Patent number: 8300244Abstract: Systems and methods for automatic discovery of a networked raster image process (RIP) engine are described. In one aspect, a device determines that an entity is searching for one or more RIP engines. Responsive to such determining, the device notifies the entity of its RIP engine status.Type: GrantFiled: April 16, 2003Date of Patent: October 30, 2012Assignee: Hewlett-Packard Development Company, L.P.Inventor: Robert Douglas Christiansen

Patent number: 8264715Abstract: An approach is provided for implementing locked printing on a printing device with remote unlock. The printing device includes a locked print process that is configured to examine print data received by the printing device and determine whether locked printing is to be used for the print data. Print data designated for locked printing is stored on the printing device. The printing device also includes a Web application configured to generate Web pages that define a Web-based graphical user interface. When processed at a client device, the Web pages allow a user to enter authorization data that is transmitted to the Web application on the printing device. The locked print process verifies the authorization data and if the authorization data is successfully verified, allows the user access to locked print data on the printing device. The approach may also be implemented using a common repository to store print data.Type: GrantFiled: April 25, 2006Date of Patent: September 11, 2012Assignee: Ricoh Company, Ltd.Inventor: Jayasimha Nuggehalli

Patent number: 7787156Abstract: A facsimile device connected to a public line in parallel with an external telephone is provided. The facsimile device includes a facsimile circuit configured to send and receive image data through the public line, a voltage detector that detects a voltage of the public line, a telephone status monitoring unit configured to judge whether the external telephone closes the public line based on the voltage of the public line detected by the voltage detector and a reference voltage, a monitoring operation control unit configured to keep the telephone status monitoring unit in an inactive state until a predetermined time elapses from a time when the facsimile circuit releases the public line, and to activate the telephone status monitoring unit if the predetermined time elapses from the time when the facsimile circuit releases the public line.Type: GrantFiled: March 27, 2006Date of Patent: August 31, 2010Assignee: Brother Kogyo Kabushiki KaishaInventor: Tomohiro Ito

Patent number: 7738722Abstract: Reduction in the blockiness of a simulated film grain block can be achieved either by the use of adaptive downscaling or adaptive deblocking filtering to adjust the intensity of the pixels at the block edge in accordance with at least one film grain block parameter, such as film grain size, intensity and texture. Performing such adaptive downscaling or adaptive deblocking filtering achieves improved performance at lower computational cost by avoiding modification of film grain block pixels in lesser affected areas.Type: GrantFiled: October 17, 2005Date of Patent: June 15, 2010Assignee: Thomson LicensingInventors: Cristina Gomila, Joan Lllach, Jeffrey Allen Cooper

Patent number: 6583887Abstract: Compression apparatus is described that operates to select an optimum compression procedure to apply to received image data. The compression apparatus can be employed in a page printer having a print engine that must be provided with video data at a constant rate in order to avoid a print underrun. The page printer operates to receive print data and to convert the received print data into rasterized page strips. Some or all of these rasteized page strips can then be compressed by the compression apparatus for later conversion to video data. The compression apparatus operates to compress each received rasterized page strip by selecting a compression procedure that results in a compressed strip that will provide optimum print quality while not causing a print underrun and that is below a threshold data size.Type: GrantFiled: February 26, 1999Date of Patent: June 24, 2003Assignee: Hewlett-Packard Development Company, L.P.Inventors: Scott Clouthier, Richard Benear, Gregory S. Saathoff, Jeffery M. Roberts
