<p>Electronically controlled coil assembly for use in electrical and electronic applications such as tuned circuits, transformers, and devices which require or utilize a moving magnetic field. The coil assembly comprises a plurality of electrical conductors carried by a substrate with electronically controlled elements for controlling the windings which are energized or connected into a circuit. Embodiments are disclosed in which the coil assembly is constructed both in printed circuit form and in microminiature form.</p> |
