    Abstract: A method for real time fire detecting and transmitting fire information is disclosed. The method includes monitoring whether the fire related value of an area which fire and fire prevention state need to be monitored is in the fire occurrence set value in the fire occurrence through at least one of CO2 sensor, temperature sensor, and image camera. When the fire related value is in the fire occurrence set value, an image camera rotates and shoots an image of the heaviest fire site and monitors the fire related value continuously. When the fire related value during fire is over the set range, the image camera rotates to the heaviest fire site from the present state and shoots an image of the heaviest fire site and, at the same time, monitors the fire related value by measuring CO2 information, temperature information, and smoke information.

  • Publication number: 20120322268
    Abstract: A method of forming a pattern includes forming a mask pattern on a substrate; etching the substrate by deep reactive ion etching (DRIE) and by using the mask pattern as an etch mask; partially removing the mask pattern to expose a portion of an upper surface of the substrate; and etching the exposed portion of the upper surface of the substrate. In the method, when a pattern is formed by DRIE, an upper portion of the pattern does not protrude or scarcely protrudes, and scallops of a sidewall of the pattern are smooth, and thus a conformal material layer may be easily formed on a surface of the pattern.

  • Publication number: 20120305224
    Abstract: A heat sink provided. In the heat sink in accordance with an embodiment of the present invention, a heat dissipation plate forms a channel between each of stages by isolating a plurality of heat dissipating fins in equal intervals and arranging the heat dissipating fins in a multi-stage circle shape. Then, the heat sink forms a path between the sequentially isolated heat dissipating fins at each of the stages. Also, a centrifugal fan alternatively blocks the channel and path at each of the stages through a rotation by a plurality of blades arranged in a multi-stage circle shape to be positioned between the channels. Then, the centrifugal fan is capable of inflowing outer air to discharge the air by generating a pressure difference of inter/outer air through a combination of the blade and the heat dissipation plate.
