Cordless remote control apparatus
摘要:
A cordless remote control apparatus has a controlled portion adapted to a main body and a control unit cordlessly or wirelessly coupled to the controlled portion. The control unit contains an instruction transmitter for generating an instruction wave. The main body contains a device which is actuated according to the instruction wave wirelessly transmitted from the control unit to the controlled portion. The controlled portion includes an instruction receiver for generating a receiving indication signal when the instruction receiver is coupled to the instruction transmitter via the instruction wave, and providing the device with a control command corresponding to the contents of the instruction wave. The control command determines the actuation of the device. The controlled portion further includes a confirmation transmitter coupled to the instruction receiver for generating a confirmation wave for a given period of time after the receiving indication signal disappears and control command is generated. The control unit includes a confirmation receiver cordlessly or wirelessly coupled to the confirmation transmitter via the confirmation wave for indicating in accordance with the confirmation wave the establishment of actuation of the device.
