Abstract
A communication system is enclosed. In one embodiment, the communication system includes a communication device configured to puts itself into an activated state or into a deactivated state at alternate times. The communication device receives time information in a first operating state of the activated state, takes the received time information as a basis for ascertaining the later time at which useful information is transmitted to the communication device, receives the useful information at the later time in a second operating state of the activated state, and with individual components of the communication device being able to be put into an activated state or into a deactivated state independently of one another.
Claims25
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.
A communication system comprising:
- a communication device comprising:
- a reception device for detecting a signal;
- and
- a plurality of components configured for selective activation;
- and
- a control apparatus for communication with the at least one communication device configured to transmit time information and useful information to the communication device at alternate times, the time information being able to be taken as a basis for ascertaining the later time at which useful information is transmitted;
- 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.
