Example implementations are described in detail here, and examples of the example implementations are presented in the accompanying drawings. When the following description relates to the accompanying drawings, unless specified otherwise, same numbers in different accompanying drawings represent the same or similar elements. Implementations described in the following example implementations do not represent all implementations consistent with the one or more implementations of the present specification. On the contrary, the implementations are only examples of apparatuses and methods that are described in the appended claims in detail and consistent with some aspects of the one or more implementations of the present specification.
It is worthwhile to note that in other implementations, steps of a corresponding method are not necessarily performed in a sequence shown and described in the present specification. In some other implementations, the method can include more or fewer steps than those described in the present specification. In addition, a single step described in the present specification can be divided into a plurality of steps for description in other implementations, and a plurality of steps described in the present specification can be combined into a single step for description in other implementations.
