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 systemÂs 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.
ÂThe VisiTyre Inductive Coupling Technology provides a real solution for many of the contentious safety issues of the Final Rule of the TREAD ACT ÂÂ commented Phil Cohen, ETVÂs Chief Technical Officer, ÂTPMS 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 contentÂ.
VisiTyre utilises electromagnetic inductive coupling to create a Âpower in - data outÂ 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 vehicleÂs metallic components whilst the vehicle is stationary.
ÂThe 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, couldnÂt possibly be regarded as a safety systemÂ said ETV Chief Operating Officer Gregg Eichhorn, Âparticularly 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.Â
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. NHTSAÂs 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.
