Title: Harold E. Andrews: Innovator in Precision Actuation Technology
Introduction
Harold E. Andrews is a notable inventor based in Simi Valley, California. He has made significant contributions to the field of precision actuation technology, holding a total of 5 patents. His work primarily focuses on mechanisms that enhance the performance of optical systems in guided vehicles.
Latest Patents
One of his latest inventions is a precision linear actuator designed for accurately controlling the positioning of a lens element in the optical system of guided vehicles, such as missiles. This actuator features a robust frame that is rigidly affixed to the missile structure, incorporating bearing supports and separated guide pockets. The design includes a lever that is fixed to the frame by bearings, allowing for slight rotational movement. An actuator mechanism, such as a voice coil or drive motor, drives the lever to achieve its rotational motion. The lens holder, which is coupled to the lever through a cantilever spring arrangement, enables linear movement of the lens holder with respect to the frame.
Another significant invention by Andrews is a lens focusing mechanism that includes a bracket for retaining a lens. This bracket has an eccentric bearing that effectively moves the lens along its optical axis. The movement is achieved smoothly and without lubrication, showcasing the innovative design of the mechanism.
