Title: Innovations by Zachary Richards
Introduction
Zachary Richards is an accomplished inventor based in Epsom, NH (US). He has made significant contributions to the field of magnetic field sensing technology. With a total of 4 patents to his name, Richards continues to push the boundaries of innovation in his industry.
Latest Patents
Richards' latest patents include groundbreaking technologies such as high-resolution magnetic field sensors. One of his notable inventions is a method and apparatus for determining and transmitting speed and/or direction information for a rotating target using a magnetic field sensor. This invention generates a reference channel signal from at least one magnetic field sensing element and creates a virtual channel signal in quadrature with the reference channel signal. Additionally, a tangent signal is generated, and the slope of an arctangent of the tangent signal is determined, which corresponds to the rotational speed of the target. The speed and/or direction of the target can then be transmitted by a sensor integrated circuit (IC).
Another significant patent focuses on the regulation of coefficients used in magnetic field sensor virtual signal generation. This invention involves a magnetic field sensor that includes multiple sensing elements configured to generate at least two measured magnetic field signals. These signals are indicative of a magnetic field affected by an object and have a predetermined phase difference. A controller processes these signals to generate a virtual magnetic field signal, ensuring a desired phase difference between the reference and virtual magnetic field signals.
