Title: The Innovative Contributions of Anthony E Lifur
Introduction
Anthony E Lifur is a notable inventor based in Ridgecrest, California. He has made significant contributions to the field of magnetic sensing technology. His work is particularly recognized for its innovative approach to triaxial magnetic heading sensing apparatus.
Latest Patents
Lifur holds a patent for a "Triaxial magnetic heading sensing apparatus having magnetaresistors." This invention includes nulling coils and netoresistive sensors that have inputs and outputs. The nulling coils are arranged in parallel relation to three orthogonal planes intersecting at a common center point. The sensors are disposed along orthogonal axes in parallel relation to the orthogonal planes and in close proximity to the center point. Each sensor has a bridge configuration balanced in the absence of an applied external magnetic field and unbalanced in its presence. Additionally, a signal generator is connected to the inputs of the sensors for exciting them with a bipolar voltage waveform. This waveform exhibits alternating positive and negative voltage polarities punctuated by 'off' states of zero volts. Furthermore, a voltage integrator and low pass filter are connected in series with the output of each sensor to generate an error signal. This signal represents an imbalance due to the presence of an applied external magnetic field and couples the input and output of each nulling coil and sensor into a servo control loop. Each sensor is driven by the error signal to a magnetic nulling condition with zero steady state error. A pick-off resistor is connected to the output of the low pass filter to output a representation of the nulling current, providing a measure of the applied external magnetic field.
