Title
(EN) REPLACEABLE PRINT APPARATUS COMPONENT
(FR) COMPOSANT D'APPAREIL D'IMPRESSION REMPLAÇABLE
Abstract
(EN)
A replaceable print apparatus component includes a print material reservoir, a print material within the reservoir and a sensing system including an integrated circuit configured to connect to and communicate over a digital bus. The sensing system includes at least one sensor, a digital controller, an analog to digital converter electrically coupled to the digital controller, and a memory array electrically coupled to the digital controller. The digital controller is configured to generate a clock signal for timing operations of the integrated circuit. The operations include initiating the at least one sensor based on values stored in the memory array and generating outputs of the at least one sensor via the analog to digital converter.

La présente invention concerne un composant d'appareil d'impression remplaçable qui comprend un réservoir de matériau d'impression, un matériau d'impression à l'intérieur du réservoir et un système de détection comprenant un circuit intégré conçu pour se connecter à un bus numérique et communiquer sur ce dernier. Le système de détection comprend au moins un capteur, un dispositif de commande numérique, un convertisseur analogique-numérique couplé électriquement au dispositif de commande numérique, et un réseau de mémoire couplé électriquement au dispositif de commande numérique. Le dispositif de commande numérique est conçu pour générer un signal d'horloge pour des opérations de synchronisation du circuit intégré. Les opérations comprennent l'initialisation du ou des capteurs sur la base de valeurs mémorisées dans le réseau de mémoire et la génération de sorties du ou des capteurs par l'intermédiaire du convertisseur analogique-numérique.
