Patent number: 9250150Abstract: A turbocharger wheel balance-test jig including a base, a clamp mechanism, and an arm. The arm extends along an axis of rotation. The clamp mechanism includes an actuator actuatable between a locked position and an unlocked position, the locked position rigidly holding the arm with respect to the base. The clamp mechanism includes a stop configured to restrict rotation of the arm around the axis of rotation. In a method for acceptance testing an imbalance level of a turbocharger wheel, an imbalance level of the balance-test jig is measured, and subtracted from a plurality of measurements of a combined imbalance level of the turbocharger wheel balance-test jig and the turbocharger wheel. An estimated indicator of turbocharger wheel imbalance is then formed, and the turbocharger wheel is accepted or rejected based upon whether the estimated indicator of the turbocharger wheel imbalance is within an acceptable indicator range.Type: GrantFiled: December 23, 2014Date of Patent: February 2, 2016Assignee: HONEYWELL INTERNATIONAL INC.Inventors: Geoffrey Park, Dominique Armand, Francis N. Rivot, Gerard H. Dieudonne

Patent number: 8159505Abstract: An efficient method of compositing planes onto a target surface using a computing device with graphics processing capability is disclosed. The method includes partitioning the target surface, on which planes are composited, into partitions. Each one of the partitions contains connected pixels to be formed by compositing an identical subset of the planes to be composited. Each partition is associated with a corresponding subset of the planes. Each partition and its corresponding set of associated planes are then provided to a graphics processor for composition, using exemplary software components including an application programming interface, a library and device driver software. An image is formed on the target surface by compositing each partition. Using the disclosed method, a single pass through stages of the graphics pipeline for the graphics processor is sufficient to composite multiple planes to form an image on the target surface.Type: GrantFiled: October 1, 2008Date of Patent: April 17, 2012Assignee: ATI Technologies ULCInventors: Jeffrey Cheng, Kenneth Man, Daniel Wong, Catalin Beju, Geoffrey Park, Iouri Kiselev

Publication number: 20060045332Abstract: A method for chroma key masking is provided. The method includes adjusting a first parameter representing a size of a first ellipsoid in a color space, adjusting a second parameter representing a size of a second ellipsoid in the color space, and generating a mask value for a given pixel color based on the location of the given pixel color in the color space, relative to the first and second ellipsoids. The first ellipsoid is centered about a prescribed chroma key color and the second ellipsoid is also centered about the prescribed chroma key color. The second ellipsoid surrounds the first ellipsoid in the color space.Type: ApplicationFiled: October 25, 2005Publication date: March 2, 2006Applicant: Sonic Solutions, Inc.Inventor: Geoffrey Park

Patent number: 6995805Abstract: A method, in one exemplary embodiment, for automatically detecting scene changes within a digital video sequence including a succession of frames, including computing metrics, for each of a plurality of frames from a digital video sequence, the metric of a frame being a measure of distance between the frame and a given frame, identifying a candidate frame for which the metric of the candidate frame differs from the metric of the predecessor frame to the candidate frame, by at least a first threshold, determining whether the metrics of successive ones of each of a first plurality of frames, successively following the candidate frame, differ from one another by less than a second threshold, and further determining whether the metrics of each frame of a second plurality of frames, successively preceding the candidate frame, are larger than a third threshold. A system, of one exemplary embodiment, is also described and claimed.Type: GrantFiled: September 29, 2000Date of Patent: February 7, 2006Assignee: Sonic SolutionsInventor: Geoffrey Park

Patent number: 6389322Abstract: A method of remotely manufacturing a cover for an article, such as a piece of upholstered furniture includes the steps of: ascertaining dimensional data of the article, and relating the data to individual portions of the article, determining a group of physically inter-related templates associated with these individual portions. Each template is definable on a plane of co-oridinates and is derived from a series of mathematical functions evaluated using this data, and using each template to form a corresponding cover piece and joining the cover pieces to form the cover for the furniture article.Type: GrantFiled: October 6, 1998Date of Patent: May 14, 2002Assignee: Cameleon Loose Covers Pty Ltd.Inventors: Thomas Michael Park, Robert Geoffrey Park
