Title: Ulrich Dumke: Innovator in Fuel Cell Technology
Introduction
Ulrich Dumke is a notable inventor based in Ruesselsheim, Germany. He has made significant contributions to the field of fuel cell technology, holding a total of four patents. His work focuses on diagnostic systems that enhance the performance and reliability of compressors.
Latest Patents
Dumke's latest patents include a fuel cell system that features a diagnostic technique for unbalanced compressors. This innovative system utilizes a displacement sensor to measure the rotor shaft's displacement during operation. The sensor's dynamic frequency signal is processed through a bandpass filter, which eliminates an eigen-frequency related to shaft elasticity and rotor dynamics. The filtered signal is then rectified to ensure it is positive and converted into a DC signal by a low pass filter. This DC signal is analyzed by a controller to determine if the compressor's balance is compromised.
Another significant patent by Dumke is a diagnostic system for unbalanced motor shafts in high-speed compressors. This system employs a similar methodology, utilizing a displacement sensor and a series of filters to assess the rotor shaft's balance. The controller's analysis helps identify potential issues, ensuring optimal compressor performance.
