Abstract: A patient interface including a positioning and stabilizing structure that is configured to maintain a first seal-forming structure and a second seal-forming structure in a therapeutically effective position. The positioning and stabilizing structure comprises a frame coupled to the plenum chamber. The frame includes a central portion coupled to the plenum chamber outside of the cavity. The frame also includes a pair of arms that extend away from the central portion in a posterior direction past the second seal-forming structure. The pair of arms are more flexible than the central portion. The positioning and stabilizing structure also includes headgear straps coupled to the frame, which configured to provide a tensile force to the first seal-forming structure and to the second seal-forming structure into the patient's face via the frame.

Abstract: The present invention relates to a method of dynamic channel switching in a wireless mesh network that is in conformance with an IEEE 802.11s standard. The method comprises the steps of transmitting a request frame to a node for scanning a channel associated with the node; determining a link quality of the channel; receiving a response frame from the node; and switching to the channel if the switching metric is larger than a switching threshold, wherein if otherwise, remain unswitched. The switching metric integrates the interference, transmission frame size, latency of channel switching and data rate of the node on the channel.

Abstract: There is provided an in-ear earphone having a housing for receiving an electroacoustic transducer and an expansion adaptor unit which is coupled to the housing of the in-ear earphone.
