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 authentication system includes a communication circuit configured to communicate with a remote server and at least one scanning apparatus configured to capture biometric data. The system further includes a controller in communication with the communication circuit and the scanning apparatus. The controller is configured to receive a request for a security authorization and capture the biometric data with the scanning apparatus. The controller is further configured to compare the biometric data to authentication data. The authentication data includes an identification profile configured to authenticate a previously identified individual. The controller is further configured to authenticate the previously identified individual based on the identification profile and communicate a privilege level associated with the identification profile to the air travel device.
