  • Patent number: 11937932
    Abstract: An acute kidney injury predicting system and a method thereof are proposed. A processor reads the data to be tested, the detection data, the machine learning algorithm and the risk probability comparison table from a main memory. The processor trains the detection data according to the machine learning algorithm to generate an acute kidney injury prediction model, and inputs the data to be tested into the acute kidney injury prediction model to generate an acute kidney injury characteristic risk probability and a data sequence table. The data sequence table lists the data to be tested in sequence according to a proportion of each of the data to be tested in the acute kidney injury characteristics. The processor selects one of the medical treatment data from the risk probability comparison table according to the acute kidney injury characteristic risk probability.

  • Patent number: 11779829
    Abstract: A skateboard includes a deck, at least a front wheel set and a rear wheel set. The front wheel set, which is arranged at a bottom of the deck at a position close to a front end thereof, includes at least one rigid and rotatable front wheel frame and at least two front wheels. The rear wheel set, which is arranged at a bottom of the deck at a position close to the rear end thereof, includes at least one rigid and non-rotatable rear wheel frame and at least two rear wheels. The outer side of the wheel is circular or arc-shaped. The structure of the skateboard allows the user to change a center of gravity and to lift the sides of the board with foot, so as to only rely on the outer arc of the left or right front and rear wheels to slide, while the rotatable front wheel frame in the left or right side may still be utilized for rotating in the forward direction, which allows a skateboard experience of forward or changing the travelling direction.
