Abstract: A cell for the electronic attenuation of light suitable for use in eyewear includes spaced substrates coated with a conducting layer, and preferably a passivation layer and an alignment layer. Disposed between the substrates is a guest-host solution comprising a host material and a light-absorbing dichroic dye guest. A power circuit is provided with a power supply connected to the conducting layers. Adjustment of the power supply alters the orientation of the host material which in turn alters the orientation of the dichroic dye. Light is absorbed by the dichroic dye, depending upon its orientation without the need for polarizers.

Abstract: A splicing asymmetric reflective array (10) for combining at least two input beams (12, 14) into a combined output (16). The arrays include a plurality of substantially reflecting, adjacently positioned layers (20). Each layer (20) has substantially the same width (24) and substantially the same thickness (22) while having a different height dimension (26). A collective entry portion (40) is formed by the adjacent layers' width and thickness dimensions, wherein at least two input beams are directed into and received therein. A collective exit portion (42) is formed by the adjacent layers' height dimensions, wherein the height dimensions are monotonically increasing. A cascade array (60) incorporating the array 10 and reduced size arrays (64, 66, 68, and 70) may be used to combine more than two input beams into one. A three-dimensional array (80), which alters the slope of each layer's height dimension, can be used to combine four input beams (82) into one output beam (84).

Abstract: A device (100, 140, 150) for differentially absorbing light, depending on the state of linear polarization of the light, is disclosed. This polarizing effect is induced and controllable by the level of ambient light impinging on the device. The device (100) includes a carrying medium which may be a film (142) or opposed substrates (112) that are sealed. A film or the opposed substrates carry a mixture (120) of fluid material (124), which is preferably a liquid crystal and photochromic dyestuffs (122), wherein the photochromic material is activated upon the detection of ultraviolet light so as to absorb some of the light and wherein the energization of the photochromic (100) material effects the material so as to simultaneously selectively absorb the specularly reflected sunlight while permitting all light to pass in dimly lit environments. The device (150) may allow for electrical control of the absorptive properties.

Abstract: A device ( 100, 140, 150 ) for differentially absorbing light, depending on the state of linear polarization of the light, is disclosed. This polarizing effect is induced and controllable by the level of ambient light impinging on the device. The device ( 100, 140 ) may be used as an anti-glare vision protection device which selectively absorbs specularly reflected sunlight in brightly lit environments while permitting all light to pass in dimly lit environments. The device ( 100 ) includes a carrying medium which may be a film ( 142 ) or opposed substrates ( 112 ) that are sealed. A film or the opposed substrates carry a mixture ( 120 ) of fluid material ( 124 ) and photochromic dyestuffs ( 122 ), wherein the photochromic material is activated upon the detection of ultraviolet light so as to absorb some of the light and wherein the energization of the photochromic material effects the material so as to simultaneously selectively absorb the specularly reflected sunlight. The material ( 124 ) may be any fluid that dissolves the photochromic dyestuff material ( 122 ). The fluid is preferably a liquid crystal material such as nematic or chiral nematic. Alternatively, the material ( 124 ) may be a polymer liquid crystal. The device ( 150 ) may allow for electrical control of the absorptive properties.
