Patents by Inventor Mary B. Wigginton

Mary B. Wigginton has filed for patents to protect the following inventions. This listing includes patent applications that are pending as well as patents that have already been granted by the United States Patent and Trademark Office (USPTO).

  • Patent number: 11702051
    Abstract: Vehicles and methods of operating vehicles are disclosed herein. A vehicle includes a main frame, a work implement, and a control system. The work implement is supported by the main frame and configured to carry a payload in use of the vehicle. The control system is supported by the main frame and configured to control operation of the vehicle. The control system includes a payload measurement system configured to provide payload input indicative of a variable payload carried by the work implement in use of the vehicle and a controller coupled to the payload measurement system.
    Type: Grant

  • Patent number: 11530525
    Abstract: A work machine includes a chassis, a boom coupled to the chassis, and a work implement coupled to the boom and movable relative to the chassis. In system may further include dynamic payload weighing system configured to measure the payload weight on the work implement. The system may also include an electrohydraulic system controller in communication with the dynamic payload weighing system and an electrohydraulic control valve electrically coupled to the electrohydraulic system controller and moveable to a plurality of weight-specific valve positions based on the measured payload weight on the implement.

  • Patent number: 11421399
    Abstract: A load sensitive ride system and method is disclosed for a vehicle with an implement movably attached by a boom cylinder. The system includes a payload weight measuring system that measures payload weight and generates a signal indicative of the payload weight, a ride control circuit that adjusts hydraulic flow to and from the boom cylinder; and a controller that receives the signal indicative of the payload weight, and sends compliance commands to adjust ride control compliance based on the signal indicative of the payload weight. The system can include a tire inflation system that adjusts tire pressure. The controller can send inflation commands to adjust tire pressure based on the signal indicative of the payload weight. The compliance commands can depend on the components and compliance adjustment methods of the ride control circuit.

  • Patent number: 11131083
    Abstract: A work machine that has a chassis, a payload section, a controller, a payload sensor in communication with the controller, and an orientation sensor that identifies the orientation of the work machine to the controller. The controller determines a center of gravity for the work machine considering a payload weight identified by the payload sensor and sends an alert when the location of the center of gravity and the orientation of the work machine create an unstable condition.
