  • Patent number: 12284591
    Abstract: Methods, systems, and devices for wireless communications are described. In some communications systems, interference may impede signaling between a base station and a target user equipment (UE) such that a base station may identify a donor UE to relay communications to the target UE. The donor UE may receive a coded data packet from the base station, and may identify a radio network temporary identifier (RNTI) scrambling code for the packets addressed to the target UE. In cases where the donor UE identifies that the packet has an RNTI scrambling code associated with the target UE, the donor UE may forward the coded data packet to the target UE base on the RNTI scrambling code. Such early detection of data packets addressed to the target UE may allow for the UE to forward a data packet without fully decoding the packet.

  • Publication number: 20240309225
    Abstract: The present disclosure provides an antifouling coating and a use method and use thereof. In the antifouling coating of the present disclosure, polyaspartic acid ester is an isocyanate curing agent containing a secondary amine structure. An ester group and aliphatic properties in the polyaspartic acid ester can increase wear resistance of the coating. The polyaspartic acid ester is combined with a polyisocyanate-containing prepolymer in a component A to endow the antifouling coating with desirable toughness and elasticity, such that the antifouling coating has excellent impact and abrasion resistance. In the component A, a polydimethylsiloxane structure is introduced into the hydroxypropyl silicone oil-based isocyanate prepolymer. The polydimethylsiloxane structure can generate microphase separation with a polyurea hard segment and migrate to a surface of the coating, thereby reducing surface energy of the coating to reduce an adhesion between fouling organisms and an interface.

  • Patent number: 12001798
    Abstract: A system performs named entity recognition for performing natural language processing, for example, for conversation engines. The system uses context information in named entity recognition. The system includes the context of a sentence during model training and execution. The system generates high quality contextual data for training NER models. The system utilizes labeled and unlabeled contextual data for training NER models. The system provides NER models for execution in production environments. The system uses heuristics to determine whether to use a context-based NER model or a simple NER model that does not use context information. This allows the system to use simple NER models when the likelihood of improving the accuracy of prediction based on context is low.
