Patent number: 10762314Abstract: A code reader may include a light source configured to illuminate a machine-readable indicia representative of a standard code associated with an item. An image sensor may be configured to receive an image of the machine readable indicia. An illumination source may be configured to illuminate an anti-counterfeiting key that, when illuminated by the illumination source, reflects the illumination from the illumination source to be incident on the image sensor. A processing unit may be in electrical communication with the image sensor, and may be configured to decode the standard code of the machine-readable indicia and check validity of the reflected illumination from the anti-counterfeiting key.Type: GrantFiled: May 10, 2017Date of Patent: September 1, 2020Assignee: Datalogic IP Tech S.r.l.Inventors: Michele Suman, Giulio Berzuini, Maurizio Bianchi

Patent number: 6871785Abstract: 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.Type: GrantFiled: December 19, 2000Date of Patent: March 29, 2005Assignee: Datalogic S.p.AInventors: Marco Piva, Maurizio Bianchi
