  • Publication number: 20080079178
    Abstract: Parts to be chemically treated are processed in a controlled-environment processing chamber. The process includes applying a negative gauge pressure to the chamber to remove air or other non-condensable gases. The process includes introducing an oxygen free solvent or aqueous solution in a vapor or liquid state. A first system removes oxygen and volatile contaminants from the object being processed and chamber, and a second system further recovers residual solvent from the object and chamber. Eliminating oxygen from the process prevents deflagration within the system thus allowing for the use of flammable solvents within the process.

  • Publication number: 20070107748
    Abstract: An enhanced Vacuum Cavitational Streaming (VCS) process focuses on the formation of vapor bubbles and the transfer of a chemical from the solvent to the surface of the object while the chemical is in the vapor state within the bubble, i.e. a chemical mechanism. There is less importance on the rapid implosion (physical mechanism) of the bubble, and more focus on the controlled formation and collapse (as opposed to implosion) of the vapor bubble.

  • Publication number: 20060265738
    Abstract: Systems and methods for providing resource management in a distributed network are disclosed. A loose collection of devices in a network may not be aware of the power restrictions for other devices. Wall powered devices will generally have drastically different power settings than battery powered mobile devices. The invention provides a federation policy for time that can be used to slave to a local service responsible for understanding the local resource requirements of each device (or node) on the network. In such a distributed time system, all services in a particular time domain may be sped up, slowed down, or completely halted.

  • Publication number: 20060129736
    Abstract: A radio module that detachably connects with a host device. A radio module is provided that includes an antenna as an integral part of the radio module. The antenna satisfies regulatory requirements by being an integral part of the radio module. The radio module includes an interface circuit that provides the processing required for communication over a wireless network. The functionality of the interface can be divided between the radio module and the host device. The physical interface between a host device and the radio module may depend on which functions are implemented by the radio module and which functions are implemented by the host device. In one example, the physical interface is a standard connection that permits the radio module to be detachably connected with multiple devices. The radio module also includes a flexible cable such that the radio module can be optimally positioned within the wireless network.

  • Publication number: 20060007961
    Abstract: Real-time communication of multimedia data over heterogeneous networks that may include constant delay networks, variable delay networks that have a common reckoning of time, and variable delay networks that do not have a common reckoning of time. If there are any variable delay networks in which there is no common reckoning of time in the heterogeneous networks, a common reckoning of time is established in each of those networks. Then, a constant delay network is emulated for each variable delay network using the specific common time reckoning present in each variable delay network.

  • Publication number: 20050243789
    Abstract: Methods and systems for preventing unacceptable communication requests from being transmitted to a network-accessible service are disclosed. A domain name server for a local network including a network-accessible service returns an address for a network security system remote from the local network in response to a request for the address of the network-accessible service. The network security system processes communication requests directed to the network-accessible service to determine whether the communication request is a network intrusion attempt. If so, the network security system performs a network intrusion prevention technique, such as discarding the communication request, generating an alert or message or storing at least a portion of the communication request. Otherwise, the network security system forwards the communication request to the network-accessible service.

  • Publication number: 20050204074
    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.

  • Publication number: 20050146538
    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.

  • 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.
