Indoor positioning PLC systems
Power line communication (PLC) systems are becoming a mature field with an increasing scientific and industrial interest. PLC provides broadband connection by using the existing mains, easing the connection of different devices. The medium access techniques recommended in the standards of PLC are OFDM, with and without a window in the transmitter, and Wavelet OFDM, based on a cosine modulated filter bank.
Indoor positioning systems (IPS) provide a position fix for devices inside different buildings. Their use and applications have increasing scopes ranging from context data assisting/forwarding in museums, object tracking, marketing, etc. A common approach for IPS, is to deploy radio-frequency beacons inside the building and have a tag that collects the signals from those beacons to obtain the position fix.
Although the PLC signal that travels on the cooper cables is of low power and does not irradiate strongly, some trace of it is still available in the air. Therefore, our working proposal is to investigate how and at which extent PLC signal could be used for indoor positioning. As a first goal, one will investigate the attainable accuracy of using PLC signals for IPS. Secondly, we will propose how to employ the PLC standard framing structure for positioning purposes. This will encompass both using devices that upconvert and transmit the PLC signal so that the positioning data that should be conveyed by the beacon signal comes directly from the PLC system. Thirdly, one will investigate the feasibility of doing the localization disregarding the mentioned device.
For achieving the above goals, specific communication channel models, machine learning, pattern recognition and signal processing techniques are necessary. Therefore, investigation effort is necessary to understand, propose and develop the relevant methods, algorithms and techniques that may impulse the envisioned scenario.

The recent trend of military is to combined Internet of Things (IoT) knowledge to their field for enhancing the impact in battlefield. That¡¯s why Internet of battlefield (IoBT) is our concern. This paper discusses how Fog Radio Access Network(F-RAN) can provide support for local computing in Industrial IoT and IOBT. F-RAN can play a vital role because of IoT devices are becoming very popular and the fifth generation (5G) communication is also an emerging issue with ultra low latency, energy consumption, bandwidth efficiency and wide range of coverage area. To overcome the disadvantages of cloud radio access networks (C-RAN) F-RAN can be introduced where a large number of F-RAN nodes can take part in joint distributed computing and content sharing scheme. The F-RAN in IOBT is very effective for enhancing the computing ability with fog computing and edge computing at the edge. To overcome the difficulties of fog computing in IoBT this paper illustrates some challenging issues and solutions to improve battlefield efficiency.

In multihop wavelength division multiplexing systems, a connection between two communication nodes consists of one or more lightpaths. A wavelength conversion is required at the joint of two lightpaths if they use different wavelengths. Wavelength conversion incurs significant delay in data transmission, and overhead in connection setup. This paper discusses the problem of assigning wavelengths to a set of lightpaths such that the overall number of wavelength conversions in the system is minimized. The problem is formulated as the maximum clique-partition problem and an approximation algorithm is proposed to solve it. We also quantatively analyze the relationship between the number of wavelengths and the number of conversions required in the system. Extensive simulations have been conducted to demonstrate the reduction of wavelength conversions by employing the proposed algorithm.

Unsteady Optical and Thermal Behaviour of Cross Compound Parabolic Concentrator with Solar Cell
Reason for embargo
Under indefinite embargo – no publisher permission.
In reality, a solar panel with concentrator is subject to variable sunlight radiation, wind speed and environmental air temperature in a day, accordingly the solar output power is changed in a wide range of 2W-13W, causing a degraded electric performance [1-3]. Thus it is necessary to characterise optical and thermal behaviour of a crossed compound parabolic concentrator (CCPC) with solar cell in its design stage to optimise its configuration. Presently, the CCPC optical and thermal performance characterisation is usually based on steady-state physics models, see [4-8], for example, thus ignored unsteady variation of air flow and heat transfer in concentrator. In this contribution, we investigate the optical and thermal performance of an isolated CCPC with solar cell from the solar panel in [6,7] by means of ANSYS CFX. The CCPC with solar cell is subject to a variable sunlight radiation intensity, wind speed and air temperature from 6am to 17pm a day which were measured in  on 20th March 2009.

Actually 587 is quite useful: you can set it as an accept STARTTLS/AUTH
only port for all your remote users who would otherwise get their
outbound 25 traffic blocked.
I've never liked the fact that MUA to MTA communication used the same
port as MTA to MTA communication. It just made configuration and
filtering that much harder. 587 is poised to fix this.

In this paper, we introduce an optimal bias voltage searching strategy and maintaining method in BOTDA system based on dual sideband modulation. The system utilizes both up shifted and down shifted continuous wave light to generate Brillouin scattering light, while using the amplified pulsed light to boost the signal by stimulated Brillouin scatting effect. In order to obtain a clean Brillouin shifted curve along the fiber under test, the probe light must be in good signal to noise ratio. In addition, the intensity of shifted light should be stable as well. Therefore, we propose a novel control method of frequency shift in sideband modulation of a BOTDA system, which keeps the first order frequency-shifted light at its maximum signal to noise ratio and minimum light intensity fluctuation. We also implement static experiments to verify our proposed scheme. Strain/temperature tests were taken out to evaluate the performance of the BOTDA. Results showed that the resolution of BOTDA system could reach 13με/0.65°C at 50 km fiber cable with spatial resolution of 0.5m.

This application claims the priority of Korean Patent Application No. 2004-45296, filed on Jun. 18, 2004, in the Korean Intellectual Property Office, the disclosure of which is incorporated herein in its entirety by reference.
1. Field of the Invention
The present invention relates in general to a controlling method of an optical recording apparatus, and more particularly, to an optical recording apparatus and a controlling method of an optical recording apparatus, in which although a data recording operation on an optical recording medium may be temporarily stopped or paused by a user, the recording operation is automatically resumed exactly at a recording resume preset time.
2. Description of the Related Art
An optical recording apparatus is a device for recording data on an optical disk using an optical disk driver. Typically, data is recorded on the optical disk in stream format, so that users are provided with images of the high quality and sounds.
In general, the function keys on the key input unit 110 include a play key 110 a to reproduce the data, a record key 110 b to perform data recording, a stop key 110 c to stop the process currently underway, a pause key 110 d to stop, temporarily, the process currently underway, an open/close key 110 e to open or close the tray 130, a rewind key 110 f, and a fast forward key 110 g.
The pause key 110 d is used to apply a signal requesting temporary stop of data recording to the optical recording apparatus, such that a data recording operation currently underway is temporarily stopped. In contrast, the stop key 110 c is used to stop the recording operation completely.
When the user operates the record key 110 b on the front panel 100, a record request signal is applied to the optical recording apparatus, and as a result, data from external equipment is recorded on the optical disk. At this time, if the user needs to go somewhere for a while or the external equipment provides unwanted data, the user operates the pause key 110 d to pause the data recording operation.
Once the data recording operation is paused by the operation of the pause key 110 d, the optical recording apparatus is kept in pause state and does not resume the recording operation until the user applies a recording resume request signal to the optical recording apparatus by operating the record key 110 b.
However, if the user does not return within time to resume the data recording operation and leaves the optical recording apparatus in pause state, or if the user forgets what he was doing and fails to resume the recording within a predetermined time, the user often loses data he wanted to record.
An aspect of the present invention is to solve at least the above problems and/or disadvantages and to provide at least the advantages described below. Accordingly, an aspect of the present invention is to provide an optical recording apparatus in which a user presets a recording resume time so that the data recording operation is automatically resumed at the recording resume time even after a temporary stop of the recording operation on the recording medium has been made by the user, and a controlling method thereof.
To achieve the above-described aspects of the present invention, a controlling method of an optical recording apparatus to record data in a recording medium, the method including performing a recording operation to record the data in the recording medium; applying a pause request signal to stop, temporarily, the recording operation; determining whether to set a record resume time; and if the record resume time is set while the recording operation is in pause, temporarily stopping the recording operation, and then resuming the recording operation at the record resume time.
If the user declines to set the record resume time, maintaining the pause state until a record request signal to resume the recording operation is applied.
In an exemplary embodiment, if a specific amount of time for the recording operation is allocated, the recording operation is performed for the allocated amount of time.
In an exemplary embodiment, the record resume time is set within a remaining time of the allocated amount of time.
Another aspect of the invention provides an optical recording apparatus to record data provided from an external equipment in a recording medium, the apparatus including: a pickup to record the data in the recording medium; a servo driver to drive the pickup; a key input unit to apply at least one request signal; and a controller to control the servo driver, wherein if a record resume time is input following the application of a pause request signal from the key input unit to pause the recording operation, the controller controls the servo driver to stop the pickup temporarily, and if the record resume time occurs, the controller controls the servo driver to drive the pickup.
The apparatus further includes a display to display designated information under the control of the controller, and if the pause request signal for temporarily stopping the recording operation is applied, the controller controls the display to show a message asking a user whether to set the record resume time.
In an exemplary embodiment, if the user declines to set the record resume time, the controller controls the servo driver to ensure that the pickup is maintained in a pause state until a record request signal is applied from the key input unit.
In an exemplary embodiment, the key input unit is a remote controller to send an infrared signal in correspondence with the request signal.
Additional aspects and/or advantages of the invention will be set forth in part in the description which follows and, in part, will be obvious from the description, or may be learned by practice of the invention.
The above aspects and/or features of the present invention will be more apparent by describing certain embodiments of the present invention with reference to the accompanying drawings, in which:
Reference will now be made in detail to the embodiments of the present invention, examples of which are illustrated in the accompanying drawings, wherein like reference numerals refer to the like elements throughout. The embodiments are described below to explain the present invention by referring to the figures.
The matters defined in the description such as a detailed construction and elements are provided to assist in a comprehensive understanding of the invention. Thus, it is apparent that the present invention may be carried out without those defined matters. Also, well-known functions or constructions are not described in detail since they would obscure the invention in unnecessary detail.
As illustrated in
The DSP 240 converts data input to the optical recording apparatus 200 into digital data, and performs on the converted data a signal processing operation such as error correction to convert the data into a recording format. The CODEC 230 encodes the data converted into the recording format by the DSP 240, and decodes the encoded data. The spindle motor 270 rotates a loaded optical disk 200 a. The pickup 210 records a signal in the optical disk 200 a, or reads a recorded signal therefrom. The RF signal processor 220 filters and shapes the signal detected by the pickup 210 into a binary signal, and outputs it. The servo driver 250 controls the operations of the pickup 210 and the spindle motor 270.
The user interface 280 applies to the controller 250 a key operation signal applied by the user through the key input unit 110. As for the key input unit, the key input unit 110 of
There are certain types of key operation signals applied to the controller 250 through function keys shown in
If a record resume time is input after the pause request signal is applied from the key input unit 110 through the user interface 280, the controller 250 controls the servo driver 250 and stops the pickup 210 temporarily. As a result, the data recording operation currently underway stops temporarily.
When the record resume time is provided from the user interface 280 and the time is reached, the controller 250 controls the servo driver 250 to drive the pickup 210 again. In this manner, the temporarily stopped data recording operation is resumed.
If the pause request signal is applied, but the record resume time is not input from the user interface 280, the controller 250 controls the servo driver 260 and ensures that the pickup 210 is maintained in pause state until the record request signal is applied from the user interface 280.
Using a generally known method, the user loads the optical disk 200 a to the optical recording apparatus 200 connected to a designated image source, and operates the record key 110 b. Then, the record request signal is transferred to the controller 250 from the user interface 280, and the controller 250 controls the servo driver 260 to drive the spindle motor 270. In this way, a recording data provided from the image source is recorded in the optical disk 200 a (S200).
While the optical disk 200 a is recording the data, if the user operates the pause key 110 d, the pause request signal is applied from the user interface 280, and the controller 250 displays on the display 120 a message asking the user whether to set the record resume time (S210, S220).
If the record resume time is input from the user interface 280, the controller 250 controls the servo driver 260 to stop the spindle motor 270 (S230, S240) temporarily. The record resume time is recorded so as to allow the recording of the data to be resumed.
If the record resume time input from the user interface 280 has occurred while the data recording operation is being temporarily stopped, the controller 250 controls the servo driver 260 to ensure that the spindle motor 270 starts driving again, and the temporarily stopped recording operation may be resumed (S250, S260).
In operation 220, in the case that the user declines to set the record resume time, that is, if the user gives ‘No’ for an answer to the message provided to the display 120 by the controller 250, the message asking whether the user wants to set the record resume time, the controller 250 controls the servo driver 260 to stop the spindle motor 270 temporarily, thus temporarily stopping the data recording operation (S220, S240).
If the recording operation is temporarily stopped without the record resume time being preset, the controller 250 is maintained in pause state until the record request signal is applied from the user interface 280.
After operation 250 and if no record resume time is recorded, if the user operates the record key 110 b, and therefore the record request signal is applied from the user interface 280, the controller 250 controls the servo driver 260 to drive the spindle motor 270, thus resuming the temporarily stopped recording operation (S280).
As may be appreciated from the above description of the an optical recording apparatus and the method to control the same, according to an embodiment of the present invention, when a user wants to stop temporarily during the recording process, the record resume time may be selectively set by the user to resume the recording correctly at a desired time.
While described as used with an optical recording apparatus, it is understood that the present invention may be used with magnetic and/or magneto-optical apparatuses.
While described as a record resume time, it is understood that other, non-time based events may be used to resume, automatically, recording of the data. Thus, accordingly to aspects of the invention, recording may be resumed if an eject button is pressed or if the power button is turned off to ensure that the recording is completed.
Accordingly, although the user may not return within time to resume the data recording operation after leaving the optical recording apparatus in a pause state, or the user forgets to resume the recording within the time to resume the data recording operation, loss of data for recording may be prevented.
The present invention may also be embodied as computer readable instructions on a computer readable recording medium. The computer readable recording medium is any data storage device that may store data which may be thereafter read by a computer system. Examples of the computer readable recording medium include read-only memory (ROM), random-access memory (RAM), CD-ROMs, magnetic tapes, floppy disks, optical data storage devices, and carrier waves (such as data transmission through the Internet).

Call recording software records telephone conversations over PSTN or VoIP in a digital audio file format. Call recording is distinct from call logging and tracking, which record details about the call but not the conversation; however, software may include both recording and logging functionality.
Call recording is becoming increasingly important, with technology changing and working habits becoming more mobile. Addressing mobile recording is now the subject of many financial regulators' recommendations. It is also increasingly important to business continuity planning, especially for pandemic planning.
The actual recording takes place on a recording system with software for the management of calls and security of recordings. Most call recording software applications rely on an analogue signal via either a call recording adapter or a telephony board.
Digital lines cannot be recorded unless the call recording system can capture and decode the proprietary digital signalling, which some modern systems can. Sometimes a method is supplied with a digital private branch exchange (PBX) that can process the proprietary signal (usually a conversion box) before being channeled to a computer for recording. Alternatively a hardware adapter can be used on a telephone handset as the digital signal is converted at that point to analogue.
VoIP Recording is usually restricted to streaming media recorders or software developed by the softphone or IP PBX creator. There are also solutions which use packet capture technology to passively record VoIP phone calls on the LAN.
Hardware is required to make the voice signal available to the computer equipment. Some of today's call recording software is sold as a turn-key solution with hardware.
Direct recording of mobile phone calls requires a hardware adapter connected to the handset. There are many other ways to record mobile phone calls. One approach is to route calls via a new PBX system linked to the recorder. However, such systems are typically expensive to purchase and change the way that calls are made, incurring running costs. Another approach links directly into existing recording systems from a PDA phone. Both of these approaches allow recordings to be timestamped, often required for legal reasons. Recording directly onto mobile devices does provide a legally valid recording in many countries.

More than 120,000 developers have selected the platform as their tool to start building IoT projects
Internet of Things (IoT) solutions firm myDevices has chosen tech show CES 2017 to officially introduce its IoT Ready Program for hardware manufacturers. The programme provides manufacturers with the ability to have their devices seamlessly communicate with any other manufacturer’s device.
“Getting different devices from different manufacturers to ‘talk’ to each other has been the holy grail for IoT,” said Kevin Bromber, CEO of myDevices. “For years the IoT industry has tried to develop a set of unified standards, but we can no longer wait to see if this will happen or continue to get derailed.”
myDevices claims its Cayenne project builder platform enables businesses to rapidly deploy IoT solutions and efficiently manage data. Since its introduction one year ago, more than 120,000 developers have selected the platform as their tool to start building IoT projects.
Most of these projects have been centered on maker solutions using the Raspberry Pi or Arduino. However, today’s announcement includes myDevices’ MQTT API release and full LoRa support which exponentially expands Cayenne’s IoT project building capabilities to enable developers and organisations to use any micro-controller, gateway, sensor, motor and actuator for IoT solutions such as smart buildings, smart farming, smart metering and asset tracking applications.
myDevices has also partnered with LoRa IoT gateways manufacturer Tektelic Communications and OrbiWise, an international solution provider for LPWA IoT networks based on LoRa technology, to showcase at CES a combined end-to-end solution highlighting interoperability and seamless communication between devices.
“With our free IoT Ready Program, developers can mix and match sensors, gateways, and other devices all within one project simply by dragging and dropping from our extensive library of supported devices,” added Bromber. “The use case possibilities are endless and, fortunately, standards are not necessary.”

Security, Privacy, and Safety Concerns.
A major concern for the IoT is the ability to build in adequate security protections. Hackers have already demonstrated the ability to break into video systems, Internet-enabled baby monitors, and other devices. Security researchers have hacked into connected vehicles to demonstrate vulnerabilities and have compromised medical devices to illustrate what types of problems are possible. Data privacy is also paramount. Inadequate security can lead to lost, stolen, or incorrectly used data, including private health and financial data. Connected devices and systems—along with data stored in the cloud—increase the number of vulnerability points. In addition, all of the data generated from sensors, cameras, cellular records, computer logs, and other systems can identify where a person is or was at any given moment. Those data can potentially be used or abused by law enforcement, governments, businesses, and others.
Dangers also exist in the technology itself. Connected 3D printers, which fabricate common items, can empower individuals to bypass laws and “print” illegal weapons and other objects, including drugs and counterfeit goods. Drones, microbots, and nearly invisible nanobots—tiny electronic robots connected in a network—could be used for spying or to commit terrorist attacks. In fact, the U.S. Defense Advanced Research Projects Agency (DARPA) is exploring the use of robot armies that would travel behind enemy lines to carry out military missions. While that could reduce the risks to humans in activities such as defusing bombs or rescuing soldiers in the field, it could also introduce widespread autonomous killing, a highly controversial act that the UN and humanitarian groups have begun to explore.
While the ability to connect physical objects and devices introduces increased efficiencies and, in some cases, cost savings, scaling up those connection points and network creates exponentially greater possibilities. For example, a smart car that connects with a smartphone can already integrate mapping, entertainment, voice commands, and other functions that transform the vehicle into a computer on wheels. However, a network of connected vehicles and infrastructure would allow vehicles not only to avoid crashes while driving but also to “see” around corners and avoid collisions with a bicyclist or a pedestrian. The vehicle could even send the person at risk an instant alert. In addition, sensors in bridges, tunnels, roads, and other infrastructure could indicate when repairs are necessary or when failure is imminent.
Similarly, smart utilities and even smart cities would allow consumers and businesses to utilize energy resources and transportation systems more effectively and at a lower cost than before. Connected devices inside and outside the body could revolutionize the way people monitor health conditions and could allow smart connected devices to release the right amount of medication at the right place and at the right moment. Tiny robotic devices injected into the human body could also detect and fix problems. Although no one can predict the exact course that the technology will take, the IoT is likely to have a profound impact on lives and business in the years ahead.

Address decoding circuit using an OTP
When the size of the memory chip is small, the address decoding circuit for that chip is more complex. An address decoding circuit may need several chips. Since lowering chip count can reduce system cost, one can use an OTP to make several address decoding circuits. A low density OTP memory chip is very inexpensive. Let us use a 1Kx8 OTP to implement an address decoding circuit. The OTP can be programmed in such a way that an output pin gives the same signal for a range of input addresses. Therefore, each output pin can constitute a memory chip enable signal.
For example, in the above figure, the OTP should be programmed in such a way that all addresses on the memory chip 1 have a value of 0 in bit 3 of OTP. All addresses on the memory chip 2 have a value of 0 in bit 7 of OTP.

Up until 2016, provisioning Ethernet networks was a little bit like buying hot dogs and hot dog buns, in that you could not always match up the quantities to get the most efficient configuration. That dramatically changed when the specification for Ethernet FlexE was adopted by the Optical Internetworking Forum as OIF-FLEXE-01.0. The surging demand for higher data rates and more flexible network configuration led to this innovative addition to the Ethernet standard.
FlexE fits in between the MAC and PHY, using MII interface signals. In fact, its operation can be so transparent that it is called a FlexE shim and can be completely transparent to existing physical transport layers. Of course, there is a FlexE ‘aware’ configuration that offers further flexibility for transport hardware that is aware of FlexE.
There are three main operations that FlexE can perform. Using these, a number of significant networking efficiency problems can be solved. The first is bonding, where large data pipes can be connected to multiple lower bandwidth physical lanes. For instance, five 100 GE lanes could be used to support a 500Gbps connection. FlexE can do this without the ~30% loss of efficiency of the link aggregation (LAG) solutions previously used for this purpose. Also, FlexE makes the connection performance deterministic, another advantage over LAG.
The second main capability of FlexE is sub-rating of links. There are instances where a link may operate more efficiently at a lower bandwidth than its interface rating. One example provided by the OIF is where a 300 Gbps link is desired, but its coherent optical physical layer needs four 75 Gbps inputs to send 150 Gbps each over two wavelengths. OIF points out that FlexE allows four 100 GE lanes to carry only 75 Gbps each to suit these needs. The down conversion from 300 Gbps is done in the FlexE shim that feeds the four 100 GE lanes.
The Third major feature of FlexE is channelization, where multiple data streams can be intermixed on one or more FlexE links. This is convenient for cases like 5G where there will be a number of smaller streams that can be interleaved into larger links and be recovered at the endpoint. This delivers a mechanism that allows service providers to offer deterministic Ethernet-oriented pipes of flexible width.
Anyone designing silicon that uses Ethernet will want to incorporate FlexE functionality to ensure optimal and full use of physical layer transport. Along with FlexE, another essential IP for chips that perform communications and networking is forward error correction (FEC). The move to PAM4 with multilevel signaling is exacerbating this need because the higher bandwidth it offers comes with a penalty in the signal to noise ratio, leading to higher bit error rates (BER).
Fortunately, Open-Silicon (a SiFive Company), a leading SOC development solution provider, offers IP that enables their customers to build high performance SOCs that take full advantage of high bandwidth Ethernet, FlexE and FEC for PAM4. The three components of this are Ethernet PCS IP, FlexE IP and multi-channel/multi-rate FEC IP.
The PCS IP supports 64b/66b encoding and decoding and is compatible with a wide range of MII versions. It runs from 10G to 400G. As mentioned above the Open-Silicon FlexE IP supports FlexE aware and unaware interfaces. Their FEC can be used in SerDes that support PAM4 and run up to 400G and can connect up to 32 SerDes lanes. It also can be used for Interlaken as well as Ethernet.
With high speed and high efficiency date transport continuing to be an essential prerequisite for business success, solution providers need to have networking solutions that allow facile data flow from the edge to the cloud to support increasingly complex business models and end-user functionality. Open-Silicon is continuing to maintain a technological edge in this area with the addition of this set of communications related IP.

Historically, very few dollars have been directed toward research and development for fire service needs. Yet, the fire service can benefit greatly from transferring technology developed for the defense and aerospace industries to the fire service. Following are two examples of such technology available from this untapped resource.
THE TETHERED AEROSTAT

It happened suddenly without warning. A tornado watch had just been posted when the tornado swept down on the city. In less than five minutes, the storm cut a quarter-of-a-mile swath of destruction through five miles of sleeping subdivisions before ascending back into the clouds. As fate would have it, the storm also mangled the two communications antennae supporting the city’s 800 MHz radio system. Public safety communications were silenced.
However, the lack of communications was no cause for alarm. As soon as the fire department realized what had happened, a special small trailer was coupled to a fire department vehicle. The trailer was pulled to a predetermined location within the city near the disaster site. After the trailer was uncoupled, a valve was opened. In less than five minutes, a small airship, called an “aerostat,” was fully inflated and ready for deployment above the disaster site. The firefighter attached the antenna and released the tethered aerostat from its boom. When the aerostat reached 300 feet, the firefighter secured the tether, cranked the generator, and switched on the radio repeater. Several minutes after the trailer was positioned, emergency communications were available for police, firefighters, and emergency management personnel.
Using tethered aerostats to facilitate communication is a technology coming of age. In this age of rapidly expanding technology, who would have thought that the Smart Weapons Management Office of the U.S. Army Aviation and Missile Command would be funding, researching, and developing blimps? However, aerostats, both tethered and remotely controlled, can be used to keep a variety of communications platforms aloft for days for considerably less expense than cranking a helicopter or using fixed-wing aircraft. With regard to cost, the more applications identified for the technology, the cheaper it becomes for all users.
Tethered aerostats can serve a variety of communications and sensor needs for the fire service. They can provide aerial scene surveillance at hazardous-materials incidents. They are low maintenance, and there is no rotor wash that might spread contamination. They can be used for aerial observation at a host of important incidents and activities from accident and disaster scenes to large public gatherings. Using standard optics by day and thermal imaging by night, the site commander could observe crews’ movements around a disaster scene. Elevated thermal imaging could be used to spot casualties who may not be readily visible to ground crews.
In America’s new war against terrorists, scene security is becoming of paramount importance. Aerial observation can be used to spot intruders and looters at the scene. Such observations may thwart the success of secondary terrorist incidents, saving the lives of many responders. We are in an unprecedented era. As we face the ravages of fire before us, the greater threat may be approaching us from behind. We need all the help we can muster, and tethered aerostats have much to offer.
In addition to requiring minimum maintenance, tethered aerostats are portable, require little training for users, have a long shelf life, and are relatively low in cost.
Recent events have focused on the need for real-time situational awareness during emergencies. Although many lives were saved as a result of the heroic efforts of responders at the World Trade Center on September 11, 2001, additional lives might have been saved if emergency response officials had access to real-time imagery of the surrounding area immediately after the first attack. Laser communication (LaserCom) has many advantages that can significantly enhance emergency response teams and decision makers’ ability to respond appropriately and quickly during crises, be they the result of terrorist attacks, natural disasters, fires, or major accidents.
Communication lasers use the eye-safe wavelengths of the infrared band and provide the following advantages over radio frequency bands:
•Very large bandwidth. This allows for the simultaneous transmission of voice, data, and images. A throughput of up to 1.2 Gpbs from a 29 lb. LaserCom transceiver has recently been demonstrated. This is 1.2 billion bits per second. Technology that will enable much smaller and lighter transceivers with even greater bandwidth is currently in development. Table 1 gives equivalents of 1.2 Gpbs in information flow.
This bandwidth provides the following capabilities:
- simultaneous voice and data transmission without additional transceivers;
- live audio/video feed from the scene to other responding units, the dispatch center, the command post, or any other location; and
- broadband Internet access from any scene.
•Narrow beam width, unidirectional. This allows secure communications with a low probability of interception. LaserCom signals are extremely difficult to intercept and monitor. Terrorists could monitor radio frequency (RF) communications during an emergency and cause problems for emergency management through jamming, inserting false information, or other actions that would inhibit a timely response. Most importantly, LaserCom will replace current AVL systems and is capable of geo-location and tracking units in the field through the same transceiver.
•Less regulatory hassle. The Federal Communications Commission is finding it increasingly difficult to allocate frequencies. Laser communications do not have this characteristic or regulatory requirement. LaserCom also eliminates the problem with interference.
•Relatively low cost. While LaserCom may be more expensive than many RF systems, the cost of a LaserCom system will be considerably less than typical 800 MHz trunking systems. Also, technological developments (discussed below) will reduce the cost of LaserCom to below that of most RF systems.
•Portability. For a minimal investment, LaserCom communications packages can easily be stored, quickly transported to a scene, and rapidly deployed to support an emergency operation. A small, portable, quickly deployable tethered aerostat could also be used to deploy the portable transceiver where line-of-sight is a problem.
Since lasers are unidirectional and limited to line of sight, you may be wondering how LaserCom can provide all of these advantages. The key is Steered Agile Beams (STAB) technology being developed by the Defense Advanced Research Projects Agency (DARPA). The STAB device can automatically locate and track similar devices while mobile and transmit and receive data, voice, and imagery. Simply described, when a signal is transmitted, multiple laser beams are emitted and steered from the STAB device. When one beam senses the target transceiver, the beam locks on the target and communication occurs. A device that performs functions similar to those of the STAB device already exists, but it is a large, heavy system of gimbaled mirrors that is high in cost and limited in portability. New solid-state/microcomponent technologies such as optical microelectromechanical systems (MEMs), patterned liquid crystals, diffractive microoptics, and photonic crystals are being used to develop small, ultralight, rapidly steered laser beam subsystems of chip-scale size. Line-of-sight limitations could be overcome by a smart system’s relaying signals within a network between STAB devices, including airborne systems, where required, to achieve the required connectivity for elements currently not within the line of sight.
STAB technology developments are revolutionary and will greatly increase LaserCom’s utility and feasibility for multiple applications. This new technology will provide improvements in size, weight, cost, power requirements, simplicity, and performance. LaserCom has the potential to be a very useful complement to RF communications to support fire departments and other emergency response organizations.

VoIP: Advantages? Disadvantages?
We get this question all the time – Would a VoIP system be better for my business than a traditional phone system? Does the size of my company make a difference? Is it as reliable as my traditional phone line? Will I have to change phone numbers? Will the cost be worth the extra features?
Let’s find out…
What are the benefits of VoIP?
VoIP can connect multiple locations and a distributed workforce.
Since the Covid pandemic, many employees are now working from home. VoIP becomes a huge advantage when you have multiple locations, or employees working remotely. Here’s why…
VoIP phone numbers are not hard wired to a specific phone or location like traditional phone lines. This means your employees can make VoIP calls from anywhere, provided they have an internet connection. Another advantage is that you no longer need a separate phone number for each branch or location.
VoIP can scale up or down based on your business needs.
With traditional phone service, every time you add a new employee, expand your office, or move an employee or department to a new location, you have to schedule the phone guy for the installation or rerouting of cables. Sometimes this can take weeks to complete. What if you could add extensions, delete extensions, and move phones within minutes?
Need more lines? All you have to do is upgrade your license key, add the new phones and you are good to go. Scaling down? That’s just as easy. Moving an entire department and want to keep the extensions? Simple. Just pick up the phones and plug them into the computer network port in the new location. One more thing. All of this is a fraction of the cost of modifying your traditional phone lines.
VoIP has Other Cool Features that Traditional Phone Don’t…
- Receive voicemail and fax messages directly to email.
- Instant messaging system allows you to quickly and easily IM an individual or the entire office.
- See if other employees are in, on their phone, or out of the office at a glance.
- Route business calls through the business number to your cell phone, keeping your personal number private.
- Seamlessly set up conference calls whether employees work in the building, from home, or are out in the field.
- Remote phone maintenance save both time and money.
- Video Web-Conferencing built in.
- And more!
VoIP lets you save on long-distance and international phone calls.
Long-distance calls – what’s that? Similar to cell phone providers, calls within the United States are considered local calls and there is no additional charge for calls outside of your area. Similarly, international calls with VoIP are significantly less expensive than traditional landlines.
Cost savings, based on usage, can be as high as 75%.
So… What are the Disadvantages of VoIP?
Like all technology, VoIP phone service has limitations. Here’s what you need to know…
No internet means no VoIP phone service…
This is by far the biggest disadvantage to traditional lines. Your phone system is dependent upon the strength of your broadband connection. AND, a poor internet connection can also affect clarity on your calls.
The solution to this problem is fairly simple.
- Get a reliable internet provider.
- Dedicate an internet network exclusively for VoIP so it is not competing with your other online activity
- Get internet with proper bandwidth.
Not all VoIP providers offer secure transmissions.
Keep in mind, the internet is a public network, so data can be vulnerable during transmission. The same is true of voice data during VoIP calls.
This is why we don’t use the internet without security, or transmit sensitive data without encryption. When selecting a VoIP provider, ask what security measures they have to protect voice data during VoIP calls. Do they offer high-level encryption during transmission?
So… Should You Move Your Business to VoIP? YES!

As wireless technologies become the norm for consumers, they will begin to expect to contact your business for purchases or support via wireless devices, too.
Extending CRM to wireless devices is not as big a stretch as you might imagine. Many commodity-based middleware technologies, such as application servers, already support or will soon support the extension of CRM software components to wireless and mobile devices. At the moment, few packaged mCRM solutions are available; KnowEx Solutions' KnowEx Wireless is one early entrant. Expect more mCRM solutions to hit the market in the next 12 to 24 months.
CRM service providers are also gearing up for the move to wireless. Wireless providers, wireless standards, and tools to create or outsource wireless CRM are coming of age -- although not quickly enough for some of the respondents of our CRM survey. Two-thirds of those polled felt the biggest obstacle to implementing wireless CRM was lack of standards or differences in the technologies supported in various solutions.
But the biggest CRM leap will come with the infusion of peer-to-peer technologies expected in the next few years. Today we think of CRM solutions as access points that are one-dimensional software applications helping companies interact with their customers. Peer-to-peer technologies will create multidimensional interactions: customer-to-company, company-to-customer, and customer-to-customer.
Peer-to-peer technologies will take CRM into an arena where sales and service are supported via componentized application services, and user-driven communities are the order of the day. Imagine a time in the near future when customers not only can interact with your sales and service infrastructure but can also converse with other customers to help one another and exchange information.
The added dimension of customer-to-customer interaction might seem a bit unusual within the current CRM paradigm. But blending peer-to-peer technologies with CRM will be a boon for both companies and consumers. Businesses that can successfully build peer-to-peer customer communities can expect the costs of sales and service to decrease as consumers adopt more self-service habits. Peer-to-peer customer communities also increase the amount of feedback on a company's products and services. Business leaders who can implement strategies to harvest peer-to-peer information exchange will be able to make continuous product and service improvements, thereby increasing customer loyalty.
The next generation of CRM solutions is clearly about giving customers a louder voice and more choices. Companies that don't leverage emerging technologies to this end will be left in the dust.

With the myriads of mobile messaging apps available in the market, it is crucial for developers to stand out by differentiating themselves from the competition. Simple, no-nonsense applications with only one defining feature struggle to appeal to the modern mobile user. In today’s technology-laden world, apps that capture the attention of mainstream audiences need to offer a full array of functions. On the other hand, the demand for constant new updates can clash with applications quest for greater innovation, particular in terms of providing an aesthetically pleasing user interface that does not feel too cluttered.
KakaoTalk’s fun and unique brand image also carries a strong reputation as a leading innovator in the mobile messaging industry. User feedback is the most prioritized aspect for Kakao, and many of its new features were developed specifically to reflect the insight and comments provided by actual users.
Brand-new functions such as the “Do Not Disturb” setting exemplifies KakaoTalk’s customer-centric mindset that also values the importance of privacy. Kakao promotes innovative connectivity, but it also understands the need for people to enjoy the occasional “Me Time.” The “Do Not Disturb” feature offers users the option to disable notifications during a customized time period without worrying about unwanted message alerts.
KakaoTalk, understanding users’ need for message delivery assurance, also offers a neat feature that allows all messages to be delivered without fail, regardless of network conditions. This feature enables KakaoTalk to keep all messages sent by a user to stay afloat in the system and continuously reattempt delivery for a given length of time. So, even in situations where the network connection is unstable or weak, KakaoTalk users can send messages knowing that they will be automatically delivered as soon as the connection is stabilized, even during background mode. Once the message is delivered, the airplane icon disappears and is replaced with the ‘unread count’* number.
The paper plane mode is a great example of Kakao’s core philosophy, which values users and user experience the most. Paper plane mode eliminates any cumbersome need for users to constantly recheck their phones for message delivery confirmation or resend the same message repeatedly, reducing user inconvenience dramatically.
nowing how many people have read your message can be key when taking part in group chats with dozens of people, especially when it involves important announcements. KakaoTalk understands this need and ensures this information is adequately provided through the unread count number. Next to every message sent on KakaoTalk is a countdown number, which begins with the total number of users (excluding message sender) in the chatroom. As others in the chatroom read the message, the number counts down and eventually disappears altogether when everyone has read the particular message. An exclusive feature only available on KakaoTalk, the unread count number makes communication all the more effective while enabling speedier feedback.
Users are bound to be pleasantly surprised almost every time they open KakaoTalk on their mobile devices. There is always a new gem to discover hidden within the settings that will drastically improve their mobile experience. As awesome features like the Do Not Disturb mode, paper airplane mode and the unread countdown illustrate, users can expect continued exciting innovations from KakaoTalk.

ATIS - 0100521
Packet Loss Concealment for Use with ITU-T Recommendation G.711
|Publication Date:||1 March 2005|
This standard describes Packet Loss Concealment algorithms for use in packetized speech transmission systems that use ITU-T Recommendation G.711 to code speech signals. Mechanisms for detecting packet loss are not defined in this standard and will depend on the application.
In 1995, Working Group T1A1.7 (now, PRQC-QOS) published a Technical Report on speech packetization. That Report took note of the importance of packet loss recovery, but made no specific recommendations of how it should be achieved, choosing only to list a number of possible techniques. These included simple techniques such as repeating the previous packet, inserting white noise at the same power level as surrounding packets, or silence substitution.
To provide high-quality speech transmission in packetized systems that use G.711 and in which packet loss may occur, high quality methods for recovering from packet loss are required.

There is no getting around the explosive edge computing growth the IT industry is preparing for in the coming years.
Statista spells it out in eye-popping fashion: It estimates 29 billion IoT devices by 2030.
Edge computing enhances performance by reducing data travel distances, ensuring immediate response times crucial for applications like autonomous vehicles and telemedicine. It promotes cost efficiency by decreasing reliance on centralized data centers, thereby saving on bandwidth and data transmission expenses.
As the demand for IoT devices increases, edge computing offers scalability, preventing centralized system overloads and catering to both small and large businesses. Additionally, local data processing strengthens security by reducing transmission breach risks. Furthermore, it empowers IT providers to customize services to each customer's distinct needs, guaranteeing maximum efficiency and effectiveness.
But behind the numbers may be a story that is just as enlightening to solution providers. In a white paper, Schneider Electric states that edge computing offers new efficiencies to the IT network.
“Internet use is trending towards bandwidth-intensive content and an increasing number of attached ‘things.’ At the same time, mobile telecom networks and data networks are converging into a cloud computing architecture. To support needs today and tomorrow, computing power and storage is being inserted out on the network edge in order to lower data transport time and increase availability. Edge computing brings bandwidth-intensive content and latency-sensitive applications closer to the user or data source,” the white paper reports.
In line with its findings, Schneider Electric has a range of offerings designed to provide solution providers a go-to for customers working to get a handle on their devices.
For example, the EcoStruxure Micro Data Center Solutions are complete IT solutions that combine power, cooling, security and monitoring in an enclosed rack system. Such an approach can keep the edge more organized and in more effective management.
But managing an IT network also demands managing its power consumption and energy efficiency, with sustainability now an imperative. As the edge grows, so will challenges and opportunities for solution providers.

The USB-A port provides 18W of power, while the two USB-C ports may concurrently deliver 140W. The new power bank is based on the GaN 3 technology employed in Anker’s previous GaNPrime chargers.
Bike Price in Nepal 2023 (30+ Brands)
The technology provides increased power production and more efficient AC-DC conversion. A smaller, cooler, and more efficient charging equipment is another benefit of this technology.
A high-tech digital screen conveniently displays charging data on the PowerCore 24K.
It tells you things like how much juice your devices are using out of the power bank and how long it will take to recharge.
Anker recommends only using the screen when absolutely necessary to extend its battery life. Anker also unveiled the Anker 747 GaNPrime, a 150W single-port charger. Unfortunately, Anker’s 747 GaNPrime lacks the latest Power Delivery 3.1 hardware. The Anker 747 can output a maximum of 100W of power at once.
The PowerCore 24K is available for $149.99 on the Anker website or on Amazon. Neither the device charger nor a USB-C cable are included in the packaging. To charge the gadget at the recommended 140W, you’ll need a PD 3.1 charger and a USB-C connection.


Micropelt creates innovative solid state thin film Peltier cooler and thermogenerator devices that build on a scalable semiconductor platform technology. Micropelt products provide extreme power for cooling, cycling, and thermal management on a mm² scale as well as thermal energy harvesting and perpetual power supplies for self-sustained electronic devices. Micropelt solid state thin film devices target the chip spot cooling, energy harvesting, fiber optics, HVAC, and biomedical markets.
Micropelt TE-CORE RF ThermoHarvesting Wireless Sensor System is a complete thermo-powered, self-sufficient wireless sensor node system (WSN). It is based on an energy harvesting module with a power management function, which converts locally available waste heat thermoelectrically to indefinite free electric energy. A wireless sensor module is connected to the TE-CORE RF and is equipped with Texas Instruments (TI) ultra-low power technology (CC2530). A temperature difference of as little as 10ºC between a hot surface and ambient air is enough for the TE-CORE RF to make a temperature measurement and a radio transmission every two seconds. Information about the thermal profile of the heat source, the generated output power, the thermal generator output voltage, the energy storage voltage and battery equivalent are displayed via a USB receiver and PC application software.
The Micropelt TE-CORE ThermoHarvesting Module converts locally available waste heat thermoelectrically to indefinite free electric energy - as long as the heat flows through the thermogenerator (TEG). The integral power conversion and management circuit steps up the gradient-analog' output voltage of the TEG and outputs a fixed voltage (2.4 V by default). The Micropelt TE-CORE ThermoHarvesting Module's harvested energy is being buffered in an extendable capacitor and controlled by a configurable hysteresis.
