Abstract
A radar-based physiological motion sensor is disclosed. Doppler-shifted signals can be extracted from the signals received by the sensor. The Doppler-shifted signals can be digitized and processed subsequently to extract information related to the cardiopulmonary motion in one or more subjects. The information can include respiratory rates, heart rates, waveforms due to respiratory and cardiac activity, direction of arrival, abnormal or paradoxical breathing, etc. In various embodiments, the extracted information can be displayed on a display.
Claims28
-78. (canceled)
A method of determining the regularity of respiration, comprising:
- processing one or more frames of a respiratory waveform to obtain information regarding the irregularity or regularity of respiration;
- said respiratory waveform comprising one or more frames, wherein the one or more frames comprise time sampled values of respiratory signals;
- and
- communicating the information to an output system that is configured to perform an output action.
-129. (canceled)
A system for determining the regularity of respiration, the system comprising:
- one or more antennas configured to transmit electromagnetic radiation;
- one or more antennas configured to receive electromagnetic radiation;
- at least one processor configured to process one or more frames of a respiratory waveform to obtain information regarding the irregularity or regularity of respiration, wherein the one or more frames comprise time sampled values of respiratory signals;
- and
- a communications system configured to communicate the obtained information with an output device, said output device configured to perform an output action based on the obtained information.
