Publication number: 20200059448Abstract: In a method for processing messages exchanged on a social network, a data processing apparatus gathers from the social network a reference set of messages pertaining to a user-selected reference context. The data processing apparatus then applies a multidimensional aggregation to the reference set of messages, whereby the messages of the reference set are grouped in an multidimensional array of groups having at least two dimensions. In each dimension, the array comprises a number of groups that correspond to a number of values of a certain message feature. Each group in a dimension corresponding to a certain message feature aggregates all the messages of the reference set whose message feature has a same value. Then, a user interface is displayed, which shows the reference set of messages as aggregated in at least two dimensions of the array.Type: ApplicationFiled: August 13, 2019Publication date: February 20, 2020Applicants: TELECOM ITALIA S.p.A., POLITECNICO DI TORINOInventors: Vincenzo Cuciti, Marina Geymonat, Chiara Lorenza Remondino, Barbara Stabellini, Paolo Tamborrini

Patent number: 10128973Abstract: A method for activating an ONU in a multi-wavelength PON. Other ONUs may be already active and transmit upstream signals to the OLT on various upstream channels. The new ONU transmits an activation signal superimposed to such upstream signals. Since the ONU may include an uncalibrated tunable transmitter, initially the activation signal wavelength might be different from that upon which the ONU shall be activated. The activation signal optical power is lower than the other upstream signals, so as not to impair their reception at the OLT. The OLT operates the ONUs already active on the upstream channel on which the new ONU shall be activated to suspend transmission for one or more time gaps, during which the OLT detects the activation signal. This improves activation signal detection conditions, thereby allowing to increase its bitrate. An acceptable duration of the activation procedure can then be achieved.Type: GrantFiled: September 2, 2014Date of Patent: November 13, 2018Assignees: TELECOM ITALIA S.p.A., POLITECNICO DI TORINOInventors: Roberto Gaudino, Valter Ferrero, Roberto Mercinelli, Maurizio Valvo
