  • Patent number: 11304241
    Abstract: A method for transmitting data packets through a random-access (RA) transmission channel shared by a plurality of user terminals uses and exploits a function F for assigning and distributing transmission resources F(u) to the user terminals, knowledge of the graph of which is shared by the sending user terminals and the receiving station in a preliminary step. During the decoding of the received packets, the graph {(u, F(u)} of the assigning and distributing function is exploited by the receiving station to minimize, or even to decrease to zero, the number of replica-location correlations required in case of failure of the conventional CRD-SA protocol decoding process.

  • Patent number: 11261310
    Abstract: The present invention relates to a method for treating fragments of polyvinyl butyral (PVB) in which glass shards are encrusted in or on the surface of the PVB. The method involves placing PVB fragments in contact with an aqueous solution comprising a cationic surfactant and a weak base, to obtain a mixture. This mixture, subjected to ultrasound within a defined temperature range, leads to separation of the glass shards and the PVB. In particular, the inventors have discovered that the combined, simultaneous, and complementary action of a weak base, a cationic surfactant, and ultrasound, at an appropriate temperature, made it possible to detach and/or unembed the glass shards fixed to the collected PVB without degrading the polymer matrix.
