The invention relates to medical technology and can be used in diagnostic devices, in particular, to assess the health of a person in the conditions of modeling the pair interaction.

The aim of the invention is to increase the reliability of the measurement information.

The goal is achieved by the fact that a stop unit, a multiplexer, a measuring unit, a third and fourth display units are entered into a device for examining the group activity of operators containing a signal selector, a calculator, first and second display units, whose inputs are connected to the first output of the calculator the first inputs of which are connected to the output of the measuring unit, and the second inputs are connected respectively to the first and second outputs of the multiplexer, the first

The clock pulse arrives at the first input of the device, setting the triggers 10 and 11 to their initial state. The next wired signal, say at the second input of the trigger 10, passes to the output 36 of the signal selector and blocks the signal from the third input of the device

JQ to the output 37 of the selector 1. The signal from the third input of the device, having appeared later blocks the further passage of the signal at the output 36. Thus, the duration of the signal to

15 output 36 is equal to the time interval from the moment the signal appears at the second input of the device to the time the signal appears at the third input of the device, i.e. equal to the time difference of the reaction of the operators. The active signal from the output 36 of the selector 1 is fed to the input of the block 5 and stops at its output 38, then it goes to the inputs of the calculator 2,

yen respectively with the first and second inputs of the calculator, multiplexer and measuring unit, the first and second inputs of the stop unit are connected to the first and second outputs of the selector, the signals whose inputs are device inputs, the second output of the calculator is connected to the third input of the stop unit.

FIG. 1 shows a functional diagram of the proposed device; in fig. 2 - functional block diagrams of the device.

The device contains a signal selector 1, a calculator 2, the first 3 and second 4-block indication, block 5 stop, multiplexer 6, the measuring unit 7, the third 8 and the fourth 9 display blocks. The selector 1 includes triggers 10 and 11, the elements for operators are much faster (copper-HE 12 and 13. Measuring unit 7 contains elements Y-HE 14-17, generator 19 pulses, one-shot 18 and counters 20 and 21. Block 5 stop contains the elements AND-NOT 22-25, the trigger 26, the key 27. The multiplexer 6 contains the key 28, the triggers 29 and 30, the element OR 31, the elements AND-NOT 32-35. In Fig. 1 and 2 are indicated the outputs 36 and 37 of the selector 1 signals and outputs 38 and 39 of the block 5 stop.

The device works as follows.

If the first signal appears at the third input of the device, respectively, the signals at inputs 37 and 39 are active, the control information is also displayed, in blocks 8 and 9. If from the second output of the calculator 2 the overflow signal goes to the third input of the stop unit 5, then operation of the device stops until the next cycle.

block 7. Pass through multiplexer 6, the signal turns on the indicator label in display block 8, which shows that the first operator is ahead, and prepares it to display information from the measuring unit 7. At the same time, the active signal at the input 38 of the measuring block with its leading edge It starts the one-oscillator 18, which, with a short pulse at its output, sets the counters 20 and 21 to the initial state. All the time the active state of the signal at the input 38 of the measuring unit 7 to the input of the counter 20 receives pulses from the generator 19 through the element IS-NOT 15. The output signal of the counter 20 is fed to the first inputs of the blocks 8 and 9 of the display, showing
