The object (operator's body) is fixed to the sensor 7 of the state of the object under study, and the inputs 31 and 32 of the device are given a sequence of pulses of frequency fi and / 2, and the generator 1 is turned on.

When pulses of frequency fi arrive at the counting input of trigger 22, the latter alternately transits into bullet and 1 dinar states. When the flip-flop 22 goes to one state, the control signal transfers the memory block 25 to the initial state and opens the key 3 through the delay element 23.

Operator 6 translates the binary number into octal and dials it on the dial pad 27. If the octal number is typed

correctly, the elements AND 28 blocks of one-bit binary numbers are closed. When the next impulse arrives at the input of the trigger 22, the latter goes to the zero position and the key 24 is opened. If the operator corrected the binary number in the eight. then one or more of the elements of AND unit 28, each one bit, is open and a pulse is recorded in a binary counter 29 ".

Simultaneously with the arrival of the first pulse of the frequency fo, an overflow pulse is generated, which translates the trigger

20 in a single state and through the device 19 enters the complement in the binary counter 18. At that, the key 2 opens and a random binary number enters the inputs of the decoder 4. A single signal at one of the outputs of the decoder 4 turns on the corresponding interference of the interference signal simulator 5. At the same time, the same unit impulse and a decoder 4 output translates through the HLI element
