Title: Wolfgang Patzwaldt: Innovator in Eddy Current Technology

Introduction

Wolfgang Patzwaldt is a notable inventor based in Reutlingen, Germany. He has made significant contributions to the field of eddy current technology, holding 2 patents that showcase his innovative methods for signal evaluation and metal detection.

Latest Patents

One of his latest patents is a method for the operation and evaluation of signals from an eddy current probe. This method involves supplying a transmitting coil with alternating current that includes three frequency components. The receiving coil signal, corresponding to an alternating current voltage, is broken down into frequency components. Through phase-control rectification, projection signals are formed that correspond to either the real or imaginary part of the coil signal. By forming differential signals from at least two projection signals of the same type, a combination signal is created and evaluated. This method is particularly advantageous for detecting mines while suppressing disturbing ground signals.

Another significant patent is related to phase shift compensation for metal detection apparatus. This invention involves a wire loop reference transmitter that is coupled with the excitation and receiver windings of metal detection apparatus. The reference signal can be alternately opened and closed through a switch, allowing for effective separation from other signals. This innovation enhances the accuracy of metal detection by utilizing phase control demodulation techniques.
