Abstract: A Bluetooth-enabled infrared (IR) remote control is disclosed, which comprises: a micro control unit, for executing operations of signal processing, decoding and encoding; an signal amplifying circuit, for amplifying a control signal being issued and coded by the micro control unit to be used for controlling a corresponding function of a specific electronic device; an infrared light emitting diode (IRLED), capable of issuing an infrared signal; and a Bluetooth module, capable of communicating with a bluetooth-enabled electronic device by Bluetooth wireless transmission while passing data received from the bluetooth-enabled electronic device to the micro control unit where it is processed.

Abstract: A hands-free switching device is adapted for use with a mobile telephone in a car having an audio output unit and a loudspeaker unit. The hands-free switching device includes a switch unit, a switch driver, and a driver control unit. The switch unit is capable of being switched to one of an activated position, where the switch unit electrically interconnects the mobile telephone and the loudspeaker unit to enable speech signals from the mobile telephone to be reproduced at the loudspeaker unit, and a deactivated position, where the switch unit electrically interconnects the audio output unit and the loudspeaker unit to enable audio signals from the audio output unit to be reproduced at the loudspeaker unit. The switch driver is associated operably with the switch unit and is capable of being enabled so as to control the switch unit to operate from the deactivated position to the activated position.
