Meanwhile, Cambridge-based MC10 is focusing on any number of other helmet-wearing athletes beyond cyclists. Rather than make a smart helmet, MC10, partnered with Reebok to create a mesh helmet insert called the CheckLight, which detects when an athlete suffers a blow to the head. An indicator light on the back of the neck shines yellow, red, or green depending on the severity of the impact. This will allow athletes to be checked on and treated right away for potential head injuries.
