A kinetic fluid energy to mechanical energy conversion includes rotatable hubs supporting one or more independently controlled articulating energy conversion plates (“ECP”) and systems and components for alternating the independent control of each ECP in response to operating conditions thereby comprising an energy conversion regulation method. Separator plates for controlling fluid flow with respect to each ECP may be employed above and below the hub and may also be directionally altered in response to operating conditions and included within the energy conversion method.

A piezoelectric power apparatus wherein piezoelectric material forms one wall of a liquid-filled container. Water pressure within the container is made to rapidly vary either by a cam operated piston or a motor operated ball valve acting on a pressurized liquid flow. The piston reciprocates through a wall of the container to alternately increase and decrease the pressure in the liquid. The ball valve periodically interrupts the pressurized liquid flow to alternately increase and decrease the pressure in the liquid. In either case, the alternate increase and decrease in the pressure in the liquid creates pressure variations in the piezoelectric material.

Provided is a fluid flow energy harvester (10) comprising a crankshaft (12) and at least one vane (14) pivoted into a sail portion (18) and a crank portion (20) on respective sides of the pivot (16). Both portions (18) and (20) are operatively oscillatable about the pivot (16) when the crank portion (20) is operatively arranged facing into a fluid flow (22). The crank portion (20) is linked to the crankshaft (12) via a crank (24) so that operative oscillation of the vane (14) imparts rotational force to said crankshaft (12). The harvester (10) also includes a fin arrangement (26) which comprises a fin (28) arranged on, and configured to guide, the sail portion (18) of the vane (14) facing towards or in a direction of the fluid flow (22). The harvester (10) also includes a fin actuator (30) configured to control an orientation of the fin (28) relative to the sail portion (18), so that during oscillation of the sail portion (18), either a surface (32) of the sail portion or a surface of the fin (34) impedes the fluid flow (22) when a surface of the other is parallel to such fluid flow. In this manner, stalling of the vane oscillation is counteracted thereby facilitating continuous rotation of the crankshaft (12) during fluid flow (22).

A device for controlling thrust vectoring of a cyclorotor includes a control cam positionable relative to a drive shaft of a cyclorotor along each of a first axis and a second axis, where the drive shaft is rotatable about a third axis. The device may further include a frame having a plurality of sides, where the frame is disposed at least partly around the drive shaft of the cyclorotor, a first positioning assembly disposed on a first side of the frame, where the first positioning assembly is structurally configured to move the frame along the first axis, and a second positioning assembly disposed on a second side of the frame, where the second positioning assembly is engaged with the control cam and structurally configured to move the control cam relative to the frame along the second axis.

The present invention is related in general to air circulators, and in particular, to an air circulator with a vein control system to direct and adjust airflow patterns. According to an exemplary embodiment, the present invention provides adjustable, vertical veins that are attached to the outlet of a tower fan. According to a preferred embodiment, the veins are pivotally mounted in such a way that by turning a knob, the veins can either be directed into a focused air-flow pattern or adjusted to a divergent air-flow pattern, or at any setting in between.

In a rotating machine having a fluidic rotor, the rotor comprises at least one blade mounted on an arm rotating about a rotor shaft forming a main axis of the rotor, the rotor being kept by a supporting structure in an orientation such that said axis is substantially perpendicular to the direction of flow of the fluid, the blade being mounted so as to pivot about an axis of rotation of the blade parallel to the main axis. The machine comprises means for generating a relative oscillation movement of the blade with respect to the arm at the axis of rotation of the blade, in order in this way to vary the inclination of the blade during the rotation of the rotor. Said means comprise, at the arm end, a mechanism comprising a first rotating element (A; B) known as the drive element and a second rotating element (B; A) known as the driven element, the elements being mounted on mutually parallel axes of rotation and separated by an inter-axis distance, the orientation of the drive element being controlled depending on the orientation of the rotor shaft while the orientation of the driven element determines the orientation of the blade, one of the rotating elements comprising a finger (D) spaced apart from its axis of rotation and the other rotating element comprising a groove (C) which receives the finger and in which the finger can slide. Application notably to wind turbines, to marine turbines and to nautical and aircraft propellers.
