A personal breathing apparatus installed in an aircraft that is not fully pressurized, and configured to prevent or treat an adverse physiological event. The personal breathing system is configured so as to prevent, lessen or reverse hypercapnia by (i) facilitating removal of carbon dioxide generated the pilot by controlling pilot ventilation and/or (ii) limiting or decreasing the amount of carbon dioxide generated by the pilot by controlling the amount of oxygen breathed by the pilot.

An object is to provide a technique capable of accurately determining an awakening degree. An awakening degree determination apparatus includes a change amount acquisition unit, a frequency calculation unit, and an awakening degree determination unit. The change amount acquisition unit acquires an angle change amount, an inclination change amount, and a position change amount. The frequency calculation unit calculates an angle frequency, an inclination frequency, and a position frequency. When at least one of the angle frequency, the inclination frequency, and the position frequency exceeds a fourth threshold value, a fifth threshold value, and a sixth threshold value, the awakening degree determination unit determines that an awakening degree of a driver of the vehicle decreases.

An apparatus and method for monitoring a vehicle driver having at least one sensor for measuring pressure and/or humidity. The sensor includes at least one capacitor having at least two electrodes, which may be arranged horizontally on a flexible support material. At least one dielectric layer may be arranged between the electrodes. At least one electrode, and/or the dielectric layer, and at least one, at least partially liquid-permeable and/or liquid-absorbing moisture layer may be arranged on a side facing away from a support material. At least one electrode and/or the dielectric layer may be arranged transversely between the support material and the moisture layer. A capacitance may be changed by liquid on the dielectric layer, and a processing unit measures and/or stores values from the sensor, creating a capacitive humidity sensor. The processing unit may send the to a central CPU, wherein this data may be processed by the processing unit.

A method is disclosed for driving an emergency reaction system within a moving motor vehicle carrying at least one vehicle occupant. The method includes monitoring health conditions of the vehicle occupant. The method also includes determining whether the health conditions are below a critical threshold and, if so, continuing to monitor the health conditions of the vehicle occupant. If the health conditions exceed the critical threshold, an emergency alert is issued without waiting for the motor vehicle to stop, and an autonomous safe stop maneuver is performed if the motor vehicle is moving autonomously or includes an autonomous driving system and is allowed to operate automatically.
