Abstract
A respiration rate of a human subject is derived by: (1) receiving data corresponding to a sequence of two-dimensional pressure distributions of the human subject as applied against an array of pressure sensors over time; (2) converting the data into a one-dimensional waveform; (3) identifying oscillations in the one-dimensional waveform as occurrences of breath of the human subject; and (4) deriving the respiration rate of the human subject based on frequencies of the oscillations.
Claims17
A non-transitory computer-readable storage medium, comprising executable instructions to:
- receive data corresponding to a sequence of two-dimensional pressure distributions of a human subject as applied against an array of pressure sensors over time;
- convert the data into a one-dimensional waveform;
- identify oscillations in the one-dimensional waveform as occurrences of breath of the human subject;
- and
- derive a respiration rate of the human subject based on frequencies of the oscillations.
A non-transitory computer-readable storage medium, comprising executable instructions to:
- receive time series data corresponding to a sequence of pressure maps of a human subject as applied against a sensor sheet over time;
- identify an occurrence of non-respiratory movement of the human subject;
- omit a portion of the time series data corresponding to the occurrence of non-respiratory movement;
- identify an oscillation in a remaining portion of the time series data as an occurrence of breath of the human subject;
- and
- derive a respiration rate of the human subject based on a frequency of the oscillation.
