Patent number: 8875597Abstract: A steering wheel has a rim with an armature substantially encapsulated by foam. The foam includes a major foam member and a separate minor foam member. The major foam member has a cross-sectional profile effective to cover a major cross-sectional extent of the armature and define a gap in the foam member adjacent the armature. The gap has a maximum cross-sectional width which is equal to or less than the cross-sectional width of the armature, and is substantially filled by said minor foam member.Type: GrantFiled: May 17, 2010Date of Patent: November 4, 2014Assignee: Autoliv Development ABInventors: Laurent Groleau, Olivier Bertrand

Publication number: 20130073023Abstract: A stent insertable in a body vessel, the body vessel defining a vessel wall. The stent includes a plurality of struts, the struts defining a substantially elongated stent passageway, the struts being configured, sized and operatively coupled to each other in a manner such that the stent is deformable between a first configuration and a second configuration. In the first configuration, the stent passageway has a first radial dimension and a first longitudinal dimension, and in the second configuration, the stent has a second radial dimension and a second longitudinal dimension, the second radial dimension being at least as large as the first radial dimension and the second longitudinal dimension being larger than the first longitudinal dimension. The stent is able to expand substantially longitudinally with the body vessel as the body vessel grows without reducing in diameter so as to reduce risks of damaging the vessel wall as the body vessel grows.Type: ApplicationFiled: November 14, 2012Publication date: March 21, 2013Inventors: Rosaire Mongrain, Olivier Bertrand, Richard Lawrence Leask

Patent number: 7789415Abstract: A mounting arrangement for mounting an air-bag module to a hub of a steering wheel. The hub being provided with apertures and cutaway sections and a spring. The spring is moveable from a release position in which parts of the spring do not extend across the apertures or the cutaway sections to a locking position in which parts of the spring extend across the apertures and the cutaway sections. The spring is initially deformed and is held in the release position against blocking elements. The air-bag module is provided with hooks which are positioned on the air-bag module to correspond to the positions of the apertures and the cutaway sections on the hub. The air-bag module is provided with an actuation member which, when the hooks are inserted into the apertures, engages part of the spring to urge the spring out of engagement with the blocking elements.Type: GrantFiled: November 28, 2006Date of Patent: September 7, 2010Assignee: Autoliv Development ABInventors: Laurent Groleau, Olivier Bertrand, Romain Chebret

Patent number: 7775066Abstract: The invention relates to refrigeration using a thermochemical system based on the coupling of two reversible physico-chemical phenomena between a gas and a solid or liquid sorbent, one at low temperature (the LT phenomenon) and the other at a higher temperature (the HT phenomenon). The LT phenomenon is a liquid/gas phase change of the fluid G or an absorption of the fluid G by a liquid sorbent. The HT phenomenon is a reversible sorption of the fluid G by a liquid or solid sorbent. The endothermic phase of the LT phenomenon takes place in a reactor thermally isolated from the ambient environment. The exothermic phase of the LT phenomenon takes place in a condenser in communication with the reactor in which the HT phenomenon takes place, the condensed fluid G then being transferred to the reactor in which the endothermic phase of the LT phenomenon takes place.Type: GrantFiled: March 12, 2004Date of Patent: August 17, 2010Assignee: Centre National de la Recherche ScientifiqueInventors: Driss Stitou, Olivier Bertrand, Bernard Spinner, Bruno Spinner, legal representative, Caroline Spinner Brossard, legal representative, Anne Christel Spinner Kohler, legal representative, Nathalie Mazet, legal representative, Martin Spinner, legal representative

Publication number: 20040144655Abstract: Process for depositing by electrografting a strong adherent polymer coating onto an electrically conductive surface comprising the step of electrochemical grafting of an active monomer for forming a primer coating P onto the surface and having as general formula: X0 (meth)acrylate wherein X is either part of a preformed polymer or is an intermediate agent for polyaddition reaction or is an anchoring group for attachment of a molecule having at least one complementary reactive group. Such process allows formation of new primer by one-step electro-grafting of a macromonomer. Such process also allows further modification of an initial electrografted polymer to increase the coating thickness by the grafting-from technique. Such process also allows to graft onto the primer coating compounds like functional polymer, peptide, protein, oligonucleotide, dyes, drugs, anti-bacterian compounds.Type: ApplicationFiled: December 4, 2003Publication date: July 29, 2004Inventors: Olivier Bertrand, Robert Jerome, Sandrine Gautier, Veronique Maquet, Christophe Detrembleur, Christine Jerome, Samuel Voccia, Michael Claes, Xudong Lou, David-Emmanuel Labaye

Patent number: 6736769Abstract: To determine a coefficient of diffusion of a radioisotope in a radioisotope-containing implant structure and to calculate a quantity of radioisotope to be introduced in an implant structure in view of administering to a vascular region of a patient's body a dose of radioactivity at a given dose rate, a relation is calculated between a coefficient of diffusion of the radioisotope in the implant structure and a coefficient of diffusion of the radioisotope in the vascular region of the patient's body for at least one given period of time during which the radioisotope has to be released. The diffusion coefficient of the vascular region is determined. The method also determines, from the diffusion coefficient of the vascular region and in connection with the above relation, the diffusion coefficient of the implant structure required to release the radioisotope within the given period of time.Type: GrantFiled: May 9, 2001Date of Patent: May 18, 2004Inventors: Olivier Bertrand, Rosaire Mongrain
