  • Publication number: 20200223429
    Abstract: A vehicular sensing system includes a plurality of sensors disposed at a vehicle so as to have a combined field of sensing forward, rearward and sideward of the vehicle. Data captured by the sensors is processed at a control to detect objects present in a respective field of sensing. A control designates a plurality of locations within the fields of sensing. As the vehicle moves along the road, the control increases a value for each designated location when an object is detected at that designated location and decreases the value for each designated location when an object is not detected at that designated location. The control, as the vehicle moves along the road, generates an object map based on values for the designated locations. The greater the value for a particular designated location, the greater the probability an object is present at that particular designated location.

  • Publication number: 20200179821
    Abstract: Hydrophobic particles such as coal and hydrophobized mineral fines can be readily separated from hydrophilic impurities by forming agglomerates in water using a hydrophobic liquids such as oil. The agglomerates of hydrophobic particles usually entrap large amounts of water, causing the moisture of the recovered hydrophobic particles to be excessively high. This problem can be overcome by dispersing the hydrophobic agglomerates in a hydrophobic liquid that can be readily recycled. The dispersion can be achieved using specially designed apparatus and methods that can create a turbulence that can help destabilize the agglomerates in a recyclable hydrophobic liquid and facilitate the dispersion.

  • Publication number: 20200160167
    Abstract: An automatic tag identification system identifies tags for color themes, a color theme referring to a set of multiple colors that work well together to create (e.g., are visually appropriate for creating) a desired effect, and a tag referring to one or more words that describe a color theme. The automatic tag identification system receives an indication of the multiple colors (e.g., five colors) for a color theme. A first machine learning system uses the indicated multiple colors to generate a color theme embedding for the color theme, which is a vector encoding or embedding of the color theme. The second machine learning system uses the color theme embedding generated by the first machine learning system to generate one or more tags that label the color theme. These one or more tags can then be saved as associated with or corresponding to the multiple colors for the color theme.
