  • Patent number: 7887201
    Abstract: A low-glare motor-vehicle includes a color reproduction index Ra of at least 70 and a reduced reflection for each of the illuminants A and C in scotopic vision (at night) as compared with photopic vision (in the daylight) by at least 3%. In one embodiment, the mirror consists of a transparent substrate, a thin transparent metallic layer, an adapted dielectric layer and the reflector properly speaking.
    Type: Grant

  • Patent number: 6369935
    Abstract: The invention concerns an electrochromic glazing system, with an electrochromic pane unit and at least one other pane, which are joined to one another in the edge area by means of a spacer frame, forming an interspace, and with a temperature sensor for detection of the temperature of the electrochromic pane unit. To optimize its location, according to the invention the temperature sensor is arranged in the region of the spacer frame, between the electrochromic pane unit and the other pane. The invention takes advantage of the fact that the spacer frame area represents a thermal bridge between the panes of a double-glazing unit which is especially suitable for the arrangement of a temperature sensor.
