A method for detecting damage of a wind turbine blade of a wind turbine rotor having at least one wind turbine blade comprises: a light incident step of allowing light to enter an optical fiber sensor being mounted on each of the wind turbine blade and having a diffraction grating part having a refractive index which is periodically varied in a longitudinal direction of the diffraction grating part; a light detection step of detecting reflected light from the diffraction grating part; an obtaining step of obtaining, from a temporal change of a wavelength of the reflected light received in the light receiving step, a wavelength variation index representing a variation amount of the wavelength; and a damage determination step of determining presence or absence of a damage of the wind turbine blade on the basis of the wavelength variation index calculated in the obtaining step.

Method for detecting damage of wind turbine blade and wind turbine

An object is to provide a wind turbine blade having a serrated plate that can be formed irrespective of the overall structure of the blade, that is attached in the optimum shape, and that can effectively suppress noise occurring at a trailing edge thereof, and also to provide a wind power generator using such a wind turbine blade. Provided is a wind turbine blade () formed by bonding a back skin () and a front skin () and having a serrated plate () attached to a trailing edge () thereof, and the serrated plate () is formed so as to be attached by bonding the back skin () and the front skin ().

Wind turbine blade and wind power generator using the same

Provided are a wind turbine blade that can reduce the thickness of a turbulent-flow boundary layer generated on the blade surface of a blade tip portion to prevent noise generated at a trailing edge portion effectively, as well as a wind power generator using the same. Provided is a wind turbine blade, which is a wind turbine blade having an airfoil shape in cross section, wherein an angle-of-attack decreasing portion that decreases an angle of attack during rotation at at least a predetermined rotational speed is provided over a predetermined range from a blade tip to a blade root side.

There is provided automotive lamp peripheral parts excellent in heat resistance, rigidity and fogging property. The lamp peripheral part according to the invention is obtained from a resin composition containing 70% by mass or more of a polyphenylene ether (A) and a styrene-based resin (B), and has a haze value of a glass plate of 1.0% or less after the glass plate is subjected to a fogging test using an apparatus according to ISO 6452.

The present invention offers a method and system for checking the legality of a user who is subscribed in a telephone system, for example. When a user wants to access an information system operated by the host computer of said telephone system, e.g., a data-base, the legality of the user, whether he is really a person who is registered in the host side, is checked in the host side before a line is established between the user and the host computer. In detail, the host side modem first checks the user who is then checked by the host side modem and the processing unit of the host side computer. Thereafter, mutual communications, between the user and the computer, are allowed. The system, based on the invention, comprises a host side modem connectable to the processing unit of the host computer, and a user side modem connectable to said host side modem. Said host side modem can check user while said processing unit being capable to check user through the interaction with the host side modem.
