Latest Patents
Highfill's latest patents include an "Active Control System and Amplifiers Including Damping Loops and Power Supplies with Over-Voltage Protection Pre-Regulators." This invention provides over-voltage protection circuits for power supplies, which limit input voltage spikes to power converters. The system incorporates damping loops that help dampen filter resonance, making it particularly advantageous for applications in aircraft and other vehicles where size and power consumption are critical. The over-voltage protection circuit senses AC and/or DC voltage levels above a detection threshold and momentarily disconnects the voltage input, reducing maximum voltage level input transients.
Another significant patent is the "Method, Apparatus and Controller for Machining Non-Circular Work Pieces." This invention involves a method and apparatus for machining non-circular work pieces using rotating equipment. The apparatus includes position sensors for deriving angular position signals, a flexible tool holder, and a solid-state vibration actuator that imparts active vibrational forces to the tool holder. This technology allows for precise control over the machining process, enabling the creation of non-circular work piece profiles with desired ovality.
