Hereinafter, an embodiment of the communication connection destination selection system, the communication connection destination selection device, and the communication connection destination selection method will be described with reference to FIGS. 1 to 4.
As shown in FIG. 1, the vehicle 2 as the article 1 includes an authentication system 4 that executes authentication of the terminal 3 by wireless communication. For example, short-range wireless communication is used for the communication of the authentication system 4 of this example. For short-range wireless communication, for example, PAN (Personal Area Network) communication is used, and in this example, Bluetooth (Bluetooth: registered trademark) is used as an example of PAN communication. For Bluetooth communication, for example, it is preferable to use BLE (Bluetooth Low Energy) communication. The terminal 3 is preferably, for example, a high-performance mobile phone.

The vehicle 2 includes a controller 6 that controls the device 5 based on the authentication result of the authentication system 4, and a wireless authentication device 7 that authenticates the terminal 3 through short-range wireless communication. The wireless authentication device 7 includes an authentication unit 8 that executes authentication of the terminal 3 and a communication unit 9 that transmits and receives various radio waves of short-range wireless communication. The authentication unit 8 executes short-range wireless communication with the terminal 3 and authentication through the communication via the communication unit 9. The device 5 includes, for example, a door lock control device that controls the locking and unlocking of the vehicle door, an engine control device that controls the engine, and the like.

The terminal 3 includes a terminal control unit 11 that controls the operation of the terminal 3, a short-range wireless antenna 12 that executes short-range wireless communication at the terminal 3, a network communication antenna 13 that executes network communication at the terminal 3, and a display 14. And a memory 15 for storing various data. The terminal 3 performs short-range wireless communication with the vehicle 2 via the short-range wireless antenna 12. The terminal 3 communicates with the outside (in this example, the server 16) via the network communication antenna 13.

When the server 16 receives the distribution request of the key information Dk used for authentication with the vehicle 2 from the terminal 3 by network communication, the server 16 generates the key information Dk and distributes the key information Dk to the terminal 3 by network communication. When the terminal 3 receives the key information Dk from the server 16, it registers the key information Dk in the memory 15. The terminal 3 can be used as the key of the vehicle 2 by registering the distributed key information Dk in the memory 15. The key information Dk is preferably a one-time password (one-time key) that is permitted to be used only once or for a certain period of time, for example.

In the case of this example, the terminal 3 includes a main terminal 17 possessed by the owner of the article 1 (in this example, the vehicle 2) and a plurality of child terminals 18 (first child terminals 18a, which are positioned lower than the main terminal 17). There are a second child terminal 18b and a third child terminal 18c). Whether the terminal 3 is set as the main terminal 17 or the child terminal 18 is determined, for example, when registering a user on the server 16 when using the authentication system 4, or transmitting a key information Dk distribution request from the terminal 3 to the server 16. Sometimes it is preferred to be set by the user.

The terminal 3 transmits the key information Dk registered in the memory 15 to the vehicle 2 by the short-range wireless communication during the short-range wireless communication when the vehicle 2 is operated by the terminal 3. When the communication unit 9 receives the key information Dk transmitted from the terminal 3, the authentication unit 8 authenticates the key information Dk. At this time, the authentication unit 8 authenticates the key information Dk by confirming whether or not the key information Dk received from the terminal 3 can be correctly decrypted. If the key information Dk can be correctly decrypted, the authentication unit 8 establishes the authentication and continues the process. On the other hand, if the key information Dk cannot be correctly decrypted, the authentication unit 8 fails the authentication and ends the short-range wireless communication.

If the key information Dk can be correctly decrypted, the authentication unit 8 acquires various information included in the key information Dk. In the case of this example, the key information Dk includes, for example, the usable period of the key information Dk, a unique ID (terminal ID) possessed by the terminal 3, a predetermined session key used for subsequent short-range wireless communication, and the like. Is done. When the decryption of the key information Dk is completed correctly, both the terminal 3 and the authentication unit 8 shift to the authentication completed state, and thereafter, when the vehicle door is locked / unlocked or the vehicle power supply is changed, the short-range radio using the session key is used. Communication can be carried out.

When the door handle outside the vehicle is touch-operated when the vehicle door is locked, the terminal 3 and the authentication unit 8 that have transitioned to the authentication completed state execute encrypted communication using the session key. When the authentication unit 8 confirms that the encrypted communication with the terminal 3 located outside the vehicle is normally completed, the authentication unit 8 permits the unlocking of the vehicle door. When the lock button on the door handle outside the vehicle is pressed when the vehicle door is locked, the terminal 3 and the authentication unit 8 that have transitioned to the authentication completed state execute encrypted communication using the session key. When the authentication unit 8 confirms that the encrypted communication with the terminal 3 located outside the vehicle is normally completed, the authentication unit 8 permits the vehicle door to be locked.

When the engine switch in the vehicle is pushed, the terminal 3 and the authentication unit 8 that have transitioned to the authentication completed state execute encrypted communication using the session key. When the authentication unit 8 confirms that the encrypted communication with the terminal 3 located in the vehicle is normally completed, the authentication unit 8 permits the transition operation of the vehicle power supply by the engine switch. Therefore, if the engine switch is pushed while the brake pedal is depressed, the engine will start.

The authentication system 4 includes a function (communication connection destination selection system 22) in which the wireless authentication device 7 selects a terminal 3 to be a connection destination. The communication connection destination selection system 22 of this example transmits the connection priority information Dt in which the connection priority order of the terminal 3 to the wireless authentication device 7 is set to the management device 23 (in this example, the server 16) and registers it. Then, the connection priority information Dt is appropriately transmitted to the vehicle 2 via a network and distributed. Then, when the terminal 3 and the wireless authentication device 7 perform short-range wireless communication, when a plurality of terminals 3 exist around the vehicle 2, the communication connection is based on the connection priority information Dt distributed to the vehicle 2 via the network. Have the terminal 3 selected first.

The vehicle 2 includes a first network communication unit 25 capable of communicating with the first relay server 24 by the first network communication. The first network communication unit 25 is connected to the authentication unit 8 via a communication line 26 in the vehicle. The first relay server 24 relays the first network communication between the terminal 3 and the server 16. The first network communication is preferably Internet communication using, for example, a DCM (Data Communication Module: vehicle-dedicated communication device).

The vehicle 2 includes a second network communication unit 28 capable of communicating with the second relay server 27 by the second network communication. The second network communication unit 28 is connected to the controller 6. The second relay server 27 relays the second network communication between the terminal 3 and the server 16. In the case of this example, the second relay server 27 communicates with the terminal 3 via the base station 29. The second network communication is preferably base station communication by, for example, LPWA (Low Power Wide Area).

The communication connection destination selection system 22 includes a registration unit 32 that transmits and registers the connection priority information Dt to the server 16 as the management device 23. The registration unit 32 includes a registration unit 32a provided in the terminal 3 (in this example, the main terminal 17) and a registration unit 32b provided in the server 16. The registration unit 32 causes the main terminal 17 or the external device 33 to input the connection priority information Dt in which the connection priority order of the terminal 3 is set to the wireless authentication device 7, and the connection priority information Dt is input to the server 16 by network communication. It is transmitted and registered in the server 16. The registration unit 32b stores the network-received connection priority information Dt in the database 34 of the server 16. The external device 33 includes, for example, a personal computer owned by the user.

The communication connection destination selection system 22 includes a notification unit 36 that distributes the connection priority information Dt registered in the server 16 as the management device 23 to the wireless authentication device 7 via a network. The notification unit 36 is provided in the server 16. The notification unit 36 notifies the wireless authentication device 7 from the server 16 of the connection priority information Dt registered in the server 16 by network communication. The notification unit 36 of this example may transmit the connection priority information Dt to the wireless authentication device 7 using either the communication network of the first network or the communication network of the second network. When the notification unit 36 accepts the reservation of the vehicle 2, it is preferable that the connection priority information Dt related to the vehicle 2 is network-distributed to the vehicle 2 for which the reservation has been made.

The communication connection destination selection system 22 includes a selection unit 37 that selects the terminal 3 to be the connection destination when the wireless authentication device 7 communicates with the terminal 3. The selection unit 37 is provided in the wireless authentication device 7 (authentication unit 8). When the terminal 3 and the wireless authentication device 7 communicate with each other, the selection unit 37 sets the terminal 3 to be the connection destination of the communication based on the connection priority information Dt notified from the server 16. The selection unit 37 selects the terminal 3 having the highest connection priority based on the connection priority information Dt among the terminals 3 that have responded to the advertisement (in this example, the existence confirmation advertisement Ad) that is periodically transmitted from the wireless authentication device 7. It is selected and the wireless authentication device 7 is allowed to communicate with the terminal 3.

Next, the operation of the communication connection destination selection system 22 of the present embodiment will be described with reference to FIGS. 2 to 4.
As shown in FIG. 2, the user registers the connection priority information Dt in the server 16 in advance by using the terminal 3. It is preferable that the registration of the connection priority information Dt to the server 16 is, for example, an operation permitted only by the main terminal 17.

As a specific example of the registration work of the connection priority information Dt, for example, the registration unit 32a of the main terminal 17 transmits a registration execution request to the server 16 when the registration operation is executed on the main terminal 17. When the registration unit 32b of the server 16 receives the registration execution request from the main terminal 17, it determines the vehicle 2 related to the main terminal 17 that has sent the registration execution request, and the terminal 3 (main terminal 17) registered in the vehicle 2. And the child terminal 18) are read. The registration unit 32b of the server 16 causes the display 14 of the main terminal 17 to display a screen on which the connection priority of the read terminal 3 (main terminal 17 and child terminal 18) to the wireless authentication device 7 can be set. The user operates the screen on the main terminal 17 to input the connection priority for each terminal 3. The registration unit 32a of the main terminal 17 returns the input result of the connection priority to the server 16. The registration unit 32b of the server 16 stores the input result returned from the main terminal 17 in the database 34 as the connection priority information Dt.

Subsequently, it is assumed that a user operates the terminal 3 to transmit the usage reservation of the vehicle 2 to the server 16 via the network. At this time, the terminal 3 for which the usage reservation is made may be either the main terminal 17 or the child terminal 18.

When the server 16 inputs the usage reservation from the terminal 3 of a certain user, the server 16 transmits the connection priority information Dt registered in the database 34 of the server 16 to the vehicle 2 in which the usage reservation is entered. For the network transmission of the connection priority information Dt to the vehicle 2, either the first network communication or the second network communication may be used. As a result, the latest connection priority information Dt is registered in the vehicle 2.

As shown in FIG. 3A, for the vehicle 2 in which the connection priority information Dt is registered, the terminal 3 (in this example, the first child terminal 18a) is in the communication area E2 of the communication unit 9 of the wireless authentication device 7. Has entered. When the terminal 3 enters the communication area E2 where the radio waves from the communication unit 9 reach, the terminal 3 is in a state of receiving the existence confirmation advertisement Ad transmitted from the wireless authentication device 7, and returns the response to the wireless authentication device 7. do. When the wireless authentication device 7 can receive the response to the existence confirmation advertisement Ad, it subsequently transmits the communication connection advertisement Ae, and if it can receive the response to this, the short-range wireless communication shifts to the state of the communication connection.

By the way, the terminal 3 is connected to the wireless authentication device 7 on the condition that the received signal strength when receiving the radio wave (for example, communication connection advertisement Ae) transmitted from the wireless authentication device 7 is equal to or higher than the reception threshold value. The operation of transmitting the connect request for shifting the short-range wireless communication of the above to the connection to the wireless authentication device 7 is executed. Therefore, the received signal strength does not exceed the reception threshold value only by entering the communication area E2, which is a position far from the wireless authentication device 7, and at this point, the short-range wireless communication does not yet shift to the communication connection state. ..

When the wireless authentication device 7 transmits the communication connection advertisement Ae, if the response, that is, the connect request cannot be received within a certain period of time, the wireless authentication device 7 returns to the operation of transmitting the existence confirmation advertisement Ad. Then, the wireless authentication device 7 repeats the above-described operation until the connect request can be received from the terminal 3.

As shown in FIG. 3B, it is assumed that the first child terminal 18a further approaches the vehicle 2 and enters the communication area E1, and the second child terminal 18b enters the communication area E2. In the communication area E1, the received signal strength when receiving the radio wave transmitted from the wireless authentication device 7 becomes equal to or higher than the reception threshold value, and the first child terminal 18a entering the communication area E1 is connected by short-range wireless communication. It is possible to shift to the state of. On the other hand, since the second child terminal 18b has entered the communication area E2, it is ready to receive the existence confirmation advertisement Ad transmitted from the wireless authentication device 7.

FIG. 4 illustrates a specific example of a connection sequence of short-range wireless communication executed between the terminal 3 and the wireless authentication device 7. Here, as described above, it is assumed that the first child terminal 18a and the second child terminal 18b approach the vehicle 2, and specifically, the first child terminal 18a enters the communication area E1 around the vehicle. , It is assumed that the second child terminal 18b is located in the communication area E2 further away.

In step 101, the selection unit 37 acquires the connection priority information Dt from the server 16 in advance. In the case of this example, the selection unit 37 receives the connection priority information Dt when the connection priority information Dt is network-distributed from the server 16 when the usage reservation for the vehicle 2 is made, and the wireless authentication device 37 receives the connection priority information Dt. It is written and held in the memory area of 7.

In step 102, the selection unit 37 requests the issuance of the existence confirmation advertisement Ad to confirm which terminal 3 exists in the vicinity, and the existence confirmation advertisement Ad to the main terminal 17 (existence confirmation advertisement issuance Ad1 for the main terminal). Is output to the communication unit 9. In the case of this example, the selection unit 37 takes an operation of sequentially transmitting the existence confirmation advertisement Ad of the terminal 3 related to the setting of the connection priority. In the example of the figure, for example, the existence confirmation advertisement Ad is repeatedly transmitted in the order of the main terminal 17, the first child terminal 18a, the second child terminal 18b, and the third child terminal 18c.

In step 103, when the communication unit 9 receives the issuance request of the existence confirmation advertisement Ad1 for the main terminal from the selection unit 37, the communication unit 9 transmits the existence confirmation advertisement Ad1 for the main terminal as the existence confirmation advertisement Ad. The existence confirmation advertisement Ad1 for the main terminal is preferably ADV_SCAN_IND in which a flag indicating the main terminal 17 is set in the message, for example.

Here, since the example in which the first child terminal 18a and the second child terminal 18b approach the vehicle 2 is given, the main terminal 17 does not exist around the vehicle 2. Therefore, even if the selection unit 37 transmits the existence confirmation advertisement Ad1 for the main terminal, the selection unit 37 cannot receive a response (scan request) to the transmission. Therefore, the selection unit 37 recognizes that the main terminal 17 does not exist in the communication area E1 around the vehicle because the response to the existence confirmation advertisement Ad1 for the main terminal cannot be received.

In step 104, after transmitting the existence confirmation advertisement Ad1 for the main terminal, the selection unit 37 requests the issuance of the existence confirmation advertisement Ad (existence confirmation advertisement Ad2 for the first child terminal) toward the first child terminal 18a. Output to.

In step 105, when the selection unit 37 receives the issuance request of the existence confirmation advertisement Ad2 for the first child terminal from the selection unit 37, the selection unit 37 transmits the existence confirmation advertisement Ad2 for the first child terminal. The existence confirmation advertisement Ad2 for the first child terminal is preferably ADV_SCAN_IND in which a flag indicating the first child terminal 18a is set in the message, for example. Here, since the example in which the first child terminal 18a exists around the vehicle 2 is given, the first child terminal 18a receives the existence confirmation advertisement Ad2 for the first child terminal transmitted from the vehicle 2 side.

In step 106, when the first child terminal 18a receives the existence confirmation advertisement Ad2 for the first child terminal, which is the existence confirmation advertisement Ad2 for itself, the first child terminal 18a transmits a scan request to the vehicle 2 as a response to the reception.

In step 107, when the communication unit 9 receives the scan request from the first child terminal 18a, the communication unit 9 outputs the scan information to the selection unit 37. When the selection unit 37 inputs the scan information in response to the issuance request of the existence confirmation advertisement Ad2 for the first child terminal, the selection unit 37 recognizes that the first child terminal 18a has entered the communication area E1 around the vehicle.

In step 108, when the communication unit 9 receives the scan request from the first child terminal 18a, the communication unit 9 transmits a scan response notifying that the scan request has been received to the first child terminal 18a. When the first child terminal 18a receives the scan response, it waits for the communication connection advertisement Ae to be transmitted next.

In step 109, the selection unit 37 inputs the scan information by communicating with the first child terminal 18a, and then the existence confirmation advertisement Ad for the second child terminal 18b (existence confirmation advertisement issue Ad3 for the second child terminal). The issue request is output to the communication unit 9.

In step 110, when the selection unit 37 receives the issuance request of the existence confirmation advertisement Ad3 for the second child terminal from the selection unit 37, the selection unit 37 transmits the existence confirmation advertisement Ad3 for the second child terminal. The existence confirmation advertisement Ad3 for the second child terminal is preferably ADV_SCAN_IND in which a flag indicating the second child terminal 18b is set in the message, for example. Here, since the example in which the second child terminal 18b exists around the vehicle 2 is given, the second child terminal 18b receives the existence confirmation advertisement Ad3 for the second child terminal transmitted from the vehicle 2 side.

In step 111, when the second child terminal 18b receives the existence confirmation advertisement Ad3 for the second child terminal, which is the existence confirmation advertisement Ad 3 for itself, the second child terminal 18b transmits a scan request to the vehicle 2 as a response to the reception.

In step 112, when the communication unit 9 receives the scan request from the second child terminal 18b, the communication unit 9 outputs the scan information to the selection unit 37. When the selection unit 37 inputs the scan information in response to the issuance request of the existence confirmation advertisement Ad3 for the second child terminal, the selection unit 37 recognizes that the second child terminal 18b exists around the vehicle.

In step 113, when the communication unit 9 receives the scan request from the second child terminal 18b, the communication unit 9 transmits a scan response notifying that the scan request has been received to the second child terminal 18b. When the second child terminal 18b receives the scan response, it waits for the communication connection advertisement Ae to be transmitted next.

In step 114, the selection unit 37 inputs the scan information by communicating with the second child terminal 18b, and then the existence confirmation advertisement Ad for the third child terminal 18c (existence confirmation advertisement issue Ad4 for the third child terminal). The issue request is output to the communication unit 9.

In step 115, when the selection unit 37 receives the issuance request of the existence confirmation advertisement Ad4 for the third child terminal from the selection unit 37, the selection unit 37 transmits the existence confirmation advertisement Ad4 for the third child terminal. The existence confirmation advertisement Ad4 for the third child terminal is preferably ADV_SCAN_IND in which a flag indicating the third child terminal 18c is set in the message, for example.

Here, since the example in which the first child terminal 18a and the second child terminal 18b approach the vehicle 2 is given, the third child terminal 18c does not exist around the vehicle 2. Therefore, even if the selection unit 37 transmits the existence confirmation advertisement Ad4 for the third child terminal, the selection unit 37 cannot receive a response (scan request) to the transmission. Therefore, the selection unit 37 recognizes that the third child terminal 18c does not exist in the communication area E2 around the vehicle because the response to the existence confirmation advertisement Ad4 for the third child terminal cannot be received.

In step 116, after the scanning of the terminals 3 existing around the vehicle 2 is completed, the selection unit 37 selects the terminal 3 to be the communication partner from these terminals 3. In the case of this example, the selection unit 37 confirms the connection priority information Dt distributed from the server 16 and registered in the wireless authentication device 7, and identifies the terminal 3 having the highest communication priority. Here, since an example in which the first child terminal 18a and the second child terminal 18b exist around the vehicle 2, the first child terminal 18a having a high connection priority is selected as the communication partner.

In step 117, the selection unit 37 outputs a request for issuing the communication connection advertisement Ae1 for the first child terminal to the communication unit 9 as the communication connection advertisement Ae for requesting the communication connection from the terminal 3.

In step 118, when the communication unit 9 receives the issuance request of the communication connection advertisement Ae1 for the first child terminal from the selection unit 37, the communication unit 9 transmits the communication connection advertisement Ae1 for the first child terminal as the communication connection advertisement Ae. The communication connection advertisement Ae1 for the first child terminal is preferably ADV_IND in which a flag indicating the first child terminal 18a is set in the message, for example.

In step 119, when the first child terminal 18a receives the communication connection advertisement Ae1 for the first child terminal, which is the communication connection advertisement Ae for itself, the first child terminal 18a transmits a connect request to the vehicle 2 as a response to the communication connection advertisement Ae1. In the case of this example, since the first child terminal 18a is located in the communication area E1 near the vehicle 2, the received signal strength when receiving the communication connection advertisement Ae becomes equal to or higher than the reception threshold value and is connected. The operation of returning the request to the vehicle 2 can be executed.

In step 120, when the communication unit 9 receives the connect request from the first child terminal 18a, it outputs the connect request to the selection unit 37. The selection unit 37 recognizes that short-range wireless communication may be connected to the first child terminal 18a when a connect request is input in response to the issuance request of the communication connection advertisement Ae1 for the first child terminal.

In step 121, the wireless authentication device 7 shifts the short-range wireless communication with the first child terminal 18a to the state of communication connection. As a result, short-range wireless communication can be executed between the first child terminal 18a and the wireless authentication device 7.

The communication connection advertisement Ae1 may be transmitted a plurality of times during a predetermined time. In this way, for example, even if the terminal 3 located far from the wireless authentication device 7 is selected as the selection target, the terminal 3 waits for the terminal 3 to approach the wireless authentication device 7 and connects the communication with the terminal 3. can do.

When the short-range wireless communication with the wireless authentication device 7 of the vehicle 2 shifts to the state of communication connection, the first child terminal 18a executes the authentication of the key information Dk registered in itself. At this time, the authentication unit 8 receives the key information Dk from the first child terminal 18a by short-range wireless communication, and confirms whether or not the key information Dk can be correctly decrypted. At the time of authentication of the key information Dk, if the key information Dk can be correctly decrypted, both the first child terminal 18a and the authentication unit 8 shift to the authentication completed state. Therefore, thereafter, various operations of the vehicle 2 such as locking / unlocking the vehicle door and transition operation of the vehicle power supply (engine starting operation) can be executed.

According to the communication connection destination selection system 22 of the above embodiment, the following effects can be obtained.
(1) The communication connection destination selection system 22 has a terminal 3 around the wireless authentication device 7 that authenticates the key information Dk registered in the terminal 3 by distribution from the outside by short-range wireless communication with the terminal 3. When there are a plurality of terminals 3, the terminal 3 to be connected to the communication is selected from among them. The communication connection destination selection system 22 includes a registration unit 32, a notification unit 36, and a selection unit 37. The registration unit 32 transmits the connection priority information Dt in which the connection priority order of the terminal 3 to the wireless authentication device 7 is set to the management device 23 via the network, and registers the connection priority information Dt in the management device 23. The notification unit 36 notifies the wireless authentication device 7 from the management device 23 of the connection priority information Dt registered in the management device 23 by network communication. When the terminal 3 and the wireless authentication device 7 communicate with each other, the selection unit 37 selects the terminal 3 to be the connection destination of the communication based on the connection priority information Dt notified from the management device 23.

According to the configuration of this example, even if a plurality of terminals 3 exist around the wireless authentication device 7, which terminal 3 is wirelessly authenticated through the determination using the connection priority information Dt provided by the management device 23. It is possible to set whether or not it should be the connection destination for the communication of the device 7. Therefore, the terminal 3 intended by the user among the plurality of terminals 3 can be set as the communication partner of the wireless authentication device 7.

(2) To register the connection priority information Dt, input the connection priority information Dt at the terminal 3 or the external device 33 owned by the owner of the article 1 (in this example, the vehicle 2) equipped with the wireless authentication device 7. This is a process of transmitting the connection priority information Dt to the management device 23 via the network. In this case, since only the legitimate owner can register the connection priority information Dt, it is possible to prevent the illegal registration of the connection priority information Dt from occurring.

(3) The selection unit 37 has the highest connection priority order based on the connection priority information Dt among the terminals 3 that have responded to the advertisement (in this example, the existence confirmation advertisement Ad) periodically transmitted from the wireless authentication device 7. The terminal 3 is selected, and the wireless authentication device 7 is allowed to communicate with the terminal 3. In this case, since it is possible to select the terminal 3 between the terminal 3 and the wireless authentication device 7 before shifting to the actual communication, when selecting the terminal 3 to be connected to the communication of the wireless authentication device 7. , It doesn't take time.

(4) When a third party attempts to illegally connect his / her own terminal 3 to the wireless authentication device 7, for example, this terminal 3 receives an advertisement (existence confirmation advertisement Ad) and returns a response to the wireless authentication device 7. Is likely to be repeated many times. Therefore, when the response to the advertisement is repeated many times, the wireless authentication device 7 may forcibly block the communication to ensure the security of the communication.

In addition, this embodiment can be implemented by changing as follows. The present embodiment and the following modified examples can be implemented in combination with each other within a technically consistent range.
