Patents by Inventor Giuseppe Stanzani

Giuseppe Stanzani has filed for patents to protect the following inventions. This listing includes patent applications that are pending as well as patents that have already been granted by the United States Patent and Trademark Office (USPTO).

  • Laer-beam bar code reader
    Patent number: 5446267
    Abstract: Bar code reader including two sources which are enabled to emit respective laser beams with a cyclic alternation; the laser beams are focused by optical elements on two different regions of a read area. Reflected rays from the read area are processed by a decoding unit operatively connected to the laser-beam sources so that when the presence of a code in the read area is detected, only the laser beam which is focused on the region in which the bar code is present remains enabled.
    Type: Grant
    Filed: February 3, 1994
    Date of Patent: August 29, 1995
    Assignee: Datalogic S.p.A.
    Inventors: Giuseppe Stanzani, Claudio Mazzone
  • Photoelectric barrier, particularly useful as an accident-preventing device in machine tools
    Patent number: 4310836
    Abstract: A photoelectric barrier comprises an emitter emitting a movable modulated beam which scans periodically at a high rate an area to be protected. The beam is then redirected to a photoelectric receiver supplying the signal deactivating the machine controls. The barrier also comprises a circuit generating pulses which are effective to suppress some of the pulses emitted by the photoelectric emitter in order to monitor the machine operation during scanning, the suppression pulses being produced by detecting the correct rotation of the scanning motor.
