Abstract: Provided is a holographic microscope including an input optical system configured to emit polarized input beam, a first beam splitter configured to emit an object beam by reflecting a portion of the polarized input beam, and emit a reference beam by transmitting a remaining portion of the polarized input beam, a reference optical system configured to separate the reference beam into a first reference beam and a second reference beam, a camera configured to receive the first reference beam and the second reference beam and the object beam that is reflected by an inspection object, the camera including a micro polarizer array, wherein a first polarization axis of the first reference beam is perpendicular to a second polarization axis of the second reference beam.

Abstract: An apparatus for compressing a joint between an electrode tab extending from an electrode assembly and electrode lead includes an upper pressing unit, a lower pressing unit, a suction unit, and a driving unit for moving the upper and lower pressing units up and down. The apparatus includes an air injection nozzle that injects air obliquely from an exterior region of an upper compressing member toward the joining surface of the electrode tab and electrode lead.

Abstract: Provided is a 360-degree image encoding apparatus and method, and a recording medium for performing the same function. The 360-degree image encoding apparatus divides an input image to be encoded into a plurality of regions in a vertical direction and encodes the divided regions while changing resolutions thereof so that all regions have the same resolution to maintain pixel continuity among the regions when a predictive image is generated and the regions have resolutions changed according to the degree of distortion of the regions when a residue image is encoded.

Abstract: The rectangular gate vacuum valve assembly comprises a gate frame having an inner space defined therein, wherein the gate frame has opposite side walls and opposite top and bottom walls, wherein the gate frame has opposite first and second gates defined in the opposite side walls respectively, wherein the gate frame has first and second holes defined in one of the top and bottoms walls, wherein the first and second holes are spaced from each other, wherein the other of the top and bottoms walls is entirely blocked; a first valve mechanism configured to translate through the first hole in the inner space and/or to rotate in the inner space to selectively open or close the first gate; and a second valve mechanism configured to translate through the second hole in the inner space and/or to rotate in the inner space to selectively open or close the second gate.

Abstract: A method of selecting a base transceiver system (or sector) in an area where signals from various base transceiver systems (or sectors) are superimposed. In order to be suitable for a system that aims at the packet transmission such as the high data rate (HDR) communication system, the load information of the base transceiver system (or sector) is transmitted to the mobile station. The mobile station selects the optimum base transceiver system (or sector) according to the load information, and requests the down-link data transmission to the base transceiver system at the desired data transmission rate.
