Abstract:
A photochromic device is provided which allows the user to leave the device in a high transmissive state even when exposed to a source of radiation and to control the degree of darkening achieved while exposed to the source of radiation.
Abstract:
Electrochromic coating solutions are prepared by reacting a transition metal with a mixture of hydrogen peroxide and an organic acid. The resulting transition metal-peroxy acid product is esterified by reacting with lower carbon alcohols to produce a peroxyester-transition metal derivative. This derivative in solution in lower carbon alcohols provides a working solution into which a substrate having a conductive surface is preferably dipped and removed at a rate sufficient to give a coating of a desired thickness over the conductive surface. Spray or spin coating can be used to apply the coating to the conductive surface of the substrate. The coating is then dried and is externally fired in an oven to complete the necessary reactions to yield an electrochromic oxide coating having exceptional electrochromic properties.
Abstract:
Briefly, an intelligent label is associated with a good, and includes one or more permanent and irreversible electrochromic indicators that are used to report the condition of that good at selected points in the movement or usage of that good. These electrochromic indicators provide immediate visual information regarding the status of the good without need to interrogate or communicate with the electronics or processor on the intelligent label. In this way, anyone in the shipping or use chain for the good, including the end user consumer, can quickly understand whether the product is meeting shipping and quality standards. If a product fails to meet shipping or quality standards, the particular point where the product failed can be quickly and easily identified, and information can be used to assure the consumer remains safe, while providing essential information for improving the shipping process. It will be understood that the label may take many forms, such as a tag attached to the good, integrated into the packaging for the good, integrated into the good itself, or may even be an information area on a prepaid card for example. The label may also include, for example, print information regarding the good, usage or shipping rules, or address and coded information.
Abstract:
This invention focuses on electrooptic devices and in particular on electrochromic (EC) devices with many aspects directed towards automotive EC mirrors. This invention improves the visual impact of such devices by employing modifications to the materials and layers so that their refractive index can be changed and/or matched to get this improvement. In addition this also discloses use of in-molded electronic components to reduce the assembly cost of these devices and improve their reliability. Displays can be incorporated in EC mirrors while having reflective coatings on the fourth surface.

Abstract:
The invention relates to use of masterbatches containing high concentrations of antimicrobial materials such as copper salts, particularly copper iodide. These masterbatch compositions are added to other materials which are used to form various articles of manufacture with antimicrobial properties. The copper salts may be incorporated in the masterbatches as surface functionalized particles or the salts may be incorporated into porous particles prior to the formation of masterbatches.
Abstract:
The invention relates to compositions, methods and preparation of such compositions to protect metals from corrosion, especially acid corrosion. The compositions of this invention may be added to acids to protect metals from their corrosive influence, particularly at elevated temperatures. These compositions are of particular utility in the oil and gas (petroleum) industry. Also disclosed are “corrosion inhibition intensifiers” to enhance the corrosion inhibition properties of other corrosion inhibitors. Formulations which control ferric ions in acidic solutions are also disclosed. These may be combined with inhibited acids and some compositions provide both corrosion inhibition and ferric ion control.
Abstract:
Compositions having antimicrobial activity contain surface functionalized particles comprising an inorganic copper salt which has low water solubility. These types of inorganic salts may also be introduced in porous particles to yield antimicrobial compositions. The compositions may optionally comprise additional antimicrobial agents, salts with high water solubility, organic acids, salts of organic acids and their esters. The compositions may be added to various fluids used in the petroleum extraction industry, or used as coatings on components used in this industry. These antimicrobial materials may be used for reducing both anaerobic and aerobic bacteria and are also useful for reducing corrosion of ferrous components caused by anaerobic bacteria. Although such compositions may be used for any antimicrobial application, and some of the other important uses of these compositions are in wound care, personal care and waste processing.
Abstract:
A safer, low-cost practical method of dissolving beryllium or a beryllium compound including beryllium oxide in a sample is disclosed. This method discloses use of acidic solutions under mild heating conditions to dissolve beryllium and its compounds. These solutions may then be used to quantitatively analyze for beryllium so as to be able to determine the amount of beryllium in the sample. These solutions may also be combined with fluorescent dye indicating solutions to determine beryllium by fluorescence. A preferred fluorescent dye indicating solution contains a dye (10-hydroxybenzo[h]quinoline-7-sulfonate) which specifically binds with beryllium under basic conditions.

This invention focuses on automotive electrochromic (EC) mirrors. There are several ways to improve the attribute of this product and also use superior processing methods. This invention improves on busbars which are used to power these devices. This discloses novel busbar designs, materials and busbar deposition methods. This invention also addresses the composition of transparent conductor coatings which can be used in an advantageous configuration for third surface mirrors, and corrosion resistant reflective coating compositions for EC mirrors. Processing methods to deposit coatings for third surface mirrors are also disclosed. Insignias may also be incorporated in EC mirrors by using conductive materials deposited on the second surface of an EC mirror configuration that is formed by two substrates.
