  • Patent number: 11703873
    Abstract: Various technologies described herein pertain to generating an occupancy grid movie for utilization in motion planning for the autonomous vehicle. The occupancy grid movie can be generated for a given time and can include time-stepped occupancy grids for future times that are at predefined time intervals from the given time. The time-stepped occupancy grids include cells corresponding to regions in an environment surrounding the autonomous vehicle. Probabilities can be assigned to the cells specifying likelihoods that the regions corresponding to the cells are occupied at the future times. Moreover, cached query objects that respectively specify indices of cells of a grid occupied by a representation of an autonomous vehicle at corresponding orientations are described herein. An occupancy grid for the environment surrounding the autonomous vehicle can be queried to determine whether cells of the occupancy grid are occupied utilizing a cached query object from the cache query objects.

  • Publication number: 20230184628
    Abstract: A vehicle is received in a stationary controlled area of a controlled testing environment. Simulation inputs corresponding to a simulated scene are generated and transmitted to the vehicle. The vehicle applies torque in response. A vehicle control mechanism of the controlled testing environment, such as a chassis dynamometer, a motorized treadmill, or a lift, keeps the vehicle within the stationary controlled area during the test despite the torque applied by the vehicle. A path of the vehicle within the simulated scene is determined based on the applied torque, based upon which the vehicle's navigation system is calibrated.

  • Patent number: 11023855
    Abstract: Techniques for generating an electronic request based on sensor data of an ARD are described. In an example, a computer system receives a message from the ARD The message includes the sensor data and an identifier of the ARD. The computer system identifies the item from a profile associated with the ARD based on the identifier, and determines an amount of the item stored by the ARD based on the sensor data. Further, the computer system generates the electronic request for a replacement amount of the item based on the amount of the item, on a rule, and on a constraint. The electronic request identifies the item and the ARD. The rule specifies a customization of the electronic request based on the item. The constraint specifies a limit on the customization based on the identifier. The computer system causes a delivery of the replacement amount based on the electronic request.

  • Patent number: 10853870
    Abstract: Techniques for identifying an automatic replenishment device (ARD) to item pairing based on an interaction by a user with a component of the ARD are disclosed herein. In embodiments, information from an ARD may be received that corresponds to an identify request based at least in part on an interaction with a component of the ARD. The information may include a device identifier for the ARD and a registration token. ARD data that identifies the ARD and the item associated with the ARD may be determined based at least in part on the received information. In accordance with at least one embodiment, a notification may be generated based at least in part on the ARD data where the notification is configured to present the item associated with the ARD. The notification may be transmitted to a user device associated with the ARD.

  • Patent number: 10845806
    Abstract: Various technologies described herein pertain to controlling an autonomous vehicle to suppress data corresponding to predefined static objects in a radar output generated by a radar sensor system. A computing system of the autonomous vehicle retrieves prior data for a geographic location from a prior radar space map. The prior radar space map includes prior data for geographic locations in an environment corresponding to whether predefined static objects to be suppressed in radar outputs are located at the geographic locations. The computing system generates a score representative of a likelihood of a tracked object being at the geographic location based on data from the radar output for the geographic location, data from an output of a second sensor system for the geographic location, and the prior data for the geographic location from the prior radar space map. An engine, braking system, and/or steering system are controlled based on the score.
