Abstract: A bicycle helmet system comprising a helmet and a chin bar is disclosed. The chin bar is removably coupled to the helmet and wrapped circumferentially around a portion of the helmet. The chin bar may include a rear buckle configured to tighten the chin bar around the helmet. The chin bar may also include two side buckles that engage with side recesses on the helmet when the chin bar is removably coupled to the helmet. The chin bar may also include two alignment protrusions positioned to engage with alignment recesses on the helmet when the chin bar is removably coupled to the helmet.

Abstract: A bowl may be configured to include an outer body that has a u-shaped cross section, and the outer body may have a bottom configured to support the bowl on a surface, the bottom also including a circular groove around a circumference of the bottom and a bracket within the circular groove, wherein a foot is inserted within the groove, and wherein the foot is secured to the circular groove by the bracket. The bowl may include an inner body, wherein the inner body is concave and dome-shaped. The inner body may hold a liquid or solid, and the inner body is connected to an upper edge of the outer body. An internal cavity is formed by the outer body and inner body, and the internal cavity is insulative. The connection formed by the upper edge of the outer body and the inner body may be seamless.

Abstract: A variable efficiency filter media. The variable efficiency filter media is a composite media formed of at least two different types of filter media, such as standard efficiency media and high efficiency media. The variable efficiency filter media has at least two different efficiency levels. The different efficiency levels can be spread across different zones. The filter media types for both the standard and high efficiency media can be spun media, melt blown media, nanofiber media, micro-glass media, cellulose media, carded staple fiber media, and the like. The variable efficiency filter media may be produced by any of an air laid or wet laid process.

Abstract: A container having a base and a lid is provided. The lid may be rotatable about a hinge from a closed configuration to an open configuration and may be secured, via one or more latching assemblies. The latching assembly may comprise a latch body, a locking member, a biasing member, and an activating member. Additional features of the container may include handles and strength increasing features. The base and lid may also feature attachment points for various accessories. A carry strap may attach to the base of the container to allow a user to lift and carry the container. The container may also have a wheels attached to the bottom portion and/or across the bottom portion to one side of the sidewall structure. In addition, in exemplary containers with wheels, a pull handle may be attached to a side opposite the wheels. The lid may include a lid support member that can act as a molle board to releasably secure items to the lid support member while also providing structural support to the lid.

Abstract: Disclosed is a composite filter media. The composite filter media is formed from multiple layers of media material including a nanofiber media layer, where the layers are laminated, bound, or otherwise composited to each other. The composite filter media can comprise at least one nanofiber layer comprising polymeric media material having a geometric mean fiber diameter of about 100 nm to 1 ?m, and fibers configured in a gradient such that ratio of the geometric mean diameter of fibers at the upstream face of the nano fiber layer to the geometric mean diameter of fibers at the downstream face of the nano fiber layer is about 1.1 to 2.8, preferably about 1.2 to 2.4.
