    Abstract: Method and apparatus obtain information about a patient and / or a respiratory therapy system that is configured to deliver respiratory therapy to the patient. The respiratory therapy system may include a flow generator configured to generate a supply of pressurized air along an air circuit to a patient interface. A sound signal representing a sound in the air circuit may be processed to obtain cepstrum data. A time series of delay estimates based on acoustic signatures of the cepstrum data may be generated. Each acoustic signature may represent a reflection of sound from a patient interface along the air circuit. Variation in the time series of delay estimates may be analysed. One or more output indicators based on the variation may be generated. The one or more output indicators may concern patient and/or system status.

    Abstract: A method for delivering a substance into an airway of a user via a respiratory system comprises receiving the substance within a receptacle; receiving physiological data; determining one or more sleep-related parameters based on the physiological data; and modifying the delivery of the substance into the airway of the user based at least in part on the one or more sleep-related parameters. The respiratory system includes a respiratory device configured to supply pressurized air to the airway of the user via a conduit and a user interface. The respiratory device, the user interface, and the conduit form an air pathway. The respiratory device is configured to include or engage the receptacle such that an outlet of the receptacle is in direct or indirect fluid communication with the air pathway.

    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 translation: 方法和设备提供主动声音生成的生理运动检测。 在一些版本中，处理器可以检测呼吸和/或粗体动作。 处理器可以控制经由耦合到处理器的扬声器在用户附近产生声音信号。 处理器可以经由耦合到处理器的麦克风来控制感测反射声音信号。 该反射的声音信号是来自用户的声音信号的反映。 处理器可以例如通过解调技术来处理反射的声音。 处理器可以从处理后的反射声音信号中检测呼吸。 声音信号可以作为一系列时隙帧中的一系列音调对产生，或者作为具有变化频率的相位连续重复波形（例如三角形或斜坡锯齿形）产生。 对检测到的运动信息的评估可以确定睡眠状态或评分，疲劳指示，受试者识别，慢性疾病监测/预测以及其他输出参数。
