Patent ID: 7496359

Claim:
A system for enabling a user to know the whereabouts of his or her missing mobile phone, the system comprising: a remote controller, including: at least one button adapted to be pressed to generate a control signal; a control circuit electrically connected to the button for receiving the control signal and being adapted to generate a search signal in response to the control signal; a first decoder electrically connected to the control circuit for receiving the search signal and being adapted to convert the search signal into a wireless search signal; a wireless transceiver unit electrically connected to the first decoder for receiving the wireless search signal and transmitting the wireless search signal to an external; and a first power supply electrically connected to the control circuit for supplying electric current thereto; and a mobile phone, including: a first control unit electrically connected to a plurality of output units thereof; a control module electrically connected to the first control unit and comprising: a wireless receiving unit adapted to wirelessly receive the wireless search signal generated by the remote controller; a second decoder electrically connected to the wireless receiving unit for receiving the wireless search signal and converting the wireless search signal into a search signal; and a second control unit electrically connected to the first control unit for receiving a power-on signal generated by the first control unit and generating a signal in response to the received power-on signal, wherein the second control unit is adapted to send a response signal representing the search signal to the first control unit, when the second control unit has received the search signal from the second decoder, so as to enable the second control unit to have a highest control priority than the first control unit for converting the search signal or response signal into a corresponding instruction signal and activating the output units connected thereto to generate a corresponding indication in response to the instruction signal; and a second power supply electrically connected to the first control unit and control module for supplying electric current thereto.
