explaining Sharp's VOICE TO SKULL success

Above image shows the start of the article, with the
very important statement about the August 1974 public
announcement of the successful transmission of pulsed
microwave voice to skull at the University of Utah.

Above image gives the description of the successful
modulation. Note that the fidelity of current-day
voice to skull transmission is much higher after three-
plus decades of apparent development.

Above image illustrates the modulation method used by
Dr. Joseph Sharp for the first known successful transmission
of voice to skull using pulsed microwave. No implants are
required for this form of V2S transmission, and this form of
transmission will penetrate non-conducting walls. Image below
shows a simple circuit which can duplicate Sharp's modulation
method.

Above image shows a simple 555 timer chip circuit which can
duplicate Joseph Sharp's original modulation method. When
output to a loudspeaker, voice and music are recognizable.
