  • Publication number: 20200044298
    Abstract: This disclosure relates to a battery for an electrified vehicle and a corresponding method. In particular, the battery and method accommodate for variable cell thickness. An example method of this disclosure includes inserting a separator between a first battery cell and a second battery cell. The separator has a thickness based on a thickness of the first battery cell and the second battery cell. This disclosure has a number of benefits. Among them, the method may be used to provide a battery array with a desired overall length despite differences in individual cell thickness. In turn, this leads to improved battery performance and lifespan.

  • Publication number: 20190302031
    Abstract: Methods and systems for selecting a mode for inspection of a specimen are provided. One method includes determining how separable defects of interest (DOIs) and nuisances detected on a specimen are in one or more modes of an inspection subsystem. The separability of the modes for the Dais and nuisances is used to select a subset of the modes for inspection of other specimens of the same type. Other characteristics of the performance of the modes may be used in combination with the separability to select the modes. The subset of modes selected based on the separability may also be an initial subset of modes for which additional analysis is performed to determine the final subset of the modes.

  • Patent number: 10267748
    Abstract: Methods and systems for training an inspection-related algorithm are provided. One system includes one or more computer subsystems configured for performing an initial training of an inspection-related algorithm with a labeled set of defects thereby generating an initial version of the inspection-related algorithm and applying the initial version of the inspection-related algorithm to an unlabeled set of defects. The computer subsystem(s) are also configured for altering the labeled set of defects based on results of the applying. The computer subsystem(s) may then iteratively re-train the inspection-related algorithm and alter the labeled set of defects until one or more differences between results produced by a most recent version and a previous version of the algorithm meet one or more criteria. When the one or more differences meet the one or more criteria, the most recent version of the inspection-related algorithm is outputted as the trained algorithm.
