Title: The Innovative Contributions of David G. Hoag

Introduction

David G. Hoag is a notable inventor based in Medway, Massachusetts. He has made significant contributions to the field of technology, holding three patents that showcase his innovative spirit and technical expertise. His work primarily focuses on advanced systems that enhance precision and functionality in various applications.

Latest Patents

One of Hoag's latest patents is a laser pointing system. This system directs a laser beam at one face of a steering mirror to produce a steered reflected beam. A highly attenuated portion of the laser beam passes through the mirror, leaving at a second side, which also reflects a stellar field. A star of the stellar field and the attenuated beam are both imaged on a star tracker. The mirror is moved so the two images coincide, thus aligning the steered beam parallel to the direction of the star. A gyro package detects changes in the system orientation to update the mirror reference position, and a processor provides command coordinates to move the beam from the stellar coordinates and cause it to point in a selected target direction.

Another significant patent is the electromagnetic isolator/actuator system. This system is designed for suspending a platform element with respect to a base element. It includes electromagnetic isolator/actuators, featuring a permanent magnet with a pole gap between the magnetic poles, and a coil made of electrically conductive material. The coil and permanent magnet are positioned so that at least a portion of each of the coil turns is within the pole gap of the permanent magnet, aligned substantially perpendicularly to the polar axis of the permanent magnet. When electric current is applied to the coil, an electromagnetic force is generated between the coil and the permanent magnet. This force is proportional to the current and is substantially independent of the relative velocity of motion between the coil and the magnet.
