Abstract
Apparatus and methods for selectively providing or preventing access to areas, enclosed spaces or volumes, or for controlling the position of a pivot or hinge assembly. In one exemplary embodiment, the apparatus includes a selectively actuated or actuate-able hinge which is controlled at least in part by a shaped memory alloy (SMA) filament or filaments. Application of electrical current to the filament causes changes in the physical properties thereof, thereby allowing “ratcheted” rotation of a portion of the hinge relative to other portions. In one variant, the hinge can be remotely operated, such as via wireless or wireline communication with a remote entity such as a computer or smartphone.
