The DAVID PALTM
is an extremely portable audio-visual entrainment (AVE) device. This is the one
that will fit in your shirt or jacket pocket (approximate dimensions: 7 x 2.5 x
9cm) and will allow you to experience AVE wherever you go. Perfect for people
who are on the go.

Tru-Vu OmniscreenTM
Eyesets - Our unique Tru-Vu OmniscreenTM Eyesets were carefully designed to provide you
with the most effective and safe light and sound experience. The Tru-Vu
OmniscreenTM Eyesets for
the PAL use eight blue-tinted white LEDs mounted over a silver reflector
behind a translucent screen. This disperses the light evenly. Our new
Tru-Vu OmniscreenTM
Eyesets are specially designed to allow for the left and right visual fields
of each eye to be individually stimulated rather than the entire eye. With
the Tru-Vu OmniscreenTM
Eyesets, the lights flash into the left visual fields of both eyes, then
alternately flashes into the right visual fields of both eyes. This approach
allows the ability to stimulate either visual cortex with a frequency
different from the other visual cortex. For example, a person who functions
strongly from the left brain could have 8 Hz stimulated into the right
visual field (and therefore the left brain) to slow down left brain function
and have 18 Hz stimulated into the left visual field to increase right brain
function.

Isochronic Pulsed Tones,
Binaural Beats and Chime - The tones of the
DAVID PALTM
are evenly spaced, are of equal pitch and are turned on and off
at a specified rate. This is important to enhance the effectiveness of audio
entrainment.
-
Soft-OffTM - The gradual
lowering of the lights and tones at the end of the session prevents a
startle response (also known as somnatic shock). Soft-OffTM
ensures that relaxation and other benefits carry over even after a session has
ended.
-
Battery Power Indicator -
At a quick glance you can tell if your battery has enough power to run your
session. New eyeset technology allows for much longer life for your
9-volt battery.
-
Easy-To-Find
Intensity and Volume Buttons
- The intensity and volume buttons are raised so that you can make the
necessary adjustments easily and quickly, even with your eyes closed. Adjust
the intensity of the OmniscreenTM Eyeset with the easy-to-find INT button.

The heart speeds up with every breath in and
slows down with every breath out. This swing in heart rate is HRV. A typical
heart beat swing is in the order of about 15 beats per minute (bpm). When people
get stressed, the heart typically clamps to sometimes as low as five bpm HRV at
times intermixed with sharp spikes in heart rate. This is all abnormal activity
and is rough on the heart.
The HRV technique used clinically is based on
a 10 second breathing cycle (six breaths/minute, by inhaling slowly for five
seconds and exhaling slowly for five seconds in an easy, relaxed breath). When
using HRV paced breathing, listen to the heartbeat generated by the DAVID PALTM through the headphones. Inhale for two
heartbeats and exhale for two heartbeats (not your own heartbeats!). Most
sessions begin at seven breathing cycles/minute (28 heartbeats/min) and slow to
six breaths /minute (24 heartbeats/min). This allows the user to breathe a
little faster at the onset of a session until he/she has had time to relax.
