    • A wireless monitoring/assessment system identifies and records selected basic activities of daily living, loss of balance, and falls of at-risk elderly using a minimum set of sensors. A wearable system collects data over an extended period from sensors mounted under each shoe/slipper inner sole, and three kinetic measurement sensors, one mounted on the subject's chest, and the other two on each thigh. The resulting data can be processed off line to determine if a loss of balance or fall has occurred and identify the basic activity that the subject was performing when it happened. The two inner sole foot pressure sensors provide data on the loading of the plantar aspect of each fore- and rear foot. Each kinematics measurement sensor module provides 3-axis acceleration and angular rate data from the torso and each thigh. All data is sampled at a high rate using an analog to digital converter, time stamped, and then stored in memory.
    • 无线监控/评估系统使用最少的传感器来识别和记录选定的日常生活基本活动,失去平衡和危险的老年人跌倒。 穿戴式系统可以在安装在每个鞋/拖鞋内底下的传感器和三个动力学测量传感器,一个安装在被检者的胸部上,另外两个在每个大腿上收集数据。 得到的数据可以离线处理,以确定是否发生了平衡或掉落的损失,并确定了发生事件时受试者执行的基本活动。 两个内底脚压力传感器提供每个前脚和后脚的足底方面的装载数据。 每个运动学测量传感器模块提供来自躯干和每个大腿的3轴加速度和角速率数据。 使用模数转换器,以高速率对所有数据进行采样,时间戳,然后存储在存储器中。
