A circuit for signal decoding in RFID or wireless power charging is provided in the present invention. The implement of the present invention is to add a current sense resistor connected to an upper switch or a lower switch the up arm switch or low arm switch to decode the signal on the current sense resistor. Since the error would occur in the original voltage decoder of the wireless power or RFID when the load is heavy and voltage signal swing is large, such that the charge status and then the off-line status cyclically occur and then the charge status . . . occurs in cycle when the mobile device is charging under charge. Since the present invention uses the voltage and current for decoding at the same time, the decoding would be succeed whenever the load is light or heavy.

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.
