Abstract: A wireless proximity detection system employs short-range wireless communication to detect the proximity of a user device within a strictly defined wireless zone and as a result trigger a desired action. The proximity detection system may utilize one or more leaky feeders to define the wireless zone and the associated received signal strength(s) detected by the user's wireless device. Alternatively, a compact planar antenna structure coupled with a highly shielded radio transceiver is used to allow a similar precise low-power radio beam to be emitted defining a small location to enable identification of a wireless device such as a smartphone in a given area in front of the device. The planar antenna structure allows a compact and low-cost fabrication method and the use of common printed circuit fabrication methods provide an integrated solution.

Abstract: This invention relates to headgear and a patient interface, or components of a headgear or patient interface, such as a nasal cannula. In one embodiment is a size adjustable headstrap to be provided as a headgear or a part thereof, in another is a portion of a headstrap or component for association therewith in which the portion or component facilitates improved location of the strap upon a user's face, in another embodiment is a system for encapsulating or covering a connector from contact with a user's face or facial skin, in another embodiment is a face mount part or body for a patient interface of a particular configuration, and in yet a further embodiment is a gases flow manifold for delivering of gases to a patient interface of a particular configuration for improved patient comfort.

Abstract: A connector is used to connect a gases supply to a user. The user can be fitted with an interface, such as a cannula, while the gases supply can include a conduit. The connector interfaces between the conduit and the interface. The connector has a female assembly and a male assembly that connect together, such as by push fit. The male assembly includes an inner portion sized and configured to mate with a first female connector and an outer portion sized and configured to alternatively mate with a second female connector.

Abstract: A breathing assistance apparatus is configured with features that improve serviceability of the apparatus. The apparatus can include animations to provide instruction regarding correcting easily-identified fault conditions and to provide instruction regarding routine maintenance routines. The apparatus also can be configured with top level control menus that are obscured in a manner to limit manipulation of the top level control elements by unauthorized users.

Abstract: A respiratory assistance apparatus is configured to provide a heated and humidified glow of gases and has a control system that is configured to detect a fault in the flow path. A flow path is provided for a gases stream through the apparatus from a gas inlet through a blower unit and humidification unit to a gases outlet. A flow rate sensor is provided in the flow path and is configured to sense the flow rate and generate an flow rate signal and/or a motor speed sensor is provided that is configured to sense the motor speed of the blower unit and generate an indicative motor speed signal.
