Title: Erhard Schweninger: Innovator in Optical Sensor Technology

Introduction

Erhard Schweninger is a notable inventor based in Karlsruhe, Germany. He has made significant contributions to the field of optical sensor technology, holding a total of four patents. His work focuses on enhancing the functionality and efficiency of optical measuring arrangements.

Latest Patents

One of Schweninger's latest patents is for a compensation system for an optical sensor via a printed circuit board. This opto-electronic measuring arrangement is designed to be largely independent of extraneous light. It features emitted and compensation light sources that emit light in a time-sequential and phased manner, with the emitted light being phase-shifted by 180 degrees. An optical receiver captures the light emitted by the source and reflected by the object being measured, along with the light from the compensation source. The actuation signals for both light sources are controlled to minimize the synchronous signal difference in the receiver. The printed circuit board serves as the optical conductor between the compensation light source and the receiver diode.

Another significant patent is the interference-compensated sensor, which detects objects in a contactless manner, particularly useful as a rain sensor. This sensor includes two identical measuring channels, each with a control device and output. A main subtractor outputs the difference between the signals from the measuring channels. The controller unit connected to the main subtractor can adjust the measuring channels to ensure the output signal is controlled to zero, allowing for the detection of objects in the area.
