Abstract: Methods and devices provide physiological movement detection, such as gesture, breathing, cardiac and/or gross body motion, with active sound generation such as for an interactive audio device. The processor may evaluate, via a microphone coupled to the interactive audio device, a sensed audible verbal communication. 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 generated sound signal from the vicinity or user. The processor may process the reflected sound, such as by a demodulation technique, to derive a physiological movement signal. The processor may generate, in response to the sensed audible verbal communication, an output based on an evaluation of the derived physiological movement signal.

Each noise reduction component of the pair of noise reduction components includes a laminated structure that includes at least one sound-reflecting layer, and at least one sound-absorbing layer that is arranged to be closer to the ear of the user than the at least one sound-reflecting layer.

Abstract: Respiratory patient interface (e.g., mask) structures may be modified to include acoustical feature(s) (AF) to provide differences in structure that can produce, when acoustically sensed, a unique acoustic signature for identification of a particular model mask and thereby differentiate it from other model masks. The added AF may be generally similar across different models of patient interface but have detectable differences between the models. However, the added AF of a particular model are typically substantially the same for all masks of that particular model. Such AF may, for example, be a change in material composition of a section or part of a flow path of the patient interface, a change in a dimension, such as a length, of a section or part of a flow path of the patient interface, and/or an expansion and/or contraction of a section (e.g., diameter) or part of a flow path of patient interface.

Abstract: A patient interface includes a cushion assembly adapted to form a seal around the patient's nose and/or mouth and a gas washout vent configured to allow a flow of patient exhaled CO2 to an exterior of the patient interface to minimise rebreathing of exhaled CO2 by the patient.

At least one volume reducing member is provided within the plenum chamber to reduce an effective internal volume of the plenum chamber. The at least one volume reducing member is arranged to separate a main volume of the plenum chamber for delivery of the therapy pressure from deadspace volume provided at least superior the entrance to the patient's nasal passages. The main volume is adapted to be in direct fluid communication with the patient's nose and/or mouth and the vent.

Abstract: A wireless device triggers a first scheduling request (SR) in response to data of a first logical channel becoming available. A second SR is triggered in response to data of a second logical channel becoming available. When no valid SR resource is configured for the second SR: a random access procedure is initiated; and the second SR is cancelled and the first SR is keep pending. In response to the triggering of the first SR, the first SR is transmitted via a first SR resource corresponding to the first logical channel.

Abstract: A system and method is disclosed for performing diagnostics on patient devices (720). The patient devices (720) may include respiratory therapy devices that operate in accordance with instruction sets, such as software or firmware. A server (710) may maintain a database of diagnostic data (718) indicating faults in one or more of a plurality of patient devices (720). The server (710) may transmit this diagnostic data (718) to one or more computing devices (760), including identification of faults that have occurred. The server (710) may also transmit service data to the plurality of patient devices (720) in order to address the identified faults.

Abstract: A mask apparatus for a respiratory treatment can permit delivery of breathable gas to a user. In one example, the mask may employ a frame and cushion to form a seal for both mouth and nose. The frame may be adapted for coupling with a respiratory treatment apparatus so as to permit communication of a pressurized gas from the respiratory treatment apparatus. The cushion, which may be foam, may have a substantially under the nose configuration or over the nose configuration. The mask may have a common plenum chamber for both nose and mouth. The cushion may further define a centrally open lip superior region. The cushion may be adapted to couple with the frame directly or to the frame in conjunction with a cushion support clip. Various features of the cushion may further promote sealing and comfort for the under the nose design.

Abstract: Methods and apparatus provide communications among respiratory therapy device (“TD”), server and intermediary (e.g., a control device (“CTLD”) for the therapy device) to improve security. More secure communication channel(s) may be established using shared secrets derived with different channels. The communications may include transmitting therapy data from TD to server for authentication. The CTLD may receive the data and a nonce from a server. The CTLD receives from the TD a signing key dependent on the nonce and a secret shared by TD and server. The CTLD generates an authorisation code with received therapy data and the key for authentication of the data by the server upon its receipt of the code and data. The server computes (1) a key from the nonce and the secret known to TD, and (2) another authorisation code from received therapy data and the key. Data authentication may involve comparing received and computed codes.

The patient interface further includes a gas washout vent, a support structure that is attached to and is more rigid than the flexible cushion, and a pair of headgear connectors located on opposing lateral sides of the support structure.

Abstract: An exchanger conduit permits temperature and/or humidity conditioning of a gas for a patient respiratory interface. In an example embodiment, a conduit has a first channel and a second channel where the first channel is configured to conduct an inspiratory gas and the second channel configured to conduct an expiratory gas. An exchanger is positioned along the first channel and the second channel to separate the first channel and the second channel. The exchanger is configured to transfer a component (e.g., temperature or humidity) of the gas of the second channel to the gas of the first channel. In some embodiments, an optional flow resistor may be implemented to permit venting at pressures above atmospheric pressure so as to allow pressure stenting of a patient respiratory system without a substantial direct flow from a flow generator of respiratory treatment apparatus to the patient during patient expiration.
