Cobra iRadar detection system coming to Android next month
iPhone users have been able to avoid radar speed guns using Cobra's iRadar system since late last year, and it looks like Android users will soon finally be able to get in on the act as well. Cobra used the gdgt Live event at SXSW to announce that iRadar will be available for Android phones sometime in April. That consists of a standard dash-mounted radar detector and, of course, an app, which also takes advantage of your phone's built-in GPS capabilities to provide warnings of photo enforcement zones and other potential impediments to your inability to drive 55 -- you'll apparently soon even be able to share radar alerts with other iRadar users. Head on past the break for a video of the iPhone version.
Modified radar gun identifies suicide bombers up to ten meters away
William Fox of the Naval Postgraduate School in Monterey and John Vesecky, his colleague at UC Santa Cruz, are working on a modified radar gun that can identify suicide bombs worn under the clothing. To do this, they cataloged the most common arrangements of looped wires used to construct "suicide vests," and developed software that can identify the radar cross-section of each. So far, results have been pretty good: according to New Scientist, "telltale factors in the polarisation of the reflected signals" allowed them to correctly identify volunteers dressed as bombers up to ten meters away, roughly eighty-five percent of the time. Of course, even with a success rate this high, such a system would be prone to kicking up false positives. In order to minimize this, the devices would have to combined with other technologies, such as smart surveillance camera systems and infrared imaging.
RevFire system measures speed and spin, lets pitchers know when to throw in the glove
Pitching a baseball or softball isn't only about how fast you can get the damn thing across the plate, but how effectively you can spin the ball and control its position and timing as well. Well speed is easy to measure -- radar guns have been around for years -- but it's been more difficult for pitchers and coaches to determine how spin changes over time, with visual analysis generally being the best tool available. Well now thanks to a company called RevFire, teams can use a device of the same name to measure both speed and spin for multiple pitchers simultaneously as well as track individual performance through a number of practices and possibly even seasons. The one downside here is that the RevFire system uses proprietary balls to go along with the handheld monitor: two balls come in the package, so a few out of the park homers is all it takes to sideline the unit until replacements arrive. Unfortunately for would-be backyard flame throwers, RevFire seems targeted more towards organized teams than the lone gunmen trying to red shirt his or her local Little League team, a notion only furthered by the lack of pricing info on the product page. Sounds like a handy addition to the modern coach's tool chest, but maybe not so great for that washed up player who's been hanging on by good looks and a string for the last two seasons.
