  • Patent number: 11884291
    Abstract: Aspects of the disclosure provide for the determining whether to assign a driver to a trip. For instance, a route for a trip between a pickup location and a destination location for a passenger may be determined. Branch routes for the route may be determined based on one or more lane changes of the route. A probability of following each determined branch route may be determined. A probability of requiring assistance for each determined branch route may be determined. Whether to assign a driver to the trip may be determined based on the probabilities for each determined branch route. A vehicle of a fleet of vehicles may be assigned to the trip based on the determine of whether to assign a driver.

  • Publication number: 20230388024
    Abstract: Photonic interposers that enable low-power, high-bandwidth inter-chip (e.g., board-level and/or rack-level) as well as intra-chip communication are described. Described herein are techniques, architectures and processes that improve upon the performance of conventional computers. Some embodiments provide photonic interposers that use photonic tiles, where each tile includes programmable photonic circuits that can be programmed based on the needs of a particular computer architecture. Some tiles are instantiations of a common template tile that are stitched together in a 1D or a 2D arrangement. Some embodiments described herein provide a programmable physical network designed to connect pairs of tiles together with photonic links.

  • Patent number: 11685408
    Abstract: Aspects of the disclosure provide for the generation of a driving difficulty heat map for autonomous vehicles. For instance, log data generated by a vehicle being driven in a manual driving mode for a segment of a route may be input into a disengage model in order to generate an output identifying a likelihood of a vehicle driving in an autonomous driving mode requiring a disengage from the autonomous driving mode along the segment of the route. The log data may have been collected within a geographic area. A grid for the geographic area may be generated. The grid may include a plurality of cells. The output is assigned to one of the plurality of cells. The plurality of cells and assigned output may be used to generate a driving difficulty heat map for the geographic area.

  • Publication number: 20220413510
    Abstract: Aspects of the disclosure provide a method of providing a destination to an autonomous vehicle in order to enable the autonomous vehicle to collect data according to a targeted driving goal. For instance, a current location of an autonomous vehicle may be received. A set of destinations may be selected from a plurality of predetermined destinations. A route may be determined for each destination. A relevance score may be determined for each destination based on the determined routes and the targeted driving goal. Each destination may be assigned to one of a set of two or more buckets based on the relevance scores. A destination of the set may be selected based on a predetermined sampling probability. The selected destination is sent to the autonomous vehicle in order to cause the autonomous vehicle to travel to the selected destination in an autonomous driving mode.

  • Publication number: 20220292716
    Abstract: Systems and methods for detecting crop marks depicted in digital images are disclosed. According to certain aspects, an electronic device detects a set of crop marks in a reference digital image and aligns the reference digital image with an input digital image. Based on locations of the detected crop marks as aligned to the input digital image, the electronic device detects a set of partial crop marks in the input digital image. As a result, the partial crop marks in the input digital image may be removed.

  • Patent number: 10783189
    Abstract: Among other things, this document describes a computer-implemented method for storing and retrieving information about the locations of objects. The method can include receiving a first query that includes one or more terms identifying an object. The first query can be determined to include a command to store location information for the object. The first query can be parsed to determine identifying information for the object, and a location can be determined for the object. The method further includes identifying one or more attributes of the object that are not specified in the first query, and causing a first set of data to be stored that characterizes the identifying information for the objet, the location of the object, and the one or more attributes of the object.

  • Patent number: 10282833
    Abstract: Optical verification testing of an IC includes obtaining images of the IC by, for each image: (i) illuminating the IC with excitation light, wherein the excitation light corresponds to a respective specific optical excitation of a predefined spectrum of optical excitations (e.g., wavelength spectrum); and (ii) detecting scattered light from the IC in response to the specific optical excitation. For each of a set of sub-regions of the images, the respective sub-region is mapped to at least one of (i) a specific sub-unit of a predefined set of sub-units (e.g., gates) of the IC and (ii) a null result, thereby creating a representation of a detected layout of the IC as an arrangement of the sub-units. The representation can be used to verify that an as-fabricated layout is consistent with an as-designed layout, to detect unauthorized modifications of the IC structure.
