Abstract:
A flat tire sensing system, comprising:(a) a pair of pressure sensing assemblies positioned on a roadway at spaced apart positions so as to intercept both wheels of a vehicle when driven over said pressure sensing assemblies;(b) a plurality of pressure sensing elements in each of said pair of pressure sensing assemblies, each of said pressure sensing elements operative to measure pressure applied thereto and spaced apart a distance such that at least one of said pressure sensing elements is positioned under each wheel of all wheels on an axle of said vehicle that is over said pressure sensing assemblies;(c) means for reading each of said pressure sensing elements and storing readings having a magnitude greater than a predetermined threshold, readings below said threshold corresponding to readings for a low pressure and flat tire;(d) means for comparing each said readings with a value corresponding to a non-flat tire and for displaying whether the reading is equal to or less than the value.
