Title: Innovations of Daniel C. Garvey
Introduction
Daniel C. Garvey is a notable inventor based in Fort Collins, Colorado. He has made significant contributions to the field of engineering, particularly in the area of locomotive technology. With a total of five patents to his name, Garvey's work reflects a commitment to enhancing the efficiency and safety of locomotive operations.
Latest Patents
Garvey's latest patents include a "Locomotive Wheel Slip Controller," which utilizes PID controllers to manage traction wheels during normal locomotive operation. This innovative controller monitors multiple independent wheel slip indicators to quickly detect excessive wheel slip. When such a condition is identified, the motor control from the operative PID controller is suspended, allowing a wheel slip compensator to take command of the traction wheel drive motors. This compensator dynamically adjusts the motors based on the detected wheel slip, ensuring a smooth return to normal operation once the issue is resolved.
Another significant patent is the "Method and Apparatus for Iterated Determinations of Sensed Speed." This invention employs a programmed digital computer to iteratively determine the actual speed of an engine while updating a fuel rate command signal. By sensing the engine crankshaft and generating a predetermined number of pulses during one revolution, the system effectively eliminates torsionally induced speed fluctuations. Each iteration not only signals the speed but also updates the fuel rate command as a PID function of the speed error, allowing for automatic tuning adjustments.
