  • Patent number: 6871785
    Abstract: The method for compensating undesired variations in an electrical signal generated by a sensor of an optical code reader comprises the steps of generating an envelope signal starting from the electrical signal generated by the sensor and normalizing the electrical signal with respect to the envelope signal. Preferably, the envelope signal is filtered with a low-pass filter before being normalized so as to eliminate steps and edges which may cause distortions during normalization, and the normalized signal is amplified in a controlled way so as to supply an output signal ranging between two values having preset amplitudes. Normalization is carried out by dividing, point by point, the electrical signal by the envelope signal, in the case of continuous analog processing; alternatively, in presence of discrete-time signals, normalization is carried out by subtracting the envelope signal from the electrical signal.

  • Patent number: 6443360
    Abstract: There are described a method and a device for focusing an analogue electrical signal representative of an optical code, which selectively emphasize the highest frequencies of the electrical signal. The emphasis is performed with linear phase, so that the relative positions of the peaks and valleys of the focused analogue electrical signal substantially remain unchanged. The focusing can comprise low-pass, high-pass and band-pass filtering. The focusing can be variable, and in particular, automatically variable.
