Glossary
Some of the words defined below are used to describe as-
pects of the programming of Procyon sessions in the follow-
ing Appendix.
BioConnect
2
– A serial data protocol for controlling various parame-
ters of the Artvision with biofeedback equipment, allowing for real-
time control of the system. We intend to publish this specification and
to support its use under the GNU Public License.
Clipped Waveform
– A waveform which is attempting to exceed its
maximum allowed amplitude and in consequence is
clipped
, or set
equal to the maximum possible amplitude.
Color Channel
– A single color from the three available (red, green
and blue), and all of its associated parameters. Each channel is com-
pletely independent of the others and can be set to its own frequency,
brightness, phase, etc.
DC offset
– This controls the amount of steady (ganzfeld) light is
mixed with the flicker component. A setting of 127 allows each pulse
of light to vary between completely off and completely on, while a set-
ting of 255 completely eliminates flicker. Intermediate settings gener-
ate gently pulsing or flickering output, which is generally quite pleas-
ant. Settings in the range 140 to 230 or so produce a nicely balanced
mixture of flicker and steady light.
Flash memory
– Nonvolatile memory, which may be reprogrammed.
Both the Procyon operating system and data storage utilize this type of
memory, which may be programmed and erased up to 100,000 times.
Frequency
– The number of waveform cycles per second. Also re-
ferred to in this document as
Hertz
(Hz for short). The frequency range
for the Procyon is 0.1 Hz to 75.0 Hz.
Ganzfeld
— a field of light which glows steadily, without flickering.
We’ve extended this definition to include fields of light which can
change from one hue to another.
