Abstract
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.
Claims20
A tire sensor, comprising:
- a substrate:
- and
- at least one pair of motion sensitive sensors mounted on said substrate,
- wherein the sensors of the at least one pair of motion sensitive sensors are mounted on said substrate in a predetermined relationship to each other and at a predetermined distance from each other whereby selected tire characteristics may be ascertained by evaluating signals generated by the at least one pair of motion sensitive sensors.
A tire assembly, comprising:
- a tire;
- a substrate;
- and
- at least one pair of motion sensitive sensors mounted on said substrate,
- wherein the sensors of the at least one pair of motion sensitive sensors are mounted on said substrate in a predetermined relationship to each other and at a predetermined distance from each other and wherein said substrate is associated with said tire whereby selected tire characteristics may be ascertained by evaluating signals generated by the at least one pair of motion sensitive sensors.
A method for determining selected tire characteristics, comprising:
- providing a tire;
- mounting at least one pair of motion sensitive sensors a predetermined distance apart On a substrate;
- associating the substrate with the tire;
- rotating the tire;
- and
- evaluating signals generated by the at least one pair of motion sensitive sensors to determine selected tire characteristics.
