Embodiment Construction

[0052] 1 System overview

[0053] see figure 1 , the vital signs monitoring system 100 monitors the vital signs (eg, breathing rate and heart rate) of the one or more subjects 102a, 102b without requiring any physical contact between the one or more subjects and the vital signs monitoring system 100 touch. Vital signs monitoring system 100 includes transmit antenna 104 , receive antenna 106 and signal processing subsystem 108 . It should be noted that in some examples, system 100 includes multiple receive antennas and / or multiple transmit antennas, rather than having a single receive antenna and a single transmit antenna. However, to simplify the description of the vital sign monitoring system, the following description only refers to the single receive antenna / single transmit antenna embodiment.

[0054] In general, vital signs monitoring system 100 transmits low power wireless signals from transmit antenna 104 into the environment surrounding system 100 . The transmitt...

Abstract

A method for monitoring periodic motions of one or more subjects uses signal reflections from the subjects. The method includes emitting a transmitted signal from a transmitting antenna and receiving a received signal at one or more receiving antennas. The received signal includes a combination of a number of reflections of the transmitted signal, at least some of which are associated with the subjects. The received signal, including the reflections, is processed to determine an estimate of a fundamental frequency of the periodic motions.
