In order to evaluate balancing ability in each direction more objectively and analyze the correlations between balance ability and human basic information such as gender, height and weight, the complete dynamics model of balance process under external excitation was simplified as two order linear system reasonably in this study. The evaluation system based on visual stimulation was built to provide...
The testing circuit of body noninvasive arterial oxygen saturation is designed according to the characteristics that the light absorption of arterial blood varies with pulse. The driving circuit of testing source and anti-Rossi circuit of compound signal are controlled by DSP sequence signal, and the sending of the testing signal is synchronous with the separation-receiving signal. The high frequency...
