Abstract: A video decoding method for predicting a picture, which is split into equal-sized coding tree blocks, in units of blocks, the method includes: reconstructing a block vector for a current coding block in a current coding tree block to be decoded, by decoding block vector information from a bitstream, wherein the current coding block is one of blocks split from the current coding tree block in a tree structure; and setting, as a prediction block of the current coding block, a reference block indicated by the block vector in the picture in which the current coding block is located.

Abstract: An autonomous driving safety system for sharing a risk-based operation design domain includes an autonomous driving system configured to control a vehicle driving unit according to information detected by a sensor unit to perform autonomous driving, in which the autonomous driving system includes an operation design domain update unit configured to evaluate a risk of at least one of a static operation design domain and a dynamic operation design domain recognized by the sensor unit while driving to update the operation design domain.

Abstract: Disclosed is a method of manufacturing bamboo toothbrush and a toothbrush manufactured thereby. According to the method of manufacturing bamboo toothbrush of a detailed embodiment of the present invention and a toothbrush manufactured by the method, it is possible to improve strength, surface roughness, and moisture resistance of a bamboo and adjust the color of the bamboo using hot pressing. Further, since sanding and polishing and separate coating and drying are not performed, the process time is reduced, whereby the manufacturing cost can be reduced.

Abstract: The present invention relates to a particle transfer system and a particle transfer method which allow preciously-weighed particles to smoothly pass through a vertically-provided vertical pipe of a transfer line when powder-type particles are transferred along the transfer line, and which prevent the particles from remaining or stagnating in the vertical pipe.

Abstract: A cylindrical secondary battery includes: an electrode assembly including a first electrode plate and a second electrode plate; a cylindrical case having a disk-shaped top portion and a side portion extending from the top portion, the cylindrical case accommodating the electrode assembly; a cathode terminal extending through the top portion and insulated therefrom; a first current collector plate electrically connected to the first electrode plate and the cathode terminal; a second current collector plate electrically connected to the second electrode plate and the side portion of the cylindrical case; a cap plate coupled to the side portion and insulated therefrom; and an insulation tape between the top portion of the cylindrical case and the first current collector plate and covering the first current collector plate.

Abstract: An embodiment of the present invention relates to a cylindrical secondary battery in which a positive electrode terminal is adhered and fixed to a cylindrical can by an insulating sheet, and thus sealing between the cylindrical can and the positive electrode terminal can be facilitated due to an increased contact area.

Abstract: The present invention relates to an address generating device of a remote smart meter reading system, and a method therefor, the device including: a first MAC address generation unit expressing, in four bits, respective numbers of a meter ID of a watt-hour meter, and then converting the numbers into hexadecimal numbers so as to generate a first MAC address of 48 bits; a second MAC address generation unit generating a second MAC address of 64 bits by adding bits to the first MAC address; a first IP address generation unit expressing, in four bits, the respective numbers, and then converting the numbers into the hexadecimal numbers and adding bits thereto so as to generate a first IP address of 64 bits being used as an interface ID of IPv6; and a second IP address generation unit generating a second IP address using the second MAC address as the interface ID.
