Patent number: 7906840Abstract: A semiconductor integrated circuit package, a printed circuit board, a semiconductor apparatus, and a power supply wiring structure that allow attainment of stable power source and ground wiring without causing resonance even in a high-frequency bandwidth are provided. In an interior portion of the package, a power source wiring and a ground wiring constitute a pair wiring structure in which the power source wiring and the ground wiring are juxtaposed at a predetermined interval so as to establish electromagnetic coupling therebetween.

Patent number: 7907123Abstract: One exemplary method embodiment herein can run an operating system on a processor and executes one or more applications on the operating system (sometimes simultaneously) that causes different input requests to be dynamically displayed on a visual display. If more than one application is being executed at a time, only one currently selected application can be available for user input at a time. These input requests can dynamically change depending upon the current state of the currently selected application. The method controls the keys with the operating system to dynamically illuminate only valid keys that correspond to input requests of the currently selected application being currently displayed on the visual display.Type: GrantFiled: December 14, 2005Date of Patent: March 15, 2011Assignee: Xerox CorporationInventor: John M.

Patent number: 7907786Abstract: A method suited to the detection and correction of red-eyes includes assigning a probability to pixels of a digital image of the pixel being in a red-eye, the probability being a function of a color of the pixel. Optionally, generally circular regions in the image of contiguous pixels which satisfy at least one test for a red-eye are identified. The test may include determining a size or shape of the region or an extent of overlap with a region comprising pixels having at least a threshold probability of being in a red-eye. For each of a plurality of the pixels, such as simply those in identified regions, or for all pixels or a larger group of the pixels, a color correction for the pixel is determined. The correction is a function of the assigned probability that the pixel is within a red-eye and a color of the pixel.Type: GrantFiled: June 6, 2005Date of Patent: March 15, 2011Assignee: Xerox CorporationInventors: Lixin Fan, Jutta K.
