Playing contact sports is all fun and games (literally) until someone gets a concussion, or worse. It’s not always easy to tell between the player that’s laying on the ground because he got the wind knocked out of him, or the one that needs medical attention because his brain got a shakeup. The ShockBox is a special sensor that is meant to be placed either on or inside a helmet, and it contains two things: an accelerometer and a Bluetooth radio. Should any one player experience a severe hit, a signal is immediately sent to a paired smartphone (say, the coach’s) with impact data and analysis. It uses long range Bluetooth, so the device has a range of up to 100m, and one smartphone can pair with up to 128 sensors at once. This means you could conceivably monitor an entire team, and provide medical assistance when needed. ShockBox installs with 3M double sided tape, which is provided with your $149 unit. Yeah, that’s a lot of money to fork over when you’re decking out an entire high school football team, but if you’ve got the budget, you don’t want to be skimping on safety.
