  • Publication number: 20200407037
    Abstract: A dust cover for an aerospace window that comprises dust cover having an exterior substrate and an interior substrate in a spaced apart relationship with a substantially transparent coupling agent therebetween. The dust cover is disposed in a spaced apart relationship from an electro-optic element, defining a gap therebetween. The gap 30 mm or less, 25 mm, 20 mm, 15 mm, 10 mm, 8 mm, 7 mm, 6 mm, 5 mm, 4 mm, 3.5 mm, and/or 3 mm. The exterior substrate, the coupling agent, and the interior substrate are comprised of a combination of materials, such that the combination is substantially transparent and operable to resist breaking and maintain sufficient rigidity to prevent the electro-optic from breaking, when a force of 680 N is applied to an interior surface of the interior substrate in the direction of the electro-optic element.

  • Publication number: 20190339580
    Abstract: A transparent photovoltaic (TPV) integrated directly into the structure of an electrochromic (EC) device is beneficial in that it can eliminate at least one substrate and provide more uniform coloring. Integration of a transparent photovoltaic with an electrochromic device may also reduce or eliminate the need for an electrical bus on a substrate. In some embodiments, positioning the TPV internally with the EC cell may eliminate the need for additional substrate layers or a conductive layer on one side of the TPV cell. Integrating a PV cell into the EC device can additionally reduce the need for external wiring and an external power supply. Alternatively, the TPV can assist in charging a battery where the battery can be used to power the EC device when there is no sunlight available.

  • Patent number: 10467050
    Abstract: A Workflow Engine and an associated User Interface configured to substantially automate aspects of the creation and management of a Workflow comprising a plurality of related jobs. The Workflow Engine employs a declarative web interface design with reduced or no required coding, reuses jobs for automating the same task in different contexts, employs declarative sequencing of jobs with reduced or no required coding, and uses job templating to increase or ensure consistent configurations across multiple job invocations. Users select and modify jobs from a library of existing jobs, and create new jobs as needed. The Workflow executes the jobs according to a Flow Script and communicates output data between jobs to satisfy dependencies. The User Interface allows users to monitor and manage the jobs and the Workflow, including creating an interactive visual presentation of job dependencies.
