Claim Text:
1. A metrology assembly comprising: a substrate having a top side, an underside, and a slot; one or more U-shaped electrical conductors configured to conduct electric current, each U-shaped electrical conductor comprising: a top portion having a length and a width; and two substantially parallel leg portions that are connected together at one end by the top portion to form a U-shape such that the length of the top portion spans at least a portion of a distance between the two substantially parallel leg portions, wherein each U-shaped electrical conductor is coupled to the substrate by the top portion being disposed through the slot in the substrate, a length of the slot spanning at least the length of the top portion, and a width of the slot spanning at least the width of the top portion, wherein the top portion is disposed on the top side of the substrate, and the two substantially parallel leg portions are disposed on the underside of the substrate; an additional electrical conductor having an aperture through a width of the additional electrical conductor, the additional electrical conductor being coupled to the substrate by the substrate being disposed through the aperture; and at least two Hall effect devices associated with an electrical conductor of at least one of the additional electrical conductor or the one or more U-shaped electrical conductors, the at least two Hall effect devices being coupled to the substrate and positioned at opposing sides of the electrical conductor, each of the at least two Hall effect devices configured to detect a magnetic field created by the electric current conducted in the electrical conductor and to generate an output.
