David F Dodgen is a notable inventor based in Boca Raton, FL (US). He has made significant contributions to the field of printing technology, holding a total of 3 patents. His work primarily focuses on improving the efficiency and accuracy of print head motor control systems.

Latest Patents

One of his latest patents is the "Print head motor control system using analog and digital feedback." This control system is designed for a bidirectional printer, allowing the print head carriage to move at varying speeds across different printing lines. It utilizes a microcomputer to generate a desired velocity profile for the carriage motion, continuously comparing it with the actual velocity. The error voltage generated is then used to control pulse width modulator circuitry, which supplies driving power to the carriage drive motor.

Another significant patent is the "Print head motor control with stop distance compensation." This system ensures equal stopping distance in the margin during both high and low-speed operations. It achieves this by delaying the initiation of stopping carriage motion when printing at low speed, allowing the carriage to travel further into the margin. This distance is controlled to match the travel distance at the end of a line printed at high speed.
