Patent ID: 7780596

Claim:
A non-invasive health monitor device for physiological monitoring of body motion to obtain a measure of variability comprising: a processor; a processor readable storage medium; code recorded in the processor readable storage medium to create a first array of body motion events based on discretely recorded body motions in which each element of the first array is representative of a time when a body motion event took place; code recorded in the processor readable storage medium to create a body motion period interval array in which each element is a body motion interval representative of the difference between successive elements of the first array of body motion events; code recorded in the processor readable storage medium to create a delta body motion period interval array in which each element is a delta body motion period interval representative of the difference between successive elements of the body motion period interval array; code recorded in the processor readable storage medium to perform a fast fourier transform (FFT) to obtain power spectrum data representative of the delta body motion period interval array; and code recorded in the processor readable storage medium to integrate the power spectrum data over frequency ranges of interest to obtain discrete power values for said frequency ranges of interest.
