    摘要: Disclosed herein is a life saving system with an RFID tag having an IP communication function. The life saving system using RFID tags and a GPS comprises a plurality of RFID tags respectively attached to life jackets of survivors, respectively transmitting distress signals, and transmitting distress signals of other RFID tags when receiving the distress signals from the other RFID tags; smart points arranged in a distress area at predetermined intervals, including position information in the distress signals and transmitting the distress signals with the position information through satellite communication; and a control tower receiving the distress signals including the position information and transmitting a saving command.

    摘要: This invention relates to an inverted index storage structure that indexes keyword inputs into the storage space for the corresponding posting lists. In particular, the invention relates to the index structure that enables fast retrieval of the posting of the specific document from the posting list and enables efficient arrangement and maintenance of the posting list in document identifier (docID) order, so that fast addition, deletion, modification, and retrieval of documents are possible in environments where a database management system is tightly coupled with information retrieval. The technical solution is to store the posting list in a large object and map to each posting list a subindex that indexes the docID into the postings containing the docID.
