Abstract: The invention relates to a sensor (300) for determining a dielectric property of a medium (205). The sensor (300) has a substrate (301, 302), which has at least one via (203, 204), and a waveguide (12), which is arranged so as to be planar in relation to an upper surface of the substrate (301). The waveguide (12) can be connected to an analysis device (20) by means of the at least one via (203, 204). Furthermore, the waveguide (12) is designed to receive an input signal from the analysis device (20) and to output an output signal to the analysis device (20). When of the waveguide (12) is in contact with a medium (205), properties of the input signal and of the output signal are indicative of the dielectric property of the medium (205). The arrangement of the waveguide (12) so as to be planar in relation to the substrate (301) enables larger measurement ranges and improved measurement accuracies. Furthermore, a compact construction is achieved by the planar structure.

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.
