Patent CA-2357160-A1 (CA)
Inventor: LI JIN
IPC: G06F9/44
Filed: 2001-09-10
Abstract: A wizard user interface generates an interim system product during forward traversal of the wizard's pages and causes the generated interim system product to revert (i.e. be restored to a condition associated with a previous wizard page) during backward traversal of the wizard's pages. Advancing to a next page of the wizard causes a system product to be generated. The generated interim product is application dependent and may comprise one or more components, such as a generated electronic file or an amendment to an existing file for example, which are not merely by-products of the wizard mechanism. Backtracking to a previous wizard page causes the generated interim system product to revert. The wizard user interface allows observation of, and interaction with, the generated interim system product by the user prior to wizard completion.

Title: Ip routing optimization in an access network
Inventor: RAJANIEMI JAAKKO
IPC: H04L12/56
Filed: 2000-03-08
Abstract: In an access network which supports a mobile IP  protocol, a very mobile MS  might perform several handovers between access nodes during a long session which may cause inefficient mobile IP routing. In the present invention, an access node, which is the target of a handover during an IP session, is arranged to check the optimal routing in respect of the mobile IP, too. For that purpose, the access node is aware of the most preferred mobility agent, normally the closest one, which should be used. In a handover situation the system, preferably the access node, checks (31, 32) whether there is a more preferred mobile IP mobility agent which should substitute for the current mobility agent of the IP session. If there is a more preferred mobility agent for that access node and the preferred mobility agent is not the same as the current mobility agent, the connection to the current mobility agent is closed (33), and a new connection to the preferred mobility agent of the respective access node is opened (34).

Title: Automatic conversion of telephone number to internet protocol address
Inventor: BRAND JOEL
IPC: H04L29/12
Filed: 2000-02-25
Abstract: A conversion system and method allows a calling party to transmit a message to a telephone belonging to a recipient party wherein the message is transmitted via an Internet Protocol network.      This conversion system and method preferably utilizes an Internet Protocol gateway.      The Internet Protocol gateway preferably includes a controller and a database.      In use, a telephone number of the recipient party is preferably transmitted to the Internet Protocol gateway from the calling party. Then, the controller preferably directs this telephone number to the database. The database preferably matches the telephone number of the recipient party to an Internet Protocol address which corresponds with the telephone number and returns this corresponding Internet Protocol address to the controller. Finally, the Internet Protocol gateway responds to the conversion system and method by returning the Internet Protocol address. This conversion system and method then contacts an appropriate server associated with the Internet Protocol address and transmits the message over the Internet Protocol network. The message is then transmitted from the appropraite server to the telephone number of the recipient party. Once the message is transmitted to the telephone number of the recipient party, a communication link is established between the calling party and the recipient party via the Internet Protocol network. This communication link allows both the calling party and the recipient party to communicate with each other. Further, the Internet Protocol gateway has the messaging capabilities of an Intelligent Network service such as signalling system no. 7 protocol.

Abstract: Flat articles are gathered on stack supports (2) being conveyed past feed points substantially continuously and one after the other. After the gathering operation, bottom edge zones (13) of the gathered articles are exposed for a further processing operation. The corresponding device comprises continuously conveyed stack supports (2) each with an inclined supporting surface (3) and a foot element (4) located in the bottom area of the supporting surface (3). The foot elements are actively connected with the supporting surfaces in such a manner, that they are capable of being pressed against the supporting surface and of being distanced from the supporting surface. In an exposure zone downstream of the gathering zone (1), stack support means (10) being conveyed in synchronism with the stack supports (2) and substantially in the same direction and control means are provided. The stack support means are arranged in such a manner, that at the entrance to the exposure zone (1) they are positioned immediately underneath the stack supports and that further downstream they move away from the stack supports (2) in a downwards direction. The control means act on the foot elements (4) of stack supports (2) conveyed through the exposure zone in such a manner, that these are distanced from the supporting surfaces (3) at the entrance to the exposure zone for letting the stacks slide down onto the stack support means, and that the stacks having slid down onto the stack support means (10) are clamped between the foot element and the supporting surface. The exposed edge zones (13) of the gathered articles can then be processed in a simple way and/or can be taken hold of by further conveying means. The device is simple and is capable of being adjusted to suit various applications.
