  • Publication number: 20250178012
    Abstract: A portable coating device for applying a coating solution onto a solar panel includes a supply module for supplying the coating solution, a base, a spraying module disposed on the base, a transmission module disposed at two opposite ends of the base, an arc bracket, and an applicator. The base spans the solar panel and moves thereon through the support of the transmission module. The arc bracket is disposed at the bottom of the base and has a plurality of seepage openings, and an inner surface of the arc bracket faces the spraying module. The applicator includes a porous material that deforms under pressure. The applicator is assembled to the base and supported by the arc bracket.

  • Publication number: 20250172648
    Abstract: A calibration method of the magnetic field model and a controller for electromagnetic positioning are provided. In the method, a magnetic field is established through a magnetic field transmitter; measurement data is obtained through a magnetic field sensor, where the measurement data includes the amplitude of induced voltage at multiple measurement positions in the magnetic field; and the magnetic field model is corrected according to the error between the measurement data and simulated data correction, where the magnetic field model is used to generate simulation data corresponding to multiple measurement locations. The steps of modifying the magnetic field model include: establishing one or more objective functions through the nonlinear least squares method based on the error between the measured data and the simulated data; and determining the modified magnetic field model based on one or more solutions of the objective function. Therefore, positioning accuracy can be improved.

  • Publication number: 20240404242
    Abstract: An operation method performed by an image processor is provided, including the following operations: receiving a mixed image including an input image and a first on-screen-display (OSD) pattern; generating a second OSD pattern, different from the first OSD pattern, based on the mixed image. The second OSD pattern encompasses protection regions of the input image, and the protection regions are in close proximity of the first OSD pattern. The method further includes operations of performing image processing to remaining regions, different from the protection regions, of the input image and generating an output image. The output image includes the second OSD pattern and the remaining regions of the input image, being performed by the image processing.
