  • Patent number: 10759912
    Abstract: Provided are a superabsorbent polymer and a preparation method thereof. The superabsorbent polymer may effectively avoid a rewetting phenomenon after absorbing liquid, because a saline solution hardly remains in the empty spaces between swollen gel particles. Accordingly, the superabsorbent polymer may be used to provide hygienic materials, such as diapers, sanitary napkins, etc., which have a fluffy texture even after body fluid is discharged thereto.

  • Patent number: 10632298
    Abstract: Systems and methods are disclosed for controlling the flow of fluids in a fluid infusion system. The system may include first and second fluid containers, first and second tubes coupled to the first and second fluid containers, and an external valve coupled to the second tube and configured to be attached to the first tube. The valve may be configured to shape the first tube to form a valve region which is opened or closed by an actuating element in the valve that is driven by hydrostatic pressure from the second tube. A full second container may generate a pressure that is concentrated through a diaphragm onto a pin which presses on the shaped first tube region, closing it to allow only fluid from the second container to flow. When the fluid level in the second line falls reducing pressure, the pin's force reduces until the first tube is opened.

  • Patent number: 10372563
    Abstract: Disclosed are an analyzing system for managing an information storage table and a control method thereof. That is, each of the physical basic regions, which are units of hashing an information storage position, is divided into a plurality of physical sub regions having same size. Then, a combination of virtual basic regions which satisfy a predetermined target value is checked from all configurable combinations and a hash value related with the combination of the virtual basic regions which satisfies the checked target value is stored in a predetermined region of a memory. Therefore, even though an information storage space required for every unit region is overloaded, when there is an extra information storage space in another region, the information storage space having an extra space is used to maximize efficiency of the information storage space.
