Patents by Inventor Larry E. Cunningham

Larry E. Cunningham 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).

  • Telemetry apparatus and method with digital to analog converter internally integrated within C.P.U.
    Patent number: 5227783
    Abstract: The disclosure relates to a microprocessor based telemetry apparatus and method utilizing a commercially available IBM PC-AT or compatible CPU. Three hardware cards fit in existing slots within the computer chassis. Software is provided to accomplish, in combination with the cards, what has essentially required a mainframe computer heretofore. The microcomputer is equipped with novel hardware and software to provide PCM bit synchronizer/decoder, decommutator, time code reader and digital-to-analog converter functions. Data is stored in real time using interleaved buffers, novel software and a hard disk. Data can be archived on digital tape. Data logging can be carried out at sustained rates approaching 2 million bits per second, up to six times faster than with MS-DOS yet files are accessible with MS-DOS. Real-time data scaling and display of up to 128 separate parameters are accomplished.
    Type: Grant
    Filed: May 10, 1991
    Date of Patent: July 13, 1993
    Assignee: The Regents of New Mexico State University
    Inventors: Harold L. Shaw, Randall B. Smith, Larry E. Cunningham, Barry E. Rishel, John P. Gioannini, Warren B. Harkey
