Abstract: A life-saving robot includes a housing having a round ring shape, a buoyancy generator disposed at an upper portion of the housing, a thrust generator disposed at a lower portion of the housing and configured to provide propulsive force, a driver configured to provide power to the thrust generator, and a guard portion that is disposed at the lower portion of the housing and covers the thrust generator. An exterior of the life-saving robot is substantially spherical and defined by a combination of the buoyancy generator, the housing, and the guard portion.

Abstract: A positive electrode active material includes a nickel-based lithium composite metal oxide having a Ni content of 80 atm % or greater among transition metals except lithium, and in the form of a single particle or pseudo-single particle. The nickel-based lithium composite metal oxide has a coating layer positioned on the surface thereof, wherein the coating layer contains cobalt. The positive electrode active material also satisfies [Equation 1] 1?XY/Z?3, wherein X is the molar number (mol %) of Co in the coating layer based on 100 moles of the nickel-based lithium composite metal oxide, Y is the average particle diameter (?m) of nodules of the nickel-based lithium composite metal oxide, and Z is D50 (?m) of the positive electrode active material, wherein Z is from 5 ?m to 12 ?m.

Abstract: An apparatus for manufacturing a multi-pane glass unit is provided. The apparatus includes a first plate, a second plate, and a conveyor. The first plate is configured to hold a first glass pane. The second plate is configured to hold a second glass pane such that the second glass pane faces the first glass pane. The conveyer includes a first portion and a second portion. The first portion is configured to convey the first glass pane onto the first plate and the second portion configured to convey the second glass pane onto the second plate.

Abstract: A method and an apparatus for outputting body information of a user. The method of outputting the body information of a user comprises: designating coordinate points of the body information according to first, second, and third body information on a three-dimensional coordinate having the first, second, and third coordinates as coordinate axes; and outputting comparison information between the user body figure and the average body figure from the distance between the coordinate point of the body information of the average body figure designated on a three-dimensional coordinate in advance and the coordinate point of the body information of the user.
