Superimposing Method & Apparatus Useful for Subliminal Messages
Willson, Joseph
Abstract --- Data to be displayed is combined with a composite video signal. The
data is stored in a memory in digital form. Each byte of the data is read out in
sequential fashion to determine: the recurrence display rate of the data according
to the frame sync pulses of the video signal; the location of the data within the
video image according to the line sync pulses of the video signal; and the
location of the data display within the video image according to the position
information. Synchronization of the data with the video image is derived from the
sync pulses of the composite video signal. A similar technique is employed to
combine sound data with an audio signal. Data to be displayed may be presented as
a subliminal message or may persist for a given time interval. The data may be
derived from a variety of sources including a prerecorded or live video signal.
The message may be a reminder message displayed upon a television screen to remind
the viewer of an appointment. The data may be stored in a variety of different
memory devices capable of high speed data retrieval. The data may be generated
locally on-line or off-line and transferred to memory which stores the data
necessary to create the message.

Product Detector for a Steady Visual Evoked Potential Stimulator and Product
Detector
Abstract --- An automated visual testing system is disclosed which presents an
alternating steady state visual stimulus to a patient through an optical system
that modifies the stimulus image. As the image changes, the patient produces
evoked potentials that change. The evoked potentials are detected by a product
detector which produces the amplitude of the evoked potentials. The product
detector includes filters which isolate the patient's evoked potentials, a
modulator which detects the response using the stimulus source frequency and a
demodulator that determines the amplitude of the response. The product detector
detects the level of the steady state evoked potential signals even in the
presence of substantial background noise and extraneous electroencephalograhic
signals. These detectors can be used to monitor the evoked potential produced by
visual, aural or somatic steady state stimuli. The components described above can
be used to produce a system that can determine to which of several different
displays an observer is paying attention by providing images that blink at
different frequencies and product detectors for each of the stimulus frequencies.
The product detector producing the highest output indicates the display upon which
the observer is focused.

Method & Apparatus for Translating the EEG into Music...
Knispel, Joel, et al.
Abstract --- A method and apparatus for applying a musical feedback signal to the
human brain, or any other brain, to induce controllable psychological and
physiological responses. A signal representing the ongoing electroencephalographic
(EEG) signal of a brain preferably is obtained from the electrode location on the
scalp known as CZ or P3 in clinical notation. A signal processor converts the
ongoing EEG into electrical signals which are converted into music by
synthesizers. The music is acoustically fed back to the brain after a time delay
calculated to shift the phase of the feedback in order to reinforce specific or
desired ongoing EEG activity from the scalp position of interest. The music is
comprised of at least one voice that follows the moment-by-moment contour of the
EEG in real time to reinforce the desired EEG activity. The music drives the brain
into resonance with the music to provide a closed loop or physiological feedback
effect. Preferably, the musical feedback comprises additional voices that embody
psychoacoustic principles as well as provide the content and direction normally
supplied by the therapist in conventional biofeedback. The invention contemplates
numerous applications for the results obtained.

Auditory Subliminal Programming System
Schultz, Richard M., et al.
Abstract --- An auditory subliminal programming system includes a subliminal
message encoder that generates fixed frequency security tones and combines them
with a subliminal message signal to produce an encoded subliminal message signal
which is recorded on audio tape or the like. A corresponding subliminal
decoder/mixer is connected as part of a user's conventional stereo system and
receives as inputs an audio program selected by the user and the encoded
subliminal message. The decoder/mixer filters the security tones, if present, from
the subliminal message and combines the message signals with selected low

a composite auditory subliminal signal. The decoder/mixer combines the composite
subliminal signal with the selected audio program signals to form composite
signals only if it detects the presence of the security tones in the subliminal
message signal. The decoder/mixer outputs the composite signal to the audio inputs
of a conventional audio amplifier where it is amplified and broadcast by
conventional audio speakers.

Shevrin, Howard, et al.
Abstract --- A system for assessing psychobiological conditions of a subject
utilizes a plurality of words which are selected to be in four categories as
critical stimuli. The words are presented by a tachistoscope to the subject in
subliminal and supraliminal modes of operation. Subliminal stimulation of the
subject is achieved by presenting the selected words for an exposure period of
approximately one millisecond. The supraliminal exposure time is approximately
thirty milliseconds. Prior to stimulation, the subject is diagnosed in accordance
with conventional psychoanalytical techniques to establish the presence and nature
of a pathological condition. The words are selected and categorized in four
groups: pleasant words, unpleasant words, words related to a diagnosed conscious
pathological condition, and words related to a diagnosed unconscious pathological
condition. The brain wave responses which are evoked by the stimulation are
collected via electrodes and analyzed in accordance with a transinformation
technique which is based on information signal theory for establishing a
probabilistic value which corresponds to the information content of the evoked
responses.

Shadow Generating Apparatus
Whitten, Glen, et al.
Abstract --- Disclosed is an apparatus for inducing various brain wave patterns
through visual stimulation. The apparatus comprises a pair of spectacles or other
viewing apparatus having a liquid crystal display embedded in each lens. By
repetitively activating and deactivating the liquid crystals, shadows are
generated which are perceived by the subject individual wearing the viewing
apparatus. Responding to the frequency of shadow generation, the subject's brain
is thereby induced to generate sympathetic brain wave frequencies. The apparatus
finds particular utility in the generation of alpha waves. Because learning is
enhanced when the brain is in the alpha state, activities such as listening to
tapes or lectures and the like can be carried out with greater facility. Shadow
generation is accomplished through the use of a timing mechanism for each liquid
crystal display and the frequency for each is adjustable over a wide range,
permitting synchronous or asynchronous timing.

Auditory Subliminal Message System & Method
Lundy, Rene R., et al.
Abstract --- Ambient audio signals from the customer shopping area within a store
are sensed and fed to a signal processing circuit that produces a control signal
which varies with variations in the amplitude of the sensed audio signals. A
control circuit adjusts the amplitude of an auditory subliminal anti-shoplifting
message to increase with increasing amplitudes of sensed audio signals and
decrease with decreasing amplitudes of sensed audio signals. This amplitude
controlled subliminal message may be mixed with background music and transmitted
to the shopping area. To reduce distortion of the subliminal message, its
amplitude is controlled to increase at a first rate slower than the rate of
increase of the amplitude of ambient audio signals from the area. Also, the
amplitude of the subliminal message is controlled to decrease at a second rate
faster than the first rate with decreasing ambient audio signal amplitudes to
minimize the possibility of the subliminal message becoming supraliminal upon
rapid declines in ambient audio signal amplitudes in the area. A masking signal is
provided with an amplitude which is also controlled in response to the amplitude
of sensed ambient audio signals. This masking signal may be combined with the
auditory subliminal message to provide a composite signal fed to, and controlled
by, the control circuit.

Method & Apparatus for Repetitively Producing a Noise-like Audible Signal
Nagle, William L.
Abstract --- A digital pulse generator and shift register repetitively produce
bursts of digital pulses at a first adjustable repetition frequency. The
repetition frequency of the pulses in each burst is also adjustable. A pink noise
filter accentuates the lower burst frequency components near 7 hz and
substantially attenuates all frequency components of the bursts above a first cutoff
point near 10 Khz. A tunable band pass amplifier having a center frequency
adjustable over a preselected range of frequencies optimally detectable by the
average human ear accentuates the pink noise filter output near 2.6 Khz. The
tunable amplifier drives an audible signal source with noise-like pulses of
varying amplitudes and frequency components. A low pass amplifier may be connected
to the pink noise filter to generate a train of pulses having a repetition
frequency near 7 hz which pulses a light source in synchronism with the audible
noise-like signal.

with the goal of achieving the desired condition of its nervous system. Responding
to the stimulus, the organism can be trained to control the waveform patterns of
the monitored bioelectrical signals and thereby, control its own nervous system.
The results of the coincidence function permit results heretofore unobtainable.

Hearing Aid for Producing Sensations in the Brain
Zink, Henry R.
Abstract --- A pulsed oscillator or transmitter supplies energy to a pair of
insulated electrodes mounted on a person's neck. The transmitter produces pulses
of intensity greater than a predetermined threshold value and of a width and rate
so as to produce the sensation of hearing without use of the auditory canal,
thereby producing a hearing system enabling otherwise deaf people to hear.

Electronic System for Stimulation of Biological Systems
Lenskes, H.
Abstract --- A receiver totally implanted within a living body is inductively
coupled by two associated receiving coils to a physically unattached external
transmitter which transmits two signals of different frequencies to the receiver
via two associated transmitting coils. One of the signals from the transmitter
provides the implanted receiver with precise control or stimulating signals which
are demodulated and processed in a signal processor network in the receiver and
then used by the body for stimulation of a nerve, for example, while the other
signal provides the receiver with a continuous wave power signal which is
rectified in the receiver to provide a source of electrical operating power for
the receiver circuitry without need for an implanted battery.

Method & Apparatus for Producing Swept FM Audio Signal Patterns for Inducing Sleep
Zentmeyer, J.
Abstract --- A method of producing sound signals for inducing sleep in a human
being, and apparatus therefor together with REPRESENTATIONS thereof in recorded
form, wherein an audio signal is generated representing a familiar, pleasing,
repetitive sound, modulated by continuously sweeping frequencies in two selected
frequency ranges having the dominant frequencies which occur in electrical wave
patterns of the human brain during certain states of sleep. The volume of the
audio signal is adjusted to mask the ambient noise and the subject can select any
of several familiar, repetitive sounds most pleasing to him.

Hearing Systems
Puharich, Henry K.
Abstract --- The present invention relates to the stimulation of the sensation of
hearing in persons of impaired hearing abilities or in certain cases persons
totally deaf utilizing RF energy. More particularly, the present invention relates
to a method and apparatus for imparting synchronous AF or ""acoustic" signals and
so-called "transdermal" or RF signals. Hearing and improved speech discrimination,
in accordance with one aspect of the present invention, is stimulated by the
application of an AF acoustical signal to the "ear system" conventional
biomechanism of hearing, which is delivered to the brain through the "normal"
channels of hearing and a separate transdermal RF electrical signal which is
applied to the "facial nerve system" and is detectable as a sensation of hearing.
Vastly improved and enhanced hearing may be achieved...
