| 416079000 | OSCILLATORY REACTION MOTION | 7 |
| 20110076144 | Fluid Interacting Device - A rotary turbine including at least one blade is disclosed. The rotary turbine includes a blade arrangement in which the orientation of the at least one blade movably changes relative to the fluid flow and also changes relative to an orbital path taken by the rotary turbine thereby increasing flow area usage and minimizing friction. Certain embodiments of the present disclosure include a rotary turbine with blade orientations that are linearly coupled to the orbital orientation of the turbine. Other embodiments of the present disclosure include a rotary turbine with blade orientations that are non-linearly coupled to the orbital orientation of the turbine. | 03-31-2011 |
| 20110255971 | APPARATUS FOR OSCILLATING A FOIL IN A FLUID - The invention relates to an apparatus for oscillating a foil in a fluid. The apparatus according to the invention comprises a first crank mechanism and a second crank mechanism connected to a foil. Said first crank mechanism and said second crank mechanism have different crank pin offsets, are functionally connected such that when driven the speed of revolution of said first crank mechanism is the same as the speed of revolution of said second crank mechanism, and are out of phase with each other. | 10-20-2011 |
| 20130195659 | Ornithopter aircraft transmission - This invention is regarding an aircraft transmission that is designed to enable an ornithopter aircraft to take off vertically by generating lift through precision controlled oscillating propellers or wings, similar but unlike a helicopter rotor blade and has the uncanny ability for aerobatic flight. A gearless infinite variable oscillating transmission for ornithopter aircraft oscillatory motion propulsion, wherein the oscillatory motion is generated by a wobble plate and propulsive motion is propellers, wings, or any other propulsive action or phenomena, characterized by two parts, or pairs of elements, of the same potential capacity, which oscillate in series on opposed fronts with each propulsion unit capable of operating independently of the other. Infinite variable oscillating transmission is used to power numerous mechanical devices. | 08-01-2013 |
| 20130216381 | OSCILLATING FOIL TURBINE - An oscillating foil turbine has a foil having a first fluid dynamic surface for producing lift in a fluid flow, a support for the foil, and a second fluid dynamic surface, wherein the support allows for cyclic motion of the first and second surfaces with respect to each other. A driven member is provided to tap energy from flow throughout each cycle. Throughout at least part of the cyclic translation, the fluid dynamic surfaces are oriented sufficiently parallel, and separated by a distance that is sufficiently small, to achieve a substantial wing-in-ground effect. | 08-22-2013 |

| 20160252105 | CANTILEVER FAN | 09-01-2016 |
| 416082000 | Relatively movable working member portions | 1 |
| 20110064576 | Wind Oscillator for Power Generation - A wind oscillator configured for power generation is provided. The wind oscillator includes an upwardly oriented elongate rotatable support beam configured to rotate to enable the wind oscillator to be approximately oriented with respect to a wind direction, a bracket supported by the support beam, the bracket extending transversely and outward therefrom, a shaft operably connected to the bracket at a first end of the shaft, and a gear attached to a second end of the shaft. The wind oscillator further includes an oscillating arm pivotably disposed approximately atop of said support beam, wherein the shaft is disposed upon the oscillating arm, and the oscillating arm being configured to move upwardly and downwardly with respect to the support beam in a reciprocating arrangement, an elongate transverse bar supported by a first end of the oscillating arm, elongate first and second wing bars oriented transversely with respect to the elongate transverse bar, wherein the oscillating arm, the elongate transverse bar, and the wing bars are on approximately a same plane, and a leading wing rotatably connected to and extending between the first and second wing bars. | 03-17-2011 |

| 20160146211 | OSCILLATING MECHANISM AND CEILING FAN USING THE SAME - A ceiling fan with an oscillating mechanism includes a clutch member for adjusting the angle of oscillation according to a user's need. When the motor is actuated, the rotating torque induced by the motor and the transmission mechanism is less than the rotational resistance of the clutch member such that the motor may drive the fan to oscillate. Further, when the user applies an external rotational force greater than the rotational resistance of the clutch member, the user can swing the fan to any angle as desired without rotating or shifting other members except the fan and the fan suspension tube. In this manner, undesired damage of the mechanism or motor due to inappropriately applied external force can be avoided efficiently. | 05-26-2016 |
