Abstract

A self-powered fluid control apparatus includes a casing having an interior section defined by a plurality of walls, at least one louver positioned within the interior section and extending along a plane, and a fluid flow-driven electrical generator positioned within the interior section substantially along the plane, the fluid flow-driven electrical generator being configured to generate an output current when sufficiently driven by a fluid flow stream through the generator. The flow control apparatus also includes a motor coupled to the at least one louver and a controller configured to generate and provide the control signal to the motor, in which the motor and the controller are powered solely by the output current generated by the fluid flow-driven electrical generator.
