Title: The Innovations of Charles Herbert Hasenauer

Introduction

Charles Herbert Hasenauer is a notable inventor based in Rochester, NY (US). He has made significant contributions to the field of electrophotography, holding a total of 8 patents. His work has advanced the understanding and measurement of developer density in electrophotographic systems.

Latest Patents

Hasenauer's latest patents focus on the resonant-frequency measurement of electrophotographic developer density. In one of his inventions, developer density is measured in an electrophotographic system using first and second mutually-insulated electrodes. These electrodes define a working volume through which the developer passes without contacting the first electrode. An AC voltage or current source is connected to the electrodes, and the corresponding current or voltage across the electrodes is measured. A processor then automatically determines the density of the developer in the working volume based on the measured current or voltage and the applied bias. This innovative approach enhances the accuracy and efficiency of measuring developer density in electrophotographic systems.
