  • Patent number: 12641928
    Abstract: Micro-LED structures include an LED epilayer that may be formed before the micro-LED structure is coupled to a backplane substrate. In order to prevent light leakage and maximize light output, the sidewalls and other surfaces of the LED epilayer may be coated with a reflective coating. For example, the reflective coating may include a metal layer that is electrically insulated between dielectric layers from the micro-LED electrodes. The reflective coating may also be formed using multiple layers in a distributed Bragg reflector configuration. This reflective coating may be formed during the LED fabrication process before the micro-LED structure is coupled to the backplane. The pixel isolation structures on the backplane may also include a reflective coating that is applied above the LED epilayers.

  • Publication number: 20250371974
    Abstract: Aspects of the disclosure provide methods of modeling wrong-way driving of road users. For instance, log data including an observed trajectory of a first road user may be accessed. A first set of candidate lane segments for wrong-way driving may be identified from map information. A second set of candidate lane segments for not wrong-way driving may be identified from the map information. For each candidate lane segment in the first set and in the second set, a distance cost between the candidate lane segment and the observed trajectory may be determined. A candidate lane segment may be selected from at least one of the first set or the second set based on the determined distance costs. The selected candidate lane segment may be used to train a model to provide a likelihood of a second road user being engaged in wrong-way driving in a lane.

  • Publication number: 20250347523
    Abstract: To operate an autonomous vehicle, a rail agent is detected in a vicinity of the autonomous vehicle using a detection system. One or more tracks are determined on which the detected rail agent is possibly traveling, and possible paths for the rail agent are predicted based on the determined one or more tracks. One or more motion paths are determined for one or more probable paths from the possible paths, and a likelihood for each of the one or more probable paths is determined based on each motion plan. A path for the autonomous vehicle is then determined based on a most probable path associated with a highest likelihood for the rail agent, and the autonomous vehicle is operated using the determined path.

  • Publication number: 20250318351
    Abstract: A method of forming a micro light-emitting diode (microLED) array may include forming pixel isolation structures on a sacrificial substrate, and mounting the microLEDs on a separate backplane. The processes that forms the pixel isolation structures, and which may damage the backplane or microLEDs can be separately performed on the sacrificial substrate. The pixel isolation structures can then be attached to the backplane and the sacrificial substrate can be removed. This allows the formation of the pixel isolation structures to be isolated, the microLEDs to be tested early in the process, and the interface between the microLEDs and subsequent layers to be free of adhesive.

  • Publication number: 20250296604
    Abstract: The technology relates to controlling a vehicle in an autonomous driving mode in accordance with behavior predictions for other road users in the vehicle's vicinity. In particular, the vehicle's onboard computing system may predict whether another road user will perform a “continuing” lane driving operation, such as going straight in a turn-only lane. Sensor data from detected/observed objects in the vehicle's nearby environment may be evaluated in view of one or more possible behaviors for different types of objects. In addition, roadway features, in particular whether lane segments are connected in a roadgraph, are also evaluated to determine probabilities of whether other road users may make an improper continuing lane driving operation. This is used to generate more accurate behavior predictions, which the vehicle can use to take alternative (e.g., corrective) driving actions.

  • Patent number: 12157501
    Abstract: Methods, systems, and apparatus, including computer programs encoded on a computer storage medium, that obtain scene features in an environment that includes an autonomous vehicle, a first target agent, and a second target agent, and determines whether the first target agent is an emergency vehicle that is active at a current time point. In response to determining that the first target agent is an emergency vehicle that is active at the current time point, an input is generated from the scene features. The input can characterize the scene and indicate that the first target agent is an emergency vehicle that is active at the current time point. Also in response, the input can be processed using a machine learning model that is configured to generate a trajectory prediction output for the second target agent that characterizes predicted future behavior of the second target agent after the current time point.

    Abstract: A method, apparatus, and a non-transitory computer-readable medium storing program code may be provided. The method may include obtaining a first scene space unit in which a dynamic scene element in a scene space is located at a first moment and obtaining a first photographing space unit in which a virtual camera is located in a photographing space at the first moment. The method may also include determining a visibility relationship between the first scene space unit and the first photographing space unit based on prestored visibility data. When the visibility relationship between the first scene space unit and the first photographing space unit is invisible, the method includes removing the dynamic scene element and obtaining remaining dynamic scene elements in the scene space. The method then renders the scene picture in the first moment.
