Transmitter-receiver system with (re-)initialization

摘要: A transmitter-receiver system (FIGS. 1 and 2), which checks the authorization to use an object (O), contains a transmitter (S), has transmitting element (SE) as well one or more operator control elements (SB), for their part can trigger of coded signals (SI), code concerning (O). The (S) at least single memory (SS) storage data on authorizations. receiver (E) receiving (EE), receives transmitted it, (ES) determining codes (SI) received, also logic circuit (μP), respectively received by means stored in and, depending result check actuates mechanism (ST). For (re-)initialization, preparation new future code/set random generator (Z), generates number (B) actuation (SB). transmits original (UC) without any dialog taking place automatically bidirectionally between (E).
