| 20080272231 | Winged Device - A winged device has an axial support which is mounted for reciprocating rotary motion about a longitudinal axis of the support. A first wing vane is mounted to the axial support for rotation with the axial support. A second wing vane is mounted to the axial support. A cam follower is constrained to a defined movement path by a cam. A first connector connects the first wing vane to the cam follower such that the cam follower is moved along the cam by the first connector as the first wing vane moves with rotation of the axial support about its longitudinal axis. A second connector connects the second wing vane to the cam follower such that the second wing vane is moved by the second connector as the cam follower member is moved along the cam. The cam profile is defined relative to the axis of the axial support such that the relative orientation of the wing vanes changes as the axial support is rotated. The axial support is received by a pivot member within which the axial support can rotate about its longitudinal axis. The pivot member is driven in reciprocating angular motion about a transverse axis which crosses the longitudinal axis of the axial support, so that the axial support oscillates about the transverse axis B. | 11-06-2008 |
| 20090179108 | Biomimetic micro-aerial-vehicle with figure-eight flapping trajectory - A micro aerial vehicle includes: a fuselage; a flapping transmission mechanism mounted on a front portion of the fuselage; a flexible wing frame secured to and driven by the flapping transmission mechanism for producing a figure-eight flapping trajectory for mimicking the flight of a tiny natural flier, such as hummingbird; and a tail wing secured to a tail portion of the fuselage; wherein the flexible wing frame is formed by respectively pivotally or rotatably mounting a wing skin made of parylene foil to a pair of leading-edge arm members made of carbon fiber, and linked to the flapping transmission mechanism to thereby make a miniaturized micro aerial vehicle. | 07-16-2009 |
| 20100264262 | Inverting wing propulsion system - An inverting wing propulsion system is disclosed. A vehicle body having a left side and a right side is provided with a wing drive assembly. At least two wings are operatively associated with the wing drive. At least one wing extends from each of the right side and the left side of the body. The wings are adapted to be driven by the wing drive assembly to engage in a reciprocating motion between a raised orientation and a lowered orientation. The reciprocating motion is characterized by a downward arcuate motion, where said wings fully extend from the body so as to generate an upward thrust, and by an upward motion, where the wings are retracted so as to produce reduced, minimized or negligible downward thrust. | 10-21-2010 |

| 20120292438 | Passive Torque Balancing in a High-Frequency Oscillating System - A passively torque-balanced device includes (a) a frame; (b) a drivetrain including a drive actuator mounted to the frame and configured for reciprocating displacement, an input platform configured for displacement by the drive actuator, a plurality of rigid links, including a proximate link and remote links, wherein the rigid links are collectively mounted to the frame, and a plurality of joints joining the rigid links and providing a plurality of non-fully actuated degrees of freedom for displacement of the rigid links, the plurality of joints including a fulcrum joint that is joined both to the input platform and to the proximate rigid link; and (c) at least two end effectors respectively coupled with the remote links and configured for displacement without full actuation. | 11-22-2012 |
| 20140061379 | MOTORISED DEVICE AND METHOD OF MOVING THE DEVICE - A motorised device arranged to move using cyclic motion is disclosed. The device includes a motorised means; at least one limb coupled to the motorised means, and configured to be driven by the motorised means for moving the device; and a resilient biasing means coupled to the at least one limb to further drive the at least one limb using mechanical resonance. A related method of moving the motorised device is also disclosed. | 03-06-2014 |
| 20140158821 | Air Vehicle Flight Mechanism and Control Method for Non-Sinusoidal Wing Flapping - A flapping wing driving apparatus includes at least one crank gear capstan rotatably coupled to a crank gear, the at least one crank gear capstan disposed radially offset from a center of rotation of the crank gear; a first wing capstan coupled to a first wing, the first wing capstan having a first variable-radius drive pulley portion; and a first drive linking member configured to drive the first wing capstan, the first drive linking member windably coupled between the first variable-radius drive pulley portion and one of the at least one crank gear capstan; wherein the first wing capstan is configured to non-constantly, angularly rotate responsive to a constant angular rotation of the crank gear. | 06-12-2014 |
