Abstract: Disclosed are a power interruption method and a power interruption device based on a period measurement of an instantaneous power level. The present invention provides a power interruption method and a power interruption device which accurately determine, when a value measured by a current transformer (CT), a voltage detector, etc., is input into a main control unit, whether the measured value is a value equal to or more than a predetermined threshold during a digital analysis processing process to effectively protect a load which receives power by rapid and accurate power interruption for load-side instantaneous overcurrent or overcurrent caused by electric leakage/short-circuit.

Abstract: A method for transmitting packets by a transmitter in a wireless communication network and retransmitting the packets not received correctly by receivers is discussed. The method includes transmitting the packets to at least two receivers, receiving reception acknowledgement response signals including ACK or NACK signals for the packets transmitted to the receivers, analyzing patterns of the received reception acknowledgement response signals in accordance with a number of the ACK or NACK signals, differently index coding the packets which are not received correctly by each receiver, and retransmitting the index-coded packets.

Abstract: Provided is a method for retransmitting received data using index coding and statistical characteristics in a method for transmitting packets, by a transmitter, to at least two receivers in a wireless communication network and retransmitting packets which are not received correctly by each receiver, wherein the transmitter receives a reception acknowledgement response signal for the packets transmitted to the receiver and analyzes received patterns of the reception acknowledgement response signals transmitted from the receiver to differently perform index coding for each received pattern on the packets which are not received correctly by the receiver and retransmit the index-coded packets. According to the exemplary embodiment of the present invention, it is possible to effectively reduce a retransmission frequency of the packets which are not received correctly and a channel use frequency on communications and effectively use limited radio resources.

Abstract: A method of mounting a liquid crystal display module thereof which secures an upper sash including the liquid crystal display module to a lower sash in a notebook personal computer. An arm coupled to one end of a fixed rod by a hinge is arranged to be positioned between a side wall of the upper sash and a side wall of the lower sash. A screw goes through from the side wall of the upper sash, via the arm, to the side wall of the liquid crystal display module.

Abstract: A back light unit includes a lightguide (#204), a lamp (#202) fastened to one side of the lightguide, a U-shaped argentum reflector (#240) which encompasses the lamp, a reflecting sheet (#203) beneath the lightguide and a frame (#210) positioned under the reflecting sheet. The U-shaped argentum reflector and the reflecting sheet, as separate elements, are attached to form a continuous plane parallel to and along the length of the lightguide without resulting in a step arrangement at the connection. Additionally, the U-shaped reflector and the reflecting sheet are manufactured as separate elements each composed of the same or different materials.
