Charles E. Shinn 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).

  • Method for detecting the start of data field in a recording medium by detecting the sequence of bit codes
    Patent number: 5268798
    Abstract: A memory system having a moving memory recording media. A sector in each track on the media includes recordings defining a synchronizing field and a start of data field. Selected bit signals of bit signals derived from the recordings are simultaneously combined in a plurality of differing bit signal combinations. The simultaneously validity of all of the bit signals in each of a predetermined number of the differing bit signal combinations, which predetermined number is less than the plurality of bit signal combinations, provides fault tolerant detection of the start of data field.
    Type: Grant
    Filed: February 24, 1993
    Date of Patent: December 7, 1993
    Assignee: Hewlett-Packard Company
    Inventor: Charles E. Shinn
  • Method and apparatus for detecting a start of data position in differing tracks
    Patent number: 5243471
    Abstract: A sector in each track of a moving memory recording media includes recordings defining a synchronizing field and a start of data field. Selected bit signals of bit signals derived from recordings are simultaneously combined in a plurality of differing bit signal combinations. The simultaneous existence or validity of all of the bit signals in each of a predetermined number of differing bit signal combinations, which predetermined number is less than the plurality of bit signal combinations, provides fault tolerant detection of start of data field.
