Abstract: An actuator for optical image stabilization, includes a fixed frame having an internal space; a moving frame, accommodated in the internal space, configured to linearly and rotatably move on a plane perpendicular to an optical axis; a first ball member disposed between the fixed frame and the moving frame; a first driver, disposed on the moving frame and the fixed frame, configured to provide a driving force to the moving frame; a plurality of magnetic bodies disposed on the fixed frame to generate attractive force with respect to the first driver disposed on the moving frame; a sensor substrate having a portion coupled to the moving frame to be movable, together with the moving frame, and another portion coupled to the fixed frame; and an image sensor disposed on the portion of the sensor substrate.

Abstract: A cleaning apparatus including a vacuum cleaner and a docking station is provided. The cleaning apparatus includes a vacuum cleaner including a dust collecting chamber in which foreign substances are collected, and a docking station configured to be connected to the dust collecting chamber to remove the foreign substances collected in the dust collecting chamber. The dust collecting chamber is configured to collect foreign substances through centrifugation, and configured to be docked to the docking station, and the docking station includes a suction device configured to suction the foreign substances and air in the dust collecting chamber docked to the docking station.

Abstract: Charging system and method using a motor driving system are proposed. The charging system includes a battery, an inverter to which D.C. power stored in the battery is applied, including a plurality of legs each including two switching elements, a motor including a plurality of coils of which first ends are respectively connected to connection nodes of the switching elements of each of the plurality of legs, and second ends are connected to each other to form a neutral point, and an inverter driving part configured to control switching of the switching elements, so that switching speeds of the switching elements are different for each mode of a motor driving mode and a charging mode so as to change magnitude of charging voltage supplied to the neutral point of the motor and to output the charging voltage to the battery.

Abstract: The present invention provides a technique for preferring a season character by users by increasing a skill capability value of the season character in which a limitation capability value of a character is differentiated according to a time provided in a game compared with a general character in an online game managing the character.

Abstract: Provided is a technique which can increase user utilization of an item lottery service by providing users with an intuitive screen for the item lottery service, and, at the same time, a new source of fun.

Abstract: A method for providing a character in an online game includes, by a character provision apparatus, selecting at least one season character from a plurality of general characters previously provided in a game according to a preset season character selection criteria, generating at least one season character pool according to a period for which the season character is selected, and storing the selected season character in a corresponding season character pool, judging whether a status point limit adjustment item is provided, setting a status point limit of the at least one season character differently according to the period such that the status point limit of the at least one season character is higher than a status point limit of each general character acquired using the status point limit adjustment item, and displaying, on a user terminal, that the at least one season character is added to the game.
