Abstract: A wireless receiving apparatus and method utilizes a single MCU (microprocessor control unit) in the wireless receiver to receive and process signals having different frequencies transmitted from a plurality of peripheral devices simultaneously, and then performs the steps of reading a predetermined processing procedure from a memory with respect to each of the signals respectively, performing a predetermined process with respect to each of the signals, storing an index of the last finished step for each signal in the memory respectively after at least a set of steps of the predetermined process has been performed, and continuing to perform the steps following the indices of the previous set of steps stored in the memory for carrying out a next set of steps for each signal, and repeating a plurality of sets of steps until all received signals have been processed.

Abstract: The present invention relates a power saving mechanism in a cordless electronic device comprising a vibration sensor on a circuit board thereof having one end electrically coupled to an input pin of microprocessor on the circuit board and the other end electrically coupled to power supply of the circuit board. While the electronic device is inactive in a power saving mode, the electronic device can be activated through vibrating the electronic device, which enables the vibration sensor to be closed and the current of power supply to be supplied to the input pin via the vibration sensor to activate the microprocessor to change its logic level and activate all electronic components of the circuit board.

Abstract: A wireless apparatus includes a transmitter and a receiver wherein each of the transmitter and the receiver includes a phase-locked loop (PLL) having a frequency synthesizer for generating a plurality of signals with identifications. The plurality of signals are combined to form spread spectrum modulated signals prior to transmitting from the transmitter. Correspondingly, the received signals in the receiver are converted into the original signals by the frequency synthesizer. With this, it is impossible for an unauthorized party to copy such signals, thereby providing a safe wireless communication environment to the user.
