摘要： Systems and methods for detecting symptoms of occupant illness is disclosed herein. In embodiments, a storage is configured to maintain a visualization application and data from one or more sources, such as an audio source, an image source, and/or a radar source. A processor is in communication with the storage and a user interface. The processor is programmed to receive data from the one or more sources, execute human-detection models based on the received data, execute activity-recognition models to recognize symptoms of illness based on the data from the one or more sources, determine a location of the recognized symptoms, and execute a visualization application to display information in the user interface. The visualization application can show a background image with an overlaid image that includes an indicator for each location of recognized symptom of illness. Additionally, data from the audio source, image source, and/or radar source can be fused.

摘要： A system and method is disclosed for determining a particular vehicle state based on a UWB signal received at a plurality of receiving nodes. A plurality of channel-impulse responses (CIRs) may be computed from the UWB signal received from the plurality of receiving nodes. A plurality of peak-based features based on a selected position and amplitude may be extracted from the plurality of CIRs. A plurality of correlation-based features may be generated by correlating the plurality of CIRs to a corpus of reference CIRs relating to a plurality of vehicle states. A plurality of maximum likelihood vehicle matrices may be generated by correlating the plurality of CIRs to the corpus of reference CIRs relating to the plurality of vehicle states. The vehicle state may then be determined by processing the plurality of peak-based features and correlation-based features using the machine learning classification algorithm.

摘要： A method relates to managing communications among a set of system nodes. The set of system nodes is configured to sense a predetermined region. The method includes establishing, via a processor, a schedule that includes a communication timeslot and a sensing timeslot, which are non-overlapping. A first system node or a second system node is operable to transmit a first message wirelessly during the communication timeslot. The second system node is operable to transmit a radar transmission signal during the sensing timeslot. The second system node is operable to receive a radar reflection signal during the sensing timeslot. The radar reflection signal is based on the radar transmission signal. The first system node or the second system node is operable to transmit a second message wirelessly during the sensing timeslot. The method includes determining channel state data of the second message via a subset of the set of system nodes during the sensing timeslot. The processor is operable to generate sensor fusion data based on the radar reflection signal and the channel state data. The processor is operable to determine a sensing state of the predetermined region based on the sensor fusion data.
