摘要： A pulse wave sensor main unit is provided with a pair of band anchoring portions that are positioned in the direction of the circumference of the wrist and through which the band is passed. Strip-shaped band insertion holes are formed in the band anchoring portions. The band is an elastic long strip-shaped body. The band is formed of material such as rubber that is flexibly deformed when external force is applied and is restored to its original shape by its own elasticity when external force is removed. The band is so set that its thickness is larger than the dimension of the shorter sides of the band insertion holes and its width is larger than the dimension of the longer sides of the band insertion holes.

摘要： A detecting apparatus for detecting a living body information includes a sensor body provided to contact a surface of a living body, and a band fixing bar elongated in a longitudinal direction, through which a band is engaged and is detachably connectable to the sensor body. In the detecting apparatus, the sensor body has a pair of holding portions for holding end portions of the band fixing bar in the longitudinal direction. The holding portion has an inlet concave portion from which the end portion of the band fixing bar is inserted, and a recess portion for receiving the end portion of the band fixing bar. Furthermore, the recess portion communicates with the inlet concave portion and recesses toward the living body, and the end portion of the band fixing bar is fitted into the recess portion. Therefore, the band fixing bar does not easily come off from the sensor body.

摘要： A biosensor senses pulse wave data of a user. The biosensor stores relation information, which indicates a relationship between recommended bedtime data and sleep-affecting activity data. The relationship between the recommended bedtime data and the sleep-affecting activity data is determined in view of at least one of previously sensed pulse wave data of the user and model pulse wave data. The biosensor receives at least one sleep-affecting activity value from the user. The biosensor computes recommended bedtime information based on the at least one sleep-affecting activity value in view of the relation information. The biosensor gives notification to the user based on the recommended bedtime information.

摘要： A wakefulness maintaining apparatus includes an event detecting part, a drowsiness level determining part, a threshold setting part, and a stimulus supplying part. The event detecting part detects an event related to a drowsiness of a person. The drowsiness level determining part determines a drowsiness level that changes in accordance with a strength of the drowsiness. The threshold setting part sets a threshold value to divide the drowsiness level into a first level range and a second level range in such a manner that the first level range is equal to or lower than the threshold value and the second level range is higher than the threshold value. The stimulus supplying part supplies a stimulus having an awaking effect to the person when the drowsiness level is in the second level range and the event is detected.
