摘要： An apparatus for concentrating light from a light source includes a plurality of lenses that are substantially aligned with one another. Each lens includes a light-receiving end configured to receive the light from the light source and a light-transmitting end configured to transmit the light from the lens to a target. The light-receiving ends are aspherical.

摘要： An apparatus for concentrating light from a light source includes a plurality of fibers that are substantially parallel with one another. Each fiber includes a light-receiving end and a light-transmitting end. The light-receiving end is configured to receive the light from the light source. The light-transmitting end is configured to transmit the light from the fiber. The light-receiving ends the fibers extend different distances from a plane that is perpendicular with respect the fibers.

摘要： A stowage bin assembly and method of operation includes a front panel configured to be selectively switched between a transparent mode and an opaque mode, a baggage retaining chamber defined, at least in part, by the front panel. The front panel is moveable between an open position and a closed position. The front panel can be further configured to be selectively switched to a translucent mode.
