Abstract: In some examples, OTDR event detection and light power level measurement-based fiber optic link certification may include performing, at one end of a device under test (DUT) of a network, a light power level measurement. An OTDR measurement may be performed at the one end of the DUT to detect at least one event associated with the DUT. Based on analysis of the light power level measurement and the OTDR measurement, an event classification may be generated to classify the at least one event associated with the DUT.

Abstract: The invention relates to a lithium vanadium oxide which corresponds to the formula Li1+?V3O8 (0.1???0.25). It is composed of agglomerates of small needles having a length l from 400 to 1000 nm, a width w such that 10<l/w<100 and a thickness t such that 10<l/t<100. It is obtained by a process consisting in preparing a precursor gel by bringing ?-V2O5 and a Li precursor into contact in amounts such that the ratio of the concentrations [V2O5]/[Li] is between 1.15 and 1.5 and in subjecting the gel to a heat treatment comprising a first stage at 80° C.-150° C. for 3 h to 15 days and a second stage between 250° C. and 350° C. for 4 min to 1 hour, under a nitrogen or argon atmosphere. It is useful as an active material of a positive electrode.

Abstract: The invention relates to the preparation of an optionally carbonaceous ?-LiV2O5 material. The process consists in preparing a composition formed of carbon and of precursors of Li and of V and in subjecting it to a heat treatment. The composition is prepared by bringing carbon, ?-V2O5 and a Li precursor into contact in amounts such that the ratio of the [V2O5]/[Li] concentrations is between 0.95 and 1.05 and the carbon is in excess of at least 25% with respect to the stoichiometry. The heat treatment is carried out in two stages: a first stage at a temperature between 90° C. and 150° C. for a time of 1 to 12 hours and a second stage at a temperature between 420° C. and 500° C. for a time of between 10 min and 1 hour, under a nitrogen or argon atmosphere or under vacuum.

Abstract: This is a method and a system for animating on a screen (3, 3?, 3?) of a mobile apparatus (4, 4?, 4?) an avatar (2, 2?, 2?) furnished with a mouth (5, 5?) using an input sound signal (6) corresponding to the voice (7) of a speaker (8) having a telephone communication. The input sound signal is transformed in real time into an audio and video stream in which the movements of the mouth of the avatar are synchronized with the phonemes detected in said input sound signal, and the avatar is animated in a manner consistent with said signal by changes of posture and movements by analysing said signal, so that the avatar seems to talk in real time or substantially in real time instead of the speaker.

Abstract: The invention relates to a method and a system enabling a user to animate an interactive 3D figure known as an agent (2) during an application program, said agent being cut out of the background of the graphic interface of the program from which it is independent. A first file comprising data defining the agent and the animation algorithms thereof is created in a manner known per se. Said data comprises color, texture and meshing parameters relating to the agent. The first file is interpreted by calculating the behavioral parameters of the agent (2) in real time by means of a 3D motor 3D (23, 24) based on recognition of key words pronounced and/or written by the user in order to automatically animate the agent according to predetermined criteria corresponding to said key words or a combination of said key words.
