal-forming O-rings 61 and 62 prevent essentially any leakage of the highly pressurized steam into the control module 40.During the steam pressurization cycle, the pressurized steam presses inwardly on the structural members of the module housing, shell panels 51-54 and 63, and lid 60.The differential pressures between the inside and outside of the module housing results in the inward flexing of the housing panels, especially the lid 60 and the shell base panel 63.This inward flexing of the lid 60 is opposed by the abutment of the shell post 57 against the lid.", "During the vacuum drawing cycle, the differential pressure results in the outward flexing of the panels forming the housing.", "This outward flexing of the lid 60 is opposed by the ribs 73 and 74 and the fastener 55.The inhibiting of this outward flexing of the shell 58 and the lid 60 reduces the displacement of the lid 60 away from outer O-ring 61 and the breaking of the seal established by the lid-against O-ring contact.", "During sterilization, the seals 79 function as substantially gas-tight barriers between the bore 69 defining walls of the shell lower panel 53 and pins 75.It should be appreciated that during the sterilization process, the module shell 58 and pins 75 undergo some thermal expansion.", "Thermal coefficients of expansion of the materials forming module shell 58 and pins 75 are different.", "Pin 75 has a lower thermal coefficient of expansion than the surrounding shell 58.Consequently, there is an increase in the width of the annular gap between each pin 75 and surrounding shell wall.", "In response to this change, each seal spring 130 pushes the adjacent boot skirts 124 and 126 outwardly away from each other.", "Thus, each seal 79 maintains the barrier between the shell 58 and associated pin 75 during this portion of the autoclave process.", "Also during this portion of the autoclave process, a fraction of the pressurized steam may flow into the annular space between each pair of seal skirts 124 and 126.This pressurized steam thus functions as a second force that pushes the skirts 124 and 126 outwardly away from each other so as to further enhance the tightness of the substantially gas-tight seal.", "Even with this deformation of the boot 120, skirt 124 still abuts pin 75 and skirt 126 still abuts the surrounding inner wall of the shell lower panel 53.Each seal 79 therefore maintains a barrier around the pin 75 over which the seal is seated.", "Further, this deformation of the seal also means that thermal expansion of the shell 58 and pin 75 are not opposed by any forces that could impose fracture-inducing stresses on these components.", "During this process, the outward pushing of the seal skirts 124 and 126 away from each other causes a lengthening of the skirts.", "The skirts are able to expand into the clearance space in the bore 69 between cap bosses 92 and 94.This ability of the skirts 124 and 126 to freely expand allows the boots 120 to maintain their integrity.", "Once tool 30 is sterilized, the tool is removed from the autoclave.", "The temperature of the tool returns back to ambient levels.", "At this time, shell 58 and pins 75 undergo thermal contraction.", "In response to the decreasing in size of these components, the width of the annular gap between each pin 75 and the surrounding shell wall decreases.", "This causes a like decrease in the distance between the boot skirts 124 and 126.Each spring 130 is therefore subject to some radial compression.", "Owing to their flexible nature, springs 130 are able to undergo this compression without plastically mechanically deforming.", "Consequently, each spring 130 is still able to impose force on the associated boot that holds the skirts 124 and 126 away from each other.", "Springs 130 are thus able to supply the forces needed to maintain seals around pins 75 as the tool is, over time, subjected to plural autoclave sterilizations.", "Tool 30 of this invention has a control module with sets of seals able to withstand the rigors of repeated autoclave sterilization.", "O-rings 61 and 62 stop steam from entering between the module 40 between the shell 58 and lid 60.Due to the same material used in forming shell 58 and lid 60, creating equal coefficients of thermal expansion, O-rings are able to be used.", "Seal assembly 56 blocks steam from entering the control module 40 through shell bores 69.Both these sets of seals are relatively economical to provide.", "Further, shell 58 and lid 60 have features, shell post 57 and lid ribs 73 and 74 that inhibit the flexing of the control module housing when the tool 30 is pressurized during sterilization.", "By increasing the stiffness of the lid 60, the risk of having the seal broken is reduced.", "Another benefit of tool 30 of this invention over a tool with a control module that is brazed or welded closed is that it is possible to easily open module 40.This is accomplished by unscrewing fastener 55 and then removing lid 60.Thus, one could periodically remove the lid 60 from the shell 58.This process can be performed in a very dry (low humidity) work environment in order to facilitate the evaporation of any water that may have worked itself into the module housing.", "The components internal to the module can be inspected to determine if there is any evidence of potentially failure-inducing corrosion.", "Prior to resecuring of the lid 60 to the shell 58, the housing can be provided with new O-rings 61 and 62.Thus, unlike some present control modules, the control module of this invention is designed to allow preventive maintenance and repair.", "This can avoid the more costly process of having to periodically provide the tool with a completely new control module.", "II.", "Alternative Embodiments The above description is directed to one version of the invention.", "Other versions of the invention may have features different from what has been described.", "For example, there is no requirement that all versions of the invention contain both the described seal assembly 56 and O-rings 61 and 62.Other versions of this invention may only have a single one of the features.", "In some versions of the invention, the O-rings 61 and/or 62 may be replaced with an active seal similar to active seal 79.Each active seal would have a boot sized to fit between where the cover and lid would otherwise abut.", "Internal to the boot is one or more biasing components similar to seal spring 130 that exert a force on the boot skirts.", "These active seals would be similar in shape and size to the O-rings 61 and 62.These active seals would provide the function of the active seal 79 in the location of current O-rings 61 and 62.In other versions of the invention, O-rings 61 and/or 62 may be replaced with a gasket or a material similarly capable of establishing a substantially gas-tight seal between the structural members of the control module.", "The seal function performed by both O-rings 61 and 62 may be performed by a single piece of an elastomeric material.", "This piece of elastomeric material is positioned so as to extend between both the shell rim-to-lid interface and the post-to-lid interface.", "In these as well as other embodiments of the invention, it may not be necessary to provide the module shell with an inwardly directed step against which the rim-to-lid seal seats.", "Thus, in these versions of the invention, the rim-to-lid seal may directly abut the outer most face of the shell rim.", "In alternative versions of the invention, components other than the cap bosses may serves as the stops that prevent longitudinal movement of the active seals out of the module panel in which they are seated.", "There is no requirement that a plurality of cap bosses for either the inner retaining cap or outer retaining cap extend from a common plate.", "In these versions of the invention, associated with each active seal, are an inner stop and an outer stop.", "Neither of these stops are connected to any of the other stops that may be fitted to the common module panel.", "This is especially true in versions of the invention in which the conductive pins that extend through the control module are either widely spaced apart from

to refer to like elements throughout.", "In the following description, for purposes of explanation, numerous details are set forth in order to provide a thorough understanding of the various embodiments.", "It is evident, however, that the various embodiments can be practiced without these details (and without applying to any particular networked environment or standard).", "To provide network connectivity to additional base station devices, the backhaul network that links the communication cells (e.g., microcells and macrocells) to network devices of the core network correspondingly expands.", "Similarly, to provide network connectivity to a distributed antenna system, an extended communication system that links base station devices and their distributed antennas is desirable.", "A guided wave communication system can be provided to enable alternative, increased or additional network connectivity and a waveguide coupling system can be provided to transmit and/or receive guided wave (e.g., surface wave) communications on a wire, such as a wire that operates as a single-wire transmission line (e.g., a utility line), that operates as a waveguide and/or that otherwise operates to guide the transmission of an electromagnetic wave.", "In an embodiment, a waveguide coupler that is utilized in a waveguide coupling system can be made of a dielectric material, or other low-loss insulator (e.g., Teflon, polyethylene and etc.", "), or even be made of a conducting (e.g., metallic, non-metallic, etc.)", "material, or any combination of the foregoing materials.", "Reference throughout the detailed description to “dielectric waveguide” is for illustration purposes and does not limit embodiments to being constructed solely of dielectric materials.", "In other embodiments, other dielectric or insulating materials are possible.", "It will be appreciated that a variety of transmission media can be utilized with guided wave communications without departing from example embodiments.", "Examples of such transmission media can include one or more of the following, either alone or in one or more combinations: wires, whether insulated or not, and whether single-stranded or multi-stranded; conductors of other shapes or configurations including wire bundles, cables, rods, rails, pipes; non-conductors such as dielectric pipes, rods, rails, or other dielectric members; combinations of conductors and dielectric materials; or other guided wave transmission media.", "For these and/or other considerations, in one or more embodiments, an apparatus comprises a waveguide that facilitates propagation of a first electromagnetic wave at least in part on a waveguide surface, wherein the waveguide surface does not surround in whole or in substantial part a wire surface of a wire, and, in response to the waveguide being positioned with respect to the wire, the first electromagnetic wave couples at least in part to the wire surface and travels at least partially around the wire surface as a second electromagnetic wave, and wherein the second electromagnetic wave has at least one wave propagation mode for propagating longitudinally along the wire.", "In another embodiment, an apparatus comprises a waveguide that has a waveguide surface that defines a cross sectional area of the waveguide wherein a wire is positioned outside of the cross-sectional area of the waveguide such that a first electromagnetic wave, traveling along the wire at least in part on the wire surface, couples at least in part to the waveguide surface and travels at least partially around the waveguide surface as a second electromagnetic wave.", "In an embodiment, a method comprises emitting, by a transmission device, a first electromagnetic wave that propagates at least in part on a waveguide surface of a waveguide, wherein the waveguide is not coaxially aligned with a wire.", "The method can also include configuring the waveguide in proximity of the wire to facilitate coupling of at least a part of the first electromagnetic wave to a wire surface, forming a second electromagnetic wave that propagates longitudinally along the wire and at least partially around the wire surface.", "In another embodiment, an apparatus comprises, in one or more embodiments, a waveguide having a slot formed by opposing slot surfaces that are non-parallel, wherein the opposing slot surfaces are separated by a distance that enables insertion of a wire in the slot, wherein the waveguide facilitates propagation of a first electromagnetic wave at least in part on a waveguide surface, and, in response to the waveguide being positioned with respect to the wire, the first electromagnetic wave couples at least in part to a wire surface of the wire and travels at least partially around the wire surface as a second electromagnetic wave for propagating longitudinally along the wire, and wherein the second electromagnetic wave has at least one wave propagation mode.", "In another embodiment, an apparatus comprises, in one or more embodiments, a waveguide, wherein the waveguide comprises a material that is not electrically conductive and is suitable for propagating electromagnetic waves on a waveguide surface of the waveguide, wherein the waveguide facilitates propagation of a first electromagnetic wave at least in part on the waveguide surface, and, in response to the waveguide being positioned with respect to a wire, the first electromagnetic wave couples at least in part to a wire surface of the wire and travels at least partially around the wire surface as a second electromagnetic wave, and wherein the second electromagnetic wave has at least one wave propagation mode for propagating longitudinally along the wire.", "One embodiment of the subject disclosure includes an apparatus having a waveguide that facilitates transmission or reception of electromagnetic waves along a wire surface of a wire of a power grid that also facilitates delivery of electric energy to devices.", "The apparatus can further include one or more sensors that facilitate sensing of a disturbance that is adverse to the waveguide, the wire, the transmission or reception of electromagnetic waves that propagate along the wire surface or waveguide surface, or any combination thereof.", "One embodiment of the subject disclosure includes a method for transmitting, by an apparatus having a waveguide and a sensor, electromagnetic waves that propagate along a wire surface of a wire that facilitates delivery of electric energy to devices, and sensing, by the sensor, a disturbance that is adverse to the electromagnetic waves that propagate along the wire surface.", "One embodiment of the subject disclosure includes a machine-readable (e.g., computer-readable, processor-readable, etc.)", "storage medium having executable instructions that, when executed by a processor, facilitate performance of operations, including inducing with or via a waveguide, electromagnetic waves guided along a surface of a transmission medium, and collecting sensing data from a sensor, the sensing data associated with a disturbance that is adverse to the electromagnetic waves guided along the surface of the transmission medium.", "One embodiment of the subject disclosure includes an apparatus having a processor and a memory.", "The processor can perform an operation of receiving telemetry information from a waveguide system coupled to a sensor, detecting from the telemetry information a disturbance that is adverse to one of operations of the waveguide system, the transmission or reception of the electromagnetic waves along the wire surface or the waveguide surface, or a combination thereof, and reporting the disturbance.", "The waveguide system can comprise a waveguide that can be positioned with respect to a wire of a power grid that facilitates delivery of electric energy to devices.", "The waveguide can also facilitate transmission or reception of electromagnetic waves along a wire surface of the wire, while the sensor can facilitate sensing disturbances adverse to electromagnetic waves.", "One embodiment of the subject disclosure includes a method for receiving, by a network element comprising a processor, telemetry information from a waveguide system, determining, by the network element, a disturbance from sensing data included in the telemetry information, and transmitting, by the network element, instructions to the waveguide system to adjust a route of the electromagnetic waves to avoid or compensate for the disturbance determined.", "The waveguide system can facilitate transmission of electromagnetic waves along a wire surface of a wire of a power grid and sensing of disturbances adverse to the transmission or reception of the electromagnetic waves.", "One embodiment of the subject disclosure includes a machine-readable (e.g., computer-readable, processor-readable, etc.)", "storage medium having executable instructions that, when executed by a processor, facilitate performance of operations, including receiving telemetry information from an apparatus that induces electromagnetic waves on a wire surface of a wire of a power grid for delivery of communication signals to a recipient communication device coupled to the power grid, and detecting a disturbance from the telemetry information that is adverse to a delivery of the communication signals to the recipient communication device.", "One embodiment of the subject disclosure includes an apparatus including a satellite receiver, a processor, and a memory that stores executable instructions.", "When the instructions are executed by the processor, the processor can perform operations including receiving content from the satellite receiver, encoding the content according to a satellite distribution protocol that facilitates satellite switching to generate satellite encoded content, formatting the satellite encoded content according to an internet protocol (IP) to generate IP formatted content, and submitting the IP formatted content to a gateway of a plurality of gateways for distribution of at least a portion of the IP formatted content to a plurality of set-top boxes over a wireline communication network.", "One embodiment of the subject disclosure includes an apparatus including a satellite receiver, a processor, and a memory that stores executable instructions.", "When the instructions are executed by the processor, the processor can perform operations including receiving content from the satellite receiver, encoding the content according to a satellite distribution protocol that facilitates satellite switching to generate satellite encoded content, formatting the satellite encoded content according to an internet protocol (IP) to generate IP formatted content, and submitting the IP formatted content over a wireline communication network to a gateway of a plurality of gateways for distribution of at least a portion of the IP formatted content to a plurality of set-top boxes.", "One embodiment of the subject disclosure includes a method for receiving satellite signals from a satellite system, processing the satellite signals to retrieve media channels, each comprising digital content, selecting a portion of the media channels for redistribution to a plurality of set-top boxes remotely located from a distribution device, encoding the portion of the media channels selected for redistribution according to a satellite distribution protocol that facilitates satellite switching to generate satellite encoded content, formatting the satellite encoded content according to an internet protocol (IP) to generate IP formatted content, and providing the IP formatted content to a gateway for distribution of at least a portion of the IP formatted content to the plurality of set-top boxes over a communication network.", "One embodiment of the subject disclosure includes a machine-readable storage medium, having executable instructions that, when executed by a processor of a distribution device, facilitate performance of operations, including receiving decoded satellite signals, obtaining media channels from the decoded satellite signals, each media channel comprising digital content, selecting a portion of the media channels for distribution to a plurality of media processors remotely located from the distribution device, encoding the portion of the media channels selected according to a satellite distribution protocol to generate satellite encoded content, formatting the satellite encoded content according to a transport protocol to generate formatted content, and providing the formatted content for distribution to the plurality of media processors via a communication network.", "In an example embodiment, the transport protocol can differ from the satellite distribution protocol.", "In another embodiment, the communication network comprises a portion of a power grid that transports the formatted content as electromagnetic waves that propagate along surfaces of power lines of the power grid.", "Various embodiments described herein relate to a waveguide coupling system for launching and extracting guided wave (e.g., surface wave communications that are electromagnetic waves) transmissions from a wire.", "At millimeter-wave frequencies (e.g., 30 to 300 GHz), wherein the wavelength can be small compared to the size of the equipment, transmissions can propagate as waves guided by a waveguide, such as a strip or length of dielectric material or other coupler.", "The electromagnetic field structure of the guided wave can be inside and/or outside of the waveguide.", "When this waveguide is brought into close proximity to a wire (e.g., a utility line or other transmission line), at least a portion of the guided waves decouples from the waveguide and couples to the wire, and continue to propagate as guided waves, such as surface waves about the surface of the wire.", "According to an example embodiment, a surface wave is a type of guided wave that is guided by a surface of the wire, which can include an exterior or outer surface of the wire, or another surface of the wire that is adjacent to or exposed to another type of medium having different properties (e.g., dielectric properties).", "Indeed, in an example embodiment, a surface of the wire that guides a surface wave can represent a transitional surface between two different types of media.", "For example, in the case of a bare or uninsulated wire, the surface of the wire can be the outer or exterior conductive surface of the bare or uninsulated wire that is exposed to air or free space.", "As another example, in the case of insulated wire, the surface of the wire can be the conductive portion of the wire that meets the insulator portion of the wire, or can otherwise be the insulator surface of the wire that is exposed to air or free space, or can otherwise be any material region between the insulator surface of the wire and the conductive portion of the wire that meets the insulator portion of the wire, depending upon the relative differences in the properties (e.g., dielectric properties) of the insulator, air, and/or the conductor and further dependent on the frequency and propagation mode or modes of the guided wave.", "According to an example embodiment, guided waves such as surface waves can be contrasted with radio transmissions over free space/air or conventional propagation of electrical power or signals through the conductor of the wire.", "Indeed, with surface wave or guided wave systems described herein, conventional electrical power or signals can still propagate or be transmitted through the conductor of the wire, while guided waves (including surface waves and other electromagnetic waves) can propagate or be transmitted about the surface of the wire, according to an example embodiment.", "In an embodiment, a surface wave can have a field structure (e.g., an electromagnetic field structure) that lies primarily or substantially outside of the line, wire, or transmission medium that serves to guide the surface wave.", "According to an example embodiment, the electromagnetic waves traveling along the wire and around the outer surface of the wire are induced by other electromagnetic waves traveling along a waveguide in proximity to the wire.", "The inducement of the electromagnetic waves can be independent of any electrical potential, charge or current that is injected or otherwise transmitted through the wires as part of an electrical circuit.", "It is to be appreciated that while a small current in the wire may be formed in response to the propagation of the electromagnetic wave along the wire, this can be due to the propagation of the electromagnetic wave along the wire surface, and is not formed in response to electrical potential, charge or current that is injected into the wire as part of an electrical circuit.", "The electromagnetic waves traveling on the wire therefore do not require a circuit to propagate along the wire surface.", "The wire therefore is a single wire transmission line that is not part of a circuit.", "Also, in some embodiments, a wire is not necessary, and the electromagnetic waves can propagate along a single line transmission medium that is not a wire.", "According to an example embodiment, the term “about” a wire used in conjunction with a guided wave (e.g., surface wave) can include fundamental wave propagation modes and other guided waves having a circular or substantially circular field distribution (e.g., electric field, magnetic field, electromagnetic field, etc.)", "at least partially around a wire or other transmission medium.", "In addition, when a guided wave propagates “about” a wire or other transmission medium, it can do so according to a wave propagation mode that includes not only the fundamental wave propagation modes (e.g., zero order modes), but additionally or alternatively other non-fundamental wave propagation modes such as higher-order guided wave modes (e.g., 1st order modes, 2nd order modes, etc.", "), asymmetrical modes and/or other guided (e.g., surface) waves that have non-circular field distributions around a wire or other transmission medium.", "For example, such non-circular field distributions can be unilateral or multi-lateral with one or more axial lobes characterized by relatively higher field strength and/or one or more nulls or null regions characterized by relatively low-field strength, zero-field strength or substantially zero field strength.", "Further, the field distribution can otherwise vary as a function of a longitudinal axial orientation around the wire such that one or more regions of axial orientation around the wire have an electric or magnetic field strength (or combination thereof) that is higher than one or more other regions of axial orientation, according to an example embodiment.", "It will be appreciated that the relative positions of the wave higher order modes or asymmetrical modes can vary as the guided wave travels along the wire.", "Referring now to FIG.", "1, a block diagram illustrating an example, non-limiting embodiment of a guided wave communication system 100 is shown.", "Guided wave communication system 100 depicts an exemplary environment in which a dielectric waveguide coupling system can be used.", "Guided wave communication system 100 can comprise a first instance of a distributed system 150 that includes one or more base station devices (e.g., base station device 104) that are communicably coupled to a central office 101and/or a macrocell site 102.Base station device 104 can be connected by a wired (e.g., fiber and/or cable), or by a wireless (e.g., microwave wireless) connection to the macrocell site 102 and the central office 101.A second instance of the distributed system 160 can be used to provide wireless voice and data services to mobile device 122 and to residential and/or non-residential/commercial establishments 142 (herein referred to as establishments 142, which can include homes, businesses, or other permanent or semi-permanent structures).", "System 100 can have additional instances of the distribution systems 150 and 160 for providing voice and/or data services to mobile devices 122-124 and establishments 142 as shown in FIG.", "1.Macrocells such as macrocell site 102 can have dedicated connections to the mobile network and base station device 104 can share and/or otherwise use macrocell site 102′s connection.", "Central office 101 can be used to distribute media content and/or provide internet service provider (ISP) services to mobile devices 122-124 and establishments 142.The central office 101 can receive media content from a constellation of satellites 130 (one of which is shown in FIG.", "1) and distribute such content to mobile devices 122-124 and establishments 142 via the first and second instances of the distribution system 15 and 160.The central office 101 can also be communicatively coupled to the Internet 103 for providing internet data services to mobile devices 122-124 and establishments 142.Base station device 104 can be mounted on, or attached to, utility pole 116.In other embodiments, base station device 104 can be near transformers and/or other locations situated nearby a power line.", "Base station device 104 can facilitate connectivity to a mobile network for mobile devices 122 and 124.Antennas 112 and 114, mounted on or near utility poles 118 and 120, respectively, can receive signals from base station device 104 and transmit those signals to mobile devices 122 and 124 over a much wider area than if the antennas 112 and 114 were located at or near base station device 104.It is noted that FIG.", "1 displays three utility poles, in each instance of the distribution systems 150 and 160, with one base station device, for purposes of simplicity.", "In other embodiments, utility pole 116 can have more base station devices, and more utility poles with distributed antennas and/or tethered connections to establishments 142.A dielectric waveguide coupling device 106 can transmit the signal from base station device 104 to antennas 112 and 114 via utility or power line(s) that connect the utility poles 116, 118, and 120.To transmit the signal, radio source and/or coupler 106 upconverts the signal (e.g., via frequency mixing) from base station device 104 or otherwise converts the signal from the base station device 104 to a millimeter-wave band signal and the dielectric waveguide coupling device 106 launches a millimeter-wave band wave that propagates as a guided wave (e.g., surface wave or other electromagnetic wave) traveling along the utility line or other wire.", "At utility pole 118, another dielectric waveguide coupling device 108 receives the guided wave (and optionally can amplify it as needed or desired or operate as a digital repeater to receive it and regenerate it) and sends it forward as a guided wave (e.g., surface wave or other electromagnetic wave) on the utility line or other wire.", "The dielectric waveguide coupling device 108 can also extract a signal from the millimeter-wave band guided wave and shift it down in frequency or otherwise convert it to its original cellular band frequency (e.g., 1.9 GHz or other defined cellular frequency) or another cellular (or non-cellular) band frequency.", "An antenna 112 can transmit (e.g., wireles sly transmit) the downshifted signal to mobile device 122.The process can be repeated by dielectric waveguide coupling device 110, antenna 114 and mobile device 124, as necessary or desirable.", "Transmissions from mobile devices 122 and 124 can also be received by antennas 112 and 114 respectively.", "Repeaters on dielectric waveguide coupling devices 108 and 110 can upshift or otherwise convert the cellular band signals to millimeter-wave band and transmit the signals as guided wave (e.g., surface wave or other electromagnetic wave) transmissions over the power line(s) to base station device 104.Media content received by the central office 101 can be supplied to the second instance of the distribution system 160 via the base station device 104 for distribution to mobile devices 122 and establishments 142.The dielectric waveguide coupling device 110 can be tethered to the establishments 142 by one or more wired connections or a wireless interface.", "The one or more wired connections, may include without limitation, a power line, a coaxial cable, a fiber cable, a twisted pair cable, or other suitable wired mediums for distribution of media content and/or for providing internet services.", "In an example embodiment, the wired connections from the waveguide coupling device 110 can be communicatively coupled to one or more very high bit rate digital subscriber line (VDSL) modems located at one or more corresponding service area interfaces (SAIs—not shown), each SAI providing services to a portion of the establishments 142.The VDSL modems can be used to selectively distribute media content and/or provide internet services to gateways (not shown) located in the establishments 142.The SAIs can also be communicatively coupled to the establishments 142 over a wired medium such as a power line, a coaxial cable, a fiber cable, a twisted pair cable, or other suitable wired mediums.", "In other example embodiments, the waveguide coupling device 110 can be communicatively coupled directly to establishments 142 without intermediate interfaces such as the SAIs.", "In another example embodiment, system 100 can employ diversity paths, where two or more utility lines or other wires are strung between the utility poles 116, 118, and 120 (e.g., for example, two or more wires between poles 116 and 120) and redundant transmissions from base station 104 are transmitted as guided waves down the surface of the utility lines or other wires.", "The utility lines or other wires can be either insulated or uninsulated, and depending on the environmental conditions that cause transmission losses, the coupling devices can selectively receive signals from the insulated or uninsulated utility lines or other wires.", "The selection can be based on measurements of the signal-to-noise ratio of the wires, or based on determined weather/environmental conditions (e.g., moisture detectors, weather forecasts, etc.).", "The use of diversity paths with system 100 can enable alternate routing capabilities, load balancing, increased load handling, concurrent bi-directional or synchronous communications, spread spectrum communications, etc.", "(See FIG.", "8 for more illustrative details).", "It is noted that the use of the dielectric waveguide coupling devices 106, 108, and 110 in FIG.", "1 are by way of example only, and that in other embodiments, other uses are possible.", "For instance, dielectric waveguide coupling devices can be used in a backhaul communication system, providing network connectivity to base station devices.", "Dielectric waveguide coupling devices can be used in many circumstances where it is desirable to transmit guided wave communications over a wire, whether insulated or not insulated.", "Dielectric waveguide coupling devices are improvements over other coupling devices due to no contact or limited physical and/or electrical contact with the wires that may carry high voltages.", "With dielectric waveguide coupling devices, the apparatus can be located away from the wire (e.g., spaced apart from the wire) and/or located on the wire so long as it is not electrically in contact with the wire, as the dielectric acts as an insulator, allowing for cheap, easy, and/or less complex installation.", "However, as previously noted conducting or non-dielectric couplers can

herein relate to forming on a substrate fastener elements suitable for use in touch fastener.", "The processes described provide for a greater flexibility in manufacturing than prior methods and overcome certain limitations in prior forming techniques.", "Further, the product made can embody a variety of different configurations suitable for a given application.", "In one aspect, employing vibrational forming methods (for example, ultrasonic forming methods) allows for the use of a wider variety of substrate material than materials used with convention methods of touch fastener formation.", "For example, the inventor has recognized that ultrasonic energy may be applied to previously formed substrates such that at least portions of the substrate may be formed with the desired fastener element.", "Forming fastener elements such as hook elements, or other projections suitable for use in a touch fastener, directly onto a portion of a pre-formed substrate may permit the completed product to retain the benefits of the material chosen for the substrate.", "In this regard, though not limited in this respect, the need to subsequently attach a separately formed touch fastener to an otherwise completed product (e.g., diaper) is avoided and the resulting product is able to retain its properties.", "For example, fastener elements may be formed onto a preformed elastomeric nonwoven substrate.", "The use of elastomeric substrate permits the mated closure to be flexible.", "In application on an infant diaper, this flexibility may be desirable because it can minimize irritation to the infant often caused by conventional, overly rigid touch fasteners (e.g., such as might be the case where a separately formed touch fastener component is subsequently attached to the diaper).", "Further, though not limited in this respect, forming the fastener element directly on to the product may result in reduced inventory, reduced post-processing (e.g., where the touch fastener must be subsequently applied to the product), increased production speed, and lower manufacturing cost.", "Accordingly, in addition to conventional materials/configurations, other substrate materials and/or configurations may now be employed, such as woven or non-woven substrates; knitted substrates; foam substrates; substrates incorporating biodegradable components; substrates formed of or otherwise containing cellulosic material; substrates formed into screens or meshes; fabric substrates; film, sheet or web substrates; composite substrates containing one or more materials and/or configurations; laminate substrates (whether pre-formed or laminated during the vibrational formation process); substrates incorporating loops configured to mate with corresponding fastener elements; substrates containing other property modifying components, such as substrates with metallic wires or foils; reinforced substrates; substrates formed of or containing elastic or elastomeric materials; and substrates containing inextensible components.", "It should be appreciated that other materials may be included in the preformed substrate or introduced during the forming process.", "Such other materials and/or components include, but are not limited to, films, foams, wovens, nonwovens, metals, polymers, monofilaments, wire, static discharge materials, papers, fibers, adhesives (e.g., liquid, hot melt, or pressure sensitive adhesives), and powders.", "Such materials and/or components may be used to enhance the properties (e.g., strength, dielectric, temperature, etc.)", "of the substrate and/or formed fastener elements.", "Thus, a substrate may be any appropriate material or component for supporting fastener elements and/or providing material for forming fastener elements.", "According to another aspect, the use of vibration energy such as ultrasonic energy to form fastener elements allows for the application of certain desired patterns.", "In this regard, in addition to embodiments where the fastener elements are formed across the entire surface of the substrate, a single or multiple fastener elements may be formed at desired locations, for example in a checkerboard pattern, in rows or stripes, in circular, oval, annular, polygonal (square or rectangular) shapes or even in the pattern of a logo.", "In one embodiment, multiple fastener elements are formed on a patch of the substrate and multiple patches of the formed substrate (formed with the multiple fastener elements) are arranged in a desired pattern such as a checkerboard pattern of alternating formed and unformed patches.", "Other patterns may be employed, as aspects are not limited in this respect.", "Some of the fastener elements may be differently shaped than other fastener elements.", "Fastener elements may be formed on each surface of the substrate.", "Such patterning can provide some useful benefits.", "For example, the inventor has appreciated that there tends to be enhanced attachment along the leading and trailing edges of a field of fastener elements with its mating component.", "Accordingly, by forming the substrate with a plurality of fastener fields, there can be more leading and trailing edges of fastener elements (e.g., hooks) available for engagement with the mating component of a touch fastener (e.g., loops).", "The field may be aligned in an arc or at an angle relative to an edge of the substrate or in any other patterns as desired.", "The field may be formed such that it is spaced inward of the peripheral edge of the substrate providing a buffer zone at the edge, thereby reducing the stiffness of the edge.", "This may be particularly useful when forming the fastener elements on a diaper such as the material forming the diaper tab.", "The unaltered edge of the tab (that is, due to the inward formation of the fastener field) may aid in reducing irritation of the diaper tab against a baby's skin.", "It should be appreciated that the diaper tab may be a separate component that is subsequently attached to other portions of a diaper or the diaper tab may be an extension of a portion of the diaper, such as an extension of a side panel of the diaper.", "Thus, as used herein, the terms “diaper tab”, “diaper side tab”, “side tab” and “side panel” are used interchangeable to mean these alternative arrangements, unless specifically stated otherwise.", "Further, spacing fields of fastener elements apart from each other can render the component to be self-engaging where the substrate itself is suitable to mate with the fastener elements.", "In one embodiment, one or more fields of hook fastener may be vibrationally (e.g., ultrasonically) formed onto a preformed loop substrate, with the fastener being formed from the loop material itself.", "Once the hooks are formed onto the loop substrate, the substrate can be folded or layered onto itself such that the field of hooks engages with the adjacent loops.", "This is possible because the vibrational formation process allows for the formation of hooks onto a substrate that has been preformed as convention loop material.", "It should be appreciated that the hooks can be formed intermittently or in spaced apart fields of hooks such that spaced apart fields of loop material remains.", "Alternatively one entire area of the substrate may be formed into hooks that can then engage the adjacent loop material of the virgin or unaltered loop substrate.", "Further, it should be appreciated that the loop structure of the substrate may be on one surface of the substrate whereas the hook is formed on the opposite surface.", "This opposite surface may or may not have a loop structure.", "Also, the opposite surface may or may not be formed with hooks.", "In one or more of these embodiments, a first portion of the substrate containing the loop material is forced into mold cavities to produce fastening elements.", "That is, the loop material or loop structure itself is forced into mold cavities to form fastening elements on the otherwise loop substrate.", "Examples of a resulting product include diaper tabs, cable ties or wraps.", "Furthermore, the substrate material may be modified and/or enhanced so as to render the substrate more suitable to engage with the fasteners.", "For example, as will be explained in more detail below, the substrate material that is not vibrationally formed into fastener elements may be embossed using ultrasonic energy by depressing regions of the substrate.", "The embossing may cause the non-depressed regions to exhibit greater potential for engagement with the fasteners, by for example, standing proud of the depressed regions and thus more readily able to engage with the fasteners.", "For example, a non-woven substrate material having random fibers can be embossed such that at least some of the ends of the fibers are “welded” (i.e., “staked”) down by the embossment to create at least some loops with which to engage fastener elements.", "Vibrationally forming fastener elements on substrates may further provide enhanced performance of the fastener elements and/or the finished component.", "According to another aspect, the substrate may include one or more desired features.", "For example, the substrate may include or be formed with reinforcement features, such as ribs, bumps, creases or other structural configurations to selectively stiffen or reinforce the substrate or select areas thereof.", "Such reinforcement features may be formed adjacent to the fastener field or as part of the fastener element or elements to provide support to the fasteners.", "An elastomeric substrate may be stretched prior to the vibrational formation of the fastener elements.", "For example, the elastomeric substrate is stretched and then fastener elements are ultrasonically formed on the stretched substrate.", "Upon relaxing the substrate thereafter, the fastener elements are nestled closer together, resulting in a smoother tactile feel.", "For example, the top surfaces of the hooks, being closely spaced, allows the hooks to ride or glide over a person's skin such that the person is unable to feel (or feel only slightly) the terminal end of the hook, which might otherwise cause a pinching or scratching sensation.", "Upon stretching the substrate to engage a mating material or component, the field of fastener elements bloom, allowing the individual fastener elements to be able to engage with the mating component.", "Further, another benefit of employing an elastomeric substrate is that once the fastener elements are engaged, the relaxing of the substrate tends to cause the fastener elements to rake across the mating surface, thereby enhancing engagement.", "In addition or alternatively, the fastener elements may be formed in spaced apart fields on the stretched elastomeric substrate.", "When the substrate is thereafter in a relaxed state, the unaltered regions between the fastener fields tend to loft.", "This lofting may approach the height of the fastener elements and server to shield the fastener element from premature engagement.", "The lofted substrate may further improve the tactile feel of the product, reducing the perceived abrasiveness of the fastener elements.", "This too can be beneficial in applications such as on diapers (e.g., diaper tabs) where the fastener elements may otherwise cause an irritation on the baby's skin.", "It may be desirable to limit the amount of stretching of the substrate.", "Thus, the substrate may include or may be formed to include a tether that is joined to the substrate to limit the amount of extension upon stretching.", "Thus, a non-extensible strip or film of polymeric or other material may be incorporated into the substrate upon ultrasonic formation of the fastener elements.", "Outer suitable arrangements for limiting the stretch may be employed, as the present disclosure is not limited in this regard.", "For example, and as will be explained more fully below, the substrate may be formed with berms which may be placed in a zig-zag pattern.", "The berm may extend from the base of one fastener element to an adjacent fastener element.", "In one aspect, the inventor found that employing ultrasonics in the way described below can improve throughput of the formation process as compared to the process described in applicant's above-referenced patent.", "The inventor discovered that the maximum line speed of production may be limited by the available power of the ultrasonic generator.", "In one embodiment the throughput can be improved by minimizing the amount of substrate material that is heated by the ultrasonic generator.", "For example, the mold tool and/or surface of the ultrasonic tool that imparts energy to the substrate may be configured with a topology that concentrates the energy to where it is most needed.", "In one embodiment, forming such a surface may include forming the surface with spaced apart recesses surrounding the cavities which form the fastener elements.", "In this way, the energy from the ultrasonic generator is concentrated around the mold cavity where it is necessary so that the substrate material can enter the cavity.", "There is no need to apply energy to the area away from the mold cavity if the substrate material at that location is not needed for forming the projections.", "Such topography of the relevant surface(s) may also be configured to take into account any desired reinforcement to the substrate (e.g., reinforcement rib) and/or resulting fastener element.", "According to another aspect, line speed may be increased by preheating the substrate prior to the application of the vibration energy.", "The temperature of the substrate would be raised to below its melting point and the ultrasonic energy need only be sufficient to increase the temperature an additional amount (less than would be required without preheating) to allow the material to enter the mold cavities.", "Preheating the substrate can be performed in any number of ways, including but not limited to, using a heater immediately prior to the substrate being acted on by the vibrational energy source, bulk heating the substrate either in a separate oven or by employing a heated feed roller or feed chamber, etc.", "The heat may be convection (such as a hot air blower), radiant (such as heat lamps or filaments) or RF (radio frequency).", "The inventor has found that it may be desirable to enhance the properties (e.g., strength) of the substrate, as discussed above, which may be accomplished by applying an additive material to the substrate either during or prior to the applying the vibration.", "In addition, the inventor has found that it may be desirable to enhance the properties (e.g., strength) of the resulting fastener elements formed on the substrate.", "According to one aspect, materials with differing melt temperature or melt properties may be introduced before, during or after the formation.", "In one embodiment, the substrate itself may include multiple materials that behave differently at different processing temperatures.", "In another embodiment, a laminating material having material properties different than the substrate may be introduced before, during or after the formation.", "The inventor has found, by experimentation, that when a nonwoven substrate constructed with an elastomeric film embedded within the substrate was ultrasonically processed, the elastomeric film material (having different material properties, such as a different melt property, than the material of the nonwoven substrate) was softened and forced between the fibers of the nonwoven substrate and into the mold cavities.", "This resulted in hooks having elastomeric properties on the surface of the substrate.", "The nonwoven fibers of the substrate were minimally affected during the processing, with most fibers remaining predominately in the plane of the substrate.", "The inventor has also found, by experimentation, that when a polymer film with a lower melt temperature than the substrate material was introduced between the ultrasonic horn and the nonwoven substrate, the polymer film was softened, forced through the fibers of the nonwoven substrate and into the mold cavities, leaving the nonwoven fibers predominately in the plane of the substrate.", "Thus, the inventor has found that when producing product from mutilayered substrates, it is possible to selectively form the fastener elements from one or more of the layered materials within the substrate based on the material properties (e.g., melt properties, melt temperature, etc.)", "of a particular layer of material.", "The inventor also found that adding powdered material to the back of the substrate (i.e., the surface opposite to the mold cavities, that is opposite to where the fastener elements will be formed) or sprinkled onto the mold such that some of the powder enters the cavities may enhance the properties of the fastener elements.", "The inventor has found, by experimentation, that when powder was applied to the back surface of the substrate and the substrate was passed between a mold roll and ultrasonic device, the powder was distributed in the softened substrate and served to modify the properties of the substrate and of the formed projections.", "In one experiment conducted by the inventor, corn starch was dusted onto a substrate, specifically onto the back of a laminated nonwoven substrate having a top layer of polypro SMS (more formally known as polypropylene spunbonded melt blown spunbonded), a center layer of elastomeric film and a bottom layer of polypro SMS.", "The dusted SMS substrate was fed into the ultrasonic forming device to form hooks.", "The laminated substrate appeared unchanged while the formed hooks appeared to internally contain particles of corn starch.", "This corn starch served to stiffen the hooks, improving their fastening strength.", "In another experiment conducted by the inventor, the same substrate without the addition of corn starch had been used to ultrasonically form hooks and the inventor determined that the elastomeric center film softened before the SMS layers and filled the cavities producing an extremely soft hook element that may be too weak to serve as a fastener element.", "In another embodiment, the cavities may be filled or partially filled with a material including but not limited to a liquid material that may serve to reinforce any substrate material that is forced into the mold cavity.", "One such material may be a liquid or an adhesive-like material that may be applied in liquid form into the cavity before a nonwoven substrate is exposed to the vibrational energy.", "The adhesive-like material may saturate or coat any fibers that enter or partially enter a cavity and serve to stiffen or render more resilient the resultant fastener element (e.g., nook) formed during the ultrasonic processing of the fastener element.", "In one embodiment a water based adhesive, such as Elmer's® brand glue, is deposited into the cavities and a paper material is introduced between the mold and the vibrational energy source.", "A portion of the paper enters the cavities and the adhesive saturates or coats the fibers that enter the cavities, imparting improved properties to the resultant formed fastener elements.", "In some embodiments, it may be necessary to post-form the projections as the adhesive continues to dry and/or cure.", "Other substrate materials susceptible to at least partial wetting or saturation by the adhesive may also be employed.", "Accordingly, such additives applied to the substrate or to the cavities used to form the fastener elements may include, but is not limited to, powder materials, fiber materials, metal materials, liquids and adhesives, with such additives being applied prior to or during the formation of the fastener elements.", "According to another aspect, the inventor has found that in some instances there may not be a sufficient amount of substrate material available to form a complete fastener element by the ultrasonic forming process.", "In this regard, when forming fastener elements on a single layer of thin substrate material, there may be difficulty creating fully formed fastener elements due to the lack of material available adjacent to the cavity to fill the cavity during the ultrasonic formation process.", "During experiments conducted by the inventor, using a substrate of SMS material having a mass of 40 ft to 60 grams per square meter (which is currently being used by major diaper manufacturers), it was common to produce only partially formed hook elements.", "There was insufficient material available to fill cavities and yet have sufficient material to act as the substrate carrier for the hook elements.", "One way to avoid such a problem would be to reduce the cavity volume or quantity of cavities, though such a solution may not be an option where larger fastener elements or increased fastener field density is desired.", "Another solution may be to use a thicker substrate, but this may not be appealing from a cost point of view.", "Another solution may be to provide a supplemental material such as a film or nonwoven material, again resulting in increased cost and material handling complexity.", "The inventor has found that “gathering” a portion of the thin substrate immediately before it enters the nip between the mold and the ultrasonic horn can provide the necessary amount of material to appropriately fill the cavities when forming the fastener elements.", "Although the “gathering” may be done in the machine direction “MD” (that is the direction that the substrate is feed from a roll of substrate material through the ultrasonic forming process and collected downstream of the forming station) or the cross direction “CD” (that is, the direction transverse to the MD), gathering in the CD may be more preferable for diaper tab applications because the fastener area or field is typically a narrow field or lane running down the length of a wider substrate.", "By gathering the substrate in the CD direction, the extra material created by the gathering can be applied specifically to the lane where the fastener elements are to be formed.", "In one embodiment, material is gathered in a pleated fashion allowing the volume of substrate in the forming zone to be set as desired.", "In this regard, tighter pleats equates to more material available for forming the fastener elements.", "In one embodiment, a device may be used to channel the substrate in a way that forms the pleats.", "In addition or in the alternative, the leading edge of the ultrasonic device can have similar pleats to maintain the material in the desired location.", "Further, the pleats need not completely fold over onto themselves to provide a multilayered folded substrate; rather, the pleats may be formed with a frequency that does not result in overlapping the substrate material yet is sufficient to gather enough material to allow the fastener elements to be fully formed.", "One of the disadvantages of conventional molded hook touch fastener strip or component is the difficult in sewing onto another product.", "The molded touch fastener has a much lower tear resistance than the textile material it is attached to and so the touch fastener strip often tears away from the product when a load is applied.", "According to another aspect, utilizing vibrational energy to form fastener elements on a substrate may allow for greater ease of attaching the substrate to another product, such as clothing, luggage, etc.", "In this regard, assuming for some reason it is less desirable to form the fastener elements on the product itself, utilizing ultrasonic formation of the fastener elements such that the fastener elements are formed directly onto a textile or nonwoven substrate allows the resultant touch fastener strip to be readily sewn to another product.", "The projections may be intermittently formed on a sewable substrate in such a fashion so as to maintain the sewability of the substrate.", "If desired, additional patterns may be ultrasonically formed into the substrate to improve the tear resistance or enhance the sewability of the fastener strip so formed.", "Although the term “hook” or “hook element” is used herein when referring to a fastener element, it is understood that fastener elements are not limited to hook-like shapes and may be in the shape of mushrooms, tees, hooks, multi-lobed hooks, pins, projections or other shapes as desired.", "Such shapes may act as fastener elements as formed or may be post formed to make them suitable as a fastener for use in touch fastener.", "Further, the term “projection” or “pin” may refer to an element that by itself or through a post forming operation can function as a fastener element.", "Further, the terms “fastener element” and “fastening elements” are used interchangeably herein.", "“Loop” or “loop material” may include any structure or material that is suitable for mating with a fastener element, such as for example a hook element.", "The loop may be formed from a woven, nonwoven, foam, screen or mesh substrate or combinations thereof.", "“Elastomeric substrate” (such as, but not limited to, the kind described above) that is formed entirely or partially with elastomeric material in the form of fibers or films or may be a

energy source used to soften the substrate to from the fastener elements.", "In some embodiments, ultrasonic energy is described as the vibrational energy employed, though in those embodiments, one of skill would recognize that other forms of vibrational energy may be employed and thus the present disclosure is not limited in this regard.", "Turning now to the figures several non-limiting

embodiments, as shown in FIGS.", "1A-1D, hooks 19 of a fastening surface are depicted and may be located within at least a portion of a recess 23 of a substrate 21.In some cases, the hooks 19 are integrally formed on the surface (e.g., within the recess) of the substrate 21.As illustrated, the base 20 where the hook(s) 19 are attached to the substrate 21 may be located within a recess 23, spaced inward from the upper surface 22 of the substrate 21.The base 20 may include a fillet region, as shown.", "Again, to reemphasize, although hooks are depicted in this disclosure, other suitable

suitable height h. The height h of one or more hooks may reach from the base 20 of the hook(s) above, at or below the corresponding surface 22 of the substrate 21.For example, FIG.", "1A depicts an embodiment where the height h of the hooks 19 is sufficiently large such that the hooks 19 protrude or otherwise reach above the upper surface 22 of the substrate 21.Alternatively, FIG.", "1B shows an embodiment where the

a suitable method, for example, by impregnation, lamination and/or another appropriate method.", "FIGS.", "1B and 1C depict an embodiment where hooks 19 are formed within a recess 23 defined by an elastomeric non-woven substrate 21.In FIG.", "1B, the elastomeric substrate 21 is in a relaxed state, and in FIGS.", "1C, the elastomeric substrate 21 is in a stretched state.", "For certain embodiments, it may be preferable for the substrate material to be elastomeric or exhibit a greater degree of flexibility and/or elasticity than would otherwise be the case without the elastomeric material.", "This enhanced level of flexibility and/or elasticity may be desirable, for example, in a part of the diaper that is often handled and/or is subject to frequent motion.", "In some instances, it may be irritating for such portions of the diaper, which exhibit constant motion, to be overly rigid.", "When the elastomeric substrate 21 is in a relaxed state, such as that shown in FIG.", "1B, the substrate 21 may have a tendency to loft over and/or around the hooks 19, approaching the height of the hooks.", "Here, the hooks remain approximately at or below (or just slightly above) the upper surface 22 of the substrate 21.Accordingly, by not protruding upward above the substrate by a significant amount, the hooks may be effectively shielded by the substrate.", "In some embodiments, such shielding of the hooks may provide protection or otherwise limit physical exposure of the hooks, making them less prone to undesirable contact with other objects and/or incurring damage.", "In such cases, when the hooks are shielded from physical exposure with other objects, the overall surface of the material may exhibit a relatively smooth tactile feel, as compared to a more abrasive feel if the hooks protrude over the upper surface 22 of the substrate 21.That is, the abrasive tactile feel of the hooks is obstructed or otherwise reduced when the substrate is suitably lofted above the hooks.", "In some instances, it may be preferable for a product (e.g., diaper, garment, etc.)", "having fastening hooks formed thereon to exhibit a low level of abrasiveness, for example, when rubbed against the skin.", "Having the substrate lofted above the hooks may reduce the abrasiveness that would otherwise be felt.", "Such shielding may also limit or obstruct the hooks 19 from pre-mature engagement with corresponding fastener elements, such as loop structures.", "When the elastomeric substrate 21 is in a stretched state (e.g., pulled by a user along the depicted bold arrows), such as that shown in FIG.", "1C, the substrate may become thinner, as depicted, and the hooks 19, or other fastening elements, may bloom or otherwise extend over the upper surface 22 of the substrate by an amount sufficient to engage a mating fastening structure.", "Accordingly, when the elastomeric substrate is stretched, the hooks 19 may be suitably exposed and presented in a preferred orientation that facilitates engagement and/or attachment with one or more corresponding loops and/or other fastening elements.", "In some embodiments, when the substrate 21 is stretched, the hooks may extend further above the upper surface 22 of the substrate, or may remain at the same height h as compared to the height before stretching.", "In some embodiments, and as further shown in FIG.", "1C, stretching of the elastomeric substrate may also cause individual hooks to become more spread apart from one another.", "Hence, when the elastomeric substrate 21 is still in a stretched state (e.g., with respective hooks in a bloomed and spread apart state), the hooks 19 may be brought into contact with fastening elements that are suitably structured for mutual engagement.", "When in close enough proximity and/or contact with a surface having corresponding fastening elements, the elastomeric substrate may be released, resulting in the hooks retracting back toward a resting configuration, such as that shown in FIG.", "1B, where the substrate 21 becomes thicker and the hooks 19 become spaced closer together.", "This results in the hooks 19 latching and/or grasping on to the corresponding loops and/or other fastening elements in a more effective manner than would otherwise be the case if the elastomeric substrate were not stretched prior to mutual engagement.", "For example, allowing the individual hooks to be brought closer together upon release of the elastomeric substrate, while having latched on so the respective loops and/or other fastening elements.", "This raking of the hooks may strengthen the overall attachment between complementary materials.", "Also, lofting of the substrate such that the hooks, relatively speaking, retract back into the recess 23 of the substrate 21 may pull the loops and/or either fastening elements in toward the hooks, also resulting in a relatively strong attachment between complementary materials.", "In some embodiments, an elastomeric non-woven substrate 21 may be maintained in a stretched condition while patterns of fastening elements (e.g., hooks) are ultrasonically formed.", "Hence, when the substrate is allowed to retract after forming of the fastening elements thereon, the fastening elements may naturally shift closer together so as to increase the density of elements, while maintaining the ability of the substrate to be stretched as desired.", "This provides for a relatively dense field of fastening elements when the elastomeric substrate is in a resting, non-stretched suite.", "If the density of the field of fastening elements is high enough, when in a non-stretched state, the overall fastening surface may be relatively smooth to the touch.", "However, when the substrate is stretched, the density of the field of fastening elements may decrease, leading to a more abrasive tactile feel of the overall fastening surface.", "Though, as the substrate is released, if the hook elements are in mating contact with corresponding loop fields, the hooks may then exhibit a raking action, resulting in a relatively strong closure between mating surfaces.", "It can be appreciated that any suitable type of fastening element (e.g., hooks, loops, projections, pins, etc.)", "may be formed on any side of the substrate, according to any suitable arrangement.", "For example, as shown in FIG.", "1D, hooks may be formed on more than one side of the substrate.", "Here, hooks 19 are formed on opposite sides of the substrate 21.Accordingly, for this embodiment, a complementary material (e.g., having appropriate loops) may be attached on one or both sides of the substrate.", "As noted above, in some cases, loop portions may be constructed so as to be lofted relative to the hooks.", "Alternatively, or in combination, the substrate may be stretched during formation of the hooks, so that when the substrate is relaxed, the loop portions are able to loft to a greater extent toward and/or above the top of the hooks.", "The substrate may also be processed so as to provide a patterned arrangement of hooks, loops and/or other fastening elements on both the front and back surfaces.", "Accordingly, fastening strips may be mated to themselves and/or other fastening strips on the front and/or back surface, such as when used as a cable wrap.", "In some embodiments, the substrate may include one or more surfaces, or portions thereof, that may have hook and/or loop components.", "That is, rather than forming hooks or a single type of fastening element on an entire surface of a substrate,

directly on one or more surfaces that had previously included loop elements.", "That is, where the substrate may have originally had a region of loops and/or other elements, hooks and/or other fastening elements may be formed directly in their place.", "For instance, the original elements may be heated, melted, reshaped or otherwise reformed using methods in accordance with the present disclosure, to result in hooks and/or other types of fastening elements such that the fastener element is formed from the loop material itself.", "Accordingly, for some embodiments, hooks may be formed intermittently on one or more surfaces that had originally included only loops.", "Such a material thus formed, having both hook and loop structures, may be capable of mating to itself.", "For instance, forming hook elements on the back side of a substrate originally covered only with loops may allow the product to be wrapped around an object and engaged to itself.", "Also, the loop material or loop structure itself may be forced into mold cavities to form fastening elements on the otherwise loop substrate.", "Such a substrate with loops provided thereon may include any suitable material, such as a nonwoven, woven, textile, polymer, foam, fibrous material, other suitable materials, or combinations thereof.", "As noted above, a self-engaging fastener strip may be formed by selective patterning of hooks or hook fields directly onto a suitable elastomeric loop substrate.", "For example, hook fields may be patterned on a loop substrate in any suitable configuration.", "In some embodiments, hooks and loops may be formed in a checkerboard, striped and/or other patterned arrangement, which may allow for hooks and loops to be suitably available for mutual engagement when surfaces are mated face to face.", "That is, patterned surfaces with both hook and loop fields may be appropriately mated when brought together into mutual contact.", "In some embodiments, to achieve a strong attachment, it may be preferable for the surface of a touch fastener to include numerous leading and trailing edges where, when fastening products are peeled from one another, the leading edge is the edge of a field of fastening elements that is first removed, and the trailing edge is the last part of the field of fastening elements that is removed.", "It has been observed that when attaching hook and loop touch fasteners to one another, there tends to be improved engagement between fasteners along leading and trailing edges of a hook field.", "That is, the more leading and trailing edges there are between touch fasteners, the more difficult it may be to separate them from one another.", "Without wishing to be bound by theory, this may be due, at least in part, to the increased quantity of fastener elements engaged or readily engageable—that is, the fastener elements are not shielded by adjacent fastener elements and may be able to penetrate the mating material more easily.", "Fastening surfaces having more surface area may exhibit a greater ability to mutually engage as opposed to fastening surfaces having comparatively less surface area.", "Hence, the attachment between one surface that is formed entirely of hook elements and another surface formed entirely of loop elements may not be as strong as the attachment between two complementary surfaces each formed of a striped, checkerboard and/or other suitable arrangement of hook and loop fields.", "Or, in some embodiments it may be preferable to form an attachment between one surface formed of a striped or grid-like pattern of hook elements and another surface formed entirely of loop elements, or vice versa.", "By forming the fastener element in discrete patterns, such as rows/columns and/or patches, more leading and trailing edges may be made available for engagement between fastening surfaces, thus, providing a more secure attachment.", "FIG.", "2A shows an illustrative embodiment of a fastening surface having a striped pattern of hooks 19 formed directly on an elastomeric non-woven substrate 21.FIG.", "2A further shows the striped fields of hooks 19 separated from one another by edges 40a, 40b, with virgin substrate material located between stripes.", "As discussed above, these edges 40a, 40b may serve as leading and trailing edges for enhancing attachment between fastening surfaces.", "For example, the fastening surface having the striped pattern of hooks 19 formed from the elastomeric substrate 21 may form a relatively stronger attachment to a surface entirely of loops compared to an attachment between a fastening surface formed entirely of hooks 19 and a surface entirely of loops.", "In some cases, material processed to form hooks or other fastening elements may be formed to be relatively stiffer in comparison to the substrate material that has not yet been processed.", "That is, processed substrate material may be stiffer than non-processed substrate material.", "Thus, the remaining stripes of virgin substrate material may desirably provide an added degree of flexibility for the overall product.", "In one embodiment of a fastening surface, fastening elements are formed according to a patterned arrangement.", "In this embodiment, patches of hooks are formed on an elastomeric non-woven substrate material.", "In various embodiments, where elements are formed as an individual element and/or a patch of elements, the portion of the elastomeric non-woven material surrounding the element(s) may remain unaltered.", "This may, for example, allow for the formation of intermittent patches of hooks or other fastening elements directly on to the substrate material (e.g., material forming a diaper tab), optionally leaving a relatively bald perimeter area (e.g., of elastomeric non-woven material) around the hook field.", "This bald or unaltered perimeter may provide a relatively soft and low stiffness material which, in some cases, may limit marking and/or irritation for a user (e.g., wearer of a diaper, garment, etc.)", "of the fastening product.", "It can be appreciated that fastening elements may be patterned on to a substrate

15 may act as the vibrating source.", "In such embodiments, the vibration energy is directed or concentrated toward the portion(s) of the substrate material from which fastening elements are to be formed and the immediate surroundings.", "As a result, there is little to no waste of vibration energy on other portions of the substrate material which are not intended to be formed as fastening elements.", "It can be appreciated that contact regions and recesses of molds and/or vibrating sources may have any suitable characteristics and dimensions.", "The contact regions may be large enough to press against and cause an adequate amount of substrate material to fill into respective cavities.", "For instance, if the contact regions are too small, then an insufficient amount of substrate material may be operated upon for filling of the cavities.", "On the other hand, larger contact regions and smaller recesses might not be necessary for formation of the fastening elements, and could lead to manufacturing inefficiencies where ultrasonic energy is unnecessarily applied to certain portions of the substrate material.", "Further, the recesses may be structured to further limit the

ridges, fillets, rounds, bevels and/or other oriented features that may serve to guide material towards respective cavities, increasing the available amount of material for production.", "These structural features may also serve to provide support to individual fastening element enhancing their ability to resist loads applied from various directions.", "For example, the area around the formed fastening element may have been weakened or thinned during the forming process and thus the fastening element itself may not adequately resist the forces applied to it to hold onto the mating fasting element (which may occur due to the shear load placed on the fastening element).", "By forming structural enhancements such as reinforcement members, berms, ridges, etc., that may serve to link adjacent fastening elements, the fastening elements may better resists the shear loads applied to it.", "In one embodiment, as shown in FIG.", "2B, the berms 50 are formed so as to effectively link the factoring elements 19 side to side and front to back.", "Contact regions and recesses of the mold and/or vibrating source may also be arranged according to any suitable pattern.", "For instance, contact regions and recesses may be arranged for the formation of a small number of fastening elements (e.g., single cavity, few cavities within a contact region) and/or for larger numbers

possible to modify or enhance the performance of an existing loop or loop-like structure using ultrasonic energy applied to the substrate either while forming the fastener elements or before or afterward.", "For example, when applied to a non-woven substrate that may be marginal as a mating fastener (e.g., loop) material, a honeycomb surface pattern on the mold roll, located in regions of the mold roll where there are no fastener element (e.g.,) hook cavities, could serve to selectively compress and bond a non-woven substrate in such a fashion so as to create dots or patches of mating fastener that are more functional (e.g., by compressing the perimeter, a raised pillow of substrate material is formed, with such material being more readily snared by hooks than a flat surface of the substrate.", "A rib pattern may be utilised in lieu of a dot pattern.", "Indeed, other patterns may be employed, as the present disclosure is not limited in this respect.", "In one embodiment, the raised feature is formed at the same time that the fastener elements are formed.", "FIGS.", "10A and 10B show examples of such a touch fastener strip.", "The use of ultrasonic energy on the substrate can enable forming not only the fastener elements, but also enhance the complementary mating surface of the substrate.", "For example, the substrate 11 may be modified with vibration energy to produce depressed regions on the substrate resulting in raised embossments 70.That is, depressions are formed on the loop substrate so as to form spaced apart fields of loop structures, which may result in a honeycomb or honeycomb-like pattern or linear pattern of spaced apart fields of loop structures.", "As noted above, portions of the substrate may be gathered to increase the density of the substrate available for forming the embossments.", "The plurality of embossments 70 allow for the substrate material to stand proud of the substrate 11 such that the raised dimples 70 can more readily engage the hooks 19.In this regard, the multiple raised dimples provide multiple leading and trailing edges of the complementary mating material.", "This may be especially useful when the substrate is a non-woven material.", "In embodiments, as shown, where fields of fastener elements are formed adjacent fields of embossments, the touch fastener strip can be attached to itself when used as a wire or cable tie.", "Of course, the features (fasteners and mating features) can be formed on opposite sides of the substrate such that when the strip is coupled to itself around a cable or wire bundle, the fasteners can readily engage the mating features.", "As shown in FIG.", "10B, which is a top plan view of the touch fastener strip, the touch fastener strip may be formed such that adjacent fields are formed in an angular pattern.", "In this way, one end of the strip can engage the oppose end of the strip regardless of where the two come into contact with each other.", "Though the above is described with respect to a fastener strip, these concepts may be embodied on a diaper or portions of a diaper.", "It should be appreciated that the features described above can be formed in any suitable pattern, such as in a grid pattern or a honeycomb pattern.", "In one embodiment, as shown in FIGS.", "11A and 11B, a non-woven substrate material having random fibers can be embossed such that at least some of the ends of the fibers are “welded” (i.e., “staked”) down by the embossment to create adjacent lofted areas that can serve as loops with which to engage fastener elements.", "As shown in FIG.", "11A, a substrate 150 formed from a non-woven material (or having a non-woven layer) includes a plurality of fibers 152.The fibers are randomly oriented fibers intertwined and held relative to each other through friction.", "In some cases, the fibers may be loosely bonded together, as is known in the art of non-woven material formation.", "As illustrated, the fibers 152 have ends 154 with some of the ends 154 extending upward from the substrate whereas other fibers 152 are more embedded within the layer of the substrate itself.", "In either case, it may be difficult if not impossible for the mating fastener element (e.g., hook element) to engage with the fiber let alone hold to it to form a suitable touch fastener arrangement.", "That is, it may be difficult for a mating fastener element to reach down into the layers of fibers in order to grasp the fibers.", "Thus, in order to render the non-woven substrate more suitable for engagement with a mating fastener element, in one embodiment as illustrated in FIG.", "11B, the substrate 150 is embossed using the aforementioned ultrasonic forming technology.", "This embossing process effectively renders the substrate to be more three-dimensional rather than having a relatively flat upper surface, as shown in FIG.", "11A.", "That is, the embossment causes some of the fibers 152 to be raised proud of the substrate, enabling a mating fastener element to more readily engage the substrate material, as explained above by creating more leading and trailing edges of the field of engagement.", "In this regard, the embossment causes regions of the non-woven material adjacent the welded regions to become lofted.", "It should be appreciated that the embossment may be in any desired pattern, such as a checkerboard, a honeycomb pattern, a series of strips, a series of rounded pillows or any other shape that creates a patchwork of raised and staked land portions.", "In addition, the embossing process may cause at least some portions of the fibers (such as the two ends 154 of the fibers 152 or an end and a mid-section of the fibers or two spaced apart mid-sections of the fibers) to become staked (i.e., bonded) within welded regions 158 creating one or more raised loop structures 156.In some cases, the staking operation will tend to bond the fibers to a greater extent than found initially in the virgin state of the non-woven such that the resulting loop structures 156 are then capable of readily being engaged by the mating fastener elements and providing a more suitable holding force for the mating fastener without the fibers becoming decoupled from the substrate.", "In other words, the bond is a greater bond that in the virgin material.", "This bonding can also serve to enhance the structure integrity to the substrate by creating reinforced sections on the substrate, as explained above.", "In one embodiment, as shown in FIG.", "11C, the non-woven substrate 150 may be laminated to another material 160 that is formed with openings 162, such as a screen-like material.", "During the embossing process, the laminate of non-woven material 150 and laminating material 160 is staked as described above such that regions of the non-woven and the laminating material becomes lofted relative to the pinched areas 158.This creates a three-dimensional region with which to more readily receive the mating fastener element.", "That is the fastener element can more readily grasp the laminate material by entering the openings of the laminate, pushing the underlying non-woven material out of the way and then hooking/grasping on to portions of the laminate.", "In one embodiment, the underlying non-woven material aids in biasing the hook upward into engagement with the portions of the laminate.", "It should be appreciated that the fastener elements may be formed directly on an end-product or on a component of an end product.", "For example, the fastener elements may be formed directly on a diaper or on a diaper tab (which is then subsequently attached to the diaper or is an extension of the diaper side panel, etc.", "as explained above), as the present disclosure is not limited in this regard.", "Further, the complementary mating features may be formed on the diaper itself as well, creating a landing field for the fastener elements.", "While the present teachings have been described in communication with various embodiments and examples, it is not intended that the present teachings be limited to such embodiments or examples.", "On the contrary, the present teachings encompass various alternatives, modifications, and equivalents, as will be appreciated by those of skill in the art.", "Accordingly, the foregoing description and drawings are by way of

determining the level of demand for domain names.", "In one implementation, the present disclosure provides a method including the steps of receiving, by a server communicatively coupled to a network, a request from a requester.", "Using the request to identify a domain name and determining whether the domain name is registered.", "When the domain name is not registered, a search metric for the domain name is determined and a first user interface listing the domain name and the search metric is displayed.", "The first user interface enables the requester to purchase the domain name.", "In another implementation, the present disclosure provides a method including the steps of receiving, by a server communicatively coupled to a network, a request for a domain name by a requester and determining whether the domain name is registered.", "When the domain name is registered a search history for the domain name to determine a first search metric is analyzed, and a first user interface is displayed listing the domain name and the first search metric.", "The first user interface enables the requester to participate in at least one of an auction process and a brokerage process to purchase the domain name.", "When the domain name is not registered, a search history for the domain name to determine a second search metric, which is different from the first search metric, is analyzed.", "A second user interface is displayed listing the domain name and the second search metric enabling the requester to purchase the domain name.", "In another implementation, the present disclosure provides a system including at least one server communicatively coupled to a network configured to receive a request from a requester.", "A domain name is identified by the request.", "The at least one server identifies the domain name as registered or not registered.", "When the domain name is not registered, the system includes a search metric determined for the domain name and a first user interface configured to display the domain name and the search metric.", "The first user interface enables the requester to purchase the domain name.", "In another implementation, the present disclosure provides a system including at least one server communicatively coupled to a network configured to receive a request for a domain name by a requester.", "The domain name is identified by the at least one server as registered or not registered.", "When the domain name is registered, the system includes a search history for the domain name to determine a first search metric, and a first user interface configured to display the domain name and the first search metric.", "The first user interface enables the requester to participate in at least one of an auction process and a brokerage process to purchase the domain name.", "When the domain name is not registered, the system includes a search history for the domain name to determine a second search metric, the second search metric being different from the first search metric.", "A second user interface is configured to display the domain name and the second search metric, the second user interface enables the requester to purchase the domain name.", "To acquire a domain name a user will often perform a search for a candidate domain name at a registrar's domain name registration website.", "The user can enter either a desired domain name or a number of search terms, which may be provided as text or any other input into the domain name registration website, and perform a query.", "In response to the query, the user will be presented with one or more candidate domain names that are relevant to the query.", "FIG.", "1 is a flowchart illustrating a method by which a registrar and, specifically, a web site operated by the registrar, can receive a domain name query request from a user and then display a listing of results in response to the request.", "Depending upon the status of the domain names returned in response to the user's query (e.g., registered or unregistered) the user may be presented with several search metrics for the domain names in the result listing.", "For example, if a particular domain name is available, the metrics displayed may include the probability that the domain name will be purchased within a date range and/or within a specified geographic location.", "The user may then have an option to purchase the domain name.", "As a non-limiting example, the method illustrated in FIG.", "1 (and all methods described herein) may be performed by any central processing unit (CPU) in any computing system, such as a microprocessor running on a server, and executing instructions stored (perhaps as scripts and/or software) in computer-readable media accessible to the CPU, such as a hard disk drive on a server.", "Such a server may be communicatively coupled to a network (e.g., the Internet) and may receive a request for a domain name (e.g., in accordance with step 100 of FIG.", "1) using that network.", "The server may be implemented as a singular computing device operating a number of CPUs or as a distributed computing system wherein different portions of the method may be distributed across different computer servers that are each in communication with one another over a computer network.", "Prior to performing the method shown in FIG.", "1, the registrar's domain name registration website may perform actions to prepare data sets or data collections that are utilized to perform the method of FIG.", "1.For example, the server hosting the domain name registration website may maintain a set of domain search logs 106 describing prior search activity on the domain name registration website.", "As a non-limiting example, the set of domain search logs 106 may be provided by any open source software (e.g., Apache Hadoop) capable of processing large datasets to generate data to be stored in a historical database.", "The domain search logs 106 may record information describing domain name searches performed by all users requesting or searching for candidate domain names using the domain name registrar's website.", "The information stored in the domain search logs 106 may include, for example, for each search executed, the search terms, number of results, the user's identifying information, the user's location, such as country or region, which may be derived from the user's IP address using geolocation software, the time and date on which a search occurred, the user's language and language preference (e.g., derived from the language settings of the user's browser), the type of computing device and browser executing the search, the status of the user requesting the search as a customer or non-customer of the registrar, the user's time zone.", "With access to the domain search logs 106, the server hosting the domain name registration website can process the data in the domain search logs 106 to generate a plurality of search metrics based upon the search query provided by the user at step 100.The metrics can then be displayed to the user to enable the user to understand in more detail the market for the domain names in which the user is interested.", "The search metrics, for example the total number of searches for a specific domain name, may be calculated in real time.", "The probability that the domain name will be purchased within a date range and/or within a specified geographic location, however, may be pre-calculated using a continuously improving engine used to update statistics.", "The domain search logs 106 may then be grouped by user location and country once a match is found for a requested domain name within a certain time period.", "The metrics are described in the further detail below.", "Referring to FIG.", "1, in step 100, a request including a domain name query is received via a suitable user interface.", "The request may come from any individual or entity having access to the network that may wish to research potential domain names for registration and may comprise any electronic request received by the server including, but not limited to, a Hyper Text Transfer Protocol (HTTP) request, email message, and/or Short Message Service (SMS) message (i.e., text message).", "The request may comprise any combination of data seeking information relating to a domain name, such as the name of a domain name or keywords or other data that may relate to a potential domain name or that can be analyzed to identify one or more domain names relevant to the query.", "As non-limiting examples, the request may comprise an HTTP request transmitted to a domain name registrar's website.", "To illustrate, FIG.", "2 is a screenshot showing an example user interface 200 by which a requester can initiate a search for a domain name in accordance with step 100 of FIG.", "1.Referring to FIG.", "2, the requester can enter the name of the desired domain (e.g., MikesBikes.com”) or other search terms that may be related to a desired domain name into search box 202.Then, after the query has been entered into search box 202, the requester can activate button 204 to perform the query.", "Returning to FIG.", "1, once the request is received, the domain search logs 106 may be updated at step 104 with the data relevant to the query received in step 100.This may involve, for example, creating a new entry in the domain search logs 106 that contains information describing the search query received in step 100, such as the user's location, the time and date on which the search query was received, and the specific query terms searched.", "This data is stored in the domain search logs 106 for later use in calculating metrics.", "In other implementations, the search logs 106 are not updated until the method depicted in FIG.", "1 has completed execution.", "Having received the query in step 100, in step 102 the query is executed and a number of candidate domain names are generated in a result listing.", "If the query included a specific domain name, the result listing may include that specific domain name and, optionally, a number of alternative domain names.", "If, however, the query included a number of search terms (or other data), rather than a specific domain name, the result listing may contain a number of candidate domain names that are relevant to the query.", "In some implementations, the result list may include only a single candidate domain name.", "Having generated a result list, metrics can be calculated for each domain name in the result list.", "Accordingly, in step 108, for each domain name in the result list, the server determines which search metrics to display.", "The determination of which metrics to display may be based upon a number of factors including the user's preferences, attributes of the query itself, or any other data accessible to the server.", "The metrics to be generated and displayed may also be determined by a status of the domain name.", "For example, if the domain name is already registered, a first set of metrics may be calculated, whereas if the domain name is not already registered a different set of metrics may be calculated.", "Potential metrics include but are not limited to, for example, the total number of requests for the domain name (e.g., MikesBikes.com) by all other requesters 112, the total number of requests for the domain name by other requesters within a specified date range 114 (e.g., the past 100 days, the past 2 months) as shown in FIG.", "2, the total number of requests for the domain name by other requesters categorized by geographic location 116 (e.g., city, state, country, region) as shown in FIG.", "3, and a total number of requests for the domain name by other requesters categorized by geographic location with a specified date range 118, as shown in FIG.", "3.In these examples, the total number of requests for a domain name by other requesters may refer to the number of queries performed by other users or requesters that have specifically stated the domain name in question (e.g., query explicitly searching for “MikesBikes.com”), or the number of keyword queries that have generated result listings that have included the domain name in question (e.g., “Michael Bicycle Store”).", "After the metrics to be displayed have been determined, the server analyzes the data provided by the domain search logs 106 and calculates the relevant of search metrics at step 110.Search metrics 112 and 116 may be pre-calculated values, allowing the plurality of search metrics to be displayed to the user at step 110 more quickly.", "Since the domain search logs 106 records all locations and the specific query terms searched for by all users using the domain name registrar's website, the domain search logs 106 may also store a running total of these values as new domain name queries occur.", "Therefore, the server may only need to calculate search metrics 114 and 118, for example, in real-time at step 110 depending on the date range and geographic location selected by the user on the domain registration website, thereby improving performance of the server.", "In order to display the search metrics to the user, the server accesses the data recorded by the domain search logs 106.For example, to calculate the number of prior searches 112 at step 110, the server can access a table in the domain search logs 106 that contains a record for each time a query is made for a specific domain name or relevant keyword.", "The server may then generate a total value for the number of times the domain name has been queried and display it to the user.", "To calculate the number of searches for a specific domain name in a date range 114, for example, the server accesses the domain search logs 106 containing a record and a date stamp for each query that has been made for the specific domain name or relevant keyword.", "The server can then generate from the date stamp information a total value for the number of times the domain name or relevant keyword has been queried during a specific date range (e.g., specified by the user) and display the result to the user at step 110.Similarly, to calculate the number of searches for the specific domain name or relevant keyword by geographic location 116, the server can access the domain search logs 106.Then, based upon a geographical region that can be defined, for example, by the user, the server can identify the number of searches that has occurred in that region for the domain name or relevant keyword and display the result to the user at step 110.The geographical region can be defined in a number of different ways, for example, by the user clicking on a point on a map and providing a radius around that point to define a geographical region, the user can also specify political boundaries (e.g., of a city, county, or state) that can be used to defined the geographical region, and the like.", "Alternatively, the geographical region can be determined implicitly—for example, by being based upon the user's current location.", "Likewise, to calculate the number of searches by geographic location within a date range 118, the server accesses the domain search logs 106 to determine the geographic location in which the specific domain name or keyword has been searched for by all other users, as well the date and time the queries were made.", "The server can then generate from these values a total value for the number of times the domain name or relevant keyword has been queried during the date range and geographic location specified by the user.", "The result can then be displayed at step 110.In some implementations, the metrics associated with a particular domain name may also include the probability that the domain name will be purchased within a particular period of time.", "This probability may be calculated from the proprietary data and search metrics obtained from the domain search logs 106.More specifically, the following function may be used to calculate the probability that the domain name will be purchased within a particular time period in a specific geographic location: P(domain name purchase in X days)=(Number of purchases when the total count was similar)/(total count of people that searched for the domain name) For example, using the above function, if 80 users searched for the domain name ‘mysmallbiz.com’, and 60 people bought one of the suggested alternatives in a 7 day period, then the probability would be 60/80 or 75%.", "Similarly, if today, a user searched for the domain name ‘allmymagic.com’ and 62 results are shown (i.e., a range of 55 to 65 hits), the 75% probability may be used based on the result for ‘mysmaillbiz.com’.", "In some embodiments, other variables may be used, either singularly or in combination, when calculating the probability that the searched domain name will be purchased.", "These variables may include, but are not limited to the following: the number of total domain names sold relative to the number of domain names sold by GODADDY.COM in a specific region, the mention of the searched keyword in social media (e.g., Twitter, Facebook, etc.)", "in a specific timeframe, promotional offers offering discounted pricing on domain names, both by GODADDY.COM and competitors, introduction of new gTLDs in the domain market, renewals of similar sounding domain names, web pages actively hosted on the domains versus parked pages, and the existence of Facebook pages.", "In step 120, for each of the candidate domain names in the result listing, the registration availability of each domain name is determined, perhaps by at least one server ascertaining whether the domain name (e.g., “MikesBikes.com”) has already been registered by checking the SRS database associated with the TLD of the domain name (.com in the instant example).", "As an additional non-limiting example, any of the systems and/or methods may be used as described in U.S. Patent Application Publication No.", "2004-0199520 entitled: “Method for Checking the Availability of a Domain Name,” which is assigned to The Go Daddy Group, Inc. and incorporated herein by reference.", "Alternatively, any method of determining domain name registration availability known in the art or developed in the future may be used.", "In some implementations, the registration status of a particular domain name may be a factor in determining which metrics are to be displayed for the domain name in a result listing.", "As such, step 120 can be, in some implementations, performed before step 108 enabling the registration status of the domain name to be a factor in determining which metrics to display.", "If, in step 122 the domain name is determined to be available for registration, the domain name is displayed to the user in step 130 along with the metrics that were calculated for the domain name in step 110 as well as an option to purchase the domain name.", "For example, FIG.", "2 shows a domain name (“MikesBikes.co”) that is available for registration along with metrics showing how many times that domain name has been searched for in the last 30 days.", "FIG.", "3 shows a domain name (“MikesBikes.co”) that is available for registration along with metrics showing how many times the domain name has been searched for in the last 30 days along with a map depicting geographically-restricted metrics for the domain name.", "FIG.", "4 shows a domain name (“MikesBikes.co”) that is available for registration along with metrics showing how many times the domain name has been searched for in the last 30 days along with a map depicting geographically and time-restricted metrics for the domain name.", "In step 130 any additional metrics calculated in step 110 may also be displayed along with the domain name, such as the calculated probability of the domain name being purchased by another requester within a specified time frame, as shown in FIG.", "4.By displaying to the user the probability that the requested domain name within a geographical location or in general will be purchased by another requester may give the requester a sense of urgency and enable them to purchase the requested domain name before the domain name is purchased by another.", "The domain name then may be provided for registration and the user may add the domain name to their cart at step 132 by pressing the button 230, as shown in FIG.", "2.This step may be accomplished by any method of informing a potential registrant that a domain name may be available for registration.", "As a non-limiting example, where a request for a domain name is received (step 100) via an electronic request (e.g., HTTP request, email message, SMS message, text message), the domain name may be provided for registration via similar electronic communication means, perhaps via a server.", "Thus, an HTTP domain name request may be responded to with an HTTP response that provides a webpage listing the domain name for registration, perhaps as a hyperlink.", "If the potential registrant clicks on the domain name, the potential registrant may be taken to a domain name registration website to check out at step 136, as shown in FIG.", "1.Domain name registration may be accomplished by any domain name registration method known in the art or developed in the future, perhaps via a website-enabled domain name purchase and registration system, such as that described in detail above and/or may be available on GODADDY.COM's website.", "Alternatively, domain name registration may be accomplished via human to human communication, perhaps via a telephone call or in-person meeting.", "Domain names may be registered by, as non-limiting examples, any individual or entity including, but not limited to a domain name registry, domain name registrar, hosting provider, and/or software application developer or distributor.", "Returning to step 122, if the domain name is not available for registration (e.g., the domain name has already been registered by another), in steps 124, 126 and 128 additional options can be displayed for the user to either purchase the domain name at a premium, purchase the domain name via a domain name auction service, such as GODADDY.COM's GODADDY AUCTIONS service, or send a message to the domain name holder to make an offer to purchase the domain name via a brokerage process, respectively.", "These options can then be displayed for the user in conjunction with step 130 along with the metrics that are relevant to the domain name.", "Alternatively, if the domain name searched for by the current user was previously purchased by a GODADDY.COM customer and has a parked page, an interest icon (not shown) may be clicked by the current user to contact the owner of the domain name through GODADDY.COM.", "If the user decides to purchase the domain name via one of the mechanisms provided via steps 124, 126 and/or 128, the user may add the domain name to their cart at step 132 by pressing button 230, as shown in FIG.", "2.The user may then click on the domain name to be purchased and may be taken to the domain name

window 44 is constituted by a member having high ultraviolet light transmittance, such as quartz (SiO2), sapphire (Al2O3), and amorphous fluororesin.", "On the side wall 30, a first inlet port 32, a

connected to the outlet port 36 and extends in a radial direction perpendicular to a longitudinal direction of the casing 28, similarly to the inflow pipes.", "Each of the first light source 12 and the second light source 14 includes an light emitting diode (LED) that emits ultraviolet light of which the center wavelength or peak wavelength falls within a range of about 200 nm to 350 nm.", "The first light source 12 and the second light source 14 may suitably include an LED that emits ultraviolet light of which the wavelength falls within a range of about 260 nm to 270 nm, which has high sterilization efficiency.", "As such an ultraviolet LED, one using aluminum gallium nitride (AlGaH) is known, for example.", "The first light source 12 is disposed near the first end surface wall 38 to emit ultraviolet light toward the inside of the treatment chamber 50 through the first window 42.Also, the second light source 14 is disposed near the second end surface wall 40 to emit ultraviolet light toward the inside of the treatment chamber 50 through the second window 44.At least part of the ultraviolet light from the first light source 12 is reflected by the inner surface of the side wall 30 and travels in the longitudinal direction of the treatment chamber 50 toward the second end surface wall 40.Similarly, at least part of the ultraviolet light from the second light source 14 is

the sterilization device 10 irradiates and sterilizes a fluid flowing through the first inflow path 52 and the second inflow path 54 into the treatment chamber 50 with ultraviolet light emitted by the first light source 12 and the second light source 14, and the fluid after the treatment flows out through the outflow path 56.At the time, the fluid flowing in through the first inflow path 52 strikes

multiple inlet ports are provided, turbulent flows can be generated in multiple regions within the treatment chamber 50.Also, since multiple light sources are provided respectively according to multiple positions where turbulent flows are generated, the fluid in the turbulent states can be irradiated with strong ultraviolet light.", "Therefore, compared to the case in which a single inlet port is provided or in which a light source is provided near the outlet port where the fluid is in a laminar state, the irradiation efficiency of ultraviolet light for a fluid can be improved.", "According to the present embodiment, since a turbulent state is generated by devising the positions of the inlet ports connected to the treatment chamber 50 and the direction of the inflow paths, instead of generating a turbulent flow by providing a turbulence plate or a turbulence generating mechanism within the treatment chamber 50, the flow path structure 20 can be simplified.", "Therefore, the irradiation efficiency of ultraviolet light for a fluid can be improved, while an increase in necessary parts or the manufacturing cost caused by providing a turbulence generating mechanism can be prevented.", "According to the present embodiment, since ultraviolet light is emitted from the both end surfaces of the treatment chamber 50 of a tubular shape, in the longitudinal directions of the treatment chamber 50, ultraviolet light can be provided to the entire inside of the treatment chamber 50.Therefore, besides the end part regions of the treatment chamber 50, which get into a turbulent state, the middle region 62 of the treatment chamber 50 can also be irradiated with ultraviolet light, so that the irradiation efficiency of ultraviolet light for a fluid can be further improved.", "According to the present embodiment, since the cross-sectional area of flow of the treatment chamber 50 is made larger than that of each of the multiple inflow paths, the flow rate of a fluid in the treatment chamber 50 can be lowered, so that the residence time of the fluid in the treatment chamber 50 can be increased.", "With the different cross-sectional areas of flow, a turbulent state can be generated more easily near an inlet port.", "Such functions can further improve the irradiation efficiency of ultraviolet light for a fluid.", "The flow path structure 20 may desirably have a shape that is symmetric with respect to the outflow pipe 26.More specifically, the flow path structure 20 may desirably have a shape symmetric with respect to a plane that is perpendicular to a longitudinal direction of the treatment chamber 50 and that passes through the center position of the outflow pipe 26.In this case, the outlet port 36 is provided at a position where the distance from the first end surface wall 38 is equal to the distance front the second end surface wall 40, and the first inlet port 32 and the second inlet port 34 are provided at positions where the distances from the outlet port 36 are the same.", "Also, the first inflow pipe 22 and the second inflow pipe 24 are formed to have the same cross-sectional area of flow.", "By employing such a symmetric structure, the flow of a fluid flowing in through the first inflow pipe 22 and the second inflow pipe 24 can be uniformed, and the fluid after the treatment can be made to smoothly flow out through the outflow pipe 26.", "(First Modification) FIG.", "3 is a sectional view that schematically shows a configuration of the sterilization device 10 according to a modification.", "The present modification differs from

provided to be inclined so that the distance from the outflow pipe 26 decreases with increasing distance from the casing 28.Since the first inflow pipe 22 is provided to be inclined, a fluid flowing through the first inflow path 52 into the treatment chamber 50 is likely to pass near the first end surface wall 38 before flowing toward the outlet port 36.The intensity of the ultraviolet light from the first light source 12 is highest near the first end surface wall 38, so that, by allowing the fluid to pass closer to the first end surface wall 38, the irradiation efficiency of ultraviolet light for the fluid can be further improved.", "The angle θ between the radial direction of the treatment chamber 50 and the extending direction of the first inflow pipe 22 may be set arbitrarily, but it may desirably foe set within a range of about 5 to 60 degrees, and more suitably be set within a range of about 10 to 45 degrees, for example.", "By setting the angle θ to such a value, a turbulent flow is more likely to be generated in the first end part region 58, and the fluid can be made to pass near the first end surface wall 38 before flowing toward the outlet port 36.As with the first inflow pipe 22, the second inflow pipe 24 is attached to the second inlet port 34 so as to extend in a direction inclined to a radial direction of the treatment chamber 50.The second inflow pipe 24 is provided so that a fluid flowing through the second inflow path 34 toward the treatment chamber 50 has a velocity component from the second inlet port 34 toward the second end surface wall

22, since the second inflow pipe 24 is provided to be inclined, a fluid flowing through the second inflow path 54 into the treatment chamber 50 is likely to pass near the second end surface wall 40 before flowing toward the outlet port 36.The intensity of the ultraviolet light from the second light source 14 is highest near the second end surface wall 40, so that, by allowing the fluid to pass closer to the second end surface wall 40, the irradiation efficiency of ultraviolet light for the fluid can be further improved.", "The angle between the radial direction of the treatment chamber 50 and the extending direction of the second inflow pipe 24 may be set arbitrarily, but it may desirably be set within a range of about 5 to 60 degrees, and more suitably be set within a range of about 10 to 45 degrees, for example.", "By setting the angle to such a value, a turbulent flow is more likely to be generated in the second end part region 60, and the fluid can be made to pass near the

subject and treating a localized area of the subject with a device that emits heat, NIR light, and/or alternating magnetic current such that at least some of the micelles inside the subject near the

number of reasons.", "Polymeric micelles not only improve physicochemical properties of the loaded-drug but also control drug release over a period of time at a particular area (1).", "Several kinds of polymer have been investigated such as PLGA and PCL because of their biodegradability.", "However, the ability to control the drug release triggered by external stimuli needs to be improved.", "Triggered-responsive materials have recently attracted a great deal of attention from researchers (2, 3).", "These materials better control drug release at specific targets to maximize therapeutic outcomes and minimize adverse drug reactions from non-specific release.", "One of the most common methods to trigger drug release is to use temperature (4).", "Most traditional thermal sensitive polymers can undergo the structural change between hydrophilic and hydrophobic parts of their polymer.", "Some polymers have a lower critical solution temperature (LCST) such as Poly (N-isopropylacrylamide, PNIPAAM).", "They can undergo phase changes when heated above LCST leading to structural shrinkage and squeezing out of a small molecule drug.", "Whereas polymers that possess an upper critical solution temperature (UCST) can swell and become more hydrophilic when the temperature is above their UCST (2, 5, 6, 7, 8).", "However, the polymer backbone of these traditional thermal sensitive polymers fails to cleave resulting in the inability of releasing nanoparticles loaded inside the micelles.", "Those nanoparticles remain in big clusters, ≥100 nm in size and may obstruct deep tumor penetration (9, 10, 11).", "To overcome high interstitial pressure and dense collagen matrix in tumor, nanoparticles with the size smaller than 50 nm are necessary (12).", "One of the most well-known reversible chemical reactions is Diels-Alder reaction.", "Diels-Alder (DA) and retro Diels-Alder (rDA) reactions were discovered in year 1928 in Germany by Professor Otto Diels and his student, Kurt Alder.", "This spectacular discovery resulted in the receipt of the Nobel Prize in Chemistry in 1950 (13).", "In 1994, Kuramoto et al made a hydrophobic polymer by using this reaction.", "They used difurfuryl adipate (DFA) for the furan source and used bismaleimido-diphenyl-methane (BMD) for the maleimide source (14; herein incorporated by reference).", "After that, the DA reaction has been intensive studied by using different structures of furan and maleimide molecules (15).", "However, the Diels-Alder reaction has not been widely used and has limited application because it requires a relatively high temperature to induce the reversible reaction.", "McElhanon et al, 2004 synthesized an easily removed surfactant by using 2-N-dodecyl hydrophobic furan and N-(4-hydroxyphynyl) hydrophilic maleimide (16).", "This surfactant was proved useful as removable templates for the construction of microporous materials.", "Yamashita, 2011 made use of the maleimide-modified polyethylene glycol (Mw 20,000) to conjugate with furfuryl disulfide-gold nanorods.", "The high temperature induces rDA leading to the release of polyethylene glycol from the gold

between a compound with a furan end group and a compound with a maleimide end group.", "DETAILED DESCRIPTION The present invention provides compositions, systems, and methods employing cleavable polymeric micelles.", "For example, provided herein are compositions comprising micelles that contain a hydrophobic agent (e.g., metal nanoparticles and/or therapeutic agent), where the micelles are formed from a plurality of amphiphilic polymer molecules that comprise a hydrophilic polymer and a hydrophobic polymer, where the hydrophobic polymer comprises a cleavable Furan-Maleimide adduct.", "Also provided herein are methods of administering such compositions to a subject and treating a localized area of the subject with a device that emits heat, NIR light, and/or alternating magnetic current such that at least some of the micelles inside the subject near the localized area are disrupted (e.g., releasing a therapeutic agent).", "In certain embodiments, provided herein methods for Diels-Alder amphiphilic block copolymer synthesis and its applications for (1) coating nanoparticles and micelle formation, (2) controlled drug and nanoparticle release, and (3) controlled transformation process—single and ball-like structure of iron oxide micelles.", "With the use of cleavable amphiphilic block copolymer, one is able to transform the cluster nanoparticles encapsulated in the micelles to smaller size of single-dispersed nanoparticles and control drug release simultaneously.", "The single-dispersed nanoparticles, for example, allow for deep tumor or other tissue penetration.", "In certain embodiments, the micelles with the ball-like structure provides the benefit of, for example, a high drug loading because they have more void space inside the micelles compared to other kind of micelles.", "As described in Example 1 below, iron oxide nanoparticles (IONPs) are used as a photothermal mediator to convert near-infrared light (NIR) to heat (see, e.g., 21, 19).", "The heat subsequently breaks apart the polymer backbone via retro Diels-Alder reaction (rDA) (see, e.g., 22, 23) resulting in the release of both the nanoparticles and a small molecule drug.", "Doxorubicin (Dox) is also encapsulated into the thermo-cleavable micelles together with IONPs.", "Dox was chosen as a model drug because it has been used in clinic for cancer treatment.", "During the process of transformation, Dox can also be released out of the micelles.", "This demonstrates that the thermo-cleavable polymeric micelles can generate both single-dispersed nanoparticles and control drug release at the same time leading to deeper tumor penetration and better therapeutic outcomes.", "Moreover, general production of individual-dispersed IONPs is difficult to control, and requires multi-steps (24, 25).", "Nonetheless, with the cleavable amphiphilic block copolymers described herein, the transformation of the cluster IONPs can be simply used to make single-dispersed IONPs micelles stable in aqueous solution.", "This can be applied, for example, to the process of single-dispersed IONPs production in aqueous at industrial level because of the ease of scale up, and reproducibility.", "The present disclosure is not limited by the type of metal nanoparticles that are employed.", "In certain embodiments, iron oxide nanoparticles are employed.", "Iron oxide nanoparticles (IONPs) have long been used for magnetic resonance imaging (MRI), hyperthermia, and photothermal therapy (PTT) (18, 19) because of their unique properties and safety.", "IONPs have capability of reducing T2 relaxation providing contrast images for the tumor areas and they also generate high temperature under alternating magnetic field or NIR light treatment (20).", "With these properties, IONPs could be used as diagnostic and PTT agents for cancer treatment.", "In certain embodiments, the thermo-cleavable micelles described herein can be used to control both small molecule drug and nanoparticle release by using the external triggers such as high temperature and NIR laser light.", "This controlled drug release can mitigate premature release and enhance drug accumulation at the tumor site.", "Moreover, the unique property of the thermo-cleavable polymers (e.g., DA-b-PEO copolymer) allows one to control the morphology of the nanocomposites.", "In particular embodiments, the single-dispersed IONPs can be easily produced by treating the original cluster IONP micelles with high temperature.", "This method provides a benefit over the traditional method as the reaction happens in aqueous solution.", "The single-dispersed IONPs also have the advantage for PTT in terms of deep tumor penetration due to a smaller diameter.", "Furthermore, the excessive addition of the thermo-cleavable polymer in the system allows one to make the ball-like IONP micelles.", "This structure has a bigger void volume, so it can entrap a higher amount of drug and nanoparticles, which benefits cancer therapy and yield a better therapeutic outcome.", "EXAMPLES Example 1 Cleavable Amphiphilic Block Copolymer Synthesis and Characterization This Example describes

the second legs 124b of the pole pieces 123 to provide the passive axial centering force though interaction of the permanent magnet 141 and ferromagnetic material of the pole pieces 123.The permanent magnet 141 of the rotor 140 and the dividing wall 115 form a gap 108 between the permanent magnet 141 and the dividing wall 115 when the rotor 140 is centered within the dividing wall 115.The gap 108 may be from about 0.2 millimeters to about 2 millimeters.", "For example, the gap 108 can be approximately 1 millimeter.", "The north permanent magnetic pole N and the south permanent magnetic pole S of the permanent magnet 141 provide a permanent magnetic attractive force between the rotor 140 and the stator 120 that acts as a passive axial centering force that tends to maintain the rotor 140 generally centered within the stator 120 and tends to resist the rotor 140 from moving towards the first face 111 or towards the second face 113.When the gap 108 is smaller, the magnetic attractive force between the permanent magnet 141 and the stator 120 is greater, and the gap 108 is sized to allow the permanent magnet 141 to provide the passive magnetic axial centering force having a magnitude that is adequate to limit the rotor 140 from contacting the dividing wall 115 or the inner surface 118a of the cap 118.The rotor 140 also includes a shroud 145 that covers the ends of the impeller blades 143 facing the second face 113 that assists in directing blood flow into the volute 107.The shroud 145 and the inner surface 118a of the cap 118 form a gap 109 between the shroud 145 and the inner surface 118a when the rotor 140 is levitated by the stator 120.The gap 109 is from about 0.2 millimeters to about 2 millimeters.", "For example, the gap 109 is approximately 1 millimeter.", "As blood flows through the blood flow conduit 103, blood flows through a central aperture 141a formed through the permanent magnet 141.Blood also flows through the gap 108 between the rotor 140 and the dividing wall 115 and through the gap 109 between the shroud 145 and the inner surface 108a of the cap 118.The gaps 108 and 109 are large enough to allow adequate blood flow to limit clot formation that may occur if the blood is allowed to become stagnant.", "The gaps 108 and 109 are also large enough to limit pressure forces on the blood cells such that the blood is not damaged when flowing through the pump 100.As a result of the size of the gaps 108 and 109 limiting pressure forces on the blood cells, the gaps 108 and 109 are too large to provide a meaningful hydrodynamic suspension effect.", "That is to say, the blood does not act as a bearing within the gaps 108 and 109, and the rotor is only magnetically-levitated.", "In various embodiments, the gaps 108 and 109 are sized and dimensioned so the blood flowing through the gaps forms a film that provides a hydrodynamic suspension effect.", "In this manner, the rotor can be suspended by magnetic forces, hydrodynamic forces, or both.", "Because the rotor 140 is radially suspended by active control of the levitation coils 127 as discussed above, and because the rotor 140 is axially suspended by passive interaction of the permanent magnet 141 and the stator 120, no rotor levitation components are needed proximate the second face 113.The incorporation of all the components for rotor levitation in the stator 120 (i.e., the levitation coils 127 and the pole pieces 123) allows the cap 118 to be contoured to the shape of the impeller blades 143 and the volute 107.Additionally, incorporation of all the rotor levitation components in the stator 120 eliminates the need for electrical connectors extending from the compartment 117 to the cap 118, which allows the cap to be easily installed and/or removed and eliminates potential sources of pump failure.", "In use, the drive coils 125 of the stator 120 generates electromagnetic fields through the pole pieces 123 that selectively attract and repel the magnetic north pole N and the magnetic south pole S of the rotor 140 to cause the rotor 140 to rotate within stator 120.For example, the one or more Hall sensors may sense a current position of the rotor 140 and/or the permanent magnet 141, wherein the output voltage of the one or more Hall sensors may be used to selectively attract and repel the magnetic north pole N and the magnetic south pole S of the rotor 140 to cause the rotor 140 to rotate within stator 120.As the rotor 140 rotates, the impeller blades 143 force blood into the volute 107 such that blood is forced out of the outlet opening 105.Additionally, the rotor draws blood into pump 100 through the inlet opening 101.As blood is drawn into the blood pump by rotation of the impeller blades 143 of the rotor 140, the blood flows through the inlet opening 101 and flows through the control electronics 130 and the stator 120 toward the rotor 140.Blood flows through the aperture 141a of the permanent magnet 141 and between the impeller blades 143, the shroud 145, and the permanent magnet 141, and into the volute 107.Blood also flows around the rotor 140, through the gap 108 and through the gap 109 between the shroud 145

two different actual measure flow rates.", "For example, for the estimated flow rate curve 220-9000 for an impeller rotation rate of 9000 rpm, the same estimated flow rate of 8.0 L/min corresponds to two different actual measured flow rates of about 7.8 L/min and 10.6 L/min.", "Moreover, for all actual measured flow rates above 9.3 L/min for an impeller rotation rate of 9000 rpm, the actual power consumption drops with increasing flow rate thereby resulting in increasing magnitude of error between the estimate flow rate 220-9000 and the exact estimated flow 222.Such a doubled value characteristic can also be seen in the data displayed in FIG.", "8 for impeller rotation rates of 4000 rpm to 9000 rpm.", "Accordingly, estimating flow rate based only on impeller rotation rate and

significant change.", "Above 11.0 L/min, the corresponding drive current used to rotate the impeller drops down to about 1600 counts at about 13.0 L/min flow rate.", "Accordingly, estimated flow rate based only on drive current for impeller rotation rate of 9000 rpm may deviate increasingly from actual flow rate for flow rates above 10.0 L/min.", "FIG.", "17 is a plot showing an observed correlation between measured flow and the target reference center value of the example blood pump of FIG.", "14 operated at 9000 rpm.", "As illustrated in FIG.", "17, for measured flow rates from 1 L/min to 8.0 L/min, the corresponding target reference center value shows a substantially linear decrease.", "From 8.0 L/min to 9.0 L/min flow rate, the corresponding target reference center value shows no significant change.", "Above 9.0 L/min flow rate, the corresponding target reference center value exhibits a substantially linear increase with increasing flow rate.", "Therefore, the target reference center value can be used to increase the accuracy of estimated flow rate, at least in the 9.0 L/min and higher range for the example blood pump of FIG.", "14 operated at 9000 rpm.", "An interesting observation from FIG.", "15 and FIG.", "17 is that the target reference center value is correlated with flow rate.", "Although the target reference center value also has bell curve shape meaning it also has double value problem for use in estimating flow rate, its double value range is different from the double value range of the driving current.", "Accordingly, one method that can be used to overcome the estimation error arising from the double valued nature of the driving current and flow rate correlation is to combine the driving current with the target reference center to predict the flow rate, for example, switching from driving current to the target reference center when driving current is in the double value range.", "There are at least two approaches for selecting when to switch between estimating flow rate based on driving current and estimating flow rate based on target reference center.", "One method selects a single flow rate value to switch for each particular rotor rotational rate.", "For example, when driving current is higher than 1600 counts in FIG.", "16, driving current is in the double value range, so the flow can be estimated based on target reference center instead of drive current when the driving current is higher than 1600 counts.", "A second method for determining what flow rate to switch between estimating flow rate based on driving current and estimating flow rate based on target reference center is based on how the bearing current varies in response to a pulsatile variation in the rotation rate of the rotor.", "The merit of the second method is that no calibration variable is involved in the second method's algorithm based switching, which may therefore be more robust in implementation.", "During pulsatile mode operation of the blood pump, the rotor rotational rate is periodically varied to simulate natural blood pulse.", "On a periodic basis, the rotor rotational rate is temporarily reduced from the current nominal rotational rate, then temporarily increased from the reduced rate to a rate greater than the current nominal rotation rate, and then reduced back down to the current nominal rotational rate.", "During each of these pulsatile rotation rate variations, a transition is also observed in bearing current.", "When bearing current is decomposed into d-q coordinates, it is found that the pulsatile transition of the bearing current changes with flow rate.", "FIGS.", "18 through 20 show the bearing currents filtered by the low pass filter and decomposed into d-q coordinates for different flow rates for a rotor rotation rate of 7000 rpm.", "The left subfigure is for the d axis, and right for the q axis.", "The d axis bearing current transition goes up then down at 10 L/min, and goes down then up at 3 L/min.", "The change in direction of the bearing current transition indicates that 10 L/min flow rate and 3 L/min flow rate are on different sides of the target reference center bell curve.", "FIG.", "21 is a plot showing an observed correlation between measured flow and impeller drive current for the example blood pump of FIG.", "14 operated at 7000 rpm.", "FIG.", "22 is a plot showing an observed correlation between measured flow and target reference center of the impeller of the example blood pump of FIG.", "14 operated at 7000 rpm.", "As shown in FIG.", "22, the target reference center value bottoms at 6 L/min.", "Therefore the slope of the target reference center curve with flow is reversed at 6 L/min, which causes the difference in pulsatile transition of the related rotor levitation current.", "This pulsatile transition change in bearing current can be used to set an estimation parameter having either a value of 0.0 or 1.0 based on whether the shape of the pulsatile transition change in bearing current indicates that the current nominal flow rate is lower or higher than the flow rate at which the target reference center curve bottoms.", "The estimation parameter can then be used to switch between estimating flow rate based on drive current when the flow rate is below the flow rate at which the target reference center curve bottoms and estimating flow rate based on target reference center value when the flow rate is above the flow rate at which the target reference center bottoms.", "For example, FIGS.", "21 and 22 show that for an example pump operated at 7000 rpm, driving current is a good estimator until about 7 L/min.", "Based on the pulsatile transition change in bearing current signature, the estimation parameter can be set to 1.0 at 7 L/min and higher so that the target reference center value can be used to estimate flow rate for flow rates of 7 L/min or higher.", "Calibration can also be done to fit the target reference center signal with the flow rate.", "To avoid switching noise when operating close to the switching flow rate, a weighing method can be used to put less weight on the target reference center signal when the pulsatile transition change in the bearing current indicates a flow rate corresponding to approximately the bottom of the target reference signal, and gradually add more weight to reference center signal at higher flow rate.", "The accuracy of this weighing method is illustrated in FIG.", "23, which graphically illustrates deviations between the resulting measured flow rate and actual flow rate for the example blood pump of FIG.", "14.Other suitable approaches for increasing the accuracy of flow rate estimation using parameters related to rotor levitation are also possible.", "For example, any suitable existing curve fitting techniques can be used to estimate flow rate based on any suitable combination of rotor rotation rate, drive current, and target reference center.", "Also, two or more different curve fits can be used to cover the entire range of flow rates.", "For example, one curve fit can be used to estimate flow rate at the low range of flow rates where flow rate is primarily a function of driving current, a second curve fit can be used at the high range of flow rates based on target reference center, and a third curve fit can be used at the mid-range of flow rates based on both driving current and target flow rate.", "Other bearing current related parameters can also be used.", "For example, the bearing current can be controlled to keep the rotor centered in the blood flow channel and the variation in the bearing current, which will be greater if the rotor is kept centered, can be used as another parameter in addition to rotor driving current to estimate flow rate.", "Impeller Position Based Pump Pressure Differential Estimation One of skill in the art would appreciate that the parameters related to impeller position described herein (e.g., bearing current, off-center position for the impeller to minimize bearing current) can be used alone or in combination to estimate pressure differential across the impeller (i.e., difference in pressure on the output side of the impeller to pressure on the input side of the impeller) in addition to or instead of estimating flow.", "For example, in many embodiments of the centrifugal blood pump 14, the impeller eccentricity for minimum bearing current appears to be solely or mostly dependent upon the pressure differential across the impeller.", "As a result, the pressure differential across the impeller can be estimated using a suitable function of the parameters related to impeller position described herein.", "Also, any suitable additional operational parameter of the blood pump, such as pump rotational speed, impeller drive current, and/or estimated blood flow through the pump, can be used alone or in any suitable combination in addition to the parameters related to impeller position described herein to estimate the pressure differential across the impeller.", "Moreover, one of skill would appreciate that the pressure differential across the impeller can be derived from the flow rate of blood through the blood pump and vice versa.", "The resulting estimated pressure differential can be used in any suitable way, including as a parameter on which operation of the pump is based to produce desired pressure differential across the pump suitable for particular patient physiological conditions and/or to detect and react to adverse pump conditions.", "Other variations are within the spirit of the present invention.", "Thus, while the invention is susceptible to various modifications and alternative constructions, certain illustrated

platform, such as including computer displays presented in each of the lenses of the glasses to the eyes of the user.", "In embodiments, the lenses and displays may be configured to allow a person wearing the glasses to see the environment through the lenses while also seeing, simultaneously, digital imagery, which forms an overlaid image that is perceived by the person as a digitally augmented image of the environment, or augmented reality (“AR”).", "HWC involves more than just placing a computing system on a person's head.", "The system may need to be designed as a lightweight, compact and fully functional computer display, such as wherein the computer display includes a high resolution digital display that provides a high level of emersion comprised of the displayed digital content and the see-through view of the environmental surroundings.", "User interfaces and control systems suited to the HWC device may be required that are unlike those used for a more conventional computer such as a laptop.", "For the HWC and associated systems to be most effective, the glasses may be equipped with sensors to determine environmental conditions, geographic location, relative positioning to other points of interest, objects identified by imaging and movement by the user or other users in a connected group, and the like.", "The HWC may then change the mode of operation to match the conditions, location, positioning, movements, and the like, in a method generally referred to as a contextually aware HWC.", "The glasses also may need to be connected, wirelessly or otherwise, to other systems either locally or through a network.", "Controlling the glasses may be achieved through the use of an external device, automatically through contextually gathered information, through user gestures captured by the glasses sensors, and the like.", "Each technique may be further refined depending on the software application being used in the glasses.", "The glasses may further be used to control or coordinate with external devices that are associated with the glasses.", "Referring to FIG.", "1, an overview of the HWC system 100 is presented.", "As shown, the HWC system 100 comprises a HWC 102, which in this instance is configured as glasses to be worn on the head with sensors such that the HWC 102 is aware of the objects and conditions in the environment 114.In this instance, the HWC 102 also receives and interprets control inputs such as gestures and movements 116.The HWC 102 may communicate with external user interfaces 104.The external user interfaces 104 may provide a physical user interface to take control instructions from a user of the HWC 102 and the external user interfaces 104 and the HWC 102 may communicate bi-directionally to affect the user's command and provide feedback to the external device 108.The HWC 102 may also communicate bi-directionally with externally controlled or coordinated local devices 108.For example, an external user interface 104 may be used in connection with the HWC 102 to control an externally controlled or coordinated local device 108.The externally controlled or coordinated local device 108 may provide feedback to the HWC 102 and a customized GUI may be presented in the HWC 102 based on the type of device or specifically identified device 108.The HWC 102 may also interact with remote devices and information sources 112 through a network connection 110.Again, the external user interface 104 may be used in connection with the HWC 102 to control or otherwise interact with any of the remote devices 108 and information sources 112 in a similar way as when the external user interfaces 104 are used to control or otherwise interact with the externally controlled or coordinated local devices 108.Similarly, HWC 102 may interpret gestures 116 (e.g.", "captured from forward, downward, upward, rearward facing sensors such as camera(s), range finders, IR sensors, etc.)", "or environmental conditions sensed in the environment 114 to control either local or remote devices 108 or 112.We will now describe each of the main elements depicted on FIG.", "1 in more detail; however, these descriptions are intended to provide general guidance and should not be construed as limiting.", "Additional description of each element may also be further described herein.", "The HWC 102 is a computing platform intended to be worn on a person's head.", "The HWC 102 may take many different forms to fit many different functional requirements.", "In some situations, the HWC 102 will be designed in the form of conventional glasses.", "The glasses may or may not have active computer graphics displays.", "In situations where the HWC 102 has integrated computer displays the displays may be configured as see-through displays such that the digital imagery can be overlaid with respect to the user's view of the environment 114.There are a number of see-through optical designs that may be used, including ones that have a reflective display (e.g.", "LCoS, DLP), emissive displays (e.g.", "OLED, LED), hologram, TIR waveguides, and the like.", "In embodiments, lighting systems used in

sensors such as a camera, rangefinder, hyper-spectral camera, Geiger counter, microphone, spectral illumination detector, temperature sensor, chemical sensor, biologic sensor, moisture sensor, ultrasonic sensor, and the like.", "The HWC 102 may also have integrated control technologies.", "The integrated control technologies may be contextual based control, passive control, active control, user control, and the like.", "For example, the HWC 102 may have an integrated sensor (e.g.", "camera) that captures user hand or body gestures 116 such that the integrated processing system can interpret the gestures and generate control commands for the HWC 102.In another example, the HWC 102 may have sensors that detect movement (e.g.", "a nod, head shake, and the like) including accelerometers, gyros and other inertial measurements, where the integrated processor may interpret the movement and generate a control command in response.", "The HWC 102 may also automatically control itself based on measured or perceived environmental conditions.", "For example, if it is bright in the environment the HWC 102 may increase the brightness or contrast of the displayed image.",

interface, and the like.", "As described herein, the HWC 102 may be in communication with external user interfaces 104.The external user interfaces may come in many different forms.", "For example, a cell phone screen may be adapted to take user input for control of an aspect of the HWC 102.The external user interface may be a dedicated UI, such as a keyboard, touch surface, button(s), joy stick,

include sensors (e.g.", "IMU, accelerometers, compass, altimeter, and the like) to provide additional input for controlling the HWD 104.As described herein, the HWC 102 may control or coordinate with other local devices 108.The external devices 108 may be an audio device, visual device, vehicle, cell phone, computer, and the like.", "For instance, the local external device 108 may be another HWC 102, where information may then be exchanged between the separate HWCs 108.Similar to the way the HWC 102 may control or coordinate with local devices 106, the HWC 102 may control or coordinate with remote devices 112, such as the HWC 102 communicating with the remote devices 112 through a network 110.Again, the form of the remote device 112 may have many forms.", "Included in these forms is another HWC 102.For example, each HWC 102 may communicate its GPS position such that all the HWCs 102 know where all of HWC 102 are located.", "FIG.", "2 illustrates a HWC 102 with an optical system that includes an upper optical module 202 and a lower optical module 204.While the upper and lower optical modules 202 and 204 will generally be described as separate modules, it should be understood that this is illustrative only and the present invention includes other physical configurations, such as that when the two modules are combined into a single module or where the elements making up the two modules are configured into more than two modules.", "In embodiments, the upper module 202 includes a computer controlled display (e.g.", "LCoS, DLP, OLED, etc.)", "and image light delivery optics.", "In embodiments, the lower module includes eye delivery optics that are configured to receive the upper module's image light and deliver the image light to the eye of a wearer of the HWC.", "In FIG.", "2, it should be noted that while the upper and lower optical modules 202 and 204 are illustrated in one side of the HWC such that image light can be delivered to one eye of the wearer, that it is envisioned by the present invention that embodiments will contain two image light delivery systems, one for each eye.", "It should also be noted that while many embodiments refer to the optical modules as “upper” and “lower” it should be understood that this convention is being used to make it easier for the reader and that the modules are not necessarily located in an upper-lower relationship.", "For example, the image generation module may be located above the eye delivery optics, below the eye delivery optics, on a side of the eye delivery optics, or otherwise positioned to satisfy the needs of the situation and/or the HWC 102 mechanical and optical requirements.", "An aspect of the present invention relates to launch technologies related to unmanned aerial vehicles (UAVs).", "In embodiments, the launch system is adapted to use a grenade launcher (e.g.", "40 mm grenade launcher) for ease of field integration.", "In embodiments, the launch system is adapted to be relatively quiet to allow for covert operations.", "When a grenade launcher is normally used in the field, quietness is not a significant requirement because the grenade being launched is going to land at a relatively short distance from the launcher and there is going to be a rather large noise made by the exploding grenade.", "The inventors of the present invention have realized that the use of a grenade launcher can provide ease for field integration and the launch should be relatively quiet to allow for those instances where one wants to launch the UAV and remain unnoticed.", "The inventors have also discovered that the use of an explosive charge to send the UAV to its usable or near usable height can significantly save on UAV battery life and hence increase the fly time of the UAV.", "FIG.", "3 illustrates a UAV launch system according to the principles of the present invention.", "In this embodiment, the launcher 320 may be a grenade launcher, such as a standalone grenade launcher, grenade launcher rifle combination, etc.", "An explosive charge may then be used to launch the UAV 314 from the grenade launcher 320.In embodiments, the UAV 314 is held in a launch position inside of a separable case 318.The separable case 318 may be designed to encase the UAV 314 in a launch position and the separable case 318, with the UAV inside, can be fired out of the launcher 320.The separable case 318 may then separate from the UAV in mid-flight.", "Once released from the separable case 318, the UAV may deploy flight sustaining elements, such as counter rotating blades that can keep the UAV in-flight in a controlled system, as indicating as unfold UAV position 312.Once the UAV achieves its fully deployed position 304 it may fly autonomously or through the control of a remote operator.", "The fully deployed UAV 304 may take the form of a dual counter rotating blade helicopter and it may operate a self contained camera with a field of view 310 to image the surroundings, sensors to sense environmental conditions of the surroundings, etc.", "The output from the camera and other sensors may be communicated to other systems through communication channel(s) 308.The UAV 304 may be controlled by a person on the ground in near proximity to the UAV.", "For example, a person wearing a HWC 102 may control the UAV as an externally controlled device 108 through the use of gestures 116, external control devices 104, etc.", "(as described herein elsewhere) with the HWC 102 communicating with the UAV either directly or indirectly.", "As indicated in FIG.", "3, the UAV may communicate with devices on the ground, such as HWC(s) 102, server(s), etc.", "to get files, streams, etc.", "from the UAV's camera and other sensor systems to persons in need of such information.", "The ground devices may further be used to control the flight and sensor systems of the UAV.", "For example, a person on the ground wearing a HWC 102 may receive files and streams of information from the UAV 304 and the person may also control the functions of the UAV by using control technologies described herein elsewhere.", "FIG.", "4 illustrates a UAV launch system adapted to be loaded and fired from a grenade launcher (not shown).", "The UAV launch system illustrated in this embodiment includes a separable launch case 318, which houses the UAV copter 314 in a launch configuration.", "The separable launch case 318 is secured to a retained propellant case 418.Both the separable launch case 318 and the retained propellant case are configured to be loaded into a grenade launcher for launching.", "The retained propellant case 418 houses a piston 410 that travels on a post 404.The piston 410 is illustrated in the pre-launch or down position.", "The retained propellant case 418 also includes a propellant container that contains a propellant 408.The grenade launcher (not shown) will trigger the propellant 408 to initiate the UAV launch.", "The propellant container has vents that allow the propellant to expand rapidly into the nearby container once triggered.", "The expanding gas pushes the piston 410 towards the UAV 314 and the separable launch case 318.The piston travels along the post 404 and the piston is stopped by the stop 402 towards the top of the post 404.The piston 410 has a seal 412 that seals, at least temporarily, the vessel below the piston 410 to contain a substantial amount of the gas that expands into the vessel from the triggered propellant.", "The upper portion of the piston 410 may also be sealed to help prevent the expanding gas from escaping into the surrounding environment.", "The seal 412 contains the expanding gas and resulting pressure and also prevents a loud noise from being generated by containing the gas.", "If the gas were allowed to escape to the surrounding environment quickly a loud noise would occur and the launch event would be marked by a loud audio signature.", "The seal(s) 412, or others, causing the expanding gas to be contained may permit the gas to slowly escape following the launch; so long as the leak is slow it will not cause a loud noise.", "The purpose of the seals is to contain the gas pressure to prevent a loud launch noise, so a substantial portion of the gas needs to be contained for at least a short period of time and then the gas can slowly escape around the seals.", "FIG.", "5 illustrates a UAV communication network in accordance with the principles of the present invention.", "Once deployed, the UAV 304 may communicate with ground personnel via optional communications links 508.For example, the optional communications links 508 may include a communication protocol that involves the UAV 304 communicating to a server node 504 on the ground and then the server node may communicate the information with the HWC 102 nodes 502.In other embodiments, the UAV 304 may communicate with an HWC 102 node 502 directly.", "The HWC 502 nodes and the server node may be arranged in an ad-hoc self-healing network arrangement.", "In other embodiments, the network topology and protocols may be otherwise arranged (e.g.", "spoke and hub, IP, etc.).", "Although

ratio of 20% are epitaxially grown in this order on, for example, 600 μm-thick substrate 101 made of silicon, and for example, source electrode 107 having a laminated structure of Ti and Al and drain electrode 108 having a laminated structure of Ti and Al are formed so as to be in ohmic contact with undoped AlGaN layer 104.For example, gate electrode 106 made of Ni and gate wire 110 made of Au are formed so as to be in Schottky contact with undoped AlGaN layer 104.Gate wire 110 is electrically connected to gate electrode 106, and formed so as to make an angle of 90° with respect to gate

electrode 107 is disposed so as to be surrounded by gate electrode 106 and gate wire 110.Further, in undoped GaN layer 103 and undoped AlGaN layer 104 immediately below gate wire 110, high resistance region 112, the resistance of which is increased by, for example, Ar ion implantation, is formed, and a boundary between high resistance region 112 and element region 113 is positioned immediately below the gate wire.", "Here, a resistance of high resistance region 112 is a value equal to or greater than a measurement limit value in usual resistance measurement.", "That is, high resistance region 112 is semi-insulating or insulating.", "Parameters of compositions and layer thicknesses of the layers described above are shown in Table 1, and materials of the electrodes are shown in Table

0 V for the semiconductor device of the present invention.", "That is, when Vgs is 0 V, Ids of the semiconductor device of the present invention is greater by a factor of 10−3 than Ids of the semiconductor device of comparative example, and it has been thus found that the semiconductor device of the present invention is superior in pinch-off characteristics to the semiconductor device of comparative example.", "This may be because in the present invention, electrons flowing out of source electrode 107 necessarily pass under gate electrode 106 formed on element region 113.Off-leak currents at a drain voltage of 600 V were compared between the semiconductor device of the present invention and the semiconductor device of comparative example.", "Results thereof are shown in Table.", "3.The comparison was made for two cases: a case where a temperature of surrounding of the semiconductor device (ambient temperature) was 25° C. and a case where the ambient temperature was 150° C. TABLE 3 Invention Comparative Example 25° C. 1.7 μA 1.6 μA 150° C. 31 μA 120 μA It was found from the results in Table 3 that when the ambient temperature was 25° C., there was little difference

than 100 μm is not preferred because an area of a wiring portion is relatively large in integration of the transistor.", "The length of the gate electrode being more than 800 μm is not preferred because a gate resistance increases to adversely affect switching characteristics.", "When the length of gate electrode 106 is changed, a length of each of source electrode 107 and drain electrode 108

choose to fund 20% of the transaction from a demand deposit account (e.g., a debit account) and 80% of the transaction from a non-demand deposit account (e.g., by a charge to a credit account).", "In some embodiments, if an account of the one or more of consumer accounts 131 has an account balance that is less than the amount of the transaction (or the portion of the transaction that consumer 129 has chosen to allocate to the account), loan module 126 of mobile device 120 can determine that there is a deficiency and can present an option to fund the transaction (or a portion of the transaction) using a non-demand deposit account, such as a loan account, a credit account, or a points account.", "In other embodiments, loan module 126 can present the option for funding the transaction through a non-demand deposit account even if there is no deficiency in the one or more of consumer accounts 129.In some embodiments, the loan account can be a new account that is created upon consumer 129 choosing to fund the transaction (or portion thereof) with the loan account.", "In other embodiments, the loan account can be for a previously authorized loan.", "In some embodiments, the loan account can have a pre-existing loan balance, which can be increased based on the amount of loan used to the fund the transaction.", "In several embodiments, the loan can be a small loan, and can be labeled a “micro-loan”), but can be treated the same as credit line for a loan instead of an overdraw of an account.", "In several embodiments, consumer 129 can make the decision from which account or accounts to fund the transaction, and/or to authorize a loan or a credit transaction, while at or near the point-of-sale terminal 110 in the store of merchant 119.In the same or other embodiments, loan module 126 can allow consumer 129 to choose the one or more accounts from which to fund the transaction after consumer 129 has left the store.", "In many embodiments, financial institution 130 can fund the transaction temporarily from a shadow account that the bank uses to fund overdraft transaction, which can be reimbursed from the one or more accounts selected by consumer 129.For example, consumer 129 can authorize a transaction at point-of-sale terminal 110 in the store, and financial institution 130 can authorize transfer of funds to financial institution 150 to pay merchant 119, and after consumer 129 leaves the store of merchant 129, loan module 126 can push a message to consumer 129 asking for one or more of consumer accounts 131 that consumer 129 wants to use to fund the transaction.", "The options of consumer accounts 131 can include the option to open a new loan account, or to add to the balance of an existing loan account.", "In some embodiments, consumer 129 can setup a list (e.g., prioritized list) of consumer accounts 131 to use for transaction using mobile device 120, and/or can setup before-hand an amount and/or percentage to use from one or more of the accounts.", "For example, consumer 129 can choose to use a debit account for the first $50 and then use a credit account for the rest.", "As another example, consumer 129 can choose to use a debit account for 40% of the transaction, and use a new micro-loan for the rest.", "In some embodiments, a points account can be used to pay for all or at least a portion of the payment.", "For example, consumer 129 can have a points account at financial institution 130, which can have a balance of points earned by consumer 129 at financial institution 130.In many embodiments, these points can have an exchange value, such that the points can be redeemed to pay for all or at least a portion of the payment.", "In many embodiments, after mobile device 120 has communicated with point-of-sale terminal 110 using communication module 124 to receive the merchant identifier and other transaction information, and consumer 129 has authorized the transaction, mobile device 120 can communicate with financial institution 130 and/or transaction system 140, either directly or through mobile wallet provider 160, to request a payment be made to merchant account 151 of merchant 119 from one or more of consumer accounts 131.For example, when mobile device 120 communicates with financial institution 130 (either directly or through mobile wallet provider 160) to request a payment be made, account module 134 of financial institution 130 can determine account information about merchant account 151, such as the account identifier of merchant account 151, at least partially based on the merchant identifier received from mobile device 130.In some embodiments, financial institution 130 can communicate with transaction system 140 to get the account information about merchant account 151, which can be stored in merchant account database 141.In some embodiments, financial institution 130 can save the account information about merchant account 151 so financial institution does not need to query the account information from merchant account database 141 in transaction system 140 for future transaction involving the same merchant identifier.", "In other embodiments, financial institution 130 can query for the account information from merchant account database 141 in transaction system 140 for each new transaction, or at occasional and/or regular intervals.", "In other embodiments, when mobile device 120 communicates with transaction system 140 (either directly or through mobile wallet provider 160) to request a payment be made, transaction system 140 can provide the account information about merchant account 151 to first financial institution 130.In many embodiments, having the account information about merchant account 151, financial institution 130 can initiate a payment to financial institution 150 from one or more of consumer accounts 131 to merchant account 151.In several embodiments, before initiating payment, authorization module 133 can determine whether to authorize payment from one or more of consumer accounts 131.For example, financial institution 130 can determine whether the payment amount is within the available funds in one or more of consumer accounts 131, determine whether one or more of consumer accounts 131 is currently open and in good status (or closed), authenticate the identity of consumer 129 using mobile device 120, and/or perform other actions.", "For example, in some embodiments, authentication module 121 can authenticate the identity of consumer 129, and that information can be communicated from mobile device 120 to financial institution 130.In some embodiments, mobile device 120 can prompt consumer 129 to authenticate before and/or after mobile device 120 receives the merchant identifier and/or the transaction information from point-of-sale terminal 110.In some embodiments, authorization module 133 can request additional authentication from authentication module 121 (which can be directly through a network between financial institution 130 and mobile wallet 120, or can be through mobile wallet provider 160 and/or through transaction system 140) after receiving the request for payment from mobile device 120 and/or after receiving the information about merchant 119 and/or merchant account 151.In a number of embodiments, authorization module 133 of financial institution 130 can perform different and/or varying levels of authentication based on various factors.", "For example, authentication module 121 and/or authorization module 133 can determine whether mobile device 120 used to send the request for payment has been previously used by consumer 129 for transaction with financial institution 130, whether biometrics of the consumer match stored biometrics of consumer 129, whether the requested transaction and associated details (e.g., the identity of merchant 119, the location of merchant 119, the payment amount, the one or more items to be purchased (e.g., a list of SKUs), and/or other suitable factors) are consistent with spending patterns of consumer 129, whether consumer 129 has reported mobile device 120 lost or stolen, whether consumer 129 has reported that credit cards, debit cards, or other information about one or more of consumer accounts 131 have been lost or stolen, and/or other suitable factors.", "In various embodiments, financial institution 130 can adjust the level of authentication used to verify the identity of consumer 129 based on one or more of these factors, and/or based on the payment amount, the identity of merchant 119, the location of merchant 119, historical spending of consumer 129, and/or other relevant information.", "In some embodiments, if one or more of consumer accounts 131 chosen by consumer 129 for the transaction is short on funds or otherwise cannot be fully used, loan module 135 can communicate with loan module 126 to present other funding options to consumer 129, such as the option for a micro-loan to fund all or part of the transaction, as described above.", "In many embodiments, after receiving authorization from authorization module 133, financial institution 130 can initiate a payment to financial institution 150 to transfer funds from one or more of consumer accounts 131 to merchant account 151.In a number of embodiments, the payment can be effected by sending payment information regarding a payment to be made to merchant account 151 from one or more of consumer accounts 131.In a number of embodiments, the payment information transferred from financial institution 130 to financial institution 150 can effectuate an authenticated credit push, which can irrevocably satisfy payment to the merchant and/or ensure that the merchant has good funds when consumer 129 leaves the store of merchant 119.For example, the payment can be a settlement credit push of funds for the payment amount from one or more of consumer accounts 131 to merchant account 151, which can be settled immediately.", "In various embodiments, the payment information transferred from financial institution 130 to financial institution 150 can effectuate a push promise to pay, which can provide an irrevocable guarantee of payment from financial institution 130 to financial institution 150.In several embodiments, for example, the payment can be an ACH (Automated Clearing House) credit push, which can provide an irrevocable funding guarantee.", "In many embodiments, the payment and/or the guarantee of payment can be sent in real-time from financial institution 130 to financial institution 150, which can happen for each such transaction.", "In some embodiments, the settlement of the transaction can happen later, such as in a nightly batch fashion, and in some embodiments, can happen through a different network, such as an ACH network or a credit network.", "In other embodiments, the real-time payment and/or guarantee of payment can be processed through an ACH network or a credit network.", "In some embodiments, the consumer can provide instructions to financial institution 130 to label the transaction as a debit or a credit transaction in one or more of consumer accounts 131, and in some embodiments can provide such instructions with the request to pay, or before or after the request to pay.", "In some embodiments, a credit transaction can be treated as a micro-loan, as described above.", "In certain embodiments, a debit pull with guaranteed promise to pay can be used, such that financial institution 150 can receive a guaranteed promise to pay from financial institution 130 and pull the funds using a debit pull.", "In various embodiments, transaction system 140 can store information regarding each transaction in transaction database 142.In several embodiments, transaction system 140 can serve as a central auditor for transactions between the financial institutions (e.g., 130, 150) in data communication with transaction system 142.In some embodiments, transaction system 140 can receive some or all of the information from the merchant security transaction code.", "In various embodiments, one or more portions of the merchant security transaction code can be encrypted by security module 115.For example, the merchant security transaction code can include an encrypted portion that can be decrypted by security module 146 of transaction system 140, which can be used to ensure that the message has not been tampered.", "In other embodiments, the merchant security transaction code is not encrypted, but is digitally signed, as described above, and the digital signature can be verified, in some embodiments, by security module 146, which can advantageously ensure that the merchant identifier correctly identifies merchant 119, so that the funds are paid to merchant account 151 corresponding to merchant 119.In a number of embodiments, financial institution 150, upon receiving payment and/or guarantee of payment, can notify point-of-sale terminal 110 and/or merchant 119 in real-time that merchant 119 has satisfactorily received payment from consumer 129.For example, the notification can include various information, such as the transaction identifier, the amount received in payment (or guarantee), the merchant identifier, and/or other information.", "Receiving the notice of good funds can allow merchant 119 to proceed, such as, for example, to allow consumer to leave the store of merchant 119 with the items.", "In some embodiments, for example, point-of-sale terminal 110 can match the notification to the pending transaction in point-of-sale terminal 110 using the transaction identifier.", "In certain embodiments, merchant 119 can match the notification to the point-of-sale terminal using the merchant identifier.", "In some embodiments, consumer 129 can receive a notification on mobile device 120 that the transaction has cleared, such as shown in FIG.", "22 and described below.", "In several embodiments, system 100 can advantageously provide a number of technological improvements that can overcome technological problems in conventional systems.", "For example, in several embodiments, system 100 can beneficially allow consumer 129 to send payment directly and/or immediately to merchant 119 when consumer 129 is checking out at point-of-sale terminal 110.In many embodiments, the payment systems and methods provided by system 100 described herein can eliminate the acquirer model that is conventionally used in payment card transactions.", "In several embodiments, the payment systems and methods provided by system 100 described herein can advantageously streamline payments by eliminating the need for the financial institution (i.e., the acquirer) of merchant 119 to request payment from the financial institution (i.e., the issuer) of consumer 129.For example, in many embodiments, financial institution 150 does not need to request payment from financial institution 130.In many embodiments, the payment systems and methods provided by system 100 described herein can beneficially ensure merchants (e.g., merchant 119) are paid by consumers (e.g., consumer 129) while eliminating and/or reducing many of the transaction fees paid to various entities in the conventional model.", "In a number of embodiments, the payment systems and methods provided by system 100 described herein can advantageously eliminate the chargeback liability of merchants for fraudulent transactions.", "In the conventional acquirer-issuer model, the merchant (e.g., 119) is responsible for verifying the credit or debit card to ensure that the card is not being used fraudulently.", "In several embodiments, the payment systems and methods provided by system 100 described herein can beneficially place the liability on the financial institution (e.g., 130) of the consumer (e.g.", "129), which can be in a better position (e.g., with more and/or better

includes or more artificial satellites 102 providing satellite service to one or more geographical regions.", "Each satellite 102 includes one or more transponders that transmit satellite service signals 104 wirelessly to the target geographical region(s).", "Under certain conditions, the satellite signals 104 can be received by a satellite terminal 106.Namely, the satellite terminal 106 is positioned within a target geographical region, without interference that might otherwise degrade or prevent reception of the satellite signal 104.By way of non-limiting example, DirecTV® and Dish

core programming from satellite in geostationary orbits at locations between 100 W and 120 W western longitudes.", "One such means of interference is related to the sun 114.The satellite terminal 106 typically has a highly directional antenna that is aimed at a location of the satellite 102.Under certain astronomical conditions, the sun may fall within the same region covered by the satellite terminal 106 antenna.", "Namely, the satellite falls on a line connecting the satellite antenna and the sun.", "This can be referred to as sun fade, sun transit, sun outage or solar conjunction.", "Such conditions can occur multiple times per year, for a period of about several minutes or more during which reception of the satellite signal is impeded, degraded or otherwise unavailable.", "In some instances, e.g., depending upon antenna mis-pointing, link margin, actual element performance and so forth, the durations of any single outage can be greater than 10 minutes.", "Fortunately, sun fade can be predicted with a high degree of precision based on locations of the satellite 102 and the satellite terminal 106.Sun interference prediction calculators are readily available, such as a calculator available online from INTELSAT, at http://www.intelsat.com/tools-resources/satellite-data-tools/sun-interface-calculator/.", "It is generally understood that adverse weather conditions can also affect the quality of satellite signal reception.", "For example, heavy rains 112 can attenuate the satellite signal enough to result in noticeable degradation of image quality.", "In extreme cases, the reception can be effectively disrupted.", "Satellite signal reception quality also can be affected by water or snow/ice accumulating over the surface of the satellite terminal antenna.", "In more detail, the satellite terminal 106 includes a satellite dish antenna 105 and a low-noise amplifier/block down-converter (LNB) 107.The dish antenna 105 is typically mounted external to a

the same premises can have more than one satellite antennas, e.g., pointing to different satellites and/or operating in different frequency bands.", "In such situations, each of the inputs of the multi-switch 108 is dedicated to a respective one of the received satellite signals 104.In some embodiments, one of the inputs of the multi-switch can receive inputs from a terrestrial antenna, e.g., receiving a local terrestrial wireless broadcast of television programming For example, a “3 In-4 Out” multi-switch can receive inputs from two block-down-converted satellite signals 109 and one local

include a tuner that responds to an input from a user that tunes the STB 110 to one of a number of available satellite service channels.", "In some instances, the block down-conversion of the LNB 107 provides multiple satellite service channels to each STB 110, allowing for selection of a particular channel to occur within the STB 110.A decoder decodes encoded channel signals, e.g., converting digital MPEG-2, H.264 or MPEG-4 signals to another format, such as analog NTCS format, HDTV format, and the like.", "It is understood that the down-converted RF signal can support multiple channels simultaneously, e.g., being distributed by the RF distribution network for processing by multiple satellite receivers.", "In the illustrative embodiment, the system 100 also includes an intelligent multi-switch 116.The intelligent multi-switch 116 receives media content from one or more alternate sources 118 and selectively provides the alternative media content to one or more of the STBs 110.For example, the intelligent multi-switch 116 provides the alternative media content 118 to the STBs 110 during occurrences of interference that might otherwise degrade or prevent reception of the satellite signal 104.In some embodiments, the intelligent multi-switch 116 identifies alternate media content based on the particular media content being consumed or otherwise presented to the STBs 110.Indication of media content being presented to the STBs 110 can be determined from one or more of a channel indicator, an Electronic Programming Guide (EPG), a program recording schedule for STBs 110 that include Digital Video Recorders (DVR), and the like.", "In some embodiments, the intelligent multi-switch 116 is IP enabled and has discrete signal detection that applies the content from a corresponding internet feed 118 (fed to IP multi-switch) and switches back to the satellite/terrestrial feed 109 when certain impairments come and go.", "Typically this type detection can be a signal frequency detector.", "The accuracy associated with the prediction of rain fade at one frequency based on the rain fade measured at another frequency is on the order of +/−2 dB.", "Thus effective fade detection requires fade measurements at only one frequency.", "However there are several detection methods to accomplish the switch, such as indication of a signal to noise ratio, a bit error rate, an error correction performance metric, and so forth.", "FIG.", "2 depicts another embodiment of a terrestrial portion 200 of the direct broadcast satellite system 100 described in FIG.", "1.The

222c, 222d (generally 222).", "The RF input terminals 220 are in communication with the RF distribution network 208, receiving the down-converted RF signals from the LNB 207.The network interfaces 222 are in communication with the intelligent multi-switch 216, e.g., receiving alternative media content from one of the network-accessible alternate content sources 218.In some embodiments, the multi-switch 216 is in communication with one or more of the satellite terminal 206 and the RF distribution network 208.In operation, any operational STBs 210 that are actively receiving satellite media content from the satellite signal 204, would be tuned to a channel associated with particular media content provided on that channel It is generally understood that the satellite service media content can be provided in a broadcast mode, e.g., according to a program lineup or schedule.", "Under such conditions, the program lineup can be identified by an electronic program guide identifying channels, time slots and programed media content.", "Accordingly, knowledge of a tuned channel and a time is sufficient to allow for an identification of a media content item being presented on display equipment attached to the STB 210 and/or recorded at a DVR.", "Alternatively or in addition, the satellite signal includes metadata that includes identifying information.", "Different metadata can be provided for each programmed channel of the satellite service lineup, such that access to metadata of a tuned channel can identify a media content being presented on the display equipment attached to the STB 210 and/or recorded at a DVR.", "It is also understood that in some embodiments, satellite service media content can be provided on a pay-per view basis and/or as an on demand basis.", "The intelligent multi-switch 216 can identify what media content items are being delivered to any active STBs 210, and further identify alternative media content items.", "The alternative media content items can include, without limitation, other versions of the same media content items.", "For example, a direct broadcast satellite service provider may offer some or all of their channel lineups in an ancillary service for delivery over terrestrial networks.", "The ancillary service can include, so-called, small screen versions of the media content items, generally intended for consumption on mobile devices.", "Thus, a high-definition version, including ultra-high-definition or “4K” version of a media content item might be delivered by the satellite service according to the satellite signal 204; whereas, a standard definition, low-definition or otherwise small-screen version can be provided via a cable service and/or via an IP media stream.", "The intelligent multi-switch 216 can identify an impairment in delivery of media content by way of the satellite signal 204, and in response, direct the alternative media content 219 to the STBs 210 by way of the

time, end time, duration, and the like.", "The intelligent multi-switch 116 detects a particular channel to which one of the STBs 110 is tuned.", "The intelligent multi-switch 116 can include a clock, or otherwise obtain a local time, such that the media content item or program can be determined from the channel and the time with reference to the EPG.", "The intelligent multi-switch 216 can identify an impairment as a complete loss of the satellite signal 204, a reduction in RF power of the satellite signal, e.g., due to a signal attenuation as might be experienced during heavy precipitation conditions.", "Alternatively or in addition, the impairment can be identified by an increase in a Bit Error Rate (BER) and/or a measure of error correction performance, e.g., an increase of forward error correction.", "Interjection by the multi-switch 216 to provide the alternative content to the STB 210, can occur in a reactionary manner, when the signal loss and/or error performance reaches or exceeds an intolerable level.", "Such scenarios might result in a loss of picture and/or audio, a reduced resolution, a blank screen, and the like.", "Alternatively or in addition, interjection by the multi-switch 216 can occur in a predictive manner in which a trend in performance can be used to predict a future loss of signal, or increase in error performance.", "Such predictions can be determined from one or more of trends of measured performance, weather sensory data, weather forecasts, and or predictions, e.g., from solar calculators to predict sun fades.", "Weather data and/or weather forecasts can be obtained from a weather service provider, such as the National Weather Service, a local news outlet and/or weather application programs or apps', such as The Weather Channel®.", "The Weather Channel® is a registered trademark of The Weather Channel, Inc.", "In some embodiments, the weather information can be obtained from a local weather station or weather sensor, such as a rain gauge, a hydrometer, a barometer, or the like provided at the subscriber premises.", "In some instances, the STB 210 provides an indicator that the signal loss/error performance is intolerable.", "This might include an application that flashes a billboard or similar message to presentation equipment indicating loss of signal and/or technical difficulties.", "Alternatively or in addition, one or more of the LNB 207 and the STB 210 provides a performance indicator related to the satellite signal 204 and or individual channels tuned to by the STBs 210.The signal indications can include Signal-to-Noise Ratio (SNR), BER, error corrections, and the like.", "The multi-switch 216 can be programed or otherwise include logic to act upon such signal indications in order to determine when to switch between satellite service media content and any alternative media content.", "The programming and/or logic can implement one or more rules that determine aspects of any transitions, such as when and under what conditions to switch between the regular and alternate content.", "The rules can include further restrictions, such as allowed alternative content sources, blocked alternative content sources, user preferences, and the like.", "It is understood that in at least some instances, the same programming content may not be available from other network sources depending on one or more of the program, the time, available sources, etc.", "In such instances, the multi-switch 216 can be configured to provide a suitable replacement alternative content item.", "Such suitable replacement content can be determined according to one or more of a genre, actor(s), producer, studio, rating, and the like.", "For example, if the multi-switch 216 determines that an STB 210 is tuned to a particular episode of “Modern Family,” the multi-switch can search a schedule and/or directory 224 of alternate media content to identify a suitable replacement.", "The suitable replacement in the illustrative example might include another episode of “Modern Family.” The other episode can be selected based on further detail, such as another episode from the same season, or close to the same season.", "Another episode dealing with similar subject matter, such as a story that focuses on one of the same actors can be selected, as well as other shows that may include the same actors, other family shows, and the like.", "It is envisioned in at least some instances that suitable replacement content can include advertising content.", "The selection of any particular advertising content to be substituted during outages can be based on perceived user demographics based on the particular content tuned to by the STB 210 at the time of the outage.", "Alternatively or in addition, the selection of alternative content that includes advertising can be based on one or more of user preference, subscriber demographics, past viewing history, and the like.", "In some embodiments, the multi-switch 216 includes a buffer, such as a circular buffer, that accepts a portion of the alternative content item.", "The buffer can be used to synchronize a transition between the particular media content item being presented at the STB 210 and the alternate content.", "For example, the buffer depth can be selected to store enough streamed media content to account for a greatest anticipated difference in timing between a satellite service presentation of a program, and a terrestrial service, “small-screen” presentation of the same show.", "Such delays can range from a few seconds, to tens of seconds, or more.", "The multi-switch can include circuitry and/or programing steps to detect or otherwise determine a time delay or time offset between the original and alternate media content items.", "The time delay or offset can be used to adjust the circular buffer such that alternate media content at an output of the circular buffer is approximately synchronized with the original media content presented to the STB 210.Having established synchronization, the multi-switch 216 can switch or otherwise instruct the STB 210 to switch between the original content item and the alternate content item.", "Such a switch can occur within the same frame, e.g., within the same “I frame” of an MPEG media stream.", "FIG.", "3 depicts another embodiment of a terrestrial portion 300 of the direct broadcast satellite system 100 described in FIG.", "1.The terrestrial portion 300 includes a satellite terminal 306 having a satellite

directed to one or more of the STBs 310 during any outage periods in which the original satellite service content may be degraded or otherwise unavailable.", "In some embodiments, the modulator 328 or another device, such as a wireless modem (not shown) can provide the alternate content wirelessly to the STBs 310.For applications in which the RF switches/combiners 330 include controllable switches, the switches 330 can receive a control signal, e.g., from the multi-switch and/or another control device to actuate a switch to the alternate content during an interruption to the satellite service and a switch back to the original content when the satellite service has been restored.", "In the illustrative embodiment, the intelligent multi-switch 316 obtains alternate content for each of the set-top boxes 310.Accordingly, the intelligent multi-switch 316 provides up to four IP streams (multicast or unicast for video on demand), to the modulator 328.Although separate RF switches/combiners 330 are illustrated, it is understood that any switching to/from alternate media content could be accommodated by the RF distribution network 308.Namely, instead of a 1×4 RF switch, the RF distribution network 308 can include a 2×4 switch capable of switching either the satellite RF signal from the LNB 307 or the alternate media content RF signal from the modulator 328 to one or more of the STBs 310.Although the modulator 328 is illustrated as having four independent RF outputs, it is understood that the modulator can modulate multiple IP packet streams onto a single RF signal, e.g., with the alternate content occupying corresponding frequency spectra to the satellite RF signal content being replaced.", "In this manner, the STB 310 is able to process the original satellite media content or the alternate media content without having to retune.", "Alternatively, in some embodiments, in which the down-converted RF satellite signal from the LNB 307 includes encryption or scrambling, it is understood that the modulator 328 can include an encryption and/or scrambling circuitry or program steps to encrypt and/or scramble the alternate content in the same manner as applied to the original down-converted RF satellite signal.", "Accordingly, the STB 310 can continue to process the alternate content in a like manner, including channel tuning, decryption and/or descrambling.", "In other embodiments, it is understood that the alternate content can be provided without encryption and/or scrambling, even though the original signal is encrypted and/or scrambled.", "In such instances, the STB 310 can be programmed to detect a change in encryption and/or scrambling of the signal and process the signal accordingly.", "A control signal indicating whether encryption and/or scrambling should be applied can be generated with the STB 310, e.g., upon a detection that the signal is/is not encrypted/scrambled.", "Alternatively or in addition, such a

the basket 24.FIG.", "4A provides an enlarged view of the right side of the rub ring 22 (with respect to the orientation of FIG.", "4).", "The tub ring 22 includes a circumferential side wall 90 that may extend in a generally vertical direction between a lower end 92 and an upper end 94.An L-shaped lip 96 may extend radially outward and downward from the side wall 90 at a location near the lower end 92 so as to form, with the side wall 90, a downwardly facing slot sized to receive the tub upper edge 20.The lip 96 may extend circumferentially around the entire tub ring 22 for receipt of the entire upper edge 20 of the tub 14, if desired.", "A plurality of circumferentially spaced tabs 98 (also seen in FIG.", "3) depending from the lip 96 may be configured to receive corresponding circumferentially spaced detents 100 or other mating structures on the tub 14 to mount and secure the tub ring 22 to the tub 14.A top wall 102 of the tub ring 22 extends radially inward from an outer edge 104, where the top wall 102 joins the side wall 90, to an inner edge 106 a distance sufficient to overlie at least a portion of the balance ring top wall 40.In the illustrated embodiment, the top wall 102 includes an inclined portion 108 that begins at the outer edge 104 and transitions to a generally horizontal or flat portion 110 that terminates at the inner edge 106.The outer edge 104 may be spaced a distance below the upper end 94 of the side wall 90 so as to form an open-top V-shaped channel 112, defined between the side wall 90 and the top wall inclined portion 108, around the tub ring 22 adjacent the top wall flat portion 110 (also shown in FIG.", "3).", "The channel 112 advantageously may catch liquid that splashes onto the top wall flat portion 110, and the liquid may drain downward into the tub 14.To facilitate draining, the inclined portion 108 of the top wall 102 may include drainage openings 114 at or near the bottom of the channel 112.The drainage openings 114 may be configured to direct the drained liquid into the space between the tub 14 and the basket 24.In contrast, liquid splashed onto a tub ring without such a channel may spill over the tub ring and down the side of the tub 14 onto the floor upon which the washing machine 10 rests.", "As seen in FIG.", "4B, which is an enlarged view of the left of the rub ring 22 (with respect to the orientation of FIG.", "4), a plurality of radial ribs 120 may be circumferentially spaced around the tub ring 22.The ribs 120 generally extend between the side wall 90 and the top wall 102 of the tub ring 22 to stiffen the tub ring 22 and thereby reduce the likelihood of the tub ring buckling.", "In particular, each rib 120 extends radially inward from side wall 90 through the channel 112, passes through the inclined portion 108 (shown in phantom) of the top wall 102, extends along the flat portion 110 of the top wall 102, and terminates at or near the top wall inner edge 106.A top edge 122 of the rib 120 joins with the top wall flat portion 110, except for a portion that is exposed in the area between the side wall 90 and the top wall flat portion 110 (i.e., the region of the inclined portion 108).", "A bottom edge 124 of the rib 120, or at least a portion thereof, may be inclined in a manner similar to the top wall 40 of the balance ring 36 so as to be complementary to the balance ring top wall 40.In the illustrated embodiment, the entire bottom edge 124 is inclined upward along a direction moving radially inward from the side wall 90, and the ribs 120 each have a generally triangular configuration, specifically a right-triangular configuration with the bottom edge 124 forming the hypotenuse of the triangle.", "Referring now to FIG.", "5, which is similar to FIG.", "4 but with the tub ring 22 shown exploded from the tub 14, the ribs 120 may be disposed around the entire tub ring 22, half of which can be seen in FIG.", "5.Any suitable number of ribs 120 may be spaced around the tub ring 22 to provide a desired stiffness, and the illustrated tub ring 22, as an example, includes about 32 of the ribs 120 with a spacing of about 65 mm (2.5 in.)", "between adjacent ribs.", "As an example, the bottom edge 124 of the rib 120 is inclined at about 35 degrees to complement the balance ring top wall 40.While the rib bottom edge 124 and the balance ring top wall 40 may have identical angles of inclination, it is not necessary for the inclination angles to match exactly to be complementary.", "The flat disc configuration of the top wall 102 provides resistance to ovalization of the tub ring 22 during high speed rotation of the basket 24, such as during spinning, and the ribs 120 extending between the side wall 90 and the top wall 102 increase stiffness to resist buckling.", "Such a design increases the natural frequency of the suspended mass, which, in turn, permits an increase in maximum spin speed.", "For example, a natural frequency increase of about 2 Hz, which is a reasonable increase for the tub ring 22, would allow the maximum spin speed to be increased as much as about 120 rpm for a basket having a diameter of about 63 cm (24.8 in.).", "The actual amount of maximum spin speed increase can be a function of several factors, including the size of the basket 24.These performance benefits are realized without sacrificing capacity of the basket 24 as a result of the complementary inclined portions of the tub ring rib bottom edge 124 and the balance ring top wall 40.In comparison, if the balance ring top wall 40 were flat or horizontal by raising the outer edge of the of the balance ring top wall 40, the tub ring top wall 102 would need to be shifted upwards (i.e., increase the vertical height of the side wall 90) to provide sufficient spacing between the balance ring top wall 40 and the ribs 120.Increasing the vertical height of the side wall 90 consumes valuable vertical space within the cabinet 12, which is typically limited to industry standard sizing, which depends on several factors, because it can necessitate a reduction in the vertical height of the basket 24 and, thus, cause a decrease in load capacity.", "However, the ribs 120 of the tub ring 22 illustrated above provide needed structural rigidity while fitting nicely into the space formed between the inclined balance ring top wall 40 and the tub ring top wall 102 without having to increase the vertical height of the side wall 90.FIG.", "6 presents a perspective view of an alternative embodiment of the tub ring 22′, where elements similar to those in the previous embodiment are identified with the same reference numeral bearing a prime symbol (′).", "The tub ring 22′ is substantially identical to the tub ring 22 in FIGS.", "3-5, except that the top wall 102′ includes only the flat portion 110′, which joins to the side wall 90′ in a generally perpendicular configuration, by example, at the upper end 94′ of the side wall 90′.", "Consequently, the top edges 122′ of the ribs 120′ are completely covered by the top wall 102′ as they extend radially inward from the side wall 90′.", "FIG.", "7 presents a perspective view of another alternative embodiment of the tub ring 22″, where elements similar to those in the previous embodiments are identified with the same reference numeral bearing a double prime symbol (“).", "The tub ring 22” is substantially identical to the tub ring 22′ in FIG.", "6, except that the top wall 102″ is formed by flat sections 130 and inclined sections 132 that alternate circumferentially around the tub ring 22″.", "The flat sections 130 have the same general configuration as the top wall 102′ in FIG.", "6 and extend circumferentially between adjacent ribs 120″, connecting the top edges 122″ of the adjacent ribs 120″.", "The inclined sections 132 extend radially inward from the side wall 90″, just like the flat sections 130, but the outer edge 104″ joins with the side wall 90″ at a location shifted downward from the upper end 94″ a distance about equal to the height of the rib 120″ at its connection to the side wall 90″.", "The inclined sections 132 may be inclined upward, moving radially inward, at an angle substantially equal to the inclination angle of the rib bottom edge 124″, connecting the bottom edges 124″ of adjacent ribs 120″.", "Because the flat and inclined sections 130, 132 alternate circumferentially, each rib 120″ joins to one of the flat sections 130 at the top edge 122″ and to one of the inclined sections 132′ at the lower edge 124″.", "Consequently, as one moves circumferentially around the tub ring 22″, the top wall 102″ transitions between the flat sections 130 and the inclined sections 132 at the ribs 120″, and the ribs 120″ can be considered as steps for the top wall 102″.", "For example, starting at a flat section 130, a first rib 120″ is a step down as the top wall 102″ transitions from the flat section 130 to an inclined section 132, then a second rib 120″ is a step up as the inclined section 132 transitions to the next flat section 130, then a third rib 120″ is a step down as that flat section 130 transitions to the next inclined section 132, and so on.", "The configuration of the top wall 102″ in the embodiment of FIG.", "7 facilitates formation of one or more treating chemistry cavities in the tub ring 22″.", "For example, the area bounded by two adjacent ribs 120″, the side wall 90″ between the adjacent ribs 120″, and one of the inclined sections 132 joining the adjacent ribs 120″ may define a treating chemistry cavity 134, identified in phantom in FIG.", "7 and shown more clearly in the sectional view of FIG.", "8.The treating chemistry cavity 134 may be sized to receive a desired type and/or dosage of treating chemistry and may be employed in addition to or in lieu of the dispenser 64.The treating chemistry may have any form, including, but not limited to a solid block, a powder, a gel, a liquid, an encased solid, powder, liquid, etc.", "(i.e., a pod), and so on.", "The treating chemistry may be any type of treating chemistry, non-limiting examples of which include one or more of the following: water, detergents, bleach, enzymes, fragrances, stiffness/sizing agents, wrinkle releasers/reducers, softeners, antistatic or electrostatic agents, stain repellants, water repellants, energy reduction/extraction aids, antibacterial agents, medicinal agents, vitamins, moisturizers, shrinkage inhibitors, and color fidelity agents, and combinations thereof.", "The inclined section 132 of the top wall 102″ may include one or more apertures 136 for dispensing of the treating chemistry into the tub 14 and/or the basket 24.The size, number, pattern, and orientation of the apertures 136 may vary depending on the type and/or form of the treating chemistry and the particular location for dispensing the treating chemistry.", "Optionally, the apertures 136 may fluidly communicate with a conduit or similar structure for directing the treating chemistry to a particular area of the tub 14 and/or the basket 24.As another option, the treating chemistry cavity 134 may be open at the top, as in the illustrations, or may be selectively closed by a movable lid.", "The tub ring may be modified in any suitable manner, including combining features of the different embodiments disclosed above as desired.", "For example, the tub ring may be mounted to the tub with structure other than the tabs and detents.", "Additionally, the bottom edges of the tub ring ribs may have only portions inclined, rather than the entire bottom edge being inclined, as shown in the Figures.", "As an example, the balance ring in the aforementioned and incorporated '373 publication has a top wall with only a portion thereof inclined, and the tub ring can have a bottom edge with only a portion inclined to be complementary to inclined portion of the balance ring top wall.", "For the embodiment with the alternating flat and inclined top wall sections, the seconds can be arranged in any desired pattern and need not be in an alternating pattern.", "While the invention has been specifically

secure processing of transactions, and relates more particularly to providing security and real-time transfers for transaction networks.", "BACKGROUND In a typical payment card transaction, a consumer provides an account number to a merchant to process a payment from the consumer for a transaction, and the merchant processes the payment transaction through the merchant's bank and/or payment processor (“acquirer”), which requests payment from the consumer's financial institution (“issuer”) through a payment processing network (e.g., a credit card network).", "The request initiated by the merchant for payment from the consumer is a pull-based payment model.", "The pull-based payment model generally involves significant transaction fees paid to various entities, such as the acquirer, the issuer, and the payment processing network.", "Moreover, the merchant is generally liable for chargebacks when the consumer's card is used fraudulently.", "Further, the consumer account information can be subject to theft under this model, as the consumer is providing the consumer's account information to third parties (i.e., parties other than the consumer's financial institution).", "A request initiated by the consumer, instead of the merchant, to send payment from the consumer's account to the merchant's account is a push-based payment model.", "The push-based payment model is often used for recurrent bill-pay transactions, but is generally not used for in-store transactions with merchants.", "BRIEF DESCRIPTION OF THE DRAWINGS To facilitate further

point-of-sale terminal 110 can communicate with security module 146 of transaction system 140, such as through application programming interface (API) calls.", "In other embodiments, security module 115 of point-of-sale terminal 110 can be self-contained computing instructions (i.e., that do not call security module 146 of transaction system 140) that are provided by transaction system 140 (e.g., at the time of enrollment and/or registration), or are based on instructions and/or a software development kit (SDK) provided by transaction system 140 (e.g., at the time of enrollment and/or registration).", "In many embodiments, security module 115 can be used by merchant 119 during a transaction to generate a merchant security transaction code.", "In many embodiments, the merchant security transaction code can include various information, such as the payment amount for the transaction, a transaction identifier that uniquely identifies the transaction to merchant 119 and/or point-of-sale terminal 110, the merchant identifier, a date and/or time of the transaction, a list of the items purchased, a digital signature, and/or other suitable information.", "In many embodiments, this information can be encoded in the merchant security transaction code using a suitable data encoding method.", "In many embodiments, the digital signature can be generated based on the data in the merchant security transaction code.", "The digital signature can be generated using a suitable digital signature code signing algorithm as part of a digital signature scheme.", "For example, the code signing algorithm can be public-key cryptography signing algorithm, such as those used in public key infrastructure (PKI), a cryptographic hash function, such as one of the Secure Hash Algorithm (SHA) published by the National Institutes of Standards and Technology (NIST) (e.g., SHA-256), or another suitable signing algorithm.", "The digital signature can be used to verify that merchant 119 created the merchant security transaction code and/or that the data in the merchant security transaction code has not been corrupted or tampered with after having being created by security module 115.In several embodiments, the merchant security transaction code can be a data code that can be transmitted between point-of-sale terminal 110 and mobile device 120 using a wireless data communication channel, as described above.", "In other embodiments, the merchant security transaction code can be encoded as a barcode, such as a one-dimensional (1D), two-dimensional (2D), or three-dimensional (3D) barcode, which can be optically ready by mobile device 120, such as by using a camera on mobile device 120, as described above.", "For example, the merchant security transaction code can be encoded as a matrix barcode, such as a QR code, and displayed on point-of-sale terminal 110 to be scanned by a camera on mobile device 120.In still other embodiments, the merchant security transaction code can be transferred manually from point-of-sale terminal 110 to mobile device 120 by the merchant security transaction code being displayed on point-of-sale terminal 110 and then being manually entered in mobile application 123 of mobile device 120.In many embodiments, system 100 can provide a transaction network for secure real-time payments.", "In several embodiments, mobile application 123 of mobile device 120 can be used by consumer 129 to push a payment from one or more of consumer accounts 131 to merchant account 151 to satisfy an expectation of payment while consumer 129 is waiting at point-of-sale terminal 110.In a number of embodiments, mobile application 123 can be associated with and/or configured to be associated with financial institution 130 and/or one or more of consumer accounts 131.For example, account module 122 can associate mobile application 123 with one or more of consumer accounts 131 at financial institution 130.In some embodiments, mobile application 123 can be provided by financial institution 130 as a mobile application for use on mobile device 120.In other embodiments, mobile application 123 can be associated with multiple different financial institutions and accounts of consumer 129 at those financial institutions.", "In some embodiments, mobile device 120 can be in data communication with financial institution 130 directly through a network, such as the Internet, or indirectly through one or more other systems, such as mobile wallet provider 160.In some embodiments, mobile device 120 can communicate with transaction system 140 directly through a network or through mobile wallet provider 160.In other embodiments, mobile device 120 cannot communicate with transaction system 140.In several embodiments, mobile application 123 can provide information to consumer 129 regarding the status of one or more of consumer accounts 131 and availability of funds in one or more of consumer accounts 131.For example, account module 122 of mobile device 120 can obtain information from account module 134 of financial institution 130 regarding one or more of consumer accounts 131 and provide that information to consumer 129.For example, if one of consumer accounts 131 has an available balance and/or available credit of $500, mobile application 123 can communicate the amount of the available funds for one or more of consumer accounts 131 to consumer 129, which can allow consumer 129 to know the amount of the available funds for spending before shopping for items and/or before attempting to purchase items.", "In a number of embodiments, account module 134 can provide account module 122 with various other information, such as the current status of one or more of consumer accounts 131, such as whether one or more of consumer accounts 131 is open and in good status (or closed), whether one or more of consumer accounts 131 has had recent not sufficient funds (NSF) activity, whether one or more of consumer accounts 131 has a stop payment order, and/or a buying power index of consumer 129 at least partially based on information about one or more of consumer accounts 131.In some embodiments, mobile application 123 can be used on mobile device 120 at point-of-sale terminal 110 to conduct a transaction.", "In several embodiments, mobile device 120 can receive the merchant identifier and other transaction information from point-of-sale terminal 110 of merchant 119.The merchant identifier can be associated with merchant account 151 of merchant 119.By receiving the merchant identifier, mobile application 123 can initiate a push payment from one or more of consumer accounts 131 at financial institution 130 to merchant account 151 at financial institution 150 to complete the transaction in real-time before the consumer leaves the store of merchant 119.In many embodiments, mobile device 120 can receive the merchant identifier and other transaction information from point-of-sale terminal 110 as part of the merchant security transaction code.", "In various embodiments, authentication module 121 can verify the identity of consumer 129.For example, authentication module 121 can verify the identity of consumer 129 using a personal identification number (PIN), a password, one or more fingerprints, voice recognition, other biometrics (e.g., mobile phone bio-measurements), and/or other suitable authentication methods, to ensure that consumer 129 is authorized to associate mobile application 123 with one or more of consumer accounts 131 and/or make payments using mobile application 123.In a number of embodiments, when mobile application 123 is used to conduct a transaction, mobile device 120 can be put in the proximity of point-of-sale terminal 110 to allow communication module 124 to receive information from point-of-sale terminal 110, such as the payment amount, the merchant identifier, a transaction identifier, and/or other information, such as the merchant name, the date and time, a list of SKUs (stock keeping units) of the one or more items to be purchased, etc.", "In many embodiments, mobile device 120 can receive the merchant identifier and other transaction information from point-of-sale terminal 110 as part of the merchant security transaction code.", "In several embodiments, security module 125 of mobile device 120 can verify the digital signature in the merchant security transaction code.", "For example, security module 125 can verify the digital signature using a signature verifying algorithm that is part of the same digital signature scheme that was used to digitally sign the merchant security transaction code.", "For example, a public key for merchant 119 can be used to verify the digital signature and the merchant security transaction code.", "By verifying the digital signature of the merchant security transaction code, security module 125 can verify that the merchant identifier is from point-of-sale terminal 110 of merchant 119 and is accurate, which can advantageously ensure that the funding from consumer accounts 131 will be sent to an account actually associated with the merchant instead of a fraudster.", "In some embodiments, mobile application 123 can be configured to allow one-click checkout, which can be enabled by selecting a button on mobile application 123 or by placing mobile device 120 in the proximity of a data transmitter on point-of-sale terminal 110.In some embodiments, mobile application 123 can be configured to scan items and conduct transactions in real-time as items are taken from the shelf and scanned by mobile device 120 or placed within a “smart” shopping cart, such that checkout can take place in an aisle of the store, rather than at point-of-sale terminal 110.In other embodiments, checkout can take place automatically when consumer 129 exits the store of merchant 119.In a number of embodiments, mobile application 123 can receive the merchant identifier upon entering the store of merchant 119 or from a shopping cart having data transmitted in the store of merchant 119.In some embodiments, the mobile application 123 can send information from mobile device 120 to point-of-sale terminal 110, such as information regarding consumer 129, such as personally identifiable information, loyalty rewards number(s), shopping patterns, points, buying power index, and/or other suitable information.", "In several embodiments, consumer information module 114 can process the information provided from mobile application 123 to provide information to merchant 119 regarding consumer 129.In some embodiments, mobile device 120 can communicate information, such as a buying power index, to point-of-sale terminal 110 and/or merchant 119 upon entering the store of merchant 119.In several embodiments, consumer 129 can decide whether to authorize the transaction using mobile device 120.For example, mobile device 120 can ask consumer 129 to approve the transaction in mobile application 123.In a number of embodiments, mobile application 123 can present the one or more of consumer accounts 131 to consumer 129 to select which of the consumer accounts 131 to use to funds the transaction.", "In some embodiments, consumer 129 can choose to split the funding of the transaction among multiple accounts.", "For example, consumer 129 can choose to fund 20% of the transaction from a demand deposit account (e.g., a debit account) and 80% of the transaction from a non-demand deposit account (e.g., by a charge to a credit account).", "In some embodiments, if an account of the one or more of consumer accounts 131 has an account balance that is less than the amount of the transaction (or the portion of the transaction that consumer 129 has chosen to allocate to the account), loan module 126 of mobile device 120 can determine that there is a deficiency and can present an option to fund the transaction (or a portion of the transaction) using a non-demand deposit account, such as a loan account, a credit account, or a points account.", "In other embodiments, loan module 126 can present the option for funding the transaction through a non-demand deposit account even if there is no deficiency in the one or more of consumer accounts 129.In some embodiments, the loan account can be a new account that is created upon consumer 129 choosing to fund the transaction (or portion thereof) with the loan account.", "In other embodiments, the loan account can be for a previously authorized loan.", "In some embodiments, the loan account can have a pre-existing loan balance, which can be increased based on the amount of loan used to the fund the transaction.", "In several embodiments, the loan can be a small loan, and can be labeled a “micro-loan”), but can be treated the same as credit line for a loan instead of an overdraw of an account.", "In several embodiments, consumer 129 can make the decision from which account or accounts to fund the transaction, and/or to authorize a loan or a credit transaction, while at or near the point-of-sale terminal 110 in the store of merchant 119.In the same or other embodiments, loan module 126 can allow consumer 129 to choose the one or more accounts from which to fund the transaction after consumer 129 has left the store.", "In many embodiments, financial institution 130 can fund the transaction temporarily from a shadow account that the bank uses to fund overdraft transaction, which can be reimbursed from the one or more accounts selected by consumer 129.For example, consumer 129 can authorize a transaction at point-of-sale terminal 110 in the store, and financial institution 130 can authorize transfer of funds to financial institution 150 to pay merchant 119, and after consumer 129 leaves the store of merchant 129, loan module 126 can push a message to consumer 129 asking for one or more of consumer accounts 131 that consumer 129 wants to use to fund the transaction.", "The options of consumer accounts 131 can include the option to open a new loan account, or to add to the balance of an existing loan account.", "In some embodiments, consumer 129 can setup a list (e.g., prioritized list) of consumer accounts 131 to use for transaction using mobile device 120, and/or can setup before-hand an amount and/or percentage to use from one or more of the accounts.", "For example, consumer 129 can choose to use a debit account for the first $50 and then use a credit account for the rest.", "As another example, consumer 129 can choose to use a debit account for 40% of the transaction, and use a new micro-loan for the rest.", "In some embodiments, a points account can be used to pay for all or at least a portion of the payment.", "For example, consumer 129 can have a points account at financial institution 130, which can have a balance of points earned by consumer 129 at financial institution 130.In many embodiments, these points can have an exchange value, such that the points can be redeemed to pay for all or at least a portion of the payment.", "In many embodiments, after mobile device 120 has communicated with point-of-sale terminal 110 using communication module 124 to receive the merchant identifier and other transaction information, and consumer 129 has authorized the transaction, mobile device 120 can communicate with financial institution 130 and/or transaction system 140, either directly or through mobile wallet provider 160, to request a payment be made to merchant account 151 of merchant 119 from one or more of consumer accounts 131.For example, when mobile device 120 communicates with financial institution 130 (either directly or through mobile wallet provider 160) to request a payment be made, account module 134 of financial institution 130 can determine account information about merchant account 151, such as the account identifier of merchant account 151, at least partially based on the merchant identifier received from mobile device 130.In some embodiments, financial institution 130 can communicate with transaction system 140 to get the account information about merchant account 151, which can be stored in merchant account database 141.In some embodiments, financial institution 130 can save the account information about merchant account 151 so financial institution does not need to query the account information from merchant account database 141 in transaction system 140 for future transaction involving the same merchant identifier.", "In other embodiments, financial institution 130 can query for the account information from merchant account database 141 in transaction system 140 for each new transaction, or at occasional and/or regular intervals.", "In other embodiments, when mobile device 120 communicates with transaction system 140 (either directly or through mobile wallet provider 160) to request a payment be made, transaction system 140 can provide the account information about merchant account 151 to first financial institution 130.In many embodiments, having the account information about merchant account 151, financial institution 130 can initiate a payment to financial institution 150 from one or more of consumer accounts 131 to merchant account 151.In several embodiments, before initiating payment, authorization module 133 can determine whether to authorize payment from one or more of consumer accounts 131.For example, financial institution 130 can determine whether the payment amount is within the available funds in one or more of consumer accounts 131, determine whether one or more of consumer accounts 131 is currently open and in good status (or closed), authenticate the identity of consumer 129 using mobile device 120, and/or perform other actions.", "For example, in some embodiments, authentication module 121 can authenticate the identity of consumer 129, and that information can be communicated from mobile device 120 to financial institution 130.In some embodiments, mobile device 120 can prompt consumer 129 to authenticate before and/or after mobile device 120 receives the merchant identifier and/or the transaction information from point-of-sale terminal 110.In some embodiments, authorization module 133 can request additional authentication from authentication module 121 (which can be directly through a network between financial institution 130 and mobile wallet 120, or can be through mobile wallet provider 160 and/or through transaction system 140) after receiving the request for payment from mobile device 120 and/or after receiving the information about merchant 119 and/or merchant account 151.In a number of embodiments, authorization module 133 of financial institution 130 can perform different and/or varying levels of authentication based on various factors.", "For example, authentication module 121 and/or authorization module 133 can determine whether mobile device 120 used to send the request for payment has been previously used by consumer 129 for transaction with financial institution 130, whether biometrics of the consumer match stored biometrics of consumer 129, whether the requested transaction and associated details (e.g., the identity of merchant 119, the location of merchant 119, the payment amount, the one or more items to be purchased (e.g., a list of SKUs), and/or other suitable factors) are consistent with spending patterns of consumer 129, whether consumer 129 has reported mobile device 120 lost or stolen, whether consumer 129 has reported that credit cards, debit cards, or other information about one or more of consumer accounts 131 have been lost or stolen, and/or other suitable factors.", "In various embodiments, financial institution 130 can adjust the level of authentication used to verify the identity of consumer 129 based on one or more of these factors, and/or based on the payment amount, the identity of merchant 119, the location of merchant 119, historical spending of consumer 129, and/or other relevant information.", "In some embodiments, if one or more of consumer accounts 131 chosen by consumer 129 for the transaction is short on funds or otherwise cannot be fully used, loan module 135 can communicate with loan module 126 to present other funding options to consumer 129, such as the option for a micro-loan to fund all or part of the transaction, as described above.", "In many embodiments, after receiving authorization from authorization module 133, financial institution 130 can initiate a payment to financial institution 150 to transfer funds from one or more of consumer accounts 131 to merchant account 151.In a number of embodiments, the payment can be effected by sending payment information regarding a payment to be made to merchant account 151 from one or more of consumer accounts 131.In a number of embodiments, the payment information transferred from financial institution 130 to financial institution 150 can effectuate an authenticated credit push, which can irrevocably satisfy payment to the merchant and/or ensure that the merchant has good funds when consumer 129 leaves the store of merchant 119.For example, the payment can be a settlement credit push of funds for the payment amount from one or more of consumer accounts 131 to merchant account 151, which can be settled immediately.", "In various embodiments, the payment information transferred from financial institution 130 to financial institution 150 can effectuate a push promise to pay, which can provide an irrevocable guarantee of payment from financial institution 130 to financial institution 150.In several embodiments, for example, the payment can be an ACH (Automated Clearing House) credit push, which can provide an irrevocable funding guarantee.", "In many embodiments, the payment and/or the guarantee of payment can be sent in real-time from financial institution 130 to financial institution 150, which can happen for each such transaction.", "In some embodiments, the settlement of the transaction can happen later, such as in a nightly batch fashion, and in some embodiments, can happen through a different network, such as an ACH network or a credit network.", "In other embodiments, the real-time payment and/or guarantee of payment can be processed through an ACH network or a credit network.", "In some embodiments, the consumer can provide instructions to financial institution 130 to label the transaction as a debit or a credit transaction in one or more of consumer accounts 131, and in some embodiments can provide such instructions with the request to pay, or before or after the request to pay.", "In some embodiments, a credit transaction can be treated as a micro-loan, as described above.", "In certain embodiments, a debit pull with guaranteed promise to pay can be used, such that financial institution 150 can receive a guaranteed promise to pay from financial institution 130 and pull the funds using a debit pull.", "In various embodiments, transaction system 140 can store information regarding each transaction in transaction database 142.In several embodiments, transaction system 140 can serve as a central auditor for transactions between the financial institutions (e.g., 130, 150) in data communication with transaction system 142.In some embodiments, transaction system 140 can receive some or all of the information from the merchant security transaction code.", "In various embodiments, one or more portions of the merchant security transaction code can be encrypted by security module 115.For example, the merchant security transaction code can include an encrypted portion that can be decrypted by security module 146 of transaction system 140, which can be used to ensure that the message has not been tampered.", "In other embodiments, the merchant security transaction code is not encrypted, but is digitally signed, as described above, and the digital signature can be verified, in some embodiments, by security module 146, which can advantageously ensure that the merchant identifier correctly identifies merchant 119, so that the funds are paid to merchant account 151 corresponding to merchant 119.In a number of embodiments, financial institution 150, upon receiving payment and/or guarantee of payment, can notify point-of-sale terminal 110 and/or merchant 119 in real-time that merchant 119 has satisfactorily received payment from consumer 129.For example, the notification can include various information, such as the transaction identifier, the amount received in payment (or guarantee), the merchant identifier, and/or other information.", "Receiving the notice of good funds can allow merchant 119 to proceed, such as, for example, to allow consumer to leave the store of merchant 119 with the items.", "In some embodiments, for example, point-of-sale terminal 110 can match the notification to the pending transaction in point-of-sale terminal 110 using the transaction identifier.", "In certain embodiments, merchant 119 can match the notification to the point-of-sale terminal using the merchant identifier.", "In some embodiments, consumer 129 can receive a notification on mobile device 120 that the transaction has cleared, such as shown in FIG.", "22 and described below.", "In several embodiments, system 100 can advantageously provide a number of technological improvements that can overcome technological problems in conventional systems.", "For example, in several embodiments, system 100 can beneficially allow consumer 129 to send payment directly and/or immediately to merchant 119 when consumer 129 is checking out at point-of-sale terminal 110.In many embodiments, the payment systems and methods provided by system 100 described herein can eliminate the acquirer model that is conventionally used in payment card transactions.", "In several embodiments, the payment systems and methods provided by system 100 described herein can advantageously streamline payments by eliminating the need for the financial institution (i.e., the acquirer) of merchant 119 to request payment from the financial institution (i.e., the issuer) of consumer 129.For example, in many embodiments, financial institution 150 does not need to request payment from financial institution 130.In many embodiments, the payment systems and methods provided by system 100 described herein can beneficially ensure merchants (e.g., merchant 119) are paid by consumers (e.g., consumer 129) while eliminating and/or reducing many of the transaction fees paid to various entities in the conventional model.", "In a number of embodiments, the payment systems and methods provided by system 100 described herein can advantageously eliminate the chargeback liability of merchants for fraudulent transactions.", "In the conventional acquirer-issuer model, the merchant (e.g., 119) is responsible for verifying the credit or debit card to ensure that the card is not being used fraudulently.", "In several embodiments, the payment systems and methods provided by system 100 described herein can beneficially place the liability on the financial institution (e.g., 130) of the consumer (e.g.", "129), which can be in a better position (e.g., with more and/or better information) than the merchant (e.g., 119) to determine if the request to pay is a legitimate, authentic transaction requested by the consumer (e.g., 129) and/or if the consumer's account is still open and in good status (or closed), has sufficient funds, etc.", "In various embodiments, the payment systems and methods provided by system 100 described herein can advantageously allow the financial institution (e.g., 130) of the consumer (e.g., 129) to choose how to authenticate the consumer (e.g., 129), and/or can beneficially allow the financial institution (e.g., 130) of the consumer (e.g., 129) to choose the level of authentication, which can be tailored for each consumer (e.g., 129) and/or for each transaction (e.g., the financial institution (e.g., 130) can decide, at least partially based on its risk determination, that a transaction with a higher payment amount warrants a higher level of authentication).", "In several embodiments, the liability for fraudulent use of one or more of the consumer accounts (e.g., 131) can be placed on the consumer (e.g., 129), and/or the consumer (e.g., 129) can choose the level of authentication used by the financial institution (e.g., 130) of the consumer (e.g., 129).", "In many embodiments, unauthorized access to one or more of consumer accounts 131 can beneficially be reduced and/or eliminated using the payment method

understood that this disclosure is not limited to particular embodiments described, as such may, of course, vary.", "It is also to be understood that the terminology used herein is for the purpose of describing particular embodiments only, and is not intended to be limiting, since the scope of the present disclosure will be limited only by the appended claims.", "Where a range of values is provided, it is understood that each intervening value, to the tenth of the unit of the lower limit unless the context clearly dictates otherwise, between the upper and lower limit of that range and any other stated or intervening value in that stated range, is encompassed within the disclosure.", "The upper and lower limits of these smaller ranges may independently be included in the smaller ranges is also encompassed within the disclosure, subject to any specifically excluded limit in the stated range.", "Where the stated range includes one or both of the limits, ranges excluding either or both of those included limits are also included in the disclosure.", "Unless defined otherwise, all technical and scientific terms used herein have the same meaning as commonly understood by one of ordinary skill in the art to which this disclosure belongs.", "Although any methods and materials similar or equivalent to those described herein can also be used in the practice or testing of the present disclosure, the preferred methods and materials are now described.", "All publications mentioned herein are incorporated herein by reference to disclose and describe the methods and/or materials in connection with which the publications are cited.", "It must be noted that as used herein and in the appended claims, the singular forms “a”, “an”, and “the” include plural referents unless the context clearly dictates otherwise.", "The publications discussed herein are provided solely for their disclosure prior to the filing date of the present application.", "Nothing herein is to be construed as an admission that the present disclosure is not entitled to antedate such publication by virtue of prior disclosure.", "Further, the dates of publication provided may be different from the actual publication dates which may need to be independently confirmed.", "As will be apparent to those of skill in the art upon reading this disclosure, each of the individual embodiments described and illustrated herein has discrete components and features which may be readily separated from or combined with the features of any of the other several embodiments without departing from the scope or spirit of the present disclosure.", "The figures shown herein are not necessarily drawn to scale, with some components and features being exaggerated for clarity.", "The analyte sensor may be configured so that at least a portion thereof is placed under the skin of the patient to detect the analyte levels of the patient, and another portion of the analyte sensor—which may be above the skin—is coupled to electronics within a housing that is positioned externally on the skin of the subject.", "The electronics may include various components, such as communication element(s) for communication with a remote receiving unit.", "The analyte monitoring device that is coupled to the subject's body and includes the in vivo positioned analyte sensor, housing, and electronics (e.g., data processing, storage, and/or communication components) is also referred to herein as an “on-body unit”, “OBU”, “on-body sensor”, “on body patch”, or “patch”.", "Analyte sensors may have temperature dependencies and the sensor signals produced by the sensors may then be affected by temperature changes.", "An error caused by temperature may lead to an associated error in analyte measurements, such as glucose measurements.", "It should be appreciated the subject matter of the disclosure is not limited to transcutaneous analyte sensor, but is also applicable to in vivo analyte sensors in general.", "Temperature Compensation As summarized above, aspects of the present disclosure relate to analyte monitoring systems, devices, and methods thereof related to temperature compensation.", "It should be appreciated that while the devices and methods may be described in terms of a subcutaneous sensor, other in vivo analyte sensors may also be applicable and the subject matter not limited to specifically subcutaneous analyte sensors.", "It should also be appreciated that the embodiments described herein are exemplary and should not be viewed as limiting.", "For example, it should be appreciated that the methods described herein may be implemented in an on-body unit, the receiver, or mixed between the on-body unit and the receiver.", "Thus, various combinations of the steps performed on the on-body unit or receiver are contemplated.", "For example, an on-body unit may perform some steps such as temperature measurement and transmit the measurement to a receiver, where a processor on the receiver performs subsequent processing, such as determining ambient temperature compensation, determining temperature-compensated analyte sensor signals, determining analyte levels, etc.", "Or, as another example, the on-body unit may perform the steps of measuring the temperature, determining ambient temperature compensation, and determining temperature-compensated analyte sensor signals.", "For instance, the on-body unit may transmit the results to a receiver wherein the results are provided on a user interface.", "It is noted that the combinations of steps between the on-body unit and receiver are appreciated for the one temperature sensor and two temperature sensor embodiments.", "Thus, for example, steps in the two temperature sensor embodiments may also be performed on the on-body unit or the receiver in other embodiments—e.g., sampling of temperature sensors, and/or correction factor or gain determination, determining ambient temperature compensation, determining temperature-compensated analyte sensor signals, etc.", "It is also appreciated that temperatures may be measured by a processor on the on-body unit and/or receiver.", "For example, a processor may receive temperature data from a temperature sensor and calculate a temperature from the temperature data.", "The temperature may be, for example, an analog or digital signal derived by the temperature sensor.", "For example, in certain embodiments, a processor on the on-body unit may be coupled to the temperature sensor and provide a temperature measurement to the receiver, wherein the receiver detects the temperature measurement communicated and then performs additional processing steps based on the temperature measurement.", "It is appreciated that in another embodiment, the temperature data from the temperature sensor is sent to the receiver and the processor on the receiver calculates the temperature from the temperature data.", "The processor may then use this detected temperature for additional processing steps.", "Compensating Sensor Signals Temperature measurements are important for obtaining accurate analyte measurements (e.g., glucose measurements) with on-body sensors that are part of in vivo analyte monitoring systems—e.g., continuous glucose monitor (CGM) systems or intermittent or periodic glucose monitoring systems.", "The analyte-sensing chemistry on a subcutaneously positionable analyte sensor, or other in vivo analyte sensor, of the on-body sensor is temperature dependent and the sensor signal produced by the in vivo analyte sensor is thus affected by temperature.", "Subcutaneously inserted glucose sensors, for example, may measure glucose by correlating the sensor signal output with glucose concentration.", "The signal response of analyte sensor may be linear across the operating range of glucose concentrations.", "However, the slope of this response may vary as temperature around the analyte sensor tip changes.", "In order to compensate for this thermal effect, knowledge of temperature around the sensor sensing area is needed.", "The term “sensing area” is used herein to mean the area of the analyte sensor where the sensing chemistries are located.", "For example, in certain embodiments, the sensing area is disposed at the sensor tip, and thus the temperature at the sensor tip is estimated.", "Therefore, the effect of temperature may be taken into account in order to calculate an accurate value for glucose concentration.", "On-body sensors may utilize a temperature sensor disposed near the in vivo analyte sensor to estimate the sensor temperature.", "This temperature measurement is used to compensate the analyte sensor signal for temperature effects.", "For example, temperature-compensated analyte sensor signal may be determined by: ITC=I*1.07̂(32.5−T), where I is the raw sensor current, T is the measured temperature in degrees Celsius (C), and ITC is the temperature compensated signal that is proportional to glucose concentration.", "Ambient temperature impinging on the on-body housing may influence temperature measurements, and in effect, create a temperature measurement error that will lead to a glucose calculation error.", "For example, in some instances, experiments have shown that in an ambient temperature environment of 20 degrees C., the resulting glucose error due to ambient temperature effects can be about 10%.", "In some aspects of the present disclosure, on-body sensors employ a second temperature sensor used to compensate for errors in the sensor temperature measurement due to the influence of ambient temperature on the first temperature sensor.", "For example, one temperature sensor (T1) may be located close to the skin surface Tskin, and another temperatures sensor (T2) located close to the transmitter (TX) processor or on the printed circuit board (PCB).", "The temperature which compensates for ambient temperature influence using two temperature sensors is determined by, for example: T=T1+K*(T1−T2) where K is related to the thermal resistances between the first temperature sensor and the second temperature sensor, and is a constant (e.g., 0.5, 0.2, or other constant) that may be derived empirically; T1 is the measured temperature at the temperature sensor near the sensor; T2 is the measured ambient temperature from the second temperature sensor; and T is the temperature which is compensated for ambient temperature influence.", "Other more complex models may be contemplated; for instance, K may not be constant but rather a function of T1 and/or T2, for instance.", "Ambient Temperature Compensation Using a Single Temperature Sensor To estimate the temperature at the sensing area of the in vivo analyte sensor, ambient compensation may be performed.", "In some aspects of the present disclosure, ambient temperature compensation is provided using a single temperature sensor on the on-body sensor.", "Thus, a second temperature is not required to compensate for ambient effects.", "Having a single temperature instead of multiple temperature sensors may provide one or more benefits, such as a reduction in cost, a reduction in complexity, etc.", "FIG.", "5 illustrates a flowchart for a method of determining an analyte level by compensating for ambient temperature using a single temperature sensor (e.g., a temperatures sensor that approximates skin temperature) on an on-body sensor, according to certain embodiments.", "At block 601, a sensor signal is received from an in vivo analyte sensor that is transcutaneously positioned with the skin of a subject.", "For example, the on-body sensor may include a processor that is electrically coupled to the analyte sensor and receives the sensor signal.", "At block 605, the processor receives a temperature signal from a temperature sensor coupled to the on-body sensor.", "The temperature sensor may be, for example, positioned at or near a skin contacting surface to represent skin temperature.", "Since skin temperature may be affected by ambient temperature, a change in skin temperature may be correlated to a change in ambient temperature.", "When the ambient temperature is low, skin temperature will decrease, and when the ambient temperature is high, skin temperature will increase.", "Thus, deviations from “normal” skin temperature may be used to represent how strong the ambient temperature effects are.", "At block 610, the processor determines if the measured temperature has reached a predetermined threshold value.", "For instance, a normal temperature or normal temperature range may be established and any deviation past the established threshold or thresholds (e.g., outside the normal temperature range) will trigger the ambient temperature correction.", "It should be appreciated that the term “predetermined threshold” is used broadly herein, and may include an upper and lower threshold.", "For example, an upper threshold and lower threshold may be implemented in some instances to establish a range.", "In some instances, only an upper or lower threshold may be implemented.", "If the skin temperature does not deviate beyond the threshold, then it can be assumed that the ambient temperature effects are minimal, and no ambient temperature compensation is required, as represented by block 615.The temperature measurement may then be used to determine the temperature compensated analyte sensor signal, ITC, as represented by block 625, and transmitted or displayed as a corresponding analyte (e.g., glucose) level, as represented by block 630.If the skin temperature deviates beyond the predetermined threshold, then it can be assumed that the ambient temperature effects are significant, and ambient temperature compensation is performed (e.g., a correction factor applied) to compensate for the effects of ambient temperature, as represented by block 620.The resulting ambient-compensated temperature is then used to determine the temperature-compensated analyte sensor signal, ITC, as represented by block 625, for a more accurate analyte (e.g., glucose) level determination that is transmitted or displayed, as represented by block 630.For example, skin temperature for most people may normally range between 30 and 35° C. in ambient temperature environments that people are comfortable in.", "In certain embodiments, ambient temperature compensation is applied when “extreme” skin temperatures are detected (e.g., when the skin temperatures deviate beyond the predetermined threshold or thresholds).", "For instance, when the skin temperature measurement from the temperature sensor drops below 30 degrees C., then a correction factor can be added to the temperature measurement.", "It should be appreciated that the predetermined threshold or thresholds (e.g., the “normal” range) may vary, and further, that the actual compensation algorithm (e.g., correction factor) implemented may also vary.", "As an example, ambient temperature compensation may be provided by the correction factor: If T<30, then Tcorrected=T+1 AND IF T>35, then Tcorrected=T−1 As another example, the ambient temperature compensation may be provided by a slightly more complex correction factor, such as: If T<30, then Tcorrected=T+(30−T)/5 AND If T>35, then Tcorrected=T−(T−35)/5 Tcorrected is then used to determine the temperature-compensated analyte sensor signal.", "In this way, the temperature-compensated analyte sensor signal accounts for ambient temperature influence.", "It should be appreciated that correction factors of varying complexities may be implemented in other embodiments.", "It should be appreciated that illness may also affect the skin temperature of a subject—e.g., to make the skin temperature elevate outside the normal range.", "In certain embodiments, the ambient temperature compensation is applied only if the temperature error causes a high reading.", "In this way, only low temperature measurements are compensated.", "In certain embodiments, changes in skin temperature are used to detect and correct for ambient temperature influences.", "For example, an ambient correction factor may be applied after a change in skin temperature is detected.", "It should be appreciated that the magnitude of the change may vary in different implementations as desired.", "For example, in some instances, a “normal” temperature could be detected at the start of a sensor wear, and when the temperature deviates by some predetermined amount (or, for example, by an amount detected by monitoring the changes during a period at the start of a sensor wear), then the ambient temperature compensation can be performed, such as described above.", "In certain embodiments, temperature changes above a certain absolute value over a predetermined period of time initiates the ambient temperature compensation.", "For instance, T(t=0)−T(t=−10)>5, then Tcorrected=T+1 T(t=0)−T(t=−10)<−5, then Tcorrected=T−1 In certain embodiments, the ambient temperature compensation is based on the rate of change of skin temperature.", "In other embodiments, a combination of absolute temperature checks and temperature rate of change could be used in both the detection and correction.", "It should be appreciated that the embodiment shown in FIG.", "5 is exemplary, and that one or more steps may be performed by a processor on the on-body unit and/or a receiver in communication with the on-body unit in other embodiments.", "For example, in certain embodiments, the temperature sensor is coupled to the on-body unit and a processor on the on-body unit is detecting the temperature measurement, determining whether the threshold requirement is met, performing the ambient temperature compensation, and determining the temperature-compensated signal.", "Then, for example, the temperature-compensated signal is sent to a receiver wherein the temperature-compensated analyte level is displayed on a user-interface of the receiver for instance.", "In another embodiment, for example, the temperature sensor is coupled to the on-body unit and a processor on the on-body unit transmits the temperature measurements to the receiver where a processor coupled to the receiver determines whether the threshold requirement is met, performs the ambient temperature compensation, and determines the temperature-compensated signal.", "Then, for example, the temperature-compensated analyte level is displayed on a user-interface of the receiver for instance.", "It should be appreciated that the steps may be split up in other combinations between the on-body unit and the receiver.", "It should be appreciated that, in certain embodiments, the ambient temperature compensation may, for the most, always or continuously be performed on the received analyte sensor signal.", "For example, the processor may continuously perform the ambient temperature compensation on the analyte sensor signal in addition to determining if the threshold temperature has been exceeded.", "When the temperature measurement does not exceed the temperature threshold, the temperature-compensated analyte sensor signal is based off the uncompensated signal, resulting in uncompensated analyte levels.", "When the temperature measurement exceeds the temperature threshold, the temperature-compensated analyte sensor signal is based off the ambient-compensated signal, resulting in ambient-compensated analyte levels.", "Thus, the temperature-compensated analyte sensor signal results in a mixed signal of the uncompensated analyte levels and ambient-compensated analyte levels.", "The temperature-compensated analyte sensor signal may be transmitted (e.g., communicated to a receiver) or presented on a user interface (e.g., displayed on a display for the user).", "In other embodiments, the ambient-temperature compensation is not always or continuously performed on the received analyte sensor signal, but rather, only when the temperature threshold is exceeded.", "When the temperature measurement does not exceed the temperature threshold, the temperature-compensated analyte sensor signal is based off the uncompensated signal, resulting in uncompensated analyte levels presented on a user interface (e.g., displayed on a display).", "When the temperature measurement exceeds the temperature threshold, ambient-compensation is performed and the temperature-compensated analyte sensor signal is based off the ambient-compensated signal, resulting in ambient-compensated analyte levels presented on the user interface.", "Again, the temperature-compensated analyte sensor signal results in a mixed signal of the uncompensated analyte levels and ambient-compensated analyte levels.", "It is also appreciated that in certain embodiments, the ambient compensation may be based off predetermined temperature ranges rather than predetermined thresholds.", "For example, the uncompensated analyte sensor signal may be used when the temperature measurement falls within a predetermined range or ranges, and the ambient compensated signal is used when the temperature measurement falls within another predetermined range or ranges.", "It should be appreciated that in certain embodiments the temperature compensation may be applied to an analyte sensor signal that is not yet calibrated or converted (e.g., scaled by a scaling factor) to a corresponding analyte level, and thereafter converted to the corresponding analyte level.", "In yet other embodiments, the temperature compensation is applied to an analyte sensor signal that already represents the analyte level (e.g., is already calibrated or converted to the corresponding analyte level), and the temperature-compensated analyte sensor signal is the temperature compensated analyte level.", "Ambient Temperature Compensation Based on Core Body Temperature As previously noted, some on-body units may include a correction algorithm that utilizes two temperatures sensors to compensate for ambient temperature influence on the temperature sensor.", "For example, one temperature sensor is located close to the skin in a can that protrudes from the bottom of the transmitter.", "The other temperature sensor is located on the printed circuit board (PCB) in the transmitter and is a feature provided by the controller chip.", "Again, the correction method employed is: T=T1+K*(T1−T2) This method can be considered an “extrapolation” method, since two temperature measurements are made at points where the temperature for each is lower than the sensing area temperature, and the sensing area temperature is estimated by extrapolating from these two measured temperatures.", "In this transmitter configuration, the two temperature sensors are generally well separated, which results in a stable K value that is robust over different transmitter locations on the body and for different body types.", "As transmitter designs become physically smaller, however, it becomes more difficult to separate the two temperature sensors thermally.", "Without adequate thermal separation, the K value becomes significantly less stable, and furthermore, becomes significantly larger, with the effect of amplifying the noise in the temperature measurement.", "Utilizing a single temperature sensor instead of two may provide many advantages, such as cost savings.", "In some aspects of the present disclosure, ambient temperature compensation is based on a predetermined core body temperature and temperature measurements from a single temperature sensor.", "FIG.", "6 illustrates a flowchart for a method of compensating for ambient temperature using a single temperature sensor on an on-body unit, according to certain embodiments.", "At block 701, a sensor signal is received from an analyte sensor that is transcutaneously positioned within the skin of a subject, or otherwise implanted in vivo.", "For example, the on-body unit may include a processor that is electrically coupled to the analyte sensor and receives the analyte sensor signal.", "At block 705, the processor receives temperature data from a temperature sensor coupled to the on-body unit.", "For example, in certain embodiments, the temperature sensor may be positioned at or near a skin contacting surface to represent skin temperature.", "At block 710, the processor determines an ambient-compensated temperature from the measured temperature using an offset term (e.g., an offset term based on a predetermined core body temperature).", "For example, a correction factor is applied to the measured temperature to correct for ambient temperature effects.", "The correction factor may have an offset term that is based on a predetermined core body temperature value—e.g., 37° C. since a user's core body temperature is relatively stable at approximately 37° C. For example, ambient temperature compensation may be provided by the following correction factor: Test=Bcorebody K*T1 where Bcorebody is a predetermined core body temperature (e.g., approximately 37 degrees C.); K is a constant that may be empirically derived; and T1 is the measured temperature by the temperature sensor; and Test is the estimated sensing area temperature that is compensated for ambient temperature influence.", "The resulting sensing area (e.g., sensor tip) temperature estimate is compensated for ambient effects and may then be used to determine the temperature-compensated analyte sensor signal, ITC, as represented by block 715, for a more accurate glucose level determination that is transmitted or displayed, as represented by block 720.The sensing area temperature estimate is an “interpolation” method since the sensing area temperature estimate is in between the core body temperature and the temperature measured at the transmitter.", "Measurement noise is not amplified using the interpolation method.", "As similarly stated above, it should be appreciated that the embodiment shown in FIG.", "6 is exemplary, and that one or more steps may be performed by a processor on the on-body unit and/or a receiver in communication with the on-body unit in other embodiments.", "For example, in certain embodiments, the temperature sensor is coupled to the on-body

indicates that the user has entered a hyperglycemic state.", "As another example, a datapoint which correlates to a glucose level of 65 mg/dL exceeds a threshold value for hypoglycemia of 70 mg/dL because the datapoint indicates that the user is hypoglycemic as defined by the threshold value.", "However, a datapoint which correlates to a glucose level of 75 mg/dL would not exceed the same threshold value of 70 mg/dL for hypoglycemia because the datapoint does not indicate that particular condition as defined by the chosen threshold value.", "An alarm may also be activated if the sensor readings indicate a value that is outside of (e.g., above or below) a measurement range of the sensor.", "For glucose, the physiologically relevant measurement range may be 30-400 mg/dL, including 40-300 mg/dL and 50-250 mg/dL, of glucose in the interstitial fluid.", "The alarm system may also, or alternatively, be activated when the rate of change or acceleration of the rate of change in analyte level increase or decrease reaches or exceeds a threshold rate or acceleration.", "For example, in the case of a subcutaneous glucose monitor, the alarm system may be activated if the rate of change in glucose concentration exceeds a threshold value which may indicate that a hyperglycemic or hypoglycemic condition is likely to occur.", "In some cases, the alarm system is activated if the acceleration of the rate of change in glucose concentration exceeds a threshold value which may indicate that a hyperglycemic or hypoglycemic condition is likely to occur.", "A system may also include

longitudinal sections of another sample embodiment of a compression chamber with mounted valve unit and piston rod driven like a connecting rod in various positions of use.", "DETAILED DESCRIPTION According to FIG.", "1, a compressor P according to the invention has a motor 1, which is cooled by a fan 2.On a motor shaft not otherwise shown there sits a transmission gear 3, which interacts with a power takeoff gear 4.The power takeoff gear 4 is eccentrically connected to a piston rod 5, which moves a piston 6 (FIG.", "3) in a compression chamber 7.Mounted on this compression chamber 7 is a valve unit 8, which has a pipeline 9 to a tire, for example, and a connection 10 to a container for tire sealant, for example.", "The mode of operation of this compressor is as follows: The transmission gear 3 is placed in rotary motion by the motor 1 and transfers its rotary motion to the power takeoff gear 4.This, in turn, moves the piston rod 5 in the compression chamber 7, as is shown in particular in FIGS.", "9 to 12.In this way, air is forced from the compression chamber 7 into the valve unit 8 and into the pipeline 9.Then, across the connection 10, a medium, especially a tire sealant, is either sucked out from a not otherwise shown container or forced additionally into the pipeline 9 and thus brought for example into a tire being sealed.", "A portion of the present invention pertains to an improvement of the power transmission of the power of the motor 1 to the piston rod 5 or the piston 6.It is known that more power is needed for compressing the air in the compression chamber 7 than when sucking new air into the compression chamber.", "In order to deal with this power relationship, preferably both the transmission gear 3 and the power takeoff gear 4 are designed as two-part.", "The transmission gear 3 consists of two gears 11 and 12, lying one against the other and having a congruent opening 13 to receive a motor shaft.", "Moreover, the gear 11 also has a larger diameter than the gear 12.The power takeoff gear 4 consists of two halves 4.1 and 4.2.Each half is occupied by a toothing 14.1 and 14.2.Each toothing 14.1 and 14.2 extends over only one half circle of the particular power takeoff half gear 4.1 and 4.2, while the other half is free of toothing.", "Here as well, it is provided that the power takeoff half gear 4.2 with the toothing 14.2 has a larger diameter than the power takeoff half gear 4.1 with the toothing 14.1.The gear 12 with the smaller diameter interacts with the power takeoff half gear 4.2 with the larger diameter, while the gear 11 with the larger diameter interacts with the power takeoff half gear 4.1 with the smaller diameter.", "As soon as the gear 12 with the smaller diameter engages with the toothing 14.2 of the power takeoff half gear 4.2, the transmission ratio can therefore apply a greater force, so that this engaged state is preferred when a larger force needs to be acting on the piston 6 during the compressing.", "When the piston 6 returns to suctioning of new air into the compression chamber 7, the gear 11 with the larger diameter is then in engagement with the toothing 14.1 of the power takeoff gear 4.1 with the smaller diameter.", "A further notion of the invention pertains to the arrangement of valve unit and compression chamber.", "In FIGS.", "5 and 6 a valve unit 8.1 is shown which is mounted on a compression chamber 7.1 in bayonet fashion.", "For this, the compression chamber 7.1 has a collar 15, which is provided with a locking element.", "This locking element surrounds a connection opening 16 between valve unit 8.1 and compression chamber 7.1.Next comes a shoulder 18 on a deep indentation 17, adjoined by an end stop 19.The valve unit 8.1, in turn, has at least one vane 20, from which a hook-like molding 21 projects downward.", "For the assembly process, the valve unit 8.1 is placed on top of the collar 15, while the molding 21 travels across the deep indentation 17.Now the valve unit 8.1 is turned relative to the annular collar 15, so that the hook-like molding 21 travels across the shoulder 18 and reaches under a hook 22.The rotation can then occur as far as the end stop 19.This results in the assembly position shown in FIG.", "6.In one sample embodiment of the invention, which is shown especially in FIG.", "7, a seal is arranged between the compression chamber 7.1 and the valve unit 8.1 in the region of the connection opening 16, being shaped like a discus in this sample embodiment.", "Corresponding air openings 24 are then configured as oblong holds.", "When compressed air is delivered from the compression chamber 7.1, the edges of the disk-like seal 23 are lifted in particular.", "In another sample embodiment of the seal between compression chamber 7.2 and valve unit 8.2 according to FIGS.", "9 to 12, the seal is designed as a shuttlecock.", "This shuttlecock seal 25 moves in a chamber 26 of the valve unit 8.2 from an opening position to a closed position depending on whether air is being brought in from the compression chamber 7.2 or needs to be drawn into the compression chamber 7.2.The notion of the invention which is shown in FIGS.", "7 and 8 contributes to a further improvement.", "Here, the pipeline 9 downstream from the connection 10 to the container for tire sealant is provided with a Venturi-type constriction 27.This Venturi-type constriction 27 has the purpose of accelerating the air flow, which increases the partial vacuum in the pipeline 9, so that an increased suction of tire sealant from the container occurs.", "In order to further improve this, the connection 10 extends for a certain extent axially in trunk-like manner along the pipeline 9." ] ]

bleached wood fluff pulp and a SAP (Super Absorbent Polymer) mixture for the absorbent core.", "At low ratios of 30% or less SAP to pulp ratio, the core mixture may or may not be wrapped in an absorbent tissue to prevent the SAP from falling apart or out of the core.", "At higher levels of SAP at 50% or more, the core must be wrapped to prevent the loose SAP from being shaken out.", "Also a core adhesive may be added to prevent the heavier SAP particles from being separated from the fluff pulp fibers.", "This is the most advanced technology of today that is employed in infant sized disposable absorbent products.", "The pulp fiber in these products is required to rapidly manage the body fluid exudates until the SAP can desorb the fluff fibers to prepare the fluff fibers for the next exudates.", "For an infant, their body can produce up to 150 ml (grams) of urine and deliver it into the absorbent core over about 70 seconds.", "This delivery rate starts off rapidly and can achieve approximately 10 to 15 ml per second after the first 5 seconds or so and then trail down to zero.", "For an adult the amount of exudate is much larger and can easily exceed 300 ml or more delivered over a time period of more than 70 seconds at a rate similar or less than what infants void.", "A significant problem with the current absorbent products that contain wood fluff pulp or even wrapped with a tissue or airlaid is in all cases their construction results in a core which feels wet against the body after it has received the voided fluid(s).", "This wetness feeling is akin to the feeling of wearing a cotton T-Shirt, getting it wet and then continuing to wear the wet cotton T-Shirt long after it should have been changed to a drier shirt.", "To address this wet feel, almost all current absorbent product designs employ a distancing layer of synthetic fibers on top of the “wet core” as an attempt to create a “feel drier” layer.", "This synthetic distancing layer is often called a “fluid transfer layer”, “fluid acquisition layer”, or “acquisition distribution layer (ADL)” and is typically much smaller than the core that it covers, leaving the edges of the core exposed.", "Moreover, despite their design goal, such fluid acquisition layers only work to a limited degree.", "In this regard as the exudate leaves the body at 98 degrees Fahrenheit it quickly drops to about 90 degrees Fahrenheit as it enters the core of the absorbent product.", "This creates a cooling effect when touched by the skin, which may increase during the time worn.", "If left on for an extended period of time, the wet product will achieve a thermal equilibrium and equilibrate somewhere between room temperature and about 90 degrees Fahrenheit, depending upon ambient temperature and clothes worn.", "This difference can be further exacerbated depending upon the thermal conductivity of the materials chosen to absorb the exudate.", "But in all cases current wood pulp fluff absorbent products will feel wet and/or cold to the skin the longer the product is worn.", "The current state of the art product design for the synthetic absorbent cores is based upon a synthetic continuous fiber matrix inter-layered with superabsorbent particles (SAP).", "For example a polypropylene tow fiber similar to tow used in cigarette filter making was chosen.", "This material is purchased in a continuous form and is pulled out of the box and proceeds into an air trumpet or similar device or the like, to expand the fiber tow matrix.", "Then SAP particles are intermixed, adhesive is sprayed into the fiber SAP matrix and the entire matrix is wrapped to result in what is the state of the art of current “Pulpless” core technology.", "This type of core has the major limitations of a slow absorbency rate.", "That rate is highly dependent upon the SAP chosen and on the adhesive type and amount required to attach the SAP to the tow fiber matrix.", "For example, if enough adhesive is provided to ensure that the SAP remains in its desired location within the core, that adhesive may limit the SAP's absorbent swelling due to coating part of the SAP particles.", "If less adhesive is utilized, while it may permit greater swelling and absorption of the exudate by the SAP, it may allow the SAP particles to fall from their positions in the core to the bottom of the crotch area, rendering it heavier and wetter in the crotch area when voided into and less absorbents at the ends.", "Another example of current pulpless core technology is gluing the SAP to the back sheet or inside the top or body facing sheet.", "This bonding process may limit the SAP from being fully expanded and utilized in absorbing the exudate.", "When bonded in such a matter, the SAP may be also be applied in continuous rows to provide space for the fluid to travel unhindered.", "Or the SAP may be intermixed with ground wood pulp fibers of similar size to enhanced fluid movement in this inefficient design.", "Current SAP limitations require having to choose between a higher absorbent capacity, with the disadvantage of having slower speed, or a faster SAP with less absorbing capacity.", "If the current SAPs are mixed, the fast acting SAP will very rapidly swell and may “gel-block” the slower acting, but higher absorption capacity SAP.", "If gel-blocking occurs, it will limit, or even prevent, the higher capacity SAP from desorbing the faster but lower capacity SAP.", "In the past a cellulose acetate fiber core with a single SAP has been developed and commercially available, as has a non-SAP version.", "Current polypropylene filament tow technology has also been used for the absorbent cores.", "In this regard, such polypropylene tow cores used in the market today make use of round or oval homo-polymer polypropylene fibers, which provide minimal resistance to fluid flow through the SAP/tow fiber matrix, thereby only providing minimal dwell time for the fluid to be absorbed by the SAP.", "While such prior art absorbable products containing wood fluff pulp are generally suitable for their intended purposes, they still leave much to be desired.", "In particular, the thickness of today's disposable absorbent products containing wood fluff pulp and the state of the art in pulp fiberizing technology result in an absorbent product that is significantly thicker than current cotton underwear.", "This results in a thicker product on the body which may not allow normal clothes or their usual size normal clothing to be worn.", "In addition the increased thickness of such products results in increased storage, transportation and handling costs and increased retail display space.", "In our aforementioned patent application there is disclosed and claimed a disposable absorbent garment, which overcomes many of the disadvantages of art absorbable products containing wood fluff pulp.", "In particular, that patent application discloses an exemplary absorbent assembly comprising a core formed of a synthetic tow or of synthetic nonwoven layers and having first section comprising a slow acting but high absorption capacity SAP and a second section comprising a fast acting but lower absorption capacity SAP, all of which is wrapped in a wrapper to hold the SAP in place.", "The absorbent assembly may be quilted and corrugated.", "The undergarment also includes releasably securable fasteners to enable it to be readily removed and a suspension system to ensure that the garment fits properly and doesn't leak even when holding a large amount of exudate.", "Odor removal/masking and treatment features may be provided.", "It addition the undergarment may include a wetness indicator.", "The subject invention is

an absorbent tissue to prevent the SAP from falling apart or out of the core.", "At higher levels of SAP at 50% or more, the core must be wrapped to prevent the loose SAP from being shaken out.", "Also a core adhesive may be added to prevent the heavier SAP particles from being separated from the fluff pulp fibers.", "This is the most advanced technology of today that is employed in infant sized disposable absorbent products.", "The pulp fiber in these products is required to rapidly manage the body fluid exudates until the SAP can desorb the fluff fibers to prepare the fluff fibers for the next exudates.", "For an infant, their body can produce up to 150 ml (grams) of urine and deliver it into the absorbent core over about 70 seconds.", "This delivery rate starts off rapidly and can achieve approximately 10 to 15 ml per second after the first 5 seconds or so and then trail down to zero.", "For an adult the amount of exudate is much larger and can easily exceed 300 ml or more delivered over a time period of more than 70 seconds at a rate similar or less than what infants void.", "A significant problem with the current absorbent products that contain wood fluff pulp or even wrapped with a tissue or airlaid is in all cases their construction results in a core which feels wet against the body after it has received the voided fluid(s).", "This wetness feeling is akin to the feeling of wearing a cotton T-Shirt, getting it wet and then continuing to wear the wet cotton T-Shirt long after it should have been changed to a drier shirt.", "To address this wet feel, almost all current absorbent product designs employ a distancing layer of synthetic fibers on top of the “wet core” as an attempt to create a “feel drier” layer.", "This synthetic distancing layer is often called a “fluid transfer layer”, “fluid acquisition layer”, or “acquisition distribution layer (ADL)” and is typically much smaller than the core that it covers, leaving the edges of the core exposed.", "Moreover, despite their design goal, such fluid acquisition layers only work to a limited degree.", "In this regard as the exudate leaves the body at 98 degrees Fahrenheit it quickly drops to about 90 degrees Fahrenheit as it enters the core of the absorbent product.", "This creates a cooling effect when touched by the skin, which may increase during the time worn.", "If left on for an extended period of time, the wet product will achieve a thermal equilibrium and equilibrate somewhere between room temperature and about 90 degrees Fahrenheit, depending upon ambient temperature and clothes worn.", "This difference can be further exacerbated depending upon the thermal conductivity of the materials chosen to absorb the exudate.", "But in all cases current wood pulp fluff absorbent products will feel wet and/or cold to the skin the longer the product is worn.", "The current state of the art product design for the synthetic absorbent cores is based upon a synthetic continuous fiber matrix inter-layered with superabsorbent particles (SAP).", "For example a polypropylene tow fiber similar to tow used in cigarette filter making was chosen.", "This material is purchased in a continuous form and is pulled out of the box and proceeds into an air trumpet or similar device or the like, to expand the fiber tow matrix.", "Then SAP particles are intermixed, adhesive is sprayed into the fiber SAP matrix and the entire matrix is wrapped to result in what is the state of the art of current “Pulpless” core technology.", "This type of core has the major limitations of a slow absorbency rate.", "That rate is highly dependent upon the SAP chosen and on the adhesive type and amount required to attach the SAP to the tow fiber matrix.", "For example, if enough adhesive is provided to ensure that the SAP remains in its desired location within the core, that adhesive may limit the SAP's absorbent swelling due to coating part of the SAP particles.", "If less adhesive is utilized, while it may permit greater swelling and absorption of the exudate by the SAP, it may allow the SAP particles to fall from their positions in the core to the bottom of the crotch area, rendering it heavier and wetter in the crotch area when voided into and less absorbents at the ends.", "Another example of current pulpless core technology is gluing the SAP to the back sheet or inside the top or body facing sheet.", "This bonding process may limit the SAP from being fully expanded and utilized in absorbing the exudate.", "When bonded in such a matter, the SAP may be also be applied in continuous rows to provide space for the fluid to travel unhindered.", "Or the SAP may be intermixed with ground wood pulp fibers of similar size to enhanced fluid movement in this inefficient design.", "Current SAP limitations require having to choose between a higher absorbent capacity, with the disadvantage of having slower speed, or a faster SAP with less absorbing capacity.", "If the current SAPs are mixed, the fast acting SAP will very rapidly swell and may “gel-block” the slower acting, but higher absorption capacity SAP.", "If gel-blocking occurs, it will limit, or even prevent, the higher capacity SAP from desorbing the faster but lower capacity SAP.", "In the past a cellulose acetate fiber core with a single SAP has been developed and commercially available, as has a non-SAP version.", "Current polypropylene filament tow technology has also been used for the absorbent cores.", "In this regard, such polypropylene tow cores used in the market today make use of round or oval homo-polymer polypropylene fibers, which provide minimal resistance to fluid flow through the SAP/tow fiber matrix, thereby only providing minimal dwell time for the fluid to be absorbed by the SAP.", "While such prior art absorbable products containing wood fluff pulp are generally suitable for their intended purposes, they still leave much to be desired.", "In particular, the thickness of today's disposable absorbent products containing wood fluff pulp and the state of the art in pulp fiberizing technology result in an absorbent product that is significantly thicker than current cotton underwear.", "This results in a thicker product on the body which may not allow normal clothes or their usual size normal clothing to be worn.", "In addition the increased thickness of such products results in increased storage, transportation and handling costs and increased retail display space.", "In our aforementioned patent application there is disclosed and claimed a disposable absorbent garment, which overcomes many of the disadvantages of art absorbable products containing wood fluff pulp.", "In particular, that patent application discloses an exemplary absorbent assembly comprising a core formed of a synthetic tow or of synthetic nonwoven layers and having first section comprising a slow acting but high absorption capacity SAP and a second section comprising a fast acting but lower absorption capacity SAP, all of which is wrapped in a wrapper to hold the SAP in place.", "The absorbent assembly may be quilted and corrugated.", "The undergarment also includes releasably securable fasteners to enable it to be readily removed and a suspension system to ensure that the garment fits properly and doesn't leak even when holding a large amount of exudate.", "Odor removal/masking and treatment features may be provided.", "It addition the undergarment may include a wetness indicator.", "The subject invention is directed to an absorbent core assembly which constitutes an improvement over the absorbent cores of our aforementioned patent application.", "Thus the absorbent core assembly of this invention case be used in the absorbent garment of that patent application, or can be used in any other type of absorbent garment or in other absorbent product designed to quickly and efficiently absorb liquids without leakage therefrom.", "SUMMARY OF THE INVENTION In accordance with one aspect of this invention there is provided a method for making an absorbent core for use in a product used with a being for absorbing and retaining liquids from the body of the being.", "The method comprises forming a first section of at least one layer of a porous material configured to permit the migration of a liquid therethrough.", "The at least one layer of the first section is quilted by fixedly secured securement lines to form a plurality of first pockets, each of the first pockets being partially filled with

the migration of a liquid therethrough.", "The at least one layer of the second section is quilted by fixedly secured securement lines to form a plurality of second pockets, each of the second pockets being partially filled with a second volume of a fast acting but lower absorption capacity SAP therein.", "The second volume is different than the first volume.", "The first section is disposed over the second section so that they are in fluid communication with each other, whereupon the resulting core is configured such that a liquid contacting the first section flows through the at least one layer of the porous material of the first section into the first pockets and from there flows through the at least one layer of the second section into the second pockets to be absorbed quickly and rapidly by the fast acting SAP therein, while the slow acting SAP desorbs or takes liquid away from the fast acting SAP as well as absorbing the liquid itself.", "In accordance with one preferred aspect of the method of this invention the first volume of slow acting, but high absorption capacity SAP is free in the first pockets, and wherein the second volume of fast acting but lower absorption capacity SAP is free in the second pockets.", "In accordance with another preferred aspect of the method of this invention the at least one layer of the first section is formed of a nonwoven material and wherein the at least one layer of the second section is formed of a nonwoven material.", "In accordance with another preferred aspect of the method of this invention the first section includes two layers, each of the layers of the first section comprising a plurality of the first pockets containing a portion of the slow acting but high absorption capacity SAP therein.", "In accordance with another preferred aspect of the method of this invention the pockets are formed by ultrasonically bonding or thermally bonding or adhesively bonding.", "In accordance with another preferred aspect of the method of this invention the first pockets are offset with respect to the second pockets.", "In accordance with another preferred aspect of the method of this invention the method additionally

to form a protective disposable undergarment for the being.", "In accordance with another preferred aspect of the method of this invention the method additionally comprises providing a top sheet formed of a material enabling a fluid to pass therethrough, disposing the top sheet over the core, providing a bottom sheet comprising a layer formed of a barrier material to prevent a fluid voided by

accordance with another preferred aspect of the method of this invention the method additionally comprises providing the protective disposable undergarment with a wicking layer disposed between the first and second sections to enhance fluid transfer from between the first and second sections.", "In accordance with another preferred aspect of the method of this invention the wicking layer comprises an air-laid material.", "In accordance with another preferred aspect of the method of this invention the method additionally comprises providing the protective disposable undergarment with a fluid acquisition layer disposed over the first section, whereupon the fluid acquisition layer is interposed between the top sheet and the first section of the absorbent core.", "In accordance with another preferred aspect of the method of this invention the top sheet comprises a non-woven material.", "In accordance with another preferred aspect of the method of this invention the bottom sheet comprises a film barrier layer.", "DESCRIPTION OF THE DRAWING FIG.", "1 is a cross-sectional view of one exemplary embodiment of an absorbent core assembly constructed in accordance with this

figures of the drawing wherein like reference characters refer to like parts, there is shown in FIG.", "1 one exemplary embodiment of an absorbent core assembly 20 constructed in accordance with this invention.", "The core assembly 20 is designed to absorb liquids that in some way come out of or exit the body of a being, e.g., a person or animal, whether the being is living or dead.", "The liquid can be an exudate, urine, blood or any other fluid which includes a liquid as a component thereof.", "The core assembly of this invention has particular utility to be used as a component of a garment, e.g., protective disposable underwear, or a component of a bladder control pad, a sanitary napkin, a disposable diaper, etc.", "Moreover, it can be used as part of a protective pad for use on a bed or on other furniture or may be used as a part of a coffin liner.", "It may also be used as a wound dressing.", "In fact, the core assembly 20 of this invention need not be used to absorb liquids from a being, but can be used for other liquid absorbing purposes.", "For example, a core assembly constructed in accordance with this invention can be used to absorb aqueous chemical or other liquid spills.", "Turning now to FIGS.", "1 and 3, the absorbent core assembly 20 as shown therein basically comprises a generally planar body of any suitable peripheral shape.", "In this exemplary case the core assembly 20 is an elongate rectangle, having a longitudinal axis 22 and a transverse axis 24.The core assembly 20 is composed of at least two layers (to be described below) which are fixedly secured together along their longitudinally extending side edges 26 and their transversely extending end edges 28 by any suitable bonding technique, e.g., ultrasonic bonding, thermal bonding, adhesive bonding, etc.", "The first or top layer 30 of the core assembly 20 constitutes an acquisition layer, and is configured to be located confronting the being.", "This layer, while preferred, is optional such that it can be used for some applications and omitted for other applications.", "If used, the acquisition layer 30 serves to move the liquid to be absorbed linearly across its area to spread it out across the core assembly.", "In accordance with one exemplary embodiment of this invention the layer 30 is an airlaid material, such as Shalag STAPPEL40 ADL, STA1PBL40 or STA2PBL38m sold by Shalag US, Inc. or a similar material produced by WPT Corporation or other suppliers of similar ADL nonwoven materials.", "Such a material is identified by the vendor as being 40 gsm 100% Polyester White.", "Other similar airlaid acquisition layer materials incorporating Polypropylene, Polyethylene Bi-component fibers or the like used in the industry can be used, with a basis weight ideally of 40 grams per square meter (gsm) +/−10 gsm, although usage as low as 20 gsm or up to 100 gsm is infrequently used.", "Another alternative is to use a 3D film such as that available from Tredegar Film Products under the trademark AquiDry Plus 120.The second layer 32, which is sometimes referred to hereinafter as the “first section” of the core is best seen in FIGS.", "1 and 4.Thus, as can be seen it is of elongated rectangular shape and is preferably coextensive in size and shape to the first layer 30.Like the layer 30, the first section or layer 32 is also provided to move the liquid linearly.", "However, unlike the first layer 30, the first section or layer 32 is a required layer.", "It is constructed using high capacity, but slow absorbing SAP particles 38, encapsulated between two sheets or webs 32A and 32B as best seen in FIG.", "7.In accordance with one exemplary embodiment of this invention the sheets or webs are formed of a non-woven, liquid pervious material, e.g., 15 +/−5 grams per square meter basis weight hydrophilic spunbond nonwoven polypropylene or the like.", "One particularly suitable nonwoven is available from PGI Nonwovens under code # B0305 white SBPP hydrophilic polypropylene spunbond.", "At minimum the upper body side layer 32A is hydrophilic where the bottom layer 32B, may be similar for ease of manufacturing.", "Alternatively, it could be hydrophobic or an apertured film.", "Like the top layer 30, the layer 32 is also of elongated rectangular shape and preferably is coextensive is size and shape with the top layer 30.The formation of the first section or layer 32 of the core assembly 20 is achieved by fixedly securing the webs or sheets 32A and 32B to each other by intersecting seal lines 40 to thereby result in a quilted subassembly having a plurality of compartments or pockets 42 located between the intersecting seal lines.", "The quilted nature of the first section 32 renders the SAP 38 particles of that section resistant to migration with respect to the core assembly and thus obviates the need for adhesives to bond to the SAP particles to prevent their migration.", "The seal lines 40 can be made by any suitable technique, e.g., ultrasonic welding, thermal welding, adhesive securement, etc.", "One exemplary embodiment of the first section 32 constitutes a diamond-like pattern of the intersecting lines 40 wherein each pocket 42 is of a square shape and is approximately 1.5 cm by 1.5 cm.", "with the width of each of the intersecting seal lines 40 being approximately 1 mm.", "Each pocket 40 of the first section contains free high capacity, but slow absorbing SAP, with each pocket being filled to less than half of its capacity, and preferably within the range of approximately one third to one quarter (or even slightly less) of its capacity.", "In accordance with one exemplary embodiment of this invention the high capacity, but slow absorbing SAP 38 can be Aqua Keep type SA605, SA60SX11 or Aqua Keep type SA55SX11 available from Sumitomo Seika Chemicals Co., Ltd., or can be BASF T-9400, BASF T-9600 or BASF T-9900 available from BASF Corporation, or any other suitable SAP.", "Preferably the SAP 38 should have a vortex time of at least, e.g., approximately 40 to 60 or more seconds.", "As is known in the art the term “vortex time” represent the amount of time that it takes SAP which is mixed with water in a vessel by a spinning stirrer to form a gel to stop the spinning stirrer.", "Each pocket 40 encapsulates approximately 0.07 to 0.08 grams of SAP, or approximately 100 grams of SAP per square meter.", "The partial filling of the pockets with the high capacity, but slow absorbing SAP 38 serves to allow for the expansion and swelling of the SAP when in contact with the liquid to be absorbed, e.g., urine.", "If the pockets 40 were filled with significantly more SAP 38, such as greater than 0.32 grams per pocket, the SAP 38 would be constrained in its ability to swell and thus unable to absorb additional fluid.", "In some instances it may be appropriate to underfill the pockets employing 0.04 grams or even 0.02 grams to ensure maximum utilization at a slightly reduced capacity.", "It should be pointed out that other size pockets than those described above are contemplated.", "For example, one can increase the amount of SAP 38 per pocket 40 by employing larger pockets.", "In each case, the ratio of SAP 38 to the pocket size should not exceed approximately 0.4 grams per 4 square centimeters per pocket.", "If larger pockets are contemplated, then the same ratio of weight per unit area should be applied.", "The third layer 34 of the core assembly 20 is also optional, but desirable, and is shown best in FIGS.", "1 and 5.This layer serves to aid in transporting liquid by wicking or the like.", "In particular the layer 34 is configured to aid in allowing the liquid to linearly wick so that it assists in moving the liquid to be absorbed, e.g., urine, from the central middle area of the core where the liquid is first insulted to the ends of the core where that liquid may not fully reach and to allow that liquid to pass through it into the fourth or bottom layer.", "In the exemplary embodiment, the wicking layer is a fluid wettable hydrophilic layer containing absorbent tissue, cotton or the like ranging from approximately 50 to 200 gsm.", "One particularly suitable material for the wicking layer 34 is available from Domtar/EAM Corporation under the trademark Nova Thin and is described as White Fibrous Web of 100 gm basis weight.", "The layer 34 has a corduroy or corrugated embossing pattern that is employed to further assist wicking.", "The corrugations or corduroy pattern is formed by a plurality of closely disposed parallel seal lines 44 made by any suitable technique, e.g., ultrasonic welding, thermal welding, adhesive securement, etc.", "The wicking layer is also of elongated rectangular shape, but preferably of a smaller size than the layers 30 and 32 and is not bonded (for a reason to be described later).", "Moreover, the wicking layer 34 may be in the form of plural layers to provide the desired wicking properties.", "The wicking layer may also have visible holes, of 1 mm in size or larger, added to further enhance fluid pass through.", "The fourth or bottom layer 36 is also a required layer and is sometimes referred to hereinafter 36 is preferably coextensive in size and shape to the first section 32.The second section 36 is configured to be disposed away from the being and is constructed somewhat similarly to the first section 32.To that end, the second section is in the form of fast acting but lower absorption capacity SAP particles 46 encapsulated between two sheets or webs 36A and 36B of a non-woven, liquid pervious material, e.g., 15 +/−5 gsm basis weight polypropylene like that used in the first section 32.Like the webs or sheets of the first section, the webs or sheets 36A and 36B of the second section are fixedly secured to each other by intersecting seal lines 48 to form a quilted subassembly having a plurality of compartments or pockets 50 located between the intersecting seal lines.", "The seal lines are formed by any suitable technique, e.g., ultrasonic welding, thermal welding, adhesive securement, etc.", "Each pocket 50 contains a portion of the fast acting but lower absorption capacity SAP 46 therein, with each pocket being filled to less than half of its capacity, and preferably within the range of approximately one third to one quarter (or even slightly less) of its capacity.", "In accordance with one exemplary embodiment of this invention the fast acting but lower absorption capacity SAP 46 can be Aqua Keep type SA10 or Aqua Keep type BA40B available from Sumitomo Seika Chemicals Co., Ltd., or the like.", "Those products have a very fast vortex time, e.g., approximately 4 to 10 seconds.", "It is preferred that the SAP 46 of the second section have a vortex time of less than 10 seconds, but longer times may be suitable, depending upon the application.", "In any case, like the first section, the quilting of the second section renders the SAP 46 of the second section resistant to migration with respect to the core assembly without requiring adhesives to bond to the superabsorbent particles to prevent their movement or migration.", "The sheets or webs 36A and 36B of the second section 36 are ultrasonically bonded in a diamond pattern pocketing like the first section, with each pocket 50 being approximately 1.5 cm by 1.5 cm square and with the width of the intersecting seal lines being approximately 1 mm in width.", "Other thermal techniques may also be employed.", "Each pocket 50 encapsulates approximately 0.02 to 0.08 gm of the SAP 46, or approximately 100 gsm per square meter.", "In this construction adhesives to bond to the superabsorbent particles to prevent their movement or migration are not required, nor desired.", "The pockets 50 are only partially filled to allow for the expansion and swelling of the superabsorbent polymers when in contact with the fluid.", "If the pockets were filled with significantly more superabsorbent polymer particles 46, such as greater than 0.32 gm per pocket, the SAP particles would be constrained in their ability to swell and thus unable to absorb additional fluid.", "However, other size pockets may be contemplated to increase the amount of SAP per pocket by employing larger pockets.", "In each case, the ratio of SAP 46 to the pocket size should not exceed approximately 0.4 gm per 2.25 square cm per pocket.", "If larger pockets are contemplated, then the same ratio of weight per unit area should be applied.", "As best seen in FIGS.", "1 and 3, the four layers 30, 32, 34 and 36 are fixedly secured together along their marginal edges by respective seal lines 52 to form a composite assembly.", "The seal lines 52 are formed by any suitable technique, e.g., ultrasonic welding, thermal welding, adhesive securement, etc.", "The most desirable process is to ultrasonically bond the four layers together with a two mm wide intermittent bond pattern running down the sides of the four layer composite core and spaced about one cm from each edge, e.g., somewhat like a railroad track with approximately four bond points or bars per cm.", "To assist in bonding the wicking layer 28 is narrower than the total composite core.", "For example if the composite core is 100 mm wide, the non-thermal bondable wicking layer will be no wider than 75 to 80 mm in width.", "This is done to assist ultrasonically bonding the three fusible layers 30, 32 and 36, encapsulating the non-fusible layer 34 between them.", "An alternative construction would be to use an adhesive either lightly sprayed or slot coated to allow the fluid to travel through the construct unhindered.", "The absorbent core assembly 20 is arranged to be located in a garment, to be described shortly, such that the layer 32 (the first section of the core) constitutes a body-facing side confronting the being and the layer 36 (the second section of the core) constitutes a remote-facing side disposed away from the being, whereupon a liquid voided, exuded or otherwise emanating from the body of the being flows through the first section to the fast acting SAP in the second section to be absorbed quickly and rapidly by the fast acting SAP therein, while the slow acting SAP desorbs or takes liquid away from the fast acting SAP as well as absorbing the liquid itself.", "The wicking layer 30 serves to enhance the fluid transfer from the lower faster absorbent layer 36 into the upper slower absorbent layer 32.In order to improve fluid movement through the entire composite absorbent core, it is preferred that the embossed pockets 42 and 50 are not aligned directly with respect to each other.", "Rather they are offset in the X direction (parallel to the longitudinal axis 22) and/or in the Y direction (parallel to the transverse axis 24).", "This allows for improved fluid migration not only in the X/Y direction, but also in the Z direction, i.e., perpendicular to the plane of the core assembly.", "However, if desired, e.g., in the interest of ease and simplicity of manufacturing the core, reduced capital costs and concomitant consumer savings, the embossed pockets may be directly aligned under each layer and under each other.", "As should be appreciated by those skilled in the art the quilted construct of a core assembly 20 constructed in accordance with this invention functions via what can be called a “compartment spill over phenomena”.", "In particular, the liquid to be absorbed when brought to the each section of the core will fill up the SAP contained in a compartment (pocket) of that section, whereupon the compartment and the SAP in it will swell.", "Once the SAP in that compartment is fully utilized (e.g., has swelled to its maximum), the liquid then “spills over” to the adjacent compartments.", "As mentioned above, the ultrasonically formed SAP diamond shaped compartments 44 and 50 of the first section 32 and the second section 36, respectively, have approximately a 1 mm space between them as a result of the width of their respective intersecting seal lines 40 and 48.This aids in liquid movement, along the voids 54 in the core assembly adjacent those seal lines as shown in the cross-sectional view of FIG.", "1.As will be appreciated by those skilled in the art, the wicking layer 34 also enhances liquid movement and does the unaligned nature of the compartments or pockets.", "The addition of a topmost body side layer, commonly referred as an acquisition layer, transfer layer or distancing layer further aids fluid transfer to assist fluid in the spill over from one SAP containing compartment or pocket to the next.", "It should be pointed out at this juncture that if a higher capacity absorbent core is desired, one or more additional SAP layers like those of the first section and/or the second section could be added to the construct.", "In addition, a second wicking layer could be added between the SAP absorbent layers, if desired.", "Turning now to FIG.", "9, there is shown a more preferred core assembly 120 constructed in accordance with this invention.", "The core assembly 120 is of similar construction to the core 20, except that the first section of the core assembly 120 is made up of two layers and instead of a single layer 32.In the interest of brevity the components of the core assembly 120 which are common with the core assembly 20 will be given the same reference numbers and the details of their construction, assembly and operation will not be reiterated.", "Thus, as can be seen the core assembly 120 includes an optional top layer 30, a first section 132 made up of two layers 32, a wicking layer 34 and a second section 36.Each of the two layers 32 making up the first section 132 is constructed in a similar manner to the layer 32 of the core assembly 20.In particular, each layer 32 is constructed using high capacity, but slow absorbing SAP particles 38, encapsulated between two sheets or webs 32A and 32B as best seen in FIG.", "7.Each sheets or web are formed of a non-woven, liquid pervious material, e.g., 15 +/−5 grams per square meter basis weight hydrophilic spunbond nonwoven polypropylene or the like, such as that available from PGI Nonwovens under code # B0305 white SBPP hydrophilic polypropylene spunbond.", "The formation each layer 32 of the first section 132 of the core assembly 120 is achieved by fixedly securing the webs or sheets 32A and 32B to each other by intersecting seal lines 40 to thereby result in a quilted subassembly layer having a plurality of compartments or pockets 42 located between the intersecting seal lines.", "The two layers 32 of the first section 132 are superimposed over each other such that their pockets 42 are not aligned longitudinally or transversely.", "By making use of two layers of the first section, the core assembly 120 can use less SAP in each of the pockets 42 of the first section than is used in the pockets 42 of the first section of the core assembly 20.For example, the amount of SAP 38 in each of the pockets 42 of the two layers may be in the range of one third to one quarter or less than the capacity of the pocket.", "This configuration provides sufficient room for the SAP 38 to expand in the pockets 42 so that it can be fully utilized to desorb the SAP 46 from the second section 36.While it is desirable to use the least amount of SAP 46 in the pockets 42 of the first section for economic reasons, the amount used must be able to be fully utilized to achieve the desired absorption rate and capacity.", "Thus, is preferred that the SAP 42 in each of the two layers of the first section 132 is within the aforementioned desired range of pocket fullness and that the SAP has a vortex time of at least 60 seconds to be able to fully desorb the liquid from the second section 32.Moreover, that configuration maximizes SAP performance and enables efficient and effective transfer of liquid introduced into the core assembly through each of the two layers of the first section into the second section, without any tendency for the SAP 38 of the first section to impede the flow of liquid into the second section 32 as could result from “gel blocking”.", "As is known “gel blocking: occurs when the surface of the SAP in a section that comes into contact with the liquid first swells and blocks the lower levels of SAP of that section from fully absorbing to their maximum capacity.", "Thus, by using less SAP in each pocket 42, but by using more pockets via the two layer construction of the first section 132, the occurrence of gel blocking is minimized if not eliminated.", "Thus, the liquid introduced into the core assembly can quickly pass through the first section to be wicked into the second section, where it is quickly absorbed by the SAP of the second section, and from whence that liquid can go back to the first section where that liquid is slowly absorbed, thereby desorbing the second section, so that all of the liquid is trapped in the core assembly to keep the user of the core dry.", "While the preferred embodiment of the core 120 includes two layers in the first section 132, that is merely exemplary.", "Thus, it is contemplated to use more than two layers in that section, with the pocket sizes and capacity being adjusted accordingly.", "However it should be recognized that there is an additional cost in using more than two layers for the first section, e.g., the cost of the non-woven material encapsulating the additional layer(s).", "Moreover, if desired the second section 36 may be made up of multiple quilted layers.", "Further still, it is also contemplated that the subject invention can use less expensive inorganic additives to maximize SAP performance.", "Since the goal of the core of this invention is to allow all the SAP particles of each section to achieve their maximum absorbent capacity, inorganic additives such as high porosity Zeolite's, Upsalite, microspheres or other inorganic materials that do not swell or add to the gel blocking phenomena may be included with the SAP of the core.", "Another approach in lieu of the use of such inorganic additives, or an additional approach to using such additives, is to utilize an acquisition layer, such as a 40 gm Shalag ADL or similar materials from Shalag US, Inc. or similar materials available from WPT Corporation or others may be disposed underneath the second section of the core.", "Absorbent cores constructed in accordance with this invention, such as those described above or variations thereof, could be used in lieu of an absorbent core that is employed in current existing absorbent products.", "For example, core assemblies constructed in accordance with this invention can be used in adult incontinence products (e.g., briefs, panties, pads, etc.", "), infant absorbent garments (e.g., diapers), sanitary napkins, a feminine napkins, panty liners, or any other product arranged to be worn by a being to absorb liquids from the being.", "In FIG.", "2 there is shown a cross-sectional view of the crotch region of an exemplary product, e.g., an adult incontinent brief, 10 making use of a core assembly 20.The brief 10 includes a top sheet 10A and a bottom sheet 10B.", "The top sheet may be a non-woven material like that typically used in products of this kind.", "The bottom sheet 10B constitutes a barrier layer, e.g., constitutes a film of polyethylene or polypropylene, also like that typically used in products of this kind to insure that none of the liquid leaks out the brief.", "Located between the top and bottom sheets 10A and 10B, respectively, is the core assembly 20.In FIG.", "10 there is shown a cross-sectional view of the crotch region of another exemplary product, e.g., also an adult incontinent brief 12, making use of a core assembly of this invention, in this case core assembly 120.The brief 12 is of similar construction to the brief 10, except for the use of the core assembly 120 in lieu of the core assembly 20.In the interest of brevity the components of the brief 12 that are common with the brief 10 will be given the same reference numbers and the details of their construction, assembly and operation will not be reiterated.", "Thus, it can be seen that the brief 12 includes a top sheet 10A and a bottom sheet 10B.", "The top sheet may be a non-woven material and the bottom sheet 10B may be a barrier film of polyethylene or polypropylene, like that typically used in products of this kind.", "Located between the top and bottom sheets 10A and 10B, respectively, is the core assembly 120.Other alternative constructs for absorbent core assemblies of this invention are also contemplated.", "For example, in order to create the maximum absorbent capacity in a product with improved surface dryness, such as the adult incontinent briefs described above, one can apply one or more layers of a quilted SAP containing nonwoven layer over the top of an airlaid or fluff mat, but under the top sheet of the brief.", "The SAP needs to absorb slower than the pulp containing-mat underneath it to act as a surface dryness reservoir.", "In this construct, the SAP layer may be smaller than the airlaid or fluff mat.", "In order to increase speed of absorbency and total capacity of the pad of that garment, one or more layers of a quilted SAP containing nonwoven layer under the bottom of an airlaid or fluff mat, but above the polyethylene or polypropylene barrier film.", "The SAP needs to absorb faster, or at least as fast, as the pulp containing mat above it to act as a fluid containment layer.", "Garments or other absorbent products making use of a quilted SAP containing nonwoven layer over the top of an airlaid or fluff mat, but under the top sheet as described above, may be of similar size, smaller and may be shaped other than being of a rectangular shape like the core assemblies described above.", "Similarly, absorbent core assemblies may make use of one or more quilted SAP layers under airlaid or fluff mat, but above the polyethylene or polypropylene barrier film as described above, may be provided and may be of similar size, smaller or even shaped other than being of a rectangular shape.", "As mentioned above, the subject invention also contemplates use of the absorbent core assembly in pad for disposition on a bed or other article of furniture to protect the bed or other article from liquids, e.g., urine, or may be in the form of a coffin liner to protect a coffin from liquids exiting the body of a corpse disposed thereon.", "For either of such applications, the pad/liner may be in the form of a unitary composite composed of four layers.", "The first layer constitutes the top sheet of the pad and is configured to be in contact with the being's body and may be composed of a polypropylene spunbond or the like, usually 15 gsm +/−5 gsm.", "Alternatively, it may be of a higher basis weight or a synthetic through-air bonded carded web.", "The next layer may be a single layer or multiple layers and forms the first section of the pad/liner.", "The first section is in the form of a high capacity but slow absorbing layer of SAP particles encapsulated between two layers of 15 +/−5 grams per square meter polypropylene or the like material in a quilted pocketed configuration.", "The pockets contain free SAP and are filled at less than 20%, and preferably in the range of approximately 1% to 5%.", "This layer serves to allow fluid to pass therethrough.", "The third layer constitutes the second section of the pad is also required.", "It may be a single layer or multiple layers.", "In any case it contains a fast absorbing SAP with a vortex time of no more than about 10 seconds.", "This fast absorbing layer of SAP is encapsulated between two layers of 15 +/−5 grams per square meter polypropylene or the like material in a quilted pocketed style.", "The pockets contain free SAP and are filled at less than 20% and preferably in the range of approximately 1% to 5%.", "The construction of this layer enables it to rapidly capture the fluid and pull it away from the being's body.", "Then the layers of SAP above this layer may desorb this layer due to their higher capacity.", "The fourth layer is a barrier layer composed of a barrier film or film laminate and serves to prevent leakage onto the bedding or other furniture on which the pad/liner is disposed.", "The four layers of the pad/liner are preferably sealed around the entire perimeter of the pad/liner by ultrasonic bonding, thermal bonding or by adhesives in a continuous or intermittent pattern or the like.", "It also may have the layers or parts therein bonded to each other with adhesives or in spots using known techniques such as ultrasonic bonding, thermal bonding, etc.", "Instead of using the above composite as a unitary pad structure, it may also be used in place of airlaid or pulp fluff mats used in the current under-pads to retrofit such under-pads.", "To that end a composite structure in accordance with this invention can be provided.", "That structure includes only the second and third layers as discussed above which would be used as an insert into current processes in place of their current airlaid or SAP/airlaid materials or pulp or pulp/SAP mats.", "Further a single pocketed layer of the SAP like that used in the subject invention can be used either alone or in conjunction with airlaid or pulp/SAP mats as follows.", "A single high capacity SAP pocked layer may be added on top of a current absorbent core for added capacity.", "This structure would also provide the advantage of increased dryness and total capacity.", "A single fast absorbing SAP pocked layer may be added under the current absorbent core to increase the speed of the management of fluid.", "Such a structure would also increase the speed of absorbency and total capacity.", "All of the foregoing under-pads can be readily produced as a continuous roll of absorbent pads on a roll that could be more easily used like paper towels on a roll.", "To that end, each under-pad can be manufactured so that it is attached to the corresponding next under-pad through a series of weak perforations or the like.", "As should be appreciated from the foregoing the cores of this invention as described above make use of at least two sections, each of which is of a quilted construction including plural pockets.", "Moreover, each of the pockets is hollow and is partially filled with SAP.", "The SAP may be in the form of particles or fibers or any other form of SAP which is free or unsecured.", "The pockets serve to hold the SAP therein to prevent migration of the SAP through the core.", "It is, however, contemplated that for some applications an adhesive could be used in the pockets to thereby hold the SAP in place.", "That alternative configuration provides an additional means, in addition to the pockets, for preventing the SAP from migrating through the core.", "Without further elaboration the foregoing will so fully illustrate our invention that others may, by applying current or future knowledge, adopt the same for use under various conditions of service." ] ]

upon entering the store of merchant 119.In several embodiments, consumer 129 can decide whether to authorize the transaction using mobile device 120.For example, mobile device 120 can ask consumer 129 to approve the transaction in mobile application 123.In a number of embodiments, mobile application 123 can present the one or more of consumer accounts 131 to consumer 129 to select which of the consumer accounts 131 to use to funds the transaction.", "In some embodiments, consumer 129 can choose to split the funding of the transaction among multiple accounts.", "For example, consumer 129 can choose to fund 20% of the transaction from a demand deposit account (e.g., a debit account) and 80% of the transaction from a non-demand deposit account (e.g., by a charge to a credit account).", "In some embodiments, if an account of the one or more of consumer accounts 131 has an account balance that is less than the amount of the transaction (or the portion of the transaction that consumer 129 has chosen to allocate to the account), loan module 126 of mobile device 120 can determine that there is a deficiency and can present an option to fund the transaction (or a portion of the transaction) using a non-demand deposit account, such as a loan account, a credit account, or a points account.", "In other embodiments, loan module 126 can present the option for funding the transaction through a non-demand deposit account even if there is no deficiency in the one or more of consumer accounts 129.In some embodiments, the loan account can be a new account that is created upon consumer 129 choosing to fund the transaction (or portion thereof) with the loan account.", "In other embodiments, the loan account can be for a previously authorized loan.", "In some embodiments, the loan account can have a pre-existing loan balance, which can be increased based on the amount of loan used to the fund the transaction.", "In several embodiments, the loan can be a small loan, and can be labeled a “micro-loan”), but can be treated the same as credit line for a loan instead of an overdraw of an account.", "In several embodiments, consumer 129 can make the decision from which account or accounts to fund the transaction, and/or to authorize a loan or a credit transaction, while at or near the point-of-sale terminal 110 in the store of merchant 119.In the same or other embodiments, loan module 126 can allow consumer 129 to choose the one or more accounts from which to fund the transaction after consumer 129 has left the store.", "In many embodiments, financial institution 130 can fund the transaction temporarily from a shadow account that the bank uses to fund overdraft transaction, which can be reimbursed from the one or more accounts selected by consumer 129.For example, consumer 129 can authorize a transaction at point-of-sale terminal 110 in the store, and financial institution 130 can authorize transfer of funds to financial institution 150 to pay merchant 119, and after consumer 129 leaves the store of merchant 129, loan module 126 can push a message to consumer 129 asking for one or more of consumer accounts 131 that consumer 129 wants to use to fund the transaction.", "The options of consumer accounts 131 can include the option to open a new loan account, or to add to the balance of an existing loan account.", "In some embodiments, consumer 129 can setup a list (e.g., prioritized list) of consumer accounts 131 to use for transaction using mobile device 120, and/or can setup before-hand an amount and/or percentage to use from one or more of the accounts.", "For example, consumer 129 can choose to use a debit account for the first $50 and then use a credit account for the rest.", "As another example, consumer 129 can choose to use a debit account for 40% of the transaction, and use a new micro-loan for the rest.", "In some embodiments, a points account can be used to pay for all or at least a portion of the payment.", "For example, consumer 129 can have a points account at financial institution 130, which can have a balance of points earned by consumer 129 at financial institution 130.In many embodiments, these points can have an exchange value, such that the points can be redeemed to pay for all or at least a portion of the payment.", "In many embodiments, after mobile device 120 has communicated with point-of-sale terminal 110 using communication module 124 to receive the merchant identifier and other transaction information, and consumer 129 has authorized the transaction, mobile device 120 can communicate with financial institution 130 and/or transaction system 140, either directly or through mobile wallet provider 160, to request a payment be made to merchant account 151 of merchant 119 from one or more of consumer accounts 131.For example, when mobile device 120 communicates with financial institution 130 (either directly or through mobile wallet provider 160) to request a payment be made, account module 134 of financial institution 130 can determine account information about merchant account 151, such as the account identifier of merchant account 151, at least partially based on the merchant identifier received from mobile device 130.In some embodiments, financial institution 130 can communicate with transaction system 140 to get the account information about merchant account 151, which can be stored in merchant account database 141.In some embodiments, financial institution 130 can save the account information about merchant account 151 so financial institution does not need to query the account information from merchant account database 141 in transaction system 140 for future transaction involving the same merchant identifier.", "In other embodiments, financial institution 130 can query for the account information from merchant account database 141 in transaction system 140 for each new transaction, or at occasional and/or regular intervals.", "In other embodiments, when mobile device 120 communicates with transaction system 140 (either directly or through mobile wallet provider 160) to request a payment be made, transaction system 140 can provide the account information about merchant account 151 to first financial institution 130.In many embodiments, having the account information about merchant account 151, financial institution 130 can initiate a payment to financial institution 150 from one or more of consumer accounts 131 to merchant account 151.In several embodiments, before initiating payment, authorization module 133 can determine whether to authorize payment from one or more of consumer accounts 131.For example, financial institution 130 can determine whether the payment amount is within the available funds in one or more of consumer accounts 131, determine whether one or more of consumer accounts 131 is currently open and in good status (or closed), authenticate the identity of consumer 129 using mobile device 120, and/or perform other actions.", "For example, in some embodiments, authentication module 121 can authenticate the identity of consumer 129, and that information can be communicated from mobile device 120 to financial institution 130.In some embodiments, mobile device 120 can prompt consumer 129 to authenticate before and/or after mobile device 120 receives the merchant identifier and/or the transaction information from point-of-sale terminal 110.In some embodiments, authorization module 133 can request additional authentication from authentication module 121 (which can be directly through a network between financial institution 130 and mobile wallet 120, or can be through mobile wallet provider 160 and/or through transaction system 140) after receiving the request for payment from mobile device 120 and/or after receiving the information about merchant 119 and/or merchant account 151.In a number of embodiments, authorization module 133 of financial institution 130 can perform different and/or varying levels of authentication based on various factors.", "For example, authentication module 121 and/or authorization module 133 can determine whether mobile device 120 used to send the request for payment has been previously used by consumer 129 for transaction with financial institution 130, whether biometrics of the consumer match stored biometrics of consumer 129, whether the requested transaction and associated details (e.g., the identity of merchant 119, the location of merchant 119, the payment amount, the one or more items to be purchased (e.g., a list of SKUs), and/or other suitable factors) are consistent with spending patterns of consumer 129, whether consumer 129 has reported mobile device 120 lost or stolen, whether consumer 129 has reported that credit cards, debit cards, or other information about one or more of consumer accounts 131 have been lost or stolen, and/or other suitable factors.", "In various embodiments, financial institution 130 can adjust the level of authentication used to verify the identity of consumer 129 based on one or more of these factors, and/or based on the payment amount, the identity of merchant 119, the location of merchant 119, historical spending of consumer 129, and/or other relevant information.", "In some embodiments, if one or more of consumer accounts 131 chosen by consumer 129 for the transaction is short on funds or otherwise cannot be fully used, loan module 135 can communicate with loan module 126 to present other funding options to consumer 129, such as the option for a micro-loan to fund all or part of the transaction, as described above.", "In many embodiments, after receiving authorization from authorization module 133, financial institution 130 can initiate a payment to financial institution 150 to transfer funds from one or more of consumer accounts 131 to merchant account 151.In a number of embodiments, the payment can be effected by sending payment information regarding a payment to be made to merchant account 151 from one or more of consumer accounts 131.In a number of embodiments, the payment information transferred from financial institution 130 to financial institution 150 can effectuate an authenticated credit push, which can irrevocably satisfy payment to the merchant and/or ensure that the merchant has good funds when consumer 129 leaves the store of merchant 119.For example, the payment can be a settlement credit push of funds for the payment amount from one or more of consumer accounts 131 to merchant account 151, which can be settled immediately.", "In various embodiments, the payment information transferred from financial institution 130 to financial institution 150 can effectuate a push promise to pay, which can provide an irrevocable guarantee of payment from financial institution 130 to financial institution 150.In several embodiments, for example, the payment can be an ACH (Automated Clearing House) credit push, which can provide an irrevocable funding guarantee.", "In many embodiments, the payment and/or the guarantee of payment can be sent in real-time from financial institution 130 to financial institution 150, which can happen for each such transaction.", "In some embodiments, the settlement of the transaction can happen later, such as in a nightly batch fashion, and in some embodiments, can happen through a different network, such as an ACH network or a credit network.", "In other embodiments, the real-time payment and/or guarantee of payment can be processed through an ACH network or a credit network.", "In some embodiments, the consumer can provide instructions to financial institution 130 to label the transaction as a debit or a credit transaction in one or more of consumer accounts 131, and in some embodiments can provide such instructions with the request to pay, or before or after the request to pay.", "In some embodiments, a credit transaction can be treated as a micro-loan, as described above.", "In certain embodiments, a debit pull with guaranteed promise to pay can be used, such that financial institution 150 can receive a guaranteed promise to pay from financial institution 130 and pull the funds using a debit pull.", "In various embodiments, transaction system 140 can store information regarding each transaction in transaction database 142.In several embodiments, transaction system 140 can serve as a central auditor for transactions between the financial institutions (e.g., 130, 150) in data communication with transaction system 142.In some embodiments, transaction system 140 can receive some or all of the information from the merchant security transaction code.", "In various embodiments, one or more portions of the merchant security transaction code can be encrypted by security module 115.For example, the merchant security transaction code can include an encrypted portion that can be decrypted by security module 146 of transaction system 140, which can be used to ensure that the message has not been tampered.", "In other embodiments, the merchant security transaction code is not encrypted, but is digitally signed, as described above, and the digital signature can be verified, in some embodiments, by security module 146, which can advantageously ensure that the merchant identifier correctly identifies merchant 119, so that the funds are paid to merchant account 151 corresponding to merchant 119.In a number of embodiments, financial institution 150, upon receiving payment and/or guarantee of payment, can notify point-of-sale terminal 110 and/or merchant 119 in real-time that merchant 119 has satisfactorily received payment from consumer 129.For example, the notification can include various information, such as the transaction identifier, the amount received in payment (or guarantee), the merchant identifier, and/or other information.", "Receiving the notice of good funds can allow merchant 119 to proceed, such as, for example, to allow consumer to leave the store of merchant 119 with the items.", "In some embodiments, for example, point-of-sale terminal 110 can match the notification to the pending transaction in point-of-sale terminal 110 using the transaction identifier.", "In certain embodiments, merchant 119 can match the notification to the point-of-sale terminal using the merchant identifier.", "In some embodiments, consumer 129 can receive a notification on mobile device 120 that the transaction has cleared, such as shown in FIG.", "22 and described below.", "In several embodiments, system 100 can advantageously provide a number of technological improvements that can overcome technological problems in conventional systems.", "For example, in several embodiments, system 100 can beneficially allow consumer 129 to send payment directly and/or immediately to merchant 119 when consumer 129 is checking out at point-of-sale terminal 110.In many embodiments, the payment systems and methods provided by system 100 described herein can eliminate the acquirer model that is conventionally used in payment card transactions.", "In several embodiments, the payment systems and methods provided by system 100 described herein can advantageously streamline payments by eliminating the need for the financial institution (i.e., the acquirer) of merchant 119 to request payment from the financial institution (i.e., the issuer) of consumer 129.For example, in many embodiments, financial institution 150 does not need to request payment from financial institution 130.In many embodiments, the payment systems and methods provided by system 100 described herein can beneficially ensure merchants (e.g., merchant 119) are paid by consumers (e.g., consumer 129) while eliminating and/or reducing many of the transaction fees paid to various entities in the conventional model.", "In a number of embodiments, the payment systems and methods provided by system 100 described herein can advantageously eliminate the chargeback liability of merchants for fraudulent transactions.", "In the conventional acquirer-issuer model, the merchant (e.g., 119) is responsible for verifying the credit or debit card to ensure that the card is not being used fraudulently.", "In several embodiments, the payment systems and methods provided by system 100 described herein can beneficially place the liability on the financial institution (e.g., 130) of the consumer (e.g.", "129), which can be in a better position (e.g., with more and/or better information) than the merchant (e.g., 119) to determine if the request to pay is a legitimate, authentic transaction requested by the consumer (e.g., 129) and/or if the consumer's account is still open and in good status (or closed), has sufficient funds, etc.", "In various embodiments, the payment systems and methods provided by system 100 described herein can advantageously allow the financial institution (e.g., 130) of the consumer (e.g., 129) to choose how to authenticate the consumer (e.g., 129), and/or can beneficially allow the financial institution (e.g., 130) of the consumer (e.g., 129) to choose the level of authentication, which can be tailored for each consumer (e.g., 129) and/or for each transaction (e.g., the financial institution (e.g., 130) can decide, at least partially based on its risk determination, that a transaction with a higher payment amount warrants a higher level of authentication).", "In several embodiments, the liability for fraudulent use of one or more of the consumer accounts (e.g., 131) can be placed on the consumer (e.g., 129), and/or the consumer (e.g., 129) can choose the level of authentication used by the financial institution (e.g., 130) of the consumer (e.g., 129).", "In many embodiments, unauthorized access to one or more of consumer accounts 131 can beneficially be reduced and/or eliminated using the payment method provided by system 100 and described herein.", "In several embodiments, the payment systems and methods provided by system 100 described herein can beneficially provide the ability for financial institution 130 to communicate directly with consumer 129 at point-of-sale 110 when making a transaction.", "In many embodiments, the payment systems and methods provided by system 100 described herein can provide information to consumer 129, such as account balance, insufficient funds, lock/freeze on one or more of consumer accounts 131, etc., in real-time before consumer 129 requests payments, which can advantageously eliminate and/or reduce negative experiences of consumer 129, such as attempting to transact with insufficient funds or a freeze on one or more of consumer accounts 131.In a number of embodiments, the payment systems and methods provided by system 100 described herein can beneficially provide consumer 129 with the ability the ability to split the payment with one or more other accounts or a new loan, such as a micro-loan, which can allow consumer 129 to successfully make the payment and reduce negative experiences of consumer 129.In some embodiments, account information about one or more of consumer accounts 131 can beneficially be better protected from theft by the payment systems and methods provided by system 100 described herein, because, in a number of embodiments, the account information of one or more of consumer accounts 131 and/or personally identifiable information of consumer 129 can be undisclosed to third parties other than financial institution 130, which maintains consumer accounts 131.For example, in some embodiments, the account information of consumer accounts 131 and/or personally identifiable information of consumer 129 can be undisclosed to point-of-sale terminal 110, merchant 119, transaction system 140, and/or financial institution 150.In many embodiments, the account identifier (e.g., account number) of consumer accounts 131 is not sent across any networks, but resides solely in financial institution 130, which can beneficially prevent that information from being stolen.", "For example, the many recent large-scale data breaches of merchant systems that have exposed consumer account information and personally identifiable information of millions of consumers could have been mitigated by using the payment systems and methods provided by system 100 and described herein.", "In other embodiments, consumer 129 can choose to provide account information of one or more of consumer accounts 131 and/or personally identifiable information of consumer 129 to one or more third parties.", "For example, in some embodiments consumer 129 can set privacy instructions in mobile device 120 and/or with financial institution 130 regarding what information can be disclosed to third parties.", "For example, consumer 129 can elect to disclose certain information to merchant 119 in order to receive discounts, point, and/or other perks from merchant 119.For example, in some embodiments, financial institution 130 can send certain personally identifiable information of consumer 129 through transaction system 140 to financial institution 150 along with the payment information, and financial institution 150 can provide the information to merchant 119.In the same or other embodiments,

choose to fund 20% of the transaction from a demand deposit account (e.g., a debit account) and 80% of the transaction from a non-demand deposit account (e.g., by a charge to a credit account).", "In some embodiments, if an account of the one or more of consumer accounts 131 has an account balance that is less than the amount of the transaction (or the portion of the transaction that consumer 129 has chosen to allocate to the account), loan module 126 of mobile device 120 can determine that there is a deficiency and can present an option to fund the transaction (or a portion of the transaction) using a non-demand deposit account, such as a loan account, a credit account, or a points account.", "In other embodiments, loan module 126 can present the option for funding the transaction through a non-demand deposit account even if there is no deficiency in the one or more of consumer accounts 129.In some embodiments, the loan account can be a new account that is created upon consumer 129 choosing to fund the transaction (or portion thereof) with the loan account.", "In other embodiments, the loan account can be for a previously authorized loan.", "In some embodiments, the loan account can have a pre-existing loan balance, which can be increased based on the amount of loan used to the fund the transaction.", "In several embodiments, the loan can be a small loan, and can be labeled a “micro-loan”), but can be treated the same as credit line for a loan instead of an overdraw of an account.", "In several embodiments, consumer 129 can make the decision from which account or accounts to fund the transaction, and/or to authorize a loan or a credit transaction, while at or near the point-of-sale terminal 110 in the store of merchant 119.In the same or other embodiments, loan module 126 can allow consumer 129 to choose the one or more accounts from which to fund the transaction after consumer 129 has left the store.", "In many embodiments, financial institution 130 can fund the transaction temporarily from a shadow account that the bank uses to fund overdraft transaction, which can be reimbursed from the one or more accounts selected by consumer 129.For example, consumer 129 can authorize a transaction at point-of-sale terminal 110 in the store, and financial institution 130 can authorize transfer of funds to financial institution 150 to pay merchant 119, and after consumer 129 leaves the store of merchant 129, loan module 126 can push a message to consumer 129 asking for one or more of consumer accounts 131 that consumer 129 wants to use to fund the transaction.", "The options of consumer accounts 131 can include the option to open a new loan account, or to add to the balance of an existing loan account.", "In some embodiments, consumer 129 can setup a list (e.g., prioritized list) of consumer accounts 131 to use for transaction using mobile device 120, and/or can setup before-hand an amount and/or percentage to use from one or more of the accounts.", "For example, consumer 129 can choose to use a debit account for the first $50 and then use a credit account for the rest.", "As another example, consumer 129 can choose to use a debit account for 40% of the transaction, and use a new micro-loan for the rest.", "In some embodiments, a points account can be used to pay for all or at least a portion of the payment.", "For example, consumer 129 can have a points account at financial institution 130, which can have a balance of points earned by consumer 129 at financial institution 130.In many embodiments, these points can have an exchange value, such that the points can be redeemed to pay for all or at least a portion of the payment.", "In many embodiments, after mobile device 120 has communicated with point-of-sale terminal 110 using communication module 124 to receive the merchant identifier and other transaction information, and consumer 129 has authorized the transaction, mobile device 120 can communicate with financial institution 130 and/or transaction system 140, either directly or through mobile wallet provider 160, to request a payment be made to merchant account 151 of merchant 119 from one or more of consumer accounts 131.For example, when mobile device 120 communicates with financial institution 130 (either directly or through mobile wallet provider 160) to request a payment be made, account module 134 of financial institution 130 can determine account information about merchant account 151, such as the account identifier of merchant account 151, at least partially based on the merchant identifier received from mobile device 130.In some embodiments, financial institution 130 can communicate with transaction system 140 to get the account information about merchant account 151, which can be stored in merchant account database 141.In some embodiments, financial institution 130 can save the account information about merchant account 151 so financial institution does not need to query the account information from merchant account database 141 in transaction system 140 for future transaction involving the same merchant identifier.", "In other embodiments, financial institution 130 can query for the account information from merchant account database 141 in transaction system 140 for each new transaction, or at occasional and/or regular intervals.", "In other embodiments, when mobile device 120 communicates with transaction system 140 (either directly or through mobile wallet provider 160) to request a payment be made, transaction system 140 can provide the account information about merchant account 151 to first financial institution 130.In many embodiments, having the account information about merchant account 151, financial institution 130 can initiate a payment to financial institution 150 from one or more of consumer accounts 131 to merchant account 151.In several embodiments, before initiating payment, authorization module 133 can determine whether to authorize payment from one or more of consumer accounts 131.For example, financial institution 130 can determine whether the payment amount is within the available funds in one or more of consumer accounts 131, determine whether one or more of consumer accounts 131 is currently open and in good status (or closed), authenticate the identity of consumer 129 using mobile device 120, and/or perform other actions.", "For example, in some embodiments, authentication module 121 can authenticate the identity of consumer 129, and that information can be communicated from mobile device 120 to financial institution 130.In some embodiments, mobile device 120 can prompt consumer 129 to authenticate before and/or after mobile device 120 receives the merchant identifier and/or the transaction information from point-of-sale terminal 110.In some embodiments, authorization module 133 can request additional authentication from authentication module 121 (which can be directly through a network between financial institution 130 and mobile wallet 120, or can be through mobile wallet provider 160 and/or through transaction system 140) after receiving the request for payment from mobile device 120 and/or after receiving the information about merchant 119 and/or merchant account 151.In a number of embodiments, authorization module 133 of financial institution 130 can perform different and/or varying levels of authentication based on various factors.", "For example, authentication module 121 and/or authorization module 133 can determine whether mobile device 120 used to send the request for payment has been previously used by consumer 129 for transaction with financial institution 130, whether biometrics of the consumer match stored biometrics of consumer 129, whether the requested transaction and associated details (e.g., the identity of merchant 119, the location of merchant 119, the payment amount, the one or more items to be purchased (e.g., a list of SKUs), and/or other suitable factors) are consistent with spending patterns of consumer 129, whether consumer 129 has reported mobile device 120 lost or stolen, whether consumer 129 has reported that credit cards, debit cards, or other information about one or more of consumer accounts 131 have been lost or stolen, and/or other suitable factors.", "In various embodiments, financial institution 130 can adjust the level of authentication used to verify the identity of consumer 129 based on one or more of these factors, and/or based on the payment amount, the identity of merchant 119, the location of merchant 119, historical spending of consumer 129, and/or other relevant information.", "In some embodiments, if one or more of consumer accounts 131 chosen by consumer 129 for the transaction is short on funds or otherwise cannot be fully used, loan module 135 can communicate with loan module 126 to present other funding options to consumer 129, such as the option for a micro-loan to fund all or part of the transaction, as described above.", "In many embodiments, after receiving authorization from authorization module 133, financial institution 130 can initiate a payment to financial institution 150 to transfer funds from one or more of consumer accounts 131 to merchant account 151.In a number of embodiments, the payment can be effected by sending payment information regarding a payment to be made to merchant account 151 from one or more of consumer accounts 131.In a number of embodiments, the payment information transferred from financial institution 130 to financial institution 150 can effectuate an authenticated credit push, which can irrevocably satisfy payment to the merchant and/or ensure that the merchant has good funds when consumer 129 leaves the store of merchant 119.For example, the payment can be a settlement credit push of funds for the payment amount from one or more of consumer accounts 131 to merchant account 151, which can be settled immediately.", "In various embodiments, the payment information transferred from financial institution 130 to financial institution 150 can effectuate a push promise to pay, which can provide an irrevocable guarantee of payment from financial institution 130 to financial institution 150.In several embodiments, for example, the payment can be an ACH (Automated Clearing House) credit push, which can provide an irrevocable funding guarantee.", "In many embodiments, the payment and/or the guarantee of payment can be sent in real-time from financial institution 130 to financial institution 150, which can happen for each such transaction.", "In some embodiments, the settlement of the transaction can happen later, such as in a nightly batch fashion, and in some embodiments, can happen through a different network, such as an ACH network or a credit network.", "In other embodiments, the real-time payment and/or guarantee of payment can be processed through an ACH network or a credit network.", "In some embodiments, the consumer can provide instructions to financial institution 130 to label the transaction as a debit or a credit transaction in one or more of consumer accounts 131, and in some embodiments can provide such instructions with the request to pay, or before or after the request to pay.", "In some embodiments, a credit transaction can be treated as a micro-loan, as described above.", "In certain embodiments, a debit pull with guaranteed promise to pay can be used, such that financial institution 150 can receive a guaranteed promise to pay from financial institution 130 and pull the funds using a debit pull.", "In various embodiments, transaction system 140 can store information regarding each transaction in transaction database 142.In several embodiments, transaction system 140 can serve as a central auditor for transactions between the financial institutions (e.g., 130, 150) in data communication with transaction system 142.In some embodiments, transaction system 140 can receive some or all of the information from the merchant security transaction code.", "In various embodiments, one or more portions of the merchant security transaction code can be encrypted by security module 115.For example, the merchant security transaction code can include an encrypted portion that can be decrypted by security module 146 of transaction system 140, which can be used to ensure that the message has not been tampered.", "In other embodiments, the merchant security transaction code is not encrypted, but is digitally signed, as described above, and the digital signature can be verified, in some embodiments, by security module 146, which can advantageously ensure that the merchant identifier correctly identifies merchant 119, so that the funds are paid to merchant account 151 corresponding to merchant 119.In a number of embodiments, financial institution 150, upon receiving payment and/or guarantee of payment, can notify point-of-sale terminal 110 and/or merchant 119 in real-time that merchant 119 has satisfactorily received payment from consumer 129.For example, the notification can include various information, such as the transaction identifier, the amount received in payment (or guarantee), the merchant identifier, and/or other information.", "Receiving the notice of good funds can allow merchant 119 to proceed, such as, for example, to allow consumer to leave the store of merchant 119 with the items.", "In some embodiments, for example, point-of-sale terminal 110 can match the notification to the pending transaction in point-of-sale terminal 110 using the transaction identifier.", "In certain embodiments, merchant 119 can match the notification to the point-of-sale terminal using the merchant identifier.", "In some embodiments, consumer 129 can receive a notification on mobile device 120 that the transaction has cleared, such as shown in FIG.", "22 and described below.",

barrier plate component of the instant inventive termite baiting assembly is referred to generally by Reference Numeral 2.As depicted, the barrier plate 2 is circular, having a diameter between 4″ and 7″ and having a thickness between ⅛″ and ½″.", "The barrier plate 2 is preferably composed of plastic, and its preferred circular configuration is intended as being representative of other geometric shapes such as squares, hexagons, ovals, and the like.", "Peripheral wooden stake engaging apertures or eyes 4, 6, and 8 extend vertically through the barrier plate 2, and such plate preferably additionally includes a centrally positioned anchor stake aperture 10.Referring simultaneously to FIGS.", "1-3, wooden stakes 16, 22, and 28, are provided.", "Each of the stakes 16, 22, 28 preferably has a pointed lower end, and has an upper end which is held in engagement with the barrier plate 2.In addition to their plate anchoring and positioning functions, the stakes 16, 22, and 28 perform a function of providing a localized source of food for termites which causes them to dwell or remain at a subterranean locale directly underlying the barrier plate 2.Termites are known to feed upon pine wood and, in furtherance of their food source providing function, the stakes 16, 22, and 28 are preferably composed of pine wood.", "Preferred means for attaching the upper ends of stakes 16, 22, and 28 to the barrier plate 2 comprise the apertures 4, 6, and 8 in combination with flanged caps 12, 18, and 24.In the preferred embodiment, such caps respectively present downwardly opening sockets 14, 20, and 26.The outside diameter of socket 14 is preferably closely fitted to the inside diameter of aperture 4, while the inner wall of socket 14 is preferably slightly conically sloped in order to establish a tight pressure fit connection with the upper end of stake 16.Flanged cap 18 having socket 20 is preferably similarly configured for downward receipt within aperture 6 and for secure holding the upper end of stake 22.The assembly's third cap and socket combination 24,26 is similarly configured for engagements with aperture 8 and the upper end of stake 28.The above described aperture and cap combinations are considered to be representative of other suitably substituted stake mounting means such as screw connections, wholly formed sockets, pressure fitted eyes, and the like.", "In use of the instant inventive assembly, and referring in particular to Drawing FIG.", "4, a ground surface area 41 near the outer wall of a home to be protected by the instant inventive assembly is identified.", "At such ground area 41, a circular area of grass 3 may be cut by a homeowner to the level of the ground, such circular area matching the circular profile of the barrier plate 2.Thereafter, the homeowner may utilize a hand spade to dig a small pit 37 having a diameter of approximately 3″ and having a depth between 4″ and 6″.", "Thereafter, the homeowner may drop a provided body of termiticide 34 into the excavated pit 37, such body of termiticide 34 preferably comprising a mixture of diflubenzuron, noviflumuron, imidocloprid, fipronil, chlorfenapyr, lufenuron, hydramethylnon, sulfuramid, or hexaflumuron, and a termite edible inactive ingredient.", "In the preferred embodiment, the termiticide is encapsulated within a bag or closure 35 which is composed of a loosely woven natural fiber such as cotton, hemp, or burlap, which will allow through passage and ingress into the closure by termites.", "Thereafter, the homeowner may refill the pit 37 with dirt 36, burying the termiticide body 34.Thereafter, the homeowner may place the barrier plate 2 over the refilled pit 37, and may align the plate 2 so that its apertures 4, 6, and 8 peripherally surround the pit's upper edge.", "Thereafter, the homeowner may grasp wooden stake 16 and may cover the upper end of such stake with the socket 14 of flanged cap 12.Thereafter, the homeowner may extend the lower point of stake 16 through aperture 4, and may utilize a hammer to percussively strike the upper surface of the cap 12 and to drive the stake 16 and cap 12 downwardly until the socket 14 is nestingly received within aperture 4 as indicated in Drawing FIGS.", "3 and 4.During such stake hammering operation, the barrier plate 2 advantageously functions as a stake placement guiding template which assures that the stake 16 resides at the lateral periphery 39 of a thermal shadow zone 40 which is downwardly cast by the barrier plate into the ground 43.Stakes 22 and 28, and caps 18 and 24, may be similarly downwardly driven through apertures 6 and 8.Upon such downward driving of stakes 16, 22, and 28, such stakes advantageously perform additional functions of securely holding the barrier plate 2 and the associated thermal shadow zone 40 in volumetric alignment with the termiticide body 34.Upon installation as indicated in FIG.", "4, the barrier plate 2 additionally advantageously functions as a moisture evaporation barrier.", "The barrier plate's dual functions of producing and downwardly casting the thermal shadow zone 40 and blocking evaporation of ground moisture advantageously produce localized temperature and moisture subterranean environment factors which are sensed by termites which extend exploration tunnels in the vicinity.", "Termites may naturally horizontally extend

genomic loci in a single assay.", "In particular, the present invention relates to methods that provide sensitive and specific detection of target gene sequences or gene transcripts and methods that reveal both variant sequences and overall gene copy number in a single assay.", "Description of the Related Art Both complete human genome sequences of individual human subjects and partial genome resequencing studies have revealed the basic theme that all humans appear to possess less than perfect genomes.", "In particular, normal healthy human subjects are found to harbor hundreds if not thousands of genetic lesions within their genome sequences.", "Many of these lesions are known or predicted to eliminate the function of the gene in which they reside.", "The implication is that while normal diploid humans possess two functional copies of most genes, there are many instances in all humans where only one (or zero) functional gene copies are present.", "Similarly, instances where genes are overrepresented by gene duplication/amplification events are also encountered with significant frequency.", "One of the key features in biological networks is functional redundancy.", "Normal, healthy individuals can tolerate the average load of genetic lesions because they possess, on average, two copies of every gene such that loss of one copy is inconsequential.", "Moreover, sets of genes often perform similar functions such that minor perturbations in specific gene functions are generally compensated for within a larger network of functional elements.", "While functional compensation in biological systems is a general theme, there are many instances in which specific gene loss can trigger acute disruptive events.", "By way of example, cancers appear to be the consequence of genetic disease in which the compound effect of multiple individual lesions is uncontrolled cell proliferation.", "Similarly, prescribed medicines are often specific chemical entities that are transported, metabolized and/or eliminated by very specific genes.", "Perturbations in these genes, while generally inconsequential under normal circumstances, can manifest as adverse events (e.g., side effects) during chemical therapy.", "The central aim of “personalized medicine”, increasingly referred to as “precision medicine,” is to merge genetic information that is specific to the patient with treatment options that are compatible with the individual's genetic profile.", "However, the vast potential of personalized medicine has yet to be realized.", "To realize this goal, there must be clinically acceptable, robust genetic diagnostic tests that can reliably determine the genetic status of relevant genes.", "BRIEF SUMMARY OF THE INVENTION Particular embodiments contemplated

multifunctional adaptor module) with a single amplification sequence on both ends of the genomic fragment has several significant advantages, including the fact that the same genomic fragment is tagged independently on its two ends.", "As described in the next few sections, the two strands of any given fragment are eventually separated from one another and will behave in the present invention as independent molecules.", "Therefore the presence of two different tags at the two ends of the same fragment becomes an advantage rather than a liability of the present invention.", "Additionally, there is the fact that adaptor-to-adaptor ligation events are a huge problem in next-generation library construction where the initial goal is to create amplicons with dissimilar ends.", "Using the methods of the present invention, the methods introduce this asymmetry later in the process and therefore identical ends are acceptable with the present invention.", "An unforeseen and surprising benefit of the present methods is that adaptor dimers are not observed in the library construction methods of the present invention.", "While not being bound by theory, present inventors contemplate that this may be because the rare adaptor dimer species that are formed rapidly form tight hairpin structures during the steps of denaturation and annealing that are necessary for PCR amplification and it is further contemplated that these hairpin structures are completely resistant to further primer-directed amplification.", "The ability to make adaptor-dimer free libraries is a significant technical feature in extremely low input applications like single-to-few cell genomic analysis, circulating DNA analysis (as in fetal diagnostics, tissue transplantation rejection surveillance, or cancer screening applications) or single cell transcriptome analysis.", "As such, the present methods provide significant utility in such applications.", "An additional significant feature of single-primer amplicons is that it is possible to “turn on” amplification with a PCR primer of 25 nt and to “turn off” amplification with a longer 58 nt primer.", "This is described in more detail, and the significance to the present invention is highlighted, in section 6-5 below.", "Overall The adaptor strategy in which a single universal amplification sequence is used on both ends of target fragments eliminates issues with adaptor dimer.", "This is clearly demonstrated by way of example in Example 3: Construction of single-adaptor genomic library.", "Section 3: Library Quantification An additional aspect of the present methods for genomic analysis strategy is that the “coverage depth” is known, that is, the average number of genomic copies present in a library are known or can be determined.", "The cover depth is measured using purified ligation reactions prior to the bulk amplification of the library that is necessary for subsequent steps.", "By way of illustration, if 50 genomes worth of DNA is put into the library scheme of an embodiment of the present invention and there is 100% efficient ligation of adaptors to both ends of the fragments, then the coverage depth is 100 because each adaptor end acts independently of the other, then 2 ends times 50 genomes=100 in coverage.", "The simple fact that adaptor-dimers do not amplify with the universal PCR primer contemplated herein but fragments adapted on both ends do means that library quantitation will simply be a matter of measuring library complexity with quantitative PCR (qPCR) using universal primer and calibrating the results against standards with known coverage depth.", "Here the phrase “genome copies” and “coverage depth” mean the same thing and may be used interchangeably.", "The present methods will carry forward anywhere from 4-1000, preferably 20-100 fold coverage depth into the next phase of sample processing according to the present invention.", "Section 4: Library Amplification In particular embodiments, a portion of the adaptor ligated genomic fragment library equivalent to 20-100 fold coverage depth will be amplified using standard PCR techniques with a single, universal primer sequence driving amplification.", "At this stage it is advantageous, in particular embodiments, to convert the picograms of material in the initial library into micrograms of amplified material, implying a 10,000-fold amplification.", "Section 5: Hybridization of Target Library Fragments to Capture Probes Advances in oligonucleotide synthesis chemistries have created new opportunities for sophisticated genome capture strategies.", "In particular, the availability of long oligonucleotides (100-200 nt in length) that have reasonable per base synthesis costs, relatively high yields, and exquisite base accuracy are now commercially available from a variety of vendors.", "This capability has the present inventor to create multifunctional capture probes (FIG.", "2).", "The elements of an illustrative example of a multifunctional capture probe comprises: Region 1 comprises a 34 nt region common to all probes that hybridizes to a modified complementary oligonucleotide (also referred to as a partner oligonucleotide).", "This modified oligonucleotide further comprises on the 5′ end a biotin—TEG modification that is a biotin capable of binding tightly to streptavidin protein, a long hydrophilic spacer arm that alleviates steric hindrance of biotin binding.", "On the 3′ end, the oligonucleotide terminates with a dideoxy-cytosine residue that renders this partner oligonucleotide inert to primer extension.", "This element of probe design allows for adapting an unlimited number of probes with biotin capture functionality without having to directly modify said probes.", "Region 2 comprises custom 60 nt regions that are target-specific and that interact with gDNA fragment molecules.", "This region is designed by computational methods that account for uniqueness of sequence within the genome, the presence of common SNPs that may compromise binding efficiency, and secondary structure considerations.", "Region 3 comprises a 20 nt segment that will serve as a PCR primer binding site in subsequent fragment amplification.", "This feature is described in further detail in the next paragraph.", "A multiplicity of probes can be used to capture genomic regions of interest (multiplexing of probes).", "At least two probes may be employed to thoroughly query a typical coding exon of 100-150 bp in length.", "By way of example, this indicates that 20 probes will be used to capture a typical 10 exon gene and a total of 2000 probes will be used to interrogate a 100 gene panel.", "The hybridization of genomic library fragments to probes can be performed by thermal denaturation followed by reannealing.", "In one embodiment, the steps comprise: 1.Combining genomic library fragments with pooled probe sequences (in this case “probe sequences” refers to the combination of individual probes together with an equal molar quantity of the highly modified partner oligonucleotide) at a specific target to probe ratio ranging anywhere from 1 part target to 1 part probe to 1 part target to 1,000,000 parts probe.", "In one embodiment, the optimal ratio is about 1 part fragment to 10,000 parts probe.", "2.Heating the combined fragment+probe in a solution containing 1M NaCl, 10 mM Tris pH 8.0, 1 mM EDTA and 0.1% Tween 20 (non-ionic detergent) to 95° C. for >30 sec to denature all double-strand DNA structure.", "3.Cooling the combined probe and fragment in controlled steps, for example 1° C. decrease in temperature every 2 minutes, down to <60° C. This slow cooling will result in duplexes between target genomic fragments and probe sequences.", "4.Binding of the probe: fragment complexes to carboxyl coated, streptavidin modified paramagnetic beads and “pull out” of these beads using a strong magnet.", "5.Washing of the bound complexes with a solution containing 25% (v/v) formamide, 10 mM Tris pH 8.0, 0.1 mM EDTA and 0.05% Tween 20.In particular embodiments, the wash step is performed at least twice.", "6.Resuspension of the washed beads in a solution that is amenable to the subsequent enzyme processing step(s).", "Capture Reactions: Embodiments of the capture reaction are demonstrated in Example 3 (Construction of single-adaptor genomic library) and employ qPCR assays developed and further described in Example 5 (Validation of PLP1 qPCR assays).", "Section 6: Enzymatic Processing of Hybridized Probe: Target Complexes As currently practiced in the art, hybridization-based sequence capture methods generally result in a suboptimal enrichment of target sequences.", "From literature and commercial publications it can be estimated that, at best, about 5%-10% of reads map to their intended target sequences.", "The remaining reads often map near the intended target and commercial vendors have resorted to redefining “on-target” as reads that land anywhere within ˜1000 bases of the intended locus.", "The reasons for this “spreading” effect are incompletely understood, but they are likely a result of legitimate sequence hybridization events (see, e.g., FIG.", "3).", "The enzymatic processing of complexes as contemplated herein more sharply focuses the captured sequences on the exact regions of interest.", "In this step, a DNA polymerase that also possesses a 3′ to 5′ exonuclease activity is employed.", "An illustrative example of such an enzyme is T4 DNA polymerase.", "This enzyme will “chew off” dangling tail sequences down to the duplex region formed between the probe and target sequence.", "It will then copy the tail segment on the probe.", "See, e.g., FIG.", "4.Benefits provided by this step include, but are not limited to: 1.By employing this type of enzymatic processing, only those fragments that were in direct, duplexed hybridization with probe will be carried forward.", "The final sequencing library is a chimeric (hybrid) set of molecules derived from both the fragment and the probe.", "2.The probe is strand-specific and therefore the captured target has an inherent directionality to it (illustrated in FIG.", "5).", "This means that only one of two strands generated from a single fragment will interact with probe, and processing will “focus” reads to a region 5′ of the probe sequence.", "At this point, the complementary strand of the fragment becomes a completely independent species.", "By placing directional probes on either side of a target region (e.g.", "an exon), the technology enables highly specific focusing of sequencing reads on target regions (FIG.", "6).", "3.Target molecules that are legitimately cross-hybridized with target fragments (but not with probe; FIG.", "3) do not acquire essential probe sequence and are therefore lost in the subsequent amplification step.", "4.The actual “tail” sequence of the probe becomes copied into target fragments as part of the amplification sequence.", "All commercially practicable sequencing platforms (e.g.", "Illumina's reversible terminator chemistry sequencing platforms) require sequencing libraries in which the target fragments have asymmetric ends; this is often referred to as a “forward” and a “reverse” adaptor sequence, or in the shorthand of sequencing labs, “P1” and “P2”.", "In particular embodiments, up to this point, fragment libraries contemplated herein have a single species on the end; called “P1”.", "The enzymatic processing step achieves two things.", "First, it “erases” (by 3′ to 5′ exonuclease activity) one of these P1 ends.", "Second, it “adds” (by DNA polymerase copying of the probe tail sequence) the basis of a P2 end that is dissimilar from P1.5.Enzymatically-modified target molecules with legitimate P1-P2 ends can be selectively enriched in the PCR amplification step that follows processing.", "This is achieved by the use of long PCR primers.", "In particular long primers are necessary to add the full functionality required for next-generation sequencing, and they also confer selectivity to amplification.", "Residual P1-P1 library fragments that are “contaminants” from the first round of amplification fail to amplify with longer P1 primers.", "This is a significant advantage of the present method.", "The initial P1-P1 library amplifies effectively with a single, 25 nt PCR primer.", "When this primer length is extended to 57 nt—to add sequencing functionality—these same P1-P1 molecules are not amplified to any appreciable extent.", "Therefore amplification of the initial library can be “turned on” with a 25 nt primer and “turned off” with a 57 nt primer.", "Overall The inability of P1-insert-P1 libraries to amplify is demonstrated Example 3 (Construction of single-adaptor genomic library).", "The preferential amplification of P1-insert-P2 processed DNA fragments is shown in Example 3 (Construction of single-adaptor genomic library).", "Example 3 further demonstrates the substantial improvement in target specificity that accompanies processing.", "Finally, the “sensitivity” of processing, meaning the percent of initial complexes that are processed, is demonstrated to be on the order of 10% of all captured complexes in Example 9 (Direct measurement of post-capture processing).", "Section 7: Amplification and Sequencing The core adaptor and primer sequences applied to initial proof-of-concept experiments are shown in Table 2.Enzymatically processed complex from step 6 is added directly to a PCR amplification reaction that contains full-length forward and reverse PCR primers.", "Following amplification, the library can be purified, quantified, loaded on a high-throughput, next-generation sequencer (in this embodiment, the libraries are configured for the Illumina

least two opportunities to interrogate and analyze biological samples.", "One well-established aspect is determination of DNA sequences, meaning the de novo sequences present in the sample (e.g., the sequencing of a newly isolated microbe) or the resequencing of known regions for variants (e.g., the search for variants within known genes).", "A second aspect of massive parallel sequencing is quantitative biology and the ability to count the number of times a particular sequence is encountered.", "This is a fundamental aspect of technologies like “RNA-seq” and “CHIP-seq”, where counting is used to infer gene expression or the association of a particular protein with genomic DNA, respectively.", "This example relates to the quantitative, counting-based aspects of DNA sequencing.", "DNA fragments are most often counted as constellations of sequences that share high degrees of similarity (i.e., they align to specific regions of a known genomic sequence).", "Often the sequences within these clusters are identical.", "Note that DNA sequences with either a) different starting and ending DNA sequence reads or b) with high quality sequence differences from other reads within the set are most often considered “unique reads”.", "Thus, different starting sequence location and sequence variation are one form of “tagging” that is used to differentiate unique events from clones.", "In the present example, random nucleotide tags (e.g., random six nucleotide sequences) are also introduced onto genomic fragments during the course of library construction.", "The combination of 1) the random nucleotide tag sequence with 2) the start point of the DNA sequencing read and 3) the actual sequence of the read collectively make up a tag.", "This tag enables one to differentiate between convergent events where the same fragment was cloned twice (such fragments will have different random nucleotide tag sequences that were introduced during library construction) and fragments of the same origin that were replicated during library amplification (these “clones” will have the same random nucleotide segment and the same clone start points).", "This type of tagging further enables quantitative analysis of genomic DNA specifically, and populations of DNA molecules (e.g., RNA-seq libraries) more generally.", "The introduction of random nucleotide tags (random Nmer combined with DNA clone ends) into DNA sequencing libraries allows, in theory, each unique clone within the library to be identified by its unique tag sequence.", "The specification of“in theory” acknowledges confounding features of ordinary experimental data sets that may occur such as errors in sequencing, errors introduced during library amplification, introduction of contaminating clones from other libraries, etc.", "All of these sources can and will confound the theoretical consideration posed here.", "In the context of sequence capture and targeted resequencing, the tagging of libraries can enable quantitative analysis of locus copy number within a captured library.", "Consider, by way of non-limiting example, a library constructed from the equivalent of 100 diploid genomes of input that was created from a male subject.", "The prediction is that approximately 200 library clones will be present at each autosomal locus, and 100 clones will be present at each X-chromosome locus.", "If an autosomal region is captured and sequenced 2000 times, then all 200 tags will be encountered with a confidence interval exceeding 99% certainty.", "For the X-chromosomal region, 2000 reads would, in theory, reveal a total of 100 tags.", "By way of illustration, this example supports the general concept that the creation of DNA tags within a DNA sequencing library can preserve copy number differences.", "This general framework can be applied to the methods described herein.", "Empirical evidence suggest that adjustments may need to be made for differences in cloning efficiencies on a locus-by-locus basis, for sporadic introduction of artifactual tags from experimental error, etc.", "The implementation of this concept into practice may differ in different contexts and may involve case-by-case sequence analysis methods, but the general principle outlined here will underlie all such applications.", "To this point, the creation of tagged DNA libraries has been considered in the context of genomic DNA analysis, yet it must be emphasized that this concept applies to all counting-based DNA sequencing applications.", "In particular embodiments, tagging may be applied to RNA-seq,

significant features of the present methods for adaptor design.", "In particular, the adaptor-alone ligation reaction had no detectable adaptor dimer species present.", "This was very significant in the context of extremely low input sequencing library preparation technology, as with current methods, the limits of input are invariably determined by the background levels of adaptor dimer.", "Highly specialized technologies have been applied in attempts to keep adaptor dimer contamination in check.", "These include size exclusion methods such as columns or gel purification, expensive

library construction.", "The simple, single adaptor, single primer concept contemplated herein addresses the adaptor dimer issue with a simple solution that evokes the basic principles of DNA structural principles.", "This extremely low input technology will be useful for the construction of genomic libraries for genomic analysis, for transcriptome analysis of cloned double-stranded cDNA

12.The second pool was generated as described for the ‘capture only’ library in Example 12 except for the following modification.", "After capture, a second round of PCR was performed to convert single primer, ACA2-amplified libraries into dual primer, heterologous end libraries suitable for Illumina sequencing.", "To do this, libraries were diluted and re-amplified with the following primers: primer #55 AATGATACGGCGACCACCGAGATCTACACGTCATGCAGGACCAGAG (SEQ ID NO: 199) and primer #56 CAAGCAGAAGACGGCATACGAGATGTGACTGGCACGGGAGTTGAGAATTCGAATAC A (SEQ ID NO: 200).", "The 100 μL reaction mix contained 40 ng of library, 10 μL of 10×STD Taq buffer, 10 μL of 25 mM MgCl2, 10 μL of 55 and 10 μL of 56 primer that were both at 10 uM, 5 μL of DMSO, 5 μL of dNTP and 1 μL of Taq DNA polymerase.", "The samples were amplified for 2 cycles of 94° C.-30 sec, 50° C.-30 sec, 52.5° C.-30 sec, 55° C.-30 sec, 57.5° C.-30 sec, 60° C.-30 sec, 72° C.-1 min.", "They were then amplified for 8 cycles of 94 C-30 sec, 60 C-30 sec and 72 C-60 sec followed by 72° C. for 2 min.", "PCR mixes were purified with beads and resuspended in 50 μL each.", "Results and Discussion: Both pools were analyzed using an Illumina MiSeq Personal Sequencer.", "The 50 nucleotide sequence reads from each library pool were trimmed to remove 4 base barcode sequences and mapped to the human genome reference sequence (version hg19) using the Bowtie sequence alignment program.", "Approximately 80% of reads in both libraries aligned unambiguously to the reference sequence.", "Further characterization of aligned reads revealed that coupling hybridization-based capture with enzymatic processing resulted in a 979,592-fold enrichment of the 4.9 kilobase target region relative to the input genomic DNA.", "This represented a 3-fold improvement in library content when compared to the unprocessed, ‘capture only’ approach.", "Overall, nearly 4 out of 5 sequences obtained by this alternative processing method mapped to genomic sites that were specifically targeted by capture probes.", "A summary of alignment statistics for each library pool are shown in FIG.", "53.Reads from each library pool were also displayed in the UCSC Genome Browser to assess local sequence coverage and distribution around target sites.", "A close-up view of two segments of the X chromosome shows that processed libraries produced sequence coverage that was more highly concentrated within targeted sites than ‘capture only’ libraries did (FIG.", "18).", "Moreover, the sequences mapping to target regions were more uniformly distributed in the processed libraries than the unprocessed controls.", "Taken together, these data indicated that the alternative processing method dramatically improved the quantity and quality of target sequences present in enriched libraries.", "Example 14: Bioinformatics Overview: Traditional Next Generation Sequencing (NGS) analysis is “vertical.” The unique design of the inventive molecules contemplated herein enables a “horizontal” approach that will revolutionize the approach to clinical resequencing.", "“Vertical” as used herein, with regard to sequence alignments, refers to approaches exemplified by FIG.", "19.Previous approaches to informatics analysis involve a first step in which short reads are aligned to a reference genome.", "Following alignment, overlapping reads are analyzed for base changes that may be indicative of a SNV (single nucleotide variant).", "The approach was nick-named here as “vertical” because it relies on alignments that are often depicted as vertical stacks of reads.", "Various programs make allowances for SNVs and Indels (insertions/deletions), but the core approach is alignment-recognition-based.", "In contrast, the paired-end read data obtained by the methods contemplated herein will have DNA tagged sequence information in read 1 and probe ID information in read 2.The first step in data analysis is to match reads to probes.", "Step two is analyzing the sequence information connected “horizontally” to each probe.", "See, e.g., FIG.", "20.At sufficient read depth, horizontal, probe-based sequence association does not rely on alignment.", "Rather, reads can be assembled into contigs de novo.", "The advantage of the method is that it is extremely robust to insertions/deletions and multiple sequence changes in a short stretch of sequence, both situations where conventional, alignment-based methods struggle and have the most difficulty detecting.", "Moreover, the combination of horizontal association with probes and tagging facilitates more accurate hypothesis generation (i.e., determination if an observed sequence variant is likely to be true or false).", "CNV and Structural Variation I: In large scale copy number variation (CNV) analyses, the method comprises determination of unique read numbers associated with captured sequence regions.", "The vast majority of observed CNV is “micro-CNV” that involves base insertions and deletions that are on the order of 2-100 bp in length.", "Vertical alignment methods struggle with micro insertions/deletions (indel) because they require relaxation of alignment stringency that promotes large numbers of false-positive hypotheses.", "Horizontal methods and de novo contig assembly require no such relaxation of alignment parameters and they demand that structural variation is accounted for.", "Consider the simple case of a small insertion within one allele of an exon, as exemplified in FIG.", "21.In this example, horizontal alignment “forces” reads to be associated with probe 1 and probe 2.Assembly will generate two contigs, one with a wild-type exon structure and one with an insertion structure.", "Two principles emerge from this analysis: 1) Overlapping reads from adjacent probes will support or refute the hypothesis of an indel-containing allele of the captured exon; and 2) micro-CNV alleles outside of capture probes are readily detectable by horizontal methodologies.", "CNV and Structural Variation II: Validation of CNV often involves vertical alignment methods.", "In these studies, typically perfect alignments to a reference sequence are demanded.", "Such methods are vulnerable to SNVs (such as common SNPs) where reads crossing SNVs that differ from the reference will be discarded.", "The net result will be chronic underestimation of copy number.", "The horizontal methods possible with the present invention methods should be used going forward.", "Horizontal hypothesis testing of SNVs I: Vertical, alignment-based methods for SNV detection are difficult to analyze.", "Homozygous variant alleles involving a single base are fairly straightforward to identify, but these changes are rare.", "More commonly, SNVs are heterozygous, and variants may occur at several contiguous or closely spaced positions (error prone repair tends to lay down tracks where several bases are non-consensus).", "The heterozygous SNV hypotheses run the spectrum from true, high coverage detection where (strictly as an hypothetical example) 49 reads possess a SNV and 47 reads possess the wild-type, reference base.", "Calls become much more speculative when read depth thins and the numbers of SNV versus WT reads deviate significantly from 50/50 (e.g., 10 total reads where 8 are WT and 2 are variant).", "Hypotheses nominated for orthogonal validation are invariably subject to an arbitrary cut-off.", "In particular embodiments, where horizontal probe-based association is combined with tags, far greater granularity in SNV hypotheses is achieved.", "SNVs that reside on a single tag (tag=code+end-point), especially in cases where reads within the same tag are WT, are disregarded.", "See, e.g., FIG.", "22.Horizontal hypothesis testing of SNVs II: SNV hypotheses that arise on two different tags, even if the read start sites are identical (A), or that arise on different reads that horizontally associate with the same probe (B), or that arise from different probe associations at the same exon (C) are necessarily hypotheses that must be seriously considered.", "See, e.g., FIG.", "23.Example 15: Molecular Annotation Overview: This example describes the interplay between “molecular annotation” of sequencing libraries (FIG.", "24) and the informatics used in subsequent steps to evaluate the resulting sequencing information.", "The reverse read from a probe has utility.", "Reverse read 2, which determines the DNA sequence of the probe region, has significant utility in all downstream analysis considerations.", "For example, utility can be found in variant calling and the output from this in copy number determination.", "These two aspects of data analysis are described below.", "Read 2 Probe Sequence: A probe set is a unique and known collection of sequences, which can include one or two probes or even tens of thousands of probes.", "This means that read_2 can be used to identify any and all of the probes within an experiment.", "This of course assumes that read 2 is of sufficient length and that probes are designed such that the region interrogated by read_2 constitutes a unique identifier.", "Table 26 describes a collection of 192 probes and the 10 nt read_2 sequence that serves as a unique identifier for each probe.", "Note that two probes (CYP2C19_r5_F and CYP2C9r5F) naturally share identical 10 nt 5′ DNA sequences, and a 2 nt code of “AG” or “CT” was added to distinguish between them.", "TABLE 26

in FIG.", "24) is present because it was associated with a particular probe (part (5) in FIG.", "24).", "Taken in total, this data indicates that each DNA sequence present in a collection of next-generation sequences can be associated with the probe sequence that targeted it.", "All DNA sequences associated with a particular probe can be retrieved.", "The present paradigm for next-generation resequencing analysis (targeted or otherwise) is to align reads back to a reference genome.", "Knowledge of the targeting probe association affords a novel workflow in which reads are first sorted by probe and then analyzed by either alignment-based methods, de novo assembly methods, or both.", "As described in Example 14, probe-associated-read-scaffold-assembly (PARSAR) solves one of the more complex and difficult issues in variant discovery, which is that the most interesting variants are those that deviate most significantly from the reference sequence, yet these are the very sequences that will be most refractile to conventional sequence based alignment (FIG.", "25).", "Using probe-association followed by de novo local assembly, such variants are easily identified.", "Probe-based read grouping is used in conjunction with other aspects of molecular design to identify variants with a high-degree of first-pass confidence.", "As shown in FIG.", "26, probes are generally designed to bracket target regions.", "The overlapping aspect of reads allows potential variant sites to be queried by independent reads in both orientations.", "In addition, this dual-probe design ensures that adjacent probe binding sites themselves are sequenced.", "This is an important feature where probe capture performance may be in question.", "As an example, variant alleles where single nucleotide variants underlie one of the capture probe sequences are identified by this molecular design and can be accounted for in downstream informatics analysis.", "An additional aspect of flow of information from molecular annotation to downstream variant analysis involves sequence “tags”, defined as the combination of a three base sequence label and ragged sequence start sites ((1)+(3) in FIG.", "24).", "Sequence tags define the uniqueness of each sequencing clone.", "As illustrated in FIG.", "27, variants that occur within a collection of sibling clones that share identical sequence tags are likely to be false positives.", "In contrast, variants are shared among sequences with different tags—even if they occur at low frequency—have a higher probability of being true positive variants.", "This system of tagging sequences and using tags to assign confidence predictions to variant calling has the prospect of substantially decreasing the burden of downstream variant validation (which can be costly and time consuming).", "Molecular annotation is described in more detail in the document Example 16, which describes the molecular technology sequencing platform.", "In summary, one of the distinguishing features of the technology platforms contemplated herein is the fact that all “annealing probe” events are copied into DNA clones that also possess additional molecular annotation.", "Sequences are segregated by probe and by sample labels into a collection belonging to a specific target region of a specific input sample.", "Combinations of alignment and de novo assembly can then be used for variant detection.", "Finally, redundancy in the appearance of candidate variants can be used to assign confidence in variant calling.", "In addition to variant analysis, methods for copy number determination were also provided.", "These two elements are tightly coupled, specifically because copy number determination is dependent on high confidence sequencing reads.", "The overall schema for determining copy number from sequence information is shown in FIG.", "28.Example 16: Molecular Technology Sequencing Platform Overview: The genomic sequencing platforms contemplated herein provide methods to: (1) Address genomic samples from multiple individuals in a single sequencing run; (2) Detect single (and/or multiple) nucleotide variants (SNVs) and single (and/or multiple) nucleotide insertions and deletions (SNIDs) with high confidence; (3) Detect large and small scale copy number variations (CNVs) in all queried gene environments; (4) Detect micro-scale translocations, inversions and insertion/deletion events in queried gene environments; (5) Develop a technological system that is scalable from ≥exome-scale investigation (≥1-2% of the overall human genome sequence) to ≤single gene-scale validation; (6) Achieve high specificity (low false-negative rate) and high sensitivity (low false-positive rate) in genomic variation tests; (7) Create a molecular and bioinformatics technology that is simple, portable and scalable in its execution; and (8) Provide molecular methods that are readily amenable to quality control measurements.", "The overall schematic of genomic sequencing read is shown in FIG.", "29.A description of each element is as follows: (1) The “sequence label” is a set of (contiguous*) nucleotides (i.e.", "a unique set of 3 mers) that is used in conjunction with the read start position (3) to establish the uniqueness of each sequencing read.", "In founding documents, the combination of this label and the read start point were referred to as the “unique sequence tag.” Because the sequence label is the first set of bases encountered and in sequencing-by-synthesis (SBS) chemistry all four DNA bases must be equally represented at each read position, the constraints on the sequencing label are not only uniqueness, but also that the collection of bases used in the collective set of sequence labels must have all four bases present at all positions sequenced.", "The use of unique sequence tags to determine local CNVs is described in the bioinformatics section of this document.", "(2) The “sample label” is a set of (contiguous*) nucleotide codes that uniquely identify a particular sample within a set of multiplexed samples.", "As with the sequencing label, the collection of sample labels must also contain all four bases to satisfy the requirements of SBS sequence base calling.", "The sample codes are intentionally positioned next to genomic DNA fragments.", "The driver for this design is ligation bias, meaning that there are base preferences for DNA ligation efficiency in the ˜2 bases upstream and the 1-2 bases downstream of the ligation junction.", "By placing the sample code at the ligation junction, all fragments within a specific sample experience the ligation influences/biases.", "*—Without wishing to be bound to any particular theory, it is contemplated that the sequence labels and sample labels could be created as inter-digitated nucleotide sequences.", "(3) The “read start point” within genomic fragments is one of two key elements that define a “unique sequence read.” As discussed in section (1) above, the unique identifying “tag” for each read is comprised of the sequencing label AND the read start point.", "As considered in more detail below, the collection of unique [(1)+(3)] sequence tags is essential for determination of large scale CNV.", "Here “large scale CNV” is defined as any CNV that involves the entirety of at least one probe binding region plus some adjacent sequence.", "Large scale CNV can be as large as gain or loss of entire chromosomes.", "[(1)+(2)] The sequence label and sample label are embedded in adaptor sequences that are ligated to end-repaired genomic fragments in the initial stage of library construction process where a whole genome library is created.", "(4) The sequencing read.", "The sequence information from genomic fragments is, of course, a central focus of the genomic assays.", "Each read is considered in the context of multiple, overlapping reads produced within the same assay.", "(5) The probe level—“genomic indexing.” The overall genomics assay strategy is to combine multiple sequence labels into a composite “molecular annotation” that places each sequencing read into a larger framework of genomic analysis.", "Within this operational paradigm, Read 1 reveals elements (1-4) of each annotated clone.", "Read 2 reveals the probe sequence that retrieved each clone by hybridization based capture and subsequent enzymatic processing.", "The probe sequence information is central to the genomics strategy because all reads are initially clustered according to the probe that captured them.", "This clustering of information on a probe-by-probe basis is termed “genomic indexing” because each read is indexed to a genomic probe prior to analysis.", "One of the interesting features of the probe label is that the constellation of all probe sequences within a capture reaction is well-defined (we know which probes went into the capture reaction).", "This implies that Read 2 does not necessarily need to cover the entire 60 nt probe sequence.", "Rather, Read 2 only needs to be of sufficient length to enable unambiguous identification of all probes within a specific reaction.", "As one non-limiting example, the probe set discussed in Example 15 consists of 192 probes that can be differentiated based on only 7 nt of 5′ probe sequence (two of the probes with identical 7 nt 5′ termini were tagged with dinucleotide codes so they could be informatically differentiated).", "(6) The capture label.", "The composition of the libraries is determined by the intimate molecular interaction between probes and target sequences.", "The performance of each unique probe sequence can be monitored using the capture label, which can be as simple as a string of several (4-6) random bases.", "The diversity and statistical distribution of capture labels detected in sequencing is a direct measure of probe performance.", "By way of example, imagine a case where very few sequences are associated with a particular probe sequence.", "It may be tempting to attribute this deficit of sequences to poor probe performance, and therefore to initiate iterative cycles of probe redesigns.", "However, sequence under-representation may also be a consequence of sequences that do not ligate well to adaptors and or sequences that do not amplify well with the particular PCR regimen that is used.", "The use of capture labels allows differentiation of these failure modes.", "With poor probe performance, the very few capture events that do occur will manifest as very few capture labels that show up multiple times.", "In contrast, poor representation for reasons upstream of the actual capture reaction (ligation, PCR, end-repair, etc.)", "will result in a large constellation of capture labels that will be, by and large, uniquely represented.", "In particular embodiments, as one transitions into automated designs of thousands of probes, the ability to informatically QC probe performance will become increasingly important.", "Example 17: Probe Selection and Implementation Summary: Probe sequence selection and the methods to use them have, necessarily, been developed in concert.", "This example describes probe selection criterion in Section I and the laboratory methods that make them most effective in Section II.", "See, e.g., FIG.", "30.Section I.", "Selection of Targeting Probes.", "In the most general terms, target enrichment probes are 60 nt in length.", "Probes are generally directional, meaning they capture sequences on one side (generally the 3′ side) of their position.", "Tail sequences that add additional functionality (e.g., PCR primer binding site, binding site for complementary oligo that enables biotin pull-out, etc) are added in addition to the core targeting 60-mer.", "Sixty nucleotide targeting sequences are chosen with the following constraints and criterion: (1) The probe is positioned from −100 to +50 nt relative to the start of the target sequence.", "In FIG.", "30, the “start” of the target sequence is the intron:exon junction; (2) Probes are designed with redundancy, as illustrated, such that the resulting sequences from a pair of probes are overlapping in opposite orientations; (3) Probes are selected (where possible) to possess GC content not less than 33% (>20 G's or C's per 60 mer) and not more than 67% (<40 G's or C's per 60 mer); (4) Probes are selected to avoid repeats wherever possible.", "This is done with the help of REPEATMASKER and/or unique alignability criterion, both of which can be viewed on the UCSC genome browser; and (5) In case the position requirement, GC requirement, and the uniqueness requirement cannot be met, selection rules are relaxed in the following order (GC>position>uniqueness).", "In other words, GC and positioning are flexible; the uniqueness criterion is not.", "Section II.", "Laboratory Methods.", "The input to target enrichment is probes, a gDNA library, and buffers, which have been described elsewhere herein.", "The first step in targeted enrichment is melting of the gDNA library, which begins in a form as double-stranded PCR fragments.", "This is achieved by denaturation of the gDNA, preferably at a concentration of 100 ng/μL in a total volume of 10 μL, at 98° C. for 2 min followed by immediate transfer to ice.", "The gDNA library is suspended in a low salt buffer that contains 10 mM Tris pH 8.0 and 0.1 mM EDTA.", "The second step is to add 5 L of concentrated binding buffer (4M NaCl, 40 mM Tris pH 8.0, 0.4 mM EDTA and 0.4% Tween20).", "While these conditions are specific, the overarching concept is that the concentration of salt must be increased to 2N osmolarity to achieve rapid kinetic association of complementary DNA strands.", "Five microliters of probe is also added such that the final concentration of probe is 250 pM in each probe.", "The mixture of gDNA library, buffer and probe is heated to 98° C. for 2 min and cooled in 1° C. increments for four min each down to 68° C. In the third step, probe:gDNA complexes (the probe has a biotin associated with it) are bound to magnetic beads that are coated with streptavidin.", "In the fourth step, stringent washing is used to remove unwanted associations between probe and non-target sequences that may occur because of, for example, short matches of nucleotide sequence between probe and gDNA.", "Stringency is achieved by using low-salt, high-formamide wash buffer as, for example, a buffer containing 30%-35% formamide (v/v), 10 mM Tris pH 8.0, 0.1 mM EDTA and 0.5% Tween 20).", "Several washes of the beads are used to achieve the desired purity of target sequence (e.g., four).", "The washed beads possess target sequences bound to probe that are processed, amplified, and sequenced.", "In summary, low salt melting of the gDNA library, high salt probe annealing, and high formamide washes are used in concert with probe designs to achieve high levels of target sequence enrichment.", "Example 18: Exemplary Sequences

contemplated herein.", "In this embodiment, DNA repair is used to attach probe-associated sequences to captured genomic fragments.", "This approach worked well for creating sequence-ready targeted genomic libraries.", "Concept: An important principle of the library construction is that the sequence ready clones are comprised of DNA sequences derived from both genomic fragments and capture probes.", "This “recombination” of parts greatly enriches for those genomic fragments that are in direct contact with probe, and it enables focused sequencing reads on one side of a probe sequence.", "In this design, the tripartite complex formed between the target genomic library fragment, the capture probe and the common partner oligo possesses a structure reminiscent of a DNA replication fork.", "Such forks occur during normal DNA replication, but they also occur during DNA repair processes.", "In the latter case, it is often necessary to trim 5′ displaced strands to enable joining of the newly polymerized strand to the adjacent 3′ sequence.", "This repair process requires two enzymes and three enzymatic activities.", "DNA polymerase holoenzymes like E. coli DNA polymerase or Bst DNA polymerase possess two of these activities, a 5′ to 3′ endonuclease activity that removes these 5′ displaced flaps and, of course, DNA polymerase activity.", "In particular embodiments, Bst polymerase is preferred because it also lacks 3′ to 5′ nuclease activity that is often associated with DNA polymerase holoenzymes.", "See, e.g., FIG.", "31.This feature is useful because it suggests that the single-stranded 3′ DNA protrusions of the target genomic clones do not require protection.", "The other enzyme and activity required is a nick-closing DNA ligase such as the NAD+-requiring Taq DNA ligase.", "Following processing, processed fragments are amplified by PCR to allow for size selection and quantification prior to sequencing.", "Proof of Principle Oligonucleotides: For this experiment, eight target regions were chosen that correspond to eight genomic regions for which we have qPCR assays.", "The forward and reverse primers for these eight regions are shown in Table

pool and 10 μL of 100 uM common, biotinylated partner oligo were combined in 605 μL of TEzero+0.05% Tween 20 (TT).", "The 100× stock was further diluted 100-fold (10 μL into 990 μL TT) to give a working solution in which each probe is present at a concentration of 1 nM.", "Capture/Processing Protocols: One objective of the proof of principle study was to validate probe performance and test the efficiency of processing on sequence-ready library yield.", "The genomic library pool was derived from a 16 sample set library.", "For probe annealing, four of 10 μL library aliquots in separate PCR strip tubes were heated to 98° C. for 2 min and cooled on ice.", "Five μL of 4× bind buffer and five μL of probe were added to each tube, and the solution was annealed using a 1° C. step for four min thermal cycler program from 98° C. to 69° C. Annealed complexes were bound to streptavidin-coated magnetic beads, washed four times with 25% formamide-containing wash buffer and one time with TEzero.", "The final complexes were suspended in 2 μL of TEzero.", "Four treatments of the four complexes were investigated: (1) No processing, amplification with ACA2 primer alone to determine raw capture efficiency; (2) No processing, amplification with AF and CR to determine unprocessed amplification and capture efficiency; (3) PreCR processing in 10 μL prior to AF and CR amplification to explore low volume processing; and (4) PreCR processing in 50 μL prior to AF and CR amplification to establish high volume processing effects.", "PreCR processing was accomplished by adding the manufacturer's recommended solution that contained per 100 μL: 82 μL of water 10 μL of Thermopol buffer 1 μL of 100×NAD+ 1 μL of 10 mM dNTPs 2 μL of PreCR enzyme mix Ten μL of PreCR cocktail was added to tube 3 and 50 μL was added to tube 4.These were incubated

of Assay primer (10 uM in both F and R primer) was added.", "This was distributed in columns.", "Two μL of sample was added in rows and the plate was cycled as described above.", "Results: Amplification of Complexes: While the fluorescence profile of amplifying complexes is used primarily to identify the amplification plateau (which occurs much sooner for single primer than dual primer amplicons), the Cq value can be used to look at the content of amplicon between samples.", "In this experiment, the observed Cq values were: Sample Conditions Cq 1 no PreCR, ACA2 single primer 15 2 no PreCR, AF + CR 21 3 10 μL PreCR, AF + CR 20 4 50 μL PreCR, AF + CR 19 These data demonstrated that PreCR treatment increased the abundance of P1+P2 (AF+CR) amplicons.", "Gel images of the post-processing PCR products shown in FIG.", "33 show that PreCR treatment supported the amplification of a larger size distribution of clones.", "The untreated, sample 2 amplicon is primarily a cluster of small size fragments.", "Sample 3 and to a greater extent sample 4 are more broadly distributed smears.", "The qPCR results showing target enrichment are shown in Table 31 below.", "The raw sequence capture in sample 1 was surprisingly high.", "At least two factors may have contributed to such an unexpected improvement over historical data sets: (1) The core annealing process (pre-melt, higher temps, low salt binding to strep beads) has been optimized; and (2) A longer partner oligo (40 nt vs 35 nt) was used.", "Even with no PreCR treatment, P1+P2 (AF+CR) amplifiable material was made (sample 2) and substantial enrichment of target signal over gDNA (and/or NTC) was observed.", "PreCR treated complex also yielded enrichment levels comparable to unprocessed (sample 1) control.", "This is a fantastic demonstration of the fact that PreCR processing can stimulate the recombination of the probe-based partner oligo with the genomic library-based target clones.", "While the levels of enrichment are not remarkable, the majority of clone material is small and falls outside the range of the qPCR assay.", "As noted elsewhere herein, judicious bead enrichment can dramatically increase the proportion of the library that covers the qPCR site.", "In addition, the results indicated that more PreCR is not necessarily better.", "Sample 3 (10 μL PreCR treatment) outperformed

PEG8000—a molecular crowding agent.", "In addition, it was found that suppression PCR just upstream of sequence library construction is a powerful method to enrich for long insert sequencing clones.", "Background: The molecular concepts behind library-free methods include: (1) fragmenting gDNA to ˜400 bp or performing 1st strand cDNA synthesis with random 15-mers in the presence of ddNTPs (FIG.", "33); (2) melting the gDNA or cDNA with labeled capture probes and purify the end-repaired gDNA/cDNA.", "For gDNA, the genomic sequence is repaired with a sequence tag that comprises a random hexamer

appears at 16 cycles.", "These data together with the qPCR from the initial investigation support the interpretation that T4 DNA polymerase in conjunction with T4 gene 32 protein in the presence of the molecular crowding agent PEG8000 (the latter contribution has not been evaluated) is capable of efficiently copying captured genomic material onto capture probes.", "Methods, Results and Discussion: Part III—Generation of a Library-Free Sequencing Library: The methods described above were used to produce a DNA sequencing library with the four Coriel samples shown in the “Materials”

KRAS relative to MYC are no longer comparable).", "However, relative copy number (the change of PLP1 relative to the autosomal normalizers) is robustly detected.", "The sequencing results also showed striking features related to read start sites relative to probe.", "FIG.", "45 shows that reads are detected as far as 900 bp from the probe; and between coordinates 1100 and 1300 every single start point is used multiple times.", "These data indicated that reads start at every single possible base position and that there is little ligation/processing bias.", "In addition, there are very few reads that start within 100 bp of the probe, consistent with the very large size distribution of the library that was observed on gels.", "Example 21: Targeted Gene Expression Analysis Overview: This example demonstrates the development of targeted gene expression libraries.", "The input is RNA, not DNA, and therefore double-strand cDNA synthesis step is required.", "A preferred method is 1st strand synthesis using an RNAse H− reverse transcriptase or a kit that exhibits RNAse H-like activity (e.g., Promega's GoScript) and priming with random hexamers.", "A preferred method for 2nd strand synthesis is to use a kit that includes E. coli DNA polymerase holoenzyme, NAD+-dependent ligase and RNAse H (e.g., New England Biolabs 2nd strand cDNA synthesis module).", "Because there is a very wide range of transcript copies, there must be a correspondingly wide range of random tags that are introduced on adaptors to sheared and end-repaired cDNA.", "Accordingly, random 8-mers (65,536 possible sequences) were used.", "The adaptor was engineered with a random 8-mer sequence followed by 10-12 fixed bases that can both serve as an annealing site for a complementary 10-12 that facilitates ligation and that is used as a sample identifier in the case of multiplexed samples.", "The actual number of unique versus duplicated reads—in other words the statistical distribution of reads—is one important factor in determining expression levels.", "One potential source of error are reads that are duplicated after the capture event.", "To identify these errors, a random tag was added to the capture probe such that each capture event is labeled.", "The treatment and sequencing of targeted RNA-seq libraries follows the same procedure as treatment of genomic libraries.", "The informatics analysis starts with the removal of post-capture duplicate reads and alignment to the target transcriptome.", "The unique read counts among aligning reads are then determined.", "While the data can then be fit to a statistical distribution, it was found that the raw unique read counts are a very close approximation to actual expression levels.", "Purpose: The purpose of these experiments was to make targeted expression sequencing libraries from heart and liver total RNAs and to make both total RNA and targeted RNA libraries from the same starting material a direct comparison could be made.", "Summary: The RNA counts from total RNA libraries and from targeted RNA libraries showed good agreement along two parameters.", "First, the expression ratios between heart vs liver samples were well correlated.", "Second, the measurement of absolute abundance of different transcripts within a given sample was in good agreement when total RNA counts were compared to targeted RNA counts.", "These first-pass data indicated that quantitative targeted nucleic acid methods can be extended beyond genomic DNA into the analysis of cDNA libraries.", "Strategy: To create a reasonable total RNA library that is depleted of rRNA, dT priming was used.", "To create targeted RNA libraries, total RNA samples were initially primed with IDT-supplied random hexamers.", "Random hexamer priming likely provides the most comprehensive coverage of the transcriptome.", "The total RNA libraries were sequenced after amplification with PCR primers that introduce P1 and P2 flow cell sequences.", "For targeted analysis, the capture, washing, processing and amplification steps were performed as contemplated elsewhere herein.", "The targeted clones were then sequenced.", "Methods Oligonucleotides: For total RNA libraries the poly-dT primer: TTTTTTTTTTTTTTTTTTVN (SEQ ID NO: 722) was used.", "For targeted RNA-seq, an adaptor design was created in which the first 8 bases were

be used in medical imaging, e.g.", "in extraoral dental imaging.", "The unit 200 includes a rotating part (gantry) 220, which includes an X-ray unit which includes a first X-ray source 224.An X-ray imaging detector unit (head) 226 is attached to the rotating part 220.A position of the detector unit 226 can be adjustable, e.g.", "the detector unit 266 is rotable or movable in a linear fashion.", "The X-ray source 224 and/or the detector unit 226 provides e.g.", "a Panoramic, CT, or Cephalometric image by means of at least a rotational movement R around a rotation axis 222 of the rotating part 220.The R-movement of the rotating part 220 is e.g., up to 400 degrees around the rotation axis 222.The rotating part 220 includes a rotating motor, which is configured to rotate the rotating part 220 by means of rotation means (not shown).", "Alternatively, the rotating motor can be in an upper shelf 250 of the unit 200.The rotating part 220 has e.g.", "a form approximating a letter C and the X-ray source 224 is on one end of the rotating part 220.The X-ray source 224 is common for two imaging modes—the Panoramic imaging and CT imaging, e.g.", "the CBCT imaging, where an X-ray beam is a cone-shaped beam.", "In additional CT imaging techniques, the X-ray beam can be a pyramidal-shaped beam, half-moon -shaped cone beam, or other shaped beam.", "In addition, the X-ray source unit includes a beam limiting device 228 for the X-ray source 224 and a beam limiting motor configured to adjust the device 228.During imaging the beam limiting device 228 controls the size and shape of the X-ray beam so that it matches the needs of a selected imaging protocol, selected image size, and related detector size.", "On the other end of the rotating part 220 is the detector unit 226, which can include e.g.", "one or two X-ray detectors 227a, 227b (see FIGS.", "2f-2h).", "An exemplary embodiment of a one-detector X-ray unit 226 can include one X-ray detector 227 which may include one Panoramic detector, one Cephalometric detector, which enables also the Panoramic imaging, one Panoramic/CT combination detector, one Panoramic/CT/Cephalometric combination detector, or one detector configured to be used in Panoramic/CT imaging and in one-shot Cephalometric imaging.", "The one detector X-ray detector unit can be adjustable, e.g.", "by rotating the detector unit 226 relative to the rotating part 220 so that the one detector of the detector unit 226 can he positioned preferably perpendicularly to the used X-ray source 224 or 265 (described in further detail herein) and/or by moving one detector or detector unit 226 in a linear fashion relative to the rotating part 220 for adjusting a distance between the one detector or detector unit 226 and the X-ray source 224 in Panoramic/CT imaging.", "In an exemplary embodiment of a two-detector X-ray detector unit 226, the detector unit 226 can include one Panoramic detector and one CT detector 227b, or one Cephalometric detector 227a, which enables also the Panoramic imaging, and the CI detector 2271).", "In a two-detector embodiment of the detector unit 226, the detectors are arranged e.g.", "successively in Panoramic imaging, whereupon the Panoramic or Cephalometric detector 227a is arranged as a front detector for arranging magnification ratio for the imaging mode, and the CT detector 227b as a rear detector.", "The swap of the detectors 227a, 227b is arranged so that the front detector 227a moves aside by means of moving means 230, e.g.", "a rail 231a, 231 b and a rotator configured to move along the rail 231a, 231b and to rotate so that the front detector 227a slides e.g.", "next to a rear detector 227h, when it is necessary to use the rear detector 227a in CT imaging or the front detector 227a in Cephalometric imaging, Alternatively, the front detector 227a can be moved to another position relative to the rear detector 227b in Cephalometric imaging.", "The place of the front detector 227a in Cephalometric imaging may depend upon on how the front detector 227a is displaced by means of the swap movement, and the R- and L-, movements relative to the used X-ray source 265.The Cephalometric detector 227a can he positioned preferably perpendicularly to the used X-ray source 265.The front detector 227a returns similarly by sliding, when it is necessary to move the front detector 227a back to the front position.", "The rotating part 220 can comprise a detector motor 235 configured to move at least one detector by means of the moving means 230, if the detector unit 226 includes separate detectors 227a, 227b for the Panoramic and CT imaging.", "In addition, the unit 200 includes a column 240 for adapting a height Z of the unit 200—and the rotating part 220.The column 240 comprises height adapting means 241 which may include e.g.", "a height motor, a gear, and a threaded rod, and telescopic or counter weighted means configured to be driven by the height motor, for providing an up/down movement Z to adapt the height of the rotating part 220 to the height of the patient 201 for the Panoramic, Cephalometric, or CT imaging modes.", "The height adapting means 241 can realize the Z-movement e.g.", "as a movement of the height adapting means and/or as a telescopic or counterweighted movement.", "A lower shelf 242 is attached to the column 240 and the rotating part 220 is configured to be positioned over the lower shelf 242 during the Panoramic and CT imaging.", "The lower shelf 242 is used for positioning a patient 201 for the Panoramic and/or CT imaging and for supporting the patient 201 e.g.", "from a tip of the patient's 201 chin during the imaging.", "Alternatively, when the unit 200 includes a seated patient's 201 positioning system (not shown), the Z-movement is realized e.g.", "by adapting in the Z-direction the height of at least one of the following: a chair, the lower shelf 242, and the column 240.The lower shelf 242 can also include a head support (not shown), which supports e.g.", "the patient's 201 forehead and/or temple in the Panoramic/CT imaging position.", "The unit 200 includes said upper shelf 250, which supports the rotating part 220.The upper shelf 250 is attached to e.g.", "an upper end of the column 240 with a pivoting joint (means) 252, which enables a pivot movement P of the upper shelf 250 around the column 240 and in respect'to a lower shelf 242 so that the rotating part 220 is over e.g.", "the lower shelf 242.The upper shelf 250 includes pivot movement means 253, which includes e.g.", "a pivot motor 253 configured to pivot the upper shelf 250 around the column 240 by means of the pivoting joint 252.The upper shelf 250 includes linear movement means 223, e.g.", "a linear conveyor configured to support the rotation means of the rotating part 220 and to enable the rotating part 220 to rotate around the rotation axis 222, at least one rail and/or track configured to guide the linear conveyor in the upper shelf 250, and a linear motor configured to drive the linear conveyor along the at least one rail and the upper shelf 250, which enable the rotating part 220 and the rotation means to move with respect to the upper shelf 250 by means of a linear movement L. The linear movement means 223 of the upper shelf 250 can be provided so that L movement in a plane of the upper shelf 250 is a direct linear movement, e.g.", "it is parallel to the upper shelf 250 or it is in a certain angle with respect to the parallel direction, or the L-movement in the plane of the upper shelf 250 is a non-direct linear movement having e.g.", "a curved path or a devious path.", "The rotation means attach the rotating part 220 to the upper shelf 250.The rotation means are able to move with at least one L-movement so that the axis 222 and, thus, the rotation center in respect to the upper shelf 250 can be adjusted along the L-movement.", "Thus, the axis 222 can be positioned within a plane defined by the P-movement of the upper shelf 250 and the L-movement of the rotating part 220 during the imaging.", "By using a rotating P-movement, rather than a linear X-movement, to adjust the lateral position of the rotating axis 220, it is possible to design much lighter and thinner upper shelf 250, thus giving the unit 200 a smaller footprint.", "In contrast, the conventional method of relying on a linear X-movement requires a wider upper shelf 250, and relying on an NP-movement requires a wider rotation part 220, as depicted in FIG.", "1b.", "The X-ray source 224 on the one end of the rotating part 220 typically weighs more than the detector unit 226 on the other end, As a result, a movement of the center of the gravity of the rotating part 220 can cause a varying load to a joint construction (not shown) of the rotating part 220, which includes the linear movement means 223, so that the rotating part 220 wobbles during the imaging and, thus, reduces the image quality.", "In order to eliminate these problems, the upper shelf 250 includes a controlling arrangement (not shown) that enables the R-movement of the rotating part 220 in relation to the upper shelf 250 so that the axis 222 travels substantially with the center of the gravity of the rotating part 220, which, in turn, stays in a neutral axis of the joint construction of the rotating part 220 during the imaging.", "A virtual rotation axis of the rotating part 220 is achieved by synchronizing R-, L-, and P-movements during the scanning.", "The controlling arrangement, by operating the rotating part 220 in the manner described above, removes any torque applied to the joint construction and increases an image quality by removing artifacts caused by wobbling.", "In addition, the controlling arrangement enables to produce a lighter, cheaper, and slender structure of the rotating part 220 and its joint construction In addition, the unit 200 includes on one side of the column 240 a first Cephalometric arm 260 that has a certain first length.", "The arm 260 attaches a Cephalometric head (unit) 262 to the unit 200 at a certain first distance that corresponds with the first length from the column 240.The Cephalometric head (support) 262, which has a significantly simpler structure than in traditional Cephalometric units, includes Cephalometric patient support means 268, 269, e.g.", "two ear rods 268 and a nose (nasion) support 269, for supporting the patient 201 to be imaged.", "The patient's 201 head is supported e.g.", "from an outer part of the ear canal with the ear rods 268 and from the nose using the nose support 269.The ear rods 268 and nose support 269 can be attached to the Cephalometric head 262 in a manner that enables them to rotate e.g.", "to two main imaging positions: lateral and PA projections.", "The lateral projection is basically a side view and the PA projection is from back to front view of a skull of the patient 201.The ear rods 268 can be tiltable or rotable ear rods having a down position, where the ear rods 268 support the patient 201, and an up position, where it is possible to place the patient 201 in the Cephalometric imaging position or where the patient 201 can depart from the Cephalometric imaging position, when the tilted or rotated ear rods 268 in the up position provide a clear passage of the patient 201.In addition, the unit 200 may include on other side of the column 240 a second Cephalometric arm 261 that has a certain second length.", "Attached to the second Cephalometric arm 261 is a second X-ray source 265, which is used in Cephalometric imaging.", "The second Cephalometric arm holds the second x-ray source at a second distance from the unit 200, corresponding to a second length from the column 240.The X-ray source 265 includes a beam limiting device 267 for the Cephalometric imaging.", "Optionally, the beam limiting device 267 can be attached to the X-ray source 265.The X-ray source 265 can be configured to rotate around a rotation axis 264 by means of rotation means 263 configured to perform a scanning movement S. The axis 264 of the X-ray source 265 is in line with a focal spot of the X-ray source 265 so that it passes through the focal spot.", "The arm 261 or the X-ray source 265 includes a rotating motor, which is configured to rotate the X-ray source 265 around the axis 264, which coincides with the focal spot of the X-ray source 265.The arms 260, 261 can be separate arms attached to the column 240, or it is possible to use one arm 260, 261, which includes the Cephalometric head 262 in its one end and the X-ray source 265 with the beam limiting device 267 in the other end of the single arm 260, 261.FIG.", "2d illustrates how the Cephalometric, combination, or one-shot detector of the detector unit 226 attached to the rotating part 220 can be used to perform Cephalometric imaging.", "In addition, FIG.", "2d shows that the rotating pan 220 can include a Cephalometric (secondary) collimator 266, which is used in the Cephalometric imaging together with one detector of the detector unit 226.The Cephalometric collimator 266 is attached, e.g., to one (right) side of the rotating pan 220 (e.g.", "X-ray source 224), as depicted in FIG.", "2c.", "Alternatively, the Cephalometric collimator can be attached e.g.", "to another (left) side of the rotating part 220 (e.g.", "X-ray source 224).", "In addition, the rotating part 220 can include a detector motor 235 configured to rotate at least one detector of the detector unit 226 for the Cephalometric imaging, and a collimator motor configured to adjust a position (height) of the Cephalometric collimator 266 in the Z-direction and/or a position of the collimator of the X-ray source 224.Alternatively, or in addition, the beam limiting motor or the collimator motor can he configured to adjust both the device 228 and the Cephalometric collimator 266.The rotating part 220 is driven over the Cephalometric head (support) 262, e.g.", "with the P-, R-, and L-movements, so that the detector unit 226 and the Cephalometric collimator 266 are positioned for the Cephalometric imaging.", "The X-ray source 265 can be configured to provide, together with e.g., the detector unit 226 (e.g.", "the Cephalometric detector 227a attached to the detector unit 226) and the Cephalometric collimator 266 in the rotating part 220, a Cephalometric image from the positioned patient 201, when it is rotated around the axis 264 by means of the S-movement, and the detector unit 226 and the Cephalometric collimator 266 are arranged to move e.g.", "by means of at least one of the P-, R-, and L-movements of the rotating part 220.Alternatively, the scanning movement of the x-ray beam—e.g.", "a linear S-movement—can be performed by moving the beam limiting device 267 of the X-ray source 265.If the one-shot detector is used, the detector unit 226 and the Cephalometric collimator 266 are positioned by means of at least one of the P-, R-, and L-movements, but the image can be taken without these movements and/or without the S-movement.", "Thus, there is no need for a dedicated holder or the Cs-movement for the detector unit 164 and the Cd-movement of the Cephalometric collimator 166, when the scanning movement is executed with e.g.", "the P-, R-, L-, and S-movements.", "The arms 260, 261 can be arranged so that a height of the Cephalometric head 262 with the ear rods 268 and nose support 269 is fixed relative to the X-ray source 265.However, the fixed height may cause problems, because an anatomy of patients 201 varies—e.g., the vertical distance where ear openings are located compared to patient's 201 shoulders differs significantly from one patient 201 to another.", "Thus, either the patient 201 is located too low in the resultant Cephalometric image, showing only upper vertebras, or the patient 201 is located so high in the images that the shoulder of the patient 201 touches the detector unit 226, which is a problem especially with a scanning.", "Furthermore, the preferred Cephalometric imaging geometry requires that the focal spot and the tips of the ear rods 268 are at the same (horizontal) axis.", "In order to eliminate these problems, variable length ear rods 268 can be used while keeping the arms 260, 261 fixed height relative to each other.", "Alternatively or in addition, in order to eliminate these problems, the unit 200 can comprise Cephalometric height adjusting means (not shown) that are configured to independently adjust the height—in respect to the column 240—of the arms 260, 261 that support the Cephalometric head 262 at the one end and the X-ray source 265 on the other end.", "When the operator has adjusted the height of the arms 260, 261 by means of an up/down Zc-movement, the focal spot follows the tips of the ear rods 268 automatically and, thus, the geometry (ear rod tip to focal spot line) remains intact.", "Yet, the detector unit 226 and the Cephalometric collimator 266 on each side of the patient 201 take their height from the column 240 and, thus, are on a different height in respect to the ear rods 268 and the patient 201 than before the adjustment.", "The Cephalometric height adjusting means provides a way to adapt an exposed area to a given anatomy of the patient 201 by enabling an operator (user) to adjust the height of the patient 201 without compromising the geometry.", "Since the first and second X-ray sources 224, 265 can be arranged at different heights with respect to the column 240 in the Z direction by means of the height adapting means 241 and/or the Cephalometric height adjusting means, it is possible to position the patient 201 without any additional adjustment of the Cephalometric head 262 in the Z direction as it is needed when using the X-ray source 224 of the rotating part 220 for the Cephalometric imaging.", "The movements of unit 200 are simple, because the traditional X-movement, as well as the Cd- and Cs-movements of the detector unit 226 and the secondary collimator 266 in the Cephalometric head 262, are replaced by using the P-movement instead.", "The movements are carried out using the L-movement and the P-movement of the upper shelf 250.In addition, by using the P-movement, the structure of unit 200 is made simpler and cheaper, because the Cephalometric imaging can optionally be implemented by using only one “non-detachable” detector unit 226.This reduces the risk of breaking the detector unit 226 because there is no need to remove it from a holder of the rotating part 220 to detach it from a holder of the Cephalometric head 262 when changing the imaging mode from the Panoramic/CT mode to the Cephalometric mode.", "The detector for the Panoramic imaging in the detector unit 226 can be rotated from the Panoramic imaging position to the Cephalometric imaging position so that it is possible to use the same detector in both Panoramic and Cephalometric imaging.", "In addition, the structure of unit 200 provides a simple workflow

cancer deaths in the western population, following lung cancer (Landis et al., 1998, CA Cancer J.

blot analysis showed that PCA3 is highly expressed in the vast majority of prostate cancers examined (47 out of 50) whereas no or very low expression is detected in benign prostate hyperplasia or normal prostate cells from the same patients.", "There is at least 20-fold overexpression of PCA3 in prostatic carcinomas in comparison to normal or BPH tissues.", "PCA3 expression seems to increase with tumor grade and is detected in metastatic lesions.", "In summary, prostate cancer staging based on specific markers such as PSA and PSM is a very promising avenue for the management of the disease.", "The drawback of using PSA or PSM for prostate cancer staging is that they are expressed in normal as well as in cancerous cells.", "In addition, poorly differentiated tumors may escape diagnosis since they tend to produce significantly less PSA protein than less aggressive tumors.", "This is the case for 10% of all prostate cancers.", "PCA3, on the other hand, is differentially expressed in cancerous and normal prostate cells, and its expression does not decrease with increasing tumor grade.", "PCA3 could therefore be a useful tool which may overcome the drawbacks of PSA and PSM in the diagnosis, staging and treatment of prostate cancer patients.", "The present description refers to a number of documents, the content of which is herein incorporated by reference, in their entirety.", "SUMMARY OF THE INVENTION The invention concerns the discovery of distinct PCA3 RNAs associated with a non-malignant and/or malignant status of the prostate.", "The invention also concerns

molecule having an additional sequence of 228 bp (shown in SEQ ID NO:1), inserted between exons 3 and 4a, whereas the other lacks the additional sequence (SEQ ID NO:2).", "The RNA lacking the additional sequence is associated with prostate cancer whereas the RNA comprising same is associated with a non-malignant prostatic state.", "Based on the differential expression of these two PCA3 RNA species, protocols for the diagnosis of prostate disease are provided.", "The above findings could also lead to a therapeutic approach to prostate cancer.", "The invention further concerns reagents and methods to assess the prostate status in an animal, comprising a quantitative determination of SEQ ID NO:1 or fragments, or variants thereof with respect to SEQ ID NO:2 or fragments, or variants thereof.", "Thus, the present invention relates to the discovery and characterization of a novel sequence expressed in PCA3 mRNA, which enables a determination of the prostate status of an animal, based on a determination of the relative abundance of two differentially expressed PCA3 mRNAs.", "The invention provides, in general, isolated nucleic acid molecules encoding differentially expressed

sequence between exon 3 and exon 4a.", "In a particularly preferred embodiment, this additional sequence comprises the sequence of SEQ ID NO:1, variants of parts thereof.", "The invention also relates to an antibody having binding affinity specifically to a polypeptide encoded by a differentially expressed PCA3 mRNA or an epitope-bearing portion thereof.", "The invention further provides a method of detecting differentially expressed PCA3 mRNAs in a sample.", "As well, it also provides a method of measuring the amount of differentially expressed PCA3 mRNAs in a sample.", "The invention further

develop prostate cancer in a patient is provided herein.", "The invention also provides methods for therapeutic uses involving all or part of (1) a nucleic acid sequence encoding the differentially expressed PCA3 mRNAs, variants or parts thereof, (2) antisense to differentially expressed PCA3 mRNA molecules, variants or parts thereof, (3) protein encoded by a differentially expressed PCA3 mRNA, variants or parts thereof, or (4) antibodies to proteins encoded by differentially expressed PCA3 mRNAs.", "Further, the invention provides a method to modulate the level of differentially expressed of a first PCA3 mRNA (e.g.", "the long one) and a second PCA3 mRNA (e.g.", "the short one) by expressing one of the first or second differentially expressed mRNA.", "In a preferred embodiment, the invention provides a modulation of the differentially expressed PCA3 mRNAs such that the level of the first PCA3 mRNA is superior to that of the second.", "Having identified the differential expression of mRNAs as a marker for prostatic state of an animal, and more particularly having shown that the presence of the additional sequence, which interrupts the coding sequence of the PCA3 encoded protein, correlates with a non-malignant state, while the absence of the additional sequence and a non-interruption of the thereby encoded protein, correlates with malignant cancer, the present invention therefore provides the means to interrupt the coding sequence of the PCA3 protein, using any means of genetic engineering, known to a skilled artisan, and assesses whether such an interruption can revert the malignant phenotype.", "In order to provide a clear and consistent understanding of terms used in the present description, a number of definitions are provided

ILLUSTRATIVE EMBODIMENTS In one embodiment, the present invention relates to an isolated and/or purified differentially-expressed PCA3 mRNA molecule.", "Preferably, the PCA3 mRNA or nucleic acid molecule comprises a polynucleotide sequence at least 90% identical (more preferably, 95%, 96%, 97%, 98%, 99% or 100% identical) to a sequence selected from the group consisting of: (a) a nucleotide sequence encoding a differentially expressed PCA3 polypeptide comprising the complete amino acid sequence in SEQ ID NO: 3; (b) a nucleotide sequence complementary to any of the nucleotide sequences in (a) or (b).", "In another embodiment, the isolated nucleic acid molecule comprises a differentially expressed PCA3 mRNA nucleotide sequence with greater than 90% identity or similarity to the nucleotide sequence present in SEQ ID NO: 1 (preferably greater than 95%, 96%, 97%, 98%, 99% or 100%).", "In another preferred embodiment, the isolated nucleic acid molecule comprises the differentially expressed PCA3 mRNA sequence lacking the additional sequence present in SEQ ID NO:2.In another embodiment, the isolated differentially expressed additional sequence-minus mRNA sequence nucleic acid molecule encodes the differentially expressed PCA3 amino acid sequence present in SEQ ID NO:3.Although PCT application CA98/00346 teaches a number of alternatively spliced mRNAs, prior to the present invention, a PCA3 mRNA comprising an additional sequence between exon 3 and exon 4a had not been identified.", "Furthermore, the identification of this additional sequence as a distinguishing marker of the prostate state had not been made.", "In addition, the correlation between the PCA3 mRNA minus the additional sequence and prostate cancer (as opposed to the PCA3 mRNA-containing the additional sequence in non-prostate cancer [i.e., normal or BPH]) had not been made.", "Thus, the additional sequence in PCA3 mRNA enables a prognosis and diagnosis of prostatic diseases in a patient.", "Preferably, the PCA3 nucleic acid molecule comprises a polynucleotide sequence at least 90% identical (more preferably, 95%, 96%, 97%, 98%, 99% or 100% identical) to one of

nucleotide coding sequence and fragments thereof permitted by the genetic code are, therefore, included in this invention.", "Further, it is possible to delete codons or to substitute one or more codons by codons other than degenerate codons to produce a structurally modified polypeptide, but one which has substantially the same utility or activity of the polypeptide produced by the unmodified nucleic acid molecule.", "As recognized in the art, the two polypeptides are functionally equivalent, as are the two nucleic acid molecules which give rise to their production, even though the differences between the nucleic acid molecules are not related to degeneracy of the genetic code.", "One skilled in the art will realize that genomes often contain slight allelic variations between individuals.", "Therefore, the isolated nucleic acid molecule is also intended to include allelic variations, so long as the sequence is a functional derivative of the differentially expressed PCA3 mRNA coding sequence.", "When a PCA3 allele does not encode the identical sequence to that found in SEQ ID Nos:1 or 2, it can be isolated and identified as PCA3 using the same techniques used herein,

less than a predetermined value (for example, five (cells)).", "This predetermined value may be set in advance, or may be configured semi-statically or dynamically between radio base stations eNB and

configured may be reported to the radio base stations eNB in the form of user terminal capability information (UE capability information).", "In dual connectivity, as noted earlier, significant backhaul delays may be produced between eNBs.", "Consequently, in order to allow each eNB to transmit and receive control information to and from UEs independently, even an SeNB requires a cell (also

"Furthermore, to bring the above-noted conception into practice, the present inventors have focused on the fact that, when dual connectivity is not employed, the maximum transmission power per serving

PCMAX_MeNB,c, between the upper limit and the lower limit calculated based on equations 3 and 4.Also, the user terminal calculates the maximum transmission power per serving cell formed by the SeNB, PCMAX_SeNB,c, between the upper limit and the lower limit calculated based on equations 5 and 6.Note that, although, in equation 4 and equation 6, ΔTC,c is subtracted from both QEMAX_MeNB,c and

per eNB—PCMAX_MeNB_H, PCMAX_MeNB_L, PCMAX_SeNB_H and PCMAX_SeNB_L—can be represented as shown by equations 9 to 12, respectively: PCMAX_MeNB_H=MIN{PMeNB,10 log10ΣpEMAX,c,PPowerClass} (Equation 9)

serving cells belonging to the SeNB/SCG in the event of equations 11 and 12.Also, PMeNB and PSeNB are the linear values of PMeNB and PSeNB, respectively.", "The user terminal sets the maximum transmission power per MeNB, PCMAX_MeNB between the upper limit and the lower limit based on equations 9 and 10.Also, the user terminal sets the maximum transmission power per SeNB, PCMAX_SeNB between the upper limit and the lower limit calculated based on equations 11 and 12.By this means, as shown in FIG.", "4, it is possible to set the maximum transmission power per MeNB (PCMAX_MeNB) and the maximum transmission power per SeNB (PCMAX_SeNB) within the maximum transmission power per UE (PCMAX).", "Note that no problem arises even when 10 log10ΣpMeNB/ΔtC,c and 10 log10ΣpSeNB/ΔtC,c in

a user terminal can determine the maximum transmission power of each eNB by using equations 7 and 8.When PeNB is not signaled in a specific eNB, the maximum transmission power for this eNB is set using equations 7 and 8.As described above, according to the second embodiment, the maximum transmission power PeNB of each eNB can be controlled flexibly, on a per user terminal basis, so that, even in dual connectivity, it is possible to change the ratio of power to allocate to each eNB flexibly, and reduce the decrease of uplink throughput.", "Also, given that few changes are made to the existing rule of determining PCMAX,c, there is little impact on the implementation of user terminals.", "Third Embodiment As described above, to divide transmission power completely between an MeNB/MCG and an SeNB/SCG, it is necessary to make sure that the maximum value of the maximum transmission power of both eNBs/CGs—that is, the sum of PCMAX_eNB_H and/or the sum of PCMAX_eNB_H,c—does not exceed PCMAX.", "However, the actual maximum transmission power is set by user terminals from the configuration range.", "Consequently, in both eNBs/CGs, there is little likelihood that power is used up to PCMAX_eNB_H and/or PCMAX_eNB_H,c.", "In this way, setting the maximum transmission power in each eNB/CG separately may have the risk that power is not allocated efficiently.", "Now, this problem will be described in detail with reference to FIG.", "6.FIG.", "6 is a diagram to show an example of uplink transmission power that can be allocated in a user terminal.", "In FIG.", "6, PCMAX_MeNB_H, PCMAX_MeNB_L, PCMAX_SeNB_H and PCMAX_SeNB_L are determined using the method described with the second embodiment, and PCMAX_MeNB and PCMAX_SeNB are set.", "In this case, power to match the proportion of (PCMAX_MeNB_H−PCMAX_MeNB) is not allocated to the MeNB, and power to match the proportion of (PCMAX_SeNB_H−PCMAX_SeNB) is not allocated to the SeNB, which has a threat of resulting in a decrease of uplink throughput.", "So, with a third embodiment of the present invention, in order to solve the above problem, instead of calculating the upper limit (PCMAX_eNB_H) of the maximum transmission power of each eNB individually, PCMAX_eNB for another eNB is set by calculating PCMAX_eNB_H for the other eNB by using PCMAX_eNB that is set with respect to a given eNB.", "To be more specific, based on PCMAX_eNB_H and PCMAX_eNB_L for one eNB, PCMAX_eNB for this eNB is determined.", "After that, the other eNB's PCMAX_eNB_H is set based on the difference between PCMAX and PCMAX_eNB that is determined first (PCMAX−PCMAX_eNB).", "FIGS.", "7 and 8 are each a diagram to explain a method of calculating the maximum transmission power per eNB/CG, according to the third embodiment of the present invention.", "In the examples of FIG.", "7 and FIG.", "8, PCMAX_SeNB is determined first, and PCMAX_MeNB is set.", "First, a user terminal determines PCMAX_SeNB based on PCMAX_SeNB and PCMAX_SeNB_L that are calculated using equations 11 and 12 (FIG.", "7).", "Next, the user terminal sees (PCMAX−PCMAX_SeNB) as PCMAX_MeNB_H, determines PCMAX_MeNB_L from this by taking into account the MPR and so on, and sets PCMAX_MeNB within the range of these (FIG.", "8).", "At this time, the user terminal may see PCMAX_MeNB_H as the maximum transmission power per MeNB PMeNB, and, for example, determine PCMAX_MeNB_L using equation 10.By this means, it is possible to reduce the useless space in power where the maximum transmission power is not set.", "FIG.", "6 makes it clear that the area where power is not allocated is smaller in FIG.", "8.When the maximum transmission power for the SeNB is determined first, the area of (PCMAX_SeNB_H−PCMAX_SeNB) can be re-used for power allocation, so that it is possible to use power efficiently.", "On the other hand, when the maximum transmission power for the MeNB is determined first, the area of (PCMAX_MeNB_H−PCMAX_MeNB) can be used to allocate power to the SeNB.", "As described above, according to the third embodiment, the user terminal does not determine the maximum transmission power of each eNB separately, but determines the maximum transmission power one by one.", "That is to say, once the maximum transmission power is determined with respect to a given eNB, the maximum transmission power in the rest of the eNBs can be determined within the range given by removing the maximum transmission power of the above given eNB from the maximum transmission power of the user terminal.", "By this means, the transmission power which the user terminal can use can be allocated to each eNB efficiently.", "Note that, although, in the above-described example, the third embodiment is applied to the method of calculating the maximum transmission power per eNB/CG according to the second embodiment, it is equally possible to, for example, apply the third embodiment to the method of calculating the maximum transmission power per cell according to the first embodiment.", "Furthermore, the order of determining the maximum transmission power per eNB in the third embodiment may be configured in user terminals in advance.", "For example, a stipulation to determine the maximum transmission power in the order of the SeNB and the MeNB may be set.", "Also, from the radio base stations, information regarding this order, information as to whether or not to determine the maximum transmission power of each radio base station separately and so on may be reported by higher layer signaling (for example, RRC signaling), by broadcast information, and so on.", "For example, information about the eNB where the maximum transmission power should be determined first may be included in the information elements to include terminal-specific information related to the maximum transmission power.", "(Variation) Note that the processes of setting the maximum transmission power, described with each of the above-described embodiments, can be applied even to cases where uplink signal transmission timings are not synchronized between a plurality of eNBs/CGs that are connected in dual connectivity (also referred to “as asynchronous dual connectivity”).", "Furthermore, in the maximum transmission power setting processes described with each of the above-described embodiments, the radio base stations require signaling for reporting specific information that relates to the maximum transmission power of uplink signals on a per user terminal basis, it is also possible to judge whether or not to report this signaling based on user terminal capability information (UE capability information).", "To be more specific, in systems in which dual connectivity is used, user terminal capability information may be stipulated as follows.", "For example, user terminal capability information to represent whether or not the maximum transmission power can be set on a per radio base station may be stipulated.", "Also, user terminal capability information to represent whether or not asynchronous dual connectivity can be supported may be stipulated.", "Furthermore, user terminal capability information to represent whether or not the transmission power of future transmission signals can be calculated in advance may be stipulated.", "In addition, user terminal capability information to represent whether or not transmission power can be shared between eNBs/CGs on a dynamic basis may be stipulated as well.", "The user terminal capability information may be reported from a user terminal to a radio base station in a stage before dual connectivity is configured.", "When, based on these pieces of user terminal capability information, the radio base station judges that the user terminal can perform the maximum transmission power setting processes according to the above embodiments, the radio base station may report user terminal-specific information.", "For example, when the radio base station judges that the user terminal cannot share transmission power on a dynamic basis between eNBs/CGs, in accordance with the above embodiments, the radio base station may distribute the maximum transmission power to the user terminal, semi-statically, on a per eNB/CG basis.", "(Structure of Radio Communication System) Now, a structure of a radio communication system according to an embodiment of the present

more of consumer accounts 131 to consumer 129, which can allow consumer 129 to know the amount of the available funds for spending before shopping for items and/or before attempting to purchase items.", "In a number of embodiments, account module 134 can provide account module 122 with various other information, such as the current status of one or more of consumer accounts 131, such as whether one or more of consumer accounts 131 is open and in good status (or closed), whether one or more of consumer accounts 131 has had recent not sufficient funds (NSF) activity, whether one or more of consumer accounts 131 has a stop payment order, and/or a buying power index of consumer 129 at least partially based on information about one or more of consumer accounts 131.In some embodiments, mobile application 123 can be used on mobile device 120 at point-of-sale terminal 110 to conduct a transaction.", "In several embodiments, mobile device 120 can receive the merchant identifier and other transaction information from point-of-sale terminal 110 of merchant 119.The merchant identifier can be associated with merchant account 151 of merchant 119.By receiving the merchant identifier, mobile application 123 can initiate a push payment from one or more of consumer accounts 131 at financial institution 130 to merchant account 151 at financial institution 150 to complete the transaction in real-time before the consumer leaves the store of merchant 119.In many embodiments, mobile device 120 can receive the merchant identifier and other transaction information from point-of-sale terminal 110 as part of the merchant security transaction code.", "In various embodiments, authentication module 121 can verify the identity of consumer 129.For example, authentication module 121 can verify the identity of consumer 129 using a personal identification number (PIN), a password, one or more fingerprints, voice recognition, other biometrics (e.g., mobile phone bio-measurements), and/or other suitable authentication methods, to ensure that consumer 129 is authorized to associate mobile application 123 with one or more of consumer accounts 131 and/or make payments using mobile application 123.In a number of embodiments, when mobile application 123 is used to conduct a transaction, mobile device 120 can be put in the proximity of point-of-sale terminal 110 to allow communication module 124 to receive information from point-of-sale terminal 110, such as the payment amount, the merchant identifier, a transaction identifier, and/or other information, such as the merchant name, the date and time, a list of SKUs (stock keeping units) of the one or more items to be purchased, etc.", "In many embodiments, mobile device 120 can receive the merchant identifier and other transaction information from point-of-sale terminal 110 as part of the merchant security transaction code.", "In several embodiments, security module 125 of mobile device 120 can verify the digital signature in the merchant security transaction code.", "For example, security module 125 can verify the digital signature using a signature verifying algorithm that is part of the same digital signature scheme that was used to digitally sign the merchant security transaction code.", "For example, a public key for merchant 119 can be used to verify the digital signature and the merchant security transaction code.", "By verifying the digital signature of the merchant security transaction code, security module 125 can verify that the merchant identifier is from point-of-sale terminal 110 of merchant 119 and is accurate, which can advantageously ensure that the funding from consumer accounts 131 will be sent to an account actually associated with the merchant instead of a fraudster.", "In some embodiments, mobile application 123 can be configured to allow one-click checkout, which can be enabled by selecting a button on mobile application 123 or by placing mobile device 120 in the proximity of a data transmitter on point-of-sale terminal 110.In some embodiments, mobile application 123 can be configured to scan items and conduct transactions in real-time as items are taken from the shelf and scanned by mobile device 120 or placed within a “smart” shopping cart, such that checkout can take place in an aisle of the store, rather than at point-of-sale terminal 110.In other embodiments, checkout can take place automatically when consumer 129 exits the store of merchant 119.In a number of embodiments, mobile application 123 can receive the merchant identifier upon entering the store of merchant 119 or from a shopping cart having data transmitted in the store of merchant 119.In some embodiments, the mobile application 123 can send information from mobile device 120 to point-of-sale terminal 110, such as information regarding consumer 129, such as personally identifiable information, loyalty rewards number(s), shopping patterns, points, buying power index, and/or other suitable information.", "In several embodiments, consumer information module 114 can process the information provided from mobile application 123 to provide information to merchant 119 regarding consumer 129.In some embodiments, mobile device 120 can communicate information, such as a buying power index, to point-of-sale terminal 110 and/or merchant 119 upon entering the store of merchant 119.In several embodiments, consumer 129 can decide whether to authorize the transaction using mobile device 120.For example, mobile device 120 can ask consumer 129 to approve the transaction in mobile application 123.In a number of embodiments, mobile application 123 can present the one or more of consumer accounts 131 to consumer 129 to select which of the consumer accounts 131 to use to funds the transaction.", "In some embodiments, consumer 129 can choose to split the funding of the transaction among multiple accounts.", "For example, consumer 129 can choose to fund 20% of the transaction from a demand deposit account (e.g., a debit account) and 80% of the transaction from a non-demand deposit account (e.g., by a charge to a credit account).", "In some embodiments, if an account of the one or more of consumer accounts 131 has an account balance that is less than the amount of the transaction (or the portion of the transaction that consumer 129 has chosen to allocate to the account), loan module 126 of mobile device 120 can determine that there is a deficiency and can present an option to fund the transaction (or a portion of the transaction) using a non-demand deposit account, such as a loan account, a credit account, or a points account.", "In other embodiments, loan module 126 can present the option for funding the transaction through a non-demand deposit account even if there is no deficiency in the one or more of consumer accounts 129.In some embodiments, the loan account can be a new account that is created upon consumer 129 choosing to fund the transaction (or portion thereof) with the loan account.", "In other embodiments, the loan account can be for a previously authorized loan.", "In some embodiments, the loan account can have a pre-existing loan balance, which can be increased based on the amount of loan used to the fund the transaction.", "In several embodiments, the loan can be a small loan, and can be labeled a “micro-loan”), but can be treated the same as credit line for a loan instead of an overdraw of an account.", "In several embodiments, consumer 129 can make the decision from which account or accounts to fund the transaction, and/or to authorize a loan or a credit transaction, while at or near the point-of-sale terminal 110 in the store of merchant 119.In the same or other embodiments, loan module 126 can allow consumer 129 to choose the one or more accounts from which to fund the transaction after consumer 129 has left the store.", "In many embodiments, financial institution 130 can fund the transaction temporarily from a shadow account that the bank uses to fund overdraft transaction, which can be reimbursed from the one or more accounts selected by consumer 129.For example, consumer 129 can authorize a transaction at point-of-sale terminal 110 in the store, and financial institution 130 can authorize transfer of funds to financial institution 150 to pay merchant 119, and after consumer 129 leaves the store of merchant 129, loan module 126 can push a message to consumer 129 asking for one or more of consumer accounts 131 that consumer 129 wants to use to fund the transaction.", "The options of consumer accounts 131 can include the option to open a new loan account, or to add to the balance of an existing loan account.", "In some embodiments, consumer 129 can setup a list (e.g., prioritized list) of consumer accounts 131 to use for transaction using mobile device 120, and/or can setup before-hand an amount and/or percentage to use from one or more of the accounts.", "For example, consumer 129 can choose to use a debit account for the first $50 and then use a credit account for the rest.", "As another example, consumer 129 can choose to use a debit account for 40% of the transaction, and use a new micro-loan for the rest.", "In some embodiments, a points account can be used to pay for all or at least a portion of the payment.", "For example, consumer 129 can have a points account at financial institution 130, which can have a balance of points earned by consumer 129 at financial institution 130.In many embodiments, these points can have an exchange value, such that the points can be redeemed to pay for all or at least a portion of the payment.", "In many embodiments, after mobile device 120 has communicated with point-of-sale terminal 110 using communication module 124 to receive the merchant identifier and other transaction information, and consumer 129 has authorized the transaction, mobile device 120 can communicate with financial institution 130 and/or transaction system 140, either directly or through mobile wallet provider 160, to request a payment be made to merchant account 151 of merchant 119 from one or more of consumer accounts 131.For example, when mobile device 120 communicates with financial institution 130 (either directly or through mobile wallet provider 160) to request a payment be made, account module 134 of financial institution 130 can determine account information about merchant account 151, such as the account identifier of merchant account 151, at least partially based on the merchant identifier received from mobile device 130.In some embodiments, financial institution 130 can communicate with transaction system 140 to get the account information about merchant account 151, which can be stored in merchant account database 141.In some embodiments, financial institution 130 can save the account information about merchant account 151 so financial institution does not need to query the account information from merchant account database 141 in transaction system 140 for future transaction involving the same merchant identifier.", "In other embodiments, financial institution 130 can query for the account information from merchant account database 141 in transaction system 140 for each new transaction, or at occasional and/or regular intervals.", "In other embodiments, when mobile device 120 communicates with transaction system 140 (either directly or through mobile wallet provider 160) to request a payment be made, transaction system 140 can provide the account information about merchant account 151 to first financial institution 130.In many embodiments, having the account information about merchant account 151, financial institution 130 can initiate a payment to financial institution 150 from one or more of consumer accounts 131 to merchant account 151.In several embodiments, before initiating payment, authorization module 133 can determine whether to authorize payment from one or more of consumer accounts 131.For example, financial institution 130 can determine whether the payment amount is within the available funds in one or more of consumer accounts 131, determine whether one or more of consumer accounts 131 is currently open and in good status (or closed), authenticate the identity of consumer 129 using mobile device 120, and/or perform other actions.", "For example, in some embodiments, authentication module 121 can authenticate the identity of consumer 129, and that information can be communicated from mobile device 120 to financial institution 130.In some embodiments, mobile device 120 can prompt consumer 129 to authenticate before and/or after mobile device 120 receives the merchant identifier and/or the transaction information from point-of-sale terminal 110.In some embodiments, authorization module 133 can request additional authentication from authentication module 121 (which can be directly through a network between financial institution 130 and mobile wallet 120, or can be through mobile wallet provider 160 and/or through transaction system 140) after receiving the request for payment from mobile device 120 and/or after receiving the information about merchant 119 and/or merchant account 151.In a number of embodiments, authorization module 133 of financial institution 130 can perform different and/or varying levels of authentication based on various factors.", "For example, authentication module 121 and/or authorization module 133 can determine whether mobile device 120 used to send the request for payment has been previously used by consumer 129 for transaction with financial institution 130, whether biometrics of the consumer match stored biometrics of consumer 129, whether the requested transaction and associated details (e.g., the identity of merchant 119, the location of merchant 119, the payment amount, the one or more items to be purchased (e.g., a list of SKUs), and/or other suitable factors) are consistent with spending patterns of consumer 129, whether consumer 129 has reported mobile device 120 lost or stolen, whether consumer 129 has reported that credit cards, debit cards, or other information about one or more of consumer accounts 131 have been lost or stolen, and/or other suitable factors.", "In various embodiments, financial institution 130 can adjust the level of authentication used to verify the identity of consumer 129 based on one or more of these factors, and/or based on the payment amount, the identity of merchant 119, the location of merchant 119, historical spending of consumer 129, and/or other relevant information.", "In some embodiments, if one or more of consumer accounts 131 chosen by consumer 129 for the transaction is short on funds or otherwise cannot be fully used, loan module 135 can communicate with loan module 126 to present other funding options to consumer 129, such as the option for a micro-loan to fund all or part of the transaction, as described above.", "In many embodiments, after receiving authorization from authorization module 133, financial institution 130 can initiate a payment to financial institution 150 to transfer funds from one or more of consumer accounts 131 to merchant account 151.In a number of embodiments, the payment can be effected by sending payment information regarding a payment to be made to merchant account 151 from one or more of consumer accounts 131.In a number of embodiments, the payment information transferred from financial institution 130 to financial institution 150 can effectuate an authenticated credit push, which can irrevocably satisfy payment to the merchant and/or ensure that the merchant has good funds when consumer 129 leaves the store of merchant 119.For example, the payment can be a settlement credit push of funds for the payment amount from one or more of consumer accounts 131 to merchant account 151, which can be settled immediately.", "In various embodiments, the payment information transferred from financial institution 130 to financial institution 150 can effectuate a push promise to pay, which can provide an irrevocable guarantee of payment from financial institution 130 to financial institution 150.In several embodiments, for example, the payment can be an ACH (Automated Clearing House) credit push, which can provide an irrevocable funding guarantee.", "In many embodiments, the payment and/or the guarantee of payment can be sent in real-time from financial institution 130 to financial institution 150, which can happen for each such transaction.", "In some embodiments, the settlement of the transaction can happen later, such as in a nightly batch fashion, and in some embodiments, can happen through a different network, such as an ACH network or a credit network.", "In other embodiments, the real-time payment and/or guarantee of payment can be processed through an ACH network or a credit network.", "In some embodiments, the consumer can provide instructions to financial institution 130 to label the transaction as a debit or a credit transaction in one or more of consumer accounts 131, and in some embodiments can provide such instructions with the request to pay, or before or after the request to pay.", "In some embodiments, a credit transaction can be treated as a micro-loan, as described above.", "In certain embodiments, a debit pull with guaranteed promise to pay can be used, such that financial institution 150 can receive a guaranteed promise to pay from financial institution 130 and pull the funds using a debit pull.", "In various embodiments, transaction system 140 can store information regarding each transaction in transaction database 142.In several embodiments, transaction system 140 can serve as a central auditor for transactions between the financial institutions (e.g., 130, 150) in data communication with transaction system 142.In some embodiments, transaction system 140 can receive some or all of the information from the merchant security transaction code.", "In various embodiments, one or more portions of the merchant security transaction code can be encrypted by security module 115.For example, the merchant security transaction code can include an encrypted portion that can be decrypted by security module 146 of transaction system 140, which can be used to ensure that the message has not been tampered.", "In other embodiments, the merchant security transaction code is not encrypted, but is digitally signed, as described above, and the digital signature can be verified, in some embodiments, by security module 146, which can advantageously ensure that the merchant identifier correctly identifies merchant 119, so that the funds are paid to merchant account 151 corresponding to merchant 119.In a number of embodiments, financial institution 150, upon receiving payment and/or guarantee of payment, can notify point-of-sale terminal 110 and/or merchant 119 in real-time that merchant 119 has satisfactorily received payment from consumer 129.For example, the notification can include various information, such as the transaction identifier, the amount received in payment (or guarantee), the merchant identifier, and/or other information.", "Receiving the notice of good funds can allow merchant 119 to proceed, such as, for example, to allow consumer to leave the store of merchant 119 with the items.", "In some embodiments, for example, point-of-sale terminal 110 can match the notification to the pending transaction in point-of-sale terminal 110 using the transaction identifier.", "In certain embodiments, merchant 119 can match the notification to the point-of-sale terminal using the merchant identifier.", "In some embodiments, consumer 129 can receive a notification on mobile device 120 that the transaction has cleared, such as shown in FIG.", "22 and described below.", "In several embodiments, system 100 can advantageously provide a number of technological improvements that can overcome technological problems in conventional systems.", "For example, in several embodiments, system 100 can beneficially allow consumer 129 to send payment directly and/or immediately to merchant 119 when consumer 129 is checking out at point-of-sale terminal 110.In many embodiments, the payment systems and methods provided by system 100 described herein can eliminate the acquirer model that is conventionally used in payment card transactions.", "In several embodiments, the payment systems and methods provided by system 100 described herein can advantageously streamline payments by eliminating the need for the financial institution (i.e., the acquirer) of merchant 119 to request payment from the financial institution (i.e., the issuer) of consumer 129.For example, in many embodiments, financial institution 150 does not need to request payment from financial institution 130.In many embodiments, the payment systems and methods provided by system 100 described herein can beneficially ensure merchants (e.g., merchant 119) are paid by consumers (e.g., consumer 129) while eliminating and/or reducing many of the transaction fees paid to various entities in the conventional model.", "In a number of embodiments, the payment systems and methods provided by system 100 described herein can advantageously eliminate the chargeback liability of merchants for fraudulent transactions.", "In the conventional acquirer-issuer model, the merchant (e.g., 119) is responsible for verifying the credit or debit card to ensure that the card is not being used fraudulently.", "In several embodiments, the payment systems and methods provided by system 100 described herein can beneficially place the liability on the financial institution (e.g., 130) of the consumer (e.g.", "129), which can be in a better position (e.g., with more and/or better information) than the merchant (e.g., 119) to determine if the request to pay is a legitimate, authentic transaction requested by the consumer (e.g., 129) and/or if the consumer's account is still open and in good status (or closed), has sufficient funds, etc.", "In various embodiments, the payment systems and methods provided by system 100 described herein can advantageously allow the financial institution (e.g., 130) of the consumer (e.g., 129) to choose how to authenticate the consumer (e.g., 129), and/or can beneficially allow the financial institution (e.g., 130) of the consumer (e.g., 129) to choose the level of authentication, which can be tailored for each consumer (e.g., 129) and/or for each transaction (e.g., the financial institution (e.g., 130) can decide, at least partially based on its risk determination, that a transaction with a higher payment amount warrants a higher level of authentication).", "In several embodiments, the liability for fraudulent use of one or more of the consumer accounts (e.g., 131) can be placed on the consumer (e.g., 129), and/or the consumer (e.g., 129) can choose the level of authentication used by the financial institution (e.g., 130) of the consumer (e.g., 129).", "In many embodiments, unauthorized access to one or more of consumer accounts 131 can beneficially be reduced and/or eliminated using the payment method provided by system 100 and described herein.", "In several embodiments, the payment systems and methods provided by system 100 described herein can beneficially provide the ability for financial institution 130 to communicate directly with consumer 129 at point-of-sale 110 when making a transaction.", "In many embodiments, the payment systems and methods provided by system 100 described herein can provide information to consumer 129, such as account balance, insufficient funds, lock/freeze on one or more of consumer accounts 131, etc., in real-time before consumer 129 requests payments, which can advantageously eliminate and/or reduce negative experiences of consumer 129, such as attempting to transact with insufficient funds or a freeze on one or more of consumer accounts 131.In a number of embodiments, the payment systems and methods provided by system 100 described herein can beneficially provide consumer 129 with the ability the ability to split the payment with one or more other accounts or a new loan, such as a micro-loan, which can allow consumer 129 to successfully make the payment and reduce negative experiences of consumer 129.In some embodiments, account information about one or more of consumer accounts 131 can beneficially be better protected from theft by the payment systems and methods provided by system 100 described herein, because, in a number of embodiments, the account information of one or more of consumer accounts 131 and/or personally identifiable information of consumer 129 can be undisclosed to third parties other than financial institution 130, which maintains consumer accounts 131.For example, in some embodiments, the account information of consumer accounts 131 and/or personally identifiable information of consumer 129 can be undisclosed to point-of-sale terminal 110, merchant 119, transaction system 140, and/or financial institution 150.In many embodiments, the account identifier (e.g., account number) of consumer accounts 131 is not sent across any networks, but resides solely in financial institution 130, which can beneficially prevent that information from being stolen.", "For example, the many recent large-scale data breaches of merchant systems that have exposed consumer account information and personally identifiable information of millions of consumers could have been mitigated by using the payment systems and methods provided by system 100 and described herein.", "In other embodiments, consumer 129 can choose to provide account information of one or more of consumer accounts 131 and/or personally identifiable information of consumer 129 to one or more third parties.", "For example, in some embodiments consumer 129 can set privacy instructions in mobile device 120 and/or with financial institution 130 regarding what information can be disclosed to third parties.", "For example, consumer 129 can elect to disclose certain information to merchant 119 in order to receive discounts, point, and/or other perks from merchant 119.For example, in some embodiments, financial institution 130 can send certain personally identifiable information of consumer 129 through transaction system 140 to financial institution 150 along with the payment information, and financial institution 150 can provide the information to merchant 119.In the same or other embodiments,

<EOH>The basis of the invention is a handheld medical device, (e.g., epidural needle, bone biopsy device, spinal needle, regional block needle, catheter introducer needle, etc.)", "having a penetrating member (e.g., an introducer needle, Tuohy needle, pencil point tipped needle, trocar needle (e.g., JAMSHIDI® biopsy needle), etc.", "), at a distal end, for use in procedures, (e.g., vascular entry and catheterization, single shot or continuous epidurals, spinal access, regional blocks, or bone biopsy, etc.", "), wherein the medical device comprises at least one driving actuator, (e.g., a piezoelectric, voice coil, solenoid, pneumatic, fluidic or any oscillatory or translational actuator etc.)", "attached to the penetrating member (e.g., at a proximal end of the penetrating member), and wherein the driving actuator translates the penetrating member, causing it to reciprocate at small displacements, thereby reducing the force required to penetrate through tissues.",

electrical, magnetic, pressure, capacitive, inductive, etc.", "means), to indicate successful penetration of various tissues, or of voids within the body such as the epidural space so that the clinician knows when to stop as well as to limit power to the driving mechanism.", "Actuator technologies that rely on conventional, single or stacked piezoelectric material assemblies for actuation are hindered by the maximum strain limit of the piezoelectric materials themselves.", "Because the maximum strain limit of conventional piezoelectric materials is about 0.1% for polycrystalline piezoelectric materials, such as lead zirconate titanate (PZT) polycrystalline (also referred to as ceramic) materials and 0.5% for single crystal piezoelectric materials, it would require a large stack of cells to approach useful displacement or actuation of, for example, a handheld medical device usable for processes penetrating through tissues.", "However, using a large stack of cells to actuate components of a handpiece would also require that the tool size be increased beyond usable biometric design for handheld instruments.", "Flextensional actuator assembly designs have been developed which provide amplification in piezoelectric material stack strain displacement.", "The flextensional designs comprise a piezoelectric material driving cell disposed within a frame, platen, endcaps or housing.", "The geometry of the frame, platten, endcaps or housing provides amplification of the axial or longitudinal motions of the driver cell to obtain a larger displacement of the flextensional assembly in a particular direction.", "Essentially, the flextensional actuator assembly more efficiently converts strain in one direction into movement (or force) in a second direction.", "Flextensional piezoelectric actuators may be considered mid-frequency actuators, e.g., 25-35 kHz.", "Flextensional actuators may take on several embodiments.", "For example, in one embodiment, flextensional actuators are of the Cymbal type, as described in U.S. Pat.", "No.", "5,729,077 (Newnham), which is hereby incorporated by reference.", "In another embodiment, flextensional

hereby incorporated by reference.", "In a preferred embodiment, the present invention comprises a handheld device including a body, a flextensional actuator disposed within said body and a penetrating or “sharps” member attached to one face of the flextensional actuator.", "In the broadest scope of the invention, the penetrating member may be hollow or solid.", "The actuator may have an internal bore running from a distal end to a proximal end or may have a side port located on the penetrating member attachment fitting.", "Therefore for single use penetrating members there is no need to sterilize the penetrating member after use.", "Where the penetrating member is hollow, it forms a hollow tubular structure having a sharpened distal end.", "The hollow central portion of the penetrating member is concentric to the internal bore of the actuator, together forming a continuous hollow cavity from a distal end of the actuator body to a proximal end of the penetrating member.", "For example, the flextensional actuator assembly may utilize flextensional Cymbal actuator technology or amplified piezoelectric actuator (APA) technology.", "The flextensional actuator assembly provides for improved amplification and improved performance, which are above that of a conventional handheld device.", "For example, the amplification may be improved by up to about 50-fold.", "Additionally, the flextensional actuator assembly enables handpiece configurations to have a more simplified design and a smaller format.", "One embodiment of the present invention is a resonance driven vascular entry needle to reduce insertion force of the penetrating member and to reduce rolling or collapsing of vasculature.", "An alternative embodiment of the present invention is a reduction of force epidural needle that provides the clinician a more controlled entry into the epidural space, minimizing the accidental puncturing of the dural sheath.", "In this embodiment, an actuator, for example, a Langevin actuator (more commonly referred to as a Langevin transducer), has a hollow penetrating member, for example a hollow needle, attached to a distal portion of the actuator.", "The Langevin actuator in this embodiment may be open at opposite ends.", "The openings include a hollow portion extending continuously from the distal end of the actuator to a proximal end of the actuator.", "The distal opening coincides with the hollow penetrating member.", "A plunger, having a handle, a shaft and a seal is also attached to the actuator at an opposite end of the

slidably disposed and, in response to a motion of the shaft in a distal direction, reduces the distal volume of the hollowed inner portion and increases the proximal volume.", "Conversely, in response to a motion of the shaft in a proximal direction, the seal also moves in a proximal direction, thereby reducing the proximal volume of the hollowed portion and increasing the distal volume.", "The motion of the plunger's shaft, and, effectively, the plunger's seal, is actuated by an external force acting on the plunger's handle.", "When electrically activated, the actuator transfers compression and expansion of the piezoelectric material portion to a hollow and penetrating tip of the hollow needle.", "Langevin actuators may be considered high :frequency actuators, e.g., >50 kHz.", "Another embodiment of the invention provides a bone marrow biopsy device having an outer casing, an actuator, for example, a Langevin actuator (e.g., see, for example, U.S. Pat.", "No.", "6,491,708 (Madan, et

end and an open proximal end with the cannula positioned at a distal portion of the actuator.", "In one aspect of the present embodiment, the invention further comprises a stylet having a penetrating distal tip attached to the handle at a portion opposite the distal tip, wherein the stylet is slidably disposed through a center cavity of the body and cannula.", "The actuator is formed with a distal opening formed at a distal end of the actuator, and a proximal opening formed at a proximal end of the actuator with a centralized hollow bore extending from the distal opening to the proximal opening, thereby defining a hollow channel.", "More precisely, the outer cannula is a hollow tube fixedly attached at the distal end of the actuator such that the open proximal end of the cannula coincides with the distal opening of the actuator distal end.", "The stylet is slidably and centrally disposed within the actuator from the proximal end through the hollow channel and through the distal end.", "The stylet is also of predetermined length such that it is slidably and centrally located through the outer cannula, with the distal tip of the stylet protruding past the open distal end of the cannula.", "The various actuators of the present invention must be connected electrically to an external electrical signal source.", "Upon excitation by the electrical signal, the actuators convert the signal into mechanical energy that results in vibratory motion of an end-effector, such as an attached needle or stylet.", "In the case of a Langevin actuator, the vibratory motion produced by the piezoelectric materials generates a standing wave through the whole assembly such as that in graph in FIG.", "17 .", "Because at a given frequency, a standing wave is comprised of locations of zero-displacement (node, or zero node) and maximum displacement (anti-node -not shown) in a continuous manner, the displacement that results at any point along the actuator depends on the location where the displacement is to be measured.", "Therefore, the horn is typically designed with such a length so as to provide the distal end of the horn at an anti-node when the device is operated.", "In this way, the distal end of the horn experiences a large vibratory displacement in a longitudinal direction with respect to the long axis of the actuator.", "Conversely, the zero node points are locations best suited for adding port openings or slots so as to make it possible to attach external devices to the actuator.", "As indicated by line ZN, the port opening SP coincides with the zero node location and the smaller displacement at zero node points are less abrasive to an attached device.", "Accordingly, an alternative embodiment, the actuator may be formed with a distal opening formed at the distal end of the actuator, a port opening on at least a portion of the actuator, and a hollow bore extending from the distal opening to and in communication with the port opening.", "Preferably, the port opening may be a side on a horn side of the actuator.", "More preferably, the port opening is generally located (preferably centered) at a zero node location of the actuator, and most preferably centered at a zero node location on a horn side of the actuator.", "Additionally, a means for providing feedback, for example any of those conventional feedback devices disclosed above used for indication of successful body location such as the epidural space penetration is in communication with the present embodiment by attachment at the port opening location, or preferably at the side port.", "Alternatively, any means capable of delivering fluid, such as a catheter tube or conventional syringe can be attached at the port opening location, or preferably at the side port.", "The present invention relates generally to oscillatory or translational actuated handheld device for penetration through various tissues within a body for the delivery or removal of bodily fluids, tissues, nutrients, medicines, therapies, placement or removal of catheters, etc.", "For example for piezoelectric devices, the present invention is a handpiece including a body, at least one piezoelectric element disposed within the body, and a sharps member for tissue penetration, such as a syringe, epidural needle or biopsy needle located at a distal portion of the handheld device, having a feedback means capable of indicating successful penetration of the body space, such as epidural space by providing visual, audible or tactile indications using any well-known detection mechanisms such as but not limited to electrical, magnetic, pressure, capacitive, inductive, etc.", "means.", "Additionally, with the use of proper circuitry the handheld medical device comprising an actuator is provided with a means for shutting off external power to the driving actuator (e.g., one or more of piezoelectric elements, voice coil, solenoid, other oscillatory or

may be implemented as part of the aforementioned means for providing visual, audible or tactile indications or may be a separate means altogether.", "Preferably the means for shutting off external power to the driving actuator upon penetration of a particular tissue or internal portion of for example, the epidural space, may be accomplished by incorporating proper circuit configurations to aforementioned electrical means to trigger a switching means in order to cut off power to the driving actuator.", "Such a means is described in U.S. Pat.", "No.", "5,575,789 (Bell et al.)", "whose entire disclosure is incorporated by reference herein.", "By providing such electrical cut-off means, upon successfully penetrating the epidural space for example, a clinician receives one or more of a visual, audible, and tactile indications as well as a loss of power to the device as a secondary indication that a particular internal portion of a body has been penetrated.", "Furthermore, with a loss of power to the device by cutting off electrical power to the driving actuator, the force or forward momentum necessary for further penetration of tissue will cease and in turn, will decrease the potential for unwanted body area puncture such as accidental dural puncture.", "Additionally the invention with specific control electronics will provide reduction of force as the penetrating member is retracted from the body.", "In one embodiment, the penetrating or sharp tubular member is a part of a vascular entry needle.", "In another embodiment, the penetrating sharp tubular member is a

needles.", "The invention is applicable to the delivery and removal of blood, tissues, medicine, bone marrow, nutrients or other materials within the body.", "DESCRIPTION OF RELATED ART Epidural anesthesia is a form of regional anesthesia involving injection of drugs directly into the epidural space.", "To begin the procedure, a needle is inserted from the outer layer of skin, through several layers of tissue and finally placed within the epidural space, through which a catheter is optionally passed.", "Local anesthetics are injected into the epidural space causing temporary loss of sensation and pain by blocking the transmission of pain signals through nerves in or near the spinal cord.", "The procedure can be unpleasant to the patient because of the high force levels required for the relatively dull epidural needle to penetrate the supraspinous ligament, interspinous ligament and ligamentum flavum.", "One complication is that a clinician will accidently overshoot and puncture the dura because of this high force of penetration and an almost-instantaneous change in resistance upon passing the needle into the epidural space (i.e., high forward momentum followed by instantaneous minimization of force).", "Upon puncturing the dura, the cerebrospinal fluid can leak into the epidural space causing the patient to experience severe post dural puncture headache, lasting from days to possibly years.", "Significant leakage can cause enough intracranial hypotension as to tear veins, cause subdural hematoma, and traction injuries to the cranial nerves resulting in tinnitus, hearing loss, dizziness, facial droop, or double vision.", "A bone marrow biopsy is used for diagnosing tumors and a variety of bone diseases.", "The most commonly used site for the bone biopsy is the anterior iliac crest.", "A major disadvantage is the force required to penetrate the bone tissue, and the twisting motion often used to force the needle inward, which results in patient discomfort as well as possible healing complications from damaged tissues.", "The penetration force can also be tiring for clinicians and lead to multiple sampling attempts.", "Complications are rare but can include bleeding, pain, and infection.", "Pain is minimized with proper local anesthesia, though the patient still experiences a pressure sensation during insertion and retraction during some procedures.", "Another problem is crushing the sample or being unable to retrieve part of all of it, limiting the ability to diagnose.", "As shown in FIG.", "1, a biopsy tool PA1 typically comprises a handle (not shown) and hollow cannula 1 with cannula distal end 1′ surrounding a stylet 2 attached to the handle.", "To penetrate through cortical bone, a clinician pushes the cannula and stylet through the bone to the marrow.", "The distal tip 3 of the inner stylet or trocar is sharpened and has an angled chisel-like face 4 which reduces the surface area to reduce the exertion force.", "Currently, to minimize the possibility of a dura puncture, the epidural catheter insertion process is typically performed very slowly and with a 16-18 gauge, specially designed, relatively dull needle PA2, such as the one shown in FIG.", "2 called a Tuohy needle 5.An epidural needle, such as the Tuohy needle 5 or Hustead needle, has a directional curved tip 6, which decreases the “sharpness” at the needle and, therefore, makes accidental dura puncture more difficult.", "The curved tip also facilitates directing an indwelling catheter into the epidural space and a tip opening 7 facilitates catheter or fluid introduction or removal.", "Unfortunately, this dull curved-tip design actually increases the force a clinician must use and makes it more difficult for a clinician to stop the forward momentum upon penetration of the dural space.", "Additionally, the Tuohy design increases the likelihood that a clinician relies on tactile feedback during penetration.", "In other words, during the insertion procedure a clinician will rely on feeling a “popping” sensation—indicative of passing the needle past the ligamentum flavum—to locate the tip of the needle within the epidural space and quickly stop the forward momentum being applied.", "Still, because penetration into other tissues, such as muscle, calcified ligament, or regular ligament may produce a similar popping, a clinician may not fully perceive the correct location of the needle tip where the tip of the needle is occluded until passing through these tissues.", "Several alternate technologies have been developed that attempt to minimize the dura puncture risk, while also giving the clinician indication of successful epidural placement.", "For example, the detection method and apparatus disclosed in U.S. Patent Application Publication No.", "2007/0142766 (Sundar, et al.", "), the contents of which are incorporated by reference, relies on a spring-loaded plunger pushing a fluid into the epidural space upon successful entry.", "Accordingly, the clinician is given a visual indicator (i.e., the movement of the plunger as the fluid experiences a loss of resistance at the needle opening), and would cease applying forward force.", "Similarly, U.S. Pat.", "No.", "5,681,283 (Brownfield) also relies on a visual indicator to communicate successful entry of a needle into a cavity to the clinician.", "Unfortunately, while a visual indicator is a positive advancement, the actual cause of the accidental dural wall puncture-that is, the high force applied by the clinician against the needle to pass through the various tissue layers and then stop-is not taught or suggested.", "Therefore, there exists a need for a tool that reduces the puncture force of a needle, such as a Tuohy needle, and enables a clinician to perform a more controlled entry into the epidural space, thereby reducing the possibility of an accidental dura puncture.", "While accidental dura puncture is a concern, simply locating the epidural space may pose a challenge even to the most skilled physicians.", "Therefore, when a needle such as a Tuohy needle is passed through the ligamentum flavum and into the epidural space, it is helpful for a clinician to receive immediate feedback indicating successful penetration and the location of the tip of the needle.", "A basic conventional feedback device such as the one in FIG.", "2a comprises a needle (not shown) attached to a syringe PA3 at a front portion 9, and wherein the syringe PA3 is formed of a tubular body 10 and houses a biasing element 11 comprising a stem acting as a biasing element.", "To provide feedback indicating successful epidural penetration the device relies on a biasing force acting against the biasing element 11 which then acts upon a fluid, such as saline, or air within the syringe.", "Essentially, in this hydraulic feedback method, as the biasing force acts upon the fluid, the fluid translates this pressure to an opening of the needle tip.", "An opposing force, acting on the needle tip as it is held against a tissue such as the ligamentum flavum, acts to prevent the fluid from being released from the syringe.", "Typically, a clinician's thumbs act as the biasing force source which in turn acts upon the plunger stem.", "The clinician's thumbs serve to “feel” the hydraulic resistance exerted on the fluid by the opposing tissue force.", "Upon entering the epidural space, however, the opposing pressure of tissue acting against the tip is removed, and a pressure drop allows the biasing force to move solution out of the syringe through the needle tip.", "The clinician becomes aware of successful penetration of the epidural space due to his/her thumbs “feeling” the sudden pressure drop or loss of resistance at the plunger stem.", "Also, the clinician may receive visual indication of successful penetration by witnessing the plunger advancing through the syringe externally as the fluid is released into the epidural space in the patient.", "One problem with this conventional device and method is that it is difficult for a clinician to both apply a biasing force on the plunger while also applying an advancing force against the syringe body in order to advance the needle through the ligamentum flavum.", "Moreover, to prevent accidental dura puncture, clinicians tend to hold the conventional syringe in such a way as to hold the patient steady, while applying a forward momentum against the syringe, and while applying a biasing force against the plunger stem.", "This is both awkward and uncomfortable to the clinician and patient.", "Some advancements have also attempted to provide an automatic biasing element to act against the plunger of an epidural syringe while also

"2007/0142766 (Sundar et al.", "), a spring is utilized to act with a biasing force against the syringe plunger.", "When the epidural needle attached to the syringe passes through into the dural space, the pressure drop allows the spring to bias the plunger.", "As the plunger moves, the stem provides at least some visual indication as it moves with the plunger.", "Similarly, U.S. Pat.",

addition, U.S. Pat.", "No.", "7,297,131 (Call) which is hereby incorporated by reference, uses a pressure transducer to translate a pressure change into an electronic signal.", "The electronic signal

THE INVENTION The basis of the invention is a handheld medical device, (e.g., epidural needle, bone biopsy device, spinal needle, regional block needle, catheter introducer needle, etc.)", "having a penetrating member (e.g., an introducer needle, Tuohy needle, pencil point tipped needle, trocar needle (e.g., JAMSHIDI® biopsy needle), etc.", "), at a distal end, for use in procedures, (e.g., vascular entry and catheterization, single shot or continuous epidurals, spinal access, regional blocks, or bone biopsy, etc.", "), wherein the medical device comprises at least one driving actuator, (e.g., a piezoelectric, voice coil, solenoid, pneumatic, fluidic or any oscillatory or translational actuator etc.)", "attached to the penetrating member (e.g., at a proximal end of the penetrating member), and wherein the driving actuator translates the penetrating member, causing it to reciprocate at small displacements, thereby reducing the force required to penetrate through tissues.", "Additionally, the invention comprises a means for providing feedback, either visually, audibly, or by tactile response, using a variety of detection mechanisms (such as, but not limited to, electrical, magnetic, pressure, capacitive, inductive, etc.", "means), to indicate successful penetration of various tissues, or of voids within the body such as the epidural space so that the clinician knows when to stop as well as to limit power to the driving mechanism.", "Actuator technologies that rely on conventional, single or stacked piezoelectric material assemblies for actuation are hindered by the maximum strain limit of the piezoelectric materials themselves.", "Because the maximum strain limit of conventional piezoelectric materials is about 0.1% for polycrystalline piezoelectric materials, such as lead zirconate titanate (PZT) polycrystalline (also referred to as ceramic) materials and 0.5% for single crystal piezoelectric materials, it would require a large stack of cells to approach useful displacement or actuation of, for example, a handheld medical device usable for processes penetrating through tissues.", "However, using a large stack of cells to actuate components of a handpiece would also require that the tool size be increased beyond usable biometric design for handheld instruments.", "Flextensional actuator assembly designs have been developed which provide amplification in piezoelectric material stack strain displacement.", "The flextensional designs comprise a piezoelectric material driving cell disposed within a frame, platen, endcaps or housing.", "The geometry of the frame, platten, endcaps or housing provides amplification of the axial or longitudinal motions of the driver cell to obtain a larger displacement of the flextensional assembly in a particular direction.", "Essentially, the flextensional actuator assembly more efficiently converts strain in one direction into movement (or force) in a second direction.", "Flextensional piezoelectric actuators may be considered mid-frequency actuators, e.g., 25-35 kHz.", "Flextensional actuators may take on several embodiments.", "For example, in one embodiment, flextensional actuators are of the Cymbal type, as described in U.S. Pat.", "No.", "5,729,077 (Newnham), which is hereby incorporated by reference.", "In another embodiment, flextensional actuators are of the amplified piezoelectric actuator (“APA”) type as described in U.S. Pat.", "No.", "6,465,936 (Knowles), which is hereby incorporated by reference.", "In yet another embodiment, the actuator is a Langevin or bolted dumbbell-type actuator, similar to, but not limited to that which is disclosed in U.S. Patent Application Publication No.", "2007/0063618 A1 (Bromfield), which is hereby incorporated by reference.", "In a preferred embodiment, the present invention comprises a handheld device including a body, a flextensional actuator disposed within said body and a penetrating or “sharps” member attached to one face of the flextensional actuator.", "In the broadest scope of the invention, the penetrating member may be hollow or solid.", "The actuator may have an internal bore running from a distal end to a proximal end or may have a side port located on the penetrating member attachment fitting.", "Therefore for single use penetrating members there is no need to sterilize the penetrating member after use.", "Where the penetrating member is hollow, it forms a hollow tubular structure having a sharpened distal end.", "The hollow central portion of the penetrating member is concentric to the internal bore of the actuator, together forming a continuous hollow cavity from a distal end of the actuator body to a proximal end of the penetrating member.", "For example, the flextensional actuator assembly may utilize flextensional Cymbal actuator technology or amplified piezoelectric actuator (APA) technology.", "The flextensional actuator assembly provides for improved amplification and improved performance, which are above that of a conventional handheld device.", "For example, the amplification may be improved by up to about 50-fold.", "Additionally, the flextensional actuator assembly enables handpiece configurations to have a more simplified design and a smaller format.", "One embodiment of the present invention is a resonance driven vascular entry needle to reduce insertion force of the penetrating member and to reduce rolling or collapsing of vasculature.", "An alternative embodiment of the present invention is a reduction of force epidural needle that provides the clinician a more controlled entry into the epidural space, minimizing the accidental puncturing of the dural sheath.", "In this embodiment, an actuator, for example, a Langevin actuator (more commonly referred to as a Langevin transducer), has a hollow penetrating member, for example a hollow needle, attached to a distal portion of the actuator.", "The Langevin actuator in this embodiment may be open at opposite ends.", "The openings include a hollow portion extending continuously from the distal end of the actuator to a proximal end of the actuator.", "The distal opening coincides with the hollow penetrating member.", "A plunger, having a handle, a shaft and a seal is also attached to the actuator at an opposite end of the sharps member.", "The plunger's shaft is slidably disposed within the continuous, hollowed inner portion of the actuator.", "The seal is attached to a distal portion of the plunger's shaft and separates a distal volume of the hollowed inner portion of the actuator from a proximal volume of the hollowed inner portion.", "Because the plunger's shaft is slidably disposed, the plunger is also slidably disposed and, in response to a motion of the shaft in a distal direction, reduces the distal volume of the hollowed inner portion and increases the proximal volume.", "Conversely, in response to a motion of the shaft in a proximal direction, the seal also moves in a proximal direction, thereby reducing the proximal volume of the hollowed portion and increasing the distal volume.", "The motion of the plunger's shaft, and, effectively, the plunger's seal, is actuated by an external force acting on the plunger's handle.", "When electrically activated, the actuator transfers compression and expansion of the piezoelectric material portion to a hollow and penetrating tip of the hollow needle.", "Langevin actuators may be considered high :frequency actuators, e.g., >50 kHz.", "Another embodiment of the invention provides a bone marrow biopsy device having an outer casing, an actuator, for example, a Langevin actuator (e.g., see, for example, U.S. Pat.", "No.", "6,491,708 (Madan, et al.", "), whose entire disclosure is incorporated by reference herein), including a first body portion and a second body portion of the actuator, with piezoelectric material formed between the first and second body portions, wherein the actuator is disposed at least partially within the casing.", "The invention further includes a handle, an outer cannula, such as a needle, having an open distal end and an open proximal end with the cannula positioned at a distal portion of the actuator.", "In one aspect of the present embodiment, the invention further comprises a stylet having a penetrating distal tip attached to the handle at a portion opposite the distal tip, wherein the stylet is slidably disposed through a center cavity of the body and cannula.", "The actuator is formed with a distal opening formed at a distal end of the actuator, and a proximal opening formed at a proximal end of the actuator with a centralized hollow bore extending from the distal opening to the proximal opening, thereby defining a hollow channel.", "More precisely, the outer cannula is a hollow tube fixedly attached at the distal end of the actuator such that the open proximal end of the cannula coincides with the distal opening of the actuator distal end.", "The stylet is slidably and centrally disposed within the actuator from the proximal end through the hollow channel and through the distal end.", "The stylet is also of predetermined length such that it is slidably and centrally located through the outer cannula, with the distal tip of the stylet protruding past the open distal end of the cannula.", "The various actuators of the present invention must be connected electrically to an external electrical signal source.", "Upon excitation by the electrical signal, the actuators convert the signal into mechanical energy that results in vibratory motion of an end-effector, such as an attached needle or stylet.", "In the case of a Langevin actuator, the vibratory motion produced by the piezoelectric materials generates a standing wave through the whole assembly such as that in graph in FIG.", "17.Because at a given frequency, a standing wave is comprised of locations of zero-displacement (node, or zero node) and maximum displacement (anti-node -not shown) in a continuous manner, the displacement that results at any point along the actuator depends on the location where the displacement is to be measured.", "Therefore, the horn is typically designed with such a length so as to provide the distal end of the horn at an anti-node when the device is operated.", "In this way, the distal end of the horn experiences a large vibratory displacement in a longitudinal direction with respect to the long axis of the actuator.", "Conversely, the zero node points are locations best suited for adding port openings or slots so as to make it possible to attach external devices to the actuator.", "As indicated by line ZN, the port opening SP coincides with the zero node location and the smaller displacement at zero node points are less abrasive to an attached device.", "Accordingly, an alternative embodiment, the actuator may be formed with a distal opening formed at the distal end of the actuator, a port opening on at least a portion of the actuator, and a hollow bore extending from the distal opening to and in communication with the port opening.", "Preferably, the port opening may be a side on a horn side of the actuator.", "More preferably, the port opening is generally located (preferably centered) at a zero node location of the actuator, and most preferably centered at a zero node location on a horn side of the actuator.", "Additionally, a means for providing feedback, for example any of those conventional feedback devices disclosed above used for indication of successful body location such as the epidural space penetration is in communication with the present embodiment by attachment at the port opening location, or preferably at the side port.", "Alternatively, any means capable of delivering fluid, such as a catheter tube or conventional syringe can be attached at the port opening location, or preferably at the side port.", "The present invention relates generally to oscillatory or translational actuated handheld device for penetration through various tissues within a body for the delivery or removal of bodily fluids, tissues, nutrients, medicines, therapies, placement or removal of catheters, etc.", "For example for piezoelectric devices, the present invention is a handpiece including a body, at least one piezoelectric element disposed within the body, and a sharps member for tissue penetration, such as a syringe, epidural needle or biopsy needle located at a distal portion of the handheld device, having a feedback means capable of indicating successful penetration of the body space, such as epidural space by providing visual, audible or tactile indications using any well-known detection mechanisms such as but not limited to electrical, magnetic, pressure, capacitive, inductive, etc.", "means.", "Additionally, with the use of proper circuitry the handheld medical device comprising an actuator is provided with a means for shutting off external power to the driving actuator (e.g., one or more of piezoelectric elements, voice coil, solenoid, other oscillatory or translational actuator, etc.)", "upon penetration of a particular tissue or internal portion of a body such as the epidural space.", "The means for shutting off external power to the driving actuator may be implemented as part of the aforementioned means for providing visual, audible or tactile indications or may be a separate means altogether.", "Preferably the means for shutting off external power to the driving actuator upon penetration of a particular tissue or internal portion of for example, the epidural space, may be accomplished by incorporating proper circuit configurations to aforementioned electrical means to trigger a switching means in order to cut off power to the driving actuator.", "Such a means is described in U.S. Pat.", "No.", "5,575,789 (Bell et al.)", "whose entire disclosure is incorporated by reference herein.", "By providing such electrical cut-off means, upon successfully penetrating the epidural space for example, a clinician receives one or more of a visual, audible, and tactile indications as well as a loss of power to the device as a secondary indication that a particular internal portion of a body has been penetrated.", "Furthermore, with a loss of power to the device by cutting off electrical power to the driving actuator, the force or forward momentum necessary for further penetration of tissue will cease and in turn, will decrease the potential for unwanted body area puncture such as accidental dural puncture.", "Additionally the invention with specific control electronics will provide reduction of force as the penetrating member is retracted from the body.", "In one embodiment, the penetrating or sharp tubular member is a part of a vascular entry needle.", "In another embodiment, the penetrating sharp tubular member is a Tuohy needle.", "In yet another embodiment, the penetrating or sharp tubular member is a trocar and stylet assembly, such as a JAMSHIDI® biopsy needle.", "In yet another embodiment, the penetrating or

the aforementioned preferred embodiments, utilizes reduction of force to optimize penetrating through tissue or materials found within the body.", "Essentially, when tissue is penetrated by the high speed operation of a penetrating member portion of the device, such as a needle, the force required for entry is reduced.", "In other words, a reduction of force effect is observed when a penetrating member (also referred to as a “tubular member”), for example a needle, is vibrated axially (e.g., reciprocated) during the insertion process and enough mechanical energy is present to break adhesive bonds between tissue and the penetrating member.", "The threshold limits of energy can be reached in the sonic to ultrasonic frequency ranges if the necessary amount of needle displacement is present.", "To exploit the reduction of force effect, the medical device of the present invention is designed such that the penetrating distal tip portion attains a short travel distance or displacement, and vibrates sinusoidally with a high penetrating frequency.", "Utilizing the various device configurations as described in the aforementioned embodiments, it has been determined that the sinusoidal motion of the sharp distal tip must include a displacement for piezoelectric tools of between 35-100 μm, more preferably between 50-100 μm, at a frequency of between 20-50 kHz, but most preferably at 20-25 kHz.", "This motion is caused by the penetrating member 20 being attached to an actuating piezoelectric actuator operated at 50-150 Vpp/mm, but most preferably at 90 Vpp/mm where Vpp is known as the peak-to-peak voltage.", "For example, FIG.", "3 shows a graphical representation of the resisting force versus depth of a bone biopsy needle penetrating into hard tissue.", "In FIG.", "3, the curve labeled A represents data for a needle in an “off' or non-vibrating condition and the curve labeled B represents data for a medical device having a needle that is vibrated by a piezoelectric actuator at 38 kHz and a displacement of 100 μm.", "As apparent from FIG.", "3, curve A shows that without being vibrated, the force necessary to penetrate into a material is much higher

the MFD 1 includes a main chassis 2 and a reader unit 10.The MFD 1 further includes an image forming unit 4 to form an image on a sheet P being fed and a feeder unit 3 to feed the sheet P to the image forming unit 4, which are contained in the main chassis 2.The main chassis 3 includes paths, such as a conveyer path 130, a first discharge path 81, a second discharge path 91, and a duplex conveyer path 121, in which the sheet P may be conveyed.", "These paths may include members and/or parts that form the paths.", "The main chassis 2 includes a front wall 2F, a rear wall 2R, an upper wall 2U, and a pair of lateral frames 2S that are disposed on a leftward side and a rightward side of the upper wall 2U.", "The upper wall 2U includes a front part and a rear part.", "The front part of the upper wall 2U includes a discharge tray 21, which includes a placement surface 21F to support the sheet P from below.", "The rear part of the upper wall 2U includes a switchback tray 22, which includes a placement surface 22F to support the sheet P from below.", "The discharge tray 21 and the switchback tray 22 are arranged in different vertical levels, and the switchback tray 22 is disposed in an upper position with respect to the discharge tray 21.An upper part of the rear wall 2R includes an upper discharge tray 23, which supports the sheet P from behind.", "Detailed configuration of the main chassis 2 will be described later.", "The reader unit 10 may be a flatbed scanner having a known configuration.", "The reader unit 10 may cast light onto an original sheet (not shown) and read an image of the original sheet to generate image data, which may be used to make a duplicate of the read image.", "The reader unit 10 may be disposed in an upper position with respect to the switchback tray 22 so that space may be formed between the switchback tray 22 and the reader unit 10, and widthwise ends of the reader unit 10 may be supported sideward by the lateral frames 2S (see FIG.", "6).", "For example, the reader unit 10 may be supported pivotably by the lateral frames 2S at a rear end thereof through a pivot shaft 11 so that a front part of the reader unit 10 may pivot about the pivot shaft 11 vertically (see FIG.", "2).", "Meanwhile, the lateral frames 2S may have a stopper ST, which is resilient and engageable with the discharge tray 21 when the reader unit 10 pivots upward, to hold the discharge tray 21, so that the reader unit 10 pivoted upward may be supported by the stopper ST through the discharge tray 21 and held steadily at the upper position.", "The feeder unit 3 is disposed in a lower position in the main chassis 2 and includes a feeder tray 31, in which the sheets P to be fed are placed, and a feeding system 32 to feed the sheets P in the feeder tray 31 are fed to the image forming unit 4 one by one.", "The feeder tray 31 is detachably attached to the main chassis 2 and includes a feeder tray 31A (see FIG.", "1), in which sheets P having a length smaller than or equal to a predetermined length, such as A4-sized sheets or letter-sized sheets, may be stored, and a larger feeder tray 31B (see FIG.", "4), in which sheets P having a length greater than the predetermined length, such as A3-sized sheets or tabloid-sized sheets, may be stored.", "In other words, the feeder trays 31A, 31B for different-sized sheets P may be attached to the main chassis 2.The image forming unit 4 includes a scanner unit 5, a processing cartridge 6, and a fixing unit 7.The scanner unit 5 is disposed in a frontward position in the main chassis 2 and includes a laser emitter, polygon mirrors, lenses, and reflection mirrors, which are not shown.", "In the scanner unit 5, a laser beam may be emitted at a surface of a photosensitive drum 61 in the processing cartridge 6 to scan the surface of the photosensitive drum 61.The processing cartridge 6 is disposed in a rearward position with respect to the scanner unit 5 and includes the photosensitive drum 61, a transfer roller 62, a charger 63, a developer roller 64, a supplier roller 65, and a toner container 66.In the processing cartridge 6, while the photosensitive drum 61 rotates, the surface of the photosensitive drum 61 is electrically charged by the charger 63 evenly and exposed partly to the laser beam emitted from the scanner unit 5 so that electrical charges of the exposed areas are lowered and a latent image according to image data is formed to be carried on the surface of the photosensitive drum 51.Meanwhile, the toner in toner container 66 is supplied to the latent image on the photosensitive drum 61 through the developer roller 64 while the developer roller 64 rotates so that the latent image on the photosensitive drum 61 is developed to be a toner image.", "In the meantime, as the sheet P is conveyed by the feeding system 32 and by a plurality of conveyer roller pairs 131 in the conveyer path 130, from a lower position with respect to the scanner unit 5, through a lowest position 130A, which is in a lower position with respect to the toner container 66, and through a registration roller pair 132, to a position between the photosensitive drum 61 and the transfer roller 62.As the sheet P is conveyed through the position between the photosensitive drum 61 and the transfer roller 62, the toner image carried on the surface of the photosensitive drum 61 is transferred onto the sheet P. The fixing unit 7 is disposed in an upper-rearward position with respect to the processing cartridge 6 and includes a heat roller 71, a pressure roller 72, and a conveyer roller 73.In the fixing unit 7, the toner image transferred to the sheet S is thermally fixed thereon as the sheet S is conveyed through a position between the heat roller 71 and the pressure roller 72.The sheet P with the thermally-fixed image is discharged by the conveyer roller 73 out of the fixing unit 7.In positions on a downstream side of the fixing unit 7 with regard to a conveying direction to convey the sheet P, disposed are a first discharge unit 8, which may discharge the sheet P conveyed through the image forming unit 4, more specifically the fixing unit 7, to the discharge tray 21, and a second discharge unit 9, which may convey the sheet P conveyed through the image forming unit 4, more specifically the fixing unit 7, to either the switchback tray 22 or the upper discharge tray 23.The first discharge unit 8 includes the first discharge path 81, a discharge roller 82, a first outlet 24A, and the discharge tray 21.The first discharge path 81 is formed to extend upward from the conveyer roller 73 and to curve frontward.", "The discharge roller 82 conveys the sheet P in the first discharge path 81 to discharge through the first outlet 24A onto the discharge tray 21.The discharge roller 82 is controlled by a controller 100 to rotate in a normal direction, which is a direction to convey and discharge the sheet P outward through the first outlet 24A.", "The second discharge unit 9 includes the second discharge path 91, a switchback roller 92, an L-shaped guide 93, the switchback tray 22, and the upper discharge tray 23.The second discharge path 91 is formed to extend substantially linearly upper-rearward from the conveyer roller 73.Therefore, a minimum radius of curvature in the second discharge path 91 is greater than a minimum radius of curvature in the first discharge path 81.The switchback roller 92 includes paired rollers which are arranged to face with each other along the front-rear direction.", "The switchback roller 92 is rotatable in a normal direction, which is a direction to convey the sheet P outward to the switchback tray 22 or the upper discharge tray 23, and in a reverse direction, which is an opposite direction from the normal direction.", "In other words, the switchback roller 92 is rotatable to convey the sheet P in the second discharge path 91 upward and downward.", "The switchback roller 92 is disposed in a rearward and spaced-apart position from the discharge roller 82.In other words, the discharge roller 82 is in a frontward position with respect to the switchback roller 92.Thus, the discharge roller 82 is disposed on a frontward side of the switchback tray 22, and the switchback roller 92 is disposed on another side, on a rearward side, of the switchback tray 22 opposite from the discharge roller 82.The L-shaped guide 93 is a guide member including a guiding parts 93, a part of which may be placed between the switchback roller 92 and the switchback tray 22, to guide the sheet P conveyed upward by the switchback roller 92 toward the switchback tray 22.The L-shaped guide 93 is supported pivotably by the main chassis 2, or more specifically, by the lateral frames 2S.", "The L-shaped guide 93 is pivotable between a guiding position (see FIG.", "1), in which the L-shaped guide 93 may guide the sheet P toward the switchback tray 22, and a non-guiding position (indicated by solid lines in FIG.", "5A), in which the sheet P may be conveyed to the upper discharge tray 23.More specifically, when the L-shaped guide 93 is in the guiding position, the L-shaped guide 93 may contact the sheet P being conveyed upward by the switchback roller 92 and guide the sheet P to be conveyed toward the switchback tray 22.When the L-shaped guide 93 is in the non-guiding position, the L-shaped guide 93 does not interfere with the sheet P being conveyed upward by the switchback roller 92 so that the sheet P is allowed to be conveyed toward the upper discharge tray 23.Thus, by switching the positions of the L-shaped guide 93 between the guiding position and the non-guiding position, courses of the sheet P may be switched between a course to the switchback tray 22 and a course to the upper discharge tray 23.The L-shaped guide 93 will be described later in detail.", "A switch member 110 to switch the courses for the sheet P is disposed in a position between the first discharge path 81 and the second discharge path 91.The switch member 110 is swingably supported by the main chassis 2, or more specifically, the lateral frames 2S.", "The switch member 110 may swing between a first guiding position, which is indicated by solid lines in FIG.", "1, and a second guiding position, which is indicated by broken lines in FIG.", "1.In the first guiding position, the switch member 110 may guide the sheet P to the first discharge path 81.In the second guiding position, the switch may guide the sheet P to the second discharge path 91.On a rear side of the main chassis 2, disposed is a duplex conveyer 120, which may invert the sheet P conveyed through the image forming unit 4 and convey the inverted sheet P once again to the image forming unit 4.The duplex conveyer 120 includes the switchback roller 92, the L-shaped guide 93, the switchback tray 22, the upper discharge tray 23, and the duplex conveyer path 121, which are mentioned earlier.", "The duplex conveyer path 121 is formed to extend from the second discharge path 91 to one of the registration roller pairs 130, which is at a frontward position with respect to a nipping position between the photosensitive drum 61 and the transfer roller 62.The duplex conveyer path 121 extends from the second discharge path 91 downward along a rear side of the fixing unit 7, curves frontward along a lower side of the fixing unit 7 and the photosensitive drum 61, and curves upper-rearward toward the nipping position between the photosensitive drum 61 and the transfer roller 62.The controller 100 includes a central processing unit (CPU), a random-access memory (RAM), a read-only memory (ROM), and input/output (I/O) circuits, which are not shown, and controls behaviors of each part and component in the MFD 1, including the first discharge unit 8, the second discharge unit 9, and the duplex conveyer 120.For example, the controller 100 may control the switch member 110 and the L-shaped guide 93 to switch positions thereof and may control rotations of the rollers including the discharge roller 82 and the switchback roller 92.The controller 100 may perform a switchback control, in which the rotating directions of the switchback roller 92 may be switched while the switchback roller 92 conveys the sheet P upward so that the sheet P may be switched back downward, and an output control, in which the switchback roller 92 may be maintained to rotate in the normal direction to convey the sheet P to either the switchback tray 22 or to the upper discharge tray 23.For example, when the sheet P1 is to be discharged to the discharge tray 21, as shown in FIG.", "4, the controller 100 may place the switch member 110 in the first guiding position, as indicated by the solid lines, and drive the discharge roller 82 to rotate in the normal direction, which is the direction to discharge the sheet P outward.", "For another example, when the sheet P is to be conveyed to the switchback tray 22, the controller 100 may place the switch member 110 in the second guiding position, as indicated by the broken lines; place the L-shaped guide 93 in the guiding position, as indicated by the solid lines; and drive the switchback roller 92 to rotate in the normal direction, which is the direction to discharge the sheet P outward.", "In the MFD 1 according to the present embodiment, a sheet P2 having a greater length, such as an A3-sized sheet and a tabloid-sized sheet, may be preferably conveyed or discharged to the switchback tray 22, as shown in FIG.", "4.The sheet P2 having the greater length may be preferably supported by the switchback tray 22 and the discharge tray 21.Meanwhile, the controller 100 may place the switch member 110 in the second guiding position, as indicated by the broken lines in FIG.", "4, and drive the switchback roller 92 to rotate in the normal direction, which is the direction to discharge the sheet P outward, when the sheet P3 is to be discharged to the upper discharge tray 23.Further, when the sheet P having an image printed on one side thereof is conveyed to return to the image forming unit 4, the controller 100 may place the switch member 110 in the second guiding position and the L-shaped guide 93 in either the guiding position or the non-guiding position, and drive the switchback roller 92 to rotate in the normal direction so that the sheet P may be conveyed once in the normal direction toward to the switchback tray 22 or the upper discharge tray 23, and thereafter, before the sheet P exits the switchback roller 92, the controller 100 may switch the rotating directions of the switchback roller 92 conveyed to drive the switchback roller 92 to rotate in the reverse direction.", "[Configurations of the Main Chassis and the L-Shaped Guide] Configurations of the main chassis 2 and the L-shaped guide 93 in the MFD 1 will be described below in detail.", "As shown in FIG.", "1, the upper wall 2U of the main chassis 2 includes the discharge tray 21, the switchback tray 22, and a vertical wall 24 which is arranged between the discharge tray 21 and the switchback tray 22.The discharge tray 21 is formed to extend from a lower end of the vertical wall 24 upper-frontward and has a length in the front-rear direction, which is greater than or equal to a length of the main chassis 2 in the front-rear direction.", "For example, the length of the discharge tray 21 in the front-rear direction may be ⅔ of the length of the main chassis 2 in the front-rear direction.", "A rear end of the discharge tray 21 is swingably supported by the vertical wall 24 or the lateral frames 2S through a swing shaft 21A.", "Thereby, the discharge tray 21 is swingable between a closed position (see FIG.", "1) and an open position (see FIG.", "2).", "When the discharge tray 21 is in the open position, an opening 2A (see FIGS.", "2 and 3), through which the processing cartridge 6 may be attached to or detached from the main chassis 2, may be exposed.", "The vertical wall 24 is supported by the lateral frames 2S at widthwise ends thereof.", "In a position above the vertical wall 24, formed is the first outlet 24A, through which the sheet P is discharged out of the main chassis 2 (see also FIG.", "6).", "The switchback tray 22 is arranged in an upper position with respect to the discharge tray 21 to extend from an upper end of the vertical wall 24 rearward and substantially horizontally.", "The switchback tray 22 has a length in the front-rear direction, which is less than a half of the length of the main chassis 2 in the front-rear direction.", "For example, the length of the switchback tray 22 in the front-rear direction may be ⅓ of the length of the main chassis 2 in the front-rear direction.", "The switchback tray 22 is supported by the lateral frames 2S at widthwise ends thereof.", "On a front edge 22B of the switchback tray 22, arranged is a second rib 22C, which protrudes frontward from the front edge 22B, in a position to overlap the discharge tray 21 in a vertical view.", "The second rib 22C is formed at each end of the switchback tray 22 along the widthwise direction, which is an axial direction of the discharge roller 82.Each second rib 22C is formed in a triangular shape, in a plan view along the vertical direction, of which width along the widthwise direction reduces to be narrower outwardly as a corner of the triangle points frontward.", "For the shape and the arrangement of the second ribs 22C, FIG.", "9 may be referred to.", "While FIG.", "9 illustrate a perspective view of an MFD 300, which is a modified example of the MFD 1 of the present embodiment, the shape and the arrangement of the second ribs 22C may not necessarily be differed but may be similar or identical between the MFD 300 and the MFD 1.With the second ribs 22C on the front edge of the switchback tray 22, even when the sheet P is left on the discharge tray 21, and when the longer sheet P, such as the A3-sized or tabloid-sized sheet P, is exposed partly on the switchback tray 22 during double-face printing, the sheet P on the switchback tray 22 may be supported by the second ribs 22 and may be prevented from interfering with the sheet P left on the discharge tray 21.Thus, the sheet P left on the discharge tray 21 may be prevented from moved by a frontend of the sheet P being conveyed or from falling off from the discharge tray 21.The switchback tray 22 is formed to have a plurality of ribs 22A (see FIG.", "6) on one end thereof on an upstream side with regard to the conveying direction, i.e., a rear end thereof, to support the sheet P. The ribs 22A are formed to protrude upward from an upper surface of the switchback tray 22.Each of the ribs 22A includes a first part 221, of which upper edge extends horizontally along the front-rear direction, a second part 222, which extends from a front end of the first part 221 to incline downward, and a third part 223, which extends from a rear end of the first part 222 to curve downward to reach the switchback roller 92 (see also FIG.", "1).", "With the ribs 22A on the switchback tray 22, the sheet P being switched back may be supported on the ribs 22A, and friction resistance may be reduced compared to the switchback tray 22 without the ribs 22A.", "In this regard, the switchback tray 22 may not necessarily keep the sheets P discharged out of the main chassis 2 thereon but may support the sheet P temporarily when the sheet P being conveyed during double-face printing is switched back to be drawn to the duplex conveyer path.", "Each of the lateral frames 2S is formed in a shape of a rectangular box (see FIG.", "6) and arranged to extend along the front-rear direction between a position in the vicinity of the front end of the discharge tray 21 and a position in the vicinity of the rear end of the switchback tray 22 and to stand upward to be higher than the placement surface 21F of the discharge tray 21 and the placement surface 22F of the switchback tray 22.More specifically, an upper end of each lateral frame 2S is in a position higher than the L-shaped guide 93.The protrusive parts of the lateral frames 2S that protrude to be higher than the placement surface 22F are arranged on both widthwise sides of the switchback tray 22 in adjacent to the switchback tray 22 sidewise, with the switchback tray 22 interposed in there-between, and extend in the conveying direction of the sheet P, in which the sheet P may be conveyed by the switchback roller 92 toward the switchback tray 22.A protrusive height of the protrusive part in each lateral frame 2S to protrude from the placement surface 22F may be in a range between, for example, 10 mm and 100 mm or may be between 20 mm and 80 mm.", "A length of the protrusive part in the lateral frame 2S along the conveying direction in the lateral frame 2S may be in a range between 20 mm and 200 mm or may be between 40 mm and 160 mm.", "A distance between inner surfaces S1 of the lateral frames 2S along the widthwise direction at the protrusive parts higher than the discharge tray 21 and the switchback tray 22 may be substantially greater than a width of the sheet P, in particular the sheet P in a largest size usable in the MFD 1.Thus, widthwise ends of the sheet P being discharged on the discharge tray 21 or the switchback tray 22 may be restricted from skewing and falling off sideward by the inner surfaces S1 of the lateral frames 2S.", "The inner surfaces S1 of the lateral frames 2S overlap the L-shaped guide 93 in a lateral view along an axial direction of the switchback roller 92.Therefore, while a surface of the sheet P is guided by the L-shaped guide 93, the widthwise ends of the sheet P are guided by the inner surfaces S1.As shown in FIGS.", "7A and 7B, the L-shaped guide 93 includes a pivot shaft 93A, which axially extends along the widthwise direction, a pair of extended parts 93B, which extend upward in a radial direction of the pivot shaft 93A from axial ends of the pivot shaft 93A, a connector part 93C, which connects upper ends of the extended parts 93B with each other, and a comb-teeth section having a plurality of guiding parts 93D, which are arranged on the connector part 93C.", "In the following description, directions concerning the L-shaped guide 93 will be based on an orientation of the L-shaped guide 93 placed in the guiding position.", "On one of the widthwise ends of the pivot shaft 93A, disposed is a driving gear 93E, through which driving force from a drive source (not shown) such as a motor is input to the pivot shaft 93A.", "Thereby, under the control of the controller 100, the positions of the L-shaped guide 93 may be switched between the guiding position and the non-guiding position.", "As shown in FIG.", "1, the pivot shaft 93A is arranged in a lower position than an upper end of the duplex conveyer path 121 and is pivotably supported by the lateral frames 2S.", "The extended parts 93B are arranged to protrude upward from the axial ends of the pivot shaft 93A to extend through widthwise outward positions with respect to widthwise ends of a rearward one of the paired rollers in the switchback roller 92 to upper positions with respect to the switchback roller 92.The connector part 93C is arranged in an upper position with respect to the rearward one of the paired rollers in the switchback roller 92.Thus, the pivot shaft 93A, the pair of extended parts 93B, and the connector part 93C form a rectangular frame, in a front view (see FIG.", "5A).", "Thereby, the L-shaped guide 93 may be prevented from interfering with the switchback roller 92 and the duplex conveyer path 121 when pivoting between the guiding position and the non-guiding position.", "Further, when the sheet P is switched back to enter the duplex conveyer path 121, the sheet P may be conveyed through the frame formed by the pivot shaft 93A, the pair of extended parts 93B, and the connector part 93C without being interfered with by the L-shaped guide 93.As shown in FIG.", "7A, the guiding parts 93D are arranged to be spaced apart from one another along the widthwise direction on the connector part 93C in a comb-teeth arrangement.", "As shown in FIG.", "7B, each of the guiding parts 93D include an outer shell 93F, which extends upward from the connector part 93C, curves frontward, and extends frontward; and a guide rib 93G, which is formed on an inner surface of the outer shell 93F to protrude inward.", "As shown in FIG.", "7A, among the plurality of guiding parts 93D, guiding parts 93H, which are in widthwise outmost positions, are each formed to have an outer shell 93J, of which width is smaller than a width of the outer shell 93F of the other guiding parts 93D, and a guide rib 93G, which is similar to the guide rib 93G of the other guiding parts 93D.", "As shown in FIGS.", "1 and 6, a frontward part of each guiding part 93D vertically overlaps the switchback tray 22 and is in an upper position with respect to the ribs 22A.", "Meanwhile, the guide ribs 93G are arranged in alternately displaced positions with respect to the ribs 22A in the widthwise direction.", "Thereby, the sheet P may be guided by the guide ribs 93G and the ribs 22A preferably on the switchback tray 22.As shown in FIG.", "5A, the rear wall 2R of the main chassis 2 is pivotable about a lower end thereof along with the rearward one of the paired rollers in the switchback roller 92 and a part of the duplex conveyer path 121.Therefore, by pivoting the rear wall 2R along with the rearward one of the paired roller in the switchback roller 92 and the part of the duplex conveyer path 121, the sheet P, which may be jammed at the switchback roller 92 or in the duplex conveyer path 121, may be exposed to be removed.", "In the following description, directions concerning the rear wall 2R will be based on an orientation of the rear wall 2R being in the closed position, which is indicated by broken lines in FIG.", "5A.", "The rear wall 2R includes a first rear wall R1 extending vertically, a second wall R2 extending frontward from the first wall R1, a third wall R3 extending upward from a front end of the second wall R2, a fourth wall R4 which is pivotable at an upper end of the third wall R3, and a fifth wall R5 extending upper-frontward from an upper end of the fourth wall R4.The first wall R1 extends upward from a first pivot shaft R11, which is a pivot axis of the rear wall 2R.", "The second wall R2 extends from the upper end of the first wall R1 to an upper position with respect to the rearward one of the paired rollers in the switchback roller 92.The third wall R3 extends from the front end of the second wall R2 to a position in the vicinity of a bottom of the reader unit 10.In a frontward position with respect to an upper portion of the third wall R3, disposed is a sheet guide R7, which may restrict the sheet P conveyed by the switchback roller 92 toward the upper discharge tray 23 from bending frontward toward the switchback tray 22.The sheet guide R7 is arranged in a position vertically between the reader unit 10 and the switchback tray 22 to connect the lateral frames 2S with each other.", "While the sheet guide R7 is arranged to be spaced apart vertically from the guiding parts 93D of the L-shaped guide 93, a clearance, or an aperture AP, is formed at a position between the sheet guide R7 and the switchback tray 22.In other words, the sheet guide R7 forms the aperture AP so that the air may flow through the aperture AP along the front-rear direction, which is an extending direction for the inner surfaces S1 of the lateral frames 2S.", "The sheet guide R7 includes a base part R71 extending vertically, a slanted part R72 extending lower-frontward from a lower end of the base part R71, and the aperture AP formed at a lower position with respect to the slanted part R72.As shown in FIGS.", "5A and 5B, the second wall R2 and the third wall R3 are formed to have a plurality of slits R6 (see also FIG.", "6), which are formed along the front-rear direction through the rear wall 2R in positions spaced apart from one another along the widthwise direction.", "In the slits R6, the guiding parts 93D of the L-shaped guide 93 may be inserted when the L-shaped guide 93 is in the guiding position so that L-shaped guide 93 with the guiding parts 93D may be pivotable without being interfered with by the rear wall 2R.", "The slits R6 are elongated vertically so that upper ends thereof are in upper positions with respect to the guiding parts 93D of the L-shaped guide 93 in the guiding position.", "Thereby, openings are formed in the position between the reader unit 10 and the main chassis 2 through the rear wall 2R along the front-rear direction.", "Therefore, when the air flows in the space between the reader unit 10 and the main chassis 2 through a position between the front end of the discharge tray 21 and the front end of the reader unit 10, the air may flow rearward and exit through the position between the switchback tray 22 and the reader unit 10, through the positions between the guiding parts 93D and the sheet guide R2, and through the slits R6.The fourth wall R4 is connected with the upper end of the third wall R3 through the second pivot shaft R12.As shown in FIG.", "2, when the frontward part of the reader unit 10 is uplifted, the rearward part of the reader unit 10 may interfere with the fourth wall R4.However, with the pivotable structure of the fourth wall R4, the fourth wall R4 may pivot about the second pivot shaft R12 to lean rearward, and load that may be applied to the rear wall 2R from the reader unit 10 may be reduced.", "Referring back to FIGS.", "5A and 5B, in a position between the fourth wall R4 and the third wall R3, arranged is a torsion spring R8, which may urge the fourth wall R4 and the third wall R3 to align straight (FIG.", "5A).", "Thereby, the fourth wall R4, which is pressed by the reader unit 10 to pivot rearward (see FIG.", "2), may recover to an original position by the urging force from the torsion spring R8 when the reader unit 10 is placed back to the original position (see FIG.", "1).", "Meanwhile, the upper discharge tray 23 is arranged to extend substantially vertically and includes the third wall R3, the fourth wall R4, and the fifth wall R5.In other words, the upper discharge tray 23 is in an upper position with respect to the rearward one of the paired roller in the switchback roller 92 to extend upward from the upper position with respect to the rearward one of the paired roller in the switchback roller 92, with an upper portion thereof, which is the fifth wall R5, leaning frontward.", "As shown in FIG.", "3, a part of the front wall 2F of the main chassis 2 forms a manual-feeder tray unit 200, which may be detachably attached to the main chassis 2.The manual-feeder tray unit 200 includes a base 210, which may be detachably attached to the main chassis 2, a manual-feeder tray 200, which is swingable with respect to the base 210, and a manual-feeder system 230, which may feed the sheet P manually placed on the manual-feeder tray 220 to the image forming unit 4.While the manual-feeder tray unit 200 is detachable from the main chassis 2, the sheet P which may be jammed in the vicinity of the manual-feeder tray unit 200 may be removed easily.", "A printing operation to be conducted in the MFD 1 will be described below.", "Behaviors of the feeder unit 3 and the image forming unit 4 may be controlled by

the A4 size, a user may set the feeder tray 31A for the A4 size in the main chassis 2 and input a print command to the controller 100 through, for example, a personal computer (not shown) connected with the MFD 1.The controller 100, upon receiving the print command, places the switch member 110 in the first guiding position, which is indicated by the solid lines in FIG.", "1, and drives the discharge roller 82 to rotate in the normal direction.", "The sheet P in the feeder tray 31A is conveyed to the image forming unit 4 to have an image printed on one side thereof.", "The sheet P is further guided to the first discharge path 81 by the switch member 110 and discharged on the discharge tray 21.When, for another example, double-face printing is performed, i.e., when images are to be formed on both sides of the sheet P, the controller 100, upon receipt of the print command, places the switch 100 in the second guiding position, which is indicated by the broken lines in FIG.",

31A is conveyed to the image forming unit 4 to have an image printed on one side thereof and is guided by the switch member 110 to the second discharge path 91.The sheet P is conveyed in the second discharge path 91 to reach the switchback roller 92.Thereafter, the sheet P is conveyed upward by the switchback roller 92 and is bent frontward by the L-shaped guide 93 to be guided toward the switchback tray 22.In this regard, the sheet P exposed on the switchback tray 22 may be restricted at the widthwise ends thereof by the lateral frames 2S from skewing on the switchback tray 22.Thereafter, before the sheet P exits the switchback roller 92, the controller 110 drives the switchback roller 92 to rotate in the reverse direction.", "Thereby, the sheet P is guided by the lateral frames 2S at the widthwise ends thereof while being drawn back in the main chassis 2 and conveyed toward the duplex conveyer path 121.Thereafter, after the sheet P exits the switchback roller 92, the controller 100 drives the switchback roller 92 to rotate in the normal direction.", "Thereby, the sheet P conveyed through the duplex conveyer path 121 returns to the image forming unit 4, in which another image is printed on the other side thereof.", "Thereafter, the sheet P is conveyed through the second discharge path 91 to the switchback tray 22.As shown in FIG.", "4, when, for example, an image is to be formed on a single side of a sheet P2 in the A3 size, a user may set the feeder tray 31B for the A3 size in the main chassis 2 and input a print command to the controller 100 through, for example, the personal computer.", "The controller 100, upon receiving the print command, places the switch member 110 in the second guiding position, which is indicated by the broken lines in FIG.", "4, and drives the switchback roller 92 to rotate in the normal direction.", "The sheet P2 in the feeder tray 31B is conveyed to the image forming unit 4 to have an image printed on one side thereof.", "The sheet P2 is further guided to the second discharge path 91 by the switch member 110.The sheet P2 is conveyed in the second discharge path 91 to reach the switchback roller 92.Thereafter, the sheet P2 is conveyed upward by the switchback roller 92 and is bent frontward by the L-shaped guide 93 to be guided toward the switchback tray 22.When, for another example, double-face printing is performed, i.e., when images are to be formed on both sides of an A3-sized sheet, a front end of the sheet being conveyed to the switchback tray 22 may touch a desktop, a floor, or a plane, on which the MFD 1 is placed, and may be tainted.", "Meanwhile, according to the present embodiment, when images are to be printed on both sides of the A3-sized sheet P2, as shown in FIG.", "4, the rotating direction of the switchback roller 92 is switched to the reverse direction before the front end of the sheet P2 may reach the desktop.", "Therefore, the sheet P2 may be prevented from being ruined.", "For another example, when an image is to be printed on a single side of a sheet P3, which is a postcard size and may be thicker than the sheet P, the user may pull down the manual-feeder tray 220 to open.", "The user may place the sheet P3 on the manual-feeder tray 220 and input a print command to the controller 100 through, for example, the personal computer.", "The

manual-feeder tray 220 is conveyed to the image forming unit 4 to have an image printed on one side thereof and is guided by the switch member 110 to the second discharge path 91.The sheet P3 is conveyed in the second discharge path 91 to reach the switchback roller 92.Thereafter, the sheet P3 is conveyed upward by the switchback roller 92 to be discharged in the upper discharge tray 23.In this regard, the route for the sheet P3 to be conveyed from the manual-feeder tray 220 to the upper discharge tray 23 does not contain a curve with the smaller curvature radius.", "Therefore, the thicker sheet P3 may be prevented from being bent or damaged in the conveyer path.", "Meanwhile, the method to print images on the sheets may not necessarily be limited to those described above.", "For example, when double-face printing is conducted to the sheet P, the L-shaped guide 93 may be placed in the non-guiding position so that the sheet P during switchback may be supported by the upper discharge tray 23 rather than the switchback tray 22.For another example, the sheet P during switchback may be supported by either the switchback tray 22 or the upper discharge tray 23, and thereafter, the switch member 110 may be placed in the first guiding position so that the sheet P with the images printed on both sides thereof may be discharged on the discharge tray 21.According to the embodiment described above, the positions of the widthwise ends of the sheet P supported by the switchback tray 22 during switchback may be restricted by the lateral frames 2S.", "Therefore, regardless of the length of the sheet P, the sheet P may be restrained from skewing in the widthwise direction, and the sheet P may be switched back stably.", "According to the embodiment described above, further, the reader unit 10 is disposed in the upper position with respect to the switchback tray 22 and supported by the lateral frames 2S.", "Therefore, the sheet P during switchback may be concealed by the reader unit 10 from the user's sight, and, for example, the sheet P may be prevented from being erroneously touched or grabbed by the user during the switchback.", "Further, it may be prevented that the user might place an obstacle on the switchback tray 22 and that the sheet P during the switchback may be caught or jammed by the obstacle.", "According to the embodiment described above, further, the L-shaped guide 93 is arranged to overlap the lateral frames 2S in a view along the widthwise direction of the sheet P. Therefore, while the surface of the sheet P is guided by the L-shaped guide 93, the widthwise ends of the sheet P may be guided by the lateral frames 2S.", "According to the embodiment described above, further, the aperture AP is formed by the sheet guide R7, which connects the reader unit 10 and the switchback tray 22 with each other.", "Therefore, the air may flow in the position between the reader unit 10 and the switchback tray 22, and the sheet P being switched back may be cooled down while being supported on the switchback tray 22.According to the embodiment described above, further, the sheet P conveyed upward by the switchback roller 92 may be supported by the upper discharge tray 23 in the vertical posture, and the sheet P may be taken out of the upper discharge tray 23 by the user from above.", "Thus, the sheet P may be retrieved by the user easily.", "In this regard, as shown in FIG.", "4, the user may visually recognize the sheet P discharged in the upper discharge tray 23 from the front.", "According to the embodiment described above, further, the upper portion of the upper discharge tray 23 inclines frontward.", "Therefore, the sheet P being supported by the upper discharge tray 23 may lean frontward, and the user may reach the sheet P to retrieve more easily.", "According to the embodiment described above, further, the upper discharge tray 23 is formed to have the plurality of slits R6, in which the guiding parts 93D in the comb-teeth arrangement in the L-shaped guide 93 may be inserted.", "Therefore, the upper discharge tray 23 may be placed to be closer to the switchback roller 92, and the sheet P may be conveyed from the switchback roller 92 to the upper discharge tray 23 smoothly.", "Next, an example of a printer 300 (see FIGS.", "8 and 9), which is not equipped with the reader unit 10, will be described.", "In the following example, items or structures which are the same as or similar to the items or the structures

reader unit 10, are replaced with lateral frames SF.", "Each lateral frame SF may include a wall SF1, which protrudes upward from an upper surface of the lateral frame SF.", "The wall SF1 may restrict the sheet P being switched back from skewing.", "According to the printer 300 without the reader unit 10, it may be possible for the user to place an obstacle, e.g., a book, on the switchback tray 22.However, the book may be held by the L-shaped guide 93 and upper edges of the walls SL1 in a position to be floating apart from the switchback tray 22.In other words, the L-shaped guide 93 and the walls SF1 may serve as a spacer, and the obstacle may not interfere with the sheet being switched back.", "According to the printer 300 shown in FIGS.", "8 and 9, the upper discharge tray 23 may be omitted.", "If the upper discharge tray 23 is omitted, the L-shaped guide 93 may have a guiding part 931, which may replace the guiding parts 93D in the comb-teeth arrangement.", "The guiding part 931 may include an outer shell 93K, which is a plate extending in the widthwise direction, and a plurality of guide ribs 93G.", "Although examples of carrying out the invention have been described, those skilled in the art will appreciate that there are numerous variations and permutations of the image forming apparatus that fall within the spirit and scope of the invention as set forth in the appended claims.", "It is to be understood that the subject matter defined in the appended claims is not necessarily limited to the specific features or act described above.", "Rather, the specific features and acts described above are disclosed as example forms of implementing the claims.", "In the meantime, the terms used to represent the components in the above embodiment may not necessarily agree identically with the terms recited in the appended claims, but the terms used in the above embodiment may merely be regarded as examples of the claimed subject matters.", "For example, the inner surfaces S1 of the lateral frames S2 may not necessarily extend to the position to overlap the L-shaped guide 93 but may extend to reach at least the front end of the L-shaped guide 93, i.e., an exit for the sheet P formed between the L-shaped guide 93 and the switchback tray 22.With the inner surfaces S1 reaching the front side of the front end of the L-shaped guide 93, the sheet P supported on the switchback tray 22 may be restricted by the inner surfaces S1 from moving in the widthwise direction.", "For another example, the second discharge unit 9 may not necessarily be equipped with the L-shaped guide 93 or the selectable two (2) trays 22, 23.The L-shaped guide 93 may be omitted so that the sheet P may be conveyed upward solely to the upper discharge tray 23, and/or an opening, through which the sheet P is conveyed to the switchback tray 22, may be covered so that the sheet P may be guided upward to the upper discharge tray 23 rather than the switchback tray 22.For another example, the sheet P may not necessarily be paper, a postcard, or thinner paper, but may be, for example, an OHP sheet.", "For another example, the front ends of the lateral frames 2S, i.e., the downstream ends of the lateral frames 2S with regard to the conveying direction for the sheet P to be conveyed to the switchback tray 22, may not necessarily be arranged at the same or close position as the front end of the discharge tray 21.However, in order to restrict the sheet P from moving in the widthwise direction, the front ends of the lateral frames 2S may be arranged on the same side as the discharge tray 21 with regard to the discharge roller." ] ]

numerous ways, including as a process; an apparatus; a system; a composition of matter; a computer program product embodied on a computer readable storage medium; and/or a processor, such as a processor configured to execute instructions stored on and/or provided by a memory coupled to the processor.", "In this specification, these implementations, or any other form that the invention may take, may be referred to as techniques.", "In general, the order of the steps of disclosed processes may be altered within the scope of the invention.", "Unless stated otherwise, a component such as a processor or a memory described as being configured to perform a task may be implemented as a general component that is temporarily configured to perform the task at a given time or a specific component that is manufactured to perform the task.", "As used herein, the term ‘processor’ refers to one or more devices, circuits, and/or processing cores configured to process data, such as computer program instructions.", "A detailed description of one or more embodiments of the invention is provided below along with accompanying figures that illustrate the principles of the invention.", "The invention is described in connection with such embodiments, but the invention is not limited to any embodiment.", "The scope of the invention is limited only by the claims and the invention encompasses numerous alternatives, modifications and equivalents.", "Numerous specific details are set forth in the following description in order to provide a thorough understanding of the invention.", "These details are provided for the purpose of example and the invention may be practiced according to the claims without some or all of these specific details.", "For the purpose of clarity, technical material that is known in the technical fields related to the invention has not been described in detail so that the invention is not unnecessarily obscured.", "As used herein, a terminal generally refers to a device used (e.g., by a user) within a network system and used to communicate with one or more servers.", "According to various embodiments of the present disclosure, a terminal may include communication functionality.", "For example, a terminal may be a smart phone, a tablet computer, a mobile phone, a video phone, an e-book reader, a desktop Personal Computer (PC), a laptop PC, a netbook PC, a Personal Digital Assistant (PDA), a Portable Multimedia Player (PMP), an mp3 player, a mobile medical device, a camera, a wearable device (e.g., a Head-Mounted Device (HMD), electronic clothes, electronic braces, an electronic necklace, an electronic accessory, an electronic tattoo, or a smart watch), or the like.", "According to some embodiments of the present disclosure, a terminal includes a smart home appliance with communication functionality.", "A smart home appliance can be, for example, a television, a Digital Video Disk (DVD) player, an audio device, a refrigerator, an air conditioner, a vacuum cleaner, an oven, a microwave oven, a washer, a dryer, an air purifier, a set-top box, a TV box (e.g., Samsung HomeSync™, Apple TV™, or Google TV™), a gaming console, an electronic dictionary, an electronic key, a camcorder, an electronic picture frame, or the like.", "According to various embodiments of the present disclosure, a terminal can be any combination of the foregoing terminals.", "In addition, it will be apparent to one having ordinary skill in the art that a terminal according to various embodiments of the present disclosure is not limited to the foregoing terminal.", "Various embodiments of the present disclosure include a method, a device, a server, and a system of managing confidential information.", "For example, various embodiments solve the problem associated with leakage of personal buyer information in connection with an online shopping process.", "FIG.", "1 is a flowchart of a method of managing confidential information according to various embodiments of the present application.", "Referring to FIG.", "1, a process 100 for managing confidential information is provided.", "In some embodiments, process 100 is implemented by a server.", "For example, process 100 can be implemented by server 500 of FIG.", "5, mobile terminal 600 of FIG.", "6, and server 800 of FIG.", "8.Process 100 can be implemented by server 400 of FIG.", "4.In some embodiments, the target information is divided into two parts: a public part and a confidential part.", "The server sets an identifier corresponding to each confidential part of target information.", "Upon dividing the target information into the public part and the confidential part, the server stores the public part of the target information, the confidential part of the target information, and the identifier.", "The server outputs (e.g., makes public) the public part of the target information and the identifier.", "In the example shown, at 110, a confidential identifier is set.", "In some embodiments, a server sets an identifier (also referred to herein as the confidential identifier) corresponding to the confidential part of target information.", "The identifier can be a predefined alphanumeric character, a serial number, or the like.", "The target information can include confidential information that is intended to be maintained as confidential.", "For example, the target information can correspond to transaction information.", "The transaction information can be associated with an online purchase (e.g., a purchase by a buyer from an e-commerce website associated with a seller).", "The portion of the target information that corresponds to the confidential part to which the identifier is set includes personal information of the buyer (e.g., address, name, credit card information, or the like).", "The portion of target information that is not confidential information is deemed public information.", "The server can receive the target information in connection with an online transaction.", "For example, in the event that an online transaction is processed, the server can extract, or otherwise obtain, the target information from the transaction information associated with the online transaction.", "In some embodiments, part of the address of the buyer is deemed confidential and part of the address of the buyer is deemed public.", "At 120, target information is stored.", "In some embodiments, the server stores the confidential part of the target information, the public part of the target information, and the identifier corresponding to the confidential part of the target information.", "The corresponding identifier indicates the portion of the target information corresponding to the confidential information.", "At 130, the public part of the target information and the identifier is output.", "In some embodiments, the server outputs the public part of the target information and the identifier.", "The public part of the target information comprises first address information.", "In some embodiments, the server outputs the public part and the confidential identifier to a logistics company in connection with shipping or delivery of a product purchased in connection with an online transaction.", "The server can output the public part of the target information in response to an API or function call.", "For example, the server can be configured to output only the public part of the target information and the identifier (e.g., and not the confidential part of the target information).", "The server can use an application to send GPS location information or WiFi location information to a terminal.", "The public part of the target information and the identifier can be sent from the server to an application on a terminal.", "In some embodiments, the target information includes at least valid address information.", "The valid address information can be divided into two parts: first address information not to be maintained as confidential (e.g., not in need of confidentiality) and second address information to be maintained as confidential (e.g., in need of confidentiality).", "For example, the server regards the first address information as corresponding to the public part of the target information and the second address information as corresponding to the confidential part of the target information.", "In the context of online shopping, after an order is created, the shopping site's server processes the target information provided by the buyer.", "For example, the server first subjects the target information provided by the buyer to the processing according to 110 and 120 of process 100.The server can provide at least part of the target information to a logistics company in connection with delivery of a product purchased in an online transaction.", "For example, the seller takes the received target information that was output by the server (e.g., displayed in a user interface screen or printed out as a hardcopy) and the corresponding identifier and enters, or types, the target information into an express waybill for the product, which is transported by a logistics company.", "In some embodiments, the seller only receives the public part of the target information public part and the corresponding identifier.", "For example, the seller does not receive the corresponding confidential part of the target information.", "The buyer's target information is thus kept confidential vis-à-vis the seller.", "The target information can include valid address information.", "The valid address can correspond to the buyer's delivery address.", "The valid address can be divided into at least two parts: first address information and second address information (also referred to herein as the smaller-unit second address information).", "So as not to affect normal delivery by the logistics company, the smaller-unit second address information in the delivery address of each order can be regarded as a confidential part of the target information and the remaining first address information can be regarded as a public part of the target information.", "In some embodiments, only the portions of the address information required by the logistics company to deliver the package to the intended recipient are deemed as public information.", "The smaller-unit second address information corresponds to the more granular address information relative to other portions of the address information.", "As an example, the smaller-unit can be a suite number, a room number, an apartment number, a unit number, or the like.", "For example, in the case of the delivery address “xx province xx city xx district xx road xx no.", "xx building xx unit xx room,” the server can regard the smaller-unit “xx unit xx room” as a confidential part of the target information and set the corresponding identifier to “Z.” Accordingly, the server can store the public part of the target information (e.g., “xx province xx city xx district xx road xx no.", "xx building”), the confidential part of the target information (e.g., “xx unit xx room”), and the identifier Z in correspondence with each other.", "The server can output the public part of the target information (e.g., “xx province xx city xx district xx road xx no.", "xx building”) and the corresponding identifier Z.", "For example, the public part of the target information and the corresponding identifier can be output to a logistics company or the like in connection with completion of the order.", "Please note that the way in which the target information described in this paragraph is partitioned is merely one specific implementation of the present application.", "The present application is not limited to the approach described above.", "For example, in the delivery address “xx province xx city xx district xx road xx no.", "xx building xx unit xx room,” “xx road xx no.", "xx building xx unit xx room” may also be used as the confidential part of the target information and “xx province xx city xx district” as the public part of the target information.", "In another example, if the delivery address is “room xx, unit xx, building xx, no.", "xx, road xx, district xx, city xx, province xx,” “room xx, unit xx, building xx, no.", "xx” can be used as the confidential part of the target information and “road xx, district xx, city xx, province xx” can be used as the public part of the target information.", "In some embodiments, the server can store the target information in a database or table.", "The server can store the target information to include mappings of public parts of target information, confidential parts of target information, and corresponding identifiers.", "For example, the server can store the target information as shown in Table 1.TABLE 1 Target information and identifier Confidential part of target information (including Public part of target information second address (including first address information) information) Identifier Hebei Province xx city xx district xx Unit 1 Room 202 Z1 road xx no.", "xx building Guangdong Province xx city xx district Unit 1 Room 202 Z2 xx road xx no.", "xx building Beijing City, Chaoyang District, Anding Room 202 Z3 Road, Anhua Development Building Beijing City, Chaoyang District, Anding Room 420 Z4 Road, Anhua Development Building .", ".", ".", ".", ".", ".", ".", ".", ".", "Beijing City, Dongcheng District xx xx room Z7, Z8 Road xx Building Apt.", "A, No.", "123 Main Street, San Apt.", "A Z9 Francisco, CA .", ".", ".", ".", ".", ".", ".", ".", ".", "As can be seen in Table 1, each identifier can uniquely determine one piece of target information.", "As shown in Table 1, although the confidential parts of the target information corresponding to the identifiers Z1 and Z2 are the same, the corresponding public parts are different.", "Accordingly, the two target information are not the same.", "Because the two target information are not the same, the corresponding identifiers are different.", "By the same logic, although the public parts of the target information corresponding to the identifiers Z3 and Z4 are the same, the corresponding confidential parts are different.", "Thus, the target information corresponding to the identifiers Z3 and Z4 are different pieces of target information.", "In some implementations, two pieces of target information in which both the public parts and the confidential parts are the same can exist.", "For example, the target information can be the same across multiple pieces of target information in the event that two different orders by the same buyer exist.", "In some embodiments, a single identifier may be set for the two pieces of target information that have the same public parts and confidential parts.", "However, in some embodiments, in order to increase confidentiality, different identifiers are set for the two pieces of target information that have the same public parts and confidential parts.", "Correspondingly, the aforesaid two pieces of target information and the corresponding identifiers can be separately stored, or the two pieces of target information and corresponding identifiers may be merged and stored.", "For example, the target information “Beijing City, Dongcheng District xx Road xx Building xx Room” in Table 1 has two identifiers Z7 and Z8.In some embodiments, the target information includes other information in addition to the delivery address, such as buyer name, telephone number, the like, or any combination thereof.", "To protect the buyer's privacy, the aforesaid buyer name, telephone number, and other information can be regarded as confidential information.", "The buyer name, the telephone number, and other information can be deemed a confidential part of the target information.", "For example, the buyer name, the telephone number, and other information can be regarded jointly with the first address information as the confidential part of the target information.", "At 140, location information and a corresponding identifier are received.", "In some embodiments, the server receives the location information and the corresponding identifier from a mobile terminal (e.g., a mobile terminal used by a logistics company's representative).", "For example, the mobile terminal can acquire location information corresponding to the location at which the mobile terminal is currently located.", "The mobile terminal can acquire the location information of the current location of the mobile terminal using a Global Positioning Service (GPS) module, an application that is configured to determine the location of the mobile terminal according to the IP address of the mobile terminal, an application that is configured to determine the location of the mobile terminal according to the connection or signals associated with various access points, or any other known technique for obtaining the location.", "The mobile terminal sends the location information and the corresponding identifier (e.g., a to-be-recognized identifier) to the server.", "The to-be-recognized identifier is an identifier that the server can recognize (e.g., by searching a database storing mappings of identifiers and target information such as the public part of the target information or the confidential part of target information).", "The server receive the to-be-recognized identifier and can extract the appropriate information so as to recognize the identifier.", "The to-be-recognized identifier can be generated by the mobile terminal.", "For example, the to-be-recognized identifier can include a GPS position information or WiFi position information, and a mobile terminal or a user identifier that is registered with the server.", "The mobile terminal or user identifier included in the to-be-recognized data can be registered with the server such that server can identify an associated user or mobile terminal in the event that the server receives a message (e.g., the to-be-recognized identifier) including the mobile terminal or user identifier.", "The mobile terminal can acquire the identifier from logistic documentation (e.g., an express waybill).", "For example, a user can input the identifier to the mobile terminal using an application that provides an input interface (e.g., a graphical user interface).", "In some embodiments, the mobile terminal can capture an image of the logistic documentation and extract the identifier from the logistic documentation.", "In some embodiments, in the event that the logistic documentation is an electronic object such an electronic document or other file, the mobile terminal can extract the identifier from the logistic documentation.", "In some embodiments, the mobile terminal acquires the identifier using an image capture module.", "For example, the mobile terminal can use an image capture module (e.g., a camera) to capture an image of the identifier, and an application executed by the mobile terminal can process the captured image to acquire the identifier.", "In the event that the identifier is included in a QR code, a barcode, or the like, the identifier can be captured via image captured and the QR code, barcode, or the like can be processed using an application executed by the mobile terminal.", "In some embodiments, the mobile terminal can acquire the identifier as an attachment in an e-mail, a text message, an instant message, or the like.", "The identifier can be acquired over a Near Field Communication (NFC) connection, a Bluetooth connection, a WiFi connection, or the like.", "In some embodiments, the location information and the corresponding identifier can be sent in conjunction with a user identifier (e.g., an employee identifier, or the like), or the like.", "For example, the mobile terminal can send information used to authenticate the user.", "For example, the mobile terminal can be used by a logistics company representative.", "The logistics company representative can be authenticated before the location information and corresponding identifier are accepted, processed, or the like.", "The location information and the corresponding identifiers can be used in connection with completing delivery of an item (e.g., a product purchased via an online transaction).", "For example, when logistics company delivery personnel are making deliveries, the logistic company can make use of current location information and the corresponding identifiers (i.e., the to-be-recognized identifier) on the express waybill that are uploaded to the server from mobile terminals.", "A mobile terminal can be configured to use GPS positioning components of the mobile terminal to provide information acquired by the mobile terminals on the current location of the mobile terminal.", "For example, the mobile terminals can have an application installed thereon that acquires the current location of the mobile terminal (e.g., using GPS positioning components) and sends the location information to the server (contemporaneously with the corresponding identifier, waybill, the like, or any combination thereof) According to various embodiments of the present disclosure, a more granular portion of a delivery address and other confidential information associated with the delivery are not provided until a logistics company representative is within a threshold proximity (e.g., 100 meters, 10 kilometers, etc.)", "of the delivery address.", "The location of the logistics company representative can be confirmed to be within the threshold proximity of the delivery address based on the logistics company representative using a mobile terminal to send the current location of the mobile terminal to the server.", "The server can determine whether the current location of the mobile terminal is consistent with, or otherwise matches, the delivery address (e.g., the public part of the target information).", "For example, the server can determine whether the current location of the mobile terminal is within the threshold proximity of the delivery address.", "In some embodiments, the threshold proximity is configurable by a user such as a seller, a buyer, a recipient, a logistics company, or the like.", "The threshold proximity can be set according to user or business preferences, according to the type of address (e.g., residential, commercial, rural, or the like) of the delivery address, according to a jurisdiction in which the delivery address is located, the like, or any combination thereof.", "At 150, a determination is made as to whether the location information (e.g., the location information received from the mobile terminal that indicates the current location of the mobile terminal) is consistent with the first address information (e.g., the public part of the target information).", "In some embodiments, the location information can be deemed consistent with the first address information if the location information is the same as the first address information.", "In some embodiments, the location information can be deemed consistent with the first address information if the location information is in approximately the same location as the first address information (e.g., if the location information is within a threshold proximity of the first address information).", "In some embodiments, in response to the server receiving the current location information and corresponding identifier from the mobile terminal, the server determines whether the location information is consistent with the first address information.", "The server can use the identifier received from the mobile terminal in connection with the current location of the mobile terminal to look up the corresponding first address information.", "For example, the server uses the identifier to search a database or table storing mappings of first address information and identifiers for first address information mapped to the identifier.", "In the event that the server finds first address information associated with the received identifier, the server determines whether the location information received from the mobile terminal (e.g., the location information indicating the current location of the mobile terminal) matches (e.g., is the same as, or within a threshold proximity of a location corresponding to) the first address information.", "The server can determine whether the current location of the mobile terminal is the same as the first address information.", "In the event that the location information and the first address information are determined to be consistent at 150, then at 160, corresponding confidential information is sent.", "If the location information and the first address information are consistent (e.g., are the same or within a threshold proximity of each other), then the server can send the confidential part of the target information corresponding to the identifier received in connection with the location information (e.g., the to-be-recognized identifier) to the mobile terminal.", "After receiving the location information and the corresponding identifier (e.g., the to-be-recognized identifier), the server searches a local storage or a remote storage for the public part of the target information (e.g., the aforesaid first address information) corresponding to the identifier (e.g., the to-be-recognized identifier received in connection with the location information) and compares the location information with the public part of the target information.", "If the location information and the public part of the target information are the same, then the product is already within range (e.g., a threshold proximity) of the address corresponding to the first address information.", "In some embodiments, in order for the location information and the public part of the target information to be deemed the same, the location information and the public part of the target information need only be the same to a preset granularity.", "For example, the granularity can require that the location information and the public part of the target information be the same at the district level but does not require that the location information and the public part of the target information be the same at the street level.", "In addition, if the location information and the public part of the target information are the same, then it can be inferred that the person holding the mobile terminal is a delivery person for the logistics company and not another person in another area.", "At this point, the server obtains the confidential part of the target information (including the second address information) corresponding to the identifier received in connection with the location information (e.g., the to-be-recognized identifier) and sends the confidential part of the target information to the mobile terminal.", "Accordingly, the delivery person obtains the entire target information (e.g., including the valid address information formed by combining the first address information and the second address information) and thus successfully delivers the product into the hands of the buyer.", "In the event that the location information and the first address information are determined to be not consistent at 150, then at 180, an indication that the location information is not consistent with the first address information is provided.", "The server can send the indication that the current location of the mobile terminal (e.g., the location associated with the location information) is not consistent with the first address information to the mobile terminal.", "In response to receiving the indication from the server, the mobile terminal can display, or otherwise provide, the indication.", "For example, in response to receiving the indication, the mobile terminal can generate an alert and provide the alert to the user (e.g., via a vibration, a display of an icon, a text box, other prompt, an indicator LED, or the like).", "If the local information and the first address information are different, then the server does not send the confidential part of the target information to the mobile terminal.", "The server can send appropriate prompt information such as “address incorrect” to the mobile terminal.", "In some embodiments, the location information and the first address information are deemed to be different if the location information is not within the threshold proximity of the first address information.", "According to various embodiments of the

of the same digital signature scheme that was used to digitally sign the merchant security transaction code.", "For example, a public key for merchant 119 can be used to verify the digital signature and the merchant security transaction code.", "By verifying the digital signature of the merchant security transaction code, security module 125 can verify that the merchant identifier is from point-of-sale terminal 110 of merchant 119 and is accurate, which can advantageously ensure that the funding from consumer accounts 131 will be sent to an account actually associated with the merchant instead of a fraudster.", "In some embodiments, mobile application 123 can be configured to allow one-click checkout, which can be enabled by selecting a button on mobile application 123 or by placing mobile device 120 in the proximity of a data transmitter on point-of-sale terminal 110.In some embodiments, mobile application 123 can be configured to scan items and conduct transactions in real-time as items are taken from the shelf and scanned by mobile device 120 or placed within a “smart” shopping cart, such that checkout can take place in an aisle of the store, rather than at point-of-sale terminal 110.In other embodiments, checkout can take place automatically when consumer 129 exits the store of merchant 119.In a number of embodiments, mobile application 123 can receive the merchant identifier upon entering the store of merchant 119 or from a shopping cart having data transmitted in the store of merchant 119.In some embodiments, the mobile application 123 can send information from mobile device 120 to point-of-sale terminal 110, such as information regarding consumer 129, such as personally identifiable information, loyalty rewards number(s), shopping patterns, points, buying power index, and/or other suitable information.", "In several embodiments, consumer information module 114 can process the information provided from mobile application 123 to provide information to merchant 119 regarding consumer 129.In some embodiments, mobile device 120 can communicate information, such as a buying power index, to point-of-sale terminal 110 and/or merchant 119 upon entering the store of merchant 119.In several embodiments, consumer 129 can decide whether to authorize the transaction using mobile device 120.For example, mobile device 120 can ask consumer 129 to approve the transaction in mobile application 123.In a number of embodiments, mobile application 123 can present the one or more of consumer accounts 131 to consumer 129 to select which of the consumer accounts 131 to use to funds the transaction.", "In some embodiments, consumer 129 can choose to split the funding of the transaction among multiple accounts.", "For example, consumer 129 can choose to fund 20% of the transaction from a demand deposit account (e.g., a debit account) and 80% of the transaction from a non-demand deposit account (e.g., by a charge to a credit account).", "In some embodiments, if an account of the one or more of consumer accounts 131 has an account balance that is less than the amount of the transaction (or the portion of the transaction that consumer 129 has chosen to allocate to the account), loan module 126 of mobile device 120 can determine that there is a deficiency and can present an option to fund the transaction (or a portion of the transaction) using a non-demand deposit account, such as a loan account, a credit account, or a points account.", "In other embodiments, loan module 126 can present the option for funding the transaction through a non-demand deposit account even if there is no deficiency in the one or more of consumer accounts 129.In some embodiments, the loan account can be a new account that is created upon consumer 129 choosing to fund the transaction (or portion thereof) with the loan account.", "In other embodiments, the loan account can be for a previously authorized loan.", "In some embodiments, the loan account can have a pre-existing loan balance, which can be increased based on the amount of loan used to the fund the transaction.", "In several embodiments, the loan can be a small loan, and can be labeled a “micro-loan”), but can be treated the same as credit line for a loan instead of an overdraw of an account.", "In several embodiments, consumer 129 can make the decision from which account or accounts to fund the transaction, and/or to authorize a loan or a credit transaction, while at or near the point-of-sale terminal 110 in the store of merchant 119.In the same or other embodiments, loan module 126 can allow consumer 129 to choose the one or more accounts from which to fund the transaction after consumer 129 has left the store.", "In many embodiments, financial institution 130 can fund the transaction temporarily from a shadow account that the bank uses to fund overdraft transaction, which can be reimbursed from the one or more accounts selected by consumer 129.For example, consumer 129 can authorize a transaction at point-of-sale terminal 110 in the store, and financial institution 130 can authorize transfer of funds to financial institution 150 to pay merchant 119, and after consumer 129 leaves the store of merchant 129, loan module 126 can push a message to consumer 129 asking for one or more of consumer accounts 131 that consumer 129 wants to use to fund the transaction.", "The options of consumer accounts 131 can include the option to open a new loan account, or to add to the balance of an existing loan account.", "In some embodiments, consumer 129 can setup a list (e.g., prioritized list) of consumer accounts 131 to use for transaction using mobile device 120, and/or can setup before-hand an amount and/or percentage to use from one or more of the accounts.", "For example, consumer 129 can choose to use a debit account for the first $50 and then use a credit account for the rest.", "As another example, consumer 129 can choose to use a debit account for 40% of the transaction, and use a new micro-loan for the rest.", "In some embodiments, a points account can be used to pay for all or at least a portion of the payment.", "For example, consumer 129 can have a points account at financial institution 130, which can have a balance of points earned by consumer 129 at financial institution 130.In many embodiments, these points can have an exchange value, such that the points can be redeemed to pay for all or at least a portion of the payment.", "In many embodiments, after mobile device 120 has communicated with point-of-sale terminal 110 using communication module 124 to receive the merchant identifier and other transaction information, and consumer 129 has authorized the transaction, mobile device 120 can communicate with financial institution 130 and/or transaction system 140, either directly or through mobile wallet provider 160, to request a payment be made to merchant account 151 of merchant 119 from one or more of consumer accounts 131.For example, when mobile device 120 communicates with financial institution 130 (either directly or through mobile wallet provider 160) to request a payment be made, account module 134 of financial institution 130 can determine account information about merchant account 151, such as the account identifier of merchant account 151, at least partially based on the merchant identifier received from mobile device 130.In some embodiments, financial institution 130 can communicate with transaction system 140 to get the account information about merchant account 151, which can be stored in merchant account database 141.In some embodiments, financial institution 130 can save the account information about merchant account 151 so financial institution does not need to query the account information from merchant account database 141 in transaction system 140 for future transaction involving the same merchant identifier.", "In other embodiments, financial institution 130 can query for the account information from merchant account database 141 in transaction system 140 for each new transaction, or at occasional and/or regular intervals.", "In other embodiments, when mobile device 120 communicates with transaction system 140 (either directly or through mobile wallet provider 160) to request a payment be made, transaction system 140 can provide the account information about merchant account 151 to first financial institution 130.In many embodiments, having the account information about merchant account 151, financial institution 130 can initiate a payment to financial institution 150 from one or more of consumer accounts 131 to merchant account 151.In several embodiments, before initiating payment, authorization module 133 can determine whether to authorize payment from one or more of consumer accounts 131.For example, financial institution 130 can determine whether the payment amount is within the available funds in one or more of consumer accounts 131, determine whether one or more of consumer accounts 131 is currently open and in good status (or closed), authenticate the identity of consumer 129 using mobile device 120, and/or perform other actions.", "For example, in some embodiments, authentication module 121 can authenticate the identity of consumer 129, and that information can be communicated from mobile device 120 to financial institution 130.In some embodiments, mobile device 120 can prompt consumer 129 to authenticate before and/or after mobile device 120 receives the merchant identifier and/or the transaction information from point-of-sale terminal 110.In some embodiments, authorization module 133 can request additional authentication from authentication module 121 (which can be directly through a network between financial institution 130 and mobile wallet 120, or can be through mobile wallet provider 160 and/or through transaction system 140) after receiving the request for payment from mobile device 120 and/or after receiving the information about merchant 119 and/or merchant account 151.In a number of embodiments, authorization module 133 of financial institution 130 can perform different and/or varying levels of authentication based on various factors.", "For example, authentication module 121 and/or authorization module 133 can determine whether mobile device 120 used to send the request for payment has been previously used by consumer 129 for transaction with financial institution 130, whether biometrics of the consumer match stored biometrics of consumer 129, whether the requested transaction and associated details (e.g., the identity of merchant 119, the location of merchant 119, the payment amount, the one or more items to be purchased (e.g., a list of SKUs), and/or other suitable factors) are consistent with spending patterns of consumer 129, whether consumer 129 has reported mobile device 120 lost or stolen, whether consumer 129 has reported that credit cards, debit cards, or other information about one or more of consumer accounts 131 have been lost or stolen, and/or other suitable factors.", "In various embodiments, financial institution 130 can adjust the level of authentication used to verify the identity of consumer 129 based on one or more of these factors, and/or based on the payment amount, the identity of merchant 119, the location of merchant 119, historical spending of consumer 129, and/or other relevant information.", "In some embodiments, if one or more of consumer accounts 131 chosen by consumer 129 for the transaction is short on funds or otherwise cannot be fully used, loan module 135 can communicate with loan module 126 to present other funding options to consumer 129, such as the option for a micro-loan to fund all or part of the transaction, as described above.", "In many embodiments, after receiving authorization from authorization module 133, financial institution 130 can initiate a payment to financial institution 150 to transfer funds from one or more of consumer accounts 131 to merchant account 151.In a number of embodiments, the payment can be effected by sending payment information regarding a payment to be made to merchant account 151 from one or more of consumer accounts 131.In a number of embodiments, the payment information transferred from financial institution 130 to financial institution 150 can effectuate an authenticated credit push, which can irrevocably satisfy payment to the merchant and/or ensure that the merchant has good funds when consumer 129 leaves the store of merchant 119.For example, the payment can be a settlement credit push of funds for the payment amount from one or more of consumer accounts 131 to merchant account 151, which can be settled immediately.", "In various embodiments, the payment information transferred from financial institution 130 to financial institution 150 can effectuate a push promise to pay, which can provide an irrevocable guarantee of payment from financial institution 130 to financial institution 150.In several embodiments, for example, the payment can be an ACH (Automated Clearing House) credit push, which can provide an irrevocable funding guarantee.", "In many embodiments, the payment and/or the guarantee of payment can be sent in real-time from financial institution 130 to financial institution 150, which can happen for each such transaction.", "In some embodiments, the settlement of the transaction can happen later, such as in a nightly batch fashion, and in some embodiments, can happen through a different network, such as an ACH network or a credit network.", "In other embodiments, the real-time payment and/or guarantee of payment can be processed through an ACH network or a credit network.", "In some embodiments, the consumer can provide instructions to financial institution 130 to label the transaction as a debit or a credit transaction in one or more of consumer accounts 131, and in some embodiments can provide such instructions with the request to pay, or before or after the request to pay.", "In some embodiments, a credit transaction can be treated as a micro-loan, as described above.", "In certain embodiments, a debit pull with guaranteed promise to pay can be used, such that financial institution 150 can receive a guaranteed promise to pay from financial institution 130 and pull the funds using a debit pull.", "In various embodiments, transaction system 140 can store information regarding each transaction in transaction database 142.In several embodiments, transaction system 140 can serve as a central auditor for transactions between the financial institutions (e.g., 130, 150) in data communication with transaction system 142.In some embodiments, transaction system 140 can receive some or all of the information from the merchant security transaction code.", "In various embodiments, one or more portions of the merchant security transaction code can be encrypted by security module 115.For example, the merchant security transaction code can include an encrypted portion that can be decrypted by security module 146 of transaction system 140, which can be used to ensure that the message has not been tampered.", "In other embodiments, the merchant security transaction code is not encrypted, but is digitally signed, as described above, and the digital signature can be verified, in some embodiments, by security module 146, which can advantageously ensure that the merchant identifier correctly identifies merchant 119, so that the funds are paid to merchant account 151 corresponding to merchant 119.In a number of embodiments, financial institution 150, upon receiving payment and/or guarantee of payment, can notify point-of-sale terminal 110 and/or merchant 119 in real-time that merchant 119 has satisfactorily received payment from consumer 129.For example, the notification can include various information, such as the transaction identifier, the amount received in payment (or guarantee), the merchant identifier, and/or other information.", "Receiving the notice of good funds can allow merchant 119 to proceed, such as, for example, to allow consumer to leave the store of merchant 119 with the items.", "In some embodiments, for example, point-of-sale terminal 110 can match the notification to the pending transaction in point-of-sale terminal 110 using the transaction identifier.", "In certain embodiments, merchant 119 can match the notification to the point-of-sale terminal using the merchant identifier.", "In some embodiments, consumer 129 can receive a notification on mobile device 120 that the transaction has cleared, such as shown in FIG.", "22 and described below.", "In several embodiments, system 100 can advantageously provide a number of technological improvements that can overcome technological problems in conventional systems.", "For example, in several embodiments, system 100 can beneficially allow consumer 129 to send payment directly and/or immediately to merchant 119 when consumer 129 is checking out at point-of-sale terminal 110.In many embodiments, the payment systems and methods provided by system 100 described herein can eliminate the acquirer model that is conventionally used in payment card transactions.", "In several embodiments, the payment systems and methods provided by system 100 described herein can advantageously streamline payments by eliminating the need for the financial institution (i.e., the acquirer) of merchant 119 to request payment from the financial institution (i.e., the issuer) of consumer 129.For example, in many embodiments, financial institution 150 does not need to request payment from financial institution 130.In many embodiments, the payment systems and methods provided by system 100 described herein can beneficially ensure merchants (e.g., merchant 119) are paid by consumers (e.g., consumer 129) while eliminating and/or reducing many of the transaction fees paid to various entities in the conventional model.", "In a number of embodiments, the payment systems and methods provided by system 100 described herein can advantageously eliminate the chargeback liability of merchants for fraudulent transactions.", "In the conventional acquirer-issuer model, the merchant (e.g., 119) is responsible for verifying the credit or debit card to ensure that the card is not being used fraudulently.", "In several embodiments, the payment systems and methods provided by system 100 described herein can beneficially place the liability on the financial institution (e.g., 130) of the consumer (e.g.", "129), which can be in a better position (e.g., with more and/or better information) than the merchant (e.g., 119) to determine if the request to pay is a legitimate, authentic transaction requested by the consumer (e.g., 129) and/or if the consumer's account is still open and in good status (or closed), has sufficient funds, etc.", "In various embodiments, the payment systems and methods provided by system 100 described herein can advantageously allow the financial institution (e.g., 130) of the consumer (e.g., 129) to choose how to authenticate the consumer (e.g., 129), and/or can beneficially allow the financial institution (e.g., 130) of the consumer (e.g., 129) to choose the level of authentication, which can be tailored for each consumer (e.g., 129) and/or for each transaction (e.g., the financial institution (e.g., 130) can decide, at least partially based on its risk determination, that a transaction with a higher payment amount warrants a higher level of authentication).", "In several embodiments, the liability for fraudulent use of one or more of the consumer accounts (e.g., 131) can be placed on the consumer (e.g., 129), and/or the consumer (e.g., 129) can choose the level of authentication used by the financial institution (e.g., 130) of the consumer (e.g., 129).", "In many embodiments, unauthorized access to one or more of consumer accounts 131 can beneficially be reduced and/or eliminated using the payment method provided by system 100 and described herein.", "In several embodiments, the payment systems and methods provided by system 100 described herein can beneficially provide the ability for financial institution 130 to communicate directly with consumer 129 at point-of-sale 110 when making a transaction.", "In many embodiments, the payment systems and methods provided by system 100 described herein can provide information to consumer 129, such as account balance, insufficient funds, lock/freeze on one or more of consumer accounts 131, etc., in real-time before consumer 129 requests payments, which can advantageously eliminate and/or reduce negative experiences of consumer 129, such as attempting to transact with insufficient funds or a freeze on one or more of consumer accounts 131.In a number of embodiments, the payment systems and methods provided by system 100 described herein can beneficially provide consumer 129 with the ability the ability to split the payment with one or more other accounts or a new loan, such as a micro-loan, which can allow consumer 129 to successfully make the payment and reduce negative experiences of consumer 129.In some embodiments, account information about one or more of consumer accounts 131 can beneficially be better protected from theft by the payment systems and methods provided by system 100 described herein, because, in a number of embodiments, the account information of one or more of consumer accounts 131 and/or personally identifiable information of consumer 129 can be undisclosed to third parties other than financial institution 130, which maintains consumer accounts 131.For example, in some embodiments, the account information of consumer accounts 131 and/or personally identifiable information of consumer 129 can be undisclosed to point-of-sale terminal 110, merchant 119, transaction system 140, and/or financial institution 150.In many embodiments, the account identifier (e.g., account number) of consumer accounts 131 is not sent across any networks, but resides solely in financial institution 130, which can beneficially prevent that information from being stolen.", "For example, the many recent large-scale data breaches of merchant systems that have exposed consumer account information and personally identifiable information of millions of consumers could have been mitigated by using the payment systems and methods provided by system 100 and described herein.", "In other embodiments, consumer 129 can choose to provide account information of one or more of consumer accounts 131 and/or personally identifiable information of consumer 129 to one or more third parties.", "For example, in some embodiments consumer 129 can set privacy instructions in mobile device 120 and/or with financial institution 130 regarding what information can be disclosed to third parties.", "For example, consumer 129 can elect to disclose certain information to merchant 119 in order to receive discounts, point, and/or other perks from merchant 119.For example, in some embodiments, financial institution 130 can send certain personally identifiable information of consumer 129 through transaction system 140 to financial institution 150 along with the payment information, and financial institution 150 can provide the information to merchant 119.In the same or other embodiments, mobile device 120 can provide certain personally identifiable information of consumer 129 to merchant 119, such as through the wireless data communication protocol.", "Examples of such personally

example, quantization and entropy coding.", "Alternatively, the full-band core mode may be of the linear predictive type such as CELP or ACELP.", "The two BWE coding modes exemplarily illustrated in FIGS.", "1 and 2 also code a low-frequency portion using a core coding mode such as the just outlined transform coding mode or linear predictive coding mode, but this time the core coding merely relates to a low-frequency portion of the full bandwidth which ranges from 0 to fstop,Core1<fstop,Core2.The audio signal's spectral components above fstop,Core1 are parametrically coded in case of guided bandwidth extension up to a frequency fstop,BWE2, and without side information in the data stream, i.e.", "blindly, in case of blind of bandwidth extension mode between fstop,Core1 and fstop,BWE1 wherein in case of FIG.", "2, fstop,Core1<fstop,BWE1<fstop,BWE2<fstop,Core2.According to blind bandwidth extension, for example, a decoder estimates in accordance with that blind BWE coding mode, the bandwidth extension portion fstop,Core1 to fstop,BWE1 from the core coding portion extending from 0 to fstop,Core1 without any additional side information contained in the data stream in addition to the coding of the core coding's portion of the audio signal spectrum.", "Owing to the non-guided way in that the audio signal's spectrum coded up to the core coding stop frequency fstop,Core1, the width of the bandwidth extension portion of blind BWE is usually, but not necessarily smaller than the width of the bandwidth extension portion of the guided BWE mode which extends from fstop,Core1 to fstop,BWE2.In guided BWE, the audio signal is coded using the core coding mode as far as the spectral core coding portion extending from 0 to fstop,Core1 is concerned, but additional parametric side information data is provided so as to enable the decoding side to estimate the audio signal spectrum beyond the crossover frequency fstop,Core1 within the bandwidth extension portion extending from fstop,Core1 to fstop,BWE2.For example, this parametric side information comprises envelope data describing the audio signal's envelope in a spectrotemporal resolution which is coarser than the spectrotemporal resolution in which, when using transform coding, the audio signal is coded in the core coding portion using the core coding.", "For example, the decoder may replicate the spectrum within the core coding portion so as to preliminarily fill the empty audio signal's portion between fstop,Core1 and fstop,BWE2 with then shaping this pre-filled state using the transmitted envelope data.", "FIGS.", "1 and 2 reveal that switching between the exemplary coding modes may cause unpleasant, i.e.", "perceivable, artifacts at the switching instances between those coding modes.", "For example, when switching between guided BWE on the one hand and full-bandwidth coding mode on the other hand, it is clear that while the full-bandwidth coding mode correctly reconstructs, i.e.", "effectively codes, the spectral components within spectral portion fstop,BWE2 and fstop,Core2, the guided BWE mode is not even able to code anything of the audio signal within that spectral portion.", "Accordingly, switching from guided BWE to FB coding may cause a disadvantageous, sudden onset of spectral components of the audio signal within that spectral portion, and switching in the opposite direction, i.e.", "from FB core coding to guided BWE, may in turn cause a sudden vanishing of such spectral components.", "This may, however, cause artifacts in the reproduction of the audio signal.", "The spectral area where, compared to the full bandwidth core coding mode, nothing of the original audio signal's energy is preserved, is even increased in case of blind BWE and accordingly, the spectral area of sudden onset and/or sudden vanishing just described with respect to guided BWE also occurs with blind BWE and switching between that mode and FB core coding mode, with the spectral portion, however, being increased and extending from fstop,BWE1 to fstop,Core2.However, the spectral portions where annoying artifacts may result from switching between different coding modes is not restricted to those spectral portions where one of the coding modes between which a switching instance takes place is completely bare of coding anything, i.e.", "is not restricted to spectral portions outside one's of the coding modes effective coding bandwidth.", "Rather, as is shown in FIGS.", "1 and 2, there are even portions where actually both coding modes between which the switching instance takes place are actually effective, but where the energy preserving property of these coding modes differs in such a way that annoying artifacts may also result therefrom.", "For example, in case of switching between FB core coding and guided BWE, both coding modes are effective within spectral portion fstop,Core1 and fstop,BWE2, but while the FB core coding mode 20 substantially conserves the audio signal's energy within that spectral portion, the energy preserving property of guided BWE within that spectral portion is substantially decreased, and accordingly the sudden decrease/increase when switching between these two coding modes may also cause perceivable artifacts.", "The above outlined switching scenarios are merely meant to be representative.", "There are other pairs of coding modes, the switching between which causes, or may cause, annoying artifacts.", "This is true, for example, for a switching between blind BWE on the one hand and guided BWE on the other hand, or switching between any of blind BWE, guided BWE and FB coding on the one hand and the mere co-coding underlying blind BWE and guided BWE on the other hand or even between different full-band core coders with unequal energy preserving properties.", "The embodiments outlined further below overcome the negative effects resulting from the above outlined circumstances when switching between different coding modes.", "Before describing these embodiments, however, it is briefly explained with respect to FIG.", "3, which shows an exemplary encoder supporting different coding modes, how the encoder may, for example, decide on the currently used coding mode among the several coding modes supported in order to better understand why the switching therebetween may result in the above-outlined perceivable artifacts.", "The encoder shown in FIG.", "3 is generally indicated using reference sign 30, which receives an information signal, i.e.", "here an audio signal, 32 at its input and outputs a data stream 34 representing/coding the audio signal 32, at its output.", "As just outlined, the encoder 30 supports a plurality of coding modes of different energy preserving property as exemplarily outlined with respect to FIGS.", "1 and 2.The audio signal 32 may be thought of as being undistorted, such as having a represented bandwidth from 0 up to some maximum frequency such as half the sampling rate of the audio signal 32.The original audio signal's spectrum or spectrogram is shown in FIG.", "3 at 36.The audio encoder 30 switches, during encoding the audio signal 32, between different coding modes such as the ones outlined above with respect to FIGS.", "1 and 2, into data stream 34.Accordingly, the audio signal is reconstructible from data stream 34, however, with the energy preservation in the higher frequency region varying in accordance with the switching between the different coding modes.", "See, for example, the audio signal's spectrum/spectrogram as reconstructible from data stream 34 in FIG.", "3 at 38, wherein three switching instances A, B and C are exemplarily shown.", "In front of switching A, the encoder 30 uses a coding mode which encodes the audio signal 32 up to some maximum frequency fmax,cod≤fmax with substantially, for example, preserving the energy across the complete bandwidth 0 to fmax,cod.", "Between switching instances A and B, for example, the encoder 30 uses a coding mode which, as shown in 40, has an effective coded bandwidth which merely extends up to frequency f1<fmax,cod with, for example, substantially constant energy preserving property across this bandwidth, and between switching instances B and C, encoder 30 uses exemplarily a coding mode which also has an effective coded bandwidth extending up to fmax,cod, but with reduced energy preserving property relative to the full-bandwidth coding mode prior to instance A as far as the spectral range between f1 to fmax,cod, is concerned, as it is shown at 42.Accordingly, at the switching instances, problems with respect to perceivable artifacts may occur as they were discussed above with respect to FIGS.", "1 and 2.The encoder 30 may, however, despite the problems, decide to switch between the coding modes at switching instances A to C, responsive to external control signals 44.Such external control signals 44 may, for example, stem from a transmission system responsible for transmitting the data stream 34.For example, the control signals 44 may indicate to the encoder 30 an available transmission bandwidth so that the encoder 30 may have to adapt the bitrate of data stream 34 so as to meet, i.e.", "to be below or equal to, the available bitrate indicated.", "Depending on this available bitrate, however, the optimum coding mode among the available coding modes of encoder 30 may change.", "The “optimum coding mode” may be the one with the optimum/best rate to distortion ratio at the respective bitrate.", "As the available bitrate changes, however, in a manner completely or substantially uncorrelated with the content of the audio signal 32, these switching instances A to C may occur at times where the content of the audio signal has, disadvantageously, substantial energy within that high-frequency portion f1 to fmax,cod, where owing to the switching between the coding modes, the energy preserving property of encoder 30 varies in time.", "Thus, the encoder 30 may not be able to help it, but may have to switch between the coding modes as dictated from outside by the control signals 44 even at times where switching is disadvantageous.", "The embodiments described next concern embodiments for a decoder configured to appropriately reduce the negative effects resulting from the switching between coding modes at the encoder side.", "FIG.", "4 shows a decoder 50 supporting, and being switchable between, at least two coding modes so as to decode an information signal 52 from an inbound data stream 34, wherein the decoder is configured to, responsive to certain switching instances, perform temporal smoothing or blending as described further below.", "With respect to examples for coding modes supported by decoder 50, reference is made to the above description with respect to FIGS.", "1 and 2, for example.", "That is, the decoder 50 may, for example, support one or more core coding modes using which an audio signal has been coded into data stream 34 up to a certain maximum frequency using transform coding, for example, with the data stream 34 comprising, for portions of the audio signal coded with such a core coding mode, a spectral line-wise representation of a transform of the audio signal, spectrally decomposing the audio signal from 0 up to the respective maximum frequency.", "Alternatively, the core coding mode may involve predictive coding such as linear prediction coding.", "In the first case, the data stream 34 may comprise for core coded portions of the audio signal, a coding of a spectral line-wise representation of the audio signal, and the decoder 50 is configured to perform an inverse transformation onto this spectral line-wise representation, with the inverse transformation resulting in an inverse transform extending from 0 frequency to the maximum frequency so that the audio signal 52 reconstructed substantially coincides, in energy, with the original audio signal having been encoded into data stream 34 over the whole frequency band from 0 to the respective maximum frequency.", "In case of a predictive core coding mode, the decoder 50 may be configured to use linear prediction coefficients contained in the data stream 30 for temporal portions of the original audio signal having been encoded into the data stream 34 using the respective predictive core coding mode, so as to, using a synthesis filter set according to the linear prediction coefficient, or using frequency domain noise shaping (FDNS) controlled via the linear prediction coefficients, reconstruct the audio signal 52 using an excitation signal also coded for these temporal portions.", "In case of using a synthesis filter, the synthesis filter may operate in a sample rate so that the audio signal 52 is reconstructed up to the respective maximum frequency, i.e.", "at two times the maximum frequency as sample rate, and in case of using frequency domain noise shaping, the decoder 50 may be configured to obtain an excitation signal from the data stream 34 and a transform domain, the form of a spectral line-wise representation, for example, with shaping this excitation signal using FDNS (Frequency Domain Noise Shaping) by use of the linear prediction coefficients and performing an inverse transformation onto the spectrally shaped version of the spectrum represented by the transformed coefficients, and representing, in turn, the excitation.", "One or two or more such core coding modes with different maximum frequency may be available or be supported by decoder 50.Other coding modes may use BWE in order to extend the bandwidth supported by any of the core coding modes beyond the respective maximum frequency, such as blind or guided BWE.", "Guided BWE may, for example, involve SBR (spectral band replication) according to which the decoder 50 obtains a fine structure of a bandwidth extension portion, extending a core coding bandwidth towards higher frequencies, from the audio signal as reconstructed from the core coding mode, with using parametric side information so as to shape the fine structure according to this parametric side information.", "Other guided BWE coding modes are feasible as well.", "In case of blind BWE, decoder 50 may reconstruct a bandwidth extension portion extending a core coding bandwidth beyond its maximum towards higher frequencies without any explicit side information regarding that bandwidth extension portion.", "It is noted that the units at which the coding modes may change in time within the data stream may be “frames” of constant or even varying length.", "Whereever the term “frame” in the following occurs, it is thus meant to denote such a unit at which the coding mode varies in the bit stream, i.e.", "units between which the coding modes might vary and within which the coding mode does not vary.", "For example, for each frame, the data stream 34 may comprise a syntax element revealing the coding mode using which the respective frame is coded.", "Switching instances may thus be arranged at frame borders separating frames of different coding modes.", "Sometimes the term sub-frames may occur.", "Sub-frames may represent a temporal partitioning of frames into temporal sub-units at which the audio signal is, in accordance with the coding mode associated with the respective frame, coded using sub-frame specific coding parameters for the respective coding mode.", "FIG.", "4 especially concerns the switching from a coding mode having higher energy preserving property at some high-frequency spectral band, to a coding mode having less, or no, energy preserving property within that high-frequency spectral band.", "It is noted that FIG.", "4 concentrates on these switching instances merely for ease of understanding and a decoder in accordance with an embodiment of the present application should not be restricted to this possibility.", "Rather, it should be clear that a decoder in accordance with embodiments of the present application could be implemented so as to incorporate all of, or any subset of, the specific functionalities described with respect to FIG.", "4 and the following figures in connection with specific switching instances for specific coding mode pairs between which the respective switching instance taking place.", "FIG.", "4 exemplarily shows a switching instance A at time instance tA where the coding mode, using which the audio signal is coded into data stream 34, switches from a first coding mode to a second coding mode, wherein the first coding mode is exemplarily a coding mode having an effective coded bandwidth from 0 to fmax, to a coding mode coinciding in energy preserving property from 0 frequency up to a frequency f1<fmax, but having smaller energy preserving property or no energy preserving property beyond that frequency, i.e.", "between f1 to fmax.", "The two possibilities are exemplarily illustrated at 54 and 56 in FIG.", "4 for an exemplary frequency between f1 and fmax indicated with a dashed line within the schematic spectrotemporal representation of the energy preserving property using which the audio signal is coded into data stream 34 at 58.In the case of 54, the second coding mode, the decoded version of the temporal portion of the audio signal 52, succeeding the switching instance A, has an effective coded bandwidth which merely extends up to f1 so that the energy preserving property is 0 beyond this frequency as shown at 54.For example, the first coding mode as well as the second coding mode may be core coding modes having different maximum frequencies f1 and fmax.", "Alternatively, one or both of these coding modes may involve bandwidth extension with different effective coded bandwidths, one extending up to f1 and the other to fmax.", "The case of 56 illustrates the possibility of both coding modes having an effective coded bandwidth extending up to fmax, with the energy preserving property of the second coding mode, however, being decreased relative to the one of the first coding modes concerning the temporal portion preceding the time instance tA.", "The switching instance A, i.e.", "the fact that the temporal portion 60 immediately preceding the switching instance A, is coded using the first coding mode, and the temporal portion 62 immediately succeeding the switching instance A is coded using the second coding mode, may be signaled within the data stream 34, or may be otherwise signaled to the decoder 50 such that the switching instances at which decoder 50 changes the coding modes for decoding the audio signal 52 from data stream 34 is synchronized with the switching the respective coding modes at the encoding side.", "For example, the frame wise mode signaling briefly outlined above may be used by the decoder 50 so as to recognize and identify, or discriminate between different types of, switching instances.", "In any case, the decoder of FIG.", "4 is configured to perform temporal smoothing or blending at the transition between the decoded versions of the temporal portions 60 and 62 of the audio signal 52 as is schematically illustrated at 64 which seeks to illustrate the effect of performing the temporal smoothing or blending by showing that the energy preserving property within the high-frequency spectral band 66 between frequencies f1 to fmax is temporally smoothened so as to avoid the effects of the temporal discontinuity at the switching instance A.", "Similar to 54 and 56, at 68, 70, 72 and 74, a non-exhaustive set of examples show how decoder 50 achieves the temporal smoothing/blending by showing the resulting energy preserving property course, plotted over time t, for an exemplary frequency indicated with dashed lines in 64 within the high-frequency spectral band 66.While examples 68 and 72 represent possible examples of the decoder's 50 functionality for dealing with a switching instance example shown in 54, the examples shown in 70 and 74 show possible functionalities of decoder 50 in case of a switching scenario illustrated at 56.Again, in the switching scenario illustrated at 54, the second coding mode does not at all reconstruct the audio signal 52 above frequency f1.In order to perform the temporal smoothing or blending at the transition between the decoded versions of the audio signal 52 before and after the switching instance A, in accordance with the example of 68, the decoder 50 temporarily, for a temporary time period 76 immediately succeeding the switching instance A, performs blind BWE so as to estimate and fill the audio signal's spectrum above frequency f1 up to fmax.", "As shown in example 72, the decoder 50 may to this end subject the estimated spectrum within the high-frequency spectral band 66 to a temporal shaping using some fade-out function 78 so that the transition across switching instance A is even more smoothened as far as the energy preserving property within the high-frequency spectral band 66 is concerned.", "A specific example for the case of the example 72 is described further below.", "It is emphasized that the data stream 34 does not need to signal anything concerning the temporary blind BWE performance within data stream 34.Rather, the decoder 50 itself is configured to be responsive to the switching instance A so as to temporarily apply the blind BWE—with or without fade-out.", "The extension of the effective coded bandwidth of one of the coding modes adjoining each other across the switching instance beyond its upper bound towards higher frequencies using blind BWE is called temporal blending in the following.", "As will become clear from the description of FIG.", "5, it would be feasible to temporally displace/shift the blending period 76 across the switching instance so as to start even earlier than the actual switching instance.", "As far as the portion of the blending time period 76 is concerned, which would precede the switching instance A, the blending would result in reducing the audio signal's 52 energy within the high-frequency spectral band 66 in a gradual manner, i.e.", "by a factor between 0 and 1, both exclusively, or in a varying manner varying in an interval or subinterval between 0 and 1, so as to result in the temporal smoothing of the energy preserving property within the high-frequency spectral band 66.The situation of 56 differs from the situation in 54 in that the energy preserving property of both coding modes adjoining each other across the switching instance A is, in case of 56, unequal to 0 within the high-frequency spectral band 66 in both coding modes.", "In the case of 56, the energy preserving property suddenly falls at the switching instance A.", "In order to compensate for potential negative effects of this sudden reduction in energy preserving property in band 66, decoder 50 of FIG.", "4 is, in accordance with the example of 70, configured to perform temporal smoothing or blending at the transition between the temporal portions 60 and 62 immediately preceding and succeeding the switching instance A by preliminarily, for a preliminary time period 80, immediately following the switching instance A, setting the audio signal's 52 energy within the high-frequency spectral band 66 so as to be between the energy of the audio signal 52 immediately preceding the switching instance A and the energy of the audio signal within the high-frequency spectral band 66 as solely obtained using the second coding mode.", "In other words, the decoder 50, during the preliminary time period 80, preliminarily increases the audio signal's 52 energy so as to preliminarily render the energy preserving property after the switching instance A more similar to the energy preserving property of the coding mode applied immediately preceding the switching instance A.", "While the factor used for this increase may be kept constant during the preliminary time period 80 as illustrated at 70, it is illustrated at 74 in FIG.", "4 that this factor may also be gradually decreased within that time period 80, so as to obtain an even smoother transition of the energy preserving property across switching instance A within the high-frequency spectral band 64.Later on, an example for the alternative shown/illustrated in 70 will be further outlined below.", "The preliminary change of the audio signal's level, i.e.", "increase in case of 70 and 74, so as to compensate for the increased/reduced energy preserving property with which the audio signal is encoded before and after the respective switching instance A, is called temporal smoothing in the following.", "In other words, temporal smoothing within the high-frequency spectral band during the preliminary time period 80, shall denote an increase of the audio signal's 52 level/energy at the temporal portion around the switching instance A where the audio signal is coded using the coding mode having weaker energy preserving property within that high-frequency spectral band relative to the audio signal's 52 level/energy directly resulting from the decoding using the respective coding mode, and/or a decrease of the audio signal's 52 level/energy during the temporary period 80 within a temporal portion around the switching instance A where the audio signal is coded using the coding mode having higher energy preserving property within the high-frequency spectral band, relative to the energy directly resulting from encoding the audio signal with that coding mode.", "In other words, the way the decoder treats switching instances like 56 is not restricted to placing the temporary period 80 so as to directly following the switching instance A.", "Rather, the temporary period 80 may cross the switching instance A or may even precede it.", "In that case, the audio signal's 52 energy is, during the temporary period 80, as far as the temporal portion preceding the switching instance A is concerned, decreased in order to render the resulting energy preserving property more similar to the energy preserving property of the coding mode with which the audio signal is coded subsequent to the switching instance A, i.e.", "so that the resulting energy preserving property within the high-frequency spectral band lies between the energy preserving property of the coding mode before switching instance A and the energy preserving property of the coding mode subsequent to the switching instant A, both within high-frequency spectral band 66.Before proceeding with the description of the decoder of FIG.", "5, it is noted that the concepts of temporal smoothing and temporal blending may be mixed: Imagine, for example, that blind BWE is used as a basis for performing temporal blending.", "This blind BWE may have, for example, a lower energy preserving property, which “defect” may additionally compensated for by additionally applying temporal smoothing thereinafter.", "Further, FIG.", "4 shall be understood as describing embodiments for decoders incorporating/featuring one of the functionalities outlined above with respect to 68 to 74 or a combination thereof, namely responsive to respective instances 55 and/or 56.The same applies to the following figure which describes a decoder 50 which is responsive to switching instances from a coding mode having lower energy preserving property within a high-frequency spectral band 66 relative to the coding mode valid after the switching instance.", "In order to highlight the difference, the switching instance is denoted B in FIG.", "5.Where possible, the same reference signs as used in FIG.", "4 are reused in order to avoid an unnecessary repetition of the description.", "In FIG.", "5, the energy preserving property at which the audio signal is coded into stream 34 is plotted spectrotemporally in a schematic manner as it was the case in 58 in FIG.", "4, and as it is shown, the temporal portion 60 immediately preceding the switching instance B belongs to a coding mode having decreased energy preserving property within the high-frequency spectral band relative to the coding mode selected immediately after the switching instance B so as to code the temporal portion 62 of the audio signal switching the instance B.", "Again, at 92 and 94 at FIG.", "5, exemplary cases for the temporal course of the energy preserving property across the switching instance B at time instance tB are shown: 92 shows the case where the coding mode for temporal portion 60 has associated therewith an effective coded bandwidth which does not even cover the high-frequency spectral band 66 and accordingly has an energy preserving property of 0, whereas 94 shows the case where the coding mode for temporal portion 60 has an effective coded bandwidth which covers the high-frequency spectral band 66 and has a non-zero energy preserving property within the high-frequency spectral band, but reduced relative to the energy preserving property at the same frequency of the coding mode associated with the temporal portion 62 subsequent to the switching instance B.", "The decoder of FIG.", "5 is responsive to the switching instance B so as to somehow temporally smoothen the effective energy preserving property across the switching instance B as far as the high-frequency spectral band 66 is concerned, as illustrated in FIG.", "5.Like FIG.", "4, FIG.", "5 presents four examples at 98, 100, 102 and 104 as to how the functionality of decoder 50 responsive to the switching instance B could be, but it is again noted that other examples are feasible as well as will be outlined in more detail below.", "Among examples 98 to 104, examples 98 and 100 refer to the switching instance type 92, while the others refer to the switching instance type 94.Like graphs 92 and 94, the graphs shown at 98 to 104 show the temporal course of the energy preserving property for an exemplary frequency line in the inner of the high-frequency spectral band 66.However, 92 and 94 show the original energy preserving property as defined by the respective coding modes preceding and succeeding the switching instance B, while the graphs shown at 98 to 104 show the effective energy preserving property including, i.e.", "taking into account, the decoder's 50 measures performed responsive to the switching instance as described below.", "98 shows an example where the decoder 50 is configured to perform a temporal blending upon realizing switching instance B: as the energy preserving property of the coding mode valid up to the switching instance B is 0, the decoder 50 preliminarily, for a temporary period 106, decreases the energy/level of the decoded version of the audio signal 52 immediately subsequent to the switching instance B as resulting from decoding using the respective coding mode valid from switching instance B on, so that within that temporary period 106 the effective energy preserving property lies somewhere between the energy preserving property of the coding mode preceding the switching instance B, and the unmodified/original energy preserving property of the coding mode succeeding the switching instance B, as far as the high-frequency spectral band 66 is concerned.", "The example 68 uses an alternative according to which a fade-in function is used to gradually/continuously increase the factor by which the audio signal's 52 energy is scaled during the temporary time period 106 from the switching instance B to the end of period 106.As explained above, however, with respect to FIG.", "4 using examples 72 and 68, it would however also be feasible to leave the scaling factor during the temporary period 106 constant, thereby reducing, temporarily, the audio signal's energy during period 106 so as to get the resulting energy preserving property within band 66 closer to the 0 preserving property of the coding mode preceding switching instance B.", "100 shows an example for an alternative of decoder's 50 functionality upon realizing switching instance B, which was already discussed with respect to FIG.", "4 when describing 68 and 72: according to the alternative shown in 100, the temporary time period 106 is shifted along a temporal upstream direction so as to cross time instant tB.", "The decoder 50, responsive to the switching instance B, somehow fills the empty, i.e.", "zero-energy valued, high-frequency spectral band 66 of the audio signal 52 immediately preceding the switching instance B using blind BWE, for example, in order to obtain an estimation of the audio signal 52 within band 66 within that part of portion 106 which temporally precedes the switching instance B, and then applies a fade-in function so as to gradually/continuously scale, from 0 to 1, for example, the audio signal's 52 energy from the beginning to the end of period 106, thereby continuously decreasing the degree of reducing the audio signal's energy within band 66 as obtained by blind BWE prior to the switching instance B, and using the coding mode selected/valid after the switching instance B as far as the portion's 106 part succeeding the switching instance B is concerned.", "In case of switching between coding modes like in 94, the energy preserving property within band 66 is unequal to 0 both preceding as well as succeeding the switching instance B.", "The difference to the case shown at 56 in FIG.", "4 is merely that the energy preserving property within band 66 is higher within the temporal portion 62 succeeding the switching instance B, compared to the energy preserving property of the coding mode applying within the temporal portion preceding the switching instance B.", "Effectively, the decoder 50 of FIG.", "5 behaves, in accordance with the example shown at 102, similar to the case discussed above with respect to 70 and FIG.", "4: the decoder 50 slightly scales down, during a temporary period 108 immediately succeeding the switching instance B, the audio signal's energy as decoded using the coding mode valid after the switching instance B, so as to set the effective energy preserving property to lie somewhere between the original energy preserving property of the coding mode valid prior to the switching instance B

been discussed in FIG.", "4 with respect to the case 74 that a continuously temporarily changing fade-in function may be used as well.", "For completeness, 104 shows an alternative according to which decoder 50 faces/shifts the temporary period 108 in a temporal upstream direction so as to immediately precede the switching instance B with accordingly increasing the audio signal's 52 energy during that period 108 using a scaling factor so as to set the resulting energy preserving property to lie somewhere between the original/unmodified energy preserving properties of the coding mode between which the switching instance B takes place.", "Even here, some fade-in scaling function may be used instead of a constant scaling factor.", "Thus, examples 102 and 104 show two examples for performing temporal smoothing responsive to a switching instance B and just as it has been discussed with respect to FIG.", "4, the fact that the temporary period may be shifted so as to cross, or even precede,

preserving property so that below f1 no temporal smoothing is necessary and the high-frequency spectral band is placed so as to have f1 as a lower spectral bound, with f1<fmax.", "Although the coding

one embodiment, the peeling tape 121 is attached using a lamination process in which heat and pressure are applied directly to the peeling tape 121.The lamination process causes the peeling tape 121 to adhere to the micro-sensors, and temporarily to the substrate 105, while the peeling tape 121 can be removed with ease from the substrate 105 at a later time.", "Following lamination, the peeling tape 121 is cured, for example, by exposure to ultraviolet light at a low temperature that is compatible with the fluid chemical reagent 94.As shown in FIG.", "4D, the fluid chemical reagent 94

between the peeling tape 121 and the rigid substrate 105.At 112, the laminated micro-sensors can be singulated, or cut, to yield individual micro-sensors, still attached to the substrate 105.One or more of the three mask patterns used in fabrication of the micro-sensors can include scribe lines to guide singulation.", "The singulation step can be executed using a laser beam.", "At 114, the individual micro-sensors are separated from the substrate 105 to produce the completed individual flexible electrochemical micro-sensors 90.After the method 100 is complete, the rigid substrate 105 is not retained as an element of the completed micro-sensors, which are designed to be flexible.", "FIGS.", "5B and 5C illustrate one embodiment of a completed, flexible fluid electrochemical micro-sensor 90 following separation from the rigid substrate 105, wherein the peeling tape 121 now takes the place of the rigid substrate 105.Separation from the rigid substrate 105 occurs as the peeling tape 121 together with the microsensor are peeled off the rigid substrate 105 and inverted.", "The resulting individual flexible electrochemical micro-sensor 90 is shown in mirror image with

rigid substrate 105 on one side, and the peeling tape 121 on the other side.", "The chemical reagent 94, for example, an electrolyte or enzyme, thus is protected against environmental degradation during processing because it is not exposed to the environment until it is separated from the substrate 105.This can be an important advantage of the current method over other methods in which the chemical reagent 94 is exposed to humidity and temperature fluctuations during processing.", "Because many chemical reagents 94 have relatively short lifespans, without such protection they could be degraded by extreme environmental conditions present during fabrication, before the product is completed or sold.", "In the embodiments shown in FIGS.", "5C and 7B, the final sensor strip has one side with the contacts 96 and the electrodes 95 exposed along with the reagent 94.This is the condition in which the sensor strip will be inserted into the electronic circuit for use.", "In some embodiments, this is the condition in which it shipped from the distributor to the customers.", "In other embodiments, a protective backing made of an easy to remove material is a placed overlying the electrodes 95 and the reagent 94 and is peeled away just prior to use by the end user.", "For example, a paper substrate with a small amount of adhesive, a layer of tape, a support layer like wax paper or the like may be placed overlying the entire side having the contacts 96 and reagent 94 thereon to keep them clean and protected until just moments before use.", "In one embodiment, the protective cover includes a layer that is electrically conductive, such as a thin layer of tin foil, aluminum foil or the like.", "In one embodiment, the conductive layer is in contact with all the contacts 96 and shorts all the electrodes together when the product is being stored and not yet in use.", "This ensures that no stray electrical charges can build up one electrode and that all electrodes are held at the same voltage.", "This keeps the reagent active and ready while protecting it from premature degradation.", "In a further embodiment, the conductive layer is separated from the electrodes 95 and/or contacts 96 by a thin insulating layer so that the conductive layer acts as an RF shield, an electrostatic discharge (ESD) shield, and provides other protection to ensure that the electrodes 96 and the reagent 94 are properly isolated from interaction with the outside chemical and electrical environment until ready for use.", "Initiation of the peeling process from a glass carrier substrate for example, can be facilitated by submersing one end of the singulated micro-sensor in a water bath to separate the edge of the peeling tape 121 from the substrate 105.In FIG.", "5C it is clearly shown that, after peeling, at least a portion of a surface 125 of the fluid chemical reagent 94 is exposed to the ambient environment.", "Thus, if the fluid chemical reagent 94 is a liquid, the micro-sensor must be removed from the water bath prior to exposing the fluid chemical reagent 94, or the fluid chemical reagent 94 may leak out and be lost.", "Consequently, the fluid chemical reagent 94 is preferably in the form of a gel or a paste, although the fluid chemical reagent 94 alternatively can be a liquid.", "During use of the micro-sensor as a biosensor, it is advantageous for the fluid chemical reagent 94 to be exposed to the ambient environment within an organism.", "Such exposure facilitates reacting the fluid chemical reagent 94 with bodily fluids of the organism, such as blood.", "During use as an environmental micro-sensor, it is also advantageous for the fluid electrochemical micro-sensor 90 to be exposed to the ambient environment to

species inlet net 99 is desirably in the form of a conductive micromesh having dimensions selected in accordance with the viscosity of the fluid chemical reagent 94 such that a more viscous fluid chemical reagent 94 can be confined by a conductive micromesh having wider spacing.", "For example, a wider micromesh having openings about 100 microns wide may be sufficient to contain a fluid

vehicle via an intermediate transmission system.", "Further, a starter motor may be coupled to the crankshaft 40 via a flywheel to enable a starting operation of the engine 10.The combustion chamber 30 may receive intake air from an intake manifold 44 via an intake passage 42 and may exhaust combustion gases via an exhaust passage (e.g., exhaust pipe) 48.The intake manifold 44 and the exhaust passage 48 (e.g., exhaust main passage) can selectively communicate with the combustion chamber 30 via respective intake valve 52 and exhaust valve 54.In some examples, the combustion chamber 30 may include two or more intake valves and/or two or more exhaust valves.", "In this example, the intake valve 52 and exhaust valve 54 may be controlled by cam actuation via respective cam actuation

may capture exhaust particulate matter (PMs), such as ash and soot (e.g., from unburned hydrocarbons) in order to reduce vehicle emissions.", "The soot may clog the surfaces of the particulate filter thereby creating an exhaust backpressure.", "The exhaust backpressure may negatively influence the engine performance.", "Once the particulate filter 72 becomes fully loaded with soot (e.g., soot load on the particulate filter exceeds a soot load threshold), the backpressure may be too high for proper exhaust expulsion.", "Work used to expel exhaust from the engine 10 increases in order to overcome the backpressure described above.", "In order to avoid high backpressure, an engine 10 may periodically regenerate the filter either passively or actively.", "The pressure drop across the filter may measured by one or more pressure sensors 74 located at or in the vicinity of the particulate filter 72.As an example, the one or more pressure sensors may be positioned immediately upstream and immediately downstream from the particulate filter 72 within exhaust bypass passage 82.In other examples, the one or more pressure sensors may be positioned at other locations within the main exhaust passage 48 or exhaust bypass passage 82.As an example, the particulate filter may be regenerated in response to a pressure drop across the particulate filter 72 increasing above a threshold filter pressure drop.", "Passive regeneration may occur when an engine load exceeds a threshold load causing an exhaust temperature to rise.", "As the exhaust temperature increases beyond a threshold temperature (e.g., 450° C.), the soot on the particulate filter 72 may combust.", "Therefore, passive regeneration occurs without alterations to engine operations.", "Conversely, active regeneration occurs via the controller 12 signaling for alterations to engine operations in order to increase exhaust temperatures (e.g., late injection, secondary injection, throttling, exhaust recirculation, spark retard, and/or a decrease in air/fuel ratio) independent of the engine load.", "For example, the controller may send signals to a fuel injector to decrease the pulse-width of the fuel injection,

particulate filter temperature using an exhaust particulate filter heater 78 thermally coupled to the exhaust particulate filter prior to active regeneration.", "When the exhaust particulate filter is clogged the controller may send a message to the vehicle operator indicating regeneration of the exhaust particulate filter is to be conducted.", "As described above, active regeneration may include retarding the engine spark timing to increase engine air flow and subsequently increase exhaust particulate filter temperature.", "As the soot burns during either passive or active regeneration, the particulate filter temperature increases to a higher temperature (e.g., 1400° C.).", "Extended engine operation at the elevated regeneration temperature may expedite degradation of the particulate filter 72.Degradation may include the particulate filter 72 developing a leak (e.g., crack) and/or a hole, which may cause soot to escape from the filter, and flow further downstream into the exhaust

inducted into the cylinder.", "In one example, the crankshaft position sensor 118, which is also used as an engine speed sensor, may produce a predetermined number of equally spaced pulses every revolution of the crankshaft.", "The storage medium read-only memory 106 can be programmed with computer readable data representing non-transitory instructions executable by the processor 102 for

Turning now to FIG.", "6, it illustrates a timeline 600 depicting operation of an exhaust system including an exhaust diverter valve 80 and an exhaust particulate filter 72 and exhaust particulate filter heater 78 positioned in an exhaust bypass passage 82.Timeline 600 includes trend lines for engine status 604, engine temperature, Tengine 610, fuel injection flow rate, Qinj 620, exhaust particulate filter temperature, TPF 630, exhaust particulate filter pressure drop, ΔPPF 640, exhaust diverter valve position 650, exhaust particulate filter heater status 660, and exhaust particulate filter regeneration status 670.Also shown in timeline 600 are threshold engine temperature, Tengine,TH 612, threshold fuel injection flow rate, Qinj,TH 622, threshold filter temperature, TPF,TH 632, threshold filter pressure drop, and ΔPPF,TH 642.At time<time t1, the engine is OFF, Tengine is low (e.g., less than Tengine,TH), Qinj is low (less than Qinj,TH), TPF<TPH,TH, the exhaust diverter valve is positioned to bypass the exhaust particulate filter, the exhaust particulate filter heater is OFF, and the exhaust particulate filter regeneration status is OFF.", "ΔPPF is at a moderate level greater ΔPPF,TH, perhaps due to prior vehicle operation when the exhaust particulate filter was partially clogged with PM from cold start engine operation.", "At time t1, the engine is turned ON, Qinj increases above Qinj,TH and the engine temperature begins to rise, indicating fuel combustion in the engine.", "In response to the engine being ON and Tengine<Tengine,TH (e.g., cold start conditions), the controller 12 positions the exhaust diverter valve to divert exhaust gas to the exhaust particulate filter so that PM generated by combustion in the cold engine can be filtered from the exhaust passage and PM emissions can be reduced.", "Consequently, after time t1, ΔPPF begins to increase as PM is trapped within the exhaust particulate filter.", "As Tengine increases, the rate of PM generated from fuel combustion may decrease, however, the rate of increase of ΔPPF may increase in response to the higher levels of PM contained in the exhaust particulate filter.", "At time t2, Tengine increases above Tengine,TH, indicating warm engine conditions.", "In response, the controller 12 may position the exhaust diverter valve to direct the exhaust gas to bypass the exhaust particulate filter since PM generation rates from engine combustion during warm engine conditions may be very low as compared to cold start engine conditions when Tengine<Tengine,TH.", "Thus, at time t2, ΔPPF ceases to increase since no further PM is being filtered from the exhaust gas by the exhaust particulate filter 72.In response to Tengine>Tengine,TH and in response to Qinj>Qinj,TH (warm engine conditions and fuel combustion conditions), controller 12 switches the exhaust particulate filter heater ON to begin preheating the exhaust particulate filter to prepare for filter regeneration.", "As shown at time t2, TPF begins to increase responsive to the heater status 660 being switched ON.", "At time t3, Qinj decreases below Qinj,TH, indicating a DFSO or other engine shutdown event outside of engine fuel combustion conditions.", "Because TPF<TPF,TH between time t3 and time t4, the exhaust particulate filter temperature is not high enough for filter regeneration and controller 12 maintains the exhaust diverter valve positioned so that exhaust gas bypasses the exhaust particulate filter, and the PF regeneration status remains OFF.", "At time t4, TPF increases above TPF,TH, indicating that the exhaust particulate filter is preheated and ready for filter regeneration.", "In response to TPF increasing above TPF,TH, the controller switches the exhaust particulate filter heater off, as indicated by the heater status changing to OFF at time t4.Because Qinj is greater than Qinj,TH at time t4, the engine is operating within fuel combustion conditions and the controller 12 maintains the exhaust diverter valve positioned to bypass the exhaust particulate filter.", "At time t5, Qinj decreases once again below Qinj,TH indicating a DFSO or engine shutdown event outside of engine fuel combustion conditions.", "In response to the DFSO event and in response to TPF>TPF,TH and because ΔPPF>ΔPPF,TH (indicating that the filter contains a substantial level PM that can be regenerated), controller 12 may position exhaust diverter valve to direct the exhaust gas to flow from the main exhaust passage to the exhaust bypass passage 82 through exhaust particulate filter 72.Because the engine is operating outside of fuel combustion conditions at time t5, the exhaust gas may be primarily air or oxygen.", "The exhaust oxygen flowing through the preheated exhaust particulate filter may oxidize and combust the PM contained therein, thereby regenerating the exhaust particulate filter.", "Between time t5 and time t6, TPF>TPF,TH, ΔPPF>ΔPPF,TH, and Qinj increases above and decreases below Qinj,TH several times indicating periods of engine operation with and without (e.g., DFSO) fuel combustion.", "Accordingly, between times t5 and t6, responsive to when Qinj increases above Qinj,TH, the controller 12 positions exhaust diverter valve to direct exhaust gas to bypass the exhaust particulate filter and the PF regeneration status is switched OFF.", "Conversely, between times t5 and t6, responsive to when Qinj decreases below Qinj,TH, the controller 12 positions exhaust diverter valve to direct exhaust gas to flow through the exhaust particulate filter and the PF regeneration status is switched ON.", "When the PF regeneration status is switched ON, ΔPPF decreases; when the PF regeneration status is switched OFF, ΔPPF stays relatively constant since exhaust gas is bypassing the exhaust particulate filter.", "At time t6, ΔPPF decreases below ΔPPF,TH, indicating the filter regeneration is complete (e.g., PM contained in the exhaust particulate filter have been oxidized and combusted to an extent whereby the pressure drop across the filter due to PM contained therein does not adversely impact exhaust flow).", "In response, the controller 12 positions the exhaust diverter valve to direct exhaust gas to bypass the exhaust particulate filter and the PF regeneration status is switched OFF.", "Furthermore, after t6, the PF regeneration status remains off and the exhaust diverter valve remains positioned to direct exhaust gas to bypass the exhaust particulate filter even when Qinj decreases below Qinj,TH (while TPF>TPF,TH and Tengine>Tengine,TH) since ΔPPH<ΔPPF,TH.", "In this way, the exhaust particulate filter may be reliably regenerated during engine shutdown events such as DFSOs while reducing premature filter degradation.", "Furthermore, by avoiding any limiting of the engine shutdown events during filter regeneration, drivability and fuel economy may be maintained.", "Further still, by diverting the exhaust stream to the exhaust particulate filter during engine cold start conditions and bypassing the exhaust particulate filter during warm engine combustion conditions, the exhaust particulate filter size may be reduced thereby lowering manufacturing costs and improving reliability while maintaining vehicle PM emissions.", "Note that the example control and estimation routines

Mobility Proxy-Call Session Control Function according to an embodiment of the invention; and FIG.", "8 illustrates schematically in a block diagram a Mobile Switching Centre Server according to an embodiment of the invention.", "DETAILED DESCRIPTION The invention avoids the problems associated with relying on QCI values to identify the service type by providing a service type indicator that can be used for access transfer when a session is transferred.", "The following description uses an example where the type of service is a video call, although it will be appreciated that the invention can apply to other types of service, such as fax or CS data services.", "Referring to FIG.", "2 herein, when a UE 1 establishes a session (step S1) using an LTE network, a Proxy-Call Session Control Function (P-CSCF) 6 in the IMS network determines the type of service that is being used.", "Note also that step S1 can be performed in the event that a service type is changed during a session.", "For example, the same procedures apply when a voice call is upgraded to a video call.", "In step S2, the P-CSCF communicates with a Policy Charging and Rules Function (PCRF) 7 to ensure that access resources are set up for the session.", "This includes setting up suitable bearers for the media being sent during the session.", "The P-CSCF 6 may also indicate to the PCRF 7 the service being used, for example by sending an IMS Communication Service Identifier (ICSI).", "As an extension, the P-CSCF may also indicate what type of service is being used, for example a speech call, or a video call.", "This gives the PCRF 7 more information in order that it can determine how to handle the session, without requiring the PCRF to understand which ICSI maps to which service type.", "Note that there may be more than one service may be available that can be used to establish a video call, and any of these services should be capable of being transferred if a session moves from a PS to a CS access network.", "In step S3, the PCRF 7 initiates the setting up of relevant bearers for the session (e.g., a QCI=1 bearer for the speech part of the video call and a QCI=x bearer for the video part of the video call), by interacting with the PDN Gateway (PGW) or Serving gateway (SGW) 8.The PCRF 7 also indicates to the PGW/SGW 8 that the session is related to a video call by sending a service type indicator to the PGW/SGW 8 indicating the type of service, for example “service type=video call”.", "Examples of types of service that may be indicated include speech call, video call, CS data, IMS priority call or fax.", "Note that in the event that the PCRF 7 only received the communication service used from the P-CSCF 6, the PCRF 7 will need to use a local policy to map the communication service to the service type and determine the relevant service type indicator.", "In step S4, The PGW/SGW 8 interacts with a Mobility Management Entity (MME) 9 during the bearer allocation, as the MME is involved in the bearer activation/deactivation process.", "The MME is also responsible for selecting the SGW 8 and authenticating the UE and user by interacting with a Home Subscriber Server (HSS) in the IMS network.", "The PGW/SGW 8 sends the service type indicator to the MME 9.As a result, and for a video call, the MME 9 considers the bearer related to QCI=1 and QCI=x to be related to the service type indicator.", "In other words, if the service type indicator indicates that the session is a video call, the MME 9 relates QCI=1 and QCI=x to the video call.", "If there is no need to transfer the session between access networks for the duration of the session, then the service type indicator will not be used.", "However, if there is a need to transfer the session from the LTE network to a CS access network, then SRVCC is triggered, as illustrated in FIG.", "3.In step S5, an eNodeB 10 indicates to the MME 9 that the session is to be transferred to a CS network and that SRVCC is required.", "In step S6, the MME 9 has knowledge of the service type indicator for the session subject to access transfer (for example, that it is a video call), and the bearers associated with the service type indicator.", "Therefore the MME 9 handles the QCI=x bearer (for the video part of the video call) in the same way as it handles the QCI=1 bearer for PS access transfer and for suspend/resume cases during SRVCC, as described in 3GPP TS 23.216 v9.4.0.In this way, the session is identified as relating to a video call, but there is no need to use QCI=2 as proposed in TR.", "23.886 v.0.3.1 to identify the video part of the call, which allows operators more flexibility in assigning QCI values to video bearers.", "In an optional embodiment, the MME 9 may decide not to execute the service type specific SRVCC procedures and instead execute only normal SRVCC.", "In this case, the MME 9 may still handle the QCI=x bearer in the same way as the QCI=1 bearer.", "This may occur where, for example, if a network operator does not wish to support the service type specific SRVCC procedures for this subscriber.", "If configured to do so, the MME 9 indicates the type of service to the MSC Server 4 during the transfer.", "This may be done simply by forwarding the service type indicator to the MSC Server 4.This allows the MSC Server 4 to allocate resources for the video call or to invoke procedures specific to video calls.", "The MSC Server 4 performs the required actions and confirms to the MME 4 whether the service type specific SRVCC has been performed successfully, or whether only normal SRVCC has been performed.", "Normal SRVCC may be performed, for example, if the access used after the transfer does not support video call, e.g., GERAN.", "In a further embodiment of the invention, as illustrated in step S7, the network (in other words, the MSC Server 4 and the MME 9) indicates towards the UE 1 that SRVCC procedures for the specific service type is being executed, and an indication of the bearers associated with the session.", "In situations in which the network may not be able to reliably execute video SRVCC, informing the UE 1 of the SRVCC procedures ensures that the UE 1 will not attempt to execute full video SRVCC procedures in a case where the network will not allow this.", "Such cases include, for example, local policies or a temporary lack of resources.", "Referring to FIG.", "4, there is illustrated a MME 9.The MME 9 is provided with a first receiver 11 for receiving the service type indicator from the PGW/SGW 8.As described above, the service type indicator indicates the type of service being used in the session handled by the MME 9 and is associated with bearers used for the session.", "A computer readable medium in the form of a memory 12 is used to store the service type indicator.", "In the event of the session being transferred from one access type to another, a second receiver 13 receives (from the eNodeB 10) an indication that the session is to be transferred.", "A processor 14 is provided for determining the bearers associated with the session using the service type indicator, and initiating transfer of the session using those bearers.", "The MME 9 may also be provided with a first transmitter 16 for communicating with the MSC Server 4 when it is required to send an indication of the type of service to the MSC Server in order to allow the MSC Server 4 to allocate resources or invoke special procedures A second transmitter 17 may also be provided for informing the UE 1 involved in the session that SRVCC for the type of service has been invoked and an indication of the bearers associated with the session.", "The memory 12 may also be used to store a computer program 18 which, when run by the processor 14, causes the MME 9 to behave as described above.", "Turning now to FIG.", "5, there is illustrated a UE 1.The UE 1 is provided with a receiver 19 for receiving a message relating to transfer of the ongoing session from the packet switched access network to a circuit switched access from the MME 9.The message includes an indication that SRVCC for the type of service has been invoked and an indication of the bearers associated with the session.", "A processor 20 is also provided for determining further action on the basis of the indication that SRVCC for the type of service has been invoked and the indication of the bearers associated with the session.", "A computer readable medium in the form of a memory 21 may also be provided.", "This may be used to store a computer program 22 which, when run by the processor 20, cause the UE 1 to behave as described above.", "FIG.", "6 illustrates a PCRF 7.The PCRF 7 is provided with a receiver 23 for receiving from a P-CSCF 6 a message relating to setting up or upgrading of a session.", "As described above, the message includes an indication of a type of service used in the session.", "A processor 24 is provided for setting up or initializing bearers for the session and determining a service type indicator for use in a subsequent session transfer from a packet switched network to a circuit switched access network.", "This determination may either be a generation of the service type indicator or it may have been received from the P-CSCF 6.A transmitter 25 is provided for sending to the PGW/SGW 8 the service type indicator for subsequent forwarding to the MME 9.A computer readable medium in the form of a memory 25 may also be provided.", "This may be used to store a computer program 26 which, when run by the processor 24, cause the PCRF 7 to behave as described above.", "Referring to FIG.", "7, there is illustrated a P-CSCF 6, which is provided with a processor 29 for determining a type of service being used for a packet switched session.", "A transmitter 28 is provided for sending to a message to the PCRF 7, the message including an indication of the type of service being used.", "A computer readable medium in the form of a memory 29 may also be provided.", "This may be used to store a computer program 30 which, when run by the processor 27, cause the P-CSCF 6 to behave as described above.", "FIG.", "8 illustrates a MSC Server 4, which is provided with a receiver 31 for receiving from an indication of a type of service being used for a session from the MME 9.A processor 32 is provided for, on the basis of the indication, allocating resources for the session and/or invoking procedures for the session.", "A computer readable medium in the form of a memory 33 may also be provided.", "This may be used to store a computer program 34 which, when run by the processor 32, cause the MSC Server 4 to behave as described above.", "By using the procedures described above, the correct bearers will be transferred during SRVCC procedures.", "Furthermore, a UE may use multiple bearers with same QCI value without risking that the “wrong” bearer is transferred during the transfer, or restricting the usage of bearer of one type to only one.", "The procedures described above also allow the network operator to decide on the QCI values used for video calls, which gives sufficient flexibility to allow different operators to use different QCI values for video, and also different QCI values for different subscribers.", "It will be appreciated by the person of skill in the art that various modifications may be made to the above-described embodiments without departing from the scope of the present invention as described in the appended claims.", "For example, the above description refers to a LTE PS network, but the invention applies to other PS networks, for example a High Speed Packet Access (HSPA) network.", "Furthermore, the above description assumes that the type service used in the session is a video call.", "However, it will be appreciated that any type of service may be identified.", "Examples of such services include IMS priority calls, voice

"CROSS-REFERENCE TO RELATED APPLICATIONS This application claims priority to U.S.", "Provisional Application No.", "62/285,039, filed Feb. 12, 2016, the contents of which are hereby incorporated by reference herein in their entirety.", "BACKGROUND OF THE INVENTION Field of the Invention The present invention relates to tetrahydroisoquinoline derivatives or salts thereof which are useful as an active ingredient for a pharmaceutical composition, in particular, a pharmaceutical composition for treating a disease or condition responsive to modulation of the contractility of the skeletal sarcomere.", "Discussion of the Background The cytoskeleton of skeletal and cardiac muscle cells is unique compared to that of all other cells.", "It consists of a nearly crystalline array of closely packed cytoskeletal proteins called the sarcomere.", "The sarcomere is elegantly organized as an interdigitating array of thin and thick filaments.", "The thick filaments are composed of myosin, the motor protein responsible for transducing the chemical energy of ATP hydrolysis into force and directed movement.", "The thin filaments are composed of actin monomers arranged in a helical array.", "There are four regulatory proteins bound to the actin filaments, which allows the contraction to be modulated by calcium ions.", "An influx of intracellular calcium initiates muscle contraction; thick and thin filaments slide past each other driven by repetitive interactions of the myosin motor domains with the thin actin filaments.", "Of the thirteen distinct classes of myosin in human cells, the myosin-II class is responsible for contraction of skeletal, cardiac, and smooth muscle.", "This class of myosin is significantly different in amino acid composition and in overall structure from myosin in the other twelve distinct classes.", "Myosin-II forms homo-dimers resulting in two globular head domains linked together by a long alpha-helical coiled-coiled tail to form the core of the sarcomere's thick filament.", "The globular heads have a catalytic domain where the actin binding and ATPase functions of myosin take place.", "Once bound to an actin filament, the release of phosphate (cf.", "ADP-Pi to ADP) signals a change in structural conformation of the catalytic domain that in turn alters the orientation of the light-chain binding lever arm domain that extends from the globular head; this movement is termed the power stroke.", "This change in orientation of the myosin head in relationship to actin causes the thick filament of which it is a part to move with respect to the thin actin filament to which it is bound.", "Un-binding of the globular head from the actin filament (Ca2+ regulated) coupled with return of the catalytic domain and light chain to their starting conformation/orientation completes the catalytic cycle, responsible for intracellular movement and muscle contraction.", "Tropomyosin and troponin mediate the calcium effect on the interaction on actin and myosin.", "The troponin complex is comprised of three polypeptide chains: troponin C, which binds calcium ions; troponin I, which binds to actin; and troponin T, which binds to tropomyosin.", "The skeletal troponin-tropomyosin complex regulates the myosin binding sites extending over several actin units at once.", "Troponin, a complex of the three polypeptides described above, is an accessory protein that is closely associated with actin filaments in vertebrate muscle.", "The troponin complex acts in conjunction with the muscle form of tropomyosin to mediate the Ca2+ dependency of myosin ATPase activity and thereby regulate muscle contraction.", "The troponin polypeptides T, I, and C, are named for their tropomyosin binding, inhibitory, and calcium binding activities, respectively.", "Troponin T binds to tropomyosin and is believed to be responsible for positioning the troponin complex on the muscle thin filament.", "Troponin I binds to actin, and the complex formed by troponins I and T, and tropomyosin inhibits the interaction of actin and myosin.", "Skeletal troponin C is capable of binding up to four calcium molecules.", "Studies suggest that when the level of calcium in the muscle is raised, troponin C exposes a binding site for troponin I, recruiting it away from actin.", "This causes the tropomyosin molecule to shift its position as well, thereby exposing the myosin binding sites on actin and stimulating myosin ATPase activity.", "Human skeletal muscle is composed of different types of contractile fibers, classified by their myosin type and termed either slow or fast fibers.", "Table 1 summarizes the different proteins that make up these types of muscle.", "TABLE 1 Muscle Fiber Type Fast Skeletal Slow Skeletal Myosin Heavy Chain IIa, (IIb*), IIx/d Cardiac β (MHC) Troponin I (TnI) TnI fast Skeletal TnI slow Skeletal Troponin T (TnT) TnT fast Skeletal TnT slow Skeletal Troponin C (TnC) TnC fast Skeletal TnC slow/cardiac Tropomyosin (TM) TM-β/TM-α/TPM3** TM-β/TM-αs *MHC IIb is not expressed in human muscle but is present in rodents and other mammals.", "**TPM3 represents tropomyosin 3 In healthy humans, most skeletal muscles are composed of both fast and slow fibers, although the proportions of each vary with muscle type.", "Slow skeletal fibers, often called type I fibers, have more structural similarity with cardiac muscle and tend to be used more for fine and postural control.", "They usually have a greater oxidative capacity and are more resistant to fatigue with continued use.", "Fast skeletal muscle fibers, often called type II fibers, are classified into fast oxidative (Ha) and fast glycolytic (type IIx/d) fibers.", "While these muscle fibers have different myosin types, they share many components including the troponin and tropomyosin regulatory proteins.", "Fast skeletal muscle fibers tend to exert greater force but fatigue faster than slow skeletal muscle fibers and are functionally useful for acute, large scale movements such as rising from a chair or correcting falls.", "Muscle contraction and force generation is controlled through nervous stimulation by innervating motor neurons.", "Each motor neuron may innervate many (approximately 100 to 380) muscle fibers as a contractile whole, termed a motor unit.", "When a muscle is required to contract, motor neurons send stimuli as nerve impulses (action potentials) from the brain stem or spinal cord to each fiber within the motor unit.", "The contact region between nerve and muscle fibers is a specialized synapse called the neuromuscular junction (NMJ).", "Here, membrane depolarizing action potentials in the nerve are translated into an impulse in the muscle fiber through release of the neurotransmitter acetylcholine (ACh).", "ACh triggers a second action potential in the muscle that spreads rapidly along the fiber and into invaginations in the membrane, termed t-tubules.", "T-tubules are physically connected to Ca2+ stores within the sarcoplasmic reticulum (SR) of muscle via the dihydropyridine receptor (DHPR).", "Stimulation of the DHPR activates a second Ca2+ channel in the SR, the ryanodine receptor, to trigger the release of Ca2+ from stores in the SR to the muscle cytoplasm where it can interact with the troponin complex to initiate muscle contraction.", "If

region of the surface is created by a detector located in the plane of the image.", "In particular, the invention relates to so-called confocal Raman and/or fluorescence microscopy and devices for confocal fluorescence and/or Raman microscopy, without being restricted thereto.", "In addition to a device for imaging an area, especially a surface, a device is described for determining the topography of a surface that can be imaged with the assistance of confocal microscopy or confocal Raman and/or fluorescence microscopy.", "With the assistance of Raman measurements or fluorescence measurements, it is possible to excite a sample with a light source such as a laser light source, and image the chemically-different materials of the sample based on the Raman signal or fluorescence signal emitted by the sample.", "In the case of confocal microscopy, the light from the light source on the way to the sample is conducted through a lens and thereby focused on a substantially punctiform region or point of the sample surface.", "At the same time, the lens can serve to capture the light emitted by the sample, especially the emitted Raman or fluorescence light, and send it to a detector.", "With the assistance of the lens, it is also possible to confocally image a point or a substantially punctiform region of the sample substantially perpendicular to the direction of the illumination and/or detection beam path.", "If the sample, lens, or lighting is moved, it is possible to perform a scan in the x-y direction and thereby scan the entire sample.", "In confocal imaging, a substantially punctiform light source, preferably a laser light source, is projected onto a focus (Abbe condition) resulting from the wave nature of light, or a substantially punctiform region, ideally on a point of the sample.", "Subsequently, this picture element is focused preferably using the same optical system that is the same lens, on a pinhole in front of a detector.", "Instead of arranging a separate pinhole in front of the detector, it is also possible for the detector itself to be the pinhole.", "When confocal imaging is used for microscopy, the contrast of the image is substantially increased since only the focal plane of the lens contributes to the image.", "In many applications such as Raman and/or fluorescence measurements, confocal measurement possesses advantages since existing flare is strongly suppressed.", "The problem with confocal measurements or confocal microscopy is, however, that the plane or area to be imaged, especially the surface when

sample and, taking into account the values for the surface topography determined in step 1, into the confocal plane for confocal microscopy.", "This is a two-step process in which the surface topography is determined first which is followed by confocal microscopy.", "In an alternative embodiment, a value is first determined for the surface topography at a substantially punctiform region of the sample, the sample is then moved into the focal plane or confocal plane of the plane to be imaged, and then this region is imaged confocally, for example with the assistance of a confocal Raman or

is moved into the confocal plane with the additional value for the topography, the substantially punctiform region is imaged, and these steps are repeated until at least part of the plane or area, especially surface, has been scanned.", "It is particularly preferable when the values are determined for the surface topography with the assistance of a surface topography sensor, especially a non-tactile surface topography sensor, for example a confocal chromatic sensor.", "Although for example a confocal chromatic sensor was cited in the present case as the surface topography sensor, the invention is not restricted thereto.", "Surface topography sensors can be any kind of contact-free (nontactile) or contacting (tactile) sensors by means of which information can be obtained about the topography of a sample surface.", "Examples of tactile sensors are e.g.", "surface topography sensors that are termed so-called profilometers or stylus instruments.", "Examples of contact-free or non-tactile sensors are substantially optical sensors, surface topography sensors based on a white light interferometer, a triangulation sensor or a laser scanning system, or the described confocal chromatic sensor.", "A confocal chromatic sensor is distinguished in that the light is imaged at different wavelengths in different focal planes upon irradiation with white light.", "If the reflected light imaged in different focal planes is imaged on a spectrometer through a pinhole and evaluated with the assistance of a spectrometer, the distance e.g.", "from the confocal chromatic sensor to the surface of the sample can for example be determined from this signal, and the surface topography can be determined thereby.", "The fact is exploited that the wavelength of the focal plane in which the sample surface is located manifests a maximum intensity in a spectrometer.", "Each wavelength in the spectrometer can therefore be assigned a sample distance.", "With the assistance of the confocal chromatic sensor, it is therefore possible to quickly and directly determine the topography of the sample purely by optical means.", "The confocal chromatic sensor makes it possible to optically determine the sample surface topography and hence scan samples and confocally image the sample surface even when the topography is not sufficiently flat.", "It is possible to track the focal plane or

microscope in particular, it can be provided that a spectrometer spectrally decomposes the light which is emitted from the sample, i.e., the Raman or fluorescence light.", "Such a spectral decomposition can be performed in the spectrometer, for example, using a grating or a prism.", "If the light thus decomposed is recorded using a CCD camera, it is thus possible to record a complete spectrum of the Raman or fluorescence light scattered by the sample.", "The advantage of the spectral decomposition of the Raman light in a Raman microscope is that, for example, by rotating the grating in the spectrometer, an arbitrary spectral range can be selected for the detector for measurement.", "The device, in particular the confocal microscope, preferably the confocal Raman and/or confocal fluorescence microscope, can have a movable sample table, which enables the sample surface to be imaged by moving the sample, for example.", "Alternatively or additionally, the objective lens or the microscope itself can also be moved to obtain an image of the sample.", "It is also possible to record spatial maps of spectral properties of the sample.", "A very high depth resolution is achieved in particular using confocal imaging.", "The mobility of the sample table in the x/y direction enables scanning of the sample or a sample region.", "With the aid of the second light source and in particular in combination with the electrically focusable lens, according to the invention, the focal plane of the second light source can be brought by means of separately controllable focal position into/onto the surface of the sample.", "The topography of the sample for readjusting the focal plane of the first light source for the Raman microscopy is ascertained from the control signal of the controllable focal position.", "This control/regulation enables the sample surface to be kept continuously in the confocal plane for the confocal Raman microscopy during scanning.", "For this purpose, the X-Y scan of the sample is expanded to an X-Y-Z scan, wherein the Z scan is used to compensate for the sample topography.", "In contrast to the first aspect of the invention, it is not necessary for the control/regulation in the method according to the invention to firstly record the surface topography, in order to then track the sample plane in the focus, rather the continuous determination of the focal position with the aid of the second light source enables the simultaneous bringing of the sample into the focal plane of the objective lens for the confocal Raman and/or fluorescence microscopy." ], [ "RELATED APPLICATION DATA The present application is a continuation-in-part of U.S. patent application Ser.", "No.", "13/580,324 which was filed on Aug. 21, 2012 and

generally relates to the field of imaging.", "In particular, the present invention is directed to a device for imaging a sample surface.", "BACKGROUND In many applications such as Raman and/or fluorescence measurements, confocal measurement possesses advantages since existing flare is strongly suppressed.", "The problem with confocal measurements or confocal microscopy is, however, that the plane or area to be imaged, especially the surface when scanning a sample, does not remain within the focal plane due to drift, sample unevenness, roughness, and tilt of the sample.", "SUMMARY OF THE DISCLOSURE The invention relates to a device and a method for imaging an area, especially the surface of a sample, in particular a sample having a topography by a scanning a plurality of regions, especially substantially punctiform regions with the assistance of confocal microscopy.", "In confocal microscopy, a confocal image of the substantially punctiform region of the surface is created by a detector located in the plane of the image.", "In particular, the invention relates to so-called confocal Raman and/or fluorescence microscopy and devices for confocal fluorescence and/or Raman microscopy, without being restricted thereto.", "In addition to a device for imaging an area, especially a surface, a device is described for determining the topography of a surface that can be imaged with the assistance of confocal microscopy or confocal Raman and/or fluorescence microscopy.", "With the assistance of Raman measurements or fluorescence measurements, it is possible to excite a sample with a light source such as a laser light source, and image the chemically-different materials of the sample based on the Raman signal or fluorescence signal emitted by the sample.", "In the case of confocal microscopy, the light from the light source on the way to the sample is conducted through a lens and thereby focused on a substantially punctiform region or point of the sample surface.", "At the same time, the lens can serve to capture the light emitted by the sample, especially the emitted Raman or fluorescence light, and send it to a detector.", "With the assistance of the lens, it is also possible to confocally image a point or a substantially punctiform region of the sample substantially perpendicular to the direction of the illumination and/or detection beam path.", "If the sample, lens, or lighting is moved, it is possible to perform a scan in the x-y direction and thereby scan the entire sample.", "In confocal imaging, a substantially punctiform light source, preferably a laser light source, is projected onto a focus (Abbe condition) resulting from the wave nature of light, or a substantially punctiform region, ideally on a point of the sample.", "Subsequently, this picture element is focused preferably using the same optical system that is the same lens, on a pinhole in front of a detector.", "Instead of arranging a separate pinhole in front of the detector, it is also possible for the detector itself to be the pinhole.", "When confocal imaging is used for microscopy, the contrast of the image is substantially increased since only the focal plane of the lens contributes to the image.", "In many applications such as Raman and/or fluorescence measurements, confocal measurement possesses advantages since existing flare is strongly suppressed.", "The problem with confocal measurements or confocal microscopy is, however, that the plane or area to be imaged, especially the surface when scanning a sample, does not remain within the focal plane due to drift, sample unevenness, roughness, and tilt of the sample.", "In regard to confocal light microscopy, reference is made to DE 199 02 234 A1 in which a microscope with a confocal lens is described in detail.", "A confocal Raman and/or fluorescence microscope is known from DE 102009015945 A1.An AFM microscope or STM microscope is known from U.S. Pat.", "No.", "5,581,082 that is combined with a confocal microscope.", "The sample can be scanned with the AFM tip, particularly in the z direction, using the microscope known from U.S. Pat.", "No.", "5,581,082.Depth information is obtained with the assistance of the AFM tip in U.S. Pat.", "No.", "5,581,082.During AFM measurement, in particular AFM topography measurement, optical signals are also recorded, thus allowing the topographic data obtained from AFM topography measurement to be correlated with the optical data.", "In U.S. Pat.", "No.", "5,581,082, confocal measurement is always performed simultaneous to topographic measurement.", "A disadvantage of U.S. Pat.", "No.", "5,581,082 is the reduced scanning range which lies within a range of 100 μm to a maximum of 300 μm in the x-y plane.", "Furthermore, the AFM tip can only provide a maximum range of 5-10 μm of depth information in the z direction.", "A further disadvantage is that the AFM tip blocks light from the sample.", "A further disadvantage is that the method is not contact free.", "U.S. Pat.", "No.", "5,581,082 therefore does not permit measurements of samples in the >300 μm range and with a roughness >10 μm.", "The problem with confocal microscopy, especially confocal microscopy and/or fluorescence microscopy of surfaces, especially of larger sample areas, especially >300 μm and of technical surfaces, is that imaging is very difficult since there is frequently an insufficient area of sample topography.", "When scanning in a given plane, a so-called X-Y scan, the sample surface continuously leaves the focal plane of the microscope, making it impossible to easily and completely image the sample surface or the sample.", "The object of the invention is therefore to present a device by means of which the disadvantages of the prior art can be avoided.", "In particular, the invention makes it possible to confocally image a plane or area, especially a surface of a sample, i.e.", "with the assistance of confocal microscopy.", "This is also possible with samples having an insufficient flat sample topography, for example a curved sample.", "According to the invention, this object is achieved in a first aspect of the invention in that a device for imaging a plane or area, especially a sample surface with a topography using confocal microscopy, especially confocal Raman or fluorescence microscopy is provided, wherein values for the topography of the surface are determined with the aid of a surface topography sensor, preferably a non-tactile surface sensor and, with the aid of the surface topography values, the area to be imaged, especially the surface, is brought into the confocal plane during scanning for confocal microscopy, especially Raman and/or fluorescence microscopy.", "Determining the surface topography according to the invention, preferably with a nontactile sensor, makes it possible to remain on the surface in a subsequent Raman measurement or to measure a specific depth.", "In a first embodiment of the invention (two-step method), the measured topography is saved, processed and then traced.", "In a second embodiment of the invention, a control system is used to keep the sample in focus (or a plane parallel thereto) (one-step method).", "The plane or area, especially surface, is imaged by means of confocal microscopy, especially Raman and/or fluorescence microscopy by scanning a plurality of substantially punctiform regions of the plane or area, especially a surface, with a device for confocally imaging the substantially punctiform region of the plane or area, especially surface, and a focal plane on a detector.", "As described above, the sample can be kept in the confocal plane or focal plane in two ways when the values of the surface topography are known.", "In a first embodiment of the invention (two-step method), first the part of the sample to be imaged is scanned, and the values of the surface topography are recorded and then imaged taking into account the surface topography of a sample plane.", "The values of the surface topography are then used in this device to move the sample such that the plane to be imaged remains in the focal plane of the confocal microscope when scanning the sample with the assistance of the confocal microscope, especially a confocal Raman or fluorescence microscope, independent of the unevenness or curvature of the sample.", "In the present application, that which is understood to be the topography of a surface or a sample topography in the current application will be described as a nonexclusive example with reference to a confocal Raman microscope having a confocal chromatic sensor.", "The sample topography for such an arrangement having a confocal chromatic sensor is understood to be sample units greater than 1 nm, especially greater than 10 nm, and preferably greater than 100 nm.", "To be understood as roughness in the present application is sample unevenness substantially in the z direction that cannot be resolved especially due to the lateral extension of the light spot of the confocal chromatic sensor.", "With a Raman microscope having a confocal chromatic sensor, this would be for example a surface roughness substantially in the z direction of for example less than 100 nm, preferably less than 10 nm and especially less than 1 nm, that is, the sub-μm range.", "When imaging a plane, the values of the surface topography can be determined in a first step for a plurality of substantially punctiform regions of the sample, and the surface topography of the sample can be determined therefrom and, in a second step, the sample is moved into the plurality of substantially punctiform regions of the sample and, taking into account the values for the surface topography determined in step 1, into the confocal plane for confocal microscopy.", "This is a two-step process in which the surface topography is determined first which is followed by confocal microscopy.", "In an alternative embodiment, a value is first determined for the surface topography at a substantially punctiform region of the sample, the sample is then moved into the focal plane or confocal plane of the plane to be imaged, and then this region is imaged confocally, for example with the assistance of a confocal Raman or fluorescence microscope.", "The entire sample can be scanned in this manner.", "This type of device is characterized in that: The sample is the first moved to a substantially punctiform region while scanning, a value is determined for the surface topography, and the sample is moved into the confocal plane with the value for the topography, and the substantially punctiform region is imaged; After imaging the substantially punctiform region, the sample is moved to another substantially punctiform region in a second step, another value for the surface topography is determined there, the sample is moved into the confocal plane with the additional value for the topography, the substantially punctiform region is imaged, and these steps are repeated until at least part of the plane or area, especially surface, has been scanned.", "It is particularly preferable when the values are determined for the surface topography with the assistance of a surface topography sensor, especially a non-tactile surface topography sensor, for example a confocal chromatic sensor.", "Although for example a confocal chromatic sensor was cited in the present case as the surface topography sensor, the invention is not restricted thereto.", "Surface topography sensors can be any kind of contact-free (nontactile) or contacting (tactile) sensors by means of which information can be obtained about the topography of a sample surface.", "Examples of tactile sensors are e.g.", "surface topography sensors that are termed so-called profilometers or stylus instruments.", "Examples of contact-free or non-tactile sensors are substantially optical sensors, surface topography sensors based on a white light interferometer, a triangulation sensor or a laser scanning system, or the described confocal chromatic sensor.", "A confocal chromatic sensor is distinguished in that the light is imaged at different wavelengths in different focal planes upon irradiation with white light.", "If the reflected light imaged in different focal planes is imaged on a spectrometer through a pinhole and evaluated with the assistance of a spectrometer, the distance e.g.", "from the confocal chromatic sensor to the surface of the sample can for example be determined from this signal, and the surface topography can be determined thereby.", "The fact is exploited that the wavelength of the focal plane in which the sample surface is located manifests a maximum intensity in a spectrometer.", "Each wavelength in the spectrometer can therefore be assigned a sample distance.", "With the assistance of the confocal chromatic sensor, it is therefore possible to quickly and directly determine the topography of the sample purely by optical means.", "The confocal chromatic sensor makes it possible to optically determine the sample surface topography and hence scan samples and confocally image the sample surface even when the topography is not sufficiently flat.", "It is possible to track the focal plane or confocal plane and thereby use confocal Raman microscopy even when the sample topography is distinct, i.e., not flat, with the assistance of the confocal chromatic sensor, for example using a Raman microscope.", "In one particular embodiment, a position signal of the surface topography sensor is used to control the confocal plane or focal plane.", "It is particularly preferable for the confocal chromatic sensor to comprise an optical system, especially a lens system having a large chromatic error.", "With a lens system, a chromatic error or chromatic aberration is understood to be an error that is caused by the wavelength dependency of the refraction index of the material used for the lenses.", "Instead of using lenses as the optical component to generate a large chromatic error, diffractive components can be used as the confocal chromatic sensor.", "Given the wavelength dependency of the diffraction index of the glass of the refractive component, the focal length also depends on the wavelength, that is, the confocal plane lies at different locations for different wavelengths.", "In regard to confocal chromatic sensors, reference is made to the confocal chromatic sensors of Micro-Epsilon Messtechnik GmbH & Co. KG, Königsbacher Straße 15, 94496 Ortenburg, Germany (www.micro-epsilon.de), the entire content disclosed by the website being included in the application.", "Confocal chromatic sensors are particularly suitable for measuring distance with a resolution within a range greater than 1 nm to 1 μm, preferably greater than 1 nm to 100 nm, since they do not have to be refocused due to their high measuring precision and simultaneous large measuring range that extends for example from 100 μm to 40 mm, especially from 120 μm to 21 mm, and most preferably from 40 μm to 12 mm.", "The size of the light spot in the x-y plane preferably ranges from 0.1 μm to 1 mm, preferably 7 μm to 150 μm, in particular 10 μm to 100 μm, depending on the measuring range, and it has large working distance of greater than 100 μm to 200 mm depending on the sensor.", "As described above with reference to the first device, the sample surface can first be measured in a two-step process with a confocal chromatic sensor, and then this topography can be traced in a confocal optical measurement, for example with confocal Raman microscopy.", "A predetermined plane of a sample such as the surface can thereby be confocally imaged.", "The light of a non-monochromatic, preferably broadband light source is guided through the refractive lens system of the confocal chromatic sensor as a light spot to the substantially punctiform region of the sample surface where it is reflected by the sample, and collected and evaluated with the assistance of a spectrometer, and the wavelength with the focal plane in which the sample surface lies manifests a maximum intensity in the spectrum.", "The non-monochromatic, preferably broadband light source is preferably a white light source, that is, a broadband light source within the visible wavelength range.", "Broadband light sources would also be possible that do not emit visible light, for example in the IR wavelength range, or in the ultraviolet wavelength range.", "Illuminating the sample surface in this way would make it possible to decouple the beam paths from the confocal chromatic sensor and e.g.", "Raman microscope and use the same lens for the chromatic sensor and for the Raman measurements using the Raman microscope.", "This makes it possible to determine the distance from the sensor to the sample surface with the assistance of the spectrometer since each wavelength can be assigned precisely one sample distance.", "In addition to determining the values of the surface topography with the assistance of a confocal chromatic sensor, other options are also conceivable.", "For example, it would also be possible not to determine the surface topography with the assistance of a confocal chromatic sensor; instead, the sample could also be periodically moved e.g.", "in the z direction.", "The sample would therefore be periodically moved through the focus in the z direction.", "By periodically moving the sample, an average in the direction perpendicular to the sample surface, i.e., in the z direction, can be obtained and hence an increasingly sharper image of the sample surface with a relatively even intensity.", "This device has also been termed an extended focus device.", "It is however necessary to adapt the modulation depth of the movement to the roughness or topography of the sample.", "Moving the sample to determine the focus as described above, so-called extended focus measurement, can also be combined with automatic focus tracking.", "The center of the modulation, i.e.", "the periodic movement, is tracked in the z direction so that an excessively large modulation depth does not have to be chosen for very rough samples.", "The fact is exploited that the focus of the light source moves through the surface during modulation.", "The signal that is detected is similar to a Gaussian curve with the location of its maximum corresponding to the ideal focus on the surface.", "If the position of maximum intensity is sent to a controller, the center of the modulation can be tracked.", "The topography of the sample can be determined by using this type of measurement since the maximum intensity of the modulated signal corresponds to the sample topography.", "The movement of the sample in the z direction to compensate for surface roughness can also be superimposed on the tracking of the sample with reference to the surface topography determined with the assistance of a confocal chromatic sensor.", "Combining both devices allows the surface topography of a sample to be taken into account and simultaneously compensate for surface roughness.", "An example of such tracking is shown in detail in FIG.", "6 of the application.", "Reference is made to the description therein.", "It is particularly preferable for the confocal Raman microscope and/or fluorescence microscope to comprise a light source to excite light emission in the sample, as well as a detector to detect the photons emitted by the light emission, in particular the emitted Raman and/or fluorescence photons.", "In addition to this device, the invention also makes available a device for imaging the surface of the sample by scanning a plurality of substantially punctiform regions of the surface, comprising an apparatus for confocally imaging the substantially punctiform region of the surface in a focal plane on a detector, wherein the device preferably has a surface topography sensor.", "In one embodiment, the surface topography sensor can be an independent apparatus.", "This is however not essential to the invention.", "Any type of sensor is suitable as the surface topography sensor by means of which it is possible to measure the surface topography, i.e., the deviation, e.g.", "of a sample surface, from the sample plane in the direction perpendicular to the sample surface, i.e.", "in the z direction.", "Such surface topography sensors can be both contact-free and non-contact free, i.e., tactile, surface topography sensors.", "Examples of tactile surface topography sensors are mechanical profilometers, AtomicForce microscopes (AFM microscope), for example, the AFM microscope alpha 300 A by WiTec GmbH or stylus instruments.", "Examples of contact-free surface topographies are in particular optical sensors such as white light interferometers, triangulation sensors, laser scanning systems that for example use confocal microscopy, and confocal chromatic sensors.", "Also optical coherence tomography would be an alternative method.", "When the surface topography sensor is an optical sensor, it has an independent beam path in a first embodiment next to the apparatus for confocally imaging the substantially punctiform region of the surface.", "In a second embodiment of the invention, the excitation focus of the laser for the Raman measurement is guided through the same lens as the excitation focus of the surface topography sensor.", "In a preferred embodiment of the invention, the light of the confocal Raman and/or fluorescence microscope lies within a first wavelength range and the light of the confocal chromatic sensor lies in a second wavelength range, and it is particularly preferable when the first and second wavelength range do not overlap.", "When the wavelength ranges do not overlap, they are preferably selected so that the first wavelength range is defined by the limits of the emitted luminescence spectrum and/or Raman spectrum of the quantity to be investigated, and the second wavelength lies above or below the first wavelength range without overlapping the first wavelength range.", "For example, the first wavelength range for the emitted luminescence or Raman spectrum of the sample to be investigated can lie within a range of 500 nm to 1100 nm, and especially 532 nm to 650 nm.", "The second wavelength range extends from 350 nm to 500 nm, and preferably from 400 nm to 500 nm.", "If a tactile device for determining the surface topography is combined with a confocal optical microscope such as a confocal Raman microscope, one tactile device suitable for being combined with the Raman microscope is the atomic force microscope (AFM).", "In regard to AFM microscopy, reference is made to WO 02/48644 A1 that discloses such an AFM.", "With an AFM, the sample surface is scanned with the assistance of a scanning probe in the form of a tip.", "The content disclosed in WO 02/48644 is completed included in the present application.", "As described above, in confocal microscopy, the light from a monochromatic light source is guided on the path to the sample through a lens and is thereby substantially focused on a point of the sample surface.", "If the device is in particular a confocal Raman microscope, a spectrometer can break down the light spectrally that is emitted by the sample, i.e., the Raman or fluorescent light.", "Such a spectral breakdown can be done in a spectrometer, for example using a grating or a prism.", "If the light broken down in this manner is captured with a CCD camera, it is possible to capture the entire spectrum of the Raman or fluorescent light scattered by the sample.", "The advantage of spectrally breaking down the Raman light with a Raman microscope is that any spectral range can be selected to be measured by the detector for example by rotating the grid.", "The device, especially the confocal microscope, preferably the confocal Raman and/or confocal fluorescence microscope, can have a movable sample table that makes it possible to image the sample surface for example by moving the sample.", "Alternately or in addition, the excitation light source for the detector can be moved to obtain an image of the sample.", "It is also possible to record spatial maps of spectral properties of the sample.", "A very high depth resolution is achieved, in particular with a confocal image.", "The movability of the sample table makes it possible to scan the sample or sample region.", "As described above, the confocal chromatic sensor is generally also arranged in addition to the imaging device, i.e., with its own beam path.", "The surface topography determined for example with the assistance of a confocal optical sensor is generally used in downstream or simultaneous Raman measurement to keep the sample surface continuously within the focal plane of the lens while sampling, e.g., within the plane for confocal Raman microscopy.", "The X-Y scan of the sample is expanded into an X-Y-Z scan, the Z scan serving to compensate for the sample topography.", "The method and device as described before according to the first aspect of the invention enables a surface topography of a sample to be determined for confocal microscopy and the surface to be imaged to be brought into a confocal plane with the aid of the surface topography values.", "For this purpose, the device as described before has a surface topography sensor.", "The surface topography sensor can be a confocal sensor having an optical system, preferably having reflective and/or diffractive components.", "Alternatively, tactile sensors such as a profilometer, AFM, a white light interferometer, a triangulation sensor, or a laser scanning system are specified.", "The system described according to the first aspect of the invention has the disadvantage that first the surface topography of the entire sample is evaluated and a fluorescence or Raman measurement in consideration of the evaluated surface topography follows the determinations of the surface topography.", "Alternatively thereto, the embodiments according to the first aspect of the invention describe performing a distance measurement with the aid of a surface topography sensor, in particular a chromatic sensor, determining a distance signal which is characteristic for the surface topography therefrom, and tracking the focal plane or confocal plane of the confocal microscope, in particular the confocal Raman microscope.", "This means that the sample is moved to bring it into focus.", "As long as the sample is not in focus, no Raman or fluorescence signal is detected.", "In the measurement of the surface topography using the chromatic optical sensor, light is solely sent to the surface, reflected there, and spectrally analyzed after reflection.", "The regulation or control in the embodiments as described before is always a tracking of the focus for the Raman or fluorescence light, when the surface topography was evaluated from the radiation reflected back into the chromatic sensor.", "This means that the sample can be located for a relatively long time outside the focus for the Raman or fluorescence signal, so that for a long time, no Raman or fluorescence signal is detected, which has the result that the Raman or fluorescence signal is weak.", "A further object of the invention is therefore to specify a method and a device, with which it is possible that a surface of a sample can be imaged in a confocal manner, i.e., with the aid of confocal microscopy faster than according to the first aspect of the invention.", "This presumes that the sample is always held in focus during the entire measurement, even with insufficiently flat sample topography, for example, a curved sample.", "This second object is achieved according to the invention in that a method is provided for imaging a plane or a surface, in particular a surface having a topography, with the aid of confocal microscopy, in particular confocal Raman and/or fluorescence microscopy,

radiation in a wavelength range which does not coincide with the wavelength range of the first light source and/or the Raman or fluorescent light.", "Furthermore, the focal plane of the second light source is moved by means of a separately controllable focal position into/onto the surface of the sample and the topography of the sample which is thus ascertained or evaluated from the control signal of the controllable focal position is used to readjust the focal plane of the first light source.", "The method according to the second object of the invention operates using two foci.", "The first

brought by means of a separately controllable focal position onto the surface of the sample.", "The separately controllable focal position can be set, for example, by an electrically focusable lens.", "A periodic excitation of the lens, by which the focus thereof is periodically modified, is particularly preferred.", "Whenever the focus of the second light source comes to rest on the plane of the surface of the sample, a signal is detected.", "This is to be attributed to the fact that as a result of the confocal principle, light of sufficient intensity is reflected back to the detector only when the focus of the second light source comes to rest on the sample, so that a signal can be detected.", "The topography of the sample ascertained or evaluated from the control signal of the controllable focal position is used to bring the sample into the focal plane of the confocal Raman and/or fluorescence microscopy.", "Using the method according to the second aspect of the invention, it is possible, by way of the continuous analysis of the focal plane of the second light source, to keep the sample permanently in the confocal plane of the Raman and/or fluorescence measurement

and method described in the first aspect of the invention, which merely represents tracking.", "Using the method according to the second aspect of the invention, it is possible to compensate for a technical and/or mechanical drift, so that longer measuring times are possible in relation to the method according to the first aspect of the invention, because thermal and/or mechanical drift is regulated out.", "The Raman and/or fluorescence measurement of liquids which vaporize, for example, is also possible, because the regulation according to the invention provides continuous tracking of the surface.", "According to the second aspect of the invention, the specified readjustment is used to keep the sample in the focal plane for the Raman and/or fluorescence measurement.", "The imaging of the plane surface, using confocal microscopy, in particular Raman and/or fluorescence microscopy, is achieved by scanning a plurality of regions of the plane surface, using an apparatus for

μm.", "Most preferable is a resolution in the x/y plane at least of 0.61 λ/NA, wherein λ is the wavelength of the Raman or fluorescence light and NA is the numerical aperture of the objective.",

for example, with the aid of an electrically focusable lens, wherein the lens is preferably excited periodically, for example, at a frequency of 0.1 Hz to 1 MHz, especially 0.1 Hz to 1 kHz, preferably 200 Hz to 800 Hz.", "In addition to the lenses, the focus of which is electrically changed, it is also possible to periodically move the lens mechanically.", "An alternative frequency range to the indicated range of 0.1 Hz to 1 MHz, especially preferably 200 Hz to 800 Hz is a frequency range of 0.8 kHz to 1 MHz.", "The sample is moved to the focal plane of the first light source, which is ascertained or evaluated with the aid of the second light source and, for example, the lens which can be electrically focused, independent of the confocal plane of the confocal Raman or fluorescence microscopy.", "The movement of the confocal plane of the Raman/fluorescence microscopy takes place practically simultaneously with the measurement of the focal position of the second light source by using a closed loop feedback controller.", "With the aid of the second light source, in particular the second laser light source, and the moving of the focus of the second light source with the aid of the electrically focusable lens, it is possible, for example, to keep the Raman microscope continuously on the surface of the sample or at a defined distance below or above it and therefore to operate confocal Raman microscopy even on a pronounced, i.e., nonplanar sample topography.", "The travel of the focal position of the second light source is performed, for example, with the aid of an electrically focusable lens by applying a periodic changing electrical voltage.", "Alternatively to an electronically focusable lens, it would also be possible to vary the focus position of the lens by displacing the lens.", "For the ascertainment of the focal plane by variation of the focus of the second light source, it is necessary to adapt the modulation depth of the focus to the roughness or topography of the sample.", "In one particularly preferred embodiment according to the second aspect of the invention, the readjustment of the focal plane of the first light source is performed by changing the distance between microscope objective lens and sample.", "This affects the offset of the modulated focus of the second light source and keeps this modulation near the surface.", "In a further embodiment according to the second aspect of the invention, it can be provided that the light of the first and second light sources is guided through the microscope objective lens.", "A

laser, is imaged on a point of the sample.", "Then this pixel is preferably focused preferably using the same lens on a pinhole in front of a detector.", "The size of the pinhole needs to be adapted to the image of the light pattern limited by diffraction.", "The image is generated by scanning a point from the illumination source over the sample; the sample is accordingly scanned point for point.", "The image contrast is significantly increased with this type of imaging since only the focal plane of the lens contributes to the imaging.", "In addition, the resolution can be reduced with the aperture of the pinhole to approximately λ/3 by approximately a factor of √2 due to the convolution of the refraction point.", "In addition, a three-dimensional image of the sample structure can be obtained with an axial resolution of approximately one wavelength.", "In regard to confocal microscopy, reference is for example made to DE 199 02 234 A1.FIG.", "1a shows a possible design of a

light 22 is coupled into a light conducting fiber 30 and reaches a spectrometer 40.In the spectrometer 40, the beam of Raman light is further expanded with a suitable lens to produce the beam 42 that

surface of the sample 16 can be determined from this signal, and hence the surface topography can be determined.", "The fact is exploited that the wavelength of the focal plane in which the sample surface is located manifests a maximum intensity in a spectrometer.", "By determining the intensities, each wavelength in the spectrometer 8140 can be assigned a sample distance, that is, the distance from the sample 16 to the refractive optical element 8122.With the assistance of the confocal chromatics sensor 80, it is hence possible to determine the topography of the sample perpendicular to the sample plane, that is, in the z direction, quickly and directly in a purely optical manner, that is, without time-consuming scanning.", "The confocal chromatic sensor 80 therefore enables the sample surface topography to be optically determined.", "Although the chromatic sensor has its own beam path in the present exemplary embodiment in FIG.", "1, this is not essential.", "In an alternative

chromatic optical sensor can lie within a wavelength range of 400 nm to 500 nm, and the light wavelength for exciting the Raman effect can be 532 nm.", "Such an arrangement would allow Raman spectra generally above 532 nm to be detected.", "Of course, it would also be conceivable to choose other wavelengths.", "As an alternative to two different wavelength ranges, the measurements can also alternate sequentially over time and be evaluated in a time-division multiplex device.", "The design shown in FIG.", "1b enables the topography of a sample surface to be tracked with the assistance of

via the same optical unit 10021 as the excitation light source for Raman and/or fluorescence measurements of the first laser light source on the sample and is guided via a dichroitic mirror 10082 to a beam splitter, which allows light from the second light source to pass in the direction of the mirror 10082 and optical unit 10021 and couples out the light of the surface reflected back through the optical unit 10021, so that the light reflected back from the sample surface is guided to a photodiode 10086.The reflected signal is detected therein and supplied to an analysis unit (not shown).",

prosthesis 100 in accordance with an embodiment hereof to perform a heart valve replacement procedure, more particularly a mitral valve replacement, with minimal blood flow stoppage or interruption.", "With reference to FIG.", "7, illustrating a cross-sectional view of a heart H, the heart H includes a left atrium LA, a left ventricle LV, a mitral valve MV and an aortic valve AV.", "Blood flow BF is depicted with directional arrows in FIG.", "7 in the left atrium LA, into left ventricle LV through mitral valve MV, and into the aorta through aortic valve AV.", "Mitral valve MV is saddle-shaped and includes two native leaflets, posterior leaflet PL and anterior leaflet AL, and chordae tendineae CT extend within the left ventricle LV between the native leaflets of the mitral valve MV and the papillary muscles.", "More particularly, chordae tendineae CT are cord-like tendons that connect the medial papillary muscle MPM to the posterior leaflet PL of the mitral valve MV and connect the lateral papillary muscle LPM to the anterior leaflet AL of the mitral valve MV.", "When the native mitral valve is operating properly, the native leaflets will generally function in such a way that blood flows toward the left ventricle LV when the leaflets are in an open position, and so that blood is prevented from moving toward the left atrium LA when the leaflets are in a closed position.", "During systole, when the native leaflets close to prevent backflow of blood into the atrium, the chordae tendineae CT assist in preventing the native leaflets from everting or prolapsing into the atrium by becoming tense and holding the native leaflets in the closed position.", "In accordance with an embodiment hereof, a valve prosthesis 100 can be positioned in the area of a malfunctioning mitral valve MV in accordance with the invention, thereby replacing the mitral valve.", "Advantageously, the method of use described herein utilizes side access into the heart H and the deployed, expanded configuration of anchors 110A, 110B of valve prosthesis 100 to move or push the native leaflets of the mitral valve MV out of the mitral valve space so that they do not interfere with operation of the valve prosthesis.", "In addition, side access into the left atrium LA of the heart H and the substantially planar deployed, expanded configuration of valve receiving portion 106 of valve prosthesis 100 avoids or minimizes interference with the chordae tendineae CT present in the left ventricle LV of the heart H. FIGS.", "6 and 7 illustrate an access zone or area AA for a left thoracotomy approach for a transcatheter or minimally invasive mitral valve replacement procedure.", "The left-sided approach offers some unique advantages, including a relatively shorter distance to the mitral valve over a right-sided approach as well as access within the mitral valve that allows the native valve leaflets to be moved or repositioned as will be described in more detail herein.", "Initially, a relatively short incision, approximately 5-8 cm in length, may be made in the fourth, fifth, or sixth intercostal space.", "In an embodiment hereof, deflation of the left lung may be performed prior to and/or concurrent with introduction of delivery catheter 440, and the deflated left lung may be repositioned to expose the heart.", "An incision or opening may be formed in the pericardium, anteriorly or posteriorly to the phrenic nerve depending on the individual anatomy, and another incision or opening may be formed in a wall of the left atrium LA, slightly superior to an annulus of the native mitral valve MV, to provide exposure of the native mitral valve MV.", "Delivery catheter 440 having valve prosthesis 100 in a delivery configuration therein (not shown in FIG.", "7) is advanced to the heart and through the incision of the left atrium LA until at least a distal portion of the delivery catheter, i.e., the distal portion containing valve prosthesis 100 contained therein, is disposed within or adjacent to the native mitral valve MV.", "In an embodiment, delivery catheter 440 so positioned may have been tracked through a trocar or other introducer device (not shown) that has been inserted through purse-string sutures (not shown) previously placed in the left atrium LA.", "The purse-string sutures would be tightened around the trocar or other introducer device and a hemostasis valve would also be used to minimize blood leakage from the heart during the percutaneous replacement-valve implantation procedure, as would be understood by one of ordinary skill in the art.", "As previously noted, the proximal ends (not shown) of delivery catheter 440 and its components extend out of the body to be accessible by a clinician.", "Once the distal portion of delivery catheter 440 is positioned proximate to the native mitral valve MV as desired, first or distal anchor 110A of valve prosthesis 100 is released by retracting outer sheath 442 of delivery system 440 by a sufficient amount that this portion of the prosthesis is exposed as shown in FIG.", "8.Due to the self-expanding properties thereof, distal anchor 110A and a portion of valve receiving portion 106 adjacent thereto will expand radially outwardly relative to the sheath in which it was enclosed and return to the expanded, deployed configuration in which distal anchor 110A is oriented substantially perpendicular to valve receiving portion 106.During deployment of distal anchor 110A, second or proximal anchor 110B and the remainder of valve receiving portion 106 remain in the compressed configuration within outer sheath 442 of delivery catheter 440.Distal anchor 110A of valve prosthesis 100 is then secured to a wall of the heart as shown in FIG.", "9.More particularly, valve prosthesis 100 is distally advanced through distal advancement of inner tube 444 (not visible in the view of FIG.", "9) until distal anchor 110A contacts or abuts against the wall of the heart.", "The anterior leaflet AL of the native mitral valve MV is pinned or captured between the wall of the heart and distal anchor 110A.", "When pressed against the wall of the heart, distal anchor 110A conforms to the wall of the heart and barbs 130 (visible in FIG.", "8 but not visible in the view of FIG.", "9) are pressed into the wall of the heart to assist in securing the prosthesis to the native anatomy.", "Alternatively, distal anchor 110A may contact the wall of the heart and be secured thereto upon release from delivery catheter 440 and self-expansion thereof without requiring additional positioning thereof.", "Continued proximal retraction of outer sheath 442 releases the remainder of valve prosthesis 100, including second or proximal anchor 110B, from delivery catheter 440.Due to the self-expanding properties thereof, proximal anchor 110B and the remainder of valve receiving portion 106 expands radially outwardly relative to the sheath in which it was enclosed and return to the expanded, deployed configuration in which the proximal anchor is oriented substantially perpendicular to valve receiving portion 106 as shown in FIG.", "10 (delivery catheter 440 is omitted from the view of FIG.", "10 for sake of clarity).", "Upon release from delivery catheter 440, proximal anchor 110B contacts the wall of the heart and is secured thereto, thereby pinning or capturing the posterior leaflet PL of the native mitral valve MV between the wall of the heart and proximal anchor 110B.", "When pressed against the wall of the heart, proximal anchor 110B conforms to the wall of the heart and barbs 130 are pressed into the wall of the heart to assist in securing the prosthesis to the native anatomy.", "All frame components, i.e., valve receiving portion 106 and anchors 110A, 110B, deploy or expand within the heart to be in apposition with the native mitral valve and functions as a replacement mitral valve.", "More particularly, the frame components exert an apposition force that acts against the annulus of the native mitral valve and/or any heart structure in which they come in contact to seal against paravalvular leakage.", "After implantation of valve prosthesis 100, delivery catheter 440 is removed from the heart with the purse-string sutures noted above being tightened

"The passages 13A and 15A may have a circular cross-section of substantially the same size (i.e.", "substantially the same diameter) as that of the pin 45.When assembling the connecting member 3, the pin 45 may be held by friction, welding, swaging, crimping, pressing, clamping or any other appropriate fixing solution inside the openings 13A, 15A, or otherwise attached to the legs 13, 15 of the

respect to the second member 2J.", "In other instances, the first member 1J may include first and second lateral legs positioned on opposing sides of a central part of the second member 2J, for example, with a pin 45 hingedly coupling the first and second members 1J, 2J together, similar to that described above.", "In other embodiments, the pin 45 may be a unitary portion of one of the first and second members 1J, 2J.", "The fixing device 1 further comprises a flexible member 20 (shown in FIG.", "2, not depicted in FIG.", "1) passing through the main body 2, e.g.", "through the first member 1J, through the first passage 5 between the members 1J, 2J, and through the second member 21 The flexible member 20 extends from the main body 2 to form a loop 20P around a bony structure (not shown).", "Here, the flexible member 20 has two end portions 20E and an intermediate portion forming said loop 20P.", "The flexible member 20 may be configured such that the loop 20P extends outside the main body 2 from a passage or opening 21 provided in the first member 1J, and the end portions 20E extend from the main body 2 from a passage or opening 22 provided in the second member 2J see FIGS.", "1-2.The loop 20P may be tightened or tensioned around a bony structure by pulling on the end portions 20E, and the flexible member 20 may be locked in position by clamping the portions 1J, 2J and thus pressing the flexible member 20 between the support member 4 and a surface of the first and/or second member 1J, 2J.", "In this example, there is only one exit opening 22 for the end portions 20E and one loop opening 21 for the loop 20P.", "However, in other examples, not shown, the main body 2 may be provided with two exit openings, i.e.", "one for each end 20E of the flexible member

locked in position relative to the main body 2, by distinct locking systems.", "The main body 2 may be provided with a first passage 5 for receiving a portion of the support member 4.The first passage 5 may be defined by recesses provided in the inside faces of the first and second members 1J, 2J.", "The exit opening 22 and the loop opening 21 both communicate with the first passage 5.In the appended figures, the exit opening 22 is located above the first passage 5 whereas the loop opening 21 is located below the first passage 5.When the flexible member 20 is passed through the main body 2 and the support member 4 may be placed into the main body 2, between the members 1J, 2J, portions of the flexible member 20 (located between the end portions 20E and the loop 20P) may be held between the support member 4 and the inside faces of the members 1J, 2J defining the first passage 5.In the illustrated example, the exit opening 22, the first passage 5, and the loop opening 21 are substantially aligned and the flexible member 20 passes on the same side of the support member 4.In other examples, not shown, portions of the flexible member 20 may pass on each side of the support member 4, i.e.", "one branch of the flexible member 20 may pass on one side of the support member 4, while the other branch of the flexible member 20 may pass on the other side of the support member 4.In other embodiments, the main body 2 may be a single member having a passage 5 extending therethrough for receiving the support member 4 therein.", "The openings 21, 22 for the flexible member 20 may communicate with the passage 5, such that the support member 4 may contact or press against portions of the flexible member 20 passing through the main body 2.The fixing device 1 may also include a clamping mechanism to secure the support member 4 and/or the flexible member 20 to the main body 2.The support member 4 and the flexible member 20 may be simultaneously or separately secured to the main body 2.In some instances, a first clamping mechanism, e.g.", "a threaded fastener, may be used to clamp the support member 4 to the main body 2 and a second clamping mechanism, e.g.", "a threaded fastener, may be used to clamp the flexible member 20 to the main body 2, or a single clamping mechanism, e.g.", "a threaded fastener, may be used to simultaneously clamp the support member 4 and flexible member 20 to the main body 2.In the illustrative embodiment, the fixing device 1 comprises a clamping mechanism for bringing and maintaining the first and second members 1J, 2J in a clamping position in which the support member 4 and the flexible member 20 are held tight.", "Here, the support member 4 and the flexible member 20 are simultaneously clamped to the main body 2.In the illustrated example, the clamping mechanism comprises a screw 6.The screw 6 has a shank 6B going through the first and second members 1J, 2J, and a head 6A having a profile (being internal or external) that allows the screw 6 to be driven in rotation.", "In more detail, the screw shank 6B may pass through an orifice 9 provided in an engagement portion 12J of the second member 2J, and can be screwed into a threaded hole 33 formed in an engagement portion 10 of the first member 1J.", "The screw shank 6B may be provided with an external thread for engagement with the internal thread of the hole 33.The screw 6 and the engagement portions 11J, 12J of the first and second members 1J, 2J may be located on the side of the main body 2 which is opposite to the hinge (i.e.", "to the hinge axis A), with respect to the support member 4.By tightening the screw 6, the first and second members 1J, 2J may be moved toward each other and the support member 4 may be clamped inside the first passage 5, between the first and second members 1J, 2J, while the flexible member 20 may be simultaneously clamped between the support member 4 and members 1J, 2J.", "The screw head 6A may have a generally spherical, convex or conical shape and the lower part of the screw head (i.e.", "the part close to the shank 6B) may define a first sloped or curved surface.", "When the screw 6 is tightened, the screw head 6A may come into abutment with a second sloped or curved surface defined on the outside face of the engagement portion 12J, around the orifice 9, and the screw head 6A may push on the engagement portion 12J.", "In the example of FIG.", "3, the fixing device 1 further comprises a bone anchor 100.Here, the bone anchor is a bone screw 101 and, more particularly, a pedicle screw.", "The screw 101 comprises a threaded shank 106 as an example of a bone anchoring part, and an upwardly extending upper portion, or connection head 108, being integral with the shank 106.The connection head 108 comprises a receiver 110 and a compression member 118.The receiver 110 is generally U-shaped and defines a pair of opposed upstanding arms 162 integral with a base part 160 and forming a cradle and defining a slot or channel 164 between the arms 162, the channel 164 opening outwardly through the upper and lateral sides of the receiver 110.The channel 164 may have a width for snugly receiving the rod 50 of the connecting member 3 between the arms 162.Each of the arms 162 may have an interior surface that defines an internal passage and is provided with an internal thread configured to mate under rotation with an external thread provided on the compression member 118, so that the compression member 118 can be inserted and advanced downwardly into the channel 164, between the arms 162.The rod 50 may be laterally or downwardly loaded into the channel 164.A tool engagement structure or inner drive 119 may be provided in the top surface of the compression member 118.The illustrated inner drive 119 is a multi-lobular cavity for engaging a driving tool (not shown) for screwing the compression member 118 into the receiver.", "When the compression member 118 is tightened, the compression member 118 pushes the rod 50 against the receiver 110, so as to fix the rod 50 relative to the whole screw 101.When using such a fixing device 1, the flexible member 20 and the screw 101 may both be attached to a bony structure.", "The bony structure may be a vertebra.", "Then, typically, the screw 101 is anchored to the pedicle of the vertebra and the flexible member 20 is attached to the lamina.", "Thus, two different points of anchorage are provided, which improves the pulling resistance of the fixing device 1.This is particularly interesting when the pedicle is small and/or deteriorated, e.g.", "due to osteoporosis, and does not provide sufficient purchase to hold the pedicle screw 101 through time.", "FIG.", "4 shows another example of fixing device 1.It differs from the example of FIG.", "3 only by the fact that a sleeve 170 is detachably coupled to the receiver 110 of the screw 101.Such a screw is sometimes called a “long flange screw”.", "In more detail, the sleeve 170 comprises two members or extensions 172 detachably coupled to and extending the receiver arms 162, respectively.", "Extensions 172 are provided with internal threads that match the internal threads of the arms 162 to form a continuous set of threads.", "Like the arms 162, extensions 172 are spaced from each other and define between them a gap in which the rod 50 can be inserted.", "When screwing the compression member 118 within the extensions 172, the compression member 118 pushes the rod 50 down to the base of the receiver 110.Such a configuration is particularly useful in a surgical spinal stabilization procedure called “reduction”.", "During reduction, the support member 4 and the vertebra (not shown) are caused to move toward each other.", "The screw 101 may be anchored into the pedicle of a vertebra, and the flexible member 20 may be attached to the lamina of the vertebra.", "This makes the vertebra easier to handle and move relative to the support member 4 and, thus, improves the control and accuracy of the reduction.", "FIG.", "5 shows another example of fixing device 1.It differs from the example of FIG.", "3 only by the fact that the threaded shank 106 of the bone anchor 100 is replaced by a hook 146.Here, the hook 146 has a distal hooking portion 147 configured for being hooked on the bony structure, a connection head 108 for receiving the rod 50 and an intermediate portion 148 between the head 108 and the hooking portion 147.The intermediate portion 148, which is optional, allows the hooking portion 147 to be offset relative to the rod 50 by a distance D2.This may render the positioning of the device easier.", "In particular, while the flexible member 20 is attached to the lamina of a vertebra, the hooking portion 147 may be anchored to the transverse process (instead of the pedicle) of the vertebra, which can be advantageous in certain situations and, in particular, may provide additional therapeutic options to the surgeon in certain situations.", "With reference to FIGS.", "3-5, it is to be noted that the rod 50 is offset relative to the first passage 5 of the connecting member 3 and, thus, relative to the support member 4, while the flexible member 20 is substantially in alignment with the first passage 5.This offset design is well adapted to certain situations and, in particular, when the support member 4 is to be implanted substantially along the lamina median plan of a spine.", "In such a case, the flexible member 20 may be attached to the lamina of a vertebra, while the bone anchor 100 may be attached to the pedicle or transverse process of the vertebra.", "Since, for anatomical reasons, the pedicle and transverse process of a vertebra are distant from the lamina of the vertebra, the offset design between the rod 50 and the support member 4 is advantageous.", "It is also to be noted that the stable and strong fixation provided by the fixing device 1 is particularly advantageous when used for fixing an end of the support member 4 to a bony structure, as illustrated in FIGS.", "3-5.Besides, the fixing device 1 being autostable, it allows the surgeon (or other operative) to independently fix the end of the support member 4 to the bony structure, if needed.", "FIG.", "6 shows an example of a stabilization system for stabilizing vertebrae (not shown), the system comprising: a first fixing device 1 configured to be fastened to a first vertebra, a second fixing device 1′ configured to be fastened to a second vertebra, a third fixing device 1″ configured to be fastened to a third vertebra, and a support member 4—e.g.", "a rod—for connecting the fixing devices together, thereby providing stabilization between the vertebrae.", "In this example, the fixing devices 1, 1′, 1″ are similar to that of FIG.", "3.Each fixing device 1 may be fixed to a vertebra at two anchor points by means of its flexible member 20, 20′, 20″ and its bone anchor 100, 100′, 100″ (here a pedicle screw) respectively.", "As a result, the pulling resistance of the whole system is increased.", "It is to be noted that, in particular situations, the fixing device of FIG.", "6 may be used to strengthen the fixation of already existing, or “old”, bone anchors 100, 100′, 100″ primarily fixed to a bony structure.", "In such situations, the old support member 4 primarily connected to the bone anchor may be removed therefrom and the rods 50, 50′, 50″ of the fixing device 1, 1′, 1″ may be connected to the old bone anchor 100, 100′, 100″, in place of the old support member 4.The old support member 4, or a new one, may then be clamped within the connecting members 3, 3′, 3″ of the fixing devices which are each attached to the bony structure via their flexible members 20, 20′, 20″.", "The flexible members 20, 20′, 20″ provide secondary anchor points to the bony structure, in addition to the primary anchor points provided by the old bone anchors 100, 100′, 100″.", "Thus, the pulling resistance of the whole system is increased.", "FIG.", "7 shows another example of a stabilization system for stabilizing vertebrae (not shown), the system comprising: a first bone anchor 100 configured to be fastened to a first vertebra, a second bone anchor 100′ configured to be fastened to a second vertebra, and a support member—e.g.", "a rod 4—for connecting the bone anchors 100, 100′ together, thereby providing stabilization between the vertebrae.", "Here, the bone anchors 100, 100′ are pedicle screws such as the one shown in FIG.", "3 but those screws are used alone, their connection head receiving the support member 4.In this example, fixing devices 1 and such as the one of FIGS.", "1-2, comprising connecting members 3, 3′, flexible members 20, 20′, but no bone anchor, may be used to increase the stiffness of the support member 4, along a certain length thereof.", "To do so, the fixing devices 1 and 1′ may be linked together by means of a connection sleeve 130.The connection sleeve 130 may define at least one internal through passage adapted for receiving the rods 50, 50′ of the devices 1, 1′.", "In other instances, the connection sleeve 130 may define blind openings, recesses, or other passages for receiving the rods 50, 50′.", "The rods 50, 50′ may be locked within the sleeve 130 by screws 132 protruding inside the internal passage when they are screwed down into the sleeve 130.Thus, the rods 50, 50′ may be connected end-to-end via the connection sleeve 130.In other instances, the ends of the rods 50, 50′ may be offset within the connection sleeve 130.Each of the fixing devices 1 and 1′ may also be connected to a vertebra via its flexible member 20, 20′, and to the support member 4 via its connecting members 3, 3′.", "As a result, at least the support-member portion 4A located between the fixing devices 1 and 1′ may be stiffened due to the rods 50, 50′ and to the anchor points provided by the flexible members 20, 20′.", "FIGS.", "8 and 9 show another example of a stabilization system for stabilizing a bony structure.", "Such a system is particularly intended for stabilization of the C1-C2 segment of a spine, i.e.", "the spinal segment including the atlas (the cervical vertebra C1) and the axis (the cervical vertebra C2).", "The cervical vertebrae are the smallest vertebrae in the spine, reflective of the fact that they support the least load, and vertebra C1 is quite different from the other spinal vertebrae.", "Most notably it has no body or spinous process, but instead consists of a ring of bone made up of two lateral masses joined at the front and back by the anterior arch and the posterior arch.", "For these reasons, most of the stabilization systems are not well adapted to C1-C2 stabilization.", "The system of FIGS.", "8-9 comprises a first fixing device 1, a second fixing device 1′ and a support member 40 for connecting the fixing devices 1, 1′ together.", "In this example, the fixing devices 1, 1′ are similar to the one of FIG.", "3.Each fixing device 1, 1′ comprises a connecting member 3, 3′ with a rod 50, 50′, a flexible member 20, 20′ and a bone anchor 100, 100′.", "Here, the bone anchors 100, 100′ are pedicle screws 101, 101′.", "The support member 40 may be U-shaped and define two branches 41, 42 joined together by a base 43.The two branches 41, 42 may be fixed to the first and second connecting members 3, 3′, respectively, in the same way as the support member 4 is fixed to the connecting member 3 in FIG.", "3.Such a stabilization system may be used as follows.", "The flexible members 20, 20′ are attached to the lateral masses of vertebra C1, respectively, while the bone anchors 100, 100′, are anchored to the pedicles of vertebra C2,

reported in 1997 and it was given the name SSZ-39.The previous materials with the AEI framework features were AlPO-18 (an aluminophosphate) and SAPO-18 (a silicoaluminophosphates).", "The AEI framework describes a material that has 8-membered ring (MR) openings and constitutes a 3D channel (8×8×8) system with equal pore sizes of 3.8×3.8 Å and medium size cages that can contain spheres up to 7.3 Å.", "Lately, there has been an increase of interest in 8MR systems for catalysis and gas separations.", "Two very promising catalytic applications are the methanol (or oxygenates) to olefins conversion (MTO) and the selective catalytic reduction (SCR) of NO x in flue and exhaust gases.", "Specific 8MR materials of interest for such applications have been found within the CHA, LEV, AFX, KFI, RTH and AEI topologies.", "More specifically, Cu-exchanged AEI type materials, such as Cu-SAPO-18 and Cu-SSZ-39, have been found to be very efficient and stable in the SCR reaction.", "SAPO materials and zeolites only provide exchange sites for divalent ions (such as Cu 2+ ) when framework heteroatom (Al in the zeolite case, Si in the SAPO case) substitution is high and these sites are close to each other.", "This can for instance occur in bridged substitution sites, as seen in FIG.", "1(A) for zeolites or when the sites are close enough due to the shape of the composite building unit of the framework, as seen in FIG.", "1(B) for a d6r zeolite building block.", "A molecular sieve with divalent species built in into a siliceous framework in a tetrahedral fashion ideally gives the framework a local charge deficit of −2.This local charge deficit can be balanced by cationic species such as H + , Na + , Li + , et cetera but also by divalent cations such as Cu 2+ , Ca 2+ , Ni 2+ , etc.", "as shown in FIG.", "1(C) for zincosilicates.", "The catalytic and gas separation properties of molecular sieves highly depend on the type of exchanged cations and the framework sites they balance.", "For the SCR of NO x with zeolites, it has been noted that only divalent cationic Cu 2+ , ideally exchanged near two negative framework charges, are key in the catalytic cycle.", "Over-exchanged samples, for instance when [Cu(OH)] + species are present near a negative framework charge, could be less appealing.", "In most aluminosilicate materials, the amount of divalent exchange sites are thus limited and require the use of zeolites with a low Si/Al ratio.", "The introduction of Zn along with Al in suited zeolites, creating zincoaluminosilicates, would therefore increase the number of (divalent) exchange sites.", "Moreover, active sites for sorption and catalysis derived from cations exchanged on framework Zn, or the framework Zn site itself, could react differently compared to classic Al-based active sites.", "However, the use of zincosilicate molecular sieves can often be limited due to their lower stability against hydrolysis or collapse, which is especially striking compared to the high stability of silicate or aluminosilicate molecular sieves.", "Therefore, and for other reasons of catalytic nature, it is desirable to create zincoaluminosilicate materials, rather than pure zincosilicates.", "Synthesizing such materials is difficult and only very few have ever been reported.", "A notable example is a VET analogue called SSZ-41 which can contain both Zn and Al in the framework.", "However, this material closely resembles the VPI-8 material, which is a pure zincosilicate, due to its very low aluminum content.", "Other documented zincoaluminosilicates are found in MAZ, OFF, and FAU topologies but there, the proof of Zn incorporation is not unambiguous.", "Materials incorporating both Zn and Al in appropriate amounts

provided a reliable way to assess the stability of materials.", "TGA can be a harsh thermal treatment that can destroy microporous materials due to the high temperatures reached (900° C.), as well as

controls, the PXRD visible crystallinity was totally preserved after TGA, indicative of the fact that the collapse of the Zn—Al-AEI material was not the collapse of a physical mixture of SSZ-39 induced by the presence of extra-framework Zn species.", "In other words, if the Zn—Al-AEI was either a physical mixture of SSZ-39 (“aluminosilicate Al-AEI”) and ZnO or a Zn-exchanged SSZ-39, the structural collapse could not be explained.", "The collapse in TGA was also observed for the calcined and ozone-treated Zn—Al-AEI materials (not shown).", "Example 2.3.Characterizations by Ion-Exchange Balance Once having prepared these materials, there was an expectation that the ion-exchange capacity (and especially for divalent cations such as Cu2+) would be higher for these zincoaluminosilicate matrices relative to the aluminosilicate analogs, especially given that both samples have a similar Al content (Si/Al ratio).", "A complication with zinc species in tetrahedral framework positions was the relative ease of their hydrolysis and subsequent leaching in even slightly acidic media.", "It was noted that traditional ion-exchange methods affected the Si/Zn ratios (e.g.", "when 1M NH4+-nitrate solutions were used, the Si/Zn ratio rose from 11.3 to 39.3 for calcined MDU143).", "Because of the increasing insolubility of Cu2+ species at pH>6.5, a Schweizer's reagent (tetraaminediaquacopper dihydroxide) was used as ion-exchange medium.", "This provided a slightly basic way (pH around 9) to introduce Cu2+ to the exchange sites and so protect the Zn sites from hydrolysis.", "By calcination, the ammonium ligands were then removed and the Si/Zn, Si/Al, and Cu/Al ratios were measured by EDS (Table 3) for an exchanged SSZ-39 and Zn—Al-AEI.", "A remarkable difference was found between SSZ-39 and Zn—Al-AEI: the latter could exchange 0.35 Cu/Al (mol/mol), while the former could only attain a 0.24 Cu/Al ratio.", "Even though some Zn seemed to be lost in the exchange (Si/Zn rose from 11 to 15), a 45% larger ion-exchange capacity was thus found for the new material, strongly indicative that at least a significant part of the Zn atoms are present in the tetrahedral (alumino)siliceous AEI framework.", "Moreover, the high Na/Al ratio of the washed, calcined MDU143 material (Table 3) supported this conclusion: a high 1.8 value was obtained, whereas for classic SSZ-39 samples (not measured for MDU182), Na/Al values below 0.5 are usually obtained.", "In this case, along with the OSDA cation, Na+ compensated part of the framework charge during

charges that are not balanced by OSDA are compensated by Na+ due to the high Na content of the gels.", "Example 2.4.Characterizations by 29Si-NMR The final and most direct proof for the present characterization was the observation of additional Zn-derived signals in the 29Si NMR spectra of the Zn—Al-AEI materials when compared to the Zn-free SSZ-39 (FIG.", "7).", "Both materials had a similar Si/Al ratio (viz.", "Table 1, 2).", "The ratio of the signal of Si—(Si)4— sites at −110 ppm and the Si—(Si)3—(Al) sites at −105 ppm of about 2:1 in SSZ-39 was in line with its Si/Al ratio of about 8 of and the presence of mainly isolated Al sites in the siliceous matrix.", "The calcined and ozone-treated Zn—Al-AEI materials displayed a much higher signal at −105 ppm.", "This was likely due to the superposition of both Si—(Si)3—(Zn) and Si—(Si)3—(Al) signals.", "The Si/Al ratio of this material (7.7) could not have caused the −105 ppm signal to be nearly as intense as the −110 ppm signal.", "Additionally, in these new materials, a signal at −98 ppm was found, that was likely related to the presence of silanols [Si—(Si)3—(OH)] in the material.", "This could for instance be enhanced by the presence of trifold tethered Zn in a siliceous environment, when one of the tetrahedral Zn—O—Si bond has been hydrolyzed or did not form completely.", "Considering the ease of hydrolysis demonstrated in the exchange experiments, this was likely.", "To further support the present conclusion that the additional signals in the Zn—Al-AEI derived from framework Zn, the ozone-treated Zn—Al AEI material was acid-treated, first in mild and then in harsh conditions (for conditions, see FIG.", "7).", "The mild treatment did not remove much of the Zn from the framework as evidenced by the Si/Zn ratio of 19 mentioned next to the NMR trace and the trace itself.", "After the harsh treatment, no Zn could be detected with EDS.", "And after calcination, the 29Si NMR spectra of the harsh treated one resembled that of the calcined aluminosilicate SSZ-39.The crucial overlays of this Zn-free Zn—Al-AEI with both the SSZ-39 and the Zn—Al-AEI are shown in FIG.", "8.The PXRD trace of this material was also identical to that of a calcined SSZ-39 (not shown) and its reflections were stable after TGA analysis (not shown), confirming the removal of Zn and the creation of a type of SSZ-39 from a Zn—Al-AEI by removing the framework Zn.", "This confirms the presence of framework zinc in the starting material.", "Example 2.4.Extension to Other Frameworks The synthesis and properties of a novel zincoaluminosilicate having AEI topology is crystalline and isostructural with AlPO-18 and SSZ-39, as it has a framework with the AEI topology (framework code of the structure commission of the International Zeolite Association).", "To further extend the methodology, the synthesis of zincoaluminosilicates with the GME and CHA topologies are also shown.", "Entries 6 and 7 of Table 1 demonstrate the relative ease with which the synthesis of Zn—Al-CHA and Zn—Al-GME was possible using similar synthetic recipes with the right OSDA and adequate conditions.", "The corresponding PXRD traces of these materials can be found in FIG.", "9 and match well with databases.", "For GME, an aluminosilicate control is given, with a Si/Al ratio of 4.1.Some of the reflections of the Zn—Al-GME were clearly shifted towards lower 2θ values (viz.", "dashed lines).", "This indicated that there was a measurable enhancement in certain dimensions of the unit cell for the zincoaluminosilicate version of GME, a framework with 12MR 1-dimensional channels.", "This was expected given the larger nature of Zn atoms and the higher level of heteroatom (Al+Zn) substitution in the zincoaluminosilicate framework.", "Example 3.Final Comments The totality of the available data support the conclusion that at least part of the Zn atoms in the Zn—Al-AEI material are present as tetrahedral framework species in an aluminosilicate matrix.", "Based on the AEI, CHA and GME examples, it is also shown that this zincoaluminosilicate synthesis method can be extended to other framework types, especially for those topologies where aluminosilicate compositions with high Al content are easily formed and more specifically, for topologies that contain the d6r composite building block (see International Zeolite Association, Database of Zeolite Structures), seen in FIG.", "1(B)).", "These two criteria are common denominators for CHA, AEI and GME type materials.", "As those skilled in the art will appreciate, numerous modifications and variations of the present invention are possible in light of these teachings, and all such are contemplated hereby.", "For example, in addition to the embodiments described herein, the present invention contemplates and claims those inventions resulting from the combination of features of the invention cited herein and those of the

wireless communication system and, in particular, to an operation method and apparatus of a high version (Rel-10) terminal in case of existence of MBSFN subframe supporting unicast in the high version (Rel-10) network of Long Term Evolution (LTE) system in which terminals with different versions (Releases 8, 9, 10, etc.)", "coexist.", "Description of the Related Art With the rapid advance of the wireless communication technology, the communication systems have evolved to the 4th Generation mobile communication system represented by LTE system.", "In the LTE system, the data is transmitted in unit of frame having a length of 10 msec, a frame consisting of 10 subframes.", "FIG.", "1 is a diagram illustrating a structure of a downlink frame used in the LTE system.", "In FIG.", "1, the frame 101 consists of 10 subframes 103 including normal subframes 150 carrying normal data and Multimedia Broadcast multicast service Single Frequency Network (MBSFN) subframes 107.The normal and MBSFN subframes differ from each other in number of Orthogonal Frequency Division Multiplexing (OFDM) symbols, length of Cyclic Prefix (CP), and structure and number of Cell-specific Reference Signal (CRS), and the MBMS subframe is used only for the purpose of transmitting broadcast and multicast data in Rel-8 and Rel-9 systems.", "As the system evolves, however, the MBSFN subframe can be used for the purpose of unicast transmission to a specific terminal as well as broadcast/multicast in the LTE Rel-10 or later.", "For unicast data transmission/reception, the resource allocation information indicating the resource allocated for transmission/reception is carried on the Physical Downlink Control Channel (PDCCH) and the real data is carried on the Physical Downlink Shared Channel (PDSCH).", "The terminal determines whether there is any resource allocation information addressed thereto on the PDCCH before attempt receiving real data.", "In this case, the LTE Rel-10 terminal has to check the PDCCH carrying the resource allocation information for the MBSFN subframe in order to receive PDSCH through even the MBSFN subframe.", "However, if the LTE Rel-10 terminal has to check PDCCH in every MBSFN subframe, this may cause unnecessary operation depending on whether the MBSFN subframe carries terminal-specific unicast data or multicast/broadcast data.", "SUMMARY The present disclosure has been made in an effort to address this problem, and it is an object of the present disclosure to provide a method for a terminal to receive data in a situation where different type subframes exist in the wireless communication system including networks operating with different versions of LTE.", "In the case that the new version (Rel-10 or later) terminal is in a new version network, the terminal receives information on whether PDSCH reception over MBSFN subframe through broadcast or unicast is supportable from the new version network and, if supportable, takes operation for interpreting PDCCH for receiving PDSCH over MBSFN subframe and, otherwise if not supportable, skips corresponding operation in MBSFN subframe.", "In the disclosed method, the new version terminal operating in a new version network reduces unnecessary operation for data reception when unicast data transmission is not supported in the network, depending on whether the network supports unicast data transmission in MBSFN subframe, resulting in reduction of power consumption.", "In accordance with an aspect of the present invention, a method by a base station in a wireless communication

subject matter of the present invention.", "Exemplary embodiments of the present invention are described with reference to the accompanying drawings in detail.", "In the present disclosure, the description is directed to the LTE system for convenience purpose.", "There are several releases of LTE and among them the legacy Rel-8 and Rel-9 do not support PDSCH reception in MBSFN subframe.", "Accordingly, the legacy terminal does not attempt decoding PDCCH for receiving Downlink Control Information (DCI) including PDSCH scheduling information for receiving PDSCH in MBSFN subframe.", "In the Rel-10 or later system, however, it is allowed to transmit PDSCH in MBSFN subframe.", "In this case, unlike the legacy terminal which takes no action for MBSFN subframe because it cannot receive PDSCH in MBSFN subframe, the new terminal has to take an action for receiving PDSCH to acquire DCI including scheduling information for receiving PDSCH in MBSFN subframe.", "In the following description, new terminal denotes an LTE Rel-10 terminal, i.e.", "the terminal capable of receiving PDSCH in MBSFN subframes.", "FIG.", "2 is a flowchart illustrating the new terminal procedure in the method according to an embodiment of the present invention.", "The new version terminal receives a downlink frame structure in System Information Block broadcast by a base station at step 203.The downlink frame structure is transmitted in the form of a bitmap indicating positions of MBSFN subframes.", "Next, the terminal receives information on whether the base station supports PDSCH over MBSFN subframe at step 205.The PDSCH over MBSFN subframe supportability can be broadcasted in the system information of the base station or transmitted to the individual terminals through respective control messages.", "The PDSCH over MBSFN subframe supportability information can be transmitted in a Radio Resource Control (RRC) message explicitly with a newly defined indicator or implicitly with a legacy information (e.g.", "predefined channel configuration information, transmission mode information, etc.).", "Steps 203 and 250 can be performed in opposite order.", "In the case of legacy network or legacy base station, the supportability information on PDSCH over MBSFN is not transmitted.", "If no supportability information on PDSCH over MBSFN is received, the UE assumes that the base station does not support PDSCH of MBSFN.", "If it is determined at step 207 that PDSCH over MBSFN subframe is supported, the UE receives PDCCH including DCI, at step 209, for receiving PDSCH in MBSFN subframes based on the information received at step 205.If it is determined at step 207 that PDSCH over MBSFN subframe is not supported or if no supportability information on PDSCH over MBSFN subframe is received, the terminal takes no action for receiving PDSCH in MBSFN subframe.", "In this case, the terminal does not perform any operation for receiving PDSCH.", "FIG.", "3 is a block diagram illustrating the configuration of the terminal according to an embodiment of the present invention.", "The terminal communicates data with higher layer 305 and transmits/receives control messages through a control message processor 207.The terminal multiplexes the control signals or data by means of the multiplexer/demultiplexer 303 and transmits the multiplex result by means of the transceiver 301 under the control of the controller 309.The terminal demultiplexes the physical signal received by the transceiver 301, by means of the multiplexer/demultiplexer 303, and transfers the demultiplexed signals to the higher layer 305 or control message processor 307 under the control of the controller 309.In the present disclosure, the terminal receives MBSFN subframe configuration information broadcasted by the base station and receives the supportability information on PDSCH over MBSFN subframe through broadcast or unicast.", "Such a control message is received, the control message processor 307 transfers to the controller 309 the information on whether each subframe is normal or MBSFN subframe and whether PDSCH over MBSFN subframe is supported in order to determine whether to receive PDCCH for receiving PDSCH at every subframe.", "That is, if PDSCH over MBSFN subframe is supported, the terminal performs operation for receiving PDSCH even in MBSFN subframes and, otherwise PDSCH over MBSFN subframe is not supported, performs no action for receiving PDSCH in MBSFN subframes.", "Although the block diagram of the terminal is directed to the case where the function blocks are responsible for different functions, the present invention is not limited thereto.", "For example, the controller 309 may perform the functions of the control message processor 307.In the disclosed method, the network notifies the new version terminal whether it supports PDSCH over MBSFN subframe so as to avoid unnecessary reception operation for receiving PDSCH over MBSFN subframe, resulting in reduction of power consumption.", "Although exemplary embodiments of the present invention have been described in detail hereinabove with specific terminology, this is for the purpose of describing particular embodiments only and not intended to be limiting of the invention.", "While particular embodiments of the present invention have been illustrated and described, it

embodiment of an anchor device 10 for use in providing an anchor device on a floor.", "In the embodiment shown, the anchor device 10 is used for securing, for example, a ceiling light to a ceiling.", "The anchor device 10 is arranged on the floor above the room where the ceiling light is to be installed.", "The cable for the ceiling light extends downwardly from the anchor device 10 through the floor to the room below, so that the ceiling light is suspended from the ceiling of the room below.", "The anchor device 10 is particularly useful where the floor is to be a concrete floor.", "In such circumstances, the concrete floor is constructed by first providing a wood form 100 upon which the concrete is laid.", "When the concrete has set the wood form is removed.", "Prior to pouring the concrete, the anchor device 10 is arranged on the wood form 00 in positions where a ceiling light is to hang from the ceiling of the room below.", "Alternatively, the wood form may remain in place.", "An opening 102 (see FIGS.", "3, 4 and 5) can be drilled through the wood form 100 prior to mounting of the anchor device 10 thereon.", "The anchor device 10 comprises an article securing arrangement 12 and a receiving arrangement 14.The receiving arrangement 14 comprises first and second support portions 16, 18 extending opposite each other from the article securing arrangement 12.The article securing arrangement 12 comprises a body part in the form of a base element 20 and a dome shaped cover element 22.The base element 20 defines an aperture 21 therethrough.", "The cover element 22 extends over the base element 20 and defines a cavity 24 therewith.", "The cover element 22 provides a seal around the base element 20, thereby preventing the concrete from being received therein.", "An article can extend through the aperture 21 into the cavity 24.In the embodiment described herein, the article is an elongate suspension device 26, which may be used for suspending a ceiling light.", "The suspension device 26 includes a securing mechanism 27.The securing mechanism 27 is secured in the cavity 24 in a manner described below.", "Thus, an anchor assembly is provided, the anchor assembly comprising the anchor device 10 and the elongate suspension device 26.The base element 20 extends outwardly in opposite directions from the article securing arrangement 12 to provide the first and second support portions 16, 18.Thus, the base element 20 and the first and second support portions 16, 18 are formed of a single piece of a suitable material, for example a plastics material.", "The first and second support portions 16, 18 extend outwardly and upwardly from the base element 20.The receiving arrangement 14 further includes a plurality of fingers 28 on the first and second support portions 16, 18.The embodiment shown in FIGS.", "1 to 5 has eight fingers 28 arranged in two groups of four fingers 28 opposite each other.", "The fingers 18 extend from, and are supported by, the first and second support portions 16, 18.Gaps 30 are defined between adjacent fingers 28.A receiving space 32 is defined by each of the first and second support portions 16, 18 and the fingers 28.The receiving space can receive concrete spread on the lower layer 100, as explained in more detail below.", "Each finger 28 comprises a first region 28A extending outwardly from the first or second support portions 6, 18 and a second region 28B extending downwardly from the first regions 28A.", "Each of the second regions 28B has a V shaped distal end region 28C which can engage the lower layer 00.The anchor device 10 further includes holding means in the form of first and second tubular holding members 34, 36, through which fasteners in the form of nails 38 can extend into the lower layer 100.A floor engaging part 40 extends downwardly from the base part 20 and defines a channel 42 in communication with the aperture 21 in the base part 20.The channel 38 is aligned with the aperture 21, and tapers outwardly therefrom.", "The anchor device 10 is disposed on the lower layer 100 with the aperture 21 and the channel 42 in alignment with the opening 102.In this position, the distal end regions 28C of the fingers 28 engage the lower layer 100.In order to fasten the anchor device 10 to the lower layer 100, nails 38 are driven through the tubular holding members 34, 36 into the lower layer 100.Referring to FIGS.", "6A and 6B, the suspension device 26 comprises the securing mechanism 27 and an elongate cable 38.The securing mechanism 27 is provided on one end of the cable 38.The securing mechanism 27 comprises a main part 44 and a securing member in the form of a toggle 46 pivotally mounted on the main part 44.The toggle 46 can pivot between a non-securing position shown in FIGS.", "4 and 6, and a securing position shown in FIGS.", "5 and 6B.", "When the toggle 46 is in the securing position, the toggle 46 extends across the aperture 21, and cannot pass through the aperture 21.As a result, the toggle 46 is retained in the cavity 24, and the article is thus secured to the anchor device 10.As can be seen in FIG.", "4, the suspension device 26 is installed in the anchor device 10 by disposing the toggle 46 in the non-securing position, and pushing the securing mechanism 27 through the opening 102 in the floor and through the channel 42 and the aperture 21.This inserts the toggle 46 into the cavity 24.The toggle 46 is appropriately weighted so that, when it is inserted into the cavity 24, the toggle 46 pivots automatically to its securing position shown in FIG.", "5.This prevents the securing mechanism 27 from being removed from the anchor device 10, thereby securing the suspension device 26 to the anchor device 0.Alternatively, the toggle can be inserted into the cavity 24 so that, upon insertion, the toggle 46 engages the inside of the cover element 22, which dislodges the toggle 46 from its non-securing position to its securing position.", "When the anchor device 10 has been fastened to the lower layer 100 by the use of the nails 38, as described above, the concrete is spread over the lower layer 100, and over the anchor device 0 so that the anchor device 10 is wholly embedded within the concrete.", "During such spreading, the concrete flows through the gaps 30 between the fingers 28, and into the receiving spaces 32.When the concrete sets, the anchor device 10 is held in its position on the lower layer by the nails 38 and the concrete.", "There is thus described an anchor device 10 which allows suspension arrangements to be anchored thereon from which lights can be suspended.", "The anchor device 0 has an advantage that, in the embodiment described herein, the receiving portions extend outwardly from the main body over a distance which is substantially equal to the diameter of the main body.", "This allows the anchor device 10 to be of a low profile configuration, thereby making it less likely that workers pouring the concrete over the anchor device 10 will accidentally kick it thereby damaging it or themselves.", "A second embodiment of the invention is shown in FIGS.", "7 to 10.The second embodiment of the anchor device is generally designated 110, and is intended to be mounted in a well 202 of a metal deck 200 forming a floor (not shown).", "After the necessary number of the anchor devices 10 are mounted on the metal deck 200, concrete can be laid on the deck 200 to form the floor.", "Referring to FIGS.", "8, 9 and 10, the anchor device 110 comprises an article securing arrangement 2, which comprises a base element 120 and a cover element 122.The base element 120 defines an aperture 121.The cover element 122 is mounted on the base element 120 and defines a cavity 24 therewith, the aperture 121 providing communication between a region external of the anchor device 110 and the cavity 124.The cover element 122 provides a seal around the base element 120, thereby preventing the concrete from being received therein.", "The cover element 122 has a dome shaped body portion 126, which defines the cavity 124 with the base element 120.The cover element 122 may also have a substantially circular flange portion 128 extending outwardly from the body portion 126 to engage the base element 120.A circumferential edge member 129 extends downwardly from the flange portion 128 at the outer edge thereof.", "The edge member 129 defines a circular shallow recess 129A in which the base element 120 is received.", "The base element 120 is of a size that it just fits within the recess 129A.", "The base element 120 is in the form of a substantially circular disc.", "The aperture 121 is defined substantially centrally of the base element 120.The base element also defines a plurality of through holes 30 (see FIG.", "10) arranged in a circumferential array adjacent the outer edge of the base element 120.The flange portion 128 of the cover element 122 has a plurality of downwardly extending push-fit members 32.The push-fit members 132 and the through holes 130 are provided on or in the respective flange portion 28 and base element 120 in corresponding positions.", "The positions of the through holes 130 and the push-fit members 132 are such that the push-fit members 32 are received in the through holes 130 when the base portion 120 is received in the recess 29A.", "The push-fit members 132 are a tight fit within the through holes 30 and thereby secure the base element 120 to the cover element 122.The anchor device 110 is mounted on the metal deck 200 over an opening 204 therein, and is positioned on the metal deck 200 so that the aperture 121 in the base element 20 is aligned with the opening 204, as shown in FIG.", "10.A fastening means 134 is provided to fasten the anchor 10 to the deck 200.The fastening means 134 comprises a floor engaging member 136 to engage the deck 200.The floor engaging member defines a central aperture 135.The fastening means 134 further includes an elongate tubular fastening member 138 extending downwardly from the floor engaging member 136 at the aperture 35.The fastening member 138 defines a cylindrical passage 139 communicating with the aperture 135 in the floor engaging member 136.The fastening member 38 has a fastening formation in the form of a detent 140 closely spaced from the floor engaging member 136.The detent 140 is circular and extends around the tubular fastening member 138.A circular recess 142 is defined around the fastening member 138 between the detent 140 and the floor engaging member 136.In order to mount the fastening member on the deck 200, the tubular fastening member 138 is first inserted into the opening 121 from above, with the floor engaging member 136 uppermost.", "The fastening means 134 is then pushed downwardly through the opening 121 until the detent 140 engages the deck 200 around the opening 121.Further pushing of the fastening means 134 downwardly causes the detent 140 to deform inwardly until the detent passes over the deck 200.The detent 140 snaps back to its non-deformed position to engage the underside of the deck 200 around the opening 121.As a result, the region of the deck 200 surrounding the opening 121 is held between the detent 140 and the floor engaging member 136, thereby fastening the fastening means to the deck 200.The article securing arrangement 112 fastened to the floor engaging member by means of the push-fit members 132.Lower portions of the push-fit members 132 extend beyond the through holes 130 on the underside of the base element 120.The floor engaging member 136 defines a plurality of through holes 144 arranged in a circumferential array adjacent the outer edge of the base element floor engaging member 136.The positions of the through holes 144 are such that lower portions of the push-fit members 132 can be received in the through holes 144 when the anchor device is assembled as shown in FIG.", "10.A suspension device 26, similar to that described above can then be arranged so that the toggle 46 is in its non-securing position inserted upwardly through the tubular fastening member 138.When the toggle 46 is received in the cavity 124, it moves to the securing position shown in FIG.", "10, either under its weight, or by being engaged against the inner surface of the cover element 122.When the toggle 46 is in its securing position in the cavity 124, as shown in FIG.", "10, it cannot be removed therefrom via the aperture 121 and, therefore, secures the suspension device 26 to the anchor device 110.The provision of the securing mechanism 27 and the cavity 24, as described above provides the advantage that the height of the anchor devices 0, 0 is considerably less than known anchor devices.", "The height of each of the anchor devices 10, 1 10 shown in the drawings is substantially 30 mm.", "A consequence of this is that the anchor devices 10, 0 are much less likely to be kicked or tripped over by those working on the construction of the floor, which results in less damage to the anchor devices 10, 110, and less likelihood of injury to the workers.", "Various modifications can be made without departing from the scope of the invention.", "For example, FIGS.", "11 and 12 depict an alternative version of the first embodiment of the anchor device 10 shown in FIGS.", "1 to 5.The embodiment shown in FIGS.", "11 and 12 has many of the same features as the first embodiment, and these features have been designated with the same reference numerals as in FIGS.", "1 to 5.The anchor device 10 shown in FIGS.", "11 and 12 differs from the first embodiment in that it has four equi-spaced fingers 228 instead of eight fingers 28.In addition, the fingers 228 have distal end regions 228C that taper outwardly from the second region 228B.", "The distal end regions 228C are connected to a horizontally extending circular flange portion 201, which extends around the fingers 228.The underside 202 of the flange portion 200 engages the form 100 to provide a stable platform for the anchor device 10." ] ]

of solid state memories.", "In FIG.", "1, a computer 1 is directly connected to an SSD storage appliance 2.The SSD storage appliance 2 comprises a plurality of solid state drives (SSDs).", "Three SSDs 3, 4, 5 are shown in FIG.", "1, though it will be appreciated that the appliance 2 may comprise any number of SSDs.", "The SSD 3 is shown in further detail.", "It can be seen that the SSD 3 comprises an SSD controller 6 and a plurality of solid state memories.", "Three solid state memories 7, 8, 9 are shown in FIG.", "1, though it will be appreciated that the SSD 3 may comprise any number of solid state memories.", "The solid state memories 7, 8, 9 are Flash memories, though it will be appreciated that one or more of the solid state memories may be any type of solid state memory, such as EEPROM memories more generally.", "The SSD controller 6 is configured to control the way in which data is written to the solid state memories 7, 8, 9 by abstracting the details of how data is stored on the solid state memories 7, 8, 9 to users of the SSD 3.In the present example, the SSD controller 6 is operable to provide what will be referred to as a “logical disk” representing the physical storage provided by the solid state memories 7, 8, 9.It will be appreciated that in other embodiments, any number of logical disks may be provided by the controller 6.The SSD controller 6 receives read/write requests specifying an address in the logical disk and directs those requests to locations within the solid state memories 7, 8, 9.The SSD controller 6 may perform wear-levelling across the solid state memories 7, 8, 9, and between pages (i.e.", "minimum erasable address ranges) within each solid state memory 7, 8, 9.While the examples described herein are described in terms of “storage” and “disks”, it will be appreciated that the concepts described are equally applicable to other data access semantics.", "For example, it will be appreciated from the teaching herein that the techniques described are equally applicable to “memory” and “address space” data access semantics.", "While “storage” access semantics generally use read/write requests to set up asynchronous transfers of, typically, relatively large amounts (e.g.", "kilobytes or megabytes) of data, “memory” access semantics generally involve synchronous reads/writes of relatively small (e.g.", "64 bytes) amounts of data.", "In the appliance 2 the SSDs 4, 5 are arranged in the same way as the SSD 3, and each provides a respective single logical disk.", "It is to be understood, however, that the SSDs 3, 4, 5 may each be configured differently.", "For example, each SSD within the appliance 2 may have a different storage capacity, use different solid state memories, use different SSD controllers, etc.", "Referring to FIG.", "2, there is schematically illustrated a logical storage space 20 provided by the SSDs 3, 4, 5.The logical storage space 20 comprises three logical disks each provided by a respective one of the SSDs 3, 4, 5.In particular, a first logical disk LD0 is provided by the SSD 3, a second logical disk LD1 is provided by the SSD 4 and a third logical disk LD2 is provided by the SSD 5.As indicated above, while in this example each of the SSDs 3, 4, 5 are similarly arranged to provide logical disks of the same size, it is to be understood that this is not an essential feature.", "The appliance 2 further comprises a host interface layer 10 for facilitating communication between the computer 1 and the appliance 2 over an interface 11.The interface 11 is a PCI Express interface, though it is to be understood that the interface 11 (and therefore the host interface layer 10) may utilise any interface technology.", "For example, in other embodiments, the interface 11 may be Ethernet, Fibre Channel, Inifiniband, etc.", "The appliance 2 is shown connected to the computer 1, though the appliance host interface layer 10 may provide a fan-out function allowing connection to a plurality of computers, illustrated in FIG.", "1 by two additional computers depicted in dashed outline and connecting directly to the host interface 10.A virtualisation layer 12 connects to the host interface 10 via an interface 13.The virtualisation layer 12 connects to each SSDs 3, 4, 5 via respective interfaces 14a, 14b, 14c.", "It is assumed for the purposes of the present example that the interfaces 11, 13 and 14a-c are PCI Express interfaces such that no conversion is performed by the virtualisation layer 12 to convert between the interfaces 14a-c and 13.It is to be understood, however, that the consistency of interface used within the adapter 2 is not an essential feature.", "Indeed, each of the interfaces 11, 13, 14a-c may be different.", "As further examples, the interfaces 14a-c may be SAS or SATA interfaces.", "The virtualisation layer 12 is configured to provide an abstraction of the logical storage provided by the SSDs 3, 4, 5.In particular, the virtualisation layer 12 is configured to create a plurality of what will be referred to herein as “virtual disks”, and to provide access to the virtual disks to the computer 1 (and other computers connected to the appliance 2).", "To create the virtual disks, the virtualisation layer 12 is configured to split the logical storage provided by the SSDs 3, 4, 5 into a plurality of equally sized blocks.", "When the appliance 2 is requested to create a virtual disk by the computer 1, the virtualisation layer 12 creates the storage associated with that virtual disk as a series of virtual blocks, each virtual block being the same size as a logical block.", "A mapping is then created between each block of the newly created virtual disk and the logical block that is to provide the storage for that virtual block.", "The virtualisation layer 12 can therefore create virtual disks with capacities ranging from a single logical block to the entire capacity of the logical storage 20.Referring to FIG.", "3, the logical disks LD0, LD1 and LD2 have been split to each provide ten logical blocks.", "Four virtual disks are provided in a virtual storage space 21.A virtual disk VD0 comprises six virtual blocks, two virtual disks VD1, VD2 each comprises four virtual blocks and a virtual disk VD3 comprises ten virtual blocks.", "Shading of the blocks of the virtual disks VD0-VD3 and the blocks of the logical disks LD0-LD2 indicates, generally, which logical blocks provide storage for the blocks of the virtual disks.", "In FIG.", "3, each block of the virtual disk VD0 is filled with horizontal line shading, each block of the virtual disks VD1 and VD2 is filled with diagonal line shading, while each block of the virtual disk VD3 is filed with vertical line shading.", "Two blocks from the logical disk LD0, and four blocks from the logical disk LD1 are filled with horizontal line shading indicating that these blocks provide the storage for the virtual disk VD0.Three blocks of the logical disk LD0 and one block of the logical disk LD2 are filed with diagonal line shading indicating that these blocks provide the storage for both of the virtual disks VD1, VD2.Four blocks of the logical disk LD1 and six blocks of the logical disk LD2 are filled with vertical line shading indicating that these blocks provide the storage for the virtual disk VD3.Each of the Tables 1 to 4 below show a mapping table for a particular one of the virtual disks, VD0 to VD3.The mapping tables shown in Tables 1 to 4 may be stored and maintained by the virtualisation layer 12.TABLE 1 Mapping table for virtual disk VD0 Virtual Disk:Block Logical Disk:Block VD0:0 LD0:0 VD0:1 LD0:1 VD0:2 LD1:0 VD0:3 LD1:1 VD0:4 LD1:2 VD0:5 LD1:3 TABLE 2 Mapping table for virtual disk VD1 Virtual

LD2:8 With reference to the Tables 2, 3 it can be seen that the virtual disks VD1 and VD2 are provided by the same logical blocks, and that the mappings between those logical blocks and the virtual blocks of the virtual disks VD1 and VD2 are also the same.", "That is, both the virtual blocks VD1:0 and VD2:0 map to the same logical block (LD0:2), both virtual blocks VD1:1, VD2:1 map to the same logical block (LD0:3), etc.", "It is to be understood however, that a mapping between virtual blocks of two virtual disks provided by the same logical blocks need not be identical.", "For example, the virtual blocks VD1:1, VD2:1 may be mapped to different ones of the logical blocks providing the virtual disks VD1, VD2 (LD000:2, LD0:3, LD0:4, LD2:1).", "Upon receipt of a read/write request from the computer 1 specifying one or more virtual blocks of a particular virtual disk, the virtualisation layer 12 determines the corresponding logical block(s) that provides the storage for the specified virtual block(s).", "The virtualisation layer 12 then provides the read/write request to the SSD controller of the appropriate SSD 3, 4, 5 which handles the operation of the read/write request with respect to the underlying physical storage provided by the solid state memories of the SSD.", "A read/write request may comprise a sequential, contiguous block of addresses.", "For example, a read/write request may be defined by a ‘start address’ and a ‘length’.", "Such read/write requests may therefore span a plurality of virtual blocks.", "It will be appreciated from the above that the plurality of virtual blocks specified in a read/write request may each be mapped to logical blocks provided by the same logical disk but which are not contiguous, or may each be mapped to logical blocks provided by different logical disks.", "In such cases, the read/write requests may be split into a plurality of read/write requests at the “boundary” of each virtual block.", "That is, if, for example, a read/write request specifies an address range that spans three virtual blocks mapped to three non-contiguous logical blocks (either within the same logical disk or different logical disks), the read/write request may be split into three separate read/write requests.", "Such splitting may be performed by the virtualisation layer 12.While a read/write request may specify a plurality of virtual blocks, for clarity of description herein it is assumed that each read/write request indicates a single virtual block.", "The mapping between logical blocks of the logical storage space 20 and the virtual blocks of the virtual storage space 21 shown in FIG.", "3 is merely exemplary.", "Indeed, the mapping may take any form.", "That is, any virtual block may be mapped to any one of the logical blocks, and, as shown in FIG.", "3, the mapping may be a many-to-one mapping such that many virtual blocks may be mapped to a single physical block.", "Wear on an SSD is primarily determined by the number and the characteristics of erasure and write operations performed on that SSD.", "As noted above, each SSD controller (such as the controller 6 of the SSD 3) may perform wear levelling to ensure that wear is levelled across the solid state memories (such as the solid state memories 7, 8, 9) within the SSD.", "However, while the controller 6 may spread erasure and write operations across the solid state memories 7, 8, 9 within the SSD 3 (and between pages of a particular solid state memory), if for example, one or more logical blocks within the virtual disk VD1 that are mapped to blocks of the logical disk LD0 are particularly heavily written to by the computer 1, the logical disk LD0 (and therefore the SSD 3) may experience heavy wear in comparison to the other logical disks LD1 to LD2 (and therefore the SSDs 4, 5).", "Such concentration of wear on a single SSD may be undesirable.", "Because the virtualisation layer 12 is responsible for the mapping between logical blocks and virtual blocks, the individual SSD controllers of the SSDs 3, 4, 5 are unable to control which SSD data is written to in response to use of a particular virtual block by the computer 1.The virtualisation layer 12 is therefore configured to manage wear across the SSDs 3, 4, 5 according to a desired wear policy.", "Referring to FIG.", "4, the virtual disk VD1 and the logical disks LD0.LD2 are shown.", "As indicated in the Table 2 above, the virtual block VD1:0 is mapped to the logical block LD0:2, while the virtual block VD1:1 is mapped to the logical block LD0:3.Both the virtual block VD1:0 and the virtual block VD1:1 are high-wear blocks (i.e.", "the virtual blocks VD1:0 and VD1:1 have a greater contribution to the overall wear of the SSDs to which they are currently mapped).", "That is, in the example of FIG.", "4, the virtual blocks VD1:0 and VD1:1 contribute more to wear on the SSD 3 than does the virtual block VD1:2.The determination as to which virtual blocks are high-wear blocks may be based upon an amount of data that is written to those virtual blocks.", "The virtualisation layer 12 may track the amount of data that is written per virtual block and use this as an indication of the contribution of that block to SSD wear.", "The virtualisation layer 12 may utilise other information in determining whether a particular virtual block is a high-wear block.", "For example, the virtualisation layer 12 may query the SSD controller of each SSD with regard to the way in which SSD wear levelling is performed by that controller.", "Alternatively or additionally, the virtualisation layer 12 may utilise an approximation of the wear levelling algorithm performed by one or more of the SSD controllers to estimate how a write to a particular block affects the wear on an SSD controlled by that controller.", "Further, performing many frequent small writes can cause more wear than writing the same amount of data in fewer large writes.", "As such, the virtualisation layer 12 may also track and utilise data indicating the size distribution of write operations.", "Additionally, misaligned writes may cause more wear than writes aligned with word boundaries.", "As such, the virtualisation layer 12 may utilise data indicating the alignment of writes relative to the architectural boundaries of an SSD.", "In general, it will be appreciated that any appropriate data may be used by the virtualisation layer 12 in determining whether a block constitutes a high-wear block.", "Having determined that a virtual block is a high-wear block, this information is used to implement a particular wear policy.", "For example, a wear-levelling policy may be implemented in which the virtualisation layer updates the mapping between logical storage 20 and physical storage 21 in order to equally spread any high-wear blocks across the SSDs 3, 4, 5.A wear-levelling policy can help ensure that each SSD 3, 4, 5 wears evenly such that each SSD 3, 4, 5 fails near to the same time.", "As another example, a wear-concentration policy may be implemented in which the virtualisation layer 12 concentrates high-wear blocks on relatively few SSDs or a single SSD.", "In this way, one or more SSDs can be caused to wear out before other SSDs in the appliance 2 so that not all SSDs within the appliance 2 fail at the same time.", "Where two or more SSDs use different technology such that at least one SSD has a greater endurance than the other SSDs (i.e.", "can perform a larger number of erasures and writes per block before failure of that block), the virtualisation layer 12 can concentrate high-wear blocks onto those SSDs with a greater endurance.", "It is to be understood that other wear policies or any combination of wear policies may be used.", "The contribution that any particular block makes to the wear on an SSD may change with time.", "The virtualisation layer 12 is therefore arranged to update the mapping between the logical address space 20 and the virtual address space 21.Referring again to FIG.", "4, a solid arrow from the virtual block VD1:1 to the logical block LD0:3 indicates the current mapping between the virtual block VD1:1 and the logical block LD0:3.A dashed arrow from the virtual block VD1:1 indicates a new mapping between the virtual block VD1:1 and a logical block LD2:2.Table 5 below illustrates the state of the mapping table for the virtual disk VD1 after the re-mapping illustrated in FIG.", "4.After the mapping change, each of the logical disks LD0 and LD2 comprise a single high-wear block.", "The re-mapping shown in FIG.", "4 may therefore be considered to be an example of a wear-levelling policy.", "TABLE 5 Updated mapping table for virtual disk VD1 Virtual Disk:Block Logical Disk:Block VD1:0 LD0:2 VD1:1 LD2:2 VD1:2 LD0:4 VD1:3 LD2:1 In order to change the mapping between the virtual block VD1:1 and the logical block LD0:3 so that the virtual block VD1:1 is mapped to the logical block LD2:2, the data stored within the logical block LD0:3 is copied to the logical block LD2:2.Depending upon the size of the blocks, this may take a significantly long time compared to the rate at which data is written to and read from the appliance 2 by the computer 1.Generally, read activity can continue to be directed to the logical block LD0:3 until the copy operation is complete and the mapping has been updated.", "Write activity may be handled as described in the examples below with reference to FIGS.", "5 to 9 to mitigate problems that may be caused when data is written to a virtual block that is currently undergoing a re-mapping operation.", "Where a mapping between logical blocks and the virtual blocks of the virtual disk VD2 is to be maintained as identical to the mapping between logical blocks and the virtual blocks of the virtual disk VD1 (as shown in Tables 2, 3), the mapping table for the virtual disk VD2 may also be updated following the re-mapping operation for the virtual disk VD1.It is to be understood that a “re-mapping operation” for a particular virtual block of a particular virtual disk generally involves copying data from a logical block to which the particular virtual block is currently mapped to a new logical block, ensuring that the new logical block is correct (taking account of any intervening write operations), and updating the mapping table for the particular virtual disk so that the particular virtual block is mapped to the new logical block.", "Re-mapping operations may need to be performed under different conditions.", "For example, it may be possible to “stall” the whole of the appliance 2, or only the current logical block, to prevent write operations to the current logical block for a long enough time to allow a re-mapping operation to be effected without detrimental delay to computers wishing to use the appliance 2.In other examples, however, stalling of the appliance 2 or the current logical block is either not desirable, or infeasible.", "In examples where stalling of the appliance 2 for an entire mapping update is not desired or infeasible, mapping updates are executed while the appliance 2 is fully functioning (“live”).", "That is, in some examples, mapping updates are executed while computers are reading and writing data to/from the virtual disks provided by the appliance 2.In general terms, and as described in more detail below with reference to FIG.", "6, in one example copy operation, a current logical block is sub-divided into a plurality of sub-blocks.", "The number of sub-blocks may be selected based on any appropriate criteria.", "As an example, the current block may be sub-divided into one-thousand-twenty-four sub-blocks.", "Data is then copied from the current logical block to the new logical block one sub-block at a time.", "It is to be understood that the sub-division of a logical block into a plurality of sub-blocks need not require any processing to be carried out on the logical block itself.", "Rather, the sub-division is a logical sub-division from the point of view of the virtualisation layer 12.As the virtual block represents a mapping between a view of storage visible to the computer 1 and the logical storage provided by the SSDs, concepts described with respect to a virtual block may be considered to apply equally to the logical block to which it is mapped.", "For example, in considering the sub-division of a logical block, any virtual block to which that logical block is mapped may be considered to be so sub-divided.", "Similarly, when it is described herein that a virtual block is the subject of a re-mapping operation, it may of course equally be said that the logical block to which the virtual block is mapped is subject to the same re-mapping operation.", "Referring to FIG.", "5, there is illustrated processing that may be carried out by the appliance 2 in response to receipt of a write request.", "At a step S1 a write request is received (e.g.", "from the computer 1) comprising data and an address of a virtual block to which the data is to be written.", "At a step S2 the virtualisation layer 12 determines the logical block to which virtual block specified in the write request corresponds.", "Processing passes to step S3 at which the received data is written to the identified logical block (i.e.", "is sent to the SSD that provides the logical block for writing to a solid state memory in accordance with the policies of the SSD controller).", "From step S3, processing passes to step S4 at which it is determined whether a re-mapping operation is currently underway that includes the logical block to which data was written at step S3.If it is determined that a re-mapping operation is currently underway, processing passes to step S5 at which any sub-blocks that have been affected by the write operation and which have already been copied to the new logical block are marked as ‘dirty’.", "For example, a flag may be set within a record of each sub-block maintained by the virtualisation layer 12.Processing passes from step S5 to end at step S6.If, on the other hand, it is determined at step S4 that the logical block is not currently the subject of a re-mapping operation, processing passes directly from step S4 to end at step S6.The processing of FIG.", "5 therefore allows a determination to be made as to which sub-blocks of a logical block have been affected by a write request that occurs during a re-mapping operation.", "Referring now to FIG.", "6, an example of processing carried out to perform a re-mapping operation is now described.", "At a step S10, a virtual block to be re-mapped is selected, as discussed above.", "A new logical block to which the selected virtual block is to be mapped is also selected.", "An indication is stored that the virtual block is currently subject to a mapping operation (for use at step S4 of FIG.", "5).", "At step S11 the current logical block and the new logical block are divided into a plurality of sub-blocks.", "At step S12 the first sub-block of the plurality of sub-blocks is copied to the corresponding sub-block of the new logical block.", "At step S13 it is determined whether any of the plurality of the sub-blocks remain to be copied to the new logical block.", "If it is determined at step S13 that there are un-copied sub-blocks, processing passes to step S14 at which the next un-copied sub-block is copied to the new logical block.", "Processing passes from step S14 to step S13.Processing therefore loops between steps S13 and S14 until each sub-block has been copied to the new logical block.", "If it is determined at step S13 that all sub-blocks have been copied to the new logical block, processing passes from step S13 to step S15, at which it is determined whether there are any blocks marked “dirty” (by the processing of step S5 of FIG.", "5) that have not been copied.", "That is, it is determined at step S15 whether, after being copied by the processing of steps S12 to S14, new data has been written to any of the sub-blocks, the new data having yet to be copied to the new logical block.", "If it is determined at step S15 that there are no un-copied “dirty” sub-blocks, this indicates that the new logical block is correct and processing passes from step S15 to step S16 at which the mapping is updated.", "After the processing of step S16, therefore, the selected virtual block is mapped to the new logical block and the indication that a re-mapping is underway is cleared.", "If, on the other hand, it is determined at step S15 that there are un-coped “dirty” sub-blocks, the new logical block will not be correct, such that the mapping cannot be updated.", "Processing therefore passes from step S15 to step S17 at which it is determined whether a maximum number of re-copy iterations (steps S15, S17, S18 and S19) has occurred.", "If it is determined that a maximum number of re-copy iterations has not occurred, processing passes from step S17 to step S18 at which the next “dirty” sub-block is copied to the appropriate sub-block in the new logical block.", "Processing passes from step S18 to step S19 at which the re-copied block is marked as “clean” (i.e.", "the dirty flag is cleared) to indicate that the sub-block has been re-copied with the latest written data.", "Processing passes from step S19 to step S15 at which it is determined whether there are any remaining un-copied dirty sub-blocks.", "Processing loops between steps S15, S17, S18 and S19 until either there are no remaining dirty sub-blocks (such that processing ends at step S16) or until it is determined at step S17 that a maximum number of re-copy iterations has been performed.", "Where the rate at which new data is written to the selected virtual block is lower than the rate at which the data is copied between the old logical block and the new logical block, the re-copy iterations will result in the number of dirty sub-blocks tending towards zero.", "If, however, the rate at which new data is written to the selected virtual block is near to or exceeds the rate at which data is copied, a substantial number of “dirty” sub-blocks may remain even after many re-copy iterations.", "The maximum number of re-copy iterations may be defined by a user of the appliance 2 in dependence upon application specific requirements.", "For example, the maximum number of Iterations may be selected with regard to an acceptable time in which performance of the appliance 2 may be reduced as a result of the re-copy operation as balanced against a desire to implement the selected wear-policy.", "For example, a lower number of re-copy iterations may be selected where it is desired to reduce the length of time for which the performance of the appliance 2 is reduced.", "If it is determined at step S17 that a maximum number of iterations has been reached, processing passes from step S17 to step S20.At step S20 it is determined whether the number of remaining “dirty” sub-blocks is below a predetermined threshold.", "If it is determined that the number of “dirty” sub-blocks is below the predetermined threshold, processing passes to step S21 at which further writes to the virtual block are prevented until the re-mapping has completed.", "Processing passes from step S21 to step S18.During a “writes prevented” state the maximum number of allowed re-copy iterations may be set such that a sufficient number of re-copy iterations complete to allow the remaining dirty sub-blocks to be copied.", "In other embodiments, step S17 may be ignored while in the “writes prevented” state.", "In other alternative embodiments, the maximum number of re-copy iterations may be set to a desired number and the processing of step S17 carried out as described above.", "The predetermined threshold against which the number of “dirty” sub-blocks is judged at step S20 may be set by a user in dependence upon application specific requirements.", "For example, the predetermined threshold may be set at a level at which the estimated time to copy the remaining dirty sub-blocks is acceptably short as judged, for example, against application-specific requirements.", "If, on the other hand, it is determined at step S20 that the number of dirty sub-blocks is above the predetermined threshold, processing

the new logical block.", "At step S22 it is determined whether the re-mapping process is to be aborted.", "If it is determined at step S22 that the re-mapping process is to be aborted, processing passes from step S22 to end at step S23.A message may be provided to a user or administrator of the appliance 2 that the re-mapping process has failed.", "If, on the other hand, it is determined at step S22 that the re-mapping process is not to be aborted, processing passes from step S22 to step S24 at which the dirty block threshold of step S20 is increased, and the maximum number of allowed

to FIG.", "6 provides one example of a way in which a current logical block may be copied to a new logical block.", "It will be appreciated that modifications to the processing of FIG.", "6 may be made.", "For example, if it is determined that the maximum number of re-copy iterations has been exceeded, and the number of dirty sub-blocks is not below a predetermined threshold, other mitigation strategies may be implemented than those implemented at steps S22 and S24.For example, where possible, instead of preventing writes to the current logical block entirely, the rate at which data is copied to the new logical block may be increased.", "That is, in some embodiments, the rate at which data is initially copied to the new logical block may be limited in order to prevent the copy process from adversely affecting the normal operation of the appliance 2.Where this is the case, such limitations may be eased or removed in order to allow the copy process to complete.", "In other embodiments, rather than determining at step S17 whether a maximum number of re-copy iterations have occurred, the virtualisation layer may track the number of remaining dirty-sub blocks.", "It may then be determined whether the number of un-copied dirty sub-blocks is reducing in each iteration of steps S15, S17, S18, S19, or over predetermined periods of time.", "The processing of FIG.", "6 (and the processing of FIG.", "8 described below) may be performed in parallel in order to copy multiple blocks at the same time.", "Such parallel processing may, however decrease the rate at which each copy operation is performed, which may in turn increase the number of dirty sub-blocks which need to be recopied.", "As such, the number of re-copy operations allowed to execute in parallel may be selected by a user or administrator of the appliance 2 in dependence upon application-specific requirements.", "An alternative example of a way in which data may be copied between a current logical

intercepting device may be configured to intercept data packets sent from the computer 1, identify whether that data packet is intended to be sent to the appliance 33, and if so to modify that data packet so that it is directed to device 39 by the switch 34.Similarly, a corresponding intercepting device may be provided between the appliance 33 and the switch 34 to identify data packets sent from the appliance 33 destined to the computer 1, 31 and to re-direct such data packets to the switch 34.Alternatively, the computers 1, 31 and/or the appliance 33 may be configured to direct data packets

blocks are high-wear blocks.", "In some embodiments, the identification of high-wear blocks may be performed at each respective computer.", "For example, interface driver software within each computer

quantities of data, writes to most frequently, the size of the write operations, etc.", "As such, each computer 1, 31 may be arranged to determine which of the blocks to which it has access are high-wear blocks, and to provide indications of high-wear blocks to the virtualisation layer 12, or the device 39.In this way, additional speed benefits may be obtained through distribution of processing.", "Further, there may be a large number of virtual blocks within the virtual storage space 21 such that the amount of data that is required to be stored in order to identify high-wear blocks may be substantial.", "By performing identification of high-wear blocks at the computers 1, 31, the storage requirements for this data may be distributed.", "Further, resources already provided by the computers 1, 31 may be utilised, obviating the need to provide additional resources in an appliance or a virtualisation controller.", "As an additional example of distribution of the processing performed by the virtualisation layer 12, splitting of read/write requests that indicate an address range in the virtual address space 21 spanning multiple virtual blocks may be performed at one or both of the computers 1, 31.That is, as described above, a read/write request may comprise a sequential, contiguous block of addresses that span a plurality of virtual blocks.", "Splitting the

be replaced, the data contained on that SSD may be copied to blocks on one or more of the other SSDs.", "For example, if the SSD 3 were to be removed, the data stored on the SSD 3 may be copied to logical blocks of logical disks provided by either or both of the SSDs 4, 5.Similarly, after replacement of the SSD 3 with a new SSD, the data copied to the SSDs 4, 5 may then be copied to the newly

performed to copy all data stored on an SSD, and that each block copy operation may copy data to logical blocks on different SSDs.", "For example, with reference to FIG.", "1, if the SSD 3 was to be removed from the appliance 2, some data stored on the logical disk LD0 (provided by the SSD 3) may be copied to the logical disk LD1 (provided by the SSD 4) while other data may be copied to the logical disk LD2 (provided by the SSD 5).", "In addition to use for implementation of a wear policy, therefore, the block-copy operations described above may also be used to provide a copy mechanism to allow hot-swapping of SSDs from an appliance or logical appliance.", "It will further be appreciated that the block copy operations described above may be used for storage devices other than solid state memories and SSDs.", "Mappings between virtual blocks and logical blocks may also be selected and managed so as to optimize characteristics other than endurance characteristics, in accordance with the embodiments described above.", "Indeed, it will be appreciated that mappings between virtual blocks and logical blocks may be selected to optimize any desired characteristic.", "As a further example only, mappings may be created in order to provide virtual disks with desired latency characteristics.", "For example, where SSDs within an appliance (or a logical appliance) provide different latencies, it may be desired to provide a virtual disk with a particular latency characteristic.", "For example, it may be desired to provide at least one low latency virtual disk.", "The virtual blocks of such a virtual disk (which could be referred to as “low latency virtual blocks”) may be mapped to logical blocks provided by those logical disks with the suitably low latencies (which could be referred to as “low latency logical blocks”).", "As a further example, where each SSD within an appliance (or logical appliance) is of the same type, one or more of the logical disks may be mapped to virtual disks used by particular applications (or by a single application).", "By restricting the ability of other applications to use logical disks through the mapping between virtual disks and logical disks, the performance of some applications can be improved.", "A further example of a characteristic that may be optimized through the choice of mapping between logical disks and virtual disks is that of resilience.", "For example, mappings may be selected so as to provide a “mirror pair” of virtual disks, each virtual disk within the mirror pair being located on physically distinct SSDs.", "Alternatively, a virtual disk may be mapped to a first logical disk, In this way, the possibility of data loss as a result of failure of one of those SSDs is mitigated.", "While specific embodiments have been described above, it will be appreciated that the invention may be practiced otherwise than as described.", "The descriptions above are intended to be illustrative, not

described with respect to one embodiment may be combined with the features, components, and/or steps described with respect to other embodiments of the present disclosure to form yet another embodiment of a device, system, or method according to the present disclosure even though such a combination is not explicitly shown.", "Further, for the sake of simplicity, in some instances the same reference numerals are used throughout the drawings to refer to the same or like parts.", "The present disclosure is generally related to optical sensing systems and methods, more particularly to circuits, systems, and methods for compensating a light source of an optical sensing system to work under a range of operation temperatures.", "An object of the present disclosure is to provide a temperature-compensated light source whose radiant energy output remains generally constant across a range of operation temperatures.", "Another object of the present disclosure is to provide an LED-drive circuit that can work with most existing LEDs through a calibration procedure.", "Once calibrated, the LED-drive circuit is operative to produce a current that complements the given LED such that the LED's output power remains generally constant when ambient temperature changes.", "Yet another object of the present disclosure is to provide a calibration method that can be implemented in an optical sensing system to achieve the aforementioned temperature compensation.", "Referring to FIG.", "1, shown therein is a schematic partial view of an optical sensing system 10 constructed according to an embodiment of the present disclosure.", "The optical sensing system 10 includes an LED 12 whose anode 11 is coupled to a supply voltage VDD and whose cathode 13 is coupled to a current source 28 through a switch 30 (further discussed later).", "A forward current ILED goes through the LED 12 and causes it to produce a light (or radiant energy).", "The LED 12 may produce visible light or invisible light, including ultraviolet light and infrared light.", "The LED 12 may comprise any suitable semiconductor materials such as gallium arsenide (GaAs), gallium phosphide (GaP), aluminum gallium arsenide (AlGaAs), gallium arsenide phosphide (GaAsP), indium gallium nitride (InGaN), aluminum gallium phosphide (AlGaP), and aluminum gallium indium phosphide (AlGaInP).", "The optical sensing system 10 further includes a photodiode 14 whose anode 15 is connected to ground (Vss) and whose cathode 17 is connected to a switch (e.g., a reset switch) which is connected to the supply voltage VDD.", "The photodiode 14 receives at least a part of the radiant energy of the LED 12, for example, through reflection off a surface, diffraction by a medium, or transmission through a medium.", "In response, the photodiode 14 produces a current from its cathode 17 to its anode 15.This current is sensed by a detection circuit 16 for further processing.", "A characteristic of the LED 12 is that if the current ILED remains constant, its radiant energy output decreases when ambient temperature increases.", "Such variation with ambient temperature affects the ability of the photodiode 14 and the detection circuit 16 to detect the radiant energy reliably.", "As a result, the sensitivity of the photodiode 14 is limited by how much variation there is in the LED 12's radiant energy output.", "For applications that operate across a wide range of ambient temperatures (e.g., commercial grade temperature range from 0° C. to 70° C., industrial grade temperature range from −40° C. to 85° C., or military grade temperature range from −55° C. to 125° C.), it is highly desirable to keep the LED 12's radiant energy output constant or generally constant (e.g., within few percent) across the operation temperatures.", "The present disclosure provides solutions to such problem as further discussed below.", "Still referring to FIG.", "1, the optical sensing system 10 further includes a module 18 that is a temperature-dependent current generator and a module 20 that is temperature-independent current generator.", "The module 18 is operative to produce a current IS.", "The

embodiment, the current IS increases (or decreases) first order linearly when ambient temperature increases (or decreases).", "In the present disclosure, the term “first order linearly” means that the current IS can be modeled in equation (1) below as a linear equation of absolute temperature T and any second or higher order effects of temperature T can be ignored when temperature is within a defined range such as within an expected operating range.", "The same definition of “first order linearly” applies to the discussion of other variables and circuit parameters including voltage, current, power, and resistance.", "IS=mT+I0, where m and I0 are constant and m>0 (1) In contrast, the current IR is first order independent of ambient temperature, i.e., it remains relatively constant across an operation range of ambient temperatures and any second or higher order effects of ambient temperature can be ignored.", "The optical sensing system 10 further includes a current adder (or a current-mode adder) 22.The current adder 22 is operative to produce a current IB which is a weighted sum of the currents IS and IR.", "In the present embodiment, the current adder 22 applies a first weight WS to the current IS and a second weight WR to the current IR.", "Therefore, the current IB can be expressed in equation (2) below: IB=WSIS+WRIB (2) In the present embodiment, the weights WS

to derive a proper IB which complements the temperature-dependence of LED 12.In other words, it causes the radiant energy output of LED 12 to remain generally constant across the operation range of ambient temperatures.", "Once proper values of WS and WR are found (or calibrated), such values may be stored in a non-volatile memory (e.g., as digital bits in control unit 24).", "This provides advantages that the optical sensing system 10 can resume proper operation after power-off and power-on without a need of repeating the calibration procedure.", "Still referring to FIG.", "1, in the present embodiment, the optical sensing system 10 further includes a current multiplier 26 that multiplies the current IB with a control vector ACTRL and produces a current IA as follows: IA=ACTRLIB (3) The control vector ACTRL is provided by the control unit 24 in the present embodiment.", "In applications, a user may manually or automatically step through a set of values of the ACTRL, which in turn produces a set of optical output power at the LED 12.This may be used for calibrating the LED 12 and the photodiode 14 to find a desirable working condition for the optical sensing system 10.In an embodiment, once the LED 12 and the photodiode 14 are calibrated at a nominal temperature (e.g., at room temperature), the value of ACTRL is stored in a non-volatile memory and is used by the optical sensing system 10 in subsequent operations.", "In an embodiment, the current source 28 is a current mirror that copies the current IA to the electrical path of the LED 12.In effect, ILED equals to IA when the switch 30 is turned on (or closed).", "The temperature-dependence of IA complements that of the LED 12.In an embodiment, the switch 30 is controlled to turn on and off to pulse the LED 12 periodically.", "For example, the LED 12 may be turned on for 200˜300 nanoseconds (ns) with a period of 1 to 2 microseconds (μs).", "Referring to FIG.", "2A, the optical sensing system 10 further includes a bandgap voltage reference 19 which is operative to provide a voltage potential VR.", "The voltage VR is first order independent of ambient temperature.", "The voltage VR is supplied to the current generator 18 (FIGS.", "2A and 2B) and the current generator 20 (FIG.", "3) as a reference voltage.", "Still referring to FIG.", "2A, an embodiment of the temperature-dependent current

45 is inversely proportional to ambient temperature in the first order.", "In other words, the voltage VBE can be modeled as a linear equation (4) of absolute temperature T and any second or higher order effects of temperature T can be ignored when temperature is within a defined range such as within an expected operating range.", "VBE=−nT+V0, where n and V0 are constant and n>0 (4) The current generator 18 further includes resistors R1 and R2 that are connected in series between the reference voltage VR and the ground VSS.", "The resistors R1 and R2 are coupled to a common node 32.Resistance values of the resistors R1 and R2 are first order independent of ambient temperature.", "Therefore, a voltage potential V32 at the node 32 is first order independent of ambient temperature and can be expressed in equation (5) below.", "V32=kVR,where k=R2/(R1+R2) and 0<k≤1 (5) The current generator 18 further includes an operational amplifier X1.The operational amplifier X1

directed to a temperature compensation circuit for a light source, such as a light emitting diode (LED).", "The light source has a characteristic that, if a current flowing through the light source remains constant, the light source's radiant energy output decreases when ambient temperature increases.", "The temperature compensation circuit includes first means for sourcing a first current that

swing the catch rod 518 out of the recessed region 533.According to one aspect, the lever arm is pulled rearward first before actuating rod 516, as otherwise the catch rod may next exit recessed region 533.These actions may function to cause ends 510 of the linking members to move rearward to and the left from the perspective of FIG.", "33, as seen by arrow of numeral 481, thereby enabling catch rod 518 to dislodge from recessed regions 533 of the hook members 526.Thus, actuation of the second end of the linking member enables the elongate member to be selectively removed from the hook

tread, the structure of which is suitably adapted to the underlying surfaces and weather conditions to be expected.", "In a manner known per se, the tread of the pneumatic vehicle tire transitions at both sides into sidewalls, the end of which is formed in each case by a tire bead.", "The tire bead serves for the air-tight fixing of that part of the pneumatic vehicle tire which is made up of different rubber mixtures to a wheel rim of a vehicle wheel equipped with the pneumatic vehicle tire.", "Here, in a manner which is likewise known, the vehicle wheel rim has, correspondingly to the tire bead, a wheel-rim edge against which the tire bead sealingly bears when the tubeless pneumatic vehicle tire is filled with compressed air.", "The pneumatic vehicle tire consequently has an air cavity in which a foamed material layer made of polyurethane or polyethylene is present, which is fastened to the inner surface situated opposite the tread of the pneumatic vehicle tire.", "Pneumatic vehicle tires must nowadays not only transmit the kinetic energy generated by the motor vehicle to the underlying surface in an optimum manner at all times under changing environmental conditions, but must increasingly also satisfy elevated demands with regard to comfort.", "Here, the rolling noise of the pneumatic vehicle tire also plays a significant role, which noise is generated by the vibration of the air when the latter is compressed as the pneumatic vehicle tire is pressed against the road surface.", "The rolling noise is transmitted from the pneumatic vehicle tire to the wheel hub before possibly passing via the steering system and the suspension arrangement into the passenger compartment.", "Exposure to the rolling noise generated during driving is perceived as disturbing not only within but also outside the motor vehicle, which is of increasing significance for example in cities.", "The rolling noise can be significantly reduced by means of technology which is already known and which is already in use in some motor vehicles.", "Here, a foamed material is used which is arranged in the pneumatic vehicle tire and which is commonly referred to as “absorber”, and which is attached by means of an adhesive to the inner surface of the tread.", "The structure of this foamed material, which is generally made of foamed polyurethane (PU) or polyethylene (PE), is maintained even in the event of extreme temperature fluctuations.", "Polyurethanes are plastics or synthetic resins which form from the polyaddition reaction of dialcohols or polyols with polyisocyanates.", "Depending on the type of motor vehicle, the speed thereof and the road surface, it is presently possible by means of the stated sound reduction measures to achieve reductions in vehicle noise in the

vehicle tire.", "Pneumatic vehicle tires must nowadays not only transmit the kinetic energy generated by the motor vehicle to the underlying surface in an optimum manner at all times under changing environmental conditions, but must increasingly also satisfy elevated demands with regard to comfort.", "Here, the rolling noise of the pneumatic vehicle tire also plays a significant role, which noise is generated by the vibration of the air when the latter is compressed as the pneumatic vehicle tire is pressed against the road surface.", "The rolling noise is transmitted from the pneumatic vehicle tire to the wheel hub before possibly passing via the steering system and the suspension arrangement into the passenger compartment.", "Exposure to the rolling noise generated during driving is perceived as disturbing not only within but also outside the motor vehicle, which is of increasing significance for example in cities.", "The rolling noise can be significantly reduced by means of technology which is already known and which is already in use in some motor vehicles.", "Here, a foamed material is used which is arranged in the pneumatic vehicle tire and which is commonly referred to as “absorber”, and which is attached by means of an adhesive to the inner surface of the tread.", "The structure of this foamed material, which is generally made of foamed polyurethane (PU) or polyethylene (PE), is maintained even in the event of extreme temperature fluctuations.", "Polyurethanes are plastics or synthetic resins which form from the polyaddition reaction of dialcohols or polyols with polyisocyanates.", "Depending on the type of motor vehicle, the speed thereof and the road surface, it is presently possible by means of the stated sound reduction measures to achieve

present disclosure generally relates to heating, ventilation, and air-conditioning (HVAC) systems for electrically-powered vehicles (EVs) such as battery electric vehicles (BEVs), hybrid electric vehicles (HEVs), and plug-in hybrid electric vehicles (PHEVs), and more specifically, relates to HVAC systems for EVs that assist in reducing battery power losses associated with vehicle heating.", "BACKGROUND Electrically-powered vehicles (EVs), such as hybrid electric vehicles (HEVs), plug-in hybrid vehicles (PHEVs), and battery electric vehicles (BEVs), have many advantages over vehicles powered by internal combustion engines (ICEs).", "For example, EVs may be more energy efficient and more environmentally friendly as they produce fewer emissions.", "An EV may include an electric motor for driving the gearbox and wheels, and the electric motor may be powered by batteries that may be recharged by plugging the vehicle into an electrical power source external to the vehicle, such as an electric outlet.", "EVs are associated with a driving range which is the distance that the EV may travel before the batteries are depleted and recharging is required.", "For example, driving ranges for current EVs may be on the order of about 80-300 miles.", "A plug-in hybrid electric vehicle (PHEV) is a type of EV that includes a small ICE and a fuel tank in addition to the electric motor and batteries.", "For example, the internal combustion engine may combust fuel to drive the vehicle at high speeds, such as on freeways or open roads, while the electric motor may drive the vehicle on city streets.", "However, unlike ICE-powered vehicles in which heat from the ICE may be tapped to heat the passenger cabin, EVs may not have an ICE to use as a heat source and so require auxiliary heating sources.", "For example, some heating, ventilation, and air-conditioning (HVAC) systems in EVs use electrically-powered heaters that rely on battery power.", "The power load on the batteries to support the energy needs of the HVAC system may significantly reduce the driving range of the EV.", "In particular, substantially more battery power is needed to heat the passenger cabin up from a cold temperature to a warm temperature than is needed to maintain the passenger cabin at the warm temperature.", "To reduce battery power losses associated with initial heating, many EVs allow the driver to program the vehicle to pre-condition the passenger cabin to a comfortable temperature while the vehicle is parked and recharging at the electrical outlet.", "As a result, the energy requirement to heat the passenger cabin up from a cold temperature is supplied by the electric outlet, thereby reducing the power load on the batteries.", "In another effort to reduce the power load on EV batteries for cabin heating, U.S. Patent Application Publication No.", "2014/0208789 discloses the use of a phase change material (PCM) positioned about the vehicle battery to store heat from the battery during charging.", "In addition, a coolant circuit takes heat from PCM to heat the passenger cabin while driving.", "While effective, further heating system improvements for EVs are still wanting.", "Clearly, there is a need for improved HVAC designs for EVs that reduce power loads on the batteries.", "SUMMARY In accordance with one aspect of the present disclosure, a heating, ventilation, and air-conditioning (HVAC) system for an electrically-powered vehicle (EV) having an electric motor powered by at least one battery is disclosed.", "The HVAC system may comprise a blower, a conduit configured to carry air from the blower to vents leading to a passenger cabin of the EV, and an electric heater positioned in the conduit and configured to heat the air.", "The HVAC system may further comprise a thermal reservoir heater positioned in the conduit and including a thermal storage component configured to heat the air without using power from the battery.", "In another refinement, the EV may be configured to operate in charging mode during which the electric motor is off and the battery is charging at an electric outlet, and in driving mode during which the electric motor is operational and is not connected to the electrical outlet.", "The thermal storage component may be configured to store heat while the EV is in charging mode.", "In another refinement, the thermal storage component may be further configured to release the stored heat while the EV is in driving mode.", "In another refinement, the thermal storage component may be a phase change material (PCM) configured to undergo a heat-absorbing phase change while the EV is in charging mode, and a heat-releasing phase change while the EV is in driving mode.", "In another refinement,

heater to the PCM may cause the PCM to undergo the heat-absorbing phase change.", "In another refinement, the electric heater and the second electric heater may be separate zones of a single heater.",

refinement, the thermal reservoir heater may be configured to heat the air while the EV is in driving mode.", "In another refinement, the electric heater may be further configured to heat the air while the EV is in driving mode after the PCM has completed the heat-releasing phase change.", "In another refinement, the electric heater and the second electric heater may be positive temperature coefficient (PTC) heaters.", "In another refinement, the second electric heater may include at least one PTC heating element, and the PCM of the thermal reservoir heater may be contained in a vessel that is in contact with the PTC heating element.", "In accordance with another aspect of the present disclosure, an electrically-powered vehicle (EV) is disclosed.", "The EV may include a passenger

understanding of this disclosure or which render other details difficult to perceive may have been omitted.", "It should be understood, of course, that this disclosure is not limited to the particular embodiments disclosed herein.", "DETAILED DESCRIPTION Referring now to the drawings, and with specific reference to FIG.", "1, an electrically-powered vehicle (EV) 10 constructed in accordance with the present disclosure is shown.", "The EV 10 may be various types of electrically-powered vehicles such as battery electric vehicles (BEVs), plug-in hybrid electric vehicles (PHEVs), and hybrid electrical vehicles (HEVs) that are not plugged in.", "For example, if the EV is a BEV, it may include wheels 12, a passenger cabin 14, one or more batteries 16 that may be charged and at an external electrical power source such as an electric outlet 18, and an electric motor 20 that may be electrically connected to and powered by the battery 16.The electric motor 20 may be configured to drive a gearbox and the wheels 12 via various drivetrains 22.Furthermore, the EV 10 may include a regenerative braking system 23 that may return wasted energy from the wheels 12 to regenerate the battery 16, such as when the EV 10 is freewheeling downhill or braking.", "The EV 10 may operate in charging mode during which the electric motor 20 is off and the battery 16 is charging at the outlet 18, and in driving mode during which the vehicle is operational and is not connected to the outlet 18.The EV 10 may further include a heating, ventilation, and air-conditioning (HVAC) system 24 and an electronic control unit (ECU) 26 that may control the HVAC system 24 as well as various additional functions of the EV 10.The HVAC system 24 may be powered by the battery 16 and may be configured to control the temperature of the passenger cabin 14.As discussed in further detail below, the HVAC system 24 may include a thermal reservoir heater 29 (see FIG.", "3) that may store heat energy while the battery 16 of the EV 10 is charging at the electrical outlet 18, and may provide a heat source that does not place a power drain on the battery 16 while the EV 10 is in driving mode.", "If the EV 10 is a PHEV 30 it may include many of the above features and may further include an internal combustion engine (ICE) 32 and a fuel tank 34.The ICE 32 may combust fuel from the fuel tank 34 to drive the gearbox and the wheels 12 via various drivetrains 22.For example, the ICE 32 may drive the PHEV 30 while operating at high speeds, such as on freeways or open roads, and the electric motor 20 may drive the PHEV 30 on city streets.", "As is well-understood by those skilled in the art, a regenerative braking system 35 may return otherwise wasted energy from the wheels 12 to regenerate the battery 16, such as when PHEV 30 is freewheeling downhill or braking.", "In addition, the HVAC system 24 of the PHEV 30 may further include a coolant-based heating system 36 that may draw heat from the ICE 32 via one or more coolant lines 38 (see FIG.", "11 and further details below).", "Turning now to FIG.", "3, the HVAC system 24 of the EV 10 is shown in isolation.", "Except where indicated otherwise, the features of the HVAC system 24 as described below may be implemented in many types of EVs, including BEVs, HEVs, and PHEVs.", "FIG.", "3 depicts the HVAC system 24 while the EV 10 is in charging mode.", "The HVAC system 24 may include a blower 40, such as a fan 42, that may be configured to blow air from the passenger cabin 14 or outside of the vehicle into a conduit 44 that may carry the air to vents 46 leading to the passenger cabin 14 (at feet level, face level, windshield level, waist level, body level, etc.).", "Positioned in the conduit 44 downstream of the blower 40 may be a heating system 48 that may include an electric heater or heating zone 50 as well as the thermal reservoir heater or zone 29.In one implementation, the electric heater 50 and the thermal reservoir heater 29 may be separate heaters that are independently operated.", "In an alternative arrangement, the electric heater 50 and the thermal reservoir heater 29 may be separate zones 50 and 29 of a single heater that are independently operated of each other.", "Thus, although referred to as heaters 50 and 29 in the following paragraphs, it will be understood that the heaters 50 and 29 may be separate zones of a single heater as well.", "The electric heater 50 and the thermal reservoir heater 29 may each be configured to heat the air in the conduit 44 prior to delivery to the passenger cabin 14, and may be regulated independently of each other.", "The electric heater 50 may be powered by the battery 16 and may thus drain power from the battery 16 while the EV is in driving mode.", "In contrast, the thermal reservoir heater 29 may store heat while the battery 16 is charging at the outlet 18, and may use the stored heat to heat the passenger cabin 14 without draining the battery 16 while the EV is in driving mode.", "The electric heater 50 and the thermal reservoir heater 29 may be separated by a barrier 52, and an airflow regulating device 54, such as a blend door 56, that may be upstream or downstream of the electric heater 50 and the thermal reservoir heater 29 to regulate the flow of the air to or from the electric heater 50 and/or the thermal reservoir heater 29.For example, the airflow regulating device 54 may adopt a first position 58 in which all or some of the air from the blower 40 is sent to the electric heater 50, a second position 60 in which all or some of the air from the blower 40 is sent to the thermal reservoir heater 29 (see FIG.", "9), as well as various intermediate positions therebetween in which different fractions of the air are passed to the electric heater 50 and the thermal reservoir heater 29.As explained in further detail below, the airflow regulating device 54 may be controlled by the ECU 26 (see FIG.", "12).", "FIGS.", "4-7 depict an exemplary construction of the heating system 48 of the HVAC system 24.The air to be heated by the heating system 48 may be passed through fins 61, and the electric heater 50 may be disposed on one side of the thermal reservoir heater 29 and separated therefrom by the barrier 52, such as in the arrangements shown in FIGS.", "4-5.If the heating system 48 is arranged as in FIG.", "5, it will be understood that it may also include the details shown in FIG.", "4 as well.", "In one aspect of the present disclosure, the electric heater 50 may be a positive temperature coefficient (PTC) heater 62 which may include a number of PTC units 64 or stones that include barium titanate or another suitable material.", "The PTC heating units 64 may be oriented parallel to one another with gaps 66 therebetween to permit the passage of air between the PTC heating units, although many alternate configurations of the PTC heating units 64 are possible.", "The use of the PTC heater 62 as the electric heater 50 may be advantageous over other types of electric heaters, such as resistive heaters, as the PTC heater 62 may be incapable of overheating.", "However, the electric heater 50 may be another type of electric heater as well, such as a resistive heater, a thin film heater, among other types of heaters.", "Referring still to FIGS.", "4-7, the thermal reservoir heater 29 may include a second heater 68, such as an electric heater, as well as a thermal storage component 70 in heat-exchange relation with the second heater 68 such that the thermal storage component 70 may collect heat from the second heater 68 while the EV 10 is in charging mode.", "The second heater 68 may be powered/heated by the battery 16 while the EV 10 is in charging mode, and the heat from the second heater 68 may be transferred to the thermal storage component 70 to store heat in the thermal storage component 70.As one possibility, the second heater 68 may be a PTC heater 72 that includes one or more PTC units 73 or stones, such as barium titanate stones, that heat up while the battery 16 is charging at the outlet 18.Alternatively, the second heater 68 may be another type of electrically-powered heater, such as a resistive heater, a thin-film heater, among other types of heaters.", "In addition, in other alternative arrangements, the electric heater 50 and the second heater 68 may be separate units (50 and 68) integrated into a single heater that performs the functions of both of heaters.", "For example, a single heater may contain multiple zones or legs (such as PTC units 64 and 73) that are operated independently or in sets.", "In such an arrangement, the single heater may supply heat to the thermal storage component 70 during charging.", "As yet another possibility, several heaters may perform the functions of the heaters 50 and 68.As best shown in FIGS.", "6-7, the thermal storage component 70 may be in contact with each of the PTC units 73 to permit heat transfer from the PTC unit 73 to the thermal storage component 70 during charging of the EV 10.For example, the thermal storage component 70 may be contained in a vessel 74, such as a rectangular (FIG.", "6), round (FIG.", "7) or other shaped tube, that surrounds or is otherwise in thermal contact with the PTC unit 73 of the second heater 68.Alternatively, the thermal storage component 70 may be contained in a vessel or other structure inside of the PTC unit 73, or it may be arranged in a vessel alongside of the PTC unit 73.In one aspect of the present disclosure, the thermal storage component 70 may be a phase change material (PCM) 76 that may undergo a phase change at a characteristic phase change temperature with a concomitant absorbance or release of heat.", "As used herein, a PCM is a material that uses the latent heat of fusion to store or release energy when undergoing a change of phase.", "As one possibility, the PCM 76 may melt to a liquid (and absorb heat) and solidify to a solid (and release heat) at the phase change temperature, although other types of phase changes (e.g., solid-solid, gas-liquid, etc.)", "may also apply.", "For example, the second heater 68 may heat the PCM 76 while the EV 10 is in charging mode, causing the PCM 76 to melt to a liquid and absorb/store heat.", "When exposed to cold air flowing through the conduit 44, the PCM 76 of the thermal reservoir heater 29 may solidify with a concomitant release of heat that warms the air in the conduit 44.The PCM 76 may be any suitable type of PCM such as, but not limited to, a eutectic mixture, a salt hydrate, or organic material such as waxes, oils, fatty acids, and polyglycols.", "Non-limiting examples of PCMs that may be used as the thermal storage component 70 include pure salts (ionic compounds comprising, at least in part, a metal cation or other cation), and metals such as relatively low temperature metals that transition between solidus and liquidus in a lower temperature regime (<1000° C.) such as lead, lithium, silver, zinc, and aluminum.", "Other non-limiting examples of PCMs include hydrated salts, hydrated salts in solution, hydrated salts chemically modified to hinder segregation or other undesirable traits during operation, and organic PCMs such as polymers which may be compounds derived from plant or animal fats, such as paraffin, fatty acids, waxes, hydrogenated oils, and polyglycols, among others.", "In addition, the PCM 76 may have a phase change temperature compatible with the heating range of the second heater 68.For example, if the second heater 68 operates at temperatures of about 200° C. or below, the PCM 76 may have a phase change temperature of between about 50° C. to about 150° C. However, it will be understood that the thermal storage component 70 may be any other type of component capable of storing heat during battery charging for later release.", "Referring again to FIG.", "3, a process for storing heat to the thermal storage component 70/PCM 76 while the EV 10 is in charging mode will now be described.", "When the EV 10 is in charging mode, the second heater 68 may be powered by the battery 16 to provide heat to the thermal storage component 70/PCM 76.The second heater 68 may be heated to a temperature above the PCM 76 melting temperature, causing the PCM 76 to melt and absorb heat, or undergo another type of heat-absorbing phase change.", "Once the PCM 76 has fully or at least partially melted, the second heater 68 may be switched off to allow power from the electrical outlet 18 to be used for other purposes.", "In this arrangement, the energy flow may be from the electrical outlet 18 to the battery 16 (electrical energy) to the second heater 68 (electrical energy) to the thermal storage component 70/PCM 76 (heat energy), although there may be other energy flows used to transfer the energy to the second heater 68.The storage of heat to the thermal storage component 70/PCM 76 may occur automatically, or may be set manually.", "Turning to FIG.", "8, the electric heater 50 may pre-condition or pre-heat the passenger cabin 14 to a desired temperature (or temperature range) while the EV 10 is in charging mode.", "Specifically, the blower 40 may draw in air 78 to be heated from the passenger cabin 14 and/or from the outside environment.", "The airflow regulating device 54 may be in the first position 58 or another intermediate position to ensure that at least some of the air 78 is passed to the electric heater 50 and to prevent heat loss from the thermal storage component 70/PCM 76.Using power from the battery 16 while the EV 10 is in charging mode, the electric heater 50 may heat the air 78 to the desired temperature and the heated air 78 may then pass to the vents 46 for delivery into the passenger cabin 14.Pre-conditioning of the passenger cabin 14 in this way may reduce the power burden on the battery 16 caused by the electric heater 50 while the EV 10 is in driving mode, as significantly more energy may be required to heat up the passenger cabin 14 to a warm temperature from a cold temperature than is required to maintain the cabin 14 at the warm temperature.", "Pre-conditioning of the cabin 14 may occur automatically or may be requested by a user/driver at a user input control 80 (see FIG.", "12 and further details below), such as a control button in the passenger cabin 14, a computerized interface in the passenger cabin, or an internet enabled device such as a personal computer or mobile device.", "FIG.", "9 shows the HVAC system 24 while heating the passenger cabin 14 with the thermal reservoir heater 29.In the depicted arrangement, the thermal reservoir heater 29 is heating the air 78 while the EV 10 is in driving mode.", "The airflow regulating device 54 may be in the second position 60 or another intermediate position such that at least some of the air 78 drawn into the conduit 44 by the blower 40 is directed to the thermal reservoir heater 29.For example, the device 54 may be partially or fully open to direct at least some of the air 78 to the thermal reservoir heater 29.The passage of the air 78 by or through the thermal reservoir heater 29 may cause the thermal storage component/PCM 76 to undergo a phase change during which heat is released into the air 78 to heat up the air 78.Since the heat energy was stored in the thermal reservoir heater 29 during charging of the battery 16 as described above, the thermal reservoir heater 29 may heat the air 78 without imposing a power drain on the battery 16.This heating arrangement may be used, for example, to maintain the desired temperature in the passenger cabin 14 after the passenger cabin 14 has been pre-conditioned by the electric heater 50 as shown in FIG.", "8.As less energy is required to maintain the desired temperature than is required to heat up the passenger cabin 14 from an initial cold temperature, the thermal reservoir heater 29 may heat the air 78 for a relatively long period of time without draining power from the battery 16 and henceforth reducing the driving range of the EV 10.In addition, the electric heater 50 may be off at this stage so that it is not drawing power from the battery 16.It is noted that heating of the cabin 14 as described above may occur automatically or may be manually requested by the user using controls in the cabin 14.The thermal energy stored in the thermal reservoir heater 29 may be depleted when the PCM 76 has completed the heat-releasing phase change.", "At this point, and if passenger cabin heating is still needed while the EV 10 is in driving mode, the electric heater 50 may heat the air 78 as shown in FIG.", "10.Specifically, the airflow regulating device 54 may revert to the first position 58 or another intermediate position such that at least some of the air 78 drawn into the conduit 44 is directed to the electric heater 50.For example, the device 54 may be fully or partially closed to direct at least some of the air 78 to the electric heater 50.As the electric heater 50 may be powered by the battery 16, heating of the air 78 as shown in FIG.", "9 may drain power from the battery 16, possibly reducing the driving range of the EV 10.If the EV 10 is the PHEV 30, then heating of the passenger cabin 14 may be alternatively provided by the coolant-based heating system 36 after the thermal storage component 70 is depleted (see FIG.", "10).", "Although well understood by those with ordinary skill in the art, the general operation of the coolant-based heating system 36 will now be described.", "Specifically, a blower 82 of the coolant-based heating system 36 may draw air 78 to be heated into a conduit 84 configured to carry the air 78 from the blower 82 to vents 86 leading to the passenger cabin 14.The air 78 from the blower 82 may first be passed through an evaporator 88 in the conduit 84 which may at least partially dehumidify the air 78.An airflow regulating device 90, such as a blend door, may be downstream of the evaporator 88 in the conduit 84 and may direct the air 78 to a heat exchanger (HEX) 92 for heating.", "The HEX 92 may be in heat exchange relation with one or more coolant lines 38 which may carry heat from the ICE 32 (also see FIG.", "2).", "The HEX 92 may collect heat from the coolant line(s) 38 and may use the heat to heat the air 78 prior to entry into the passenger cabin 14.In some arrangements, the heating system 36 may also include an electric

accompanying drawings in the embodiments of the present disclosure.", "FIG.", "1 is a flowchart of a write method for a storage device according to an embodiment of the present disclosure.", "The write method shown in FIG.", "1 includes: 101.Acquire n numerical values that need to be written.", "102.Determine n bits corresponding to the n numerical values that need to be written, and information about a stuck-at fault included in the n bits, where the information about the stuck-at fault includes a location of the stuck-at fault in the n bits and a numerical value of a bit in which the stuck-at fault is located.", "103.Group the n bits into B groups of bits, so that the B groups of bits meet a grouping condition, and when the n bits represent a two-dimensional array of B rows and A columns, any two bits that belong to a same group in the n bits are in different rows and columns or any two bits that belong to a same group in the n bits are in a same row, where the grouping condition is used to limit a type or quantity of stuck-at faults included in each group of bits in the B groups of bits.", "104.Correspondingly write, to the n bits according to information

located, the n numerical values that need to be written, where n, A, and B are positive integers, and n≤A×B.", "In this embodiment of the present disclosure, it is determined, by adjusting an interval between two adjacent bits in a same group, that n bits are grouped into B groups, and numerical values that need to be written can be correspondingly written to the n bits according to information about a stuck-at fault in each group of the B groups, so that a write error caused by a stuck-at fault in an impedance storage device can be effectively prevented.", "In step 102, the n bits are locations to which the n numerical values in step 101 need to be correspondingly written.", "In addition, when the n bits are determined, the information about the stuck-at fault included in the n bits may also be determined.", "The information about the stuck-at fault may include a quantity of stuck-at faults included in the n bits, the location of the stuck-at fault in the n bits, and the numerical value of the bit in which the stuck-at fault is located.", "For ease of understanding, the n bits determined in step 102 may be numbered 1 to n, which may also be understood as location numbers of the n bits.", "In step 103, first, initial grouping is performed on the n bits.", "The initial grouping may be: each A bits in the n bits are successively grouped as one group, so that the n bits are grouped into the B groups of bits during the initial grouping, where each of the first B−1 groups of bits in the B groups of bits includes A bits, and the Bth group of bits, that is, the last group of bits, includes n−A×(B−1) bits.", "Optionally, in step 103, it may be understood that the n bits are grouped into the B groups of bits, so that when the n bits represent the two-dimensional array of B rows and A columns, a location, of the jth bit in the ith group of bits in the B groups of bits, in the two-dimensional array of B rows and A columns should meet: pi,j+1=pi,j+1 and qi,j+=(qi,j+k)mod B.", "In addition, a value of k may be adjusted, so that the B groups of bits meet the grouping condition, where pi,j is a column number, of the jth bit in the ith group of bits in the B groups of bits, in the two-dimensional array, qi,j is a row number, of the jth bit in the ith group of bits in the B groups of bits, in the two-dimensional array, i and qi,j are positive integers not greater than B, j and pi,j are positive integers not greater than A, k is a non-negative integer less than B, and the adjusting the value of k includes increasing the value of k by 1, where B is a minimum prime number not less than √{square root over (n)}, and A = ⌈ n B ⌉ .", "Furthermore, the n bits may be mutually corresponding to the two-dimensional array according to the initial grouping.", "For example, one row in the two-dimensional array may be corresponding to one group in the initial grouping, that is, k=0.Alternatively, if it is assumed that a location number of a bit in the n bits is x, and a corresponding row and column of the bit in the two-dimensional array are a and b, x=(b−1)×A+a should be met.", "It should be noted that k corresponding to initial groups may also be another integer less than B, such as 1, 2, or B−1, which is not limited in the present disclosure.", "Optionally, in step 103, it may also be understood that the n bits are grouped into the B groups of bits, so that a difference between location numbers, in the n bits, of two adjacent bits in each of the B groups of bits is k×A+1, or, that is, bits at intervals of k×A+1 in the n bits belong to a same group.", "Furthermore, if n=A×B, it may be considered that a next bit of the nth bit in the n bits is the first bit of the n bits, or it may be considered that the n bits are linked head-to-tail circularly and are grouped at intervals.", "If n≤A×B, it may be considered that the (n+1)th bit to the (A×B)th bit are empty, a next bit of the nth bit in the n bits is the empty (n+1)th bit, a next bit of the (A×B)th bit is the first bit in the n bits, or it may be considered that A×B bits are linked head-to-tail circularly and are grouped at intervals.", "Optionally, in step 103, it may also be understood that the n bits are grouped into the B groups of bits, so that when the n bits are corresponding to n data points in a two-dimensional Cartesian coordinate system, two data points corresponding to any two bits that belong to a same group have a same vertical coordinate in the two-dimensional Cartesian coordinate system, or two data points corresponding to any two bits that belong to a same group have different horizontal coordinates and vertical coordinates in the two-dimensional Cartesian coordinate system.", "In addition, multiple straight lines with a same slope may be made, and all data points in a same straight line belong to a same group.", "In addition, the slope of the multiple straight lines is k. Furthermore, for a correspondence between the n bits and the n data points in the two-dimensional Cartesian coordinate system, refer to a correspondence between the foregoing n bits and points in the two-dimensional array.", "For example, data points that have a same vertical coordinate and in the n data points in the two-dimensional Cartesian coordinate system may be corresponding to one group in the initial groups of the n bits, that is, the slope k=0.Optionally, k corresponding to the initial group may also be another integer of B−1 values, which is not limited in the embodiment of the present disclosure.", "It should be noted that the foregoing descriptions are grouping analyses performed only from different mathematics angles, where a common parameter is k. The parameter k may be understood that a location interval, in the n bits, between two adjacent bits in a same group is k×A+1.The parameter k may also be understood as a difference between rows in which two adjacent bits in a same group are located in a two-dimensional array.", "The parameter k may also be understood as a slope of a line in which bits in a same group are located in a two-dimensional Cartesian coordinate system.", "During further grouping adjustment, a new group may be determined by adjusting the value of k. Herein, the adjusting the value of k may be increasing the value of k by 1, for example, increasing from 0 to 1 or increasing from 1 to 2.A value range of k includes B integers from 0 to B−1.A person skilled in the art can understand that a manner that can be represented as determining groups using a value change of the parameter k still falls within the scope of this embodiment of the present disclosure even if another mathematics means or method is used to perform analysis.", "Optionally, as an embodiment, the grouping condition described in step 103 may be a first grouping condition: A quantity of stuck-at faults included in each group of bits in the B groups of bits does not exceed one.", "Optionally, as another embodiment, the grouping condition described in step 103 may be a second grouping condition: A type of the stuck-at fault included in each group of bits in the B groups of bits is the same, where the type of the stuck-at fault includes a stuck-at right fault and a stuck-at wrong fault;

10 denotes a generator, the reference numeral 12 denotes a steam turbine and 14 denotes a gas turbine.", "The reference numeral 16 denotes the heat recovery steam generator.", "The generator 10 is connected to the steam turbine 12 by a drive shaft 18 in common to the gas turbine 14.An air compressor 20 is coupled to the drive shaft 18.The air compressor 20 compresses air A sucked from the outside, and supplies a combustor 22 with the air A of high temperature and high pressure.", "In the combustor 22, the compressed air is mixed with fuel which is supplied from a fuel line 24 to burn up, so that combustion gas of high temperature and high pressure is supplied to the gas turbine 14.Due to the expansion of combustion gas, a turbine in the gas turbine 14 is driven in rotation, whereby the generator 10 is operated.", "Exhaust gas 25, discharged from the gas turbine 14, is led to the heat recovery steam generator 16 through an exhaust duct 26.As shown in FIG.", "1, inside a duct 27 in the heat recovery steam generator 16, four types of heat exchangers, i.e., a high-temperature superheater 28, a low-temperature superheater 30, an evaporator 32 and an economizer 34 are installed from upstream to downstream in order along the flow direction of the exhaust gas 25 discharged from the gas turbine 14.The evaporator 32 is provided with a steam drum 36.The economizer 34 heats up a boiler feed water by exhaust gas 25 and then supplies water to the steam drum 36.The steam drum 36 separates water from the saturated steam generated in the evaporator 32.Inside of the steam drum 36, a water level is maintained at a predetermined level, such that water and the saturated steam are well balanced.", "The evaporator 32 is recharged with water which is separated from the saturated steam in the steam drum 36.The saturated steam inside the steam drum 36 is transferred to the low-temperature superheater 30 through a saturated steam pipe 38.The saturated steam is superheated in the low-temperature superheater 30 and is then transferred to the high-temperature superheater 28.Steam is further superheated in the high-temperature superheater 28.A desuperheater 40 for regulating steam temperature is installed between the low-temperature superheater 30 and the high-temperature superheater 28.An outlet pipe 42 is connected to a outlet of the high-temperature superheater 28.The steam superheated by the high-temperature superheater 28 is transferred to the steam turbine 12 through the outlet pipe 42.The steam turbine 12 is rotated by the expansion of the superheated steam.", "The expanded steam is transferred to a condenser 43 to turn into water.", "Then, the water, passing through a condensate return pipe 45 by a condensate pump (not shown), is pressurized by a feed water pump 46.Thereafter, water is returned to the economizer 34.Fuel supply pipes 54 and 55, which respectively supply fuel to auxiliary burners 50 and 52, branch from the fuel line 24.In the heat recovery steam generator 16 in this embodiment, the auxiliary burners 50 and 52 are installed on the locations, as described below.", "The first stage auxiliary burner 50 is located on the most upstream position in the flow direction of the exhaust gas 25.In the case of the heat recovery steam generator 16 in this embodiment, the first stage auxiliary burner 50 is installed on the upstream side relative to the high-temperature superheater 28.In the first stage auxiliary burner 50, there are disposed a plurality of burners 51 so as to face toward the high-temperature superheater 28 on the downstream position.", "The first fuel supply pipe 54 is provided with a fuel regulating valve 56 and a fuel shut off valve 57.Thus, the fuel regulating valve 56 controls the quantity of fuel to be burned in the burners 51 by regulating a valve opening of the fuel regulating valve 56.To cease the operation of the burners 51, the fuel shut off valve 57 is closed.", "The second stage auxiliary burner 52 is located on the downstream side of the first stage auxiliary burner 50.In the case of this embodiment, the second stage auxiliary burner 52 is located on the upstream side of the evaporator 32.In the second stage auxiliary burner 52, there are disposed a plurality of burners 53 so as to face toward the evaporator 32 which is located on the position downstream thereof.", "The second fuel supply pipe 55 is provided with a fuel regulating valve 58 that regulates the quantity of fuel, and a fuel shut off valve 59 that is closed when the operation of the burners 53 are suspended.", "In FIG.", "2, the reference numeral 60 denotes a control unit that controls the operation of ignition and extinction of the first and second auxiliary burners 50, 52 and a flow rate of fuel to be charged to the first and second auxiliary burners 50, 52.The flow rate of fuel flowing through the fuel line 24 is detected by a flowmeter 62 and is inputted to the control unit 60.As shown in FIG.", "3, a distribution ratio of the charging quantity of fuel to the first stage auxiliary burner 50 and second stage auxiliary burner 52 is predetermined.", "Based on the fuel distribution ratio relationship, the control unit 60 is configured to regulate the opening of the fuel regulating valves 56 and 58 respectively, so as to control the fuel flow rate to the first stage auxiliary burner 50 and the second stage auxiliary burner 52.The heat recovery steam generator in this embodiment is as structured above.", "Next, the operation and the effect thereof will be described hereafter.", "At first, the operation of the first stage auxiliary burner 50 and the operation of the second stage auxiliary burner 52 are described.", "The second stage auxiliary burner 52 is installed on the upstream side of the evaporator 32.Thus, when the exhaust gas 25 is heated by flames spurted from the burners 53, as a whole, evaporation amount in the evaporator 32 can be increased.", "In contrast, the first stage auxiliary burner 50 is installed on the upstream side of the high-temperature superheater 28 and the low-temperature superheater 30.Thus, when the exhaust gas 25 is heated by flames spurted from the burners 51, a degree of superheating of steam generated in the high-temperature super heater 28 and the low-temperature superheater 30 can be increased.", "Process of controlling the fuel distribution to the first stage auxiliary burner 50 and the second stage auxiliary burner 52 will be described with reference to FIG.", "3.In FIG.", "3, the abscissa of the graph shows the sum total of charging quantity of fuel to the first stage auxiliary burner 50 and the second stage auxiliary burner 52, and the ordinate of the graph shows the charging quantity of fuel to each of auxiliary burner 50 and 52.The polygonal line A shows a variation in the charging quantity of fuel to the first stage auxiliary burner 50, and the polygonal line B shows a variation in the charging quantity of fuel to the second stage auxiliary burner 52.Since the abscissa is the sum total of charging quantity of fuel, the sum of gradient values of the line A and the line B equals to 1.In proportion to increase in the charging quantity of fuel, fuel is distributed between the first stage auxiliary burner 50 and the second stage auxiliary burner 52, in the manner as described below.", "In FIG.", "3, in this embodiment, the distribution pattern is divided into three regions, i.e., a small charging quantity region, a intermediate charging quantity region and a large charging quantity region, where fuel charging quantity differ from one another in distribution pattern.", "Firstly, while the heat recovery steam generator 16 is operated without setting fire to the auxiliary burners 50 and 52, it happens that the quantity of steam in the steam turbine 12 comes short.", "In this case, in order to increase the quantity of steam to be supplied to the steam turbine 12, the burners 53 in the second stage auxiliary burner 52 are set fire and the charging quantity of fuel thereto is increased (line segment b1).", "In a case where both of the second stage auxiliary burner 52 and the first stage auxiliary burner 50 are fired from the beginning and the charging quantity of fuel thereto are simultaneously increased, or the first stage auxiliary burner 50 is fired prior to the ignition of the second stage auxiliary burner 52 and the charging quantity of fuel thereto is increased, the high-temperature superheater 28 and the low-temperature superheater 30 may be excessively superheated by exhaust gas of high temperature, in spite of a insufficient quantity of steam.", "The temperature of steam at the generator outlet is controlled by the desuperheater 40 provided between the high-temperature superheater 28 and the low-temperature superheater 30.When steam is excessively superheated, a spray flow rate in the desuperheater 40 may become superfluous and/or water induction to the low-temperature superheater 30 and the high-temperature superheater 28 may have some trouble.", "Taking these drawbacks into consideration, setting fire on the second stage auxiliary burner 52 and the feeding of fuel thereto are started precedently, and the first stage auxiliary burner 50 is suspended in the small charging quantity region.", "As shown by the line segment b1 in FIG.", "3, in the small charging quantity region, the control unit 60 linearly increases the charging quantity of fuel to the second stage auxiliary burner 52 at a constant rate, upon a request of increase in steam flow rate.", "Since the firepower of the burners 53 increases in accordance with increasing in the charging quantity of fuel, quantity of steam in the evaporator 32 increases by means of the exhaust gas 25 heated by the burners 53.Steam from the evaporator 32 is fed to the low-temperature superheater 30, the high-temperature superheater 28 in order.", "In the superheaters 30 and 28, steam is superheated by the exhaust gas 25 discharged from the gas turbine 14.Then, the superheated seam is supplied to the steam turbine 12.At this moment, since the first stage auxiliary burner 50 is suspended, there is no possibility that steam is excessively superheated in the high-temperature superheater 28 and the low-temperature superheater 30.And superfluous spraying in the desuperheater 40 that controls steam temperature can be prevented.", "Thus, the steam temperature can be appropriately controlled.", "In the heat recovery steam generator 16 in this operating stage, increase in the amount of steam to be supplied to the steam turbine 12 is not so large.", "While the first stage auxiliary burner 50 is suspended, the second stage auxiliary burner 52 can afford the amount of steam required by the steam turbine 12.As shown in FIG.", "3, when the charging quantity of fuel to the second stage auxiliary burner 52 has reached a predetermined quantity, a fuel distribution control in the intermediate charging quantity region starts succeedingly.", "In the intermediate charging quantity region, the first stage auxiliary burner 50 is set fire, in addition to the second stage auxiliary burner 52.After the burners 51 have been fired, the charging quantity reaches a quantity necessary for producing pilot flames.", "After that, the charging quantity of fuel is maintained constant (line segment a1).", "Simultaneously, while the charging quantity of fuel to the first stage auxiliary burner 50 increases, the second stage auxiliary burner 52 is charged with fuel at a constant flow rate.", "For the purpose of increasing the amount of steam to be supplied to the steam turbine 12, the control unit 60 linearly increases the charging quantity of fuel to the second stage auxiliary burner 52 at a constant rate (line segment b2).", "Meanwhile, in the first stage auxiliary burner 50, the burners 51 are continuously burning in the manner to produce pilot flames.", "In the heat recovery steam generator 16 in this operating stage, the amount of steam evaporated in the evaporator 32 increases.", "However, without reheating by the first stage auxiliary burner 50, the high-temperature superheater 28 and the low-temperature superheater 30 can sufficiently superheat steam by the exhaust gas 25.Depending on an operating condition of the power plant, there is a possibility that the steam temperature at the generator outlet goes down.", "If it is necessary to raise the degree of superheating of steam, by means of the pilot flames of the burners 51 in the first stage auxiliary burner 50, it is possible to promptly cope with the situation where the degree of superheating of steam should be raised.", "As shown in FIG.", "3, when the charging quantity of fuel to the second stage auxiliary burner 52 has reached a predetermined quantity, control unit 60 succeedingly starts fuel distribution control in the large charging quantity region.", "In the large charging quantity region, for the purpose of increasing the amount of steam to be supplied to the steam turbine 12, the control unit 60 increases the charging quantity at a constant rate, to both of the first stage auxiliary burner 50 and the second stage auxiliary burner 52.As shown by the line segment b3 in FIG.", "3, due to the increase in the charging quantity of fuel to the second stage auxiliary burner 52, the amount of steam generated in the evaporator 32 increases.", "In this case, unless the exhaust gas 25 is heated by the first stage auxiliary burner 50 in order to raise the temperature of the exhaust gas 25, steam is insufficiently superheated in the high-temperature superheater 28 and the low-temperature superheater 30, whereby the steam temperature at the generator outlet might decrease.", "Accordingly, in the case where the steam temperature goes down, the charging quantity on fuel is increased at a constant rate as shown by the line segment a2 to build up the firepower of the burners 51 and raise the temperature of exhaust gas 25, while monitoring the steam temperature at the generator outlet.", "Succesively, the degree of superheating of steam in the high-temperature superheater 28 and the low-temperature superheater 30 can be raised.", "According to the embodiment, in the sum amount of the charging quantity of fuel to the first stage auxiliary burner 50 and the second stage auxiliary burner 52, the increasing rate of charging quantity of fuel to the first stage auxiliary burner 50 is set larger than the increasing rate to the second stage auxiliary burner 52.Thus, there is no possibility that the rise in the degree of superheating of steam cannot catch up with the increase in the amount of steam generated, whereby the relationship between the amount of steam generated and the steam temperature at the generator outlet can be kept appropriately.", "In addition, in view of the power plant as a whole, even when the amount of steam generated decreases because of the decrease in output of the gas turbine 14, the sufficient amount of steam at adequate temperature can be smoothly supplied, while increasing the charging quantity of fuel to the first stage auxiliary burner 50 and the second stage auxiliary burner 52.Note that the increasing rates of the charging quantity of fuel (gradients of the line segment a2 and the line segment b3) to the first stage auxiliary burner 50 and the second stage auxiliary burner 52 are taken by way of example, and are not limited thereto.", "In addition, as the charging quantity of fuel to the first stage auxiliary burner 50 and the second stage auxiliary burner 52 are not independently controlled, but the total amount of fuel is distributed in accordance with a certain ratio.", "Thus, when the charging quantity of fuel to the first stage auxiliary burner 50 is determined, the charging quantity of fuel to the second stage auxiliary burner 52 is simultaneously controlled in a correlative manner where the appropriate relationship between the amount of steam produced and the steam temperature.", "In this manner, the controlling system of fuel distribution to the first stage auxiliary burner 50 and the second stage auxiliary burner 52 can be achieved by such a simple system.", "The heat recovery steam generator according to the present invention has been described above by referring to the suitable embodiment.", "However, the embodiment is nothing more than an example, and the scope of the present invention is not limited thereto.", "Not limited to a steam turbine, the heat recovery steam generator of the present invention can be applied to a plant that supplies steam to a distilling plant, for example."
