Film projection chronoreflex. meter has:

film projection unit 1, screen 2, photoelectric counter 3 frames, sensors 4 for the reaction of the subject, block 5 for controlling the reverse of the film projection unit, node 6 for programming the time sequence of signals, block 7 for the memory of codes of presented frames, reversible counter 8, trigger 9, block 10 delays, electronic key 11, electronic key 12, reference element 13, output register 14 of the memory block, response time analyzer 15, block 16 of response time measurement test, p1, memory block 17 of the response time reference value, block 1 8 comparisons, the output register 19 of the memory block of the reference reaction time values, the trigger input 20, the trigger output 21, the summing input 22 of the reversible counter, the recorder 23, the second trigger input 24, the second output 25 of the trigger, subtracting the reversible counter input 26,

Chronoreflexometer works as follows.

The experimenter enters into the memory block 7 codes of codes of the pre-ejx film frames, and in block 17 - the reference values of the reaction time for presented frames. In this case, from block 7, the code of the first presented movie frame is automatically entered into its output register 14, and from block 17, the reference (maximum allowable) value of the response time to the first presented movie frame is entered into its output register 19. Next, the experimenter, acting on the input 20 of the trigger 9, sets at its output 21 a high potential; level. At which the output of the photoelectric counter of 3 frames is connected via the electronic key 11 to the summing input 22 of the reversing

counter 8. When switching on a film projection installation 1, the subject on screen 2 is presented with various professional situations. At the same time, summing input 22 of reversing counter 8 begins to receive electrical signals generated by photoelectric counters 3 frames at the moment of time, when the light from the bulb as it passes through the perforation holes of the film hits the photomultiplier of the photoelectric counter of 3 frames. Since the signals from the output of the photoelectric frame counter are fed to the summing input 22 of the reversing counter 8 continuously with the projection of the film (pulling the film), then at some point in time when the contents of the reversing counter 8 coincide with the contents of the output register 14 of the memory 7 at the output Comparison element 13, a pulse signal is generated that triggers the test response time measurement unit 16. The test reaction time meter of the test subject is stopped by the test reaction sensors 4. After block 16 is stopped, the content (the numerical measure of the measured response time to the test frame presented to the subject) is compared with the contents of the register 19 of the memory block 17, i.e., the numerical measure of the reference value of the response time to the presented film frame. In case the measured value of the response time does not exceed the reference value, the output registers 14 and 19 automatically enter the code and the reference value, respectively: the response time of the next presented kiaokadr. At the same time, the counter 8 continues to operate in the summation mode, the pulse signals from the output of the photoelectric counter of 3 frames, and the block 16, after being recalculated, its signal to the α-recorder 23 is set to zero and the above described procedure is performed again, but frame to be assigned. In the case when the measured value of the reaction time exceeds the reference value, at the output of the analyzer comparing unit 18, the reaction time produces a pulsed signal, as a result of which projection is stopped using block 5 (pulling the film). Simultaneously, the trigger 9 at input 24 is set to a state in which a low potential level is fixed at its output 21, and a high potential level at its output 25, which allows connecting the output of a photoelectric counter 3 frames across the key 12 and read the reverse counter input 26 8. Next, block 5 carries out the reverse of the film projection installation 1 (pulling the kinaanta in the opposite direction). In this case, the number of frames processed in the reverse direction for a time equal to the delay time generated by block 10 is subtracted from the contents of the reversible counter. After the delay time p versus of the projection stops and the trigger 9 on the input 22 is reset. The output of the photoelectric counter of 3 frames is again connected via the key 11 to the summing input 22 of the reversing counter 8. Next, block 5 turns on the projection unit 1 in the forward direction and the time measurement process repeats The response to the film frame, the code and the reference value of the reaction time of which continues to be stored in the output registers 14 and 19. The repeated reverses of the projection of the camera continue until the test response time becomes less than or equal to the reference value of the test In the course of the experiment, the unknown person takes up his workplace, acts on the controls of the workplace with the sensors of the test subject attached to them, reacting to changes in the position of the control elements In the workplace, the rfa screen 2 is designed to change the professional situation, simultaneously affecting all the senses of the subject.
