Patent ID: 6878121

Claim:
A sleep monitoring apparatus for scoring the quality of sleep experienced by a subject wearing said apparatus for a specified period, said sleep monitoring apparatus comprising: a means for sensing the temporal variation in the motion at the location where said apparatus is being worn, an analog to digital converter connected to said sensing means for sampling the data sensed by said motion sensing means, a microprocessor connected to said converter, said microprocessor having embedded programmable memory, a means connected to said microprocessor for storing data, a display means connected to said microprocessor, and firmware that controls the operation of said apparatus by directing the microprocessor to sample the output of said sensing means at a prescribed time interval and to temporarily store said sampled data in said data storage means, by directing the microprocessor to analyze the temporarily stored data to compute a sleep score based on the magnitude of movements recorded during said monitoring period, and by controlling the operation of said display means to display said sleep score.
