Sleep detecting apparatus |
摘要 |
Movement of a person in bed is detected without contacting the body, and time measurement is reset and started newly by a timer every time a detected movement exceeds a predetermined set value. When the measurement time of the timer exceeds a set time predetermined, it is judged that the body has fallen asleep on the bed. Meanwhile, absence or presence in bed and rough body movement are judged by detecting the fine body movement propagated by the functioning of heart and breathing of the body.
