Abstract: An adjustable negative stiffness mechanism is disclosed. The adjustable negative stiffness mechanism includes a central shaft, an outer annular member extending around the central shaft, at least two negative stiffness elements extending between the central shaft and the annular member, and an actuator coupled to the negative stiffness elements. Each of the negative stiffness elements has an inner end coupled to the central shaft and an outer end engaging the annular member. The actuator is configured to compress and expand the negative stiffness elements to adjust a negative stiffness mechanical response exhibited by the negative stiffness elements.

Abstract: A bi-directional spring member is mounted to a support platform, the bi-directional spring member being coupled to a payload. The bi-directional spring member includes a non-linear spring component having a rigid member enclosing at least a portion of a compliant planar member and a linear spring component. The compliant planar member flexes in a direction opposite a direction of low amplitude vibrational forces acting on the compliant planar member to reduce vibrational forces acting on the support platform and the linear spring member flexes to reduce high amplitude vibrational forces acting on the support platform.

Abstract: A vertical-motion vibration isolator utilizes negative-stiffness-producing mechanism which includes a plurality of compressed flexures, each having a particular length in the compressed direction of the flexure and being oriented in a horizontal direction, wherein the plurality of compressed flexures are positioned relative to each other such that the length of each compressed flexure substantially overlaps the length of each of the other compressed flexures. At least some of the plurality of compressed flexures can be positioned in a stacked arrangement. The arrangement of compressed flexures forming a portion of the negative-stiffness mechanism can reduce the size of the isolator without compromising vibration isolation performance.

Abstract: A bumper for use at a loading dock has two ranges of front-to-back movement: one range for sealing the gap that might otherwise exist between the rear edge of a truck and the front face of the bumper and a second range for absorbing the impact of the truck backing into the dock. In some cases, a spring provides a relatively light sealing force between the bumper and the truck, and a compressible core provides a much greater impact-absorbing force that helps stop the rearward movement of the truck. In some embodiments, the bumper pivots by gravity when operating in the sealing range.

Abstract: A spring system for resiliently supporting a mass with respect to a base comprises a supporting member mounted for movement and which can be coupled to the mass and is bounded by a portion of a spherical surface which bears against a concentric complementary guiding spherical surface fixed with respect to the base to guide the supporting member to rotate in all directions around the center of the sphere. A circular resilient device is provided in engagement with the supporting member and is supported with respect to the base. The supporting member is coupled to the mass at a point inside the circular resilient device whereby the supporting member is tilted by radial shocks while its spherical surface is guided along the guiding spherical surface and by the deformations of the resilient device as a result thereof, a resilient couple and/or a radial resilient force is developed which tends to move the supporting member into its initial position.
