A method to perform security screening at an airport on hand-carried baggage. The method includes requesting passengers with hand carried baggage to remove from the baggage a container that holds a liquid and perform an x-ray inspection on the hand carried baggage and on the container while the container remains outside the baggage. According to the method, the results of the x-ray inspection are used to determine if the baggage contains illegal objects and if the liquid is a security threat.

Method and apparatus for assessing characteristics of liquids

A method for performing security screening of a liquid product at a security checkpoint is provided. The liquid product is placed in a tray having at least two reference areas manifesting respective X-ray signatures when exposed to X-rays, the X-ray signatures being distinguishable from one another. An X-ray inspection of the tray is performed while the tray holds the liquid product, the X-ray inspection including deriving the X-ray signatures. A determination is made as to whether the liquid product is a security threat at least in part based on the X-ray signatures. A tray having at least two reference areas manifesting respective X-ray signatures when exposed to X-rays is also provided.

Tray for assessing the threat status of an article at a security check point

A tray for holding an article while the article is being subjected to penetrating radiation is provided. The tray has a surface on which the article can be placed while subjected to penetrating radiation. The surface has at least two areas, namely a first area and a second area, the first and second areas characterized by first and second signatures, respectively when exposed to penetrating radiation, wherein the first signature is different from the second signature. The second area corresponds to a reference material having a reference signature. The tray is placed on the conveyor belt of a scanning apparatus while the article rests on the surface of the tray so that the conveyor belt may advance the tray through the screening area of the apparatus. A method and system for performing security screening and using the tray are also provided.

Tray for use in assessing the threat status of an article at a security check point

A method and apparatus for testing luggage screening equipment operators is provides. A sequence of images of contents of luggage items derived from a device that scans the luggage items with penetrating radiation are received. The image generation device is characterized by introducing a certain distortion into these images of contents of luggage items. A display device is caused to display images derived from this sequence of images. Occasionally, the display device is caused to show a simulated threat in a luggage item by displaying a combined image derived based at least in part on an image in the sequence of images and a distorted threat image. The distorted threat image was derived by applying a distortion insertion process to a reference threat image wherein the distortion insertion process tends to approximate the certain distortion introduced in the images of contents of luggage items by the device that scans the luggage items with penetrating radiation.
