20130226395 | SYSTEM FOR DETECTING THE FIRST SIGNS OF A MALFUNCTION OF AN AIRCRAFT ENGINE VALVE - A method and a system for detecting the first signs of malfunction of an aircraft engine valve, including an acquisition device to acquire the output pressure measurements of the valve, and contextual and command data of the valve, a processor to define a set of indicators of the first signs of malfunction, according to the output pressure measurements and the contextual and command data. A set of estimators corresponding to the set of indicators of the first signs of a malfunction, is determined using a previously produced regression model. At least one distance between the set of indicators and the set of estimators is computed. The distance is compared to a threshold of the first signs of a malfunction, in order to detect the first signs of malfunction of the said valve. | 08-29-2013 |
20150021455 | TURBINE ENGINE SUPPORT PART OF HYBRID STRUCTURE - A turbine engine support part including a main structure made of composite material and a reinforcing secondary structure made of metal and integrated in the main structure, the secondary structure presenting a geometrical shape and dimensions configured to impart mechanical strength to the support part in event of the main structure being destroyed. | 01-22-2015 |

20150293498 | SELF-REFERENCE HOLOGRAPHIC IMAGING SYSTEM - A system for recording a digital hologram of an object comprises: a coherent source intended to illuminate the object and thus produce a wave diffracted by the object; and a digital sensor intended to record the digital hologram of the object. It furthermore comprises a spatial phase modulating assembly able to produce in the plane of the sensor a plurality of duplicates of the wave diffracted by the object, the duplicates being offset from each other but overlapping partially, these duplicates forming on the sensor a digital hologram of the object, this hologram being what is referred to as a self-reference hologram. | 10-15-2015 |
