RF DOPPLER BIO-SIGNAL SENSOR FOR CONTINUOUS HEART RATE VARIABILITY AND BLOOD PRESSURE MONITORING
First Claim
1. A device to measure a bodily parameter, the device comprising:
- an antenna pair including a transmit (Tx) antenna configured to transmit one or more radar pulses and a receive (Rx) antenna configured to receive the one or more radar pulses, wherein the Tx antenna and the Rx antenna are positioned so that a radar target can be positioned between the Tx antenna and the Rx antenna; and
a processor configured to;
control the Tx antenna to transmit a first radar pulse and a second radar pulse,control the Rx antenna to receive the first radar pulse and the second radar pulse, wherein the first radar pulse and the second radar pulse travel through the radar target, anddetermine a bodily parameter within the radar target as a function of the transmission and the reception of the first radar pulse and the second radar pulse.

Abstract
A method implemented by a device to measure a bodily parameter includes transmitting, by a transmit (Tx) antenna of an antenna pair, a first radar pulse to a receive (Rx) antenna of the antenna pair. The method also includes receiving, by the receive (Rx) antenna, the first radar pulse. The first radar pulse travels through a radar target between the Tx antenna and the Rx antenna. The method further includes transmitting, by the Tx antenna, a second radar pulse to the Rx antenna. In addition the method includes receiving, by the Rx antenna, the second radar pulse, wherein the second radar pulse travels through the radar target between the Tx antenna and the Rx antenna. The method also includes determining a bodily parameter within the radar target as a function of the transmission and the reception of the first radar pulse and the second radar pulse.
