Title: The Innovations of Nis-Friedrich Ewald
Introduction
Nis-Friedrich Ewald is a notable inventor based in Munich, Germany. He has made significant contributions to the field of engineering, particularly in the area of rail vehicle technology. His innovative approach has led to the development of a unique method for determining the diameter of rail vehicle wheels.
Latest Patents
Ewald holds a patent for a "Method and apparatus for determining the diameter of rail vehicle wheels." This invention calculates the diameter of railroad wheels by utilizing data obtained from two marker points on the tread surface of the wheel. By simultaneously sensing these marker points and considering the known fixed locations of the marker point generators and sensors, Ewald's method defines a chord line and a chord height. These measurements ultimately allow for the accurate determination of the wheel diameter. A computer performs the necessary calculations, providing outputs that can be used for display or for controlling tools such as a wheel truing machine. Ewald has 1 patent to his name.
