DETAILED DESCRIPTION

Overview

(9) Fulfillment centers may be used to fulfill online purchases and other orders. For example, fulfillment centers may include product inventory that may be pulled when an order for a particular product or multiple products is placed. In some instances, the product(s) may be packed and shipped from the fulfillment center. However, the process of obtaining the product(s), packing the product(s), and shipping the product(s) may be complicated due to the amount of inventory, the number of orders to process, the size of the fulfillment center, and/or other factors. In addition, a portion of the fulfillment center designated for packing or shipping may be different than the portion of the fulfillment center designated for holding product inventory. As a result, transportation of products in an order may be time consuming.

(10) Moving items or objects through a fulfillment center may require handling of the item itself. For example, picking the item from inventory, placing the item into a container, removing the item from a container, and so forth may all be examples of actions for which an item may need to be handled. In addition, different items may have different types of packaging. For example, some items may come in boxes, some items may come in loose bags, some items may come shrink wrapped, some items may not have any packaging, and so forth. Humans may be able to manually handle individual items with ease. However, robotic handling of individual items may require various levels of dexterity. Moreover, fulfillment centers may include lengthy conveyors that may be used to transport objects, such as packages, products, items, or other objects, as well as containers that may be at least partially full of objects. Transport of containers or items (e.g., individual items or multiple items, etc.) may involve the use of container shuttles that move on one or more rails to transport a container from one location to another. For example, in some facilities, a container of items may be loaded onto a shuttle, and the shuttle may transport the container from an inventory field to a sortation system or other location.

(11) In a typical warehouse environment, such as that illustrated in FIG. 1, items may be transported through various means such as conveyors, belts, shuttles, etc. as they undergo different operations like picking, sorting, storing, shipping/dispatch, and so forth. In some of these cases, containers may be used to transport items, either individually or in groups, from one location to another. For instance, transporting items from a pick station to a sort station may involve the item(s) being picked into a container, such as a tote, which may then be transported via a shuttle. Shuttles may therefore move along a shuttle rail system or track that has a number of curves or turns.

(12) Embodiments of the disclosure include shuttles having dynamic wheel assemblies that allow the shuttles to turn or otherwise move along curves and/or turns of the track or rail system with decreased risk of damage and increased longevity. Shuttles may be powered by electromagnet propulsion systems, and the dynamic wheel assemblies may passively move or rotate to facilitate movement of the shuttle along the track or rail system. Shuttles may be used to transport the one or more items from a first location to a second location.

(13) As a result of the improve functionality provided by the shuttle movement systems described herein, flexibility and throughput of the processing of items at the fulfillment center may be increased, such as by streamlining an induction process. Some embodiments include optimized process flows for processing of orders at fulfillment centers, as well as process flows or methods to increase speed of consolidating products in a multi-item order as a result of improved speed in transportation of items and/or containers. As a result, throughput of fulfillment centers may be improved, and/or logistics of fulfillment center operations may be less complicated.

(14) Referring to FIG. 1, an example use case 100 for dynamic wheel assemblies for shuttles powered by linear synchronous motors is depicted in accordance with one or more embodiments of the disclosure. Although discussed in the context of online orders, other embodiments may be directed to any suitable use case where containers or items are transported, such as instances where objects are picked from inventory, placed into containers, containers or items are transported, and so forth.

(15) In FIG. 1, a fulfillment center may be a traditional fulfillment center and may include an inventory field 110, a routing sorter 160, one or more item sorting machines 170, and one or more packing stations 180. The inventory field 110 may include a storage platform, or a portion of the fulfillment center at which products picked from product inventory are placed. Robots may be used to pick products from inventory and to deliver to the robotic storage platform in some instances, while in other instances, manual labor or a combination thereof may be used to pick products. The picking process at the robotic storage platform may include locating a product in an order, obtaining the product, and sending the product to a robotic storage platform, such as via a conveyor belt. In the illustrated embodiment, products at the robotic storage platform may be placed in a container, such as a tote.

(16) The inventory field 110 may include multiple items that are in inventory. The items may be used to fulfill orders. The inventory field 110 may be a robotic field in some instances. One or more picking stations 130 may be positioned along a perimeter 120 of the inventory field 110. The picking stations 130 may be manually operated or may include robotic components, or a combination thereof. In some instances, picking of items from the inventory field 110 may be completed by robots that include automated robotic arms, where the items are delivered to the picking stations 130 after being retrieved from the inventory field 110. Any number of picking stations 130 may be included, and the picking stations 130 may be located in a different position than that illustrated in FIG. 1.

(17) In a traditional fulfillment center, such as that illustrated in FIG. 1, one or more conveyors 150 may be disposed about the inventory field 110. For example, conveyors 150 may be disposed along the perimeter 120 of the inventory field 110. The conveyors 150 may run adjacent to the picking stations 130 in some embodiments. Any suitable conveyor configuration may be used. In the illustrated example, the conveyors 150 may include belts or rollers that run alongside the picking stations 130 and include one or more paths to one or more routing sorters.

(18) The conveyors 150 may be used to transport one or more containers, such as totes 140. For example, as totes 140 move along the conveyors 150, items may be moved from the picking stations 130 into respective totes 140. The totes 140 may be associated with particular item sorting machines, and may be moved using the conveyors 150 to a routing sorter 160. In contrast, embodiments of the disclosure may not include some or all of the conveyors 150, and instead may include rails that may be used to guide shuttles from one location to another.

(19) The routing sorter 160 may be configured to route, divert, or otherwise guide certain totes to an item sorting machine. The routing sorter 160 may include any combination of ramps, slides, rollers, arms, guides, and/or other components to route totes to a particular item sorting machine. At the routing sorter 160, totes including products that have been picked may be routed to the appropriate or designated item sorting machine. For example, the routing sorter 160 may determine an identifier associated with the tote, and may determine an item sorting machine associated with the tote using the identifier. The routing sorter 160 may route or direct the tote to the appropriate item sorting machine.

(20) A number of item sorting machines 170 may be coupled to the routing sorter 160. For example, a first item sorting machine 172, a second item sorting machine 174, a third item sorting machine 176, and so forth may be coupled to the routing sorter 160. The routing sorter 160 may optionally guide totes to the item sorting machines to which they are assigned. For example, a first tote 162 may include item 1, item 16, and item 23, and may be assigned to the first item sorting machine 172. The routing sorter 160 may therefore route the first tote 162 to the first item sorting machine 172 for sortation of the respective items. A second tote 164 may include item 1656, and may be assigned to the second item sorting machine 174. The routing sorter 160 may therefore route the second tote 164 to the second item sorting machine 174 for sortation of the item. A third tote 166 may include item 989, item 145, and item 34, and may be assigned to the third item sorting machine 176. The routing sorter 160 may therefore route the third tote 166 to the third item sorting machine 176 for sortation of the respective items.

(21) Some or all of the item sorting machines may be associated with one or more packing stations 180 that may be used to pack items into a shipment when a multi-item order is complete. For example, the first item sorting machine 172 may be coupled to a first packing station 182, the second item sorting machine 174 may be coupled to a second packing station 184, the third item sorting machine 176 may be coupled to a third packing station 186, and so forth. The item sorting machines may be configured to receive items from totes that have one or more, or multiple, items. The number of totes and/or the number of items associated with respective item sorting machines may be balanced, and multiple totes may be routed to the first item sorting machine 172 and the second item sorting machine 174 at the same time.

(22) At any of the stages of the example fulfillment process of FIG. 1 where handling of items and/or containers by shuttles, or actively managed shuttle movement, occurs, systems as described herein may be used for dynamic wheel assemblies for shuttles powered by linear synchronous motors.

(23) Embodiments of the disclosure include systems and methods for dynamic wheel assemblies for shuttles powered by linear synchronous motors. Certain embodiments may improve processing speed and/or throughput of fulfillment centers. Certain embodiments may improve performance of mechanical equipment for sortation and/or consolidation of items. While described in the context of online orders, aspects of this disclosure are more broadly applicable to other forms of object handling.

(24) Example embodiments of the disclosure provide a number of technical features or technical effects. For example, in accordance with example embodiments of the disclosure, certain embodiments of the disclosure may improve processing speed, throughput, and/or efficiency of fulfillment centers. The above examples of technical features and/or technical effects of example embodiments of the disclosure are merely illustrative and not exhaustive.

(25) One or more illustrative embodiments of the disclosure have been described above. The above-described embodiments are merely illustrative of the scope of this disclosure and are not intended to be limiting in any way. Accordingly, variations, modifications, and equivalents of the embodiments disclosed herein are also within the scope of this disclosure. The above-described embodiments and additional and/or alternative embodiments of the disclosure will be described in detail hereinafter through reference to the accompanying drawings.

Illustrative Embodiments and Use Cases

(26) FIG. 2 is a schematic illustration of an example use case 200 and facility layout for dynamic wheel assemblies for shuttles powered by linear synchronous motors in accordance with one or more embodiments of the disclosure. Other embodiments may include additional or fewer components. The illustration of FIG. 2 may not be to scale, and may not be illustrated to scale with respect to other figures.

(27) In FIG. 2, a fulfillment center may include an inventory field 210, at which products or other items may be stored in inventory. As the items are ordered in online orders, the products may be picked from the inventory field 210 and routed for downstream processing in the fulfillment center. The items may be picked manually, using robots, vehicles, or a combination thereof.

(28) The picked products may be placed into one or more containers and the items may be removed from the containers and inducted onto one or more shuttles for transport, such as one or more shuttles on rails 220. The shuttles on rails 220 may include shuttles that are configured to transport items without containers from one location to another via rails. The rails may include switching rail components that allow for the shuttles to move from one set of rails to another. Other embodiments may include electromagnets configured to pull shuttles in certain directions and/or along curves or turns. The shuttles on rails 220 may transport containers from the inventory field 210 to one or more downstream processes, such as a sortation system 230, or a packing system 240. For example, the sortation system 230 may be a system at which items picked from the inventory field 210 may be re-sorted into respective totes or other containers for particular orders. For example, items for different orders may be placed into containers that are transported by the shuttles on rails 220 from the inventory field 210. The containers may be sent to the sortation system 230 for sorting into particular orders. The packing system 240 may be a station at which one or more items associated with an order may be packed into a box or other container for shipment. A shipping label may be applied and the package may be dispatched to a loading dock or elsewhere for shipment. Other destinations or downstream processes in addition to, or instead of, the sortation systems and packing systems may be used.

(29) A rail system 260 is depicted in schematic view in FIG. 2. The rail system 260 is an example of a network of rails that may be used by shuttles to transport containers from one location to another. The network of rails may include locations at which a shuttle can be directed to a straight path or to a loop, turn, oval, circle, and/or other geometries that involve a change in direction of a shuttle on the rails. Such changes in direction may be implemented using switching rail components and/or electromagnets. The rail system 260 may include rails that link various systems, such as sortation systems, to each other and/or to other systems, such as container handling systems, manual induction systems 290, and so forth. For example, the rail system 260 may link a first sortation system 270 to a second sortation system 272, as well as to a first container handling system 280, a second container handling system 282, a third container handling system 284, and so forth. The rail system 260 may be used to connect any of the systems to each other and/or other systems.

(30) Shuttles may move along the rails of the rail system 260. The shuttles may include linear drive motors or other drive components. Some drive components may provide a drive force via electromagnetism. As a result, one or more electromagnets may be disposed along the network of rails. Shuttles may optionally include a conveyor surface, such as a belt, that may have a first set of one or more raised flaps and a second set of one or more raised flaps. The first set of raised flaps may form a first barrier along a first open-ended side of the shuttle, and the second set of raised flaps may form a second barrier along a second open-ended side of the shuttle to prevent items rolling off the conveyor belt. The shuttles may include an onboard drive motor configured to move the conveyor belt in a forward direction and/or a reverse direction. The shuttles may include a magnet disposed on a lower surface of the shuttle. The magnet may be used to propel and/or secure the shuttle. For example, the magnet may prevent the shuttle from moving while the vehicle is in motion and the linear drive motor is engaged. To onboard or offload containers, the linear drive motor of the shuttle or other component may be used in conjunction with the magnet to impart motion.

(31) FIG. 3 is a schematic illustration of a perspective view and a close-up view of a shuttle rail system 300 in accordance with one or more embodiments of the disclosure. Other embodiments may include additional or fewer components. The illustration of FIG. 3 is not to scale, and may not be illustrated to scale with respect to other figures. The system illustrated in FIG. 3 may be used with the shuttles discussed with respect to FIGS. 1-2, and/or may be used with any of the systems described herein.

(32) The shuttle rail system 300 may be configured to provide continuous rail for switching the direction of a shuttle 350 in an electromagnetically propelled shuttle-on-rail arrangement. Shuttle-on-rail arrangements may be used in many systems, such as sortation systems, pick systems, delivery systems, etc. The shuttle rail system 300 may include rail switch mechanisms to allow the rail to be directed to alternate path. Shuttle-rail arrangements that are based on electromagnetic propulsion, such as linear drive motors, may have sets of electromagnets arranged along the direction of the rails. Shuttles may also have a magnet, such as a permanent magnet, coupled to a lower side of the shuttle. The electromagnet and the permanent magnet may have to be separated by a very narrow gap for optimal performance. Such factors may be impacted by the weight of the payload on the shuttles, which may be increased due to a container weight. Such issues may be avoided by embodiments of the disclosure, where shuttles can move more smoothly along the rail system 300.

(33) The shuttle rail system 300 may include a first branched path 310, where if shuttles were moving along the shuttle rail system 300 in a clockwise direction, the shuttle could move in either a straight direction along the oval path of the shuttle rail system 300, or may make a left-handed curve onto a separate path of the shuttle rail system 300. Similarly, a second branched path 320 may allow for merging of shuttles that took a left curve at the first branched path 310 to merge back onto the oval path of the shuttle rail system 300. Any number of curved path and straight path intersections may be included in the shuttle rail system 300. For example, the shuttle rail system 300 may include a third branched path 330 and a fourth branched path 340. The shuttle rail system 300 may form a closed loop track in some embodiments.

(34) An induction path may be connected to the shuttle rail system 300 and may be accessible via the shuttle rail system 300. For example, the shuttle 350 moving along the shuttle rail system 300 is depicted positioned along an induction path, where an operator may induct items onto the shuttle 350 for transport. An example induction portion 370 is depicted in close-up view 360, where items can be removed from a tote or other container and deposited onto a shuttle by an operator or a robotic manipulator during an item induction process. Example positioning for shuttle movement systems as described herein may include positioning at induction stations and/or packing stations.

(35) FIG. 4 is a schematic illustration of various views of an induction station and a shuttle rail system in accordance with one or more example embodiments of the disclosure. Other embodiments may include additional or fewer components. The illustration of FIG. 4 is not to scale, and may not be illustrated to scale with respect to other figures. The induction station illustrated in FIG. 4 is depicted solely for illustrative purposes. Other types of stations may be used. The shuttle and shuttle rail system of FIG. 4 may be the same shuttle and shuttle rail system discussed with respect to FIGS. 1-3.

(36) In FIG. 4, a system 400 with a right-handed induction station 440 is depicted. The induction station 440 may be disposed adjacent to a track 410 and a conveyor 420. An operator may retrieve items from a container 430 on the conveyor 420 and place the items onto a shuttle 446. The induction station 440 may include an overhead support 444 and a display 442 configured to present a user interface. A light curtain 448 may provide additional safety for an operator. An operator at the induction station 440 may be right-handed and may perform the induction process ergonomically. The conveyor 420 may be disposed adjacent to the induction station, where the conveyor is configured to transport the item to the induction station (e.g., with or without a conveyor). If the induction station is a right-handed induction station, the conveyor 420 may be disposed at a left side of the induction station.

(37) Also depicted in FIG. 4 is a system 450 with a left-handed induction station 440. The induction station 440 may be disposed adjacent to a track 410 and a conveyor 420. An operator may retrieve items from a container 430 on the conveyor 420 and place the items onto a shuttle 446. The induction station 440 may include an overhead support 444 and a display 442 configured to present a user interface. A light curtain 448 may provide additional safety for an operator. An operator at the induction station 440 may be left-handed and may perform the induction process ergonomically. The conveyor 420 may be disposed adjacent to the induction station, where the conveyor is configured to transport the item to the induction station (e.g., with or without a conveyor). If the induction station is a left-handed induction station, the conveyor 420 may be disposed at a right side of the induction station.

(38) FIG. 5 is a schematic illustration of various curved portions of a shuttle track in accordance with one or more example embodiments of the disclosure. Other embodiments may include additional or fewer components. The illustration of FIG. 5 is not to scale, and may not be illustrated to scale with respect to other figures.

(39) In FIG. 5, a system 500 depicts a shuttle rail system 510 that forms a track along which shuttles 520 can move. The shuttles may be propelled along the track via one or more electromagnets, such as a first electromagnet 530, a second electromagnet 532, and so forth. The shuttle 520 may include the frame and other components discussed with respect to FIGS. 6A-6B, which may allow the shuttle to move along curves or turns of the tracks with improved smoothness and reduced likelihood of damage and wear. For example, the shuttle rail system 510 may include a first curve 512, a second curve 514, and so forth.

(40) The shuttle rail system 510 may have a track having a central axis, the track having a first rail segment 516 on a first side of the central axis and a second rail segment 518 on a second side of the central axis. The shuttle 520 may be configured to transport one or more items using the track.

(41) The shuttle 520 may include one or more permanent magnets configured to interact with electromagnets 530, 532 to move along the track. The shuttle 520 may include a first conveyor assembly optionally having a central axis that is transverse to the central axis of the track. The shuttle 520 may include a frame having an H-shaped configuration with a front lateral portion, a rear lateral portion, and a central member disposed between the front lateral portion and the rear lateral portion. The shuttle 520 may include a first wheel assembly coupled to a first end of the front lateral portion, the first wheel assembly having one or more wheels, such as a first plurality of wheels, configured to engage a sidewall of the first rail segment 516, where the first wheel assembly is configured to rotate in a forward and rearward direction with respect to the front lateral portion.

The shuttle 520 may be configured to support the one or more items on the first conveyor assembly.

(42) FIGS. 6A-6B are schematic illustrations of a portion of a shuttle 600 in accordance with one or more embodiments of the disclosure. Other embodiments may include additional or fewer components. The illustrations of FIGS. 6A-6B are not to scale, and may not be illustrated to scale with respect to other figures. The shuttles illustrated in FIGS. 6A-6B may be the same shuttles and used with the same shuttle rail systems discussed with respect to FIGS. 1-5.

(43) In FIG. 6A, a portion of the shuttle 600 is depicted in a bottom view. The shuttle may have a frame 602 having an H-shape configuration. The shuttle 600 may include one or more wheel assemblies. For example, the shuttle 600 may include a first wheel assembly 610 adjacent to a first corner of the shuttle 600, a second wheel assembly 620 adjacent to a second corner of the shuttle 600, a third wheel assembly 630 adjacent to a third corner of the shuttle 600, and/or a fourth wheel assembly 640 adjacent to a fourth corner of the shuttle 600. The wheel assemblies may be configured to move, pivot, or rotate with respect to the frame 602. For example, the wheel assemblies may be configured to rotate or move in both forward and rear directions with respect to the frame 602. As a result, the shuttle 600 may be able to slide along curves and/or turns more smoothly. The wheel assemblies may include horizontally oriented wheels to engage sidewalls of the track and provide additional stability and/or smoother movement along curved portions of the track.

(44) The shuttle 600 may be configured to move along a track. The shuttle 600 may include the frame 602. The frame 602 may have a front lateral portion 604, a rear lateral portion 606, and a central member 608 disposed between the front lateral portion 604 and the rear lateral portion 606. The central member 608 may be arranged perpendicular to the front lateral portion 604 and the rear lateral portion 606, and may therefore have an H-shaped configuration.

(45) The first wheel assembly 610 may be coupled to a first end of the front lateral portion 604. The first wheel assembly 610 may include a first wheel 612 and a second wheel 614 configured to engage a first sidewall of the track, where the first wheel assembly 610 may be configured to rotate in a forward and rearward direction with respect to the front lateral portion 604. The first wheel assembly 610 may include one or more vertically oriented wheels configured to move along the track, such as a third wheel 616. Any number of vertical or horizontal wheels may be included.

(46) The second wheel assembly 620 coupled to a second end of the rear lateral portion 606. The second wheel assembly 620 may include a first wheel 622 and a second wheel 624 configured to engage a second sidewall of the track, where the second wheel assembly 620 may be configured to rotate in a forward and rearward direction with respect to the rear lateral portion 606. The first end and the second end may therefore be on opposite sides of the shuttle 600. The second wheel assembly 620 may include one or more vertically oriented wheels configured to move along the track, such as a third wheel 626. Any number of vertical or horizontal wheels may be included.

(47) The third wheel assembly 630 may be coupled to a second end of the front lateral portion 604. The third wheel assembly 630 may include a first wheel 632 and a second wheel 634 configured to engage the second sidewall of the track, where the third wheel assembly 630 can be configured to rotate in the forward and rearward direction with respect to the front lateral portion 606. The third wheel assembly 630 may include one or more vertically oriented wheels configured to move along the track, such as a third wheel 636. Any number of vertical or horizontal wheels may be included.

(48) The fourth wheel assembly 640 may be coupled to a first end of the rear lateral portion 606. The fourth wheel assembly 640 may include a first wheel 642 and a second wheel 644 configured to engage the first sidewall of the track, where the fourth wheel assembly 640 can be configured to rotate in the forward and rearward direction with respect to the rear lateral portion. The fourth wheel assembly 640 may include one or more vertically oriented wheels configured to move along the track, such as a third wheel 646. Any number of vertical or horizontal wheels may be included.

(49) In FIG. 6B, the portion of the shuttle 600 is depicted in an upper perspective view. As depicted in FIG. 6B, the wheel assemblies may be the same. Other embodiments may have different wheel assembly configurations. The first wheel assembly 610 may include a frame portion 650 configured to rotate with respect to the frame 602 of the shuttle 600. The frame portion 650 may be configured to rotate in the forward and rearward direction with respect to the front lateral portion 604. The frame portion 650 may have a geometry having a first triangular shaped side 652 and a second triangular shaped side 654, so as to avoid contacting the sides of the tracks during rotation or movement. Other geometries may be used.

(50) The first wheel assembly 610 may include a ferrous block 660 disposed at a side, such as an outer-facing side, of the first wheel assembly 610. The ferrous block 660 may be used to interact with electromagnets and direct the shuttle 600 in a certain direction. The first wheel assembly may include the first wheel 612 disposed on a first side of the ferrous block 660, and the second wheel 614 disposed on a second side of the ferrous block 660. The first wheel 612 and the second wheel 614 may have a horizontal orientation. The third wheel may have a vertical orientation and may therefore be a vertically oriented wheel configured to roll along the track. The ferrous block 660 may have one or more beveled surfaces disposed along edge surfaces of the ferrous block 660. For example, the ferrous block 660 may have a first beveled edge 664 at a first lower corner and a second beveled edge 666 at a second lower corner. The beveled edges 664, 666 may improve an electromagnetic-based steering performance of the shuttle 600 and may also increase lateral stability of the first wheel assembly 610. Any number of beveled surfaces may be included.

(51) The shuttle 600 may include additional features that may interact with track-based features to increase functionality. For example, some or all of the wheel assemblies may include flag components that may trigger track-based features, such as shuttle identification, turn indications, and other features.

(52) In one example, the first wheel assembly 610 may include a first flag component 670 that may be configured to interact with a first electromagnetic switch disposed along the track. Similarly, the second wheel assembly 620 may also include a second flag component 680 that is configured to interact with a second electromagnetic switch disposed along the track. Including flag components on both sides of the shuttle 600 may allow for increased functionality depending on corresponding track feature placement.

(53) The flags 670, 680 may be disposed on an upper side of the respective ferrous blocks. For example, the first flag 670 may be disposed on top or on an upper side of the ferrous block 660. The first flag 670 may have an L-shaped cross-sectional geometry and may be formed of metal or another material. The ferrous block 660 may have a concave planar contour along an outer surface 662 to increase a strength of interaction with external electromagnets. A bolt 690 may be disposed through the ferrous block 660 and the third wheel 616 to increase rigidity of the wheel assembly and prevent buckling of the third wheel 616 during turns or curves.

(88) Another example programming language may be a higher-level programming language that may be portable across multiple architectures. A software component comprising higher-level programming language instructions may require conversion to an intermediate representation by an interpreter or a compiler prior to execution.

(89) Other examples of programming languages include, but are not limited to, a macro language, a shell or command language, a job control language, a script language, a database query or search language, or a report writing language. In one or more example embodiments, a software component comprising instructions in one of the foregoing examples of programming languages may be executed directly by an operating system or other software component without having to be first transformed into another form.

(90) A software component may be stored as a file or other data storage construct. Software components of a similar type or functionally related may be stored together such as, for example, in a particular directory, folder, or library. Software components may be static (e.g., pre-established or fixed) or dynamic (e.g., created or modified at the time of execution).

(91) Software components may invoke or be invoked by other software components through any of a wide variety of mechanisms. Invoked or invoking software components may comprise other custom-developed application software, operating system functionality (e.g., device drivers, data storage (e.g., file management) routines, other common routines and services, etc.), or third-party software components (e.g., middleware, encryption, or other security software, database management software, file transfer or other network communication software, mathematical or statistical software, image processing software, and format translation software).

(92) Software components associated with a particular solution or system may reside and be executed on a single platform or may be distributed across multiple platforms. The multiple platforms may be associated with more than one hardware vendor, underlying chip technology, or operating system. Furthermore, software components associated with a particular solution or system may be initially written in one or more programming languages, but may invoke software components written in another programming language.

(93) Computer-executable program instructions may be loaded onto a special-purpose computer or other particular machine, a processor, or other programmable data processing apparatus to produce a particular machine, such that execution of the instructions on the computer, processor, or other programmable data processing apparatus causes one or more functions or operations specified in the flow diagrams to be performed. These computer program instructions may also be stored in a computer-readable storage medium (CRSM) that upon execution may direct a computer or other programmable data processing apparatus to function in a particular manner, such that the instructions stored in the computer-readable storage medium produce an article of manufacture including instruction means that implement one or more functions or operations specified in the flow diagrams. The computer program instructions may also be loaded onto a computer or other programmable data processing apparatus to cause a series of operational elements or steps to be performed on the computer or other programmable apparatus to produce a computer-implemented process.

(94) Additional types of CRSM that may be present in any of the devices described herein may include, but are not limited to, programmable random access memory (PRAM), SRAM, DRAM, RAM, ROM, electrically erasable programmable read-only memory (EEPROM), flash memory or other memory technology, compact disc read-only memory (CD-ROM), digital versatile disc (DVD) or other optical storage, magnetic cassettes, magnetic tape, magnetic disk storage or other magnetic storage devices, or any other medium which can be used to store the information and which can be accessed. Combinations of any of the above are also included within the scope of CRSM. Alternatively, computer-readable communication media (CRCM) may include computer-readable instructions, program module(s), or other data transmitted within a data signal, such as a carrier wave, or other transmission. However, as used herein, CRSM does not include CRCM.

(95) Although embodiments have been described in language specific to structural features and/or methodological acts, it is to be understood that the disclosure is not necessarily limited to the specific features or acts described. Rather, the specific features and acts are disclosed as illustrative forms of implementing the embodiments. Conditional language, such as, among others, can, could, might, or may, unless specifically stated otherwise, or otherwise understood within the context as used, is generally intended to convey that certain embodiments could include, while other embodiments do not include, certain features, elements, and/or steps. Thus, such conditional language is not generally intended to imply that features, elements, and/or steps are in any way required for one or more embodiments or that one or more embodiments necessarily include logic for deciding, with or without user input or prompting, whether these features, elements, and/or steps are included or are to be performed in any particular embodiment.
