  • Method of dividing coverage area for robot and device thereof
    Patent number: 7933686
    Abstract: A method of dividing a coverage area of a robot and a device for the same. That is, a method of producing a space map for a robot to work and dividing the space map into at least one segment and a device for the same. The method includes producing an occupancy grid map composed of grid points that are probabilistically distributed by sensing a distance from an obstacle, producing a configuration space map by increasing the thickness of an obstacle and a wall in the occupancy grid map on the basis of the radius and size of the robot, and dividing an area by sweeping the area with a band-typed slice in the configuration space map.

  • Illumination control apparatus using a pulsating waves
    Patent number: 7863826
    Abstract: An illumination control apparatus using a pulsating wave is disclosed, in which a pulsating power is supplied to an electric power supplied to a fluorescent light stabilizer which needs an AC voltage. The level of the same is varied and supplied to an illumination control, such as fluorescent light and common light, is possible based on an input power control of a stabilizer without changing an installation of a conventional fluorescent light and common light device and of the power construction. In addition, the electric power can be concurrently supplied to a plurality of stabilizers based on a capacity of apparatus without changing the construction of a conventional system.
