British Airport Authority purchases three CTX 5000s from InVision Technologies; FAA Certified CTX 5000s to be used at Heathrow International Airport.

FOSTER CITY, Calif.--(BUSINESS WIRE)--Sept. 16, 1996--InVision Technologies, Inc. (NASDAQ: INVN), manufacturer of the only Federal Aviation Administration (FAA) certified explosives detection system (EDS), today announced that the British Airport Authority (BAA) has purchased three additional InVision CTX 5000 units for use at Heathrow International Airport's Terminal 3. The contract also provides for a multi-year service agreement.

Of the three InVision CTX 5000 units, two are scheduled for delivery in the fourth quarter of 1996 and one in 1997. The devices will scan checked luggage for explosives and will become a critical component of Heathrow's Terminal 3 security procedures. The InVision CTX 5000 uses x-rays and computed tomography (or CAT scans) to detect all classes of explosives. BAA is currently operating one InVision CTX 5000 at Heathrow, which had originally been tested by the BAA at Gatwick Airport.

Heathrow is one of the busiest airports in the world, servicing more than 50 million passengers in 1995. The additional InVision CTX 5000s are part of an overall airport security infrastructure improvement taking place throughout the UK.

"We are pleased with BAA's decision to employ the InVision CTX 5000 as a critical component of its airport security measures," said Sergio Magistri, President and Chief Executive Officer of InVision Technologies. "As the InVision CTX 5000 provides the highest level of security available, we are hopeful that the BAA will choose to deploy additional systems in the future."

In addition to the UK, the InVision CTX 5000 is in use at international airports in Israel, Belgium, the Philippines and Japan. In the U.S. the FAA is currently sponsoring a series of InVision CTX 5000 operational demonstrations at the San Francisco International Airport and at Atlanta's Hartsfield International. The first commercially purchased unit in the U.S. was installed last week at John F. Kennedy International Airport in New York by EL AL Israel Airlines and will soon be operational.

To date, the InVision CTX 5000 is the only explosives detection system to receive certification status from the FAA, which verifies that the InVision CTX 5000 automatically detects small amounts of all classes of explosives, with a high degree of accuracy and a low false alarm rate. Unclassified portions of the FAA's certification standards are available in the U.S. Federal Register dated September 10, 1993.

The InVision CTX 5000 provides rapid and comprehensive detection of all categories of explosives even when they are concealed. The InVision CTX 5000 combines computed tomography (commonly known as CAT-scanning) and high quality x-ray imaging to produce clear, cross-sectional images of a bag ,s contents. Tomographic images are obtained by taking multiple cross-section views (or "slices") of an object. A powerful computer is used to reconstruct the slices and display the relative densities of the individual objects within each slice. This unique information allows the InVision CTX 5000 to automatically locate and highlight suspicious objects, regardless of their shape or environment. In contrast, traditional x-ray images are difficult to interpret because images of overlapping items are superimposed and cluttered.

InVision Technologies, Inc. develops, manufactures and markets advanced computed tomography-based explosives detection technology for the inspection of checked luggage on commercial airline flights. The Company is based in Foster City, California. Additional information about the Company can be obtained on the World Wide Web at: http://www.businesswire.com/cnn/invn.htm
