Title: George R. Simpson: Innovator in Document Scanning Technology

Introduction

George R. Simpson is a notable inventor based in Rochester, NY (US), recognized for his contributions to document scanning technology. With a total of 5 patents to his name, Simpson has made significant advancements in the field, particularly while working at Xerox Corporation.

Latest Patents

One of Simpson's latest inventions is the "Precession Scanning System." This innovative object scanning system utilizes a dual-rate mirror assembly to scan documents on a platen. The scanned image is then projected onto a photoreceptor through a corner mirror assembly. The design allows for the corner mirror assembly to be linearly translated during the scan cycle, which helps to reduce or eliminate the interdocument gap on the photoreceptor. This invention also optimizes the precession rate relative to scanning flyback time, enhancing efficiency in document scanning.

Another significant patent is the "Full Frame Flash Illumination System Utilizing a Diffuse Integrating." This illumination system is designed for document copying machines and features an optical cavity with interior walls coated in a white, diffusely reflecting material. The system includes a platen for positioning documents and a lens for forming images on a light-sensitive image plane. Illumination is provided by a single flash source within the cavity, which reflects multiple times off the walls to ensure uniform diffuse illumination of the document.
