Claim 0:
1. A system comprising:
an ultrasonic electric wave generator operative to produce electrical signals at user-selectable ultrasonic frequencies which when transduced to sound waves are known to evoke a tingling sensation on exposed human skin;
an ultrasonic electric wave amplifier operative to amplify incoming ultrasonic electric wave signals, to user-selectable power levels, wherein the amplified ultrasonic electric wave signals have essentially the same signal characteristics as said incoming ultrasonic electric wave signals, and enable a user to adjust power levels that just begin to evoke a tingling sensation when transduced to sound waves;
a multiplexor, microcontroller, adjustable phasing subsystem comprising:
a multiplexor operative to receive said amplified ultrasonic electric wave signal and multiplex said amplified ultrasonic electric wave signal into a plurality of outputs wherein each said output has essentially the same signal characteristics as said amplified ultrasonic electric wave signal; and
an adjustable phasing subsystem operative to alter phase characteristics of said plurality of outputs, under programmed control of a microcontroller, after which each individual output of said plurality of outputs is conveyed to each individual ultrasonic sound transducer in an array of ultrasonic sound transducers.
