**USP # 6,506,148 (January 14, 2003)**
  
**Nervous
System Manipulation by EM Fields from Monitors**
  
**Loos, Hendricus**   
**Abstract
---**Physiological effects have been observed in a
human subject in response to stimulation of the skin with
weak electromagnetic fields that are pulsed with certain
frequencies near 1/2 Hz or 2.4 Hz, such as to excite a
sensory resonance. Many computer monitors and TV tubes,
when displaying pulsed images, emit pulsed electromagnetic
fields of sufficient amplitudes to cause such excitation.
It is therefore possible to manipulate the nervous system
of a subject by pulsing images displayed on a nearby
computer monitor or TV set. For the latter, the image
pulsing may be imbedded in the program material, or it may
be overlaid by modulating a video stream, either as an RF
signal or as a video signal. The image displayed on a
computer monitor may be pulsed effectively by a simple
computer program. For certain monitors, pulsed
electromagnetic fields capable of exciting sensory
resonances in nearby subjects may be generated even as the
displayed images are pulsed with subliminal intensity.

**USP # 6,488,617 (December 3, 2002)**   
**Method and Device for Producing a Desired Brain State**   
**Katz, Bruce**   
**Abstract
---** A method and device for the
production of a desired brain state in an individual contain
means for monitoring and analyzing the brain state while a set
of one or more magnets produce fields that alter this state. A
computational system alters various parameters of the magnetic
fields in order to close the gap between the actual and
desired brain state. This feedback process operates
continuously until the gap is minimized and/or removed.

binary counter, and a speaker that generates a humanly audible
sound from the third low voltage audio power amplifier.

**USP # 6,292,688 (September 18, 2001)**   
**Method and Apparatus for Analyzing Neurological Response to
Emotion-Inducing Stimuli**   
**Patton, Richard**   
**Abstract
---** A method of determining the
extent of the emotional response of a test subject to stimului
having a time-varying visual content, for example, an
advertising presentation. The test subject is positioned to
observe the presentation for a given duration, and a path of
communication is established between the subject and a brain
wave detector/analyzer. The intensity component of each of at
least two different brain wave frequencies is measured during
the exposure, and each frequency is associated with a
particular emotion. While the subject views the presentation,
periodic variations in the intensity component of the brain
waves of each of the particular frequencies selected is
measured. The change rates in the intensity at regular periods
during the duration are also measured. The intensity change
rates are then used to construct a graph of plural coordinate
points, and these coordinate points graphically establish the
composite emotional reaction of the subject as the
presentation continues.

**USP # 6,258,022 (July 10,2001)**   
**Behavior Modification**   
**Rose, John**   
**Abstract
---** Behavior modification of a human
subject takes place under hypnosis, when the subject is in a
relaxed state. A machine plays back a video or audio
recording, during which the subject is instructed to activate
a device to create a perceptible stimulation which is linked,
through the hypnosis, with a visualization of enhanced or
improved performance. After the hypnosis, the user can
reactivate the device at will, whenever the improved
performance, such as an improved sporting performance, is
desired. This will again create the perceptible stimulation
and thus induce the required visualization.

**USP # 6,239,705 (May 29,2001)**   
**Intra-Oral Electronic Tracking Device**   
**Glen, Jeffrey**   
**Abstract
---** An improved stealthy,
non-surgical, biocompatable electronic tracking device is
provided in which a housing is placed intraorally. The housing
contains microcircuitry. The microcircuitry comprises a
receiver, a passive mode to active mode activator, a signal
decoder for determining positional fix, a transmitter, an
antenna, and a power supply. Optionally, an amplifier may be
utilized to boost signal strength. The power supply energizes
the receiver. Upon receiving a coded activating signal, the
positional fix signal decoder is energized, determining a
positional fix. The transmitter subsequently transmits through
the antenna a position locating signal to be received by a
remote locator. In another embodiment of the present
invention, the microcircuitry comprises a receiver, a passive
mode to active mode activator, a transmitter, an antenna and a
power supply. Optionally, an amplifier may be utilized to
boost signal strength. The power supply energizes the
receiver. Upon receiving a coded activating signal, the
transmitter is energized. The transmitter subsequently
transmits through the antenna a homing signal to be received
by a remote locator.

**USP #
6,167,304 (December 26, 2000)**   
**Pulse Variability in
Electric Field Manipulation of Nervous Systems**
  
**Loos, Hendricus**
  
**Abstract
---** Apparatus and method for manipulating the
nervous system of a subject by applying to the skin a
pulsing external electric field which, although too weak to
cause classical nerve stimulation, modulates the normal
spontaneous spiking patterns of certain kinds of afferent
nerves. For certain pulse frequencies the electric field
stimulation can excite in the nervous system resonances with
observable physiological consequences. Pulse variability is
introduced for the purpose of thwarting habituation of the
nervous system to the repetitive stimulation, or to
alleviate the need for precise tuning to a resonance
frequency, or to control pathological oscillatory neural
activities such as tremors or seizures. Pulse generators
with stochastic and deterministic pulse variability are
disclosed, and the output of an effective generator of the
latter type is characterized.

Harmonious States of Being**   
**Bowman, Gerard D., *et
al.***   
**Abstract
---** A method of inducing harmonious states of being
using vibrational stimuli, preferably sound, comprised of a
multitude of frequencies expressing a specific pattern of
relationship. Two base signals are modulated by a set of
ratios to generate a plurality of harmonics. The harmonics
are combined to form a "fractal" arrangement.

**USP # 6,122,322 (September 19, 2000)**   
**Subliminal Message Protection**   
**Jandel, Magnus**   
**Abstract
---** The present invention relates to
a method and to a system for detecting a first context change
between two frames. When a second context change between a
further two frames occurs within a predetermined time
interval, the frames accommodated within the two context
changes are defined as a subliminal message. An alarm is sent
to an observer upon detection of a subliminal message.

**USP #
6,091,994  (July 18, 2000)**   
**Pulsative Manipulation
of Nervous Systems**   
**Loos, Hendricus**
  
**Abstract
---** Method and apparatus for manipulating the
nervous system by imparting subliminal pulsative cooling to
the subject's skin at a frequency that is suitable for the
excitation of a sensory resonance. At present, two major
sensory resonances are known, with frequencies near 1/2 Hz
and 2.4 Hz. The 1/2 Hz sensory resonance causes relaxation,
sleepiness, ptosis of the eyelids, a tonic smile, a "knot"
in the stomach, or sexual excitement, depending on the
precise frequency used. The 2.4 Hz resonance causes the
slowing of certain cortical activities, and is characterized
by a large increase of the time needed to silently count
backward from 100 to 60, with the eyes closed. The invention
can be used by the general public for inducing relaxation,
sleep, or sexual excitement, and clinically for the control
and perhaps a treatment of tremors, seizures, and autonomic
system disorders such as panic attacks. Embodiments shown
are a pulsed fan to impart subliminal cooling pulses to the
subject's skin, and a silent device which induces
periodically varying flow past the subject's skin, the flow
being induced by pulsative rising warm air plumes that are
caused by a thin resistive wire which is periodically heated
by electric current pulses.

**USP #
6,081,744  (June 27, 2000)**   
**Electric Fringe Field
Generator for Manipulating Nervous Systems**   
**Loos, Hendricus**
  
**Abstract
---** Apparatus and method for manipulating the
nervous system of a subject through afferent nerves,
modulated by externally applied weak fluctuating electric
fields, tuned to certain frequencies such as to excite a
resonance in neural circuits. Depending on the frequency
chosen, excitation of such resonances causes in a human
subject relaxation, sleepiness, sexual excitement, or the
slowing of certain cortical processes. The electric field
used for stimulation of the subject is induced by a pair of
field electrodes charged to opposite polarity and placed
such that the subject is entirely outside the space between
the field electrodes. Such configuration allows for very
compact devices where the field electrodes and a
battery-powered voltage generator are contained in a small
casing, such as a powder box. The stimulation by the weak
external electric field relies on frequency modulation of
spontaneous spiking patterns of afferent nerves. The method
and apparatus can be used by the general public as an aid to
relaxation, sleep, or arousal, and clinically for the
control and perhaps the treatment of tremors and seizures,
and disorders of the autonomic nervous system, such as panic
attacks.

**USP # 6,052,336 (April 18, 2000)**   
**Apparatus and Method of Broadcasting Audible Sound Using
Ultrasonic Sound as a Carrier**   
**Lowrey, Austin, III**   
**Abstract
---** An ultrasonic sound source
broadcasts an ultrasonic signal which is amplitude and/or
frequency modulated with an information input signal
originating from an information input source. If the signals
are amplitude modulated, a square root function of the
information input signal is produced prior to modulation. The
modulated signal, which may be amplified, is then broadcast
via a projector unit, whereupon an individual or group of
individuals located in the broadcast region detect the audible
sound.

**USP # 6,039,688 (March 21, 2000)**   
**Therapeutic Behavior Modification Program, Compliance
Monitoring and Feedback System**   
**Douglas, Peter, et al.**   
**Abstract
---** A therapeutic behavior
modification program, compliance monitoring and feedback
system includes a server-based relational database and one or
more microprocessors electronically coupled to the server. The
system enables development of a therapeutic behavior
modification program having a series of milestones for an
individual to achieve lifestyle changes necessary to maintain
his or her health or recover from ailments or medical
procedures. The program may be modified by a physician or
trained case advisor prior to implementation. The system
monitors the individual's compliance with the program by
prompting the individual to enter health-related data,
correlating the individual's entered data with the milestones
in the behavior modification program and generating compliance
data indicative of the individual's progress toward
achievement of the program milestones. The system also
includes an integrated system of graphical system interfaces
for motivating the individual to comply with the program.
Through the interfaces, the individual can access the database
to review the compliance data and obtain health information
from a remote source such as selected sites on the Internet.
The system also provides an electronic calendar integrated
with the behavior modification program for signaling the
individual to take action pursuant to the behavior
modification program in which the calendar accesses the
relational database and integrates requirements of the program
with the individual's daily schedule, and an electronic
journal for enabling the individual to enter personal
health-related information into the system on a regular basis.
In addition, the system includes an electronic meeting room
for linking the individual to a plurality of other individuals
having related behavior modification programs for facilitating
group peer support sessions for compliance with the program.
The system enables motivational media presentations to be made
to the individuals in the electronic meeting room as part of
the group support session to facilitate interactive group
discussion about the presentations. The entire system is
designed around a community of support motif including a
graphical electronic navigator operable by the individual to
control the microprocessor for accessing different parts of
the system.

**USP #
6,017,302  (January 25, 2000)**   
**Subliminal Acoustic
Manipulation of Nervous Systems**   
**Loos, Hendricus**
  
**Abstract
---** In human subjects, sensory resonances can be
excited by subliminal atmospheric acoustic pulses that are
tuned to the resonance frequency. The 1/2 Hz sensory
resonance affects the autonomic nervous system and may cause
relaxation, drowsiness, or sexual excitement, depending on
the precise acoustic frequency near 1/2 Hz used. The effects
of the 2.5 Hz resonance include slowing of certain cortical
processes, sleepiness, and disorientation. For these effects
to occur, the acoustic intensity must lie in a certain
deeply subliminal range. Suitable apparatus consists of a
portable battery-powered source of weak subaudio acoustic
radiation. The method and apparatus can be used by the
general public as an aid to relaxation, sleep, or sexual
arousal, and clinically for the control and perhaps
treatment of insomnia, tremors, epileptic seizures, and
anxiety disorders. There is further application as a
nonlethal weapon that can be used in law enforcement
standoff situations, for causing drowsiness and
disorientation in targeted subjects. It is then preferable
to use venting acoustic monopoles in the form of a device
that inhales and exhales air with subaudio frequency.

**USP # 6,011,991 (January 4, 2000)**
  
**Communication
System
& Method Including Brain Wave Analysis...**
  
**Mardirossian, Aris**   
**Abstract ---** A system and method for
enabling human beings to communicate by way of their
monitored brain activity. The brain activity of an
individual is monitored and transmitted to a remote
location (e.g. by satellite). At the remote location, the
monitored brain activity is compared with pre-recorded
normalized brain activity curves, waveforms, or patterns
to determine if a match or substantial match is found. If
such a match is found, then the computer at the remote
location determines that the individual was attempting to
communicate the word, phrase, or thought corresponding to
the matched stored normalized signal.

**USP # 6,006,188 (December 21, 1999)**   
**Speech Signal Processing for Determining Psychological or
Physiological Characteristics...**   
**Bogdashevsky, Rostislav, et al.**   
**Abstract
---** A speech-based system for
assessing the psychological, physiological, or other
characteristics of a test subject is described. The system
includes a knowledge base that stores one or more speech
models, where each speech model corresponds to a
characteristic of a group of reference subjects. Signal
processing circuitry, which may be implemented in hardware,
software and/or firmware, compares the test speech parameters
of a test subject with the speech models. In one embodiment,
each speech model is represented by a statistical time-ordered
series of frequency representations of the speech of the
reference subjects. The speech model is independent of a
priori knowledge of style parameters associated with the voice
or speech. The system includes speech parameterization
circuitry for generating the test parameters in response to
the test subject's speech. This circuitry includes speech
acquisition circuitry, which may be located remotely from the
knowledge base. The system further includes output circuitry
for outputting at least one indicator of a characteristic in
response to the comparison performed by the signal processing
circuitry. The characteristic may be time-varying, in which
case the output circuitry outputs the characteristic in a
time-varying manner. The output circuitry also may output a
ranking of each output characteristic. In one embodiment, one
or more characteristics may indicate the degree of sincerity
of the test subject, where the degree of sincerity may vary
with time. The system may also be employed to determine the
effectiveness of treatment for a psychological or
physiological disorder by comparing psychological or
physiological characteristics, respectively, before and after
treatment.

**USP # 5,954,630 (September 21, 1999)**   
**FM Theta-Inducing Audible Sound...**   
**Masaki, Kazumi, et al.**   
**Abstract
---** An audible sound of modulated
wave where a very low-frequency wave of about 20 hertz or
lower is superposed on an audio low-frequency wave effectively
stimulates Fm theta in human brain waves to improve attention
and concentration during mental tasks when auditorily
administered. The audible sound is also effective in
stimulation of human alpha wave when the very low-frequency
wave lies within the range of about 2-10 hertz. Such audible
sound is artificially obtainable by generating an electric
signal which contains such a modulated wave, and transducing
it into audible sound wave.

One of the first and second band-pass filters is selected, and
a stimulation signal is produced in dependency on an .alpha.
wave extracted by a selected band-pass filter. In accordance
with the stimulation signal, a stimulation light is emitted to
the user in order to induce the user to relax or sleeping
state.

stimulation and diagnostics of auditory nerves of a human
being, e.g. for determination of sensation level (SL), most
conformable level (MCL) and uncomfortable level (UCL)
audibility curves, includes a stimulator detachably secured to
a human being for sending a signal into a human ear, and an
electrode placed within the human ear and electrically
connected to the stimulator by an electric conductor for
conducting the signals from the stimulator into the ear. A
control unit is operatively connected to the stimulator for
instructing the stimulator as to characteristics of the
generated signals being transmitted to the ear.

**USP # 5,868,103 (February 9, 1999)**   
**Method and Apparatus for Controlling an Animal**   
**Boyd, Randal**   
**Abstract
---** An apparatus for controlling an
animal wherein the animal receives a control stimulus of the
release of a substance having an adverse effect upon the
animal as a corrective measure. The apparatus includes a
transmitter for producing a transmitted field, and a
releasable collar for attaching to the neck of the animal. The
collar includes a receiver for receiving the transmitted field
and for producing a received signal, a control circuit for
determining when the received signal indicates that the animal
requires a corrective measure and for producing a control
signal, a container for containing the substance having an
adverse effect upon the animal, and a mechanism for releasing
the substance from the container into the presence of the
animal upon the production of the control signal by the
control circuit. In use, the transmitter is set to produce the
transmitted field and the collar is attached to the neck of
the animal. As the animal moves about, the receiver in the
collar receives the transmitted field and produces a received
signal. The control circuit determines when the received
signal indicates that the animal requires a corrective
measure. A control signal is produced by the control circuit
when the determination is made that the animal requires a
corrective measure. Upon the production of the control signal,
the substance having an adverse effect upon the animal is
released from the container and into the presence of the
animal.

5,784,124 (July 21, 1998)**   
**Supraliminal Method of
Education...**   
**D'Alitalia, Joseph A., *et 
al.***   
**Abstract
---** A method of behavior modification involves
having a patient view supraliminal video messages
superimposed upon an underlying video presentation. The
video messages incorporate messages wherein at least some of
the messages link a desired modified behavior to positive
feelings of the patient. A supraliminal message generator
and superimposer iteratively selects individual messages for
display from the sequence of messages, decompressing the
messages as required, and places the selected messages in a
buffer memory of a video generation device. A processor of
the supraliminal message generator and superimposer then
fades the selected message from an invisible level to a
visible level on the video display, and then fades the
selected message from the visible level back to the
invisible level.

**USP # 5,649,061 (July 15, 1997)**   
**Device and Method for Estimating a Mental Decision**   
**Smyth, Christopher**   
**Abstract
---** A device and method for
estimating a mental decision to select a visual cue from the
viewer's eye fixation and corresponding single event evoked
cerebral potential. The device comprises an eyetracker, an
electronic biosignal processor and a digital computer. The
eyetracker determines the instantaneous viewing direction from
oculometric measurements and a head position and orientation
sensor. The electronic processor continually estimates the
cerebral electroencephalogramic potential from scalp surface
measurements following corrections for electrooculogramic,
electromyogramic and electrocardiogramic artifacts. The
digital computer analyzes the viewing direction data for a
fixation and then extracts the corresponding single event
evoked cerebral potential. The fixation properties, such as
duration, start and end pupil sizes, end state (saccade or
blink) and gaze fixation count, and the parametric
representation of the evoked potential are all inputs to an
artificial neural network for outputting an estimate of the
selection interest in the gaze point of regard. The artificial
neural network is trained off-line prior to application to
represent the mental decisions of the viewer. The device can
be used to control computerized machinery from a video display
by ocular gaze point of regard alone, by determining which
visual cue the viewer is looking at and then using the
estimation of the task-related selection as a selector switch.

**Woith, Blake F.**   
**Abstract
---** A subliminal recording includes
both subliminal message and mask signals applied to both
tracks of a two track recording medium. The subliminal message
signals are identical in content, and are recorded in an

phase. The resulting recording may be utilized in the
conventional manner for subliminal recordings. By combining
the composite signals in an inverted relationship, the mask
signals cancel while the subliminal message signals are
additive, thus allowing the presence of the subliminal message
signal to be confirmed on the recording.

**Method and Apparatus for Introducing Subliminal Changes to
Audio Stimuli**   
**Lauffer, Martha A., et al.**   
**Abstract
---** A method and apparatus for
introducing gradual changes to an audio signal so that the
changes are subliminal. The changes can involve tempo and
volume, for example, and can take the form of a gentle
gradient having ever increasing/decreasing ramp-like changes
over a sufficient duration, or a more complex program
involving several gentle gradients. In the preferred
embodiment, an enhanced audio play-back device such as a
portable audio cassette recorder can be programmed to
subliminally alter the characteristics of a standard
pre-recorded tape containing music, for example. As a
motivational tool during walking, jogging or other repetitive
exercise, the tempo is gradually increased over a period of
time to encourage a corresponding gradual (and subliminal)
increase in physical exertion by a user whose rate of movement
is proportional to the tempo of the music. The tempo can be
either manually changed in conjunction with a subliminal
program, or by itself in an override mode, or by itself in a
version of the present-inventive audio play-back device which
allows only manual tempo alternation. In an alternate
embodiment, a special pre-recorded tape contains subliminal
changes in tempo, for example, for play-back on a standard
audio cassette recorder (which operates at one speed, only) to
cause the same effect as the preferred embodiment.

**Method for Mixing Audio Subliminal Recordings**   
**Taylor, Eldon, et al.**   
**Abstract
---** Audio subliminal recordings are
made in which in addition to using a primary carrier, such as
music, two audio channels are used to deliver subliminal
messages to the brain. On one channel, accessing the left
brain hemisphere, the message delivered is meaningfully
spoken, forward-masked, permissive affirmations delivered in a
round-robin manner by a male voice, a female voice and a
child's voice. On the other channel, accessing the right
brain, directive messages, in the same voices, are recorded in
backward-masked (or meta-contrast). The three voices are
recording in round-robin fashion with full echo reverberation.
The audio tracks are mixed using a special processor which
converts sound frequencies to electrical impulses and tracks
the subliminal message to synchronize the subliminal message
in stereo with the primary carrier. The processor maintains
constant gain differential between the primary carrier and the
subliminal verbiage and, with the subliminal verbiage being
recorded with round-robin, full echo reverberation, ensures
that none of a message is lost. The primary carrier should be
continuous music without breaks or great differences in
movements.

**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

**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.

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.

**Method & Apparatus
for Generating Subliminal Visual Messages**   
**Crawford, James R., *et
al*.**   
**Abstract
---** A system for generating a subliminal message
during the display of a normal television program on a
television receiver utilizes a personal computer to generate
an RF carrier modulated with video signals encoding the
subliminal message. The computer runs under the control of
an application program which stores the subliminal message
and also controls the computer to cause it to generate
timing signals that are provided to a single pole
double-throw switch. The source of the normal television
program and the video output of the computer are connected
to the two switch inputs and the switch output is connected
to the television receiver antenna system. The timing
signals cause the switch to normally display the
conventional television program and to periodically switch
to the computer output to generate the subliminal message.
The video output of the computer includes horizontal and
vertical synchronizing signals which are of substantially
the same frequency as the synchronizing signals incorporated
within the normal program source but of an arbitrary phase.

**Method
for
Stimulating the Falling Asleep and/or Relaxing Behavior
of a Person**   
**Warnke, Egon F.**   
**Abstract ---** A method and apparatus
is provided with which a person suffering from sleeplessness
can be more easily relaxed and may more rapidly fall asleep.
In particular, sound pulses are emitted by an electro-acoustic
transducer, according to the cadence of which, the person
seeking to fall asleep is induced to breathe in and out over a
predetermined period of time. By suitably selecting the pulse
sequence frequency, the pitch and the amplitude of the sound
pulses may be adjusted thereby enhancing the process of
falling asleep.

**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.

**Abstract
---** Brain wave patterns associated with relaxd and
meditative states in a subject are gradually induced without
deleterious chemical or neurological side effects. A white
noise generator (11) has the spectral noise density of its
output signal modulated in a manner similar to the brain
wave patterns by a switching transistor within a spetrum
modulator and converted to an audio signal by acoustic
transducer. Ramp generator gradually increases the voltage
received by and resultant output frequency of voltage
controlled oscillator whereby switching transistor 
periodically shunts the high frequency components of the

**Abstract
---** Apparatus for the electrophysiological
stimulation of a patient is provided for creating an
analgesic condition in the patient to induce sleep, treat
psychosomatic disorders, and to aid in the induction of
electrohypnosis and altered states of consciousness. The
foregoing is achieved by repetitive stimuli in the patient
for whom external influences, namely those of sight and
sound, are intentionally excluded. The apparatus produces
electrical stimulation of the patient in the form of a
modulated wave which produces impulses in the delta, theta,
alpha and beta regions of the brain's electrical activity,
the electrical stimulation being accompanied by two sources
of audio stimulation, one of which is a sinusoidal tone
modulated by and synchronized with the electrical
stimulation, and the other is derived from sound recordings.

**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 cut-off 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.

**Ross, Sidney A.**   
**Abstract ---** A novel method for
controlling the nervous system of a living organism for
therapeutic and research purposes, among other applications,
and an electronic system utilized in, and enabling the
practice of, the invented method. Bioelectrical signals
generated in specifictopological areas of the organism's
nervous system, typically areas of the brain, are processed by
the invented system so as to produce a sensory stimulus if the
system detects the presence or absence, as the case may be, of
certain characteristics in the waveform patterns of the
bioelectrical signals being monitored. The coincidence of the
same or different characteristics in two or more waveform
patterns, or the non-coincidence thereof, may be correlated
with a certain desired condition of the organism's nervous
system; likewise, with respect to the coincidence or
non-coincidence of different characteristics of a single
waveform pattern. In any event, the sensory stimulus provided
by the invented system, typically an audio or visual stimulus,
or combination thereof, is fed back to the organism which
associates its presence 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.

of sensing brain waves at a position remote from a subject
whereby electromagnetic signals of different frequencies
are simultaneously transmitted to the brain of the subject
in which the signals interfere with one another to yield a
waveform which is modulated by the subject's brain waves.
The interference waveform which is representative of the

receiver where it is demodulated and amplified. The
demodulated waveform is then displayed for visual viewing
and routed to a computer for further processing and
analysis. The demodulated waveform also can be used to
produce a compensating signal which is transmitted back to
the brain to effect a desired change in electrical
activity therein.
