Patent number: 9167215Abstract: In a machine vision system editing environment for a part program, a continuous stream of image acquisition operations are performed during a run mode. Previously, a continuous stream of image acquisition operations was achieved by utilizing different programming representations and syntax for programming and grouping image acquisition operations together in the part program. A new common syntax and representations are utilized wherein such continuous image acquisition operations are recorded in the same way as regular operations, with the running of the part program being performed in two stages. First, the portion of the part program that is to have the continuous stream of image acquisition is scanned for image acquisition operations, and the most efficient order for acquiring the images is determined. Second, while the image acquisition process is being performed, the portion of the part program is scanned again, with the image analysis operations then being performed.Type: GrantFiled: June 17, 2014Date of Patent: October 20, 2015Assignee: Mitutoyo CorporationInventors: Mark Delaney, Barry E.

Patent number: 9113196Abstract: A method and apparatus for processing a video signal using inter-viewpoint prediction are disclosed. The video signal processing method includes acquiring a type of a current block, acquiring a depth inter-view prediction flag according to the current block type, acquiring color information of a reference block corresponding to the current block when the current block is encoded using depth inter-view prediction according to the depth inter-view prediction flag, and predicting color information of the current block using the color information of the reference block. The video signal processing method performs inter-viewpoint prediction using depth information, such that a motion vector of a macroblock can be induced from a decoder using such depth information. Therefore, a motion vector of the macroblock is not separately coded. In addition, the video signal processing method uses a flag that indicates whether to perform inter-viewpoint prediction using depth information.Type: GrantFiled: November 10, 2009Date of Patent: August 18, 2015Assignee: LG Electronics Inc.Inventors: Jae Won Sung, Byeong Moon Jeon, Yong Joon Jeon

Patent number: 8957960Abstract: A machine vision system program editing environment includes near real time context generation. Rather than requiring execution of all preceding instructions of a part program in order to generate a realistic context for subsequent edits, surrogate data operations using previously saved data replace execution of certain sets of instructions. The surrogate data may be saved during the actual execution of operations that are recorded in a part program. An edit mode of execution substitutes that data as a surrogate for executing the operations that would otherwise generate that data. Significant time savings may be achieved for context generation, such that editing occurs within an operating context which may be repeatedly refreshed for accuracy in near real time. This supports convenient program modification by relatively unskilled users, using the native user interface of the machine vision system, rather than difficult to use text-based or graphical object-based editing environments.Type: GrantFiled: November 15, 2011Date of Patent: February 17, 2015Assignee: Mitutoyo CorporationInventors: Barry Saylor, Dahai Yu, Ryan Northrup, Gyokubu Cho, Akira Takada

Patent number: 8855189Abstract: Both live and offline transcoding of media is managed for storage in a cache. Requests for media are made by a client on a network and media taken from the cache and transcoded for delivery to the client. Media is also transcoded and stored in memory during idle request in anticipation of future requests during idle transcoder time between client requests. A prioritizer manages at least offline transcoding requests. A high priority queue operates at a higher priority than the low priority queue. The high priority queue receives live transcoding requests from a client on the network. A low priority queue receives offline transcoding requests. A media transcoder primarily transcodes media in accordance with requests from the high priority queue for delivery to a client on the network and then secondarily transcodes media in accordance with requests from the low priority queue when the high priority queue is empty.Type: GrantFiled: April 12, 2011Date of Patent: October 7, 2014Assignee: UV Networks, Inc.Inventors: Edward A Krause, Peter A Monta
