  • Method and apparatus for diagnosing difficult to diagnose faults in a complex system
    Patent number: 7100084
    Abstract: A method and apparatus for determining the root cause of no trouble found events in a machine is disclosed. The actual faults occurring during a predetermined time interval prior to the no trouble found event are analyzed and correlated with the no trouble found events in an effort to identify those actual faults that have a high correlation with each no trouble found event. If a high correlation is not found, then the no trouble found event is analyzed off-line to determine the root cause.
    Type: Grant
    Filed: August 26, 2003
    Date of Patent: August 29, 2006
    Assignee: General Electric Company
    Inventors: C. Richard Unkle, Nicholas Edward Roddy
  • Diagnosis of faults in a complex system
    Patent number: 6795935

Generally, this data is collected and stored in separate databases. The present invention teaches combining the data so that an ordered analysis reflecting the timing of faults, repairs, and operational information can be carried out to determine the root causes of the faults.
