TECHNIQUE FOR CONTROLLING OPENING AND CLOSING OF A PROTECTIVE MASK

A technique for controlling an actuator of a protective mask configured to assume selectively a closed state for respiratory protection and an open state is described. A respiratory flow resistance of the open state is reduced compared to a respiratory flow resistance of the closed state. As to a method aspect of the technique, at least one information signal indicative of an environment of the protective mask is received. A control signal is sent to the actuator of the protective mask for assuming selectively the closed state and the open state depending on the at least one information signal.
