Abstract

L'invention concerne un clavier informatique multifonctions pouvant être utilisé avec un dispositif de communications sans fil. Le clavier comprend une unité d'interface, un bus sériel universel (USB), une unité de chargement, une unité de commande, une unité de traitement de données, une unité de traitement des signaux audio, et un émetteur-récepteur. L'unité d'interface est placée sur une partie du corps principal du clavier, ce qui permet l'installation du dispositif de communications sans fil. L'unité de chargement charge le dispositif de communications directement connecté à l'unité d'interface, au moyen d'une tension électrique provenant d'un hôte par l'intermédiaire d'un concentrateur USB. L'unité de commande délivre en sortie des signaux de commande sur la base d'une entrée de clé. L'unité de traitement des données transmet une entrée de signaux de données à travers l'entrée de clé vers le dispositif de communications sans fil, par l'intermédiaire de l'interface ou vers l'hôte, par l'intermédiaire du concentrateur USB sur la base d'un premier signal de commande. L'émetteur-récepteur reçoit un signal RF ou effectue une communication de données avec un noeud externe au moyen d'une communication infrarouge ou d'une communication sans fil en champ proche.
