Patent ID: 7774015

Claim:
A wireless personal area network (WPAN) host device, comprising: a WPAN module configured to receive WPAN information from a WPAN information source; an on/off control module coupled to the WPAN module for switching the host device between an on state in which WPAN information can be received by the WPAN module and an off state in which WPAN information can not be received by the WPAN module; and a power control module coupled to the on/off control module, wherein the power control module includes a controller coupled to the on/off control module, wherein the controller is configured to receive at least one WPAN command from the WPAN information source, and a power source coupled to the controller for supplying power to the controller, wherein, when the controller receives at least one WPAN command from the WPAN information source, if the WPAN information source has a WPAN master/slave relationship with the host device, and if the host device is in the off state, the controller instructs the on/off control module to switch the host device to the on state wherein the WPAN module can begin receiving WPAN information from the WPAN information source.
