Abstract: A fuel cell system includes a fuel cell stack and a battery that are connected to a high voltage line in parallel, a converter connected to the high voltage line and the battery while being located therebetween and configured to control a voltage at the high voltage line, and a controller, in a stop control mode of the fuel cell stack, when an error occurs in a drop control of an output voltage of the fuel cell stack, the controller dropping the voltage at the high voltage line under the output voltage of the fuel cell stack by the converter to drop the output voltage of the fuel cell stack.

Abstract: A display device includes first pixel and second electrodes spaced apart from each other on a substrate, an inorganic insulating layer on the substrate and partially covering the first pixel electrode and the second pixel electrode, residual patterns disposed between the first or second pixel electrodes and the inorganic insulating layer, a bank structure on the inorganic insulating layer with first and second openings defined therethrough to overlap the first and second pixel electrodes, first and second light emitting layers on the first and second pixel electrodes, first and second common electrodes on the first and second light emitting layers, and first and second inorganic layers on the first and second common electrodes in the first and second openings. The bank structure includes first and second bank layers including different metal materials, and the second bank layer includes tips protruding to a center of the first or second opening.

Abstract: The object of the present invention is to provide an improved fence jumping detection rod that solves the problem in regard to erroneous alarms caused by unspecified external factors such as approaching animals, strong winds, or the like, and that is capable of quickly restoring to the original state after detection of a fence jumping. To achieve the object, the fence jumping detection rod according to the present invention includes: a support rod having a support portion for supporting a mesh or a line, and a shaft coupling portion extending to the one side of the support portion; a shaft support coupled to the shaft coupling portion via a joint shaft to enable the support rod to move in an arc-like motion; an elastically supported ball allowing the support rod to move in an arc-like motion only when a torque greater than a torque set about the joint shaft is imposed on the shaft coupling portion; and a sensing means for sensing an arc-like motion of the support rod.

Abstract: The present invention relates to an intrusion sensing net of a structure that does not allow the sensing net to be disassembled or dissolved easily but does enable easy installation at the site, and to a weaving machine that weaves the same. The invention relates to an intrusion sensing net the entirety whereof is woven with one sensing line, that includes a repeating and consistent weaving pattern; wherein the consistent weaving pattern comprises a support line, a line of a zigzag shape that enables the support line to connect all the vertices of one side starting from one end of the support line and ending at the other end, and another line of a zigzag shape that is formed in symmetry with the zigzag shape based on the another support line, wherein at the point where the line of a zigzag shape meets with the another line of a zigzag shape, two sensing lines corresponding to each line wind and hold one another.
