  • Patent number: 11155258
    Abstract: A risk maneuver assessment system and method to generate a perception of an environment of a vehicle and a behavior decision making model for the vehicle; a sensor system configured to provide the sensor input in the environment for filtering target objects; one or more modules configured to map and track target objects to make a candidate detection from multiple candidate detections of a true candidate detection as the tracked target object; apply a Markov Random Field (MRF) algorithm for recognizing a current situation of the vehicle and predict a risk of executing a planned vehicle maneuver at the true detection of the dynamically tracked target; apply mapping functions to sensed data of the environment for configuring a machine learning model of decision making behavior of the vehicle; and apply adaptive threshold to cells of an occupancy grid for representing an area of tracking of objects within the vehicle environment.

  • Publication number: 20060063490
    Abstract: A digitally controlled media multicasting system containing a signal processing system accepting and optionally modifying one or more independent single- or multi-channel baseband signals (typically, but by no means necessarily, audio or video signals); amplitude-, frequency-, or phase-modulating specified RF, IF, or LF carrier wave(s) in accord with said baseband signal(s); and then compositing the modulated carrier waves into a smaller quantity of waveform(s), said waveform(s) being (as necessary) frequency-multiplied or -shifted, and amplified for wireless transmission.
