From Reebok, it's called the Checklight.
quote:
There are two key features that separate CheckLight apart from previous athletic impact sensors. First, its flexible design measures the impact on a wearer's head, as opposed to the impact on a helmet, which -- according to Kacyvenski -- means that the data it provides is more relevant and accurate than competing systems. And, it means that the CheckLight can be used with multiple helmets.
CheckLight's second value proposition lies is its ability to provide simple, actionable information to both athletes and medical personnel. The simplicity of its yellow light/red light warning cues makes it easy to understand by the players themselves which removes the pride and shame factor that prevents many players from reporting concussion symptoms. That may be where the real genius of the CheckLight lies -- by giving players a means to easily see when a teammate may have a concussion, they police each other. This addresses the biggest difficulty in diagnosing concussions: the failure to report symptoms. CheckLight does the reporting for you, thereby removing the human element from the equation.
