Abstract: The present invention relates to a system and method for three-dimensional advertising. The system and method of the present invention store advertisement data capable of being rendered as a three-dimensional object, the real position of which is designated. When a mobile communication terminal including a GPS receiver measures its own position, and transmits the position information of the mobile communication terminal to an advertisement server, an advertisement server transmits advertisement data set around the position information of the mobile communication terminal to the mobile communication terminal. The mobile communication terminal renders the advertisement data into a three-dimensional object, and displays the rendered advertisement data by overlapping same with a real image, which is displayed through a camera built in the mobile communication terminal.

Abstract: The subject of the invention is a weak-field magnetic sensor with the following features: etched circuit coils are substituted for conventional coil technology. The sensor includes an amorphous core having epoxy bases stacked relative to one another on the top and bottom surfaces thereof. One epoxy base has a coil Y etched thereon. A second epoxy base has a coil X etched thereon. The remaining epoxy base has circular patterns etched thereon. The amorphous core is formed from at least two amorphous thin boards stacked on opposite sides of an epoxy base thin board. The epoxy base thin board has a particular pattern etched thereon and the capacity for vertical conductivity. The coil conductor size and position accuracy is controlled in increments of microns by the etching process. The range of detection errors and the level of reception has no non-uniformities. A thin and small sensor in terms of the structure is therefore enabled.
