Abstract
A shape memory alloy (SMA) actuated device capable of stress inducing the SMA to its martensite state to reset the device. The device having at least one SMA wire utilized to move a movable member from a first position to a second position. The device further configured to utilize force from a first source to reset the device when the SMA is at or below the first temperature, and utilize force from at least a second source to reset the device when the SMA is above the first temperature.
