The processor WC11 is configured to control the signal transmitting circuit WC15 to generate a wireless signal SG1 via the antenna WC17 in response to the signal SG1 of the electrical switch unit SW1. In this embodiment, the signal transmitting circuit WC15 can encrypt control information (e.g., shift information or unique identifying information) to generate encrypted wireless signals SG1. The signal transmitting circuit WC15 encrypts digital signals stored in the memory WC12 using a cryptographic key. The signal transmitting circuit WC15 transmits the encrypted wireless signals SG1. Thus, the wireless communicator WC1 wirelessly transmits the signal SG1 to the operating device 7 when the user operates the electrical switch unit SW1.
Further, the processor WC11 is configured to control the signal receiving circuit WC16 to receive a wireless signal from the operating device 7 via the antenna WC17. In this embodiment, the signal receiving circuit WC16 decodes the wireless signal to recognize information (e.g., unique identifying information) wirelessly transmitted from the operating device 7. The signal receiving circuit WC16 may decrypt the encrypted wireless signal using the cryptographic key. Namely, the wireless communicator WC1 is configured to transmit a wireless signal to the operating device 7 and to receive a wireless signal to recognize information from the operating device 7.

The above embodiments and the above modifications can be at least party combined with each other if needed and/or desired.
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.”
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.
The present application is a continuation-in-part application of the U.S. patent application Ser. No. 15/983,099 filed May 18, 2018. The contents of this application are incorporated herein by reference in their entirety.
