SLEEP CYCLE MEASURING APPARATUS

摘要

PROBLEM TO BE SOLVED: To provide a sleep cycle measuring apparatus for infants, capable of measuring the sleep cycle without applying physical or mental burdens to an infant subject.

SOLUTION: The sleep cycle measuring apparatus is composed of: a biological vibration detecting means for detecting biological vibration of the infant; a biological signal detecting means for detecting a biological signal from an output signal of the biological vibration detecting means; a biological signal intensity dispersion value computing means for computing the dispersion value for a prescribed time of the intensity of the biological signal acquired by the biological signal detecting means; and a sleep cycle detecting means for detecting the sleep cycle from the dispersion value of the intensity of the biological signal acquired by the biological signal intensity dispersion value computing means.
