    Abstract: A sensor assembly includes a magnetic track having a plurality of magnetic poles separated by a plurality of pole junctions. The sensor assembly also includes a first magnetic sensor disposed proximate a high-resolution portion of the magnetic track and a second magnetic sensor disposed proximate a reference portion of the magnetic track. The second magnetic sensor spans adjacent pole junctions in the magnetic track. Each of the adjacent pole junctions includes a high-resolution segment corresponding with the high-resolution portion of the magnetic track and a reference segment corresponding with the reference portion of the magnetic track. The reference segment of each pole junction is one of offset and aligned with the corresponding high-resolution segment in each pole junction.

    Abstract: A system and method for determining a position and or speed of a rotating shaft includes a target wheel for securement to a rotatable shaft, the target wheel including a plurality of North/South pole pairs, each pole of each North/South pole pairs being essentially the same size; and a sensor assembly. The sensor assembly includes a first magnetic sensor array for sensing the pole pairs to provide a cosine signal and a sine signal and a second magnetic sensor array for sensing the pole pairs to provide a cosine signal and a sine signal, wherein the second magnetic sensor array is disposed transverse to the first magnetic sensor array. An electronic processor is configured to receive inputs from the first magnetic sensor array and the second magnetic sensor array, and to determine a position and/or speed of the shaft.

    Abstract: A method and apparatus for sensing magnetic field strength with a pair of Hall effect sensors includes sampling a sensed voltage for the Hall effect sensors during a first phase and combining the sensed voltage. During a second phase, obtaining sensed voltages for the Hall effect sensors and combining the sensed voltages. The sensed voltages from the first phase and the second phase are combined to obtain a summed voltage and remove the Hall effect sensor and amplifier offset error value. In one arrangement, the summed voltage corresponds to the sensed Hall voltage of the first Hall effect sensor added to the Hall voltage of the second Hall effect sensor. In another arrangement, the summed voltage corresponds to the sensed Hall voltage of the first Hall effect sensor subtracted by the sensed Hall voltage of the second Hall effect sensor. Changes in the summed voltage with respect to a reference voltage are counted to determine the speed of a rotating shaft having magnets or a similar arrangement.

    Abstract: A system for determining an absolute position of a device includes a high resolution track (14), a sensor and processing unit (22) associated with the high resolution track (14), a reference track (18) having a plurality of pole pairs arranged to define a single-track Gray code segment, and an array of Hall effect sensors (26) associated with the reference track to output a reference signal to the sensor and processing unit indicative of the coarse absolute position of the device over the single-track Gray code segment. The sensor and processing unit (22) combines the reference signal with the position of the device over the high resolution track to determine an initial, fine absolute position of the device. An up/down hardware counter (34) increments the initial fine absolute position using a signal generated from the high resolution track, and without any further software- based processing, to maintain and continuously update the fine absolute position of the device.
