  • Patent number: 6578171
    Abstract: A method of transmitting binary data by a sender to a receiver over a transmission channel includes a formatting function integrated with a function of external coding of the binary data. The method applies in particular to the case where the sender uses a turbocoder with an interleaver of the “x to xe” type, and where the receiver uses a turbodecoder with an interleaver of the “x to xe” type.

  • Patent number: 6400726
    Abstract: The invention proposes a method for allocating, to a plurality of elements, authorisations for access to a shared resource, including the step (E4) of storing the address of elements capable of accessing the shared resource, characterised in that it includes the steps of determining (E6), for the plurality of elements, a number (TTJ) of authorisations for access to the resource, the said authorisations together forming a cycle, then successively assigning (E8, E80) each of the said authorisations to the elements, during the said cycle, an access authorisation being assigned to an element according to at least the number of times the element under consideration accessed the resource during the preceding cycle, and finally storing (E88, E890) the number of times each element accesses the resource during the said cycle.

  • Publication number: 20020055353
    Abstract: The invention concerns a method and device for declaring at least one functionality of a node in a network comprising at least two nodes, each node connected to the network sending over the network, following the occurrence of a predetermined event on the network, a set E of data representing its functionalities and if, amongst the sets E of data sent over the network, none includes at least one data item representing a predetermined functionality, the method generates the predetermined event on the network and sends the set E of data comprising at least one data item representing the predetermined functionality on the network

  • Patent number: 6229799
    Abstract: The device according to the invention shares a transmission medium between communication devices by allocation of authorizations to send on the medium, to each communication device. It has: a memory (65) for storing a table (64) representing communication devices (7) sharing the medium, each assigned a priority level (435, 438, 441, 444) for access to the medium; a device (94, 460, 462, 529, 543, 544, 545, 559A) for updating the access priority levels according to an estimated requirement for transmission on the medium by the communication devices under consideration.

  • Patent number: 6122267
    Abstract: The methods for transmission of sequences or frames of data provide for retransmitting, with a central device (21), frames of data which reach it, to destination devices, by transmission of downlink frames when the destination device is a peripheral device (24), each downlink frame having systematically a service message activating a protocol controlling access to the transmission medium shared by the central device (21) and the peripheral devices (24), and possibly a frame of data. The central device (21) and at least one peripheral device (24) form a system which is particularly well suited to a local area network, notably with a wireless transmission medium.

  • Patent number: 5991275
    Abstract: A digital communication converter includes: a connection unit with a communication unit from which it receives or to which it delivers data frames; and a unit for sending/receiving over a transmission medium in order to transmit, by means of the medium, data frames which are delivered to it and/or to deliver information frames which it receives by means of the medium. A transmission control unit delivers, respectively to the connection unit and the sending/receiving unit, frames which have been delivered to it respectively by the sending/receiving unit and by means of the connection unit. A memory stores an address relating to the communication unit, this address being used for operating a protocol for controlling access to the transmission medium.
