  • Patent number: 10969789
    Abstract: Aspects of the disclosure provide for controlling a vehicle in an autonomous driving mode. For instance, sensor data for an object as well as a plurality of predicted trajectories may be received. Each predicted trajectory may represent a plurality of possible future locations for the object. A grid including a plurality of cells, each being associated with a geographic area, may be generated. Probabilities that the object will enter the geographic area associated with each of the plurality of cells over a period of time into the future may be determined based on the sensor data in order to generate a heat map. One or more of the plurality of predicted trajectories may be compared to the heat map. The vehicle may be controlled in the autonomous driving mode based on the comparison.

  • Publication number: 20210064044
    Abstract: Methods, systems, and apparatus, including computer programs encoded on a computer storage medium, for determining respective importance scores for a plurality of agents in a vicinity of an autonomous vehicle navigating through an environment. The respective importance scores characterize a relative impact of each agent on planned trajectories generated by a planning subsystem of the autonomous vehicle. In one aspect, a method comprises providing different states of an environment as input to the planning subsystem and obtaining as output from the planning subsystem corresponding planned trajectories. Importance scores for the one or more agents that are in one state but not in the other are determined based on a measure of difference between the planned trajectories.

  • Publication number: 20200317819
    Abstract: The present disclosure relates to the field of biological technologies, and discloses a method for expressing and preparing a polyvalent multi-specific antibody and an immune hybrid protein. By using the characteristics of protein Intein, a novel method for preparing a polyvalent specific antibody, a hybrid immune protein having an antibody fused to a cytokine, an immunotoxin having an antibody fused to a toxin, or an immune hybrid protein having an antibody fused to other active proteins is designed and developed. Each portion of a hybrid protein is respectively expressed in a suitable prokaryotic or eukaryotic cell system, separated and purified by high-performance affinity chromatography, and then spliced in vitro by trans-splicing mediated by the intein, to prepare a polyvalent specific antibody and an immune hybrid protein. The method has high production efficiency, and wide scope of application, and facilitates the separation and purification of the products.

  • Patent number: 10685378
    Abstract: An online system aggregates content item from third party systems for presentation to users of the online system. To do so, the online system accesses the web pages of third party systems to trigger tracking pixels that have been previously placed by the third party systems. A triggered tracking pixel sends a server call to the online system that includes tracking pixel data such as information about the content item that was available on the web page. Based on the information gathered through various tracking pixels, the online system generates a catalog of the content item that can then be presented to a user of the online system such that the user can browse content items of the third party system while accessing the online system.

  • Publication number: 20200156632
    Abstract: Methods, systems, and apparatus, including computer programs encoded on a computer storage medium, for identifying high-priority agents in the vicinity of a vehicle. In one aspect, a method comprises processing an input that characterizes a trajectory of the vehicle in an environment using an importance scoring model to generate an output that defines a respective importance score for each of a plurality of agents in the environment in the vicinity of the vehicle. The importance score for an agent characterizes an estimated impact of the agent on planning decisions generated by a planning system of the vehicle which plans a future trajectory of the vehicle. The high-priority agents are identified as a proper subset of the plurality of agents with the highest importance scores.

  • Publication number: 20200159215
    Abstract: Methods, systems, and apparatus, including computer programs encoded on a computer storage medium, for identifying high-priority agents in the vicinity of a vehicle and, for only those agents which are high priority agents, generating data characterizing the agents using a first prediction model. In a first aspect, a system identifies multiple agents in an environment in a vicinity of a vehicle. The system generates a respective importance score for each of the agents by processing a feature representation of each agent using an importance scoring model. The importance score for an agent characterizes an estimated impact of the agent on planning decisions generated by a planning system of the vehicle which plans a future trajectory of the vehicle. The system identifies, as high-priority agents, a proper subset of the plurality of agents with the highest importance scores.

  • Publication number: 20190122037
    Abstract: The technology relates to controlling a vehicle in an autonomous driving mode. For instance, sensor data identifying an object in an environment of the vehicle may be received. A grid including a plurality of cells may be projected around the object. For each given one of the plurality of cells, a likelihood that the object will enter the given one within a period of time into the future is predicted. A contour is generated based on the predicted likelihoods. The vehicle is then controlled in the autonomous driving mode in order to avoid an area within the contour.

  • Publication number: 20170312547
    Abstract: For the delivery of high precision radiation treatment, the accuracy with which a target is irradiated at individual gantry, collimator and patient couch orientation is traditionally verified in 2D. With the QA device described herein, the coverage of the gantry is uniquely measured in 3D. The method of the present invention, combining with the collimator and patient couch measurements, allows the reconstruction of the target coverage in full 3D, which was not possible before. In addition, the method of the present invention can be applied to decompose the traditional quality assurance measurements of combined gantry, collimator and patient couch orientations with standard devices. Such an application provides a comprehensive description of the irradiation accuracy.
