Title: The Innovations of Robert E Johnson

Introduction

Robert E Johnson is a notable inventor based in Ballston Spa, NY (US). He has made significant contributions to the field of engineering, particularly in the development of advanced control circuits for magnetic bearings and counting devices. With a total of 2 patents to his name, Johnson's work exemplifies innovation and technical expertise.

Latest Patents

Johnson's latest patents include the "Velocity Observer" and "Imbalance Observer" circuits. These circuits are designed to control the journals in the magnetic field of an attractive type active magnetic bearing and/or damper. The unique aspect of these circuits is their use of integrators instead of differential components. The velocity observer circuit employs a position feedback loop and a velocity observer feedback loop, both with variable gain, to effectively control the levitation of the journal in the magnetic field. Meanwhile, the imbalance observer circuit recreates the journal acceleration directly from displacement measurements, which can be utilized both online and offline to suppress vibrations.

Another significant invention by Johnson is a high-speed counter for thin objects. This device counts objects arranged in a stacked relationship and includes a bifurcated optical cable, a light source for directing light through the stack, and a sensor that generates a signal proportional to the light reflected by the stack. The signal is then digitized and sent to a digital counter, with various displays connected to indicate the count results.
