Abstract: A system and method for managing a respiratory condition of a user is disclosed. The system includes an oxygen concentrator having a compression system configured to generate oxygen enriched air for delivery to the user. A physiological sensor is configured to collect physiological data of the user. The physiological data is of one or more data types. An operational sensor is configured to collect operational data of the oxygen concentrator during operation of the oxygen concentrator. The operational data is of one or more data types. A processor is configured to receive the collected physiological data and the operational data and compute a summary parameter for values of each data type. The processor is also configured to compute a health score from the summary parameter values.

Abstract: The invention concerns a novel mesh structure with high resistance in particular to piercing and tearing.The object of the invention is a novel mesh structure with high resistance in particular to piercing and to tearing, characterized in that it comprises a knit structure, the texture of which is formed of an entirety of forward meshes comprising a quilting stitch, two cylindrical reverses and a flat weft, repeated every eight drops, with the threads constituting the knit being formed of polyaramide fibers.The invention is useful in the fashioning of clothing, linings or walls for protective and/or safety purposes.

Abstract: The invention concerns a novel composite product based on filament or fiber reinforcements, in particular in the woven or knit form, wound upon itself or in concentric layers.The object of the invention is a novel composite product characterized in that it comprises a reinforcement or fabric comprising at least one lap wound upon itself or a plurality of tubular laps placed concentrically, and reinforcing filaments or fibers inserted between at least some of the successive layers of the lap or laps, parallel to the axis of the wound or concentric structure and transverse to the latter, the entire assembly being molded into a bonding matrix.Possible applications are to obtain pieces of high mechanical strength.
