Physiological coherence in animals
First Claim
1. A method for detecting physiological coherence in an animal subject comprising the acts of:
- sampling a physiological measure of the animal subject;
deriving a power spectrum distribution (PSD) from the physiological measure;
tracking dynamically a PSD peak within a predetermined range where the PSD peak has a relative amplitude to a plurality of other peaks in the PSD;
determining a current coherence value based on said relative amplitude and corresponding to the animal subject'"'"'s autonomic nervous system (ANS) activity;
determining a current coherence category for the animal subject from a plurality of coherence categories which corresponds to the current coherence value; and
providing a coherence category indication associated with the current coherence category.

Abstract
A coherence value or category for an animal subject is calculated, and a corresponding coherence indication is provided to a human subject. In one embodiment, the beat-to-beat changes in the animal subject'"'"'s heart rate is monitored, and used to calculate a coherence value, which may be representative of a coherence category. The coherence value may be determined by the power distribution of the heart rate variability data for the animal subject. In another embodiment, the degree of synchronization between an animal subject'"'"'s coherence and an associated human subject'"'"'s coherence may be determined and provided as feedback.

9. A system for detecting physiological coherence in an animal subject comprising:
-
a sensor adapted to sample a physiological measure of an animal subject;
a coherence indicator configured to provide at least one of a visual and audible indication; and

17. A method for detecting a physiological coherence shift in an animal subject comprising the acts of:
-
sampling, at a first time, a physiological measure of the animal subject;
generating a heart rate variability (HRV) waveform based on said sampling at the first time, wherein the HRV waveform has a first pattern;
sampling, at a second time, the physiological measure of the animal subject;
updating the HRV waveform based on said sampling at the second time, wherein the HRV waveform has a second pattern;
comparing the first pattern to the second pattern to detect a coherence change in the animal subject;
providing a coherence indication associated with said coherence change. - View Dependent Claims (18, 19, 20, 21, 22)
