MONITORING BREATHING VIA SIGNAL STRENGTH IN WIRELESS NETWORKS

摘要

Systems and methods are disclosed for the use of sensor links in a network to estimate the breathing rate of a breathing subject within a structure, estimate the location of the subject within the structure, and detect if the subject is breathing. The structure may be a bed, a building, or a room in the building. The received signal strength of the sensor links is obtained and is then used in various breathing models to determine the breathing rate estimation, the location estimation, and the breathing detection.

主权项

1. A method for breathing rate estimation comprising:
arranging a plurality of sensors in a network around a subject within a structure; measuring received signal strengths (RSS) between the plurality of sensors, wherein the measured RSS is at least partially indicative of breathing of the subject; determining a breathing rate estimation model based on information related to the measured signal strengths; and estimating a breathing rate of the subject using the breathing rate estimation model.
