  • Publication number: 20150151146
    Abstract: A system includes a carrier system adapted to be worn by a user and to support at least one of a plurality of differently sized tanks of breathing gas, a bracket connector attached to the carrier system, and a plurality of brackets. The carrier system may, for example, be part of a breathing apparatus such as a self-contained breathing apparatus. Each of the plurality of brackets has a different configuration. Each of the plurality of brackets is attachable to an associated one of the plurality of differently sized tanks and to the bracket connector. For each one of the plurality of brackets, an assembly that includes the one of the plurality of brackets and the associated one of the plurality of differently sized tanks, when attached to the bracket connector, positions the associated one of the plurality of differently sized tanks in a predetermined manner relative to the carrier system.

  • Publication number: 20140102898
    Abstract: A system includes a polymeric housing and a first connector in electrically conductive connection with a first component within the housing. The first connector includes a first extending member formed from a conductive loaded polymeric material. The first extending member is formed such that an interior thereof includes conductive elements within a matrix of the polymeric material so that the interior is electrically conductive and an exterior surface thereof comprises the polymeric material and is less conductive than the conductive interior. The conductive interior of the first extending member is in electrically conductive connection with the first component. The first connector further includes a first extending conductive element in electrical connection with the conductive interior of the first extending member. The first extending conductive element extends from the first extending member to pass through the polymeric housing.

  • Patent number: 8522418
    Abstract: A protective helmet includes an outer shell having a generally dome-shaped section and a brim extending outwardly from the dome-shaped section. The dome-shaped section and the brim are formed from a thermoplastic material. The helmet further includes a brim support in operative connection with at least a portion of the brim. The brim support is formed from a material that is more heat resistant than the thermoplastic material. The brim support is sufficiently rigid to limit deformation of the brim upon exposure to high temperature. The brim support material can, for example, have a melting point above 500° F. A method of limiting high-temperature deformation in a helmet includes molding an outer shell of the helmet to consist essentially of thermoplastic material, the outer shell comprising a generally dome-shaped portion and a brim extending outwardly from the dome-shaped section by at least 2.
