Abstract:
The present invention relates to a position identification system and a method for gesture identification thereof. The method for gesture identification does not use the conventional digital image capture method, instead, the method uses IR detection. In order to accurately detect the movement track of the external object, in the present invention, at least two IR LED are provided. When the first IR LED emits the IR ray signal, the second IR LED is used for receiving IR ray signal. Moreover, the present invention determines the distance between the external object and the IR LEDs by detecting the emitting IRs with different energy. Further, the present invention adopts TDM (Time Division Multiplexing) such that the present invention can grasp the distance between the first IR LED and the external object and the distance between the second IR LED and the external object. Thus, the relative position of the external object can be captured.

A decoder for a wireless charging transmitter and a wireless charging transmitter using the same are provided in the present invention. In order to adapt the wide range of the received signal from the wireless charging receiver, which usually results in the error of the decode, the feedback circuit of the wireless charging transmitter is changed, so that the signal in a certain swing is amplified by an original gain, and the signal out of the certain swing is amplified by a limited gain. Therefore, the amplified signal is able to show the characteristic of the original received signal. Thus, the accuracy of decoding is increased.
