July
2003: Tark's
new cooling
system for
InVision's
CTX 9000 explosives
detection system,
becomes the
first to complete
rigorous HALT
(Highly Accelerated
Life Testing)
and acceleration
testing at
Sypris Labs
in Burlington,
Massachusetts.
These tests,
designed to
induce loads
well beyond
specs for the
purpose of
determining
potential weaknesses
in its design,
included various
combinations
of temperature
(from -20 to
80 C), vibration
(up to 41 GRMS)
and acceleration
(up to 60 G). |

June
2003: Tark
is issued a
patent for
its venturi/accumulator
assembly. This
assembly allows
a positive
pressure to
the pump's
inlet during
operation but
ambient pressure
throughout
the system
when off. The
former prevents
pump cavitation
and the latter
prevents leaks
or air entrapment.
Furthermore,
it also greatly
simplifies
flow sensing
because a single
pressure reading
at the venturi's
outlet is a
direct and
very accurate
indicator of
flow. |

March
2003: Tark
builds first
production
multi-stage
oil pump for
GE Medical
Systems' new
flagship Hercules
tube. The pump,
Tark's HDD
80, uses two
impellers at
each end of
the pump to
essentially
provide the
performance
of two single
stage pumps
in the space
of one. This
pump is already
being used
in the industrial
market, with
the airport
based explosives
detection CT
scanners. |

February
2003: Tark's
cooling system
for the L3
EXACT airport
luggage scanner
is approved
by L3, the
supplier to
the Transportation
Security Administration.
It will be
installed in
the L3 EXACT
explosives
detection systems
beginning with
the '03 TSA
order. |
