Latest Patents
Cynthia's latest patents include a "Method and apparatus for controlling an implement of a work machine." This invention describes an apparatus designed to controllably move a work implement connected to a work machine. The implement is movable in response to the operation of a hydraulic cylinder. The apparatus features an operator-controlled joystick that generates an operator command signal, indicating the desired velocity of the work implement's movement. Additionally, cylinder position sensors produce signals in response to the position of lift and tilt cylinders. A valve assembly receives an electrical valve signal and controllably provides hydraulic fluid flow to the respective hydraulic cylinders, allowing for precise movement in accordance with the operator's commands.
Another patent under her name is also titled "Method and apparatus for controlling an implement of a work machine." This invention similarly focuses on the controllable movement of a work implement through a hydraulic cylinder. It includes a joystick position sensor that generates an operator command signal based on the joystick's position. Boom and bucket angle sensors provide additional data, which is processed by a microprocessor-based controller to modify the operator command signal and produce an electrical valve signal. This signal is then used to control hydraulic fluid flow to the hydraulic cylinder, ensuring accurate and responsive operation.
