Abstract
An elevator speed and positioning device includes an elongated member and a rotating disk. The elongated member includes an apparatus for indicating position along the member and the disk includes an apparatus for communicating the indicating apparatus. A constant relationship exists between the elongated member and the disk such that relative positions between the two are repeatable. The relative motion between the elongated member and the disk may be quantified to determine the relative position of the elevator car.
