ABSTRACT:
A device for reading an item of information defined by a plurality of different intervals between consecutive elements on a data carrier, and corresponding methods of recognizing an item of information defined by a plurality of different intervals between consecutive pulses of a first pulsed signal. The device includes first and second element detectors arranged for motion relative to the elements on the data carrier, which detectors generate responses to the elements. The element detectors are spaced from each other by a distance e such that the responses to each element generated by said second element detector have a time delay e corresponding to the physical distance e with respect to the responses generated by said first element detector. The device further includes means for comparing the response of said first and second element detectors to produce an output signal representing the item of information. The distance e is selected and the comparison is such that a first interval a is identified when the beginning of a response by said second element detector occurs during a response by said first element detector, and a second interval b is identified when the end of a response by said first element detector occurs during a response by said first element detector.
