U.S. Army and U.S. Marines Re-Affirm Their Commitment to InVision Technologies' Quadrupole Resonance Landmine Detection Technology.

NEWARK, Calif.--(BUSINESS WIRE)--March 15, 2000

InVision Technologies, Inc. (Nasdaq:INVN) today said that Dr. Fred Saafeld, Executive Director and Technical Director of the Office of Naval Research (ONR) announced that the U.S. Army Project Manager for Mines, Countermine and Demolitions has initiated a program to further develop and field quadrupole resonance equipment for landmine detection on roads, and the U.S. Marines Corps plans to pursue a program to field quadrupole resonance for handheld detection applications.

Dr. Saafeld's opening Communication, made at the Fourth International Symposium on Technology and the Mine Problem being held this week by the Naval Postgraduate School in Monterey, California, went on to say that RADM Paul D. Gaffney, USN, the Chief of Naval Research, has pledged every effort to make the developments achieved under InVision Technologies, Inc.'s wholly owned Quantum Magnetics' DARPA landmine detection system program available to the Marine Corps as a man-portable QR-based landmine detection system.

The full text of DARPA's recent press release regarding Quantum's successful field trials of its QR-based landmine detection system rounded out the balance of the Communication to open the Symposium. The full text of DARPA's press release can be found @ http://www.darpa.mil.

Dr. Lowell Burnett, Quantum's founder and Chief Technology Officer, was invited by the Symposium to present Quantum's paper entitled "Mine Detection Systems using Quadrupole Resonance." This paper also became part of the proceedings of the Conference.

"The prominent position accorded to Quantum's achievements in landmine detection at this prestigious Symposium is another indication of the support that we are receiving to transition our DARPA program to two large scale development efforts. With the support of the Office of Naval Research and the U.S. Army Quantum will develop man-portable and vehicle-based versions of its QR landmine detection system," remarked Sergio Magistri, President and CEO of InVision Technologies.

"We are committed to placing a QR-based landmine detection system in the hands of our Armed forces as well as humanitarian de-miners throughout the world," Magistri added.

The Quantum system is based on quadrupole resonance (QR), which applies a radio-frequency magnetic-field pulse at a frequency specific to individual explosive compounds. Unlike other technologies, which do not detect the mine's explosive charge, QR can serve as both a primary and confirmation sensor, enabling the system to resolve its own false alarms.

The current QR prototype system detects metal, RDX, TNT and Composition B, and is thus able to detect the vast majority of all landmines deployed throughout the world. Future systems are expected to be able to detect Tetryl as well. QR has the ability to operate in almost all soil conditions including saturated soils, as well as through water.

Quantum Magnetics, acquired by InVision Technologies in September 1997, develops and commercializes patented and proprietary technologies, including key QR patents licensed from the Naval Research Laboratory, that are based on a state-of-the-art, low-cost version of magnetic resonance adapted for explosive detection. InVision Technologies develops, manufactures, markets and supports explosive detection systems based on advanced Computed Tomography (CT) technology for civil aviation security.

Today, more than 180 FAA-certified CTX systems have been shipped worldwide to provide the traveling public with the best security against terrorism available. The company also develops, manufactures, markets and supports CT-based systems for other applications, including wood scanning and drug detection.

InVision's wholly owned subsidiary, Quantum Magnetics, develops and commercializes patented and proprietary technologies. These include, but are not limited to, Quadrupole Resonance (QR) patents licensed from the Naval Research Laboratory, that are based on state-of-the-art, low-cost version of magnetic resonance adapted for explosive detection.
