Title: Dynamically controlled routing using dynamic management of intra-link traffic to virtual destination nodes
Inventor: CARON FRANCE
IPC: H04Q3/545
Filed: 1995-10-26
Granted: 2001-08-28
Abstract: A dynamically controlled routing (DCR) telecommunications network (31A) comprises a plurality of network switching elements (a, b, c, o, t) interconnected by circuit groups (a-b, o-a, o-b, o-c, ...) for carrying call s, and a network processor (25A) communicating with the network elements. At least one of the nodes is a virtual destination node (V) which is a logical entity corresponding to a group of two or more components which are network elements. A link to the virtual destination node need not correspond to a circuit group but is a set of circuit groups connecting to the components of  the virtual destination node. Final destinations outside the DCR network can  be associated with the virtual destination node as an intermediate destinati on node, thereby allowing a call to exit the DCR network via any of the components of the virtual destination node rather than via only one Unique Exit Gateway. Where a link to the virtual destination node comprises a plurality of circuit groups, the store of the associated switching element m ay include proportions for those circuit groups. When attempting to route a cal l via the link to the virtual destination node, the switching element may attempt the circuit groups in dependence upon the proportions.

Abstract: This invention relates a secret data storage device capable of setting password data which is easy for a specific user to memorize but is difficult for others to understand. A registration password data item composed of an arbitrary hieroglyphic data item or a combination of an arbitrary hieroglyphic data item and the color specifying data corresponding to the hieroglyphic is entered by selectively operating the hieroglyphic key 12b and color key 12d in the key input section 12. Similarly, using the color specifying data item and the like, a collation password data item is inputted. Then, it is determined whether or not the registration password data item coincides with the collation password data item entered this time. When it has been determined that they coincide with each other, the secret data stored in the secret data memory 17d is accessed and the accessed data appears on the display section 19.

Abstract: Système de commande de processus comprenant au moins une variable manipulée et au moins une variable commandée, ce système constituant une méthode de commande fiable d'un processus. On obtient des contraintes prédéterminées des variables manipulées et des variables commandées, ainsi que les valeurs actuelles des variables manipulées. Le dispositif de commande est chargé avec des paramètres qui définissent un dispositif de commande optimal, ces paramètres étant calculés en dehors du processus. Pour déterminer lesdits paramètres, une instruction unique min-max est définie pour un modèle du type cas le plus défavorable du processus qui opère en conjonction avec un dispositif de commande du type cas le plus favorable. L'instruction unique min-max est convertie en une expression canonique correspondante sous forme d'un problème de minimalisation dont la solution résultante est le paramètre. De nouvelles valeurs sont calculées pour les variables commandées pour un nombre prédéterminé de points à venir, de telle sorte que les valeurs des variables commandées se situent dans la plage prédéterminée, ceci conférant une fiabilité optimale au dispositif de commande résultant. Les variables manipulées sont également calculées de manière à se situer en-deçà des contraintes prédéterminées et les variables commandées sont calculées de manière à se situer dans une plage prédéterminée lorsqu'elles peuvent être commandées. Entre plusieurs solutions, c'est la plus fiable qui est sélectionnée. Les variables manipulées sont ensuite ajustées de telle sorte que le système de commande de processus fasse évoluer les valeurs des variables commandées pour qu'elles atteignent les valeurs calculées.

Abstract: A scaffolding structure is configured to provide dual walk-through areas with each walk-through area being at different elevations of a scaffolding section. Each section of the scaffolding structure includes two end frames with each end frame having a forward post, a center post, and a rearward post. The forward and center posts are connected by a walk board support and the center and rearward posts are connected by a work board support. The end frames are interconnected by a walk board joined at one end with the walk board support of one end frame and joined at the other end with the walk board support of the other end frame. A work board also interconnects the end frames in similar fashion with one end of the work board joined with the work board support of one end frame and the other end of the work board joined with the work board support of the other end frame. Cross-bracing of the end frames relative to each other and a handrail connected between the rearward posts of the end frames are employed as needed. Receptors in the ends of the forward, center, and rearward posts are configured to closely receive a stud to enable multi-level, vertical stacking of like scaffolding sections. Electrical outlets are provided at the center post of the end frames. An electrical conduit positioned within the center post provides electrical continuity between an electrical power source and the outlets. Jumpers are employed to establish continuity between adjacent vertical scaffolding sections. A substantially non-load bearing ladder may be attached to one or more of the end frames. A corner walk board and a corner work board are provided to achieve continuous scaffolding around corners of structures.

Abstract: System and method for providing a customer with the ability to obtain temporary advanced telecommunication services in the Advanced Intelligent Network (AIN) for the customer's calling line by dialing a call to special access code, without the intervention of a service representative. The call is recognized as a request for an initiation of a temporary advanced telecommunication service with respect to the customer's calling line. On the basis of the recognition, an association may be retained between the calling line number and the service switching point serving the calling line number. This retained association may be used later in the activation of the temporary advanced telecommunication service for the calling line number. The call is routed to a rental service interface through which rental information from the caller may be collected. This rental information may be compiled into a rental agreement that is used as the basis for activation of the temporary advanced telecommunication services with respect to the caller's calling line number. Confirmation of the activation may be provided to the communication. The rental information may also include a termination time for the temporary advanced telecommunication services. The termination time and the retained association may be utilized to initiate the deactivation of the temporary advanced telecommunications services.

Abstract: A hybrid electric vehicle includes a traction motor driven by a traction battery, and a supplemental or secondary electrical source for charging the traction battery. In order to warm the passenger compartment during cold weather, heat is applied from the traction motor and the secondary source. Under some conditions, there may be insufficient heat to adequately warm the passenger compartment. The traction motor efficiency is lowered, so that more heat is generated, to aid in supplying the deficiency. In an embodiment in which the traction motor is an ac motor, the efficiency is lowered by applying a direct current to the motor. In an embodiment in which the ac motor is an induction motor, the efficiency is lowered by increasing the average slip frequency.
