Abstract: An RFID tag is attached to or embedded in an object and used for determining the position of the object. The RFID tag includes a controller and an energy harvester coupled to the controller. The controller provides object position information to a host device by sending ping signals to the host device. The energy harvester harvests RF energy from WLANs, converts the RF energy to DC power, and supplies the DC power to the RFID tag.

Abstract: Embodiments of a method and a device are disclosed. In an embodiment, a method for operating a radar system is disclosed. The method involves generating a chirp signal having a repeating pattern of chirps, each chirp in the repeating pattern of chirps having a base frequency and a chirp bandwidth, wherein the repeating pattern of chirps includes at least two chirps that differ from each other in at least one of base frequency and chirp bandwidth, transmitting a radar signal according to the chirp signal, receiving radio frequency energy that includes a reflected portion of the radar signal, and selecting for processing from the received radio frequency energy a signal that matches the repeating pattern of chirps of the chirp signal.

Abstract: An apparatus includes a processor configured to receive first sensor data from a sensor system of the first entity and a receiver. The receiver is configured to receive second sensor data from a second entity in the vehicle to vehicle network over a communication network and provide the second sensor data to the processor. The second sensor data comprises a first type of sensor data having a first bandwidth requirement. The processor is further configured to determine an available bandwidth of the communication system; and when the first bandwidth requirement exceeds the communication bandwidth, select a second type of sensor data having a second bandwidth requirement. The second bandwidth requirement is less than the first bandwidth requirement. The processor is further configured to process the first and second sensor data to at least partially determine an environment surrounding the first entity.
