  • Publication number: 20110001988
    Abstract: An apparatus for measuring a thickness, which includes: a first beam splitter for reflecting or transmitting a ray irradiated from an optical source or a ray reflected by a measurement object; a first lens part which condenses a ray to the measurement object and generates a reference ray having a difference of a light path in comparison with a ray reflected by the measurement object; a second lens part for condensing a ray to the object to be measured; an interference light detector which corresponds to at the first lens part so as to form a light path and detects an interference signal generated by the ray reflected by the measurement object and the reference ray; a spectroscopic detector which corresponds to the second lens part so as to form a light path different from the light path formed by the interference light detector and splits the ray reflected by the measurement object so as to detect an intensity and a wavelength of each split ray; and a light path converter for selectively transmitting a ray to

  • Publication number: 20100149326
    Abstract: A plasma monitoring device includes a plasma supplier including a power supply, a reaction gas supply line, and an emission nozzle for emitting plasma, which is generated therein, toward an object; a camera unit for obtaining an image of the plasma emission state; and a controller for obtaining a measurement value by converting pixel information of the image into a numerical value and comparing it with a reference value, which is a measurement value in a normal emission state, to check the plasma emission state. The camera unit obtains an image of the plasma emission state, and the controller analyzes the image to obtain a measurement value, which is used to monitor the state of plasma in real time and control the amount of reaction gas supplied to the plasma supplier and the plasma discharge condition, so that plasma is evenly emitted from the plasma supplier.

  • Publication number: 20100008487
    Abstract: An apparatus and a method for blocking a specific network in a mobile communication terminal are provided. The method includes adding a first network to a blocked network list, when the first network is the only network available to provide service to a terminal, temporarily removing the first network from the blocked network list and temporarily receiving service from the first network. Thus, the user does not have to pay roaming fees in the unwanted network, suffer from undesired communication quality, or use unwanted additional functions.
