Abstract:
PURPOSE: A direction control device for a camera is provided to adjust the direction of a camera two-dimensionally using a one-dimensional driving device. CONSTITUTION: A direction control device for a camera comprises a connection bar unit(110), a ball joint unit(112), a 4-bar unit(100), and a one-dimensional motor. One end of the connection bar unit is connected to a spot on the backside of a camera, which corresponds to the center of a lens. The ball joint unit includes a linear motion guide for guiding three-dimensional rotational and linear motions to the connection bar unit. The 4-bar unit comprises first through third straight links and one triangle link, wherein a first vertex(P) of the triangle link is connected through a ball joint to the other end of the connection bar unit. The first straight link is a fixed link whose one end is connected to a rotary shaft(A). The second straight link is connected between a second vertex(B) of the triangle link and the rotary shaft. The third straight link is connected between a third vertex(C) of the triangle link and the other end(D) of the first straight link. The one-dimensional motor provides torque for the second straight link through the rotary shaft.

PURPOSE: A method and a system for diagnosing disability are provided to diagnose disability based on recording information by utilizing a database for developmental disabilities using a database structure. CONSTITUTION: An information collection unit(610) collect information by observing developmental disabilities. An information extraction unit(620) selects a sentence by analyzing the collected information on the basis of natural language. The information extraction unit performs a morphological analysis process by performing the natural language process. A group generation unit(630) generates a group by extracting a correlation index for the selected word or the selected sentence. A disability diagnosis unit(640) classifies the disabilities for the developmental disabilities on the basis of the group and generates the diagnosed results.

Abstract:
PURPOSE: A refuge guidance robot apparatus is provided to enable efficient lifesaving by enabling rescuers to rapidly grasp information on gas concentration of a fire site. CONSTITUTION: A refuge guidance robot apparatus comprises a main body, a sensor module(110), a movable module(120), a camera module(130), a wireless communication module(140), a movement direction detecting sensor(150), a lighting module(160), and a control module(170). The sensor module comprises one or more sensors(113,114) for sensing environmental information. The camera module takes a photograph of the structure region surrounding the image. The wireless communication module transmits and receives data, image, and voice signal to an external device of a remote site. The movement direction detecting sensor senses the traveling direction of the robot.
Abstract:
PURPOSE: A lookup table based single positive dual negative rule fuzzy controller and a control method are provided to shorten a calculation time by obtaining each member function value from a search table. CONSTITUTION: An address generator(110) generates a lookup table address corresponding to a fuzzy controller input by using a fuzzy controller input, a common reference function, and a member function for a fuzzy set. A member function value output unit(120) outputs a member function value corresponding to a search table address from the search table storing the member function value corresponding to the fuzzy controller input. A corrector(130) corrects the member function value according to the fuzzy controller input, and outputs the corrected member function value.
