We've seen a couple helmet systems that monitor impacts -- including prototype football helmets -- but Riddell is bringing the tech to market with the Revolution IQ HITS (Head Impact Telemetry System) helmet, which contains a system of sensors that stores data about the last 100 impacts, which can later be wirelessly transmitted to a laptop for analysis. Up to six $999 helmets can be linked to each $299 HITS receiver, and players and trainers can access data via a web app for later evaluation. The helmet is shipping now, and apparently the University of Missouri and several other NCAA schools have already placed orders.[Via Technology Review
