Abstract

See full text

Disclosed is an apparatus and methodology for monitoring tire related conditions. A substrate is provided having one or more pairs of sensors mounted thereon. The pairs of sensors are mounted in predetermined relationship to each other at predetermined separation distances such that rotational direction, speed and other parameters of a tire with which the sensors may be associated may be determined. In some embodiments, plural effective pairs of sensors are provided so that mounting orientation of the sensor need not be predetermined.
