    摘要： A mechanical system for selectively moving a load a motive distance comprises an actuator operable for applying a force to the load. The actuator includes an active material element having a variable property. A controller is connected to the actuator and operable for sending a first stimulus to the actuator to shift the actuator from a first state to a second state. The second state is associated with detecting the onset of actuation for the actuator. The controller is operable to send the priming stimulus level to the actuator to shift it to the primed state. The actuator includes a priming device operable for determining the onset of actuation of the first active material element.

    摘要： An actuation assembly adapted for driving a load, and protecting against overload conditions, includes an actuator defining a stroke, and a resistive member, such as a superelastic shape memory alloy spring, drivenly coupled to the actuator, so as to be displaced over the stroke when an overload condition exists, and defining a non-linear force versus displacement profile.

    摘要： A quick-return active material actuator adapted for more rapidly returning a load, so as to reduce the de-actuation time of a system, includes in a first aspect a thermally activated active material actuation element drivenly coupled to the load, an active material de-actuation element drivenly coupled to the load non-antagonistic to the actuation element, and a reconfigurable mechanism interconnecting the elements and load, wherein the de-actuation element and mechanism are cooperatively configured to return the load while the actuation element is still activated, and, in a second aspect a thermally activated active material actuation element drivenly coupled to a biased load and operable to autonomously release, so that the load is caused to be returned while the actuation element is still activated, and subsequently re-engage the load.
