Abstract: A vertical take-off and landing flying car includes: power systems for both ground-traveling and flying in which, at upper portions of intermediate portions of central lines of wheel shafts of front wheels and rear wheels of a four-wheel electric car, motors are installed to be adjacent, parallel, and symmetrical to each other at left and right sides with respect to a central line of a chassis.

Abstract: A method of providing an on screen display (OSD) in a mobile communication terminal using a Q-camera includes: entering into a viewfinder mode, and receiving image data inputted from a camera sensor as image data of the viewfinder mode when an operation mode of the mobile communication terminal switches into a camera mode; if an OSD menu is set, merging an OSD image corresponding to a setting value of the OSD menu with the image data of the viewfinder mode, and then updating a display screen of the mobile communication terminal with the merged data; and encoding the image data of the viewfinder mode to perform the photographing if there is a request for photographing. The actually changed OSD image is selectively employed to merge with the image data of the viewfinder mode to update the display screen, and thereby a partial OSD function can be realized.

Abstract: An antenna system includes: an orthogonal multi-polarization antenna configured to output independent double orthogonal polarizations through two independent input/output terminals; an antenna main control unit configured to perform a polarization control algorithm, collect and analyze information for polarization control, and provide polarization control information; and a polarization control unit configured to perform independent amplitude and phase control with regard to a pair of independent channels connected to the orthogonal multi-polarization antenna, based on the polarization control information received from the antenna main control unit, so that various polarizations are formed.

Abstract: The present invention relates to a method of determining at least one traffic route in an MPLS (Multi-Protocol Label Switching) network.

Abstract: The present invention relates to a roaming method between a WLAN and a cellular network which can interwork the WLAN and the cellular network on the basis of a mobile IP system for smooth roaming.

Abstract: A point-to-multipoint traffic routing method that routes a multicast traffic through a determined tree on an MPLS network. A node on an MPLS network conducting a point-to-multipoint traffic routing method receives a message with an object including topology information on a determined tree, determines whether itself is a copy node or not based on the topology information, and copies, if determined to be a copy node, the received message to transmit to at least two nodes specified as next by the topology information. The present routing method ensures smooth operations of a copy and a merge node as well as an overall network.

Abstract: The present invention discloses an apparatus and method for deciding an access system based on WLAN signal strength in a WLAN/mobile phone network interworking system, and a mobile terminal therefor. The method for deciding the access system based on the WLAN signal strength in the WLAN/mobile phone network interworking system includes an initialization step for performing an initialization process on a WLAN driver module and a mobile phone network driver module, and measuring and displaying WLAN signal strength, a service decision step for selecting a WLAN service or mobile phone network service according to the measured WLAN signal strength, and a service access step for enabling the corresponding driver module to access the service decided in the service decision step.

Abstract: Disclosed is a method of providing an on screen display (OSD) in a mobile communication terminal using a Q-camera. The method comprises: entering into a viewfinder mode, and receiving image data inputted from a camera sensor as image data of the viewfinder mode when an operation mode of the mobile communication terminal switches into a camera mode; if an OSD menu is set, overwriting an OSD image corresponding to a setting value of the OSD menu with the image data of the viewfinder mode, and then updating a display screen of the mobile communication terminal with the overwritten data; and encoding the image data of the viewfinder mode to perform the photographing if there is a request for photographing. According to the method of this invention, only the actually changed OSD image is selectively employed to overwrite with the image data of the viewfinder mode to update the display screen, and thereby a partial OSD function can be realized.
