| 20090028387 | Apparatus and method for recognizing position of mobile robot - Provided is an apparatus for recognizing the position of a mobile robot. The apparatus includes an image capturing unit which is loaded into a mobile robot and captures an image; an illuminance determining unit which determines illuminance at a position where an image is to be captured; a light-emitting unit which emits light toward the position; a light-emitting control unit which controls the light-emitting unit according to the determined illuminance; a driving control unit which controls the speed of the mobile robot according to the determined illuminance; and a position recognizing unit which recognizes the position of the mobile robot by comparing a pre-stored image to the captured image. | 01-29-2009 |
| 20090157227 | Apparatus, method, and medium for sensing slip in mobile robot - An apparatus, method, and medium for sensing a slip in a mobile robot is provided. The apparatus for sensing a slip in a mobile robot includes a driving motor control unit to control a driving motor that rotates a plurality of driving wheels of the mobile robot, a first rotation sensor to sense a first rotation angle of the mobile robot by using the difference between traveling distances of the plurality of driving wheels, a second rotation sensor to sense a second rotation angle of the mobile robot by sensing a rotation of the mobile robot, and a slip-sensing unit to sense the slip of the mobile robot by comparing the first rotation angle with the second rotation angle. The driving motor control unit controls the driving motor to travel straight in a specified pattern. | 06-18-2009 |
| 20100085692 | Electronic device case and method for manufacturing the same - Disclosed are an electronic device case provided with a touch sensor unit having an improved adherence structure and a method for manufacturing the same.

| 20100174409 | Robot slip detection apparatus and method - A technique of detecting a slip of a robot using a particle filter and feature information of a ceiling image is disclosed. A first position of the robot is computed using a plurality of particles, a second position of the robot is computed using the feature information of the ceiling image, and whether a slip has occurred is determined based on a distance between the first position and the second position. | 07-08-2010 |
| 20100217439 | Map building apparatus and method - Disclosed are a map building apparatus and method using a distance measurement. According to an aspect, by creating a first map and a second map respectively using the characteristics of different characteristic areas based on a distance-voltage characteristics of a distance measurement sensor, and combining the first map with the second map, a grid map is created. Accordingly, since a map regarding a peripheral environment is created using plural areas of the distance-voltage characteristics, a more accurate map may be created. | 08-26-2010 |

| 20080309574 | SYSTEM AND METHOD FOR PREVENTING COPYING OF ELECTRONIC COMPONENT DESIGNS - Techniques are provided to prevent undesired and/or unauthorized analysis and access to electronic components designs. A shield can be utilized to prevent invasive and/or non-invasive analysis methods such as the use of x-rays to determine the structural configuration and/or component makeup of an embedded antenna. In addition, a damageable material that can be utilized alone or in conjunction with the shield is also provided. When attempting to access the antenna and/or components included therein, any inappropriate force or exposure to certain elements, such as heat, will cause the material and the antenna and/or the components therein to be damaged or melted beyond a point of useful recognition for the entity. Furthermore, thin films can be utilized to construct one or more portions of the antenna to the same effect. In addition, the antenna and/or components can be configured for actively reconfiguring a resonant frequency of the antenna. | 12-18-2008 |
| 20090171575 | NAVIGATION APPARATUS AND METHOD FOR PROVIDING TURN-BY-TURN POSITION LIST - The present invention relates to a navigation apparatus and a method for providing a user with a list of turn-by-turn positions (TBTs) located ahead on a route. The navigation apparatus of the present invention according to an embodiment comprises a GPS receiving module for receiving navigation satellite signals and calculating a position; a controller for receiving position information from the GPS receiving module, outputting the position information together with map information, and controlling operation of the GPS receiving module; and a storage unit for storing the map information, wherein the controller displays information on two or more TBTs on a proceeding route in the form of a list, the list having a size determined depending on distances to the TBTs included in the TBT information. According to the present invention, there are advantages in that a user can easily recognize information on TBTs ahead and drive a vehicle along a set route only with a TBT list. | 07-02-2009 |
| 20090171576 | NAVIGATION APPARATUS AND METHOD OF PROVIDING INFORMATION ON POINTS OF INTEREST - An apparatus of providing map information, which includes a Global Positioning System (GPS) receiving module configured to calculate positional information with respect to the apparatus, a display configured to display map information and the calculated positional information, and a controller configured to search for Points of Interests (POIs) from a selected POI category, and to control the display to display image icons representing POIs that were found during the search on corresponding positions within the displayed map information. | 07-02-2009 |
