| 20110231125 | AIRCRAFT STRUCTURE TESTING DEVICE OF THE WIRE CUTTER TYPE - A detection wire cutter including a conducting wire mechanically secured to a structure that is to be monitored. This wire is electrically powered at one end and at another end feeds back an electrical voltage corresponding to the power supplied, provided that the structure that is to be monitored has not undergone unacceptable mechanical damage. As an improvement, two arrays of wires extending over flat supports in two directions in space are proposed. Each array is powered by a distinct network electrical supply. The two networks extend in layers, with parallel wire portions. The position of a crack does not impede the passage of current between certain terminals, but certain other terminals will no longer receive any current because the crack has broken a network supply general connection between the connection of one wire and that of another. | 09-22-2011 |
| 20110185245 | METHOD FOR DETECTING AND CORRECTING ERRORS FOR A MEMORY WHOSE STRUCTURE SHOWS DISSYMMETRICAL BEHAVIOR, CORRESPONDING MEMORY AND ITS USE - To produce a memory which resists ion or photon attack, a memory structure is chosen whose memory point behaves asymmetrically with regard to these attacks. It is shown that in this case, it is sufficient to have a reference cell for an identical and periodic storage structure in order to be able to correct all the memory cells assailed by an attack. An error correction efficiency of ½ is thus obtained, with a simple redundancy, whereas the conventional methods make provision, for the same result, to triple the storage, to obtain a less beneficial efficiency of ⅓. | 07-28-2011 |

| 20110046996 | METHOD FOR DETERMINING THE OPERATING FORECAST FOR A SYSTEM - According to the invention, to determine an operating forecast for a system, measurements are taken of an environmental value in an environment surrounding the system. Then these measurements are processed in a processing unit in order to determine how much of the system's lifetime has been consumed. The consumed lifetime is based on a history of the system in the environment. This is used to calculate a forecast of a good operating lifetime. According to the invention, this forecast determination is made by adaptive linear regression. Thus, all forecast calculations are simplified and can be performed by the system itself and in real-time. | 02-24-2011 |

| 20100278586 | STRUCTURAL CONNECTING ROD MADE OF A COMPOSITE AND PROCESS FOR PRODUCING SUCH A CONNECTING ROD - A connecting rod is composed of two or more assembled shells made of a composite, open over the entire length of the connecting rod. The shells incorporate clevis joints for introducing stress at each of their ends. The shells are produced separately then assembled together to form a sealed section. Each shell is made from a material preimpregnated with long fibres. The production of each shell is simplified due to the overall shape of the shell as a simple curve, thus a shell may be produced industrially, for example, by thermoforming a flat composite preform. The two shells are assembled by simultaneous polymerization of the shells, by bonding, by welding, by riveting or any other assembly process or combination of assembly processes that are compatible with one another. The structural composite connecting rod obtained has very good mechanical properties, especially in compression, with a simple and economic production process. | 11-04-2010 |

Each trim panel is either an active panel including actuators powered by the active noise control system or a passive panel without such actuators. In addition, the trim panels of the cabin of the one type, either active or passive, are mechanically interchangeable with a panel of the other type, either passive or active, respectively. Power supply wiring for active panels is installed in the aircraft, this wiring being capable of powering all active panels which could be installed, whether said active panels are actually installed or whether interchangeable passive panels are installed. Finally, a power supply system for the active panels is installed in the aircraft and connected to the power supply wiring of the active panels. | 10-07-2010 |
