  • Publication number: 20210226386
    Abstract: A contact module, a female connector and a male connector, wherein the female contact unit of the female connector includes signal contacts arranged in pairs and ground contacts arranged corresponding to the signal contacts arranged in pairs. A side surface of each signal contact facing the corresponding ground contact includes a signal contact portion in conductive contact with the signal contact portion of an adapter connector. A side surface of each ground contact facing the corresponding signal contact includes a shielding contact portion in electrical contact with the ground contact of the adapter connector. A plugging space for plugging the contact module of the adapter connector is between the signal contacts and the ground contacts. The female connector enables the adapted contact unit to be clamped between the corresponding signal contact and the corresponding ground contact to realize corresponding conduction.

  • Patent number: 10818011
    Abstract: The present application relates to the technical field of image recognition, and provides a carpal segmentation and recognition method, including: performing threshold segmentation on a carpal region of interest on a child orthotopic wrist X-ray image based on an adaptive threshold segmentation manner of variable threshold segmentation windows, and extracting edge information of the carpal region of interest based on an edge detection manner; combining a binarized image obtained by performing the threshold segmentation with the extracted edge information to obtain an initial segmentation image; performing carpal recognition on the initial segmentation image by using a carpal anatomy priori model to obtain an initial recognition image including information of each carpal bone; and performing boundary optimization on the initial recognition image, and outputting a carpal recognition image obtained after the boundary optimization is performed.
