(circuit case) of the device, and the output KOMna viTopa 44 is connected to the counting input i of the binary counter 48, the R input of which is the third input 26 of unit 6, the outputs of the counter 48 are connected to the G inputs 49 of the register 50, the input of the recording sync of which is nl The second input 24 of block 6, and the outputs of register 50 are connected to a digital-to-digital converter (1 (, ILP) 51, the output of which is - .i..jiCH by the output of block 6, First 4, and switch II, as well as

The switches 20, 27 and 43 switch manually from the front panel of the device to which the slots of variable resistors 34 and 36 and the lamp A2 are also inserted.

The device works as follows.

By assignments that will analyze the signal frequency (let them be nf numbers), the switches of the first switch 4 are set to the position where the output 3 of unit 2 commutes with the input 7 of unit 6, and its output 5 with the first output 8 of the first switch (block 9 input)

By assignments, by which the amplitude of the signal will be analyzed (let them be PD numbers), the switches of the first switch 4 are set to the position where the output 3 of unit 2 switches to the output 8 of the first switch (input of block 9) by the indications the indication is an increase in the parameter over a certain band, the switch 43 is set to the Out position, and the variable resistors 34 and 36 are brought to the minimum resistance position.

On leads, which are characterized by the reduction of the signal to the size of the band, the switch 43 is set to In position, and the variable resistors

ry 34 and 36 outputs to the maximum resistance position.

The device operates in three modes: preparation, sleep and sleep with selective deprivation.

The initial mode is always em-, with a preparation mode. EEG sensors; EM1, BDG are connected to the patient. All switches of the second switch 11 are set to switch the input 12 of the switch 11 with the output, and thus the absence of current through the control winding 15 of the relay 16, resulting in the preparation mode regardless of the behavior of the EEG, EMG, BDG signals photofrequency torus 18, but the bell 21 does not work.

Switch 27 is pressed and released, as a result of which all the triggers 41 of block 9 are reset to 0 and the display element 42 does not light up.

The signals of EMG, EEG, BDG are amplified in block 1 of amplifiers, smoothed

in block 2 and come from leads with numbers n through input 3 to output 8 of switch 4 and to input of block 9, and from leads with numbers from city through input 3 to output 7 of switch 4 and to input of block 6, and from the output of block 6 through the second input of switch 4 to output 8 and to the input of block 9.

The input 24 of block 6 receives pulses with a frequency F, and the input 26 of the block receives the same pulses, which detain the register 50 at the time it is running. Thus, during

Therefore, the inputs of block 9 are supplied with EEG, EMG, BDG signals from the leads with the numbers Пд, proportional to the frequency of the signal of the leads with the numbers p.

The purpose of the preparation mode is to set the thresholds U + and U-, corresponding to the moment of arrival of the selected sleep phase using variable resistors 34 and 36. The doctor visually records the fact that the signature (amplitude or frequency) reaches a characteristic value and at this moment turns the resistors 34 and 36 to light corresponding lamp 42. Such an operation is performed for all the leads involved.

When switching to sleep mode, switch 20 opens, blocking bell 21, and switches of the second switch I1 are set to connect input 10 (block 9 output) to AND-NOT element inputs 14. When the amplitude and frequency of signals previously set in preparation mode are reached clockwork, triggers 41 analyzers are installed

in I, at the output of the element AND-NOT 1A, O appears, triggers the relay 16, opens contacts 17 and 22, and the photo photon stimulus 18 is turned off.

In deprivation drowsy, switch 20 closes and when the amplitude and gastrostate signals reach the set thresholds, relay 16 not only turns off the photofreeze terminal 18, {O and turns on bell 21, as a result of which the patient learns

The doctor can produce the required number of such sleep and sleep sleep cure cycles in the selected phase by adjusting the OD1N times the device to the patient's EEG, EMG, .j.U) during the preparatory reg.
