    摘要： The present invention utilizes the existing DME transponder system infrastructure to augment existing ground surveillance multilateration (MLAT) capabilities by providing additional measurements for determining the position of an aircraft equipped with a DME transponder. DME listeners receive DME interrogation signals and DME reply signals, determine TDOA between the DME transponder and each DME listener, and transmit data to a central computer that clusters TDOAs between the DME transponder and the DME listeners and computes the aircraft position using the clustered TDOAs. The DME-aided MLAT can be used as a backup surveillance system when GNSS-based systems are unavailable. The DME-aided MLAT can be integrated with SSR receive units (RUs) performing multilateration (MLAT) calculations.

    摘要： For networked client-server computer graphics systems, performance is improved by caching immediate mode graphics commands in the server host. Two types of immediate mode command packets are employed—a full-size packet type and a truncated packet type. The full-size packet type includes a cache code field, a table index field and a data field corresponding to the command. The truncated packet type includes only the cache code field and the table index field. For certain outgoing immediate mode commands, if it is determined on the client side that the command's data field has not previously been stored within the server host, then the client host sends a full-size packet type to the server host to indicate the command. The server host executes the command and stores the command's data field in its own memory for possible later use. But if it is determined on the client side that the command's data field has previously been stored within the server host, then the client host sends only a truncated packet type to the server host to indicate the command. In the latter case, the server host executes the command by recalling a previously-stored data field responsive to the table index supplied in the truncated packet.

    摘要： A graphical display system utilizes a plurality of display devices and a plurality of graphical acceleration units for rendering graphical data to the display devices. More specifically, each of the plurality of graphical acceleration units respectively interfaces a portion of graphical data defining an image to one of the display devices. Each of the display devices displays a portion of the image based on the graphical data rendered to it. To make the system more efficient and/or to improve image quality, at least one of the graphical acceleration units includes a plurality of graphical pipelines for rendering the graphical data to be displayed by the display device that is interfaced with the one graphical acceleration unit.
