20090187338 | Automatic Alerting Method and System for Aerial Vehicle Target Tracking - This invention provides a system and method for automatically inferring when a target that is being tracked by an aerial vehicle is doing something significant (e.g. stopping suddenly, changing direction quickly or getting out of track view), and consequently alerting an operator. The alerting system also provides a classification of what the target is doing. It frees the operator from continuously monitoring the imagery stream so the operator can perform other tasks. | 07-23-2009 |

20090187299 | Method and System for Autonomous Tracking of a Mobile Target by an Unmanned Aerial Vehicle - This invention provides a system and method for autonomously tracking a moving target from unmanned aerial vehicles (UAVs) with a variety of airframe and sensor payload capabilities so that the target remains within the vehicle's sensor field of view regardless of the specific target motion patterns. The invention uses information about target location, UAV platform type and states, sensor payload capability, and ratio of target-to-UAV speeds to select from a suite of sub-algorithms, each of which generates desired platform positions (in form of waypoints) and/or sensor orientation commands to keep the target in view. | 07-23-2009 |

20090088916 | METHOD AND SYSTEM FOR AUTOMATIC PATH PLANNING AND OBSTACLE/COLLISION AVOIDANCE OF AUTONOMOUS VEHICLES - Method and systems of traversing through a domain is provided. One method comprises getting a set of widely spaced waypoints, assigning the next waypoint to be the goal, then using a Laplacian path planner to construct a desired finely detailed path towards the goal, through the domain that avoids boundaries and objects in the domain. Assigning a potential value of v(r)=0 for r on boundaries and obstacles. Assigning a potential value of v(r)=−1 for r on a goal region, wherein the goal is a point on a planned path. Obtaining a numerical solution to the desired path with a Laplace's equation by gridding up the domain with a multi-sized cell grid, wherein the cells near an object are denser then the cells away from the objects. Iteratively setting a potential at each interior point equal to the average of its nearest neighbors and following the numerical solution provided by the Laplace's equation to the goal region. | 04-02-2009 |
20090319112 | AUTOMATIC PLANNING AND REGULATION OF THE SPEED OF AUTONOMOUS VEHICLES - An autonomous vehicle comprises one or more sensors configured to obtain data regarding conditions which affect movement of the autonomous vehicle; a speed planner coupled to the one or more sensors and configured to calculate a desired speed based, at least in part, on the data obtained from the one or more sensors; and one or more actuators responsive to signals from the speed planner and configured to adjust the speed of the autonomous vehicle based on the desired speed calculated by the speed planner. | 12-24-2009 |
