Abstract

Sposób monitorowania ruchu powiek zwłaszcza w urządzeniach ostrzegających o zasypianiu lub dekoncentracji, polega na tym, że umieszcza się w sąsiedztwie co najmniej jednego oka źródło promieniowania optycznego generujące co najmniej jedną wiązkę promieniowania optycznego i co najmniej jeden detektor promieniowania optycznego, oświetla się co najmniej jedno oko co najmniej jedną wiązką promieniowania optycznego o natężeniu mniejszym niż natężenie powodujące reakcję oka na oświetlenie wiązką promieniowania optycznego, generowaną przez źródło promieniowania optycznego, mierzy się natężenie odbitej wiązki promieniowania świetlnego za pomocą detektora promieniowania optycznego i porównuje się z wartością optymalną którą stanowi wartość natężenia gdy powieki oka są otwarte i oświetlana jest gałka oczna z wartością natężenia odbitej wiązki w chwili gdy powieki są zamknięte, analizuje się czas trwania wartości natężenia odbitej wiązki w chwili gdy powieki są zamknięte oraz generuje się sygnał alarmowy w przypadku gdy czas trwania mierzonej wartości natężenia odbitej wiązki jest równy/dłuższy od maksymalnego dopuszczalnego czasu trwania wartości natężenia odbitej wiązki dla normalnego mrugania oczu. Urządzenie monitorujące ruch powiek zgodnie z wynalazkiem zawiera konstrukcję nośną (1) do której zamocowane jest co najmniej jedno źródło (2.2) promieniowania optycznego i co najmniej jeden detektor (3.1) promieniowania optycznego, układ sygnalizacji (3.3) oraz co najmniej jeden układ zasilający (4) połączony z układem sygnalizacji (3.3). Ponadto zawiera co najmniej jeden układ sterujący (2.1) połączony ze źródłem (2.2) promieniowania optycznego, oraz co najmniej jednym układem (3.2) kształtującym i przetwarzającym poziom sygnału połączony z detektorem (3.1) promieniowania optycznego i układem sygnalizacji (3.3), przy czym układ sterujący (2.1) i układ (3.2) kształtujący i przetwarzający poziom sygnału połączone są z układem zasilającym (4).The method of monitoring the movement of the eyelids, especially in devices that warn about falling asleep or distraction, consists in placing in the vicinity of at least one eye an optical radiation source generating at least one optical radiation beam and at least one optical radiation detector, illuminating at least one eye at least one beam of optical radiation with an intensity lower than the intensity causing the eye's reaction to illumination with the beam of optical radiation generated by the optical radiation source, the intensity of the reflected light beam is measured with an optical radiation detector and compared with the optimal value, which is the intensity value when the eyelids eyes are open and the eyeball is illuminated with the intensity value of the reflected beam when the eyelids are closed, the duration of the intensity value of the reflected beam is analyzed when the eyelids are closed and a signal is generated alarm if the duration of the measured value of the intensity of the reflected beam is equal to / longer than the maximum permissible duration of the intensity of the reflected beam for normal eye blinking. The device for monitoring the movement of the eyelids according to the invention comprises a support structure (1) to which are attached at least one optical radiation source (2.2) and at least one optical radiation detector (3.1), the signaling system (3.3) and at least one power supply system (4). ) connected to the signaling system (3.3). Moreover, it comprises at least one control circuit (2.1) connected to the optical radiation source (2.2) and at least one signal level shaping and processing circuit (3.2) connected to the optical radiation detector (3.1) and the signaling circuit (3.3), the circuit being the control unit (2.1) and the signal level shaping and processing circuit (3.2) are connected to the supply circuit (4).
