The present invention provides a maintenance system for wind turbine equipment. The maintenance system includes a trolley support unit (130), a trolley (140), a pulley, a winch unit (150) and a door (160). The trolley support unit is provided in the nacelle so as to be movable in the longitudinal direction of the nacelle. The trolley is provided on the trolley support unit so as to be movable in the lateral direction of the nacelle. The pulley is rotatably installed in the trolley. The winch unit is connected to the pulley through a wire. The door is provided in the nacelle so that an element of the nacelle to be repaired is removed from or inserted into the nacelle through the door. Therefore, in the present invention, when maintenance or repair of an element in the nacelle is required, it can be conveniently conducted without using a separate crane.
Abstract:
The present invention relates to a system and a method for providing a service to an end-point terminal in a CPNS environment, and to a CPNS server, a mobile communication terminal and an end-point terminal for the same. The system comprises a CPNS server which performs an authentication procedure based on received terminal information about the mobile communication terminal and requests a content providing server to execute the CPNS mobile communication terminal for opening a CPNS session with the end-point terminal when the CPNS server provides the CPNS; and the end-point terminal requests the CPNS reservation from the mobile communication terminal or the CPNS server and executes the CPNS provided by the CPNS server via the mobile communication terminal.
Abstract:
The present invention relates to a billing system, method, a service server and end-point terminal respectively which allows the end-point terminal to use billing authentication information of another mobile communication terminal. The billing system comprises: a first mobile communication terminal and at least a second mobile communication terminal with each mobile communication terminal connected in common to a service server through a mobile communication network in which said end-point terminal is connected to said first mobile communication terminal through a first short-range communication network for providing contents to the first end-point terminal that uses the billing authentication information of the second mobile communication terminal and a billing server for performing a billing process if the service server transmits contents to the first end-point terminal upon validation by the service server by comparing the billing authentication information transmitted from the first end-point terminal with billing authentication information received from the second mobile communication terminal to determine if a match exists.
Abstract:
The present invention relates to a contents providing system and method for providing data services through a short-range wireless communication network, and a CPNS server and a mobile communication terminal for the same. The contents providing system includes the CPNS server, the mobile communication terminal and an end-point terminal. When the end-point terminal is initially connected to the mobile communication terminal through the short-range wireless communication network, the CPNS server registers information on the end-point terminal as connection history information by matching the end-point terminal information to a corresponding mobile communication terminal. The CPNS server provides response information if either an end-point terminal information request or a contents information request is received from the mobile communication terminal. The mobile communication terminal is connected to at least any one of a plurality of adjacent end-point terminals through the short-range wireless communication network. If a contents transfer request key signal is received while a mobile WEB or WAP service is used, the mobile communication terminal transmits corresponding contents that are played back when the contents transfer request key signal is received to the end-point terminal. The end-point terminal transmits and receives information to and from the mobile communication terminal through the short-range wireless communication network. Therefore, the present invention is effective in that an end-point terminal that does not have a communication function can be provided with specific contents requested by a user while a mobile WEB or WAP service is used on a mobile communication terminal.
Abstract:
A liquid crystal display (LCD) device maintains a cell gap and prevents press defects via the use of ball spacers. The liquid crystal display device includes first and second substrates facing each other, a plurality of first spacers, a plurality of second spacers, and a liquid crystal layer filled between the first and second substrates. The first spacers are formed between the first and second substrates at portions of a black matrix layer of the second substrate. The first spacers include a plurality of first balls with a first diameter and a first solid to aggregate the first balls. The second spacers are formed at portions of the black matrix layer between the first and second substrates. The second spacers include a plurality of second balls with a second diameter 0.2 to 0.6 μm smaller than the first diameter and a second solid to aggregate the second balls.
Abstract:
In a method of forming fine patterns, a photocurable coating layer is formed on a substrate. A first surface of a template makes contact with the photocurable coating layer. The first surface of the template includes at least two first patterns having a first dispersion degree of sizes, and at least one portion of the first surface of the template includes a photo attenuation member. A light is irradiated onto the photocurable coating layer through the template to form a cured coating layer including second patterns having a second dispersion degree of sizes. The second patterns are generated from the first patterns and the second dispersion degree is less than the first dispersion degree. The template is separate from the cured coating layer. A size dispersion degree of the patterns used in a nanoimprint lithography process may be adjusted by the light attenuation member, so that the fine patterns may be formed to have an improved size dispersion degree.
