A physiological data detection method is provided. The physiological data detection method includes the following steps. Firstly, an ECG signal and a PPG signal are detected. Then, a plurality of RRI values is calculated according to the ECG signal, and a plurality of PPI values is calculated according to the PPG signal. Thereafter, wrong RRI values are excluded according to the RRI values and/or the PPI values. Then, whether an abnormal state occurs or not is determined by using the remaining RRI values. A wearable device therefor is also provided.

Physiological data detection method and wearable device therefor

The present invention provides a method for controlling a focus speed of a pick-up head while performing a layer jump operation over a multi-layer optical disk in an optical information reproducing apparatus. The optical information reproducing apparatus includes the pick-up head, an actuator and a counter. The pick-up head has an objective lens positioned over a first focus of the multi-layer optical disk and in response to a signal reflected from the multi-layer optical disk, will generate a RF level signal and. The actuator is electronically connected to the pick-up head for driving the objective lens to perform the layer jump operation in response to a kick pulse signal. The counter generates a counter value in response to the kick pulse signal. The method comprises the steps of sending the kick pulse signal to the actuator for kicking the objective lens out of the first focus; processing the RF level signal and the counter value for generating a speed control data according to a predetermined procedure; and driving the objective lens to a second focus through the actuator in response to the speed control data.
