Photoluminescence characteristics of porous silicon layers (PSLs) doped with Er or Yb ions are studied. 10μm thick PSLs with a luminescence centered at ∼ 0.8μm are formed by anodic etching of p-type silicon wafers of several Ω-cm resistivity. Rare-earth ions are electrochemically incorporated into PSLs. The Er3+-related luminescence at 1.54μm as well as the Yb3+-related luminescence at 1.0μm is observed at room temperature after annealing at high temperatures (>900°C). The Er-related luminescence is enhanced after annealing in O2, whereas the Yb3+-related luminescence needs oxygen-free atmosphere (H2) for the optical activation. The luminescence decay time of the rare earth ions as well as the host PSLs is measured and the energy transfer mechanism is discussed.


Jauch JOH, JOD and JOE series
These quartz crystal oscillators with HCSL, LVDS or (LV)PECL output are particularly suitable for the interference-suppressed transmission of fast data streams with low interference.
These quartz crystal oscillators are used in extreme high speed data transmission systems. The Jauch JOH, JOD and JOE series oscillators meet the technical requirements of these systems.
The Jauch JOE and JOD series:


HeyClip™ Lockit™ Cable Clips with a Hinged Locking Top are the perfect choice for low-profile applications. Their unique locking design snap-locks the wire saddle for up to a 0.063 panel thickness. Wire Saddles, as they are commonly called, are ideal for routing single wires, fiber optic cable, or bundles and the hinge eases insertion with no danger of crimping.
These Short Cable Clips with an Arrow head Prong are a perfect choice for low-profile applications where cables must have freedom of movement. The arrowhead prong snap-locks the saddle into a 0.138" diameter hole in a 0.063" panel, and allows the saddle to rotate in its mounting hole. This reduces strain on moving cables. Commonly called, "Wire Saddles," these cable clips are ideal for routing wires or fiber optic cable, providing easy top-load insertion and protection from abrasion.
Swivel clips provide complete 360° rotation for infinite and independent mounting possibilities. Each two-component assembly rotates with respect to one another and can accommodate different panel sizes and orientations, eliminating the number of fasteners required for a given application, process or installation. By mixing and matching components, unique solutions can be created: cable tie strap with fir tree, double cable tie strap, cable tie strap with edge clip or tape-on, cable tie strap with c-clip, double c-clip, and more.


Once again the touch sensing products based on Zytronics proprietary Projected Capacitive Technology (PCT) are helping to create a more environmentally sustainable future. The company has confirmed that, through French distribution partner Eurocomposant, its touch sensors have been specified for the user interfaces of IERs Autolib electric car hire stations currently being deployed in Paris and 46 cities of Ile-de-France region.
Trials of Autolib in the French capital began in early October 2011. The intention of this project is to bring about a marked reduction in the citys traffic congestion as well as curbing its pollution levels. The self-service hiring stations work on similar principles to the bicycle rental systems already being used in many urban areas across Europe. Commuters and tourists alike will be able to go their nearest Autolib station and use the automated payment system to gain access to an electric car. Then they can travel to their desired destination, simply dropping the vehicle off at a station nearby, where recharging will take place ready for the next customer.
The user interface in each hire station employs a 12.1-inch format ZYBRID®PCT-based touchscreen made from 6mm thick toughened glass to ensure high levels of impact resistance. The anti-vandal and weather proof rugged touchscreens feature an anti-glare treatment on the front surface to improve readability in direct sunlight and enhance the overall experience. Proven and patented, Zytronics proprietary PCT touch sensing mechanism works on the principle of detecting subtle changes in the modulated charge signal passing through a matrix of micro-fine copper capacitors, embedded into a robust laminated substrate. These capacitors are only 10µm in thickness and so do not impinge on the brightness or clarity of the display. The substrate in which the sensor matrix is held can be made from thick glass or placed behind an additional protective overlay, giving it a high degree of durability and ensuring the touchscreens functional longevity.
Due to the nature of the touch sensing mechanism (requiring proximity to the users finger) and with the active area totally isolated from the external environment, its function is unaffected by the build-up of dirt, scratches, harsh chemicals, presence of liquid on the screen surface, vibration or shock which would cause almost all alternative touchscreen technologies to fail in a short period of time. In practical terms, this means PCT minimises the need for costly repair call outs or ongoing maintenance work. Furthermore, the PCT sensors can be designed to forego a bezel around the perimeter of the screen, something that is mandatory for optical and infrared (IR), and most surface acoustic wave (SAW) touchscreens. As a result PCT enables OEMs to realise modern, attractive and easy to clean, smooth-fronted designs.
As Julien Berger, Sales Director at Eurocomposant, explains, For this application it was necessary to provide a lightweight, highly robust touchscreen solution that was very well suited to installation in an open air environment and could ensure a prolonged operation. This is exactly the sort of setting that Zytronic touch sensors thrive in. They safeguard against the risk of system downtime and allow running costs to be kept to an absolute minimum.
When looking into the touch sensor component of this project, we knew that the sensing solution we would choose had to prove it could cope with the rigours of outdoor deployment, such as extremes of temperature, exposure to wind and rain, even potential vandalism, says Delphine Dahan, Head of Purchasing at IER. Specifying PCT, with its formidable track record in public use and industrial sectors, has given us total assurance in continued high performance regardless of the conditions faced.
Autolib has the potential to change metropolitan transportation irrevocably and we are pleased to have played a part in it, concludes Ian Crosby, Sales & Marketing Director at Zytronic. PCTs drift-free operation and responsiveness in the most demanding environments, its resilience to the various forms of harm that can shorten the lifespan of other touch sensor technologies, plus crucially, its ability to be operated through gloved hands make it an optimal solution for this kind of application.
Zytronic designs and manufactures a range of technologies that optimise the performance of electronic display applications. The companys principle products include award-winning touchscreen technologies, optical filters for enhanced performance and protection, and special filters to minimise electromagnetic emissions. In addition, the company can offer complex shaped glass composites for specialised applications.
Zytronic products are used in electronic displays for information kiosks, web phones, ATMs and gaming machines, as well as by military, computer, telecommunications, medical and lighting OEMs, and are available from its network of worldwide distributors.
The company is headquartered at its state-of-the-art manufacturing facility in Blaydon, Tyne & Wear in the UK. In addition to ISO-approved manufacturing (including ISO 14001:2004), this facility is responsible for ongoing product development in composite technology and is home to Zytronics team of lamination, material science and electronics specialists.

Direct measurement of surface forces due to charging of solids immersed in a nonpolar liquid
journal contributionposted on 2002-05-01, 00:00 authored by W Briscoe, Roger Horn
Direct measurements of a long-range force between charged solid surfaces in a nonpolar liquid are presented for the first time. Measurements were made between mica surfaces in solutions of the anionic surfactant sodium di-2-ethylhexylsulfosuccinate (AOT) at millimolar concentrations in n-decane using a surface force apparatus which has been modified to improve its sensitivity for detecting a weak and long-range force. Modifications include a magnetic drive system, the use of a weak cantilever spring with the apparatus mounted in a vertical configuration, and a detailed consideration of the interference optics to allow accurate measurements of surface separations up to several micrometers. The results show a repulsion that is well fitted by theoretical curves based on a model in which only counterions enter the calculation, in other words, in the absence of a reservoir of ions in the solvent. Fitting the theory to the data allows an estimate of the mica surface charge density of ∼1 mC/m2. A mechanism for surface charging of mica in this solution is proposed, which includes a role for trace amounts of water that are inevitably present and adsorbed surface aggregates of AOT. The relevance of the results to previously observed charge stabilization of colloids in nonaqueous solvents is discussed.

Global Helium Abundance Measurements in Solar Corona

Two U.S. Naval Research Laboratory Space Science Division (SSD) researchers joined an international cadre of scientists July 27 in presenting the results of the first simultaneous global solar corona images of the helium and hydrogen emission that is helping scientists to better understand the space environment.
The paper, “Global Helium Abundance Measurements in the Solar Corona,” was published online in Nature Astronomy and discusses the abundance of helium relative to hydrogen in the solar corona, the outer atmosphere of the sun, seen from earth only during eclipses.
NRL Astrophysicist Dennis Wang, Ph.D., software lead for the HElium Resonance Scattering in the Corona and HEliosphere (HERSCHEL) rocket flight, was responsible for flight and ground software. His NRL colleague, Research Physicist Martin Laming, Ph.D., managed the new model of element abundance fractionation, to include helium.
“Understanding space weather is important for space situational awareness, that is, forecasting and mitigating the effects of solar activity on Navy and Defense Department satellites,” said Laming. “This was one case where instead of explaining the observations after the fact, I was able to see a prediction I had made come true.”
The HERSCHEL sounding rocket, launched Sep. 14, 2009, provided a number of technological advances in space-based remote sensing. Using a concept developed at NRL for a coronagraph functioning in the extreme ultraviolet regime of the electromagnetic spectrum, the helium coronagraph obtained the first images of the solar atmosphere in the region of the solar wind source surface from light resonantly scattered from helium ions.
The leading model for solar wind variability used by the Department of Defense and National Oceanic and Atmospheric Administration space weather forecasters is an NRL SSD product, known as the Wang, Sheely, Arge Model which is based on simple assumptions about the relation of the solar magnetic field structure and the solar wind, and is reasonably successful in predicting the overall variability of the solar wind as it reaches Earth.
Geomagnetic storms impact radio frequency transmission at frequencies refracted, or reflected, by the ionosphere. The Navy uses magnetic sensors in various battlespace applications, which could be disrupted during large geomagnetic storms and Coronal Mass Ejections. These are major reasons why the Navy is interested in disruptions of the Earth’s magnetic field structure in these measurements.
“There is a long chain of work efforts that go from fundamental understanding of the solar atmosphere, to specifying the observables that need to be monitored before we eventually get to reliable Space Weather forecasts,” said Laming. “In the future, service members should anticipate more reliable satellite-based Command, Control, Communications, Computers, Intelligence, Surveillance, and Reconnaissance.”
Laming demonstrates a strong belief in his model’s prediction capability and his understanding of the sun’s corona adding, “I think we all have more confidence in my model and the conclusions one might draw from it.”

Molecular probes reveal deviations from Amontons' law in multi-asperity frictional contacts
Nature Commun. , Volume 9 p. 888:1- 7
Amontons' law defines the friction coefficient as the ratio between friction force and normal force, and assumes that both these forces depend linearly on the real contact area between the two sliding surfaces. However, experimental testing of frictional contact models has proven difficult, because few in situ experiments are able to resolve this real contact area. Here, we present a contact detection method with molecular-level sensitivity. We find that while the friction force is proportional to the real contact area, the real contact area does not increase linearly with normal force. Contact simulations show that this is due to both elastic interactions between asperities on the surface and contact plasticity of the asperities. We reproduce the contact area and fine details of the measured contact geometry by including plastic hardening into the simulations. These new insights will pave the way for a quantitative microscopic understanding of contact mechanics and tribology.

I fully understand the term duty cycle, but I didn't bring it up because of possible confusion by an unfamiliar term. That exercise is left to those who might use those terms to shock and awe (or don't understand the audience). Why would you want to convert from digital to analog (except for CRT)? The kinds of transistors found in LSI and VLSI chips are typically not amplifiers -- they are binary switches. If they need to vary something, they do it using duty cycle. The signal is modulated into sinus radio frequencies. This is an analog process. Computer people might recognize this as something very much like a MODEM only at a much higher frequency. As for your understanding of how LCD works, here's an explanation from the leader in the use of the technology for TVs: http://sharp-world.com/sc/library/lcd_e/s2_1_1e.htm The key is not the twisting, but rather the spinning of the rods to an endwise orientation which allows the light to pass.


In a move that sees the company turn to one of its major rivals for a key technology, Bay Networks Inc has signed with 3Com Corp’s US Robotics unit to enable it to include its x2 56Kbps modem technology in Bay’s 5000 Multi-Service Access Switch (MSX) line. Bay says it was negotiating with USR about the technology before the 3Com acquisition was muted but that the subsequent deal did not change the company’s desire to offer the technology. Bay is the only company aside from USR that has put x2 at the head end, but with USRs position in the consumer market it was clear we had to support it, said Jonathan Sieg, vice president and general manager at Bay’s signal processing group. Bay maintains that taking the technology from 3Com is part of the its recently announced Adaptive Networking strategy that will result in developing open networking industry standards based around IP networks. The deal with USR will see the company offering its x2 technology on its access switch line by September, says Bay. In March, Bay announced that a 56Kbps software upgrade would be available for the 5399 in July, however that was for the rival K56flex technology developed by the rival Lucent Technologies Inc/ Rockwell International Corp K alliance. According to Sieg, that date has now slipped but the K56flex technology will be still be made available and that the two flavors of 56Kbps will be able to run on the same chassis but not share ports. The date for offering K56flex has slipped to sometime in the third quarter – after the x2 upgrade will be ready. Since that announcement both standards have evolved but the USR was a quicker and more solid integration, said Sieg. According to Bay, it has integrated x2 with its Digital Signal Processing (DSP) modem technology and free x2 software downloads for its 5399 Remote Access Concentrator Module for the 5000 MSX platform will be available in September. In addition, 3Com will provide technical specifications and support to Bay Networks. The two companies also say they will participate in x2 interoperability testing. Both K56flex and x2 enable users to download data at speeds up to 56 Kbps.


NB-IoT Gains Early Commercial Traction in the US
The initial commercial deployments on narrowband Internet of Things (NB-IoT) technology are starting in the country. Three major carriers in the country now offer the technology for potential customers.
Over the last two weeks, T-Mobile has launched the first commercial NB-IoT service with Twilio for Sensoneo's trash management system in parts of the US. The carrier has also introduced the first NB-IoT asset tracking system in the US.
T-Mobile initially launched its NB-IoT in July 2018. This was the first nationwide launch in the US.
AT&T introduced its nationwide NB-IoT on April 29 this year. "We have not announced any commercial customers since we launched our NB-IoT network in April," an AT&T spokeswoman tells Light Reading.
AT&T certified its first NB-IoT chip module, the Telit ME910C1, on June 19 2019.
Verizon launched its nationwide NB-IoT network on May 14, 2019. The operator won’'t reveal any details on any "commercial traffic on any of our networks," says a Verizon spokeswoman. "That would be information our competitors would love to have."
Verizon is testing modules from three vendors -- Quectel, SIM-COM and Telit -- on the network.
Sprint hasn't launched a NB-IoT network yet.
NB-IoT is a Low Power Wide Area (LPWA) technology that allows transmissions of up to 100-kbit/s with a battery life of ten years. AT&T, T-Mobile and Verizon are all deploying NB-IoT in the guard bands of LTE in 200KHz channels. A guard band is the unused part of spectrum between radio channels.
Part of the reason NB-IoT is so low-power compared to normal LTE networks is that the narrowband chipsets and modules are designed to transmit small packets of data on the network and then sleep for days, months or even years between data transmissions.

Surveillance aircraft floating high above Maryland
By Bonnie Berkowitz, Todd Lindeman and Gene Thorp, Published: Jan. 22, 2014
Later this year, a pair of unmanned, blimplike aircraft carrying military radar equipment will rise above suburban Baltimore to watch a 340-mile radius of the East Coast.
How they work
Two aircraft, or “aerostats,” will float at an altitude of about 10,000 feet. The pair, called an “orbit,” will work in tandem to detect missiles and other objects within their range. One aerostat detects threats using low-frequency, long-range radar. The other uses higher- frequency radar to track threats and provides targeting data that could be used to intercept them.


I'm looking for an outdoor enclosure that will hold a 1242 AP, can handle the fittings to pass-through the antenna connection (sealed connectors with pigtails so that we can use patch antennas), and has a cooling fan. The fan must be 48v DC powered as I cannot run AC power out to the AP.
I like the Tessco (link below), but it is AC powered, and they won't do a 48v DC fan version for the low quantity we want to buy (we don't need a heater).

In ad hoc wireless networks, wireless terminals can autonomously construct and can maintain the network. They communicate with some neighbor terminals, exchange network information and determine routes for packets on the multi-hop wireless network. Flexible Radio Network (FRN), one of the ad hoc wireless network systems, adopts a proprietary protocol that provides a multiple routes management and a packet retransmission mechanism against packet transmission errors. This system is a commercial product that has been in use in a recent few years. In this paper, we first evaluate the performance through simulations for data-link protocol and routing protocol of the FRN to clarify its basic properties. Furthermore, we propose some techniques that enhance its performance and solve problems on the protocols. We show how they improve the system performance through simulations and analyses.

During its Shape Tech Expo in San Francisco this weekend, AT&T plans to demonstrate how it is using drones to inspect its cell towers from the air. The company is also looking at other future applications that could include using unmanned aerial vehicles (UAVs) to provide improved LTE coverage during crowded events or disasters.
AT&T has been testing various uses for drones over the past year, and the company is already using the technology to inspect cell towers. Among the other uses AT&T is exploring is the deployment of flying COWs (cell on wings) to enhance cell coverage at concerts or other events where large numbers of users can overwhelm the capacity of stationary towers.
The company’s Internet of Things team and its AT&T Foundry innovation lab have also been working with Intel since early this year to explore other uses for drones. The two firms demonstrated some of their tests at the Mobile World Congress in Barcelona in February.
Laying the Foundation for ‘Exciting Applications’
AT&T has reached a new milestone this week by launching the trial phase of its national drone program, John Donovan, the company’s chief strategy officer and group president of technology and operations, said in a blog post Wednesday.
Using UAVs to inspect cell towers is already enabling AT&T to conduct checks more quickly and safely, “and even access parts of a tower that a human simply could not,” he said. “We anticipate this will allow us to improve our customers’ experience by enhancing our cell sites faster than ever before.”
In the future, tethered drones at crowded concerts could allow attendees to more easily send and receive messages, something that’s often hard to do when stationary cell networks are overwhelmed by high service demands, Donovan said. The company’s current tests are expected to “lay the…

NEC Corporation and NTT Corporation have announced the completion of a transoceanic-class transmission experiment spanning 7,280 kilometers.
The experiment utilized a coupled 12-core multicore fiber, showcasing a groundbreaking advancement in optical network technology.
The experiment, a collaboration between NEC and NTT, marks a milestone in the development of next-generation transmission infrastructure critical for the realization of high-capacity optical networks, including future optical submarine cables.
The exponential growth of global 5G adoption and increased communication demands between data centers have led to a 30 percent annual rise in international internet traffic from 2018 to 2022. This trend necessitates enhancements in transmission capacity per optical submarine cable system.
Traditional optical submarine cables utilize single-core fiber, limiting their capacity to a single optical transmission path. In response, research and development efforts worldwide are exploring multicore fiber technology to increase transmission capacity without altering the standard outer diameter of the fiber.
NEC is involved in a project employing two-core multicore fiber for a long-haul optical submarine cable system, demonstrating a commitment to advancing transmission capabilities.
The addition of multiple cores to an optical fiber introduces challenges such as crosstalk, where optical signals from one core interfere with signals in adjacent cores, potentially degrading communication quality. Moreover, long-distance transmission exacerbates issues related to signal delay and loss uniformity.
To address these challenges, NEC and NTT developed innovative technologies:
NEC devised an algorithm leveraging Multiple Input Multiple Output (MIMO) technology for demodulating received signals, enabling accurate separation and demodulation of high-speed signals over long distances.
NTT pioneered design technologies for coupled multicore fiber and optical input/output devices, mitigating the effects of non-uniform signal delay and loss, thus expanding the potential distance of transmission.
By combining these advancements, NEC and NTT achieved a historic feat, successfully demodulating 12-spatially multiplexed optical signals over 7,280 kilometers in a transoceanic-class transmission experiment.
Building upon this success, NEC and NTT will further advance these technologies with the goal of commercializing a long-haul, high-capacity optical submarine cable system and terrestrial core network system. These efforts align with the vision of the IOWN concept and the Beyond 5G/6G era anticipated in the 2030s.
The groundbreaking results will be presented as a highly regarded paper at the Technical Conference of OFC 2024, the world’s premier event on optical communications, scheduled from March 24 to March 28, 2024, at the San Diego Convention Center in California, USA.

From crude mechanical systems to today‘s sleek flat panels, the history of television is defined by innovation. Each new TV format revolutionized the viewing experience – and society – by overcoming limitations of the past. In this journey through vintage TV technology, we‘ll highlight five pivotal eras that trace the evolution from black & white to color, small screens to large, and bulky boxes to streamlined panels.
The Dawn of Television: Mechanical TVs
Television‘s origins trace back to the late 1800s, but it took several decades and false starts before the technology matured. Early TV systems relied on mechanical scanning methods like the spinning Nipkow disk, with its spiral of holes that could rapidly scan lines of an image.
Scottish inventor John Logie Baird capitalized on these early scanning techniques to give the first public demonstration of a "true" television system in 1925. Using a painted ventriloquist dummy named Stooky Bill to provide facial contrast, Baird transmitted a flickering 30-line image that could be viewed in real-time on a monitor.
The following year, Baird successfully transmitted human faces, pioneering the era of mechanical television. Despite its crude 30-60 line resolution, Baird‘s system proved television could work, setting off a wave of development. By 1928, Baird was broadcasting regular TV programming in London, including plays and variety acts captured by primitive scanning cameras.

|1925||John Logie Baird demonstrates mechanical TV system|
|1928||Baird broadcasts regular TV programming in London|
At the same time, inventors like Philo Farnsworth and Vladimir Zworykin pursued a competing approach: electronic television, based on cathode ray tubes. Despite the excitement surrounding Baird‘s mechanical system, it had fundamental limitations. The 30-line resolution produced blurry, flickering images, and the disks would burn out from friction after just a few hours of scanning.
Within a few years, the superior electronic television technology prevailed. Electronic TV combined the scanning capabilities of cathode ray tubes with amplifiers and vacuum tubes to transmit a strong signal, yielding much clearer 60-343 line images. By 1934, Farnsworth gave the first electronic TV demonstration and Zworykin‘s electronic system was adopted by RCA. The mechanical TV era was over after little more than a decade. But it established critical foundations that electronic television built upon.
Black & White TV‘s Golden Age
By 1939, electronic television was ready for public debut at the World‘s Fair. RCA‘s model with a 5" screen cost a hefty $600 (over $11,000 today) to purchase. Initially just a novelty, television took off after WWII, fueled by post-war prosperity and innovations that made sets more affordable.
The number of American households with a TV skyrocketed from under 10,000 in 1946 to over 12 million by 1951. By 1960, nearly 90% of households had a television as black & white TV became central to family life.
|Year||Number of US Households with TV|
|1946||Less than 10,000|
|1960||Over 50 million|
Early B&W sets used small cathode ray tubes to direct electron beams onto phosphor-coated screens. Magnetic coils moved the beams rapidly back and forth across each line of the screen. Images were painted line-by-line from top to bottom in a "raster" pattern to form a full frame 30 times per second, creating the illusion of motion.
With a 525-line scanning resolution, picture quality improved drastically over crude mechanical systems. 12"-15" screens became the norm by the 1950s as prices dropped. But B&W TV technology was not without limitations. Images still degraded depending on signal quality, so rabbit ear antennas had to be adjusted to pull in stations. VHF and UHF dials allowed access to the growing number of channels over the airwaves.
Why did electronic B&W TV succeed where mechanical TV failed? The scanning cathode ray tube proved far superior at transmitting clear, flicker-free images. This reliable technology could scale as demand boomed post-WWII, while mass producing mechanical spinning disks was not practical. Electronic television offered a level of performance that finally fulfilled the public expectation of television, at an affordable price.
The Game-Changing Shift to Color
While experiments with color TV dated back to the 1940s, high costs prevented mass adoption until the mid-1960s. The first color test broadcasts by CBS in 1950 proved promising but crude, with only about 12,000 color TVs in existence.
Color TV relied on combining three beams – one for each primary color – precisely synchronized to scan RGB components together line-by-line. This came at a cost, as much more data transmission was required. NTSC color signals had about 1/3 the resolution of B&W: only about 320 lines compared to over 525.
Despite this shortcoming, the appeal of color TV was undeniable. Sales boomed following the launch of NBC‘s Bonanza in vivid color in 1959. By the mid-1960s, all major networks were broadcasting primetime in color as shows like Laugh-In and Batman leveraged bright, eye-catching palettes and backdrops. The percentage of households with color TVs surpassed B&W in just a few years.
|Year||% of US Households with Color TV|
Despite the poor resolution, color TV technology was an enormous breakthrough. Early adopters tolerated the flaws and cost. For broadcasters, color TV drove demand and opened up new creative opportunities. Sports and news benefited immediately. The shared community experience of watching history unfold in color TV events like the moon landing galvanized the nation. While crude at first, color TV rapidly improved in quality and declined in price throughout the 1970s.
The Race for Bigger Screens
Even as sales of color TVs took off, screen sizes remained relatively modest. Most households still had 25" or smaller screens into the 1970s due to limits in cathode ray tube technology. Beyond 30"-40", CRT TVs become impractically heavy and suffered image distortions.
To drive screen size larger, new innovations were needed. In the late 1960s, projection technology enabled 50-60" screens by beaming CRT images onto the back of reflective screen material. But early rear projection TVs cost over $3,000, limiting adoption.
In the 1980s, prices became more reasonable. Large projection TVs found a niche market for home theaters, sports bars, and other high-end uses. But picture quality was lacking compared to direct-view CRTs. Monster 50" projection sets took up entire living room walls. While novel, the average household still opted for more moderately-sized CRT sets into the 1990s.
|Year||Average TV Screen Size|
Rear projection represented an interim solution on the road to large screens. While the huge sets appealed to home theater enthusiasts, drawbacks included lower image quality, monster footprints, and poor viewing angles. Prices were also slow to drop significantly until the rise of flat panels. For most consumers through the 1990s, direct-view CRTs still offered the best balance on price, performance and size.
The Flat Panel Revolution
By the late 1990s, the next generation of TV technology finally broke past the screen size and performance barriers of CRTs: flat panel displays. Pioneered for niche commercial use earlier, it was not until the 2000s that flat panel TVs became mainstream in homes.
Two technologies drove the flat panel revolution – plasma and LCD.
Plasma TVs use hundreds of thousands of individual pixel cells coated in phosphors. Electrodes excite a neon/xenon gas mixture in the pixels to emit ultraviolet plasma, causing the phosphors to glow red, green or blue and compose an image. Plasma pixels directly emit their own light, allowing for incredible contrast ratios and black levels.
Early on, plasma held image quality advantages over LCD but suffered from screen burn-in. As manufacturing ramped up in the early 2000s, plasma became cost competitive with projection TVs. Screen sizes up to 60" became attainable for under $5,000, fostering rapid adoption.
|Year||Global Shipments of Plasma TVs|
|2008||Over 9 million units|
LCD televisions work by sandwiching liquid crystals between polarized glass panels. Electrical current applied to the crystals manipulates the angle of light passing through them, controlling color and brightness. LCD pixels do not directly emit light, so a backlight is required.
While plasma initially led on picture quality, LCD technology was easier to scale up in size. By the late 2000s, LCD manufacturers like Samsung steadily improved image quality while slashing prices, overtaking plasma in worldwide sales.
|Year||Global LCD TV Shipments|
|2003||20 million units|
|2010||Over 154 million units|
This flat panel price war fueled exponential growth. By 2010, it was possible to purchase giant, razor-thin LCD TVs for under $1,000 – something entirely unfathomable just 10 years earlier. Today, even budget TVs boast 4K resolution, dazzling contrast, and 60-inch+ sizes at prices affordable for any household.
The plasma vs. LCD battle was the last major display technology rivalry. Improving LCD and new OLED panels have become firmly established as today‘s high-end TV technology, leaving vintage CRT and projection systems far behind. We now take affordable, giant, beautiful flat screens for granted – but their rapid rise was nothing short of revolutionary.
The history of television is defined by innovation cycles. Each new TV format – from crude mechanical scanning to today‘s immersive flat panels – built upon the foundations of previous technologies while breaking through barriers like screen size, image clarity, and affordability.
Engineers in the 1920s could hardly imagine that TV would become an indispensable worldwide medium. Yet each era of new display technology brought television closer to its potential. B&W TV turned novelty into mainstream; color added realism. Projection and flat panels finally unlocked large screen sizes for the average household.
The pace of change has been astonishing. Over just 80 years, television morphed from flickering 30-line screens into lifelike 50 inch+ panoramas. Yet pioneers like John Logie Baird and Philo Farnsworth would surely recognize their contributions in today‘s vibrant 4K images. Television has fulfilled its early promise and will continue rapid innovation. The history of old TVs shows how far we‘ve come – and hints at how far the humble television may still evolve in the future.

System identification, highly nonlinear dynamic equations, Arx system identification algorithm, Armax system identification algorithm
System Identification is used to build mathematical models of a dynamic system based on measured data. To design the best controllers for linear or nonlinear systems, mathematical modeling is the main challenge. To solve this challenge conventional and intelligent identification are recommended. System identification is divided into different algorithms. In this research, two important types algorithm are compared to identifying the highly nonlinear systems, namely: Auto-Regressive with eXternal model input (ARX) and Auto Regressive moving Average with eXternal model input (Armax) Theory. These two methods are applied to the highly nonlinear industrial motor.

Intel claims that its latest network card will increase data centre bandwidth tenfold.
The network interface card (NIC) includes 10Gigabit Ethernet to connect data centre servers to 10GigE networks. A lack of links between 10GigE-capable switches (such as the Cisco Catalyst 6500) and servers is holding back its use in data centre, said Intel networking and storage group vice president Hans Geyer.
At present, switches have 10Gb ports but use only the 1Gb port to talk with servers because server adapters do not use the multimode fibre generally used in data centres. Intel's PRO/10GbE SR Server Adapter does, however, so networks gain a tenfold increase in bandwidth.
Intel cards are faster than other 10GigE adapters because of the company's better packaging on the card Geyer claimed, adding that with other cards, the delivered data rate is less than the 10Gb received because of limitations in components, circuitry and packaging.
The card will help with the spread of high-end iSCSi storage area networks, Intel said. However, there is no TCP/IP offload Engine (TOE) on the card, so the host server has to expend CPU cycles processing the TCP/IP protocol algorithms involved, and that could prove quite significant with a 10GigE link.
The adapter's price is £2,690 in the UK, and the maximum link length supported is 300m.

With the rapid advancement of technology, smart doorbells have become an integral part of modern home security systems. These innovative devices offer a range of features aimed at enhancing convenience, security, and user experience. In this article, we will delve into the advanced features of smart doorbells, focusing on data transmission and network bandwidth optimization.
Data Transmission and Network Bandwidth Optimization:
Wi-Fi or Other Wireless Communication Technologies:
Smart doorbell systems typically utilize Wi-Fi or other wireless communication technologies such as Bluetooth or Zigbee to transmit encoded video and audio data to users' smartphones or other devices. Wi-Fi is the most commonly used option due to its high transmission speed and wide coverage range.
To reduce data transmission volume and optimize network bandwidth utilization, doorbell systems employ data compression techniques. Video and audio data are encoded using advanced compression algorithms such as H.264/H.265 for video and AAC for audio, compressing them into smaller data packets, thereby reducing the required bandwidth and transmission time over the network.
During network communication, smart doorbell systems may prioritize the transmission of video and audio data. For instance, the system might prioritize video data transmission to ensure users can timely view surveillance footage, while audio data transmission is given relatively lower priority to ensure the continuity of real-time communication.
Real-Time Stream Processing:
Real-Time Encoding and Decoding:
Video and audio data undergo real-time encoding and decoding during transmission. Doorbell systems may employ hardware acceleration or dedicated processors to achieve real-time encoding and decoding of video and audio, ensuring smooth and seamless transmission during the process.
Dynamic Bandwidth Adjustment:
To adapt to varying network conditions, smart doorbell systems may implement dynamic bandwidth adjustment functionality. The system automatically adjusts the transmission rate and quality of video and audio data based on the current network status, ensuring stable transmission and a good viewing experience under different network conditions.
The implementation of high-definition video and audio transmission in smart doorbells addresses users' needs for home security monitoring and remote communication, significantly enhancing their user experience. Through effective data compression, priority management, and real-time stream processing technologies, smart doorbell systems can achieve stable transmission of high-definition video and audio even under various network conditions, providing users with a more convenient and secure user experience.

How to save electricity at work
Energy consumption has reached an all time high in the United States. As of 2008, the U.S. Department of Energy estimated that commercial buildings consumed almost 20 percent of the total energy used in the U.S. An office manager or business owner looking to reduce the office's energy use can invest in a variety of procedural and equipment changes.
Cutting energy use with more efficient technology can be a benefit for the office both socially and economically. Here are a few effective steps to saving electricity at work.
1. Switch from incandescent light bulbs to LEDs. An LED light bulb may cost more initially than an incandescent bulb, however it offers cost and energy savings in the long run. An LED light bulb uses 75 percent less energy than traditional light bulbs and lasts six times longer. It will save about $6 a year in electricity costs and approximately $40 over the lifetime of the longer lasting bulb.
2. Put LED lights on a lighting management system. Using timers and motion sensors, the lights in an office building can turn themselves off when no one is using a space. Prioritize upgrading lighting to heavy-traffic areas, such as conference rooms, hallways and bathrooms, which can easily save an office a few thousand dollars in electricity costs over time.


Last two years, Microsoft has been planning the foldable phone with two screen display and still has not yet launched the device.
The dual-screen device has a codenamed Andromeda. The upcoming device has released its images or sketches in patents, reports, and systems many times. According to The Verge, Microsoft’s internal document about the said device is going to be suitable in a pocket Surface device that has upgraded to new hardware and software experiences.
The project about Andromeda is still being upgraded that is only open inside the company and it is confirmed that it will create a new and disruptive device. Microsoft said that Andromeda will create a truly personal and flexible computing experience. The device will have its wraparound display that connects the two screens with the used of hinge. It will include a pen for the touchscreen of the phone.
The company has not yet responded to the requests and confirmation of news companies.


Vanadium dioxide (VO2) has emerged as a promising micro-actuator material for its large amplitude and high work density across the transition between the insulating (M1 and M2) and metallic (R) phase. Even though M2–R transition offers about 70% higher transformation stress than M1–R structural phase transition, the application of the M2 phase in the micro-actuators is hindered by the fact that previously, M2 phase can only stay stable under tensile stress. In this work, we propose and verify that by synthesizing the VO2 nanowires under optimized oxygen-rich conditions, stoichiometry change can be introduced into the nanowires (NWs) which in turn yield a large number free-standing single-crystalline M2-phase NWs stable at room temperature. In addition, we demonstrate that the output stress of the M2-phase NWs is about 65% higher than that of the M1-phase NWs during their transition to R phase, quite close to the theoretical prediction. Our findings open new avenues towards enhancing the performance of VO2-based actuators by using M2–R transition. [Figure not available: see fulltext.].

I will present the latest results from the Karlsruhe Tritium Neutrino Experiment (KATRIN). KATRIN probes the effective mass of electron anti-neutrinos via a high-precision measurement of the β-decay spectrum of tritium near its endpoint at 18.6 keV. In the first campaign, KATRIN established that the effective mass of neutrinos is <1.1 eV/c2 (90% CL). In the second physics campaign, the source activity was increased by a factor of 3.8 and the background was reduced by 25% compared to the first campaign. Combining the currently available KATRIN data, we find a new upper limit on the effective neutrino mass at <0.8 eV/c2 (90% CL).

The Lorentz Contact Resonance (LCR) imaging mode further enhances the capabilities of the afm+ and nanoIR systems. LCR allows rapid broadband nanomechanical measurements over a range of temperatures, identifying key sample measurement contrasts, and allowing precise probe placement for subsequent chemical or thermal analysis with nanoscale resolution.
How it works
Because there are no moving parts actuating the cantilever, Lorentz Contact Resonance provides a very clean excitation over broad frequency ranges (bottom plot). Piezo drive schemes (top plot) can excite many spurious resonances that interfere with contact resonance measurements and interpretation of the results.
Mechanical property insights
Left: A selection of LCR nanomechanical spectra obtained on different polymers. Different polymers can be distinguished on the basis of position and/or height of contact resonances in the LCR spectra.
Multi-component samples can be imaged at multiple frequencies, identifying and imaging each component individually. The Analysis Studio software can then be used to create an RGB overlay image.

Electrical Engineering ⇒ Topic : Molecular Theory of Magnetism
Molecular Theory of Magnetism
The molecular theory of magnetism was proposed by Weber in 1852 and modified by Ewing in 1890. According to this theory, every molecule of a magnetic substance (whether magnetised or not) is a complete magnet in itself having a north pole and a south pole of equal strength.
In an unmagnetised substance, the molecular magnets are randomly oriented and form closed chains as shown in Fig. a (i). The north pole of one molecular magnet cancels the effect of the south pole of the other so that the substance does not show any net magnetism.
When a magnetising force is applied to the substance (e.g. by rubbing a magnet or by passing electric current through a wire wound over it), the molecular magnets are turned and tend to align in the same direction with N-pole of one molecular magnet facing the S-pole of other as shown in Fig. a (ii). The result is that magnetic fields of the molecular magnets aid each other and two definite N and S poles are developed near the ends of the specimen ; the strength of the two poles being equal. Hence the substance gets magnetised.
The extent of magnetisation of the substance depends upon the extent of alignment of molecular magnets. When all the molecular magnets are fully aligned, the substance is said to be saturated with magnetism.
When a magnetised substance (or a magnet) is heated, the molecular magnets acquire kinetic energy and some of them go back to the closed chain arrangement. For this reason, a magnet loses some magnetism on heating
