Patent ID: 7391208

Claim:
A position sensor for sensing an angular position, comprising: at least two magnetic conductive structures, including a first magnetic conductive structure and a second magnetic conductive structure, said first magnetic conductive structure being substantially arcuately parallel with said second magnetic conductive structure; at least two magnets, including a first magnet and a second magnet, said first magnet being magnetically coupled with said first magnetic conductive structure and with said second magnetic conductive structure, said second magnet being magnetically coupled with both said first magnetic conductive structure and said second magnetic conductive structure; a magnetic flux responsive device constrained to travel a path that is partially located between said first magnetic conductive structure and said second magnetic conductive structure, said path extending beyond at least one of said at least two magnets; an arcuate magnet positioned concentrically with said path; an other magnetic flux responsive device that travels an other path, said other path being proximate to said arcuate magnet, said other magnetic flux responsive device is biased by said arcuate magnet when said magnetic flux responsive device is not between said first magnetic conductive structure and said second magnetic conductive structure, said other magnetic flux responsive device is additionally biased by said arcuate magnet along a portion of said other path when said magnetic flux responsive device is between said first magnetic conductive structure and said second magnetic conductive structure, a signal from said magnetic responsive device and a signal from said other magnetic responsive device are combined.
