摘要： An inflation device is provided including a shell, a pin, a restraining element, and a moveable element. The shell is adapted to be coupled to an inflation canister. The pin is positioned within the shell. The pin is adapted to open a seal of the inflation canister. The restraining element is positioned within the shell. The moveable element includes a shape memory alloy. The moveable element is moveable from a first position to a second position responsive to electrical energy sent to the moveable element. While the moveable element is in the first position, the restraining element is secured within the shell to restrain the pin from opening the seal of the inflation canister. While the moveable element is in the second position, the pin is releasable to open the seal of the inflation canister.

摘要： An inflation device is provided including a shell, a pin, a restraining element, and a barrier. The shell may be coupled to an inflation canister. The pin is positioned within the shell in order to open a seal of the inflation canister. The restraining element is positioned within the shell and is positioned to prevent the pin from opening the seal of the inflation canister. The restraining element is dissolvable. The barrier is positioned within the shell. The barrier includes a fluid resistant skin and a heating element coupled to the fluid resistant skin. The heating element may open a portion of the barrier responsive to an electrical current running through the heating element.

摘要： A linear actuator includes a plurality of sub-modules disposed in adjacent array and adapted to translate reciprocally parallel to a common axis. A plurality of shape memory alloy wires extend generally linearly and parallel to the axis, and are each connected from one end of a sub-module to the opposed end of an adjacent sub-module. The SMA wires are connected in a circuit for ohmic heating that contracts the SMA wires between the sub-modules. The sub-modules are linked by the SMA wires in a serial mechanical connection that combines the constriction stroke displacement of the SMA wires in additive fashion to achieve a long output stroke. Moreover, the sub-modules are assembled in a small volume, resulting in an actuator of minimal size and maximum stroke displacement. The sub-modules may be rods or bars disposed in closely spaced adjacent relationship, or concentric motive elements, with the serial mechanical connection extending from each motive element to the radially inwardly adjacent motive element, whereby the innermost motive element receives the sum of the translational excursions of all the motive elements concentric to the innermost element. The SMA linear actuator includes a restoring spring assembly having a restoring force that decreases with increasing displacement to minimize residual strain in the SMA components. The SMA wires are connected for ohmic heating in various series and parallel circuit arrangements that optimize force output, cycle time, current flow, and ease of connection.
