Title: Edward P. Coleman: Innovator in Scanning Technology
Introduction
Edward P. Coleman is a notable inventor based in Liverpool, NY (US). He has made significant contributions to the field of scanning technology, holding 2 patents that showcase his innovative approach to engineering challenges.
Latest Patents
Coleman's latest patents include a resonant motor driver system for data reading. This invention involves a method for driving a resonant electromagnetically-actuated motor, which is particularly useful for scanning light sources in data reading applications. The system applies drive current when the back-EMF induced in the actuator coil is zero and has a specific slope. The drive current is then removed after the induced back-EMF voltage has changed by a predetermined constant value. This design ensures that the motor operates across a scan angle that remains substantially constant, regardless of variations in ambient temperature, motor orientation, or externally applied forces.
Another significant patent is a fast edge detection system that is tolerant of a high degree of intersymbol interference (ISI). This system improves the accuracy of edge detection under challenging conditions. It utilizes an amplified and filtered first derivative signal, which is offset in both directions to create positive and negative offsets. These offsets serve as inputs to peak detectors, allowing for effective qualification of peaks based on modulation depth, regardless of their absolute levels.
