Abstract: Disclosed herein are a system and a method for controlling a rear vision assembly (RVA) of a vehicle, the system comprising a sender, receivers, an orientation device, a controller, and a motor. At least one said receiver disposed at the RVA may receive a reference signal from the sender to generate a relative positioning signal. The orientation device, disposed at the RVA, senses the orientation thereof in the three-dimensional space. Based on the relative positioning signal, the controller determines a relative position of the RVA and the sender and compares it with a default relative position, in addition to comparing the sensed orientation with a default orientation, thus generating a driving signal that directs the motor to restore the RVA to its default configuration when the determined relative position has deviated from the default for a predefined time and the sensed orientation deviates from the default.

Abstract: An electronic device of preventing poor heat dissipation and having ESD protection and a protection method for the electronic device are disclosed, in which the electronic device includes a main body, an outer covering, a processing unit and a protective device. The processing unit and the protective device are disposed in the main body. The protective device is coupled to the processing unit. When the outer covering and the main body are closed tightly, the protective device can send a warning signal to the processing unit.

Abstract: A method of detecting a vehicle speed is disclosed in the present invention. The method includes outputting a detecting wave, receiving a reflecting wave from an external object when the external object passes through a covering range of the detecting wave, calculating a variation between the detecting wave and the reflecting wave, and reading a table for executing an application program according to information of the table.
