In conventional speaker identification methods based on mel-frequency cepstral coefficients (MFCCs), phase information is ignored. Recent studies have shown that phase information contains speaker dependent characteristics, and, pitch synchronous phase information is more suitable for speaker identification. In this paper, we verify the effectiveness of pitch synchronous phase information for speaker identification in noisy environments. Experiments were conducted using the JNAS (Japanese Newspaper Article Sentence) database. The pseudo pitch synchronized phase information based method achieved a relative speaker identification error reduction rate of 15.5% compared to the conventional phase information (that is pitch non-synchronized phase). By cutting frames with low power and combining phase information with MFCC, a furthermore improvement was obtained.

Key parameters and options for choosing a capacitor charging power supply
Quasi- constant-power capacitor charging power supplies cas study
Written by: Isaac Zuker, CTO, Advice Electronics Ltd.
Estimated reading time: 9 minutes
Capacitor charging power supplies are used for pulsed-power applications such as IPL or pulsed lasers for aesthetic medicine and for driving pulsed lasers intended for diverse medical or industrial applications, among many other application fields.
Key parameters for choosing a capacitor charging power supply
The most important parameters which will determine which capacitor charging power supply you will choose and eventually integrate into your product are:
Among many, the main electrical parameters for choosing a capacitor charger are the following:
Output power: measured in Joules/Sec (or Watts). It determines how quickly the capacitor will be charged to the required operating voltage.
Repetition rate: indicates how many times per minute or per second the capacitor can be charged. The higher the rate, the higher the average power the capacitor charging power supply delivers.
Output voltage rating: Indicates the voltage to which the load capacitor will be charged.
Input leakage current: a safety parameter indicating the leakage current to Earth. For instance, for most medical applications the leakage current should usually be 0.5mA or less, depending on the device class and required certification.
User interface, which usually includes as a minimum: Enable/Disable signal for activating the charging power supply, a "Vset" analog control signal for setting the capacitor voltage at the end of charge, an "End-of-Charge" signal, indicating the capacitor is fully charged, and an alarm signal, indicating a malfunction.
Common capacitor charging power supplies technology
The technology used in the capacitor charging power supply has an impact on all the above parameters, especially on its physical size, its reliability and price.
In this paper we will discuss the standard, widely used constant current capacitor charging approach, and we will compare it to Advice Electronics Ltd.'s approach, which allows for smaller size, more reliable and cost-effective quasi-constant-power (QCP) capacitor charging power supplies.
Standard constant current capacitor charging approach
In the range of 1 or 2 KJoule/Sec. and above, most capacitor charging power supplies in the market are built using a constant current capacitor charging approach.
A bit of theory: the voltage (in Volts) across a capacitor is equal to the charge delivered to it (in Coulombs) divided by the capacitor's capacitance (in Farads). The charge delivered to the capacitor is equal to the integral of the current along the charging period. In this case, since the current is constant, we get a linear voltage charging profile of the capacitor.
Since the power delivered to the load at any moment, in this case a capacitor, is proportional to the output voltage multiplied by the output current, and since the output current is constant and the capacitor voltage increases linearly with time (starting from zero), we conclude that the output power the charging power supply delivers is initially zero, increasing linearly along the charging process.
For instance, let's suppose we are willing to deliver an energy of 3,000 Joules per second using a constant current charging power supply. At the beginning of the charging process the voltage across the capacitor is zero and accordingly, the power delivered by the charging power supply to the capacitor is zero, then it increases linearly until the charging process is complete (i.e. the desired voltage across the capacitor has been reached).
Since the capacitor voltage increases linearly along the charging period, so does the output power delivered by a constant current capacitor charging power supply (blue line), as shown in figure 1.
The energy in Joules delivered to the capacitor is equal to the area below the blue line in figure 1 below (vertical axis in Watts, horizontal axis in mSec.).
Since we require an average energy of 3,000 Joules per second (orange line), and the charging power delivered by the power supply starts from zero and increases linearly, the final, peak charging power the power supply delivers is 6,000 Joules per second, or 6,000W, as shown in figure 1 below.
This approach is simple, and the power supply construction is straightforward, comprising a constant current control loop. However, this approach offers a poor utilization of the power components of the power supply (such as power semiconductors, power transformers and power chokes), because those must be designed for withstanding at least twice the power required by the application – resulting either in a less reliable or in a larger and more costly device - and worse, often resulting in a combination of both.
Quasi-Constant-Power (QCP) Capacitor Charging Power Supplies
The main assumption behind this approach is that if we could deliver constant power to the capacitor, then, we could deliver an average energy of 3,000 Joules per second by delivering 3,000W along the charging process. Since this is half of the peak power required in a standard constant current charging power supply, we would get a smaller size, more reliable and cost-effective capacitor charging power supply.
In order to do so, let's calculate how the capacitor voltage and current should behave during the charging period.
Charger output power:
From (IX) we learn that if we could charge a capacitor while delivering constant power, the voltage across it would grow proportionally to the square root of the elapsed time.
This is shown in figure 2 below, depicting a simulation of the voltage across a 1,200uF capacitor being charged to 500V at a constant power of 3,000Joul/S (or 3,000W). The vertical (voltage) axis is in Volts and the horizontal (time) axis is in mSec. The charging time obtained in the simulation is 50mSec, which is in line with the following calculated charging time obtained by dividing the energy stored in the capacitor by the power delivered to it:
From (X) we learn that if we could charge a capacitor with constant power, the current at the beginning of the charging process (at t=0) would be infinite, decreasing with time.
Figure 3 below shows the results of a simulation of the current delivered to the capacitor (in Amps) while being charged at constant power (horizontal axis in mSec.). At the first moment (first millisecond not depicted) the current is infinite, and it decreases steadily until the capacitor is fully charged. Once the capacitor is charged the current drops to zero (after 50mSec) and its voltage remains constant.
The practical solution for optimal utilization of the power hardware of the charging power supply would be to start charging the capacitor at maximum constant current until reaching the capacitor charger maximum output power, then keep charging the capacitor at constant power till the desired voltage across the capacitor is reached.
This process is depicted in figure 4 below, which shows the simulation results of the voltage across the capacitor when charged by a quasi-constant power (QCP) capacitor charging power supply (vertical axis in Volts, horizontal axis in mSec.). The simulation parameters are:
Capacitor value: 1,200uF
Voltage at end of charge: 500V
Charger current limit: 22A
Constant power delivered: 3,250W
During the first 7mS the charging current is limited to 22A showing a linear voltage increase, and then the charging power delivered to the capacitor remains constant (at 3,250W) until full charge is achieved (at 500V).
Figure 5 below shows the charging current delivered by the QCP capacitor charging power supply to the capacitor during the charging period (vertical axis in Amps, horizontal axis in mSec.). During the first 7mS the charging current is limited to 22A, decreasing during the charging process.
Figure 6 below shows how the output power increases linearly (during the constant current charging period) from zero to full power during the first 7mS until full power (3,250W) is achieved, then the output power remains constant till the capacitor voltage reaches the desired voltage (500V) – and then it drops to zero after 50mS of charging (vertical axis in Watts, horizontal axis in mSec.).
Figure 7 below shows an oscillogram of the voltage across the capacitor recorded during the charging period, obtained with a real QCP capacitor charging power supply (Advice Electronics, Model LCH-3000-500). The oscillogram in figure 7 was recorded with an oscilloscope Agilent DSO7014B.
The measured result shown in figure 7 (capacitor charged from zero to 500V in 50mS) compares very well with the theoretical, simulated charging curve shown in figure 4: they are almost identical with a minor deviation during the period between 8mS and 22mS, as can be seen in figure 8 below, in which the measured capacitor voltage (in yellow, as previously shown in figure 7) is properly scaled and superimposed upon the simulated quasi constant power (QCP) charging curve (in blue, as previously shown in figure 4).
Comparing the two approaches on a practical basis
In order to charge a 1,200uF capacitor to 500V in 50mS, a constant current capacitor charging power supply needs to deliver a peak power of 6KW (as shown in figure 1), while a QCP capacitor charging power supply needs to supply a peak power of 3.25KW for achieving the same result.
Form the above discussion we learn that a QCP capacitor charging power supply must deliver a peak power equal to only 108% of the average required output power. A constant current capacitor charging power supply must deliver a peak power equal to 200% of the average required output power, roughly twice the peak power required from a QCP capacitor charging power supply.
This factor has a significant impact on the capacitor charging power supply design, size, reliability and cost.
We conclude that an effective quasi-constant-power (QCP) capacitor charging power supply approach requires from its power components considerably reduced stress and smaller size, resulting also in reduced cost and increased reliability, while operating at a significantly lower peak power than a constant current unit.
This results in a smaller size, more reliable and cost-effective capacitor charging power supply, like the LCH-XXX capacitor charging power supplies series from Advice Electronics Ltd. (Link To Capacitor Chargers Products)

Choosing Between an RPC-Style (remote procedure call) and a Message-Style (document-style) Web Service.
RPC-style Web services are interface driven, which means that the business methods of the underlying stateless session EJB determine how the Web service works. When clients invoke the Web service, they send parameter values to the Web service, which executes the corresponding methods and sends back the return values. The relationship is synchronous, which means that the client waits for a response from the Web service before it continues with the remainder of its application. Create an RPC-style Web service if your application has the following characteristics:
Examples of RPC-style Web services include providing the current weather conditions in a particular location; returning the current price for a given stock; or checking the credit rating of a potential trading partner prior to the completion of a business transaction. In each case the information is returned immediately, implying a synchronous relationship between the client and the Web service.
RPC is essentially a Remote Procedure Call in which the client sends a SOAP request to execute an operation on the Web Service. The SOAP request contains the name of method to be executed and the parameter it takes. The server running the Web Service converts this request to appropriate objects (java method call, EJB method call etc with parameters of defined type), executes the operation and sends the response as SOAP message to client. At the client side, this response is used to form appropriate objects and return the required information (output) to the client. RPC-style Web Services are tightly coupled because the sending parameters and return values are as described in WSDL (Web Service Description Language ) file and are wrapped in the SOAP body. Following is an example SOAP Body of RPC-style Web Service, which invokes GetStockQuote method with input parameter "ORCL":
<SOAP-ENV:Envelope...> <SOAP-ENV:Body> <m:GetStockQuote xmlns:m="http://hello"> <m:Symbol>ORCL</m:Symbol> </m:GetStockQuote> </SOAP-ENV:Body> </SOAP-ENV:Envelope>RPC-style Web Services follow call/response semantics, and hence they are synchronous, which means that the client sends the request and waits for the response till the request is processed completely.
You should create a message-style (document-style) Web service if your application has the following characteristics:
Examples of message-style Web services include processing a purchase order; accepting a request for new DSL home service; or responding to a request for quote order from a customer. In each case, the client sends an entire document, such as purchase order, to the Web service and assumes that the Web service is processing it in some way, but the client does not require an answer right away or even at all. If your Web service will work in this asynchronous, document-driven manner, then you should consider designing it as a message-style Web service. NOTE: Document-Style web servives can use both one-way (non-blocking) calls and two-way (request-response) calls, but preferrable choice will be one-way calls.
Document-Style Web Service are loosely coupled and the request/response are in the form of XML documents. The client sends the parameter to the Web Service as XML document, instead of discrete set of parameter values. The Web Service processes the document, executes the operation and constructs & sends the response to the client as an XML document. There is no direct mapping between the server objects (parameters, method calls etc) and the values in XML documents. The application has to take care of mapping the XML data values. The SOAP Body of a Document-Style carries one or more XML documents, within its body. The protocol places no constraint on how that document needs to be structured, which is totally handled at the application level. Document-Style Web Service follows asynchronous processing. Following is an example SOAP body for Document-Style Web Service:
<SOAP-ENV:Envelope ...> <SOAP-ENV:Body> <StockQuoteRequest symbol="IBA-USA"/> </SOAP-ENV:Body> </SOAP-ENV:Envelope>The parameters of the methods which are to be exposed by the document style Web Service should be of type XML element only. The return type of the method can be either an XML element or void.
The Simple Object Access Protocol (SOAP) offers two messaging styles: RPC (Remote Procedure Call) and document style. One is for creating tightly coupled, inter-object style interfaces for Web services components; the other is for developing loosely coupled, application-to-application and system-to-system interfaces.
An RPC is a way for an application running in one execution thread on a system to call a procedure belonging to another application running in a different execution thread on the same or a different system. RPC interfaces are based on a request-response model where one program calls, or requests a service of, another across a tightly coupled interface. In Web services applications, one service acts as a client, requesting a service; the other as a server, responding to that request. RPC interfaces have two parts: the call-level interface seen by the two applications, and the underlying protocol for moving data from one application to the other. NOTE, it may be not only request-response (two-way) RPC call, but also one-way RPC call (but more often it is used with two-way calls).
The call-level interface to an RPC procedure looks just like any other method call in the programming language being used. It consists of a method name and a parameter list. The parameter list is made up of the variables passed to the called procedure and those returned as part of its response.
For Web services, SOAP defines the wiring between the calling and called procedures. At the SOAP level, the RPC interface appears as a series of highly structured XML messages moving between the client and the server where the Body of each SOAP message contains an XML representation of the call or return stack:
<env:Envelope xmlns:env="http://schemas.xmlsoap.org/soap/envelope/"> <env:Body> <sm:someMethod xmlns:sm="http://www.xyz.com/sm"> <someParams> <item>100</item> <item>200</item> </someParams> </sm:someMethod> </env:Body> </env:Envelope>
The transformation from call-level interface to XML and back occurs through the magic of two processes: marshaling and serialization.
The server goes through the reverse process to extract the information it needs. A listener service on the server deserializes the transport stream and calls a proxy stub on the server that unmarshals the parameters, decodes and binds them to internal variables and data structures, and invokes the called procedure. The listener process may be, for example, a J2EE servlet, JSP (JavaServer Page), or Microsoft ASP (Active Server Page). The client and server reverse roles and the inverse process occurs to return the server's response to the client.
The difference between RPC-Style and Document-Style is primarily in the control you have over the marshaling process. With RPC-style messaging, standards govern that process. With document-style messaging, you make the decisions: you convert data from internal variables into XML; you place the XML into the Body element of the encapsulating SOAP document; you determine the schema(s), if any, for validating the document's structure; and you determine the encoding scheme, if any, for interpreting data item values. The SOAP document simply becomes a wrapper containing whatever content you decide. For example, the SOAP document shown in following example contains an XML namespace reference, http://www.xyz.com/genealogy, that presumably includes all the information a receiving program needs for validating the message's structure and content, and for correctly interpreting data values:
<env:Envelope xmlns:env="http://schemas.xmlsoap.org/soap/envelope/"> <env:Body> <xyz:family xmlns:xyz="http://www.xyz.com/genealogy"> <parents> <father age="29">Mikalai</father> <mother age="29">Volha</mother> </parents> <children> ... </children> </xyz:family> </env:Body> </env:Envelope>
If you compare the steps involved in typical document-style message exchange process with those involved in processing an RPC-style message, you will notice they are essentially parallel processes:
The SOAP server reverses the process, potentially using a different XSLT, to validate, extract, and bind the information it needs from the XML document to its own internal variables. The roles reverse and the two follow inverse processes for returning and accessing any response values. The rules guiding the marshaling process are the primary difference between this process and that for RPC-style messages. With document-style, you as the SOAP client's author create those rules.
RPC-style messaging maps to the object-oriented, component-technology space. It is an alternative to other component technologies such as DCOM and CORBA where component models are built around programmable interfaces and languages such as Java and C#. RPC-style messaging's strength in this space lies in its platform independence. It offers a standards-based, platform-independent component technology, implemented over standard Internet protocols. One of the benefits of this style's XML layer is that clients and servers can use different programming languages, or technologies, to implement their respective side of the interface, which means one side can choose one set of technologies, such as J2EE's JAX-RPC, while the other chooses a completely different set, such as .NET's C#. RPC-style messaging's standards heritage can be an important consideration in hybrid environments (one using multiple technologies such as J2EE and .NET) and can provide a transition path between different technologies.
RPC-Style messaging's weaknesses
The coupling and synchronicity issues are common to RPC-based component technologies. So they are really not discriminators when making comparisons between these technologies. The marshaling and serialization overhead is greater for RPC-style messaging and places this messaging style at a relative disadvantage. However, with today's high-speed processors and networks, performance is generally not an issue.
Document-style messaging is clearly an option in any situation where an XML document is one of the interface parameters. It is ideal for passing complex business documents, such as invoices, receipts, customer orders, or shipping manifests. Document-style messaging uses an XML document and a stylesheet to specify the content and structure of the information exchanged across the interface, making it an obvious choice in situations where a document's workflow involves a series of services where each service processes a subset of the information within the document. Each service can use an XSLT to validate, extract, and transform only the elements it needs from the larger XML document; with the exception of those elements, the service is insensitive to changes in other parts of the document. The XSLT insulates the service from changes in the number, order, or type of data elements being exchanged. As long as the service creating the document maintains backwards compatibility, it can add or rearrange the elements it places into a document without affecting other services. Those services can simply ignore any additional data. Document-style messaging is also agnostic on the synchronicity of the interface; it works equally well for both synchronous and asynchronous interfaces.
Document-style messaging's weaknesses
There are two compelling reasons to use document-style messaging. One is to gain the independence it provides. Its strength lies in decoupling interfaces between services to the point that they can change completely independently of one another. The other is that document-style messaging puts the full power of XML for structuring and encoding information at your disposal. The latter is one reason many consider document-style superior to RPC-style messaging.
RPC-style messaging's strength is as a bridging component technology. It is a good option for creating new components and for creating interfaces between Web services and existing components - you simply wrap existing components with RPC-style Web services interfaces. RPC-style messaging is also an excellent component standard in situations where you are using multiple technologies, such as J2EE and .NET, and want to develop sharable components.
Document-style messaging's strengths are in situations where an XML document is part of the data being passed across the interface, where you want to leverage the full power of XML and XSL, and in instances where you want to minimize coupling between services forming an interface, such as in application-to-application and system-to-system interfaces.
WSDL Example for RPC-Style:
... <message name="myMethodRequest"> <part name="x" type="xsd:int"/> </message> <portType name="PT"> <operation name="myMethod"> <input message="myMethodRequest"/> </operation> </portType> ...NOTE: part element has attribute type.
RPC-Literal SOAP message for this request:
<soap:Envelope> <soap:Body> <myMethod> <x>5</x> </myMethod> </soap:Body> </soap:Envelope>
WSDL Example for Document-Style:
<types> <schema> <element name="xElement" type="xsd:int"/> </schema> </types> <message name="myMethodRequest"> <part name="x" element="xElement"/> </message> <portType name="PT"> <operation name="myMethod"> <input message="myMethodRequest"/> </operation> </portType>NOTE: part element has attribute element with value of globally declared element.
Document-Literal SOAP message:
<soap:Envelope> <soap:Body> <xElement>5</xElement> </soap:Body> </soap:Envelope>

Deputy Gorelkin announced a plan to speed up the Internet in Russia through new CDN servers
IN Russia intend to create national CDN servers (Content Delivery Network) to speed up the download of content on the Internet for residents of the country. This was stated by the deputy head of the committee State Duma for information policy, member “United Russia” Anton Gorelkinreports TASS.
CDN servers (Content Delivery Network) – a network of servers that services place in the networks of large Internet providers and at traffic exchange points in order to speed up the loading of website and application content.
“In connection with the sanctions, the processes of technical support for the server equipment of Western companies have stopped. Therefore, Russian companies have a favorable situation,” he said.
According to the deputy, the national CDN service “should not be another entity built for budget money.”
“Russian players in this market have enough capacity to compete with Google. We agreed that the model on the basis of which this interaction will be built will be formed by the Ministry of Digital Development,” Gorelkin added.

There are public phones available almost everywhere in Costa Rica.
They can be used to make calls anywhere in the world. These telephones function by using public telephone ICE cards. Buy them in 500, 1000, 5000 colones denominations at many authorized dealers – Universidad VERITAS book store, mini-markets, pharmacies, and liquor stores – that display the blue and yellow ICETEL sign.
Costa Rican phones operate similarly to those in the US. In all of Costa Rica, the area code (lada) is 506 and a number is usually written like this: 2246-4646. If you want to dial this number from the US, first dial “011” + 506 (area code) + number.
If you are bringing your smart phone from home, make sure to contact your phone company to confirm you will not have trouble putting a new SIM card into your phone. For example, iPhones will need to be "unlocked" prior to your arrival in Costa Rica. If you are bringing a non smart phone from home, make sure it is able to have the SIM card changed. If not, cell phones in Costa Rica are fairly inexpensive and can be purchased on campus or at the local malls.

Twelve Major Broadcast Groups to Form Joint Venture to Develop National Mobile Content Service
LAS VEGAS, NV – April 13, 2010 – Belo Corp., Cox Media Group, E.W. Scripps Co., Fox, Gannett Broadcasting, Hearst Television Inc., ION Television, Media General Inc., Meredith Corp., NBC, Post-Newsweek Stations Inc. and Raycom Media today announced plans to form a standalone joint venture to develop a new national mobile content service. Utilizing existing broadcast spectrum, the service will allow member companies to provide content to mobile devices, including live and on-demand video, local and national news from print and electronic sources, as well as sports and entertainment programming.
Broadcast spectrum to be utilized for the new mobile service will come from the three owned-and-operated station groups — Fox, NBC & Telemundo, and ION — and the nine local broadcast groups, which are Belo, Cox, E.W. Scripps, Gannett, Hearst, Media General, Meredith, Post Newsweek and Raycom. Separately, these nine local broadcast companies formed Pearl Mobile DTV Company LLC as a vehicle for their involvement in the venture.
By aggregating existing broadcast spectrum from its launch partners, the new venture will have the capacity to offer a breadth of mobile video and print content to nearly 150 million U.S. residents. In addition to broadcast spectrum, the partners will commit content, marketing resources and capital to the new venture. The service will employ ATSC-M/H, an open broadcast transmission system developed by the Advanced Television Systems Committee (ATSC) specifically for mobile devices.
The venture is designed to complement the Federal Communication Commission’s (FCC) National Broadband Initiative by giving consumers mobile access to video content while reducing congestion of the nation’s wireless broadband infrastructure. In addition, the service’s mobile content network will have the capacity to deliver local and national time-sensitive emergency information to citizens across the U.S.
Regarding the announcement, Jack Abernethy, Chief Executive Officer of Fox Television Stations, stated: “We are excited about building a platform that makes mobile television universally available and economically viable. This venture is the first step in forging cross-industry and company partnerships to deliver content to consumers.”
“This initiative offers a path for the next generation of video consumption, and will help the FCC in its goal of ensuring efficient and reliable broadband service for US consumers,” said John Wallace, President, NBC Local Media.
“Local broadcasters are the backbone of the U.S. media industry,” said David J. Barrett, President and CEO of Hearst Television Inc. “This sharing of content, broadcast spectrum, marketing resources and capital is unprecedented, and underscores U.S. broadcasters’ commitment to bringing vital local news, weather, and emergency information to increasingly mobile U.S. consumers. This is a critically important initiative that holds great promise for our audiences and the television industry. This is truly the next generation of local television service.”
“This venture takes to the next level the work we embarked upon three years ago with the development of Mobile DTV technology, in anticipation of digital TV capabilities and consumer mobile demand,” said Brandon Burgess, CEO of ION Television.
“Mobile digital television places each of our companies at the center of a consumer transformation, putting us on cell phones, netbooks, DVD players and even in-vehicle entertainment systems,” said David Lougee, President, Gannett Broadcasting, Gannett Co. Inc. “And it’s the consumers who are the big winners. From news and entertainment to emergency information, virtually all U.S. consumers will soon be able to bring their most valuable content with them wherever they go.”
Information regarding a dedicated management team that will focus on securing additional content, spectrum and distribution partnerships for the venture will be made available at a later date.

Remon Medical has developed a novel telemetry technology that enables a device implanted deep inside the body to communicate wirelessly with an external system, providing physicians with valuable tools to frequently monitor and treat several potentially life-threatening conditions in a non-invasive manner.
The Company’s core technology utilizes acoustic waves, which both energize and communicate with the implanted device. The advantage of this approach is that acoustic waves transmit effectively inside the body (through soft tissue, bones and fluids), and are not absorbed by the intervening tissue. Acoustic communication requires very little energy to achieve a high signal-to-noise ratio when accessing locations deep inside the body.
Remon’s proprietary technology is integrated into a minute implant, requiring no antenna, battery, or connecting leads. The system can either serve as a sensor, measuring parameters such as pressure, flow, temperature, and irradiation dosage, or as an activator for localized drug therapies and nerve or tissue stimulation. The implant contains an energy exchanger, a control chip, and a sensor or activator, all enclosed in a miniature casing, roughly the size of a grain of rice. The Remon solution also incorporates a specially developed external unit, capable of powering the implant and receiving information directly from the implanted sensor.
The main features of the Remon system include its:
Small size: The minute dimensions of the device are a key factor in enabling its implantation at locations deep inside the body, particularly if the implants are of a permanent nature. The small size may also allow the device to be seamlessly attached to other implants.
Wireless communication capability: The implants can be placed anywhere deep inside the body, without connecting leads or wires. Once the device has been implanted, the system’s wireless capabilities enable non-invasive monitoring and/or activation of therapeutic responses.
No need for battery, antenna: The implant is energized and activated on-demand via an external transducer. The implant converts the acoustic waves into electrical energy via its proprietary energy exchanger.
Omni-directional functionality: As the system’s internal transducer operates at a low resonance frequency, Remon’s implant is omni-directional, insensitive to the exact direction of the external transducer.
Safe and recognized technology: The system utilizes acoustic (ultrasound) communications, a proven and safe technology that healthcare professionals have been using for decades. As a result, the system can reach deep into the body without heating tissue.

As we move toward the end of our discussion of car audio electrical theory, we need to talk about capacitance and inductance and how the characteristics of those phenomena interact with AC and DC signals. There’s no doubt that these are advanced concepts, but even a basic understanding of how capacitors and inductors work is fundamental to a thorough understanding of mobile electronics systems.
What Is a Capacitor?
A capacitor is a two-terminal electronic component that stores energy. Capacitors are made of two metallic plates that are separated by an electrical insulator. When we apply a voltage to one terminal of the capacitor, the electrons on one plate will impose a force on the opposite plate to create an opposite charge. The result is that the plates have equal and opposite charges and thus, maintain an electric field. Because the plates in a capacitor are very close together, they can store a large amount of energy for their overall size.
Capacitors are quantified in units of farads. A farad is defined as one coulomb of charge on each plate, resulting in a voltage of one volt across the terminals.
Capacitors in DC Circuits
Capacitors are, at their most basic function, a device that stores a microscopic magnetic field between its plates. When we apply a DC voltage to a discharged capacitor, it appears as a short circuit for an instant as the magnetic and electric fields start to form between its plates. As the capacitor starts to store energy, it increases in effective resistance, and the amount of current flowing through the device is reduced. Once the capacitor has equalized with the supply voltage, almost no current passes through the device.
When we remove the supply voltage from a capacitor, it will attempt to maintain the voltage across the terminals. It is this characteristic that makes capacitors an ideal solution to reduce variations in voltage. Capacitors resist changes in voltage.
Inside the amplifiers in our car audio systems, capacitors are used to store large amounts of energy at the rail voltage. When there is a sudden demand for current that exceeds the capability of the power supply, the capacitors will release energy to maintain their initial voltage. This characteristic helps to stabilize the voltage of the amp during dynamic transients. This same concept applies to “stiffening capacitors” used on the 12V feed to your amplifier. When implemented using high-quality components, the addition of a large capacitor can help to provide transient current to the amp.
The Capacitor in AC circuits
In alternating current circuits, capacitors take on an interesting phenomenon of “virtual resistance.” As we know, capacitors don’t like to change voltage, yet an AC signal is one that is defined as ever-changing. Depending on the relationship between the capacitor value and the frequency of the AC signal, some amount of the current is allowed to pass through the cap.
If we attempt to measure the resistance of a capacitor with a conventional multimeter, we’ll find it shows an extremely high value. For AC signals, we use the formula Xc = 1 / (2 x 3.1416 x F x C) to calculate the effective resistance, where F is the frequency of the signal and the C is the value of the capacitor in farads. Because this resistance is not present in DC signals, we call it capacitive reactance.
If we wanted to create a simple filter circuit to limit the amount of low-frequency signal going to a speaker, we could wire a non-polarized capacitor in series with the speaker. To calculate the frequency at which the cap starts to reduce bass going to the speaker, we can rearrange the above equation to F = 1 / (2 x 3.1416 x R x C), where R is the same value as the speaker resistance. For a four-ohm speaker and a capacitor with a value of 200 uF (microfarads), we get a frequency of 198.9 Hz. At this frequency, the capacitor appears to have the same reactance as the speaker, and the signal that is going to the speaker is reduced by 50 percent. Because capacitance is inversely proportional to frequency, the impedance of the capacitor increases as frequency decreases. At 99 Hz, the reactance is 8 ohms, at 50 Hz, it’s 16 ohms, and so on. This phenomenon simultaneously reduces the current supplied by the amplifier and acts as a voltage divider between the cap and the speaker.
A capacitor in series with a speaker is known as a first-order high-pass filter. It reduces the output of the speaker at a rate of -6dB per octave as you move away from the crossover frequency as defined above. Capacitors are suitable as filters for midrange and high-frequency drivers in passive designs and as protection devices for tweeters in active designs.
What Is an Inductor?
In the simplest of terms, an inductor is a coil of wire that creates a magnetic field based on the amount of current flowing through it. Many inductors feature iron cores to increase the intensity of the magnetic field. Where a capacitor resists changes in voltage, an inductor resists changes in current flow. We know from our previous article on magnetism that current flowing through a conductor creates a magnetic field around that conductor. If we wrap the conductor in a loop, the proximity of the loops to one another intensifies the magnetic field.
Also from our previous article, we also know that a magnetic field can impose a voltage on a conductor. If the current in an inductor tries to change, the magnetic field attempts to create a voltage across the device to maintain the current flow.
A good analogy for an inductor is a flywheel on a motor. Once you have established a specific rotational speed, it takes a large amount of work to increase or decrease its speed. Inductors work the same way with current. They resist changes in current flow. Inductors are rated using the unit henry (H). A henry is defined as the opposition to electrical current flow through a device that results in one volt of electromotive force to appear across the terminals.
Inductors in Electrical Circuits
In most applications, we don’t want inductors in a 12V DC circuit because they resist changes in current flow. For a variable load such as an amplifier, a large amount of inductance in the supply wiring would result in an unstable supply voltage as the current requirements change.
There are some cases where inductors are used in combination with a capacitor to act as a noise filter.
In an AC circuit, inductors allow low-frequency signals to pass through the device with little to no effect. If we wire an inductor in series with a speaker, it acts as a high-pass filter. Unlike a capacitor, in a DC circuit, an inductor appears as a short circuit with very little resistance. To an AC signal, we can calculate the reactive inductance of a capacitor using the equation Xl = 1 x 3.1416 x F x L, where F is frequency and L is inductance in henries.
If we want to use an inductor as a high-pass filter, we can determine the effective crossover point by swapping the Xl for the resistance of the speaker. In this example, we’ll use an inductor with a value of 6 mH (millihenries) and a speaker with a nominal impedance of 4 ohms. There, the -3dB point of the filter circuit would be F = 4 / (2 x 3.1416 x 0.006), or 106.1 Hz. This value of inductor would make a good low-pass filter for a woofer. Just as with a capacitor in series with a speaker, an inductor acts as a first-order filter and reduces output at a rate of -12dB per octave as frequency increases from the crossover point.
Other Cases of Inductance and Capacitance
Anytime two conductors are parallel to each other and in close proximity, there will some level of capacitance. Many overly exuberant enthusiasts talk about capacitance in interconnect cables. While this is a factor, the microscopic changes (if indeed any are perceptible) can be compensated for during the tuning process of the system. When it comes to buying high-quality interconnects, noise rejection and overall design durability should be your top goals.
The voice coil winding in the speakers we use has a certain amount of inductance. This characteristic reduces high-frequency output by reducing current flow at high frequencies. Because speakers are dynamic, their parameters change as the speaker cone moves. In the same way that having an iron core in an inductor increases inductance as compared to an air-core design, the inductance of a speaker voice coil increases when the cone assembly moves rearward into the basket. The T-yoke in the center of the speaker increases the strength of the magnetic field created by the current in the voice coil. Likewise, as the speaker moves forward, the inductance decreases. These position-based inductance distortions can cause a high-frequency warbling effect that can be detrimental to the reproduction of your music. One solution is to implement an under-hung voice coil design where the gap is taller than the coil winding. The drawback to this design is that the voice coil is often small and lacks power handling. Another option is to include a copper pole piece cap to reduce the magnetic field and minimize distortion. A copper cap is an expensive option but offers excellent performance benefits.

No technology that is connected to internet is un-hackable. It's only a matter of time.
What is the OSI Model? The OSI, short for (the Open Systems Interconnection model) is a conceptual framework for understanding how network communication works. It was the first standard model adopted by all major computer and telecommunication companies in the early 1980s.
The OSI Model (aka ISO-OSI, i.e., International Organization of Standardization – Open System Interconnection) divides the communication process between two devices into seven layers. It provides a standard reference model that allows different networking technologies and protocols to interoperate and communicate.
Imagine you have two servers that need to share information. The message doesn't just magically teleport from an application on the first machine to the application on the other. Instead, it transits down the layers and eventually reaches the transmission line. Once it jumps across the gap to the other device, it has to repeat the process in reverse by ascending layers until it reaches the receiving application.
For any starting number N representing a layer that transmits a message, the OSI model can be used to explain the transmission few key concepts:
Protocol Data Units (PDUs) are abstracted messages that include payloads, headers, and footers.
Service Data Units (SDUs) are equivalent to the payloads.
At each subsequent transition from some layer N to some layer N-1, a layer-N PDU becomes a new N-1 SDU. This payload gets wrapped up in a layer N-1 PDU with the relevant headers and footers. On the opposite end, the data passes up the chain, unwrapping at each relevant stage until it's just a payload that the corresponding layer-N device can consume.
The 7 Layers of OSI
We'll describe OSI layers "top-down" from the application layer that directly serves the end user to the physical layer.
7. The Application Layer
The application layer is the highest layer of the OSI Model and is responsible for providing the interface between the network and the end user's application.
Standard network services such as file transfer, email, and web browsing are provided at the application layer. Protocols such as HTTPS (Hypertext Transfer Protocol Secure) and, FTP (File Transfer Protocol), SMTP (Simple Mail Transfer Protocol) operate at this layer, allowing users to access and transfer files and other resources over the network.
The application layer also provides the interface for user authentication and authorization. Protocols such as LDAP (Lightweight Directory Access Protocol) and Kerberos are used to verify the identity of users and grant them access to specific resources or services on the network.
6. The Presentation Layer
The presentation layer is responsible for formatting and encoding data in a standardized way independent of the application or system being used. It includes protocols like SSL (Secure Sockets Layer) that provide secure communication.
It deals with issues such as data compression and encryption.
An example of a presentation service would be converting an extended binary-coded decimal interchange code text computer file to an ASCII-coded file. The presentation layer could translate between multiple data formats using a standard format if necessary.
5. The Session Layer
The session layer establishes, maintains, and terminates connections between devices. Some standard protocols that operate at the session layer include Remote Procedure Call (RPC), NetBIOS (Network Basic Input Output System), and Windows Internet Name Service (WINS).
Some standard functions of the session layer include :
Setting up and tearing down communication sessions between devices.
Synchronizing the flow of data between devices.
Resuming communication after a temporary interruption or fault.
Negotiating the options and parameters for a communication session.
Managing access to shared resources during a communication session.
4. The Transport Layer
The transport layer provides end-to-end communication services and error recovery for the application layer. It includes protocols like TCP (Transmission Control Protocol) and (UDP) User Datagram Protocol that provides error correction, flow control, and data segmentation and reassembly.
Every protocol uses a unique decimal number to ensure that the data is sent and received on the intended application as it passes through the network or Internet.
TCP is a connection-oriented protocol that guarantees the delivery of the message, while UDP is a connectionless protocol that sends the data without error correction. Under the TCP and UDP are port numbers used to distinguish the specific type of application.
3. The Network Layer
The network layer is responsible for routing data between different networks. It includes protocols like (IP) Internet Protocol, (IPX) Internetwork Packet Exchange, and AppleTalk. These protocols provide the necessary functions for routing data across a network and ensuring it reaches its destination.
It is responsible for determining the best path for data as it travels from its source to its destination. The network layer also assigns logical addresses to devices on the network, which are used to identify the devices and route data to them.
The network layer is often considered the "heart" of the OSI model because it plays a central role in the operation of a network. It is a critical component of modern computer networks and is essential for allowing devices to communicate with each other and exchange information.
2. The Data Link Layer
The data link layer links two devices on the same physical network, such as a local area network (LAN). It ensures that data is transmitted correctly and without errors.
It includes protocols like (SDLC) Synchronous Data Link Protocol, (HDLC) High-Level Data Link Protocol, (SLIP)Serial Line Interface Protocol, (PPP)Point - to - Point Protocol, (LCP) Link Control Protocol, and (NCP) Network Control Protocol.
This layer comprises two parts—Logical Link Control (LLC), which identifies network protocols, performs error checking, and synchronizes frames. Media Access Control (MAC) uses MAC addresses to connect devices and define permissions to transmit and receive data.
Overall, the data link layer is crucial in ensuring data's reliable and efficient transmission over a network.
1. The Physical Layer
The physical layer is responsible for transmitting raw data over a communication channel, including the hardware, cables, and other components that make up the network.
It defines the physical characteristics of the communication channel, including the signaling used, the frequency range, and the data rate.
The physical layer ensures that data is transmitted accurately and reliably from one device to another.

In collaboration with Intel and Accenture, 3DP4ME is using 3D printing to bring assistive technology to people in developing countries. 3DP4ME, an Intel RISE Technology Initiative partner, is currently piloting its project in Jordan, taking scans of children’s ears and printing custom-fitted hearing aids for them. The application of 3D printing increases access to hearing aids because it is faster and less expensive than traditional manufacturing methods.
“Previous work to provide hearing aids to children included hand-making the custom ear molds. It was a craft that was labor-intensive, and you could only make four or five hearing aids a day,” says Jason Szolomayer, founder of 3DP4ME. “There were long wait times, even after the kids were tested. Using 3D printing allows us to scale up the service we provide to families and kids who need hearing aids.”

In today's increasingly digital world, law firms rely on a stable and high-speed internet connection to access resources, communicate with clients, and manage daily operations. Understanding how internet connection bandwidth works and its impact on the user experience is essential for law firms of all sizes. In this blog post, we will explain the concept of internet bandwidth, how increasing users and applications affect it, and methods to manage bandwidth effectively. We will also discuss the optimal bandwidth for different sizes of law firms and the up/down speed variances of cable and fiber connections.
What is Internet Connection Bandwidth?
Internet connection bandwidth refers to the maximum amount of data that can be transferred over a network connection in a given period. It is typically measured in megabits per second (Mbps) or gigabits per second (Gbps). A higher bandwidth allows for faster data transfer rates, resulting in a smoother and more responsive online experience.
Impact of Increasing Users and Applications on Bandwidth
As the number of users and applications within a law firm increases, so does the demand for bandwidth. When multiple users access the internet simultaneously or when bandwidth-intensive applications are in use, the available bandwidth may become insufficient, resulting in slower connection speeds, buffering, and lag.
Some common applications used by law firms that can impact bandwidth include:
Cloud-based practice management software
Video conferencing tools like Zoom and Microsoft Teams
Voice over IP (VoIP) phone systems
Large file transfers and backups
Remote desktop solutions
Methods to Manage Bandwidth
To ensure a consistent and reliable internet connection, law firms should consider implementing the following strategies to manage bandwidth effectively:
Assess Bandwidth Needs
Regularly evaluate the firm's internet usage patterns and bandwidth requirements. This may involve monitoring network usage during peak hours, identifying high-bandwidth applications, and estimating the number of simultaneous users.
Upgrade the Internet Connection
If the current bandwidth is insufficient to meet the law firm's needs, consider upgrading to a higher-speed plan or switching to a fiber-optic connection, which offers faster speeds and greater reliability.
Implement Bandwidth Management Tools
Use Quality of Service (QoS) settings on the network router to prioritize critical applications and allocate a specific amount of bandwidth to each application. This can help ensure that essential services receive adequate bandwidth even during periods of high network usage.
Optimize Applications and Network Settings
Update software and applications regularly to ensure optimal performance. Additionally, configure network settings to minimize unnecessary data transfers and reduce bandwidth consumption.
Optimal Bandwidth for Different Sizes of Law Firms
The ideal bandwidth for a law firm depends on its size, the number of users, and the applications being used. As a general guideline:
Small law firms (1-10 users): A minimum of 50-100 Mbps should suffice for basic internet usage, email, and low-resolution video conferencing.
Medium-sized law firms (11-50 users): A bandwidth of 100-300 Mbps is recommended to accommodate moderate use of cloud-based applications, file transfers, and high-definition video conferencing.
Large law firms (50+ users): A bandwidth of 100 Mbps or higher is necessary for firms with extensive online activity, multiple simultaneous users, and a strong reliance on cloud-based services and applications. If you are adding VOIP services, it is recommended that you exceed 300+ Mbps.
Up/Down Speed Variances of Cable and Fiber
Cable and fiber internet connections differ in their upload and download speed capabilities:
Cable connections typically offer asymmetric speeds, meaning that download speeds are significantly faster than upload speeds. While this may be suitable for basic internet usage, it can be a drawback for applications that require high upload speeds, such as video conferencing and large file transfers. Cable internet speeds can range from 25 Mbps to 1 Gbps for downloads, while upload speeds are usually between 5 Mbps and 50 Mbps.
Fiber-optic connections, on the other hand, often provide symmetric speeds, offering equal upload and download capabilities. This makes fiber a more attractive option for law firms that rely heavily on cloud-based applications, video conferencing, and other bandwidth-intensive activities. Fiber connections can deliver gigabit speeds (1,000 Mbps or higher) for both uploads and downloads, ensuring a smoother and more consistent online experience.
In addition to the standard fiber-optic internet connections, there is another option available for organizations that require more robust connectivity: dedicated fiber. This service offers unique advantages that can greatly benefit law firms with high bandwidth needs and strict reliability requirements. In this section, we will discuss how dedicated fiber works and its benefits for law firms.
How Dedicated Fiber Works
Dedicated fiber, also known as a dedicated internet access (DIA) or dedicated fiber-optic line, is a type of internet connection that provides a private, dedicated fiber-optic link between the law firm and the internet service provider (ISP). Unlike shared connections, where multiple users or organizations share the same bandwidth, dedicated fiber ensures that the law firm has exclusive access to a specific amount of bandwidth, which is not affected by the usage patterns of other customers.
In essence, dedicated fiber offers a direct, high-speed connection between the law firm's network and the ISP's backbone network. This results in faster data transfer rates, lower latency, and a more stable and reliable connection.
Benefits of Dedicated Fiber for Law Firms
There are several benefits of using dedicated fiber for law firms, including:
With dedicated fiber, law firms receive a guaranteed amount of bandwidth that is exclusively available to them, ensuring consistent performance regardless of external factors or other users on the network. This can be particularly beneficial for firms that rely on high-bandwidth applications, such as video conferencing, large file transfers, and cloud-based services.
Improved Reliability and Stability
Dedicated fiber connections offer a higher level of reliability and stability compared to shared connections. Since the connection is not shared with other customers, there is less risk of congestion or network slowdowns. Additionally, dedicated fiber lines are less susceptible to signal degradation and interference, further enhancing the overall connection quality.
Symmetrical Upload and Download Speeds
As mentioned previously, fiber-optic connections often provide symmetrical upload and download speeds, which can be crucial for law firms that require high-speed data transfers in both directions. With dedicated fiber, law firms can experience consistent high-speed performance for both uploads and downloads, which is especially beneficial for applications like video conferencing and large file transfers.
Dedicated fiber connections are highly scalable, allowing law firms to easily upgrade their bandwidth as their needs grow. This flexibility enables firms to adapt to changing demands and accommodate new applications and services without the need for significant infrastructure changes.
Since dedicated fiber provides a direct connection between the law firm and the ISP, it offers an additional layer of security compared to shared connections. The dedicated line minimizes the potential for data breaches and unauthorized access, helping law firms maintain the privacy and confidentiality of their sensitive information.
For law firms with high bandwidth demands, strict reliability requirements, and a need for enhanced security, dedicated fiber can be an ideal solution. By providing a private, high-speed connection with guaranteed bandwidth, dedicated fiber ensures a consistent and reliable online experience, enabling law firms to operate efficiently and maintain client satisfaction. Although dedicated fiber may come with a higher cost compared to shared connections, the benefits it offers in terms of performance, reliability, and security can make it a worthwhile investment for law firms looking to optimize their internet infrastructure.
Overall, understanding how internet connection bandwidth works and its impact on law firm operations is essential for optimizing the online experience and ensuring that critical applications run smoothly. By assessing the firm's bandwidth needs, implementing management strategies, and selecting the appropriate connection type, law firms can ensure a reliable and efficient internet connection that supports their day-to-day operations and promotes long-term success. As law firms continue to adopt advanced applications and services, investing in a high-speed, reliable connection like fiber-optic internet will be increasingly important to maintain productivity and client satisfaction.

Kentucky State Police have a new mobile smartphone app that will change the way KSP interacts with the public.
The app is available in both the Apple and Google Play stores free of charge and allows citizens to report criminal activity, access forms and submit confidential tips in multiple formats. The application is titled KSPOLICE and is available for iPhone, iPad and Android phone users.
Some of the app features include a voice messaging tip line, the ability to send a photo tip, access to the sex offender registry and much more. One component of the app that Brewer is most excited about is the ability to geo-target specific locations within the state with emergency push notifications.
“We can now choose a specific city, county, region or even a particular building and geo-target that location with an emergency push notification message,” says Commissioner Rodney Brewer. “Think about how beneficial this can be to our citizens in regard to traffic issues, severe weather, missing persons or escaped prisoner notifications.”
“With the public’s eyes and ears, we receive crucial information that assists us in solving crimes,” adds Brewer. “This is community policing at its finest for a safer Kentucky. That was the driving force behind this app.”Brewer says the mobile app will enhance the partnership that KSP currently has with local communities by providing an easier, more practical way to send information.
Brewer encourages citizens to download the app and actively participate in crime prevention within their home communities. The app does not replace 911 for emergency situations.
“Keep in mind, when emergencies come up and life is at stake, we want people to utilize the 9-1-1 system. In no way is this mobile app a replacement for that service,” he explains.

In our first decade, ASIAA concentrated on establishing a strong research program in radio astronomy. The assembly of a strong team which can develope its expertise in millimeter and submillimeter wavelength technologies has been the driver for the Submillimeter Array (SMA), the Anisotropy Microwave Background Array (AMiBA), and the Atacama Large Millimeter/submillimeter Array (ALMA) programs. The technical group now has a broad range of capabilities, including superconductor-insulator-superconductor mixers and Superconducting Quantum Interference Device (SQUID) chips, Monolithic Microwave Integrated Circuit (MMIC) devices, IF electronics, cryogenics, correlator, submillimeter wavelength antennas, carbon fiber reflectors, and control software.
In our second decade, ASIAA began to develop a technical group in optical/infrared (OIR) wavelengths. This assembled team has been the driver for the TAOS and CFHT/WIRCam programs. The success of WIRCam collaboration brought the experience of array testing and control electronics to the core expertise of the OIR laboratory. With such expertise, we continue to work on advanced instrumentation project in large telescopes, such as Spectropolarimètre Infra-Rouge (SPIROU) of CFHT and Hyper SuprimeCam (HSC) and Prime Focus Spectrograph (PFS) of Subaru telescope. Negotiation with Japanese space agency JAXA to join the next generation infrared satellite project Space Infrared telescope for Cosmology and Astrophysics (SPICA) is ongoing. In addition, working on the future thirty-meter class telescope instruments is also planned.
The research of instrumentation in ASIAA includes receiver technology development, microwave device design and assembly, superconducting device development, and OIR detector array development. ASIAA will continue to expand on its technical development groups, with the goal of increasing capabilities in detection sensitivity in various domains.

ACTIVEcharge will provide autonomous and self-powered wind turbine blade monitoring services as well as actionable near-real-time information to the turbine controller.
An integrated wireless node (power generator + sensor + wireless transmitter) installed inside a blade transmits the monitoring data wirelessly to the receiver in the turbine nacelle (or elsewhere in turbine housing where the internet is available). The receiver can collect data from multiple sensors. Once the data is collected, data is transmitted to a Cloud platform. We are working with industry partners to integrate our inputs into their control systems.

Alternative / Emergency Communications
When an emergency strikes, most often a natural disaster such as a flood or major snowstorm, some of the first things we do are seek news and information so we can be informed as to what is happening, contact friends and family to check on them and to reassure them that we’re okay, or alternatively, seek emergency assistance. There are many types of emergencies, some forcing people to shelter in place and others forcing people to evacuate, but loss of power make each of them more difficult to cope with. There are many options for keeping in contact. This document is intended to provide basic knowledge about several alternatives.
The most basic requirement is an emergency receiver, something that can be used in almost any circumstance to receive news, weather, and other information. There are quite a few emergency receivers on the market today. Most will receive AM, FM and the National Weather Service. It is essential that the radio have a crank handle so that the battery can be recharged without an external source of power. Most models today also include solar cells for recharging in the sun, and a built in flashlight. Something small and light will be a big advantage, if you are ever forced to travel on foot, with your essential supplies strapped to your back.
Most people today have cell phones, and tend to assume that their service will continue to work in an emergency. The reality is a bit different. When demand is high, cells can reach capacity, leaving many unable to get a dial tone or to receive calls. Typically, officials will request that people not use their cell phones except in dire circumstances, so that first responders can use their cell phones. If a power outage is widespread and lengthy though, the batteries that power the cell towers in those situations can run dry, bringing down the entire cell phone system. With those cautions in mind, it is nevertheless advisable to have a means to recharge your cell phone batteries. Many emergency radios now include a USB socket for just that purpose. It may take some effort to locate a cable to adapt your phone, but keeping that phone available to you is well worth it. There is a company that sells a broad range of charging solutions under the brand name iGo.
What to do then, if you want to prepare for the possible loss of cell phone service? Radio, is the one form of telecommunications that does not depend on someone else’s infrastructure.
Several radio services available to the average citizen, with different power limits:
CB - Citizen’s Band 5 Watts
FRS - Family Radio Service 500 mW (1/2 Watt)
GMRS - General Mobile Radio Service 5 Watts / 50 Watts
XRS - (not a formal FCC service) 1 Watt
ARS - Amateur Radio Service up to 1500 Watts
These services operate in different parts of the radio spectrum:
CB - 11 meters
FRS - 65 cm
GMRS - 65 cm
xRS - 33 cm (Cordless phone spectrum)
Ham - From 160 meters to 24 cm in 16 bands
Due to the nature or radio wave propagation, lower frequencies (longer wavelengths) will generally travel further than higher frequencies.
CB, FRS, and xRS are not licensed.
xRS radios are only available from a single manufacturer.
GMRS is licensed, but there is no test.
The FCC currently grants three classes of license for the Amateur Radio Service:
Each class of amateur license requires passing a technical exam that covers things such as electronics, radio wave propagation, radio design, antenna design, and the FCC rules. There is no longer a Morse Code requirement for any class of Amateur Radio license.
Some important points:
1) None of these services except xRS allow the transmission of encrypted signals. The FCC demands that it be able to monitor all transmissions.
2) Amateur radio may not be used for any commercial purpose.
3) Amateurs train for and have extensive emergency communication capabilities. The Allegheny County Emergency operations center for instance, includes a ham radio station that is manned in emergencies, to expedite the availability of information to first responders.
4) Amateurs for the most part police themselves, and they are serious about it.
5) Like any hobby, there's almost no limit to what one can spend. Basic 2 meter hand-held radios, (HTs, or Handi-Talkies) start at around $100.

B&R introduces a new PLC family: X20 Embedded. The PLCs combine high performance and numerous integrated interfaces in a housing only 55 mm wide. That makes them only half the width of comparable devices.
With their powerful Intel Atom processors, the new PLCs are also suitable for demanding applications with short cycle times. The compact devices can even control a full-fledged robotics application. Machine builders save both costs and cabinet space.
They come standard with two USB ports, an integrated flash memory card and two Ethernet ports. An integrated switch supports daisy-chain cabling without any additional network infrastructure.
The devices feature hardware interfaces for POWERLINK and RS485. The RS485 interface can be used to connect a frequency inverter directly to the PLC without any additional hardware. The power supply is also integrated. Despite the high performance, the PLCs do not require any fans or batteries, making them fully maintenance free.
Optional variants with an interface slot allow the PLCs to support additional fieldbus protocols. All B&R interface cards can be combined with the X20 Embedded series, and all X20 I/O modules can be connected as usual.

Ackcio Mesh – A Reliable LPWAN Standard for Industrial Monitoring
Our world today has become increasingly connected, with every industry relying heavily on automation and digital transformation to survive and thrive. Connectivity plays a crucial role in this.
When it comes to IoT connectivity, there are quite a few technologies that we come across online. Words like LoRaWAN, Sigfox, and NB-IoT are familiar to most of us. In fact, we often use one or more of these technologies in our business for data collection, remote monitoring, or people tracking use-cases. Despite the differences in their underlying technologies, they all have one thing in common—a simple single-hop long-range communication capability from an end device to a centrally placed gateway. Using more technical jargon, we call them Star LPWANs (low power wide-area network).
There is a much more capable and feature-packed alternative—Ackcio Mesh, an interesting networking technology that allows for reliable, real-time, wireless monitoring especially catered for industrial applications.
LPWAN is a general term used to describe a radio technology, proprietary or nonproprietary, that provides long-range communication (up to 1km in urban environments and up to 5km in line-of-sight environments) while operating on small batteries for several years. As such, it offers an order of magnitude improvement in range compared to the other popular radio technologies, like Bluetooth, Wi-Fi, and ZigBee.
Despite being extremely constraint in the amount of data it can transmit at any given time, this technology is gaining traction across a range of industries. Companies like Sigfox and Semtech and captured a fair share of the LPWAN market and many more service providers are fighting for a slice of the IoT Pizza.
A French global network operator, Sigfox builds LPWANs to connect low-power devices (like electricity meters and smartwatches) that require small fragments of data to be periodically pushed to the internet. In some ways, Sigfox functions similarly to a telco; but one key difference is that it operates on a license-free sub-gigahertz radio frequency bands, like 433 MHz (China), 868 MHz (Europe), 915 MHz (Australia and North America), and 923 MHz (Asia).
Being a base-level LPWAN, Sigfox’s proprietary communication technology is limited and only able to transmit a maximum of 140 messages per day to the gateway. With each payload size of up to 12-byte, applications are fairly restricted. Downlink communication is also restricted with only four messages guaranteed to be transmitted on any given day.
Geographical range is another challenge. Although Sigfox is present in up to 70 countries, its usability is limited to regions where its connectivity has been deliberately extended—typically urban areas. But even here, the star topology of the network, obstructions, and other interferences can disrupt connectivity with the gateway.
LoRaWAN is another widely-used LPWAN that operates in the same unlicensed sub-gigahertz radio frequency bands as Sigfox. On the plus side, it does not require a fixed infrastructure by an operator, provides a considerably higher payload strength (up to 250 bytes), and can transmit an unlimited number of messages. Tests have shown an enormous range of communication in near ideal situations with a direct line of sight.
NB-IoT is another promising LPWAN technology that is progressively being rolled out by many Telcos. Like Sigfox, it depends on an infrastructure maintained by network providers. While NB-IoT offers better performance in terms of reliability and higher uplink and downlink capacity, it consumes higher energy (roughly 3 to 5 times higher compared to other LPWANs like LoRa and Sigfox). This makes it less suitable for long-term battery dependent deployments.
Moreover, due to the dependence on fixed infrastructure, it is ill-suited for deployments in remote areas where the coverage is not yet established or not economically feasible for the telcos to setup. Even in urban environments, where the coverage exists, underground applications like tunnels or metro construction suffer.
Ackcio’s Mesh Network offers the same long-range communication as other LPWAN suppliers in the market but with certain key advantages. Our devices form a complex multi-hop mesh network to better route data around obstructions.
When compared with traditional 2.4 GHz mesh networks, Ackcio Mesh Network provides kilometers of range in every-hop, thus allowing for deployments in challenging environments like tunnels and large construction sites and mines.
Ackcio Mesh allows redundant paths in the network to be utilized for data transmission. This prevents data loss due to obstructions, the creation of dead zones within the network, and allows a more distributed data storage for recovery. The complex multihop mesh networking architecture eliminates a single point of failure and makes the network more reliable.
Ackcio Mesh is easily scalable. Not only adding new devices to the network is as easy as just turning them on, but also the addition of new devices to the network also creates many more pathways towards the Gateway and enhances the network coverage. This allows users to set up large network deployments without multiple gateways and allows perfect load balancing.
The widespread adoption of LPWANs, as well as a lack of licensing, have made the sub-GHz spectrum increasingly saturated. This, in turn, leads to severe interference, enough to cause a reduction in bandwidth and an increase in latency. Ackcio Mesh uses multiple frequencies to avoid such interferences. By leveraging an industry-standard Time Synchronous Channel Hopping (TSCH) protocol, Ackcio Mesh transmits data using a different pseudo-randomly selected frequency, thereby avoiding repetitive transmission failure.
Building a Mesh networking protocol is a complicated task as is its deployment and maintenance. To simplify this process, Ackcio Mesh uses RPL, an industry-standard self-healing routing protocol. As such, the deployment process can be as simple as switching on the devices, and the software running on the devices automatically finds the best route to the nearest gateway.
Ackcio Mesh offers network-wide time synchronization down to a few milliseconds, allowing sensor data from different devices within a multi-hop network to be captured simultaneously. This is particularly beneficial to applications that require correlated readings from multiple sensors.
Ackcio Mesh sensors energy-efficient time-synchronized wakeups to exchange information reliably between adjacent devices with automatic time drift corrections and compensation to reduce the radio on time. The devices only wake up when they are supposed to and for a very small amount of time. As a result, they only draw close to 20µA current for over 99% of the time, making the devices last for years on batteries.
Based on IEEE 802.15.4g and IPv6 industry standards, Ackcio Mesh offers multi-hop bidirectional links that allow users to reconfigure devices remotely and collect data on demand. The latter allows users to immediately verify whether an outlier reading is true or a false positive instead of waiting for the next scheduled data transmission.
Being a high-level LPWAN, Ackcio Mesh forms a primary component of Ackcio Beam, our state-of-the-art wireless monitoring system for geotechnical and structural sensors.
Thanks to its unique combination of advanced features, Ackcio Mesh facilitates the wireless transmission of data from remote sensors to our client’s fingertips in real-time, buying them valuable time and intelligence to make timely data-driven decisions. As such, Ackcio Mesh helps distinguish Ackcio Beam as the new industry standard for wireless monitoring applications.

New developments for depot fuelling will include the Merridale vLink data transfer cable which makes its debut at the forthcoming Coach & Bus Live 13, being held at the NEC Birmingham.
Designed to speed depot fuelling, vLink is a rugged snap-on and quick release communications cable which enables the fuelling point to automatically authenticate the vehicle being refuelled.
“Vehicle identification is a cardinal security measure for all depot fuelling facilities,” explains sales director, Stephen Hannan.
“Traditionally this has been covered by using smart keys which are allocated to specific vehicles. The primary function of the keys is to allow the fuelling control software to recognise an authorised vehicle.
[quote]We have created a low investment solution that does not rely upon troublesome nozzle mounted reader devices or difficult to install vehicle filler neck coil devices.[/quote]
“Merridale has refined this technology with the evolution of the read – write capability allowing the keys to store and update information such the type of fuel, restrictions on amount drawn and the vehicle mileage at the previous transaction. This has been carried forward with the development of proximity readers and the Datatag readers introduced last year,” says Stephen Hannan.
“For vLink we are using the same technology but the read/write device – a contact plate, is physically attached to the vehicle. The vLink comprises a mating contact plate with a long reach umbilical cable connecting the dispensing control system to the vehicle. In operation it simply snaps on and off after the completion of the fuelling transaction.”
The core enabling technologies have been developed by MIS Fuel Monitoring in conjunction with the University of Wolverhampton as part of a Government sponsored Knowledge Transfer Programme (KTP) tadalafil citrate 20 mg cialis.
“Our experience has shown that fleet operators want a robust tamper proof solution to replace keys, tags or cards that can be lost, mislaid or transferred without authorisation,” says Stephen Hannan.
“We have created a low investment solution that does not rely upon troublesome nozzle mounted reader devices or difficult to install vehicle filler neck coil devices. Direct data transfer is also a more resilient solution to alternatives such as hand held devices and video vehicle recognition systems.”
The vLink solution can be retro-fitted quite easily to the majority of existing Merridale installations. It can also be used concurrently with smart keys and data tags allocated to contractors or short term hire vehicles or during the interim period as the fleet is being converted to use the new system.
Stephen Hannan concludes. “We are very encouraged with interest shown so far and discussions are under way with a number of launch customers. In particular these are in sectors where vehicles do not have ignition keys or in locations that are especially dirty or hostile. Further developments will see the initiation of a dialogue with the vehicle engine management system, enabling the transfer other data by using the vLink.

With the increasing popularity of Bluetooth-enabled devices, it’s no surprise that many people wonder whether they can use it while flying. Bluetooth technology allows wireless communication between devices, making it convenient for travelers to connect with their smartphones, tablets, and laptops. However, the real question is whether Bluetooth is safe to use on a plane and if it’s allowed by airlines.
Carriers like JetBlue, Southwest, United Airlines and Delta allow travelers to use wireless accessories such as Bluetooth headphones and keyboards while flying, provided they’re in flight mode. Flight mode, as we know, deactivates cellular service while enabling Wi-Fi to stay connected.
This ensures that the passengers can enjoy uninterrupted music, type up their documents, and stay connected with their loved ones. It also ensures that the aircraft’s navigation instruments function properly without any hindrance.
Understanding Bluetooth Technology
Bluetooth technology has become an essential part of modern life, allowing people to connect wirelessly to various devices. It is a wireless communication protocol that uses radio waves to transmit data over short distances. The technology is commonly used for wireless headphones, speakers, and keyboards, as well as for file transfers and mobile payments. The range of Bluetooth typically covers around 30 feet, making it suitable for individual devices.
How Bluetooth Works
Bluetooth works by pairing two devices together, connecting them for wireless communication. When you turn on Bluetooth on your device, it starts transmitting signals in search of other Bluetooth-enabled devices within range. Once it finds a device, it will pair with it and create a secure connection using a unique code. After pairing, the devices can communicate without any wires or cables.
One of the key advantages of Bluetooth technology is that it is incredibly easy to use. Most devices will automatically detect and connect to other Bluetooth-enabled devices within range, without requiring any manual intervention from the user. This makes it an ideal technology for use on planes, where passengers may want to connect their devices to in-flight entertainment systems or other devices.
Common Bluetooth Devices
There are many Bluetooth-enabled devices that can be used on a plane. These include headphones, earbuds, keyboards, and speakers, among others. Bluetooth technology has evolved over the years, and many devices now offer noise-cancellation technology or superior sound quality, making them ideal for air travel.
Wireless headphones and earbuds are particularly popular for air travel, as they allow passengers to listen to music, watch movies, or play games without disturbing others. Many modern headphones and earbuds also offer noise-cancellation technology, which can help to reduce the ambient noise on a plane and create a more immersive listening experience.
Bluetooth keyboards are also popular for air travel, as they allow passengers to work on their laptops or tablets without having to use the cramped keyboard on the plane. These keyboards are lightweight and portable, making them easy to carry in a carry-on bag or backpack.
Finally, Bluetooth speakers are becoming increasingly popular for air travel, as they allow passengers to share their music or podcasts with others. These speakers are small and compact, making them easy to pack in a carry-on bag or backpack. Some Bluetooth speakers also offer waterproofing, making them ideal for use at the beach or by the pool.
In conclusion, Bluetooth technology is a versatile and convenient way to connect wirelessly to various devices. It is an ideal technology for air travel, as it allows passengers to connect their devices to in-flight entertainment systems or other devices. With the wide range of Bluetooth-enabled devices available today, there is sure to be a device that suits every traveler’s needs.
Airplane Mode and Bluetooth
One factor that affects Bluetooth use on a plane is the use of airplane mode. Airplane mode is a setting on your device that disables all wireless functions, including cellular data, Wi-Fi, and Bluetooth. The purpose of airplane mode is to prevent interference with aircraft communication systems, which can be dangerous in some cases.
What is Airplane Mode?
Airplane mode is a setting found on most smartphones, tablets, and laptops that disables all cellular, Wi-Fi, and Bluetooth wireless signals. This mode can be activated manually or automatically when the airplane takes off. The purpose of the airplane mode is to eliminate any wireless signal that could interfere with the aircraft’s electronic systems.
When you activate airplane mode, your device will not receive any calls, messages, or notifications. However, you can still use your device to listen to music, watch movies, or play games that are already downloaded on your device.
It’s important to note that airplane mode doesn’t just benefit the aircraft’s electronic systems. It can also help save your device’s battery life. When you’re in an area with poor reception, your device will constantly search for a signal, which can drain your battery quickly. By activating airplane mode, you can conserve your device’s battery life.
How Airplane Mode Affects Bluetooth
When you activate airplane mode, Bluetooth will also be turned off, as it prevents all wireless signals from transmitting. This may seem like an inconvenience, but it’s an essential safety measure to ensure that no wireless signals interfere with aircraft systems. However, some airlines are beginning to allow Bluetooth usage in flight with certain restrictions.
If your airline allows Bluetooth usage, you can still connect your Bluetooth headphones to your device and listen to music or watch movies wirelessly. However, you won’t be able to connect to the internet or make phone calls via Bluetooth.
It’s important to check with your airline before using Bluetooth on a plane to ensure that you’re following their rules and regulations. Some airlines may require you to keep your device in airplane mode throughout the entire flight, while others may allow Bluetooth usage during certain times.
In conclusion, while airplane mode may seem like an inconvenience, it’s an essential safety measure that ensures the safety of everyone on board. By understanding how airplane mode affects Bluetooth and following your airline’s rules and regulations, you can still enjoy your device’s features while flying.
Airline Policies on Bluetooth Usage
Different airlines have different policies regarding Bluetooth usage during flights. Some airlines strictly prohibit Bluetooth use, while others allow its use with specific restrictions. However, it’s important to note that the use of Bluetooth devices during flights is a relatively new phenomenon, and airlines are still navigating the potential risks and benefits of their use.
Major Airlines and Their Bluetooth Rules
Most major airlines in the US prohibit the use of Bluetooth devices during takeoff, landing, and while the plane is below 10,000 feet. This is because Bluetooth devices can potentially interfere with the plane’s communication and navigation systems, which are critical during these phases of flight. However, some airlines have begun to allow Bluetooth usage above 10,000 feet, where the risk of interference is lower.
American Airlines, Delta, and United Airlines are some of the major airlines that allow limited use of Bluetooth devices. For example, American Airlines allows the use of Bluetooth headphones and speakers, but not Bluetooth keyboards or mice. Delta allows the use of Bluetooth headphones and speakers, but not Bluetooth keyboards or game controllers. United Airlines allows the use of Bluetooth headphones and speakers, but not Bluetooth keyboards, mice, or game controllers.
Southwest and Alaska Airlines currently do not allow Bluetooth usage, citing safety concerns. However, both airlines continue to monitor the latest developments in Bluetooth technology and may revise their policies in the future.
International Regulations on In-Flight Bluetooth Use
International regulations on in-flight Bluetooth use vary by country. For example, the European Aviation Safety Agency (EASA) allows the use of Bluetooth devices, provided they are in “flight mode” and not connected to any other devices. This is because EASA has determined that Bluetooth devices in flight mode do not pose a significant risk of interference to aircraft systems.
On the other hand, the Civil Aviation Administration of China (CAAC) prohibits the use of Bluetooth devices during all phases of flight. This is because CAAC has determined that even Bluetooth devices in flight mode can potentially interfere with aircraft systems, and the risk is too great to allow their use.
It’s essential to check with your airline or country’s aviation authority for specific regulations regarding Bluetooth usage. As technology continues to evolve, so too will the policies and regulations surrounding Bluetooth use on airplanes.
Potential Interference with Aircraft Systems
While Bluetooth use is generally considered safe, there’s still a possibility that it could interfere with aircraft systems. The possibility of interference depends on how close the device is to the aircraft’s electrical systems.
Bluetooth technology has become an integral part of our daily lives, allowing us to connect and communicate with various devices wirelessly. However, when it comes to air travel, the use of Bluetooth devices can be a cause for concern. The Federal Aviation Administration (FAA) has strict rules and regulations in place to ensure the safety of passengers and crew members aboard aircraft.
How Bluetooth Signals Could Affect Avionics
Bluetooth signals transmit at a frequency of 2.4 GHz, which is the same frequency used by many aircraft systems. This frequency is also used by other devices such as Wi-Fi routers, microwaves, and cordless phones. However, Bluetooth signals are usually weaker than those used by avionics systems, making the possibility of interference low. Additionally, aircraft systems are well-shielded, reducing the chance of interference even further.
The FAA has conducted numerous studies and tests to determine the potential impact of Bluetooth devices on aircraft systems. These studies have shown that the risk of interference is minimal, and the likelihood of a Bluetooth device causing any significant damage to an aircraft’s avionics is extremely low.
Safety Precautions Taken by Airlines
Despite the low possibility of interference, airlines take precautions to ensure the safety of passengers and the aircraft. Some of these measures include additional shielding on aircraft systems and testing Bluetooth devices to ensure they won’t cause interference. Airlines also require passengers to turn off their Bluetooth devices during takeoff and landing, as these are critical phases of flight where any interference could potentially be more dangerous.
In conclusion, while the use of Bluetooth devices on airplanes may seem like a cause for concern, the risk of interference is minimal. The FAA and airlines take the safety of passengers and crew members very seriously and have implemented numerous measures to ensure that Bluetooth devices do not pose a threat to aircraft systems. So, the next time you’re on a flight, feel free to connect your Bluetooth headphones and enjoy your favorite tunes without worry.
Tips for Using Bluetooth on a Plane
When using Bluetooth devices on a plane, there are some tips to keep in mind to ensure a smooth experience.
Pairing Devices Before Boarding
It’s a good idea to pair your Bluetooth devices before boarding the plane. This will allow you to start using them as soon as Bluetooth use is permitted. Additionally, pairing before boarding will ensure that you won’t interfere with other passengers’ devices during the pairing process.
Using Bluetooth Headphones and Earbuds
Bluetooth headphones and earbuds are an excellent way to listen to music or watch a movie during a flight. Many headphones offer noise-cancellation technology, which can block out the noise of the plane’s engines. However, it’s essential to keep volume levels low to avoid disturbing other passengers.
Troubleshooting Bluetooth Issues In-Flight
If you experience issues with Bluetooth during a flight, there are some steps you can take to troubleshoot the problem. First, make sure that your device is correctly paired with the Bluetooth device. Additionally, try resetting your Bluetooth device or turning it off and back on again. If the issue persists, try moving closer to the Bluetooth device or restarting your device.

PACid has been the leader in dynamic encryption of data since the 1990s. The first generation of the company’s technology is a part of the Wi-Fi security standards. The company has been continuing to innovate ever since and has technology that could put a stop to widespread theft of sensitive information online.
PACid founder Guy Fielder’s inventions were fundamental to dynamic encryption as used in the 802.11i Wi-Fi security standard otherwise known as Wi-Fi Protected Access 2 (WPA2), introduced in 2004.
Security is even more of a concern for wireless communications than for wired communications because Wi-Fi is essentially a form of radio, which has traditionally been easy to intercept. Without a security protocol in use, anyone in range of a Wi-Fi signal could overhear voice communications and read data transmissions.
Wi-Fi security requires:
- Confidentiality, protected via encryption
- Verification of authenticity (users are who they say they are)
- Verification of message origin
- Control of access to network services
- Protection against jamming
- Protection against hijacking or altering data packets
The 802.11i standard defines a security mechanism that operates between the Media Access Control (MAC) sub-layer and the Network layer. It provides a Robust Security Network (RSN) with two new protocols: the 4-Way Handshake and the Group Key Handshake.
BoSS™ (Bolt-on Strong Security)
PACid has continued to innovate in the area of data security and is again at the leading edge of dynamic security technology with our BoSS (Bolt-on Strong Security) solution.
PACid’s BoSS solution is a strong dynamic password-based authentication and dynamic encryption platform designed to significantly increase the security of password-based authentication, while remaining transparently backwards-compatible with most legacy applications and databases.
With the BoSS system, end users can use the same password for all of their websites and applications on one secure mobile device, while the system deploys a one-time-use password to authenticate the end-user to the host application. This eliminates the need for multiple user passwords, while still maintaining online security.
Our motto is: “In God we trust, everyone else gets dynamically authenticated.”
PACid’s System Levels Approach to Data Security
PACid offers a layered approach to data security. We have developed technology that can be deployed in different ways with different levels of end-to-end security.
What we call “Level 1” is a software-only implementation, which provides enhanced security but would still be vulnerable to different kinds of snooping attacks.
Our “Level 5” solution would be the ultimate in data security, using a special purpose (secured island) processor within the general purpose computing device.

We are using AD9283 expansion module.. Setup: Feeding 3.3V 40MHz square wave; 180mV, 5 MHz single ended sine wave (at high Z) to the Ain+ SMA input, collecting the output samples into a PC and processing the samples in Matlab. Function generator, clock source and data collection system are all high end equipments. Input clock, 5.0V power supply, and the input analog signal are all clean. Observation: Sample values range from about 40 to about 250 (as seen from the Matlab time domain plot), a bit noisy.. When we compute SINAD using Matlab function, we get about 35 dB. However we expect about 47-48 dB of SINAD as per the data sheet of AD9283.. 13-14 dB is a huge degradation. Appreciate any suggestions/ thoughts.

MPLS vs VPN
When comparing IP VPN and MPLS, the main differences are in the quality of service, who is in charge of the network management, and who has visibility within the network for wireless backhaul and remote locations.
The most important difference that sets apart IP VPN from MPLS is its point-to-point connection. For example, suppose a company with IP VPN has five sites, each site has a tunnel to and from each other site. So these five sites would equate to (5*(5-1))*2 or 40 unidirectional tunnels.
As opposed to IP VPN, MPLS is designed as a multipoint technology. There are no tunnels in MPLS; when site 1 needs to communicate with site 2, it looks up the site through the routing table, adds a distinct label that denotes the site, and then sends the packet across the MPLS backbone to the next router.
IP Virtual Private Networks and Multi-Protocol Label Switching are frequently used with no regard for any fundamental differences. However, at the same time, MPLS is now such an integral part of networks, to compare the two would be almost fruitless. It is a commonly held belief that IP VPNs and MPLS are nearly interchangeable. To further confuse the issue, in the network industry we tend to use the two terms synonymously, but IP VPNs and MPLS are obviously different.
Comparisons between these two technologies sometimes may fail to mention the fact that IP VPNs in many cases rely on an MPLS infrastructure. The equipment that runs IP VPNs and MPLS jointly is also expected to be utilizing VPLS and dedicated Internet access, as well as Layer 2 VPNs.
MPLS has become a major technology that is used in the universal platform on which all these other services operate. A company running IP VPN services is likely to be running through an MPLS backbone.
Although MPLS equipment may provide IP VPN connections, the VPN and MPLS methods have their differences. There are a number of considerations your customers need to weigh in on when designing their networks around either.
Flexibility is the first of these considerations. VPNs are very flexible and dynamic for building larger networks with many small endpoints. The carrier partner can direct and provide performance assessments more easily. Despite their large size, VPNs are very configurable for the customer.
Management also comes into play. In most cases, your customer manages their VPN. The VPN for an MPLS service, on the other hand, is taken care of by the backhaul carriers.
Services and Security
Another consideration should be security and services. If your customer requires traffic prioritization and management, VPN might fall short of MPLS in their service capabilities. The fact that VPNs run on the open Internet may lead to privacy issues; which leads to within-network privacy. Although MPLS does not have encryption by default, it may be added to keep peeping Toms from reading or writing on customer files, in the unlikely event that access is possible though MPLS.
Encryption, simple authentication, and everything in between also has an effect on security, of course. The customer’s configuration may prove an important factor in whether MPLS or VPN is appropriate for them.
It is said that “cash is king,” so your customer may be more concerned with pricing than anything else. VPN is very often made cheaper by network operators. Each megabyte per second in MPLS can fall between $300 and $600, according to a Network World report. Connections on fiber MPLS can rack up double the charge.
Even then, North American and Western European customers pay less than their counterparts in other regions, as pointed out by TeleGeography, a research firm. In 2010, the median cost per month for a 1.5-Mbps MPLS IP VPN port.
The difference between VPNs and MPLS might be negated in the price aspect by vendors. Some vendors charge per port, regardless of network method.

The unique identifier of a machine (Computer, printer etc) on a computer network which uses TCP/IP protocol for communication is called IP address. There are two types of IP versions are in use, one is IPv4 and another one is IPv6. IPv4 address has a size of 32 bits and consists of 4 decimal numbers separated by dot, each part ranging from 0 to 255 and is a group of 8 bits, for an example 184.108.40.206. In IPv4, there are 232 possible combinations which offer a total of 4,294,967,296 unique addresses. On the other hand IPv6 has a size of 128 bits and approximately 3.403x1038 unique addresses, a typical example of IPv6 address is 0:0:0:0:0:ffff:f37:63ff.

THE EQUIPMENT list
The arrival of the Army and the entry of the U.S. into World War II transformed Camp Evans into a major center for radar research and antenna production. Project Diana, however, introduced a whole new series of challenges beyond the reach of existing technology designed for (relatively) short-distance detection of enemy aircraft. As DeWitt knew from the start, only a very special combination of transmitter, receiver, and antenna would do the job. A major constraint in addressing these challenges was the lack of either time or budget to design and purchase new equipment; everything depended on modification of equipment already on hand.
Early on, Jack DeWitt decided to use as a starting point the crystal-controlled FM transmitter/receiver specially designed for the Signal Corps by radio pioneer Edwin Howard Armstrong. Armstrong’s transmitter was in turn based on the “Old Faithful” SCR-271, bedspring-type array antenna, which could operate at a wavelength of 2.7 meters—short enough, DeWitt and his team believed, to penetrate the ionosphere.
The Armstrong set had features that could be adapted to address two important problems:
First, due to the relative velocities of the earth and moon, the frequency of the returning echo differed from the transmitted signal (a phenomenon known as Doppler shift) by as much as 300 Hz, a number that was constantly changing depending on the earth’s rotation and the moon’s orbital path. To ensure that the outgoing signals would bounce back and then be detected by the receiver, recalculation of the earth’s position relative to that of the moon and the resulting Doppler frequency shift was required for each attempt; this work was carried out by the mathematician Walter McAfee of the Theoretical Studies Group. The modified Armstrong radio was capable of being fine-tuned to the exact frequency required to compensate for the Doppler shift at a given point in time.
Second, signals bounced off an object 240,000 miles from earth would take much longer to echo and be much too weak to be detected by receiving antennas then in use, a problem that had bedeviled previous attempts to shoot the moon. Several steps were taken to enhance the detectability of the echo. “We realized that the moon echoes would be very weak,” DeWitt later recalled, “so we had to use a very narrow receiver bandwidth to reduce thermal noise to tolerable levels.” In addition, the power of the transmitted signal was increased. To further augment the returning signal, it was decided to generate a much longer pulse that would be easier to detect. The Armstrong radio was one of the few existing sets capable of generating such a long pulse.
Echoes were received as blips on a nine-inch cathode-ray tube and as 180 Hz beeps.
The iconic bedspring antenna
To ensure successful reception of the echo, however, an even larger problem remained to be resolved, that of antenna sensitivity. No antenna on-site was up to the job. To come up with a solution, DeWitt called on two very senior specialists from the Antenna Design Section, one the Section head, who proposed a clever system using quarter-wave step-up transformers. The only problem: It didn’t work, even after extensive efforts to tweak the transmitter.
DeWitt then turned to his own little group, which came up with the inspired idea of positioning two SCR-271 stationary radars side-by-side to create an enormous (40x40-foot) double bedspring antenna consisting of an 8x8 array of 64 half-wavelength dipoles with reflectors that further enhanced the 111.5 MHz signals. Herbert Kauffman, writing in 1946, credits King Stodola, Harold Webb, and Jack Mofenson with developing this approach. Translating that idea into reality was undoubtedly easier said than done, but the Mechanical Design Section was able to implement this alternative plan and assemble the antenna that eventually became the lynchpin of the operation. The resulting array was 152 times (~22 decibels) more sensitive than a single dipole. Unfortunately, engineering specifications were destroyed by the Army in 1971, so the exact design details are unknown.
This whole assembly was mounted atop a 100-foot reinforced tower in the northeast corner of Camp Evans. The heavy and ungainly antenna could not be tilted, it could only be rotated in azimuth; so moonshots could only be attempted twice a day, usually at moonrise but occasionally at moonset, during the 40-minute window that opened when the moon passed through the 15-degrees-wide beam of the antenna pattern.

The SPL 2Control combines speaker and headphone monitoring control with innovative features in an attractive high-quality package. The all-analog 2Control allows for connection and selection of two stereo input sources, two stereo speaker sets and two headphones. A third mono speaker output can feed a sub woofer. Speaker volume is controlled by the central, massive volume potentiometer. Each headphone output is fed by its own amplifier stage and can be controlled independently. Mono and DIM switches provide further necessary monitoring functions.
The key function is undoubtedly the crossfeed control, a new innovation from SPL. It simulates frequency-dependent interaural level differences from both channels so that the super stereo effect on headphones can be adjusted to the stereo width of a given speaker set, which essentially means that the user is able to adjust the crossfeed with the headphones to match the stereo imaging of the speakers in the room. This is a new and unique feature which allows audio to be mixed on headphones.
The 2Control addresses all DAW users in audio mixing and AV production with the need for monitoring control and is especially effective in avoiding acoustically problematic environments (desktop workspaces, recording mobiles etc.).

Peter deserves all the credit for designing this great antenna. All I did was tell people about it. I believe a commercial version of the design is now available from VHF Teknik in Sweden.
Glad to hear you're using a preamp with the XDR-F1HD. Its adaptive noise reduction greatly reduces noise in stereo, but it doesn't function in mono and can't benefit mono DXing. The tuner does not have an RF amplifier stage so its noise figure is rather high (8.5 dB, about the same as a Technics ST-9030). Adding a low-noise preamp can really improve S/N for weak signals. As you note, the preamp gain covers up the soft-muting, which can be annoying at low signal levels. It also holds off the high-cut noise filter and this can improve intelligibility when trying to ID a weak station.

Before the COVID-19 pandemic, major disruptions to the fast food industry hailed from the development of new technologies and the implementation of smarter systems. Post-pandemic, the physical dimension of human/computer interactions was elevated for the first time. In this smart solution, Wavicle’s team developed a novel method to improve the proximity required in human/computer interactions by developing a personalized smart application with gesture recognition through audio-video stream analytics.
Developing a customer gesture recognition system
Wavicle built an end-to-end data science embedded solution using data from all audio and video systems that leverage machine learning and advanced analytics capabilities to convert gestures to speech. This artificial intelligence (AI) powered solution is deployment-ready with American Sign Language detection. It can also customize gestures to speech recognition.
The platform relies on custom AI algorithms to identify gestures and is built on the perceptual computing user interface. A custom portal allows the recognized gestures to generate text and then generate audio output from the text model. Customer responses are captured, analyzed, and used to refine the AI model continuously, and reinforcement calibrations are under development.
Creating safety with customization
Bringing together all customer gesture data in one platform with already available standard gestures for American Sign Language has allowed Wavicle’s team to develop personalization in the video analytics space. In turn, this drives customer engagement and safety during pandemics and increases physical dimensionality for customers.
Previously challenged by customer adaptations and technology latency due to the amount of analyzable data, companies were reluctant to explore the path of customized smart systems. The COVID-19 pandemic has forced businesses to adapt to newer technologies with consideration of the physical dimension. With AI-based smart tools, companies have new ways to engage customers in safer environments.

Public Key Cryptography, also known as asymmetric cryptography, is a cryptographic system that uses a pair of keys: a public key and a private key. Each key can be used to encrypt or decrypt data, but the keys are not interchangeable.
The Public Key Cryptography system works by using a pair of keys, one public and one private. The public key is known to everyone, and can be freely distributed. The private key, on the other hand, is kept secret and known only to the owner of the key pair.
To send an encrypted message to someone using Public Key Cryptography, you would use their public key to encrypt the message. Once the message is encrypted, it can only be decrypted by the owner of the private key.
Similarly, if someone wants to digitally sign a message, they would use their private key to sign the message. Anyone with access to the public key can then verify that the message was indeed signed by the owner of the private key.
The security of Public Key Cryptography is based on the fact that it is computationally infeasible to determine the private key based on the public key. This is known as the “computational hardness assumption”.
The algorithm used in Public Key Cryptography is typically based on mathematical problems that are easy to solve in one direction, but difficult to solve in the opposite direction. For example, the RSA algorithm is based on the fact that it is easy to multiply two large prime numbers together to obtain a composite number, but it is much harder to factor that composite number back into its original prime factors.
In summary, Public Key Cryptography provides a secure way to exchange messages and digital signatures over an insecure network. It allows users to communicate securely without having to share a secret key.
RSA (Rivest-Shamir-Adleman) is a public-key cryptosystem that is widely used for secure data transmission over the internet. It was first proposed in 1977 by Ron Rivest, Adi Shamir, and Leonard Adleman. RSA encryption is based on the fact that it is easy to multiply two large prime numbers together, but it is difficult to factor the product of two large prime numbers back into the original primes. This mathematical problem forms the basis of RSA encryption and decryption.
The RSA algorithm involves three main steps: key generation, encryption, and decryption.
Key Generation: In RSA, each user has two keys: a public key and a private key. The public key is shared with others and used for encryption, while the private key is kept secret and used for decryption. The key generation process involves the following steps:
1.1 Select two large prime numbers p and q.
1.2 Compute n = p * q.
1.3 Compute Φ(n) = (p - 1) * (q - 1), where Φ is the Euler’s totient function.
1.4 Select a random integer e such that 1 < e < Φ(n) and e is co-prime to Φ(n).
1.5 Compute d such that (d * e) mod Φ(n) = 1.
The public key is (n, e), while the private key is (n, d).
- Encryption: To encrypt a message M, the sender uses the receiver’s public key (n, e) to compute the ciphertext C as follows: C = M^e mod n
Where ^ denotes exponentiation and mod is the modular operation. The ciphertext C can be sent to the receiver over an insecure channel.
- Decryption: To decrypt the ciphertext C, the receiver uses their private key (n, d) to compute the plaintext message M as follows: M = C^d mod n
Where ^ denotes exponentiation and mod is the modular operation. The plaintext message M can then be read by the receiver.
The security of RSA is based on the fact that it is difficult to factor the product of two large prime numbers. An attacker would need to factor n into its prime factors in order to compute d from e, but the factorization problem is believed to be computationally infeasible for large enough values of p and q. Therefore, the security of RSA depends on the size of the key, which is typically 2048 or 4096 bits long.
RSA has become one of the most widely used public-key cryptosystems in the world, used in applications such as secure email, online banking, and digital signatures. However, it is important to note that RSA is vulnerable to attacks if the keys are not generated properly or if the implementation is flawed. Therefore, it is important to use secure key generation techniques and to ensure the proper implementation of RSA.

Whether you’re running a small business from home or are the owner of a multi-national firm, it’s essential to have a strong network to conduct your transactions and communicate. A slow speed can do more than just serve as a nuisance – it could cost you clients or hinder meetings. If your network has been operating at a less than optimal level lately, here are a few options to help you get it up and running at lightning-fast speeds.
It’s important to realize that internet speed depends on many different factors. In addition to the network you’re using, something as simple as router placement could have a serious impact on the speed you experience.
1. Move your router position.
It seems like technology should have moved past this basic problem by now, but one of the primary issues that can impact network speed is the location of your wireless router! A wall or door can block the signal, while other devices in the home can cause interference. To avoid these common problems, simply move your router up to a higher position. If you’re in an office building, try moving it as high and central as you can. Smart routers are also available. These can automatically adjust for interference, although you may still need to move them higher if there are lots of cubicle walls.
2. Clean up your devices.
A cluttered up computer or smartphone could also be the culprit to your business networking woes. Close unnecessary apps and updates when you’re not using them, which should have an instant impact on your speed. There are a number of apps that will control this for you.
3. Update your operating system.
Are you still using an ancient operating system? Although it may be working fine, it can have an impact on your networking speeds. If you haven’t done it yet, upgrade to the latest version of your device’s operating systems. The web browser you’re using will also have an impact, so look at upgrading this to the latest standard as well.
4. Use a powerline adapter.
If you’re unlucky enough to have an office in a location where the signal is weak, you could use a powerline adapter to boost it. These use existing power lines to boost the signal as you move from room to room.
5. Update your provider or plan.
If you’ve just recently launched a business, you may still be working with a personal plan. This could mean that you’re sharing your connection with loads of other people, which naturally slows down the overall speed and efficiency. Try running speed tests at different times of day to see if this is the culprit. If this is the case, you may want to look at options like Nokia Networks that specialize in optimizing networks and reducing congestion. Otherwise, upgrade to a business plan so that you can hog all of the speed for yourself. The server location could have an impact on your speed as well – look at all networking options.
These are just a few ways to boost your network speed. By following them, you may see that your business’s productivity speeds up at the same time!

Q & A
《Q108》 For the BSI-3.3S12R0F, is the S-GND (pin #2) on the GND side of the remote ON/OFF connected to the -Vin (pin #4) connected internally? Can it be connected to -Vin?
The S-GND and -Vin are connected internally. Therefore connecting to the -Vin pin is possible however since large currents flow through -Vin, a voltage difference between GND may occur. Therefore using the S-GND pin is recommended

To learn about the mobile phone, it is good to understand how technology has evolved. Mobile phones were initially used for voice and text communication which was very expensive in those days. But now we are able to do all sorts of tasks from one device such as taking photographs, watching movies or even playing games on our mobile phones. There are many more benefits that will come with this new technology so I hope you can enjoy the essay!
Mobile phones are devices that are important to students and children. They allow them to stay connected with their parents, friends, and the world in general.
The term “mobile phone” is a mixture of two words: “mobile” and “phones,” where “phone” refers to an electronic device used for communication, and “mobile” refers to the device’s ability to be readily transported from one location to another.
Mobile phones nowadays are so tiny that they can easily fit in the palm of your hand and are also extremely light in weight. People nowadays use cell phones as if they were oxygen, since they utilize them for almost everything in their lives.
Following the rise in internet use, mobile phones have become a benefit to everyone, as they can be used for anything from buying tickets to video chatting and a variety of other essential tasks.
Nowadays, there is also online shopping, which can be done using a phone, where you can sit at home and buy anything from the internet, and it will be delivered to your house in a short period of time.
The cell phone is very helpful, and it has played a significant role in the growth of both human civilization and the different companies that exist around us. The keypad on mobile phones connects us to individuals all over the world, and we may speak to them at any moment.
People may now make money by investing in stocks, bonds, or money via e-trading, often known as electronic trading.
Mobile phones may also be used for educational purposes, in which students search the Internet for information on any topic and get complete information on that subject, as well as other information such as general knowledge, which improves IQ.
The most common usage of mobile phones is for entertainment, with individuals using them to view movies or listen to music. Nowadays, mobile phones have everything: a flashlight that can be used as a torch, a camera that can be used to record movies and take photos, and GPS that can be used to find your position and navigate.
There are a slew of benefits to phones, but there are also a slew of drawbacks. The major drawbacks of mobile phones are that they emit radiation, which is harmful to your health, and that using them for long periods of time strains your eyes and causes nausea. Mobile phones are a source of distraction for students who have abandoned their academics to use their phones for pleasure.
Because the phone is the most distracting device, many people have been harmed, resulting in hazardous situations such as individuals using the phone while driving a vehicle, who may be involved in a dangerous accident in which they may enjoy themselves or lose their lives.
As good as mobile phones are for communication, they also degrade the standard of communication because face to face communication is better because we can read the body language of the person with whom we are communicating, but it is impossible to read a person’s body language while communicating over the phone.

We’ve started a new project to install new WiFi infrastructure across the marina which will, when completed, provide high speed Internet connectivity across the entire marina.
The new infrastructure will provide separate WiFi access for vessel telemetry e.g. chart plotters etc, berth holders, and the public. The project involves installing a higher density of access points, which will give greater coverage and faster speeds, however this sounds a lot simpler than it actually is.
The project is being led by our own electrical engineer, Ben Martel, who has over 20 years experience with cellular and WiFi technology. Ben explains that “marinas are a uniquely challenging environment to provide high speed WiFi with consistent coverage.”
WiFi uses radio waves to transmit information between your device and the WiFi router. When these radio waves hit an obstruction, which in the case of a marina are masts and vessels, it weakens the strength of the radio signal beyond the obstruction.
In a marina it is further complicated because the tide changes the environment constantly. “We have to carefully plan where in the marina we install the new WiFi access points to ensure that the additional access will compensate for the obstructions” says Ben.
The new WiFi access points that you will start seeing pop-up on the marina piers support the latest WiFi standard, known as WiFi 6, but they support all the previous versions as well. What’s new in WiFi 6? The crux of WiFi 6 is MU-MIMO (Multi-user multi-in multi-out). What this means, as the picture shows, is the WiFi access point has four external antennas.
The radio signal from your WiFi station e.g. phone, tablet, chart plotter etc, is received by all four antennas. The received signal on each of them is compared to each other, making sure that any ‘noise or corruption’ received can be removed. This significantly reduces the amount of times that the access point needs to ask the station to re-transmit it’s message.
“Think of yourself talking to four other people at the same time; if every time you spoke, all four of the other people confirmed with each other what they heard, then agreed between themselves what was actually heard. The conversation would surely proceed with a lot more certainty” says Ben.
The project will initially be rolled out on Piers A, B, and C, starting in the first weeks of May, and then tested to ensure that service is to be as effective as possible; the remaining piers will have the new WiFi installed in the months following.

A non-electrical, low cost piece of glass replicates a machine’s neural network in order to recognise handwritten digits.
University of Wisconsin–Madison engineers developed a piece of glass containing small impurities that act as artificial neurons. These impurities bend light reflected from the image of a digit in a particular way to be able to identify it.
UW-Madison electrical and computer engineering professor Zongfu Yu said: “We’re using optics to condense the normal setup of cameras, sensors and deep neural networks into a single piece of thin glass.
“The wave dynamics of light propagation provide a new way to perform analogue artificial neural computing.”
The impurities within the glass consist of air bubbles of different shapes and sizes, as well as small pieces of light-absorbing materials, such as graphene.
Light that reflects from the digit enters at one end of the glass and then, due to the impurities, focuses to one of nine spots, numbered from one to nine, on the other side.
The glass could detect a handwritten 3, and then again as it was altered to become an 8.
The glass – which would, of course, work at the speed of light – could act as an alternative to currently used smart glass that requires sensors or electricity.
One piece of image recognition glass could be used hundreds of thousands of times. It could be used as a biometric lock on a smartphone, as an example.
“We could potentially use the glass as a biometric lock, tuned to recognise only one person’s face,” Yu said. “Once built, it would last forever without needing power or internet, meaning it could keep something safe for you even after thousands of years.”
The research team – which published details of their proof-of-concept in Photonics Research – plan to determine whether the glass works for more complex tasks such as facial recognition.
“The true power of this technology lies in its ability to handle much more complex classification tasks instantly without any energy consumption,” said collaborator Professor Ming Yuan at Columbia University.
“These tasks are the key to create artificial intelligence: to teach driverless cars to recognize a traffic signal, to enable voice control in consumer devices, among numerous other examples.”

|◄ ► The World's First Text Message (1844) - "What Hath God Wrought?" • Connie Rohman|
Telegrams were the first text messages. Morse Code was invented by Samuel Morse in 1836. On May 24, 1844, Morse sent the first long distance telegraph message, "What hath God wrought?" from Washington, D.C., to Baltimore. Much as modern electronic communications have transformed our modern world, the telegraph changed politics, culture, the economy, even warfare. If you have seen the movie "Lincoln," you saw the critical role those short messages played in the Civil War.
This piece is from my Lost Modern Language Series. This series presents a visual interpretation of the dots and dashes of Morse Code, enabling the viewer to "read" the artwork. The piece reads, "What Hath God Wrought." The longer rectangular boxes are the ""dashes,"" with the shorter ones being the "dots." The corresponding letter of our traditional alphabet is quilted inside the Morse Code symbols.
Techniques used include piecing, hand guided machine quilting.

When you connect to a VPN, a “tunnel” is created between your device and the VPN server. All of your internet traffic is routed through this tunnel, so your data is secure from prying eyes. But how does this tunneling process work?
Checkout this video:
Introduction to VPN Tunneling
A Virtual Private Network (VPN) is a way of using a public telecommunication network, such as the Internet, to provide private resources and user access. A VPN can connect multiple sites, over either private or public networks. The encryption of communications between VPN sites provides security and protection against eavesdropping.
Tunneling is a process of encapsulating data within another data packet. In the context of a VPN connection, tunneling allows private network traffic to be transmitted over a public network, such as the Internet.
There are two types of tunneling: layer 2 tunneling protocol (L2TP) and point-to-point tunneling protocol (PPTP). L2TP is more secure than PPTP, but both protocols provide similar functionality.
In order to set up a VPN connection, you will need to have access to a VPN server. Many VPN providers offer both L2TP and PPTP access to their servers. Once you have access to a server, you can use either L2TP or PPTP to connect to it.
L2TP uses UDP port 1701, while PPTP uses TCP port 1723. To connect to a VPN server using L2TP, you will need to use an L2TP client software program. There are many different L2TP client programs available, both free and paid. Once you have installed and configured an L2TP client program on your computer, you can use it to connect to an L2TP-enabled VPN server.
To connect to a VPN server using PPTP, you will need to use a PPTP client software program. There are many different PPTP client programs available, both free and paid. Once you have installed and configured a PPTP client program on your computer, you can use it to connect to a PPTP-enabled VPN server.
How Tunneling Is Accomplished in a VPN
Tunneling is a process of encapsulating data within another data packet. When you tunnel data, you add an extra layer of protection because the data is less likely to be tampered with or intercepted. VPNs use tunneling to protect your data as it travels across the internet.
Layer 2 Tunneling Protocol (L2TP)
Layer 2 Tunneling Protocol (L2TP) is a tunneling protocol used to support virtual private networks (VPNs) or as part of the delivery of services by ISPs. It does not provide any encryption or confidentiality by itself. Rather, it relies on an encryption protocol that it passes within the tunnel to provide privacy.
L2TP was first published in 1999 as an enhancement to PPTP. In 2005, the L2TP over IPsec standard was published by the Internet Engineering Task Force (IETF). Today, L2TP is considered more secure than PPTP because it uses stronger encryption algorithms and offers additional security features.
L2TP is typically used with the IPsec protocol to protect data transmissions over public networks such as the Internet. When used in this way, L2TP is often referred to as L2TP/IPsec (layer 2 tunneling protocol/internet protocol security).
To set up an L2TP/IPsec VPN, you will need the following:
-A router that supports L2TP/IPsec connections
-A computer or mobile device with an operating system that supports L2TP/IPsec
-An Internet connection
-The IP addresses of the VPN server and your computer or mobile device
-The preshared key for your router (this is usually provided by your ISP)
Point-to-Point Tunneling Protocol (PPTP)
Point-to-Point Tunneling Protocol (PPTP) is a method for implementing virtual private networks. PPTP uses a control channel over an IP network, as well as GRE (Generic Routing Encapsulation) to encapsulate PPP frames. PPTP has been implemented on a variety of platforms, including Windows, Linux, and iOS.
When using PPTP, a VPN client first establishes a connection to a VPN server. The VPN client then authenticates with the server and negotiates a security policy. After the security policy is negotiated, the VPN client and server use GRE to encapsulate and send data packets. Data packets that are sent over the IP network are encapsulated with a GRE header and trailer.
GRE is a tunneling protocol that can encapsulate a variety of protocols, including IP, inside of it. When using GRE, each data packet is assigned a sequence number. The VPN client or server can use this sequence number to reassemble data packets that have been split into multiple pieces.
The use of GRE allows PPTP to tunnel other protocols besides IP, such as AppleTalk orIPX/SPX . In addition, GRE can be used to tunnel multicast traffic .
Secure Socket Tunneling Protocol (SSTP)
SSTP uses a SSL/TLS connection which offers a higher level of security by encrypting all traffic going through the tunnel. To prevent tampering and ensure that only authorized users can access the network, SSTP uses both server and client authentication. This two-way authentication process ensures that only authorized users can gain access to the network and that data passing through the tunnel is not tampered with.
To set up an SSTP connection, the user first needs to obtain a SSL/TLS certificate from a trusted Certificate Authority (CA). The user then needs to install the certificate on both the client and server machines. Once the certificate is installed, the user can configure the VPN software to use SSTP as the tunneling protocol.
SSTP is only available on Windows Vista SP1 and later or Windows Server 2008 and later.
Internet Protocol Security (IPsec)
Internet Protocol security (IPsec) is a secure method of data transmittal that uses encryption and other security measures to preserve the confidentiality, integrity, and authenticity of data in transit. IPsec is often used in Virtual Private Networks (VPNs) to provide a secure connection between two or more networks, or between a network and an individual user.
Tunneling is the process of encapsulating data in one protocol so that it can be transmitted over another protocol. In tunneling, the original data packet is encapsulated in a new packet with a new header that contains instructions for how the packet should be routed. The receiving computer strips off the new header and forwards the original data packet to its destination according to the instructions in the original header.
Tunneling is a key component of IPsec because it allows data to be securely transmitted over public networks such as the Internet. Without tunneling, data would have to be sent in plain text, which would make it vulnerable to interception and tampering. By encapsulating data in an IPsec tunnel, businesses can create VPNs that allow employees to securely connect to their corporate network from anywhere in the world.
There are two main ways to accomplish tunneling with IPsec: Transport Mode and Tunnel Mode.
In Transport Mode, only the data payload is encrypted; the headers are left intact. This is typically used for communicating between two hosts, such as when an employee uses a VPN client to connect to their company’s network from their home computer.
In Tunnel Mode, both the data payload and headers are encrypted. This is typically used for creating site-to-site VPNs, where traffic from one network is routed through an encrypted tunnel to another network.
Tunneling is the process of establishing and maintaining a logical network connection (usually referred to as a “virtual” connection) between two physically separate networks. A VPN tunnel encrypts your data traffic, providing a secure connection between your device and the VPN server. Once your data reaches the VPN server, it decrypts the data and forwards it on to its destination.

SSH, which stands for Secure Shell, is a widely used network protocol that provides a secure and encrypted way to access and communicate with remote systems over an unsecured network. It allows users to securely log into and control remote servers or devices, transfer files, and execute commands remotely. SSH is a fundamental tool for system administrators, developers, and anyone who needs secure remote access to computers or network devices.
The primary purpose of SSH is to establish a secure encrypted connection between a client and a server, ensuring that data transmitted between them cannot be intercepted or tampered with by malicious actors. It replaces the less secure and plaintext-based protocols like Telnet and rlogin, which transmit data in clear text, making them vulnerable to eavesdropping and unauthorized access.
SSH provides three essential functionalities:
- Secure Remote Login: SSH enables users to log into remote servers securely, even over an untrusted network such as the internet. It uses strong encryption algorithms to protect login credentials, preventing unauthorized users from intercepting passwords or other sensitive information.
- Secure File Transfer: SSH includes utilities like SCP (Secure Copy) and SFTP (SSH File Transfer Protocol) that allow users to securely transfer files between local and remote systems. These file transfer protocols use the SSH encryption and authentication mechanisms, ensuring the confidentiality and integrity of the transferred files.
- Secure Remote Command Execution: SSH allows users to execute commands on remote systems securely. This capability is especially useful for system administrators who need to manage and administer remote servers without physically accessing them. Users can run commands on the remote server as if they were executing them locally.
SSH works based on a client-server architecture. The SSH client initiates a connection request to the SSH server. Upon successful authentication, an encrypted session is established between the client and server. This session provides a secure channel through which data can be transmitted.
The security of SSH is achieved through several key components:
- Encryption: SSH uses strong encryption algorithms to protect the confidentiality and integrity of data during transit. It encrypts all communication between the client and server, including login credentials, commands, and transferred files.
- Authentication: SSH supports various authentication methods, such as passwords, public-key cryptography, and multi-factor authentication. These mechanisms ensure that only authorized users can access the remote system.
- Key Exchange: SSH utilizes a key exchange algorithm to establish a secure connection between the client and server. This process involves generating a session key used for encryption and integrity checks during the session.
- Port Forwarding: SSH allows users to create secure tunnels between local and remote systems, forwarding network traffic through the encrypted SSH connection. This feature enables users to access services on remote servers as if they were running on the local machine, enhancing security for remote access to sensitive applications.
SSH has become the de facto standard for secure remote access and administration in the IT industry. It is supported on various operating systems and has robust implementations, such as OpenSSH, which is widely used on Linux and Unix-like systems. Additionally, many software applications and development tools utilize SSH for secure file transfers and remote command execution.
HOW TO USE AND CONFIGURE SSH IN WINDOWS ?
To use and configure SSH in Windows, you can follow these steps:
Step 1: Install an SSH Client:
- Windows does not come with a built-in SSH client, so you need to install one. One popular option is PuTTY, a free and lightweight SSH client. Download PuTTY from the official website (https://www.putty.org/) and run the installer.
Step 2: Generate SSH Keys (Optional):
- Generating SSH keys adds an extra layer of security to your SSH connections. While it’s not mandatory, it is highly recommended. PuTTYgen, which comes bundled with PuTTY, can be used to generate SSH key pairs.
- Launch PuTTYgen.
- Choose the desired key type (RSA or DSA).
- Click “Generate” to create the key pair.
- Set a passphrase to protect your private key (optional, but recommended).
- Save both the public and private keys to a secure location.
Step 3: Configure SSH Connection:
- Launch PuTTY, and you will see the PuTTY Configuration window.
- In the “Host Name (or IP address)” field, enter the IP address or hostname of the remote server you want to connect to.
- Set the connection type to “SSH”.
- In the “Port” field, enter the SSH port number (usually 22).
- Under the “Connection” section, expand the “SSH” category.
- If you generated SSH keys, click on “Auth” and browse to the private key file you saved earlier.
- Optionally, you can configure other settings like terminal appearance, proxy, etc.
- Click “Open” to initiate the SSH connection.
Step 4: Connect and Authenticate:
- If this is your first time connecting to the remote server, PuTTY will display a security warning. Click “Yes” to continue.
- PuTTY will open a terminal window and prompt you for your username. Enter your username and press “Enter”.
- Depending on the server configuration, you will be prompted for a password or passphrase. Enter the required authentication information and press “Enter”.
- If the credentials are correct, you will be successfully logged into the remote server.
Once connected, you can use the PuTTY terminal to execute commands, transfer files using SCP or SFTP, and perform other SSH-related operations.
Note: If you want to use the Windows Command Prompt (CMD) or PowerShell as an SSH client, you can install a tool called “OpenSSH for Windows” (available as an optional feature in Windows 10). Once installed, you can use the “ssh” command in CMD or PowerShell to establish SSH connections.
Remember to adhere to proper security practices, such as using strong passwords, regularly updating software, and applying appropriate firewall settings, to ensure the security of your SSH connections.
HOW TO USE AND CONFIGURE SSH IN KALI LINUX ?
SSH is pre-installed in Kali Linux, a security-focused Linux distribution. To use and configure SSH in Kali Linux, follow these steps:
Step 1: Start SSH Service:
- Open a terminal in Kali Linux.
- Run the following command to start the SSH service:
sudo service ssh start
- If the service is already running, you will see a message indicating that it is starting.
Step 2: Configure SSH:
- By default, SSH should be properly configured in Kali Linux. However, you can modify the configuration if needed.
- To configure SSH, open the SSH server configuration file in a text editor:
sudo nano /etc/ssh/sshd_config
- Make any necessary changes to the configuration file. Common configurations include changing the SSH port, enabling or disabling certain authentication methods, and modifying access controls.
- Save the changes and exit the text editor.
Step 3: Allow SSH through the Firewall:
- If you have a firewall enabled on your Kali Linux system, you need to allow SSH traffic through it.
- Run the following command to allow SSH traffic in the firewall:
sudo ufw allow ssh
Step 4: Connect to Kali Linux via SSH:
- To connect to your Kali Linux machine via SSH from another computer, you need an SSH client.
- On the remote computer, open an SSH client application (e.g., PuTTY on Windows, OpenSSH on macOS or Linux).
- In the SSH client, enter the IP address or hostname of your Kali Linux machine.
- Specify the SSH port if you modified it in the SSH server configuration (default is 22).
- Enter the username and password of your Kali Linux user account when prompted.
- If the credentials are correct, you will establish an SSH connection to your Kali Linux machine.
Remember to follow security best practices, such as using strong passwords, disabling root login (preferably use sudo), and using key-based authentication instead of passwords when possible, to enhance the security of your SSH connections.

Mid-infrared (mid-IR) lasers
Compact, high-efficiency, mid-IR laser sources in the ~3-5 µm range are exciting for a number of applications including industrial gas monitoring, chemical/bio sensors, IR countermeasures, and communications systems. Current approaches to compact mid-IR sources include type-II “W” structures, quantum cascade lasers (QCLs), and type-I quantum wells on GaSb. Type-I GaInAsSb/AlGaAsSb active regions grown on GaSb offer significant advantages over other approaches, including room temperature operation, low threshold current density, high output power, and temperature stable operation. Specifically, they feature more straightforward device design and growth than QCLs and substantially higher gain and operating temperatures than W structures.
Low-noise III-V avalanche photodetectors
Avalanche photodetectors exhibit built-in gain and can operate at high bandwidths, making them critical in fiber-optic systems, 3-D laser radar (LIDAR), sensing systems, etc. We have demonstrated the highest gain, low noise, InAs avalanche photodetectors, the first working staircase avalanche photodetector, the first quaternary alloy exhibiting low excess noise, and the first low-noise III-V avalanche photodetector operating at the standard wavelength of fiber optic communications (1.55 μm).
Epitaxial plasmonic materials
We have been actively studying the introduction of plasmonic functionality into the heart of modern photonic devices, which necessitates plasmonic materials that can be epitaxially-integrated with III-V optically-active materials (e.g. quantum wells and dots). We have achieved record high plasma frequencies for InAs:Si, the first demonstration of plasmonic response from rare earth monopnictides (e.g. ErAs), and the first demonstration of demonstration of compositional tuning of plasmonic properties (e.g. LaLuGdAs).
Metal/semiconductor nanocomposites for terahertz (THz) generation
There is currently a great need for systems to detect and identify chemical and biological agents. The 0.3-3 THz frequency range is a critical regime for such applications because of the many vibrational and rotational lines of key chemical/biological agents. The needs of such systems: high sensitivity/specificity, compact, rugged, portable, and power efficient place significant demands upon the THz sources. They must operate at room temperature and be widely tunable with narrow linewidth and high output power, electrically-driven, power-efficient, compact/rugged, and (preferably) operate cw. This requires sources that are far superior to those currently available. We are investigating new epitaxial metal/semiconductor nanocomposites to dramatically increase the performance of photomixer THz sources.
(Practical) silicon-based lasers
It has long been recognized that the integration of silicon-based electronics with photonics could be extremely powerful. This field has blossomed in recent years with the realization that on-chip interconnects are fast becoming a substantial source of power dissipation and delay. This coincides with historical progression of light as the preferred data transmitting medium on progressively smaller and smaller length scales: from ocean-to-ocean, city-to-city, ..., board-to-board, chip-to-chip, and eventually on-chip. Virtually all of the necessary optical components are in place for silicon-based optoelectronics, with the key exception being a monolithic, electrically-pumped, CMOS-compatible laser. The ultimate length scales and applications that optics will penetrate will depend on whether the silicon-laser problem can be solved, as well as its ultimate performance.
III-V transistors on silicon
The ITRS roadmap predicts serious difficulties in the coming years with simply scaling silicon CMOS. As a result, the silicon MOSFET is being virtually reinvented; high-k dielectrics are replacing SiO2 as the preferred oxide in MOSFETs. As a result, the arguments for a Si or SiGe channel become far less compelling. We are collaborating with Professors Sanjay Banerjee and Jack Lee to develop high-performance III-V MOSFETs.
Applying wireless communications approaches to optical fibers
In collaboration with Professor Sriram Vishwanath, we are studying the use of wireless signaling techniques (e.g. MIMO) to communications over conventional multimode optical fibers. Using these techniques, we have exceeded the bandwidth-length product of a conventional fiber by >15x, using only off-the-shelf-components.

Worker Safety Management System Notice Master
By interlocking with safety sensors and measurement equipment, the danger signal of safety sensors and the alarm output of measurement equipment are transmitted wirelessly, and alarms are sent directly to the wristwatch-type receiver worn by operators and workers, or to the helmet-type receiver. It is a system that can communicate.
The wristwatch type receiver can be linked with various sensors such as "sound", "vibration", and "text" to notify the alarm, and the helmet type receiver can notify the alarm by "vibration" and "sound". Therefore, it is possible to use it according to the needs of the site and improve the safety of workers.

Sense ultrasonic amplitude changes and guard against unplanned downtime
Sense ultrasonic amplitude changes and guard against unplanned downtime!
The Ultra-Trak 750 shows you early warning signs of:
- Mechanical failure
- Valve leakage
- Flow disruption
- Arcing by detecting changes of ultrasonic amplitude
How it Works:
The Ultra-Trak senses high frequency emissions produced by operating equipment. A baseline threshold can be set within a wide dynamic range of 120 decibels. Once set the Ultra-Trak then monitors changes of ultrasonic amplitude within a range of 40 decibels. The Ultra-Trak can be connected with other devices to provide alarms or for tracking potential problems over time. In some instances the Ultra-Trak can be used for sound level increases, such as to warn of onset of valve leakage or bearing failure. Amplitude fall-off can be used to signal line flow disruption or alarm of machine shutdown.
Ultra-Trak is ready to guard against unplanned downtime and product loss the minute it is installed. Ultra-Trak passively monitors ultrasounds produced by operating equipment. It can be readily connected to alarms or recorders for data logging, thanks to its 4-20 mA current output, coupled with a pure demodulated output.
Housed in stainless steel, the rugged Ultra-Trak 750 is water resistant and dust proof, which means it can be externally mounted in some of the most challenging environments. Couple this with an extraordinarily wide dynamic range of 120 dB and sensitivity adjustment; this sensor is ready to meet your most demanding sensing needs.
UE Ultra-Trak 750 Features:
- Demodulated Output for Analysis
- Dynamic Range: 120 dB
- Sensing Range 40 dB: Once the sound level is set, there is a 40 dB monitoring range.
- Peak Frequency Response: 40 kHz
- Outputs for External Data logging or Sound Recording.

Product design at ARG starts with a comprehensive system functional specifications document.
Once the specifications document has been reviewed and approved, the electronics and mechanical portions of the design proceed in parallel with a very tight linkage between the two. At the same time, components selected for the project are carefully evaluated for any supply chain issues .
Prototypes – boards and mechanical components – are manufactured next. You can use your existing manufacturing shops or ARG can source the prototype fabrication for you.
Firmware and software development are the next steps (after receipt of the prototypes) followed by testing.
In some cases, testing reveals the necessity for a few design changes. If so, the process is repeated. If testing is successful, the final step is the documentation needed for manufacturing.

This paper presents a fully implantable brain machine interface based on a new CMOS system-on-a-chip (SOC) including a low-power multi-channel current-reuse analog front-end (AFE), a multi-band wireless transceiver and a power management unit retrieving power from a 13.56 MHz carrier through a new 5-coil inductive link. In addition to this SOC, the proposed interface includes a low-power microcontroller, a wideband antenna and a double-sided power recovery coil. All components are bonded on a thin flexible printed circuit board. The AFE uses a new current-reuse circuit topology based on a current-mirror opamp which is scalable to very large number of recording channels, thanks to its small implementation area and its low-power consumption. It includes a low-noise amplifier (LNA) and a programmable gain amplifier (PGA) presenting tree selectable gains of 35 dB, 43.1 dB and 49.5 dB. The SOC is fabricated in a CMOS 180-nm process and has a size of 1.3 mm × 1.8 mm. The AFE has a low-power consumption of 9 µW (4.5 µw for LNA and 4.5 µw for PGA) per channel, for an input referred noise of 3.2 µV. A 5-coil wireless power link is utilized with an efficiency of 28% and a maximum power delivered to the load of 81 mW through a 1 cm2 flexible coil. The ultra wideband edge combining BPSK transmitter reaches a maximum data rate of 800 Mbps at 6.7 pJ/bit, and the 2.4-GHz OOK receiver reaches a maximum data rate of 100 Mbps. The whole system consumes 12.3 mW and weights 0.163 g. Finally, we present biological results obtained in-vivo from the cortex of an anesthetized mouse.

Engineers in the US have invented an inexpensive printed sensor that can monitor the tread of car tyres in real time, warning drivers when the rubber meeting the road has grown dangerously thin.
“With all of the technology and sensors that are in today’s cars, it’s kind of crazy to think that there’s almost no data being gathered from the only part of the vehicle that is actually touching the road,” said Aaron Franklin, Associate Professor at Duke University in Durham, North Carolina.
“Our tyre tread sensor is the perfect marriage between high-end technology and a simple solution,” Franklin said.
In collaboration with Fetch Automotive Design Group, the researchers demonstrated a design using metallic carbon nanotubes (tiny cylinders of carbon atoms just one-billionth of a meter in diameter) that can track millimetre-scale changes in tread depth with 99 per cent accuracy.
The sensor design was detailed in IEEE Sensors Journal.
The technology relies on the well understood mechanics of how electric fields interact with metallic conductors.
The core of the sensor is formed by placing two small, electrically conductive electrodes very close to each other.
By applying an oscillating electrical voltage to one and grounding the other, an electric field forms between the electrodes.
While most of this electric field passes directly between the two electrodes, some of the field arcs between them.
When a material is placed on top of the electrodes, it interferes with this so-called “fringing field.”
By measuring this interference through the electrical response of the grounded electrode, it is possible to determine the thickness of the material covering the sensor, the researchers said.
While the sensor could be made from a variety of materials and methods, the best results were obtained by printing electrodes made of metallic carbon nanotubes on a flexible polyimide film, according to the study.

In this article we will explain the effect of aliasing, why it occurs and what can be done against it. Aliasing can occur whenever a sample rate conversion or sampling of an analog signal is performed. Great care needs to be taken to inhibit aliasing, as otherwise the resulting signal can be severely degraded.
To motivate this, let us listen to the effect of aliasing for three different kinds of signals. We take an original audio signal and perform a downsampling operation, for example to save bandwidth. Naturally, higher frequencies in the signal cannot be represented accurately with a too low sampling rate, so the downsampled audio does not sound as "bright" as the original. Despite, the effect of aliasing even impedes the audio quality. For each signal, first the original signal is presented, followed by a downsampled version that contains aliasing. Finally, the downsampled audio that has been sent through an anti-aliasing filter to prevent aliasing is provided.
A speech signal (taken from LibriVox). Here, aliasing manifests itself as some extra noise, especially around characters like 's' and 'z'.

IMSI Catcher and Selective jammer is an eavesdropping device used to intercept mobile phone’s traffic and tracking location data and mobile phone user. IMSI Catcher and Selective jammer masquerades as a mobile phone tower deviating phones within a certain radius into connecting to the device. Mentari Setia Sdn Bhd are the supplier of the IMSI Catcher device in Malaysia.
IMSI Catcher and Selective jammer use in Law enforcement
Law enforcement agencies in many multiple countries used the device to track cell phones in order to gather information or/and eavesdropping in on conversations. Some military intelligence branch used the device to intercept terrorist’s phone calls and found out the exact locations of their target.
What Does a Cell Phone Jammer Do?
The main purpose of a cell phone jammer is to stop all cell phones in the location from being able to communicate with the cell phone tower. Although the concept is simple, the methods used to achieve this are quite complicated.
Cell phone jammers work by targeting frequencies that cell phones typically use to communicate. Cell phones use different frequencies because they send and receive signals simultaneously at all times. Cell phones can also switch between frequencies to try to find the best channel for communication.
Less sophisticated cell phone jammers attempt to block cell phone signals by jamming only one frequency. Often, jamming one frequency that the cell phone uses can trick the device into believing that there is no signal. In turn, the device will not function.
More sophisticated cell phone jammers can block more than one frequency at one time. These jammers can be set to target several different frequencies that the cell phones are using, to stop both sending and receiving data. This method can also help jam signals that cell phones will attempt to switch to for a better connection as well.
More sophisticated devices, therefore, can jam cell phones on multiple networks and cut off all communication of data.
Cell Phone Jammer Uses
When it comes to the government and military, signal jammers are powerful counter tool for counter-terrorism strategies for everything from blocking radio communication to disabling explosives. Stopping criminals and offensive forces from communicating is key to thwarting their plans and ability to gather and strategize.
When it comes to civilians, signal jammers are also very useful.
Civilians that are worried about their privacy see signal jammers as a defensive tactic. Signal jammers can stop cell phones and other devices from communicating with the outside world. This can stop devices like microphones, GPS trackers, and cameras from transmitting data to malicious actors.
If a civilian is bombarded by scammer calls or needs quiet time, a cell phone jammer can stop a cell phone from receiving calls. It can help bring peace and allow you to focus on your life rather than constant phone calls.
Employers can use cell phone jammers on small and large scales. They can use them during meetings to stop employees from being distracted. Or, they can stop employees from sending and receiving communication with their cell phones during work hours.
At schools, cell phones are a major distraction. Often students will use them to cheat on tests or carry on private conversations that distract from learning. Cell phone jammers can be used by schools to stop students from using their cell phones during school hours.
Other places that rely on the quiet, such as libraries and theatres, might use cell phone jammers to stop visitors’ phones from ringing. It can also discourage people from using their phones altogether during their visit.
How it works
The IMSI Catcher tricked the targeted cell phone into believing they are the closest cell towers. Once the cell phone connects to the IMSI Catchers, the unit will act as a middle device between the cell phone and the real tower.
Mobile phones work by searching for the closest cell’s towers. The IMSI Catcher will tracked the targeted mobile phone and tricked it into identifying it as the closest cell towers. After successfully connecting to the cell phone, the IMSI Catcher device will become the middle devices between the cell phone and the tower.
Are smartphones immune to the IMSI Catcher device?
There is a belief among iPhone users that their phones are encrypted and thus they are safe from IMSI catchers. This is simply not true. Both Android and iOS devices can be tracked with ease using IMSI catchers.
