  • Publication number: 20250123626
    Abstract: Training a lexicon of a natural language processing system may include receiving a data set containing a corpus of absolute paths driven by a vehicle annotated with natural language descriptions of said absolute paths and determining parameters of the lexicon based on the data set. The degree to which a path taken by the vehicle satisfies the annotated description may be specified by a scoring function. The lexicon may be determined by finding the lexicon parameters that optimize the degree to which the paths taken by the vehicle satisfy the annotated descriptions. Objects in the environment of the same class are disambiguated by specifying their position relative to other objects using prepositions.

  • Patent number: 12174628
    Abstract: A system for directing the motion of a vehicle, comprising receiving commands in natural language using a processor, the commands specifying a relative path to be taken by the vehicle with respect to other objects in the environment; and determining an absolute path for the vehicle to follow based on the relative path using the processor, the absolute path comprising a series of coordinates in the environment; and directing the vehicle along the absolute path. Also provided is a system for training a lexicon of a natural language processing system, comprising receiving a data set containing a corpus of absolute paths driven by a vehicle annotated with natural language descriptions of the absolute paths using a processor, and determining parameters of the lexicon based on the data set.

  • Patent number: 11828164
    Abstract: A rotary cutting tool for use in a wellbore has an instrumented cutter fitted into a cavity in the tool body. The instrumented cutter body has an outer end portion exposed at the open end of a cavity and is connected to the tool body through at least one connecting section having a smaller cross-section and greater compliance than the outer end portion. The outer end portion and the connecting section are slightly movable within the cavity but the cavity surrounds at least part of the outer end portion sufficiently closely to limit transverse movement to elastic strain of the compliant connecting portion. One or more sensors, which may be strain gauges, are used to measure force on the outer end portion in a plurality of directions transverse to the cavity and causing elastic strain of the at least one connecting section.

  • Patent number: 11074307
    Abstract: Techniques for automatic extraction and verification of location data are disclosed. In some embodiments, a web crawler is configured to identify uniform resource locators (URLs), including a URL for a website associated with a target entity. The web crawler is further configured to fetch a subset of webpages from the website associated with the target entity. The web crawler may restrict the webpages that are fetched from the website based, at least in part, on patterns in the first website that are indicative of where reliable location information may be found. The web crawler further identifies a primary location of the target entity within at least one webpage in the subset of webpages, populating and/or verifying the primary location of the target entity in an entity profile. The entity profile may be consumed by client applications to execute location-aware and/or location dependent functions.

  • Publication number: 20200210412
    Abstract: Among other things, requests are received for tasks to be performed in a database. The tasks include tasks that will cause changes in data of the database and other tasks that must be executed on data in the database that is consistent time-wise. At least some of the data that will be changed by the change-causing tasks comprises data that must remain time-wise consistent for the other tasks. The other tasks are executed in the database while the change-causing tasks are also being executed in the database, without requiring a replication or reconfiguration of the database.

  • Publication number: 20200083541
    Abstract: Electrochemical cells (e.g., fuel cells or electrochemical gas extraction cells) supplied with power-to-gas mixtures of dilute hydrogen concentrations may be remarkably improved by the use of porous gas layer electrodes. The electrochemical cells may comprise a first porous gas layer gas diffusion electrode, a second porous gas layer gas diffusion electrode, and a liquid electrolyte Sin contact with the first and second electrodes. The porous gas layers may each comprise a porous, non-conductive, liquid-impermeable material that dramatically improves cell performance.

  • Patent number: 10397079
    Abstract: A system for evaluating quality of video delivered over a telecommunications network is provided. The system includes one or more monitoring probes coupled to one or more network interfaces providing direct communication between two or more networked devices. The monitoring probes are adapted to capture video data from the network interfaces. The system further includes a processor adapted to analyze the data captured by the monitoring probes. The processor is operatively configured to determine a number of lost data packets within the captured video data. The processor is further operatively configured to determine probability of unrecoverable losses within the captured video based on the determined number of lost data packets. The processor is also operatively configured to calculate a video quality index value based on the determined probability of unrecoverable loses.
