Abstract:
L'invention concerne un circuit comprenant dans un même boîtier : un circuit intégré (2) incluant au moins une interface de communication en champ proche (22) de type NFC, et une interface de communication d'un autre type (24, 26) ; et un circuit intégré comprenant un module de sécurité (3) incluant une mémoire non volatile (35), la mémoire non volatile étant exploitée par l'interface NFC pour stocker des données de configuration.
Abstract:
The invention relates to a method for transmitting an at least synchronization and data signal (S) on a unifilar bus between a master device and at least one slave device, wherein a first transmission channel (C1) from the master device to the slave device modulates the periodic pulse width between a first level (V0) and second level (V1) of a same sign voltage relative to a reference potential, and a second transmission channel (C2) amplitude modulates at least one of the voltage levels between said level and at least one third level (V0’) different from the two others and from the reference potential.
Abstract:
The invention relates to a method for detecting a variation in distance relative to an axis of at least one point of an object rotating around said axis by a terminal (1) in a position that is stationary relative to the axis (41) and capable of emitting a radiofrequency field to at least one resonant circuit (2) attached to the object. Said method includes the steps including measuring and recording, on the terminal side, a maximum value of a quantity representative of the coupling of an oscillating circuit of the terminal and said at least one resonant circuit; and detecting a variation in said periodic maximum.
