Eberhard Ullrich

Title: Eberhard Ullrich: Innovator in Circuit Arrangement Technology

Introduction

Eberhard Ullrich is a notable inventor based in Konstanz, Germany. He has made significant contributions to the field of circuit arrangements, particularly in the area of white level acquisition for black and white imaging systems. His innovative approach has led to the development of a unique patent that enhances the functionality of photosensors.

Latest Patents

Ullrich holds a patent for a "Circuit arrangement for white level acquisition for the black/white." This circuit arrangement consists of a first adder that connects digitized output signals from photosensors and a second input linked to a white level memory. Additionally, it features a second adder that integrates the currently stored white level with a correction signal, which is then read back into the white level memory. A comparator follows the first adder, supplying either a black or white signal based on a threshold level derived from maximum and average blackening values. The correction signal, influenced by various factors, provides a white level increment or decrement for the white level memory, depending on the carry signal from the first adder.
