Patent number: 7429247Abstract: A sleep state of a subject is estimated from respiration signals that are readily detected without restraining the subject. From a voltage waveform based on respiratory movement of a person, positive peak values and the (time) interval between adjacent peaks are calculated. Also obtained is the area of a region that is enclosed by the voltage waveform and a time axis between peaks, and the average value and dispersion value of the obtained inter-peak areas are calculated. The calculated values are used to set a preliminary sleep state value for a given period, and sleep state values over plural periods are factored in to estimate a sleep state at a given time point.Type: GrantFiled: July 1, 2005Date of Patent: September 30, 2008Assignee: Sanyo Electric Co.

Patent number: 7007327Abstract: To provide an adjustable bed that assists a user to turn comfortably in his or her sleep without mental stress. Once an automatic mode starts, measurement on the depth of sleep of the user lying on the bed is launched. The depth of sleep is measured by detecting biological information such as brain waves, heart rate, and respiratory rate of the user using electrode sensors or the like, and analyzing the biological information according to a polysomnography method or the like. If the depth of sleep is 0, i.e., the user is in REM sleep, and if one hour or more has passed since the measurement is launched or since an immediately preceding turn operation, a turn operation is performed to turn the user.Type: GrantFiled: September 10, 2003Date of Patent: March 7, 2006Assignee: Sanyo Electric Co., Ltd.Inventors: Atsushi Ogawa, Hideo Kawakami, Yoshihisa Fujiwara, Hidetaka Sakai
