Abstract:
A communications apparatus is provided. A first wireless communications module provides a first wireless communications service and communicates with a first communications device in compliance with a first protocol. A second wireless communications module provides a second wireless communications service and communicates with a second communications device in compliance with a second protocol. A clock source is shared by the first and the second communications modules and provides a reference clock to the first and the second communications modules. The first wireless communications module detects a request from the second wireless communications module for activating the clock source, determines whether the reference clock has been stably generated by the clock source, and adjusts an electrical characteristic of the clock source to facilitate the reference clock output from the clock source to achieve a target frequency when the reference clock has not been stably generated.

Abstract:
An optical sensing device includes a shell, at least one light emitting member, a rotator type shading member and at least one optical sensing member. The shell is formed with a black-body condition space having a light emitting chamber, a shading chamber and at least one optical sensing chamber. The light emitting member projects a light beam. The rotator type shading member is rotatably restrained within the shading chamber, and has a geometric center and a weight center offset from the geometric center. When the optical sensing device is lifted in a lifting azimuth or lowered in a lowering azimuth, the rotator type shading member is rotated by the geometric center to make the weight center located in the lowering azimuth with respect to the geometric center. The optical sensing member is arranged in the optical sensing chamber, and senses the light beam to accordingly send out a sensing signal.
