ELECTRONIC KEY Russian patent published in 2005 - IPC

FIELD: means for protecting different structures against intrusion.

SUBSTANCE: electronic key comprises connector 1, remote circuit protective unit 2, interface unit 3 and control unit 4 linked to memory unit 5. Three input groups and input-output group of memory unit 5 are correspondingly connected to three input groups and input-output group of control unit 4. Input, the first output and the second output of control unit 4 are connected correspondingly with the first output, the first and the second inputs of interface unit 3. The first output of protective unit 2 is linked with input of memory unit 5. The first, the second inputs and the second output thereof are linked correspondingly with the second, the third outputs and the third input of interface unit 3. The third, the forth inputs and the third, the forth outputs are linked correspondingly with the first and the second outputs and the first and the second inputs of connector 1.

EFFECT: simplified scheme, increased reliability and improved protection of remote key circuits against static electricity discharge.
