  • Flat tire sensor
    Patent number: 6094979
    Abstract: An apparatus and method of detecting the presence of a flat tire on a vehicle. A pair of spaced apart pressure sensing assemblies positioned on a roadway are operative to produce a signal corresponding to the pressure applied to one or more pressure sensing elements in each of the pressure sensing assemblies. Comparison of the pressure applied to each of the pressure sensing elements with a value corresponding to a normal non-flat tire indicates the condition of the tires.
