Concussions are becoming an increasingly large area of concern for professional athletes in a number of sporting disciplines. It's one of the reasons that Prevent Biometrics is putting its Head Impact Monitor System on sale. HIMS is a smart mouthguard that offers empirical evidence if a player has received a head injury. Rather than using a series of observational tests , which can prove ineffective, the system operates in real time. That way, as soon as a collision is detected, players can be hooked for medical treatment. The company has been testing its system for a while, and was previously available to selected teams across 2017.

Leave the watch in bright, direct sunlight for four hours, and you'll get an hour or so of GPS navigation. If you're at home, however, you can simply dump the G-Shock on its wireless charging plate and it'll be back to full strength in just five hours. The wireless charging is possible beca...
