Another mode may be provided between the first communication mode and the second communication mode, between the second communication mode and the third communication mode, and / or between the third communication mode and the first communication mode.

[0108] like Figure 2As shown, in this embodiment, the wireless communication device 20 further includes a mode switcher 20S configured to receive a user input UW1. The controller 20C is configured to set the wireless communicator 20W to one of the first communication mode and the second communication mode based on the user input UW1. In this embodiment, the controller 20C is configured to set the wireless communicator 20W to one of the first communication mode and the second communication mode if the mode switcher 20S receives the user input UW1. For example, the mode switcher 20S includes a momentary switch. However, the structure of the mode switcher 20S is not limited to the momentary switch. The controller 20C can be configured to automatically set the wireless communicator 20W to one of the first communication mode and the second communication mode based on information other than the user input UW1. For example, the controller 20C can be configured to automatically set the wireless communicator 20W to one of the first communication mode and the second communication mode based on information related to the remaining battery power.

[0109] The controller 20C is configured to change the mode of the wireless communicator 20W among the first communication mode, the second communication mode, and the third communication mode in a predetermined order based on the user input UW1 received by the mode switcher 20S. The controller 20C is configured to change the mode of the wireless communicator 20W from the first communication mode to the second communication mode if the mode switcher 20S receives the user input UW1 in the first communication mode.

The controller 20C is configured to change the mode of the wireless communicator 20W from the third communication mode to the first communication mode if the mode switcher 20S receives the user input UW1 in the third communication mode.

[0110] The mode switcher 20S is configured to receive an additional user input UW2 different from the user input UW1. In this embodiment, an example of the user input UW1 includes a short press or a regular press of the mode switcher 20S. An example of the additional user input UW2 includes a long press of the mode switcher 20S. However, the user input UW1 and the additional user input UW2 are not limited to this embodiment.

[0111] Wireless communication device 20 also includes an indicator 20D configured to indicate a first communication mode and a second communication mode. In this embodiment, indicator 20D is configured to indicate the first communication mode, the second communication mode, and the third communication mode differently. Controller 20C is configured to control indicator 20D to indicate the first communication mode in a first manner if wireless communicator 20W is in the first communication mode. Controller 20C is configured to control indicator 20D to indicate the second communication mode in a second manner if wireless communicator 20W is in the second communication mode. Controller 20C is configured to control indicator 20D to indicate the third communication mode in a third manner if wireless communicator 20W is in the third communication mode.

[0112] In this embodiment, the indicator 20D includes a light emitting device having a light emitting diode (LED). The indicator 20D is configured to emit each of a first light having a first color and a second light having a second color different from the first color. A first mode includes alternately turning on the first light and the second light. A second mode includes causing the first light to flash twice in a row and causing the second light to flash once. A third mode includes causing the first light to flash three times in a row and causing the second light to flash once. However, the first to third modes are not limited to this embodiment.

The indicator 20D can include a display to display information related to the first to third communication modes.

[0113] Wireless communicator 20W has an awake state and a sleep state. In the awake state, wireless communicator 20W is configured to wirelessly transmit communication signals by selectively using at least one of a first communication protocol CP1 and a second communication protocol CP2 different from first communication protocol CP1. In the sleep state, wireless communicator 20W is configured to stop transmitting communication signals. Controller 20C is configured to set wireless communicator 20W to one of the awake state and the sleep state.

[0114] like Figure 6 to Figure 8 As shown, wireless communicator 20W is configured to be in each of the first to third modes when wireless communicator 20W is in the awake state. Controller 20C is configured to store the current communication mode in memory 20M. Controller 20C is configured to set wireless communicator 20W to the current communication mode stored in memory 20M if controller 20C changes the state of wireless communicator 20W from the sleep state to the awake state.

[0115] In the awake state, wireless communicator 20W is configured to wirelessly transmit communication signals by selectively using at least one of the first communication protocol CP1 and the second communication protocol CP2. In the first communication mode, wireless communicator 20W operates at a first power consumption. In the second communication mode, wireless communicator 20W operates at a second power consumption. In the third communication mode, wireless communicator 20W operates at a third power consumption. The second power consumption is lower than the first and third power consumptions. The third power consumption is lower than the first power consumption. In the sleep state, wireless communicator 20W operates at a sleep state power consumption. The sleep state power consumption is lower than the first, second, and third power consumptions.

[0116] like Figure 9 As shown, if the wireless communication device 20 is turned on, the controller 20C sets the wireless communicator 20W to the first communication mode (step S1). The controller 20C determines whether the mode switch 20S receives user input UW1 in the first communication mode (step S2). If the mode switch 20S receives user input UW1 in the first communication mode, the controller 20C sets the wireless communicator 20W to the second communication mode (steps S2 and S3). The controller 20C determines whether the mode switch 20S receives user input UW1 in the second communication mode (step S4). If the mode switch 20S receives user input UW1 in the second communication mode, the controller 20C sets the wireless communicator 20W to the third communication mode (steps S4 and S5). The controller 20C determines whether the mode switch 20S receives user input UW1 in the third communication mode (step S6). If the mode switch 20S receives user input UW1 in the third communication mode, the program returns to step S1 (step S6). That is, if mode switcher 20S receives user input UW1 in the third communication mode, controller 20C sets wireless communicator 20W to the first communication mode (steps S1 and S6).

[0117] like Figure 10 to Figure 12 As shown, controller 20C is configured to control wireless communicator 20W based on the second communication protocol CP2 to perform notification. Figure 10 As shown, in a first communication mode, wireless communicator 20W has a first notification and a second notification different from the first notification. In both the first notification and the second notification, wireless communicator 20W is configured to wirelessly transmit a connection request signal CS1 to establish a wireless connection between wireless communicator 20W and additional wireless communicator 24W.

[0118] Additional wireless communicator 24W is configured to wirelessly transmit a connection signal CS2 using the second communication protocol CP2 to establish a wireless connection between wireless communicator 20W and additional wireless communicator 24W. Controller 20C is configured to control wireless communicator 20W to establish a wireless connection between wireless communicator 20W and additional wireless communicator 24W using the second communication protocol CP2 if controller 20C detects the connection signal CS2.

[0119] When the second communication protocol CP2 is Bluetooth or Bluetooth LE, for example, the connection request signal CS1 includes a notification packet having a format specified by the second communication protocol CP2. The notification packet includes a universally unique identifier (UUID) indicating the service of the wireless communication device 20. That is, the wireless communication device 20 corresponds to the peripheral, and each of the additional electrical devices 24, 26, and 28 corresponds to the central.

[0120] like Figure 10 As shown, in the first notification, controller 20C is configured to control wireless communicator 20W to wirelessly transmit a connection request signal CS1 at a first frequency FQ1 during a first period PD1. Controller 20C is configured to control wireless communicator 20W to wirelessly transmit a connection request signal CS1 at a second frequency FQ2 different from the first frequency FQ1 after the first period PD1 has elapsed. Controller 20C is configured to control wireless communicator 20W to wirelessly transmit a connection request signal CS1 at the second frequency FQ2 during a second period PD2 after the first period PD1 has elapsed.

[0121] In other words, controller 20C is configured to control wireless communicator 20W to wirelessly transmit connection request signal CS1 at a first interval V1 during a first period PD1. Controller 20C is configured to control wireless communicator 20W to wirelessly transmit connection request signal CS1 at a second interval V2 different from first interval V1 after the first period PD1 has elapsed. Controller 20C is configured to control wireless communicator 20W to wirelessly transmit connection request signal CS1 at a second interval V2 during a second period PD2 after the first period PD1 has elapsed.

[0122] In this embodiment, the second frequency FQ2 is lower than the first frequency FQ1. The second interval is longer than the first interval. Examples of the first frequency FQ1 include 1 / 100 msec. -1 Examples of the second frequency FQ2 include 1 / 500 msec -1 However, the first frequency FQ1 and the second frequency FQ2 are not limited to this embodiment. The second frequency FQ2 may be higher than the first frequency FQ1.

[0123] In this embodiment, the second period PD2 is different from the first period PD1. The second period PD2 is longer than the first period PD1. However, the second period PD2 may be equal to or shorter than the first period PD1.

[0124] like Figure 10 As shown, controller 20C is configured to control wireless communicator 20W to stop transmitting connection request signal CS1 after a second period PD2 has elapsed. In this embodiment, if wireless communicator 20W does not detect connection signal CS2 during the second period PD2, controller 20C controls wireless communicator 20W to stop transmitting connection request signal CS1 after the second period PD2 has elapsed.

[0125] like Figure 11 As shown, if wireless communicator 20W detects connection signal CS2 before first period PD1 elapses, controller 20C controls wireless communicator 20W to stop transmitting connection request signal CS1 and establishes a wireless connection between wireless communicator 20W and additional wireless communicator 24W.

[0126] like Figure 12 As shown, if wireless communicator 20W detects connection signal CS2 before second period PD2 elapses, controller 20C controls wireless communicator 20W to stop transmitting connection request signal CS1 and establishes a wireless connection between wireless communicator 20W and additional wireless communicator 24W.

[0127] like Figure 13 As shown, in the second notification, controller 20C is configured to control wireless communicator 20W to wirelessly transmit connection request signal CS3 at a third frequency FQ3 during a third time period PD3. In the second notification, controller 20C is configured to control wireless communicator 20W to wirelessly transmit connection request signal CS3 at a third interval V3 during a third time period PD3.

[0128] In the case where the second communication protocol CP2 is Bluetooth or Bluetooth LE, for example, the connection request signal CS3 includes a notification data packet having a format specified based on the second communication protocol CP2. The notification data packet includes a universally unique identifier (UUID) indicating a service of the wireless communication device 20. The connection request signal CS3 is different from the connection request signal CS1. The UUID of the notification data packet of the connection request signal CS3 is different from the UUID of the notification data packet of the connection request signal CS1. For example, the UUID of the notification data packet of the connection request signal CS3 indicates a service for a bicycle computer and an application for a smartphone or tablet computer. The UUID of the notification data packet of the connection request signal CS1 indicates another service for a bicycle computer.

[0129] In this embodiment, the third frequency FQ3 is equal to the first frequency FQ1 and different from the second frequency FQ2. The third frequency FQ3 is higher than the first frequency FQ1. Examples of the third frequency FQ3 include 1 / 100 msec -1 However, the third frequency FQ3 is not limited to this embodiment. The third frequency FQ3 can be different from the first frequency FQ1, and can be equal to or lower than the second frequency FQ2.

[0130] In this embodiment, the third period PD3 is equal to the first period PD1 and different from the second period PD2. The third period PD3 is shorter than the second period PD2. However, the third period PD3 can be equal to or longer than the second period PD2. The third period PD3 can be different from the first period PD1.

[0131] If the wireless communicator 20W does not detect both the connection signal CS2 and the connection signal CS4 during the third period PD3, the controller 20C controls the wireless communicator 20W to stop transmitting the connection request signal CS3 after the third period PD3 elapses.

[0132] As shown in FIG. 6, if the wireless communicator 20W detects the connection signal CS2 or CS4 before the third period PD3 elapses, the controller 20C controls the wireless communicator 20W to stop transmitting the connection request signal CS3 and establishes a wireless connection between the wireless communicator 20W and the additional wireless communicator 24W. Figure 14 Figure 15 As shown in FIG. 6, if the wireless communicator 20W detects the connection signal CS2 or CS4 before the third period PD3 elapses, the controller 20C controls the wireless communicator 20W to stop transmitting the connection request signal CS3 and establishes a wireless connection between the wireless communicator 20W and the additional wireless communicator 24W.

[0133] As shown in FIG. 7, after the first communication mode starts, the controller 20C sets the wireless communicator 20W to the notification state ST11. In the notification state ST11, the controller 20C controls the wireless communicator 20W to wirelessly transmit information using the first communication protocol CP1, and controls the wireless communicator 20W to perform the second notification AD2 Figure 6 Figure 13 ) using the second communication protocol CP2.

[0134] As shown in FIG. 8, in the case where the user uses the additional electric device 24, if the additional wireless communicator 24W is in a mode using the first communication protocol CP1, the controller 24C of the additional electric device 24 controls the display 24D to display information wirelessly transmitted from the wireless communicator 20W using the first communication protocol CP1. In the case where the user uses the additional electric device 28, the controller 28C of the additional electric device 28 controls the display 28D to display information wirelessly transmitted from the wireless communicator 20W using the first communication protocol CP1. Figure 5 As shown in FIG. 7, in the second notification AD2, the controller 20C controls the wireless communicator 20W to wirelessly transmit information using the second communication protocol CP2 for the third period PD3

[0135] Figure 6 As shown in FIG. 7, in the second notification AD2, the controller 20C controls the wireless communicator 20W to wirelessly transmit information using the second communication protocol CP2 for the third period PD3​​​Figure 13 ) Wirelessly transmits a connection request signal CS3 using the second communication protocol CP2.

[0136] If the additional wireless communicator 26W detects the connection request signal CS3, the additional wireless communicator 26W of the additional electrical device 26 wirelessly transmits the connection signal CS4. If the wireless communicator 20W detects the connection signal CS4 during the third period PD3 ( Figure 15 ), controller 20C sets wireless communicator 20W to the second protocol connection state ST12 and stops transmitting wireless signals using the first communication protocol CP1 (step S101). In the second protocol connection state ST12, wireless communicator 20W establishes a wireless connection with additional wireless communicator 26W using the second communication protocol CP2. When the user uses additional electronic device 26, controller 26C of additional electronic device 26 controls display 26D to display information wirelessly transmitted from wireless communicator 20W using the second communication protocol CP2 in the second protocol connection state ST12.

[0137] like Figure 6 As shown, if the wireless connection established between wireless communicator 20W and additional wireless communicator 26W is disconnected, controller 20C sets wireless communicator 20W to notification state ST11 (step S102). Furthermore, if mode switch 20S receives additional user input UW2, controller 20C sets wireless communicator 20W to notification state ST11 (step S103).

[0138] If the additional wireless communicator 24W detects the connection request signal CS1 in the second notification AD2, the additional wireless communicator 24W of the additional electric device 24 wirelessly transmits the connection signal CS2. If the wireless communicator 20W detects the connection signal CS2 ( Figure 14 ), controller 20C sets wireless communicator 20W to dual communication state ST13 (step S104). In dual communication state ST13, wireless communicator 20W establishes a wireless connection with additional wireless communicator 24W using second communication protocol CP2.

[0139] If wireless communicator 20W does not receive connection signals CS2 and CS4 during the third period PD3 ( Figure 13 ), controller 20C sets wireless communicator 20W to notification state ST14 (step S105). In notification state ST14, controller 20C controls wireless communicator 20W to wirelessly transmit information using first communication protocol CP1 and controls wireless communicator 20W to perform first notification AD1 using second communication protocol CP2 ( Figure 10 ).

[0140] If the additional wireless communicator 24W detects the connection request signal CS1 in the first notification AD1, the additional wireless communicator 24W of the additional electric device 24 wirelessly transmits a connection signal CS2. If the wireless communicator 20W detects the connection signal CS2 in the first period PD1 or the second period PD2 of the first notification AD1 (or Figure 11 or Figure 12 ), the controller 20C sets the wireless communicator 20W to the dual communication state ST13 (step S106).

[0141] If the wireless connection established between the wireless communicator 20W and the additional wireless communicator 24W is disconnected, the controller 20C sets the wireless communicator 20W to the notification state ST14 (step S107). If the mode switcher 20S receives the additional user input UW2 in the notification state ST14 or the dual communication state ST13, the controller 20C sets the wireless communicator 20W to the notification state ST11 (step S108).

[0142] If the determined time DT11 elapses from the start of the dual communication state ST13, the controller 20C sets the wireless communicator 20W to the second protocol connection state ST15 (step S109). If the controller 20C detects a determined signal CS5 in the second protocol connection state ST15, the controller 20C sets the wireless communicator 20W to the dual communication state ST13 (step S110). Examples of the determined signal CS5 include the upshift control signal UC1, the downshift control signal DC1, the upshift control signal UC2, and the downshift control signal DC2. Examples of the determined signal CS5 can include other signals. If the mode switcher 20S receives the additional user input UW2 in the second protocol connection state ST15, the controller 20C sets the wireless communicator 20W to the notification state ST11 (step S111).

[0143] If the wireless connection established between the wireless communicator 20W and the additional wireless communicator 24W is disconnected, the controller 20C sets the wireless communicator 20W to the notification state ST16 (step S112). In the notification state ST16, the controller 20C controls the wireless communicator 20W to perform the first notification AD1 using the second communication protocol CP2 (step S113). Figure 10

[0144] If the wireless communicator 20W detects the connection signal CS2 in the first period PD1 or the second period PD2 of the first notification AD1 (or Figure 11 or Figure 12 ​), controller 20C sets wireless communicator 20W to the second protocol connection state ST15 (step S113). If mode switcher 20S receives additional user input UW2 in the notification state ST16, controller 20C sets wireless communicator 20W to the notification state ST11 (step S114).

[0145] If controller 20C detects determination signal CS5 in notification state ST16, controller 20C sets wireless communicator 20W to notification state ST14 (step S115). After completing first notification AD1, if wireless communicator 20W does not receive information wirelessly transmitted from add-on device 24 or 28 using first communication protocol CP1 within determination time DT11, controller 20C sets wireless communicator 20W to a sleep state (step S116).

[0146] If mode switch 20S receives additional user input UW2 in the sleep state, controller 20C sets wireless communicator 20W to notification state ST11 (step S117). If controller 20C detects determination signal CS5 in the sleep state, controller 20C sets wireless communicator 20W to notification state ST14 (step S118).

[0147] If wireless communicator 20W does not detect connection signal CS2 in the first and second time periods PD1 and PD2 ( Figure 10 ), controller 20C sets wireless communicator 20W to the first protocol connection state ST17 after completing first notification AD1 (step S119). When the user uses add-on device 24, controller 24C of add-on device 24 controls display 24D to display information wirelessly transmitted from wireless communicator 20W using the first communication protocol CP1 in the first protocol connection state ST17. When the user uses add-on device 28, controller 28C of add-on device 28 controls display 28D to display information wirelessly transmitted from wireless communicator 20W using the first communication protocol CP1 in the first protocol connection state ST17.

[0148] If mode switch 20S receives additional user input UW2 in the first protocol connection state ST17, controller 20C sets wireless communicator 20W to the notification state ST11 (step S120). If controller 20C detects a determination signal CS5 in the first protocol connection state ST17, controller 20C sets wireless communicator 20W to the notification state ST14 (step S121). If wireless communicator 20W does not receive information wirelessly transmitted from additional electrical device 24 or 28 using the first communication protocol CP1 within the determination time DT11, controller 20C sets wireless communicator 20W to the sleep state (step S122).

[0149] like Figure 7 As shown, after the second communication mode starts, controller 20C sets wireless communicator 20W to notification state ST21. In notification state ST21, controller 20C controls wireless communicator 20W to perform second notification AD2 ( Figure 13 ).

[0150] If wireless communicator 20W detects connection signal CS4 ( Figure 15 ), controller 20C sets wireless communicator 20W to the second protocol connection state ST12 (step S201). If the wireless connection established between wireless communicator 20W and additional wireless communicator 26W is disconnected, controller 20C sets wireless communicator 20W to the notification state ST21 (step S202). Furthermore, if mode switch 20S receives additional user input UW2, controller 20C sets wireless communicator 20W to the notification state ST21 (step S203).

[0151] If wireless communicator 20W detects connection signal CS2 ( Figure 14 ), controller 20C sets wireless communicator 20W to dual communication state ST23 (step S204). In dual communication state ST23, wireless communicator 20W establishes a wireless connection with additional wireless communicator 24W using second communication protocol CP2.

[0152] If wireless communicator 20W does not receive connection signals CS2 and CS4 in the third period PD3 ( Figure 13 ), controller 20C sets wireless communicator 20W to notification state ST24 (step S205). In notification state ST24, controller 20C controls wireless communicator 20W to execute first notification AD1 ( Figure 10 ).

[0153] If wireless communicator 20W detects connection signal CS2 ( Figure 11 or Figure 12 ), controller 20C sets wireless communicator 20W to dual communication state ST23 (step S206). In dual communication state ST23, wireless communicator 20W establishes a wireless connection with additional wireless communicator 24W using first communication protocol CP1 and second communication protocol CP2.

[0154] If the wireless connection established between wireless communicator 20W and additional wireless communicator 24W is disconnected, controller 20C sets wireless communicator 20W to notification state ST24 (step S207). If mode switcher 20S receives additional user input UW2 in notification state ST24 or dual communication state ST13, controller 20C sets wireless communicator 20W to notification state ST21 (step S208).

[0155] If wireless communicator 20W does not detect connection signal CS2 in the first and second time periods PD1 and PD2 ( Figure 10 ), controller 20C sets wireless communicator 20W to the sleep state after completing first notification AD1 (step S219). If mode switcher 20S receives additional user input UW2 in the sleep state, controller 20C sets wireless communicator 20W to the notification state ST11 (step S220). If controller 20C detects determination signal CS5 in the sleep state, controller 20C sets wireless communicator 20W to the notification state ST14 (step S221).

[0156] like Figure 8 As shown, after the third communication mode starts, the controller 20C sets the wireless communicator 20W to the second protocol connection state ST31. If the wireless communicator 20W does not receive information wirelessly transmitted from the additional electrical device 24 or 28 using the first communication protocol CP1 within a certain time DT11, the controller 20C sets the wireless communicator 20W to the sleep state (step S316).

[0157] If mode switch 20S receives additional user input UW2 in the sleep state, controller 20C sets wireless communicator 20W to the second protocol connection state ST31 (step S317). If controller 20C detects determination signal CS5 in the sleep state, controller 20C sets wireless communicator 20W to the second protocol connection state ST31 (step S318).

[0158] like Figure 5As shown, the operating system 10 includes a pedaling sensing device 30. The pedaling sensing device 30 for the human-powered vehicle VH includes a wireless communication device 32 and a pedaling sensor 34. The pedaling sensor 34 is configured to sense a pedaling state.

[0162] The pedaling sensing device 30 includes a power source 48. The power source 48 is electrically connected to the pedaling sensor 34, the wireless communication device 32, the sensing controller, and the cadence sensor to power the pedaling sensor 34, the wireless communication device 32, the sensing controller, and the cadence sensor. For example, the power source 48 is disposed in the crankshaft BC15 Figure 1 ).

[0163] The wireless communication device 32 is configured to wirelessly communicate with other electrical devices, such as the additional electrical device 24, the additional electrical device 26, or the additional electrical device 28.

Therefore, for the sake of brevity, a detailed description will not be given here.

[0167] Second embodiment

[0168] The following will refer to Figure 17 and Figure 18 The operating system 210 including the wireless communication device 220 according to the second embodiment is described. Except for the mode switch 20S, the operating system 210 has the same structure and / or configuration as the operating system 10. Therefore, elements having substantially the same structure and / or configuration as those in the first embodiment are numbered the same herein and, for the sake of brevity, will not be described and / or illustrated in detail herein.

[0169] like Figure 17 As shown, in wireless communication device 220, controller 20C does not use user input UW1 to set the communication mode of wireless communicator 20W. In this embodiment, controller 20C includes memory 220M configured to store mode information MD indicating a selected communication mode. Controller 20C is configured to set wireless communicator 20W to the selected communication mode based on mode information MD. The selected communication mode includes one of a first communication mode and a second communication mode. In this embodiment, the selected communication mode includes one of a first communication mode CM1, a second communication mode CM2, and a third communication mode CM3.

[0170] The controller 20C is configured to receive a mode command MC indicating a selected communication mode from the input device 229. The controller 20C is configured to store the mode command MC as mode information MD in the memory 220M if the controller 20C receives the mode command MC.

[0171] Examples of the input device 229 include the additional electric devices 24, 26, and 28. Each of the additional electric devices 24, 26, and 28 wirelessly transmits a mode command MC indicating a selected communication mode to the wireless communicator 20W. Specifically, a user can select a communication mode among the first to third communication modes on the display 24D, 26D, or 28D. The additional electric device 24, 26, or 28 wirelessly transmits a mode command MC indicating a communication mode selected using the additional electric device 24, 26, or 28.

[0172] As shown in FIG. 8, the controller 20C sets the wireless communicator 20W to the first communication mode CM1 (step S21). The controller 20C determines the mode information MD (step S22). If the mode information MD indicates the first communication mode CM1, the controller 20C sets the wireless communicator 20W to the first communication mode CM1 (step S21 and step S22). If the mode information MD indicates the second communication mode CM2, the controller 20C sets the wireless communicator 20W to the second communication mode CM2 (step S21 and step S23). The routine returns to step S22. If the mode information MD indicates the third communication mode CM3, the controller 20C sets the wireless communicator 20W to the third communication mode CM3 (step S21 and step S24). The routine returns to step S22. Figure 18

[0173] The terms "comprise" and "comprising", when used in this document, are intended to specify the presence of stated features, elements, components, groups, integers and / or steps, but do not preclude the presence or addition of one or more other features, elements, components, groups, integers and / or steps. This applies also to the terms "having", "include", "including" and "contains", "containing" and / or the like.

[0174] The terms "member", "segment", "portion", "part", "element", "body" and "structure", when used in singular, can have a dual meaning of a single part or multiple parts.

[0175] The ordinal numbers recited in this application, such as "first" and "second", are merely identifiers and are not intended to signify a specific order or the like. Furthermore, use of such ordinal numbers is not intended to limit the number of items to those specifically identified. For example, a "first" element does not necessarily signify that only one "second" element can be present.

[0176] The term "a pair", as used herein, can include a configuration in which the pair of elements have different shapes or structures from each other and a configuration in which the pair of elements have the same shape or structure from each other.

[0177] ​The terms "one", "one or more", and "at least one" can be used interchangeably herein.

[0178] Finally, the terms of degree, such as "substantially", "about", and "approximately", as used herein, mean a reasonable amount of deviation of a term so that the end result is not significantly changed. All numerical values described in this application can be interpreted as including terms such as "substantially", "about", and "approximately".

[0179] The phrase "at least one of", as used in this disclosure, means "one or more of". As an example, the phrase "at least one of", as used in this disclosure, if the number of choices is two, means "only one single choice" or "both choices". As another example, the phrase "at least one of", as used in this disclosure, if the number of choices is equal to or greater than three, means "only one single choice" or "any combination of equal to or greater than two choices". For example, the phrase "at least one of A and B" includes (1) A alone, (2) B alone, and (3) both A and B. The phrase "at least one of A, B, and C" includes (1) A alone, (2) B alone, (3) C alone, (4) A and B both, (5) B and C both, (6) A and C both, and (7) A, B, and C all. 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.

[0180] Obviously, many modifications and variations of the present application are possible in light of the above teachings. It is, therefore, to be understood that within the scope of the appended claims, the application can be practiced otherwise than as specifically described.
