    • A bed apparatus having an off-bed prediction/detection system for enabling the movement of the user to be accurately monitored by judging information including a combination of the weight information and center-of-gravity information on the user, reducing erroneous reports of off-bed detection, and having a high reliability. The bed apparatus comprises load measuring sections (3-1, 3-2, 3-3, 3-4) generating a load signal by detecting the load on the bed part (1), a body weight computing section for computing the body weight of the user present on the bed part (1) from the load signal, a first judging section for judging whether or not the body weight is a predetermined threshold or less, a center-of-gravity position computing section for computing the position of the center of gravity of the user from the load signal, and a second judging section for judging whether or not the position of the center of gravity is within a monitoring object area of the bed part (1). If the first judging section judges that the body weight is the predetermined threshold or less and the second judging section judges that the position of the center of gravity is within the monitoring object area, the bed apparatus detects the state of the user. ® KIPO & WIPO 2009
    • 一种具有离床预测/检测系统的床装置,用于通过判断包括重量信息和重心信息的组合的信息来使用户的移动能够被准确地监视,从而减少了错误的报告, 床检测,并且具有高可靠性。 床装置包括通过检测床部分(1)上的负载产生负载信号的负载测量部分(3-1,3-3,3-3,3-4),用于计算体重的体重计算部分 由负载信号存在于床部分(1)上的用户,用于判断体重是否为预定阈值的第一判断部分,用于计算体重的位置的重心位置计算部分, 以及用于判断重心的位置是否在床部(1)的监视对象区域内的第二判断部。 如果第一判断部判定体重是预定阈值以下,第二判断部判定重心位置在监视对象区域内,则床装置检测用户的状态。 ®KIPO&WIPO 2009
