Abstract: A method for correcting an angle sensor is applied to a step motor including an angle sensor, where the angle sensor rotates with the step motor, and the method for correcting an angle sensor includes the following steps: rotating the step motor by a preset angle to a first position; reading a first voltage of the angle sensor when the angle sensor is rotated to the first position; determining whether the first voltage deviates from a preset voltage curve; if yes, recording a first offset of the first voltage relative to the preset voltage curve; and compensating for a sensing angle of the angle sensor according to the first offset. A device for correcting an angle sensor is further provided.

Abstract: An anti-counterfeit method for assisting in face recognition includes the following steps: capturing a dynamic image of an object; filtering a plurality of time-varying signals from the dynamic image to obtain a plurality of filter signals; and comparing the filter signals and preset biological information that corresponds to the object, to output a determining result. When the dynamic image of the object is captured, according to this method, at least one region is interest is set in the dynamic image, and each time-varying signal corresponds to a time-varying gray-scale value of at least one pixel of the dynamic image in the region of interest. An anti-counterfeit system is also provided.

Abstract: A voice control device includes a user database, a first image capturing module, a voice command module and a management module. The user database stores first user identification data of a first user account. The first image capturing module captures an environmental image. The voice command module is enabled to receive a voice command for controlling the voice control device. The management module is used to detect whether at least one facial image exists in the environmental image, and detect whether the facial image matches with the first user identification data, and when the facial image matches with the first user identification data, the management module logs in the first user account and enables the voice command module.
