[0075] <Comparative Example>

[0076] As a comparative example, Patent Document 1 (Technical Solution 1) describes the following: “A battery type determination device comprising: an output control unit that instructs a current application circuit to apply a specific current to a target battery; a voltage response measurement unit that measures a voltage response of the target battery to the current applied by the output control unit; and a calculation unit that calculates an inductance value of the target battery based on a current value applied by the output control unit and a voltage value measured by the voltage response measurement unit;

[0077] and a determination unit that determines the type of the target battery based on a specified value of the inductance corresponding to the type of the target battery and the inductance value of the target battery obtained by the calculation unit. ".

[0078] Patent document 2 (technical solution 1) states the following, namely, "A battery management system comprising: a first management device, which manages a plurality of batteries that can be mounted on a mobile body powered by the battery by associating battery characteristics measured under specified conditions with identification information of each battery; and a second management device, which, when a first battery mounted on the mobile body is replaced with a second battery, compares the battery characteristics of the second battery measured under the specified conditions in the mobile body with the battery characteristics associated with the identification information of the second battery in the first management device, and prohibits the use of the second battery in the mobile body if the comparison fails."

[0079] However, regarding the structure involved in the comparative example, in the case where the battery is improperly replaced during the rental of a battery-powered vehicle, etc., there is room for improvement in effectively detecting the improper battery replacement. For example, the secondary battery installed in the xEV accounts for a large part of the cost of the vehicle body. Therefore, there is a risk of replacing it with an informal product of inferior quality. In particular, xEVs used for rental and leasing purposes are often used by multiple unspecified people different from the owner, and the risk of informal products mixing in is relatively high. In order to quickly grasp this situation, the purpose of the present disclosure is to provide a highly versatile system for identifying the type of vehicle-mounted secondary batteries and making authenticity determinations.

[0080] <Implementation Method>

[0081] Hereinafter, an embodiment of the present disclosure will be described with reference to the accompanying drawings. In each of the drawings, the same reference numerals are used for parts having the same structure or function. In the description of this embodiment, repeated descriptions of the same parts may be appropriately omitted or simplified.

[0082] Figure 1 1 is a diagram showing an overview of a determination system 1a according to one embodiment. The determination system 1a determines the authenticity of a battery 41 mounted on a vehicle 40. The vehicle 40 is an electric vehicle driven by the electric energy of the battery 41. The vehicle 40 may include, for example, a BEV (Battery Electric Vehicle), an HEV (Hybrid Electric Vehicle), and a PHEV (Plugin Hybrid Electric Vehicle) (these electric vehicles are collectively referred to as "xEV").

[0083] The determination system 1a includes an information processing device 10, a camera 21, a physical property sensor 22, and a vehicle information DB (Database) 30. Hereinafter, the determination systems 1a, 1b, and 1c are sometimes collectively referred to as "determination system 1". The information processing device 10 is connected to the camera 21, the physical property sensor 22, and the vehicle information DB (Database) 30 in a communicable manner.

[0084] The camera 21 takes a picture of the vehicle 40 and acquires an image. The camera 21 may be, for example, a digital camera. The image is used to acquire information required to identify the vehicle 40, such as the vehicle body number, vehicle model, manufacturer, model (era), grade, and license plate information. The camera 21 may acquire, for example, one or more images including a license plate, a portion recording the vehicle body number of the vehicle 40, and an appearance capable of distinguishing the vehicle body shape of the vehicle 40. The camera 21 may acquire not only an image of the vehicle 40, but also a written image such as a driving license recording information required to identify the vehicle 40.

[0085] The physical property sensor 22 measures the physical property of the battery 41 (target battery) mounted on the vehicle 40. The physical property sensor 22 is, for example, a magnetic sensor that measures the leakage magnetic flux formed around the battery 41, but is not limited to this. For example, the physical property sensor 22 may be an ultrasonic sensor, a current sensor, or the like. In addition, the physical property sensor 22 may be, for example, a sensor that can measure the current characteristics or changes in the external magnetic field accompanying the charging and discharging of the battery 41, the sound wave reflection characteristics derived from the structure of the battery 41, or the internal solvent material of the battery 41 and its distribution.

[0086] The vehicle information DB 30 stores the correspondence between the vehicle ID (vehicle identification information) for identifying the vehicle 40 and the battery ID (battery identification information) for identifying the battery 41. Figure 1 In the example of , the vehicle information DB 30 not only shows the correspondence between the vehicle ID and the battery ID, but also shows the correspondence between the vehicle model and the battery type. Figure 1 In the embodiment, the vehicle information DB 30 is provided outside the information processing device 10, but at least a part of the functions of the vehicle information DB 30 may be provided in the information processing device 10. The vehicle information DB 30 may be provided by a plurality of DBs (for example, referring to Figure 3 and Figure 7 The vehicle DB 121 (121a, 121b) and the battery DB 123 (123a, 123b) described later are configured.

[0087] The information processing device 10 determines the authenticity of the battery 41 mounted on the vehicle 40. The information processing device 10 is a computer such as a PC (Personal Computer), a WS (Workstation) or a tablet terminal. The information processing device 10 has an analyzing unit 101 and a comparing unit 102. The analyzing unit 101 analyzes the image acquired by the camera 21 and the physical properties of the battery 41 measured by the physical property sensor 22. The comparing unit 102 compares the battery ID corresponding to the vehicle ID acquired by analyzing the image and the battery ID acquired by analyzing the physical properties of the battery 41 to determine the authenticity of the battery 41. As described later, the analyzing unit 101 and the comparing unit 102 can be implemented by software.

[0088] With regard to the above-described structure, the information processing device 10 acquires a vehicle ID for identifying the vehicle 40 based on analysis of an image acquired by the camera 21 and input of information for identifying the vehicle 40 from a user. The information processing device 10 obtains a first battery ID (first battery identification information) for identifying the battery 41 corresponding to the acquired vehicle ID, with reference to the vehicle information DB 30, etc. The information processing device 10 acquires the physical properties of the battery 41 mounted on the vehicle 40, and acquires a second battery ID (second battery identification information) for identifying the battery 41 corresponding to the acquired physical properties, with reference to the vehicle information DB 30, etc. The information processing device 10 compares the first battery ID and the second battery ID, determines the authenticity of the battery 41 mounted on the vehicle 40, and outputs the result of the determination of the authenticity of the battery 41.

[0089] Thus, the determination system 1 compares the battery ID corresponding to the vehicle ID for identifying the vehicle 40 with the battery ID determined based on the physical properties of the battery 41 to determine the authenticity of the battery 41. Therefore, the determination system 1 can effectively determine whether the battery 41 mounted on the vehicle 40 has been replaced illegally.

[0090] Figure 2 Yes means Figure 1 The information processing device 10 is a block diagram of a configuration example of an information processing device 10.

[0092] The storage unit 12 includes, for example, any storage component such as a HDD (Hard Disk Drive), an SSD (Solid State Drive), a ROM (Read-Only Memory), and a RAM (Random Access Memory). The storage unit 12 can function as, for example, a main storage device, an auxiliary storage device, or a cache. The storage unit 12 stores any information used for the operation of the information processing device 10. For example, the storage unit 12 can store system programs, application programs, and various information received through the communication unit 13. The storage unit 12 is not limited to being built into the information processing device 10, and can also be an external database or an external storage component. For example, the storage unit 12 can store images acquired by the camera 21 and measured values ​​of physical properties acquired by the physical property sensor 22.

[0093] The communication unit 13 includes any communication component that can communicate with other devices such as scanners through any communication technology. The communication unit 13 may also include a communication control component for controlling communication with other devices, and a storage component for storing communication data such as identification information required for communication with other devices. For example, the communication unit 13 can communicate with the camera 21, the physical property sensor 22, and the vehicle information DB 30.

[0094] The input unit 14 includes one or more input interfaces for accepting input operations of the operator and obtaining input information based on the operator's operations. For example, the input unit 14 is a physical key, a capacitive key, a pointing device, a touch screen integrated with the display of the output unit 15, or a microphone for accepting voice input, but is not limited thereto.

[0095] The output unit 15 includes one or more output interfaces for outputting information to the operator and notifying the operator. For example, the output unit 15 is a display that outputs information as an image, or a speaker that outputs information in the form of voice, but is not limited thereto. Such a display can be, for example, a liquid crystal panel display or an organic EL (ElectroLuminescence) display. In addition, at least one of the input unit 14 and the output unit 15 can be integrally formed with the information processing device 10, or can be separately provided.

[0096] The functions of the information processing device 10 (such as the analysis unit 101 and the comparison unit 102) can be realized by executing the computer program (program) involved in the present embodiment by the processor included in the control unit 11. That is, the functions of the information processing device 10 can be realized by software. The computer program enables the computer to implement the functions corresponding to the processing of each step by causing the computer to execute the processing of the steps included in the action of the information processing device 10. That is, the computer program is a program for causing the computer to function as the information processing device 10 involved in the present embodiment. The computer program can be recorded in a recording medium that can be read by the computer. The program contains information for use in the processing of the electronic computer and is information based on the program. For example, data that is not a direct instruction to the computer but has the nature of specifying the processing of the computer is equivalent to "information based on the program."

[0097] A part or all of the functions of the information processing device 10 may be realized by a dedicated circuit included in the control unit 11. That is, a part or all of the functions of the information processing device 10 may be realized by hardware. In addition, the information processing device 10 may be realized by a single computer or by the coordinated operation of a plurality of computers.

[0098] Figure 3 1 is a diagram showing a configuration example of a determination system 1b according to an embodiment. As described above, at least a part of the functions of the vehicle information DB 30 may be provided in the information processing device 10a. Figure 3 In the determination system 1b, the vehicle information DB 30 is provided in the comparison unit 102a of the information processing device 10a as the vehicle DB 121a and the battery DB 123a. Figure 3 In the example, the information processing device 10a includes an analyzing unit 101a and a comparing unit 102a. The analyzing unit 101a includes a vehicle number acquiring unit 111, a vehicle model acquiring unit 112, and a feature quantity acquiring unit 113. The comparing unit 102a includes a vehicle DB 121a, a vehicle ID specifying unit 122, a battery DB 123a, a battery ID specifying unit 124, and a determining unit 125.

[0099] The vehicle number acquisition unit 111 analyzes the image acquired by the camera 21 to acquire the vehicle number of the vehicle 40. Specifically, the vehicle number acquisition unit 111 can analyze a captured image of a driving license having the vehicle number recorded thereon or a captured image of a part of the vehicle 40 having the vehicle number engraved thereon to acquire the vehicle number.

[0100] The vehicle model acquisition unit 112 analyzes the image acquired by the camera 21 to acquire the vehicle model of the vehicle 40. Specifically, the vehicle model acquisition unit 112 may obtain the type of a car such as an ordinary sedan or a small truck as the vehicle model of the vehicle 40. The vehicle model acquisition unit 112 may analyze the image of the appearance of the vehicle 40, such as the appearance, the vehicle logo, and the driving license, to acquire the vehicle model. In addition, the vehicle model may include information such as the model (year), grade, and manufacturer.

[0101] In addition, the analysis unit 101a can obtain specific information for identifying the vehicle 40 other than the vehicle body number and vehicle model based on the image acquired by the camera 21. For example, the analysis unit 101a can analyze the image of the vehicle 40 taken by the camera 21, and extract the number string and character string in the license plate as specific information. Alternatively, the analysis unit 101a can obtain information such as the model (era) and grade as specific information. In addition, the analysis unit 101a can also obtain information for identifying the vehicle 40 not based on the image acquired by the camera 21. For example, the information processing device 10a can be connected to the OBD (On Board Diagnostics) of the vehicle 40 using an interface or a scanning tool, and obtain information for identifying the vehicle 40 from the OBD. Refer to Figure 7 As described later, the information processing device 10 a can accept input of information for specifying the vehicle 40 from a user.

[0102] In addition, when the vehicle body number, vehicle model, or other specific information of the vehicle 40 cannot be obtained based on the image of the camera 21, the analysis unit 101a can issue an alarm to the user. Specifically, the analysis unit 101a can display an image indicating the failure to obtain the vehicle body number, vehicle model, or other specific information of the vehicle 40 on the display of the output unit 15, or output an alarm sound from the speaker of the output unit 15. In addition, when the vehicle body number, vehicle model, or other specific information of the vehicle 40 cannot be obtained, the analysis unit 101a can obtain an image again using the camera 21. When the analysis unit 101a obtains the image again, it can display a guide of the shooting method of the camera 21 for obtaining a better image on the display of the output unit 15.

[0103] Figure 4 This is a diagram schematically illustrating an example of measuring the physical properties of the battery 41 . Figure 4 4 shows the horizontal plane of the bottom surface of the vehicle 40 viewed from below the plumb bob. Figure 4 As shown in the example, the battery 41 has cells 411 arranged in a grid pattern on a horizontal plane. Figure 4 In this way, the physical property sensor 22 can measure the magnetic flux while scanning the cell 411 in units of one row along the scanning direction 29 , thereby obtaining the spatial distribution of the magnetic flux formed around the cell 41 .

[0104] The feature quantity acquisition unit 113 acquires the feature quantity based on the measured value of the physical property of the battery 41 acquired by the physical property sensor 22. For example, when the feature quantity acquisition unit 113 acquires the measured value of the leakage magnetic flux formed around the battery 41, it can acquire information related to the spatial frequency and amplitude of the leakage magnetic flux as the feature quantity.

[0105] Vehicle DB 121a (refer to Figure 7 The vehicle DB 121 b described later is also the same) and is a database that indicates the correspondence between information for specifying the vehicle 40 , the vehicle ID, and the battery ID. Figure 5 This is a diagram showing an example of the vehicle DB 121 (121a, 121b).

[0106] exist Figure 5 In the above, the "manufacturer" is the manufacturer that manufactures the vehicle 40. The "model" is a classification of automobiles such as ordinary sedans and small trucks. The "type" is a classification index specified for automobiles with the same structure, device, and performance. For example, the "type" can be expressed as an identification mark marked with a combination of Latin letters and numbers in order to classify the model and model of the automobile.

[0107] The “lot number” is a number (serial number) assigned to each produced unit of the same specification vehicle 40. The “body number” is a unique identification number assigned to each vehicle 40 by the Ministry of Land, Infrastructure, Transport and Tourism upon application from the manufacturer of the vehicle 40.

[0108] The "vehicle ID" is identification information for uniquely identifying the vehicle 40 in the determination system 1. In the present embodiment, the "vehicle ID" is separate identification information different from other information such as the "vehicle body number" and the "batch number", but may be the same as other information such as the "vehicle body number" and the "batch number" or a combination thereof.

[0109] The "battery ID" is identification information for identifying the battery 41 mounted on the vehicle 40. In the present embodiment, the "battery ID" is separate information such as the serial number of the battery 41, but may be the same as other information such as the serial number or a combination thereof.

[0110] The vehicle ID identification unit 122 refers to the vehicle DB 121 a to acquire the vehicle ID and the battery ID corresponding to the specific information for identifying the vehicle 40 acquired by the vehicle body number acquisition unit 111 and the vehicle model acquisition unit 112 .

[0111] Battery DB123a (refer to Figure 7 The same also applies to the battery DB 123b described later, which is a database that represents the correspondence between feature quantities related to the physical properties of the battery 41 and the battery ID. Figure 6 This is a diagram showing an example of the battery DB 123 ( 123 a , 123 b ).

[0112] exist Figure 6 In the figure, the “magnetic waveform” is the magnetic field along Figure 4 The waveform of the magnetic space when the physical property sensor 22 is operated around the single body 411 in the scanning direction 29 .

[0113] The "feature quantity" is a value obtained by analyzing the measured value of the physical property sensor 22. For example, the "feature quantity" is information related to the spatial frequency and amplitude of the leakage magnetic flux. Figure 6 For example, T1, T2, and T3 are the spatial frequencies at which the peaks are observed. 2 is the square of the amplitude of the leakage flux.

[0114] The "battery type" is the type of the battery 41. For example, the "battery type" is a number (serial number) of the battery 41 assigned to each produced unit.

[0115] The "battery ID" is identification information for identifying the battery 41. In the present embodiment, the meaning of the "battery ID" on the vehicle DB 121 (121a, 121b) and the meaning of the "battery ID" on the battery DB 123 (123a, 123b) are the same.

[0116] The battery ID specifying unit 124 refers to the battery DB 123 a and acquires the battery ID corresponding to the feature quantity of the physical property of the battery 41 acquired by the feature quantity acquiring unit 113 .

[0117] The determination unit 125 compares the battery ID (first battery ID) associated with the vehicle 40 determined by the vehicle ID determination unit 122 with the battery ID (second battery ID) obtained based on the analysis of the physical properties of the battery 41 determined by the battery ID determination unit 124, and determines the authenticity of the battery 41. When the first battery ID and the second battery ID are consistent, the determination unit 125 determines that the battery 41 mounted on the vehicle 40 is authentic, and when not, determines that it is not authentic.

[0118] The information processing device 10a outputs the determination result of the determination unit 125. Figure 3 In the example of , the information processing device 10a causes the display unit 103 of the output unit 15 to display the result of the determination of the authenticity of the battery 41 and outputs the determination result.

[0119] In this embodiment, refer to Figure 3 Although each functional element described above is implemented by software, at least a part of the functional elements may be configured by dedicated hardware.

[0120] Reference Figure 1 and Figure 3 The configuration of the determination system 1 described above is an example, and various modifications are conceivable. Figure 7 1 is a diagram showing a configuration example of a determination system 1c according to an embodiment. In the determination system 1c, the analysis unit 101b includes a feature quantity acquisition unit 113. The comparison unit 102b includes a vehicle ID identification unit 122, a battery ID identification unit 124, and a determination unit 125.

[0121] Figure 7 The determination system 1c does not have the camera 21, but instead has an operation unit 23 for accepting operations from the user. The operation unit 23 may be constituted by the input unit 14. The determination system 1c allows the user to input specific information for identifying the vehicle 40, obtains the vehicle ID and battery ID corresponding to the input specific information, and outputs them to the determination unit 125.

[0122] The determination system 1c does not install the vehicle DB 121b and the battery DB 123b in the information processing device 10b but in a cloud or the like that can communicate with the information processing device 10b. The information processing device 10b accesses the vehicle DB 121b and the battery DB 123b via a network including the Internet or the like as needed.

[0123] The determination unit 125 compares the battery ID (first battery ID) associated with the specific information input by the user for identifying the vehicle 40 and the battery ID (second battery ID) associated with the characteristic quantity of the physical property of the battery 41 obtained by the physical property sensor 22. When the first battery ID and the second battery ID are consistent, the determination unit 125 determines that the battery 41 mounted on the vehicle 40 is authentic. Otherwise, it is determined to be not authentic. The determination unit 125 outputs the determination result to the recording unit 131. The recording unit 131 is an external storage device. The recording unit 131 can be, for example, a USB (Universal Serial Bus) memory or a network hard disk.

[0124] Figure 8 It is a flowchart showing an operation example of the determination system 1 . Figure 8 Yes means Figure 1 Flow chart of the operation of the information processing device 10. Figure 8 The operation of the information processing device 10 described above may correspond to one of the determination methods of the information processing device 10 . Figure 8 The actions of each step can be executed based on the control of the control unit 11 of the information processing device 10.

[0125] In step S1, the control unit 11 acquires a vehicle ID (vehicle identification information) for identifying the vehicle 40. Specifically, the control unit 11 may acquire the vehicle ID by analyzing an image captured of the vehicle 40 or by accepting input of specific information for identifying the vehicle 40 from a user.

[0126] In step S2, the control unit 11 acquires the first battery ID as identification information of the battery 41 corresponding to the vehicle ID acquired in step S1. Specifically, the control unit 11 may refer to the vehicle DB 121 (121a, 121b) to acquire the battery ID corresponding to the vehicle ID as the first battery ID.

[0127] In step S3, the control unit 11 acquires the physical properties of the target battery, which is the battery 41 mounted on the vehicle 40. Specifically, the control unit 11 controls the physical property sensor 22 to acquire the measured values ​​of the physical properties of the battery 41, such as the leakage magnetic flux.

[0128] In step S4, the control unit 11 obtains the second battery ID as identification information of the battery 41 corresponding to the physical property of the target battery (battery 41). Specifically, the control unit 11 can obtain the characteristic quantity of the physical property of the target battery, and obtain the battery ID corresponding to the characteristic quantity as the second battery ID by referring to the battery DB 123 (123a, 123b).

[0129] In step S5, the control unit 11 determines whether the first battery ID obtained in step S2 and the second battery ID obtained in step S4 are the same. If the first battery ID and the second battery ID are the same (YES in step S5), the control unit 11 advances the process to step S6, and if not (NO in step S5), the control unit 11 advances the process to step S7.

[0130] In step S6 , the control unit 11 determines that the battery 41 (target battery) mounted on the vehicle 40 is authentic.

[0131] In step S7 , the control unit 11 determines that the battery 41 (target battery) mounted on the vehicle 40 is not authentic.

[0132] In step S8, the control unit 11 outputs the determination result obtained in step S6 or step S7. Specifically, the control unit 11 may display the determination result of the authenticity of the target battery on the display unit 103 of the output unit 15, or output it to the storage unit 12 or the recording unit 131. If the process of step S8 is completed, the control unit 11 ends the process of the flowchart.

[0133] As described above, the information processing device 10 acquires the vehicle ID for identifying the vehicle 40, and acquires the first battery ID for identifying the battery 41 corresponding to the acquired vehicle ID. The information processing device 10 acquires the physical properties of the battery 41 mounted on the vehicle 40, and acquires the second battery ID for identifying the battery 41 corresponding to the acquired physical properties. The information processing device 10 compares the first battery ID and the second battery ID, determines the authenticity of the battery 41 mounted on the vehicle 40, and outputs the authenticity determination result.

[0134] In this way, the information processing device 10 compares the first battery ID corresponding to the vehicle ID with the second battery ID corresponding to the physical properties of the battery 41 to determine the authenticity of the battery 41 mounted on the vehicle 40. Therefore, the information processing device 10 can effectively determine whether the battery 41 mounted on the vehicle 40 has been replaced improperly.

[0135] In addition, the information processing device 10 can obtain an image of the vehicle 40 and obtain the vehicle ID based on the analysis result of the obtained image. In this way, the information processing device 10 obtains the vehicle ID based on the analysis result of the image of the vehicle 40 and determines the authenticity of the battery 41, so that it can effectively detect that the battery 41 has been replaced improperly from the vehicle 40.

[0136] In addition, the information processing device 10 may receive input of specific information for specifying the vehicle 40 from the user, and acquire the vehicle ID based on the specific information whose input is received.

[0137] In one embodiment, the information processing device 10 may obtain a measured value of a leakage magnetic flux of the battery 41 as a physical property of the battery 41. In this way, the information processing device 10 obtains the measured value of the leakage magnetic flux of the battery 41 to determine the authenticity of the battery 41, thereby making it difficult to improperly replace the battery 41 without revealing that the battery 41 is not authentic. Therefore, the information processing device 10 can effectively detect improper replacement of the battery 41.

[0138] As described above, the determination system 1 identifies the vehicle 40 using the camera 21 or the like, and obtains information for identifying the type and individual of the battery 41 that should have been mounted. On the other hand, the determination system 1 has a configuration that measures the physical properties of the battery 41 from the outside of the vehicle 40, thereby obtaining information for identifying the type and individual of the battery 41. The determination system 1 compares the first battery ID corresponding to the vehicle ID for identifying the vehicle 40 with the second battery ID corresponding to the physical properties of the battery 41, thereby detecting improper replacement of the battery 41.

[0139] In fact, when xEV is used as a business in the form of leasing or renting, the infrastructure varies according to each operator. In particular, it becomes a cost and operation issue to minimize the new investment for ensuring the safety of the battery 41 for each vehicle 40. Therefore, it is preferable to be able to use existing equipment, information and instruments.

[0140] The determination system 1 involved in the present disclosure is connected to existing equipment and instruments at low cost and with high versatility, and the structure of obtaining the battery ID according to the physical properties of the battery 41 and the structure of comparing the battery ID corresponding to the vehicle 40 to determine the authenticity of the battery 41 are independent. Therefore, according to the present disclosure, the information required for comparison and determination can be obtained from the outside, and the scalability can be ensured.

[0141] The present disclosure is not limited to the above-mentioned embodiments. For example, multiple modules recorded in the block diagram may be integrated, or one module may be divided. Multiple steps recorded in the flowchart may be executed in parallel or in a different order according to the processing capability of the device executing each step or as needed, instead of being executed in a time series according to the description. For example, in Figure 8 In the embodiment, the control unit 11 may perform the processing of step S1 and step S2 after performing the processing of step S3 and step S4. Alternatively, for example, the control unit 11 may perform the processing of step S2 and step S4 after performing the processing of step S1 and step S3. In addition, for example, the control unit 11 may perform the processing of step S3 and step S4 in parallel with the processing of step S1 and step S2. In addition, changes may be made within the scope of the subject matter of the present disclosure.
