In an obstacle device, a front end range imaging sensor is used to scan the viewing field relative to the aircraft, while a navigation system provides information concerning the postion and altitude of the aircraft. The chambers of the airbag includes a vehicle sidewall chamber that can be deployed around a shoulder region of the occupant and a compartment chamber that is disposed closer to the inner side of an occupant compartment in the vehicle width direction than the vehicle sidewall chamber and can be deployed around a chest region of the occupant. In this manner, the tungsten scavenges or inactivates iron that can otherwise poison catalytic converters, sensors andor automotive on-board diagnostic devices andor reduce the operation of spark plugs. The TC can, for example, be an automated tool that performs various functions including: verifying the consistency of security criteria, generation and deployment of consistent security criteria, and transformation of security criteria to parts andor forms suitable for various computing environments. A method for dimming one or more light sources is also disclosed. The composite image employs the best information available regarding the subject of the scan and this information is used to constrain the reconstruction of highly undersampled image frames.
