A security method for monitoring an optical module and a three-dimensional sensor using the same apply electromagnetic induction to the three-dimensional sensor to monitor the optical module and a light source module. Two inductive coils corresponding to each other are arranged on the light source module and the optical module. An alternative current is inputted to one of the inductive coils and another of the inductive coils generates an inductive current. The value of the inductive current is continuously detected. When the value of the inductive current varies, the abnormality of the optical module is determined to shut down the light source module, thereby completing the security mechanism of the three-dimensional sensor.

A control method and system for filtering power line interference is disclosed. The control method includes the following steps. First, ECG signals are pre-segmented and rectified; then the sinusoidal frequency, amplitude, and phase of the rectified segmented signals are extracted. These estimated sinusoidal parameters from each recorded channel are weighted by their individual signal to noise ratios before being averaged to achieve the optimal powerline frequency, amplitude, and phase. Based on these optimal sinusoidal parameters, the individual sinusoidal waveform is reconstructed and then is subtracted from the corresponding ECG segment, in order to obtain the clean ECG signals. This method of filtering the powerline interference through removal from recorded signals enables accurate measurement without any ringing effect that could lead to signal distortion issues. Thus this invention solves the ringing problem encountered by traditional notch filter techniques when signal amplitude suddenly changes in a measurement.
