Abstract: Roadway and vehicular-mounted safety reflectors include a reflective field that incorporates a plurality of discrete crystals that internally reflect light and return the light in a desired directional pattern determined by the internal reflection characteristics and orientation of the crystals. The directional pattern is chosen to optimize the visibility and functionality of the reflector.

Abstract: A highway marker and vehicle mounted detection system in which the highway marker includes LEDs of different colors that can be selected under different conditions, and non-visible light LEDs for transmitting information to passing vehicles and between highway markers.
Abstract: Communication methods and apparatus using ultraviolet (UV) light are provided. Save UV communication devices, including remote control units, can use highly efficient UV LEDs and very low-noise UV photodetectors. In some cases, the LEDs emit light at wavelengths below 400 nm, below 320 nm, or even below 280 nm. In one embodiment, communication can be achieved using an LED that emits less than about 1 picowatt of UV energy at a photodetector distance of up to at least about 10 meters. Longer range communication can also be achieved at higher power levels. Photodetectors having very low dark currents at room temperature, such as below about 1×10?9 A/m2, are preferable.
