Patent ID: 8274255

Claim:
A multi-function remote control which is supplied power by a rechargeable battery, the multi-function remote control comprising: a micro controller unit (MCU) coupling to the rechargeable battery and then charging or discharging the rechargeable battery; a residual power display; a button unit including pluralities of functional buttons, the functional button outputting a functional signal (S func ) to the MCU when the functional button is pressed; a remote control transmitter transmitting encoded infrared signal by means of the control of the MCU when the MCU receives the functional signal (S func ); a current detector measuring the current of the rechargeable battery and correspondingly outputting a current-value signal (S i ) to the MCU; a voltage detector measuring the voltage of the rechargeable battery and correspondingly outputting a voltage-value signal (S v ) to the MCU, the MCU obtaining the residual power of the rechargeable battery by means of analyzing the current-value signal (S i ) and voltage-value signal (S v ), and then revealing the corresponding residual power by the residual power display; at least one detachable connector coupling to the MCU, the MCU charging the rechargeable battery when the detachable connector is connected to external power supply; whereby, the multi-function remote control might have functions of remote control, charging and revealing residual power.
