Patent ID: 8746649

Claim:
A floor mounting system, comprising: a non-vibrating structure; a vibrating structure that exerts a vibratory force on the non-vibrating structure; and a vibration isolation system, having: an adjustable variable stiffness support securely attached to both the non-vibrating structure and the vibrating structure, the variable stiffness support being configured to isolate the vibratory force exerted on the non-vibrating structure; a driver operably associated with the variable stiffness support, the driver being configured to selectively adjust the variable stiffness support; a sensor system, having: a first sensor associated with the variable stiffness support; and a second sensor associated with the vibrating structure; and a control system in data communication with both the sensor system and the driver, the control unit being configured to analyze a first output signal from the first sensor and a second output signal from the second sensor and configured to command the driver to adjust the variable stiffness support, the control system having: an algorithm, having: a linear envelope detector; a differentiator; and a sign comparator; wherein the first signal and the second signal pass through the linear detector for determining a first amplitude of the first signal and a second amplitude of the second signal, then thereafter a slope of a ratio of the first amplitude and the second amplitude is compared with the sign comparator; wherein if the slope is not equal to zero, then the variable stiffness support is adjusted accordingly; and wherein the vibration isolation system continuously monitors the vibratory forces and adjusts the variable stiffness support accordingly.
