You're biking along, minding your own business. You reach an amazing downhill stretch. You pick up speed. You're really cranking along. Oh no! A hippopotamus wanders onto the trail! You swerve and end up faceplanting in the bushes.
Don't fear, your helmet will dial your emergency contacts and give your location. The ICEdot Crash Sensor is a stick-on sensor that mounts onto your helmet. It connects to your smartphone via Bluetooth. When it senses an impact, it sounds an alarm and starts a countdown clock on the crash sensor app. You have a set amount of time to turn it off.
If you're incapacitated and don't turn it off, the app will notify your emergency contacts with a text message and share your GPS coordinates so they can send an ambulance, come check on you, or dispatch a Saint Bernard with a barrel of brandy.
The ICEdot makes sense for adventuresome action-sports types who travel alone or play in isolated areas. Of course, the wild card in all of this is whether or not your phone survives the impact. If you're doing extreme sports, then you probably already have a tough case for your phone and store it someplace fairly safe.
The crash sensor is currently raising funds on Indiegogo. A $150 pledge will get you a sensor of your own should the project net enough funding. For $1,000, you can get in on the beta field test of the device.
