摘要： A flexible VLSI film containing shape memory alloy SMA actuator elements (105) and associated control and driver circuitry is wrapped around any bendable element such as a flexible, hollow tube, catheter tube or the like. The SMA actuator elements (105) are thus spatially distributed around the circumference of the bendable element. The SMA actuator elements (105) are selectively resistively heated with an electric current through associated decode and driver circuitry, thereby causing a portion of the film to contract. The radical distribution of the SMA actuator elements (105) across the surface of the VLSI actuator film is such that when properly activated, a device sheathed with the VLSI film is capable of executing highly dexterous maneuvers in three-dimensional space, which was not heretofore possible. The actuator elements are self-guided in that control circuitry, decode circuitry and associated microprocessors, including position mapping means are fabricated in VLSI integrally with the SMA actuator elements. Alternatively, a microprocessor controller may be located at a remote location while communicating with associated driver circuitry on the actuator film.

摘要： The invention relates to a disconnect switch for the load circuit of a vehicle battery, comprising a movable contact element (81) and a stationary contact element (64) that are linked with a locking mechanism. For releasing the locking mechanism a shape-memory alloy release element (4) is used that contracts when heated. For closing the locking mechanism a shape-memory alloy spring element (110) is provided that induces closure of the mechanism by expansion.

摘要： A T-shaped member is pivotally mounted to a support plate, and has first and second shape memory wires attached at first ends thereof to opposing portions of the T-shape. Second opposing free ends of the shape memory wires are secured to the support plate. Electrical current is conducted alternately through the first and second shape memory wires to cause the wires to contract in alternating tandem, to thereby cause the T-shaped member to move between first and second positions. Pivotal movement of the T-shaped member can be used to actuate and/or reactivate a switch device.

摘要： Remote control means for adjusting the orientation of a controlled member, e.g. a vehicle rearview mirror (10), comprises a pivot bearing (32) for supporting the controlled member (10) on a base member (34), means for applying a frictional force to the pivot bearing (32) so as to resist pivotal movement of the controlled member. At least two springs (20, 22) formed of a shape memory alloy, connect the controlled member (10) to the base member (34) on opposite sides of the pivot bearing (32), each spring (20, 22) being so constructed so as to exert sufficient force to overcome the friction of the pivot bearing (32) when the alloy is in its resilient phase but insufficient force to overcome said friction when the alloy is in its non-resilient phase. The springs (20, 22) are heated electrically in order to cause them to change phase.

摘要： The invention relates to a bistable electrical switch, comprising a spring (101) which is configured in the form of a bistable elastic spring and which supports contact elements (114, 116) on the support strip (104) of the spring; and at least one driving element consisting of shape memory material per control state, for driving the spring. The spring has a leaf (110) which is permanently clamped at one end (102) and which is subjected to a compressive strain in the direction of its longitudinal extension. Buckling causes the leaf to yield to one side, into one of two stable terminal states. The areas of the spring adopt different lateral positions in the stable terminal positions. The driving elements (118, 119) act on the free end of the leaf and cause the leaf to switch to the second stable terminal state as a result of the inclination of the free end (104).
