摘要： An internal combustion engine system includes a spark-ignited internal combustion engine powered by a gaseous fuel. The engine system also includes an air intake in air providing communication with the internal combustion engine. Further, the engine system includes an exhaust system in exhaust gas receiving communication with the internal combustion engine. The exhaust system includes a methane oxidation catalyst through which at least a portion of the exhaust gas flows and an exhaust gas recirculation line in exhaust gas providing communication with the air intake.

摘要： A system and method for multi-goal path planning of welding robots with automatic sequencing. Input parameters associated with a number of goal points are obtained. The robot is moved through the multiple goal points based on the obtained inputs. One or more allowed cyclic paths are identified based on the obtained inputs. Weights are assigned to pre-defined attributes for path segments for each of the allowed cyclic paths. A cumulative score based on the values and assigned weights of the pre-defined attributes is calculated. An optimal path for the movement of robot across the goal points is identified based on the cumulative score.

摘要： Described herein are techniques and components for displaying a text advertisement in an online video being viewed by a user. The advertisement is selected based on keywords associated with the online video or the user, and the selected advertisement is presented as an overlay on the rendered video over regions of frames determined to be less important in the video. To determine importance, every frame of the online video is divided into grids, and parameters of the visual data in each grid are analyzed. Based on the analysis of each grid, regions in successive frames are identified to display the selected advertisement.

摘要： A method for estimating a plurality of geometrical parameters defining the size of a weld gun that has particular application for automatically selecting a weld gun for a welding operation. The method includes iteratively estimating a plurality of geometric parameters based on part section curves corresponding to a direction of approach of the weld gun to weld point of the plurality of weld points. Thereafter, a set of valid weld gun sizes are calculated based on the estimated plurality of geometric parameters. Similarly all the valid weld gun sizes are calculated corresponding to each of the weld gun approach direction. Further, each set of the valid gun sizes are estimated for each of the weld point for the welding operation. Finally, a weld gun for performing the welding operation is selected based on the set of weld gun sizes corresponding to the welding operation.
