Abstract: Methods for improving data accuracy in a positioning system database using aerial imagery are provided. In one aspect, a method includes obtaining a two-dimensional image providing an aerial perspective of a building including a business, and receiving from a user a path identifier indicative of a virtual roadway proximal to the building, a first identifier in the first two-dimensional image of a first edge, second edge, and entrance of the business relative to the building. The method also includes determining first, second, and third latitude and longitude pairings on a map for the first identifier, second identifier, and third identifier, respectively, and providing, for display in the image, an identification of the first edge, second edge, and entrance of the business. Systems and machine-readable media are also provided.

Abstract: Methods for improving data accuracy in a positioning system database are provided. In one aspect, a method includes obtaining an image of a building including a business, and receiving from a user a first identifier in the image of a first edge of the business. The first identifier is associated with a first axis heading in the direction of the first edge of the business. The method also includes receiving from the user a second identifier of a second edge of the business, the second identifier associated with a second axis, receiving from the user a third identifier of an entrance to the business, the third identifier associated with a third axis, and identifying first, second, and third points on the first, second, and third axes, respectively, to identify the first edge, the second edge, and the entrance of the business on the map. Systems and machine-readable media are provided.

Abstract: The present invention provides an improved magnetic winding and method of calculating desired winding parameters (winding layer thickness, number of winding layers and number of turns per winding layer) for a winding in a magnetic component. The invention may be applied to general boundary conditions in a magnetic winding or component and considers relative phase displacement for sinusoidal and nonsinusoidal winding currents. Ratios of magnetic surface field intensities at corresponding inner and outer boundaries of one or more winding layer(s) are calculated, and considered with relative phase displacement to select magnetic winding configurations having desired or optimal power dissipation. In certain aspects, a normalized loss function f(H,R,B,?) is utilized to determine a preferred construction among a plurality of iteratively generated selections.
