Title: Shumin Cheng: Innovator in Electric Motor Technology and Imaging Systems
Introduction
Shumin Cheng is a notable inventor based in Vernon Hills, IL (US). He has made significant contributions to the fields of electric motor technology and imaging systems. With a total of 2 patents, Cheng's work reflects his innovative spirit and technical expertise.
Latest Patents
One of Cheng's latest patents is an electric motor with a retractable shaft. This electric motor is designed to control the lateral displacement of a shaft connected to a rotor. It includes one or more stator conductors that carry current and one or more permanent magnets to produce a magnetic field. When power is applied, the stator conductors interact with the magnetic field to generate a force with both axial and circumferential components. The shaft travels along the rotor axis in an axial direction when power is applied, and it retracts under the action of a biasing force when power is removed.
Another significant patent is a spectrum verification imaging system and method. This system determines whether a sample object has a color within a predetermined range. It includes a light source capable of projecting lights with different light wavelength spectra upon the sample object. A controller manages the light source to project various light wavelengths sequentially. While each light is projected, a monochromatic image capture device captures images with luminous intensity information. This information is then compared to a statistical range derived from images of a reference object.
