摔倒检测，可判断前摔，后摔，左摔，右摔，并用MATLAB界面实时显示。-Fall detection, can be determined before the fall, after the fall, fall left and right fall, and real-time display interface with MATLAB.

基于差分法的QRS波检测算法程序（PAN.J, TOMPKINS. W.J： A Real-Time QRS Detection Algorithm 对应的matlab程序）。-QRS detection algorithm program based difference method (PAN.J, TOMPKINS WJ:. " A Real-Time QRS Detection Algorithm" corresponding matlab program).
