Publication number: 20250023729Abstract: A pairing method between a user device (1) and an operator device (2), the user device (1) being intended to receive conditional access data from the operator device (2), the user device having a user device identifier (UID), the operator having an operator device identifier (OID). The method comprises receiving, by the user device, a user device key (KUID) derived from a first cryptographically secure function and receiving, by the operator device, an operator key (KOID) derived from a second cryptographically secure function. The user device comprises a user device bilinear mathematical function (e(KUID, OID)) and the operator device comprises an operator bilinear mathematical function (e(UID, KOID)) which each define a pairing over an elliptic curve.Type: ApplicationFiled: December 8, 2022Publication date: January 16, 2025Applicant: NAGRAVISION SARLInventors: Marco Macchetti, Jerome Perrine, Nicolas Fischer

Patent number: 10855199Abstract: A method of discharging a Modular Multilevel Converter (MMC) includes a plurality of phase legs connected in delta configuration. Each leg includes a plurality of series connected submodules, each submodule including an energy storage. The method includes disconnecting the MMC from an electrical grid, discharging the energy storages by means of a circulating current, and reconnecting the MMC to the electrical grid. The discharging includes, for each phase leg, setting a voltage reference, and sequentially selecting submodules in zero state by means of a sorting algorithm for switching each of the selected submodules to plus or minus state until the voltage deviation from the set voltage reference of the energy storage of each submodule in the phase leg is within a predefined range.Type: GrantFiled: December 18, 2015Date of Patent: December 1, 2020Assignee: ABB Power Grids Switzerland AGInventors: Beat Buchmann, Jerome Fischer

Patent number: 6881434Abstract: A process for improving the knot tensile strength of a braided suture while maintaining its first throw holding characteristics includes the steps of applying a biocompatible co-polymer to the braided suture and then heating the suture to a temperature above the flow point of the co-polymer. An outer coat is applied to the suture after the heating step. The suture may be scoured with a solvent before the co-polymer is applied or the co-polymer may be applied simultaneously with the scouring step. The co-polymer preferably comprises one or more lactones, more preferably, ?-caprolactone and glycolide. This process may be used with bioabsorbable sutures, such as those comprising filaments made of polyglycolide and polylactide.Type: GrantFiled: July 31, 2002Date of Patent: April 19, 2005Assignee: Ethicon, Inc.Inventors: Henry Pokropinski, Jr., Howard Scalzo, Jerome A Fischer
