US Classification:

359/265000, 359/254000, 359/251000, 359/252000

Abstract:

Edge busbars on a substantial perimeter of an electrochromic device are disclosed having electrical paths wrapping over the perimeter edge. Internal busbars interior from the perimeter are disclosed which lower the conductivity of the conductive layer of an electrochromic device. Signals supplied to the busbars to control the electrochromic device are controlled by a switching power supply that allows the maintaining of the color of the electrochromic device without application of continuous power.

International Classification:

B05C001/00

US Classification:

118/401000, 118/244000

Abstract:

Liquid film dies for coating of substrates with thin films of fluid have substantially constant fluid path geometry fluid passages leading to fluid outlet orifices. A fluid film applicator for applying a film of a fluid onto a substrate includes a dispensing head which dispenses the fluid so that the fluid is deposited as a continuous sheet on the substrate, and a meniscus forming member that controls the thickness of the fluid in the continuous sheet. The dispensing head may include upper and lower plates with a fluid channel between, the plates being offset and positioned relative to the meniscus former. A variable contour dispensing head has movable dispensers which feed coating fluid to a common slot, and the slot can be deformed to correspond to the shape of the surface being coated.

US Classification:

435/287200, 438/001000

Abstract:

This invention describes the advantages of forming integrated biochips including microarrays comprised of tiled assemblies. For a given biochip of this invention, the tiles may have similar or dissimilar properties. Novel, high-speed manufacturing processes are described to assemble such biochips. A preferred embodiment is the use of micro-machined feeders for placing the tiles in the assembly process.

International Classification:

G02F001/15

US Classification:

359/265000

Abstract:

A transparent chromogenic assembly in which color changes are selectively effectable over predefined areas comprises a pair of facing transparent substrates () each covered with a conductive layer divided into individual energizeable areas each provided with a set of busbars (). A passive layer may be superimposed over one of the substrates, its color being chosen so that the color and the transmissivity of the passive layer accommodates the range of color change and transmissivity of the electrochromic layer to maintain the transmitted color of the panel in a warm or neutral shade. Various other chromogenic windows, devices and systems are also disclosed.
