Abstract: A nanometer-scale precision actuator comprises a base, an intermediate structure, an output interface, and two linear elements producing a controllable extension in the same longitudinal direction, each between a first and a second end. A first of the two elements has a first end fixed onto the intermediate structure and a second end fixed onto the base, a second of the two elements has a first end fixed onto the intermediate structure and a second end fixed to the output interface. The base and the intermediate structure are positioned in such a manner that the controllable extension of the second element produces a displacement of the actuator in a first direction and the controllable extension of the first element produces a displacement of the actuator in a second direction, opposite to the first direction, with respect to the base.

Abstract: The ultrasonic tubular transducer is activated at the centre thereof by two symmetrical electromechanical converters. The vibration generated by the two electromechanical converters is converted and then transmitted to the tube via a coupler. The ultrasonic transducer can be vibrationally isolated from the interfaces thereof by caps equally suitable for connecting the transducer to a stationary frame, a free end or another similar ultrasonic transducer. A device for pre-stressing electromechanical converters has a hole bored at the centre thereof in order to allow cables from the transducer as well as from adjacent transducers to pass therethrough.

Abstract: A piezoelectric device comprises a fixed frame and a mirror carrier defining several support points securing a mirror. The mirror carrier is mounted rotatable. Several piezoelectric actuators are fixed to the support and deform independently in translation in a first direction. Each piezoelectric actuator moves the support area of the mirror carrier. The mirror carrier defines several attachment points. Each attachment point connects the mirror carrier mechanically with a piezoelectric actuator. The support points and attachment points are distinct from one another. The mirror carrier defines a plurality of flexion areas. The support points are movable with respect to one another. The piezoelectric actuators supplied in push-pull mode drive the support points making the mirror rotate perpendicularly to the first direction.

Abstract: The actuator comprises a movable armature swivelling with respect to a stator provided with flanges on which magnets are fitted and a coil fitted around one of the flanges. The magnets have an axial magnetisation in a z axis and are aligned in an x axis. The movable armature is arranged between the magnets in the x axis. The movable armature is mounted on a guide imposing swivelling around a y axis perpendicular to the x and z axes. The movable armature is separated from the magnets by air-gaps. Each magnet forms a static magnetic circuit with one end of the movable armature and one of the flanges. The coil forms a dynamic magnetic circuit with the ends of the movable armature and the flanges.
