  • Roadway and Vehicular-Mounted Reflectors Incorporating a Field of Discrete Crystal Reflectors and Retroreflectors
    Publication number: 20070097295
    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.

  • Biohazard treatment systems
    Publication number: 20050242013
    Abstract: Systems and methods for exposing fluids and other materials that may contain biohazards to ultraviolet radiation are provided. One system for exposing a fluid includes a baffled conduit for conveying the fluid so that the fluid flow and its exposure to ultraviolet radiation is rendered more uniform. Other systems include feedback for determining when to replace light sources and filters and to ensure proper biodosimetry. Additional methods and systems for exposing fluids and other materials that may contain biohazards are also provided.
