Title
(DE) Methode zur Eichung einer Sonde
(EN) Method for calibrating a probe
(FR) Procédé de l'étalonnage d'une sonde
Abstract
(EN)
A probe (20) for insertion into the body of a subject, the probe (20) having distal (22) and proximal ends, and including an electronic microcircuit (90), which stores information relating to calibration of the probe (20). Preferably, the microcircuit (90) stores a calibration code, which is encrypted. Alternatively or additionally, the microcircuit (90) stores a usage code, which controls availability of the probe (20) to a user thereof. Preferably, the probe (20) includes access control circuitry (90) that allows the usage code to be changed so as to reduce the availability of the probe (20), but not to increase the availability thereof.

(FR)
Cette invention concerne une sonde (20) destinée à être insérée dans le corps d'un patient, laquelle sonde (20) comprend une extrémité distale (22) ainsi qu'une extrémité proximale, et renferme un microcircuit électronique (90) contenant des informations relatives à l'étalonnage de ladite sonde (20). Le microcircuit (90) contient, de préférence, un code d'étalonnage crypté. Dans ce même mode de réalisation, ou dans un autre mode de réalisation, le microcircuit (90) contient un code d'utilisation qui permet à l'utilisateur de gérer la disponibilité de la sonde (20). La sonde (20) comprend, de préférence, des circuits de commande d'accès (90) qui vont permettre de modifier le code d'utilisation afin de réduire, et non d'accroître, la disponibilité de ladite sonde (20).
