Simple switch actuated by force applied over wide solid angle
Electric switch can be actuated /closed/ by a force applied from any direction within a hemispheric envelope. The switch is comprised of a flexible, electrically conductive reed holding a conductive contact disc, mounted concentrically within a conductive tube.

Electromechanical rotary actuator operates over wide temperature range
Electromechanical rotary actuator, which operates over wide temperature range, contains a spring stop which has been calculated to limit internal deceleration loads to a magnitude equal to stall torque. Cryogenic capability is obtained by using dry lubricant on the gears and no lubrication on the bearings.

Electrothermal linear actuator
Converting electric power into powerful linear thrust without generation of magnetic fields is accomplished with an electrothermal linear actuator. When treated by an energized filament, a stack of bimetallic washers expands and drives the end of the shaft upward.

Piezoelectric linear actuator
Actuator exerts linear force that is controllable and reproducible to microinch tolerance. It is constructed for extremely accurate control of a valve but can also be used as a variable venturi meter, micropositioner, microthruster, and in fluidics and reaction-control systems.
