  • Publication number: 20220374501
    Abstract: A module for processing a set of n input data comprising a reference datum, which is configured to a) calculate the sum of weights that are associated only with those input data other than the reference datum which have values strictly lower than the value of the reference datum; b) compare the sum calculated in step a) with a first threshold; c) calculate the sum of the weights that are associated only with those input data other than the reference datum which have values strictly higher than the value of the reference datum; d) compare the sum calculated in step c) with a second threshold; e) generate an output datum indicating whether the reference datum is a fractile of the set included in a predetermined subset of fractiles, only if: the sum calculated in step a) is lower than the first threshold and the sum calculated in step c) is lower than the second threshold.

  • Patent number: 9661140
    Abstract: A method for shifting an original call established between a first user device (1) and at least a correspondent device (2) through a first application server (3) in order to route it through a second application server (4), the method comprising—instructing the first application server (1) to forward the original call through the second application server (4) to the first user device (1) upon receiving the application server shift instruction, the first application server being instructed to establish a three-way conference communication between the first user device (1), the correspondent device (2) and the second application server (4) in order to forward the original call from the first application server (3) to the second application server (4); —determining that an incoming call routed from the second application server (4) to the first user device (1) has an identification information matches identification information of the original call; —causing the first user device (1) to pick-up the incoming call

  • Publication number: 20120054271
    Abstract: A method for the synthesis of a user's interactions associated with a user, characterized in that it comprises the following steps: aggregating a user's interactions from interaction means (10, 20, 30, 41, 40) associated with a user; identifying the users concerned by said actions; identifying the interaction means associated with each concerned user; recovering the information received to establish at least one interaction via the identified interaction means; checking the availability of the identified interaction means; caching inside the user's terminal retrieved information related to said identified users' available interaction means; presenting interaction notifications to the user.

  • Publication number: 20100131597
    Abstract: A device (D) is dedicated to the control of communications of communication terminals (T1, T2) capable of establishing at least telephone or multimedia communications. This device (D) comprises control means (MC) responsible, when a telephone or multimedia communication is established between a first communication terminal (T1) of a first user and a second communication terminal (T2) of a second user, and when an action on the first terminal (T1) causes the second terminal (T2) to be placed on hold, for proposing the establishment of an instantaneous messaging communication via the Internet or an Intranet between communication terminals of the first and second users, so that they can exchange text messages.

  • Patent number: 6613723
    Abstract: The present invention provides a process for preparing an overbased barium complex and an overbased barium complex prepared thereby. The process includes the steps of: heating a mixture of barium hydroxide monohydrate and an isomeric mixture of from about C10 to about C15 alcohols in the presence of a solvent, thereby producing a first mixture; contacting the first mixture and an isomeric mixture of from about C8 to about C10 branched carboxylic acids, thereby producing a second mixture which includes unreacted barium hydroxide; and contacting the second mixture and carbon dioxide, thereby producing the overbased barium complex. The overbased barium complex of the present invention is useful in the stabilization of halogen-containing polymers.

  • Patent number: 6267680
    Abstract: The connection between the core 12 of the flexible joint and the external part concerned is provided by two strips mounted head to foot in a through rectangular opening in the core, on the ends of which the strips abut by their widened head 18. The body 17 of the strips, engaged completely in the rectangular opening, is slightly wider than the terminal part 19 of the strips, narrower to facilitate their assembly. The fixing holes, one in the head 18, the other (22) in the terminal part 19, lie one over the other but are of slightly different diameters.
