Patent number: 11922261Abstract: An image based code reader comprises an image sensor. The image sensor is configured to acquire an image of a code. Additionally, the image based code reader includes a lens configured to project an image scene including the code onto the image sensor, the lens comprising a variable optical power that controls a focus distance of the image based code reader. The image based code reader further includes a processor operatively coupled to the image sensor and the lens. The processor is configured to acquire the image of the code using only pixels located within a region of interest of the sensor, and a size of the region of interest is selected based on the focus distance of the reader.Type: GrantFiled: December 23, 2019Date of Patent: March 5, 2024Assignee: Cognex CorporationInventors: Pepe Fernandez-Dorado, Saul Sanz Rodriguez, Laurens Nunnink, Richard Reuter

Patent number: 11681081Abstract: Systems and methods reduce temperature induced drift effects on a liquid lens used in a vision system. A feedback loop receives a temperature value from a temperature sensor, and based on the received temperature value, controls a power to the heating element based on a difference between the measured temperature of the liquid lens and a predetermined control temperature to maintain the temperature value within a predetermined control temperature range to reduce the effects of drift. A processor can also control a bias signal applied to the lens or a lens actuator to control temperature variations and the associated induced drift effects. An image sharpness can also be determined over a series of images, alone or in combination with controlling the temperature of the liquid lens, to adjust a focal distance of the lens.Type: GrantFiled: September 14, 2021Date of Patent: June 20, 2023Assignee: COGNEX CORPORATIONInventors: Esther Oteo, Andreas Weber, Saul Sanz Rodriguez, Jens Ruetten, Pepe Fernandez-Dorado

Patent number: 11630962Abstract: This invention provides an aimer assembly for a vision system that is coaxial (on-axis) with the camera optical axis, thus providing an aligned aim point at a wide range of working distances. The aimer includes a projecting light element located aside the camera optical axis. The beam and received light from the imaged (illuminated) scene are selectively reflected or transmitted through a dichoric mirror assembly in a manner that permits the beam to be aligned with the optical axis and projected to the scene while only light from the scene is received by the sensor. The aimer beam and illuminator employ differing light wavelengths. In a further embodiment, an internal illuminator includes a plurality of light sources below the camera optical axis. Some of the light sources are covered by a prismatic structure for close distance, and other light sources are collimated, projecting over a longer distance.Type: GrantFiled: June 28, 2021Date of Patent: April 18, 2023Assignee: Cognex CorporationInventors: Laurens Nunnink, Saul Sanz Rodriguez

Publication number: 20230063329Abstract: A method for an imaging module can include rotating an imaging assembly that includes an imaging device about a first pivot point of a bracket to a select first orientation, fastening the imaging assembly to the bracket at the first orientation, rotating a mirror assembly that includes a mirror about a second pivot point of the bracket to a select second orientation, and fastening the mirror assembly to the bracket at the second orientation. An adjustable, selectively oriented imaging assembly of a first imaging module can acquire images using an adjustable, selectively oriented mirror assembly of a second imaging module.Type: ApplicationFiled: August 24, 2022Publication date: March 2, 2023Inventors: Saul Sanz Rodriguez, Tony Depre, Jens Ruetten, Laurens Nunnink

Patent number: 11574137Abstract: This provides an ID reader, typically configured for handheld operation, which integrates three types of illumination into a compact package that generates robust performance and resistance to harsh environmental conditions, such as dust and moisture. These illumination types include, direct (diffuse) light, low-angle light and polarized light. The ID reader includes a sealed reader module assembly having the illuminators in combination with an imager assembly (optics and image sensor) at its relative center. Additionally, also an on-axis aimer and a variable focus system with liquid lens have been integrated in this module and is placed on axis using a mirror assembly that includes a dichroic filter. As the optimal distance to read a code with low-angle light is typically shorter than the optimal distance to use the polarized illumination a variable (e.g. liquid) lens can adjust the focus of the reader to the optimal distance for the selected illumination.Type: GrantFiled: May 10, 2021Date of Patent: February 7, 2023Assignee: Cognex CorporationInventors: Jose Fernandez Dorado, Laurens Nunnink, Saul Sanz Rodriguez, Kai Fluegge, Yasin Salih Ciftci
