Abstract: A first magnetic encoder assembly includes a magnetic encoder ring. The magnetic encoder ring has a circumferential surface and a magnetic field. The magnetic field has a direction which substantially continuously varies in angle as one travels along the circumferential surface. A second magnetic encoder assembly includes a substantially-linearly-extending magnetic encoder strip. The magnetic encoder strip has a magnetic working length and a magnetic field. The magnetic field has a direction which substantially continuously varies in angle as one travels along the magnetic working length.

Abstract: A system for measuring relative wheel velocity including an unsprung mass having a wheel connected thereto, a sprung mass pivotally connected to the unsprung mass by a pivot point and an angular rate sensor mounted on the sprung mass (or the unsprung mass) generally adjacent to the pivot point.
