Abstract: Proposed is a detachable lighting device including lighting units. The positions of the lighting units are changeable along a mounting rail within an interior space. The number of the lighting units and the mounting positions of the lighting units are adjustable. Accordingly, occupants within the interior space adjust light distribution as desired by each occupant.

Abstract: A cost-cognitive base station apparatus, a cost-cognitive user terminal, and a cost-cognitive network method, in which by recognizing costs based on network congestion, a user may select and receive appropriate network services, thereby reducing telecommunication expenses and inducing the user to a less congested network, which leads to improved network management efficiency.

Abstract: The present invention relates to smart glasses, and the smart glasses include: a frame mounted with lens; a pair of temples extended in one direction from both side ends of the frame so as to face each other; a rear camera mounted at an end of the temple and configured to photograph a rear image of a wearer; a display unit installed at one side of the lens and configured to display the rear image photographed by the rear camera; and a control device configured to control an operation of each of the constituent elements, thereby enabling a user to check a situation in the rear view without turning his/her head.

Abstract: An apparatus and a method for managing instant connection based on a wireless local area network are provided. The method includes: creating, by an accessed terminal, connection information required for setting connection therewith; creating, by the accessed terminal, a management frame by using the connection information; transmitting, by the accessed terminal, the created management frame to a peripheral terminal; receiving, by the peripheral terminal, the management frame and extracting connection information from the received management frame; and setting, by the peripheral terminal, connection with the accessed terminal by accessing the accessed terminal by using the extracted connection information to rapidly access a desired terminal without performing a device discovery process.

Abstract: Provided is a hyperlink display method based on a visit history accumulation, which is capable of providing search convenience between web documents by providing a self-updating hyperlink through accumulation of a visit history. The hyperlink display method includes displaying a plurality of hyperlink included in a web document when the web document is selected, recording a weight value of a selected hyperlink when any one of the plurality of hyperlinks is selected, and displaying the weight value of the selected hyperlink on the web document.

Abstract: Provided is a method of pairing terminals with each other, and a terminal for the method. The method includes sensing a physical motion of a terminal caused by a user and outputting a sensing value, comparing a reception value received from an external terminal with the sensing value, and establishing a communication path with the external terminal according to the comparison result.

Abstract: Provided are a method and apparatus for ensuring a cleaning robot to return to a charge station. The method includes the steps of: (a) measuring a battery usable time, a running speed, and an actual return distance of a cleaning robot during a cleaning operation; (b) calculating an allowable return distance on the basis of the battery usable time and the running speed; (c) comparing the actual return distance with the allowable return distance; and (d) returning the cleaning robot to the charge station when the actual return distance is larger than the allowable return distance as a result of the comparison. Therefore, it is possible to prevent the cleaning robot from being not returned to the charge station, thereby providing convenience to a user.

Abstract: Provided is a user interface apparatus that can control a telematics terminal safely and comfortably while driving, by recognizing a hand gesture image received through a camera in the telematics terminal as a corresponding control signal, and a method thereof. The interface apparatus using a hand gesture recognition, includes: an input receiving block for receiving a command registration request signal and a command selection signal; a hand gesture recognizing block for storing the hand gesture image in connection with a specific command, and transforming the hand gesture image into the corresponding command by recognizing the hand gesture image from the image obtained in the image obtaining block; and a command performing block for performing an operation corresponding to a command transformed in the hand gesture recognizing block.
