Title: Innovations of John R Ellison, Jr.

Introduction

John R Ellison, Jr. is a notable inventor based in Bethany, CT (US). He has made significant contributions to the field of optoelectronics, particularly in the development of sensors for measuring rotational positions. With a total of 2 patents to his name, Ellison's work showcases his expertise and innovative spirit.

Latest Patents

One of his latest patents is the Optoelectronic Rotational Position Sensor. This apparatus is designed to sense the rotational or angular position of a shaft. It incorporates two light transmission paths, each equipped with a separate photodetector that provides an electrical signal in response to the intensity of received light. The electrical signals from the photodetectors are differentially processed to obtain a signal representative of the rotational position. Devices are included in each of the light transmission paths to vary the intensity of light transmitted, and these devices are mechanically coupled to the shaft. This design ensures that the variations in the respective light paths are opposite. Consequently, the differentially processed photodetector signals are unaffected by the absolute position of the shaft and respond only to deviations from a reference position. Furthermore, this differentially processed signal exhibits a higher degree of linearity than was previously obtainable. Various embodiments are disclosed for achieving this opposite variation in the respective light paths. The angular position sensor is preferably utilized in a torque wrench or similar device for sensing applied torque.

Career Highlights

Ellison's career is marked by his innovative contributions to sensor technology. His work has been instrumental in enhancing the accuracy and reliability of rotational position sensing devices. He is associated with Eotec, a company that focuses on advanced technological solutions.
