ABSTRACT:
A method and an apparatus are disclosed for scoring the quality of sleep experienced by a subject wearing the apparatus for a specified period. This sleep monitoring apparatus includes a motion sensor that quantifies the temporal variation in the subject's motion, an analog to digital converter to sample the sensor data, a microprocessor with embedded programmable memory to store control and processing firmware, a memory device for data storage, a display means, and a switch for staring and resetting the device. The firmware for this apparatus: (i) directs the microprocessor to sample sensor output at a prescribed time interval and to temporarily store this data in the memory device, (ii) directs the microprocessor to analyze the temporarily stored data to compute a sleep score based on the magnitude of movements recorded during the monitoring period, and (iii) controls the operation of the display means. Upon termination of the sleep period, the apparatus' display means will display a sleep score based on a scale of 0 to 100. A high score indicates restful sleep (very low movements), while a low score indicates excessive restlessness during the monitored sleep period.
