L-3 Communications is participating in the second phase of the Department of Homeland Security's Rail Security Pilot project, which will screen transit passengers for explosives. This phase of the project will use L-3's ProVision body screening portal at the Port Authority Trans Hudson Corp.'s Exchange Place Station in Jersey City, N.J. The trial was scheduled to start today and last for two weeks. The screening system reveals the presence of explosives and concealed objects anywhere on the body in as little as two seconds. The ProVision system uses non-ionizing active millimeter wave-imaging technology to detect virtually any material, including wire, liquid, ceramic, plastic and metal. L-3's body-screening portals are featured at railways stations in the United Kingdom, border crossings in Israel and international airports.
