<P>PROBLEM TO BE SOLVED: To precisely inform starting of rising motion of a carereceiver in advance. <P>SOLUTION: A handrail sensor 21 is mounted on a handrail of a bed and detects whether the handrail is drawn to the front by the carereceiver in accordance with a sensor value provided from the handrail sensor 21. Additionally, a center-of-gravity sensor 31 is mounted on the bed, and a center-of-gravity position on the bed of the carereceiver is computed from the sensor value provided from the center-of-gravity sensor 31. Thereafter, it is informed that rising is started when it is judged that the handrail is drawn to the front and that the center-of-gravity position is included in a getting-up estimated region estimated as positioned in starting getting-up. <P>COPYRIGHT: (C)2008,JPO&INPIT |
