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： Methods for operating real-time wireless networks enable robust medium access strategies for communicating nodes in the network. A given wireless channel is divided into several sub-carriers, with each node assigned to a subset of sub-carriers. A master wireless node uses different subsets of the sub-carriers to communication with two or more slave wireless nodes simultaneously. The method includes generation of preambles that are robust to interference and multipath conditions. The method also enables communication within a maximum predetermined latency bound.

摘要： In a wireless transmission system, a transmitter sends a plurality of data packets to a receiver. The transmitter identifies channel quality indicators corresponding to properties of a communication channel between the transmitter and the receiver. During operation, the transmitter adjusts one or more parameters that affect the Quality of Service (QoS) of data transmission between the transmitter and receiver to enable data transmission at different quality levels over a range of channel quality levels. In one embodiment, the transmitter sends data packets corresponding to video from a camera to the receiver.

摘要： An automotive communication method includes installing a sensor within a vehicle such that the sensor is submerged in a liquid during operation of the vehicle and/or substantially surrounded by a metallic structure during operation of the vehicle. A long wave magnetic signal is transmitted from the sensor. The signal is indicative of a condition sensed by the sensor. The signal is wirelessly received at a controller disposed within the vehicle. Receipt of the signal at the controller is responded to by adjusting a display and/or a setting within the vehicle.

摘要： A method for reprogramming a node of an electronic communication system includes transmitting a signal from a first node to a second node. The signal requests that the second node be reprogrammed. The signal includes an identification of the first node. The second node is used to broadcast the identification of the first node to other nodes in the communication system. The second node is reprogrammed only if a predetermined quantity of the other nodes confirm, based on the identification, that the first node is legitimate.
