Abstract: The present invention relates to an image information decoding method. The decoding method includes receiving a bit stream including a Network Abstraction Layer (NAL) unit that includes information related to encoded image, and parsing a NAL unit header of the NAL unit. The NAL unit header may not include 1 bit flag information that represents whether a picture is a non-reference picture or a reference picture in the entire bit stream during encoding.

Abstract: Disclosed herein are a video decoding method and apparatus and a video encoding method and apparatus. In video encoding and decoding, multiple partition blocks are generated by splitting a target block. A prediction mode is derived for at least a part of the multiple partition blocks, among the multiple partition blocks, and prediction is performed on the multiple partition blocks based on the derived prediction mode. When prediction is performed on the partition blocks, information related to the target block may be used, and information related to an additional partition block, which is predicted prior to the partition block, may be used.

Abstract: Disclosed are a robot and a method for delivering articles by the robot. A robot, according to an embodiment of the present disclosure, includes: one or more loading spaces configured to load articles; a travel driver configured to move the robot; an input interface configured to obtain identification information of the articles; a measurer configured to measure temperature of each of the articles; a temperature regulator configured to heat or cool the loading spaces; and a controller configured to determine a type of each of the articles from the identification information, determine a delivery route based on the determined type of article, and control the temperature regulator based on the measured temperature while controlling the travel driver such that the robot moves along the determined delivery route. Examples of the present disclosure are implemented by executing a machine learning algorithm in a 5G environment connected for Internet of things (IoT).

Abstract: A full-duplex communication method in a high efficiency wireless local area network (WLAN), the full-duplex communication method being performed by an access point (AP) in a WLAN network, includes transmitting a reference frame to at least one station (STA); receiving an uplink frame from the at least one STA in a time period determined on the basis of the reference frame; and transmitting a downlink frame to the at least one STA in a specific time duration of the time period, wherein the uplink frame and the downlink frame are transmitted through the same channel.

Abstract: A full-duplex communication method in a target wake time (TWT) service period of a high-efficiency wireless local area network (WLAN) is performed by a TWT responding station, and includes transmitting TWT schedule information to at least one TWT requesting station; transmitting information regarding a resource unit (RU) to the at least one TWT requesting station through a reference frame in a TWT service period (SP); receiving an uplink frame from the TWT requesting station in a time period determined on the basis of the reference frame through the RU; and transmitting a downlink frame to the TWT requesting station in a specific time duration of the time period. The uplink frame and the downlink frame are transmitted through the same channel.

Abstract: A vacuum type pickup apparatus may include an absorption pad having an absorption inlet for contacting and/or picking up an object. A pad holder may be connected to the absorption pad. The pad holder may also have a vacuum line. A separator may be provided in the pad holder for forcibly releasing the object from the absorption inlet of the absorption pad. During the forcible release of the object, the air around the absorption pad may be drawn into the pad holder, thus reducing or preventing the potential contamination by impurities of the object as well as the equipment around the object. Also, an additional vacuum extinguisher may not be required, thus simplifying the structure of the vacuum type pickup apparatus and reducing installation costs. Furthermore, the object may be picked up and released in a relatively expedient, safe, and accurate manner, despite the suction force of the vacuum that may be maintained in the pad holder.

Abstract: Example embodiments of the present invention include a socket for testing a semiconductor package. The socket comprises a body having a through hole. A lower magnet is disposed in a lower region of the through hole, and a first type magnetic pole of the lower magnet is directed upward. An upper magnet is disposed in an upper region of the through hole, wherein the first type magnetic pole of the upper magnet is directed toward the lower magnet. The upper and lower magnets are structured to absorb a shock wave which is generated when the semiconductor package is arranged for testing. A conductive medium is disposed between the lower magnet and the upper magnet to electrically couple contactors of the semiconductor package to a base substrate of the socket.
