    Abstract: An actuator device comprises an enclosed volume region defined by a housing body and a movable surface, such that at least a portion of the enclosed volume region is expandable from an initial volume state to an enlarged volume state. An electrically conductive porous material is disposed in the enclosed volume region, wherein the electrically conductive porous material has a mass density of from about 0.5 mg/cc to about 100 mg/cc, and wherein at least about 90% of the electrically conductive porous material is a carbonaceous material. A first electrode and a second electrode are configured to pass an electric current through the electrically conductive porous material. When an electric current is passed through the electrically conductive porous material, air disposed in the enclosed volume region expands and displaces the movable surface. A method of displacing a movable surface in an actuator device is also described.

    Abstract: Embodiments generally relate to fixturing devices for supporting a workpiece, the devices including modularized cantilevered and fixed beam fixing elements. Each module includes a compliant beam and an interface element in contact with the workpiece and a portion of the compliant beam for transmitting a contact force between the workpiece and the beam. Dynamic adaptability of the beam is configured by selectively varying beam stiffness by varying either beam length or beam width. Varying a width can include varying a beam width, and/or breadth. In a further embodiment, the compliant beam fixed at both ends is slidable in a longitudinal direction of the beam such that a portion of the interface element slides along the beam, thus dynamically adapting the beam stiffness according to a force applied to a workpiece.

    Abstract: A motion conversion system is described. The motion conversion system comprises a first torsional member operative for rotating in a first direction. A second torsional member is offset a distance from the first torsional member, wherein the second torsional member is operative for rotating in a direction opposite from the first direction. And, a lateral member has a lower surface connected to the first and second torsional members. Wherein, translational movement of the lateral member results from rotational movement of the first and second torsional members.
