Abstract: There is provided a system architecture including a PPG hardware module and a MEMS hardware module. The PPG hardware module processes PPG raw data, which is generally composed of analog signals or digital signals. The PPG hardware module filters the raw data for later digital calculation to, for example, find out frequency signals with higher peak values. The PPG hardware module then outputs the selected frequency signals to an MCU for heart rate calculation. The MEMS hardware module receives MEMS raw data from a motion detector made of MEMS elements. The MEMS raw data represents motion status of a user that could possibly affect the heart rate determination result. The MEMS hardware module filters the raw data for later digital calculation to find out frequency signals with higher peak values caused by motion.

Abstract: The present disclosure illustrates an optical navigation chip. The optical navigation chip is disposed on an optical navigation module. The optical navigation module includes a light-emitting unit. The light-emitting unit provides a light beam to irradiate a surface of a displacement generating unit. The light beam has a low divergence angle to reduce scattering. The optical navigation chip includes a sensing array and a displacement calculating unit. The sensing array is disposed corresponding to the surface. The sensing array receives a reflected light beam which the surface reflects, and captures an image once every capturing interval based upon the reflected light beam. The displacement calculating unit calculates a relative displacement between the optical navigation chip and the surface according to the images.
