    Abstract: A radar system includes a plurality of radiating elements configured to radiate electromagnetic energy and a plurality of feed waveguides defining a common plane and configured to guide electromagnetic energy to the plurality of radiating elements. The radar system also includes a plurality of waveguides arranged as a dividing network. The dividing network is also configured to split the electromagnetic energy from the source among the plurality of feed waveguides, such that each feed waveguide receives a respective portion of the electromagnetic energy. Additionally, the dividing network is configured to adjust a phase of the electromagnetic energy received by each waveguide. The splitting and adjusting of the dividing network may be based on differences in width between the waveguides of the dividing network and the feed waveguides. The dividing network of waveguides is located in the common plane of the feed waveguides.

    Abstract: The present disclosure is directed to an autonomous vehicle having a vehicle control system. The vehicle control system includes an image processing system. The image processing system receives an image that includes a plurality of image portions. The image processing system also calculates a score for each image portion. The score indicates a level of confidence that a given image portion represents an illuminated component of a traffic light. The image processing system further identifies one or more candidate portions from among the plurality of image portions. Additionally, the image processing system determines that a particular candidate portion represents an illuminated component of a traffic light using a classifier. Further, the image processing system provides instructions to control the autonomous vehicle based on the particular candidate portion representing an illuminated component of a traffic light.

    Abstract: Aspects of the disclosure relate to airbag systems for vehicles. The airbag systems may reduce the secondary impact forces felt by an object upon rebounding from an initial impact with an external airbag by encasing or substantially surrounding the pedestrian with the external airbag. The airbag system may include an external airbag configured to deploy in a vehicle's external environment in order to reduce the likelihood of an object colliding directly with the vehicle and at least one adhesive layer arranged on the external airbag, wherein the adhesive layer is configured to reduce injury caused by a secondary impact of an object upon after an initial impact of the object with the external airbag by causing the object to stick to the external airbag.

    Abstract: Disclosed herein are systems and methods for providing supplemental identification abilities to an autonomous vehicle system. The sensor unit of the vehicle may be configured to receive data indicating an environment of the vehicle, while the control system may be configured to operate the vehicle. The vehicle may also include a processing unit configured to analyze the data indicating the environment to determine at least one object having a detection confidence below a threshold. Based on the at least one object having a detection confidence below a threshold, the processor may communicate at least a subset of the data indicating the environment for further processing. The vehicle is also configured to receive an indication of an object confirmation of the subset of the data. Based on the object confirmation of the subset of the data, the processor may alter the control of the vehicle by the control system.

    Abstract: Aspects of the present disclosure relate to a vehicle for maneuvering a passenger to a destination autonomously. The vehicle includes one or more computing devices that receive a request for a vehicle from a client computing device. The request identifies a first location. The one or more computing devices also determine whether the first location is within a threshold outside of a service area of the vehicle. When the location is within the threshold distance outside of the service area of the vehicle, the one or more computing devices identify a second location within the service area of the vehicle where the vehicle is able to stop for a passenger and based on the first location. The one or more computing devices then provide a map and a marker identifying the position of the second location on the map for display on the client computing device.

    Abstract: A vehicle can be controlled in a first autonomous mode of operation by at least navigating the vehicle based on map data. Sensor data can be obtained using one or more sensors of the vehicle. The sensor data can be indicative of an environment of the vehicle. An inadequacy in the map data can be detected by at least comparing the map data to the sensor data. In response to detecting the inadequacy in the map data, the vehicle can be controlled in a second autonomous mode of operation and a user can be prompted to switch to a manual mode of operation. The vehicle can be controlled in the second autonomous mode of operation by at least obtaining additional sensor data using the one or more sensors of the vehicle and navigating the vehicle based on the additional sensor data.
