Title: Kazuhide Shigeto: Innovator in Sleep Quality Estimation
Introduction
Kazuhide Shigeto is a notable inventor based in Susono, Japan. He has made significant contributions to the field of sleep quality estimation, holding 2 patents that focus on innovative devices and methods for assessing sleep quality.
Latest Patents
Shigeto's latest patents include a sleep quality estimation device and a sleep quality estimation method and program. The sleep quality estimation device utilizes a respiration sensor to detect the respiratory waveform of a subject. A sleep stage estimation unit then estimates the subject's sleep stage based on this waveform. Additionally, a sleep rhythm model database records models associated with the appearance probability of δ-wave during sleep stages. The sleep quality estimation unit estimates the appearance time of δ-wave during sleep and evaluates the subject's sleep quality based on this data.
Another patent involves a stimulatory effect estimation device and a sleep depth estimation device. This device includes a stimulus generator that applies stimuli to a back seat passenger and an electroencephalogram that measures the passenger's brain waves. The system estimates the stimulatory effects experienced by the passenger while awake and asleep, allowing for a tailored stimulus application based on the relationship between these effects and changes in sleep depth.
