Title: Paul Ohodnicki: Innovator in Transformer Designs and Magnetic Field Sensing

Introduction

Paul Ohodnicki is a prominent inventor based in Pittsburgh, PA, known for his significant contributions to transformer designs and optical sensing technologies. With a total of 10 patents to his name, he has made remarkable advancements in the field of electromagnetic components.

Latest Patents

Ohodnicki's latest patents include innovative transformer designs that provide very high isolation while maintaining high coupling between the windings. One notable example describes an isolation transformer that features a first excitation coil wound around a first core and a second excitation coil wound around a second core. The second core is electrically separated from the first core by a high resistivity magnetic material or a non-conductive material. The design allows for the first and second cores to include corresponding core segments arranged in a trident or quindent geometry. This unique arrangement enables the core segments to align when the first excitation coil is inserted into a void of the second excitation coil. The mechanical separability of these isolation transformer designs results in safe, energized, plug operations.

Another significant patent focuses on the optical sensing of magnetic fields using magnetically sensitive materials. This invention outlines a method for measuring the magnetic field of an electromagnetic component. The process involves instrumenting portions of the electromagnetic component by placing an optical fiber in electromagnetic communication with it. After energizing the component, the optical fiber is interrogated using light and an optical detector. Changes in the magnetic field are determined based on the detected changes in the light received by the optical detector.
