the number of bins they need. The lower false
alarm rate means less rechecks by staff.
Prior to the pandemic, airports and airlines
who knew CT equipment existed were
pushing it to improve throughput due to the
record numbers of travelers working their
ways through limited terminal space. Nordeen
says it now reinforces the idea of less
bags being touched.
" It means less bags being opened, the TSA
workers don't need to touch as much of your
stuff and secondary screening doesn't have
to happen because the false alarm rates are
lower, " she says. " It's almost a parallel argument
to deploy the technology quicker. "
Smiths was contacted by TSA to deploy
300 CT systems at 100 airports. They were
placed in a stand-alone fashion, but the addition
of Automated Screening Lanes (ASL) will
further help throughput.
" We designed the 6040 CTiX to be very
much a plug and play system to our current
multi-view 6040 ATiX that's already been
at airports, " she says. " We wanted to keep
the footprint very similar. We also designed
the electrical requirements to be the same so
there wouldn't need to be site work done to
increase the power requirements needed to
operate the systems. "
Lisa Farbstein, spokesperson for TSA,
says the new CT technology provides critical
explosives detection capabilities at the
checkpoint and improves the capability for
TSA officers to determine whether an item
inside a carry-on bag is a possible threat.
The system applies sophisticated algorithms
for the detection of explosives by
creating a 3D image that can be viewed and
rotated on three axes for thorough visual
image analysis by a TSA officer. If a bag
requires further screening, TSA officers
will inspect it to ensure that a threat item is
not contained inside. It's expected that it will
result in fewer bag checks. Plus, passengers
can be allowed to leave laptops and other electronic
devices in their carry-on bags.
" The 3D imagery of this new unit is so
good that our TSA officers can manipulate
the image on screen to get a better view of
a bag's contents and often clear items without
having to open a carry-on bag, " she says.
" Not only does this state-of-the art technology
represent an improved security threat
detection capability at the checkpoint, but it
also reduces the need for pulling aside a bag to
be opened, thus reducing a touchpoint during
the pandemic. "
Nordeen says Smiths Detection also developed
a modular UVC light sanitation module
that goes into the ASL. This allows each tray
to be sanitized between each use. They're currently
being used across the UK and Canada.
" Nobody likes to handle those bins, but
after COVID, that was a rapid engineering
moment that we saw an opportunity to solve
a problem very quickly knowing the impact
COVID was going to have within the first few
weeks on aviation and travel, " she says.
