Abstract:
Pyroelectric detector systems may be used in vehicles for security applications, such as intrusion detection and anti-theft alarms. The pyroelectric detectors are small in size, highly reliable and consume very low power. They can be physically and electrically integrated with other vehicle components, including rear-view mirror assemblies in automobiles, without incurring additional installation costs. They can also be easily integrated into aircraft cockpits.

A chromogenic window panel assembly, and a chromogenic skylight each includes an outer panel and a chromogenic member having an optical property which varies according to an applied signal. A chromogenic light pipe includes a light harvesting member and a chromogenic member having an optical property which varies according to an applied signal. A chromogenic vehicle sunroof, a chromogenic aircraft window assembly, and a chromogenic window assembly each includes a panel having a particular panel contour corresponding to a surface contour and a chromogenic panel having an optical property which varies according to an applied signal. A chromogenic block includes two panels and a chromogenic panel having an optical property which varies according to an applied signal.
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:
The present invention relates to electrochromic polymeric solid films, manufacturing electrochromic devices using such solid films and processes for making such solid films and devices. The electrochromic polymeric solid films of the present invention exhibit beneficial properties and characteristics, especially when compared to known electrochromic media. The electrochromic polymeric solid films are transformed in situ from a low viscosity electrochromic monomer composition by exposure to electromagnetic radiation, and in so doing minimum shrinkage occurs. The electrochromic polymeric solid films of the present invention also perform well under prolonged coloration, outdoor weathering and all-climate exposure, and provide an inherent safety aspect not known to electrochromic media heretofore.
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 preferable 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:
Electrochromic mirrors are protected against environmental and mechanical damage by an encapsulant system comprising a shatterproofing backing and a hermetic seal. The shatterproofing backing entirely covers the surfaces of the electrochromic cell elements and is itself entirely covered by the hermetic seal.
Abstract:
This invention discloses how EC devices can be fabricated as tags or labels; and further the materials used, device structures and how these can be processed by printing technologies. In addition, systems using displays of such EC devices and their integration with other components are described for forming labels and tags, etc, that may be actuated wirelessly or powered with low voltage and low capacity batteries.
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.
