Abstract
A locking system for securing an electronic device includes a locking signal transmitter anchored at a physical location away from the electronic device to transmit a locking signal. A receiver resides in the electronic device to receive the locking signal. A controller is coupled to the receiver and circuitry of the electronic device to virtually lock the electronic device at its location when the receiver keeps receiving the locking signal, and to disable the electronic device from being accessed after the receiver has stopped receiving the locking signal for a predetermined time period. The locking does not have any effect on functioning of the electronic device as long as the locking signal is received. When the device is unlocked, failure of the device lock to receive the locking signal also does not have any effect on the electronic device.
