Abstract
Identifying position of a first rotating shaft may comprise a first position detection system and a second position detection system. A controller may be coupled to a first sensor and a second sensor and may identify the position of the first shaft using the identified shaft position from either the first detection system or the second detection system, whichever is identified faster. The first shaft may have a first wheel disposed thereon with targets and one or more gaps disposed about the first wheel. A second shaft may have a second wheel disposed thereon with targets and one or more gaps disposed thereon. The second wheel is in a fixed relationship relative to the first wheel. The first detection system may use data simultaneously from the first sensor and the second sensor to eliminate targets to determine position. The second detection system uses data only from the first sensor.
