  • Patent number: 11157770
    Abstract: A method for removing extraneous information from a drawing of a device having one or more parts, the extraneous information including a lead line and a part number, the method including detecting a starting point of a lead line with respect to a bounding box of the part number and determining a general direction of the starting point with respect to the bounding box, wherein the starting point is set as a current point; performing linear regression analysis of dark pixels in an area covered by a mask centrally located at the current point to yield a linear regression line slope; determining a next point based on the slope and the general direction; and updating the current point with the next point and repeating the performing and determining steps until the lead line ends; and removing the lead line based on a path traced by the starting and current points.

  • Patent number: 10216993
    Abstract: A non-transitory computer readable medium storing a program causing a computer to execute a parsing process including extracting one or more figure descriptions from a first entity of document in a sequential order and calculating the number of figure descriptions from the first entity of the document having figure descriptions; extracting one or more drawing pages from a second entity of document in a sequential order and calculating the number of drawing pages from the second entity of the document having drawing pages; computing a varying list of figure descriptions; and combining the varying list of figure descriptions with one of the one or more drawing pages to produce the single output, whereby a user of the single output can readily identify a figure number of the one of the one or more drawing pages and associate the figure number with a description from the varying list of figure descriptions.

  • Patent number: 8184995
    Abstract: A diagnostic system made part of or for use with a document handling device in which a customer is guided toward performance of at least one comparison means in a diagnostic routine analysis. The comparison means is selected from a group comprising (1) a first comparison comparing a fused print media and an unfused print media for presence of a defect, (2) a second comparison comparing an output print media and at least one image on a screen for a type of defect, and (3) a third comparison comparing a low-charged print media and a no-charged print media for qualities of the defect. The customer enters a selection based on results of the first, the second, or the third comparisons. The diagnostic system can identify a part causing a defect in the print media based on results of the comparisons.

  • Patent number: 8081914
    Abstract: An apparatus (100) and method (200) that detaches media from a fuser in a printer is disclosed. The method can include feeding (220) a media sheet through a fuser member and applying (230) gas from an air knife to the media sheet on the fuser member to detach the media sheet at a detach point from the fuser member. The method can also include asserting (240) tension on the media sheet using a set of rotational members and continuing to apply gas from the air knife to the media sheet until the set of rotational members asserts tension on the media sheet.
