Abstract:
A device for cycling a component between a first condition and a second condition includes an element and a reset apparatus connected to and driven by the element. The element is formed from a shape memory alloy, wherein the alloy is transitionable between a martensite crystallographic phase and an austenite crystallographic phase in response to a thermal energy source. The apparatus is actuatable by the element from an initial state in which the alloy has the martensite phase and the component is in the first condition, to an actuated state in which the alloy has the austenite phase and the component is in the second condition. The apparatus is resettable from the actuated state to a reset state in which the alloy transitions from the austenite to the martensite phase while the component is in the first condition, and further resettable from the reset state to the initial state.
