| 20120083959 | DIAGNOSIS AND REPAIR FOR AUTONOMOUS VEHICLES - A system and method of controlling a vehicle is provided. In one aspect, the system and method determines the amount of wear on a component of the vehicle and, based on the amount of wear and information derived from the environment surrounding the vehicle (e.g., another vehicle in the path of the vehicle or a requirement to stop at a particular location), maneuvers the vehicle to mitigate further wear on the component. | 04-05-2012 |
| 20120083960 | SYSTEM AND METHOD FOR PREDICTING BEHAVIORS OF DETECTED OBJECTS - Aspects of the invention relate generally to autonomous vehicles. Specifically, the features described may be used alone or in combination in order to improve the safety, use, driver experience, and performance of these vehicles. | 04-05-2012 |
| 20120083964 | ZONE DRIVING - A roadgraph may include a graph network of information such as roads, lanes, intersections, and the connections between these features. The roadgraph may also include one or more zones associated with particular rules. The zones may include locations where driving is typically challenging such as merges, construction zones, or other obstacles. In one example, the rules may require an autonomous vehicle to alert a driver that the vehicle is approaching a zone. The vehicle may thus require a driver to take control of steering, acceleration, deceleration, etc. In another example, the zones may be designated by a driver and may be broadcast to other nearby vehicles, for example using a radio link or other network such that other vehicles may be able to observer the same rule at the same location or at least notify the other vehicle's drivers that another driver felt the location was unsafe for autonomous driving. | 04-05-2012 |

| 20090105939 | VEHICLE NAVIGATION SYSTEM WITH OBSTACLE AVOIDANCE - A vehicle navigation system through an area having a plurality of objects. A Voronoi decomposition on the area is first constructed having a number of edges surrounding the obstacles. A Voronoi field having a value between zero and an upper limit is calculated for geometric locations within the area such that the field reaches a maximum value within obstacles and a minimum value on the edges. A transversal cost between adjacent locations in the area from the position of the vehicle and toward a destination is calculated in which the transversal cost increases proportionately with the value of the field. A route is then planned from the position of the vehicle to the destination which minimizes the transversal cost. | 04-23-2009 |
| 20090306881 | DETECTING PRINCIPAL DIRECTIONS OF UNKNOWN ENVIRONMENTS - Apparatus and methods according to some embodiments of the present invention use a graphical model, such as a Markov random field model, to represent principal driving directions within an environment. The model has a plurality of nodes representing spatial locations within the environment, and the principal direction for each node is determined probabilistically using linear features detected within an image of the environment. Apparatus and methods according to embodiments of the present invention can be used in improved autonomous navigation systems, such as robotic vehicles. | 12-10-2009 |
| 20100034422 | OBJECT TRACKING USING LINEAR FEATURES - A method of tracking objects within an environment comprises acquiring sensor data related to the environment, identifying linear features within the sensor data, and determining a set of tracked linear features using the linear features identified within the sensor data and a previous set of tracked linear features, the set of tracked linear features being used to track objects within the environment. | 02-11-2010 |
| 20100274430 | DETECTION OF TOPOLOGICAL STRUCTURE FROM SENSOR DATA WITH APPLICATION TO AUTONOMOUS DRIVING IN SEMI-STRUCTURED ENVIRONMENTS - A method of creating an obstacle-free diagram using topological sensor data to form a graph corresponding to a driving path, transforming the graph using discrete heuristics, locally smoothing a plurality of edges of the graph after the transforming, and globally smoothing the graph after the locally smoothing. Transforming includes deleting an edge of the graph, merging two intersections of the graph into a single intersection, and collapsing a plurality of edges forming a loop into a single edge. Locally smoothing includes smoothing a lane segment of the graph by minimizing a sum of a function of smoothness and a function of distance. Globally smoothing includes defining an intersection potential and minimizing a sum of the function of smoothness, the function of distance, a function of intersections and a function of direction. | 10-28-2010 |
| 20100299013 | USING TOPOLOGICAL STRUCTURE FOR PATH PLANNING IN SEMI-STRUCTURED ENVIRONMENTS - A method of creating a lane network of a semi-structured environment for a vehicle, assigning a corresponding cost function to each of a plurality of coordinates of the semi-structured environment using the lane network and a state of the vehicle, the state of the vehicle corresponding to a coordinate location of the vehicle and an angular orientation of the vehicle, and determining an obstacle-free path on the semi-structured environment using the cost function of each of the plurality of coordinates. | 11-25-2010 |

| 20110145219 | OBJECTIVE AND SUBJECTIVE RANKING OF COMMENTS - A system may receive a request for comments associated with a particular document, identify a comment associated with the particular document, generate an objective score for the comment that is independent of a user associated with the request, identify the user associated with the request, generate a subjective score for the comment based on parameters associated with the identified user, generate a combined score for the comment by combining the objective score and the subjective score, and provide the comment, ranked based on the combined score, to the user for presentation with the particular document. | 06-16-2011 |
| 20110161413 | USER INTERFACE FOR WEB COMMENTS - One or more server devices receive a request associated with a link, where the link is further associated with a comment and where the comment provides an opinion of, or remarks upon, a content of a document. The one or more server devices retrieve a content of the comment associated with the link from a database and retrieve the document. The one or more server devices generate another document that displays the content of the comment and includes a frame that further displays the document, and send the generated another document to the client device. | 06-30-2011 |
