"0021]While this invention has been discussed in terms of the bending actuator as a star decoration or a lantern, there are many more uses. One skilled in the art will recognize that this actuator can be applied to valves, blinds, plugs, door bolts, air pumps, toys, light stands, climbing devices, etc. This invention is able to actuate silently with very low weight and can be desirable in many settings. The rotational or linear motion created by the SMA strip contraction causes this invention to be extremely versatile."
