  • 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: 8411932
    Abstract: An example-based 2D to 3D image conversion method, a computer readable medium therefore, and a system are provided. The embodiments are based on an image database with depth information or with which depth information can be generated. With respect to a 2D image to be converted into 3D content, a matched background image is found from the database. In addition, graph-based segmentation and comparison techniques are employed to detect the foreground of the 2D image so that the relative depth map can be generated from the foreground and background information. Therefore, the 3D content can be provided with the 2D image plus the depth information. Thus, users can rapidly obtain the 3D content from the 2D image automatically and the rendering of the 3D content can be achieved.

    Abstract: A control box includes a shell, a display hole, an active member, an indicating member and an interlinking member. The display hole is formed in the shell. The active member has a turn-on end and a turn-off end and is pivotally connected with the shell so as to seesaw. The indicating member is movably disposed in the shell and has a first identifiable portion and a second identifiable portion. The interlinking member is connected between the active member and the indicating member to drive the indicating member to move. Accordingly, when the active member seesaws under the effect of an external force, the indicating member is driven by the interlinking member to show the first identifiable portion or the second identifiable portion in the display hole.
