Abstract: In one embodiment, an emergency vehicle detection system can be provided in the ADV travelling on a road to detect the presence of an emergency vehicle in a surrounding environment of the ADV using both audio data and visual data. The emergency vehicle detection system can use a trained neutral network to independently generate a detection result from the audio data, and use another trained network to independently generate another detection result from the visual data. The emergency vehicle detection system can fuse the two detection results to determine the position and moving direction of the emergency vehicle. The ADV can take appropriate actions in response to the position and moving direction of the emergency vehicle.

Abstract: A terahertz graphene Josephson junction detection system based on readout of a microwave resonant circuit includes a graphene Josephson junction detector, a microwave resonant readout circuit, and a microwave network analyzer. The graphene Josephson junction detector and the microwave resonant readout circuit form a microwave resonant circuit. A terahertz signal causes a change of an equivalent microwave inductance of the graphene Josephson junction detector, such that a resonant frequency and a quality factor of the microwave resonant circuit are changed. The present disclosure monitors the resonant frequency and the quality factor of the microwave resonant circuit with the microwave network analyzer, thereby realizing high-sensitivity detection on the terahertz signal. Compared with conventional direct-current (DC)-biased readout, readout of the microwave resonant circuit is not interfered by an external magnetic field, and has a strong interference resistance.
