Patent number: 12212845Abstract: Passive autofocusing is used in image acquisition devices (e.g., machine-readable symbol readers, cameras), and can be employed with shutter and/or event-based image sensors. An aimer pointer is easily detected in images, and one or more characteristics characterized at various focus positions of the optics. A size of a characteristic dimension and/or shape of the aimer pointer and/or a measure of sharpness of the aimer pointer is used to determine which image, and hence focus position, results in an optimized or even optimum (i.e., best) focus. The image acquisition system is then configured accordingly. Measuring aimer pointer size is typically less computationally intensive than conventional approaches. Use of a laser beam to produce the aimer pointer usually requires lower exposure time than other approaches. Image data can advantageously be windowed using a relatively small region of interest (ROI) based on a known aimer pointer position.Type: GrantFiled: September 6, 2022Date of Patent: January 28, 2025Assignee: Datalogic IP Tech, S.r.l.Inventors: Luca Perugini, Simone Spolzino

Patent number: 12175324Abstract: A photoelectric sensor includes an emitter that emits a plurality of light beams. Fractions thereof pass through transparent portions of a first body and a second body in series before intersecting an optically powered surface, which directs the fractions to a target focusing an image that passes through a perimeter of the first body in one direction and focusing an image that passes through a perimeter of the second body in a perpendicular direction. The emitter, first and second bodies, and the optically powered surface are positioned so as to form a light spot on the target within which the fractions of the plurality of light beams substantially overlap.

Patent number: 12154185Abstract: The disclosure relates to a system and method for verifying robot data that is used by a safety system monitoring a workspace shared by a human and robot. One or more sensors monitoring the workspace are arranged to obtain a three-dimensional view of the workspace. Raw data from each of the sensors is acquired and analyzed to determine the positioning and spatial relationship between the human and robot as both move throughout the workspace. This captured data is compared to the positional data obtained from the robot to assess whether discrepancies exist between the data sets. If the information from the sensors does not sufficiently match the data from the robot, then a signal from the system may be sent to deactivate the robot and prevent potential injury to the human.Type: GrantFiled: December 22, 2021Date of Patent: November 26, 2024Assignee: Datalogic IP Tech S.r.l.Inventors: Gildo Andreoni, Matteo Selvatici, Mohammad Arrfou

Publication number: 20230401403Abstract: Systems and methods for reading machine-readable indicia (e.g., barcodes) can include emitting, by a code reading device, a light to illuminate a surface including a machine-readable indicia. The code reading device can capture an image of the machine-readable indicia, and determine whether an image quality parameter of the image of the machine-readable indicia captured by the image sensor satisfies a predefined condition (e.g., no reflections on the machine-readable indicia). Based on a determination that the image quality parameter of the image of the machine-readable indicia does not satisfy the predefined condition, the voltage being applied to the electrochromic component may be adjusted to cause an opacity level of the electrochromic component to be altered. Otherwise, the voltage being applied to the electrochromic component may remain unchanged.Type: ApplicationFiled: June 13, 2022Publication date: December 14, 2023Applicant: Datalogic IP Tech S.r.l.Inventors: Simone Stefanini, Davide Gavioli, Michele Suman
