Abstract
We measured lower limb activity by means two, above each ankle vertically aligned GT3X+ accelerometers in 4 healthy adults during a single night. Triaxial raw data vector magnitude units (VMU) were recorded at 100 Hz, in order to compare two different modes of operation (i.e. low power mode (LPM)on vs. off).
摘要
我们在4名健康成年人的一个夜晚期间，通过在每个脚踝上方垂直对齐的两个GT3X+加速度计测量下肢活动。以100赫兹记录三轴原始数据矢量幅度单位（VMU），以便比较两种不同的操作模式（即低功耗模式（LPM）开启与关闭）。
