DEFINITION

Classification: 318/660

(under subclass 652) Subject matter in which the particular position measuring instrument is an "Inductosyn". An "Inductosyn" is a rotary or linear synchro-like device in which the rotor and stator windings move relative to each other in parallel planes. Included herein are devices in which the rotor and stator windings are printed circuits.
