Thus, a machine-readable medium includes any type of machine-readable medium suitable for storing or transmitting electronic instructions or information in a form readable by a machine (eg, a computer).

In the drawings, some structural or methodological features may be shown in a particular arrangement and/or order. However, it should be understood that such specific arrangements and/or orderings may not be required. Rather, in some embodiments, these features may be arranged in a different manner and/or order than shown in the illustrative figures. Additionally, the inclusion of structural or methodological features in a particular figure does not imply that such features are required in all embodiments, and in some embodiments these features may not be included or may be combined with other features.

It should be noted that each unit/module mentioned in each device embodiment of this application is a logical unit/module. Physically, a logical unit/module can be a physical unit/module, or a physical unit/module. A part of the module can also be realized with a combination of multiple physical units/modules, the physical implementation of these logical units/modules is not the most important, the combination of functions realized by these logical units/modules is the solution The key to the technical issues raised. In addition, in order to highlight the innovative part of this application, the above-mentioned device embodiments of this application do not introduce units/modules that are not closely related to solving the technical problems proposed by this application, which does not mean that the above-mentioned device embodiments do not exist other units/modules.

It should be noted that in the examples and descriptions of this patent, relative terms such as first and second are only used to distinguish one entity or operation from another entity or operation, and do not necessarily require or imply There is no such actual relationship or order between these entities or operations. Furthermore, the term "comprises", "comprises" or any other variation thereof is intended to cover a non-exclusive inclusion such that a process, method, article, or apparatus comprising a set of elements includes not only those elements, but also includes elements not expressly listed. other elements of or also include elements inherent in such a process, method, article, or device. Without further limitations, an element defined by the statement "comprising a" does not exclude the presence of additional identical elements in the process, method, article or apparatus comprising said element.

Although this application has been shown and described with reference to certain preferred embodiments thereof, those skilled in the art will understand that various changes in form and details may be made therein without departing from this disclosure. The spirit and scope of the application.
