Abstract: A moving robot and a control method thereof according to the present invention create a cleaning map including information on a travelable area of a cleaning area based on obstacle information, create a create a manufactured user map by changing forms and outlines by area with respect to a plurality of area configuring the cleaning map, and create a user map having a form similar to that of the cleaning are in a real indoor space by changing a form and an outline of a map including information on the travelable area according to an arear, so that a user easily recognizes a position of each area to input a cleaning command through the map, and a cleaning command with respect to an area which the moving robot cannot run is prevented from being input. Since the moving robot does not unnecessarily move an area, operation power consumption is reduced. The moving robot may run a cleaning area with limited power to efficiently clean the cleaning area.

Abstract: A mobile robot system and a related control method sets a virtual wall as a specific area so that a mobile robot cannot approach within a cleaning area to restrict a traveling of the mobile robot, registers the virtual wall on a map when the virtual wall for restrict the approach of the mobile robot is set by a terminal, calculates a location of the virtual wall for the cleaning area to avoid the virtual wall, and restricts the approach of the mobile robot by matching the virtual wall to the cleaning area, controlling the mobile robot as if an actual physical obstacle exists by setting the virtual wall on the map through the terminal and matching to an actual cleaning area, and achieving an easy cleaning setting and effectively controlling the mobile robot as it can be plurally set at a desired location irrespective of the number.

Abstract: Disclosed are a moving robot and a controlling method thereof. The moving robot which selectively moves an area based on a stored map to search a charging station within a short time when there is a need for charging due to consumption of a battery. Although a position of the moving robot is optionally changed, the moving robot recognizes a position thereof so that it is easy to move between areas and an influence according to complexity of an obstacle is reduced. Since the charging station in an area may be searched through small moving by setting a specific point in the area as a search position to search the charging station, stop of an operation during searching the charging station may be solved and the charging station may be exactly searched within a short time.

Abstract: A transmission and reception method and apparatus for reducing a PAPR in an orthogonal frequency division multiplexing (OFDM) system are provided.

Abstract: An electric product to communicate with a terminal includes: a wireless communication unit equipped in the electric product; a firmware storage unit storing a firmware file for update received from the terminal; a firmware modulation and confirmation unit determining whether the firmware file for update received from the terminal is error free; and a firmware update execution unit executing an update of firmware received from the terminal, wherein while the electric product is registered to the terminal, the electric product receives the firmware file for update from the terminal.

Abstract: A method and system of processing an invalid click is provided. The method includes the steps of: verifying an invalid click Internet Protocol (IP) address of a user terminal generating the invalid click with respect to an advertisement; associating the invalid click IP address with the advertisement, and registering and maintaining the invalid click IP address in an invalid click list when the invalid click IP address is verified; and providing the user terminal of the invalid click IP address with a result page other than the advertisement with respect to an advertisement exposure request using the invalid click IP address. When a number of clicks is greater than or equal to a predetermined number of clicks with respect to the same advertisement using the same IP address over a predetermined time, the step of verifying verifies the same IP address as the invalid click IP address.

Abstract: A method and system of inspecting advertising contents of a keyword advertisement is provided. The method includes: crawling a Universal Resource Locator (URL) registered by an advertiser and extracting a URL keyword related to an advertisement site of the advertiser; extracting a target keyword from a plurality of advertisement information being registered in relation to the URL; and determining further inspection-required advertisement information through keyword comparison between the extracted URL keyword and the target keyword, the further inspection-required advertisement information having low relevance to the advertisement site.

Abstract: A method of providing a keyword advertisement and a system for executing the method are provided. The method of providing the keyword advertisement includes: generating and maintaining an advertiser history ranking by using an advertiser keyword purchase history; and ordering the keyword advertisement display with respect to a user keyword by using the advertiser history ranking.
