Abstract: La présente invention concerne un appareil et un procédé permettant le verrouillage et le déverrouillage de combinés téléphoniques mobiles ou d'autres équipements. Au moment de l'achat, tout combiné est à l'état "non mis en service". En dehors des appels d'urgence ou de l'appel de mise en service, aucun appel ne peut être fait tant que le combiné n'a pas été déverrouillé. Le combiné, qui est capable de recevoir un module d'identification d'abonné ou module SIM (Subscriber Identity Module) pourvu d'un code d'identification réseau (ou autre) et d'un mot de code, voit son fonctionnement limité au verrouillage et déverrouillage en fonction de l'identité correspondant au code d'identification du module SIM. En outre, le combiné comporte un processeur ayant reçu par programmation un numéro unique d'identification d'appareil et une clé. Tous les combinés fabriqués en un même lot peuvent être équipés de cette clé, qui est enregistrée par claquage ou tout autre procédé dans une zone de la mémoire du combiné, de façon à ne pas pouvoir être lue sans se détruire. Le processeur de combiné est également programmé pour produire une clé spécifique du combiné, résultant du code d'identification du combiné et de la clé spécifique du lot de fabrication. Lors de la mise en service du combiné, le centre de service client dépendant de l'opérateur du réseau émet un modificateur à destination du combiné. Le combiné utilise le modificateur pour modifier sa clé spécifique de combiné de façon à obtenir une clé spécifique d'opérateur. La clé spécifique d'opérateur, utilisée en association avec le code d'identification réseau (ou autre) du module SIM, permet de produire un mot de contrôle. Si le mot de contrôle correspond au mot de code lu et effacé sur le module SIM, le combiné se déverrouille (se valide) pour une utilisation normale. L'invention concerne également d'autres fonctionnalités telles que le reverrouillage du combiné en employant des principes analogues et la fourniture d'un numéro d'identification personnel permettant de déverrouiller de façon permanente l'appareil pour qu'il puisse être utilisé avec n'importe quel module SIM compatible.

Title: Naphthalimide colorants with improved compatibility in refrigeration and air conditioning lubricants
Inventor: MAHAFFEY ROBERT L JR
IPC: C07D221/14
Filed: 1999-02-12
Abstract: Novel naphthalimide-derivative colorants are provided which are present in a neat liquid state at ambient temperature and pressure. Such colorants are produced through the reaction between 4-chloro (or bromo)-1,8 naphthalic anhydride and at least one etheramine, at least one branched alkylamine, or mixtures thereof. The inventive colorants are excellent leak detection agents for refrigeration and air conditioning systems. These naphthalimide derivatives are completely miscible in all different types of standard refrigeration and air conditioning lubricants. Furthermore, since these colorants are liquid, they are not susceptible to crystallizing within such systems. Thus, the inventive naphthalimide leak detecting agents cannot cause the failure of such machinery due to the crystallization of colorant and subsequent clogging of system compressors. Methods of making and using such inventive naphthalimide-derivative colorants are also disclosed.
