SYSTEM AND METHOD FOR ATTACHMENT FREE MOTION, RESPIRATION, HEARTBEAT, AND VIDEO MONITORING
First Claim
1. A non-invasive monitoring system comprising:
- a pad for allowing a subject to lay on;
a sensor array comprising impulse-sensitive transducers, the sensor array configured to be integrated with said pad and to provide a time-domain composite output waveform responsive to said subject'"'"'s motion, respiration, and heart beat;
a subject agitator;
a signal processor configured to;
receive the time-domain composite output waveform;
filter the time-domain composite waveform to obtain the time-domain respiration rate signal waveform and the heart rate signal waveform;
apply a Fast Fourier Transform to the time-domain respiration rate signal waveform and the heart rate signal waveform to provide frequency-domain signal waveforms of the respiration rate and the heart rate; and
find the peak of each corresponding signal to calculate the respiration rate and the heart beat rate.

Abstract
A system and method directed to attachment free monitoring of a subject'"'"'s respiration, heartbeat, and motion. In one embodiment, the monitoring system is comprised of a monitoring pad, a base station, and a monitoring display device such as a smart phone or web interface. In another embodiment, the components of the system are communicatively coupled through wireless means. In yet another embodiment, the monitoring system additionally comprises a visual monitoring device. The monitoring pad provides the signal that is filtered to isolate various components representing the subject'"'"'s motion, respiration, and heartbeat. The system may be programmed to provide alerts and subject stimulation based on various trigger points tied to thresholds in the measurements.

16. A method of non-invasively monitoring motion, heart rate, and respiration rate of a subject comprising the steps of:
-
receiving a time-domain composite signal from a impulse-sensitive sensor array comprising impulse-sensitive transducers, the time-domain composite signal comprising a respiration rate component and a heart rate component; determining if the signal indicates an active or inactive state; filtering the time-domain composite waveform to obtain the time-domain respiration rate signal waveform and the heart rate signal waveform; applying a Fast Fourier Transform function to the time-domain respiration rate signal waveform and the heart rate signal waveform to provide frequency-domain signal waveforms of the respiration rate and the heart beat rate; and finding the peak of each corresponding signal to calculate the respiration rate and the heart beat rate. - View Dependent Claims (17, 18, 19, 20)
