Abstract
A variable inductor direction sensor may include a rotatable body having a first circumferential tooth array and a stationary body having a second circumferential tooth array. The second circumferential tooth array may be concentric with the first circumferential tooth array. The rotatable body may be disposed relative to the stationary body such that one of the first circumferential tooth array and the second circumferential tooth array circumscribes the other of the first circumferential tooth array and the second circumferential tooth array. Further, at least one of the first circumferential tooth array and the second circumferential tooth array has a non-uniform circumferential geometry.
