    Molasses, snails and glaciers: none are slower than an organization developing a new wireless standard. The Bluetooth Special Interest Group (SIG) is no exception -- it's been nearly three years since it announced it would roll Wibree into Bluetooth and four months since it made Bluetooth 4.0 official, but still no dice. This week, the SIG says the low-power specification is ready for action, its minutiae finalized. However, fine print in the org's press release disagrees. The main reason for Bluetooth 4.0 was to include lower power devices, but that all-important integration is still pending a "before June 2010" completion date. That means we still won't see Bluetooth-toting cats till the end of the year, and we have no idea what SIG has accomplished in the meanwhile. Press release after the break.

    Even though this morning's presentation had Apple calling themselves the "largest mobile device company" in the world, apparently they're in the processor business now, too. The just-announced iPad doesn't carry any special Intel or Nvidia CPU -- it's a homecooked 1GHz chip called the Apple A4. Apple says it's designed for high performance and low power, which is probably how they got that crazy 10 hour battery life and one month (!) standby life. We guess that PA Semi acquisition was a good idea. We've been hearing for a while that Apple was picking up chip designers and hiring specialists for chipmaking, and it looks like the A4 is the first release (fourth produced?) product of all of that. It'll be interesting to see how their first major foray into silicon works out.

  • LED traffic lights don't melt snow, do cause accidents

    A number of cold weather American states are reporting their dismay at finding out that LED traffic lights are so energy efficient that they do not produce enough excess heat to dissipate any snow that covers them. It turns out, perhaps in an homage to bad engineering everywhere, that the inefficiency of incandescent light bulbs was previously relied upon to keep traffic signals unimpeded. The new LEDs do not achieve the same effect, which has resulted in a few accidents and even a death being blamed on obstructed traffic lights. Feel free to apply palm to face now. It's not all gloomy, though, as the majority of people are said to treat a dysfunctional traffic light as a stop sign (how clever of them), and a tech fix is being worked on as we speak.

  • AMD 's new Athlon II processors aim to go easy on the power, your wallet

    AMD has just outed a selection of new Athlon II procs, which do little to help it reclaim the performance crown, but will be of interest to anyone who likes to keep things minimal -- whether we're talking about prices or temperatures. Starting at $69 per chip (when bought in bulk) with the 2.7GHz dual-core X2 235e and topping out at $143 for the 2.3GHz quad-core X4 605e, AMD's new e-tagged processors operate within a 45W thermal envelope, as opposed to the relatively standard 65W TDP. The Sunnyvale outfit makes some ill-advised claims of "up to 75 percent" better performance versus comparable Intel CPUs -- the small print tells us that number is derived from 3DMark Vantage while testing with different GPUs -- but we suppose until the Thuban six-core shows up, AMD will have to take performance gains from wherever it can get 'em, including its own imagination.

    Texas Instruments is pretty chuffed with itself right about now, as it's prepping to demonstrate a swell-sounding new system-on-chip that takes Bluetooth connectivity to the extreme reaches of low energy consumption. About to be shown off in Munich tomorrow, the new CC2540 takes up a measly 6mm-squared of real estate, and is said to be able to operate for more than a year on a single button cell battery. With the reduced physical size and embedded Flash memory, this should be easier to install and update as necessary too. Considering the battery-draining ways of current Bluetooth tech, such claims sound preposterously awesome, but we'll keep our giddy enthusiasm in check until early next year when samples will begin rolling out. For now, you can check out the older video below 'splaining the prospective benefits in more detail.

  • AMD's Neo to hit nettops, all-in-one PCs soon

    AMD's Neo ultra-portable platform was seen as something that just might rival Intel's mighty Atom in the oversaturated netbook space when it debuted back in January, but up until now, the system has remained largely in the background. Indeed, it has only found its way into a select few machines, none of which have managed to gain any sort of traction beside the sea of Atom-based alternatives. Now, however, it seems as if the chips -- which were originally engineered for ultraslim, thin-and-light laptops -- may find themselves shoved into an array of nettops and all-in-one PCs. Here lately, a slew of underpowered SFF-type desktops and PC-in-a-monitor type units have found favor with bargain hunters, and Bob Grim, the outfit's director of client marketing, isn't looking to miss a golden opportunity. To quote: "We've known all along that this type of technology would really work well in multiple platforms and multiple types of form factors. These CPUs perform better than the Atom processor, and the graphics are superior. These things... can play Blu-rays, they can play games."There's still no word on who exactly plans on equipping their future machines with this here platform, but considering just how tired we are of Intel's sluggish N270 and N280, we'll take all the competition we can get.

    Electrical engineering researchers at the University of Tokyo have developed a flexible, stretchable OLED that acts something like rubber, and does not tear or break when stretched. The material is produced by spraying a layer of carbon nanotubes with a fluoro-rubber compound, creating a rubbery, conducive material. The current, monochrome display prototype has a resolution of just 256 pixels, is 10-centimeters square, and can apparently be folded about 1,000 times with out falling apart, tearing, or imploding. The team is presenting its findings in the British science journal Nature Materials this month.[Via Slashgear]

    Seagate's Barracuda drives have been plagued with a few problems as of late, but it looks like the company is doing its best to push the line in a fresh new direction with its just-announced Barracuda LP series, which promise to cut down on power consumption without making too many compromises in performance. Specifically, Seagate says that the drives will use up to 50% less electricity than standard hard drives, while also cranking out 5,900 RPM, along with an average latency of 5.5ms, and a 32MB cache. No word on what so of premium, if any, they'll demand, but you'll apparently be able to get 'em in 1TB, 1.5TB, and 2TB varieties (all 3.5-inch) right out of the gate.

    fit-PC Slim is billed as the "smallest, most energy efficient PC available," and at 13 ounces it just might be. Slim is housed in a 330cc enclosure (4.3 x 3.9 x 1.2 inches), draws a mere 6 watts of power, and like the Linutop 2, runs on a 500MHz AMD Geode. This machine is available in a pared-down 256MB configuration (sans WiFi, hard drive) for $220; a 512MB WiFi version (with no hard drive) for $245; or go all out with the 512MB / WiFi / 60GB hard disk version pre-installed with either Ubuntu or Windows XP Home SP3, for $295 or $335, respectively.[Via LinuxDevices]

  • Texas Instruments gets excited about energy scavenging

    Texas Instruments has a lot to do with the original microchip, if for no other reason than being the employer of inventor Jack Kilby. Now, however, TI is looking to produce chips and other related gizmos that require an infinitesimally small amount of energy to operate. The overriding theme guiding the engineers is "energy scavenging," which alludes to grasping power from even the most unlikely of places -- vibrations from a bridge as cars pass over, capturing wasted exhaust from a car or bottling up all that frustration your sibling shows when you own him / her again in Super Smash Bros. Brawl. The possibilities are just about endless, with networked battery-free smoke alarms, solar-powered mobiles and gaming laptops that feed off of extraordinarily focused brain waves in the mix. Okay, so that last one is still eons from reality, but at least we're headed in that direction.

    If you're after a really, really low power, small footprint, generally inoffensive desktop solution, you probably can't do better than the new Linutop 2. This miniscule, Xubuntu-based system runs on top of a 500MHz AMD Geode CPU, packs in 512MB of RAM, and 1GB of flash memory, you know, for applications and stuff. Of course, the draw here isn't massive specs, but rather a tiny drain on energy, and a simple, cheap solution for people with basic computing needs. Amazingly, the Linutop 2 uses only 8 watts of power, and weighs a feather-light 20 ounces. The miniature box also has four USB ports, an ethernet jack, audio outs, and comes bundled with open source gems like AbiWord, Open Office, and your good buddy, Firefox. The little guy starts shipping on February 26th for €280, or about $412.[Via LinuxDevices]

  • AMD's low-power Phenom X2 GE-series CPUs seen in latest roadmap

    AMD's high-powered Phenom lineup should still be residing in the forefront of your memory, but the company has now loosed details on a series of processors that cater to the more energy-conscience crowd. The Phenom X2 GE-series CPUs currently consist of a trio of units, each reportedly scheduled to land sometime in the first quarter of 2008. The chips all sport thermal design power (TDP) ratings of 45-watts, and while the GE-6400 will clock in at 1.9GHz, the GE-6500 adds 200MHz but lags behind the flagship 2.3GHz GE-6600. The whole lot touts 2 x 512KB of L2 cache, 2MB of L3 cache, and an (estimated) 3,200MHz HT3 bus, so go on and start pinching those pennies for the moment these land in a Socket AM2+ motherboard near you.

    Joining the fairly saturated Bluetooth GPS market -- but not exactly competing for that "world's smallest" crown -- is Amaryllo's Purity. Sporting a 3.39- x 1.73- x 0.52-inch enclosure and weighing 2.08 ounces, the sleek, matte-finished device sports internal Bluetooth for connecting with PDAs, smartphones, and other GPS-lovin' gizmos, and receives its intel via the SiRF Star III LP (low-power) chipset. Reportedly, the unit can muster 15 hours on a single charge, and should also ship with a car charger, AC adapter, rubber anti-slip stickers, and a silicon protections sleeve. While we doubt this €90 ($118) receiver will see US shores anytime soon, it's slated to land in Europe next month, but we American (and Taiwanese) lads have plenty of alternatives to choose from, anyway.[Via NaviGadget]

  • Apple receives patent for hybrid low-power Bluetooth mouse

    Although it took Apple quite awhile before taking its Mighty Mouse to the Bluetooth realm, it looks like Cupertino could have yet another mousing device up its sleeve, this time requiring a few less AA cells to keep that cursor moving about. In a recent patent granted to the company, plans for a "hybrid low-power computer mouse" were laid out, including mention of the Bluetooth protocol. In a presumed attempt to please environmentalists and cut down on battery requirements, the new device would sport both an accelerometer and an optical tracking engine (hence the "hybrid" moniker), and wouldn't activate the latter until the accelerometer's "tracking information is deemed inadequate," hopefully reducing the power usage in its optical mouse. Of course, we've no idea if (or when) Apple plans on implementing this snazzy new design into their current mice, or if it plans to kick out a different animal altogether, but Mr. Jobs would probably love nothing more than for regulators to grab hold of this and force other mice breeders to lay down royalties for the sake of Mother Earth.[Via SlashGear]

  • Apple considered small chip startup over Intel?

    Steve Jobs' announcement -- almost a year ago, now -- that Apple was transitioning to x86 processors was one of the most shocking bits of news that the industry had ever heard, and yet there were a group of employees at a startup chip manufacturer called PA Semi who were even more shocked than most, according to reports, because right up until that keynote, they were sure that their company, and not Intel, would be chosen to supply the brains for what's now known as the MacBook family of laptops. The Register is reporting that PA Semi had a close relationship with Apple in the months prior to the switch, and that the two companies were working together to gauge the feasibility of running native PowerPC-coded software on 2GHz dual-core chips that PA Semi claims run at only a third of the 21 to 25 watts consumed by Intel's Core Duo models. Sources who spoke to El Reg say that executives were virtually positive that they'd win the contract, and that CEO Dan Dobberpuhl was understandably "furious" when he found out PA Semi had been passed over. The company still has a bright future developing chips for the embedded market and storage devices, but they'll probably never again have the opportunity to become an instantly-recognized name like Intel, AMD, or IBM.

    Citizen has developed something it's calling the "memory liquid crystal," a new passive matrix LCD that can retain an image even when powered off. According to Citizen, the display's inorganic membrane, combined with an angled orientation, keeps the crystals frozen in position without power having to be maintained. The five-volt, non-backlit display isn't going to take the place of your LCD TV anytime soon, but is planned for use in point-of-sale applications, watches and cellphone auxiliary displays.
