Abstract: PROBLEM TO BE SOLVED: To make it possible to easily record and retrieve a story on an optional printed matter such as a newspaper, a magazine, a periodical publication, a catalogue, a book, and a pamphlet. SOLUTION: Since a user identifier(UID) is normally set and controlled by a service provider and added to each document (original) when distributing the UID by a normal publisher, the UID can be read out by a user, preferably by a simple reader for electronically inputting it to a user's personal archive. Although the personal archive can be maintained by a human or another (or the same) service provider, the archive can be individually set in order to determine the contents of a user's own archive. A controlled access system having access certification (time controllable) issued to a requested user assures a user access to a stored electronic copy.

Abstract: The present invention relates to switching in electronic networks. Many data transmission protocols and technologies used in such networks, such as TCP/IP and Ethernet, use variable-length packets for transmission. Often however, the nodes that make up these networks typically contain high-speed cell switches that only support fixed-size data units. To support variable-length packets in such a fixed-size cell switch non-interleaving switching and transmission must be offered. The present invention provides such a solution in essence by segmenting a variable-length frame into a plurality of fixed-length cells including a start-of-frame cell, one or more continuation cell(s), and an end-of-frame cell and routes said fixed-length cells through said switch, thereby providing, at an output of said switch, subsequent and deadlock-free transmission of consecutive cells of a certain frame, and block any cell of a different frame from interleaving. This leads to better average delay characteristics and removes the need for packet reassembly.
