Title: Andreas Gruhle: Innovator in Electric Motor Testing and Photodetection
Introduction
Andreas Gruhle is a notable inventor based in Ulm, Germany. He has made significant contributions to the fields of electric motor testing and photodetection. With a total of 4 patents to his name, Gruhle's work showcases his expertise and innovative spirit.
Latest Patents
One of Gruhle's latest patents is a process and device for testing electric motors, particularly fan motors, for functionality. This invention involves a device that receives electromagnetic alternating fields produced by an electric motor through an antenna. The received signals are then analyzed for signal components in the frequency range of the rotation value of electric motors or their harmonics via an analysis unit. Upon determining functionality, the results are indicated by an indicator unit.
Another significant patent is the SiGe photodetector with high efficiency. This photodetector operates in two wavelength ranges and consists of two detectors arranged one on top of the other. Detector A is formed by a Si Schottky diode, which absorbs light in a region of less than 0.9 micrometers. Detector B, made of an Si/SiGe pn-diode, absorbs longer-waved light in the range of 1 to 2 micrometers. To enhance efficiency, detector B is equipped with an integrated resonator and a Bragg reflector mounted on the absorbing layer.
