    This LAYS TO REST ANY DOUBTS THAT VOICE TO SKULL
    TECHNOLOGY DOES NOT EXIST OR IS "IN THE FUTURE"!
    PERIOD!

    This article describes in precise terms how Dr. Joseph C.
    Sharp and staff transmitted the WORDS for the digits 1 to 10
    using a modulated version of an Allan Frey type pulsed
    microwave transmitter.  A detailed description of Frey
    transmitters can be viewed at:

    The demonstration of sonic transduction of microwave energy
    by materials lacking in water LESSENS the likelihood that a
    thermohydraulic principle is operating in human perception
    of the energy.  Nonetheless, some form of thermoacoustic
    transduction probably underlies perception.  If so, it is
    clear that simple heating is NOT a sufficient basis for the
    Frey effect; the requirement for pulsing of radiations
    appears to implicate a thermodynamic principle.

    Frey and Messenger (1973) and Guy, Chou, Lin, and Christen-
    sen (1975) confirmed that a microwave pulse with a slow rise
    time is INeffective in producing an auditory response; only
    if the rise time is SHORT, resulting in effect in a square
    wave with respect to the leading edge of the envelope of
    radiated radio-frequency energy, does the auditory response
    occur.
