  • Patent number: 11416546
    Abstract: In one embodiment, a method receives a set of frames from a video at a first classifier. The first classifier classifies the set of frames with classification scores that indicate a confidence that a frame contains end credit content using the first classifier using a first model that classifies content from the set of frames. A second classifier then refines the classification scores from neighboring frames in the set of frames using a second classifier using a second model that classifies classification scores from the first classifier. A boundary point is selected between a frame in the set of frames considered not including end credit content and a frame in the set of frames including end credit content based on the refined classification scores.

  • Patent number: 11400959
    Abstract: A surrounding environment of an autonomous vehicle is perceived to identify one or more vehicles nearby. For each of the identified vehicles, based on a current location of the identified vehicle, vehicle-independent information is obtained to determine context surrounding the identified vehicle, where the vehicle-independent information includes vehicle surrounding information that defines physical constraints imposed on the identified vehicle. For each of the identified vehicles, one or more trajectories for the identified vehicle are predicted based at least in part on the vehicle-independent information associated with the identified vehicle. The autonomous vehicle is controlled based on the one or more predicted trajectories of the one or more identified vehicles.

  • Patent number: 11378956
    Abstract: A perception module is configured to perceive a driving environment surrounding an autonomous driving vehicle (ADV) based on sensor data, and to generate perception information using various perception models or methods. The perception information describes the perceived driving environment. Based on the perception information, a planning module is configured to plan a trajectory representing a route or a path for a current planning cycle. The ADV is then controlled and driven based on the trajectory. In addition, the planning module determines a critical region (also referred to as a critical area) surrounding the ADV based on the trajectory in view of a current location or position of the ADV. The metadata describing the critical region is transmitted to the perception module via an application programming interface (API) to allow the perception module to generate perception information for a next planning cycle in view of the critical region.

  • Patent number: 11270869
    Abstract: This invention relates to a plasma chemical vapor deposition microwave resonant cavity, which has a high focusing ability and can be flexibly configured. The resonant cavity is a rotary body formed by two isosceles triangles intersecting at the vertex angles with a Boolean union operation. The base angles of the two triangles are 50°˜75°. Between 2n?˜(2n+0.5) ?, the base lengths of the two triangles are equal or have an n? difference, where n is an integer and ? is the microwave wavelength. The distance between the centroids of the upper and the lower isosceles triangles is 0˜4/5?. A strongly focused electric field can be formed in the cavity by adjusting the base lengths, base angles and centroid distance. Different dielectric windows, microwave coupling modes and gas inlet and outlet modes can be selected in the cavity to fit specific applications. The cavity has simple structures.

  • Patent number: 11118253
    Abstract: Described are techniques for treating metals by exposing the metals to reactive solutions to reduce a temperature of the metal and to modify a surface of the metal through chemical reaction, such as by removing material or adding material. The disclosed techniques may advantageously increase the rate at which the temperature of the metal may be reduced as compared to conventional cooling techniques involving pure water, increase metal manufacturing rates, and reduce overall complexity of a metal manufacturing process. The disclosed techniques may also advantageously expand the range of available surface treatments, allow for faster surface treatment processes, and reduce or eliminate the use of hazardous chemicals during a surface treatment process. Such advantages may arise by employing chemical processing that takes place or takes place more efficiently at elevated temperatures.
