An optical device with at least one interconnection tab is provided. The optical device includes a pair of opposed substrates with a gap therebetween filled with an electro-optic material. Each substrate has a facing surface with a substrate electrode disposed thereon. A sealing material is disposed between the pair of opposed substrates to contain the electro-optic material. At least one interconnection tab is interposed between the substrates. The interconnection tab includes an insulator layer with opposed surfaces. A tab electrode is provided on each surface, wherein each tab electrode is in electrical connection with a corresponding substrate electrode facing the tab electrode. And a pad electrode is also provided on each surface, wherein each pad electrode is in electronic connection with the substrate electrode facing the opposed surface of the insulator layer.

Interconnection tab used with optical devices

A goggle includes a lens assembly which comprises a front lens, a rear lens spaced apart from the front lens, and a liquid crystal device disposed on one of the lenses. The goggle includes a frame, which defines an aperture and a peripheral channel. The peripheral channel receives the front lens and the rear lens is positioned rearward of the channel so that the aperture receives the lens assembly. A power unit includes a battery and a drive circuit, wherein the drive circuit is connected to a pair of prongs that are electrically connectable to the liquid crystal device for operation thereof. The power unit provides a master switch connected to the battery to control application of power to the drive circuit, and a state change switch to control application of power from the drive circuit, through the prongs, to the liquid crystal device.

Power unit assembly for use with a liquid crystal eyewear device

An electro-optic eyewear assembly having a frame with opposed ends, a pair of temples, and a hinge mechanically interconnecting each temple to a corresponding end of the frame. Each temple moveable between a wearing position and a storage position and at least one electro-optic lens carried by the frame and a control circuit carried by at least one of the temples. The electrical connection between the control circuit and the at least one electro-optic lens being made by moving one of the temples into physical contact with the frame when the temple carrying the control circuit is moved to a wearing position.

Eyewear incorporating lenses with electronically variable optical properties

An optical device with at least one interconnection tab is provided. The optical device includes a pair of opposed substrates with a gap therebetween filled with an electro-optic material. Each substrate has a facing surface with a substrate electrode disposed thereon. A sealing material is disposed between the pair of opposed substrates to contain the electro-optic material. At least one interconnection tab is interposed between the substrates. The interconnection tab includes an insulator layer with opposed surfaces. A tab electrode layer is provided on each surface, wherein each tab electrode layer contacts a corresponding substrate electrode. And each tab electrode layer includes a portion that extends from the pair of opposed substrates on selected portions of the insulator layer.

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.

Curved optical device and method for making the same

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 maybe a liquid crystal to provide the optical device with enhanced optical properties.
