Latest Patents

Hilliard's latest patents include a "Method and apparatus for measuring inductance." This invention provides a method for measuring changes induced in an inductive field on a wire-loop of an oscillator circuit. It operates based on variations in a current function without the need to measure frequency changes. The invention addresses the independent effects of induced noise on both the current and voltage functions of an inductance measurement circuit. By inductively coupling one input and directly coupling the second input of a comparator circuit, the phase of the current function can be adjusted to align with the phase of the voltage function. This combination results in an output that isolates the induced noise from the measured inductance. Another significant patent is the "Method and apparatus for active isolation in inductive loop detectors." This invention features an oscillator circuit designed for use with a wire-loop inductive sensor. It effectively attenuates common-mode noise and filters differential noise from ambient and crosstalk sources through active isolation.
