Abstract: Ridge vents configured to cover an open ridge of a roof and allow a flow of air to exit from the open ridge through the ridge vents are provided. The ridge vents include a center portion having a length and a plurality of grooves. Left and right portions are connected to the center portion. The center portion is configured to flex along it's length, thereby forming a ridge vent angle between the left and right portions. The formed ridge vent angle is configured to correspond with a slope between roof decks defining the open ridge.

Abstract: A patient interface device is provided that includes a patient sealing assembly, such as a mask having a rigid shell and a cushion coupled to the rigid shell, and a forehead support movably coupled to the patient sealing assembly. The forehead support is moved by an wedge-type adjustment mechanism such that linear translation of the wedge moves the forehead support among the plurality of positions and fixes the forehead support in a desired position among the plurality of positions.

Abstract: An earphone assembly for an in-ear listening device and method for filtering a portion of an audible sound output are disclosed. An earphone comprises a housing configured to receive a nozzle, a plurality of drivers each having an acoustical output disposed within the housing, and an elongated passageway disposed within the housing configured to filter at least an audible portion of a sound wave output from at least one of the plurality of drivers. The method comprises providing an elongated passageway to provide an increased path length and connecting an output of the at least one driver to the elongated passageway to configure the sound output to be received within the elongated passageway to acoustically filter a portion of the sound output from the at least one driver.

Abstract: An earphone assembly for an in-ear listening device is disclosed. The earphone assembly has an inner housing comprising a nozzle, configured to receive a sleeve for placement into a user's ear, and a balanced armature motor assembly. The balanced armature motor assembly is mounted in the inner housing so as to form an acoustical seal between the inner housing and the balanced armature motor assembly. The earphone assembly also includes an outer housing configured to receive the inner housing. The inner housing can comprise a recess for receiving a paddle of the balanced armature motor assembly. Alternatively, the outer housing can be formed with a nozzle for receiving a sleeve for placement into a user's ear canal, and the inner housing can comprise a spout, which is received in a recess in the outer housing.
