  • Electrostatic discharge detector
    Patent number: 5463379
    Abstract: A detector for detecting electrostatic discharge events in an electronic component, assembly or system and including a display element which produces an immediate indication on exposure to a change in voltage level, an electrostatic discharge sensor, and circuit means for connecting said sensor to said display element. In one embodiment, the detector and the board or other device to be monitored are mounted in a housing having a visual access window with the display element of the detector viewable through the access window and with the detector positioned at the electronic device being monitored.
    Type: Grant
    Filed: November 1, 1993
    Date of Patent: October 31, 1995
    Assignee: Minnesota Mining and Manufacturing Co.
