Abstract

Dette system omfatter objekter (2) med kodeelementer (3, 4, 5) som særlig er flere elektrisk ledende elementer anordnet etter hverandre og med liten tykkelse. Elementene kan detekteres elektromagnetisk og har en forhåndsbestemt overflatedimensjon og er anordnet i eller på et elektrisk isolerende underlag. Kode- elementene (3, 4, 5) er særlig skilt fra hverandre med samme forhåndsbestemte avstand. Systemet omfatter en elektromagnetisk detektor (8) med minst én senderspole (10) og minst én mottakerspole (13). Senderspolen eller - spolene brukes til å sende ut minst to signaler som er representative for objektets (2) koding og dets omgivelser. Systemet omfatter også midler for å kunne behandle de mottatte signaler i detektoren for å rekonstruere kodings signatur og lokalisere og identifisere det kodede objekt (2).
