Abstract
A system and method for monitoring a person within a defined area by detecting breathing, or the lack thereof. Breathing is detected using radar signals, camera signals and/or microphone signals. The radar signals, camera signals and/or microphone signals are analyzed to determine if the subject person is moving, and if not moving if the person is breathing or not-breathing. An alarm is generated should the reflected radar signals, the camera signals and the microphone signals all simultaneously indicate no movement and no movement of the subject person in the defined area for a selected period of time.
Claims20
A method for distinguishing, using radar, a patient in a monitored area, the method comprising:
- receiving reflected radar signals corresponding to radar signals transmitted toward the monitored area;
- partitioning radar samples based on the reflected radar signals into a plurality of range bins corresponding to different ranges in the monitored area;
- for the range bins, generating respective binary representations by applying at least one threshold associated with a patient to the radar samples, wherein the at least one threshold is set to digitize each range bin by assigning a first binary value to radar sample values above the threshold and a second binary value to radar sample values below the threshold;
- comparing the binary representations among the range bins to identify a first correlated set of range bins associated with the patient;
- and
- determining at least one movement of the patient based at least in part on the radar samples of the first correlated set and at least one selection metric derived from the radar samples.
A system for distinguishing, using radar, a patient in a monitored area, the system comprising:
- at least one processor configured to execute instructions, wherein upon execution, the instructions cause the system to:
- receive reflected radar signals corresponding to radar signals transmitted toward the monitored area;
- partition radar samples based on the reflected radar signals into a plurality of range bins corresponding to different ranges in the monitored area;
- for the range bins, generate respective binary representations by applying at least one threshold associated with a patient to the radar samples, wherein the at least one threshold is set to digitize each range bin by assigning a first binary value to radar sample values above the threshold and a second binary value to radar sample values below the threshold;
- compare the binary representations among the range bins to identify a first correlated set of range bins associated with the patient;
- and
- determine at least one movement of the patient based at least in part on the radar samples of the first correlated set and at least one selection metric derived from the radar samples.
