Abstract

Un dispositif de suivi d'emplacement gardé par un parent est utilisé avec un dispositif de rapport d'emplacement porté par l'enfant, dans lesquels à la fois le dispositif de suivi et le dispositif de rapport d'emplacement ont tous les deux un émetteur-récepteur de signal radio de plage courte et un récepteur d'emplacement GPS - et le dispositif de rapport a également un émetteur de données cellulaire et un dispositif de commande. Le dispositif de positionnement a un émetteur-récepteur de données cellulaires et un écran d'affichage. Si le dispositif de positionnement et le rapporteur deviennent séparés selon plus d'une distance prescrite, le récepteur GPS de dispositif de rapport envoie des données depuis le récepteur par l'intermédiaire de l'émetteur cellulaire vers un récepteur accessible par Internet, ce qui fournit un affichage visuel sur l'écran de dispositif d'emplacement de parent indiquant les positions relatives de parent et enfant.
