Abstract
An identification device (1) for a pneumatic spring (2) includes an RFID transponder (8), which is completely embedded into the elastomer matrix (13) of the flexible member (4). An electromagnetic field is generated by a read device (9), wherein the energy necessary for supplying the RFID transponder (8) is taken from the electromagnetic field generated by the read device (9). When the read device (9) is active, information can be exchanged between the RFID transponder (8) and the read device (9). The RFID transponder (8) operates completely without an internal energy supply. The RFID transponder (8) may also be configured as a read/write transponder including a memory chip, wherein data may be stored on the memory chip in a safe and permanent manner. By retrieving data from the RFID transponder (8), an identification of the pneumatic spring (2) is possible even without any internal power supply of the RFID transponder.

7. A method for making a flexible member comprising the steps of:
-
constructing a flexible member blank from at least one reinforcement carrier layer and at least one non-vulcanized elastomer material; introducing an RFID transponder into said elastomer material so as to cause said RFID transponder to be completely embedded in said non-vulcanized elastomer material, wherein the RFID transponder has at least one unit configured to draw energy necessary to supply the RFID transponder from electromagnetic field generated by a read unit and, when energy is available to the RFID transponder, information can be exchanged between the RFID transponder and the read unit; and
, vulcanizing the flexible member. - View Dependent Claims (8)
