已经开发出一种系统来测量行走时手杖与地面之间的垂直力。当施加的力不在预先确定的范围内时，会发出音频警报。该系统采用两种类型的传感器连接到手杖上，一个力感应电阻（FSR, Interlink, Santa Barbara， CA.）和一个应变计桥（mlcromeasurement Group, ralligh， NC.）。传感器为便携式数据采集电路提供输入，该电路设计用于进行模数转换，并使用8称为查找表存储力数据。告警是根据查表值的值来控制的。告警阈值设置为使用前输入系统的受试者体重的比例。
A system has been developed to measure vertical forcer between a cane and ground while walking. An audio alarm sounds when applied forcer are not within pre-determined limits. The system employs two types of sensors attached to the cane, a force sensing reristor (FSR, Interlink, Santa Barbara, CA.) and a strain gage bridge (Mlcromeasurementa Group, Rallegh, NC.). The sensors provide Input to the portable data acquisition circuit which I8 derigned to perform analog to digital conversion and store the force data using 8 callbreted look-up table. The alarm is controlled on the baris of look-up table values. Thresholds for the alarm are set as a ratio of subject weight which 1s input to the system prior to use.
