摘要： A method for detection of passing magnetic articles which includes an initial step of sensing an ambient magnetic field and generating a voltage, Vsig, proportional to the magnetic field. A threshold voltage is generated as a percentage of the peak-to-peak voltage of Vsig. The method further includes the step of generating a detector output voltage that becomes one binary level when Vsig rises to exceed the threshold voltage and another binary level when Vsig falls to below the threshold voltage. The threshold voltage is updated to track the positive and negative peaks of the Vsig voltage and is further updated by a predetermined amount upon each transition of the Vout voltage.

摘要： A magnetic-field-to-voltage transducer includes a Hall element and a digitally gain-controlled Hall-voltage amplifier that produces an analog voltage Vsig having excursions of one polarity corresponding to the passing of magnetic articles. Vsig is applied to the input of a signal-manipulating circuit that generates a proximity- detector binary output voltage, Vout, having transitions of one direction each time a predetermined point is reached in Vsig. A digitally gain-controlled gain amplifier is connected to the Hall element. A comparator circuit generates a binary signal Vbig (or V.sub.toobig) that changes from one to another binary level each time that Vsig exceeds a DC target voltage, V.sub.TG. The AGC circuit senses and counts gain counter excursions of one polarity in Vsig, and produces a binary count output signal at the input of the gain amplifier at each of the counted excursions in Vsig, incrementally changing the transducer gain in the direction to bring the peaks in Vsig to just below the target value T.sub.TG. This AGC feature prevents saturating the amplifier and quickly renders a Vsig of essentially constant amplitude so that either the peak excursion values or predetermined threshold levels in Vsig, at which transitions in the proximity detector output voltage Vout are caused to occur, provide greater accuracy and stability in the correlation between detection-approach and -withdrawal distances and transitions in Vout.

The method also includes communicating at least one of the plurality of potential categories into which at least one of the one or more characteristic values was categorized. A magnetic field senor implements the above method.

摘要： An angle sensor to provide sensor-to-magnet misalignment detection and correction capability in rotation angle measurement applications is presented. The angle sensor has magnetic field sensing elements to sense magnetic field associated with a rotating magnet. The angle sensor includes circuitry to generate signals based on the sensing by the sensing elements. The signals provide information that can be combined according to an error function to provide misalignment detection. The angle sensor can be used with or can be incorporated in an angle measurement device that employs a processing unit to produce a rotation angle value. In one embodiment, the processing unit is configured to implement the error function and correct the angle value for detected misalignment. In another embodiment, the error function is performed by a programming device and detected misalignment is corrected through mechanical adjustment of sensor-to-magnet position.
