  • Patent number: 5638004
    Abstract: A multiconductor continuity and intermittent fault analysis system that sects the cable to controlled environmental stress stimuli, such a vibration at controlled frequencies, during testing. Multiconductor cables used for the transmission of digital data and control signals include multiple individual conductors terminating at both ends in pins or sockets that are grouped together in a connector. Physical defects in these cables can be permanent, or they can be intermittent faults, such as temporary breaks or shorts caused by vibrational stress on the cables. By vibrating the cable under test and measuring continuity rapidly enough to detect short-term anomalies, even intermittent faults are located.
