Abstract: Embodiments of the present invention include a camera having two modes: a visible light imaging mode (day-mode) and an IR imaging mode (night-mode). In the visible light imaging mode, an IR filter is in line with the lens assembly. In the IR imaging mode, the IR filter is mechanically removed, and IR light is allowed to pass to the sensor. In one embodiment, in the IR imaging mode, IR lighting is provided by an IR LEDs on the camera to illuminate the scene. In one embodiment, the various components are chosen, balanced and optimized so that images captured using visible light and images captured using non-visible light are both in focus. In one embodiment, an algorithm determines when there sufficient visible light is present and when it is not, and thus determines when to switch the camera from one mode to another.

Abstract: Reinforced polymeric foam compositions having a polymeric foam core and a structurally reinforcing facer that are recyclable and can contain venting means between the foam and facer. The structurally reinforcing facer contains a thermoplastic polymer film layer and a gas-breathable layer between the foam core and the thermoplastic polymer film layer. The reinforcing facer is free of a polyethylene terephthalate layer, a metal foil layer, a paper layer, or any combination thereof.
