Description

Parts information display system and management device

[0001] The technology disclosed in this specification relates to a system and device for displaying information about components mounted by a component mounter.

[0002] A component mounter is provided with multiple component supply units capable of supplying components. The component supply units are, for example, feeders. The feeders are set in set positions called slots. The feeders set in the slots are equipped with reels containing multiple components, and supply the components from the reels to the component mounter. Conventionally, a system that manages component mounters displays status information on a display device for each component supply unit, indicating the number of components remaining in that unit. By viewing this display, workers can recognize the status of each component supply unit, such as whether it is out of components, nearly out of components, or has enough components remaining, and then replenish components in each component supply unit as necessary.

[0003] Japanese Patent Laid-Open Publication No. 5-335795 discloses an electronic component insertion machine that, when it detects an out-of-component condition during component supply, moves an out-of-component sensor to detect the out-of-component conditions of other components across the entire component supply section, and displays the out-of-component detection result on a display unit.

[0004] Conventionally, status information was displayed for each component supply unit. Furthermore, among the multiple component supply units, there may be multiple component supply units that supply the same type of parts. Conventionally, when an operator wanted to view the status information for each of the multiple component supply units that supply the same type of parts, the operator had to scroll or perform other operations on the display device to check the status information for each unit, which was cumbersome.

[0005] In addition, in the past, when a worker realized that one of multiple component supply units supplying the same type of part was out of parts, they would replenish the part without checking the status information of another component supply unit supplying the same type of part, resulting in an increase in parts in progress. "Parts in progress" refers to parts that have been opened from an unused, properly stored state. This specification presents a technology useful for solving at least one of these problems.

[0006] This specification discloses a component information display system including a management device capable of acquiring status information for each component supply unit, the status information including at least the number of remaining components in each of a plurality of component supply units arranged to be able to supply components to a component mounter, and a display device, and the management device causes the display device to display aggregated status information that aggregates the status information of a first component supply unit that is one of the component supply units and the status information of one or more second component supply units that are different from the first component supply unit and that supply the same type of components as the first component supply unit.

[0007] According to the above configuration, consolidated status information that aggregates the status information of the first component supply unit and the second component supply unit that supply the same type of parts is displayed on the display device. This allows the worker to visually check the consolidated information of the status information of the first component supply unit and the second component supply unit without performing complicated operations. Furthermore, by viewing the consolidated status information, the worker can appropriately determine whether parts replenishment is necessary, thereby preventing the unnecessary accumulation of parts in process.

[0009] The main features of the embodiments described below are listed below. Note that the technical elements described below are independent technical elements that exhibit technical utility either alone or in various combinations, and are not limited to the combinations described in the claims at the time of filing.

[0010] In the part information display system disclosed in this specification, the aggregated status information may include a total remaining part number obtained by adding together the remaining part numbers at the first part supply unit and the second part supply unit. With this configuration, by viewing the aggregated status information, a worker can recognize the total remaining part number of the first part supply unit and the second part supply unit.

[0011] In the part information display system disclosed in this specification, the aggregated status information may include information indicating the degree of out-of-stock status based on a total number of remaining parts, which is the sum of the number of remaining parts at the first part supply unit and the number of remaining parts at the second part supply unit. With this configuration, by viewing the aggregated status information, a worker can accurately recognize the degree of out-of-stock status of parts of the same type that can be supplied by each of the first part supply unit and the second part supply unit.

[0012] In the component information display system disclosed in this specification, the aggregated status information may include a product production time by the component mounter based on a total number of remaining components, which is the sum of the number of remaining components in the first component supply unit and the number of remaining components in the second component supply unit. With this configuration, by viewing the aggregated status information, a worker can accurately recognize how much time remains to produce a product using the same type of components that can be supplied by each of the first component supply unit and the second component supply unit.

[0013] In the part information display system disclosed in this specification, the consolidated status information may include a plurality of identification information fields indicating identification information associated with each of the first and second part supply units. The management device may vary the display mode of the identification information fields on the display device depending on the remaining number of parts in the part supply unit corresponding to each of the identification information. With this configuration, a worker can intuitively recognize the status of each of the first and second part supply units by looking at each identification information list in the consolidated status information.

[0014] In the part information display system disclosed in this specification, the management device may change the overall display mode of the aggregated status information on the display device depending on a total number of remaining parts, which is the sum of the number of remaining parts at the first part supply unit and the number of remaining parts at the second part supply unit. With this configuration, by looking at the aggregated status information, a worker can intuitively recognize the result of aggregating the status information of the first part supply unit and the second part supply unit.

[0015] In the component information display system disclosed in this specification, the management device may be configured to display the aggregated status information on the display device when simultaneous pickup of components from the first component supply unit and the second component supply unit by a single predetermined pickup operation by a head mounted on the component mounter and having multiple suction nozzles is not possible. Furthermore, when simultaneous pickup is possible, the management device may be configured to display the status information of the first component supply unit and the status information of the second component supply unit in a differentiated manner on the display device. According to this configuration, the management device can determine whether or not to display the aggregated status information depending on whether simultaneous pickup is possible or not.

[0016] The category of the technology disclosed in this specification is not limited to component information display systems. According to this specification, for example, individual devices constituting the system and methods executed by the system and the individual devices can be understood. For example, a management device includes an information acquisition unit that acquires status information for each of a plurality of component supply units arranged to be able to supply components to a component mounter, the status information including at least the number of remaining components in each of the component supply units, and a display control unit that displays, on a predetermined display device, aggregated status information that aggregates the status information of a first component supply unit that is one of the component supply units and the status information of one or more second component supply units that are different from the first component supply unit and supply the same type of components as the first component supply unit.

[0017] The embodiments will be described with reference to the drawings. Each drawing is merely an example, and the present embodiment is not limited to the contents shown in the drawings. Also, since each drawing is an example, some parts may be omitted.

[0018] FIG. 1 schematically illustrates a component mounting system 1 according to this embodiment. At least a portion of the component mounting system 1 corresponds to a component information display system 2. The component mounting system 1 includes, for example, a management device 10, one or more component mounters 20, and one or more terminals 30. The component mounter 20 is a device capable of mounting components supplied from multiple component supply units onto a board. The component mounter 20 is also referred to as a chip mounter, a surface mounter, etc. The component mounter 20 illustrated in FIG. 1 may be understood as one component mounter included in a component mounting line configured with multiple substrate-related operating machines lined up side by side. The component mounter 20 has a display device 21.

[0019] The management device 10 is a computer capable of managing and controlling each substrate-related operation machine that makes up the component mounting line. The management device 10 may be mainly composed of a single computer, or may be composed of multiple computers connected to each other so as to be able to communicate with each other. This specification describes the functions of the management device 10 that are necessary for this embodiment among the various functions of the management device 10. The terminal 30 is, for example, a computer that each worker holds and operates. The computer assumed in this embodiment may be a computer of any type, such as a desktop computer, laptop computer, or tablet computer, or may be a smartphone or other mobile computer.

[0020] The management device 10 includes a control unit 11, a memory unit 12, a communication IF 13, a display unit 14, and an operation reception unit 15. IF is an abbreviation for interface. The control unit 11 has a processor such as a CPU and a memory, and functions as an information acquisition unit 16a, a display control unit 16b, etc. by the processor executing arithmetic processing in accordance with a program 16 stored in the memory, etc. The memory unit 12 stores various data and programs required by the control unit 11. The memory unit 12 is composed of a storage medium. At least a portion of the memory possessed by the control unit 11 may be considered to be the memory unit 12.

[0021] The communication IF 13 is a general term for an IF that allows the management device 10 to communicate with the mounters 20, the terminal 30, and other communication devices via wired and / or wireless connections. In other words, the management device 10 can communicate with the mounters 20 and the terminal 30. In this embodiment, there is no particular restriction on the standard or protocol used for communication between the devices.

[0022] The display unit 14 is a means for displaying visual information. The display unit 14 may be considered an example of a "display device" that displays the aggregated status information in this embodiment. Similarly, the display device 21 of the component mounter 20 or the display unit 31 of the terminal 30 also corresponds to an example of a display device that displays the aggregated status information. The component information display system 2 includes the management device 10 and such a display device. Of course, there may be multiple display devices. The operation reception unit 15 is a means for receiving operations by the worker, such as a keyboard, a mouse, switches, etc. If the display unit 14 also functions as a touch panel, the display unit 14 also corresponds to an example of the operation reception unit 15.

[0023] 2 shows a simplified view from above of the internal configuration of the component mounter 20. The component mounter 20 is equipped with a head 22 that is movable along mutually orthogonal X- and Y-axes. The drive mechanism for moving the head 22 is not shown. The head 22 is a rotary head that can rotate around the central Z-axis. It has multiple suction nozzles 23 spaced at regular angular intervals along its circumference. Each small circle within the head 22 indicates the position of the multiple suction nozzles 23 that the head 22 has.

[0024] In FIG. 2 , the rectangular object designated by reference numeral 40 is the circuit board 40. Furthermore, each rectangular object designated by reference numeral 24 represents a plurality of feeders 24 arranged so as to be able to supply components to the mounter 20. The feeders 24 correspond to an example of a "component supply unit." In the example of FIG. 2 , the plurality of feeders 24 are lined up along the X-axis direction. Although details are omitted, each feeder 24 is equipped with a reel containing a plurality of components, and supplies the components by feeding the reel along the Y-axis direction. The dashed rectangle drawn on each feeder 24 indicates the component supply position P by the respective feeder 24.

[0025] Each feeder 24 is set in a single set position called a slot, and sequentially supplies components of the same type. In this embodiment, multiple feeders 24 can also supply the same types of components. These multiple feeders 24 may be considered to be part of the mounter 20, or may be considered to be a mechanism attached to the mounter 20 from the outside.

[0026] The head 22 picks up components supplied to each supply position P by each feeder 24 by using each suction nozzle 23. After picking up the components using the suction nozzles 23, the head 22 moves toward the board 40, for example, via above the part camera 25. As the head 22 moves above the part camera 25, the part camera 25 captures images of each component picked up by each suction nozzle 23 from below. Although details are omitted, the images captured by the part camera 25 are used to correct misalignment of the components with respect to their mounting positions on the board 40, which is caused by misalignment of the components with respect to the suction nozzles 23.

[0027] On the board 40, the head 22 moves to each specified mounting position Q and mounts the corresponding component at each mounting position Q. Then, when the mounting of the component that was picked up by the suction nozzle 23 is completed, the head 22 returns to the supply position P of the feeder 24 and repeats the same movement to mount the component on the next board 40.

[0028] 3 is a flowchart showing the component information display process executed by the control unit 11 of the management device 10 in accordance with the program 16. The information acquisition unit 16a of the control unit 11 acquires status information for each feeder 24 (step S100). The status information for each feeder 24 includes at least the number of remaining components in each of the multiple feeders 24 arranged for the component mounter 20. In other words, the information acquisition unit 16a acquires the status information for each feeder 24 by communicating with the component mounter 20 via the communication IF 13.

[0029] The number of remaining components in each feeder 24 changes as needed depending on the progress of the component mounting process on the board 40 by the mounter 20. For example, a predetermined controller installed in the mounter 20 monitors the number of remaining components in each feeder 24 and transmits status information including the number of remaining components as a result of the monitoring to the management device 10 at a predetermined frequency. In addition to the number of remaining components, the status information may also include, for example, identification information for each feeder 24, the type of component, information indicating the degree of component shortage depending on the number of remaining components, and the product production time depending on the number of remaining components.

[0030] In step S110, the display control unit 16b of the control unit 11 generates aggregated status information that aggregates status information of a first feeder, which is one of the multiple feeders 24, and status information of one or more second feeders, which are different from the first feeder and supply the same type of parts as the first feeder. Then, in step S120, the display control unit 16b displays the aggregated status information generated in step S110 on a predetermined display device. The display control unit 16b may also display information other than the aggregated status information on the display device along with the aggregated status information. The first feeder is an example of a "first parts supply unit," and the second feeder is an example of a "second parts supply unit." The control unit 11 repeatedly executes the flowchart of FIG. 3 and causes the display device to display the latest aggregated status information at that time.

[0031] The information other than the aggregated status information is not particularly limited as long as it is visual information that can be displayed by the display device. For example, for a feeder 24 that is neither a first feeder nor a second feeder, that is, for a feeder 24 that does not have any other feeders 24 that supply the same type of parts, the display control unit 16b displays status information for each feeder 24. Therefore, in step S120, the display control unit 16b can also simultaneously display the aggregated status information for the first and second feeders and the status information for another feeder 24 on the display device.

[0032] 4 shows an example of the aggregated status information 50 displayed on the display device in step S120. The aggregated status information 50 is displayed, for example, on the display device 21. The aggregated status information 50 includes various information such as slot number, part type, part status, total remaining part quantity, and product production time. A slot number is a number assigned to each slot, and for example, consecutive numbers are assigned to each slot lined up along the X-axis in the order of arrangement. As described above, one feeder 24 is set in one slot, and therefore the slot number can also be considered a type of identification information for each feeder 24 set in the slot. However, the identification information for each feeder 24 is not limited to the slot number, as long as it can be recognized by a worker as information for identifying the feeder 24.

[0033] 4, the aggregated status information 50 is information that aggregates the status information of the feeder 24 with slot number 1, the feeder 24 with slot number 4, and the feeder 24 with slot number 5. In other words, the aggregated status information 50 is information that is generated and displayed because the three feeders 24 with slot numbers 1, 4, and 5 are feeders 24 that each supply the same type of component, "BA." Therefore, in the example of FIG. 4, any one of the three feeders 24 with slot numbers 1, 4, and 5 corresponds to the first feeder, and the other three feeders 24 other than the first feeder correspond to the second feeders.

[0034] The control unit 11 treats, for example, the feeder 24 corresponding to the original slot as the first feeder. The original slot refers to a slot that is most suitable as a supply location for a certain type of component in terms of efficiency, such as the movement time and movement distance of the head 22, during component mounting processing by the mounter 20. In other words, the head 22 receives supply of a certain type of component from the feeder 24 corresponding to the original slot, and when the remaining number of components in the feeder 24 corresponding to the original slot reaches zero, the head 22 receives supply from a second feeder that can supply the same type of component. The control unit 11 may receive instructions from the mounter 20 regarding which is the original slot for each component type, or the control unit 11 may know this information internally. Note that slots that do not correspond to the original slots in terms of efficiency, as described above, are also referred to as next slots.

[0035] For example, if the slot with slot number 1 is the original slot for a component of component type "BA," then in Figure 4, the feeder 24 with slot number 1 corresponds to the first feeder, and the feeders 24 with slot numbers 4 and 5 correspond to the second feeders. However, in this embodiment, it is not necessary to treat the feeder 24 corresponding to the original slot as the first feeder. For example, if the component currently being mounted by the head 22 is being supplied from the feeder 24 corresponding to the next slot, the feeder 24 corresponding to the next slot may be treated as the first feeder.

[0036] 4, the total remaining part quantity "10050" included in the consolidated status information 50 is an example of the total remaining part quantity obtained by adding up the remaining part quantities in the first feeder and the second feeder. In other words, it can be seen that the total remaining part quantity of the part type "BA" in each of the feeders 24 with slot numbers 1, 4, and 5 is currently 10050.

[0037] The component status included in the aggregated status information 50 is an example of information indicating the degree of component shortage based on the total component remaining count, which is the sum of the component remaining counts in the first feeder and the second feeder. As shown in FIG. 4 , the component status "Components Setup Complete" is displayed based on the total component remaining count of "10050." "Components Setup Complete" indicates that the total component remaining count is sufficient and therefore no component replenishment is necessary. Various other component statuses, such as "Components Out of Stock Notice" and "Out of Component," can also be displayed to indicate the degree of component shortage. "Components Out of Stock Notice" is a component status when the total component remaining count is below a predetermined threshold and is displayed to prompt the operator to replenish components. "Out of Component" is a component status when the total component remaining count is zero and represents the highest level of urgency.

[0038] The product production time included in the aggregated status information 50 is an example of the product production time by the mounter 20 based on the total number of remaining components, which is the sum of the number of remaining components in the first feeder and the number of remaining components in the second feeder. As shown in FIG. 4 , a product production time of "201" is displayed based on the total number of remaining components, which is "10,050." The unit of product production time is minutes here. This indicates that product production by the mounter 20 will continue for 201 minutes from the current time, when the total number of remaining components of component type "BA" is 10,050. Note that the product production time does not necessarily need to be an exact time; it may be a predicted value. The display control unit 16b may determine the component status and product production time based on the total number of remaining components, a predetermined threshold, rules regarding product production time, and the like. The display control unit 16b generates this aggregated status information 50 and displays it on the display device.

[0039] According to this embodiment, the management device 10 displays on the display device aggregated status information that aggregates the status information of a first component supply unit, which is one of the multiple component supply units, and the status information of one or more second component supply units that supply the same types of parts as the parts supplied by the first component supply unit. The effects of this embodiment will be described below based on a comparison with a conventional example.

[0040] FIG. 8 is an example of a conventional display, showing a list display 60 of status information for each feeder 24. Conventionally, a specific display device has displayed the component type, component status, remaining component quantity, and product production time for each slot number, i.e., for each feeder 24. In other words, conventionally, the displayed component status, remaining component quantity, and product production time were information for each feeder 24. As shown in FIG. 8 , the status information for feeders 24 with a component status of "out of components," which has the highest level of urgency, is preferentially displayed at the top of the list display 60. Therefore, in some cases, the limited display area of ​​the display device is occupied by the "out of components" status information, making it difficult for the operator to recognize the overall status, including feeders 24 in other states such as "out of components warning" and "completion of components."

[0041] According to this embodiment, the aggregated status information allows the operator to recognize the overall situation for a certain type of part, including not only feeders 24 that are "out of parts" but also feeders 24 that are in other states such as "out of parts notice" or "parts set complete." Furthermore, according to this embodiment, it is possible to simultaneously display on the display device not only aggregated status information 50 for parts of part type "BA," but also aggregated status information for each of various parts such as part types "BB" and "BC."

[0042] Furthermore, according to the conventional system, the status information for each of the different feeders 24 supplying the same type of component is displayed in different locations in the list display 60, which requires the operator to scroll or otherwise check each status information, which is cumbersome. Furthermore, the operator may overlook part of the status information for each of the different feeders 24 supplying the same type of component, resulting in unnecessary component supply. In the example of FIG. 8 , while looking at the display corresponding to slot number 1, the operator may overlook the display corresponding to slot number 5, resulting in the supply of component type "BA" to slot number 1 even though there are sufficient components of this type in the feeder 24 of slot number 5. Similarly, while looking at the display corresponding to slot number 2, the operator may overlook the display corresponding to slot number 6, resulting in the supply of component type "BB" to slot number 2. This results in an increase in in-process components for component types "BA" and "BB."

[0043] On the other hand, according to this embodiment, the aggregated status information is presented to the worker. Therefore, the worker can appropriately determine whether or not to replenish parts without performing complicated operations or overlooking anything. As a result, unnecessary accumulation of parts in process is avoided.

[0044] Several modified examples included in this embodiment will be described. Each modified example can also be combined. First modified example: The aggregated status information 50 includes multiple identification information fields indicating the identification information associated with each of the first and second feeders. FIG. 5 is a diagram for explaining the first modified example, and shows the aggregated status information 50 in the same manner as FIG. 4.

[0045] In Figure 5, the slot number columns 51, 52, and 53 in the aggregated status information 50 indicate slot numbers 1, 4, and 5, respectively. As described above, the slot number can be considered identification information for each feeder 24 set in the slot, so the slot number columns 51, 52, and 53 can be considered examples of multiple identification information columns. The management device 10 changes the display mode of the identification information columns on the display device depending on the number of remaining parts in the feeder 24 corresponding to each identification information. Changing the display mode means, for example, using different colors. In Figure 5, the slot number columns 51, 52, and 53 are represented by different colors depending on the density of the hatching.

[0046] 8, according to the status information for the feeder 24 with slot number 1, the remaining number of components is 0. Furthermore, according to the status information for the feeder 24 with slot number 4, the remaining number of components is 50, and according to the status information for the feeder 24 with slot number 5, the remaining number of components is 10,000. Such remaining number of components for each feeder 24 was acquired in step S100. Therefore, in step S120, the display control unit 16b displays, for example, the slot number column 51 indicating slot number 1 in red according to the remaining number of components for each of the feeders 24 with slot numbers 1, 4, and 5. Furthermore, for example, the slot number column 52 indicating slot number 4 in yellow, and the slot number column 53 indicating slot number 5 in green.

[0047] According to this first modification, the worker can intuitively recognize the status of the first feeder and each second feeder by looking at each slot number column 51, 52, 53 in the consolidated status information 50. Varying the display mode may include not only different colors but also different patterns or different light-emitting patterns such as blinking. The correspondence between the display mode, such as color, applied to the identification information column and the number of remaining parts in feeder 24 is determined in advance.

[0048] Second Modification: FIG. 6 is a diagram illustrating a second modification, showing the aggregated status information 50 in the same manner as FIG. 4 . The management device 10 may vary the overall display mode of the aggregated status information 50 on the display device depending on the total number of remaining parts, which is the sum of the number of remaining parts in the first feeder and the number of remaining parts in the second feeder. According to FIG. 6 , the total number of remaining parts is 10,050. In this case, in step S120, the display control unit 16b displays all lists showing the contents of each item, such as slot number, part type, part status, total number of remaining parts, and product production time, in green, for example. If the total number of remaining parts is equal to or less than a predetermined threshold, the display control unit 16b can display all such lists in yellow, for example, or if the total number of remaining parts is zero, in red, for example. According to this second modification, by viewing the aggregated status information 50, a worker can intuitively recognize the result of aggregating the status information of the first and second feeders.

[0049] Third Modification: The head 22 having multiple suction nozzles 23 may be capable of "simultaneous suction" in which components are picked up from both the first feeder and the second feeder in a single predetermined suction operation. More specifically, simultaneous suction refers to, for example, an operation in which the movement of the head 22 along the X-axis and Y-axis is stopped or only limited, small movements are allowed, and components are picked up from multiple supply positions P by the rotation of the head 22 and the suction operation of each suction nozzle 23. Therefore, in this specification, it is assumed that simultaneous suction of components from the first feeder and the second feeder can be performed when the first feeder and the second feeder are arranged consecutively along the X-axis direction.

[0050] 4, 5, and 6, the feeder 24 with slot number 1 is the first feeder, the two feeders 24 with slot numbers 4 and 5 are the second feeders, and between them are feeders 24 with slot numbers 2 and 3. Therefore, these first and second feeders are not contiguous along the X-axis direction. Therefore, simultaneous pickup is not applicable to these feeders 24 that supply component type "BA."

[0051] On the other hand, if the three feeders 24 with slot numbers 1, 2, and 3 correspond to the first and second feeders that supply the component type "BA," then these three feeders 24 are all contiguous along the X-axis direction, and it is determined that simultaneous pickup is possible for these feeders 24 that supply the component type "BA."

[0052] 7 is a flowchart showing the component information display process according to the third modified example. Differences between FIG. 7 and FIG. 3 will be described below. After step S100, in step S105, the control unit 11 of the management device 10 determines whether the head 22 is capable of simultaneous pickup of a certain component (e.g., a component of component type "BA") as described above. The determination in step S105 can be made, for example, based on the relationship between the slot number and component type included in the status information for each feeder 24.

[0053] If the control unit 11 determines that simultaneous pickup is not possible, it proceeds from "No" in step S105 to step S110. On the other hand, if it determines that simultaneous pickup is possible, it proceeds from "Yes" in step S105 to step S130. In other words, if simultaneous pickup of components from both the first feeder and the second feeder in a single predetermined pickup operation is not possible, the management device 10 displays the aggregated status information 50 on the display device. On the other hand, if such simultaneous pickup is possible, in step S130, the management device 10 displays the status information for the first feeder and the status information for the second feeder separately on the display device. Step S130 is a process of displaying the status information for each feeder 24 in a list format, as shown in FIG. 8.

[0054] When the heads 22 are unable to simultaneously pick up a certain type of component, the travel distance required for the heads 22 to pick up the component from the first or second feeder and carry it to the board 40 becomes longer than when simultaneous pick-up is possible, which tends to increase the overall cycle time. Therefore, in the third modified example, when simultaneous pick-up is not possible, the management device 10 displays aggregated status information 50 to encourage the worker to replenish components at the optimal time, thereby achieving the effect of reducing in-process parts. On the other hand, when simultaneous pick-up is possible, the effect of shortening the cycle time takes priority over the effect of reducing in-process parts, and the display of status information for each feeder 24 encourages the worker to quickly replenish components for each feeder 24.

[0055] The component supply unit capable of supplying components to the mounter 20 is not limited to the feeder 24. The component supply unit may be, for example, a tray. The management device 10 may be understood as a type of controller mounted on the mounter 20. In other words, this specification includes embodiments in which the mounter 20, which includes the management device 10 as a part thereof, executes the flowcharts shown in FIGS. 3 and 7 .

[0056] Although specific examples of the technology disclosed in this specification have been described in detail above, these are merely examples and do not limit the scope of the claims. The technology described in the claims includes various modifications and variations of the specific examples exemplified above. Furthermore, the technical elements described in this specification or drawings exhibit technical utility alone or in various combinations, and are not limited to the combinations described in the claims at the time of filing. Furthermore, the technology exemplified in this specification or drawings simultaneously achieves multiple objectives, and achieving one of those objectives itself has technical utility.
