METHOD OF DETERMINING WORKABILITY OF HUMAN OPERATOR Russian patent published in 2006 - IPC A61B5/16 

FIELD: medicine; occupational hygiene.

SUBSTANCE: variable frequency signals are presented to tested person being at rest or at tired condition and factors of his/her reaction to the signals are measured. Signals shown to tested person are formed in shape of tests to be solved. Conditions and result of the tests are shown on screen of videocontroller. Number of tests for persons being at relaxed or tired condition are preset to be equal. The test are shown in random sequence at frequency being changed proportionally to frequency of their solving. Total time from beginning till end of solution needed for preset test is measured as well as total time of delay in outputting shown conditions of tests and results of their solution to screen of videocontroller when taking corrections into account. Number of tests solved right is determined and total time for solving the tests deducting the time for making corrections is measured. Workability is estimated on the base of change in average time for making right solution of the test. Method provides independence of results on equipment used for the tests.

EFFECT: improved truth of estimation.
