Title: James W McKelvy: Innovator in Magnetic Sensor Technology
Introduction
James W McKelvy is a notable inventor based in Huntsville, Alabama. He has made significant contributions to the field of magnetic sensors, holding a total of 2 patents. His work focuses on enhancing the performance and reliability of magnetic sensing technologies, particularly in challenging environments.
Latest Patents
One of McKelvy's latest patents is titled "Power line field interference rejection for magnetic sensors." This invention features a discriminator that consists of two major components: a nonlinear filter for low velocity rejection and inhibiting logic for high-level rejection of alternating current magnetic fields. The nonlinear filter effectively reduces the frequency characteristics of specific signals while simultaneously increasing the frequency of normal interfering signals. The inhibiting logic is designed to sense and reject significant time-dependent interference, allowing for improved signal recognition even in the presence of substantial interference.
Another significant patent by McKelvy is "Quasi-stabilization for line of sight guided missiles." This invention provides an open-loop reduction in gunner aiming error through a rate gyro feedback mechanism to the missile command electronics. By filtering out low-frequency movements from the feedback circuit, this technology enables the tracking of low-frequency crossing targets while eliminating higher frequency gunner jitter inputs.
