Abstract: A method of inducing a high efficiency conductive state at room temperature within a conductive mass (1) by injecting a complex modulated carrier signal (7) into one or more injection points (2,3) whereby the carrier signal and the subharmonic modulation frequencies (4,5,6) which are imbedded in the modulation of the carrier signal are tuned to the mass lattice qualities of the material. The amplitude and phase relationship of each individual subharmonic frequencies (4,5,6) are respectively tuned to the mass lattice qualities of the conductive mass (1). This method of excitation, with precise matching of subharmonic modulation frequencies, and with a precise matching concordant harmonic of the carrier frequency, creates an observed ionic excitation throughout the conductive mass (1) at room temperature.

Abstract: Electrically isolating the gate terminals of a pair of semiconductor output devices increases the switching speed of a solid state relay. A time delay enables tuning of the isolated gate circuits facilitating simultaneous operation of the output devices.
