Michael William Raftery has filed for patents to protect the following inventions. This listing includes patent applications that are pending as well as patents that have already been granted by the United States Patent and Trademark Office (USPTO).

  • Patent number: 8093736
    Abstract: A hydrokinetic device having a water surface float tethered to a submerged buoyant housing is provided with mechanisms for optimizing the amount of wave energy extracted from the waves by the device. Based on wave conditions, the optimization functionalities include controlling the depth of the housing to produce wave shoaling or storm avoidance, as well as to perform continuous phase control and load control for the purpose of matching the response frequency of the device to the frequency of the incident waves.
    Type: Grant

  • Publication number: 20080217921
    Abstract: A system for converting fluid surface wave energy into electrical energy. The system includes an electrical generating device, positioned in a waterproof housing, for producing electrical energy. A float, deployed on the fluid surface, is attached to the generating device when the housing is submerged within the fluid. Vertical motion of the surface waves produce vertical motion of the float, which turns and powers the electrical generating device. A plurality of anchors, positioned on the fluid floor, are attached to the housing so that the housing may be positioned proximate the fluid surface for creating a shoaling effect when a plurality of systems are deployed on the fluid surface.
