  • Patent number: 11891327
    Abstract: 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. In certain embodiments, the device includes a counter electrode having an anodically coloring electrochromic material in combination with an additive.

    Abstract: Various embodiments include components (e.g., a processor in a vehicle advanced driver assistance system) configured to identify subsystems that require testing in order to verify their compliance with a safety requirement. The components may determine whether verification of compliance requires that the subsystems be tested at PON, at POFF, during runtime or a combination thereof, dynamically determine the achievable parallelism for testing the identified subsystems, dynamically determine coverage level requirements for performing or executing built in self tests (BISTs) on each identified subsystem, and perform or execute the BISTs on the subsystems at the determined level of parallel and at the determined coverage level.

  • Patent number: 11440838
    Abstract: 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. In certain embodiments, the device includes a counter electrode having an anodically coloring electrochromic material in combination with an additive.
