A disappearing interface system for a device, such as an appliance (e.g., a cooking range) having an interactive user interface, a light-emitting device (e.g., a LED), a microprocessor based LED fader electronic control system that uses a PWM signal to drive an A/D circuit to control the intensity (e.g., fade in/out) of the light-emitting device.
L'invention concerne un système d'interface escamotable destiné à un dispositif, tel qu'un appareil (par exemple, un fourneau de cuisine) comprenant une interface utilisateur interactive, un dispositif électroluminescent (par exemple, une DEL), un système de commande électronique à équilibreur de DEL fondé sur un microprocesseur et mettant en oeuvre un signal PWM, aux fins d'entraînement d'un circuit A/N, de manière à commander l'intensité (par exemple, un fondu-enchaîné) du dispositif électroluminescent.
