Title: Innovations by William J Graaskamp
Introduction
William J Graaskamp is a notable inventor based in Guelph, Canada. He has made significant contributions to the field of agricultural machinery through his innovative designs and systems. With a total of three patents to his name, Graaskamp has focused on enhancing the efficiency and functionality of tractor implements.
Latest Patents
One of his latest patents is the "Valve control system for hitch motor." This system controls the supply of fluid to an actuator, which in turn manages the movement of components such as tractor implement hitches. The system allows for the desired value of operating parameters to be set and compared with actual sensed values, generating a parameter error signal. A start-up control function improves the initial speed of response, ensuring that the component moves as intended.
Another significant patent is the "Implement control system." This system compares desired and actual implement draft force values to generate a draft force error signal. It effectively controls the working depth of the implement based on this error signal. A deadband mechanism ensures that only relevant signals are acted upon, allowing the system to ignore high-frequency noise while responding to true variations in draft force.
