Abstract: A method, implemented by a computer, for determining a position of a personal mobility device (PMD) comprises: estimating a position of a PMD based on a first wireless signal; determining whether the PMD is within an intermediate area between a first area and a second area, based on an estimated position of the PMD; determining whether the PMD moves to the second area, by using both the first wireless signal and a second wireless signal; and determining position of the PMD by using any one of the first wireless signal and the second wireless signal based on a movement of the PMD to the second area.

Abstract: Disclosed is an antibacterial flexible cover window formed using an antibacterial coating composition containing antibacterial nanoparticles dispersed in a resin coating solution. In the antibacterial coating composition, 0.001 to 0.5 parts by weight of the antibacterial nanoparticles are dispersed in 100 parts by weight of the resin coating solution. The antibacterial flexible cover window includes an antibacterial layer that is formed by applying the antibacterial coating composition to a glass substrate. Therefore, the antibacterial flexible cover window exhibits a good and long-lasting antibacterial activity.

Abstract: A multi-robot control system and method. The multi-robot control method comprises the steps in which: a central control management server configures, into multiple groups, multiple robots to perform work at a site, and designates, as a leader robot, a certain robot included in each group; the central control management server calculates a work goal of each group on the basis of the entire work; and the central control management server transmits the calculated work goal of each group to the leader robot of each group so that the leader robot of each group distributes, to robots belonging to the corresponding group, detailed missions which the robots are required to perform on the basis of the calculated work goal of each group.

Abstract: The disclosed technology provides a game assistance system which allows a game helper to select audio data corresponding to game judgments and a game progress and allow the selected audio data to be output through a stadium speaker, and comprises: an information storage unit for storing game progress information; a signal receiving unit for receiving a game progress request signal from a game helper terminal; a control unit for selecting in the information storage unit the game progress information corresponding to the game progress request signal; and a signal transmission unit for transmitting the selected game progress information to the game helper terminal.
