  • Patent number: 8106822
    Abstract: A Global Navigation Satellite System (GNSS) device, such as the Global Positioning System (GPS) device, uses satellite orbital position information from almanac and/or ephemeris data to change a search parameter, such as reducing the number of analyzed frequency bins or setting signal strength threshold, so that satellite signal acquisition times are reduced. An exemplary embodiment estimates an orbital position for at least one GNSS satellite based upon at least one of almanac data and ephemeris data, detects a signal emitted from the at least one GNSS satellite, and based upon the estimated orbital position information for the at least one GNSS satellite that is determined from the almanac data and the ephemeris data, adjusts at least one parameter used in the analysis of the detected signal.

  • Patent number: 8078399
    Abstract: An obstacle-avoidance-processor chip for three-dimensional path planning comprises an analog processing circuit and at least two analog-resistive-grid networks. The analog processing circuit is communicatively coupled to receive data from an inertial measurement unit and from at least one obstacle-detection sensor. The analog processing circuit is configured to construct a three-dimensional obstacle map of an environment based on the received data. The at least two analog-resistive-grid networks are configured to map obstacles in at least two respective non-parallel planes in the constructed three-dimensional obstacle map. The at least two analog-resistive-grid networks form a quasi-three-dimensional representation of the environment. The obstacle-avoidance-processor chip generates information indicative of a three-dimensional unobstructed path in the environment based on the obstacle maps.

  • Patent number: 7907750
    Abstract: A system for autonomous object tracking with static camera arrangements. Each camera arrangement may minimally have a pan-tilt-zoom camera and a range or depth sensor. Imaging may provide coordinates and depth information of a tracked object. Measurements of an image centroid position and width may be obtained with processing. Maintaining an image at the center of a camera screen may be attained at a pixel width of the image. Estimation and prediction of object size and position may be processed for providing pan, tilt and zoom rates for the camera. Pan, tilt and zoom latency may be accounted for in the system. There may be a number of camera arrangements where tracking of the object may be handed off by one camera arrangement to another.

  • Patent number: 7765062
    Abstract: A method and system for autonomous tracking of a mobile target such as a ground vehicle by an unmanned aerial vehicle are provided. The method and system utilize an approach that tracks a mobile ground target by using a ground vehicle model with an ummanned aerial vehicle model, with velocity and acceleration constraints. These real-world constraints ensure that the method is applicable to a general class of unmanned aerial vehicles and ground targets. One or more sensors are employed on the unmanned aerial vehicle, with the sensors having at least one field-of-view sensing cone over the ground. A position and path of the mobile target are monitored through input from the sensors on the unmanned aerial vehicle. The method and system detect and estimate the position and path of the mobile target when the target is inside the field-of-view sensing cone.

  • Publication number: 20100121574
    Abstract: A method for collision avoidance of an unmanned aerial vehicle (UAV) with other aircraft such as manned aircraft or another UAV is provided. The method comprises detecting an aircraft approaching a flight path of an unmanned aerial vehicle, and estimating a position, range, and velocity of the aircraft. An estimated path of the aircraft is determined from the position, range, and velocity. A new flight path is then calculated for the unmanned aerial vehicle to a waypoint to avoid the estimated path of the aircraft.

  • Patent number: 7580812
    Abstract: A trending system and method for trending data in a mechanical system is provided. The trending system includes a sliding window filter. The sliding window filter receives a data set of data points generated by the mechanical system. The sliding window filter partitions the data set into a plurality of data windows, and uses the data windows to calculate upper and lower confidence bounds for the data set. Specifically, the sliding window filter calculates an upper confidence bounds and lower confidence bounds for each data point using each of the multiple data windows that includes the data point. The sliding window filter then selects the upper confidence bounds and the lower confidence bounds that results in the smallest mean prediction confidence interval for that data point. This results in a smoothed estimated trend for the data set that can be used for prognostication and fault detection.
