The shapes, dimensions, ratios, angles, and numbers disclosed for describing aspects of the present specification and claims are merely examples, and thus, the present specification and claims are not limited to the details shown. In the following description, a detailed description of related known functions or configurations will be omitted when it may be determined that the emphasis of the present specification and claims is unnecessarily obscured.
The foregoing description of the embodiments and specific examples of the present application has been presented for purposes of illustration and description; this is not the only form of practicing or implementing the application as embodied. The description covers the features of the embodiments and the method steps and sequences for constructing and operating the embodiments. However, other embodiments may be utilized to achieve the same or equivalent functions and sequences of steps.
In the foregoing detailed description, various features are grouped together in a single embodiment for the purpose of streamlining the disclosure. This method of disclosure is not to be interpreted as reflecting an intention that the claimed embodiments of the subject matter require more features than are expressly recited in each claim. Rather, as the following claims reflect, application lies in less than all features of a single disclosed embodiment. Thus the following claims are hereby expressly incorporated into this detailed description, with each claim standing on its own as a separate preferred embodiment of this application.
The previous description of the disclosed embodiments is provided to enable any person skilled in the art to make or use the present application. As will be apparent to those skilled in the art; various modifications to these embodiments will be readily apparent, and the generic principles defined herein may be applied to other embodiments without departing from the spirit or scope of the disclosure. Thus, the present disclosure is not intended to be limited to the embodiments shown herein but is to be accorded the widest scope consistent with the principles and novel features disclosed herein.
The foregoing description includes examples of one or more embodiments. It is, of course, not possible to describe every conceivable combination of components or methodologies for purposes of describing the aforementioned embodiments, but one of ordinary skill in the art may recognize that many further combinations and permutations of various embodiments are possible. Accordingly, the embodiments described herein are intended to embrace all such alterations, modifications and variations that fall within the scope of the appended claims. Furthermore, as used in the specification or claims, the term "comprising" is intended to be inclusive in a manner similar to the term "comprising," as interpreted when employed as a transitional word in a claim. Furthermore, any use of the term "or" in the specification of the claims is intended to mean "non-exclusive or".
It should be noted that although the terms "first," "second," "top," "bottom," "one side," "another side," "one end," "the other end," etc. may be used and used in this specification to describe various components, these components and portions should not be limited by these terms. These terms are only used to distinguish one element from another element. For example, a first element could be termed a second element, and, similarly, a second element could be termed a first element, with top and bottom elements, under certain circumstances, also being interchangeable or convertible with one another; the components at one end and the other end may be the same or different in performance from each other.
In addition, when constituting the components, although not explicitly described, it is understood that a certain error region is necessarily included.
