Abstract: An optical connector includes a first attachment area for receiving and permanently attaching to an optical waveguide. A light coupling unit is disposed and configured to move translationally and not rotationally within the housing of the connector. The light coupling unit includes a second attachment area for receiving and permanently attaching to an optical waveguide received and permanently attached at the first attachment area. The light coupling unit also includes light redirecting surface.

Abstract: Provided are adhesive articles that include a barrier layer that is substantially impermeable to oxygen gas at ambient temperature and pressure along with a heat-bondable layer, which could be a discrete layer adjacent to the barrier layer or integral with the barrier layer. The adhesive article further includes a backing extending across and coupled to the barrier layer and an adhesive layer extending across and coupled to the backing opposite the barrier layer. The barrier layer reduces or eliminates migration of plasticizers from the bonded seal into the adhesive article, limiting deterioration of tape performance over time.

Abstract: A strap retainer (4) for attaching a chinstrap (3) to a safety helmet (1). The strap retainer (4) includes a clip (5) that has a first latch (52A) that is movable between an engaged position and a retracted position. The first latch (52A) is resiliently biased toward the engaged position. The strap retainer (4) further has a slider (6) that is displaceable between a lock setting and a release setting. The lock setting causes a movement of the first latch (52A) toward the retracted position to be impeded, and the release setting causes the impeding to be suspended.
