Latest Patents
One of his latest patents is for a "Variable permeability magnetometer systems and methods for aerospace applications." This innovative magnetometer is designed to measure low field strength magnetic fields. It features a cylindrical coil assembly with a variable permeability core and terminals at both ends. The device includes a current source circuit that applies a voltage-controlled current across the terminals, and a voltage readout circuit that measures the voltage due to the applied current. The inductance of the coil assembly varies directly with the ambient magnetic field strength, allowing for accurate measurements of magnetic field strength.
Another significant patent is for an "Apparatus for measuring high frequency currents." This apparatus utilizes a non-ferrous core current probe coupled to a wide-band transimpedance amplifier. The current probe is designed with a secondary winding that has a winding resistance much smaller than the reactance of the winding. This design ensures that the sensitivity of the current probe remains flat over a wide range of frequencies, making it particularly useful for measuring human exposure to radio frequency currents.
