Abstract: A display method is applied to a display apparatus including a display panel, a display driver chip, and a microprocessor. The display method includes outputting, by the display panel, a scanning-done signal of a first frame image generated after scanning rows of pixel circuits of the display panel; after the microprocessor or the display driver chip receives the scanning-done signal, writing, by the display driver chip, initial data of a second frame image provided by the microprocessor and outputting, by the display driver chip, display data of the second frame image to the display panel based on the initial data; or outputting, by the display driver chip, the display data of the second frame image to the display panel in response to the scanning-done signal, the display data being generated based on the initial data provided by the microprocessor. The second frame image follows the first frame image.

Abstract: Computer-implemented methods, apparatuses and systems for obtaining data authorization are described. In an example method, a first computing node in a trusted computing center receives an authentication request from a first provider. Authentication information is returned to the first provider, where the authentication information comprises a first code hash of a first computing logic running in the first computing node. A channel establishment request sent by the first provider is received after determining that the first computing node passes trusted authentication and the first code hash passes correctness verification. A first trusted channel is established between the first provider and the first computing node according to the channel establishment request. A target encryption key is received through the first trusted channel, thereby authorization to perform computation on a target encrypted shard corresponding to the target encryption key based on the first computing logic is obtained.

Abstract: A data backup method of a distributed file system is provided. The method is based on a comparison of a source file system and a target file system. Metadata of the target file system is compared with metadata of the source file system. The method includes: synchronizing target metadata of a target file according to source metadata of a source file, generating a file checksum list; determining whether a first target block is consistent with a first source block, obtaining and sending a first updated file checksum list to a first data node; determining whether a first chunk is consistent with a first target chunk, generating a first difference list, sending the first difference list and the first updated file checksum list to a first corresponding target data node; creating a temporary block, writing data in the temporary block, replacing the first corresponding target block with the temporary block.

Abstract: A method for vertically grounding and leading down form a center of a composite pole tower includes the following steps: extending a ground down-leading wire from a center of a ground wire cross arm which is made of metal and is positioned on top of the pole tower, wherein the ground down-leading wire is vertically leaded down to the earth form the center of the composite pole tower, wherein when an lower portion of the tower body is a metal pipe, the ground down-leading wire is extended from the center of the composite material and is directly connected to the metal pipe. The method utilizes the advantage of the insulating intensity of the wall of the composite pole tower and enhances the insulating intensity of the transmission line on impact of lightning. The ground down-leading wires are prevented from short-circuiting with the tower body of the composite pole tower, so that advantage of the insulating property of the composite material of the pole towers is realized.
