Wireless physiology monitor
First Claim
1. A method for physiology monitoring of a living subject, the method implemented at a physiology monitoring device and comprising the steps of:
- transmitting, at the physiology monitoring device, a signal comprising an IEEE 802.11(x) orthogonal frequency-division multiplexing (OFDM) signal,receiving, at the physiology monitoring device, a modified signal, wherein the modified signal comprises IEEE 802.11(x) OFDM signal after having interacted with the living subject, andprocessing, via circuitry at the physiology monitoring device, the modified signal to monitor a physiological function of a moving organ of the living subject, wherein the step of processing comprises the steps of;
mixing the received modified signal with the IEEE 802.11(x) OFDM signal to form a mixed signal,filtering the mixed signal to extract physiological information pertaining to the moving organ, andanalyzing the extracted physiological information to monitor the physiological function of the moving organ.

Abstract
The present invention provides a new non-invasive technique for organ, e.g., heart and lung, monitoring. In at least one embodiment of the invention, a subject is radiated with a non-harmful and relatively low power electromagnetic source diagnostic signal normally associated with a communications protocol such as, but not limited to a version of the IEEE 802.11(x) family of protocols in the 2.4, 3.6, or 5 GHz spectrum bands. After passing through the patient, a return signal is acquired from the patient and compared to the original source signal. The differences between the source and modified signals are then analyzed to monitor the heart, e.g., measure heart rate and detect defects within the heart, and the lung. For example, using Doppler Effect principles, heart rate and motion can be measured from the differences in frequency, phase, and/or wavelength between the source signal and the modified signal reflected back from the heart moving within the patient.
