Abstract: Methods, systems, and devices are described that support extensible data mapping. A data mapping server may receive an indication of a source schema for a data source and may receive a user input indicating creation of a custom data object to handle the source schema. The server may create the custom data object based on the user input. The data mapping server may automatically map one or more data fields for a source data object (e.g., based on the source schema) to one or more custom data fields for the custom data object (e.g., based on a custom schema). The server may import a set of data records stored at the data source and may store the data records in a database system according to the custom schema based on the data mapping. The stored custom data objects may be used for segmentation, activation, analysis, or some combination thereof.

Abstract: A central shaft is oriented in a position that is normal to the surface of the ground and normal to a direction of fluid flow. The central shaft has a plurality of blades emanating from the central shaft, wherein each one of the plurality of blades has an outside edge and an inside edge, the inside edge being attached directly to an outside surface of the central shaft. The outside edge of the blade extends upward curving around the central shaft and the inside edge of the blade extends upward curving around the central shaft. The turn rate of the inside edge of the blades about the central shaft is less than the turn rate of the outside edge of the blades about the central shaft.

Abstract: The invention discloses at least one blade extending away from a beginning point and longitudinally along a central axis and approximating the shape of a spiral about said central axis. The blade comprises a beginning point disposed a first lateral distance away from the central axis and a terminating point disposed a second lateral distance away from the central axis, the second distance being greater than the first distance.
