Abstract: A device for managing a surplus of power of a photovoltaic generator that supplies power to electrical appliances connected to the photovoltaic generator, the surplus of power being the difference between the maximum potential electrical power that the photovoltaic generator could produce at a given time taking into account its illumination, and the electrical power actually consumed at that time by the electrical appliances. The device includes a photoelectric control sensor to measure solar light intensity received by the photovoltaic panels and to deduce the maximum potential electrical power; a means for determining the surplus of available power between the value of the maximum potential electrical power and the value of the electrical power actually consumed by the electrical appliances; and a means for managing the surplus of available power, the means being configured to redirect and distribute the surplus of available power between the electrical appliances.

Abstract: 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-colored 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 color saturation of the image.

Abstract: 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.

Abstract: 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.

Abstract: 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.

Abstract: 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.
