  • System and method for processing video data to detect and eliminate flickering light sources through dynamic exposure control
    Patent number: 10412312
    Abstract: An image capture system is provided for a vehicle equipped with a display for displaying streamed video images of a scene proximate the vehicle. The image capture system includes a camera for capturing video images of the scene proximate the vehicle at a selected exposure time and streaming the video images, and an image processing unit for receiving the streamed video images, processing the streamed video images and supplying the streamed video images to the display. The image processing unit is configured to detect amplitude-modulated light sources in the streamed video images, and adjust the exposure time of the camera to match a multiple of a modulation frequency of the amplitude-modulated light sources decreasing a flicker intensity of the amplitude-modulated light sources in the streamed video images supplied to the display.

  • Laser process with controlled polarization
    Patent number: 10369663
    Abstract: A laser system and method includes control of the direction of polarization of a laser beam that forms laser-induced channels in a substrate along a process path. Control of the direction of polarization is useful while forming laser-induced channels in substrate materials having a crystalline component. An optical element, such as a waveplate, imparts the laser beam with a direction of polarization that is controllable with respect to an axis of the substrate when the substrate is supported by the system for processing. The direction of polarization is changeable and controllable with respect to the direction of the process path and/or a crystalline plane of the substrate via movement of the optical element or the substrate or both.
