Abstract: This invention focuses on electrooptic devices and in particular on electrochromic devices with many aspects directed towards automotive EC mirrors. There are several ways to improve these products and their processing using this invention and some of the prominent ones are outlined below. This invention improves on the devices by disclosing new compositions for electrodes and methods of depositing them. It also addresses novel ways to provide busbars to power these devices in order to improve their performance. The device processing attributes and performance are also improved by adhesive compositions and solid electrolytes disclosed herein. In addition sensors are also disclosed which are novel for use in electrochromic mirrors. The invention also discloses how the electrolytes comprising ionic liquids have no adverse effect on attributes of commercial EC mirrors and often result in improved performance and/or feature enhancements.

Abstract: This invention discloses methods to dispense adhesives for fabricating electrooptic devices. In addition the invention also discloses on how the cavities of these electrooptic devices may be filled using detachable tabs. The Electrooptic devices of this invention may comprise liquid or solid electrolytes.

Abstract: New and useful sign structure is provided, that is designed to be (i) efficient and cost effective to produce, (ii) easily and efficiently assembled, in order to change the message conveyed by the sign structure, and (iii) effectively rotated by the air movement in the vicinity of the sign structure. The sign structure comprises a support rod, and a sign comprising a specially formed panel that is rotatable on the support rod. A bearing surface is integrally connected with the panel (preferably formed in one piece with the panel) and extends along a predetermined portion of the panel. The bearing surface is configured to slide over the support rod and to rotate on the support rod, so that the panel is rotatable about the support rod. In a preferred form, the panel comprises a synthetic material having a corrugated configuration with at least one corrugation forming the bearing surface for the panel.

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.

Abstract: Provided by this invention are two-part liquid polysulfide compositions which utilize stable and effective manganese dioxide or like curing agents which provide reasonable working times and gel times typically a maximum of 90 minutes and desirably rapid cure rates. Also, provided are stable and effective manganese curing compositions suitable for use as an element of such two-part liquid polysulfide compositions.

Abstract: Provided by this invention are thixotropic polymer compositions, which are useful upon curing to make tough coatings, sealants, adhesive bonds and molds. The compositions can be supplied to the site of use as two low viscosity liquid parts, which when mixed provide rapid onset of thixotropy. One or more polyisocyanates and one or more aromatic diamines are used in making the compositions. Processes for making coatings, sealants, adhesive bonds and molds by use of the compositions are also provided.
