  • Publication number: 20240295941
    Abstract: Disclosed are a method and an apparatus of screen saver interaction, an electronic device, and a storage medium. In an embodiment, a screen saver interface may be displayed. Upon receiving the interaction trigger instruction from the interaction object for the screen saver content in the screen saver interface, target interaction information is obtained based on the interaction trigger instruction. A dynamic interaction effect for the screen saver content is determined based on the target interaction information. The dynamic interaction effect for the screen saver content is displayed on the screen saver interface to realize dynamic interaction between the interaction object and the screen saver content.

  • Patent number: 11145035
    Abstract: The present invention proposes a method for rapidly dehazing an underground pipeline image based on dark channel prior (DCP). The method includes: preprocessing a hazy underground pipeline image to obtain a dark channel image corresponding to the hazy image; average-filtering the obtained dark channel image to estimate an image transmittance; compensating an offset value for an average filtering result to obtain a rough estimate of the transmittance; using a pixel value of the original image and an average-filtered image to estimate a global atmospheric light value; and using a physical restoration model to restore a dehazed image. The method of the present invention realizes the timeliness of the algorithm while ensuring the dehazing effect, and is suitable for scientific fields such as video monitoring of underground pipeline environment and identification of underground pipeline defects.

  • Patent number: 8257840
    Abstract: The present invention provides a security functional thin film and a security product containing such a thin film. The security functional thin film is of an amorphous structure, and possesses soft magnetic characteristics. Large Barkhausen effect can be detected along the in-plane preferred direction of magnetization; and the Large Barkhausen effect significantly attenuates, or no such signal can be detected, in a direction perpendicular to the in-plane preferred direction of magnetization. The thin film has a thickness of 20-300 nm, and the thin film also possesses element encoding characteristics that can be authenticated by experts. The security functional thin film of the present invention can be fabricated by magnetron sputtering web coating process.

  • Patent number: 7615788
    Abstract: A device and method of forming electronics and microelectromechanical on a silicon carbide substrate having a slow etch rate is performed by forming circuitry on the substrate. A protective layer is formed over the circuitry having a slower etch rate than the etch rate of the silicon carbide substrate. Microelectromechanical structures supported by the substrate are then formed. The circuitry comprises a field effect transistor in one embodiment, and the protective layer comprises a heavy metal layer.
