Title: The Innovations of John Bedford
Introduction
John Bedford is a notable inventor based in Gorebridge, GB. He has made significant contributions to the field of optical image scanning and discrimination circuit arrangements. With a total of three patents to his name, Bedford's work has had a considerable impact on optical technologies.
Latest Patents
One of Bedford's latest patents is titled "Correction for scan period variation in optical image scanners." This invention addresses the issue of variations in scan periods by measuring and storing the scan times at which optical events occur. It involves detecting an optical marker near the end of the scan, determining the difference between the scan time of its detection and a stored scan period, and providing a correction for each measured scan time. This innovation enhances the accuracy of optical image scanners.
Another significant patent is the "Discrimination circuit arrangements." This invention features a discrimination circuit that can differentiate between an input signal in the form of a pedestal and disturbance signals superimposed on it. The circuit includes an A-D converter to digitize a disturbance-free reference pedestal signal, a circulating shift register to store the digitized reference signal, and a comparator to produce an output based on differences due to disturbances. This technology is integral to optical surface inspection apparatuses.
