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 curved optical device includes a pair of initially flat opposed flexible substrates that may have a fluid material with spacers disbursed therein disposed between the pair of substrates and sealed. The substrates have a uniform controlled distance therebetween. The substrates are permanently curved by applying heat and pressure with a mold while maintaining the controlled distance therebetween. The fluid material may be a liquid crystal to provide the optical device with enhanced optical properties.

Abstract:
A method of constructing a curved optical device includes assembling of at least one cell having opposed flexible substrates with a controlled distance therebetween to form a gap adapted to receive a fluid. The process continues by holding only a portion of the cell in a fixture, positioning a curved mold surface proximal the cell and heating at least one of the curved mold surface and cell. Next, the cell is conformed to the mold surface so that the cell substantially retains the curved shape when the heat and the mold surface are removed.

A solar powered variable light attenuating device includes a liquid crystal cell, a photovoltaic cell in electrical communication with the liquid crystal cell, and a light concentrator having a light absorbing surface and a light emitting surface optically coupled to the photovoltaic cell. At least a portion of light impinging on the light absorbing surface of the light concentrator is concentrated and directed through the light emitting surface to a photon-absorbing portion of the photovoltaic cell to generate a voltage. The generated voltage is used to change the liquid crystal cell from a de-energized state to an energized state in response to sunlight directed toward the photovoltaic cell.
Abstract:
An electronically dimmable optical device, including, in sequence, an active absorbing polarizer; a first static reflective polarizer; an active polarization rotator; and a second static reflective polarizer; configured so that the reflectivity and/or transmissivity of the device can be controlled (increased or decreased) by application of a voltage across the active absorbing polarizer and/or the active polarization rotator. One or more polarization levels can be selected by controlling the voltage at the active absorptive polarizer such that setting the active absorptive polarizer to a selected polarization level determines the brightness of an image produced by the device.
