Abstract: Methods and apparatus provide monitoring of coughing and/or a sleep disordered breathing state of a person. One or more sensors may be configured for non-contact active and/or passive sensing. The processor(s) may extract respiratory effort signal(s) from one or more motion signals generated by active non-contact sensing with the sensor(s). The processor(s) may extract one or more energy band signals from an acoustic audio signal generated by passive non-contact sensing with the sensor(s). The processor(s) may assess the energy band signal(s) and/or the respiratory efforts signal(s) to generate intensity signal(s) representing sleep disorder breathing modulation. The processor(s) may classify feature(s) derived from the one or more intensity signals to generate measure(s) of coughing and/or sleep disordered breathing. The processor may evaluate sensing signal(s) to generate indication(s) of cough event(s) and/or cough type which may include generating an indication of a coronavirus disease or a coronavirus disease cough type.

The method including determining physiological parameter(s) from at least a first portion of the sensor data acquired during a test session. The method including associating the determined physiological parameter(s) with the testing session. The method including authenticating the device by i) determining identification data using at least a second portion of the sensor data, the identification data including identifiable characteristic(s) of the one or more digits; ii) accessing authentication data that includes one or more authentication characteristics; and iii) comparing the identification data with the authentication data to determine a match to authenticate the device. The method including generating a chain of custody determination based at least in part on the authentication of the device.

Abstract: Methods and devices provide physiological movement detection with active sound generation. In some versions, a processor may detect breathing and/or gross body motion. The processor may control producing, via a speaker coupled to the processor, a sound signal in a user's vicinity. The processor may control sensing, via a microphone coupled to the processor, a reflected sound signal. This reflected sound signal is a reflection of the sound signal from the user. The processor may process the reflected sound, such as by a demodulation technique. The processor may detect breathing from the processed reflected sound signal. The sound signal may be produced as a series of tone pairs in a frame of slots or as a phase-continuous repeated waveform having changing frequencies (e.g., triangular or ramp sawtooth). Evaluation of detected movement information may determine sleep states or scoring, fatigue indications, subject recognition, chronic disease monitoring/prediction, and other output parameters.

Abstract: A method of determining a sleep stage of an individual comprises identifying features associated with a current epoch of the sleep session, determining a plurality of sleep stage probabilities based on the features, identifying events experienced by the individual during the current epoch, and adjusting each of the plurality of sleep stage probabilities based on events experienced by the individual during the current epoch or a prior epoch, and/or a sleep stage previously determined for the prior epoch. The features include at least one feature associated with a flow of pressurized air from a respiratory therapy system used by the individual, at least one feature associated with a respiration rate of the individual, and/or at least one feature associated with a time of the sleep session. Each sleep stage probability corresponds to a respective one of a plurality of potential sleep stages during the current epoch of the sleep session.

Abstract: A method includes providing a tag applied to an intended test subject. The tag having an anti-tamper authentication feature that is altered when the tag is removed from the test subject, and which, when altered, is rendered unsuitable for authentication. The method including providing a diagnostic device applied to a test subject. The diagnostic device interacting with the anti-tamper authentication feature of the tag. The method including authenticating the tag with the diagnostic wearable device based on the diagnostic device's interaction with the anti-tamper authentication feature. Successful authentication indicating that the test subject is the intended test subject. Unsuccessful authentication occurring when the anti-tamper authentication feature is altered. The method including collecting sensor data from the test subject via the diagnostic device. The method also including associating the collected sensor data with the intended test subject using the authentication of the tag with the diagnostic device.

Abstract: A method includes receiving, at a user device, first sensor data from sensor(s) coupled to the user device. The method including receiving identity enrollment information associated with a test subject engaging in a testing session and establishing a communication link between the user device and a wearable diagnostic device.

The method including receiving second sensor data from the wearable diagnostic device after the first time. The method including analyzing the second sensor data to identify an interference instance indicative that the wearable diagnostic device is no longer worn by the test subject at a second time. The method including generating a chain of custody determination based at least in part on the interference instance.

Abstract: Various implementations of the present disclosure are directed to systems and methods for leak detection in a respiratory therapy system using acoustic data. According to some implementations, a method includes receiving acoustic data associated with airflow caused by operation of a respiratory therapy system during a sleep session of a user. The method also includes analyzing at least a portion of the acoustic data to determine a value of a parameter associated with the at least a portion of the acoustic data. The method further includes determining an occurrence of a leak during the sleep session in response to the determined value of the parameter satisfying a condition.
