MP3 is dead, long live AAC
MP3, the format that revolutionized the way we consume (and steal) music since the 90s, has been officially retired -- in a manner of speaking. The German research institution that created the format, The Fraunhofer Institute for Integrated Circuits, announced that it had terminated licensing for certain MP3-related patents...in other words, they didn't want to keep it on life support, because there are better ways to store music in the year 2017. Rest now forever, MP3.
Wave goodbye to manual car seat controls with gesture tech
It sounds a bit like an infomercial: Tired of using manual controls and levers to adjust your car seats? There's got to be a better way! And now of course there is, thanks to researchers at the Fraunhofer Institute for Silicate Research ISC. The researchers, in conjunction with Isringhausen GmbH & Co. KG, have developed a fully functional prototype that allows drivers to adjust a seat using only hand gestures.
Your smartphone's WiFi hotspot might double as a disaster rescue beacon
When disasters strike, communication services tend to go down; you can't simply call for help or share your location online. However, engineers at the Fraunhofer Institute for Applied Information Technology have found a way to use a smartphone as a rescue beacon when there aren't any available networks. The researchers have written a victim app that inserts an SOS alert into the name of the phone's WiFi hotspot. Emergency crews just have to use a companion app to find you up to 330 feet away. It's a simple trick, to be sure. The big challenge is getting people to use the software in the first place -- the team would like its code built into your phone's interface, but they might have to find a way to distribute their apps in the field. If Fraunhofer's staff succeed in making the tools commonplace, though, you may soon find a ready-made distress signal in your pocket. [Image credit: United Nations Photo, Flickr]
Fraunhofer develops extra-small 1Gbps infrared transceiver, recalls our PDA glory days
Our 1997-era selves would die with envy right about now. Fraunhofer has developed a new generation of infrared transceiver that can transfer data at 1Gbps, or well above anything that our vintage PDAs could manage. While the speed is nothing new by itself -- we saw such rates in 2010 Penn State experiments -- it's the size that makes the difference. The laser diode and processing are efficient enough to fit into a small module whose transceiver is as large as a "child's fingernail." In theory, the advancement makes infrared once more viable for mobile device syncing, with room to grow: even the current technology can scale to 3Gbps, lead researcher Frank Deicke says, and it might jump to 10Gbps with enough work. Along with the usual refinements, most of the challenge in getting production hardware rests in persuading the Infrared Data Association to adopt Deicke's work as a standard. If that ever comes to pass, we may just break out our PalmPilot's infrared adapter to try it for old time's sake.
Fraunhofer black silicon could catch more energy from infrared light, go green with sulfur
Generating solar power from the infrared spectrum, or even nearby frequencies, has proven difficult in spite of a quarter of the Sun's energy passing through those wavelengths. The Fraunhofer Institute for Telecommunications may have jumped that hurdle to efficiency through sulfur -- one of the very materials that solar energy often helps eliminate. By irradiating ordinary silicon through femtosecond-level laser pulses within a sulfuric atmosphere, the technique melds sulfur with silicon and makes it easier for infrared light electrons to build into the frenzy needed for conducting electricity. The black-tinted silicon that results from the process is still in the early stages and needs improvements to automation and refinement to become a real product, but there's every intention of making that happen: Fraunhofer plans a spinoff to market finished laser systems for solar cell builders who want their own black silicon. If all goes well, the darker shade of solar panels could lead to a brighter future for clean energy.
Ski helmet charges iPods, iPhone and other mobile devices
A team of German researchers is working on technology that could let you ski all day without worrying about your smartphone battery, says a report in GlobalPost. Scientists from the Fraunhofer Institute in Berlin, TEXSYS and the Technical University in Berlin have created a solar helmet that charges your mobile device while you ski. The helmet has a curved solar panel skin, integrated headphones and a microphone so you can use your phone or mp3 player on the slopes. They've also designed a special set of gloves that can control your mobile device. Though it might not appeal to your casual, recreational skier, this solar system could be useful for adventurers who need extra juice for a long day mountaineering as well as mountain rescue teams who would appreciate the always-on communication.
DASH promises stutter free streaming video over LTE, hopes you don't care about quality
We've all been there: fire up a clip from YouTube or a movie on Netflix and things start out great. But, then, after just a few moments, that LTE connection starts to give up the ghost and suddenly you're faced with unbearable stuttering or a video that just dies mid stream. Researchers at the Fraunhofer Institute for Telecommunications are looking to solve that conundrum with DASH, or Dynamic Adaptive Streaming over HTTP. The idea is actually surprisingly simple -- files of different sizes and qualities will be available depending on signal strength and network load, and the stream will be able to seamlessly switch between them as these variables change. While this sounds like a win for both consumer and carriers, we're sure there are a few of you out there who just want the highest quality possible, even if that means waiting forever for that HD clip of the all accordion cover of Take On Me to buffer. Full PR is after the break.
Viatag NFC system pays parking lot fees with an RFID tag, saves lives
Paying for parking isn't exactly a fun experience, but Germany's Fraunhofer Institute is doing its best to make it slightly less painful, with Viatag -- an NFC system that allows you shell out your hard earned cash without even reaching for your wallet. The setup is relatively simple, consisting of a small RFID tag, compatible transceivers and a centralized database. Once attached to your car's windshield, the tag communicates with the transceivers installed within a given parking lot, alerting the system whenever your vehicle enters or leaves. An application running on the central server, meanwhile, keeps track of how much time you spend in the lot, and charges your debit card accordingly. Researchers have already installed Viatag at car parks in Essen, Duisburg and Munich, and are hoping to expand it to other locations. It might not be as sophisticated as some of the other automotive communications systems we've seen, but it could come in handy during those moments when you really don't feel like swearing at a parking meter. Cruise past the break for the full PR.
Ultra-thin handheld microscope could sniff out skin cancer, forged documents
It may not look like it, but that sleek black thing pictured above is actually a microscope. Designed by engineers at Germany's Fraunhofer Institute for Applied Optics and Precision Engineering IOF, this little guy boasts a 5.3mm optical length, rendering it slim enough to fit in the palm of your hand, yet powerful enough to deliver images at a scanner-like resolution of five micrometers, over a wide surface area. Fraunhofer's researchers achieved this balance by essentially tossing out the manual on traditional microscope design. Whereas most devices slowly scan areas and construct images on a piecemeal basis, this handheld uses several small imaging channels and a collection of tiny lenses to record equal sized fragments of a given surface. Unlike conventional scanner microscopes, all of these 300 x 300 square micrometer imaging channels are captured at the same time. With a single swipe, then, users can record 36 x 24 square mm shots of matchbox-sized objects, without even worrying about blurring the images with their shaky hands. The prototype is still two years away from going into production, but once it does, engineers say it could help doctors scan patients for skin cancer more easily, while also allowing bureaucrats to quickly confirm the authenticity of official documents. We can only imagine what it could do for Pac-Man. Full PR after the break.
German researchers prototype 6mm thick pico projector
Pico projectors just keep shrinking, and a new prototype developed at the Fraunhofer Institute for Applied Optics and Engineering is helping said shrinking along pretty strikingly. The team has developed a prototype pico which is just 6mm thick, making it the world's slimmest ever. Better yet, the projected image is 10 times brighter than a pico projector of its size would have previously been -- had it existed. The new lens on the projector is so small that it could potentially be integrated into smart phones without boosting size or weight. The new prototype is made of 45 red, green or blue microlenses, each with a 200 x 200 pixel LCD, inspired by a microlens array called a fly's eye condenser. The resulting resolution is nearly, but not quite, WVGA with 11 lumens of brightness. The prototype will be shown off at Nano Tech 2011 in Tokyo. [Image credit: Fraunhofer Institute]
'Trilobite' compound eye puts a Paleozoic spin on mobile camera design
Extinct marine arthropods make for great design references -- just ask Andreas Brückner. The Fraunhofer Institute of Applied Optics and Precision Engineering researcher has taken a cue from the trilobite in creating a 1.4mm thin "cluster eye" camera to take 221 images at 39 pixels per side to form a 700 x 550 (0.38 megapixel) composite. At this point, it's also capable of recording 13 frames per second for video, and with a size like that, if they can bump up the specs it could pave way for smaller camera components in mobile phones. Not anytime soon, of course, as it's still in the research state (and it's just one of many camera research projects out there). The next step for Brückner and company is shrinking the aforementioned design to 1mm thin (and up the video to 30fps), as well as 1.5mm variant with one megapixel resolution.
German researchers develop biotech sensor bracelet, disposable blood lab
Biochips -- flexible, disposable plastic circuits that "compute" via chemical reaction -- have been nearing reality for over a decade, but for obvious reasons we don't always pay attention. German research institute Fraunhofer IZM has just convinced us it's high time we did. This week, the organization announced that it's on the verge of creating a lab-on-a-chip that can diagnose deep vein thrombosis from a single drop of blood, as well as a wristband that can measure body temperature, skin moisture and electromagnetic radiation using plastic chips and sensors only micrometers thick. Impressive, yes, but the real news is the production process -- these gadgets can be printed in reels and sheets. The organization imagines the tools will be so cheap they'll be disposable; rather than wait for lab results, worried individuals will just take one out, test and toss to feel confident about their bloodwork, before hopefully going back to their normal lives.
Fraunhofer Institute's fruit checker device tracks optimum ripeness so you can stop sniffing those melons
Researchers at the Fraunhofer Institute have developed a small device that can be used to check the freshness of fruit, telling the interested parties whether it's ripe or not. Based on previous technologies which measure -- for example -- car emissions, the device measures the volatile gases emitted by the fruit and analyzes its makeup to determine the state of freshness. The team already has a working prototype, and sees the device, which would cost somewhere in the thousands of dollars range, as having widespread application for businesses that supply food to grocery stores. So far the device has only successfully been used to test the freshness of fruit, but researchers see possible future applications in testing meat as well.
Tiny, printable batteries promise to change the face of obnoxious greeting cards forever
Researchers at the Fraunhofer Research Institution for Electronic Nano Systems ENAS in Chemnitz led by Prof. Dr. Reinhard Baumann have unveiled tiny, printable batteries that they hope to put into production for pennies apiece. The new battery prototype is primarily composed of a zinc anode and a manganese cathode that can be screen printed and covered with a non-printed template cover. Each mercury-free battery weighs less than one gram, and can individually produce about 1.5 volts of electricity. By placing several batteries side by side, however, up to 6 volts can be generated. The institute has already produced these little power houses in the lab, and hopes to see them into production by the end of the year. The batteries have a relatively short lifespan, making them suitable for applications such as powering greeting cards. All we can say is that this battery would have made the card we got two years ago that sang "Word Up" much, much awesomer. [Via Physorg]
OLED mini projector prototype for mobile phones using a series of lenses developed
Researchers at the Fraunhofer Institute -- partnered with project HYPOLED -- have created an OLED mini projector prototype for mobile phones. Unlike many previous iterations of similar technologies, this new prototype doesn't need an additional illumination system, instead relying on a lens system to project images produced by an OLED onto a screen or wall -- making it both smaller and more energy efficient. The prototype currently displays a monochrome image with a brightness of 10,000 candelas per square meter, and color images with a brightness of about half of that. The lenses are also made of glass at this point, though cheaper and simpler plastic ones are in the works. No word on when we might see these prototypes hitting the streets in actual projector phones, though.[Via Gizmag]
Underwater robot has sense of touch, class and style
At the Fraunhofer Institute in Bremen, Germany, a group of researchers, in conjunction with the German Research Center for Artificial Intelligence DFKI, is developing an underwater robot with a sense of touch. The octopus-esque robot is equipped with a strain gauge which triggers electrical resistance changes when an obstacle is encountered. The strain gauges -- which are printed onto the robot -- which are ten micrometers wide (about half the width of a human hair), are made up of atomized nanoparticles, and are extremely sensitive. The researchers intend for the robot to be able to distinguish between actual obstacles and water currents. The robot's first stop will be a public trade show at the end of May in Nuremberg, after which it will presumably make it's way to the dark depths of the sea to meet up with Captain Nemo and the giant squid.
Fraunhofer's 3D dashboard prototype
The sheer amount of technology companies are willing to throw at your car's dashboard is amazing (well, maybe not your car -- after all, you're still driving a '76 Gremlin). Taking things up a notch, the folks at Fraunhofer have developed a dash that displays your location and the surrounding area in 3D, in real time. The system uses cameras to keep track of the location of your eyes, so the depth imaging effect can be achieved without using those funny glasses. In addition to the GPS, the dashboard only displays the information that is most relevant to the driver at any time -- fuel gauge, tire pressure, route information or the title of the song can be displayed, depending on user preferences. It's only a prototype at this point -- be sure to check it out when you hit CeBIT in Hanover this March.[Via The Raw Feed]
Fraunhofer takes a stab at non-exploding lithium-ion batteries
It's hardly the only one working on making lithium-ion batteries a little less likely to blow up in your face, but the prolific folks at Fraunhofer Institute seem to think that they've come up with a solid contender for your future laptop or cellphone, and they're now set to take the wraps off it at the Hannover Messe conference later this month. The key to their solution, it seems, is the use of a non-flammable polymer electrolyte instead of the liquid electrolyte now commonly used in lithium-ion batteries. While that switch cuts down on the explosiveness, it also introduced a fair number of challenges, not the least of which is the fact that polymer becomes less conductive as it gets more solid. Fraunhofer's apparently made some significant progress on that front, however, and while they're still not completely satisfied with the conductivity, they say the batteries could be ready for commercial use in three to five years. They also, not surprisingly, see no end to the uses for 'em, saying that they could not only wind up in laptops and cellphones, but power tools, lawnmowers, and potentially even cars.[Thanks, Mademoiselle Y]
Fraunhofer's Surround Vision lets projectors get curvy
Those prolific folks at the Fraunhofer Institute recently took the wraps off yet another invention of theirs, this one promising to let projectors do things they've never done before (or at least let 'em do it more easily). More specifically, its "Surround Vision" software will automatically calibrate projectors to allow for images to be projected on surfaces of any shape with "pixel-precise accuracy". What's more, according to Gizmag, the system can apparently be used "in principle" with any type of projector. While it seems unlikely that many folks will be reworking their home theaters to take advantage of the system, the Fraunhofer folk see no shortage of other applications for the technology, including trade show booths, theme parks, simulators, and planitariums, to name a few.
Body powered circuits developed by Fraunhofer Institute
Our favorite German researchers over at the Fraunhofer Institute have developed "entire electronic systems" capable of operating battery-free from body heat alone. The picture above shows a wireless transmitter powered by the human hand. The 200 millivolts required to drive the device is supplied by a thermoelectric generator (TEG) which extracts electrical energy from hot and a cold temperature differentials of just a few degrees Celsius. Of course, the application processor alone in modern handhelds requires about 1W to operate so 2mW is a long way off from powering our portable electronics. Still, progress is progress.
