Abstract: A micrometer sized, single-stage, vertical thermal actuator with controlled bending capable of repeatable and rapid movement of a micrometer-sized optical device off the surface of a substrate. The vertical thermal actuator is constructed on a surface of a substrate. At least one hot arm has a first end anchored to the surface and a free end located above the surface. A cold arm has a first end anchored to the surface and a free end. The cold arm is located above the hot arm relative to the surface. The cold arm is adapted to provide controlled bending near the first end thereof. A member mechanically and electrically couples the free ends of the hot and cold arms such that the actuator bends generally at the flexure so that the member moves away from the substrate when current is applied to at least the hot arm.

Abstract: A disconnect switch for the load circuit of a vehicle battery, includes 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.
