Abstract:
1. A wireless device comprising: a short-range transceiver for communicating with an auxiliary device; a signal module for providing a mode control signal; and, a control module for controllably shifting the short-range transceiver between a power saver mode and a search mode based on the mode control signal received from the signal module; wherein, when in the search mode, the short-range transceiver is operable to search for the auxiliary device to communicate therewith, and when in the power saver mode, the short-range transceiver is inactive and not operable to search for the auxiliary device; the signal module comprises a detector for detecting when the auxiliary device is in close proximity, the signal module being operable to send a first signal when the detector detects that the auxiliary device is in close proximity and a second signal when the detector detects that the auxiliary device is not in close proximity; and the control module is operable to shift the short-range transceiver
