The first sheet stacker has a bottom and a lift. The sheet feeder includes an opening and a feed roller. The sheet conveyance device includes an assist plate supported to be movable between a first and a second position and an urging member. With the first sheet stacker mounted in an apparatus body, the assist plate moves from the first to the second position against the urging force of the urging member to allow passage of a sheet from the first sheet stacker to the sheet feeder. With the first sheet stacker removed from the apparatus body, the assist plate is urged by the urging member to move from the second to the first position to support the sheet conveyed from the second sheet stacker to the sheet feeder.Type: GrantFiled: March 1, 2023Date of Patent: December 12, 2023Assignee: KYOCERA DOCUMENT SOLUTIONS INC.Inventors: Hoang Viet Nguyen, Ha Thi Ngoc Do

Patent number: 8649592Abstract: A system for background image subtraction includes a computing device coupled with a 3D video camera, a processor of the device programmed to receive a video feed from the camera containing images of one or more subject that include depth information. The processor, for an image: segments pixels and corresponding depth information into three different regions including foreground (FG), background (BG), and unclear (UC); categorizes UC pixels as FG or BG using a function that considers the color and background history (BGH) information associated with the UC pixels and the color and BGH information associated with pixels near the UC pixels; examines the pixels marked as FG and applies temporal and spatial filters to smooth boundaries of the FG regions; constructs a new image by overlaying the FG regions on top of a new background; displays a video feed of the new image in a display device; and continually maintains the BGH.Type: GrantFiled: August 30, 2010Date of Patent: February 11, 2014Assignee: University of Illinois at Urbana-ChampaignInventors: Quang Huu Nguyen, Minh Ngoc Do, Sanjay Jeram Patel, Daniel Palmer Dabbelt, Dennis Jinn Lin

Patent number: 8643701Abstract: A system is disclosed for executing depth image-based rendering of a 3D image by a computer having a processor and that is coupled with one or more color cameras and at least one depth camera. The color cameras and the depth camera are positionable at different arbitrary locations relative to a scene to be rendered. In some examples, the depth camera is a low resolution camera and the color cameras are high resolution. The processor is programmed to propagate depth information from the depth camera to an image plane of each color camera to produce a propagated depth image at each respective color camera, to enhance the propagated depth image at each color camera with the color and propagated depth information thereof to produce corresponding enhanced depth images, and to render a complete, viewable image from one or more enhanced depth images from the color cameras. The processor may be a graphics processing unit.Type: GrantFiled: November 17, 2010Date of Patent: February 4, 2014Assignee: University of Illinois at Urbana-ChampaignInventors: Quang Huu Nguyen, Minh Ngoc Do, Sanjay Jeram Patel

Patent number: 8507009Abstract: This invention relates to novel colonic purgative compositions in a solid dosage form, comprising at least one purgative and at least one soluble, or soluble, nonfermentable binder, such as polyethylene glycol. Further, this invention relates to methods of using the colonic purgative compositions. The present compositions and methods are designed to improve patient tolerance and compliance, while at the same time improving the quality of bowel cleansing. The formulations and methods of this invention are particularly useful to cleanse the bowel prior to diagnostic and surgical procedures and can also be employed in lower dosages as a laxative to promote elimination and/or to relieve constipation.Type: GrantFiled: January 20, 2010Date of Patent: August 13, 2013Assignee: Salix Pharmaceuticals, Inc.Inventors: Stephen Skiendzielewski, Martin Rose, Ngoc Do
