For example, the embodiment is an integrated circuit configuration such as memory, processing, logic, a look-up table, etc., capable of executing various functions by controlling one or more microprocessors or other control devices Can be hired. Similar to how the components of the present invention can be implemented with software programming or software elements, embodiments include various algorithms implemented with a combination of data structures, processes, routines or other programming components, including C, C++. , Java, assembler, or the like may be implemented in a programming or scripting language. Functional aspects can be implemented with an algorithm running on one or more processors. In addition, the embodiments may employ conventional techniques for electronic environment setting, signal processing, and/or data processing. Terms such as “mechanism”, “element”, “means”, and “composition” can be used widely, and are not limited to mechanical and physical configurations. The term may include the meaning of a series of routines of software in connection with a processor or the like.

Specific implementations described in the embodiments are examples, and do not limit the scope of the embodiments in any way. For brevity of the specification, descriptions of conventional electronic configurations, control systems, software, and other functional aspects of the systems may be omitted. In addition, the connection or connection members of the lines between the components shown in the drawings exemplarily represent functional connections and/or physical or circuit connections. Connections, or circuit connections, may be represented. In addition, if there is no specific mention such as “essential” or “importantly”, it may not be an essential component for the application of the present invention.

In the specification of the embodiment (especially in the claims), the use of the term "above" and a similar term may correspond to both the singular and the plural. In addition, when a range is described in an embodiment, the invention to which individual values falling within the range are applied (unless otherwise stated), it is the same as describing each individual value constituting the range in the detailed description. . Finally, if there is no clearly stated or contrary to the order of steps constituting the method according to the embodiment, the steps may be performed in an appropriate order. The embodiments are not necessarily limited according to the order of description of the steps. The use of all examples or illustrative terms (for example, etc.) in the embodiments is merely for describing the embodiments in detail, and the scope of the embodiments is limited by the above examples or illustrative terms, unless limited by the claims. It is not. In addition, those skilled in the art can recognize that various modifications, combinations, and changes may be configured according to design conditions and factors within the scope of the appended claims or their equivalents.
