  • Methods of forming retroflective structures having a helical geometry
    Patent number: 8157391
    Abstract: Retroreflective structures and methods of forming the same comprise a body of material extending along a helical path about a longitudinal axis and a plurality of retroreflective optical elements positioned along the helical path of the body of material, and constructed and arranged to retroreflect electromagnetic energy directed from a range of angular orientations about the longitudinal axis.
    Type: Grant

  • Method of making and using retroreflective fibers
    Publication number: 20090025872
    Abstract: A method of making and using retroreflective fibers and especially to the making of retroreflective fibers from finely cut strips from a thin sheet of material having a corner cube array formed on one side thereof. Other layers of materials including a second thin sheet of material having a corner cube array may be attached to the first thin sheet of retroreflective material. The thin strips may be further chopped into shorter strips and added to coating compounds, such as paint.

  • Multiple layer reflective tag
    Publication number: 20090027775
    Abstract: A reflective tag apparatus has a top layer having micro apertures therein and having a surface message therein and a second layer having a sub surface message thereon mounted over a reflective layer. The reflective layer may be retroreflective using an array of corner cubes and may be a structure that is diffractive or resonates iridescent colors and may contain coatings, dyes and pigments to provide light control.
