Georgia Tech researchers developing tricorder-like medical scanner
We've already seen some attempts to create a tricorder-like device, but this latest crack it at by some researchers at Georgia Tech looks like it could well be the closest to the real thing to date -- if it ever turns into an actual device, that is. The big advance with this one, it seems, is the use of a new mosaic narrowband filter, which includes photosensitive pixel sensors that can observe different wavelengths and allow for multispectral imaging. According to the researchers, the filter could also be laminated with standard imaging sensors used in digital cameras, making an all-in-one handheld device possible. That would apparently let individuals use the device to detect everything from the severity of bruises to contamination in food, or even perform remote sensing in mining, to name but a few applications. The researchers still have quite a bit more work to do on it before any of that's possible, however, and they're now seeking collaborative or financial support to further develop the device.[Via Daily Tech]
Portable medical scanners built to interface with cellphones
You know those elephant-sized medical scanners? Totally amazing machines, sure, but things like that aren't apt to be shipped into obscure jungles throughout Africa. Thankfully, a team of researchers have developed something that could bring medical scanning to an even larger chunk of the world: a real live Tricorder. Of course, it's not really going by that moniker, but the diminutive scanner is able to interface with a cellphone via USB and utilize its 3G / WiFi access to send raw scan data to servers and receive images back. Granted, you won't get any high-resolution viewing from your average mobile, but it's certainly a step in the right direction.
Purdue researchers craft handheld chemical analyzer, likens Tricorder
Hot on the heels of being crowned the most prolific pirating university in the land, Purdue is donning its halo once again by kicking out yet another invention that will surely make the world a better place to reside. The Mini 10 prototype is a handheld chemical analyzer that its creators have likened to Star Trek's "Tricorder," and while the internal abilities should genuinely impress, we're handing out a round of golf claps for the uber-glitzy motif it's got going on. The sophisticated sensing system measures just 13.5- x 8.5- x 7.5-inches and weighs in at 22-pounds, which is around 30 times less than conventional mass spectrometers, and aside from its ability to be completely portable via battery power, it still sports the same sniffing capabilities as its mammoth-sized siblings. In order to cram such potent chemical sensing abilities into such a small package, a miniature mass spectrometer is "combined with a technique called desorption electrospray ionization (DESI)," and can display the chemical composition of materials in a "matter of minutes without harming the samples." Interestingly enough, the prototype has already analyzed garb, food, and actual cocaine, and while we're not quite sure when you'll be able to snatch one of these up to "check in" on your mischievous teen, a couple of Indiana-based firms are apparently already looking into commercialization options.Slashdot]
