    Abstract: PROBLEM TO BE SOLVED: To provide a method and a system for controlling access between a main processor and a peripheral device which are connected through a communication bus with excellent security. SOLUTION: At least one token selectively permitting access to one or a plurality of peripheral devices is assigned to all or a part of programs executes by the main processor. The token is provided by an auxiliary processor which uses a memory different from the main processor at least at an early stage. Existence of a permission token for access to the related peripheral device is checked for each request for one access of the program to one of the peripheral devices. COPYRIGHT: (C)2005,JPO&NCIPI

    Abstract: PROBLEM TO BE SOLVED: To provide a normalized noise flow having a fixed output rate. SOLUTION: A method and a circuit for normalizing a noise source providing an initial bit flow conditions the state of an output bit to the respective states of the bits of the initial flow examined by words of identical lengths and further conditions the state of a current output bit to the state of at least one previous output bit upon occurrence of a word of bits of identical states.

    Abstract: PROBLEM TO BE SOLVED: To determinate such a fact that a memory cell is written to either state, even when a memory cell is written to either state after its manufacture.
    SOLUTION: A memory cell 1 comprises at least two detectable states including one unprogrammed state, and at least a first branch in series between two read voltage applying terminals 4, 5. The cell further comprises front-end reading stages 6, 7 provided with two changeable resistors in parallel which has different resistances with a first predetermined difference, poly silicon writing resistors Rp1, Rp2, and a writing stage which can be accessed by a writing circuit where the terminals of the writing resistors can cause the irreversible reduction of the values.

    Abstract: Commutateur optique intégré réalisé dans et sur un substrat semi-conducteur, comportant un corps photoconducteur (PC) comprenant une première extrémité (1) configurée pour recevoir un signal électrique d'entrée et une deuxième extrémité (2) configurée pour délivrer un signal électrique de sortie, le corps photoconducteur (PC) ayant un état électriquement passant activé par la présence d'un signal optique (SO) et un état électriquement bloqué activé par l'absence du signal optique (SO), dans lequel la direction allant de la première extrémité vers la deuxième extrémité définit une direction longitudinale (D3), et le corps photoconducteur a une section transversale orthogonale à la direction longitudinale (D3) diminuant progressivement selon la direction longitudinale (D3) depuis la première extrémité (1) vers la deuxième extrémité (2).
