Abstract: Methods and apparatuses to obtain increased performance and differentiation for an inductive position sensor through non-disruptive placement of multiloop coil interconnects are disclosed. In a particular embodiment, a sense element includes at least one transmit coil; a first receive coil that includes a first plurality of arrayed loops, wherein two or more of the first plurality of arrayed loops are phase blended; and a first plurality of interconnects, each of the first plurality of interconnects connecting two of the first plurality of arrayed loops, wherein the first plurality of interconnects is disposed outside of a sensing area of the sense element.

Abstract: Methods and apparatuses to obtain increased performance and differentiation for an inductive position sensor through improvements to the sense element and target design are disclosed. In a particular embodiment, a sense element includes a transmit coil, a first receive coil that includes a first plurality of arrayed loops, wherein two or more of the first plurality of arrayed loops are at least one of phase blended and amplitude arrayed, and a second receive coil that includes a second plurality of arrayed loops, wherein two or more of the second plurality of arrayed loops are at least one of phase blended and amplitude arrayed, and wherein the first receive coil and the second receive coil are phase shifted. The sense element coils are arrayed in several geometries and layouts, and the coil and target geometry are manipulated to compensate for inherent errors in the fundamental design of an inductive position sensor.
