  • Method and system for an accelerated reaction of darkening of the optical device in personal protective equipment
    Patent number: 10945887
    Abstract: System has an optical sensor (1), an aperture with the optical element (2) with the changeable permeability and an activation light (3) emitting radiation, which is detected by the optical sensor (1). The activation light is connected with the switch (4) and it is placed within the reach of the optical sensor (1). Within a device which realizes the technological process with the luminous manifestation the instruction for the beginning of a given technological process is detected and on the basis of this instruction the activation light (3) lights up. This activates the optical sensor (1) by means of the activation light (3) before the optical sensor (1) detects the luminous manifestation of the technological process itself. The activation light (3) can be a simple infrared LED diode.
