  • Publication number: 20230375627
    Abstract: Sensors and methods for determining the state of charge of a battery are described. The state of charge is determined in some instances by applying a current perturbation having a frequency to the battery terminals, monitoring the response signal, and determining the phase of the response signal. The phase may be correlated to the state of charge of the battery, so that once the phase is determined, a determination of the state of charge of the battery may be made. In some situations, the state of charge may be used to determine the operating condition of a load connected to the battery. In some embodiments, the state of charge may be used to determine whether the battery is defective.

    Abstract: A method for training a model comprises obtaining a set of labeled training samples each associated with a given label. For each labeled training sample, the method includes generating a pseudo label and estimating a weight of the labeled training sample indicative of an accuracy of the given label. The method also includes determining whether the weight of the labeled training sample satisfies a weight threshold. When the weight of the labeled training sample satisfies the weight threshold, the method includes adding the labeled training sample to a set of cleanly labeled training samples. Otherwise, the method includes adding the labeled training sample to a set of mislabeled training samples. The method includes training the model with the set of cleanly labeled training samples using corresponding given labels and the set of mislabeled training samples using corresponding pseudo labels.

  • Publication number: 20230342528
    Abstract: Techniques for implementing a mixed signal feedback design for verification that reduce production and verification time by enabling piecemeal verification of components of a circuit design selectively, accurately, and exhaustively before a final, overall circuit design is completed are disclosed. Circuit nodes in an emulation model are selected and mixed signal feedback is provided to the nodes in response to signals detected at the nodes such that behavior of unavailable or unverified components to be located at the nodes can be simulated. Mixed signal feedback can be provided to the node to enable verification of the emulation model without having to wait for the unverified or unavailable components to be provided or verified. A request for manufacture may be generated including aspects of the emulation model to enable verification of a fabricated circuit in a similar or identical manner to those used to verify the emulation model.

  • Publication number: 20230316125
    Abstract: Determining a class-specific predictor indicator importance can include generating, using machine learning, a prediction model having a tree structure including nodes, class label subgroups, and class-specific predictor indicators. A class-specific predictor indicator importance can be generated for a selected class-specific predictor indicator by merging a term predictor indicator frequency and a purity predictor indicator frequency at each instance of the selected class-specific predictor indicator within one or more nodes of the tree structure. A representation of the tree structure displayed in a graphical user interface can depict each path between a root node of the tree structure and a leaf node mapped to the selected class label subgroup having a node containing an instance of the selected class-specific predictor indicator in a manner that contrasts with other paths between the root node and other leaf nodes of the tree structure.
