Thaddeus J. Stefanov-Wagner 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: 11945279
    Abstract: A motion control system is coupled to a first mass and a second mass and is configured to regulate motion of the first mass with respect to the second mass. The motion control system is configured to increase a contact area between the second mass and a surface on which the second mass rests by increasing a displacement of the motion control system from a neutral position in a direction toward the first mass.

  • Patent number: 11046143
    Abstract: Some embodiments provide a fully-actuated suspension system which can provide adjustable displacement of a sprung mass from a neutral suspension position over an unsprung mass. The system includes a variable pressure air spring which can adjust the neutral suspension position and execute low-frequency displacements and a hydraulically-driven piston which can execute high-frequency displacements. The system can communicate information to a driver, via haptic feedback provided via actuator displacements, which can augment the driver's situational awareness. The system can provide augmented vehicle braking via displacing the unsprung mass of the vehicle towards the surface upon which the vehicle rests to increase the normal force and contact area of the unsprung mass on the surface, unload torsion of the wheel induced by applied braking pressure to the wheel, etc.
