Abstract:
A reflective element assembly for a variable reflectance vehicular mirror includes a front substrate having a transparent conductive coating disposed on a second surface, and a rear substrate having a third surface conductive coating disposed on its third surface and preferably, a fourth surface conductive coating disposed on its fourth surface. At least a portion of the third surface conductive coating may wrap around an edge portion of the rear substrate and at least a portion of the fourth surface conductive coating may wrap around at least a second portion of the perimeter edge so as to establish electrical continuity between the fourth surface conductive coating on the fourth surface and the third surface conductive coating on the third surface. The rear substrate may have a smaller dimension than the front substrate so as to provide an overhang region, preferably at the wraparound region.
Abstract:
Optical devices, are provided, having a first conductive layer, an optical layer, arranged over the first conductive layer, and a second conductive layer, arranged over a portion of the optical layer, in accordance with a predetermined pattern. The optical layer is transparent to at least a wavelength of interest and has an index of refraction, which is a function of a variable, substantially reversible, dopant concentration or dopant concentration gradient in it. By applying an electric potential between the first and second conductive layers, a change in the index of refraction is formed within the optical layer, between the portion abut with the predetermined pattern and the remainder of the optical layer. Additionally, the present invention provides optical devices formed as stacks of layered constructions, each layered construction comprising a first conductive layer, an optical layer, arranged over the first conductive layer, and a second conductive layer, arranged over the optical layer, these layered constructions being operable as tunable interference filters.
Abstract:
A rearview mirror assembly for a vehicle comprises an electro-optic mirror unit 22 whose reflectivity is variable in response to an electrical voltage applied thereto and an electrical circuit (34) for controlling operation of the mirror unit in response to one or more one light sensors. A bracket (30) for supporting the mirror unit from an interior portion of the vehicle via interengaging ball and socket members (32, 33) allows angular adjustment of the mirror unit. The ball member (33) includes a plurality of electrical contacts (134a, 134b) on an exposed surface thereof for sliding engagement by respective counter-contacts (102a, 102b) over a range of angular movement of the mirror unit for supplying power to the electrical circuit from a vehicle electrical system external to the mirror assembly.
