Method and system for monitoring breathing activity of an infant
First Claim
Patent Images
1. A method of monitoring breathing activity, comprising:
- measuring a first set of signal data representative of a breathing movement of an infant during a first time period;
pattern matching the first set of signal data with a second set of signal data related to measured breathing movement of the infant during a second time period to identify degree of deviation from periodicity of the breathing movement; and
reporting irregularity based upon results of the pattern matching.

Abstract
A method and system for monitoring breathing movement of an infant is disclosed. A method and system for detecting and predictably estimating regular cycles of breathing movements is disclosed. Another disclosed aspect of the invention is directed to detect and report irregularity of breathing activity of an infant, such as cessation and non-periodicity, which suggests a likelihood of SIDS.

18. A method of monitoring breathing activity, comprising:
-
measuring a set of signal data representative of a breathing movement during a time period;
comparing amplitude of the set of signal data with a threshold; and
reporting irregularity based upon results of the comparison. - View Dependent Claims (19, 20, 21, 22, 23)

24. A method of monitoring breathing activity, comprising:
-
acquiring image data;
determining a number of markers visible in the image data;
determination if the number of markers meets a threshold value; and
reporting irregularity if the number of markers does not meet the threshold value. - View Dependent Claims (25, 26, 27, 28, 29, 30, 31)

32. A method of monitoring breathing activity, comprising:
-
receiving a set of signal data representative of a breathing movement of an infant;
estimating phase of the set of signal data;
comparing a vector of the set of signal data with one or more prior sets of signal data to identify deviation from periodicity of the breathing movement, the vector of the set of signal data based upon the phase, the one or more prior sets relating to measured breathing movement of the infant during one or more prior time periods; and
reporting irregularity based upon results of the comparison. - View Dependent Claims (33, 34, 35, 36, 37, 38, 39, 40, 41, 42, 43, 44, 45)

46. A method for monitoring regular activity, comprising:
-
co-locating a marker block with an object such that movement of the marker block relates to movement of the object, the marker block comprising one or more markers;
viewing the marker block with a camera;
generating image data representative of the marker block; and
reporting irregularity based upon insufficient periodicity for detected movement. - View Dependent Claims (47, 48, 49, 50, 51, 52, 53, 54, 55, 56)
