METHOD AND DEVICE FOR MICROSLEEP DETECTION Russian patent published in 2015 - IPC A61B3/10 A61B5/476 A61B5/496 B60K28/06 G08B21/06 

FIELD: medicine.

SUBSTANCE: group of inventions refers to medicine and medical equipment. A distance of the upper to lower eyelids of at least one eye is measured over a period of time, Eye openness coefficients varying within the value of wide open eye, through the value of partially open eye to the value of completely closed eye are determined. The eye openness coefficients are graphed. The eye openness coefficients variations over the period of time are compared to a reference eye closure model indicating the microsleep cases. Besides, the method is implemented according to the version, which provides notifying an operator if the microsleep has been detected, by signalling. The method is also implemented by comparing the microsleep models with the eye openness coefficients variations as shown by EEG and EOG. That is ensured by using a device comprising an infrared emitter, which is connected to an image selector. A microprocessor with an electronic procedure of microsleep detection configured to detect face, eyes and eyelids images in a digital image and to calculate the eye openness coefficient with determining a microsleep-specific coefficient, and presenting the obtained information in the form of graphical presentation of the eye openness coefficients at the selected moments of time. A memory unit connected to the microprocess and comprising the reference eye closure models to be compared to the eye openness coefficients at the selected moments of time.

EFFECT: invention enables providing the more reliable assessment of microsleep that is ensured by microsleep detection at the early stages of falling asleep.
