  • Patent number: 9809492
    Abstract: The invention relates to a substrate (30) coated on one face (31) with a multilayer of thin films (34) comprising at least one metal functional layer (140) based on silver or made of silver and two antireflective coatings (120, 160), the said antireflective coatings each comprising at least one antireflective layer (124, 164), the said functional layer (140) being disposed between the two antireflective coatings (120, 160), characterized in that the said metal functional layer (140) is a discontinuous layer having a surface area occupation factor in the range between 50% and 98%, or even between 53% and 83%.

  • Patent number: 9226366
    Abstract: The present invention relates to a lighting control system, comprising a control unit comprising a memory in which control programs are recorded. The control programs are capable of controlling the optical transmission through an active window pane with electro-controllable optical transmission properties and are capable of controlling an electro-controllable lighting device. The system furthermore comprises a coloration sensor for measuring a value representative of a coloration of the light. The control programs are capable of controlling the lighting generated by the lighting device as a function of the value supplied by the coloration sensor.

  • Publication number: 20140060887
    Abstract: A transparent electric conductor includes titanium oxide doped with aluminum and at least one other dopant: either in the form Ti1-a-bAlaXbOy, where X is a dopant or a mixture of dopants selected from the group consisting of Nb, Ta, W, Mo, V, Cr, Fe, Zr, Co, Sn, Mn, Er, Ni, Cu, Zn and Sc, a is in the range 0.01 to 0.50, and b is in the range 0.01 to 0.15; or in the form Ti1-aAlaFcOy-c, where a is in the range 0.01 to 0.50, and c is in the range 0.01 to 0.10. With the above composition, the electrical conductivity and the light transmittance are suitable for use of the transparent electric conductor in various applications, in particular as a transparent electrode of an electronic device.

  • Publication number: 20130258484
    Abstract: The present invention relates to a system for controlling the optical transmission of a plurality of windows Vk with electro-controllable optical transmission properties, comprising at least one spatial brightness sensor for supplying at least one value representative of brightness respectively for different spatial areas forming subsets Xi of a set X and thus supplying a mapping L of a brightness in which the subsets Li of L are associated with the sets Xi, and a control unit comprising a memory in which programs are stored which are capable of controlling the optical transmission of each of said windows.
