Title: Systeme de securite pour la transmission de donnees de point a point
Inventor: KAUFFMAN MARC W
IPC: H04N7/16
Filed: 1996-04-01
Abstract: Communication sécurisée point à point d'informations vers des terminaux spécifiques assurée via un réseau partagé. Longtemps avant l'établissement d'une session d'information avec un terminal particulier d'une pluralité de terminaux, un identifiant de session unique est délivré de façon sécurisée au terminal par une entité hautement sécurisée. Les informations à fournir au terminal sont ensuite chiffrées sous l'identifiant de session de ce terminal par un gestionnaire de connexion non sécurisée. Les informations chiffrées sont insérées dans des emplacements désignés dans un multiplex de signal. Le multiplex de signal est transmis sur une portion du réseau desservant le terminal qui doit recevoir les informations. Le terminal est informé des emplacements désignés des informations chiffrées dans le multiplex de signal et d'une fréquence de transmission à laquelle le multiplex de signal est transporté sur la portion de réseau. Le terminal se règle sur la fréquence de transmission pour localiser le multiplex de signal, récupère les informations chiffrées aux emplacements désignés dans le multiplex, puis déchiffre les informations en utilisant l'identifiant de session unique du terminal.

Abstract: A system in which a private base station supports the registering of multiple mobile stations and generates a personalized call delivery feature for each registered mobile station is provided. Each mobile station registers separately with the base station when within communication range of the base station. When registration of a mobile station with a private base station is performed, the private base station generates a local unique address for each one of the multiple mobile stations registering with the private base station. This unique address for a registered particular mobile station is also sent to the private base station location register. When the private base station receives an incoming call for a particular one of the mobile stations, this local unique address associated with the particular portable station is provided by the base station location register as part of the incoming call information also received by the base station thereby allowing the base station to distinctively alert the particular mobile station. By obtaining a local unique address for each of the mobile stations, the private base station is also able to advantageously offer various intelligent features which are personalized according to customer needs. For example, a calling party may have his or her name displayed on the reached mobile station for the convenience of the user at this mobile station.

Title: Masking cylinder bore extremities from internal thermal spraying
Inventor: DONOVAN DAVID A
IPC: C23C4/16
Filed: 1996-09-27
Abstract: Method of masking one or more extremities of a cylinder bore from internal thermal spraying, when using a rotary gun inserted from one end of the bore, by essentially the steps of: (a) supporting one or more inflatable mask members adjacent an end of the bore wall; (b) pressurizing the inflatable mask member to expand and annularly engage an end of the bore, the mask being constituted of an inflatable and collapsible air tight bag of heat resistant (fiberglass) cloth coated on opposite sides with a sacrificial heat resistant non-stick coating (silicone). The inflatable characteristic of the mask member allows it to conform to the periphery of the cylinder bore extremities, and allows it to be easily installed in or through the component in its deflated condition. The mask is reusable by being comprised of coating material that may gradually be sacrificed to heat and wear of the over spray.
