20120228839 | CARRIAGE FOR TRANSPORT OF AN AIRCRAFT ENGINE MODULE - A carriage configured to transport an aircraft engine module from a preparation station to an assembly station includes, on a dolly, a reinforcement structure configured to be made horizontally mobile by sliding on balls, two vertically mobile brackets, and moving fingers to slide under the module's supports. The module is then supported by the carriage in a safe manner, can be raised and transported, and can also be temporarily overturned to check that its interior is empty. | 09-13-2012 |

20080297799 | EVANESCENT WAVE MULTIMODE OPTICAL WAVEGUIDE AND SENSOR WITH HIGH MODE COUPLING - There is provided an evanescent wave multimode optical waveguide sensitive to a chemical species or to a physical parameter. The optical waveguide comprises a core and a cladding having a cladding refractive index lower than that of the core for guiding light to be propagated in the optical waveguide. The cladding defines with the core an optical waveguide providing mode coupling. A chemical indicator is provided in the cladding for causing a variation of the optical absorption of the cladding as a function of the chemical species or the physical parameter. The cladding is interrogated by the evanescent wave of the propagated light. The mode coupling causes unabsorbed light power to be redistributed among the multiple modes while light propagates along the optical waveguide. | 12-04-2008 |
20110007997 | FIBER-OPTIC TEMPERATURE SENSOR ASSEMBLY - A fiber-optic temperature sensor assembly comprises a cap with an inner cavity. A sensor member is received in the inner cavity of the cap. The sensor member has light-transmitting properties adapted to change with temperature variations. An optical fiber has a first end received in the inner cavity of the cap, and a second end of the optical fiber being adapted to be connected to a processing unit for transmitting light signals between the sensor member and the processing unit. A pressing device is received in the cap and pressing against the sensor member such that the sensor member is in operational contact with the first end of the optical fiber for transmission of light therebetween during operation of the fiber-optic temperature sensor assembly. | 01-13-2011 |
20110091150 | EVANESCENT WAVE MULTIMODE OPTICAL WAVEGUIDE AND SENSOR WITH CONTINUOUS REDISTRIBUTION OF OPTICAL POWER BETWEEN THE MODES - There is provided an evanescent wave multimode optical waveguide sensitive to a chemical species or to a physical parameter. The optical waveguide comprises a core and a cladding having a cladding refractive index lower than that of the core for guiding light to be propagated in the optical waveguide. The cladding defines with the core an optical waveguide providing mode coupling. A chemical indicator is provided in the cladding for causing a variation of the optical absorption of the cladding as a function of the chemical species or the physical parameter. The cladding is interrogated by the evanescent wave of the propagated light. The mode coupling causes unabsorbed light power to be redistributed among the multiple modes while light propagates along the optical waveguide. | 04-21-2011 |
