This invention relates to a support pad formed of a shock absorbing material capable of absorbing energy resulting from vibration and gravitational forces acting on a battery disposed in engagement with the support pad and, correspondingly, transferring gravitational forces that occur along a z-axis resulting from up and down movement of the battery and dispersing these gravitation forces along an x-axis, a y-axis and the z-axis so as to reduce the impact shock on the battery by between about 65% to about 80% and, in doing so, prolonging the performance and life-cycle of the battery.

A tri-adaptive apparatus is disclosed and configured for functioning as a dynamic force isolation and dampening metamaterial that reduces the transmission of dynamic forces between a dynamic force source and an object. In at least one embodiment, the apparatus provides at least one cell unit that provides a pair of opposing first and second cell plates, between which is positioned at least one spring, restrainer and dashpot. An outer surface of the first cell plate is positioned in contact with the dynamic force source. An outer surface of the second cell plate is positioned in contact with the object. The at least one spring, restrainer and dashpot are configured for transferring dynamic force energy mutually between one another while deforming mechanically in response to the dynamic forces transmitted by the dynamic force source.

A pseudo feature for a suspension and method of manufacture are described. The pseudo feature for a suspension includes a first constraining layer; a second constraining layer; and a damping layer arranged between the first constraining layer and the second constraining layer.

The present invention is directed to three dimensional weaves composed of wires or yarns that offer the potential for damping not achievable with solid materials, including high temperature damping. Three damping mechanisms have been identified: (1) Internal material damping, (2) Frictional energy dissipation (Coulomb damping), and (3) inertial damping (tuned mass damping). These three damping mechanisms can be optimized by modifying the wire material chemistries (metals, ceramics, polymers, etc.), wire sizes, wire shapes, wire coatings, wire bonding, and wire architecture (by removing certain wires). These have the effect of modifying the lattice and wire stiffnesses, masses, coefficients of friction, and internal material damping. Different materials can be used at different locations in the woven lattice. These design variables can also be modified to tailor mechanical stiffness and strength of the lattice, in addition to damping.

An apparatus is provided that includes a structure. This structure includes a first skin, a second skin and a cellular core connected to the first skin and the second skin. The cellular core includes a cantilevered damper and an internal cavity between the first skin and the second skin. The cantilevered damper projects into the internal cavity. The cantilevered damper includes a plurality of damper masses and a plurality of damper arms interconnecting the plurality of damper masses together.

A flywheel for example to a sport training or a rehabilitation machine, is linked to a hauling cable through a system of pulleys, including, in a well-known way, at least a disk-shaped part (4) rotating about a central axis (5) and incorporates a series of weights (6) that, depending on their distribution and their own weight provide a given moment of inertia. Starting from this already known configuration, the flywheel (1) is distinguished in that it has a moving coupling means (7) that allows the variation of the position of the weights (6) on the disk (4) of the wheel and to modify the moment of inertia, without it being necessary to withdraw or replace any of the weights (6) or the disk (4).

A cooking appliance including a cooking room; and a rack assembly removably installed in the inside of the cooking room. The rack assembly includes a stationary member fixed in the inside of the cooking room; a moving member configured to slide out of the cooking room; a locking device installed in the stationary member, and configured to lock the stationary member to prevent the stationary member from escaping from the inside of the cooking room; and a noise reducing member configured to reduce noise that is generated when the locking device contacts with at least one of the stationary member and the moving member.

A press on shoe cover includes a bottom layer and at least one bistable spring band. The bottom layer is sized to cover at least a bottom of a shoe. The at least one bistable spring band is attached to the bottom layer. The at least one bistable spring band having a stable planar position and a bias coiling position. The stable planar position is configured to hold the bottom layer flat. The bias coiling position is configured to wrap the bottom layer around at least the bottom of the shoe. When the shoe cover lays flat on a surface and the bottom of the shoe is pressed down on the shoe cover, the bistable spring band is configured to move to the bias coiling position thereby wrapping the bottom layer around at least the bottom of the shoe and securing the shoe cover on the bottom of the shoe.
