    Abstract: Dielectric barrier discharge plasma actuators are described. In one embodiment, a fluid flow actuator includes: a dielectric sheet; and a first electrode of a dielectric barrier discharge-direct current augmented (DBD-DCA) actuator disposed on a first face of the dielectric sheet. The first electrode is exposed to a surrounding fluid. The fluid actuator also includes a second electrode of the DBD-DCA actuator disposed on a second face of the dielectric sheet. The second face of the dielectric sheet is opposite from the first face of the dielectric sheet. The first electrode and the second electrode are configured for receiving an alternating current (AC) voltage configured to locally ionize the fluid and to generate ions. A third electrode located downstream from the first electrode and the second electrode. The third electrode is configured for receiving a direct current (DC) voltage configured to accelerate the ions.

    Abstract: The present disclosure provides a mechanical linkage device including a ground link comprising an inverse center linked to one end of the ground link. The mechanical linkage device further includes a movement link connecting the ground link to a control point. The mechanical linkage device further includes two or more linkages having a first link of the two or more linkages including a first end linked to the control point and a second link of the two or more linkages including second end linked to an end point. The end point, the control point, and the inverse center of the ground link remain co-linear. The control point and the end point have an inverse relationship such that movement of the control point is inversely translated to the end point. The ground link, the movement link, and at least one of the two or more linkages do not all he in a plane throughout an entire range of motion of the mechanical linkage device.
