Latest Patents
One of his latest patents is the "Bending beam load cell with torque sensitivity compensation." This invention allows for compensation of side-to-side off-center load sensitivity through simple electrical adjustments. By bonding a pair of shear sensing strain gauges to each bending beam, the load cell can measure torque effectively. The design incorporates bridge circuits that enable varying torque sensitivity correction by adjusting a trimming resistor. Additionally, it includes components for compensating front-to-back off-center load error and zero adjustment. The load cell can also be hermetically sealed before any compensation of offset load errors is performed.
Another notable patent is the "Composite load cell." This invention presents a low-cost strain gauge load cell that maintains accuracy and stability through a composite structure. The sensing element is formed from a load cell quality material, such as metal or a metal alloy, while the adjoining non-sensing elements are made from molded plastic. The design ensures stable and secure joints between the sensing and non-sensing elements, utilizing various structural manufacturing methods. This composite load cell structure is versatile and applicable to many different load cell designs.
