  • Publication number: 20050099434
    Abstract: Systems and methods for compositing an image directly from multiple source image data for reducing system memory footprint and bandwidth and for improving color quality of the image. The image is divided into spans, lines, and slices. Each line includes at least one span and each slice includes at least one line. All lines in a slice have spans associated with identical sources. An image is composited by reading the image data directly from one or more sources of each span. If necessary, the sources are blended. A control structure is used to provide the image context and identifies the sources of the spans. The control structure includes headers for each data stream from each source of each span. Also, the color quality of the image is improved by reducing the number of color space conversions that occur as the image is composited. All sources in the same color space are blended before being blended with sources from other color spaces. Preferably, no more than a single color conversion is required.

  • Publication number: 20050038935
    Abstract: Systems for servicing the data and memory requirements of system devices. A DMA engine that includes a data reservoir is provided that manages and arbitrates, the data requests from the system devices. An arbitration unit is provided that only allows eligible devices to make a data request in any given cycle to ensure that all devices will be serviced within a programmable time period. The data reservoir contains the data buffers for each channel of each device. A memory interface ensures that sufficient data for each channel is present in the data reservoir by making requests to a system's memory based on an analysis of each channel. Based on this analysis, a request is either made to the system's main memory, or the channel waits until it is evaluated again in the future. Each channel is thereby guaranteed a response time.

  • Patent number: 6824620
    Abstract: The invention is directed to a mehtod of cleaning an object in a controlled environment processing chamber into which solvents, water and/or gases are introduced. The process includes first applying a negative gauge pressure to the chamber to non-condensable gases and then introducing a solvent, solvent mixture, water or gas in either a liquid or vapor state to remove soluble contaminants from the surface of an object being processed in the chamber. Further steps recover residual solvent or solution from the object and chamber. A secondary cleaning step directs a vapor state fluid at high velocity at a solid surface of the object to remove insoluble material left behind after the pretreatment step. A final series of steps recovers any loose impediments or residual liquid or vapor from the chamber and returns the chamber to atmospheric pressure for removal of the cleaned object.

  • Patent number: 6802137
    Abstract: The present invention is directed to a controlled environment processing chamber of chambers in which parts are to be dried. The parts either contain water on or imbibed into the part. The process includes a means of applying a negative gauge pressure to the chamber to remove air or other non-condensable gases. Further, means are provided for introducing a solvent in a vapor state to the chamber to cause the water to flash off the part. A first system recovers water or aqueous solution(s) from the object being dried and the chamber. A second system, separate from the first system, further recovers residual solvent from the object and chamber after the drying process.

  • Patent number: 6783602
    Abstract: The present invention is directed to a method for controlled environment processing of parts in a chamber or chambers wherein solvents and/or solutions used for processing the parts can be introduced. The process includes applying a negative gauge pressure to the chamber to remove air or other non-condensable gases. Next a solvent, solvent mixture or solution in either a liquid or vapor state is introduced to the chamber. A first system is then applied to recover the solvent(s) or solution(s) from the object being processed and chamber, and a second system, separate from the first system, is applied that further recovers residual solvent or solution from the object and chamber. Treatment of the part may be in the form of coating, etching, deposition, cleaning, stripping, plating, adhesion, dissolving, penetrating, anodizing, impregnating, debinding or any other process in which material is removed or deposited on a solid surface by transfer from or to a liquid or gas phase.

  • Patent number: 6418942
    Abstract: An enclosed solvent and aqueous decompression processing system includes a chamber for holding an object to be processed. At least one vacuum pump applies a negative gauge pressure to the chamber to remove air and other non-condensable gases. Means are provided for introducing a solvent to the evacuated chamber to treat the object contained within. Treatment may be in the form of coating, etching, deposition, cleaning, stripping, plating, adhesion, dissolving, filtering or any other process in which material is removed or deposited on a solid surface by transfer from or to a liquid phase. A first system removes pressure from the chamber to produce vapor bubbles for processing. A second system increases pressure by ceasing to apply vacuum or adding non-condensable gases. The system includes recovery of the solvent from the chamber and object.

  • Patent number: 6033125
    Abstract: A multiposition optical connector 2 and a mating header 4 are disclosed. The connector includes a plurality of ferrules 10 for terminating individual plastic optical fiber cables 6. An alignment fixture 100 is used to precisely align each ferrule relative to the other ferrules and relative to peripheral mating surface protrusions 52 on a molded alignment plate 12. The ferrules are ultrasonically bonded to the alignment plate. True positioning for multiple fibers located in the multiposition connector relative to active optoelectronic devices 90 located in the header can be achieved when the connector and the header are mated. A previously assembled harness assembly using the optical connector 2 and a hybrid electrical and optical connector 202 is suited for use in making multiple connections to products, such as automobiles, in which the final assembly is completed in an assembly line.

  • Patent number: 5766026
    Abstract: An electrical connector assembly includes a first sealing subassembly having a shielded, fluid impermeable board (48) with a stake pin (44) for fastening the board to a housing (34). Electrical components (16) are fastened to the board, and include pedestals (51) which are in sealing engagement with respective seals (52). The seals provide sealing and spring biasing forces to the components (16), as respective top edges thereof are pressingly engaged by a hydraulic valve apparatus. Thus a fluid seal barrier is created for preventing the passage of fluid to the interior of the electrical connector assembly.
