  • Wrist strap integrity check circuitry
    Patent number: 6035260
    Abstract: Improved electronic circuitry incorporated into a tag attached to a user worn wrist strap of a static electrical discharge dissipation system. The electronic circuitry monitors the electrical connection of the wrist strap from the user to ground, and comprises a discharge resistor and a discharge resistor check circuit for monitoring the accuracy of the discharge resistor. The electronic circuitry further comprises a skin resistance check circuit for monitoring the electrical connection of the wrist strap to the user, and a ground fault detect circuit for monitoring the electrical connection of the wrist strap to ground.
    Type: Grant
    Filed: April 23, 1997
    Date of Patent: March 7, 2000
    Assignee: Northrop Grumman Corporation
    Inventors: Walter Jerry Pohribnij, Warren E. Guthrie
  • Wrist strap test mode circuitry
    Patent number: 5872455
    Abstract: Improved electronic circuitry incorporated into a tag attached to a user worn wrist strap of a static electrical discharge dissipation system. The electronic circuitry monitors the electrical connection of the wrist strap from the user to ground and tests the functionality of the tag. The electronic circuitry comprises an oscillator, a signal transmitter, a discharge resistor and a discharge resistor check circuit for monitoring the accuracy of the discharge resistor. The electronic circuitry also comprises a skin resistance check circuit for monitoring the electrical connection of the wrist strap to the user, and a ground fault detect circuit for monitoring the electrical connection of the wrist strap to ground.
