Panasonic details radar-based technology that can detect collisions in low light
Collision detection for cars? Yeah, scientists are on that. But whenever we read about concepts like this, the accompanying literature is often curiously light on details pertaining to real-life driving conditions; it's often unclear how well the tech will fare if you dredge it up on a foggy day, or in the middle of torrential storm. But in that press release you see down there, low visibility and poorly lit roads are all Panasonic wants to talk about. The company just unveiled its new crash-avoidance system, which, like other concepts we've seen, uses millimeter-wave radar technology to detect pedestrians and bicyclists. Since humans tend to reflect weaker radar signals than cars, Panasonic has designed a new pulse radar code sequence that allows pedestrians to leave a bigger footprint. It's so effective, the company claims, that it can detect bystanders up to 40 meters (131 feet) away, and will work at night and through rain, fog, snow and blinding sunlight. That all sounds promising, of course, but as with other concepts, it's not clear, when, exactly we'll see this system put to good use in the real world.
DARPA planning high-speed wireless for soldiers in the field
DARPA has its hands and, more importantly, its money in just about everything. Weapons, robots, thermal sensors -- it's a staple of the scientific community. But, it's also a military agency with basic needs, like internet access. The research group's newest project doesn't carry heavy loads (unless you're weighing your cargo in kilobytes) and can't break the sound barrier, but it should be able to deliver 4G speeds to even the most remote of battlefields. DARPA has $11.8 million set aside for its Mobile Hotspots program which will use millimeter-wave signals to deliver high-speed data connections to dismounted soldiers, forward-operating bases and tactical centers. Most importantly, each node in the network extends its range building out a mesh that isn't reliant on existing infrastructure. For more details hit up the PR after the break.
Multi-gigabit wireless broadband within our grasp, capped data plans laugh in our face
Bring it on, LTE-Advanced. In case you've been looking for ways to eat up your capped data plan any faster, a researcher from Samsung proclaims that speeds up to 5.5gbps (yes, with a g) might be reachable within the next five years -- as long as all the stars align, that is. Jerry Pi demonstrated the idea, which involves the use of millimeter wave spectrum that lies between 3GHz and 300GHz. If -- and that's a big if -- the spectrum can be secured, the next hurdle will be the engineering challenge of deploying a wireless broadband network at such high frequencies; even tiny oxygen molecules, let alone walls and trees, would easily break up a signal at that range. Pi mentions that he and his fellow researchers are working on a few ideas to get around these obstacles, and outlines everything in significant detail in his 100+ slide presentation, which can be accessed below. Don't get us wrong: the idea of broadband data speeds hitting 5.5gbps makes us salivate, but it would definitely need to come with an unlimited plan. Just sayin'.
Toyota's new crash-avoidance technology takes control of the wheel
Crash-avoidance technology in cars is hardly anything new, of course, but Toyota's gone a bit further than most with its latest effort. While complete details are still a bit light (including any word of an actual rollout to vehicles), the new system is said to use a combination of both front and rear cameras, and millimeter wave radar technology to detect pedestrians or obstacles that could lead to a crash. The real kicker, however, is that when the car does detect a possible collision, it actually takes control of the wheel to avoid it instead of just stopping the vehicle. What's more, that's just one new safety measure that Toyota recently showed off to reporters in Tokyo -- it's also working on things like a pop-up hood that could provide some additional protection in the event of a crash, and a steering wheel that can measure the driver's heartbeat and avoid a crash if they suffer a heart attack.
Handheld millimeter / microwave camera to see through walls, your underpants (video)
You know those scanners that peep your naughty bits at the airport? Well, a team of researchers have been working on a handheld camera that sports the same technology, and while they're touting its future impact on stuff like cancer detection and aerospace engineering, we can't help but squirm thinking about its Peeping-Tom potential. The camera currently takes 30 images per second by transmitting millimeter and microwaves to a "collector" on the other side of a subject, and then sends them to a laptop for real-time inspection. Aside from being able to see straight through your BVDs, it can also be used to detect defects in spacecraft insulation, find termites lurking in the walls of your apartment, and help in the diagnosis of skin disease. The camera's creators are working on a smaller, one-sided version of the device that could have mass-market appeal -- we just hope this thing stays in R&D long enough for us to get our bikini bodies back. Check out a video of its G-rated abilities after the break.
Hitachi, Panasonic and Toshiba to deliver 60GHz wireless products in 2H 2010
The year's 2010, yet we're still leering at the dusty pile of cables behind our AV equipment and wondering, "O UWB, where art thou?" Well, the folks at Tech-On have got a little update for us: Hitachi, Panasonic and Toshiba are reported to be delivering products donning 60GHz wireless chips -- which sip little juice but churn out 7GHz of colossal bandwidth and 1.5Gbps of data rate -- in the second half of this year. While none of the manufacturers are directly pimping either WirelessHD or WiGig, it appears that Hitachi and Panasonic are siding with WiGig's extra functionalities like media access control (MAC), and the latter even envisions "embedding the functionality into portable gear" for downloading digital content from kiosks. Either way, it's nice to see some progress here -- we don't want things to drag on any longer, do we?
TSA's Millimeter scanners see through clothes, installed at 10 airports
Leave it to the TSA to come up with new ways to check out what you're packing. In this case, those body-scanning machines we've known about for some time are being installed in 10 airports. They are already being used in Los Angeles, Baltimore, Denver, Albuquerque, and New York's JFK. Later this month, the TSA will add the bum-looking devices to major airports in Dallas, Detroit, Las Vegas, and Miami. By bouncing millimeter waves off passengers, the scanners produce a black-and-white image that's detailed enough to see the sweat on someone's back (among other things). The program is aimed at detecting objects such as plastic and ceramic weapons that aren't normally picked up by traditional methods. The technology does have a couple drawbacks, however: it can't see through plastic or rubber materials that resemble skin. Keep that in mind the next time you wear vinyl pants on your next trip to Mars, kids.[Via Crunchgear]
60GHz wireless chip promises 5Gbps of throughput, instant tumors
So this team of über-nerds -- NICTA -- out of Australia's Information and Communications Technology Research Centre of Excellence (or ICTRCoE for "short") announced the preliminary results of their Gigabit Wireless Project. Here's a hint: they were able to transmit gigabits of data -- five of 'em -- per second wirelessly over 60GHz / millimeter-wave CMOS-based transceivers. Of course, range on a system with that high a frequency isn't very far, but feel free to enjoy this moment of fantasy-future news for what it is. Oh, and NICTA crew -- hate to break it to ya, but your countrymen at CSIRO broke the 10Gbps wireless barrier a couple years ago (as did the U of Essex), might be time to up the ante.Update: Bonus! Apparently these will be ready to ship in a year, and would cost $10 per component, which is still a little expensive for a single wireless chip but not bad at all.
IBM and MediaTek team up on uber-fast chipsets for HD streaming
IBM ain't the first big fish to dabble in the wireless HD chipset realm, and while we'd heard that the outfit was looking into the matter a year ago, things are seemingly now moving forward. Big Blue has joined hands with MediaTek in a "joint initiative to develop ultra fast chipsets that can wirelessly transmit a full-length high definition movie to and from a home PC, handheld device, retail kiosk or television set nearly as fast as a viewer can push their remote control." Apparently, the happy couple will both utilize their knowledge of millimeter wave (mmWave) radio technology in order to construct chipsets that allow end users to fling a 10GB file to its destination in just "five seconds" -- all without wires, of course. Visions of uncompressed HD streaming, syncing entire music libraries in seconds and giant bonfires fueled entirely by cabling (we kid, we kid) immediately come to mind.[Via Slashdot]
