Method and system associated with a sensing roll and a mating roll for collecting data including first and second sensor arrays

A method associated with a sensing roll and a mating roll comprising:

• providing the sensing roll and the mating roll;
• generating a first respective sensor signal from each sensor of a first sensor array located at axially spaced-apart locations of the sensing roll, wherein each first respective sensor signal is generated when each sensor enters a region of a nip between the sensing roll and the mating roll during each rotation of the sensing roll;
• generating a second respective sensor signal from each sensor of a second sensor array located at axially spaced-apart locations of the mating roll, wherein each second respective sensor signal is generated when each sensor enters a region of a nip between the sensing roll and the mating roll during each rotation of the mating roll,
• identifying a periodically occurring first time reference associated with each rotation of the mating roll;
• identifying a periodically occurring second time reference associated with each rotation of the sensing roll;
• receiving a received sensor signal, the received sensor signal comprising one of the first respective sensor signal and the second respective sensor signal and, upon receiving the received sensor signal:
• determining a particular one of the plurality of sensors which generated the received sensor signal,
• when the particular one sensor is from the first sensor array, then based upon a most-recent-identified first time reference, determining a detected tracking segment based on which one of a plurality of first tracking segments associated with the mating roll enters the region of the nip substantially concurrently with the particular one sensor from the first array,
• when the particular one sensor is from the second sensor array, then based upon a most-recent-identified second time reference, determining a detected tracking segment based on which one of a plurality of second tracking segments associated with the sensing roll enters the region of the nip substantially concurrently with the particular one sensor from the second array;
• and
• storing the received sensor signal to associate the received sensor signal with the detected tracking segment.
