摘要： The present invention relates to a voltage detecting circuit for detecting a voltage range of a power source. The voltage detecting circuit includes a micro controlling unit, a boost circuit and a plurality of divider resistors. The micro controlling unit includes a general input/output port and a controlling input/output port. The boost circuit provides a constant voltage. A judgment voltage is obtained according to the divider resistors, the constant voltage and a voltage of the power source. A digital level signal is issued by the general input/output port according to the judgment voltage. In response to the digital level signal, the micro controlling unit generates a corresponding prompt associated with the voltage status of the power source.

摘要： The present invention provides a channel switching method for use with a wireless mouse by intelligently switching the communication channels with a wireless signal receiver. Firstly, the packet error rate is detected to discriminate whether the number of continuous failed packets is greater than a threshold value. Subsequently, the received signal strength indicator (RSSI) is detected to discriminate whether the wireless transmitter needs to switch the current communication channel with the wireless signal receiver.

摘要： An illumination control device is used in an optical pointer to cooperate with an optical sensor module and a light-emitting device to emit proper illuminance of light. The illumination control device includes a microcontroller generating a supplemental current when the optical pointer is in a power-saving state; and a controlled current amplifier in communication with the microcontroller, the optical sensor module and the light-emitting device for providing an amplified current for the light-emitting device to emit light. The controlled current amplifier amplifies a synthesized current of a light-emitting current generated by the optical sensor module and the supplemental current generated by the microcontroller to obtain the amplified current when the optical pointer is in the power-saving state.

摘要： A multi-mode computer pointer includes a main body, a function switch disposed on the main body and triggered to switch the computer pointer between a first mode and a second mode, and a command generator in communication with the function switch and a computer, triggered in a manner to generate a cursor control command to the computer in the first mode and triggered in the same manner to generate a non-cursor control command to the computer in the second mode. The non-cursor control mode, for example, is for controlling windows media player.
