  • Patent number: 9942432
    Abstract: A scanning device includes a transparent platen which receives a sheet to be scanned. A backing assembly is spaced from the platen by the sheet during scanning. The backing assembly includes a backing plate of a fixed color and an electrochromic layer intermediate the backing plate and the platen. The electrochromic layer has a first state in which the electrochromic layer is opaque and has a different color from the fixed color, and a second state, in which the electrochromic layer is transparent to expose the backing plate through it. A sensor is positioned to acquire an image of the sheet based on light passing through the platen. A controller selectively applies a voltage across the electrochromic layer to change the electrochromic layer between the first and second states.

    Abstract: The present invention relates to a photovoltaic cell device with combined energy conversion and lighting option and a method a controlling such a device. It comprises a responsive element, a reflector or a light source for changing light absorption and thus appearance of photovoltaic cells (e.g. solar panel). It is also possible to combine the responsive element or the reflector with light source(s) providing extra illumination. When combined with a sensor and control unit, ambient intelligent solar panels and ambient intelligent lighting systems can be obtained. A combination of a luminescent solar concentrator (LSC) and light-emitting device is also possible, where an energy storage device is charged by a photovoltaic cell upon irradiation. The energy storage powers one or more light sources which are coupled to the sides of the luminescent plate. The light emitted by the light sources is coupled into the plate and (partly) converted by the luminescent plate.
