Abstract: Air cleaner assemblies, related methods, components therefor, and features thereof are described. In depicted examples, the air cleaner assemblies and components optionally use advantageous housing seal features. In some examples, a filter cartridge for an air cleaner includes a media pack extending along a longitudinal axis between opposite inlet and outlet flow ends and defining an outer perimeter with opposite straight sides and a first curved end. The filter cartridge can include a seal arrangement circumscribing the media pack outer perimeter, wherein a portion of the seal arrangement extends beyond a first plane defined by the media pack outlet flow end and a portion of the seal arrangement is disposed between the first plane and a second plane defined by the media pack inlet flow end, wherein the seal arrangement is aligned along a third plane disposed at an oblique angle to the first and second planes.

Abstract: Garments and apparel that animate subsurface muscles, joints and tendons. The garments can include athletic wear such as leggings that conform to both the thigh and calf of a user and arm coverings that conform over the arm, and even over the torso of the body. Other applications can include dancewear, theatrical costuming, medical and therapeutic products. The garment can include seams about slits, each slit being parallel to one another running down the exterior sides of the leggings and arm coverings. Sewn to the edges of the slits, beneath the slits can be a sublayer elastic material having a different color and/or texture than the surface color and/or texture of the garment. Alternatively, instead of seams, the material can be formed from a chemically or another technically produced fabric that has designated stretch and non-stretch areas engineered at selected locations.
