Patents by Inventor Robert C. Flagg

Robert C. Flagg has filed for patents to protect the following inventions. This listing includes patent applications that are pending as well as patents that have already been granted by the United States Patent and Trademark Office (USPTO).

  • Patent number: 5471564
    Abstract: A resource oriented host computer-printer system in which the host computer and printer share information and data processing duties. A system and method for analyzing the execution times for draw primitives allows the host computer to determine whether the printer will be able to render draw primitives in real-time. If the printer cannot render the draw primitives in real-time, the host computer may send the draw primitives to be pre-rendered by the printer. The rendering is accomplished in less than thirty seconds. The host computer can determine the execution times for the draw primitives and dynamically alter the timeout period accordingly. If the printer exceeds the determined execution time, the host computer generate a timeout error message. No false timeout error messages are generated by the host computer because the timeout period is related to the actual processing time required by the printer.

  • Patent number: 5471563
    Abstract: A resource oriented host computer-printer system in which the host computer and printer share information and data processing duties. A system and method for analyzing the execution times for draw primitives allows the host computer to determine whether the printer will be able to render draw primitives in real-time. A resource assembler calculates the cost of executing each draw primitive within a band to determine if the printer can render the draw primitive in real-time. If the band is too complex for the printer to render in real-time, the printer may pre-render the band or the host computer will render the band and transmit the bit-map of that band to the printer. The host computer makes a series of decisions as to the best form for transferring data from the host computer to the printer. If the printer cannot store the bit-map data file, the bit-map data file is compressed.
