ELECTRONIC CODE LOCK Russian patent published in 2004 - IPC

FIELD: protection of objects against access of strangers.

SUBSTANCE: the electronic code lock (Fig.1) has input line 1, first unit 2 for reception of code, first comparison unit 3, counter 4 of the number of attempts of code selection, second unit 5 for code reception, second comparison unit 6, first code transducer 7, second code transducer 8, first storage unit 9, actuating unit 10, third comparison unit 11, fourth comparison unit 12, second storage unit 13, third storage unit 14. The input line is connected to the first inputs of units 2 and 5 for code reception, first group of outputs of unit 2 for code reception is connected to the first group of inputs of comparison unit 3, whose first output is connected to the first input of counter 4, the second output - to the input of actuating unit 10. The group of outputs of unit 5 for code reception is connected to the first group of inputs of comparison unit 6, whose output - to the group of inputs of code transducer 7 and to the group of inputs is connected to the group of outputs of counter 4, and the second group of inputs - to the group of outputs of storage unit 9, the group of outputs of code transducer 7 is connected to the second group of inputs of comparison unit 3. The second group of outputs of code reception unit 5 is connected to the first group of inputs of comparison unit 12, whose second group of inputs is connected to the group of outputs of storage unit 14. The output of comparison unit 11 is connected to the input of comparison unit 12, whose output is connected to the second input of counter 4, the group of outputs of storage unit 13 is connected to the first group of inputs of comparison unit 11, whose second group of inputs is connected to the group of outputs of code reception unit 5.

EFFECT: enhanced convenience of use and secrecy.
