  • Patent number: 9843281
    Abstract: An output of a generator may vary according to the speed of the engine, physical characteristics of the engine, or other factors. A profile for a generator that describes a periodic fluctuation in an operating characteristic for the generator is identified. A field current of an alternator associated with the generator is modified based on the profile for the generator in order to counter variations in the output of the generator.

  • Patent number: 9780624
    Abstract: An assembly for harnessing a pendulum motion from fluid wave energy to convert to power. The assembly converts a fluid wave energy into electricity through a pendulum mechanism. The pendulum mechanism makes use of a buoyant sphere that floats in a fluid and absorbs wave energy, such as oscillations, vibrations, and disturbances known in wave energy, while floating in the fluid. A hemispherical pendulum swings in relation to the wave energy. The hemispherical pendulum transmits the swinging motion to an electrical generator for conversion to electricity. The harnessing of wave energy and swinging of the hemispherical pendulum is controlled through various components that balance and stabilize the assembly. The sphere comprises components to help control the irregularities from wave energy on the hemispherical pendulum through a directional guidance member, a velocity regulation member, and a stabilization member. A transmission cable transmits the electricity to a control center on shore.
