A first aspect of the present invention provides a thermometer. The thermometer may have a single button that is pressed by a user. The thermometer may have a control unit that, in a power-on state in which the power is turned on by pressing the button once from a power-off state, starts communication processing with an external communication terminal if the button is pressed once again within a predetermined time, and turns off the power without starting the communication processing if the time has passed without the button being pressed in the power-on state.

If the button is pressed once more during the communication process, the control unit may stop the communication process and turn off the power.

The control unit may turn off the power if the communication process is completed without the button being pressed during the communication process.

The thermometer may further include a display unit that displays information visible to the user when the power is on and ends display of the information when the power is turned off. During the communication process, the control unit may cause the display unit to display the information in a display mode that differs from the display mode before the communication process started.

The thermometer may further include a display unit. During the communication process, the control unit may cause the display unit to display information indicating that the communication process is in progress.

If a predetermined time has elapsed without receiving a response signal from the communication terminal after starting the communication process, the control unit may cause the display unit to display information indicating that communication with the communication terminal has failed, and then turn off the power.

The thermometer may further include a temperature measurement unit. The thermometer may further include a memory unit that stores the most recent measurement result by the temperature measurement unit. In the power-on state, if the measured temperature is confirmed without the button being pressed during temperature measurement by the temperature measurement unit, the control unit may store the temperature measurement result in the memory unit as the most recent measurement result. In the communication process, if the control unit receives a signal requesting data transfer from the communication terminal, it may start transmitting the most recent measurement result stored in the memory unit to the communication terminal, and turn off the power when transmission of the most recent measurement result is complete.

Starting the communication process may include starting to send a signal to the communication terminal to establish communication, and, if a response signal is received from the communication terminal in response, starting either a pairing process with the communication terminal or a data transfer process to the communication terminal in accordance with the response signal.

A second aspect of the present invention provides a communication system. The communication system may include a thermometer. The communication system may include a communication terminal. The thermometer may have a single button that is pressed by a user. The thermometer may have a control unit that, in a power-on state in which the power is turned on by pressing the button once from a power-off state, starts sending a signal to the communication terminal to establish communication if the button is pressed once again within a predetermined time, and turns off the power without starting to send the signal to the communication terminal if the time has elapsed in the power-on state without the button being pressed.

A third aspect of the present invention provides a communication system. The communication system may include a thermometer. The communication system may include a communication terminal. The communication terminal may be set, by a user's operation, to a standby state in which it is in a state where it is ready to start one of a plurality of different communication processes with the thermometer. The thermometer may have a single button that is pressed by a user. The thermometer may have a control unit that, when the button is pressed once again in a power-on state in which the thermometer is turned on by pressing the button once from a power-off state, executes the one communication process with the communication terminal in accordance with the standby state of the communication terminal.

FIG. 4 is a diagram showing an example of a subroutine of step S103 in FIG. 3; 10A to 10C are explanatory diagrams illustrating a series of display examples on the display unit 140 of the thermometer 100. 10A to 10C are explanatory diagrams illustrating a series of display examples on a display unit 210 of a communication terminal 200.

The present invention will be described below through embodiments of the invention, but the following embodiments do not limit the scope of the invention as claimed. Furthermore, not all of the combinations of features described in the embodiments are necessarily essential to the solution of the invention.

Figure 1 is a schematic diagram of an example of a communication system 10. The communication system 10 includes a thermometer 100 and a communication terminal 200. Note that Figure 1 shows an example of the internal configuration of the thermometer 100, which cannot be seen from the outside, using dashed lines.

The thermometer 100 and the communication terminal 200 communicate with each other wirelessly or via a wired connection. As an example, the thermometer 100 and the communication terminal 200 may communicate with each other wirelessly using a short-range wireless communication standard such as Bluetooth (registered trademark), ZigBee (registered trademark), NFC, FeliCa, or Wi-Fi (registered trademark). Note that the users of the thermometer 100 and the communication terminal 200 may be the same person or different people.

The thermometer 100 has a single button 110 that is pressed by the user. The thermometer 100 is operated by the user simply pressing the single button 110. A simple pressing operation refers to the operation of pressing the button 110, and does not refer to a complex operation such as varying the length of time the button 110 is pressed, i.e., the continuous pressing time.

The thermometer 100 is an electronic thermometer that measures the user's body temperature. The thermometer 100 stores the measurement results of the user's body temperature and transmits the measurement results to the communication terminal 200 in response to the user pressing the button 110.

The communication terminal 200 is a communication device with a user interface, and may be, for example, a smartphone or tablet terminal equipped with a touch panel display unit 210. In response to user operations on the user interface, the communication terminal 200 establishes communication with the thermometer 100 and displays measurement results received from the thermometer 100 on the user interface.

A communication system 10 configured as described above transmits the measurement results of a user's body temperature measured with a thermometer 100 from the thermometer 100 to a communication terminal 200, allowing the user of the communication terminal 200 to view the measurement results via the interface of the communication terminal 200. By simplifying the device configuration of the thermometer 100, the communication system 10 not only reduces manufacturing costs and size and improves user convenience, but also allows the thermometer 100 to execute processes that reflect the user's intentions by accepting user operations while it is executing various processes.

Figure 2 is a block diagram of an example of a thermometer 100. The thermometer 100 includes a control unit 120. The thermometer 100 according to this embodiment may further include a power supply 130, a display unit 140, a temperature measurement unit 150, and a memory unit 160. Note that in Figure 2, the flow of signals is indicated by solid black arrows.

When a signal is input from button 110 in response to the user pressing button 110, the control unit 120 controls the operation of each component of the thermometer 100.

For example, when the power supply 130 is off, i.e., in the power-off state, and button 110 is pressed once to input a signal from button 110, the control unit 120 may send a signal to each component of the thermometer 100 to switch the power supply 130 to the on state, i.e., the power-on state. Here, the power-on state may mean that each component of the thermometer 100 is in an operating state, and the power-off state may mean that each component of the thermometer 100 is in a completely stopped state. Alternatively, the power-off state may mean that even if all components are not completely stopped and some components are operating, the display unit 140 is turned off and the current consumption of the thermometer 100 is lower than in the state before the display unit 140 was turned off.

For example, when switching from a power-off state to a power-on state, the control unit 120 may refer to data stored in the memory unit 160 and send a signal to the display unit 140 to display information corresponding to that data.

The control unit 120 may also have a timer 121. As an example, the control unit 120 may execute different processing depending on whether or not the user presses the button 110 within a predetermined time, for example, within 20 minutes, after switching to the power-on state.

For example, if button 110 is pressed once within that time, control unit 120 may start communication processing with communication terminal 200. Alternatively, if button 110 is not pressed even once within that time, control unit 120 may send a signal to power source 130 to switch from the power-on state to the power-off state. Note that this process of switching to the power-off state is sometimes referred to as auto-power-off.

The power supply 130 stores power and supplies power to each component of the thermometer 100 according to control by the control unit 120, regardless of whether the power is on or off. The power supply 130 may, for example, be a battery that can be removed by the user, or a non-removable battery. The power supply 130 may also be a replaceable battery or a rechargeable battery. Note that instead of being equipped with the power supply 130, the thermometer 100 may be able to receive power from an external power source.

The display unit 140 may be, for example, a monochrome liquid crystal panel. When the power is on, the display unit 140 displays information that is visible to the user. The display unit 140 also stops displaying the information when the power supply 130 is turned off.

As shown in FIG. 1, the temperature measurement unit 150 includes a temperature sensor provided on the outer surface of the thermometer 100 and measures the outer surface temperature. For example, when the thermometer is held under the user's armpit, the temperature measurement unit 150 measures the temperature of the armpit. The temperature measurement unit 150 stores the measurement results in the memory unit 160. As an example, the measurement time by the temperature measurement unit 150 may be, for example, 10 minutes.

The memory unit 160 stores the most recent measurement result from the temperature measurement unit 150. The memory unit 160 may store not only the most recent measurement result, but also a temperature measurement history including measurement results from a certain period of time in the past. The memory unit 160 may also store the most recent measurement result from the temperature measurement unit 150 in association with the date and time when the temperature measurement was performed by the temperature measurement unit 150. In this case, for example, the temperature measurement unit 150 may refer to the timer 121 of the control unit 120 and store the most recent measurement result in the memory unit 160 together with information on the date and time of measurement. The memory unit 160 is also referenced by the control unit 120.

In the thermometer 100 having the above configuration, when the button 110 is pressed once more within a predetermined time while the power is on, the control unit 120 starts communication processing with the external communication terminal 200; when the time has passed without the button 110 being pressed while the power is on, the control unit 120 turns off the power supply 130 without starting the communication processing.

In this embodiment, the communication terminal 200 may be set by user operation to a standby state in which it is ready to start one of multiple different communication processes with the thermometer 100. In this case, when the button 110 is pressed once more in the power-on state, the control unit 120 of the thermometer 100 according to this embodiment also executes the one communication process with the communication terminal 200 in accordance with the standby state of the communication terminal 200. The standby state referred to here may refer to, for example, a state in which the communication terminal 200 is on standby to pair with a thermometer with which pairing has not yet been performed, or a state in which the communication terminal 200 is on standby to receive measurement results from a paired thermometer, based on user operation of the user interface of the communication terminal 200.

Figure 3 is a flow diagram of an example of a communication method using communication system 10. As an example, the flow in Figure 3 begins when the user presses button 110 once, causing power supply 130 to change from a power-off state to a power-on state. Note that the following explanation of the flow assumes that the power-on state is maintained until the end of the flow, and redundant explanations will be omitted.

If the button 110 is pressed once more within a predetermined time after the thermometer 100 has switched to the power-on state (step S101: YES), the thermometer 100 starts communication processing with the communication terminal 200 (step S103). If the time has passed without the button 110 being pressed (step S101: NO), the thermometer 100 turns off the power supply 130 (step S105) without starting communication processing with the communication terminal 200, and ends the flow. As a specific example, the control unit 120 of the thermometer 100 may use the timer 121 to start measuring time from the time the thermometer 100 is switched to the power-on state, and determine whether a signal based on the pressing of the button 110 is input within, for example, 20 minutes.

In step S101, if the temperature measurement unit 150 measures the temperature before the button 110 is pressed once more within the time period, the control unit 120 stores the measurement result of the temperature measurement in the memory unit 160, i.e., updates the temperature measurement result stored in the memory unit 160. As a further specific example in this case, if the button 110 is not pressed during temperature measurement by the temperature measurement unit 150 and the measured temperature is confirmed, for example, if no error occurs, the control unit 120 may store the result of the temperature measurement in the memory unit 160 as the most recent measurement result.

In step S101, if the temperature measurement unit 150 does not perform a temperature measurement before the button 110 is pressed once more within the predetermined time, the control unit 120 does not update the temperature measurement result stored in the memory unit 160. Also, in step S101, if the temperature measurement unit 150 performs a temperature measurement but an error occurs before the button 110 is pressed once more within the predetermined time, the control unit 120 may not need to update the temperature measurement result stored in the memory unit 160.

Following step S103, if the button 110 is pressed once more during communication processing with the communication terminal 200 (step S107: YES), the thermometer 100 stops the communication processing, turns off the power supply 130 (step S109), and ends the flow. If the communication processing is completed without the button 110 being pressed during the communication processing (step S107: NO), the thermometer 100 turns off the power supply 130 (step S111), and ends the flow.

Figure 4 shows an example of a subroutine of step S103 shown in Figure 3. As a specific example of step S103 shown in Figure 3, starting the communication process may include the thermometer 100 starting to transmit a signal to the communication terminal 200 to establish communication. Starting the communication process may further include, when the thermometer 100 receives a response signal from the communication terminal 200 in response to starting transmission of the signal, starting either one of a pairing process with the communication terminal 200 or a data transfer process to the communication terminal 200 in accordance with the response signal.

In one example of the subroutine in FIG. 4, the thermometer 100 transmits a signal to the communication terminal 200 to establish communication (step S201). The thermometer 100 and the communication terminal 200 may communicate with each other via Bluetooth (registered trademark), in which case the thermometer 100 may continuously transmit advertising packets to the communication terminal 200 in step S201.

When the communication terminal 200 receives a signal to establish communication from the thermometer 100 (step S201), if the thermometer 100 is not paired (step S203: NO), it sends a first signal to the thermometer 100 requesting the start of pairing processing with the communication terminal 200 (step S205). If the thermometer 100 is paired in step S201 (step S203: YES), the communication terminal 200 sends a second signal to the thermometer 100 requesting data transfer (step S207).

When the thermometer 100 receives the first signal from the communication terminal 200 (step S205), it starts the pairing process with the communication terminal 200 (step S209) and proceeds to step S107 in FIG. 3. In this case, step S107: NO in FIG. 3 corresponds to the completion of pairing with the communication terminal 200 without the button 110 being pressed during the pairing process with the communication terminal 200.

When the thermometer 100 receives the second signal from the communication terminal 200 (step S207), it starts the data transfer process, i.e., transmitting the most recent measurement result stored in the memory unit 160 to the communication terminal 200 (step S209), and proceeds to step S107 in Figure 3. In this case, step S107: NO in Figure 3 corresponds to the completion of transmission of the most recent measurement result from the thermometer 100 to the communication terminal 200 without the button 110 being pressed during the transmission process to the communication terminal 200.

The most recent measurement result stored in the memory unit 160 may be linked to the date and time when the temperature measurement was performed by the temperature measurement unit 150. In this case, the control unit 120 may transmit the most recent measurement result stored in the memory unit 160 to the communication terminal 200 together with the date and time linked to the most recent measurement result.

Figure 5 is an explanatory diagram illustrating a series of display examples on the display unit 140 of the thermometer 100. For the sole purpose of explanation, Figure 5 shows corresponding square display areas 141, 142, 143, 144, 145, and 146 in dashed lines for display examples 140A, 140B, 140C, and 140D of the display unit 140, respectively. For the same purpose, Figure 5 also shows a state in which part or the entire display screen of the display unit 140 is flashing using multiple gray triangles. Furthermore, Figure 5 uses hollow arrows to indicate the order of change in the multiple display examples.

5, display unit 140 displays display example 140A in response to thermometer 100 switching from a power-off state to a power-on state. Display example 140A shows a state in which the display screen of display unit 140 is fully lit. In display example 140A, display area 141 is a display area for the measured temperature, display area 142 is a display area for the symbol °C, and display area 143 is a display area for the symbol MR, which indicates that the most recent measurement result stored in memory unit 160 is being displayed. Display area 144 is a display area for a symbol indicating that pairing with communication terminal 200 has been completed and Bluetooth (registered trademark) communication has been established. Display area 145 is a display area for a symbol indicating the remaining battery level of power source 130, and display area 146 is a display area for a prediction symbol. The same applies to other display examples, and redundant explanations will be omitted.

Display example 140B shows a state in which the most recent measurement result stored in memory unit 160 is displayed in display area 141 by lighting up. Display example 140C shows a state in which measurement preparation is complete, with the symbol L being displayed in display area 141 by lighting up and the symbol °C being displayed in display area 142 by flashing. As an example, display unit 140 may display display example 140B two seconds after displaying display example 140A, and may display display example 140C two seconds after displaying display example 140B.

Display example 140D shows a state in which the most recent measurement result stored in memory unit 160 is displayed by flashing in display area 141 and the symbol °C or the like in display area 142 is also displayed by flashing to notify the user that a data transfer process is in progress. The most recent measurement result may be the previous measurement result shown in display example 140B, or may be a measurement result measured by temperature measurement unit 150 and stored in memory unit 160 after display unit 140 displayed display example 140C. As an example, while display unit 140 is displaying any of display example 140A, display example 140B, or display example 140C, it may display display example 140D if a signal is input from control unit 120 in response to the user pressing button 110. As a more specific example, if the user presses button 110 on thermometer 100 but does not press button 110 again, display unit 140 will switch the display at intervals of several seconds between display example 140A, display example 140B, and display example 140C. If the user presses button 110 again during this time, display unit 140 will immediately switch to display example 140D, meaning that control unit 120 will immediately start communication processing.

During communication processing with the communication terminal 200, the control unit 120 of the thermometer 100 may cause the display unit 140 to display information in a display mode different from the display mode before the communication processing began. As a specific example, while the display unit 140 is mainly displaying one of display examples 140A, 140B, and 140C by lighting up, the control unit 120 may cause display example 140D to flash, which is an example of a display mode different from lighting up, in response to the start of communication processing with the communication terminal 200. This allows the thermometer 100 to notify the user that data transfer from the thermometer 100 to the communication terminal 200 has begun and that data transfer is in progress. The user checking the display unit 140 can, for example, recognize that the data transfer processing has not finished and can press the button 110 once more to cancel the processing.

Instead of displaying the different display modes described above on the display example 140, the control unit 120 may display information indicating that the communication process is in progress, such as a symbol indicating that data is being transferred, on the display unit 140 during the communication process. As an example, the data transfer time from the thermometer 100 to the communication terminal 200 is, for example, as short as approximately 10 seconds.

Figure 6 is an explanatory diagram illustrating a series of display examples on the display unit 210 of the communication terminal 200. For the purpose of explanation only, Figure 6 shows corresponding rectangular display areas 211, 212, 213, 214, and 215 in display examples 210A and 210B of the display unit 210, respectively, indicated by dashed lines. Note that Figure 6 uses hollow arrows to indicate that multiple display examples can be switched between each other.

Display example 210A shows a history screen that displays the temperature measurement results and measurement date and time history received by communication terminal 200 from thermometer 100. In display example 210A, display area 211 is a display area for icons that accept a user's tap operation to switch the display screen between display example 210A and display example 210B. Display area 213 is a display area for input fields that accept a user's tap operation to switch between the list display and graph display in display example 210A.

The communication terminal 200 may be capable of displaying a history screen configured to not update the history shown in display example 210A if the history includes a temperature measurement result and measurement date and time newly received from the thermometer 100. This allows the communication terminal 200 to prevent a decrease in user convenience due to an unnecessary increase in history information. In this case, the communication terminal 200 may also delete the temperature measurement result, etc. newly received from the thermometer 100.

Display example 210B shows a device registration screen that distinguishes between the IDs of paired thermometers for which pairing has been completed and the IDs of unpaired thermometers for which pairing has not been completed and for which it has been confirmed that advertising packets are being transmitted. In display example 210B, display area 214 is a display area for the IDs of unpaired thermometers for which pairing has not been completed and it has been confirmed that advertising packets are being transmitted. Display area 215 is a display area for the IDs of paired thermometers for which pairing has been completed.

The communication terminal 200 may be capable of displaying a device registration screen configured to send a response signal to an unpaired thermometer to start the pairing process with the communication terminal 200 in response to a tap on the display area 214 of the ID of the unpaired thermometer. More specifically, the communication terminal 200 may display a list of the IDs of all unpaired thermometers that are receiving a signal to establish communication in the display area 214, and send a signal requesting the start of the pairing process to a specific unpaired thermometer selected by the user by tapping on the display area 214.

The communication terminal 200 may store the IDs of paired thermometers that have completed pairing, and display the IDs of all stored paired thermometers in the display area 215. The communication terminal 200 may display a list of the IDs of all paired thermometers that are receiving a signal to establish communication in the display area 215, and may transmit a signal requesting the start of data transfer processing to a specific paired thermometer selected by the user by tapping on the display area 215.

Here, examples of thermometers that can be compared to the thermometer 100 according to this embodiment include thermometers equipped with multiple buttons that can be pressed by the user, thermometers that require the user to perform complex button press operations by varying the duration of successive button presses for one or more buttons, and thermometers that execute communication processing with an external terminal every time the thermometer is placed in a case. However, if a thermometer has multiple buttons, the manufacturing cost and size of the thermometer increase. Furthermore, if the thermometer requires the user to perform complex button press operations, user convenience decreases. Furthermore, if communication processing is initiated every time the thermometer is placed in a case, the communication processing may be initiated against the user's will, and the user cannot stop the communication processing. In this case, the thermometer's battery is wasted against the user's will, and measurement results that the user does not need are recorded on the user's communication terminal.

In contrast, in this embodiment, with the thermometer 100 having a single button 110, if the button 110 is pressed once more within a predetermined time while the power is on, communication processing with the communication terminal 200 is initiated; if the time elapses without the button 110 being pressed, the communication processing is not initiated and the power supply 130 is turned off.

The user of the thermometer 100 according to this embodiment can freely choose to either power off the thermometer 100 without starting communication processing between the thermometer 100 and the communication terminal 200 by pressing the single button 110 of the thermometer 100 once when the thermometer 100 is in a power-on state, or to start the communication processing by not pressing the button 110 once more within a predetermined time. In other words, the user can choose to automatically power off the thermometer 100 by leaving the thermometer 100 without pressing the button 110, or to start communication processing by pressing the button 110 once, regardless of the continuous pressing time, depending on their own will. In this way, the thermometer 100 not only simplifies the device configuration of the thermometer 100, thereby reducing its size and improving user convenience, but also reflects the user's will by executing different processing depending on whether the user presses the button 110 once more within a predetermined time.

Furthermore, according to the thermometer 100, as an example, if the button 110 is pressed once more during communication processing with the communication terminal 200, the communication processing is stopped and the power supply 130 is turned off; and if the communication processing is completed without the button 110 being pressed during the communication processing, the power supply 130 is turned off. The user of the thermometer 100 according to this embodiment can stop the started communication processing at their own will, even if communication processing between the thermometer 100 and the communication terminal 200 is started willingly or against their will. In this way, the thermometer 100 can execute processing that reflects the user's will by accepting user operations even while communication processing is being executed. This prevents the thermometer 100 from wasting the thermometer's battery against the user's will or from recording measurement results that the user does not need on the user's communication terminal, as in the comparative example.

Furthermore, according to the communication system 10 of this embodiment, as an example, the communication terminal 200 can be set to a standby state in which it is ready to start one of multiple different communication processes with the thermometer 100 through user operation. In this case, for example, when the button 110 is pressed once more while the thermometer 100 is powered on, the thermometer 100 executes the communication process with the communication terminal 200 in accordance with the standby state of the communication terminal 200. Thus, according to the communication system 10, one of multiple different communication processes can be set through user operation on the communication terminal 200. This allows the user's intention to be reflected in the content of the communication process between the thermometer 100 and the communication terminal 200 without complicating the user operation on the thermometer 100, which has a single button 110. For example, among the comparative examples described above, in a thermometer that always executes communication with an external terminal every time the thermometer is placed in a case, communication with the external terminal is initiated when the user finishes using the thermometer and places it in the case, i.e., when the user handles the thermometer, separate from the user's button operation on the thermometer. In contrast, the communication system 10 according to this embodiment, having the above configuration, makes it possible to start communication processing between the thermometer 100 and the communication terminal 200 within the range of user operation of the thermometer 100, i.e., within the range of operation of a single button 110 on the thermometer 100.

In the above multiple embodiments, the control unit 120 of the thermometer 100 has been described as being configured to stop communication processing and turn off the power supply 130 if the button 110 is pressed once more during communication processing with the communication terminal 200, and to turn off the power supply 130 if the communication processing is completed without the button 110 being pressed during the communication processing. In addition, if a predetermined time has passed since the control unit 120 started the communication processing without receiving a response signal from the communication terminal 200, the control unit 120 may display information on the display unit 140 indicating that communication with the communication terminal 200 has failed, and then turn off the power supply 130.

More specifically, the control unit 120 may use the timer 121 to measure the time until a timeout occurs and terminate the communication process when that time has elapsed. As an example, that time may be, for example, 60 seconds.

In the above multiple embodiments, the control unit 120 of the thermometer 100 has been described as being configured not to take into account the length of time the user has continuously pressed the button 110, i.e., as being configured to execute different processes depending on the number of times and/or timing of button presses within a predetermined period of time, regardless of the length of time the button has been continuously pressed. In addition, the control unit 120 may execute different processes depending on the length of time the user has continuously pressed the button 110.

For example, the control unit 120 may execute a process different from that described in the above embodiment if the user continuously presses the button 110 to switch from the power-off state to the power-on state for a predetermined period of time or longer. As a more specific example, if the period of time is, for example, two seconds or longer, the control unit 120 may switch the display screen of the display unit 140 to a screen that allows the user to select whether to enable or disable a function for processing data transfer from the thermometer 100 to the communication terminal 200. Furthermore, the control unit 120 may determine whether to enable or disable the function based on the content displayed on the display screen of the display unit 140 at the time the user stops pressing the button 110. This also allows the thermometer 100 to execute a process that reflects the user's intention. Furthermore, by not including a dedicated switch for enabling or disabling the function, the thermometer 100 can reduce manufacturing costs and size. Note that the control unit 120 may indicate to the user that the data transfer processing function is enabled by lighting up the symbol displayed in the display area 144 in each of the display examples 140B and 140C in FIG. 5, for example, and may indicate to the user that the data transfer processing function is disabled by turning off the symbol. Note that the thermometer 100 may additionally have any other optional functions, such as a waterproof function.

The present invention has been described above using embodiments, but the technical scope of the present invention is not limited to the scope described in the above embodiments. It will be clear to those skilled in the art that various modifications and improvements can be made to the above embodiments. Furthermore, to the extent that there is no technical inconsistency, the details described for a particular embodiment can be applied to other embodiments. Furthermore, each component may have the same characteristics as other components with the same name but different reference numerals. It is clear from the claims that such modifications and improvements can also be included within the technical scope of the present invention.

The order of execution of each process, such as operations, procedures, steps, and stages, in the devices, systems, programs, and methods shown in the claims, specifications, and drawings is not specifically stated as "before," "prior to," or the like, and it should be noted that processes can be performed in any order, unless the output of a previous process is used in a subsequent process. Even if the operational flow in the claims, specifications, and drawings is described using "first," "next," etc. for convenience, this does not mean that it is necessary to perform the processes in that order.
