20080320315 | Method for Creating a Secure Counter on an On-Board Computer System Comprising a Chip Card - According to the inventive method, the chip card, a counting function (FC), a counter (Cpt) and a private key (Cf) stored in the write-only part of the memory region are stored in a persistent memory, the counter and the private key (Cf) being accessible only by the counting function (FC). When the chip card receives a counter request emitted by an requesting entity (ER), the counting function (FC) performs a modification of the counter (Cpt) and a calculation of a signature, and sends a response to the applicant entity (ER). When the on-board system receives the response to the counter request, the signature contained in the response is checked. | 12-25-2008 |
20110162083 | SYSTEM AND METHOD FOR SECURING DATA - The invention relates to a system and method for making data secure. The inventive system is characterized in that it comprises:—a monotonic counter;—a computational entity;—a physical data medium comprising one or a plurality of data blocks, a first master block comprising the last value recovered from the monotonic counter, an identifier of the last data block written on said medium, a first authentication code guaranteeing the authenticity of the written data block or blocks, a second authentication code calculated from the last written data block, said data being fixed at a neutral value, and a third authentication code guaranteeing the authenticity of the first master block, and a second master block forming a replica of the first master block; and—an authentication key. The invention is used, in particular, to make data secure against playback and sudden interruptions in service in embedded systems. | 06-30-2011 |

20160109027 | VALVE SEAT AND VALVE DISC WITH CASCADED GEOMETRIES - Disclosed are a valve seat apparatus and valve disc apparatus. The valve seat can include a substantially hollow seat interior. The substantially hollow seat interior can also define a substantially frusto-conical seat cavity with a radial axis. The substantially hollow seat interior can have first and second wall sections, with the second wall section being aligned at a smaller angle relative to the radial axis than the first wall section. The valve disc can include a substantially frusto-conical valve body with a radial axis. The valve body can include first and second disc surfaces each aligned at an angle relative to the radial axis. The second disc surface can have an angle relative to the radial axis that is smaller than that of the first disc surface. | 04-21-2016 |

20130183382 | Method for preparing pharmaceutical compositions intended for oral administration comprising one or more active ingredients and the compositions comprising same - The present invention relates to fexofenadine granules, to a composition containing them and to a process for the hot-melt coating of fexofenadine. The process for the hot-melt coating of fexofenadine allows efficient masking of its bitter taste without, however, unacceptably slowing down its dissolution. | 07-18-2013 |
20130251794 | Method for preparing pharmaceutical compositions intended for oral administration comprising one or more active ingredients and the compositions comprising same - The present invention relates to a method for “hot melt coating” of pharmaceutical active ingredients characterized by organoleptic or physicochemical properties that it is desirable to mask. | 09-26-2013 |

20150299861 | Device for Synthesising Core-Shell Nanoparticles by Laser Pyrolysis and Associated Method - A device for synthesising core-shell nanoparticles by laser pyrolysis is provided. The device includes a reactor having a first chamber for synthesising the core, which is provided with an inlet for a core precursor; a second chamber for synthesising the shell, which is provided with an inlet for a shell precursor; and at least one communication channel between the two chambers for transmitting the core of the nanoparticles to be formed in the first chamber towards the second chamber. The device also includes an optical device for illuminating each of the two chambers, and at least one laser capable of emitting a laser beam intended to interact with the precursors in order to form the core and the shell. | 10-22-2015 |
20150303462 | Method For Producing An Electrode For A Lithium Accumulator And Associated Electrode - A method for producing an electrode comprising a core-shell nanocomposite material of which the core is made from silicon and the shell from carbon is provided. The method includes A) synthesising the nanocomposite material by pyrolysing a silicon core to form a core and then pyrolysing a carbon shell precursor to form a carbon shell around the core, wherein the quantities of silicon and carbon precursor are injected in a proportion such that the mass percentage of carbon in the nanocomposite material is greater than or equal to 45%; B) dispersing the nanocomposite material synthesised in step A) in a solvent to form an ink; C) applying this ink to a support intended to form an electricity collector; D) eliminating the solvent from the ink applied to the support in step C) to obtain the electrode; E) pressing or calendaring the electrode. | 10-22-2015 |
