First Claim
Patent Images
1. A system for determining the pressure of a pneumatic vehicular tire while mounted on the wheel of a vehicle, comprising:
- a. A two-dimensional array of load sensors which provide a two-dimensional pattern of the force distribution exerted by said tire in contact with said sensors while the vehicle is moving or at rest on said arrayb. a computer which is programmed (programmed computer) to determine said tire inflation pressure from said force distribution data independent of the make or model of said tire and said vehicle; and
c. means for displaying said pressure.

Abstract
A system that will indicate tire inflation. A two-dimensional array of sensors is used to determine the distribution of contact forces over the footprint of a pneumatic tire. A neural network may be employed to classify the patterns of force sensed in this manner, and to closely estimate the actual tire inflation pressure.
