  • Patent number: 10707107
    Abstract: Adaptive alignment methods and systems are disclosed. An adaptive alignment system may include a scanner configured to align a wafer and an analyzer in communication with the scanner. The analyzer may be configured to: recognize at least one defined analysis area; determine whether any perturbations exist within the analysis area; and in response to at least one perturbation determined to be within the analysis area, invoke a fall back alignment strategy or report the at least one perturbation to the scanner.
    Type: Grant

  • Patent number: 10692227
    Abstract: A system for determining a sample map for alignment measurements includes a metrology tool and a controller. The controller defines a full sampling map including a plurality of measurement locations. The controller directs the metrology tool to measure alignment at each measurement location of the full sampling map for a plurality of samples to generate a reference alignment dataset, generates candidate sampling maps, each being a subset of the full sampling map. The controller may further estimate alignment as a function of location based on the two or more candidate sampling maps at each measurement location of the full sampling map, and determine a working sampling map by comparing the estimated alignment to the reference alignment dataset and selecting the candidate sampling map having a smallest number of alignment estimates exceeding a selected tolerance.

  • Patent number: 9384510
    Abstract: Methods and apparatus are disclosed for providing a roof guide, the method including: receiving, via an application on the mobile device of a user, a query related to one or more of a type of a roof and a type of damage to the roof; providing the query to a central server; retrieving, from the central server, at least one first roof image responsive to the query; receiving, via the application on the mobile device of the user, user input of a second roof image of a portion of the roof; and displaying, via the application on the mobile device of the user, the at least one first roof image and the second roof image.

  • Publication number: 20150356687
    Abstract: Methods and apparatus are disclosed for determining a subrogation score for a potential subrogation claim. The systems and methods described herein provide a user, such as a claims adjuster, with the tools to retrieve and communicate information related to one or more products likely to have caused a property loss. The systems and methods may further determine a subrogation score indicative of subrogation opportunity for a potential subrogation claim relative to the one or more products. The subrogation score may be based on information in at least one database. The subrogation score may be provided to the user such as an insurance carrier. The user may then decide whether to proceed with further investigative analyses (e.g., component testing of the one or more products) pursuant to a potential subrogation claim. Additional systems and methods disclosed herein facilitate the insurance carrier's submission of the one or more products for component testing.
