Abstract: SELF-CLEANING LABEL FOR AUTOMATIC OBJECT IDENTIFICATION SYSTEM A self-cleaning label is provided for use in an automatic object identification system. The label comprises a backing member having a plurality of fins attached to it. A strip of reflective material is affixed to the front surface of each fin for "reading" by the components of the system. The fins are aerodynamically designed so that the flow of air past the label carrying surface serves to clean the surface and protect the settling of dirt thereon.
