A method for managing UV irradiation for curing a semiconductor substrate, includes: passing UV light through a transmission glass window provided in a chamber for curing a semiconductor substrate placed in the chamber; monitoring an illuminance upstream of the transmission glass window and an illuminance downstream of the transmission glass window; determining a timing and / or duration of cleaning of the transmission glass window, a timing of replacing the transmission glass window, a timing of replacing a UV lamp, and / or an output of the UV light based on the monitored illuminances.

Prior electrochromic devices frequently suffer from high levels of defectivity. The defects may be manifest as pin holes or spots where the electrochromic transition is impaired. This is unacceptable for many applications such as electrochromic architectural glass. Improved electrochromic devices with low defectivity can be fabricated by depositing certain layered components of the electrochromic device in a single integrated deposition system. While these layers are being deposited and / or treated on a substrate, for example a glass window, the substrate never leaves a controlled ambient environment, for example a low pressure controlled atmosphere having very low levels of particles. These layers may be deposited using physical vapor deposition.

A Fresnel lens including a substantially polygonal focusing portion adapted to focus solar radiation to a area having the same geometry as the focusing portion of the lens. Also a solar module including the Fresnel collecting lens and a substantially polygonal photovoltaic cell. The photovoltaic cell is mounted at distance from the Fresnel collecting lens so that the size of the area substantially matches the size of the photovoltaic cell. Also a solar panel having multiple modules within a glazed building envelope system. The solar panel also includes an actuating mechanism within the glazed window envelope system. The actuating mechanism is operatively connected to the plurality of solar modules and is adapted to move the solar modules to track the sun.

An electro-optical glazing structure having reflection and transparent modes of operation for selectively reflecting and transmitting electromagnetic radiation without absorption, respectively. The electro-optical glazing structure comprising: an electro-optical panel having first and second optical states of operation; a composite broad-band infrared (IR) reflective polarizing filter structure of electrically-passive construction, mounted to the electro-optical panel; and an optical state switching mechanism for switching the electro-optical panel to the first optical state of operation in order to induce the electro-optical glazing structure into the reflection mode of operation, and for switching the electro-optical panel to the second optical state of operation in order to induce the electro-optical glazing structure into the transparent mode of operation. When the electro-optical panel is switched to the first optical state of operation, electromagnetic radiation within a first prespecified bandwidth falling incident upon the electro-optical panel is reflected from the electro-optical panel without absorption. When the electro-optical panel is switched to the second optical state of operation, electromagnetic radiation within a second prespecified bandwidth falling incident upon the electro-optical panel is transmitted through the electro-optical panel without absorption. By virtue of the present invention, the glazing structure is capable of providing both thermal insulation as well as privacy functions.

A monolithic patterned dichroic filter array is mounted on a wafer by combining microelectronic and microlithography techniques. A wafer is coated with a photoresist. The assembly is masked, and the unmasked photoresist, after exposure to ultraviolet light, is developed to expose a predetermined section. That section of wafer is then over developed to create an undercut in its walls and to expose the underlying wafer. Dichroic filter material is then deposited onto the wafer by a cold process, and the photoresist layer is then removed, leaving only the dichroic filter material on the wafer. The process is repeated to create an array. The finished wafer is then bonded to a linear or two dimensional detector array, or to a glass window that is then bonded to a linear or two dimensional detector, to create a high performance spectral detector for spectroscopic imaging. When placed on a two dimensional detector in a camera, an imaging system capable of showing spatial variation in color, chemicals or other spectrally dependent parameters is produced.

Provided is a transparent and light-weight ballistic resistant safety glazing comprising an ionomer sheet. The ionomer sheet comprises an ionomer derived from a parent acid copolymer that comprises copolymerized units of an α-olefin having 2 to 10 carbon atoms and, based on the total weight of the acid copolymer, about 20 to about 30 wt % of copolymerized units of an α,β-ethylenically unsaturated carboxylic acid having 3 to 8 carbon atoms. The ionomer is neutralized to a level of about 5% to about 90%, based on the total carboxylic acid content of the acid copolymer, and further comprises at least one cation. Further provided are articles comprising the light-weight ballistic resistant safety glazing.
