Abstract
An angular rotation sensor system constituted of: a first target with a member radially extending from, and rotating about a longitudinal axis of the first target; a second target with a member radially extending from, and rotating about a longitudinal axis of the second target; a first receive coil comprising a plurality of loops laid out such that adjacent loops exhibit opposing magnetic polarities responsive to a radio frequency current injected into the transmit coil; a second receive coil comprising a plurality of loops laid out such that adjacent loops exhibit opposing magnetic polarities responsive to a radio frequency current injected into the transmit coil; and an output coupled to each of the first and second receive coils, wherein each of the members is shaped and sized to generally match a shape and size of a pair of loops.
