Abstract:
An active transponder of an identification system comprises a memory for storing coded information and supplying it to a transmitter output, and data means independent of the memory for supplying further information to the output. The transponder has a battery and the data means can comprise detectors which detect when the voltage of the battery falls below respective predetermined levels. The data means can also comprise input connections arranged to receive signals representing the updated values of respective parameters. These signals are supplied to respective inputs of a data selector independently of the memory.
