  • Patent number: 6711897
    Abstract: An installation to apply ocean energy to power generation. The installation includes a floater, lever, chain, ratchet wheel, flywheel, generator, cable, etc. The floater and weight fixed to the floater move up and down with the motion of wave and drive the strength enlargement mechanism made up of a number of levers to travel alternately and pull the heavy flywheel to rotate constantly. The rotation of the flywheel enables the generator to run and yield electricity. The installation has simple structure and high efficiency and can easily increase or decrease the enlargement mechanism according to the capacity of generation. This installation with low cost can be widely utilized for pollution-free power generation in the coast.

  • Patent number: 6684174
    Abstract: A wind gauge apparatus and method. An illustrative embodiment includes a microphone positioned to engage wind pressure from a first relative direction and a controller coupled to receive an audio signal from the microphone. The controller compares the audio signal with plural threshold values, representative of wind pressure levels, and determines a first wind pressure level incident upon the microphone. Filtering and gain controls are used to condition the audio signal output from the microphone. Plural microphones are employed to allow that detection of wind direction and magnitude about a compass of directions. Digital signal processing is employed to process data. In an illustrative embodiment, the wind direction and magnitude data are used to recommend a golf club size adjustment and a golf swing direction adjustment to the user, who has taken a measurement of the wind with respect to a reference golf swing direction.

  • Publication number: 20030110767
    Abstract: The present invention concerns the method and installation to apply ocean energy to power generation. It is consisted of the floater, lever, chain, ratchet wheel, flywheel, generator, cable, etc. It is characterized by the fact that the float and weight fixed to it move up and down with the motion of wave, which drive the strength enlargement mechanism made up of a number of levers to travel alternately and pull the heavy flywheel to rotate constantly. By this way, the generator runs and yields electricity. The present invention has simple structure and high efficiency and can easily increase or decrease the enlargement mechanism according to the capacity of generation. This installation with low cost can be widely utilized for pollution-free power generation in the coast.
