  • Patent number: 11398954
    Abstract: Embodiments include devices and methods for managing network communication of an unmanned autonomous vehicle (UAV). A processor of the UAV may determine an altitude of the UAV. The processor may optionally also determine a speed or vector of the UAV. Based on the determined altitude and/or speed/vector of the UAV, the processor may adjust the communication parameter of the communication link between the UAV and a communication network. The processor may transmit signals based on the adjusted communication parameter, which may reduce radio frequency interference caused by the transmissions of the UAV with the communication network.

  • Patent number: 10126722
    Abstract: Various embodiments involve dynamically controlling parameters for processing sensor data, including rates at which vehicle sensors are sampled and analyzed, based on the vehicle's speed and direction. Data or sampling rates of sensors useful for collision avoidance and/or path planning may be adjusted to emphasize data from sensors having a field of view encompassing the travel direction, while limiting processing of data from sensors less likely to provide useful data for such purposes. In some embodiments, the rate at which data from a particular sensor is sampled and/or processed may depend on a vehicle's direction and speed of travel as well as the sensor's field of view. Processing demands may be reduced by focusing processing on data from sensors viewing the direction of travel while reducing processing of data from sensors viewing other directions. In some embodiments, sensor data sampling or processing rates may vary based on collision risk probabilities.

  • Publication number: 20180032042
    Abstract: Various embodiments include dynamically controlling one or more parameters for obtaining and/or processing sensor data received from a sensor on a vehicle based on the speed of the vehicle. In some embodiments, parameters for obtaining and/or processing sensor data may be individually tuned (e.g., decreased, increased, or maintained) by leveraging differences in the level of quality, accuracy, confidence and/or other criteria in sensor data associated with particular missions/tasks performed using the sensor data. For example, the sensor data resolution required for collision avoidance may be less than the sensor data resolution required for inspection tasks, while the update rate required for inspection tasks may be less than the update rate required for collision avoidance. Parameters for obtaining and/or processing sensor data may be individually tuned based on the speed of the vehicle and/or the task or mission to improve consumption of power and/or other resources.
