Implant Gives Grayscale Vision To the Blind Using Lasers 165

Posted by Unknown Lamer from the not-safe-for-mcdonald's dept.
MrSeb writes with a bit from Extreme Tech: "After a lot of theorizing, posturing, and non-human trials, it looks like bionic eye implants are finally hitting the market — first in Europe, and hopefully soon in the U.S. These implants can restore sight to completely blind patients — though only if the blindness is caused by a faulty retina, as in macular degeneration (which millions of old people suffer from), diabetic retinopathy, or other degenerative eye diseases. ... The Bio-Retina, developed by Nano Retina, is a whole lot more exciting. The Bio-Retina costs ... around the $60,000 [and] the 576-pixel vision-restoring sensor is actually placed inside the eye, on top of the retina. The operation only takes 30 minutes and can be performed under local anesthetic. Once installed, 576 electrodes on the back of the sensor implant themselves into your optic nerve. The best bit, though, is how the the sensor is powered: The Bio-Retina system comes with a standard pair of corrective lenses that are modified so that they can fire a near-infrared laser beam through your iris to the sensor at the back of your eye. On the sensor there is a photovoltaic cell that produces up to three milliwatts — not a lot, but more than enough."

Sony's Thermal Sheet Good As Paste For CPU Cooling 195

Posted by timothy from the also-better-with-salsa dept.
An anonymous reader writes "Sony has demonstrated a thermal sheet that it claims matches thermal paste in terms of cooling ability while beating it on life span. The key to the sheet is a combination of silicon and carbon fibers, to produce a thermal conductive layer that's between 0.3 and 2mm thick. In the demonstration, the same CPU was cooled by thermal paste and the thermal sheet side-by-side, with the paste keeping the processor at a steady 53 degrees Celsius. The sheet achieved a slightly better 50 degrees Celsius. The actual CPU used in the demonstration wasn't identified. Sony wants to get the thermal sheet used in servers and for projection units, but I can definitely see this being an option for typical PC builds, too. It's certainly going to be less messy and probably a lot cheaper than buying a tube of thermal paste."

Man Physically Assaulted At McDonald's For Wearing Digital Eye Glasses 1198

Posted by Soulskill from the i-don't-think-he's-lovin'-it dept.
RockoW writes "Steve Mann, a long-time researcher of computer vision systems, (i.e. Augmented reality, Digital Eyeglass) had an incident at a McDonald's in Paris, France. He was assaulted by three men during his visit to get food with his family. They had a problem with his digital eye glasses and tried to take them off his head. 'The eyeglass is permanently attached and does not come off my skull without special tools.' The men also tore up Mann's documentation and a letter from his doctor explaining the device's use. Fortunately, the rough treatment of the device caused it to keep recent images in its memory, instead of quickly overwriting them, so Dr. Mann has pictures of the men who assaulted him."

Thirty Years of Clamshell Computing 135

Posted by samzenpus from the form-factor dept.
harrymcc writes "2012 marks the thirtieth anniversary of the Grid Compass 1101, the first portable computer with a briefcase-like case with a keyboard on one side of the interior, a flat screen on the other, and a hinge in the middle--the 'clamshell' design that eventually became standard for all portable PCs. It's proven to be a remarkably useful and durable design, and only with the advent of the iPad has it faced serious competition."

Record Setting 500 Trillion-Watt Laser Shot Achieved 252

Posted by samzenpus from the not-in-the-eyes dept.
cylonlover writes "Researchers at the Lawrence Livermore National Laboratory's National Ignition Facility (NIF) have achieved a laser shot which boggles the mind: 192 beams delivered an excess of 500 trillion-watts (TW) of peak power and 1.85 megajoules (MJ) of ultraviolet laser light to a target of just two millimeters in diameter. To put those numbers into perspective, 500 TW is more than one thousand times the power that the entire United States uses at any instant in time."

Order Limit On Raspberry Pi Lifted 204

Posted by samzenpus from the I'll-take-a-bag-full dept.
hypnosec writes "Raspberry Pi, the small $35 ARM-based computer system capable of running Linux that took the world of technology by storm just a few months back, has its order limit shackles removed as it has been revealed that manufacturers are now producing 4000 units per day. The Raspberry Pi Foundation, the non-profit organization behind the tiny computer, has said that RS Components and element14/Premier Farnell have started producing enough units to allow them to scrap the order limit on Raspberry Pi. In a blog post, the foundation made the announcement. Initially the limit of one unit per customer was placed in the light of limited stocks. Despite these limits, there was always a shortage and people had to wait for long time to get their hands on one of these credit card sized computers."

Georgie: Smartphone For the Blind and Visually Impaired 77

Posted by samzenpus from the equal-opportunity dept.
hypnosec writes "A specially designed smartphone for the visually impaired or partially sighted has been launched in the UK. The device, dubbed Georgie, has many special features including a voice-assisted touch screen and apps that will allow for easy completion of day-to-day tasks like catching a bus, reading printed text and pinpointing a location. Designed by a blind couple, Roger and Margaret Wilson-Hinds, and named after Mrs Wilson-Hind's guide dog, the smartphone is powered by the Android operating system and uses handsets like Samsung XCover and Galaxy Ace 2, notes the BBC. The main reason for developing such a phone, according to the couple, was that they wanted to get the technology across to people with very little or no sight. 'It's exactly the type of digital experience we want to make easily available to people with little or no sight,' said Roger."

How the Inventors of Dragon Speech Recognition Technology Lost Everything 606

Posted by samzenpus from the all-the-eggs-in-one-basket dept.
First time accepted submitter cjsm writes "James and Janet Baker were the inventors of Dragon Systems' speech recognition software, and after years of work, they created a multimillion dollar company. At the height of the tech boom, with investment offers rolling in, they turned to Goldman Sachs for financial advice. For a five million dollar fee, Goldman hooked them up with Lernout & Hauspie, the Belgium speech recognition company. After consultations with Goldman Sachs, the Bakers traded their company for $580 million in Lernout & Hauspie stock. But it turned out Lernout & Hauspie was involved in cooking their books and went bankrupt. Dragon was sold in a bankruptcy auction to Scansoft, and the Bakers lost everything. Goldman and Sachs itself had decided against investing in Lernout & Hauspie two years previous to this because they were lying about their Asian sales. The Bakers are suing for one billion dollars."

MIT Creates Car Co-Pilot That Only Interferes If You're About To Crash 238

Posted by samzenpus from the robot-take-the-wheel dept.
MrSeb writes "Mechanical engineers and roboticists working at MIT have developed an intelligent automobile co-pilot that sits in the background and only interferes if you're about to have an accident. If you fall asleep, for example, the co-pilot activates and keeps you on the road until you wake up again. Like other autonomous and semi-autonomous solutions, the MIT co-pilot uses an on-board camera and laser rangefinder to identify obstacles. These obstacles are then combined with various data points — such as the driver's performance, and the car's speed, stability, and physical characteristics — to create constraints. The co-pilot stays completely silent unless you come close to breaking one of these constraints — which might be as simple as a car in front braking quickly, or as complex as taking a corner too quickly. When this happens, a ton of robotics under the hood take over, only passing back control to the driver when the car is safe. This intelligent co-pilot is starkly contrasted with Google's self-driving cars, which are completely computer-controlled unless you lean forward, put your hands on the wheel, and take over. Which method is better? A computer backup, or a human backup? I'm not sure."

NVIDIA Kills Online Store In Response To Hacker Claims 70

Posted by Soulskill from the have-you-tried-updating-your-drivers dept.
wiredmikey writes "Following a shutdown of its 'NVIDIA Developer Zone,' earlier this week after the online community for developers had been hacked, the graphics chip maker on Friday also shut down its online store. The group of hackers behind the attack, going by the handle of 'The Apollo Project,' made mention of the claimed compromise in its original post exhibiting its successful attack against the NVIDIA Developer Zone site. While the company has shut down the online store, it has not acknowledged that a successful attack has taken place. 'NVIDIA has suspended operation of the NVIDIA Gear Store (store.nvidia.com) as a precaution, following confirmed attacks on several of our other sites,' read a statement posted on the site posted. The claimed attackers wrote, 'We aren't acting extremely maliciously, we've used this database to target disgusting corporations who deserve to be brought to justice.. and we are getting there, slowly but surely.'"

Has the 3-D Hype Bubble Finally Popped? 261

Posted by Soulskill from the let's-hope-so dept.
An anonymous reader writes "An article at Time speculates that the recent hype surrounding 3-D display technology has finally peaked and begun to subside. As evidence, they point to comments from Nintendo president Satoru Iwata, who does not seem particularly enthusiastic about it, and concedes it won't be a major selling point if the company continues to have 3-D enabled products in the future. He said, 'So, now we've created the 3DS and 3DS XL and also have some games out there that are really using that 3D effect that we can see, from my point of view, that it's an important element. But as human beings are this kind of surprise effect wears off quickly, and just [having] this 3D stereoscopic effect isn't going to keep people excited.' Revenue from 3-D films is also dropping, and while 3-D television sales are rising, only 14 percent of potential buyers think 3-D is a 'must have' feature."

Ask Slashdot: Building a Personal FOSS Cloud? 189

Posted by timothy from the and-you-will-always-have-shade dept.
An anonymous reader writes "Cloud-based personal data management is pretty cool... if you don't mind entrusting the entirety of your personal data to a gigantic corporation. Apart from the risks of their doing unseemly things with your data, also the security of your data is entirely in their unreliable hands. So, is it possible to build my own personal data repository, where for example, I can store my contacts and calendars to sync to multiple devices? This could be hosted on any third party hosting service assuming also that all of my data was encrypted at the data level. So even if the host wanted to look at my data, all they'd see is 1s and 0s. What are the options for the tinfoil hat wearing FOSS folks that want to participate in the cloud age?"

MIT Develops Holographic, Glasses-Free 3D TV 98

Posted by samzenpus from the realer-than-real dept.
MrSeb writes "Engineers at the Massachusetts Institute of Technology (MIT) are busy working on a type of 3D display capable of presenting a 3D image without eye gear. What you've been presented with at your local cinema (with 3D glasses) or on your Nintendo 3DS console (with your naked eye) pales in comparison to what these guys and gals are trying to develop: a truly immersive 3D experience, not unlike a hologram, that changes perspective as you move around. The project is called High Rank 3D (HR3D). To begin with, HR3D involved a sandwich of two LCD displays, and advanced algorithms for generating top and bottom images that change with varying perspectives. With literally hundreds of perspectives needed to accommodate a moving viewer, maintaining a realistic 3D illusion would require a display with a 1,000Hz refresh rate. To get around this issue, the MIT team introduced a third LCD screen to the mix. This third layer brings the refresh rate requirement down to a much more manageable 360Hz — almost within range of commercially produced LCD panels."

A Million-Year Hard Disk 394

Posted by samzenpus from the sapphires-are-forever dept.
sciencehabit writes "Pity the builders of nuclear waste repositories. They have to preserve records of what they've buried and where, not for a few years but for tens of thousands of years, perhaps even millions. Trouble is, no current storage medium lasts that long. Today, Patrick Charton of the French nuclear waste management agency ANDRA presented one possible solution to the problem: a sapphire disk inside which information is engraved using platinum. The prototype shown costs €25,000 to make, but Charton says it will survive for a million years. The aim, Charton says, is to provide 'information for future archaeologists.' But, he concedes: 'We have no idea what language to write it in.'"

PC Sales Are Flat-Lining 485

Posted by timothy from the more-like-personal-computer-is-changing-its-meaning dept.
DavidGilbert99 writes "Gartner has released figures showing that PC shipments globally declined 0.1 percent in the last three months, making it the seventh consecutive month of little-to-no growth in the PC market. This was despite the launch a number of new Ultrabooks, the much-vaunted slim-and-light platform promoted by Intel. The decline has been put down to the poor economic situation around the globe, increased spending on tablets and smartphones instead of PCs as well as the imminent launch of Windows 8, making people hold out on updating their PCs."

The DHS's Latest Investment: Terahertz Laser Scanners 169

Posted by Soulskill from the can-we-shoot-you-with-this-laser-to-uhhhh-scan-you? dept.
MrSeb writes "It seems like every time I set foot in an airport, there is some new machine I need to stand in, walk through, or put my shoes on. The argument can be made that much of this is security theater — an effort to just make things look safe. However, if a new kind of laser-based molecular scanner lives up to its promise and finds its way into airports as planned, it could actually make a difference. A company called Genia Photonics has developed a programmable picosecond laser that is capable of spotting trace amounts of a variety of substances. Genia claims that the system can detect explosives, chemical agents, and hazardous biological substances at up to 50 meters. This device relies on classic spectroscopy; just a very advanced form of it. In the case of Genia's scanner, it is using far-infrared radiation in the terahertz band. This is why the U.S. Department of Homeland Security is so keen on getting it into airports. Understandably, some are calling foul on the possible privacy concerns, but this technology is halfway to a Star Trek tricorder."
