  • Patent number: 11494663
    Abstract: The present disclosure relates to systems and methods for generating a document based on a template document. The system may perform the methods to crawl across a multi-level tree along a path from a root to a plurality of leaf nodes. The multi-level tree may include a plurality of intermediate level nodes, wherein each of the plurality of intermediate level nodes may be associated with one or more sub-nodes at a next level. Each of the plurality of intermediate level nodes may include an intermediate subject of the intermediate level node, a semantically incomplete intermediate description related to the intermediate subject, and template data defining a position that the intermediate description may be in a corresponding template document.

  • Patent number: 11326766
    Abstract: An LED light with a shift switch related to the technical field of LED lights includes a diffuser, a light body, and a light head sequentially connected from top to bottom. A driving power board and an LED light source board are provided in the light body. A position hole is provided on a side wall of the light body. The driving power board is provided with the shift switch, and the shift switch is provided with a shift handle which passes through the position hole. According to the present application, the effects of reducing the difficulty of modification and replacement and improving the convenience of using the LED light are achieved by controlling the color temperature, the timing or the light intensity of the LED light by multiple positions of the shift switch.

  • Publication number: 20120280717
    Abstract: A method for arc detection includes detecting a changing rate of a signal indicative of light strength, detecting the amplitude of the signal, and indicating an occurrence of an arc if the changing rate of the signal exceeds a first predetermined threshold and the amplitude of the signal exceeds a second predetermined threshold. An arc detecting device, an arc detecting system, and an arc protecting apparatus thereof are provided. The arc detecting system includes a light collector (101) for collecting light, a light converter (103) coupled to the light collector (101) for converting the collected light into an electric signal, and an arc detecting device (106) coupled to the light converter (103) for detecting the occurrence of the arc.
