ETV highlights TPMS at show
SYDNEY, Australia-ETV Corp. Pty. Ltd. of Sydney demonstrated its VisiTyre batteryless tire pressure monitoring system at the recent Society of Automotive Engineers World Congress in Detroit.
The company said the system reports pressures and temperatures on all four wheels plus the spare continuously from the moment of ignition, whether the tires are stationary or rotating.
ETV said the system is not disabled by tire replacement because it is ``inherently transparent'' to all tires regardless of content.
The device uses electromagnetic inductive coupling to create a ``power in, data out'' non-contact communication channel in each wheel sensor. It does not need wheel module batteries or the radio frequency communication of other systems.
Quik-Chek unit re-engineered
CORAL SPRINGS, Fla.-Automotive Aftermarket Products Inc. has unveiled a re-engineered version of its Quik-Chek tire pressure indicator and hopes to gain more distribution for the product, including among tire dealers.
President Ray Huffman said the device can be installed right after new tires are mounted and the correct pressure is set. Tire dealers then can explain to motorists how to use the device.
The Quik-Chek devices mount on the valve stem and, when pressed, indicate whether tire pressure is optimal, high, low or dangerously low by color-coded bars. The indicators do not show pressure continuously but only when pressed. With the color-coded bars, Mr. Huffman said, motorists need only remember the colors' meanings, not their specific tire pressure range.
The company also is developing a similar product that can be attached to a keychain to address concerns about theft of the device.
The units retail for about $19 to $24.95.
