  • Publication number: 20250353246
    Abstract: An embossing method for floor tiles makes thermoplastic polymer material in a floor tile to be embossed be converted into a viscous flow state by an ultrasonic embossing device, and embosses a floor tile modeling and a floor tile pattern on the floor tile to be embossed at the same time, such that the floor tile modeling and the floor tile pattern are not prone to rebound after being formed by embossing, stability of embossing of the edge of the floor tile is greatly improved, and yield rate of the floor tile increases. Additionally, the ultrasonic embossing device in the present application can further configure an ultrasonic welding head as a first welding head or a second welding head according to the floor tile modeling and the floor tile pattern, thereby meeting many types of different requirements for embossing patterns and reducing development cost of production lines.

  • Publication number: 20250250532
    Abstract: This invention concerns an integrated microfluidic system that utilizes microfluidic chip technology to receive a patient sample including cells, expand the cells, reprogram the expanded cells and then store the reprogrammed cells in a microfluidic chip. These microfluidic chips with stored reprogrammed cells may then be used in scenarios of genetic differentiation into specific cell types. Overall this system and workflow is suitable as a hospital based device that will allow the generation of iPSCs from every patient for downstream diagnostic or therapeutic use.

  • Patent number: 11751713
    Abstract: The embodiment relates to the convenient amateur creation of a beverage where the extraction of flavor into a solvent is obtained using ultrasound. Where the solvent and solute are held in a removable carafe which has an ultrasound transducer. A control system will trigger ultrasound into the solvent for specific durations in order to quickly create the desired outcome. The use of one or more computers that will be able to implement a recipe, control the machine, and interact with the user ensure that the end user is able to operate the machine easily.

  • Patent number: 11549271
    Abstract: The present disclosure provides an anti-slip floor tile including a base layer, a decorative layer on the base layer, and a wear resistant layer on the decorative layer. The wear resistant layer includes a non-rigid or semi-rigid thermoplastic resin, and a plurality of first mineral particles uniformly distributed inside the thermoplastic resin. The present disclosure can improve the wear resistance of the anti-slip floor tile by dispersing the first mineral particles in the wear resistant layer.
