ETV Corporation applied serious pressure to its competitors with its
‘real time’ display of their VisiTyre Tire Pressure Monitoring System at SAE
2005 World Congress in Detroit Michigan. Automotive Engineers showed intense
interest in the system’s battery-less sensors and immediate reporting
capability on ignition.
Sydney, Australia (PRWEB) June 3, 2005 -- As one of the few interactive
displays at this years SAE World Congress and the only TPMS technology company
in attendance, VisiTyre drew a continuous stream of industry delegates to
their Australian Trade Delegation booth, where a real time demonstration
system highlighted the system’s ability to immediately report pressures and
temperatures of all four wheels plus the spare continuously from the moment of
ignition, whether the tires were stationary or rotating.
“The VisiTyre Inductive Coupling Technology provides a real solution for many
of the contentious safety issues of the Final Rule of the TREAD ACT ’’
commented Phil Cohen, ETV’s Chief Technical Officer, “TPMS disablement by tire
replacement is just not an issue with VisiTyre technology, it is inherently
transparent to all replacement tires regardless of ferrous or carbon content”.
VisiTyre utilises electromagnetic inductive coupling to create a ‘power in -
data out’ non contact communication channel to each of the vehicles wheel
sensors, dispensing with the need for wheel module batteries and the
unsatisfactory Radio Frequency communication channel of alternative systems.
It is this use of RF technology with its limited power density due to the
sensor batteries and associated radio path interference problems that creates
the inability for these systems to operate through the vehicle’s metallic
components whilst the vehicle is stationary.
“The consensus of comments from engineers stopping at our SAE display, in
regards to the Final Ruling, was that allowing up to 20 minutes after the
vehicle has moved off into the traffic for the TPMS systems to report to the
driver, couldn’t possibly be regarded as a safety system” said ETV Chief
Operating Officer Gregg Eichhorn, “particularly as they were seeing our
VisiTyre TPMS working in front of them on all five tyres, with and without
wheel motion and as soon as the ignition powered up the system. Clearly NHTSA
has got it wrong if this is to be a safety system.”
With the availability of the VisiTyre inductive coupling technology, life
should become much easier for the OEM and body electronics companies who are
currently having to assess the most appropriate systems for implementation and
compliance with the TREAD Act 2000 TPMS Mandate. NHTSA’s Final Ruling, which
if unchallenged, will come in to force in October 2005, requiring 20% of MY
2006 passenger vehicles to be integrated with TPMS.
