IPC: H04H20/69
Filed: 2002-05-01
Abstract: A system and method for the simultaneous transmission of point-to-point and broadcast signals over an optical network are provided. In accordance with this invention, the user terminals of the system are divided into groups of user terminals, each assigned a different waveband. Each user terminal within one group is assigned a different point-to-point code within its corresponding waveband for encoding and decoding point-to-point signals exchanged with the central office. A signal broadcast code is assigned per groups of users and therefore per wavebands, for all of the users of a same group to use. All signals on all wavebands are transmitted through the network, but each user terminal may only access point-to-point signals addressed to himself and a copy of the broadcast signal.

Abstract: L'invention concerne un électrolyte qui permet d'éviter la perte d'efficacité dans une pile et la perte de capacité liée à la répétition du cycle de charge/décharge d'une pile. L'invention concerne aussi un procédé relatif à l'élaboration de l'électrolyte, et par ailleurs une pile redox utilisant cet électrolyte. L'électrolyte a une teneur en NH4 inférieure ou égale à 20 ppm, et une quantité, formulée en tant que concentration de Si (ppm) x volume d'électrolyte (m<3>), inférieure à 5 ppm m<3>/m<2>. La limitation du taux d'impuretés permet d'éviter la perte d'efficacité dans le fonctionnement d'une pile, en liaison avec l'opération de charge d'une électrode de carbone dans cette pile, car une telle opération apporte des impuretés propres au cycle de charge/décharge.
