Microdrones' flying robot films African wildlife, finds peace with nature

Sit back, relax and grab a cold one, because you're about to take an aerial tour of the Serengeti, courtesy of that flying drone you're staring at. Developed by Microdrones, this MD4-100 quadrotor was recently sent off to Kenya, where it gathered footage for a TV nature documentary produced by TBS Japan. By hovering over the terrain, the craft was able to get relatively up close and personal with zebras, elephants and other wildlife, without creating the same kind of disturbance that heavy duty, camera-laden trucks can wreak. Presumably, that's because the animals have no idea what to make of a flying robot, though part of us wants to believe there's some sort of full-circle, techno-evolutionary dynamic at work here, momentously bringing bot and beast together in some sort of pre-apocalyptic symbiosis. But that's just us. Hover past the break to see the video for yourself.

EnerJ power-saving system prioritizes CPU voltage, may reduce energy consumption by 90 percent

It takes a lot of energy for computing systems or data centers to patch up critical errors, but what if we devoted less power to fixing less urgent issues? That's the basic idea behind EnerJ -- a new power-saving system that could cut a chip's energy consumption by 90 percent, simply by prioritizing critical problems over those that are less threatening. Unlike, say, liquid cooling techniques, the University of Washington's framework focuses exclusively on the programming side of the equation and revolves around two interlocking pieces of code: one that handles crucial, precision-based tasks (e.g., password encryption), and another designed to deal with processes that can continue to function, even when facing small errors. The system's software would separate the two codes, meaning that energy from one section of the chip would never be used to fix a major problem that the other should address, while allowing engineers to more efficiently allocate voltage to each region. The system has already cut energy usage by up to 50 percent in lab simulations, but researchers think the 90 percent threshold is well within their reach, with computer engineering professor Luis Ceze (pictured above) predicting that the system may even be able to increase battery life by a factor of ten. The team is hoping to release EnerJ as an open-source tool this summer, but for now, you can find more information in the PR after the break.

Researchers hack Kinect for glasses-free 3D teleconferencing (video)

Source: http://www.engadget.com/2011/06/02/researchers-hack-kinect-for-glasses-free-3d-teleconferencing-vi/

Since the dawn of Kinect hacking, we've seen cameras strung together (or rotated) to create 3D, video game-like environments, while others have tweaked it for headtracking. Others, still, have used it for teleconferencing (albeit, the flat, two-dimensional variety). Now, a team of researchers have gone and thrown it all together to achieve 3D video chats, and if we do say so, the result is greater than a sum of its parts. The group, based out of UNC-Chapel Hill, uses 3D mapping (and at least four Kinects) to render the video, and then employs headtracking on the receiving end so that people tuning in will actually see the live video in 3D, even without wearing 3D glasses. The result: a tableau that follows you as you move your head and spin around restlessly in your desk chair waiting for the meeting to end. That's mighty impressive, but we can't help but wonder: do you really want to see your colleagues in such lifelike detail? Have a gander at the video and decide for yourself.

Micron RealSSD P320h can read 3GBps, write 2GBps, impress millions of geeks per second

Source: http://www.engadget.com/2011/06/03/micron-realssd-p320h-can-read-3gbps-write-2gbps-impress-millio/

Speed may be a relative thing, but whatever you choose to compare Micron's new RealSSD P320h series to, you'll probably find them pretty competitive. Coming in 350GB and 700GB capacities, these PCI Express solid state drives can process data at a rate of 3GB per second and write it at a no less impressive 2GBps. If you're more interested in input / output operations per second, the P320h clocks in at 750,000 IOPS when running Linux or 650,000 with Windows Server as the OS. You don't need us to tell you that both numbers represent screaming-fast performance. Such mighty feats are achieved with the use of 34nm SLC NAND flash memory and Micron's own controller chip. Samples of the P320h are trickling out now and mass production is coming in the third quarter of 2011, and while no pricing info has been offered yet, it's safe to say you'll be needing your company CFO's blessing before making any P320h purchases. Video and full PR after the break.

OCZ RevoDrive 3 X2 and RevoDrive Hybrid hands-on (video)

Source: http://www.engadget.com/2011/06/03/ocz-revodrive-3-x2-and-revodrive-hybrid-hands-on-video/

We got a chance to spend some time with the lovely folks from OCZ here at Computex for a tour of their latest and greatest SSD products, the RevoDrive 3 X2 and RevoDrive Hybrid. Both are PCIe x4 cards featuring up to 4 SandForce SF-2200 controllers and RAID 0 (striping) for blazing performance. The RevoDrive 3 X2 is available in capacities from 240GB ($699) to 960GB and improves upon the RevoDrive X2 with TRIM support and double the performance. We were treated to a demo that achieved truly ludicrous speeds -- 1.5GBps reads and 1.2GBps writes -- the kind of numbers that'll perk up even the most jaded PC enthusiast. The RevoDrive Hybrid builds upon the same SSD technology as the RevoDrive 3 X2 to cache the contents of a 2.5-inch hard drive, with capacities starting at 500GB with a 60GB cache ($350). OCZ's demo showed a 20 times performance improvement going from a regular hard drive to the RevoDrive Hybrid. Both products are expected to ship in July, but we suggest you ogle them right now in the gallery below and in our hands-on video after the break.
