Abstract: The invention concerns a method for providing a code input interface to a user by means of a twelve-keys arrangement consisted of three columns by four rows in a screen interactive device in which display on a screen changes and the user manipulates on the screen in accordance with the display of the screen.

Abstract: An objective of the invention is to eliminate the need of a frequent dust waste by the user and to provide efficient device for wasting the dust that has been collected in the robot cleaner. The invention provides a robot cleaner capable of discharging dust out to a dust discharge station, wherein the robot cleaner is capable of moving autonomously to collect dust, the robot cleaner comprising: a dust container for storing dust; a dust inlet for collecting dust into the dust container; and an opening and closing mechanism of the dust container, provided at a bottom surface of the robot cleaner, for discharging dust collected in the dust container.

Abstract: A mobile device-implemented method for providing a user of a mobile device having a touch screen a function to input a code into the mobile device among candidate codes, wherein the candidate codes are divided into a plurality of code series, the method comprising: (A) providing in the touch screen a first flick area, which is located in a ? side area at a side of a first lateral side of the touch screen, wherein each of the plurality of code series is associated with a corresponding flick action at the first flick area; (B) providing in the touch screen a second flick area, which is located in a ? side area at a side of a second lateral side of the touch screen; (C) detecting a first flick action at the first flick area to determine the code series; (D) detecting a second flick action at the second flick area. (G) determining a code to be inputted into the mobile device from a combination of the determined code series and the second flick action.
