  • Patent number: 11441089
    Abstract: Distillate boiling range and/or diesel boiling range compositions are provided that are formed from crude oils with unexpected combinations of high naphthenes to aromatics weight and/or volume ratio and a low sulfur content. This unexpected combination of properties is characteristic of crude oils that can be fractionated to form distillate/diesel boiling range compositions that can be used as fuels/fuel blending products with reduced or minimized processing. The resulting distillate boiling range fractions and/or diesel boiling range fractions can have an unexpected combination of a high naphthenes to aromatics weight and/or volume ratio, a low but substantial aromatics content, and a low sulfur content.

  • Patent number: 11429664
    Abstract: A computer vision processor of a camera extracts attributes of persons or vehicles from hyperzooms generated from image frames. The hyperzooms represent traffic patterns. The extracting is performed using a feature extractor of an on-camera convolutional neural network (CNN) including an inverted residual structure. The attributes include at least colors of clothing of the persons or colors of the vehicles. Mobile semantic segmentation models of the CNN are generated using the hyperzooms and the attributes. Attribute analytics are generated by executing the mobile semantic segmentation models while obviating network usage by the camera. The attribute analytics are stored in a key-value database located on a memory card of the camera. A query is received from the server instance specifying one or more of the attributes. The attribute analytics are filtered using the one or more of the attributes to obtain a portion of the traffic patterns.

  • Publication number: 20220270871
    Abstract: Methods for pre-cleaning substrates having metal and dielectric surfaces are described. The substrate is exposed to a strong reductant to remove contaminants from the metal surface and damage the dielectric surface. The substrate is then exposed to an oxidation process to repair the damage to the dielectric surface and oxidize the metal surface. The substrate is then exposed to a weak reductant to reduce the metal oxide to a pure metal surface without substantially affecting the dielectric surface. Processing tools and computer readable media for practicing the method are also described.

    Abstract: Methods and systems are disclosed for mapping the coordinate systems of devices for AR applications. A third device may receive a first pose from a first device associated with a first coordinate system and a second pose from a second device associated with a second coordinate system. The third device may receive an image that includes fiducial markers presented by each of the first device and the second device. The first pose and the portion of the image including the first fiducial marker may define a first set of 3D coordinates. The second pose and the portion of the image including the second fiducial marker may define a second set of 3D coordinates. A coordinate-system transform can be generated from a correspondence between the first set and the second of 3D coordinates.

  • Publication number: 20220230383
    Abstract: Techniques for occlusion and collision detection in an AR session are described. In an example, a depth sensor is used to generate a depth image. Distortions in the depth image are reduced or eliminated by at least dividing the depth image into depth layers and moving depth pixels between the layers. An RGBD image is generated from the depth image, as updated, and an RGB image generated at substantially the same time as the depth image. Occlusion of a virtual object is detected based on the RGBD image. Further, a 3D model of the real-world environment is generated from the depth images, as updated, and includes multi-level voxels. Collision with the virtual object is detected based on the multi-level voxels. Rendering of the virtual object in an AR session is based on the occlusion and collision detection.
