Abstract: Techniques are disclosed for generating a search index for a hierarchical data set so that a search query of the hierarchical data may return results without searching or analyzing the hierarchical data set itself. The techniques generate a flattened index that includes selected indexed attributes and additional attributes to be displayed with the indexed attributes. The techniques also generate a hierarchy representation of the hierarchical data. Using these generated data structures, query results may be returned without directly traversing the hierarchical data itself while also providing data and hierarchical context for the query results by overlaying the query results with nodes of the hierarchical representation or otherwise concurrently displaying the query results with nodes of the hierarchical representation.

Abstract: A dual-wheel differential system includes an in inner hub, an outer hub, and a differential assembly mechanically coupled between the inner hub and the outer hub to allow the inner hub and the outer hub to rotate at different angular speeds. A user-actuatable locking system is configured to mechanically lock the inner hub to the outer hub. The user-actuatable locking system may include at least one axially-translating or radially-translating locking pin configured to engage at least one of the inner hub and the outer hub. The locking system may be pneumatically, hydraulically, or electromechanically actuated.

Abstract: The subject invention provides a wheel assembly (20) having a spindle (26) for attachment to a vehicle along a rotational axis (R). An electric motor (22) is disposed radially about the spindle (26) and includes a stationary stator (34) and a rotor (36) rotatable about the rotational axis (R) relative to the stator (34). A rotor support (40) is disposed about the spindle (26) and includes a collar (42) rotatably supported by at least one rotor support bearing (46) on the spindle (26). The rotor support (40) includes a flange (44) disposed within a predetermined axial distance (D) and extending radially outward from the collar (42) to support the rotor (36). A planetary gear system (62) interconnects the rotor support (40) and a wheel drive (52) for reducing rotational speed of the rotor (36) and increasing the torque of the wheel assembly (20).
