Abstract: A head protection system comprises a helmet shell, a visor mounting for pivotally mounting a visor to the shell to enable the visor to be moved between raised and lowered positions, and a retainer for releasably retaining the visor to the helmet. The system includes a visor adapted for mounting on the shell which comprises a substrate of transparent thermoplastic material and a backing substrate comprising a plurality of layers of high performance, ballistic resistant material. The system may further include a second visor which can be releasably connected to the shell using the same visor mounting and which may have a different construction and primary function.

Abstract: Disclosed is an apparatus and method for managing and storing excess amounts of fiber-optic cable in a telecom rack. According to one embodiment, the apparatus comprises a fiber-optic cable slack take-up device attached to an arm. The arm is mounted to a supporting member attached to a side of the telecom rack and movable from a first stored position to a second deployed position. Access to the fiber-slack take-up device is provided by situating the arm in the second position. Situating the arm in the stored position places the slack take-up assembly, along with the excess fiber-optic cable, out of the way of operators working in the equipment aisle. Further embodiments provide means for safe-guarding the minimum bend radius of fiber-optic cable being used. The apparatus and method are useful for overcoming the space requirements of in-rack fiber storage systems known in the art.
