Abstract: An object detection method and apparatus include obtaining a point cloud of a scene that includes location information of points. The point cloud is mapped to a 3D voxel representation. A convolution operation is performed on the feature information of the 3D voxel to obtain a convolution feature set and initial positioning information of a candidate object region is determined based on the convolution feature set. A target point is located in the candidate object region in the point cloud is determined and the initial positioning information of the candidate object region is adjusted based on the location information and target convolution feature information of the target point. Positioning information of a target object region is obtained to improve object detection accuracy.

Abstract: The present disclosure provides a Traditional Chinese Medicine inspection device of a composite millimeter-wave radar, and relates to the technical field of Traditional Chinese Medicine detection devices. The Traditional Chinese Medicine inspection device of the composite millimeter-wave radar includes a base, wherein a moving frame is threadedly installed at the top end of the base, a mounting table is slidably installed at the top end of the moving frame, a driving device is installed inside the mounting table, and a connecting frame is rotatably installed at the top end of the mounting table; the driving device has a driving motor and a driving rod, a detection device is rotatably installed at the right end of a connecting arm body, and a transmission device is installed at the bottom end of the connecting arm body.

Abstract: A card connector for receiving a complementary card includes an elongate insulative housing having a first elongate wall, a second elongate wall opposite the first elongate wall and defining a plurality of passageways therein, a slot defined between the first and the second elongate walls and communicating with the passageways, and first and second supporting arms respectively and integrally formed with the two elongate walls and extending substantially perpendicular therefrom. A plurality of contacts are received in the passageways and project into the slot. First and second elastic locking members extend from two distal ends of the first elongate wall and are spaced from the first and second supporting arms for engagement with the complementary card which is inserted into the slot of the housing, wherein the locking members are manually bent outward with respect to an axis therebetween for releasing the engagement between the complementary card and the connector.

Abstract: A pressure absorbing contact includes an engaging portion for fixing in a spaced passageway of a connector. A pressure absorbing portion perpendicularly and obliquely extends from the engaging portion. An elastic curved contacting portion extends from the pressure absorbing portion and includes a contacting surface for electrically contacting an externally inserted contact. A frictional force between the contacting surface of the pressure absorbing contact and the externally inserted contact is considerably eliminated by deformation of the pressure absorbing portion and the elastic curved contacting portion upon application of the frictional force on the contacting surface of the pressure absorbing contact.
