  • Patent number: 10212571
    Abstract: Disclosed herein are a vehicle emergency notification method and apparatus using interaction with an external terminal. Some of functions of a conventional vehicle emergency notification apparatus are performed by a replaceable or detachable external terminal. The apparatus may provide notification of a vehicle emergency via interaction with the external terminal. The external terminal generates a Minimum Set of Data (MSD) related to an accident involving the vehicle. A proxy Public Safety Answering Point (PSAP) receives the MSD from the external terminal. The PSAP finally determines whether an accident involving the vehicle has occurred via interaction with a proxy PSAP FE and interaction with a vehicle occupant, and requests dispatch from an emergency agency if it is finally determined that the accident involving the vehicle has occurred.

  • Publication number: 20100085157
    Abstract: A method and an apparatus for providing a service using an RFID tag identifier in an RFID system are provided. The method includes: identifying the RFID tag for providing the service; acquiring an object identifier and a unique item identifier from the RFID tag and determining whether or not each of the identifiers can be interpreted; and disregarding the RFID tag if either of the identifiers cannot be interpreted, and determining whether or not the service should be provided according to validity of the tag identifier of the RFID tag if both of the identifiers can be interpreted. In addition, directly after interpreting the unique item identifier stored in the RFID tag, instead of providing information searches or service, an operation of determining whether or not the tag identifier of the RFID tag is used or issued by an RFID system is performed using the tag identifier stored in the RFID tag.
