PEL Associates has developed new,
and novel smart sensors which have direct application to securing
our shipping containers, ports, borders, aircraft, and airports which are considered vulnerable to
Current container inspection methods rely on slow and expensive manual
procedures, and on x-raying and gamma ray inspection techniques, and
the use of radiation detectors on specific containers of interest.
Rarely can more than a small percentage of the sixteen million containers
arriving each year be
adequately inspected, and any uninspected container can pose
PEL Associates is developing low cost, passive polymeric
film sensors to be placed within each container to address this
problem. These sensors will
respond to hazardous materials such as CBW agents or radioactive
substances by displaying a specific color or conductivity level
indicative of a particular hazard. The mechanism involves sensing
element responders which react with the vapor of CBW materials to
produce a specific color, or which change conductivity upon sensing
a particular type of incident radiation. The cost of such film
sensors is estimated to be less than $5 each. This method
should allow for 100% of containers inspected 24/7.
PEL's smart, low cost, passive micro-sensors can
be tailored to detect unauthorized vehicles or swimmers entering a
port. These sensors can be so arranged for specific port type,
topography, and operations.
The technology should be applicable to both
commercial and government ports and could be a unique and important
aspect of overall port protection requirements. Examples include
near shore chemical plants, nuclear power plants, and military
bases. The sensors can also protect battle groups or precious
monuments like the Statue of Liberty.
Unattended ground smart sensor system was
developed to detect and communicate the presence of border crossing
events. The approach consists of a detection and communication
processing system capable of high probability of detection and no
false positives. Specific activation and emitted indicators
detect and differentiate between people, vehicles, or particular
animals. Communication is provided by PEL state of the
art Gen I-III detection systems
Planes caught in bad icing conditions have no
good alternative once icing develops and possibly drives the plane
down and out of control. Planes currently, waiting to enter
the runway and those positioning for takeoff must be repeatedly
washed with anti freeze which is a slow, costly, method with short
lifetime. PEL's renewable micro coatings will automatically deice
aircraft on command, leaving a clean surface and placing the planes
back under safe control.
Strong wind shear downdrafts can occur in
takeoff and landing areas. Planes caught in such downdrafts
have no alternative once wind shear develops and often drives the
plane to crash. With early wind monitoring and detection by
PEL's new nano-sensors, planes can be alerted, diverted or detained
until it is safe.
Adjacent airport areas have become
vulnerable to terrorists aiming shoulder held rockets from "manpads" at incoming and out-going
aircraft. PEL's ground-based micro sensors will instantaneously
detect terrorists and signal for automatic interdiction placing the
airport and vulnerable planes back into safe operation.
