wireless communicator 32W, thecontroller 32C, themode switch 32S, and theindicator 32D have substantially the same structures as those of thewireless communicator 20W, thecontroller 20C, themode switch 20S, and theindicator 20D. Thecircuit board 32B, theprocessor 32P, and thememory 32M have the same structures as those of thecircuit board 20B, theprocessor 20P, and thememory 20M of thewireless communication device 20. Thesignal generating circuit 32G, thesignal transmitting circuit 32T, thesignal receiving circuit 32R, and theantenna 32A have substantially the same structures as those of thesignal generating circuit 20G, thesignal transmitting circuit 20T, thesignal receiving circuit 20R, and theantenna 20A of thewireless communication device 20. Thewireless communicator 32W has the first communication mode, the second communication mode, and the third communication mode. Thewireless communicator 32W has substantially the same structure as that of thewireless communicator 20W of thewireless communication device 20. Thus, it will not be described in detail here for the sake of brevity. - An
operating system 210 including a wireless communication device 220 in accordance with a second embodiment will be described below referring toFIGS. 17 and 18 . Theoperating system 210 has the same structure and/or configuration as those of theoperating system 10 except for themode switch 20S. Thus, elements having substantially the same structure and/or configuration as those in the first embodiment will be numbered the same here and will not be described and/or illustrated again in detail here for the sake of brevity. - As seen in
FIG. 17 , in the wireless communication device 220, thecontroller 20C does not user the user input UW1 to set the communication mode of thewireless communicator 20W. In this embodiment, thecontroller 20C includes amemory 220M configured to store mode information MD indicating a selected communication mode. Thecontroller 20C is configured to set thewireless communicator 20W with the selected communication mode based on the mode information MD. The selected communication mode includes one of the first communication mode and the second communication mode. In this embodiment, the selected communication mode includes one of the first communication mode CM1, the second communication mode CM2, and the third communication mode CM3. - The
controller 20C is configured to receive a mode command MC indicating the selected communication mode from aninput device 229. Thecontroller 20C is configured to store the mode command MC as the mode information MD in thememory 220M if thecontroller 20C receives the mode command MC. - Examples of the
input device 229 includes the additionalelectric devices electric devices wireless communicator 20W. Specifically, the user can select the communication mode among the first to third communication modes on thedisplay electric devices electric devices - As seen in
FIG. 18 , thecontroller 20C sets thewireless communicator 20W with the first communication mode CM1 (Step S21). Thecontroller 20C determines the mode information MD (Step S22). Thecontroller 20C sets thewireless communicator 20W with the first communication mode CM1 if the mode information MD indicates the first communication mode CM1 (Steps S21 and S22). Thecontroller 20C sets thewireless communicator 20W with the second communication mode CM2 if the mode information MD indicates the second communication mode CM2 (Steps S21 and S23). The process returns to Step S22. Thecontroller 20C sets thewireless communicator 20W with the third communication mode CM3 if the mode information MD indicates the third communication mode CM3 (Steps S21 and S24). The process returns to Step S22. - The term “comprising” and its derivatives, as used herein, are intended to be open ended terms that specify the presence of the stated features, elements, components, groups, integers, and/or steps, but do not exclude the presence of other unstated features, elements, components, groups, integers and/or steps. This concept also applies to words of similar meaning, for example, the terms “have,” “include” and their derivatives.
- The terms “member,” “section,” “portion,” “part,” “element,” “body” and “structure” when used in the singular can have the dual meaning of a single part or a plurality of parts.
- The ordinal numbers such as “first” and “second” recited in the present application are merely identifiers, but do not have any other meanings, for example, a particular order and the like. Moreover, for example, the term “first element” itself does not imply an existence of “second element,” and the term “second element” itself does not imply an existence of “first element.”
- The term “pair of,” as used herein, can encompass the configuration in which the pair of elements have different shapes or structures from each other in addition to the configuration in which the pair of elements have the same shapes or structures as each other.
- The terms “a” (or “an”), “one or more” and “at least one” can be used interchangeably herein.
- Finally, terms of degree such as “substantially,” “about” and “approximately” as used herein mean a reasonable amount of deviation of the modified term such that the end result is not significantly changed. All of numerical values described in the present application can be construed as including the terms such as “substantially,” “about” and “approximately.”
- The phrase “at least one of” as used in this disclosure means “one or more” of a desired choice. For one example, the phrase “at least one of” as used in this disclosure means “only one single choice” or “both of two choices” if the number of its choices is two. For other example, the phrase “at least one of” as used in this disclosure means “only one single choice” or “any combination of equal to or more than two choices” if the number of its choices is equal to or more than three. For instance, the phrase “at least one of A and B” encompasses (1) A alone, (2), B alone, and (3) both A and B. The phrase “at least one of A, B, and C” encompasses (1) A alone, (2), B alone, (3) C alone, (4) both A and B, (5) both B and C, (6) both A and C, and (7) all A, B, and C. In other words, the phrase “at least one of A and B” does not mean “at least one of A and at least one of B” in this disclosure.
- Obviously, numerous modifications and variations of the present invention are possible in light of the above teachings. It is therefore to be understood that within the scope of the appended claims, the invention may be practiced otherwise than as specifically described herein.
