Abstract: The VEHICLE WITH TRAVELING WAVE THRUST MODULE APPARATUSES, METHODS AND SYSTEMS include force or forces applied to an arc-like flexible sheet-like material to create a deformed crenated strip fin with strained-deformations. The strained-deformations take on a sinusoid-like form that express the internal energy state of the flexible sheet-like material after it has been configured into a crenated strip fin. After being incorporated into a mechanism with couplings that prevent the crenated strip fin from returning to its un-strained state, the strained-deformations persist. Actuators may be used to sequentially rotate vertebrae attached to the fins causing the travel of sinusoid-like deformations along the fins. The fin, fin actuator or actuators, power source and central controller may be incorporated into a thrust module. Two thrust modules coupled to a central body via roll actuators and flexible coupling members may form a vehicle with exceptional maneuverability.

Abstract: A highly maneuverable craft, which may be lighter-than-air, is disclosed, having undulating fins of a light-weight material that may undulate along the horizontal axis of the craft and/or rotate 360 degrees and continuously about the central longitudinal axis of the craft. The fins may be actuated by motors coupled to the fins and coupled to the exterior of the craft via circumferential bands. Motion of the fins creates aerodynamic thrust. The circumferential bands may serve as tracks or channels along which the motors run, allowing the motors to travel 360 degrees or travel continuously around the exterior of the craft and thereby draw the fins about the craft. The circumferential bands may serve as reinforcing components, allowing the motors to exert torque against the body of the craft which may be thin-walled for maximum positive buoyancy. An on-board battery may power the motors via electrical circuits extending around the bands.

Abstract: The APPARATUSES, METHODS AND SYSTEMS FOR HARNESSING THE ENERGY OF FLUID FLOW TO GENERATE ELECTRICITY OR PUMP FLUID include a device which, when placed in fluid-flow, harnesses the kinetic energy of the flow to generate electricity or to perform useful mechanical work such as pumping. For example, the undulating mechanical action of traveling waves along flexible fins may be harnessed by summing the varying speeds and torques along the fins into a unified circulatory system for power take-off or fluid extraction. The device may include two fins, a chassis, and bellows/pistons/rotary vanes and the like which are connected via a circulatory system of tubes or conduits.

Abstract: The APPARATUSES, METHODS AND SYSTEMS FOR HARNESSING FLUID FLOW WITH FLEXIBLE MECHANICAL TRANSDUCERS include mechanisms that include flexible elements with strained deformations. In some implementations, oscillations of strained deformations in fins are excited by a moving fluid. By coupling the fin structure to an electrical generator and/or pump, energy from the moving fluid can be converted into electrical energy or used to perform useful mechanical work. In some implementations, the fin may be coupled to a motor or other actuator which causes the strained deformations to move, thereby imparting force onto the fluid to move or mix fluid or perform other useful work.
