Abstract: A respiratory mask system includes a mask interface and a headgear assembly. The headgear assembly is adjustable and comprised of an elastic portion, a non-elastic portion and a restriction mechanism configured to provide a force resisting movement of the non-elastic portion when the elastic portion is extended. There is a support beam coupled to the non-elastic portion and extending along a portion of the headgear that is curved along its longitudinal extent. In this way particular seal modules can be comfortably fitted to a user and any blow off force is mitigated. A particular example of the respiratory mask system includes provision for removable attachment between the seal and a mask frame, the mask frame and a yoke of the headgear; and between a conduit and the mask frame.

Abstract: Furniture systems are provided with integrated media presentation devices, such as a display panel, where internal connections between the media presentation devices and internal components for signal and power delivery are provided via low-voltage cables, and where the integrated media devices are connectable to an external computing or media content delivery device. In some embodiments, a mobile media access and control unit is provided that may be removably interfaced with a media presentation device in a low-voltage furniture system for displaying media content and optionally for sourcing power, where the mobile media access and control unit includes a plurality of media inputs for receiving media content from a plurality of computing devices, and a mechanism for selectively delivering media content from one of the computing devices to the media presentation device within the furniture system in response to input from a user.
