Abstract: Protective clothing and/or equipment may comprise a modular helmet assembly which comprises a plurality of impact mitigation modules positioned between an outer layer and an interior layer of the helmet, optionally with a plurality of perforations or openings in an outer shell of the helmet. The plurality of impact mitigation assemblies may comprise an impact absorbing array of impact mitigation structures having at least one filament and a lateral support wall or connecting element. When force is applied to the exterior surface, the structures of the impact absorbing materials deform in a desired and controlled manner, reducing the force received by the interior layer.

Abstract: A helmet includes a helmet shell having an outer surface, an inner surface, and a plurality of slit openings. Each slit opening extends along a portion of the helmet shell. The slit openings include a pair of top slit openings that each extend longitudinally along a top portion of the helmet shell, where each top slit opening has a first length. The pair of top slit opening are spaced apart and define a flexible helmet portion spaced between the pair of top slit openings. The flexible helmet portion extends along the first length from a first end of the flexible helmet portion to a second end of the flexible helmet portion opposite to the first end, and the flexible helmet portion has a stiffness that varies along the first length from the first end to the second end.

Abstract: Pigmented masonry compositions are provided that include chemically treated carbon black pigments having attached an organic group including an ionic or an ionizable group, the ionic or ionizable group being present at a level from 1.0 to 3.0 ?mol/m2. The compositions exhibit excellent color consistency and jetness and provide consistent color after long term exposure to high levels of moisture.

Abstract: The full-face helmet system comprises a full-facemask that combines the strength of a facemask frame and a reinforcement layer to allow for improved visibility, safety and impact performance, while reducing weight. The full-facemask comprises a reinforcement layer and a facemask frame, the reinforcement layer may be coupled to the external surface or internal surface of a facemask frame. The reinforcement layer may match or substantially match one or more contours of the facemask frame, the reinforcement layer comprises at least one vent opening that is coincident with the player's mouth.

Abstract: Fiber optic modules having pigtails and related strain relief constructions for the fiber optic harness are disclosed. The fiber optic module assembly has a fiber pigtail exiting module, the assembly includes a main body of the module defining an internal chamber disposed between a first side and a second side, a plurality of fiber optic components disposed at the first side of the module, and a fiber optic harness including the fiber pigtail. The fiber optic harness includes a plurality of optical fibers within a portion of a protective tube on the pigtail portion and a strain-relief assembly for inhibiting movement between the optical fibers and protective tube. Consequently, the strain-relief assembly secures the plurality of optical fibers and the protective tube to the main body of the module.

Abstract: A mounting assembly for mounting fiber optic equipment to a cable tray is disclosed. The mounting assembly includes a support frame adapted to attach to fiber optic equipment. A mounting device attaches to the support frame. The mounting device is adapted to removably attach the support frame and, thereby, the fiber optic equipment to the cable tray.
