    Abstract: A tunable vibration isolator (451, 551, 651, 681, 691, 721, 801, 901, 973) with active tuning elements (473, 475, 573, 673, 675, 689, 705, 707, 745, 747, 747, 819a, 819b) having a housing which defines fluid chambers. A piston (455, 555, 655, 695, 725, 805, 970) is disposed within the housing. A vibration isolation fluid is disposed within the fluid chambers. A passage (463, 563, 663, 735, 881, 904) having a predetermined diameter extends through the piston to permit the vibration isolation fluid to flow from one fluid chamber to the other. The tunable vibration isolator may employ either a solid tuning mass approach or a liquid tuning mass approach. In either case, active tuning elements, or actuators, are disposed in the fluid chambers to selectively tune the vibration isolator.

    Abstract: A floor mounting system including an array of variable stiffness supports disposed between and coupled to a base structure and a floor member, and a control system conductively coupled to each variable stiffness support for selectively varying the stiffness of each variable stiffness support is disclosed. Each variable stiffness support has a support housing that is configured to adjust the orientation of an internal elastomer assembly. The support housing includes an adjustment mechanism, and the elastomer assembly includes an outer ring that encircles an elastomeric material, a central bushing embedded in the elastomeric material, and a plurality of shims embedded in the elastomeric material in a parallel plane.
