Patent number: 10207824Abstract: A photovoltaic generator deployable for a satellite stabilized on three axes. The photovoltaic generator includes an assembly of planar panels articulated with respect to each other, and an attachment arm to the structure of the body of the satellite. In a first or launch position of the photovoltaic generator, the planar panels are folded one over the other. In a second or deployed position of the photovoltaic generator, the planar panels are fully deployed with at least a part of the planar panels being photovoltaic panels. At least one planar panel consists of a thermal radiator, with the radiative face thereof being orientated to be opposite the face of the photovoltaic panels carrying the photovoltaic sensors when the photovoltaic generator is in the deployed position. This radiative face is termed the “shade” face, and the face opposite the panel shaped radiator is termed the “sun” face.Type: GrantFiled: December 15, 2014Date of Patent: February 19, 2019Assignees: AIRBUS DEFENCE AND SPACE SAS, THALES, CENTRE NATIONAL D'ETUDES SPATIALES CNESInventors: Jérôme Lemaire, Yann Miegeville

Patent number: 10200830Abstract: In the context of half-duplex communications in a communication network composed of a plurality of sub-networks associated respectively with supernode devices, a supernode device receiving a floor request: transmits a floor pre-grant message; determines a timer duration according to a distribution law f?(t) for time period between a floor release and the next floor control, and a network-latency distribution law f?(d), so that the probability of subsequent dismissing of the floor control is below a predefined threshold; and broadcasts the data transmitted in the context of the floor control, when the timer has elapsed. When a floor request with higher priority is detected before the expiration of the timer, the supernode device does not broadcast the data and notifies that the floor control is finally refused.Type: GrantFiled: May 22, 2015Date of Patent: February 5, 2019Assignee: AIRBUS DEFENCE AND SPACE SASInventors: Joan Ventura Jaume, Laurent Franck

Patent number: 10184766Abstract: A method and device enable the linear separation of two elements attached to each other through two connecting plates of the first element and the second element respectively. An arrangement connecting and separating the two connecting plates are mixed and comprise a layer. The connecting arrangement comprises soldering, glue, or resin, whereas the separating arrangement comprises thermite. These elements can also be layered rather than mixed. An electrical triggering of this assembly causes its quick and local warming-up and thus enables both of these elements to be separated.Type: GrantFiled: July 31, 2014Date of Patent: January 22, 2019Assignee: AIRBUS DEFENCE AND SPACE SASInventors: Felipe Medina, Luc Preaud

Patent number: 10097461Abstract: Detection of the congestion on a link based on an exchange of messages between a sender and a receiver, one sender and several receivers or several senders and one receiver. This equipment is connected to the ends of a transmission channel. One of the items of equipment is designated as the master and the others slaves. These exchanges are aimed at enabling the master to calculate and compare the rate of the data send and the rate of the data received. A divergence in the rates calculated reveals a congestion on the link. All these exchanges are made in the application layer and therefore do not involve the underlying layers.Type: GrantFiled: October 21, 2011Date of Patent: October 9, 2018Assignee: AIRBUS DEFENCE AND SPACE SASInventors: Claude Poletti, Marc Cartigny, Olivier Klotz

Publication number: 20180227271Abstract: First and second applications are executed in a red domain, and a third application is executed in a black domain, with a lower security level, and via which a ciphered communication tunnel passes between the first and second applications. The first application transmits to the second application a nominal sequence of packets ordered according to their respective sizes; said nominal sequence is intercepted by the third application which, when it wishes to transmit information to the red domain, modifies said nominal sequence by deleting at least one packet, each deleted packet being dependent on said information; on reception of a sequence of packets supposed to be the nominal sequence of packets, the second application checks whether at least one packet has been deleted; and, if such is the case, the second application retrieves said information from the size of each packet thus deleted.Type: ApplicationFiled: August 2, 2016Publication date: August 9, 2018Applicant: AIRBUS DEFENCE AND SPACE SASInventors: Marc CARTIGNY, Olivier KLOTZ, Hervé FRITSCH, Claude POLETTI

Patent number: 9961308Abstract: A multispectral image capture device includes a filter wheel (4) and an image sensor. The filters (41-46) are located close to a focusing plane of a light beam used to form the images, and at least one of the filters is more angularly narrow than the optical field of the image sensor. The production of the filter is thereby facilitated. Advantageously, the filters are closer to one another in the wheel such that multiple filters are in the optical field of the sensor simultaneously. Each multispectral image can be captured more quickly than when each filter covers the entire optical field of the sensor.Type: GrantFiled: December 24, 2014Date of Patent: May 1, 2018Assignee: AIRBUS DEFENCE AND SPACE SASInventor: Pierre-Luc Georgy

Patent number: 9937658Abstract: The invention concerns a method for producing, by welding, a link between an element made from any material, for example metal, and an element made from a thermoplastic-matrix composite material, the second element being produced by depositing a textile yarn pre-impregnated with a thermoplastic material on the surface of the first element. The method mainly includes an operation consisting of producing an interface coating consisting of an epoxy resin filled with a thermoplastic material powder, coating the surface of the element made from any material with same, and leaving the coating to polymerize. It next includes an operation consisting simultaneously of forming the second element and welding same to the coating deposited on the surface of the first element by locally heating the two elements, when depositing the pre-impregnated textile on the first element.Type: GrantFiled: March 26, 2014Date of Patent: April 10, 2018Assignee: AIRBUS DEFENCE AND SPACE SASInventors: Hélène Lebrun, Brigitte Defoort, Dominique Lacour, Audrey Menochet
