Abstract: A hose having an asymmetrical cross-section but which exhibits symmetrical bending and crush resistance regardless of the direction of the bending and/or crushing forces exerted on the tube. The tube includes an outer wall and an inner strengthening rib which is coextruded with the outer wall, the inner rib fabricated from a material having a durometer which is at least equal to, or higher, i.e., equal or higher resistance to deflection and/or indentation, than the material out of which the outer wall is fabricated.

The tube includes an outer wall and an inner strengthening rib which is coextruded with the outer wall, the inner rib fabricated from a material having a durometer which is at least equal to, or higher, i.e., equal or higher resistance to deflection and/or indentation, than the material out of which the outer wall is fabricated. In one embodiment the rib defines a third lumen.

Abstract: Nasal interface systems and related components. An embodiment of the system employs a nasal interface comprised of a base portion and a soft pad portion. The base portion employs one or more side-entry fluid supply hoses and flow redirection structure which gently and quietly redirects the flow of incoming fluid to avoid the creation of noise. One or more fluid supply hoses are connected to the one or more inlets, preferably by releasable engagement structure. The nasal interfaces of the invention are sleek, unobtrusive, visibly attractive and avoid exposure of expelled gases toward partners of the wearer.

Abstract: The present disclosure generally relates to systems and devices for spraying fluid materials such as paints, stains, and the like, and more specifically, but not by limitation, to a fluid level indicator for an airless fluid sprayer. In one example, an airless fluid sprayer is provided and includes a fluid container, a controller, and a fluid level indication module implemented by the controller to generate an indication of a level of fluid material in the fluid container.

Abstract: In one example, a handheld fluid sprayer is provided and includes a housing, an assembly having at least one of a motor and a fluid pump, and at least one assembly support feature. The assembly is mounted to the housing with the at least one assembly support feature. The at least one assembly support feature includes a first portion having first and second opposed surfaces and a second portion having first and second opposed surfaces. The second portion extends from the first portion such that at least one of the first and second surfaces of the second portion is at least substantially orthogonal to the second surface of the first portion.
