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 |
20130033463 | INDEXING AND HOLOGRAPHIC DISPLAY SYSTEM FOR MANUAL CONTROL INTERFERENCE - Manual control interface including: a movable part, a photo-detector, a movable holographic element including a first series of holograms forming coding motifs of the selection position of the movable part, characterized by the fact that the movable holographic element includes a second series of holograms forming figurative motifs representing the functions of the apparatus, the position of the movable holographic element relative to the support determining the figurative motif which is illuminated by a suitable light beam, so as to project the figurative motif corresponding to the selected function towards a display zone visible to the user. | 02-07-2013 |
20140126177 | CONTROL PANEL INCLUDING A RESISTIVE-TYPE BACKLIT KEY - A control panel including a cover which is provided with at least one tactile pressure detection zone forming a control button, in which a force sensor is arranged between the cover and a support, behind the detection zone, in which a spacer made of elastically compressible material is mounted between the force sensor and the cover so as to take up the mechanical plays between the force sensor and the cover, characterized by the fact that the spacer is at least partially translucent and by the fact that the control panel includes at least one main light source and a light collector which permits injection of the light produced by the said main light source into the thickness of the spacer so that the spacer produces a backlighting beam directed towards a zone to be illuminated of the detection zone. | 05-08-2014 |
