Programmable differential delay circuit with fine delay adjustment
Granted: November 28, 2002
Application Number:
20020175728
Circuitry that provides additional delay to early arriving signals such that all data signals arrive at a receiving latch with same path delay. The delay of a forwarded clock reference is also controlled such that the capturing clock edge will be optimally positioned near quadrature (depending on latch setup/hold requirements). The circuitry continuously adapts to data and clock path delay changes and digital filtering of phase measurements reduce errors brought on by jittering data…

Multiple light source color balancing system within a liquid crystal flat panel display
Granted: November 7, 2002
Application Number:
20020163529
A system for color balancing within a liquid crystal flat panel display unit. The present invention includes a method and system for altering the brightness of two or more light sources, having differing color temperatures, thereby providing color balancing of a liquid crystal display (LCD) unit within a given color temperature range. The embodiments operate for both edge and backlighting systems. In an embodiment, two planar light pipes are positioned, a first over a second, with an air…
System, method, and computer program product for capturing a visualization session
Granted: May 30, 2002
Application Number:
20020063715
A system and method are provided for automatically capturing a graphics session so that the session can be subsequently re-created in a precise manner. In some embodiments, the image data produced by the rendering process is recorded and stored in a memory medium. The image data can then be used to re-create the images produced by the original rendering process. The image data can be collected through a connection at the graphics processing host, at the client computer from which the…
Method and apparatus for handling invalidation requests to processors not present in a computer system
Granted: May 16, 2002
Application Number:
20020059500
A node controller (12) in a computer system (10) includes a processor interface unit (24), a memory directory interface unit (22), and a local block unit (28). In response to a memory location in a memory (17) associated with the memory directory interface unit (22) being altered, the processor interface unit (24) generates an invalidation request for transfer to the memory directory interface unit (22). The memory directory interface unit (22) provides the invalidation request and…
Method and system for presenting three-dimensional computer graphics images using multiple graphics processing units
Granted: February 7, 2002
Application Number:
20020015055
The present invention provides a method and system for presenting three-dimensional computer graphics images using multiple graphics processing units. The dimensions of the scene to be rendered are bounded by a rectangular volume decomposed into rectangular subvolumes. Vertices of graphics primitives are compared with subvolume boundaries to determine to which subvolume a graphics primitive should be assigned. A GPU is assigned to each subvolume to render the graphics data that lies…
Backshell assembly
Granted: January 3, 2002
Application Number:
20020001989
A cable connector backshell assembly for high frequency applications requiring reduced electromagnetic emissions. Aspects include providing sufficient physical spacing and electrical isolation between the signal conductors and the housing to meet EMI standards for HIPPI-6400 connector assemblies. One embodiment includes spring preloading of the electrical connecter. One embodiment includes a longitudinally floating connector.
