Abstract

Un système de visualisation comprend un élément de commande de visualisation pouvant être excité, une source d'énergie produisant du courant et une partie de commande. La partie de comande, à son tour, comporte un élément d'adressage en forme d'echelle, un fil d'entrée, un fil d'activation et un fil d'adressage d'entrée. L'élément d'adressage en forme d'échelle possède une paire de barres latérales et une multiplicité d'échelons, y compris un échelon d'entrée, et au moins un échelon d'adressage, ainsi qu'un échelon d'activation, les barres latérales ayant une réluctance magnétique inférieure aux échelons. Le fil d'entrée est couplé magnétiquement à l'échelon d'entrée pour produire un signal de flux d'entrée dans l'élément d'adressage, ledit signal de flux d'entrée ayant une direction représentative de l'état d'excitation de l'élément de commande de la visualisation. Le fil d'activation est magnétiquement couplé à l'échelon d'activation, à la source d'énergie et à l'élément de commande de de visualisation pour commander le transfert d'énergie de la source d'énergie à l'élément de commande de visualisation de manière à réguler l'excitation dudit élément de commande. Enfin, le fil d'adresssage d'entrée est magnétiquement couplé à l'échelon d'adressage pour commander de manière sélective le couplage du signal de flux d'entrée au niveau de l'échelon d'entrée avec l'échelon d'activation afin de réguler le couplage par le fil d'activation.
