  • Publication number: 20200044989
    Abstract: An apparatus and method for queuing data to a memory buffer. The method includes selecting a queue from a plurality of queues; receiving a token of data from the selected queue and requesting, by a queue module, addresses and pointers from a buffer manager for addresses allocated by the buffer manager for storing the token of data. Subsequently, a memory list is accessed by the buffer manager and addresses and pointers are generated to allocated addresses in the memory list which comprises a plurality of linked memory lists for additional address allocation. The method further includes writing into the accessed memory list the pointers for the allocated address where the pointers link together allocated addresses; and migrating to other memory lists for additional address allocations upon receipt of subsequent tokens of data from the queue; and generating additional pointers linking together the allocated addresses in the other memory lists.

  • Patent number: 6718334
    Abstract: An improved document and image management system (“DIM system”) is provided for use by a digital computer in combination with a video display or other suitable output means to provide an system that operates, preferably, under the Microsoft Windows® shell environment and which, further, is cross-platform capable and application independent. With respect to the data, document, or image to be managed, the invention operates independently of both the computer platform and the application software therein operating that was used to create the data, document, or image. The programming method of the present invention obtains the indices needed to create an image from the application running on the Windows® desktop; and, thereafter, electronically files, or otherwise processes, the image. Such functionality is provided by targeting a data stream that is refreshing the graphical user interface (“GUI”) of a screen running on the Windows® desktop.

  • Patent number: 6299819
    Abstract: A double chamber vacuum resin transfer molding process is provided comprising the initial step of providing a double chamber vacuum resin transfer molding apparatus comprising a first mold portion and a second mold portion. The first mold portion and the second mold portion are configured such that, in an engaged state, the first mold portion and the second mold portion define a mold cavity and a brim cavity. The mold cavity is isolated from the brim cavity by a compressible seal. Either or both of the first mold portion and the second mold portion are further configured to define an injection gate in communication with the mold cavity, a mold cavity vacuum port in communication with the mold cavity, and a brim cavity vacuum port in communication with the brim cavity. The first mold portion, the second mold portion, and the compressible seal are arranged such that a decrease in brim cavity pressure below atmospheric pressure causes a corresponding decrease in mold cavity volume.
