  • Patent number: 5548109
    Abstract: A wide bandwidth slope detector has a comparator with first and second time constant circuits coupled to first and second inputs thereof. Where one time constant is on the order of three times the other, the comparator will change state in response to the slopes of an input analog signal coupled to the time constant circuit. Feedback can be provided by a fixed resistor or by a tracking circuit. A smoothing or clipping circuit can be used to pre-process the input analog signals to eliminate noise therefrom. A bar code reading system combines first and second clipping circuits to smooth the highs and lows of the input signal, coupled to a slope detector. The tracking circuit can be used to provide a symmetrical hysteresis characteristic.

  • Patent number: 5545885
    Abstract: Method and apparatus are used to detect and identify coded patterns on articles such as bank notes, in the form of magnetic regions (e.g., small areas printed with ink containing magnetic pigment). The apparatus includes a mechanism for passing a given article rapidly past a scanning location where a "write" magnetic head and its associated circuitry applies one or more recording signals (of a suitably high frequency) to these regions. The thus magnetized regions are then immediately sensed by a highly sensitive "read" head. The circuitry associated with the read head selectively amplifies the high frequency signals recorded on the magnetic regions. This further improves the signal-to-noise (S/N) ratio. It then compares the phases of the detected signals with a reference signal fed-forward from the write head circuitry. This further improves the accuracy of detecting the presence or absence of magnetized regions.
