Patent

CA 2192329

Information can be obtained from a document having printed electronic circuits (82-96) by using an electronic verification machine (108, 224) that determines the electrical characteristics or signatures of the circuits printed on the document. The electronic verification machine ( 108,224) electronically couples with the circuit applies an excitation signal such as an AC signal (242) having a predetermined frequency to the circuit. A detection circuit (226A-226H) in the electronic verification machine then generates a detection signal in response to the excitation signal which represents the characteristics of the circuit printed on the document. The electrnic verification machine (108, 224) can also be used to stigmatize the document by applying a signal to the electronic circuits having sufficient strength to alter the electronic circuit.

On peut extraire des informations d'un document présentant des circuits électroniques imprimés (82-96) à l'aide d'une machine de vérification électronique (108, 224) déterminant les caractéristiques électriques ou signatures des circuits imprimés sur le document. La machine de vérification électronique (108, 224) se couple électroniquement au circuit et applique un signal d'excitation tel qu'un signal de courant alternatif (242) d'une fréquence prédéterminée au circuit. Un circuit de détection (226A-226H) se trouvant dans la machine de vérification électronique génère ensuite un signal de détection en réponse au signal d'excitation, lequel représente les caractéristiques du circuit imprimé sur le document. On peut également utiliser ladite machine de vérification électronique (108, 224) pour marquer le document par application d'un signal aux circuits électroniques présentant une puissance suffisante pour modifier le circuit électronique.
