Researchers working on thermal cloak, Predators trill their disapproval
Slathering yourself with mud to avoid head-hunting aliens is great and all, but it ain't exactly the paragon of good personal hygiene. Fortunately, researchers have concocted a cleaner and less cakey defense against Predators that's more likely to be mom approved. Fresh on the heels of the microwave invisibility project at the University of Texas at Austin, French researchers have found a way to make a cloak that can hide a subject from thermal imaging devices. The concept uses alternating materials with varying rates of diffusion to move heat around and create a thermally invisible region. Conversely, the technique can be used to concentrate heat in one spot so it gets hot rapidly. Although it doesn't quite have the wow factor of Cornell's invisibility project, the thermal research may prove to be more practical because it also can be used to manage heat and improve cooling in components such as computer chips. Of course, the question now is, can it be used to cloak an entire tank?
Samsung Galaxy Tab 7.7 review (Verizon Wireless LTE)
Samsung Galaxy Tab 7.7 review (international edition) Verizon Galaxy Tab 7.7 with LTE hands-on Samsung Galaxy Tab 7.0 Plus reviewSamsung's Galaxy Tab series boasts seven distinct models. Throw in all of the variants of each one -- LTE, WiFi, WiMAX and even the Galaxy Note 10.1 if you want to be picky -- and all of a sudden the number of tablets produced by the Korean electronics giant over the past sixteen months shoots up to exceed twenty. In a vast sea of incredibly similar-looking Android slates, there's one model that dares to be different: the Galaxy Tab 7.7, an oddly sized tablet with a stunning Super AMOLED Plus display.Last month, we were given the opportunity to review the global version, and definitely liked what we saw. It's an understatement, then, to say that we were ecstatic to give Verizon's LTE version a run for its money (which, at $500 with a two-year commitment and $700 without, is a lot). What did Big Red choose to tweak? How's the battery life once you factor in that next-gen network? These answers and more are coming your way after the break.
Infrared images show new iPad screen running warm
Remember when we said there were reports that the new iPad was running hot? Thanks to the folks at Tweakers.net, we now have some quantitative measurements to support these observations. The Dutch website ran a GLBenchmark test on the new iPad and the iPad 2 and compared the infrared profiles of each device. According to their measurements, the hottest part of the new iPad reached 33.6 degrees Celsius (92.5 degrees Fahrenheit), while the iPad 2 ran at a cooler 23.8 degrees Celsius (74.8 degrees Fahrenheit). You can see the differences in the image above where the new iPad is on the left and the iPad 2 on the right. The team at Tweakers attributed this difference to the quad-core GPU of the new iPad. When its being stressed by a benchmark test, the GPU will generate extra heat that'll raise the temperature of the device. Though high, the levels measured by Tweakers were still within the operating limits of the device which are 32 degrees to 95 degrees Fahrenheit (0 degrees to 35 degrees Celsius). Even if more reports corroborate these results, this excess heat issue won't be a problem for most people. If you game a lot and live in a warm climate, you might have to watch your usage, but most people don't stress their devices with heavy gaming. Under normal usage, the iPad might get slightly warm, but it shouldn't climb to the point where the device regularly shuts down. [Via Engadget and MacRumors]
Switched On: Extra Sensory Perception
Each week Ross Rubin contributes Switched On, a column about consumer technology. At Intel's CES 2012 press conference, the giant chipmaker justified calling thin notebook PCs "ultrabooks" by noting how the devices would increasingly be characterized by more than their thinness. The integration of sensors has become so core to the modern smartphone experience that their absence would make using such devices untenable.Most of that differentiation was based on plans to integrate the kinds of sensors that have become commonplace in smartphones and tablets, sensors that can detect location, motion, orientation and proximity. The integration of sensors has become so core to the modern smartphone experience that their absence would make using such devices untenable. Imagine if we had to manually reorient a display every time we wanted to play a game or take a photo or if we had to avoid activating a button with our cheeks when holding a phone against them.But as Switched On discussed in taking on how screen size affects form factors, what is a limitation of form factor today may not hold true tomorrow. Already, of course, smartphones can tap into remote intelligence for applications such as remote camera viewing or unlocking of doors via services from home security companies such as ADT and Vivint. From around the world, you can even remotely start a vehicle using the Viper SmartStart app. But there are increasing opportunities for smartphones to act on information from sensors that are not embedded into their shells.
Neonode zForce uses infrared LEDs to measure pressure, replace capacitive touch (hands-on)
Smartphone fanatics may recall the Neonode N2 -- a rather unique recall-plagued feature phone that ultimately resulted in the demise of the company's handset arm. Neonode is still a major player in the portable device market, but may be more familiar to OEMs that employ its infrared LED-based touch technology, rather than consumers that utilize it in e-readers, with tablets soon joining the mix. zForce offers several advantages over its capacitive-based counterparts -- it's incredibly responsive and accurate, and can now measure the intensity (or pressure) of your touch, and not just position. There's also a built-in proximity sensor that can be added to any device for a few pennies, which is considerably less than traditional offerings. However, because Neonode uses an array of infrared LEDs and photodiodes, a raised bezel is required to accommodate the additional hardware, making it impossible to integrate a flush display.We went hands-on with an updated smartphone-sized embed of the company's zForce technology that not only works with any object, such as a finger, pen or a paint brush, but also recognizes both the pressure of your implement and also its size, so a larger paint brush has broader strokes than a smaller one, for example. Because the device can operate at 500Hz all the way up to 1,000Hz (refreshing 1,000 times per second), it appears to be incredibly responsive, with an almost unnoticeable delay between the time you touch the pad and when your input is displayed on the screen. A second demo unit, called Stargate, offers dual-layer touch with support for 3D control -- you can literally reach inside the unit to manipulate an object. There's no word on when this latest tech will make its way into devices, or how exactly we'll see it used, but you really need to see it in action to get a feel for how it works -- jump past the break for our video hands-on.%Gallery-149305%
Insert Coin: Prototype peripherals incorporate no moving parts, multitouch functionality and freaking lasers
In Insert Coin, we look at an exciting new tech project that requires funding before it can hit production. If you'd like to pitch a project, please send us a tip with "Insert Coin" as the subject line. When in doubt, strip out the moving parts and see what you wind up with. This is the idea inventor Jason Giddings is following as he turns to Kickstarter to help fund the prototype creation for a glass keyboard and mouse, both sporting multitouch functionality. The design uses the same biometric systems that currently capture fingerprints on assorted trackpads and keyboards, and uses a technique known as Frustrated Total Internal Reflection -- which incorporates a series of LEDs on the bottom of a device -- to bounce infrared light beams around the inside of the glass. This process is interrupted when a finger touches the glass, wherein a simple embedded camera captures the event, processes where the keystroke, mouse click or gesture took place and relays the signal to the computer.
Add lasers to a tennis ball, drive your dog crazy (video)
It's a "programmable disco ball," a "cat toy for humans," and a "personal laser light show," all rolled into one. That's how one Matt Leone describes his latest creation, aptly known as the Laser Ball. To realize his dream, Leone drilled a set of holes into a garden variety tennis ball, and inserted about 14 laser diodes, each with an attached strip of diffraction grating. Said diodes were then synced up with an Arduino-equipped Teensy microcontroller nestled within the ball, alongside a rechargeable battery. As a cherry on top of this DIY sundae, Leone then incorporated an infrared remote package from Adafruit, allowing him to remotely jump start his next house party. The result is a cyborg-like ball that makes any LED cube look... square. Check it out for yourself, in the video after the break.
Scientists make magic auto-origami using ink and light (video)
We've seen nano-origami and robo-origami, but nothing quite as rapid and simple as this. Researchers at North Carolina State University have figured out how to neatly fold plastic using infrared light and an inkjet printer. Deep black lines are printed onto the plastic sheets, which then absorb the light and cause the material to fold without anyone having to touch it. The wider the line, the greater the angle of each fold, so it's possible to set, say, a 90-degree bend for a cube or 120 degrees for a pyramid. What's more, by giving the lines different patterns, folds can be made to work in specific directions, potentially producing the most perfect, most hygienic bento box that's ever contained your lunch. Click past the break to watch the folding unfold.
Your iPhone 4S's proximity sensor's working overtime -- thank Siri (video)
As far as assistants go, Siri can be rather demanding. In fact, she apparently requires that your iPhone 4S's proximity sensor be on whenever the handset's screen is activated. That's the conclusion iFixit arrived at, upon discovering that, unlike previous generations which flip on the sensor upon firing up a phone call or Skype conversation, the 4S kicks on the infrared detectors whenever the screen turns on. The change would allow Siri to detect just how close your face is as you speak to her without the handset pressed up against your face. More details in the video after the break.
Griffin's Beacon universal remote control system now available for Android, ships for $70
It's been quite a while since we got our hands on Griffin's Beacon universal remote control, way back at CES. The IR converter has since hit the market for iOS users, but the Android community, until recently, had been left in the dark. That changed yesterday, however, when Griffin announced that its wire-free system is now available for Google-powered handsets and tablets. The transmitter, fueled by a quartet of AA batteries, converts an Android device's Bluetooth signal into infrared and sends out commands to your TV, DVD or Blu-ray player, effectively allowing users to place it anywhere around their home entertainment system. The remote control functions are handled by Dijit's customized app, where you'll be able to browse, search and call up TV shows, using the integrated guide. The app, like its iOS counterpart, is available for free, but the system itself will set you back about $70.

Texas Sheriff's office receives weaponizable drone, alarms local news station
Ready to supersize your favorite RC helicopter and bullseye some perps with an aerial bean bag launcher? The Sheriff's office in Montgomery County, Texas is, and it's really freaking out the local news. KPRC Local 2 News feverishly asks if the Sheriff's new unmanned Shadowhawk helicopter is a safety asset, or a privacy violation -- we just think it's awesome. Built and sold by Vanguard Defense Industries, this wireless whirlybird comes equipped with a remote video camera, an infrared heat-seeking device and an onboard GPS. It's also capable of carrying weapons, although the Sheriff said that there were no plans to weaponize the UAV. The 50-pound chopper is FAA approved to help track down criminals on the run or assist swat teams in a standoff -- a blessing that should keep this police drone from being grounded.

SideBySide makes tiny projectors fun again (video)
Kids these days just don't get thrilled by tiny projectors the way they used to. Disney Research is hoping to address the problem with its new SideBySide prototype, a pico projector that interacts with images projected nearby. The device outputs both visible and infrared light, while a built-in sensor detects the latter, allowing it to react to the image. The team showed off a handful of applications for the technology, including a few games, drag and drop file sharing and the ability to change perspectives on a 3D model. Non-interactive video after the jump.
Desk Pets' TankBot rolls out with Android and iOS support, is the tiny racer in your hand
Lonely and living in the city, but don't have the patience or maturity for Man's Best Friend? Well, you could always take a TankBot under your wing. Desk Pets' palm-sized four-wheeler first whirred into our hands earlier this year at the International Toy Fair, promising a variety of play modes and iOS control. Now, the team behind the roving gizmo has finally released it to retailers' shelves, tacking on a $25 price tag and adding Android compatibility. The mini-bot operates in a trio of configurations: an autonomous mode that makes use of its infrared sensors to navigate obstacles, a free-roaming option that'll have it wandering aimlessly and, most importantly, a free mobile app that puts dual joystick control on your Apple device's screen or universal remote (connected via headphone jack) for steering on an Android phone. Don't expect to squeeze hours of fun out of this little tchotchke, though, as its retractable USB port only gets you about 15 minutes of gee whizzery. Skip past the break to watch a video demo of the lil' guy en vivo.
Tiny infrared LEDs could find a home in ultra-thin multitouch screens
A company called Osram Opto Semiconductors has created a new infrared LED that can be used in conjunction with detectors to create ultra-thin touchscreens. We've seen infrared used in touchscreens before, most notably in Microsoft's Surface and recent e-readers from Barnes & Noble and Kobo. But, Osram's solution is complex enough to work in a multitouch tablet, while being as space-saving zForce. At only 0.45mm tall the diodes and sensors can easily be crammed into a bezel around a screen and sip just 35mW during regular use. Now the company just has to convince someone to put the tiny IREDs in their products.
Volvo unveils Concept You luxury sedan, dripping with touchscreens (video)
The Frankfurt Motor Show is underway in Germany, where Volvo has just taken the wraps off the Concept You -- a new luxury sedan that features some pretty nifty, touch-based controls. Directly behind the car's steering wheel lies a monitor that digitally displays your basic driving information, including speed and a map of your trajectory. The wheel also features some sensor enhanced panels, which you can use to adjust your radio or cruise control settings. A touch interface on the center console, meanwhile, uses an infrared sensor to pick up on any hand or eye movements before activating to bring up the system's infotainment control mode, which boasts an unreleased FreshAir subwoofer from Alpine. From here, you can surf the web, swipe through radio stations, check for safety alerts or control your air conditioning, using only your fingers or customized gestures. Plus, there's an extra touchscreen placed between the two rear seats, meaning your kids won't be left out of the action, either. Cruise past the break for an exclusive video of the Concept You's so-called smart pad technology, along with the full PR.
Zero1 VooMote Zapper remote control for iOS hands-on (video)
Are you one of those old-school types who still watches TV programs on an actual television? Then you probably also own one or fifteen of those cordless channel changer contraptions -- you know, the kind that use AA batteries and magic beams of light to command station and volume adjustments. Well, set down the remote, lean back in that oversized plastic-covered velvet sofa, and get ready to toss out your last pair of alkalines. Zero1's new VooMote Zapper remote module has been making the rounds at IFA, letting you use any iOS device as a universal remote. Sure, the concept itself isn't new -- there have been other iOS-integrated remotes -- but the Zapper is small, relatively inexpensive, and interfaces quite nicely with your iPhone, iPad, or iPod touch. Your programmed selections are stored on the Zapper itself, so you can easily use it with multiple iOS devices. The $70 device can be matched with identically colored cases ($20 and up), and also includes rather comprehensive TV Guide functionality, enabling you to see local programming, watch previews of unfamiliar content, and send an infrared signal to your TV to launch a program -- during its scheduled airing time, of course. We took a look at the app / itsy bitsy hardware combo, and it seemed to work well, with an easy setup process (codes for nearly every device come preloaded) and fast response time. VooMote reps said the device has a range of 25 feet, which is more than plenty for our tiny apartment configs, but may not suffice in some stadium-style media rooms. At the end of the day, it's really just a (very) elegant touchscreen universal remote solution, so we'll leave it at that. Jump past the break to see the Zapper in action.%Gallery-132608%
Zero1.tv's Voomote Zapper brings remote-controlled universality to iOS users
Back in July, we caught a glimpse of the Voomote One -- Zero1.tv's universal remote adapter for iPhone and iPod Touch users. Now, the company has just announced a slimmer, iPad compatible successor to its bulky peripheral, with the Voomote Zapper. Slated to debut at IFA later today, this paperclip-sized dongle attaches to your iDevice's 30-pin connector, allowing you to remotely control any A / V gadget with the help of Zero1.tv's free and customizable iOS app. The Zapper's Room Control feature also lets you catalog all your infrared devices by location, while controlling multiple systems with a single button, thanks to its One View function. Its iPad-optimized TV Guide, meanwhile, allows you to fire up your favorite shows with even greater ease, using the app's graphically-displayed programming schedules. No word yet on pricing or availability, but you can zap your way past the break for the full press release.
Wrist sensor turns the back of your hand into a meaty haptic interface (video)
We're all intimately familiar with the backs of our hands, so why not use them as a haptic interface to control our gadgets? That's the idea behind the device pictured above -- a nifty little wrist sensor that turns your paw into a flesh-toned trackpad. Designed by Kei Nakatsuma, a PhD student at the University of Tokyo, this contraption employs infrared sensors to track a user's finger as it moves across the back of a hand. These movements are mirrored on a wristwatch-like display, thanks to seven IR detectors and a set of piezoelectric sensors, effectively turning any digit into an organic stylus or mouse. Nakatsuma, who unveiled his work at this week's SIGGRAPH, says his creation can't handle the more complicated, pinching or rotating gestures you could manipulate on most smartphone touchscreens and acknowledges that the screen can be difficult to read in direct sunlight. But the underlying technology could pave the way for similarly handy designs, while allowing users to interact with their gadgets without having to constantly glance at their screens, or go fishing in their pockets. Feel your way past the break to see a video of the device in action.
Light Blue Optics touch interface pico projector passes through the FCC
Last time we saw Light Blue Optics' Light Touch, it was deep in the bowels of CES, where we got to play with its touch-sensitive projections. Well, the little laser pico projector has finally made its way from that dark trade show corner into the bright lights of the FCC. It still turns any flat area into a WVGA touchscreen using holographic laser projection (HLP) and infrared sensors, only now it's more finger friendly and supports multi-touch gestures. It also has a 3.5mm headphone jack and a single mono speaker so you aren't surface computing in silence, and there are composite video and micro-USB ports for pulling content from other devices. Of course, the Light Touch still only projects a 10.1-inch image, so it won't be turning your wall into a touchscreen. But, it should do just fine turning a tray table, desk, or perhaps even the nearest person planking into one.
Sony's S1 and S2 tablets pose for the cameras again, show off more angles (video)
Sony's S1 and S2 Honeycomb tablets have been very coy in front of the cameras since their initial unveiling. Aside from two visually pleasing short films and a tease of a hands-on, we haven't seen much of them since -- or any specific release details, for that matter. The former's changed at least, however, thanks to Notebook Italia. The site managed to handle the duo long enough in front of a lens to capture a bevy of snapshots, along with a short video of the S1 running PlayStation Suite. If you've been anxious to get a better look you'll find the S1 clip past the break, and all of the photos by hitting the source link below.
