Abstract: Provided herein are a measurement device and an operation method thereof. The measurement device senses a distance variation between the measurement device and an object using a built-in proximity sensor and accordingly determines whether to turn on or turn off a track sensing module and an optical ranging module such that the measurement device provides intelligent selection to achieve energy saving without being interfered with by other sensors being turned on.

Abstract: A VBI receiver and method is disclosed. The receiver includes an over-sampling circuit, a transition detector, a data selector, and a data output device. The over-sampling circuit is for over-sampling VBI data and outputting and over-sampled signal. The transition detector is for detecting the transition of the over-sampled signal and outputting a transition signal representing the transition position. The data selector is for recording the transition signal and outputting a position signal according to the transition signal and at least a previous transition signal. The data output device outputs digital output data from the over-sampled signal according to the position signal.
