The graphics memory address is delivered to the graphics memory switch via a point-to-point, packet based interconnect. The graphics memory switch generates a physical system memory address and delivers the physical address to a root complex. The physical system memory address is delivered to the root complex via a point-to-point, packet based interconnect.Type: GrantFiled: December 24, 2003Date of Patent: August 12, 2008Assignee: Intel CorporationInventor: Sunil A. Kulkarni

Patent number: 7411593Abstract: A system, method and program product for rotating a first image in an image buffer such that the resulting, rotated image is substantially free of an aliasing error, i.e., broken lines, stair stepped edges, etc., is disclosed. An algorithm is applied to the first image that uses weighted sums of data points of the first image to create the rotated image. The weighting is based on the skew angle and data point location of the first image. The resulting rotated image also has a reduced data storage space requirement compared to rotated images created by prior art techniques.Type: GrantFiled: March 28, 2001Date of Patent: August 12, 2008Assignee: International Business Machines CorporationInventors: Ravi Prakash, Clair Frederick Rohe, Robert E.

Patent number: 7411595Abstract: Methods and products are disclosed concerning extraction of selected components of a warping of an image. Given a warped image and a distortion grid, the distortion at any point in the image may be viewed locally as a displacement and a linear transform. The linear transform can be manipulated to extract elements of the local distortion such as skew, rotation, magnification and combinations. The selected components may then be selectively applied at other locations of the same or a different image, using a variety of virtual paintbrushes for different effects.Type: GrantFiled: November 28, 2001Date of Patent: August 12, 2008Assignee: Adobe Systems IncorporatedInventor: Todor G. Georgiev

Patent number: 7411596Abstract: In a gradation voltage generation circuit used in a video signal line driving circuit for driving video signal lines of a liquid crystal display device by time division based on switching control signals, a first variable resistor circuit is connected between one terminal of a voltage divider circuit for generating a gradation voltage group and a power source line for supplying a high-level voltage, and a second variable resistor circuit is connected between the other terminal of the voltage divider circuit and a power source line for supplying a low-level voltage. The resistances of the variable resistor circuits are switched based on the switching control signal. Thus, in the periods in which the video signal lines respectively connected to R, G and B pixel formation portions are driven, gradation voltages that are adapted to the gradation reproducibility for R, G and B are outputted respectively.Type: GrantFiled: April 7, 2004Date of Patent: August 12, 2008Assignee: Sharp Kabushiki KaishaInventors: Ken Inada, Taketoshi Nakano, Toshihiro Yanagi

Patent number: 7411599Abstract: A mail processing apparatus has a field table and a printer disposed above the feed table for printing indicia on a mailpiece moved in a movement direction along the feed table. A start sensor detects a leading edge of the mailpiece and supplies a signal to a microprocessor controller that operates the printer, in order to initiate a printing event on the mailpiece. An ejection roller is disposed following the printer and is operated by a motor to eject the mailpiece from the printer. An end sensor is disposed near the ejection roller and detects a trailing edge of the mailpiece, and supplies a signal to the microprocessor controller that causes the microprocessor controller to disconnect the voltage from the motor that operates the ejection roller.Type: GrantFiled: September 21, 2005Date of Patent: August 12, 2008Assignee: Francotyp-Postalia GmbHInventors: Frank Geserich, Frank Reisinger
