Abstract:
An optical microscope system for sensing a nano-wire by using a polarizing plate and the Fast Fourier Transform method is provided to enable alignment between a nano-wire sample and a pattern by using an optical microscope. A light source unit(10) generates light and supplies it to a sample for nano-wire element. A rotary polarizing plate(20) is formed on a path of the light provided from the light source unit in order to polarize the light. An optical microscope(30) detects a nano-wire image by using the light polarized in the rotary polarizing plate and inputted into the sample. A CCD camera(31) is formed in one region of the optical microscope in order to photograph and store the nano-wire image detected the optical microscope. A data processing unit(50) performs the Fast Fourier Transform process for the stored nano-wire image through the CCD camera.
Abstract:
A repeater and a ranging method using the same in a mobile communication system are provided to prevent a loss of a ranging code and improve a call connection rate and the performance of periodical ranging. When a repeater transmits a message informing about initialization to a base station transmits a repeater initialization message to the repeater(S100). The repeater randomly selects an arbitrary ranging code among a plurality of ranging codes included in the message(S110) and transmits corresponding information to the base station(S120). The base station measures a timing offset and a power offset of the repeater by using the received ranging code and stores a result value(S130). The base station transmits the stored timing offset and power offset values included in a ranging code response message to the repeater(S140). The repeater stores the timing offset and power offset based on the values included in the received message(S150).
Abstract:
A method for managing a polling list in a mobile communication system and an apparatus thereof are provided to enhance resource efficiency while guaranteeing QoS by performing a polling procedure for a mobile terminal. A method for managing a polling list in a mobile communication system comprises the following several steps. An apparatus determines whether there exists an uplink resource allocation request from a mobile terminal(S610). In a case that there exists the uplink resource allocation request, the apparatus calculates a polling order among flows of plural mobile terminals which exist in an active list by using a QoS service flow parameter of the mobile terminals included in the active list of the polling list(S613). The apparatus adds flows of the mobile terminals at positions in the active list corresponding to the calculated polling order(S620). The apparatus allocates an uplink resource to the mobile terminal according to the order of the added active list(S630).

Abstract:
PURPOSE: A structure for a cantilever typed near field probe applicable to a head of an optical information storing device and a manufacturing method thereof are provided to maximally shorten an optical loss region on the head of the optical information storing device and improve an optical throughput needed for recording/playing the optical information more than a few thousands times of a current optical fiber probe. CONSTITUTION: A hole(11) penetrating an upper/lower part of a body is formed on a silicon substrate(10). A dielectrics thin film(20) is formed to a bottom of the silicon substrate as a mask layer. As an oxide film(40) is deposited to the upper part of the silicon substrate as the probe of a parabolic curve, an aperture(41) leading to the penetrating hole of the silicon substrate is formed on a vertex of the oxide film. As depositing on the oxide film, a near field aperture(71) leading to the aperture of the oxide film and having a high throughout is formed on a metal thin film(70).
