    • A person support apparatus, such as a bed, stretcher, cot, recliner, or the like, includes an exit detection system having a plurality of force sensors that support the weight of an occupant positioned on a support surface. The force sensors are part of an exit detection system that issues an alarm when the occupant exits, or is about to exit, the person support apparatus. The distribution of weight applied to the force sensors is used to determine if the occupant is about to exit the person support apparatus. Compensation is made to the exit detection system for changes in the weight distribution that are not caused by movement of the occupant. Such changes may be due to siderail movement, support surface pivoting, and/or movement of other components of the person support apparatus.
    • 诸如床,担架,婴儿床,躺椅等人员支撑装置包括具有多个力传感器的出口检测系统,所述力传感器支撑位于支撑表面上的乘客的体重。 力传感器是出口检测系统的一部分,当乘客出现或即将离开人员支持设备时,出口检测系统发出警报。 应用于力传感器的重量分布用于确定乘员是否将要离开人员支撑装置。 补偿出口检测系统对重量分布的变化,而不是由乘员的移动引起的。 这种改变可能是由于人员支撑装置的侧轨运动,支撑表面枢转和/或其他部件的运动。
