摘要:
A turbine includes a plurality of blades that rotate in a single direction when exposed to fluid flow, wherein the plurality of blades are joined to the central shaft by a plurality of radial spokes disposed substantially perpendicular to the central shaft such that the rotating plurality of blades causes the shaft to rotate. The plurality of blades has a uniform airfoil-shaped cross section, where the airfoil cross section presents a non-zero angle of attack to the current. The plurality of blades wind in a spiral trajectory, rotating around the central shaft and having a variable radius along the length of the central shaft such that a distance measured from the plurality of blades to the center shaft is greater near the center of the turbine than at either end.

A submersible turbine-generator unit includes two or more turbines mounted on a common shaft with a generator therebetween. Each such turbine is capable of providing relatively low-speed, unidirectional rotation under a reversible ultra low head pressure and/or low velocity fluid flow. A plurality of airfoil-shaped turbine blades mount parallel to the common shaft and transversely to the direction of fluid flow for rotation in a plane parallel to the fluid flow. The turbines convert energy in the waterway currents into mechanical energy that will transfer through the turbine shaft to a cylindrical permanent magnet generator which will convert mechanical energy in the form of RPM and torque into electricity. Electricity from the variable speed electric generator is controlled, synchronized, conditioned and transformed into utility-grade electricity using a power electronics system in each module.

A submersible turbine-generator unit includes two or more turbines mounted on a common shaft with a generator therebetween. Each such turbine is capable of providing relatively low-speed, unidirectional rotation under a reversible ultra low head pressure and/or low velocity fluid flow.

A system is presented for controlling an interactive electronic plush toy using a macro computer program created on a mobile electronic device using a mobile application. The plush toy is provided with an electronic wireless network interface for communicating wirelessly with the smartphone via a network. The macro provides computer programming for instructing the plush toy to perform an Internet search query, receive results of the query, and perform predetermined actions based on the query results. The actions may include producing sound or motion to make the toy seem life-like.
摘要:
The present invention is directed to a turbine comprising a pair of opposing end discs concentrically aligned with a central axis of the turbine and a plurality of blades extending between the end discs. At least one end discs is adapted for engaging with a generator for generating power. The plurality of blades rotates in a single direction when exposed to fluid flow and thereby rotates the pair of opposing end discs. The plurality of blades are interconnected by at least one faired ring oriented parallel to the pair of opposing end discs and intersecting the plurality of blades, wherein the at least one faired ring is in concentric alignment with the central axis. The present invention further comprises a method for generating power comprising engaging the turbine with a generator to create a turbine generator unit and deploying the turbine generator unit within a fluid flow.
