US 2020/0345274 A1 · SYSTEMS AND METHODS FOR MONITORING RESPIRATION AND MOTION

Abstract

Systems and methods for remotely sensing movement of a mammalian subject utilize a radio frequency (RF) transmitter configured to impinge a RF signal on tissue of a mammalian subject, a RF receiver configured to receive a reflected RF signal, a processor configured to separately identify presence of respiratory and non-respiratory motion of the mammalian subject, and a memory configured to store processes signal values generated by or derived from the processor, wherein the processor is configured to compare one or more processed signals against one or more stored processed signal values, and detect a health state or health condition of the mammalian subject. Sleep apnea and respiratory events may be detected. In one embodiment, motion of a human infant may be mapped over time, and motion trends may be used to assess proper development of the infant.

Dependent claims

A system for remotely sensing movement of a mammalian subject, the system comprising:

a radio frequency (RF) transmitter configured to transmit a RF signal for impingement on tissue of the mammalian subject;
a RF receiver configured to receive a RF signal comprising a reflection of the RF signal impinged on tissue of the mammalian subject;
at least one processor configured to process the received RF signal to separately identify presence of respiratory motion of the mammalian subject and presence of non-respiratory motion of the mammalian subject;
and
a memory configured to store processed signal values generated by or derived from the at least one processor indicative of at least one of (i) respiratory motion of the mammalian subject or (ii) non-respiratory motion of the mammalian subject;
wherein the at least one processor is further configured to compare one or more processed signals generated by or derived from the at least one processor against one or more stored processed signal values, and detect at least one health state or health condition of the mammalian subject.

A method for detecting at least one health state or health condition of a mammalian subject, the method comprising:

transmitting a radio frequency (RF) signal to impinge on tissue of the mammalian subject;
receiving a RF signal comprising a reflection of the RF signal impinged on tissue of the mammalian subject;
processing the received RF signal utilizing at least one processor to separately identify presence of respiratory motion of the mammalian subject and presence of non-respiratory motion of the mammalian subject;
storing processed signal values generated by or derived from the at least one processor in a memory, the processed signal values being indicative of at least one of (i) respiratory motion of the mammalian subject or (ii) non-respiratory motion of the mammalian subject;
and
utilizing the at least one processor, comparing one or more processed signals generated by or derived from the at least one processor against one or more stored processed signal values, and responsive to the comparing, detecting at least one health state or health condition of the mammalian subject.
