Abstract:
1. A communication device configured to selectively enter one of an activated state and a deactivated state comprising: a reception device for detecting a signal; and a plurality of components configured for selective activation; wherein the communication device, while in the deactivated state, performs periodic self-polling using the reception device, and the communication device directly enters the activated state based upon the results of the periodic self-polling; wherein the communication device, while in the activated state selectively activates a first set of components, consisting of one or more of the plurality of components, to receive time information associated with the transmission of useful information to the communication device; wherein the communication device selectively deactivates one or more of the plurality of components for a period of time based upon the time information received after which the communication device selectively activates a second set of components prior to the transmission of the useful information to the communication device; and wherein the second set of components consists of one or more components not within the first set of components.
