Abstract: Data-sharding systems and/or methods for cost- and time-efficient record search are described. Data-sharding embodiments utilize a name-sharding dimension, optionally in combination with one or more additional dimensions such as record type and year, to reduce latency and reduce search-associated costs. The data-sharding systems and methods embodiments utilize an optimization algorithm to determine a distribution of records related to names. The optimization algorithm may use a three-character prefix for surnames in records to distribute shards across documents, with specific shards relating to no-name and multi-name records allocated.

Abstract: A kart having a pedal speed controller and other components and arrangements thereof are disclosed. The kart can be provided with a controller for controlling speed; the pedal speed controller comprising a pedestal and a pedal, one end of the pedal is articulated with the pedestal and keeps a certain angle with the pedestal. The pedal speed controller also comprises a sensor connected with the controller, and the sensor can obtain displacement signal along the tread direction of the pedal. The pedal speed controller has the advantages of realizing pedal control of acceleration or deceleration for drivers, avoiding interference with manual adjustment of kart direction, preventing from mutual influence between speed regulation and steering, improving the speed control performance of the kart, and improving the driving experience.

Abstract: Search-result explanation systems, methods, and computer-program products receive a user search query, expand the search query into a plurality of sub-queries, perform a database search using the expanded user search query, and determine which sub-queries of the plurality of sub-queries matched with a particular search result. Results from the database search are re-indexed in an index generated on-the-fly and in-memory, within which the results are searched using the sub-queries to determine matching fields and match types. A score is determined based on the type of match(es) with a particular search result based on one or more predefined weights and normalized using a denominator comprising a fictitious, on-the-fly record configured to receive a perfect score according to the received user search query. A user interface showing ranked results and explanations for the ranking, including a score for the result based on the expanded user search query.

Abstract: The present disclosure is directed toward systems, methods, and non-transitory computer-readable media for utilizing a sophisticated lifespan filter algorithm for searching genealogical databases to accurately identify genealogical records that match a record query. For example, utilizing the lifespan filter algorithm, the disclosed systems can access and analyze data pertaining to relatives of candidate records (e.g., genealogical records that could match a record query). In some cases, for a given candidate record, the disclosed systems access genealogical data fields for a spouse, one or both parents, and/or one or more children of the individual represented by the candidate record. From the relative-data fields, the disclosed systems can determine a record lifespan for the candidate record and can compare the record lifespan with a query lifespan of the record query to determine whether the candidate record matches the record query.

Abstract: Various powered personal mobility vehicles are disclosed. In some embodiments, the vehicle can include a deck having a forward portion, a rearward portion, and a neck portion. A front swivel wheel assembly and a rear swivel wheel assembly can be connected with the deck. In some embodiments, the front swivel wheel assembly comprises a motor.

Abstract: A genealogy online system may cause to display, at a graphical user interface associated with a genealogy online system, a search box, the genealogy online system configured to provide functions comprising family-tree building and historical record search. The genealogy online system may receive a query from a user entered at the search box. The genealogy online system may use a machine learning language model to determine an intent of the user associated with the query. The genealogy online system may cause to display, at the graphical user interface as a result of the query, one or more links to one or more functions of the genealogy online system based on the intent determined by the machine learning language model.

Abstract: Image-faceted search systems and/or methods are described. Image-faceting embodiments receive genealogy records certain of which are imaged genealogy records associated with an image. Metadata of the imaged genealogy records are determined or extracted and used to assign the image genealogy records to one or more categories and optionally subcategories. Machine learning may be used to extract the metadata and/or to categorize the records, along with in embodiments a translation algorithm. A user faceted search query is received, with pertinent search results filtered according to a selected facet, such as an image facet, and according to filtering criteria. The filtered search results, including images matching the faceted search query, are presented to a user.
