A system for transmitting a message for generating an Internet Protocol version 6 (IPv6) address is provided. The system includes at least one access terminal, an access point, and a router. The access terminal transmits a first medium access control (MAC) layer connection message including its own MAC address and a fast address setup indication field to the access point. The access point receives the first MAC layer connection message from the access terminal, and determines whether a duplicate MAC address of the MAC address of the access terminal exists in the same sub-network.

A key switch of a keyboard of the present invention includes a key cap and an elastic body which supports and allows the key cap to elastically move up and down. The elastic body is a band shaped structure and includes end portions which are pivotally supported above a substrate, a central portion bulged to contact a bottom surface of the key cap, and curved portions having a curvature opposite to that of the central portion disposed between corresponding ones of the end portions and the central portion. The curved portions of the elastic body are deformed at a position lower than an upper surface of the substrate. Therefore, the overall height of the key switch can be reduced, allowing for the manufacture of a slimmer keyboard unit.

According to example embodiments, a laser optical system includes a laser generator, at least one scan module, an objective lens, a relay lens, a review optical system, and a control device. The laser generator is configured to generate a laser beam. The at least one scan module is configured to reflect the laser beam generated by the laser generator and to direct the laser beam in different directions. The objective lens is configured to focus the laser beam on a substrate. The relay lens is configured to guide the laser beam scanned by the at least one scan module to within an incident range of the objective lens. The review optical system is configured to monitor, in real time, repair of the substrate using the laser beam. The control device is configured to control the at least one scan module.

Apparatus and method for selectively using a frame structure adequate for a system environment in a multihop relay wireless communication system are provided. The method includes generating a control signal including the frame information; and transmitting the control signal to a child Relay Station (RS). Accordingly, the frame structure adequate for the system environment can be used, and the transmission delay and the tradeoff between the overheads in each frame structure can be freely selected.

An apparatus and a method for sending a control information for retransmission in a multihop relay wireless communication system are provided. Data received from a lower node is checked for errors. The data is transmitted to an upper node, when the data has no errors. When two or more information, which include at least one of Acknowledgement (ACK) and Negative ACK (NACK) in response to a data reception are received from one or more lower nodes, the two or more information are transmitted to the upper node at the same time. Accordingly, the RS can transmit the control information for the ARQ provided from the lower nodes, to the upper node at the same time.

The present invention relates to an iris recognition device and method capable of improving iris recognition accuracy. To enhance iris recognition accuracy in consideration of variation in pupil size and iris region due to changes in intensity of lighting, the iris recognition device and method are configured to obtain multiple iris images having different iris sizes by capturing iris images of a person to be enrolled with a camera while adjusting brightness of lighting so that the iris size of the person to be enrolled varies from a maximum size to a minimum size, store the obtained iris images and associated iris size information for enrollment in a database interworking with the iris recognition device, and select enrolled iris images having an iris size most similar to that of an iris image captured by the camera for identification among many enrolled iris images for similarity measurement.
摘要:
When a defective pixel causing light leakage is detected in a flat display panel, an optical modulation region is formed in a substrate by emitting a laser beam such that a virtual image is displayed at a position corresponding to the defective pixel. Accordingly, quality of the flat display panel may be improved thereby increasing manufacturing process yield.
