    • A full bridge switching circuit includes a converter circuit including first and second converters. The first converter includes a first transformer and a first switching element part to control the first transformer in response to a first switching signal. The second converter includes a second transformer and a second switching element part to control the second transformer in response to a second switching signal. The first and second transformers are controlled by the first and second switching element parts to output first and second feedback signals, respectively. The full bridge switching circuit further includes a third switching element part having a third switching input connected to the first and second transformers, and an IC circuit to generate an OR signal by an OR operation of a first control signal generated from the first feedback signal and a second control signal generated from the second feedback signal.

    • The present invention relates to an LBS system in which user location information is obtained using a ULID code of RFID tags attached to various places such as a building, a store, road signs, footway and road, and various LBSs are provided based on the location information. The problems that can be caused when using a conventional GPS and a wireless network are solved. It is easy to immediately obtain location information through a tag and security of private information can be enhanced. The LBS system of the present invention of the present invention includes: a plurality of RFID tags distributed on various places, for wirelessly providing a ULID code of a location; an RFID reader for wirelessly receiving the ULID code from an adjacent RFID tag; a local ULID processor for extracting current location information through a wirelessly received ULID code; and a local LBS application for providing a user with an LBS on the basis of the extracted location information.
    • 本发明涉及一种LBS系统,其中使用附着在诸如建筑物,商店,路标,行人路和道路等各处的RFID标签的ULID代码获得用户位置信息,并且基于位置提供各种LBS 信息。 解决了使用常规GPS和无线网络时可能引起的问题。 通过标签立即获取位置信息是很容易的,可以增强私人信息的安全性。 本发明的本发明的LBS系统包括:分布在各地的多个RFID标签,用于无线地提供位置的ULID码; 用于从相邻RFID标签无线地接收ULID代码的RFID读取器; 本地ULID处理器,用于通过无线接收的ULID码提取当前位置信息; 以及本地LBS应用程序,用于基于提取的位置信息向用户提供LBS。
