Title: Michael T. Murray: Innovator in Servosystem Technology

Introduction

Michael T. Murray is a notable inventor based in Rochester, NY (US). He has made significant contributions to the field of servosystem technology, particularly with his innovative approach to achieving high positional accuracy in movable members.

Latest Patents

Murray holds a patent for a "Constant velocity servosystem with high positional accuracy." This servosystem is designed to position a movable member, such as an optical head, over a rotating disk with constant velocity and high positional accuracy. The system utilizes a fast analog feedback loop controlled by a slower digital loop. The analog feedback loop locks the speed of the movable member to the speed of the rotating disk in a spiral recording track. The progress of the movable member is constantly monitored with the digital loop. A velocity error of known magnitude and direction is introduced into the system. When the error exceeds a preset limit, an error of the known magnitude but of the opposite direction is introduced. This innovative approach allows the servosystem to zig-zag about the desired position with small velocity changes, providing a substantially constant velocity system with high positional accuracy.
