20120236540 | Display Device with Integrated Photovoltaic Cells, with Improved Luminosity - A display device, in particular digital display screen, with integrated photovoltaic cells, including (a) an array of image zones emitting light or backlit by a light source placed behind the array of image zones, (b) an array formed by a plurality of photovoltaic cells and a plurality of orifices, in which array two neighboring photovoltaic cells form an orifice, and (c) a lenticular array making it possible to focus the light emitted by the image zones into the orifice between two neighboring photovoltaic cells. The lenticular array of the display device is positioned between the array of image zones and the array of photovoltaic cells. | 09-20-2012 |
20140253613 | DISPLAY DEVICE INCLUDING A MULTIFUNCTIONAL AND COMMUNICATING SURFACE - The invention relates to a display device including a plurality of pixels forming an image, and an optical plate arranged opposite the image and having transparency areas configured to allow the light from the pixels to at least partially pass therethrough. The optical plate further includes at least one array of functional elements corresponding to an electronic and/or mechanical function. The functional elements are inserted between the transparency areas and arranged such that the light emitted by the pixels is directed so as to pass through the transparency areas without intercepting the arrays of functional elements, so as to render the arrays of functional elements invisible or quasi-invisible to an observer of the display device. The invention can be used in any type of display device in which functions other than display itself must be integrated in a visually discreet manner. | 09-11-2014 |
20140290723 | RIGID OR FLEXIBLE SOLAR COLLECTOR HAVING A SURFACE-DISPLAYED IMAGE, AND METHODS FOR MANUFACTURING SAID SOLAR COLLECTOR - A device includes at least one collector of light energy and a transparent plate between the light source and the collector. One surface of the transparent plate has slits, enabling the device to be flexible about an axis parallel to the slits, while another surface contains image pixel areas and transparency areas. An observer can display an image on the surface of the screen even though the screen is transparent to the rays of the sun, which reach a solar collector behind the plate. The slits have the optical property of increasing the angles for viewing the image. The invention is particularly suitable for visually integrating the solar collectors into the environment in a general manner on any medium with images, including electronic images, and on any planar or non-planar surfaces. | 10-02-2014 |
20140299175 | RIGID OR FLEXIBLE SOLAR COLLECTOR WITH AN IMAGE DISPLAYED ON THE SURFACE AND METHODS FOR PRODUCING SAME - A device with a collector for collecting light energy from a light source includes a transparent plate between the light source and the collector, whereof a first face is structured by an array of lenses separated by slots, while the second face contains areas of pixels, and transparent areas. An observer can view an image on the surface of the screen, even though the screen is transparent to solar radiation. This solar radiation reaches a solar collector behind the plate. The slots are provided in the thickness of the plate and have the effect of making the screen flexible and rollable about an axis. These slots also have the optical property of increasing the angles of view of the image. This invention is particularly suitable for the visual integration of solar collectors into the environment, generally on any imaged media, including electronic images, and on any planar or non-planar surfaces. | 10-09-2014 |
20140320990 | SOLAR CONCENTRATOR INCLUDING A HELIOSTAT AND A FRESNEL LENS - An heliostat includes a plane mirror and a first axis of rotation which is positioned parallel to the axis of rotation of the Earth. The solar radiation reflected by the mirror is permanently oriented toward a stationary Fresnel lens which is perpendicular to the first axis of rotation and which concentrates the solar radiation toward a stationary target. A solar field is composed of a plurality of heliostats according to such characteristics and all the first axes of rotation of which are rotated by a mechanical linkage coupled to a rod which is moved by a single motor. This arrangement reduces the total cost of the installation. | 10-30-2014 |
20150035849 | METHOD FOR IMPROVING THE VISUAL QUALITY OF AN IMAGE COVERED BY A SEMI-TRANSPARENT FUNCTIONAL SURFACE - This invention describes a method for improving the visual rendering of an image when said image is placed behind a semi-transparent functional surface. The method consists of modifying certain features of the original image, in particular the brightness, contrast, gamma and colour saturation thereof, in such a way that the visual rendering of the image modified in this way and placed behind the semi-transparent functional surface is closer to the rendering of the original image when said image is seen alone, without the semi-transparent functional surface. | 02-05-2015 |
20150083195 | TRANSPARENT SOLAR ENERGY COLLECTOR - The invention concerns a device for collecting infrared solar radiation by heating a circulating blade of air circulating between two transparent glazed walls. The first glazed wall polarises light in a circular manner. The second glazed wall reflects infrared radiation towards the first glazed wall. The infrared radiation which has been reflected has changed polarisation direction and is then absorbed by the first glazed wall which heats up, and in turn heats the circulating blade of air in contact with same. | 03-26-2015 |
20150214406 | DEVICE FOR IMPROVING THE QUALITY OF AN IMAGE COVERED WITH A SEMITRANSPARENT PHOTOVOLTAIC FILM - Problem addressed: how to decrease the loss of visual quality in an image that appears when this image is placed behind a semitransparent photovoltaic sheet or film. Solution: on the one hand, increase the luminosity of the image by depositing a white-coloured or metallic or reflective layer on the side of the photovoltaic cells that is turned towards the image; and on the other hand, by modifying the luminosity, the contrast, and the colour saturation of the image. | 07-30-2015 |
