Abstract: Disclosed is a core for a current transformer, which forms an upper core in a round shape, and is disposed at a position lower than the center of a power line having both ends of the upper core received, thereby minimizing the stress of a magnetic path, and increases the permeability, thereby enhancing the magnetic induction efficiency. The disclosed core for the current transformer includes an upper core curved in a semi-circular shape to have a receiving groove formed therein, and having both ends extended downwards to be disposed to be spaced apart from each other and a lower core disposed on the lower portion of the upper core, and having both ends extended upwards to be disposed to face both ends of the upper core.

Abstract: Proposed is a mask using an oxygen supply device. The mask includes a purification cartridge which purifies air for breathing, a mask part which introduces and discharges the air purified via the purification cartridge, a connector which fastens together the purification cartridge and the mask part, and an oxygen supply device which supplies oxygen through an oxygen hose connected to the connector.

Abstract: Disclosed are an apparatus and a method for preventing an accident of a vehicle using a sound prediction algorithm which is a neural network model generated by machine learning. The apparatus for preventing an accident of a vehicle may include an interface configured to receive, from a first microphone installed in the vehicle, ambient sound and a processor configured to predict a type of sound generated by an object from the ambient sound, determine a risk of accident between the vehicle and the object based on the type of sound and additional information of the sound, and control driving of the vehicle to allow the vehicle to avoid the object based on the determination that the risk of accident exists. The sound prediction algorithm may be stored in a memory in the apparatus for preventing an accident of a vehicle or provided through an AI server through a 5G network.

Abstract: Disclosed herein is a method of receiving driving data in platooning in an autonomous driving system. The method includes transmitting a platooning request message to a leader vehicle of a platoon in which a vehicle is to join, receiving a platooning response message as a response to the platooning request message, transmitting information of the driving data to the leader vehicle, and receiving a list of the driving data related to vehicles of the platoon from the leader vehicle, so that the platooning vehicle can receive driving data from another vehicle in a platoon. One or more of an autonomous vehicle, a user terminal and a server of the present disclosure can be associated with artificial intelligence modules, drones (unmanned aerial vehicles (UAVs)), robots, augmented reality (AR) devices, virtual reality (VR) devices, devices related to 5G service, etc.

Abstract: According to one embodiment of the present disclosure, an autonomous vehicle includes a loader which loads a service module, a driving unit which moves an autonomous vehicle, and a controller which controls the driving unit to perform at least one of acceleration driving, turning, and stopping of the autonomous vehicle, the controller checks a driving route of the autonomous vehicle and module information of a service module and controls the driving unit based on the driving route and the module information. At least one of the autonomous vehicle of the present disclosure may be linked to or integrated with an artificial intelligence module, a drone (an unmanned aerial vehicle, UAV), a robot, augmented reality (AR), virtual reality (VR), and a device related to 5G services.

Abstract: Disclosed is a medical tissue extraction instrument, which can allow an inspector to accurately locate a fine needle at a desired tissue extraction position without any need for assistance while assuring stable tissue extraction. The medical tissue extraction instrument includes a tissue extraction controller to control the pressure of a suction tube connected to a fine needle during extraction of tissue. The tissue extraction controller includes a suction pressure generator taking the form of a footboard and adapted to control a suction operation of the suction tube by being pushed downward.
