<p><P>PROBLEM TO BE SOLVED: To provide a bed apparatus equipped with an abnormal position judgement or rising detection system more accurately monitoring the movement of a user and highly reliably monitoring the movement of the user with less erroneous detection and high detection accuracy by judging information in which the weight information and centroid position information of the user are combined. <P>SOLUTION: When a weight range judgement part judges that the weight of the user on a bed is within a prescribed range and a centroid position area judgement part judges that the centroid position has moved to an abnormal position (monitoring object area), when a weight and centroid position monitoring part detects that the state continues for the prescribed time or longer, it is detected that the bed user is at the abnormal position. <P>COPYRIGHT: (C)2008,JPO&INPIT</p> |
