iPhones bogging down Duke University's WiFi network?
While the Blue Devils may have their basketball program running like a well-oiled machine, apparently its wireless LAN structure is in dire need of an upgrade. Reportedly, so many Dukies have snatched up iPhones and began using the campus WiFi network to surf on the go that the hordes of requests have been "temporarily knocking out anywhere from a dozen to 30 wireless access points at a time." Cisco, the university's main WLAN provider, has been called in to find out exactly why the overload has brought the network to its proverbial knees, and we'd say they better resolve the problem pronto -- after all, this issue could be magnified immensely with the commencement of the fall semester.[Via Fox News]
The sights and sounds of RoboCup 2007
While you've already gotten a taste of the prep work involved at RoboCup 2007, we know a more multimedia-packed perspective of the gala is more likely to quench your appetite for roboto-a-roboto action. From mechanical canines bending it like Beckham to Wiimote-controlled AIBOs, Atlanta is the place to be if you're looking for all things robotic. Best of all, the gurus inside have translated their circuitry and programming skills over to the camera, and a well-stocked Flickr pool and YouTube library are already beginning to form. So go on, give the links below a gander, and be sure to check back as the week unfolds to catch even more of the madness at this year's RoboCup.Read - Northern Bites BlogRead - RoboCup 2007 Flickr poolRead - RoboCup 2007 YouTube library
RoboCup 2007: let the games begin
While we weren't able to get a first-hand glimpse of the mayhem that is RoboCup this time around, a camera-wielding Georgia Tech graduate student was able to do the honors for us all, and snagged quite a bit of impressive footage from the expo. Many of the shots were snapped during yesterday's practice rounds as competitors prepped their gear for battle (which began yesterday), and we must say that the oh-so-athletic Junior Soccer League robots are worth the price of admission alone. Still, even if witnessing robotic contention in person isn't enough to drag you to Atlanta, be sure to click through to get a glimpse of homegrown robotic innovation at its finest.
Virginia Tech football helmets monitor hits wirelessly
While the Virginia Tech Hokies tend to rely more on dazzling special teams teams play than sheer defensive prowess, the players take a lickin' regardless. In a presumed extension of Beamer Ball, the sparkly helmets donned by the football squad will sport internal accelerometers and wireless transmitters that beam (ahem) information about the seriousness of each blow to a Sybase database in order to tell if and when a certain player has had enough. The primary objective is to prevent any long-term injuries and detect concussions before individuals can even realize they're hurt, and an interesting byproduct of the system has shown what types of thwacks are typically sustained at different positions. The HITS (head impact telemetry system) technology could reportedly be used in places like the battlefield as well, or moreover, rigorous rounds of Wii Boxing -- but we're sure WVU's Punchstat system is already on top of that.[Photo courtesy of VT]
Georgia Tech researchers develop environmentally-powered nanogenerators
While the school of the Ramblin' Wreck may be best known for its barrage of engineering graduates, the university has been on quite the medical trip of late, as researchers have reportedly developed a nanometer-scale generator after already cranking out nanowires that monitor your blood pressure. The aptly-named nanogenerators can produce "continuous direct-current electricity by harvesting mechanical energy from such environmental sources as ultrasonic waves, mechanical vibration or blood flow," which translates into easy energy for implanted and worn medical gadgetry of the future. Interestingly, the project was funded by the likes of the National Science Foundation and our pals at DARPA, and while this invention may not quite match up with wireless charging (hey, we're scared of hospitals), the concept is novel nonetheless. So if you were hoping that dreams of implanted analysis of your vitals would suddenly cease, things aren't looking up for you.[Via MedGadget]
Survey sez LED lit parking garages seem safer
We had a sneaking suspicion that there was an ulterior motive behind Raleigh getting lit up as the "world's first LED city," and aside from savings tons of dough on energy bills over the next decade or so, it seems to make motorists feel a good bit safer, too. According to a before and after survey conducted by Mindwave Research, the number of respondents who "perceived the garage as very safe increased by 76-percent after the LED fixtures were installed." Admittedly, the newfangled lighting certainly added a new level of brightness to the situation, and the number of individuals who gave the garage an overall rating of "excellent" increased by 100-percent in response. The (unnecessarily lengthy) survey also added a few more minor figures to further prove that LED lighting is simply superior to the other stuff , but we're not yet sure if Cree will successfully use this ammunition to grab even more contracts to freshen up the city lights.
Microsoft developing virtual headphone algorithm
Considering that Vista isn't exactly getting perfectly positive praise, it looks like Microsoft is looking into other ways to bring cashflow to Redmond. While we already know the firm is diving head first into the VoIP handset market, it looks like it'll also be involved with a new virtual headphone. In an effort to allow VoIP / computer-based communications to be handled without tethering yourself to your PC and also allow you to hear ambient conversations around the office, researchers at Microsoft have "developed an algorithm that adjusts the timing of sound waves emitted from each speaker in an array, creating a focused beam of sound that acts as virtual headphones." Essentially, the speakers would create a "sweet spot" so that computer users could hear the audio perfectly, while individuals just inches away from the sound zone wouldn't hear much more than a peep. Furthermore, the focused wave technology could even bleed over into the tracking realm, which could actually allow the tones to follow one around as they move. Ideally, the creators want to conjure up a beamforming system that is easy to configure and relatively inexpensive, but we're hearing (ahem) that it'll be at least three years before these aural luxuries break into the corporate sphere.
Duke researchers envision mind-controlled weaponry
The Blue Devils certainly haven't fared well on the hardwood of late, but a group of engineering minds at Duke University are thinking up ways to get even. While we can't actually confirm the motives, a recent patent filing spells out details of a device that can "use the brain's thoughts to control an array of mechanical and electrical devices, up to and including weapons." Thought-controlled interfaces have long since been available, but these researchers are suggesting that everything from household items like televisions and ovens to "weapons systems" could be used to not only "improve one's quality of life," but could actually produce thoughts that litearlly kill. Interestingly, the verbiage even mentions that the recently-ratified UWB technology could be used to beam commands from your devious brain, and although it's not surprising to find that DARPA has a hand in funding department, we're still not any closer to finding out when our military will switch from triggers to impulses.

Mivx officially unveils MX-760HD HD WiFi media streamer
Mvix has certainly found its way to your living room before, and we've heard the rumblings of its latest HD streaming / storage device coming to fruition, but just before the holiday rush the firm is officially releasing the MX-760HD Wireless HD Media Center. This feature-laden box supports wireless media (HD thankfully included) streaming over 802.11g with full WEP support, and comes packed with an optional 200 to 750GB hard drive to store files remotely. Sporting a 7.4- x 7.6- x 2.3-inch enclosure, the Linux-based box plays nice with Windows systems and outputs in NTSC / PAL, and even includes an external LCD to give you quick updates on what's going where. Aside from WiFi, it also features Ethernet connectivity and USB ports, and Mvix even includes a remote to control the action from afar. On the rear, you'll find outputs for DVI, component, composite, stereo, and optical / coaxial digital audio to play back any of your DivX, MPEG 1/2/4, WMV, ASF, DAT, DVD, IFO, VOB, ISO, MP3, WMA, AAC, OGG, PCM, AC3, DTS, BMP, JPEG, and PNG files -- and that's just the tip of the iceberg. So if you're scouting a svelte HD streamer with internal storage to boot, the MX-760HD can be pre-ordered now (sans an internal HDD) for $329.[Thanks, Chris and Rich]
