20090055849 | Angle sensor with multi-turn encoding - An angle sensor includes a rotary disc provided with an annular surface divided into cells for encoding the angular position of the disc, the said cells transforming an incident light beam into an optical light signal conveying a code of the said angular position, the said signal being conducted by a light guide to a fixed photodetector connected to means for processing of the said code. | 02-26-2009 |
20100133423 | OUT-OF-ROUND CODER - Device for detection of out-of-round on an angle sensor including a disc supporting angle coding means rigidly attached to a rotating shaft and at least one fixed optical system including a coherent light source emitting a beam interfering with the angle coding means of the support disc in order to code its angular position, means for collimation of the said beam before interference and a photodetector of the modulated beam after interference. In accordance with one possibility, it includes two optical systems arranged 90° from each other. | 06-03-2010 |

20110261465 | DIFFRACTIVE COMBINER FOR MULTICOLOR AND MONOCHROME DISPLAY, METHOD OF MANUFACTURE AND HEAD-UP DISPLAY DEVICE USING SAME - A method for producing a single-layer diffractive combiner for a head-up display having a projection unit with n light sources of λi wavelength(s), where i=1 to n sending light towards the combiner at an angle θp. The method includes forming interference fringes for each λi wavelength on a photosensitive layer with an interference of two light beams from a single laser source of wavelength λe, where the forming step is repeated n times, and each time the forming step is repeated an angle θi between the two beams is determined according to θi=arcsin ((λe/λi)*sin(θp)), one of the interfering beams being divergent and having a spherical wave front and the other being a plane wave, the interference of the beams generating a diffractive network with an adjustable pitch and curved contour fringe lines. | 10-27-2011 |
20110267701 | DIFFRACTIVE HEAD-UP DISPLAY DEVICE PROVIDED WITH A DEVICE FOR ADJUSTING THE POSITION OF THE VIRTUAL IMAGE - A diffractive head up display device that includes a projection unit that uses a display to project an image through a projection window of an image mask, and towards a diffractive combiner. The display and the mask are moveable at right angles to the axis of the projection light beam, so that the adjustment of the position of the virtual image in the field of view of the observer, for example the driver of a vehicle, is obtained by translation of the display and of the mask. | 11-03-2011 |
20120262288 | DIFFRACTIVE SIGNALING DEVICE FOR REAR-VIEW MIRROR WITH 2D/3D DISPLAY - Signaling device designed to be arranged on the reflective element forming a mirror of a rear-view device comprising at least an illumination unit and at least an optical device, characterized by the fact that the optical device includes a symbol generation unit which is provided with at least a diffraction grating designed to form an illuminated image corresponding to a first illuminated symbol, the symbol generation unit being generally transparent and the diffraction grating being formed on the surface of the symbol generation unit without affecting its transparency. | 10-18-2012 |
20130035074 | SYSTEM FOR THE RECORDING AND RETRIEVAL OF VOICE MESSAGES - System for the recording and retrieval of voice messages provided to be arranged in the passenger compartment of an automobile vehicle that includes a control interface, a display screen that displays a list of a plurality of (N) columns for classification of the voice messages according to the subject of their content, each column being selectable by the control interface, a voice message recording device that is controlled by the control interface and makes it possible to record a voice message while associating it with a selected column, a sound emitting device that is controlled by the control interface and makes it possible to emit the voice message or messages recorded in the selected column, and a communications device. | 02-07-2013 |
