A method and system for airport or other building security where passengers or persons entering a building approach a check-in point or check-in counter and must undergo a positive identification (ID) by fingerprint scan, retinal scan, or an other means of positive identification. A digital photograph can then be taken of the person. This data plus the positive ID data and optional data about the person including a scan of a government supplied ID like a drivers license or passport is entered in a database and checked against various law enforcement databases such as FBI or others for law enforcement interest in the person. The person is given an electronic smartcard that has wireless capability. The person carries the smartcard while in the airport or building. The system is notified when the person enters a secure gate area, boards or leaves an aircraft, etc. In addition, the system can determine if a person is carrying more than one smartcard or if a card has been abandoned. The system detects and tracks any undesirable person in the airport or building an provides a means for apprehending the person by security or law enforcement personnel. In addition, immigration or customs can be notified about any undesirable person arriving in an airport. The system allows airline personnel and security personnel to know when an unexpected or unwanted event or person is in the system.

Large-area individually addressable multi-beam x-ray system and method of forming same
A structure to generate x-rays has a plurality of stationary and individually electrically addressable field emissive electron sources with a substrate composed of a field emissive material, such as carbon nanotubes. Electrically switching the field emissive electron sources at a predetermined frequency field emits electrons in a programmable sequence toward an incidence point on a target. The generated x-rays correspond in frequency and in position to that of the field emissive electron source. The large-area target and array or matrix of emitters can image objects from different positions and / or angles without moving the object or the structure and can produce a three dimensional image. The x-ray system is suitable for a variety of applications including industrial inspection / quality control, analytical instrumentation, security systems such as airport security inspection systems, and medical imaging, such as computed tomography.
