As part of the main exhibit hall at Health 2.0, 6 sleep-related companies were demoing their devices and technologies, and Medgadget had a chance to hold short interviews with each one.

THIM is a sleep tracking ring that helps you fall asleep by waking you up. The way it works is that you put the THIM ring on any finger when you go to bed. Based on your movement, an accelerometer in the device detects when you have fallen asleep and then, three minutes later, it wakes you up!
