Embodiments of the present application provide an inflation mechanism, a printing device, and a printing system, relating to the field of 3D printing technology. The inflation mechanism includes: an air pump (210); and an air path (230), where one end of the air path (230) is connected to an output end of the air pump (210), and the other end of the air path (230) is configured to communicate with a printing chamber (740) of a printing module.

The present disclosure provides an X-ray imaging apparatus, and a wireless power transfer device thereof. The wireless power transfer device, comprising: a first annular structure (60, 10), on which a first frame (61, 11) is fixed, a first winding (62, 12) being wound around the first frame (61, 11); and a second annular structure (63, 13), on which a second frame (64, 14) is fixed, a second winding (65, 15) being wound around the second frame (64, 14), wherein the first winding (62, 12) and the second winding (65, 15) are disposed facing each other, and the second annular structure (63, 13) is rotatable relative to the first annular structure (60, 10). The present disclosure can enhance the signal transmission performance of the X-ray imaging apparatus.

This disclosure provides an electronic device based on a motorized rotating-shaft assembly, including a first main body, a second main body and a connection mechanism. The first main body and the second main body are connected via the connection mechanism. The second main body includes a first surface and at least one camera arranged on the first surface. The connection mechanism is configured to drive at least one of the second main body or the first main body to rotate, so as to expose or conceal at least part of the first surface. The electronic device based on the motorized rotating-shaft assembly in the present disclosure features high flexibility and convenience.

Embodiments of the present disclosure provide a three-dimensional reconstruction method. Mark points are set on a surface of a target object. Then, multiple frames of mark point three-dimensional point cloud are reconstructed based on image frames containing a mark point pattern, and multiple frames of target object three-dimensional point cloud are reconstructed based on image frames containing a structured light pattern. As a coordinate transformation relationship between the multiple frames of the three-dimensional point cloud can be accurately determined, and a coordinate transformation relationship between a single frame of the mark point three-dimensional point cloud and a single frame of the target object three-dimensional point cloud can also be determined, the mark points can further be used to assist in stitching the multiple frames of the target object three-dimensional point cloud, to obtain a more accurate stitching result.

A method of dynamically determining a readiness score of a user using a wearable device. The method includes detecting, by the wearable device when worn by the user, one or more sensor or physiological signals associated with the user, and determining, by a processor, an estimation of two or more readiness components based on the one or more sensor or physiological signals. The two or more readiness components include a physical energy of the user associated with physical energy consumption of the user, physical energy recovery of the user, or both. The two or more readiness components also include a mental energy of the user associated with mental energy consumption of the user, mental energy recovery of the user, or both. The method further includes determining the readiness score based on the estimation of each of the two or more readiness components.
