  • Automatic resynchronization of transmitter in the event of corrupted memory
    Patent number: 5646996
    Abstract: Loss of synchronization between transmitter and receiver of a remote entry system is detected during the communication sequence between transmitter and receiver, by generating a checksum of the authentication code at the initiation of the communication sequence and comparing it with a checksum previously stored. If the checksums do not match an automatic resynchronization sequence is begun in which random numbers are generated by the transmitter and broadcast to the receiver for subsequent use as rolling code or linear feedback shift register variables.
