Title: Oliver Duane Johnson: Patents in Display and Document-Handling Technology

Introduction

Oliver Duane Johnson is an inventor associated with Austin, Texas, and International Business Machines Corporation. His two patents address practical engineering challenges in electronic displays and the handling of paper documents.

Latest Patents

Johnson’s patent, “Tuning fork oscillator driven light emitting diode display unit,” describes a display that uses oscillating lines of light sources, such as LEDs, to form alphanumeric characters. The design suspends a base from a support and uses display arms carrying the light sources, together with counterbalancing arms that move in the opposite direction. Pulsing the lights at selected points in the oscillation creates the displayed characters.

His patent, “Document transport and separating device,” concerns feeding, separating, and aligning sheets of paper. Opposing devices use tips that move elliptically through intermittent force and rotational movement. Differences in the tips’ friction, along with their positioning relative to the paper path, help separate and transport individual sheets while guiding them into alignment.

Career Highlights

Johnson’s documented patent work spans two distinct areas: moving-light display systems and mechanical document transport. Together, the inventions illustrate approaches to coordinating motion, timing, and contact forces to produce reliable operation. His patent portfolio includes 2 patents.

Collaborations

Johnson’s work is associated with International Business Machines Corporation, commonly known as IBM. Frederick Fenn Quist, Jr. is identified as a coworker.

Conclusion

Oliver Duane Johnson’s patents reflect inventive work on both electronic display technology and paper-handling mechanisms, combining controlled motion with carefully designed system components.
