摘要： A method of fabricating a current control device is presented. The method impregnates a pressure conduction composite within a current control device with a fluid additive via suffusion. The suffusion process is performed by placing the pressure conduction composite within a bath of a liquid additive. The method generally includes the steps of mixing a compressible non-conductive matrix and conductive filler, forming a pressure conduction composite composed of the non-conductive matrix having the conductive filler electrically isolated therein, suffusing the composite within a bath so as to impregnate the composite with an additive, and attaching a pair of conductive plates to the composite. Alternate methods include attaching non-conductive plates to the composite, forming pores within the pressure conduction composite, and inserting a temperature responsive material into a porous composite.

摘要： An isolator mount for the active dissipation of shocks and vibrations is presented. The invention includes at least one energy dissipating layer and deflectable elements so as to provide soft damping for small disturbance excitations, yet remaining sufficiently stiff to mitigate large shocks. The mount transfers mechanical energy to the dissipating layers via the device structure. Dissipating layers convert shock and vibration energies to either heat or magnetic energy.

摘要： A passive isolator mount capable of dissipating shocks and vibrations as either heat or magnetic energy is presented. The passive isolator includes a pair of L-shaped or C-shaped brackets capable of withstanding repeated deflections and strains, energy dissipating layers disposed along each bracket, and a bond layer. The energy dissipating layers are composed of a rare earth element or alloy, a ferromagnetic shape alloy, a magnetic shape memory alloy, a magnetostrictive alloy, a magneto-mechanical alloy, a super-elastic alloy, or a combination thereof. The bond layer is disposed between and adheres one energy dissipating layer along a first bracket to an energy dissipating layer along a second bracket so that the resultant passive isolator is C-shaped. Energy dissipating and bond layers completely bisect the passive isolator either widthwise through the thickness of the L-shaped brackets or lengthwise through the thickness of the C-shaped brackets.

The invention includes at least one energy dissipating element disposed between deflectable elements so as to provide soft damping for small disturbance excitations, yet remaining sufficiently stiff to mitigate large shocks. The mount transfers mechanical energy to the dissipating element via the device structure. Dissipating element mitigates the energy in shocks and vibrations as either heat or magnetic energy. A snap-together modular embodiment enables the coupling of two or more isolators for use within a wide variety of shock and vibration applications. Quasi-static tuning of one or more mounts comprising a snap-together module facilitates an active response to changing conditions.
