Abstract
(DE) Die Erfindung bezieht sich auf eine Markierungseinrichtung (1, 11) für die Kennzeichnung von Objekten, mit einer Kodierung aus Bereichen (4, 5, 13) mit unterschiedlichen magnetischen Eigenschaften. Die Markierungseinrichtung ist dadurch gekennzeichnet, dass magnetische Bereiche (4, 5, 13) derart magnetisch vorgespannt sind, dass deren Hystereseschleifen (7, 8, 15) auf der Feldstärkeachse (H) gegenüber dem zur Magnetisierungsachse (M) symmetrischen Verlauf verschoben sind. Die Erfindung bezieht sich ferner auf ein Verfahren und eine Vorrichtung zur Herstellung sowie Verfahren zum Auslesen einer solchen Markierungseinrichtung.
(EN) The invention relates to a marking device (1, 11) for the identification of objects, comprising a coding consisting of areas (4, 5, 13) of differing magnetic properties. The marking device is characterized in that the magnetic areas (4, 5, 13) are magnetically biased in such a way that their hysteresis loops (7, 8, 15) are displaced on the field strength axis (H) in relation to the progression which is symmetrical to the magnetisation axis (M). The invention also relates to a method and apparatus for producing a marking device of this type and to a method for reading the same.
(FR) L'invention concerne un équipement de marquage (1, 11) pour marquer des objets, présentant un codage sur la base de zones (4, 5, 13) dont les caractéristiques magnétiques diffèrent. L'équipement de marquage est caractérisé en ce que les zones (4, 5, 13) magnétiques sont magnétiquement polarisées de manière telle que leurs cycles d'hystérésis (7, 8, 15) sur l'axe d'intensité du champ (H) sont décalés par rapport au tracé symétrique de l'axe de magnétisation (M). Ladite invention concerne également un procédé et un dispositif pour fabriquer un tel équipement de marquage, ainsi qu'un procédé pour en faire la lecture.
