Abstract: A means and method of controlling a plurality of energy beams with at least one of the plurality of beams. At least one first beam set produces special interference with at least one second beam set, at a first location(s), diverting energy from both beam sets to a second location(s), where energy does not appear from one . . . or either, of the inputs in the absence of interference. By selecting the timing, levels, phases, frequencies, and interconnection of multiple controllers, a multitude of useful energy beam circuits are able to be made . . . such as: gated amplifiers, cascaded amplifiers, gated oscillators, phase demodulators, active filters, inverters, inverted filters, limiters, threshold detectors . . .
