| 20120305698 | Method and Apparatus for Actively Manipulating Aerodynamic Surfaces - A method and apparatus is provided, including an actuator system that may be connected to a wing frame for controlling an active element. The actuator system may include sliding elements movable along an axis parallel to the span-wise axis of the wing. The sliding elements may be connected to fixed elements and a crank element, the crank element generally comprising a beam element and a cross-axis flexure pivot element. The beam element may be offset from the pivot element so that the crank element is rotatable about the pivot element with a negative stiffness under an external force that tends to pull the sliding elements away from the fixed elements. | 12-06-2012 |

| 20130287571 | ELECTRICAL WIRING SYSTEM FOR A ROTOR HUB - The electrical harness system is configured for routing a harness between a rotor yoke and a rotor blade. A recess in an inboard cap member is configured to house a connector and an associated harness. As the recess extends along a radial path in the chordwise direction of the rotor blade, the harness is configured to lie within the recess. Operationally induced centrifugal forces promote positioning the slack of harness within the recess, while the slack in the harness remains available for relative dynamic movements between the rotor blade and the rotor yoke. Such a routing of the harness reduces aerodynamic drag and minimizes damage that could otherwise occur to the harness. | 10-31-2013 |

| 20120165151 | SYMMETRICAL TRACTION DRIVE - Disclosed is a symmetrical traction drive that utilizes multi-diameter rollers having traction surfaces for transferring rotational mechanical energy between the shaft and a transfer gear. Multi-diameter rollers are mounted in carriers disposed between two substantially symmetrical ring gears. Sloped traction surfaces of the ring gears mate with inner traction surfaces on both sides of the multi-diameter rollers. Since force is applied to the inner traction surfaces on both sides of the multi-diameter rollers, forces are substantially equalized on each side of the multi-diameter rollers. An outer traction surface of the multi-diameter roller interfaces with a traction surface on the shaft. Speed reduction ratios of at least 20:1 or greater can be achieved. The high speed drive may include exhaust turbines, steam turbines, including a Tesla turbine or Schumacher turbine, compressors, combinations of turbines and compressors, high speed pumps, dentist drills, or other devices that operate with high rotational speed. | 06-28-2012 |
| 20130017920 | HIGH TORQUE TRACTION DRIVE - Disclosed is high torque traction drive. The high torque traction drive utilizes planet gears that engage the inner mesh of a ring gear. The planet gears are mounted in rollers that have inner traction surfaces that engage sloped ring traction surfaces on traction rings that are attached to the ring gear. The sloped traction interface causes the rollers to move inwardly when forced toward the traction rings. The inward force on the rollers creates a shaft traction interface between a shaft and outer traction surfaces on the roller, so that rotational mechanical energy is effectively transferred between the rollers, the shaft and the ring gear. High rotational speeds can be achieved with a high degree of torque. Speed reduction ratios of at least 10:1 or greater can be achieved. The high speed drive may include exhaust turbines, steam turbines, including a Tesla turbine or Schumacher turbine, compressors, combinations of turbines and compressors, high speed pumps, dentist drills, or other devices that operate with high rotational speed. | 01-17-2013 |
