| 20100083655 | TURBOCHARGER SYSTEM AND METHOD - A turbocharger system for an engine (e.g., a diesel engine in a locomotive) includes a turbocharger unit and a fixed gear assembly. The turbocharger unit comprises a compressor for providing compressed air to an intake of the engine, a turbine driven by an exhaust of the engine, and a shaft interconnecting the turbine and compressor. The fixed gear assembly interconnects an engine gear train of the engine to the turbocharger unit for driving the turbocharger unit. There is no turbocharger clutch mechanism in the turbocharger system, engine, or otherwise in the vehicle. Thus, the fixed gear assembly operates to drive the turbocharger unit whenever the engine gear train is operational. | 04-08-2010 |

| 20090051928 | Method for analyzing a wavefront through frequency difference multilateral interferometry - The method comprises positioning a diffraction grating with a two-dimensional meshing on the path of the beam to be analyzed and processing at least two interferograms of at least two different colors, each interferogram being obtained in a plane from two sub-beams with different diffraction orders. The invention can be used to analyze and correct divided wavefronts. | 02-26-2009 |
| 20090201512 | Compact achromatic optical interferometer of the three-wave lateral shearing type - A method and a system for analyzing the wavefront of a light beam, wherein a diffraction grating is arranged in a plane perpendicular to the light beam to be analyzed and optically conjugated to the analysis plane. Different emerging beams of the grating interfere to generate an image having deformations linked to the gradients of the wavefront to be analyzed. | 08-13-2009 |
| 20090262364 | METHOD, PHASE GRATING AND DEVICE FOR ANALYZING A WAVE SURFACE OF A LIGHT BEAM - The application relates to a method for analyzing the wave surface of a light beam from a source to the focus of a lens. The beam illuminates a sample on the analysis plane and having a defect. A diffraction grating of the plane is a conjugate of an analysis plane through a focal system. An image is formed in a plane at a distance from the grating plane and analyzed by processing means. The invention encodes this grating by a phase function resulting from the multiplication of two phase functions, a first exclusion function defining a meshing of useful zones transmitting the beam to be analyzed in the form of light pencil beams, and a second phase fundamental function which creates a phase opposition between two light pencil beams coming out of adjacent meshes of the exclusion grating. | 10-22-2009 |

| 20090253371 | MODULAR DEVICE FOR TURNING ON THE POWER SUPPLY OF AN ELECTRONIC ITEM OF EQUIPMENT IN A SECURE MANNER - The present invention relates to a device making it possible to turn on a sub-assembly of an electrical item of equipment hosted in a bigger system, which, if turned on unchecked, may impair the operation of the other items of equipment of the system. An embodiment includes three make/break switches in series in the power supply line and a control of the opening or closing of these make/break switches. Two of the make/break switches are controlled by two independent discrete state indicators, to determine whether the power supply of the sub-assembly of the item of equipment may be energized without undue risk to other equipment of the system. The third make/break switch is controlled by a validation command based on the two discretes, actuating the third make/break switch only if the discretes are in the desired state and if a switching of these discretes has been noted. An embodiment of the invention applies to the protection of the onboard equipment of an aircraft in the flight phase against the turning on of ancillary equipment not used in the flight phase and transmitting radioelectric waves that may catastrophically impair the operation of the other items of equipment. | 10-08-2009 |
