Title: Walter Jerry Pohribnij: Patents for Wrist Strap Monitoring

Introduction

Walter Jerry Pohribnij is an inventor associated with Palatine, Illinois. His patent work focuses on electronic circuitry for monitoring and testing wrist straps used in static electrical discharge dissipation systems. He is associated with Northrop Grumman Systems Corporation and holds 2 patents.

Latest Patents

Pohribnij’s patents address the reliability and testing of circuitry incorporated into a tag attached to a user-worn wrist strap.

“Wrist strap integrity check circuitry” describes circuitry that monitors the electrical connection from the wearer through the wrist strap to ground. It includes a discharge resistor check circuit to assess the resistor’s accuracy, a skin resistance check circuit to monitor the strap’s connection to the user, and a ground fault detect circuit to monitor its connection to ground.

“Wrist strap test mode circuitry” also monitors the wrist strap’s electrical connection and adds functionality for testing the tag. Its components include an oscillator, a signal transmitter, and circuits for checking the discharge resistor, skin resistance, and ground connection. A testing circuit checks the oscillator’s frequency, monitors the transmitted signal’s spectrum, and tests the functionality and limits of the other circuits.

Career Highlights

Pohribnij’s disclosed inventions center on practical safeguards for wrist strap systems used to dissipate static electricity. The integrity-check circuitry monitors key electrical connections, while the test-mode circuitry provides a way to evaluate the tag’s operation and the performance of its monitoring functions.

Collaborations

Pohribnij is associated with Northrop Grumman Systems Corporation. His listed coworkers include Warren E. Guthrie and Michael J. Trainor.

Conclusion

Walter Jerry Pohribnij’s two patents focus on monitoring wrist strap connections and testing the circuitry that helps ensure reliable static electrical discharge dissipation.
