An image file management method includes receiving a write instruction used to instruct to write a first image file; determining, based on the write instruction, at least one first edge cloud node from a plurality of edge cloud nodes included in an image file management system; and writing a plurality of data blocks included in the first image file into the at least one first edge cloud node, so that each first edge cloud node stores a part or all of the plurality of data blocks included in the first image file.

Image file management utilizing edge cloud nodes

An edge system includes a plurality of first-layer circles and a second-layer circle, and a geographical area represented by the second-layer circle includes a geographical area represented by each first-layer circle, that is, the first-layer circles are deployed in the second-layer circle. Each first-layer circle includes a plurality of sites, the sites include an initial site and are also included in the second-layer circle, and the initial site processes a data operation request sent by a client in a first-layer circle including the initial site, and in the second-layer circle.

Edge system and data operation request processing method

A wake-up desk lamp, comprises a main control unit which is respectively connected with and send control signals to a desk lamp control unit and a wake-up light control unit respectively; the desk lamp control unit is connected to the desk lamp drive unit, and the desk lamp control unit control the desk lamp drive unit according to the control signal to drive a desk lamp emitting module to turn on and off; the wake-up light control unit is connected to the wake-up light drive unit, the wake-up light control unit control the wake-up light drive unit according to the control signal to drive a wake-up light emitting module to turn on and off. The lamp has both lighting function and wake-up function, which saves the area occupied by the lamp and the power consumption, and the user purchases one product to have the effect of two products.

Wake-up desk lamp

A distributed system for creating a consistency snapshot for a distributed application includes a control node and multiple execution nodes including a source execution node, an intermediate execution node, and a leaf execution node. The source execution node receives a snapshot event, and generates a single-point snapshot of an application instance associated with the source execution node. Each of the intermediate execution node and the leaf execution node sequentially receives snapshot events separately sent by two parent nodes of the respective nodes, generates a single-point snapshot of an application instance associated with the respective nodes after receiving the first snapshot event, records a log of a task when executing the task triggered by another parent node different from a parent node sending the first snapshot event, and stops recording a log of a task triggered each time one snapshot event sent by a parent node is received subsequently.

Method for creating consistency snapshot for distributed application, apparatus, and distributed system

A data backup method for a mobile terminal and a mobile terminal including the same. The method includes: receiving a data backup request; backing up information data by blocks and generating backup data of each block; scanning the backup data of each block and generating corresponding statistics information; and storing the backup data and the statistics information of each block.

Data backup and recovery method for mobile terminal and mobile terminal

The present invention provides a switching circuit and an electronic device, which relate to the field of electronic technologies, so as to improve reliability of image processing. The switching circuit includes a comparator circuit, a first switch circuit, a second switch circuit, a first drive voltage source, and a second drive voltage source. Two input ends of the comparator circuit respectively receive an input voltage and a reference voltage, an output end is separately connected to an input end of the first switch circuit and an input end of the second switch circuit; The comparator circuit determines whether the input voltage is greater than the reference voltage, outputs a high level when determining that the input voltage is greater than the reference voltage, and outputs a low level when determining that the input voltage is not greater than the reference voltage.
