20130204483 | ROBOT CLEANER - A robot cleaner is provided. The robot cleaner may include a casing including a moving device, an image input disposed in the casing, the image input including a plurality of light emitting parts that emits light toward an obstacle and an image sensor that acquires a 3D image of the obstacle onto which the light is emitted by the plurality of light emitting parts, and a main controller that extracts 3D data with respect to the obstacle from the 3D image of the obstacle acquired by the image input to control the moving device. | 08-08-2013 |
20130338831 | ROBOT CLEANER AND CONTROLLING METHOD OF THE SAME - A robot cleaner is provided. The robot cleaner may precisely detect a peripheral obstacle using a particular optical pattern. An asymmetric cross-shaped optical pattern may be irradiated, and a pattern image with respect to the optical pattern-irradiated region may be analyzed to determine whether or not an obstacle is in the moving path, and a width or a height of the obstacle. Further, the robot cleaner may perform operations such as a forward motion, a backward motion, a stopping motion and a detour motion, based the obstacle detection result. | 12-19-2013 |
20150115876 | MOBILE ROBOT, CHARGING APPARATUS FOR THE MOBILE ROBOT, AND MOBILE ROBOT SYSTEM - A charging apparatus is configured to charge a mobile robot. The mobile robot is configured to emit an optical pattern. The charging apparatus includes a main body configured to perform charging of the mobile robot as the mobile robot docks with the charging apparatus, and two or more position markers located at the main body and spaced apart from each other. The position markers are configured to create indications distinguishable from a surrounding region when the optical pattern is emitted to surfaces of the position markers. | 04-30-2015 |
20150120056 | MOBILE ROBOT - Disclosed is a mobile robot including a main body and a pattern irradiation unit emitting a cross-shaped optical pattern including a horizontal line optical pattern and a vertical line optical pattern intersecting the horizontal line optical pattern. The pattern irradiation unit includes a light source and a lens converting light emitted from the light source into the cross-shaped optical pattern, the lens includes convex cells on an incidence surface upon which the emitted light is incident, the incidence surface is divided into a first area converting the light emitted from the light source into the horizontal line optical pattern and a second area converting the light emitted from the light source into the vertical line optical pattern, vertical convex cells extended in parallel in the vertical direction are formed in the first area, and horizontal convex cells extended in parallel in the horizontal direction are formed in the second area. | 04-30-2015 |
20150157182 | MOBILE ROBOT AND OPERATING METHOD THEREOF - Data within a designated distance from a main body of the mobile robot is accumulated and stored to form a local area map. A traveling direction or a rotating direction is set while avoiding an obstacle around the main body and a path may be readily set. Repetition of unnecessary operation is prevented and thus a traveling velocity based on rapid movement may be improved. Obstacles are readily avoided and cleaning efficiency may be improved. | 06-11-2015 |

20090079914 | LIQUID CRYSTAL DISPLAY PANEL - A liquid crystal display (LCD) panel, comprising an array substrate and a color filter substrate, the array substrate comprises a first substrate, shielding bars, gate lines, data lines, and pixel electrodes, the color filter substrate comprises a second substrate, wherein the array substrate and color filter substrate are divided into at least a left side region and a right side region; a plurality of first BMs are provided on the second substrate in the left side region of the color filter substrate, with respect to a central line of the data line corresponding to each of the first BMs, a length of a right side portion is longer than that of a left side portion for each of the first BMs; a plurality of second BMs are provided on the second substrate in the right side region of the color filter substrate, with respect to a central line of the data line corresponding to each of the second BMs, a length of a left side portion is longer than that of a right side portion for each of the second BMs. In the LCD panel of the present invention, the length of a side of the BM on the second substrate in different regions of the color filter substrate is increased to increase the critical dimension, so that the occurrence of light leakage can be effectively avoided when the LCD panel is flapped. | 03-26-2009 |
20090253332 | ASSEMBLING METHOD OF LIQUID CRYSTAL DISPLAY PANEL - Disclosed is an assembling method of LCD panel comprising the following steps. In step one, a plurality of spherical spacers are mixed with a liquid crystal solution so as to form a mixed liquid crystal solution with spherical spacers dispersed uniformly in the liquid crystal solution. In step two, a seal agent is applied onto edge portions of a first substrate and the mixed liquid crystal solution is applied onto a second substrate by dropping. In step three, the first and second substrates are assembled, spreading the mixed liquid crystal solution therebetween so as to dispose the spherical spacers uniformly between the first and second substrates. | 10-08-2009 |
20150253605 | LIQUID CRYSTAL DISPLAY PANEL - The present disclosure provides a liquid crystal display panel. The liquid crystal display panel comprises an array substrate and a color filter substrate. Liquid crystal is filled between the array substrate and the color filter substrate, the array substrate includes a pixel electrode, and the color filter substrate includes a common electrode corresponding to the pixel electrode. The common electrode stores charges when an external object carrying static electricity touches a display region of the liquid crystal display panel, and thus a potential difference is formed between the pixel electrode of the array substrate and respective touch points, contacting with the external object, in the display region of the liquid crystal display panel, so that the liquid crystal between the touch point and the pixel electrode is deflected according to the formed potential difference. With such liquid crystal display panel, a process for displaying dynamically depicted graphs is simplified. | 09-10-2015 |
