Abstract: Systems, methods, and devices are provided for producing and using a low-value inductor which is stable at high frequencies, the inductor including a plurality of radial spokes extending between two concentric rings. The inductance of the inductor is controlled by the number and dimensions of the plurality of spokes, as well as the materials of the inductor. In some cases, the inductor is used as a low value inductance standard for directly measuring a low value electrical inductance.

Abstract: A system including: a computer system configured to: access geographical information system (GIS) data, including land-parcel data representing land-parcel coordinates that define a plurality of land parcels, and publicly accessible destination data representing coordinates of publicly accessible destinations, and/or publicly accessible region data representing one or more regions with associated features, and process the GIS data to generate processed GIS data representing attributes of each land parcel associated with: distances between each land parcel and the publicly accessible destinations; and/or features of the regions that overlap with the land-parcel coordinates; and at least one server configured to: receive request data representing query criteria for selecting ones of the land parcels; filter the processed GIS data to select ones of the land parcels with distances and/or features matching the query criteria; and generate response data representing the selected ones of the land parcels.
