ARTICLE WITH RETROREFLECTIVE FEATURE AND RADIO FREQUENCY-RESPONSIVE FEATURE

摘要

PROBLEM TO BE SOLVED: To achieve a system that provides visual and electronic information in a readily identifiable combination tag where a radio frequency-responsive element is in close proximity to a retroreflective element.;SOLUTION: The combination tag 10 includes a retroreflective article 12 with an optical article 13 and a reflective layer 15. The optical article has an optical surface 16 and a structured surface. For example the optical article can include as optical elements glass microspheres (optical beads) or cube corner reflectors. The reflective layer is deposited on at least a portion of the structured surface of the optical article. For example, the reflective layer can include a non-contiguous metal layer. The combination tag also includes an antenna 24 and an integrated circuit 22. The radio frequency-responsive element 14 has information storage and transmission capabilities adapted to enable an interrogation system to obtain information from the radio frequency-responsive element. The radio frequency-responsive element is coupled to one of the optical surface or the rear surface of the optical article.;COPYRIGHT: (C)2010,JPO&INPIT
