Patent

CA 2718129

This invention provides a system and apparatus that is able to authenticate and prevent ille-gal manufacturing and unauthorized operation of dis-posable bioprocess components. This invention uti-lizes a ferro-electric random access memory chip (FRAM) chip to store error-correctable information on a RFID tag attached to the disposable bioprocess components, where the error-correctable information is written in sequence into the memory chip, so that the redundant information can remain in the chip when the RFID tag and disposable bioprocess com-ponent is gamma-sterilized. Also, this invention in-cludes a method for authenticating the disposable bioprocess component that reduces liability in that a counterfeit poor quality disposable component is not used on the hardware so the user will not file an un-justified complaint.

Cette invention concerne un système et un appareil pouvant authentifier des composants de bioprocédé jetables et empêcher leur fabrication illégale et leur exploitation non autorisée. Le procédé de l'invention met en uvre une puce à mémoire vive ferroélectrique (FRAM) pour stocker des données de correction d'erreur sur une étiquette RFID fixée aux composants de bioprocédé, lesdites données de correction d'erreur étant inscrites en séquence dans la puce mémoire de sorte que les données redondantes puissent demeurer dans la puce lorsque l'étiquette RFID et le composant de bioprocédé jetable sont stérilisés aux rayons gamma. Linvention concerne également un procédé d'authentification du composant de bioprocédé jetable, qui limite le risque d'utilisation d'un composant de bioprocédé contrefait de qualité médiocre sur le matériel, et empêche ainsi l'introduction d'une plainte injustifiée de la part de l'utilisateur.
