| titleOfInvention | Sensor for pilot mask |
| abstract | A mask is shown which is used for providing air or oxygen for breathing. The mask has a differential pressure sensor for providing a signal to control oxygen or airflow to the mask. In one form the sensor is in the wall of the mask or in a wall of a supply tube, to sense the differences between ambient pressure, for example in the cabin of an aircraft, and pressure in the breathing space on the interior of the mask. Reduction in the pressure on the interior of the mask can indicate that a pilot is not receiving adequate oxygen, or is being subjected to stresses that may result in blackouts or red outs. The signal from the differential pressure sensor is used to control the flow of oxygen to the mask, and also can be used for controlling the pressure of pressurized suits worn by the pilot. The pressure sensor output also can be used to maintain a higher pressure on the interior of the mask to insure ambient air does not contaminate the air being breathed. |
