Detailed Description

In order to make the objects, technical solutions and advantages of the present application clearer, the technical solutions of the embodiments of the present application will be clearly and completely described below with reference to the drawings of the embodiments of the present application. It should be apparent that the described embodiments are only some of the embodiments of the present application, and not all embodiments. All other embodiments, which can be derived by a person skilled in the art from the described embodiments of the application without any inventive step, are within the scope of protection of the application. It will be understood that some of the technical means of the various embodiments described herein may be replaced or combined with each other without conflict.

In the description of the present application and claims, the terms "first," "second," and the like, if any, are used solely to distinguish one from another as between described objects and not necessarily in any sequential or technical sense. Thus, an object defined as "first," "second," etc. may explicitly or implicitly include one or more of the object. Also, the use of the terms "a" or "an" and the like, do not denote a limitation of quantity, but rather denote the presence of at least one of the two, and "a plurality" denotes no less than two.

In the description of the present application and the claims, the terms "connected," "mounted," "fixed," "housed," and the like are used broadly unless otherwise indicated. For example, "connected" may be a separate connection or may be integrally connected; can be directly connected or indirectly connected through an intermediate medium; may be non-detachably connected or may be detachably connected. For example, "accommodated" does not necessarily mean that the entire body is completely accommodated, and the concept also includes a partial accommodation case in which a part protrudes outward. The specific meaning of the foregoing terms in the present application can be understood by those skilled in the art as appropriate.

In the description of the present application and in the claims, if there is an orientation or positional relationship indicated by the terms "upper", "lower", "horizontal", etc. based on the orientation or positional relationship shown in the drawings, it is only for the convenience of clearly and simply describing the present application, and it is not indicated or implied that the elements referred to must have a specific direction, be constructed and operated in a specific orientation, and these directional terms are relative concepts for the sake of description and clarification and may be changed accordingly according to the change of orientation in which the elements in the drawings are placed. For example, if the device in the figures is turned over, elements described as "below" other elements would then be oriented "above" the other elements.

In the description of the present application and in the claims, the presence of the terms "in sequence" and "sequentially", for example the phrase "A, B, C arranged in sequence", merely indicates the order of arrangement of the elements A, B, C and does not exclude the possibility of arranging other elements between a and B and/or between B and C.

In the description of the present specification and claims, the terms "laminated" and "lamination", if any, include not only a case where they are laminated (or laminated) in contact with each other but also a case where they are laminated (or laminated) with another layer interposed therebetween.

In the description of the specification and claims, the terms "based on" and "based on," if any, are used to describe one or more factors that affect the determination. The term does not exclude additional factors that influence the determination. That is, the determination may be based solely on these factors or at least partially on these factors. For example, the phrase "determine B based on a," in which case a is a factor that affects the determination of B, does not exclude that the determination of B may also be based on C.

In the description of the specification and claims of this application, the term "responsive to" and related terms mean that one signal or event is affected to some extent by another signal or event, but not necessarily completely or directly. If event A occurs "in response" to event B, A may respond directly or indirectly to B. For example, the occurrence of B may ultimately lead to the occurrence of a, but other intermediate events and/or conditions may exist. In other cases, B may not necessarily result in the occurrence of a, and a may occur even though B has not yet occurred. Furthermore, the term "responsive to" may also mean "at least partially responsive to".

In the description of the present specification and claims, the term "if present may generally be interchangeable with" when … "or" at … "or" in response to a determination "or" in response to a detection ", depending on the context.

In the description of the specification and claims of this application, the term "configured to" if present is generally interchangeable with "… capable", "designed to", "for", or "capable", depending on the context.

In the description of the present specification and claims, if there is "direction" with respect to motion, including motion having a directional component, the term "in direction" is not necessarily to be construed as motion in only that one direction, and those skilled in the art will understand the specific meaning of the aforementioned terms in the present application as the case may be.
