| 20110025702 | Method of Constructing Images for an Imaging Appliance - In an imaging appliance with display of the colour sequential type, a spatially monochrome image is displayed by preparing, for each complete image to be displayed, a sequence of monochrome images comprising an image for each colour of the light box, the monochrome images of the sequence being such that a pixel that is lit in one colour is off in the other colour(s), so that there is no colour break effect. Certain areas of the display can be reserved, in which the pixels are controlled in the usual way so as to use the entire colour palette of the display, for example to display a colour video image. The invention applies notably to the head-up imaging appliances applicable in onboard navigation systems, and to the imaging appliances for direct viewing. | 02-03-2011 |

| 20090119058 | Displacement Speed Measurement Method - The measurement method of the displacement speed of a moving element with respect to a fixed element is performed by means of an optic measuring device comprising a first reference sensor and a plurality of distinct second measurement sensors substantially aligned along the axis of movement of the moving element. The measurement method comprises determination of estimated speeds by correlation of the signals supplied by the reference sensor and each of the measurement sensors, and calculation of a mean speed of said estimated speeds. | 05-07-2009 |
