Abstract: A method for granting access to restricted areas such as computers, doors, vehicles, or other areas to which access by a user is controlled. An access code is transmitted from a central computer via radio waves to a user's radio terminal, such as a mobile telephone. The radio terminal transmits the access code over a short-range radio link to a communication device at the restricted area. The communication device transmits the access code to the central computer, which compares the received code with the code that the computer transmitted to the radio terminal to determine whether access should be granted.

Abstract: A method of determining the position of a transponder in relation to a communicator, wherein the transponder (9) can be read by a communicator (11) which is adapted to send an inquiry signal to the transponder, wherein the transponder (9) is adapted to answer the inquiry signal and therewith transfer information from a memory in the transponder and wherein the communicator (11) is connected to a principal data system (16) and is adapted to receive the information. The method is characterized by connecting the communicator (11) to an envelope detector (15) which is caused to detect the envelope of the signal received from the transponder (9); and by determining the relative position between the transponder (9) and the communicator (11) from the envelope.

Abstract: An identification device comprising a transponder (2) that can be read by means of a transmitter/receiver unit (11) arranged to transmit an enquiry signal (13) to the transponder, where the transponder is arranged to reflect (14) the enquiry signal and in this way to modulate the enquiry signal with information stored in a memory in the transponder and where the transmitter/receiver unit (11) is arranged to receive the modulated enquiry signal, which transponder (2) is integrated into a mobile telephone (8) and which transponder (2) is connected to a source (6) of power. The invention is characterised in that the said source (6) of power is constituted by the source of power of the mobile telephone used to power the clock of the mobile telephone (8).

Abstract: A method and apparatus pertaining to identification systems in which a transponder reflects an inquiry signal from a communicator. The reflected signal is modulated with data that can be read by the communicator, and the data-carrying modulation includes a check sum calculated on the basis of data stored in the transponder memory. The transponder check sum is stored permanently in the transponder memory. A calculated check sum is calculated in the communicator based upon the transponder data included in the reflected inquiry signal, and the calculated check sum is compared with the check sum stored in the transponder to determine whether the transponder identifies an authorized person or object that is to be identified.

Abstract: A seal for sealing goods in goods containers, such as freight containers, freight cars, trucks, and the like. The seal interacts with a door or other hatch that can be opened in order to seal it against unauthorized opening. The seal is activated when the goods container is loaded and is broken when the goods in the goods container are unloaded. The seal includes a transponder that includes a memory and that communicates with a communicator for the reading of information stored in the transponder memory. The seal is placed into an active mode during the sealing operation, and information as to the time when the seal is opened is stored in the transponder memory. The opening time information is subsequently read by the communicator.

Abstract: A method of transmitting geographically governed information to automotive vehicles or to individuals, based upon the location of the vehicles or individuals. The exact or approximate position of the vehicle or the individual is determined in relation to permanently spaced units for radio communication between those units and a vehicle-carried or an individual-carried communications unit. A computer and associated database contains information that includes different data relevant to different geographical areas. The computer sends relevant information to a receiving unit in each and every one of those vehicles or individuals whose position has been determined, and in accordance with the geographical area in which the vehicle or the individual is located.

Abstract: A method for carrying out payment of a vehicle toll for travel within a zone subject to a toll. The vehicle is equipped with a transponder that can be read by a transmitter/receiver unit that transmits a query signal to the transponder. The transponder replies to the query signal and transfers information from a memory in the transponder to the transmitter/receiver unit, which is located at a boundary of the toll zone. The transmitter/receiver unit is connected to a supervisory computer system that debits the owner of the transponder when it is read. When the computer system has received information that a transponder has been read, the computer system sends an SMS message to the mobile telephone of the owner of the transponder, and/or an e-mail message to the mobile telephone of the owner or to a computer that is possessed by the owner.

Abstract: The present invention relates to method and means for a system initiated subscriber information redistribution in order to achieve a load redistribution within a pool of core network nodes. The subscribers, that are affected by the redistribution, are determined by the bit values in their TMSI's. These specific TMSI's are then arranged to be treated as invalid by the cellular system. Messages etc. from subscribers with invalid TMSI's will be “trapped” in the cellular system and the subscriber information that belongs to these subscribers will be redistributed to new core network nodes.
