Abstract: La présente invention se rapporte à un procédé unique d'identification de la présence, et de préférence de l'identité d'un fluorophore par stimulation optique d'un ou de plusieurs de ces fluorophores au moyen d'un signal optique qui a été modulé en intensité dans le domaine temporel. Le fluorophore stimulé produit une fluorescence qui est démodulée pour générer un signal électrique correspondant à la modulation de l'intensité de la fluorescence. Enfin le signal électrique est comparé à la modulation du signal optique ce qui permet de déterminer si il y a présence ou non du fluorophore. Ce procédé peut être utilisé seul ou associé à des procédés connus d'analyse optique de la fluorescence des fluorophores afin de déterminer la présence de ces derniers.

Granted: 2010-05-04
Abstract: A power line communications system has a power line (120) having a plurality of phase lines (Red, Yellow, Blue) upon which noise level varies with time. The system determines quiet periods when noise upon the phase lines is at a reduced level and transmits one or more data packets within the quiet periods, preferentially transmitting to the subscriber stations (S1, S2 ...) during quiet periods occurring on the phase line to which they are coupled. This increases data throughput in the system.
