Abstract: A device having a light cavity includes, at one end, a plasmonic reflector having a grating surface for coupling incoming light into traverse plasmon waves and for coupling the traverse plasmon wave into broaden light, the surface serving to redistribute light within the cavity, the reflector being well suited for use in laser diodes for redistributing filamental cavity laser light into spatially broaden cavity laser light for translating multimodal laser light into unimodal laser light for improved reliability and uniform laser beam creation.

Abstract: A surface plasmon polaritron activated semiconductor device uses a surface plasmon wire that functions as an optical waveguide for fast communication of a signal and functions as a energy translator using a wire tip for translating the optical signal passing through the waveguide into plasmon-polaritron energy at a connection of the semiconductor device, such as a transistor, to activate the transistor for improved speed of communications and switching for preferred use in digital systems.

Abstract: The present invention provides a flywheel system with a variable speed synchronous reluctance motor-generator and a variable speed permanent magnet generator for providing backup power. The flywheel system incorporates rotating elements supported by electromagnetic bearings. Electric power provided by the backup generator maintains electromagnetic bearing operation during that portion of the coast down period when shaft speed falls below the minimum required for operation of the synchronous reluctance motor-generator.

Abstract: A method and system to automatically restart a permanent magnet turbogenerator/motor when a fatal fault is detected. The automatic restart logic includes time constraints and limitations on the number of iterations, and is useful regardless of whether the permanent magnet turbogenerator/motor is in a grid connect mode or a standalone mode, and regardless of how the fault originates or is detected. Additional control logic is utilized to handle grid transients and over load conditions to prevent a fatal fault from occurring by using time constraints and an iterative process, together with a brake resistor to control DC bus voltage.

Abstract: A method and system for connecting a plurality of power generators, each having an electrical power converter output and adjustable output voltage magnitude and frequency, with at least one digital communications bus to provide synchronization and load sharing. One of the plurality of power generators is designated a master unit and the remainder are designated as slave units.
