There is no mindcontrol, yeah, right!
But do you know what I believe? Those silent mindcontroller
psychiatric systems are around since a very long time, courtesy of the
SEGNPMSS.
The reason why they allow Americans to file now patents hereto is
because they know since the Internet that the cat is out of the bag
anyhow, and before they take the blame of manipulating minds of people
with silent sounds, they let Americans have it. Should they be blamed
and hated for it.

Silent subliminal presentation system
Abstract
A silent communications system in which nonaural carriers, in the very
low or very high audio frequency range or in the adjacent ultrasonic
frequency spectrum, are amplitude or frequency modulated with the
desired intelligence and propagated acoustically or vibrationally, for
inducement into the brain, typically through the use of loudspeakers,
earphones or piezoelectric transducers. The modulated carriers may be
transmitted directly in real time or may be conveniently recorded and
stored on mechanical, magnetic or optical media for delayed or
repeated transmission to the listener.

Description
--------------------------------------------------------------------------------
BACKGROUND--FIELD OF THE INVENTION
This invention relates in general to electronic audio signal
processing and, in particular, to subliminal presentation techniques.
BACKGROUND--DESCRIPTION OF PRIOR ART
Subliminal learning enjoys wide use today and subliminal tapes are
being manufactured by a number of companies in the United States
alone. Several decades of scientific study indicate that subliminal
messages can influence a human's attitudes and behavior. Subliminal,
in these discussions, can be defined as "below the threshold of
audibility to the conscious mind." To be effective however, the
subliminally transmitted information (called affirmations by those in
the profession) must be presented to the listener's ear in such a
fashion that they can be perceived and "decoded" by the listener's
subconscious mind. We are referring to audio information in this
discussion, however, information could be inputted into the subject's
subconscious mind through any of the body's sensors, such as touch,
smell, sight or hearing. As an example, early development work in the
subliminal field utilized motion pictures and slide projections as the
medium. Early research into visual and auditory subliminal stimulation
effects is exemplified by U.S. Pat. Nos. 3,060,795 of Corrigan, et al.
and 3,278,676 of Becker. U.S. Pat. No. 4,395,600 of Lundy and Tyler is
representative of later developments in today's subliminal message
techniques.
The majority of the audio subliminal tapes available today are
prepared using one basic technique. That is, the verbal affirmations
are mixed with, and recorded at a lower level than, a "foreground" of
music or sounds of ocean surf or a bubbling mountain brook or other
similar "masking" sounds. The affirmations are generally recorded 5
decibels (db) or so below the "foreground" programming and
regenerative automatic gain control is usually applied to permit the
affirmations to change their recorded amplitude in direct proportion
to the short term averaged amplitude of the continually varying
"foreground" material. In other words, the volume of the affirmations
will follow or track the volume changes of the "foreground"
programming, but at a lower volume level. Circuit provisions are also
usually included to "gate" the affirmations off when the music
amplitude is low or zero. This insures that the affirmations cannot be
heard during quiet program periods. Thus, today's subliminal
affirmations can be characterized as being "masked" by music or other
sounds, of constantly changing amplitude and of being reduced or cut
off entirely during periods of low or quiet "foreground" programming.
One of the principal, and most widely objected to, deficiencies in
available subliminal tape presentation techniques is that the presence
of the "foreground" material is intrusive to both the listener and to
anyone else in the immediate area. No matter what "foreground"
material is chosen, the fact remains that this material can be heard
by anyone within its range and presents a definite distraction to
other activities such as conversation, thought, desire to listen to
other programming such as radio or television, need to concentrate,
etc. Additionally, and because the tapes are used repeatedly by the
same listener, any "foreground" music or material eventually becomes
monotonously tiring to that listener.
It is the purpose of the following described invention to eliminate or
greatly reduce all of the above deficiencies. Although its application
to the magnetic tape medium is described in the following discussion,
the technique is equally applicable to most other desired transmission
mediums, such as Compact Disc, videocassettes, digital tape recorders,
Public Address (PA) systems, background music installations, computer
software programs, random access memory (RAM), read only memory (ROM),
"live", real time applications and other mediums now in existence or
to be developed in the future.
Implemented on tape cassettes, for example, the subliminal
presentation described here is inaudible i.e., high audio or
ultrasonic frequencies, the affirmations are presented at a constant,
high amplitude level, and they occupy their own "clear channel",
non-masked frequency allocations. If desired, the previously described
"foreground" music or other material can be added to the tape through
use of an audio mixer. The "silent" recordings are inaudible to the
user or by others present and are therefore very effective for use
during periods of sleep or when in the presence of others.
Additionally, the basic requirements of subliminal stimulation are
met. That is, the affirmations are efficiently transmitted to the ear
and, while undetected by the conscious mind, are perceived by and
efficiently decoded by the subconscious mind.
OBJECTS OF THE INVENTION
Accordingly, several objects and advantages of my invention are:
(a) to provide a technique for producing a subliminal presentation
which is inaudible to the listeners(s), yet is perceived and
demodulated (decoded) by the ear for use by the subconscious mind.
(b) to provide a technique for transmitting inaudible subliminal
information to the listener(s) at a constant, high level of signal
strength and on a clear band of frequencies.
(c) to provide a technique for producing inaudible subliminal
presentations to which music or other "foreground" programming may be
added, if desired.
Still further objects and advantages will become apparent from a
consideration of the ensuing description and drawings.

DETAILED DESCRIPTION OF A PREFERRED EMBODIMENT
Please refer now to FIG. 1 and FIG. 2, which are drawings of a
preferred implementation of the invention.
The principle of operation of the silent subliminal presentation
system is as follows:
An audio signal in the upper frequency region of the audio spectrum
(for example, 14,500 Hz) is modulated with the desired information.
The type of modulation may be any type suitable for subliminal
applications; frequency modulation (FM), phase modulation (PM), upper
single sideband with suppressed carrier, amplitude modulation (AM),
tone modulation, etc.
For broadest application, the high audio frequency selected as the
carrier frequency must meet two basic criteria:
(1) be high enough in the audio spectrum that its presence to the
human ear is essentially unnoticed or undetectable (without the
listener being informed that the signal is actually present) and,
(2) be low enough in the audio spectrum that it (and its modulation
content) can produce a useful output power from home entertainment
type cassette or reel-to-reel magnetic recorders.
This would also include, of course, small portable and automobile tape
decks.
Alternatively, the output of the system can be fed directly into an
audio amplifier and its speaker/earphone system, Public Address
system, etc.
FIG. 1 provides the block diagram of an example of a system capable of
generating the desired silent frequency modulated carrier.
The modulation information is inputted into the microphone 11. Other
suitable input devices may be substituted for microphone 11, such as a
tape recorder or a radio. The microphone 11 is connected to the
preamplifier 12 and should have provisions for adjusting its gain in
order that the optimum modulation index can be set in the frequency
modulator 13. The frequency modulator 13 modulates the frequency of
oscillator 14 which has been adjusted for an output of 14,500 Hz as
described above. The output of oscillator 14 is fed through a suitable
bandpass filter 15 into the tape recorder or directly into a suitable
amplifier/speaker system. It is the purpose of the bandpass filter to
remove or attenuate audible products of the modulation process in
order to maintain as audibly silent an output as practical.
On the receiving end, FIG. 2 represents an approximate and idealized
frequency response curve of the human ear. The frequency modulated
carrier (centered at 14,500 Hz), as generated above and played through
a tape recorder or amplifier/speaker system, is shown on FIG. 2 as
speaker output 26, impinging upon the upper slope of the ear's
response curve at point 25. The frequency modulated excursions of the
speaker output 26 swing between points 23 and 24 on the ear's upper
response curve. Because the response curve between points 23 and 25 is
relatively linear, this action results in a relatively linear
demodulation of the original modulation intelligence, which is passed
on subliminally to the inner ear. The amplitude of the demodulated
output is not high enough to be detected by the conscious mind but is
sufficient in amplitude to be detected by the subconscious mind. In
the field of communications engineering design, the above demodulation
process in known as slope detection and was used in early FM receiver
design. In those receivers, the response curve was formed by the
action of a tuned (inductive/capacitance) circuit. In our case, the
response curve is formed by the natural response curve of the human
ear. The same slope detection technique can be performed at the low
frequency end of the human ear response curve. This region is
indicated on FIG. 2 as between points 21 and 22. This region, however,
has a much smaller available bandwidth and is therefore more
restricted as to the amount of information that can be transmitted in
an inaudible manner.
In practice, the listener adjusts the volume control of the tape
recorder or amplifier to a level just below that at which the listener
hears an audible sound or noise from the speaker of the tape recorder.
If the recording process is properly done, a spectrum analyzer or a
calibrated sound level meter will reveal a strong signal emanating
from the tape recorder speaker. A calibrated sound level meter, at a
distance of 1 meter (with C weighting and referenced to the standard
of 0.0002 micro bar) will typically indicate a silent power output of
from 60 to 70 decibels. This is equivalent to the audio power of a
loud conversation, yet, in the described system, is inaudible or
unnoticed by the listener.
FIG. 3 illustrates a system which generates a suitable amplitude
modulated (AM) signal, instead of the frequency modulated (FM) system
described above. The output is a modulated, single sideband (SSB),
suppressed carrier (AM) signal at 14,500 Hz.
The block diagram represents a common scheme for generating an SSB
signal and will be briefly described.
The desired subliminal information is spoken into microphone 31. This
signal is amplified by speech amplifier 32 and injected into one port
of balanced modulator 33. A continuous wave signal of 455 KHz is
generated by carrier oscillator 34 and is injected into the second
port of balanced modulator 33. The output of balanced modulator 33 is
a double sideband, suppressed carrier signal at 455 KHz. This signal
is fed through filter 35, causing one of the two sidebands to be
removed. This signal is fed into one port of mixer 36. A continuous
wave signal at a frequency of 469.5 KHz from hetrodyne oscillator 37
is fed into the other port of mixer 36, resulting in an output of the
original subliminal audio information but translated 14,500 Hz higher
in frequency. The bandpass filter 38 attenuates signals and noise
outside of the frequencies of interest. The amplitude modulated audio
output signal is shown as output 39.
Thus, as stated earlier, my invention provides a new system for
subliminal presentations which is:
(a) silent,
(b) outputs a constant, high level modulated signal and,
(c) occupies a band of clear channel frequencies.
The foregoing description of the preferred embodiment of the invention
has been presented for the purposes of illustration and description.
It is not intended to be exhaustive or to limit the invention to the
precise form disclosed. Many modifications and variations are possible
in light of the above discussions. It is intended that the scope of
the invention be limited not only by this detailed description, but
rather by the claims appended hereto.
