Patent

CA 2718141

This invention provides a system and apparatus that is able to authenticate and prevent illegal manufacturing and unauthorized operation of disposable bioprocess components. This invention utilizes a ferro-electric random access memory (FRAM) chip to store error-correctable information on a RFID tag attached to the disposable bioprocess components, where the error-correctable information is written into the memory chip, so that the information can remain in the chip when the RFID tag and disposable bioprocess component is gamma-sterilized. Also, this invention includes 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 unjustified 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 dans la puce mémoire de façon à y demeurer 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.
