Abstract:
1. A method of monitoring health by physiological monitoring of body motion using a non-invasive sensor comprising: creating a first array of data using a processor based on discretely recorded body motion events detected by the sensor in which each element of the first array is representative of a time when a body motion event took place; creating a second array of data using a processor in which each element of the second array is an interval representative of the difference between successive elements of the first array; creating a third array of data using a processor in which each element of the third array is a delta interval representative of the difference between successive elements of the second array; performing a fast Fourier transform (FFT) on the third array using a processor to obtain power spectrum data representative of the third array; integrating the power spectrum data over frequency ranges of interest using a processor to obtain discrete power values for said frequency ranges of interest; and displaying the power spectrum data and discrete power values using a display device to monitor health.
