SYSTEM FOR DETERMINING QUALITY OF A ROTATING POSITION SENSOR SYSTEM
First Claim
Patent Images
1. A method for assessing quality of a magnetic sensor profile, comprising:
- during rotation of an object sensed by a position sensor, storing data associated with a quality of a magnetic sensor profile within the position sensor, and outputting position data via a pin of the position sensor; and
during non-rotation of the object, outputting at least a portion of the data associated with the quality of the magnetic sensor profile via the pin.

Abstract
A method for improving a position sensing system which measures a rotating object is presented. In one embodiment, the method outputs the position of the rotating object while the object is rotating, and the method follows an external command on the sensor output line when the object is not rotating to output information other than the position information.

9. A system for determining a quality of a magnetic sensor profile, comprising:
a sensor configured to sense a position of an object, the sensor configured with an output that provides position information of the object to a single output pin while the object is rotating, and the sensor configured to output data associated with a quality of a magnetic sensor profile other than the position information of the object via the single output pin when the object is not rotating. - View Dependent Claims (10, 11, 12, 13, 14, 15)

16. A system for determining a position of a rotating object, comprising:
-
a sensor with a first controller having instructions for sensing a position of an object, the first controller having further instructions for outputting position information of the object via a single output pin while the object is rotating, and the first controller having further instructions for outputting data associated with a quality of a magnetic sensor profile other than the position information of the object via the single output pin when the object is not rotating; and a second controller, the second controller external of the sensor and including instructions for adjusting a state of the single output pin after the object stops rotating. - View Dependent Claims (17, 18, 19, 20)
