Biofeedback training method and system
First Claim
1. A closed loop system for use in the biofeedback training of a subject, comprisinga. a plurality of discrete subsystems each adapted to monitor a different physiological function of said subject and generate status signals with respect thereto,b. a discrete biological sensor connected to each subsystem and adapted to be connected to said subject,c. matrix means connected to all of said subsystems for logically processing said status signals and generating a single feedback signal when at least two different selected status signals are at a predetermined value,d. sensory means for said subject connected to said matrix means and adapted to produce a sensory signal as a feedback sensory input to said subject upon generation of a feedback signal from said matrix means,e. each of said subsystems including amplifying means connected to each of said sensors for amplifying the output thereof, and analog to digital converting means connected to said amplifying means for converting analog signals from said amplifying means to digital signals for said matrix means,f. each of said subsystems including binary output means for said matrix means and said matrix means includes a logical AND gate connected to each of said subsystems and said sensory means and adapted to generate an output feedback signal only when predetermined status signals are at a predetermined value, and,g. switching means between each of said subsystems, said matrix means and said sensory means for selectively connecting any of said subsystems to either said matrix means or directly to said sensory means,h. said subsystems including a thermal module adapted to detect temperature differences between spaced points on said subject, an EMG module adapted to detect muscular activity of said subject and an EEG module adapted to detect brain wave activity of said subject,i. said thermal module including a digital differentiator for periodically sampling, storing and comparing status signals processed by said thermal module,j. said EMG module including a logarithmic converter adapted to provide a feedback signal logarithmically proportional to the status signals processed by said EMG module,k. said EEG module including a threshold digital filter providing a feedback signal only when the status signals processed by said EEG module are within a predetermined value.

Abstract
A system and method are provided for use in training individuals in biofeedback techniques. A variety of physiological functions are monitored on separate channels and associated circuitry generates feedback signals for each function. The feedback signals from the various physiological functions preferably are combined in a matrix from which an output is generated only under predetermined conditions as when two or more of the monitored functions are within the parameters set for each separate function.
