Patent number: 6995496Abstract: A method of extracting power includes coupling a transducer that converts mechanical power to electrical power to a disturbance; coupling an electrical circuit to the transducer such that a peak voltage experienced by the transducer is greater than two times higher than any peak voltage of an open circuit transducer due to the disturbance alone; extracting power from the transducer using the electrical circuit, and storing extracted power. Power is extracted from the transducer and applied to the transducer during different intervals in the course of the disturbance. A system for extracting power includes a transducer, an electrical circuit, and a storage element for storing extracted power.Type: GrantFiled: June 1, 2000Date of Patent: February 7, 2006Assignee: Continuum Photonics, Inc.Inventors: Nesbitt W.

Patent number: 6909224Abstract: A method of extracting electrical energy from mechanical motion includes reusing an elastic portion of energy in a transducer by transferring the elastic portion of energy to another transducer. An apparatus for extracting electrical energy from mechanical motion includes at least two transducers coupled such that an elastic portion of energy in one transducer is transferable to the other transducer. The transducers are coupled by a member defining a waved surface, and each transducer defines a coupler in contact with the waved surface for movement following the waved surface. Couplers of two transducers are positioned such that they move out-of-phase relative to each other. The transducers are bound to a plate positioned between members such that the plate is deformed. The plate and members are configured such that relative rotation therebetween produces a wave that travels along the plate.Type: GrantFiled: December 2, 2003Date of Patent: June 21, 2005Assignee: Continuum Photonics, Inc.Inventors: Kamyar Ghandi, Nesbitt W.
