[His concoction, dubbed the Wireless Impact Guardian (WIG), looks like your average helmet at first glance, but a quick look inside reveals electronics designed to sense an impact, judge if you're conscious and dial for help if necessary. Essentially, an alarm is triggered upon impact, and if you're not cohesive enough to disable it after 60 seconds, it automatically rings up 911 and beams out your location via GPS so that medical personnel can get moving
