Patent number: 10652414Abstract: According to an example, a scanner apparatus may include a housing, a scan panel positioned on the housing and a lid rotatably mounted to the housing. The lid may be moved between a closed position and an open position, in which in the closed position, the lid covers the scan panel and in the open position, the lid is extended away from the scan panel. The scanner apparatus may also include an optical sensor to detect media placed on the scan panel and a media engine to determine whether the optical sensor has detected a media on the scan panel while the lid is in the open position.Type: GrantFiled: September 12, 2016Date of Patent: May 12, 2020Assignee: Hewlett-Packard Development Company, L.P.Inventors: Gareth Ryan Kelly, Curtis J Behrend, Matthew Douglas Reier, Arthur H Barnes, Kevin Lo

Patent number: 8649073Abstract: A scanner assembly includes an automatic document feeder and a first scanner. The automatic document feeder defines a media pathway that includes an input portion and an output portion having an exit roller. The first scanner is positioned along the media pathway upstream from the exit roller. In a first assembled configuration, the assembly is configured to scan both a first side and a second side of the media via the first scanner. In a second assembled configuration, the assembly additionally includes a second scanner positioned along the output portion and interposed between the first scanner and the exit roller. In the second configuration, the assembly is configured to scan the first side of media via the first scanner and to scan the second side of media via the second scanner.Type: GrantFiled: June 10, 2011Date of Patent: February 11, 2014Assignee: Hewlett-Packard Development Company, L.P.Inventors: Thaddie Natalaray, Kyi Thu Maung, U Kyaw Thu Ra, Tok Wee Hien, Yeo Meng Hui, Lam Siew Hong, Jeoffrey Goh Choon Kiat, Thong Wei Leong, Chiam Ter Wei, Long C. Doan, Jeffrey C. Madsen, Curtis J. Behrend, James C Albritton-Mcdonald, Keng-Leong Ng

Patent number: 8613440Abstract: An automatic document feeding device including a pick motor coupled with a pick assembly, a deskew motor coupled with a deskew assembly, a sensor assembly coupled with a main media path and the deskew motor, and a feed motor coupled with a feed assembly. The deskew motor drives the deskew assembly, the deskew assembly deskewing the media sheet and moving the media sheet from the pick assembly to the feed assembly, the deskew assembly moving independently of the pick assembly and the feed assembly. The sensor assembly includes a plurality of sensors. The sensor assembly senses the media sheet moving along the main media path and sends at least one signal to a computer. The computer, based on the at least one signal, sends, an activation signal to at least one of the pick, deskew and feed motors and the first scanner.Type: GrantFiled: July 11, 2011Date of Patent: December 24, 2013Assignee: Hewlett-Packard Development Company, L.P.Inventors: Long C Doan, Thaddie Natalaray, Kyi Thu Maung, Jeffrey C Madsen, Jim Albritton-Mcdonald, Jeoffrey Goh, Hin Peng Teoh, Curtis J Behrend, Keng Leong Ng

Patent number: 7148901Abstract: A method for rendering an image for a staggered color graphics display comprises calculating first and second color values for each pixel or dot. The first color value is based on a portion of the image corresponding to a first dot, and the second color value is based on a portion of the image corresponding to at least one dot adjacent to the first dot. The method further includes calculating a rendered value from the first and second color values for display in the first dot.Type: GrantFiled: May 19, 2004Date of Patent: December 12, 2006Assignee: Hewlett-Packard Development Company, L.P.Inventors: Stephane G.

The conversion apparatus includes a normalization and clipping block to convert the YCaCb data generated from the inverse DCT operation. In addition, the conversion apparatus includes a color space conversion block that performs a color space conversion, using matrix multiplication, on the output of the normalization and clipping block.Type: ApplicationFiled: August 7, 2001Publication date: December 19, 2002Inventors: Harlan A. Talley, Phillip McCoog, Curtis J. Behrend

Patent number: 6144778Abstract: A computerized methodology for reducing swath scanner swath boundary discontinuities is provided by using a predetermined overlap of pixel rows during each sequential scan. Pixel data from a first scan of the overlapped pixel rows is compared to the pixel data from a second scan of the overlapped pixel rows, identical pixels of the overlapped pixel rows ideally having the same representative scan data. Errors are compensated by weighting representative scan data for each pixel row, linearly decreasing the weighting in proportion to the proximity to the swath boundary. In one embodiment, the weighting factor is an increase or decrease in the first scan data relative to the percent change in white level intensity captured in the second scan of the overlapped pixel rows.Type: GrantFiled: September 8, 1997Date of Patent: November 7, 2000Assignee: Hewlett-Packard CompanyInventors: Robert W. Beauchamp, Curtis J. Behrend

Underpulsed scanner with variable scan speed, P. W. M. color balance, scan modes and column reversal
Patent number: 5991055Abstract: Scan exposure in a row or swath scanner is controlled by pulsing light sources with pulses that are separated by dark intervals from each other--and from the detector readout periods. Detector sequencing is thereby made independent of the velocity of the pixel-line advance mechanism. Different pulse widths for different colors provide color correction without calculation, or regularize color-space conversion calculations where needed. In a swath scanner, known technology of printing modes is imported into the scanning context. Order of pixel columns within each swath is reversed for printing--permitting use of novel configurations such as a dual-parallel-flatbed copier in which a single common scan-and-advance mechanism simultaneously transports the scan sensor and printheads. To produce mirror images, this configuration is also used without column reversal. In addition to red, green and blue light sources, an infrared source is used for reading invisible indicia that identify forms or media types.Type: GrantFiled: September 23, 1996Date of Patent: November 23, 1999Assignee: Hewlett-Packard CompanyInventors: Robert D.
