  • Patent number: 11444476
    Abstract: A lightning strike probability-based coordinated power control method for an energy storage system and a load adjusts output power of an energy storage system and a regulatable load based on a real-time predicted lightning strike probability.

    Abstract: This application relates to apparatus and methods for mapping identifiers to customer data over temporal intervals. Various applications may then operate on the mapped customer data to generate output data, such as digital item advertisements. In some examples, a computing device receives a first identifier of a first type, and a plurality of second identifiers of a second type. The computing device obtains customer data, such as sales and browsing data, associated with each of the second identifiers, and generates a confidence score for each of the second identifiers based on the corresponding customer data. Further, the computing device generates mapping data that maps the first identifier to one of the plurality of second identifiers based on the confidence scores. In some examples, the computing device determines the mapping data based on temporal intervals associated with the first identifier and each of the plurality of second identifiers.
