Rapidly screen individuals for trace amounts of explosives
with PassPort™, our turnstile-based Energetic Material Detector. This
walkthrough system delivers accurate results in seconds
and supports high throughput rates with a user-familiar
turnstile design. The system utlizes the patent-pending
Energetic Material Detection technology for sensing trace
amounts of any explosive without the use of a reference
library and provides an enhanced level of detection never
before seen.

DESIGN PassPort™ was designed to facilitate high throughput while ensuring
high levels of confidence that screened personnel were not
carrying or exposed to explosives. This was accomplished
by designing a user-familiar architecture that millions
of people are accustomed to using
each day. The turnstile design is used by many organizations
to perform unique functions ranging from monitoring throughput
at theme parks to restricting admission to paying clients
at mass transportation entry points. The wide-use and acceptance
of this technology was instrumental
its selection since it would be rapidly recognized
by the general public and reduce or eliminate altogether
the need to educate subjects.
Accompanying
this familiar architecture is an equally rapid analysis
for explosives. Within seconds after a person exits the
turnstile, a determination is generated as to whether the
person has tested positive or negative for trace amounts
of explosives. Immediately after these results have been
provided, the turnstile is ready to process the next subject.
DETECTION
ENGINE
PassPort™ is powered by a patent-pending technology called
the Energetic Material Detector (EMD). This technology also powers our OptEX™ system and
relies on the fact that all explosive materials, regardless
of the amount, decompose exothermically after being supplied
with sufficient activation energy. The subsequent decomposition
process results in an intense release of heat to the environment
surrounding an explosive particle, producing a localized,
sharp increase in temperature. It is possible to recognize
this heat signature as indicative of an explosive material
and thus rely solely on the thermodynamics accompanying
the
decomposition of any explosive material for its detection.
As a result, any explosive, whether previously documented
or newly created, can be detected simply by its explosive
characteristics. As a result, the EMD eliminates the need
for reference libraries, maximizes probability of detection
and simultaneously minimizes the probability of false alarm
for all explosives.
