  • Self tuning vibration absorber
    Patent number: 9296476
    Abstract: A system and method to adjustably create a reacting force in response to a vibrating force of a vibrating structure. The system includes an adjustable vibration absorber that creates a range of reacting forces. The method includes continuously monitoring the reacting force and the vibrating force with a sensor system operably associated with a control unit having an algorithm to determine if adjustment of the vibration absorber is required. If required, the control unit commands a driver to selectively adjust the vibration absorber such that the reacting force equals the vibrating force.
    Type: Grant

  • Variable stiffness support
    Patent number: 8746649
    Abstract: A system and method to control vibrations exerted on a non-vibrating structure. The system includes an adjustable variable stiffness support securely attached to both the non-vibrating structure and a vibrating structure. A driver operably associated with the variable stiffness support is configured to selectively adjust the variable stiffness support. A control system in data communication with both a sensor system and the driver includes an algorithm to determine whether adjustment of the variable stiffness support is required.

  • Self tuning vibration isolation system
    Patent number: 8731743
    Abstract: A system and method to isolate vibrations from a vibrating structure. The system includes an adjustable vibration isolator that creates a reacting force matching the vibratory force of the vibrating structure. The method includes continuously monitoring the reacting force and vibratory force with a sensor system operably associated with a control unit having an algorithm to determine if adjustment of the vibration isolator is required. If required, the control unit commands a driver to selectively adjust the vibration isolator.
