  • Patent number: 10355557
    Abstract: The invention discloses an ocean current power generator disposed in the ocean. The ocean current power generator includes two power generators, a foil floating member and a control unit. Each of the power generators includes an impeller, and the ocean current drives the impellers to rotate to generate electricity. The foil floating member is connected to the two power generators, and the foil floating member includes a front body and a rear body. The control unit is configured to control the amount of sea water in the front body or the rear body, so as to adjust the center of gravity of the foil floating member.

  • Patent number: 9661442
    Abstract: The invention discloses a method for transmitting digital contents between devices. First digital contents are modulated into an audio signal in a first device, wherein the first digital contents include contact information and at least one index of at least one second digital content. The audio signal is outputted by at least one audio generator of the first device and then received by at least one audio receiver of a second device. The audio signal is demodulated in the second device to make the second device obtain the first digital contents. The second device obtains the at least one second digital content according to the at least one index of the at least one second digital contents through a wired or wireless communication.

  • Publication number: 20170051725
    Abstract: A method for diagnosing blades of a wind turbine is provided. The method includes steps of acquiring, via a microphone, an operation sound of the wind turbine when the wind turbine is under operation; transforming the operation sound into a time-frequency spectrum; integrating the time-frequency spectrum over time to generate a marginal spectrum; determining whether any blade of the wind turbine is damaged according to the marginal spectrum and a reference curve.
