Our 1997-era selves would pass away with envy right about now. Fraunhofer has actually developed a brand-new generation of infrared transceiver that could transfer information at 1Gbps, or well above anything that our vintage PDAs can manage. While the rate is nothing brand-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 reliable sufficient to fit into a little module whose transceiver is as big as a “kid’s fingernail.” In idea, the improvement makes infrared once more viable for mobile device syncing, with space to expand: also the existing modern technology can scale to 3Gbps, lead specialist Frank Deicke says, and it could leap to 10Gbps with enough work. Along with the usual refinements, most of the difficulty in getting production equipment rests in persuading the Infrared Data Association to follow Deicke’s work as a standard. If that ever before comes to pass, we may simply break out our PalmPilot’s infrared adapter to try it for old time’s sake.

Generating solar energy from infrared spectrum, or also close-by frequencies, has shown tough in spite of a quarter of Sun’s energy passing through those wavelengths. Fraunhofer Institute for Telecommunications might have jumped that hurdle to efficiency with sulfur– one of the very materials that solar power commonly helps do away with. By irradiating average silicon with femtosecond-level laser rhythms within a sulfuric environment, technique melds sulfur with silicon and makes it simpler for infrared light electrons to develop into the frenzy needed for carrying out electricity. The black-tinted silicon that results from the procedure is still in the early stages and needs enhancements to automation and refinement to come to be a real product, but there’s every objective of making that happen: Fraunhofer prepares a spinoff to market completed laser systems for solar cell builders who prefer their very own black silicon. If all works out, darker shade of solar panels might cause a brighter future for clean energy.

Infrared telescope can pick out the atmosphere on distant planets, smell what the aliens are smelling
Astronomers in Chile utilizing the European Southern Observatory’s Very Sizable Telescope are now able to evaluate the atmosphere on faraway planet Tau Bootis b. Utilizing CRIRES, a supercooled infrared spectrograph bolted to the ‘scope, the team was able to evaluate the dimension of the exoplanet– and for the very first time, take a reading of the atmosphere while not in transit. Historically, the only time specialists have been able to carry out atmospheric analysis is throughout the transit of its close-by star, which imprints the qualities of the atmosphere onto the light. The group located that Tau Bootis b is around six times the size of Jupiter, but its air is so thick with Carbon Monoxide that we’ll need to look elsewhere to organize that expedition to the stars.

Question by Pete S: What can I use an infrared LED for, in terms of robotics or electronics?
Answer by Bob B
Infrared LEDs are frequently used for communications. A TV remote control is one typical example.
What do you think? Answer below!
NASA’s Wide-field Infrared Survey Explorer (WISE) mission began mapping the sky in 2010, but after collecting more than 15 trillion bytes of data it took more than a little time to process the information. That task complete, NASA has now released a new atlas and catalog covering the more than half a billion celestial objects mapped by the project — some of which were captured for the very first time. Over 2.7 million images taken at four infrared wavelengths of light were collected for the project, which were then condensed down to the 80,000 images available in the new atlas. Even prior to the release of the new imagery, the WISE mission yielded insights, offering the first glimpses of a class of failed stars known as Y-dwarfs, as…

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.

Infra-Red Satellite Imaging Reveals Buried Egyptian City, Final Resting Place Of The Ark Of The Covenant! (Per Indiana Jones)
Infra-red satellite imaging of Egypt has revealed a buried city near San El Hagar with over 17 pyramids, 1,000 tombs and 3,000 other buildings. It’s the ancient city of Tanis, and it’s where the Ark of the Covenant is buried (provided you believe Raiders of the Lost Ark, but not past the point where Indy actually finds it, the Nazi’s get all f***ed up after opening it, and it winds up in a crate in some nondescript government warehouse). Sounds legit to me!
The team analysed images from satellites orbiting 700km above the earth, equipped with cameras so powerful they can pin-point objects less than 1m in diameter on the earth’s surface.
Infra-red imaging was used to highlight different materials under the surface.
Ancient Egyptians built their houses and structures out of mud brick, which is much denser than the soil that surrounds it, so the shapes of houses, temples and tombs can be seen.
So like, is looting still frowned upon? Hey — I don’t even need the ark, I’d settle for a mummified cat and a jarful of organ jerky. Just a little something for my foyer to let visitors know I’m cultured. “Would you settle for a paperback copy of ‘The Book of the Dead’ and a cartouche necklace that reads ‘Geekologie Writer’?” SOLD!

Thanks to Paul E, not to be confused with Wall E, who I’d beat to pieces with a shovel.
It just keeps getting harder for America’s enemies to hide from the technological marvel that is the modern US military. A new ground fire acquisition system (GFAS), coming to Apache Attack helicopters next spring, uses infrared sensors to detect muzzle flashes from small arms fire and pinpoint enemy positions to within five meters. Before the sound would have a chance to reach current acoustics-based sensors the source of the shot pops up on the targeting computer, is sent back to commanders in the Operations Center, relayed to ground troops, and fed to other aircraft — by the time they’re able to pull the trigger again combatants may already be on the wrong side of a Hellfire missile. The new system will make spotting opposing forces easier and keep pilots as safe as they can be — at least until missions can be flown from the comfort of their couch.
