Abstract: Information is acquired from a geographically-distributed sensor network using a scalable wireless geocast protocol. Geographically distributed networks of unattended sensors are placed at desired locations to collect various types of information, such as, for example, environmental parameters, temperature, humidity, rainfall, heat signatures, video, audio, seismic activity, and/or wind conditions. To acquire information, a query is provided to the geographic area at which the sensors are located utilizing the geocast protocol. Delivery of the query is based on a physical location of a region in which a sensor network is located, the type of information being queried, and/or temporal conditions. Each sensor that receives a query determines if all requirements/conditions are satisfied. If so, the query is accepted and processed by the recipient sensor, and responded to accordingly. Responses to queries are provided via the geocast protocol.

The processing circuitry further combines the first weighted synchronization signal and the second weighted synchronization signal to generate a combined synchronization signal.

The determined manner of the communication can be based on determining whether the mobile terminal faces a display screen of the display device for wirelessly transmitting the content data from the mobile terminal to the display device or determining whether the mobile terminal faces away from the display screen of the display device for wirelessly transmitting the content data from the display device to the mobile terminal.

Abstract: A wireless communication node (10) dynamically estimates passive intermodulation (PIM) interference coupled into the node's receive path from the transmission of a composite signal through the node's transmit path. The node (10) then cancels the estimated PIM interference in the receive path. In some embodiments, the node dynamically estimates the PIM interference as a function of the composite signal that models PIM interference generation and coupling in the node (10) according to one or more coefficients (30). The coefficients (30) may be determined by transmitting a test signal (34) during a test stage, when the node (10) is not scheduled to receive any signal. Later, when the composite signal (18) is transmitted, the node (10) uses the coefficients (10) to dynamically estimate and cancel the resulting PIM interference.
