    摘要： A wearable apparatus for a patient for use in cough detection, comprising: a movement sensor configured to generate measurements of a movement of the patient, the movement sensor configured to be worn by the patient; a sound sensor configured to generate measurements of breathing sounds of the patient; a controller interfaced with the movement sensor and the sound sensor; and a housing for locating the movement sensor, sound sensor, and controller, wherein the controller is configured to: obtain a movement signal corresponding to the measurements of the movement of the patient made by the movement sensor; obtain a sound signal corresponding to the measurements of the breathing sounds of the patient made by the sounds sensor; generate thoracic movement data from the movement signal; generate breathing data from the sound signal; and generate respiratory data comprising the thoracic movement data and the breathing data, and further comprising correlation information configured to enable identification of contemporaneous breathing events within the thoracic movement data and the breathing data; provide correlated respiratory data to a processing module configured for identifying specific breathing events at least including coughing events, such that a coughing event is identifiable from the correlated respiratory data according to a coincidence of identification of a predefined sound pattern within the breathing data and identification of a predefined movement pattern within the thoracic movement data.

    摘要： A device and method for monitoring respiration in freely moving subjects uses measurement of changes in axial circumference during respiration to compute, store, and display respiratory rate, volume flows, and drive patterns. Since the embodiments allow a direct absolute measure of circumference throughout the respiratory cycle, they are amenable to low frequency sampling and provide an opportunity to use anthropometric scaling without resorting to concomitant spirometry. Belt sensors arranged in parallel to belt tautening forces permit independent adjustment of pre-load forces on the displacement-measuring components. The monitoring system can be used at home to facilitate a wide range of health and fitness objectives such as tracking dysfunctional breathing patterns, optimizing athletic training, and learning relaxation practices such a pranayama.

    摘要： Adaptive respiratory condition assessment can include capturing signals generated by sensors of a portable device positioned to sense a user's body. The sensors can generate the signals in response to sensor-detected movements of the user's body measured along multiple axes and corresponding to lung activity in the user's body during respiratory cycles. A preferred axis of measurement can be selected using signal processing performed by a signal processor embedded in the portable device. Waveforms generated from signals corresponding to signals generated in response to movements of the user's body measured along the preferred axis can be filtered for extracting biomarkers from the waveforms using the signal processor. The one or more biomarkers extracted correspond to the lung activity. Based on the biomarkers, a respiratory condition of the user can be determined. A notification based on the respiratory condition as determined can be generated and conveyed with the portable device.
