With a total of two patents to his name, Schwab's innovations reflect his expertise in designing efficient and practical solutions for contemporary challenges in engineering.

Latest Patents

Schwab’s first significant patent focuses on a **Vehicle Steering Control** system. This innovative design features a hand grip that rotates around an axis aligned with the wrist's center. The control mechanism allows for input by rotating the forearm while ensuring that any forces exerted radially or parallel to the rotation axis do not interfere with control input. A key component of this system is a transducer that senses the hand grip position, which is uniquely restrained only in rotation and protected from external forces acting on the grip.

His second patent details a **Load Lifting and Lowering Control System**. This invention presents a hydraulic control arrangement aimed at improving the lifting and lowering of loads in industrial settings. The system employs a multi-element control valve equipped with timing circuitry, effectively mitigating unwanted transient pressure surges that can occur during valve actuation. Additionally, it incorporates series-parallel oil flow paths to manage the oil direction from the load-lifting cylinder back to the reservoir when lowering loads.
