  • Publication number: 20250124022
    Abstract: A system classifies an intent based on a received prompt and identifies system-provided prompts based on the intent. The system inputs the system-provided prompts and the received prompt to a generative artificial intelligence model, wherein the generative artificial intelligence model outputs form items corresponding to the received prompt and the system-provided prompts, the form items including form prompt items and form response items. The system converts the form items into the renderable form presentable in a user interface, wherein the renderable form includes the form prompt items and the form response items.

  • Patent number: 12203553
    Abstract: A wear-resistant and low-friction coated piston ring and a preparation method therefor are provided. The OD surface diamond-like carbon coating consists sequentially of a first metal interlayer, a second metal interlayer, a gradient DLC layer, alternating high/low hardness DLC layers, and an outer running-in DLC layer. The side surface diamond-like carbon coating consists sequentially of a metal interlayer, a gradient DLC layer, and alternating high/low hardness DLC layers. The preparation method employs physical vapor deposition to sequentially deposit composite DLC coatings on the OD surface and side surface of the piston ring. The coating is a tetrahedral amorphous carbon structure, exhibiting good thickness uniformity and fine grain structure. This improves the wear resistance of the piston ring's OD surface and side surface, reduces the aggressiveness of the piston ring side surface against the piston ring groove, and meanwhile avoids adhesion.

  • Publication number: 20210403606
    Abstract: The present invention discloses a method for separating and purifying polysaccharides from Ganoderma spores. The method includes ultrasonically extracting defatted Ganoderma spore powder and filtering with a plate and frame filter press to obtain a filtrate, and then precipitating the filtrate by passing sequentially through ethanol with a mass concentration of 75% and ethanol with a mass concentration of 85%, and filtering, to obtain polysaccharides which have a significant inhibitory effect on transplanted tumors in animals.
