PROGRAMMABLE TRANSPONDER

摘要

A control system comprises an interrogation unit (IU) and at least one transponder (T) and includes means for transmitting data from the interrogation unit to the transponder in order to transfer a new applications program or new applications program routine into the program memory (33) of a microprocessor (32) of the transponder. The function of the transponder does not therefore have to be predetermined during its manufacture, but can be selected or altered subsequently. An electrostatic coupling arrangement is preferably provided for the transfer of data at least in one direction between the interrogation unit and the transponder.
