Abstract: The present invention relates to an apparatus and method for capturing an image of a welding spot during a welding task and determining an accurate position of the welding spot based on the captured image in order to perform an accurate welding task. A beam splitter splits a path of light reflected from a welding section of a spacer grid from a path of a laser beam generated from a laser generator. An image sensor receives light reflected from a welding spot of the spacer grid, and senses and stores an image of the spacer grid. Welding control means controls the image sensor to capture the image of the spacer grid, receives the image of the spacer grind from the image sensor, calculates an accurate position of the welding spot based on the received image, corrects position information of the welding spot based on the calculated position, and controls a servo motor so that the laser generator can accurately collimate the welding spot based on the corrected position value.

Abstract: The present invention relates to a method and apparatus of an idle state of a mobile terminal. One embodiment relates to a method and apparatus that display message in an idle state of a mobile terminal. Another embodiment relates to a method and apparatus for driving an application for an idle state in a mobile terminal. A further embodiment relates to a method and apparatus for providing idle state contents to a mobile terminal.

Abstract: Disclosed therein is a multi-axis laser welding head for a spacer grid, which is one of essential components of a nuclear fuel assembly. More particularly, the multi-axis laser welding head for the spacer grid can be operated more smoothly and variously during the welding of the spacer grid to thereby weld the spacer grid more exactly and precisely. For this, the multi-axis laser welding head includes a welding head having a movement within a predetermined angle like the back and forth swing of the pendulum, and can irradiate a laser beam in various directions by having additional axis in comparison with the prior art.

Abstract: A method and apparatus for providing an idle screen service are disclosed. A mobile communication terminal receiving contents provided from at least one content provider server in a mobile communication system environment is also disclosed. The mobile communication terminal may include a content receiver module which receives contents provided through a mobile communication system by separating into layers, a handset operating system module which operates the terminal and runs an application and which has a user interface, and a content management application module which synthesizes the contents separated into layers received from the content receiver module into one idle screen layer and which provides it to the idle screen of the mobile communication terminal.

Abstract: Disclosed is a spine massager including a massaging member configured to move vertically along with horizontal reciprocating movements, thereby providing an enhanced massaging therapy effect.
