Patent number: 11930569Abstract: An LED matrix lighting device for illuminating a lighting pattern with even intensity. The LED matrix lighting device includes a plurality of LEDs, a collimating lens in front of each LED for collimating light of the LED, and a light refracting element in front of collimating lenses arranged to refract light of at least a first part of the LEDs with a different refraction angle than at least a second part of the LEDs. The disclosure further relates to a machine vision system, a method, and a computer program product.Type: GrantFiled: November 16, 2020Date of Patent: March 12, 2024Assignee: Procemex OyInventor: Jari Ritoniemi

Publication number: 20230228691Abstract: A smart synchronizing method of a web inspection system for monitoring a moving web. A synchronizing device, at least one slave camera, and at least one lighting device illuminate an area of the web arranged to be imaged by the cameras. The method includes transmitting a synchronizing signal to the slave camera. The synchronizing signal includes at least a start pulse and serial data including additional information. All the cameras are synchronized with each other based on synchronization moment when integration of cameras end. A light synchronizing signal is transmitted to the at least one lighting device indicating a switching on and off times of the at least one lighting device, which switching off time corresponds to the synchronization moment, and calculating a starting time of integration based on an individual integration time of a camera and the synchronization moment common for cameras of the web inspection system.Type: ApplicationFiled: June 15, 2021Publication date: July 20, 2023Applicant: Procemex OyInventor: Jari RITONIEMI

Patent number: 11128808Abstract: The invention relates to a method for illuminating a wood fibre web for deviation detection. The method comprises turning on LEDs of an overhead sidelight that are side-directed towards a first edge of the web for illuminating a first half of width of the web, capturing an image of the first half, turning off the LEDs, turning on LEDs of the overhead sidelight that are side-directed towards a second edge of the web for illuminating a second half of width of the web, capturing an image of the second half, and turning off the LEDs. The invention also relates to an overhead sidelight, a machine vision system, and a lighting system.Type: GrantFiled: December 3, 2019Date of Patent: September 21, 2021Assignee: Procemex OyInventor: Jari Ritoniemi
