Abstract: A thermoelectric module includes: an electrode; a double layer stacked on a thermoelectric pellet; and a solder layer interposed between the double layer and the electrode to bond the double layer to the electrode, the solder layer containing a Sn—Cu-based alloy. The solder layer is formed to have an interface with one of the double layer and the electrode and has at least one ? layer having an ? phase (Cu3Sn).

Abstract: Disclosed herein are an object recognition apparatus of an automated driving system using error removal based on object classification and a method using the same. The object recognition method is configured to train a multi-object classification model based on deep learning using training data including a data set corresponding to a noise class, into which a false-positive object is classified, among classes classified by the types of objects, to acquire a point cloud and image data respectively using a LiDAR sensor and a camera provided in an autonomous vehicle, to extract a crop image, corresponding to at least one object recognized based on the point cloud, from the image data and input the same to the multi-object classification model, and to remove a false-positive object classified into the noise class, among the at least one object, by the multi-object classification model.

Abstract: A gas turbine apparatus may include one or more driving shafts; a compressor configured to receive power from the one or more driving shafts, suck air, and compress the sucked air at high pressure. The gas turbine may include a combustor configured to mix the compressed air with fuel, and combust the fuel mixture to generate combustion gas. A turbine is connected to the one or more driving shafts and is configured to rotate while the combustion gas passes through the turbine. The turbine may include one or more first turbine blades configured to rotate in a first direction and one or more second turbine blades configured to rotate in a second direction opposite to the first direction. The one or more first turbine blades and the one or more second turbine blades may be alternately arranged along an axial direction of the turbine.

Abstract: An outdoor broadband unit receives a current time, a short term maintenance mode time period, and a long term maintenance mode time period from a remote network device. The outdoor broadband unit determines a mode associated with selection of an antenna beam, provided on an antenna of the outdoor broadband unit, based on at least one of the current time, the short term maintenance mode time period, and the long term maintenance mode time period. The outdoor broadband unit selects an antenna beam to use based on the determined mode.

Abstract: An apparatus and a method for searching a transmission signal from a neighboring base station acquires a location of present cell through initial cell searching, sets an operation mode according to whether or not rough location information of neighboring cell is provided by the present cell, sets a mask window based on time information of the cell which is already known, searches the section of mask window and remaining sections selectively according to the operation mode, and acquires precise time information of neighboring cells using energy peak searched from the selected section. In this manner the neighboring cells can be searched rapidly and easily by adding the window masking function to the initial cell searching apparatus.

Abstract: The present invention is related to a mobile telecommunication system, and more specifically, to a multi-peak detector of the mobile telecommunication system and a method thereof for high-speed acquisition of paths necessary for a timing synchronism using a hardware multi-peak detector. The peak detector according to the present invention can include a circuit that cumulatively saves a plurality of energy values that have been calculated through a matched filter and a squarer, and a circuit that outputs several energy values out of the cumulatively saved plural energy values, which are saved based on a high-ranked enable control signal and a high-ranked mask signal.

Abstract: The present invention relates to an apparatus for synchronizing frame and detecting code group/number that is useful for an initial cell search of an asynchronous IMT-2000 system. To this end, the present invention discloses a method for synchronizing frame and detecting code group/number, including the steps of: synchronizing a slot at the time of a system booting, wherein the system obtains time offsets by using at least two despreaders with different timings from each other; detecting energies and time offsets based on the designated position of the slot timing; and detecting frame synchronization and code group/number by using the detected energies and information.
