A new safety and life support system has been developed to detect emergency situations of solitary-living elderly persons. The system employs a dual axis accelerometer, two low-power active filters, a low-power 8-bit single chip microcomputer and a personal handy phone. Body movements due to walking, running and posture changes are detected by the dual axis accelerometer and sent to the microcomputer. If the patient is in an inactive state for 5 minutes after falling, or for 64 minutes without previously falling, then the system automatically alarms the emergency situation, via the personal handy phone, to the patient's family, the fire station or the hospital.
一种新的安全与生命支持系统已被开发出来，用于检测独居老年人的紧急情况。该系统采用了一个双轴加速度计、两个低功耗有源滤波器、一个低功耗8位单片机和一部个人手持电话。双轴加速度计检测因行走、跑步和姿势变化而产生的身体运动，并将其发送到微电脑。如果患者跌倒后处于非活动状态5分钟，或者在未跌倒的情况下处于非活动状态64分钟，那么系统就会通过个人手持电话自动向患者家属、消防站或医院报警，告知紧急情况。
