    You may remember seeing Orbitsound's T12 iPod dock / soundbar pop up in our summer buyer's guide. Today, the firm's just unveiled the latest in its product family: the Orbitsound T9. As you'll see, it's a very similar deal, but with an obvious difference -- its size. At 300mm (about 12") across, it's almost exactly half the length of its bigger brother (605mm) -- but not everything is a straight cut down the middle. Power-wise, this diminutive dock has a power output of 140W RMS (split 80 on the subwoofer, 35 on the front speakers and 25 on the sides,) and carries the same in- and output options. That means optical, line (phono and 3.5mm) and an iDevice connector going in, and a composite video (for piping those movies on your iPhone to your telly) in the other direction. The included subwoofer helps the device perform the dual roles of iPod dock, and TV soundbar. It's launching in mid-July in UK retailers, and internationally online for £200 / $249. Luckily, we managed to get our hands on one of the first production models, and took it for a spin, so boogie on past the break for our impressions.%Gallery-158189%

  • Optical cables for Thunderbolt coming in 2012

    The cabling for Apple and Intel's next-generation peripheral interconnect will be getting an upgrade this year, says IDG. Thunderbolt optical cables will be shipping in 2012, according to Intel; current cabling for TB is all copper-based. The PCI-based Thunderbolt technology has always included optical cabling in its roadmap, but the costs of fiber versus copper and the development lead time meant that the initial implementation didn't include the optical option. Mac Thunderbolt ports and peripherals, fortunately, should be compatible with both types of cabling; swapping out one for the other should be straightforward for the most part. The only catch with optical TB cabling is that bus-powered devices (like Elgato's new Thunderbolt SSD drive) will probably require a power injector or standalone power supply. The optical cable's extended run length (multiple times the six-meter copper TB cable limit) means that power can't be dependably run through it. Thunderbolt peripherals have been thin on the ground since the first TB-equipped Mac models were announced early in 2011, but more and more are starting to arrive now. Sonnet's ExpressCard adapter allows for multiple interface options for TB machines, including FireWire 800 and eSATA.

  • Optical computing could benefit from new 'whispering gallery' fiber

    It's a spooky feature of Grand Central Station that if you whisper something against the wall, your voice can resonate around the perimeter of the building and sneak up on you from behind. The same 'whispering gallery' principle is crucial to next-gen optical computing: light signals have to be sent on extremely circuitous journeys through 'microresonators', which temporarily bottle up the beams and thereby serve as memory. So far, microresonators have generally been made from silicon wafers etched with the a long series of loops. However, even the most precise etching leaves imperfections, which quickly cause the signal to lose its strength and fade away. Now, researchers at OFS Laboratories in Somerset, N. J., have come up with a different type of microresonator that could potentially hold onto light 100 times longer. The new technology diverts light onto a stretch of optic fiber that has been specially manufactured with tiny step-changes in its diameter. When the signal hits this abrupt change, it reverses and goes back the opposite way -- and, if it hits another diameter change, it will effectively enter a whispering gallery inside the fiber, bouncing up and down with only minor attenuation. The OFS scientists claim their microresonator could appear in "specialized devices" in just two or three years, which is good to hear, because electronics is starting to get old.

  • MIT slinks into a cafe, orders a side of photonic chips on silicon

    Whiz-kids the world over have been making significant progress on the development of photonic chips -- devices that "use light beams instead of electrons to carry out their computational tasks." But now, MIT has taken the next major leap, filling in "a crucial piece of the puzzle" that just might allow for the creation of photonic chips on the standard silicon material that underlies most of today's electronics. Today, data can travel via light beams shot over through optical fibers, and once it arrives, it's "converted into electronic form, processed through electronic circuits and then converted back to light using a laser." What a waste. If MIT's research bears fruit, the resulting product could nix those extra steps, allowing the light signal to be processed directly. Caroline Ross, the Toyota Professor of Materials Science and Engineering at MIT, calls it a diode for light; to construct it, researchers had to locate a material that was both transparent and magnetic. In other words, a material that only exists in the Chamber of Secrets. Hit the source link for the rest of the tale.

    You may recall, back at CES, we got our hands on LG's LSM-100 mouse scanner and were able to try it out for ourselves. Well it appears that you may have that same opportunity soon. The company has announced that it will be "opening a new era for scanners" at IFA in a few days with its mouse that boasts a built-in scanner. Simply by holding the Smart Scan button, you'll be able to save or drag and drop scanned images as large as A3 paper size in a variety of formats -- PNG, JPEG, TIFF, and PDF, just to name a few -- by swiping the mouse over it. If that wasn't enough to entice you, the peripheral also features Optical Character Recognition that converts text from said images into an editable Word document. Perhaps lost in all this is the fully functioning mouse bit... which you'll probably need as well. No word yet on pricing or availability, but hopefully soon, you'll have room on your desk for one of these. Update: Apparently this bad boy is already available the UK for £89.98 (around $148), via the coverage link below. Also, we added a promo video from the folks at LG showing the peripheral in action -- which you can check out after the break. [Thanks to everyone who sent this in]

  • Nano-structured glass creates new type of computer memory

    We've sure come a long way since frying ants with a magnifying glass. Researchers at the University of Southampton used nano-structures to create millimeter-sized "monolithic glass space-variant polarization converters," which ultimately changes the way light travels through and is stored in glass. These "whirlpools" of light data can be read like information stored in optical fibers -- allowing for "more precise laser material processing, optical manipulation of atom-sized objects, ultra-high resolution imaging and potentially, table-top particle accelerators." (Does that mean we all get one of these on our desks?) This new five dimensional approach is reusable, twenty times cheaper and more compact compared to old methods of microscopy using a spatial light modulator, making it a win-win.

    The trouble with pesky Photon, at least as far as ultra-fast optical computing is concerned, is that he keeps coming back. If a data-carrying beam of light collides with reflections bouncing around between the components of a chip, it can suffer enough interference to make people yearn for the good old days of electrons. What's needed is the optical equivalent of a diode, which only allows light to pass one way, and that's exactly what researchers at Caltech and the University of California claim to have developed. As you'll see in the photo after the break, their metallic-silicon optical waveguide allows light to travel smoothly from left to right, but it breaks up and dissipates any photons traveling in the opposite direction. This is all good, because there's no point having futuristic 50Gbps optical interconnects if our CPUs lag behind. Light up the source link for a fuller explanation.

  • Razer totes Hydra sticks and 6400dpi dual-sensor mice to E3 2011, we go hands-on

    Razer's Sixense electromagnetic orb threw around plenty of intradimensional portals at CES, but sadly the company wouldn't let us play. Today at E3 2011, however, we were finally handed the reins. Those twin sticks are impressively responsive and accurate in the specially-made Sixense levels for Portal 2, and it's a heck of a lot of fun to physically stretch out blocks, reposition portals with a twist of the wrist and physically throw objects through the air. However, we got the impression that outside of games particularly designed to work with the sticks, it might be a different story. Waving the right stick around works pretty adequately for controlling the mouse cursor, but when we exited out to Windows, the sticks didn't work -- apparently, controls have to be mapped separately in a desktop client to work with the OS and other games or programs. We don't think many PC gamers will mind the six-foot range and wired tether here, but it does restrict those hoping to kick back with a game on the big screen. %Gallery-125856% We also got to try Razer's new "4G" dual-sensor technology, which will be rolling out to new Mamba and Imperator gaming mice right away -- it pairs a laser sensor and an optical sensor for more precision when lifting mice off a surface for advanced first-person shooter mousing techniques, not to mention 6400dpi tracking. We took it for a spin with a handy Razer Mamba, and we immediately fell in love -- whether we flung the mouse around haphazardly, furiously swiped it across the mousepad or simply tried for a quick headshot, it kept up with us. The cursor does creep if you lift and drop very rapidly, though, and without an original Mamba to compare with, it's hard to say just how much better it was. Thankfully, that won't be much of a factor in your purchasing decision: you'll pay the exact same $130 for the Mamba or $80 for the Imperator when they hit shelves this month. PR after the break. Update: Razer points out that you can in fact use the controller in Windows, enabling mouse movement and toggling the cursor with button 4, and left and right clicking with the right trigger and button 1.

    Ever seen a display like the one on the left? That's long been a pesky phenomenon -- known as "head-lighting" -- with many LED edge-lit LCD panels, and 3M's new Uniformity Tape wants to make sure it won't be around for much longer. Basically, the tape sticks onto an LCD's internal light guide, and its printed-on optical pattern disperses each LED's light path at wider angles. This allows for up to three times the distance between each LED, while still maintaining an even all-around brightness level across the panel. There are other benefits to this as well considering future LCD panels could use fewer LEDs -- cutting manufacturing costs, and raising eco-friendliness. Hopefully the tape actually ends up working as well as the photo illustrates, but for now, you can view the full press release by clicking past the break.

  • 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.

  • Researchers create two 100 terabit per second optical connections, dare us to torrent something

    Even a woman with a 40 Gbps internet connection might feel a twinge of jealousy at this news -- Japan has successfully tested two separate 100 terabit per second data links that use a single optical fiber to carry their loads. New Scientist reports that NEC scholars stuffed the light from 370 lasers into 165 kilometers of fiber to achieve a speed of 101.7 Tbps, while NICT researchers set a new record of 109 Tbps using a special fiber with seven cores to manage the trick. We imagine that Alcatel-Lucent and NTT aren't sitting still. Not that we really care who has the fastest fiber... just so long as one end leads to our house.

    Are you tired of waking up to the same old semiconductor-based solar array? Do you yearn for a change? We know you do and, thanks again to the wonder and mystery of magnetic fields (they're not just for stopping speech anymore), there's a new day dawning. University of Michigan scientists were shooting lasers at glass, as they do, and made a remarkable discovery: light passing through a non-conductive surface like glass generates impressive magnetic effects – up to 100 million times greater than expected. The resulting magnetic force could replace the electric effect exploited by current technology, paving the way for "optical batteries." Though different from the Wysips transparent photovoltaic cell, the technology could have similar applications and may render obsolete those massive solar farms. No need to worry, though -- your stylish solar backpack is as fly as it ever was.

    We've seen many a theoretical demonstration of lightning-quick networks, but most use some rather special purpose hardware -- like lasers and such that your average ISP doesn't have hanging around. However, this new benchmark of 448Gbps is a little more impressive because it was achieved on commercial fiber hardware. A few teams of researchers were the ones shoveling the bits, including the Sant'Anna School of Advanced Studies in Pisa, the National Inter-university Consortium for Telecommunications (CNIT), and good 'ol Ericsson. It's said to be the world's first transmission line operating at that speed, and what's most impressive is that it'll be tested on further network segments in the coming months ahead of becoming an actual product at some point in the not-too-distant future. Not soon enough.

    BDXL is the optical storage medium du jour, but the options for those wanting its capacious quad-layer burning capabilities in a tasty to-go form factor are fairly limited. Previous drives have lacked a certain... aesthetic appeal, but now Buffalo has unveiled its BRXL-PC6U2-BK, a slim and shiny external model that'll handle all of your BDXL disc-creation needs. The drive can run off a single USB 2.0 plug, though writing at 4x speeds requires a second USB connection to give it the juice required to do the deed. Slated for a release by the end of March, otherwise known as next week, this hot little onyx number will set you back ¥22,100 (about $275). Just don't go blowing all your cash on the drive -- BR-R XL discs ain't cheap, y'know.

    Big brains across the globe continue to unlock the secrets of the qubit and harness it for myriad uses -- quantum hard drives, quantum computers, and even quantum refrigerators. The internet may be next in line to get quantum-ized now that researchers from Northwestern University found a way to route a photon qubit through an optical cable without losing any of its physical characteristics. A newly developed optical switch does the deed, which allows fiber-optic cables to share multiple users' quantum info at once -- making superfast all-optical quantum communication networks possible -- and gets us closer to having our tweets and status updates whizzing to and fro at the speed of light.

    Okay, so maybe the whole brainpower thing is a distant second to the iPad itself, but still -- being a rocket scientist probably doesn't hurt when manipulating microscopic objects via a multitouch display. That's the kind of setup that students and boffins alike have going at England's University of Bristol, where iTweezers are being used to control a tiny rod about 300 nanometers wide, amongst other things. Essentially, the iPad is able to display what's under a microscope via a wireless display transfer, and then, touch points are converted into laser movements that are used to handle objects that are far smaller than those visible particles clogging up your left ear right now. All told, a user can select up to 11 different objects, and in theory, the iPad could enable scientists to do this remotely. Hey, we're all about new and improved ways to telework. Vid's below, kiddos.
