Abstract: A method for fabricating a plural-layer, body-contacting protective and cushioning interface structure including the steps of (a) providing at least a pair of viscoelastic, non-springy, acceleration-rate-sensitive core layers, (b) facially bonding these two core layers using curable and initially wet, flowable adhesive which is based upon a solvent of one character, and thereafter (c) completing the fabrication by the application of a curable, and initially wet, flowable barrier-layer material to form a fully moisture-impervious but gas-permeable coating barrier layer which substantially completely encloses the bonded core layers.

Abstract: An LED light source has a housing having a base. A core projects from the base; is substantially cylindrical and is surrounded by tubes. The core and the base are arrayed about a longitudinal axis. A circuit board in the base supports LEDs. Each of the LEDs is positioned with one of the tubes in a one-to-one relationship at one end of the core. A heat sink is positioned in a heat-transferring relationship with the circuit board and a first reflector is attached to another end of the core. To direct the light emitted by the LEDs from the source to the reflector, the interior of the tubes can be plated with a highly reflective material. In one embodiment, each of the tubes is fitted with a light guide, each light guide extending from a position immediately above one of the LEDs to a position adjacent the reflector.
