Title: Berthold Wocher: Innovator in Capacitive Sensor Technology

Introduction

Berthold Wocher is a notable inventor based in Leonberg, Germany. He has made significant contributions to the field of capacitive sensor technology, holding a total of eight patents. His work focuses on innovative solutions for measuring fuel wall films and positional sensing in various applications.

Latest Patents

One of Wocher's latest patents is a capacitive sensor designed for the measurement of a fuel wall film, particularly in internal combustion engines. This sensor comprises multiple individual condenser elements, each featuring a first circular electrode and a second surrounding ring-shaped electrode mounted on a nonconducting support. A common conductor connects to each first electrode, allowing for separate signal detection from each condenser element. To enhance sensitivity and minimize interference, a third additional electrode is positioned on the opposite side of the support, acting as a shield against unwanted couplings.

Another significant invention is a capacitive position sensor that includes a capacitor arrangement made up of a stator and a rotor. The stator supports at least three coplanar electrodes shaped like circle sectors, while the rotor has a counterelectrode. An oscillator applies alternating current voltages to two of the stator electrodes, and the induced voltage on the counterelectrode is neutralized until it reaches zero. This process allows for precise measurement of the angular position of the rotor.
