摘要:
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.

Provided is a control over access to a Device Management (DM) tree of a client. The client receives a secure area creation password from a server, creates a secure area by using the received creation password, and moves the DM tree to the secure area. In addition, the client receives a secure area access password from the server, accesses the secure area by using the received access password, and performs a remote management through a DM command received from the server. The authority to access the DM tree is given to only the client acquiring a password from the server, which effectively prevents an unauthorized change of a DM tree.

A method and system for encrypting data in a wireless communication system are provided. The system includes a first node for generating a first encryption key using a plurality of encryption key parameters when performing authentication with a second node, for changing a second parameter among the plurality of encryption key parameters to generate a second encryption key being identical to the first encryption key, if a first parameter among the plurality of encryption key parameters is changed during re-authentication between the first node and the second node, for generating the second encryption key using the changed first parameter and the changed second parameter, and for encrypting data to be transmitted to the second node using the second encryption key.

A portable communication apparatus is configured to perform a method for a power control of a Central Processing Unit (CPU) in a portable communication apparatus. The portable communication apparatus for a power control of the CPU includes a CPU for reporting an operation status of the CPU. The CPU is configured to change a power control level according to a control of an overhead determiner by using a pin and the overhead determiner for determining an overhead of the CPU by using the pin and for controlling the power control level of the CPU according to the overhead of the CPU.
摘要:
A device for managing a rights object and revoking a content object. The device includes a content/rights object storage unit for storing at least one content object, and a rights object corresponding to each content object. An authentication module performs mutual authentication between devices giving and taking a rights object, and when a revocation notification of a rights object among the stored rights object is received, authenticates whether an author having transferred the revocation notification is an author having a revocation right. A content object checking unit checks if the content object is valid before the content object is executed. A rights object management module searches for a rights object corresponding to a content object to be executed, and deletes a rights object corresponding to the revocation notification when the author is an author having the revocation right. A controller controls the modules and the units.
