Abstract
An object moves along a predetermined route adjacent a pair of inductive radio lines crossed at two predetermined intervals P.sub.1 and P.sub.2. A sensing device on the object senses the intervals and enables generation of an object position signal having a first code value when the interval P.sub.1 is sensed and a second code value when the interval P.sub.2 is sensed.
