Abstract: A detection system for an aircraft that includes at least one chemical sensor or an array of nanofiber chemical sensors for sensing an airborne material. The chemical sensor has an electrical characteristic that changes in the presence of the airborne material. The system further includes a processor coupled to the chemical sensor. The processor monitors electrical characteristic of the chemical sensor and generates a detection signal in response to a change in the electrical characteristic.

Abstract: An air quality system for a vehicle includes a chemical detection apparatus including a plurality of nanofiber chemical sensors for sensing a plurality of airborne materials in a compartment of the vehicle. The plurality of nanofiber chemical sensors are configured to adjust a characteristic electrical signal in response to changes in the presence of the plurality of airborne materials. The chemical detection apparatus further includes a processor coupled to the nanofiber chemical sensor, wherein the processor is configured to monitor the characteristic electrical signals from the nanofiber chemical sensors and generate a detection signal in response to a change in the characteristic electrical signals. The processor is in communication with a controller configured to control at least one vehicle system in response to the detection of one or more of the airborne materials.

Abstract: A detection system includes at least one sensor configured to measure a presence of airborne particles and at least one amplifier circuit in communication with the at least one sensor. The amplifier circuit is configured to monitor a charge generated by the at least one sensor over a time interval. The system further includes a controller configured to monitor the charge accumulated in the at least one amplifier circuit from the at least one sensor at the time interval. In response to the charge of the at least one amplifier circuit, the controller detects the presence of the airborne particles.
