Abstract: An interfacing structure is connected, directly or indirectly, to a lens of eyewear, such as a goggle. The interfacing structure is constructed and arranged to be in opposing relation with a user's face in use. The interfacing structure includes a compliance portion comprising a support flange around a periphery of an eye region of the user's face, and a cushion support flange extending from the support flange, the support flange being flexible and resilient. The interfacing structure further includes a cushion configured to engage the user's face in use, the cushion provided to the cushion support flange.

Abstract: An interfacing structure for a head-mounted display unit is constructed and arranged to be in opposing relation with a user's face. The interfacing structure comprises a chassis, the chassis having a wall, and at least one vent extending through the wall. The vent has a first opening on an inner face of the wall and a second opening on an outer face of the wall. The vent is substantially linear between the first and second openings, and/or is configured to allow the passage of light from the second opening to the first opening. The chassis also has at least one light shield portion configured to block light from the vent from entering the user's eye.

Abstract: A patient interface for delivering breathable gas to a patient includes a nasal prong assembly including a pair of nasal prongs structured to sealingly communicate with nasal passages of a patient's nose in use and headgear to maintain the nasal prong assembly in a desired position on the patient's face. The headgear includes side straps and rigidizers provided to respective side straps. Each rigidizer includes a first end portion that provides a connector structured to engage a respective end of the nasal prong assembly and an inwardly curved protrusion in the form of a cheek support that curves inwardly of the connector. The cheek support is adapted to follow the contour of the patient's cheek and guide a respective end portion of the side strap into engagement with the patient's cheek to provide a stable cheek support.

Abstract: A nasal patient interface for delivery of a supply of pressurised air or breathable gas to an entrance of a patient's airways includes a cushion member that includes a retaining structure and a seal-forming structure permanently connected to the retaining structure, a frame member attachable to the retaining structure, and a positioning and stabilising structure releasably attachable to the frame member.

Abstract: A mask system includes a cushion for a mask that seals at its upper extent in a region of the nose that is generally above the tip of the nose or pronasale, and extends across a portion of the cartilaginous framework, alar or flares of the patient's nose, e.g., not extending over or across the nasal bone of the patient's nose.

Abstract: A head-mounted display system comprising: a head-mounted display unit comprising: a display unit housing comprising a display; and an interfacing structure; and a positioning and stabilising structure comprising: a pair of arms connected in use to respective lateral sides of the display unit housing, the arms being substantially rigid and being constructed and arranged to project posteriorly from the display unit housing on respective lateral sides, a posterior portion of each arm comprising a superior arm connection portion and an inferior arm connection portion; a top strap portion to connect between each of the superior arm connection portions of the pair of arms and the head-mounted display unit; and an occipital strap portion to connect between the inferior arm connection portions and engage a portion of the user's head overlying or lying inferior to an occipital region of the user's head in use.

Abstract: A patient interface comprises a support structure and a seal-forming structure. The support structure is arranged to support the sealing portion and is configured to connect to the frame. The sealing portion comprises textile and is attached to the support structure along an outer perimeter of the sealing portion such that in use the sealing portion may be in tension due to reactive stress of the support structure and/or a resilient stretch characteristic of the textile such that the sealing portion exerts a force against the patient's face.

Abstract: A patient interface comprises a seal-forming structure including a textile membrane and a support structure to support the textile membrane. The seal-forming structure may have a varying construction in order to accommodate different regions and the varying contours of the patient's face to ensure a robust and comfortable seal. An air impermeable layer of the textile membrane may have a thickness that varies in different portions of the textile membrane and/or different regions of the cushion assembly. Further, the seal-forming structure may include an underlying cushion, and an arrangement of the textile membrane and the underlying cushion and/or the configuration of the underlying cushion may vary in different regions of the cushion assembly to optimize patient comfort and the effectiveness of the seal in different regions of the patient's face.

Abstract: A patient interface comprises a plenum chamber and a seal-forming structure. The seal-forming structure comprises a support structure arranged to support a sealing portion that is adapted to sealing engage the patient's face in use. The seal-forming structure may also include a seal biasing portion configured to inflate under pressurization within the cavity in the cushion assembly in use to extend the reach of the sealing portion and decouple the sealing portion from external forces.
