  • Torsional vibration damper with adjustable tuning
    Patent number: 10683909
    Abstract: The disclosed invention is a novel method for constructing a Torsional Vibration Damper where the device can be radially installed onto a fully assembled vibrating shaft or flange. Furthermore, the device can be adjusted for frequency during its assembly, essentially eliminating the need for multiple parts, and simultaneously eliminating human/machine error from switching parts across vehicular platforms due to their identical visual appearance.

  • Adjustable negative stiffness systems
    Patent number: 10260586
    Abstract: A variable stiffness structure includes a first negative stiffness element configured to buckle in a first direction, a second negative stiffness element configured to buckle in a second direction opposite to the first direction, and an actuator operatively coupled to ends of the first and second negative stiffness elements to control a stiffness of the variable stiffness structure. The first negative stiffness element and the second negative stiffness element are mode-3 buckling beams.
