  • Publication number: 20250382423
    Abstract: Disclosed are ophthalmic silicone oils, methods of synthesizing such silicone oils, and methods of manufacturing fluid-filled intraocular lenses. The ophthalmic silicone oil can comprise branched polymers comprising a cyclosiloxane core and three or more linear polysiloxane arms linked to the cyclosiloxane core. A method of synthesizing the ophthalmic silicone oil can comprise opening a cyclosiloxane ring with a chlorosilane reagent to yield a linear polysiloxane arm and linking the linear polysiloxane arm to a cyclosiloxane core molecule in a hydrosilylation reaction.

  • Publication number: 20250259323
    Abstract: Methods, systems, and apparatus, including medium-encoded computer program products, for determining video characteristics from videos captured with limited motion cameras. A first set of pairs of images can be selected from a video taken with a limited motion camera. Using the images, a neural network can first be trained for camera parameters while holding the network weights constant. After performing the first training, a second set of pairs of images can be selected from the video. A second training of the neural network can be performed and can include adjusting the camera parameters and the network weights in the neural network. After performing the second training, the camera parameters and the network weights of the neural network can be persisted.

  • Patent number: 12113157
    Abstract: Methods of modifying the composition of layers using selectively absorbing films are described. The composition of a layer can be modified by applying a selectively absorbing film in proximity to the applied coating and components of the layer can be selectively removed to provide a modified layers. The methods can be used to increase the concentration of particles in the layer.

  • Patent number: 11978225
    Abstract: A method includes obtaining a reference image and a target image each representing an environment containing moving features and static features. The method also includes determining an object mask configured to mask out the moving features and preserves the static features in the target image. The method additionally includes determining, based on motion parallax between the reference image and the target image, a static depth image representing depth values of the static features in the target image. The method further includes generating, by way of a machine learning model, a dynamic depth image representing depth values of both the static features and the moving features in the target image. The model is trained to generate the dynamic depth image by determining depth values of at least the moving features based on the target image, the object mask, and the static depth image.

  • Patent number: 11436839
    Abstract: The present disclosure provides systems and methods to detect occluded objects using shadow information to anticipate moving obstacles that are occluded behind a corner or other obstacle. The system may perform a dynamic threshold analysis on enhanced images allowing the detection of even weakly visible shadows. The system may classify an image sequence as either “dynamic” or “static”, enabling an autonomous vehicle, or other moving platform, to react and respond to a moving, yet occluded object by slowing down or stopping.

  • Patent number: 11050948
    Abstract: The present disclosure relates to systems and methods for image capture. Namely, an image capture system may include a camera configured to capture images of a field of view, a display, and a controller. An initial image of the field of view from an initial camera pose may be captured. An obstruction may be determined to be observable in the field of view. Based on the obstruction, at least one desired camera pose may be determined. The at least one desired camera pose includes at least one desired position of the camera. A capture interface may be displayed, which may include instructions for moving the camera to the at least one desired camera pose. At least one further image of the field of view from the at least one desired camera pose may be captured. Captured images may be processed to remove the obstruction from a background image.
