Abstract:
1. An electronically monitored, high-security, coder/decoder apparatus, comprising a key having a body and a mechanically produced code; a receiving body; a reader/operating unit arranged within the receiving body; and an electronic processing unit connected to the reader/operating unit, characterized in that the key ( 1 ) comprises at least one pressure value code generator/transmitter unit ( 12 ) having n pressure value elements ( 121 , 122 , . . . , 12 n ) for generating a code series, wherein said reader/operating unit ( 2 ) comprises a per se known pressure sensor/electric signal converter unit ( 22 ), an enabling unit ( 23 ) and an executing unit ( 24 ), the pressure sensor/electric signal converter unit ( 22 ) has an input ( 221 ) and an output ( 222 ), wherein the output ( 222 ) is connected to an input ( 331 ) of the electronic processing unit ( 3 ) that comprises a central control unit ( 31 ) and an interface ( 32 ), the output ( 231 ) of the enabling unit ( 23 ) is connected to the input of the executing unit ( 24 ), the input ( 232 ) of the enabling unit ( 23 ) is connected to the output ( 322 ) of the interface ( 32 ), an input/output line group ( 331 ) of the central control unit ( 31 ) is connected to the input/output line group ( 321 ) of the interface ( 32 ), the central control unit ( 31 ) comprises a second input ( 312 ) and the interface ( 32 ) has an optional input/output line group ( 323 ), and further that the central control unit ( 31 ) of the electronic processing unit ( 3 ) comprises a function analyzer ( 31 ) operating proportional to the pressure and associates a digital code value to the actual value of the output signal of the pressure sensor/electric signal converter unit ( 22 ), an adaptive unit ( 31 B), an intelligent code comparator ( 31 C), a storage unit ( 31 D), and an evaluating unit ( 31 E); wherein depending on the mode of use the adaptive unit ( 31 B), the intelligent code comparator ( 31 C), the storage unit ( 31 D) and the evaluating unit ( 31 E) can be placed in a location physically separate from that of the central control unit ( 31 ); the output (A 1 ) of the function analyzer ( 31 A) is connected to the input (B 1 ) of the adaptive unit ( 31 B) and one of the inputs (C 1 ) of the intelligent code comparator ( 31 C), the input (D 2 ) of the storage unit ( 31 D) is connected to the output (B 2 ) of the adaptive unit ( 31 B), the output (D 1 ) of the storage unit ( 31 D) is connected to the other input (C 2 ) of the intelligent code comparator ( 31 C), and the output (C 3 ) of the intelligent code comparator ( 31 C) is connected to the input (E 1 ) of the evaluating unit ( 31 E); and the input/output line group of the evaluating unit ( 31 E) functions simultaneously as the input/output line group ( 313 ) of the central control unit ( 31 ).
