Abstract: Systems and methods for designing and optimizing tools are provided. A computational fluid dynamics (CFD) simulation model implemented by a processor is provided to simulate a fluid flow inside the tool to generate a particle density distribution of fluids inside the tool. The particle density distribution is converted to a spatial distribution of fluid concentration of the mixture which allows for high resolution visualization of fluid flow in the tool.

Abstract: A respiratory mask body defining a breathable air zone for a wearer and having a shut-off valve is provided. In an exemplary embodiment, the mask body includes one or more inlet ports configured to receive one or more breathing air source components. The shut-off valve is operable between a closed position and an open position, and when in a closed position the shut-off valve prevents fluid communication between the one or more inlet ports and the breathable air zone and the shut-off valve returns to an open position in the absence of an applied force.

Abstract: A water treatment device for filling at least one bottle with treated tap water includes a housing unit having a reservoir, and at least one valve arranged in fluid communication with the reservoir, the valve having a water inlet/air exit port arranged adjacent to the housing unit, and a water exit/air inlet port arranged opposite the water inlet/air exit port, whereby when the valve is actuated to its open condition, water flows through the valve and into the bottle, and air entrapped in the bottle flows through the valve and into the surrounding environment. When the valve is in its closed condition, air and water do not flow through the valve.

Abstract: A hand-held polishing apparatus is provided for polishing an optical fiber connector. The optical fiber connector mounted on the end of an optical fiber includes a connector housing and a ferrule. The polishing apparatus includes a connector mount to receive and hold the optical connector to position the end face of the ferrule adjacent to a polishing media. The polishing apparatus includes a housing having an upper portion and a base portion, a drive assembly and a lubricant dispensing system. The drive assembly controls orbital movement of the optical connector and linear movement of the polishing media through the polishing device, and the lubricant dispensing system supplies a lubricant from an internal reservoir disposed with in the housing to the polishing media near the end face of the ferrule of the optical connector.

Abstract: A water bottle for use in connection with a water treatment device includes an opening with a diameter of at least about 0.87 inches, a diameter of no greater than about 1.06 inches, and a height of at least about 6.56 inches, and a height of no greater than about 8.02.

When the valve is in its closed condition, air and water do not flow through the valve.

Abstract: A water treatment cartridge, or insert, for use in connection with a water treatment device such as a gravity-fed water pitcher or the like includes a support structure and water treatment material arranged in combination with the support structure.

Abstract: Systems and methods for applying or dispensing fluids such as surgical prep solution. The applicator includes a distributor element and a container of surgical prep solution. The distributor element includes a projecting element that separates at least two orifices in the distributor element to provide uniform distribution of the surgical prep solution.

Abstract: A brush segment, a brush element, a brush assembly, and methods of making and using the same are disclosed. The brush segment includes a center portion with inner and outer edges. The center portion also includes first and second side edges. A plurality of bristles extends outwardly from the outer edge. The inner edge includes an interlock arrangement. The side edges have an attachment arrangement for attaching adjacent segments. The brush element includes a center portion and inner and outer edges. A plurality of bristles extends outwardly from the outer edge. The inner edge includes an interlock arrangement for restraining rotation of adjacent elements assembled into a brush assembly. Two or more brush elements are secured together to form a rotary brush assembly.

Abstract: The present invention describes systems and methods for applying or dispensing surgical prep solution. The applicator system includes a spreader element and a container of surgical prep solution. The spreader element includes a body with an orifice covered by a pad. The orifice is in fluid communication with a passage through an elongated stem connected to the body. The container may be collapsible with only limited recovery. The spreader element may include a receptacle for receiving the container.
