Abstract: An elevator moves through a hoistway with one or more sensors positioned so that they pass by one or more targets that are in fixed positions relative to the hoistway. As they pass, an inductive current is generated, giving the elevator's control circuitry precise information as to the vertical position of the elevator car.
