  • Publication number: 20240330337
    Abstract: A user query, such as a user query processed by the online game system, is provided as input into a trained machine learning model. The machine learning model predicts candidate languages of the user query and outputs language confidence scores for the candidate languages. The user query is also matched with stored query data associated with game information in individual language databases for the respective candidate languages. A match scores may be determined based on a certainty of the respective response matches. The match scores and the language confidence scores may be weighted to determine a weighted score. The weighted scores of the response matches are applied to decide which game information retrieved from the identified database is used in forming a response of search results to the user.

  • Patent number: 11969649
    Abstract: Prominent display of a targeted game in search results from a search within an online gaming platform. In some implementations, a server receives a search query from a device. The search query is executed against a data store of available games to obtain search results indicating a set of games. Based on one or more characteristics of the set of games, it is determined whether the search query is directed to a narrow search for a particular game in the set of games. In response to determining such a narrow search, the particular game is designated with a highlight indication, and the search results and highlight indication are transmitted to the device, causing display of a user interface that includes at least a portion of the search results. The highlight indication causes the device to display an identifier of the particular game as highlighted relative to other search results.

  • Publication number: 20240117122
    Abstract: Provided are a porous silicone resin and a light-weight flexible flame-retardant composite material, belonging to the technical field of nano-porous materials. The porous silicon resin is prepared from a porous silicon resin precursor solution by means of curing and drying processes. The porous silicone resin precursor solution includes a flame retardant, a surfactant, a siloxane monomer, a catalyst, an auxiliary agent and a solvent. The porous silicone resin precursor solution is obtained by firstly dissolving the flame retardant and the surfactant in the solvent, and then adding the siloxane monomer, the catalyst and the auxiliary agent and mixing them uniformly. The porous silicone resin and the light-weight flexible flame-retardant composite material prepared therefrom have the excellent properties of high porosity, high flame retardancy, high elasticity and high strain.

  • Patent number: 10585092
    Abstract: Disclosed are field effect transistor-based (FET-based) sensors for the rapid and accurate detection of analytes both in vivo and in vitro. The FET-based sensors can include a substrate, a channel disposed on the substrate, a source electrode and a drain electrode electrically connected to the channel, and a recognition element for an analyte of interest immobilized on the surface of the channel via a linking group. The distance between the recognition element and the channel can be configured such that association of the analyte of interest with the recognition element induces a change in the electrical properties of the channel. In this way, an analyte of interest can be detected by measuring a change in an electrical property of the channel. Also provided are devices, including probes and multi-well plates, incorporating the FET-based sensors.
