  • http://www.nist.gov/pml/div684/limit-010813.cfm Communicating with light may soon get a lot easier, hints recent research* from the National Institute of Standards and Technology (NIST)and the University of Maryland's Joint Quantum Institute (JQI), where scientists have potentially found a way to overcome a longstanding barrier to cleaner signals.The findings, which demonstrate for the first time an error rate far below the "standard quantum limit" for a wide range of light levels, could increase the efficiency of fiber-optic systems by reducing both the power needed to send a signal and the number of errors the receiver makes.The research team, though, found a clever way to get past the standard quantum limit using off-the-shelf technology to construct a receiver in an innovative way. Their solution is to make several measurements instead of a single one, and set them up so that each measures a portion of the input light's phase state successively. The key to this "staged" approach is that the receiver makes a partial measurement of the input phase state, and then uses the information obtained from this first partial measurement to adapt itself before making the next one. None of the individual partial measurements is perfect, but the adaptive technology allows a dramatically better final result.
  • SiC Could Eclipse Diamond In Quantum ComputersJan 07, 2013By creating a silicon vacancy defect in silicon carbide, scientists have generated additional energy levels in the so band gap for use in supercomputersResearchers from the University of Würzburg have modified SiC crystals to exhibit new and surprising properties.This makes them interesting with regard to the design of high-performance computers or data transmission.SiC crystals consist of a regular lattice formed by silicon and carbon atoms. At present, these semiconductors are extensively used in micro and optoelectronics. They are particularly suited for used in high temperature applications in power semiconductors.Now physicists from Saint Petersburg and the University of Würzburg have succeeded in manipulating SiC in a way so it can be used in novel, super-fast quantum computers.http://www.compoundsemiconductor.net/csc/news-details.php?cat=news&id=19735894
  • Some of you rightly are somewhat worried by the level of surveillance that our much beloved technology makes possible and even perhaps inevitable. So what of a new locations system much more powerful and accurate, even inside buildings and at different heights, than GPS? Of course there are many good things such and advance can be used for. I am certainly a fan. This can pinpoint your location, indoors or out, within in about 4 inches. Locata uses ground-based equipment to project a radio signal over a localised area that is a million times stronger on arrival than GPS. It can work indoors as well as out, and the makers claim the receivers can be shrunk to fit inside a regular cellphone. Even the US military, which invented GPS technology, signed a contract last month agreeing to a large-scale test of Locata at the White Sands Missile Range in New Mexico."This is one of the most important technology developments for the future of the positioning industry," says NunzioGambale, CEO and co-founder of the firm Locata, based in Griffith, Australia.Indoor positioning is the next big thing in location-tracking technology, and companies from Google to Nokia have jumped at the chance to prevent users getting lost in cavernous shopping malls, or in the concrete canyons of big cities, where GPS struggles to keep up. But their technologies typically have a short range, and location resolutions in the order of a few metres.By contrast, Christopher Morin of the US Air Force tested Locata's accuracy recently at White Sands, and it worked to within 18 centimetres along any axis. Morin says it should be possible to get the resolution down to 5 centimetres.
  • CES -- NVIDIA today introduced NVIDIA® Tegra® 4, the world's fastest mobile processor, with record-setting performance and battery life to flawlessly power smartphones and tablets, gaming devices, auto infotainment and navigation systems, and PCs.Tegra 4 offers exceptional graphics processing, with lightning-fast web browsing, stunning visuals and new camera capabilities through computational photography.Previously codenamed "Wayne," Tegra 4 features 72 custom NVIDIA GeForce™ GPU cores -- or six times the GPU horsepower of Tegra 3 -- which deliver more realistic gaming experiences and higher resolution displays. It includes the first quad-core application of ARM's most advanced CPU core, the Cortex-A15, which delivers 2.6x faster web browsing and breakthrough performance for apps.Tegra 4 also enables worldwide 4G LTE voice and data support through an optional chipset, the fifth-generation NVIDIA Icera® i500 processor. More efficient and 40 percent the size of conventional modems, i500 delivers four times the processing capability of its predecessor."Tegra 4 provides enormous processing power and efficiency to power smartphones and tablets, gaming devices, auto systems and PCs," said Phil Carmack, senior vice president of the Tegra business at NVIDIA. "Its new capabilities, particularly in the area of computational photography, will help improve a whole range of existing products and lead to the creation of exciting new ones."Computational Photography CapabilityAmong the Tegra 4 processor's breakthroughs is its Computational Photography Architecture, which automatically delivers high dynamic range (HDR) photos and video by fusing together the processing power of the GPU, CPU and the camera's image-signal processor.Its HDR capability captures images, including those taken with a flash, the way they are seen by the human eye -- with detail in both bright and dark areas.
  • Firefox opens up a new front in the smartphone war with its own OS that can help turn any website into an app, and bring greater interaction with the phone's hardware features to the fore. A Little Bit of HardwareYes, smartphones are already full of apps and browsers to access websites, but Firefox OS will help turn your HTML5 website into an app that can interact with the camera, GPS and other features of your phone to bring greater interactivity. It will also keep alive the idea of a truly open ecosystem in this increasingly closed mobile OS world. Previously under development as the Boot to Gecko program, the OS was unveiled late last year. Is this a new rival to Android and iOS, or just another side project? To prevent the latter, there's even a developer phone to encourage uptake. It packs a modest spec, but enough to get people interested in the ecosystem.

  • http://www.youtube.com/watch?feature=player_embedded&v=_d6KuiuteIA device that makes it possible to control a computer with fluid midair finger motions will be bundled with some PCs from Taiwanese company Asus in coming months. The distribution deal is the most significant move yet by startup company Leap Motion to distribute its first product, which allows desktop software to respond to swipes, pokes, and grabs made in front of a screen (see “Leaping Into the Gesture-Controlled Era”).The deal will see Leap Motion’s sensors and software packaged with some “high-end” laptops and PCs. The bundled products will appear in the first quarter of 2013, says Leap, around the same time the standalone Leap Motion device, priced at $70, is due to begin shipping.Michael Buckwald, Leap Motion’s cofounder and CEO, says Asus agreed to use his company’s technology because it believes new ideas are necessary in the PC market. “They, like us, believe this will revolutionize interaction on the PC platform,” says Buckwald.The Leap device is roughly the size of a pack of gum: three inches long, one inch wide and half an inch thick. One side is black glass, under which are two small cameras and a handful of infrared LEDs gather the data needed to track fingers to an accuracy of one hundredth of a millimeter.Buckwald says that the same functionality could be added to even smaller devices. “Even today, it is possible to put Leap into a tablet or smartphone,” he says, by using smaller sensors. “The accuracy and power will stay the same.”
  • For the past nine months, Google has been priming the public for the launch of Google Glass, a head-mounted, Internet-enabled display that—if you buy the hype—will revolutionize computing and totally rock your world.A marketing blitz featured skydivers sporting Glass as they plummeted to Earth and runway models doing their best to strike a modish pose with the smart glasses perched on their noses. A YouTube video promoting the new specs tailed a man as he woke up, ate breakfast, went to a bookstore, met a friend, and shared a sunset with his girlfriend, all while receiving a stream of messages and augmented information about his surroundings on his Google Glass display.In the next few months, Google will start shipping its smart spectacles to developers. More-polished consumer models are expected in 2014.Details about Glass are still sketchy but here’s what we know. The lightweight browband, which looks like an ordinary pair of reading glasses minus the lenses, connects to an earpiece that has much the same electronics you’d find in an Android phone: a micro processor, a memory chip, a battery, a speaker, two microphones, a video camera, a Wi-Fi antenna, Bluetooth, an accelerometer, a gyroscope, and a compass. The microdisplay is positioned over one eye.That hardware lets Glass record its wearer’s conversations and surroundings and store those recordings in the cloud; respond to voice commands, finger taps, and swipes on an earpiece that doubles as a touch pad; and automatically take pictures every 10 seconds. Prototypes connect to the Internet through Wi-Fi or through Bluetooth and a smartphone. Future versions will likely include a cellular antenna.The company says Glass will be small enough, light enough, and stylish enough to wear all day, like a favorite fleece or a comfy pair of sneakers. Glass will run apps like Google+ and Google Search, but it’s designed to feel more natural and immersive than a PC or a smartphone. Ideally, BabakParviz, the leader of Project Glass, told developers at the company’s Google I/O conference in June, it will let you access information “so fast that you feel you know it.” [Parviz elaborates on Google’s plans for Glass in this Q&A.]That’s right: Google says that Glass will make you feel smarter. “We’re talking about a device that sees every thing you see and hears everything you hear,” says Rod Furlan, an artificial intelligence researcher and angel investor. “From the starting line what you are gaining is total recall.”Steve Mann, a professor at the University of Toronto who pioneered the development of Glass-like devices in the 1980s, says Google appears to be making some of the same design mistakes he made with his early proto types. Specifically, he says, positioning a micro display outside a person’s natural field of view could lead to eyestrain and visual confusion. “It doesn’t make you smarter. It makes you dizzier and more confused,” he says, adding that the display should be directly in front of the eye, like a product he developed called EyeTap. [Mann has more to say about his 30 years of research on smart glasses in this Q&A.]Even if Mann’s worries prove unfounded, Glass’s battery life and processing heft will be a big issue; any application involving computer vision and streaming video will likely be a power and computing hog. Right now, the batteries reportedly last just 6 hours. Some developers are also grumbling about the $1500 price tag for the early prototypes. Presumably, the consumer version will be cheaper.
  • Stored in DNAA team of researchers headed by Nick Goldman and Ewan Birney at the European Bioinformatics Institute of the European Molecular Biology Laboratory (EMBL-EBI) has dramatically demonstrated the potential of the technique to store and transport human-made data.Their data included some well-chosen iconic elements: Shakespeare’s 154 sonnets, an audio excerpt from Martin Luther King’s “I have a dream” speech, Watson and Crick’s classic paper on the structure of DNA, and a colour photograph of the European Bioinformatics Institute.These files, in common digital formats found on almost every desktop computer, were encoded byte-by-byte as DNA molecules, shipped from the USA to Germany without specialised packaging, and finally decoded back into their original electronic formats.Although the study involved less than a megabyte of data in total, this is already orders of magnitude more than has previously been encoded as synthesised DNA.The authors argue convincingly that the technique could eventually be scaled up to create a storage capacity far beyond all the digital information stored globally today (somewhere in the vicinity of 1 zettabyte or 1015 megabytes).DNA has substantial advantages over both printed text and electronic media. For one thing, it can remain stable for long periods of time with a minimum of care. Intact DNA has been extracted from bones (and other organic matter) tens of thousands of years old, and its sequence reconstructed with as much detail as if it had come directly from a living organism.Another advantage of DNA over electronic media is that it requires no power supply to maintain its integrity, which makes it easy to transport and store, and potentially less vulnerable to technological failure.Perhaps the greatest advantage of DNA as a storage medium is its minuteness. For example, EMBL-EBI’s official press release claims that more than 100 million hours of high-definition video could be stored in roughly a cup of DNA.We’re getting thereDNA storage devices won’t be available in the supermarket any time soon. The major drawback is the current cost of synthesising DNA in the quantities required, estimated at around US$12,400 per megabyte of data stored.This is cost-effective only for archives intended to last hundreds or even thousands of years—something few of us contemplate.The main cost of maintaining electronic archives over such a long period of time is that the media have to be periodically replaced and the data copied, whereas DNA has merely to be stored somewhere cool, dry and dark.But if the cost of synthesising DNA can be reduced by one or two orders of magnitude—which, judging by current trends could occur within a decade—DNA archives intended to last less than 50 years would become feasible.http://machineslikeus.com/news/dna-data-storage-100-million-hours-hd-video-every-cup/page/0/1
  • Audi Shrinks the Autonomous CarThe company reveals that it is testing driverless cars on Nevada freeways, and shows a compact laser scanner intended to fit such technology into commercial vehicles.Audi has been testing self-driving vehicles on a stretch of Interstate 15 in Nevada, and in parking garages in Las Vegas, the company announced at the Consumer Electronics Show today.The company also showed off a compact laser scanner for autonomous vehicles that is small enough to fit into the grill of a car. Laser scanners make it possible for autonomous vehicles to sense their surroundings, but driverless cars typically sport large, roof-mounted scanners.Audi’s fist-sized laser scanner is designed to scan ahead and to the sides of a vehicle, said Hudi, and is cheaper than the roof-mounted scanners seen on top of autonomous cars such as the one developed by Google. Hudi also showed a prototype circuit board intended to take over the job of the computers that take up space inside Audi’s current research vehicle. “All the systems you see in the trunk today will be replaced by that.”Audi has been carrying out its driverless car research using the first-ever license issued by the Nevada DMV under a law that took effect last year allowing the licensing of autonomous cars.http://www.technologyreview.com/news/509676/audi-shrinks-the-autonomous-car/
  • (Phys.org)—Springtime will spring a new two-screen smartphone in Japan from NTT Do Como, and there is a lot of talk in the air already about what the new Medias WN-05E will spell for a rising tide of form factors now dubbed "phablets." The two-screens in this phone are hinged back to back and provide the user with the opportunity to use the screens independently of each other—playing a game on one screen, for example, while checking out a map on the other screen—or having the two screens behave as one bigger screen. The smartphone is slated for an April release; pricing and a time frame to launch the phone outside Japan are not yet known. The two-screen Medias W, with an 8.1MP camera, is an Android 4.1 smartphone; there are two 960 x 540 4.3-inch screens displays, and it has a 1.5GHz Qualcomm Snapdragon MSM8960 processor. The LCD screens are on the outside of the clamshell rather than the inside. The clamshell-shaped device, when unhinged, has screens that can operate side to side if you wish to multitask, or can be combined into a larger screen. DigInfo TV has carried a video showing the phone and its functions. A map is shown on both screens; a user could check out a map on the bigger screen, putting up with the line seam in the middle, but would be able to pinch and zoom across the pair of screens.Read more at: http://phys.org/news/2013-01-medias-n-05e-wings-two-screen-smartphone.html#jCphttp://www.youtube.com/watch?feature=player_embedded&v=_DQ4RDQMg8I#!
  • Even though data rates are increasing significantly with 11ac, to as high as 6.93Gbps under certain specialized conditions, power consumption will decrease for equivalent data rates, making 11ac much friendlier for mobile devices. 802.11n is pushing the power limits, especially for mobile/portable devices, to the point where most portable devices cannot come close to taking full advantage of 11n capabilities. Through the use of more efficient data encoding mechanisms, 11ac allows devices to use fewer multiple transmissions paths while still achieving higher data rates, and it’s the additional RF transmission chains that really eat up power. In 11ac you’ll see a 3x improvement in data rate over 11n for the same number of MIMO bit streams.While 802.11ac is not scheduled for IEEE ratification until December 2013, companies like Apple and Netgear are already making announcements regarding 11ac support, and consumer products are expected on the market as early as the end of 2012.From the consumer perspective, 802.11ac will provide the ability to fully support a ‘multi-media home’ through its single-link and multi-station enhancements, allowing for simultaneous streaming of HD video to multiple devices throughout the home, rapid synchronization and backup of large data files, wireless display, and 3G and 4G offloading, to name a few. Essentially, with 11ac, you’ll be able to wirelessly network your TV, DVR, smart phone, and sound system for complete on-demand access through an AP or other Internet-connected device.

  • Chamtech has developed the “Spray-On Antenna” to assist intelligence gathering operations by concealing the antennas for equipment that needs to transmit and or receive in frequency bands from 1 MHz through 6.4 GHz. The antenna paint has thousands on nanocapacitors that are far more efficient (so they do not build up heat) than antennas with wires. This technology can boost wireless range by a large amount. RFID range is boosted from 5 feet to 700 feet.http://nextbigfuture.com/2012/08/solve-for-x-low-power-wireless.htmlDARPA’s 100 Gb/s RF Backbone (100G) project intends to develop a fiber-optic-equivalent communications backbone that can be deployed worldwide. The goal is to create a 100 Gb/s data link that achieves a range greater than 200 kilometers between airborne assets and a range greater than 100 kilometers between an airborne asset (at 60,000 feet) and the ground. http://nextbigfuture.com/2012/12/darpa-creating-100-gigabit-per-second.htmlAmerican and Israeli researchers have used twisted, vortex beams to transmit data at 2.5 terabits per second. This twist encoding technique is likely to be used in the next few years to vastly increase the throughput of both wireless and fiber-optic networks. http://nextbigfuture.com/2012/06/adding-twist-dimension-to-communication.htmlNTT is using elastic optical path networks to achieve 1 terabit per second communication and others are developing graphene-Based Optical Modulators to boost communication speed by ten times. http://nextbigfuture.com/2012/03/on-path-to-1-terabit-per-second.htmlNTT demonstrated one petabit per second transmission over one optical fiber over a 50 kilometer distance and are working to get another ten times boost in speed. http://nextbigfuture.com/2012/09/world-record-one-petabit-per-second.html
