Abstract: The present disclosure proposes a method and apparatus for image transmission for three-dimensional (3D) scene reconstruction. A target image may be obtained. A geometry feature and an appearance feature may be disentangled from the target image. An intermediate image may be reconstructed based on the geometry feature and a reference appearance feature. A difference between the intermediate image and the target image may be determined. The geometry feature may be transmitted to a receiving device for 3D scene reconstruction in response to determining that the difference is lower than a predetermined threshold.

Abstract: Disclosed are a multi-pole radio frequency (RF) device, a method for controlling multi-pole RF device, and an RF therapeutic apparatus. The multi-pole RF device includes an RF power supply, a return electrode, a therapeutic electrode, a controller, a first switch switching circuit, and/or a second switch switching circuit. The controller controls the third input terminal and the fourth input terminal of the second switch switching circuit to be switchably connected to the third output terminal and the fourth output terminal. In the unipolar mode, the controller controls the first output terminal and the second output terminal to be electrically connected to the therapeutic electrode and the return electrode respectively. In the bipolar mode, the controller controls the first output terminal and the second output terminal to be connected to at least one of the plurality of electrode slices respectively.

Abstract: A method for constructing a multistage network includes: deploying a plurality of nodes; constructing the upper network with at least one node of the plurality of nodes; and in response to determining there is an isolated node, determining an intermediate node for the isolated node and adding the isolated node into the upper network or one of the at least one sub-network according to the intermediate node.

Abstract: Disclosed are a microneedle therapy control method and a microneedle therapy control device, and a radio-frequency (RF) microneedle therapy instrument. The microneedle therapy control method comprises the following steps: acquiring a piercing depth of a microneedle electrode; determining, according to the piercing depth of the microneedle electrode, a movement interval of the microneedle electrode in a length direction; sending a first control signal to a linear driver, so as to enable the linear driver to drive the microneedle electrode to move at a preset speed along the length direction within the movement interval; and sending a second control signal to a power module, so as to enable the power module to provide RF energy to the microneedle electrode during the movement of the microneedle electrode in the movement interval.
