Abstract:
1. A system for measuring a weight upon a seating surface of a seat having a bracket, said system comprising: at least one ferromagnetic element mechanically coupled between the bracket and a vehicle floor such that strain is induced in said at least one ferromagnetic element responsive to the weight thereon; a fastener extending between the bracket and the floor; and a first sensor comprising (i) a magnet generating a magnetic field magnetically coupled to the at least one ferromagnetic element on a first side of the fastener and (ii) an inductor magnetically coupled to the at least one ferromagnetic element on a second side of the fastener opposite the first side, said magnet and inductor mounted adjacent said ferromagnetic element, said magnetic field altered by said strain in said ferromagnetic element, said inductor generating a signal based upon the alteration in said magnetic field.
