  • Patent number: 11406342
    Abstract: A device and a method for post-processing of computed tomography (CT), which are adapted to improve an identification image of a focal nodular hyperplasia (FNH) of a liver, are provided. The method includes: obtaining the identification image including a liver region and a non-liver region and a Hounsfield unit (HU) value of each pixel corresponding the identification image, wherein the liver region includes an FNH candidate region; calculating an average HU of the liver region; adjusting an HU value of the non-liver region to the average HU value of the liver region with respect to the identification image to generate a processed identification image; and updating the FNH candidate region according to a morphological algorithm based on the processed identification image to generate an updated FNH candidate region.

  • Patent number: 11217786
    Abstract: An aqueous lithium-ion battery and an electrode used therein are provided, wherein the electrode includes a current collector, a coating layer, and a composite layer. The coating layer is disposed on at least one surface of the current collector, and the coating layer contains an active material. The composite layer is disposed on a surface of the coating layer. The composite layer includes a first film and a second film, wherein the first film is between the second film and the surface of the coating layer, and the water contact angle of the first film is greater than the water contact angle of the second film.

    Abstract: A device and a method for post-processing of computed tomography (CT), which are adapted to improve an identification image of a focal nodular hyperplasia (FNH) of a liver, are provided. The method includes: obtaining the identification image including a liver contour and a non-liver contour and a Hounsfield unit (HU) value of each pixel corresponding the identification image, wherein the liver contour includes an FNH candidate contour; calculating an average HU of the liver contour; adjusting an HU value of the non-liver contour to the average HU value of the liver contour in respect with the identification image to generate a processed identification image; and updating the FNH candidate contour according to a morphological algorithm based on the processed identification image to generate an updated FNH candidate contour.

  • Patent number: 10948544
    Abstract: A battery safety identifying method is provided. The method includes the following steps. A voltage drop and a voltage drop rate are detected when a battery is abnormal. A duration time of the voltage drop and a voltage recovery ratio are detected when the battery is abnormal. A surface temperature or a temperature rise rate is detected when the battery is abnormal. A plurality of hazard levels of battery abnormality and at least one protection mechanism are set according to the voltage drop, the voltage drop rate, the voltage recovery ratio and the surface temperature or the temperature rise rate.
