Abstract: Light re-reflection in a picture generation unit for a heads up display is reduced by a housing having walls that are “surfaced” to have inclined surfaces, which reflect light incident upon them toward inclined surfaces on a second and opposing surfaced wall. Re-reflections of light off the surfaced sidewalls attenuates light to a degree that it cannot generate a visible image.

A cracking furnace uses the heat transfer tube. The heat transfer tube and cracking furnace have good heat transfer effects and small pressure loss.

Abstract: Anomalous images generated by a picture generation unit of a heads up display are suppressed by a light-suppressing horn placed inside the picture generated unit. The horn is sized, shaped and arranged to receive scattered light that is reflected from mirrors of a digital micromirror device, which are in their “off” position but which nevertheless reflect light toward surfaces of the picture generation unit and which are subsequently emitted from the picture generation unit lens.
