  • Patent number: 12032672
    Abstract: According to an embodiment of the present application, there is provided an image verification method and apparatus, an electronic device and a computer-readable storage medium, which can be applied to the technical field of network security and the field of image processing and recognition. The image verification method includes: displaying a first image portion and a second image portion, the first image portion being rotatable with respect to the second image portion, the first image portion and the second image portion being obtained by cropping an original image and rotating the cropped first image portion with respect to the second image portion; receiving an operation for rotating the first image portion; rotating the first image portion based on the operation; and determining whether an angle of the first image portion relative to the second image portion matches with the original image, in response to determining that the operation is ended.

  • Patent number: 11950888
    Abstract: A pulse diagnostic device and a system of pulse diagnosis are provided. The pulse diagnostic device includes a cuff and a main monitor. The cuff includes a tube and an air bag arranged with an air path interface. A gas medium is received in the air bag. The tube is connected to the air path interface. The main monitor includes a pressure sensor and a controller. The tube extends to reach the main monitor and is connected to the pressure sensor, and the pressure sensor further connects to the controller. When the pulse diagnostic device is working, the cuff contacts an artery, the pressure sensor senses a pressure of the gas medium in the tube. The pressure sensor transmits the pressure of the gas medium to the controller. The controller obtains the pulse information and the blood pressure information based on the pressure of the gas medium.
