A Gentler Reveille

This armband measures the wrist motion of a sleeping user and transmits the data to a smart phone over a Bluetooth connection. An application on the phone analyzes the motion and determines when sleep is shallowest. An alarm can then wake up the sleeper at the optimal moment within a preset window of time, such as between 7:30 and 8:00 a.m.
