#2How can it "measure the movement of individual air particles"?
I'm guessing that it measures the phase shift of received signals between measurements across the device and uses this to triangulate the origin of the sound. Their website doesn't give much insight.

> At its heart are two platinum strips, each 200-nanometers thick (about 600 atoms across) by 10 micrometers wide. They're stretched parallel across a gap and heated to 200 degrees Celsius when operating.
> Air particles flowing past the strips cool them unevenly. The pattern of cooling and heating is analyzed by signal-processing software, created by Microflown, in a compact PC, such as the CompuLab fit-PC2.
They've got a couple cool images of the device on that page, too.

#5A "battlefield" is an extremely noisy environment. I've worked on bots of such nature for a living and while the concept they describe makes sense at a modelling level, their process has very little field application (Dedicated IIR-ESP when you're getting shot at?). As far as pinpointing the location of gunfire goes, you are trained in Target Detection (TD) and have mounted systems like Boomerang on HMMVs. Trust me, when you've been out there long enough, you don't need a gadget to tell you what kind of gun the shot was fired from or the sort of aircraft approaching.
Cool concept nonetheless, I hope they publish more details.

According to the press release, it can pick out & identify sounds from inside cars at a crowded checkpoint, or allow a soldier to act as an air traffic controller in zero visibility. I'm not sure if it'll live up to the hype, but it seems useful.

thanks, those pictures were pretty cool.
