Latest Patents

One of Michael G Smith's key inventions is the "Magnetically damped azimuth resolver." This patent describes a method for damping a low-friction azimuth resolver using an array of small magnets that act on a metallic pendulum attached to the resolver shaft. The magnetic field interacts with the pendulum's motion to induce a motional electromotive force and associated currents. These currents produce forces that oppose the motion, effectively acting as a non-contact damper on the resolver shaft. When the resolver shaft is stationary, no eddy currents are generated, and thus no damping force is present. However, when the shaft moves, the pendulum cuts through the magnetic flux lines, generating a drag force that is proportional to the angular speed of the shaft. The pendulum is typically constructed from diamagnetic materials, such as lead or copper, ensuring that the induced forces are solely a result of motion. The magnetic field is produced by a compact array of small, intense samarium-cobalt magnets, providing uniform damping throughout the full 360 degrees of resolver motion. This innovative device is designed as a modification to standard resolvers, allowing for applications in environments where tight clearances have previously posed challenges.
