  • Publication number: 20220282846
    Abstract: A system includes a first primary optics that receives light from a first light source and projects it onto a transparent shutter and a secondary optics. A second primary optics receives light from the second light source and projects it onto the transparent shutter. The transparent shutter receives light from the first light source via the first primary optics and prevents a lower part of it from entering the secondary optics. The transparent shutter further receives light from the second light source via the second primary optics and projects it onto the secondary optics. The secondary optics receives light from the first primary optics and the transparent shutter and projects it onto a road in front of the vehicle. The transparent shutter includes an air-exposed slit that redirects the light received by the transparent shutter from the second light source toward a middle axis of the transparent shutter.

  • Publication number: 20210181521
    Abstract: A near field line pattern generator includes a double grating and at least one light emitting diode (LED). The double grating includes a first grating and a second grating, each having alternating light blocking sections and light transmitting sections. The LED emits light directed at the double grating assembly such that a first portion of light passes through the first grating, and a second portion of the light passed through the first grating passes through the second grating. The light passing through the second grating forms a line pattern at a focal distance from the double grating assembly. The line pattern has alternating bright portions and dark portions. In some aspects, the pitch of the second grating is less than the pitch of the first grating. In some aspects, the near field line pattern generator also includes a convergent lens for focusing the line pattern at the focal distance.

  • Patent number: 11034286
    Abstract: A vehicle headlamp system includes a vehicle supported power and control system including a data bus. A sensor module can be connected to the data bus to provide information related to environmental conditions or information relating to presence and position of other vehicles and pedestrians. A separate headlamp controller can be connected to the vehicle supported power and control system and the sensor module through the bus. The headlamp controller can include an image frame buffer that can refresh held images at greater than 30 Hz speed. An active LED pixel array can be connected to the headlamp controller to project light according to a pattern and intensity defined by the image held in the image frame buffer and a standby image buffer can be connected to the image frame buffer to hold a default image.

  • Publication number: 20210152719
    Abstract: Multi-color flash with image post-processing that uses a camera device with a multi-color flash and implements post-processing to generate images is described. In one aspect, the multi-color flash with image post-processing may be implemented by a controller configured to control a camera and flashes of at least two different colors. The controller may be configured to cause the camera to acquire a first image of a scene while the scene is being illuminated with the first flash but not the second flash, then cause the camera to acquire a second image of the scene while the scene is being illuminated with the second flash but not the first flash, and generate a final image of the scene in post-processing based on a combination of the first image and the second image.
