Description

[Technical Field]

[0001] (CROSS-REFERENCE TO RELATED APPLICATIONS) This application claims priority to and the benefit of U.S. Patent Application No. 18 / 485,669, filed October 12, 2023, and U.S. Provisional Patent Application No. 63 / 477,612, filed January 27, 2023, each of which is incorporated herein by reference in its entirety. [Background technology]

[0002] In recent years, there has been a significant increase in the implementation of various types of batteries as alternatives to fossil fuels and other energy sources. Furthermore, the recent rise in popularity of electric vehicles and other electronic devices that include batteries has resulted in a significant increase in the demand for battery manufacturing, as well as an increase in the demand for the safe and efficient recycling or disposal of batteries and battery materials.

[0003] Despite advances in battery manufacturing and implementation in various fields of use, existing methods for the mass recycling and / or disposal of batteries and battery materials face several drawbacks. For example, conventional systems can safely recycle or dispose of batteries of a particular chemical composition, energy content, or form factor, such as, but not limited to, various types of lithium-ion batteries. However, certain compositions of batteries or devices are unstable and unsafe if handled improperly. Therefore, conventional methods for recovering batteries or devices from consumers often require trained handlers to receive and, in some cases, personally prepare each battery or device for safe transportation to a recycling facility. For example, conventional methods require trained handlers to tape the terminals of each battery and place each battery or device in a separate bag or container. In certain situations, consumers may be permitted to personally prepare batteries for storage and transportation by taping the terminals and / or placing individual batteries in designated containers. Furthermore, additional safety measures are generally required to ensure immediate response in the event of a thermal event caused by a discarded battery or device.

[0004] Therefore, various categories of batteries and devices must be handled, stored, and shipped with a high degree of care. Unfortunately, conventional methods of receiving and preparing batteries and devices for disposal or recycling generally require careful and extensive handling from trained handlers, resulting in an inefficient and often inconvenient process.

[0005] These, along with additional problems and challenges, exist with conventional systems for recovering batteries and devices. Summary of the Invention

[0006]

[0003] Embodiments of the present disclosure provide benefits and / or solve one or more of the aforementioned or other problems in the art with systems, apparatus, non-transitory computer-readable media, and methods for safely accepting, storing, and transporting batteries for disposal or recycling. For example, the disclosed system provides a convenient battery collection bin where consumers can safely deposit batteries by simply dropping one or more batteries or devices into the bin's chute without assistance from a trained associate. While maintaining the convenience of such operation, the disclosed system ensures the safe receipt, storage, and handling of deposited batteries by, for example, providing various options for intelligently automated distribution of fire suppressant onto deposited batteries or devices, and automated detection and response to thermal and / or chemical events.

[0007] In some embodiments, for example, an apparatus for retrieving batteries includes a bin or enclosure configured to receive and secure a transport drum for storing and transporting the loaded batteries and devices. The apparatus also includes a chute operable to direct the loaded batteries and devices into the transport drum when positioned within the enclosure or bin. Furthermore, in some embodiments, a removable fire suppressant cartridge is disposed above the transport drum and associated with a fire suppressant dispensing mechanism configured to selectively dispense fire suppressant from the fire suppressant cartridge into the transport drum when a battery is loaded therein via the chute. In one or more embodiments, the fire suppressant cartridge includes a jug or similar container filled with fire suppressant, which can be loaded into the interior of the bin or enclosure by attaching the jug to a receiving hatch of the apparatus. Additionally, in some embodiments, the apparatus further includes one or more sensors configured to determine one or more of the fill level, volume, or weight of the transport drum within the enclosure, the thermal characteristics within the enclosure, the carbon dioxide level within the enclosure, or the number of batteries or devices loaded into the transport drum within the enclosure. Additionally, in one or more embodiments, the apparatus includes additional safety measures such as, but not limited to, a blast plate configured to redirect impact blast from an explosion occurring within the enclosure or bin, and / or an emergency fire suppressant hatch configured to release available fire suppressant into the enclosure bin in response to high temperatures occurring therein.

[0008] Further, in some embodiments, the battery collection system receives signals from one or more sensors indicating the number of objects deposited into the battery collection bin and the fill level, volume, or weight of the battery collection bin. The battery collection system can also determine a quantity of fire suppressant based at least on the fill level, volume, or weight of the battery collection bin at the time the objects were deposited therein. In response, the battery collection system can dispense the determined quantity of fire suppressant from a fire suppressant cartridge or internal container (e.g., an internal hopper) and provide an indication of the number of objects deposited into the battery collection bin for display on a client device (e.g., on a local or remote device) associated with the battery collection bin.

[0009] Additionally, in some embodiments, the battery collection system, in response to receiving a signal indicating the fill level, volume, or weight of the battery collection bin, further determines that the fill level, volume, or weight has reached a threshold fill level, volume, or weight, and then provides an indication for display on a client device associated with the battery collection bin (e.g., on a local or remote device) that the threshold fill level, volume, or weight has been reached and locks one or more access doors to restrict access to and use of the battery collection bin. Also, in one or more embodiments, the battery collection system, in response to receiving a signal indicating the volume, weight, or fill level of fire suppressant available for dispersal, determines that the amount of fire suppressant available is below a threshold, and then provides an indication for display on a client device associated with the battery collection bin that there is insufficient fire suppressant available and / or locks one or more access doors to restrict access to the battery collection bin.

[0010] Thus, the disclosed embodiments offer significant advantages over existing solutions, such as the increased convenience and efficiency enabled by providing a battery collection bin for the safe disposal of batteries without assistance from trained associates or battery handlers, and without the need to tape, wrap, encase, or otherwise secure individual batteries to ensure safety during storage and transport. Furthermore, the disclosed embodiments represent an improvement in safety by eliminating the need for human interaction with potentially dangerous or unstable batteries and / or fire suppression materials to ensure safe handling, storage, and transport of batteries for disposal or recycling. Relatedly, the disclosed embodiments provide a safe and robust system for battery collection that can include additional features to prevent unwanted human interaction with the system, in some cases limiting user interaction to the disposal of individual batteries or devices.

[0011] Additional features and advantages of one or more embodiments of the present disclosure will be set forth in the description that follows, and in part will be obvious from the description, or may be learned by practice of such exemplary embodiments. [Brief explanation of the drawings]

[0013] This disclosure describes one or more embodiments of a battery collection system that provides a battery collection bin into which consumers can safely deposit batteries and devices for disposal or recycling without the assistance of a trained associate or handler. For example, in some embodiments, the battery collection system utilizes a battery collection bin to accept individual batteries and devices from consumers into a closed, monitored enclosure. Furthermore, in some embodiments, the battery collection system determines, based on the fill level, volume, or weight of the shipping drum at the time of battery deposit (or the detected size of the deposited batteries), an amount of fire suppressant to be sprayed over the deposited batteries to prevent a thermal event caused by, for example, an interaction between the batteries and / or devices within the shipping drum.

[0014] In some embodiments, for example, the battery classification system receives signals from one or more sensors indicating the number of objects deposited into the battery collection bin, the fill level, volume, and / or weight of the battery collection bin. The battery collection system can also determine a quantity of fire suppressant to dispense based on at least one of the fill level, volume, or weight of the battery collection bin and / or the quantity, volume, or weight of the objects deposited therein. In response, the battery collection system can dispense the determined quantity of fire suppressant from a fire suppressant cartridge or internal container in the battery collection bin and provide an indication of the number of objects deposited into the battery collection bin and / or its fill level, volume, or weight for display on a client device associated with the battery collection bin.

[0015] Additionally, in some embodiments, the battery collection system, in response to receiving a signal indicating the fill level, volume, or weight of the battery collection bin, further determines that the fill level, volume, or weight has reached a threshold fill level, volume, or weight, and then provides an indication of the threshold fill level, volume, or weight for display on a client device associated with the battery collection bin and locks one or more access doors to restrict access to the battery collection bin. Also, in one or more embodiments, the battery collection system, in response to receiving a signal indicating the volume, weight, or fill level of fire suppressant available for dispersal, determines that the amount of fire suppressant available is below a threshold, and then provides an indication of insufficient fire suppressant available for display on a client device associated with the battery collection bin and / or locks one or more access doors to restrict access to the battery collection bin.

[0016] Furthermore, one or more embodiments of the apparatus for retrieving batteries include a battery retrieval bin with an enclosure configured to receive and secure a transport drum for storing and transporting the deposited batteries and devices. The apparatus also includes a chute operable to direct the deposited batteries or devices into the transport drum when positioned within the enclosure or bin. Furthermore, in some embodiments, a removable fire suppressant cartridge or internal fire suppressant container is disposed above the transport drum and associated with a fire suppressant dispensing mechanism configured to selectively dispense fire suppressant from the fire suppressant cartridge or internal fire suppressant container into the transport drum when a battery is deposited therein via the chute. Additionally, in some embodiments, the apparatus further includes one or more sensors configured to determine one or more of: a fill level, volume, or weight of the transport drum within the enclosure; a thermal characteristic within the enclosure; a carbon dioxide level within the enclosure; a number of batteries or devices deposited in the transport drum within the enclosure; and / or a volume, weight, or fill level of undistributed fire suppressant in the fire suppressant cartridge or internal fire suppressant container.

[0017] Additionally, one or more embodiments of the battery collection bin may include one or more mechanisms for ensuring that fire suppressant does not spill when filling the internal fire suppressant container. For example, one or more embodiments of the battery collection bin may include a jug mounting bracket to help ensure that the jug does not fall during filling. Additionally, one or more embodiments of the battery collection bin may include an entrance cover to prevent dust or fire suppressant particles from escaping the battery collection bin.

[0018] Thus, the disclosed embodiments provide convenient and safe deposit of batteries and devices without the assistance of trained personnel. Indeed, the disclosed system can accurately and efficiently detect the deposit of individual batteries or devices and determine the amount of fire suppressant needed to prevent a thermal event. By intelligently dispensing fire suppressant in response to each deposited battery, the disclosed system can accept and safely handle virtually anything an unsupervised consumer might deposit, including damaged lithium-ion batteries or devices and other types of potentially dangerous batteries. For example, by dispensing fire suppressant in response to each deposit, the disclosed system can proactively prevent a thermal event. Furthermore, if a thermal event does occur, the disclosed system can prevent its spread to other batteries and / or devices stored in the battery collection bin (e.g., by dispensing fire suppressant to deprive the event of oxygen).

[0019] Thus, the disclosed battery collection system offers many advantages and benefits over conventional systems and methods. For example, by utilizing a secure, enclosed environment in which batteries and devices can be deposited, the disclosed embodiments enable consumers to safely deposit batteries and devices with minimal effort and without assistance from trained personnel. Indeed, a consumer can safely deposit one or more batteries or devices by simply inserting each battery through a chute in a battery collection bin located, for example, near the front of a convenience store or grocery store. Additionally, battery collection bins according to one or more embodiments may be provided both indoors (e.g., inside a convenience store or supermarket) and outdoors (e.g., in front of a gas station or other storefront). Indeed, in some embodiments, tamper-resistant, secure battery collection bins may be provided in locations that offer consumers 24-hour access.

[0020] Furthermore, by utilizing an automated process for determining the amount of fire suppressant to be dispensed in response to individual battery inputs, the disclosed system improves efficiency and safety compared to conventional systems. Specifically, the disclosed embodiments intelligently analyze signals from one or more sensors to determine the amount of fire suppressant to be dispensed to effectively prevent a thermal event. The disclosed embodiments can also further prevent incidents by monitoring and reacting to battery collection bins and the fill level of fire suppressant available therein to prevent enclosure overfill and / or fire suppressant unavailability.

[0021] As indicated by the foregoing description, the present disclosure utilizes various terms to describe the features and advantages of the disclosed system. Further details regarding the meaning of such terms will now be provided. For example, as used herein, the term "fire suppressant" refers to a material utilized to prevent fires associated with metals, flammable liquids, or volatile materials, such as lithium-ion batteries. For example, in some embodiments, the fire suppressant may include mineral-based fire extinguishing agents such as vermiculite, perlite, expanded clay, expanded polystyrene (EPS), foam glass, fire-resistant or insulating fibers and papers, and other fire, heat, and / or smoke suppressant compounds.

[0022] Further details will now be provided in connection with exemplary figures depicting example embodiments and implementations of the disclosed methods, apparatuses, and systems. For example, Figure 1 shows a battery recovery system 100 according to one or more embodiments. Specifically, Figure 1 shows a see-through side view of the battery recovery system 100 so that various components of the battery recovery system 100 are visible for illustrative purposes.

[0023] As shown in FIG. 1 , the battery collection system 100 includes a battery collection bin 102 having an enclosure sized and configured to receive a transport drum 104 for storing and transporting input batteries and / or devices. In some embodiments, the battery collection bin 102 is configured to receive a variety of drums or similar containers, ranging from 16 gallons to 55 gallons or larger. As shown, the transport drum 104 is movable via a set of casters 106 disposed on a bottom surface of the transport drum 104. In alternative embodiments, the transport drum 104 does not include casters 106. In such embodiments, a barrel dolly is provided for repositioning the transport drum 104, such as, but not limited to, various examples described below in connection with FIGS. 2A-2B, 3A-3B, 7A-7D, 8, 10B, 11A-11B, and 20A-20B.

[0024] In some embodiments, the transport drum 104 comprises steel or other durable material of similar durability for safe and secure storage and / or transportation of the deposited batteries and other devices. In one or more embodiments, the transport drum 104 is pre-loaded with an initial amount of fire suppressant 108 to ensure that the first battery deposited encounters a buffer of fire suppressant material before the battery recovery system 100 distributes any additional amounts of fire suppressant in response to the initial deposition. Alternatively, in some embodiments, the battery recovery bin 102 is configured to deposit the initial amount of fire suppressant 108 upon installation of the transport drum 104.

[0025] In one or more embodiments, the battery collection system 100 also includes a removable cartridge 110 containing a fire suppressant. As shown in FIG. 1 , for example, the battery collection bin 102 is configured to receive and secure the removable cartridge 110. With the removable cartridge 110 loaded into the battery collection bin 102, the battery collection system 100 can dispense the fire suppressant into the transport drum 104 using a dispensing mechanism 112. In an alternative implementation, the battery collection bin includes a fillable internal fire suppressant container rather than the battery collection bin 102 for storing the removable cartridge 110, as described in more detail below. In either case, when a battery is inserted through a feed chute 114 of the battery collection bin 102, the battery collection system 100 dispenses a quantity of fire suppressant from the cartridge 110 via the dispensing mechanism 112.

[0026] Additionally, in some embodiments, the battery collection system 100 actively monitors conditions within the battery collection bin 102, detecting and recording conditions such as the fill level, volume, or weight of the transport drum 104 (or its contents), or detecting the quantity, size, and / or weight of objects as they are deposited into the battery collection bin 102. For example, the battery collection bin 102 includes a sensor array 116 for detecting the deposit of batteries and determining the fill level, volume, or weight of the transport drum 104. Thus, in one or more embodiments, the battery collection system 100 receives signals from the sensor array 116 to determine the number of batteries and / or devices deposited into the battery collection bin 102 and / or the current fill level, volume, or weight of the transport drum 104. In response, the battery collection system can determine the amount of fire suppressant to spray on the deposited batteries to prevent a thermal event and ensure safe storage and transport of the batteries and devices in the transport drum 104.

[0027] In some embodiments, the battery recovery system 100 includes additional sensors and / or devices for monitoring the contents of the transport drum 104. As shown, the battery collection bin 102 includes a sensor 118 for detecting smoke, detecting temperature, and / or identifying CO levels within the battery collection bin 102 enclosure and / or the transport drum 104. In some embodiments, for example, when the battery recovery system 100 detects smoke, high temperature, and / or elevated CO levels via the sensor 118, the battery recovery system 100 dispenses the remainder of the fire suppressant in the cartridge 110 (or in the battery collection bin's internal container) into the transport drum 104 to prevent or stop a fire or other thermal / chemical event. Alternatively or additionally, in some embodiments, the battery recovery system 100 includes additional fire suppression means for responding to a thermal event, such as, but not limited to, a dry chemical extinguisher, commercial kitchen, or CO suppression system. Additionally, in some embodiments, the battery collection bin 102 includes a ventilation system to relieve pressure within its enclosure, as well as a warning system or alarm to notify nearby personnel and local or remote operators and / or emergency personnel of a thermal event or emergency.

[0028] 1 , in some embodiments, the battery collection bin 102 includes a display screen 120 (e.g., an integrated LCD screen). For example, the battery collection system 100 can provide various notifications via the display screen 120, including, but not limited to, general system status (e.g., open, closed, inoperative), the current fill level, volume, or weight of the transport drum 104, an indication of the remaining fire suppression agent in the cartridge 110, the number, volume, and / or weight of currently loaded batteries and / or devices, the current temperature, the current CO2 level, etc. Additionally, in some embodiments, the display (e.g., the display screen 120) can be used for marketing, advertising, and / or presenting statistics related to battery collection and the battery collection network.

[0029] Alternatively or additionally, the battery recovery system 100 may provide such notifications via an alternative client device associated with the battery recovery system, such as, but not limited to, a tablet, computer, or mobile device, for remote or local monitoring of the battery recovery system 100. Relatedly, the battery recovery system 100 may include connectivity via Wi-Fi, Bluetooth, the Internet, a cellular modem, or the like, to enable remote monitoring of bin status, such as fill level, volume, or weight. Remote monitoring, in some implementations, allows for additional shipping drums and inhibitor cartridges or refill jugs to be sent when the battery recovery bin 102 reaches a near-full fill level, volume, or weight.

[0030] Additionally, in one or more embodiments, the battery collection bin 102 also includes a supply chute lock 122 operable to secure the supply chute 114 in a locked position to prevent the introduction of additional batteries or devices. For example, in some implementations, the battery collection system 100 can determine that the fill level, volume, or weight of the transport drum 104 has reached a threshold level (e.g., 90 percent full) and, in response, can cause the supply chute lock 122 to prevent the door of the supply chute 114 from opening. Also, in some implementations, if power to the battery collection bin 102 is lost, the supply chute lock 122 can automatically engage to restrict access or introduction during which the system is unable to dispense fire suppression agent.

[0031] As previously mentioned, the disclosed embodiments may include arrangements that operate in conjunction with a barrel dolly specifically configured to transport and / or position a transport drum within a battery collection bin. For example, FIGS. 2A-2B illustrate an embodiment of a battery collection system 200, according to one or more embodiments, having many similar or identical components to the battery collection system 100 of FIG. 1 , but with a configuration that allows a transport drum 204 to be positioned within the battery collection bin 202 of the battery collection system 200 via a barrel dolly 206. As shown, the barrel dolly 206 includes a lifting mechanism 209, similar to a pallet jack, for transporting and positioning the transport drum 204 within the enclosure of the battery collection bin 202. As shown, the barrel dolly 206 fits within the battery collection bin 202 to secure its storage. In an alternative embodiment, a barrel dolly may be utilized to position the transport drum within the battery collection bin and then removed, leaving the transport drum inside.

[0032] As shown, the battery collection bin 202 includes a removable cartridge 210 of fire suppressant, a dispensing mechanism 212 for selectively dispensing the fire suppressant from the removable cartridge 210 into the transport drum 204, and a hopper 213 for directing the fire suppressant into the dispensing mechanism 212. As mentioned above, in some embodiments, the battery collection bin 202 can include an internal container in place of the removable cartridge 210, which is fillable to provide the fire suppressant for dispensing via the dispensing mechanism 212 (e.g., as described below in connection with Figures 9A-10B and 13A-13C).

[0033] As also shown, the battery collection bin 202 includes a feed chute 214 having a bin funnel for directing the deposited batteries or devices into the transport drum 204. In one or more implementations, the bin funnel mitigates thermal runaway events caused by impacts by directing the deposited objects into the transport drum 204 at a relatively slow velocity. Also, in some embodiments, the bin funnel of the feed chute 214 is monitored by a clog sensor (e.g., an ultrasonic sensor) that performs object counting and triggers an alert for immediate maintenance if an object blocks the bin funnel. Also, in one or more embodiments, the feed chute 214 includes a non-conductive material to prevent shorting of the deposited batteries or devices passing through the feed chute 214.

[0034] 1, the battery collection bin 202 includes a supply chute door 215 that provides access to the supply chute 214, which can be locked automatically or manually when the transport drum 204 reaches a threshold fill level, volume, or weight. Furthermore, in some embodiments, the supply chute door 215 is configured to restrict access to the interior of the battery collection bin. In some embodiments, for example, the supply chute door 215 includes a tray on which batteries can be placed, which blocks access to the interior of the battery collection bin 202 when the supply chute door 215 is in the open position, such that inserted batteries placed in the tray will fall into the transport drum 204 when the supply chute door 215 is subsequently closed.

[0035] Further, in some embodiments, the supply chute door 215 is sized and configured to accept batteries and devices of a predetermined size and / or shape. Indeed, embodiments may include supply chute doors of various sizes, shapes, and designs to accommodate particular use cases. For example, the expected size and shape of batteries and devices may vary between a battery collection bin located at a hardware store, which may expect to receive a variety of power tool batteries, and a battery collection bin located at a sporting goods store, which may expect to receive the relatively large, elongated batteries typically used in e-bikes. Furthermore, some embodiments include supply chute doors and / or trays sized and configured to prevent the deposition of undesirable objects, such as car batteries or similar volatile objects, into the battery collection bin.

[0036] As shown, the battery collection bin 202 also includes a display screen 220 for displaying notifications to a user of the battery collection system 200. As similarly mentioned with respect to the battery collection system 100 of FIG. 1 above, the battery collection system 200 may provide, via the display screen 220, indications regarding the current fill level, volume, or weight of the transport drum 204 and / or the removable cartridge 210 of the internal fire suppressant container, as well as notifications regarding the CO2 and / or heat levels within the battery collection bin 202.

[0037] As mentioned above, the disclosed embodiments may include various systems, devices, and methods for transporting and / or positioning a transport drum within a battery collection bin. For example, FIGS. 3A-3B show a transport drum 304 being loaded into a battery collection bin 302 of a battery collection system 300 according to one or more embodiments. For example, FIG. 3A shows a slide loading mechanism 306a configured to be slidably secured to one or more sides of the transport drum 304. With the slide loading mechanism 306a secured to the transport drum 304, an operator (i.e., a user) can push the transport drum 304 into the battery collection bin 302 by sliding the bracket of the slide loading mechanism 306a that holds the transport drum 304 along the rails of the slide loading mechanism 306a. As an alternative to or in addition to the slide loading mechanism 306a, the battery collection system 300 may include a series of drum rollers 306b, as shown in FIG. 3B. As shown, the drum rollers 306b are configured to allow an operator to slide the transport drum 304 into the interior of the battery collection bin 302. As shown, in some implementations, the slide loading mechanism 306a and / or the drum rollers 306b are operable to slide the transport drum 304 directly onto the pallet without having to lift the transport drum 304.

[0038] In some embodiments, the battery collection bin comprises an upper surface that discourages or prohibits the placement of objects (e.g., clutter, trash, or unused batteries) at the top of the bin, such as an angled or curved surface that slopes down toward the ground. As shown in Figures 3A-3B, for example, the battery collection bin 302 comprises a sloped surface when the cartridge door 303 is closed and / or the battery collection bin 302 is otherwise secured.

[0039] 4A-4C illustrate another battery recovery system 400 according to one or more embodiments. As shown, the battery recovery system 400 includes a battery recovery bin 402 configured to accommodate two removable cartridges 410 containing fire suppressant. Indeed, embodiments may include removable cartridges of fire suppressant of various shapes and sizes. Also, as described above, embodiments may include a fire suppressant container configured to load fire suppressant into the battery recovery bin's internal container via one or more ports.

[0040] 4A , the cartridge door 403 is opened to remove and / or install the removable cartridge 410 within the battery collection bin 402. The bin access door 405 is also shown in an open position to remove and / or install the transport drum 404 within the battery collection bin 402.

[0041] 4B shows the cartridge door 403 and bin access door 405 in a closed position, thereby preparing the battery collection bin to accept batteries and devices through the supply chute door 415. In some implementations, the cartridge door 403 and bin access door 405 are secured (locked) to prevent access or tampering by the consumer. In some embodiments, the bin access door 405 includes a storage space for placing a shipping drum lid. Once the battery collection bin 402 is ready to receive batteries and devices from the consumer, the display screen 420 can indicate to the consumer that the battery collection bin 402 is operational and, in some implementations, can include a prompt with instructions for the consumer to follow.

[0042] 4C illustrates a transport system 430 for shipping transport drums 404 and cartridges 410, according to one or more embodiments. As shown, a pallet 432 is provided with two transport drums 404 and two cartridges 410 for use with the battery collection bin 402 of FIGS. 4A-4B.

[0043] As previously mentioned, disclosed embodiments may include a removable cartridge containing a fire suppressant and a corresponding dispensing mechanism for dispensing the fire suppressant in response to individual battery inputs. For example, Figures 5A-5B show a fire suppressant dispensing system 500 including a removable cartridge 510 containing a fire suppressant 508 and a dispensing mechanism 512, according to one or more embodiments.

[0044] As shown in FIG. 5A , the outlet 507 of a removable cartridge 510 of fire suppressant 508 interfaces with the inlet of a fire suppressant hopper 513. As shown in FIG. 5B , with the outlet 507 of the removable cartridge 510 inserted and secured in the hopper 513, the fire suppressant 508 fills the hopper 513, which directs the fire suppressant 508 toward a dispensing mechanism 512 for selective dispensing of the fire suppressant 508 into corresponding transport drums within a battery recovery bin. In some embodiments, the dispensing mechanism 512 is operated by a low-voltage motor (e.g., a 12-volt DC stepper motor) configured to selectively dispense metered amounts of the fire suppressant 508. In some embodiments, each removable cartridge 510 is vacuum-sealed to the inlet of the hopper 513 to ensure retention of the fire suppressant 508 within a confined environment.

[0045] Additionally, in one or more embodiments, the fire suppressant dispensing system 500 includes a dispensing mechanism 512 that includes an auger fed by a hopper 513. In some embodiments, for example, the dispensing mechanism 512 includes a sliding compartment operable by a motor to open and release the fire suppressant 508 over a determined number of seconds to dispense a specific amount of the fire suppressant 508 into a transport drum positioned below the dispensing mechanism 512. In other embodiments, the fire suppressant dispensing system includes an interval system in which, at multiple predetermined thresholds based on the total volume of the corresponding transport drum, a nozzle pierces the cover of a single cartridge in a series of cartridges to release the fire suppressant into the transport drum.

[0046] In one or more embodiments, the fire suppressant dispensing system 500 enables the dispensing and even distribution of fire suppressant into transport drums within the battery collection bin among collected batteries and devices without user intervention. In some implementations, after objects are deposited into the bin, the fire suppressant dispensing system 500 dispenses a controlled amount of fire suppressant into the transport drum based on a threshold derived from the volume, weight, or quantity of the sensed objects. Also, in some implementations, if the bin collection system's sensors identify a temperature spike or detect smoke, the fire suppressant dispensing system 500 completely transfers the fire suppressant 508 from the removable cartridge 510 into the corresponding drum.

[0047] 6A-6C illustrate various views of removable cartridges 610 for providing fire suppressant to a battery recovery system, according to one or more embodiments. As shown, each removable cartridge 610 includes multiple handles 611 for ease of handling. Each removable cartridge 610 also includes an outlet 607 configured to interface with a corresponding fire suppressant distribution system of the battery recovery bin, as described above in connection with FIGS. 5A-5B. Cartridges such as removable cartridge 610 can be manufactured by a variety of procedures, including, but not limited to, 3D printing, blow molding, and the like.

[0048] In one or more embodiments, the battery collection system includes a fire suppressant cartridge that is sealed to keep the fire suppressant dust-free and prevent tampering or other inadvertent destruction of the fire suppressant during transport or storage. In some embodiments, the fire suppressant cartridge is refillable so that a donor or operator can fill the cartridge from a larger supply, whether the cartridge is a removable cartridge configured to be positioned within a battery collection bin (e.g., as shown in FIGS. 6A-6C) or a cartridge / jug configured to be transferred into the internal container of a battery collection bin (e.g., as shown in FIGS. 9A-10B and 13A-13C).

[0049] As previously mentioned, the disclosed embodiments may include various systems, apparatus, and methods for positioning transport drums configured to store input batteries and other devices. For example, Figures 7A-7D illustrate a method for positioning a transport drum 704 on a pallet 732 utilizing a barrel dolly 706, according to one or more embodiments.

[0050] As shown in Figure 7A, the transport drum 704 is loaded onto a barrel dolly 706 and lifted above a pallet 732 using a jack handle 709 of the barrel dolly 706. Next, as shown in Figure 7B, the barrel dolly 706 is pushed into a position below the pallet 732 so that the transport drum 704 is in a position above the pallet 732. As shown in Figure 7C, the transport drum 704 is lowered onto the pallet 732 using the jack handle 709 of the barrel dolly 706. Finally, the operation is completed by pulling the barrel dolly 706 away from the pallet 732, as shown in Figure 7D.

[0051] 8 illustrates another exemplary embodiment of a battery recovery system 800. As shown, the battery recovery system 800 may include various embodiments of a battery recovery bin 802, a fire suppressant cartridge or container 810, a transport drum 804, and / or a loading mechanism 806 for the transport drum 804. For example, the battery recovery system of FIG. 8 includes an alternative design of a transport dolly configured to securely lift and transport the transport drum to and from the battery recovery bin.

[0052] Additionally, Figure 8 illustrates an alternative design for a fire suppressant cartridge. As shown, a fire suppressant container 810 is configured to carry a predetermined amount of fire suppressant for filling an internal container of a battery collection bin 802. As shown in Figures 9A-10B, for example, the fire suppressant container 810 is configured to interface with a port in the battery collection bin to fill the internal container within the battery collection bin with fire suppressant, rather than inserting and securing a cartridge within the battery collection bin (i.e., as shown in Figures 2A, 4A, and 5A-5B).

[0053] As described above, some embodiments of the battery collection system include a container within the battery collection bin that is loadable (i.e., fillable) with fire suppressant for selective dispersal onto batteries and / or devices deposited within the battery collection bin. For example, FIGS. 9A-9B illustrate one embodiment of a battery collection system 900 having a battery collection bin 902 with an interior container 904 configured to receive, store, and direct fire suppressant for dispersal onto deposited objects. In particular, FIGS. 9A-9B illustrate the interior container 904 of the battery collection bin 902 being filled with fire suppressant from a fire suppressant container 810 (e.g., as shown in FIG. 8) through one of multiple entrances 906 above the interior container 904.

[0054] 10A-10B illustrate an additional embodiment of a battery collection system 1000 being filled with fire suppressant from a fire suppressant container 810 (e.g., as shown in FIG. 8). In particular, FIGS. 10A-10B illustrate a see-through view of a battery collection bin 1002 having an inner container 1004 that feeds into a hopper 1006 for selectively dispensing fire suppressant into a transport drum 1008 positioned within the battery collection bin 1002. As also shown in FIG. 10B, in some embodiments, the battery collection bin 1002 may include a panel 1010 configured to pivot open to provide access to a fill hole 1012 above the inner container 1004 of the battery collection bin 1002 and to direct any leaking fire suppressant into the transport drum 1008 below.

[0055] As previously discussed, embodiments of the battery recovery system may include various tools or devices for lifting and transporting transport drums or similar containers. For example, FIGS. 11A-11B illustrate yet another embodiment of a transport drum lifting mechanism or barrel dolly 1102. As shown, the barrel dolly 1102 includes a lifting mechanism operable by an elongated handle 1104. Thus, the barrel dolly 1102 may be configured to lift the transport barrel 1106, whether empty, partially filled, or fully loaded, without the need for additional tools or machinery. As also shown in FIGS. 11A-11B, in some embodiments, the barrel dolly 1102 is configured with a barrel strap 1108 that can be secured to an outer surface around the circumference of the transport barrel 1106. As shown, the barrel strap 1108 may provide additional support to the transport barrel 1106 during the lifting and transport operation.

[0056] As mentioned above, one or more embodiments of the battery recovery system include a display of information and / or notifications regarding the status of one or more battery collection bins. Such a display or user interface may be depicted via a display screen on the battery collection bin itself or via a client device, such as, but not limited to, a personal computer, tablet, or mobile phone. For example, FIG. 12 shows an exemplary user interface 1200 for providing controls and notifications to an operator. For example, the user interface 1200 may include controls 1202 for locking one or more doors or access points of the battery collection bin (e.g., the selectable option labeled "Lock Bin" in FIG. 12) to restrict access thereto. Furthermore, in some embodiments, the user interface includes controls 1202 for activating / deactivating various features of the battery recovery system, such as an auger motor for dispensing fire suppressant (e.g., the selectable option labeled "Motor On" in FIG. 12) or any of the various sensors described herein.

[0057] As further shown in FIG. 12 , the display or user interface 1200 may include various notification or status indicators 1204 for the battery recovery system. For example, a level indicator may be provided that graphically illustrates the percent fill level or volume of the battery recovery bin. Also included is a light indicator that can indicate to an operator whether the chute door is currently open or partially open due to a jam or other issue. Additionally, numerical indications may be included, such as the “Motor Running” and “Door Locked” indications shown in FIG. 12 . Thus, in some embodiments, the battery recovery system may be monitored and / or controlled remotely or locally via a user interface, such as, but not limited to, the exemplary interface provided in FIG. 12 . Furthermore, in one or more embodiments, network connectivity is not required for the safe and efficient operation of the battery recovery system, as the system can operate without human interaction.

[0058] As mentioned above, one or more embodiments of the battery recovery system include an internal container and / or hopper for safely storing fire suppressant that can be filled via a fire suppressant container. For example, FIGS. 13A-13C show a battery recovery system 1300 that includes a battery recovery bin 1302 that is being filled with fire suppressant from a fire suppressant container or jug ​​1304. In some implementations, for example, the fire suppressant is provided via one or more fire suppressant containers (such as fire suppressant jugs 1304) to allow an operator to fill the internal container of the battery recovery bin 1302 with the fire suppressant.

[0059] 13A and 13B , for example, a battery collection bin 1302 includes multiple entrances 1306 accessible via hinged access panels 1308 positioned above a supply chute door 1310, whereby the hinged access panels 1308 can be locked to prevent tampering by customers when the battery collection bin 1302 is in operation. Additionally, the hinged access panels 1308 are positioned and configured to open below the entrances 1306, ensuring visibility by operators while the battery collection bin 1302 is being filled with fire suppression agent. Also as shown, each of the entrances 1306 is further covered by an entrance cover 1312 (e.g., a hinged dust flap) when not in use to prevent fire suppression agent (or dust particles thereof) from leaking through the entrances 1306 when the battery collection bin 1302 is in operation. In some embodiments, the entrance cover 1312 is positioned so that closing the hinged access panel 1308 also closes the entrance cover 1312, thus preventing an operator from inadvertently leaving the entrance cover 1312 in an open position.

[0060] To load fire suppressant into the internal container of the battery collection bin 1302, an operator can associate the cap 1318 of the fire suppressant container 1304 with one of the entrances 1306 and open the fire suppressant container 1304 via a sliding gate 1314 integrated with the cap 1318. The battery collection bin 1302 also includes a retaining bracket 1316 associated with each entrance 1306 for holding the fire suppressant container 1304 in place while filling the internal container of the battery collection bin 1302. In some implementations, for example, an operator can secure the fire suppressant container 1304 to the retaining bracket 1316 and then actuate (open) the sliding gate 1314 to dispense the fire suppressant into the internal container of the battery collection bin 1302. Thus, an operator can secure the fire suppressant container 1304 to one of the entrances 1306 without additional tools or components to prevent spillage while filling the battery collection bin 1302 with fire suppressant. In the illustrated implementation, the battery collection bin 1302 includes two entrances 1306 and associated retaining brackets 1316, allowing for the simultaneous dispensing of two fire suppressant cartridges. In some embodiments, additional entrances (or a single entrance) may be provided.

[0061] As particularly shown in FIG. 13C , the fire suppressant container 1304 may comprise a jug sized and configured to be conveniently and safely handled by an operator to fill the battery collection bin 1302 with fire suppressant as needed. The fire suppressant container 1304 may include, for example, a locking cap 1318 having a sliding gate 1314 that may be selectively opened during operation and locked during storage or transport without the use of tools. Additionally, the fire suppressant container 1304 includes a handle 1320 for ease of transportation. In various embodiments, the fire suppressant container 1304 is sized to be easily carried by an operator. In one or more embodiments, for example, the fire suppressant container 1304 weighs approximately 10 pounds or less when fully loaded with fire suppressant.

[0062] Additionally, in one or more embodiments, the battery collection system includes additional safety features, such as components to prevent customer exposure to fire suppression agent, temperature rise due to overheating of batteries placed in the battery collection bin, and / or impact blast from explosions occurring within the battery collection bin. For example, Figures 14A-14B illustrate various spill prevention features of a battery collection bin 1302 configured to prevent fire suppression agent from spilling while the battery collection bin 1302 is being filled (e.g., as described above in connection with Figures 13A-13C).

[0063] 14A-14B , for example, the battery collection bin 1302 includes an interior overflow channel 1328 positioned between the retaining bracket 1316 and the interior of the supply chute door 1310. Additionally, the battery collection bin 1302 includes an overflow ramp configured to direct any fire suppressant spilled during filling into the interior overflow channel 1328. As shown, the overflow ramp is positioned at a downward angle from the retaining bracket 1316 and includes a pair of angled rails 1330 positioned to further direct the fire suppressant toward the interior overflow channel 1328. Thus, if fire suppressant is inadvertently spilled (e.g., near the retaining bracket 1316) during filling, the spilled fire suppressant is directed by the overflow ramp and angled rails 1330 into the interior overflow channel 1328 and toward the interior of the supply chute door 1310 (shown as transparent in FIGS. 14A-14B ), thereby entering the enclosure 1324 of the battery collection bin 1302. Alternatively, in some embodiments, spilled fire suppressant may be directed into the internal container 1322 of the battery collection bin 1302 for later dispensing (e.g., when an object is deposited) via the fire suppressant dispenser 1323. Thus, when the access panel 1308, supply chute door 1310, and enclosure access door 1326 of the battery collection bin 1302 are secured, consumers and operators of the battery collection bin 1302 are not exposed to fire suppressant that may inadvertently be spilled near the entrance 1306 during filling of the internal container 1322.

[0064] Furthermore, in some embodiments, the battery collection system includes additional features to ensure the effective and safe deposit of batteries and other objects within the battery collection bin. For example, FIG. 15A illustrates the supply chute door 1310 of the battery collection bin 1302 in an open position, and FIG. 15B illustrates various features associated with the supply chute door 1310. For example, as particularly shown in FIG. 15B , the supply chute door 1310, when in the closed position, has a relatively steep interior angle (e.g., approximately 35 degrees below horizontal) to ensure that objects slide freely down the supply chute when deposited. Also, in one or more embodiments, the supply chute door 1310 is sized and positioned to allow the deposit of common consumer batteries and electronic devices (e.g., laptop computer, power tool batteries, etc.) therein while preventing the insertion of undesirable batteries and objects (e.g., automobile batteries and other lead-acid batteries). 15B, the battery collection bin 1302 includes an obstruction sensor 1334 configured to detect an obstruction in the passage between the supply chute door 1310 and the enclosure of the battery collection bin 1302. In some embodiments, for example, the battery collection system 1300 can restrict consumer access to the battery collection bin 1302 until the obstruction detected by the obstruction sensor 1334 is removed.

[0065] In some embodiments, the supply chute door 1310 is locked or otherwise secured to prevent the supply chute door 1310 from suddenly opening in the event of a fire or explosion in the battery collection bin 1302. As shown in FIG. 15B , for example, the supply chute door 1310 includes a finger sensor 1332 (e.g., beneath its handle) configured to detect user interaction therewith in order to unlock or otherwise activate the supply chute door 1310 for the insertion of objects therein. In one or more embodiments, the finger sensor 1332 comprises a low-voltage light sensor configured to detect interaction with a user's finger on or within the handle of the supply chute door 1310. In some implementations, for example, the finger sensor 1332 comprises a light sensor beam that intersects between a light emitter and a light receiver on opposing insides of the handle, such that user interaction with the handle breaks the light sensor beam and triggers the finger sensor 1332, unlocking the supply chute door 1310. Alternatively, in some embodiments, the battery collection bin 1302 may include an activation switch near the supply chute door 1310 that, when activated by a user, temporarily unlocks or otherwise activates the supply chute door 1310. Also, in one or more embodiments, the supply chute door 1310 is counterweighted, spring loaded, or otherwise prevented from remaining in an open position.

[0066] 15B , the battery collection bin 1302 includes a dust curtain 1336 to prevent fire suppressant and other particulates from escaping from the interior of the battery collection bin. In some embodiments, for example, the dust curtain 1336 includes a specific weight of non-flammable silicone that allows lightweight objects to fall into the drum while preventing particulates from leaving the enclosure. Furthermore, in some embodiments, the dust curtain 1336 is sized and positioned to limit the line of sight into the enclosure when the supply chute door 1310 is opened. Also, in some embodiments, a portion of the supply chute door 1310 further prevents line of sight and physical access to the interior of the battery collection bin 1302, as well as protecting the user in the event of an explosion or excessive heat from within the battery collection bin 1302.

[0067] Additionally, in one or more embodiments, the battery collection bin may include additional safety features configured to redirect explosive or thermal forces generated within its enclosure away from the consumer. For example, FIGS. 16A-16B show an impact blast plate 1338 on the back of the battery collection bin 1302, which is configured to open in response to an impact within the battery collection bin 1302 (e.g., due to a battery exploding therein). Also, in some embodiments, the impact blast plate 1338 is sized and configured to remain flush with the back of the battery collection bin 1302 during normal operation, preventing tampering and / or access to the interior of the battery collection bin 1302.

[0068] As mentioned above, in some embodiments, the battery collection bin includes one or more sensors for detecting the level of fire suppression agent available for dispersal onto deposited objects. For example, FIG. 17 shows a battery collection bin 1302 having a lower fill sensor 1340a and an upper fill sensor 1340b positioned within its internal container 1322. In the illustrated embodiment, for example, the internal container 1322 comprises a hopper sized and configured to hold at least the amount of fire suppression agent needed to fill a shipping drum (e.g., a 55-gallon drum). In some embodiments, the internal container 1322 is sized and configured to hold more fire suppression agent than needed to fill the shipping drum (e.g., for future use, if needed), such as, but not limited to, an additional 25 percent of the amount needed to fill the shipping drum.

[0069] 17 , lower fill sensor 1340a is positioned within inner container 1322 at a lower level relative to fire suppressant dispenser 1323 and is configured to detect when inner container 1322 is empty or otherwise below a lower threshold amount of fire suppressant. Similarly, upper fill sensor 1340b is positioned within inner container 1322 at a higher level relative to fire suppressant dispenser 1323 and is configured to detect when inner container 1322 is filled with an upper threshold amount of fire suppressant. In some embodiments, for example, lower and upper fill sensors 1340a-b comprise light emitters and light receivers positioned on opposing interior walls of inner container 1322, such that light emitted by each emitter is detected by each respective receiver when there is no fire suppressant therebetween. Thus, battery recovery system 1300 can detect and notify an operator (e.g., via a user interface or other indicator) when inner container 1322 is filling with fire suppressant or when filling has stopped. Alternatively, in one or more embodiments, a different type of sensor is utilized to detect the level of fire suppressant available, such as a sensor to detect the weight of the fire suppressant in the inner container 1322.

[0070] As mentioned above, in one or more embodiments, the battery collection bin utilizes a fire suppression dispenser mechanism to dispense fire suppressant onto deposited objects. For example, FIGS. 18A-18B show a fire suppressant dispenser 1323 within the battery collection bin 1302. As shown, the fire suppressant dispenser 1323 is positioned at the lower end of the hopper of the inner container 1322 and comprises a sliding gate 1343 coupled to a linear motor 1342 configured to open and close the sliding gate 1343 to dispense fire suppressant from the inner container 1322 into the enclosure below. In some embodiments, the linear motor 1342 comprises a gear-reduced, high-torque, low-speed motor configured to permit and restrict the flow of fire suppressant without stalling. Additionally, in one or more embodiments, the sliding gate 1343 is monitored by forward and rearward limit switches to detect blockages and, in some cases, restrict user access to the battery collection bin 1302 until the detected blockage is cleared. Additionally, in some embodiments, the battery collection bin 1302 includes a sliding cover (e.g., a grille) immediately below and / or above the sliding gate 1343 to prevent fingers or other objects from interacting with the sliding gate 1343 during operation.

[0071] Also, as described above, in some embodiments, the inner container of the battery collection bin includes an emergency release hatch configured to release fire suppression agent into the bin enclosure in the event of an explosion or thermal event. For example, FIGS. 19A-19B show an emergency release hatch 1344 positioned at the lower end of the hopper of the inner container 1322 and configured to release remaining fire suppression agent into the enclosure below. As shown, the emergency release hatch 1344 includes a fusible link 1346 configured to break in response to elevated temperatures emanating from the enclosure below, and a spring hinge 1348 configured to open when the fusible link 1346 breaks due to the elevated temperatures. In some embodiments, for example, the fusible link 1346 is configured to melt or otherwise break when it reaches a temperature above 135 degrees Fahrenheit. Thus, if the fusible link 1346 melts or otherwise fails, the spring hinge 1348 forces at least one flap open, thus exposing a hole in the inner vessel 1322 and allowing the fire suppressant therein to migrate to the enclosure below.

[0072] As mentioned above, some embodiments of the battery collection system include a drum trolley for transporting and positioning the battery collection drums within the battery collection bin enclosure. For example, Figures 20A-20D show a drum trolley 2002 loaded with a drum 2004 (e.g., a 55-gallon metal drum). In particular, the drum trolley 2002 holds the drum 2004 and provides assistance to an operator in lifting and moving the drum 2004 for safe transport of full and empty drums between the battery collection bin and a loading dock for transport.

[0073] As shown in FIGS. 20A-20D , the drum 2004 is secured to the drum trolley 2002 using straps 2006 (e.g., quick-release nylon straps) and metal support bands 2010, thus providing horizontal support to prevent the drum 2004 from sliding off the drum trolley 2002 during lifting and transport. Thus, when the drum 2004 is delivered to an operator on a pallet, the tines of the drum trolley 2002 can be wedged under the pallet and the drum 2004 secured by the straps 2006. Also as shown, the drum trolley 2002 includes a lifting arm 2012 for lifting the secured drum 2004 for removal from the ground or pallet. In some embodiments, the lifting arm 2012 is spring-assisted and / or includes a locking mechanism for holding the drum 2004 in a raised position (e.g., as particularly shown in FIG. 20A ). Furthermore, in some embodiments, the drum trolley 2002 includes one or more over-travel protrusions to prevent the drum 2004 from colliding with the drum trolley 2002 in the event of a sudden release of the lifting arm 2012. With the drum 2004 secured to the drum trolley 2002, an operator can move the drum 2004 with assistance from one or more provided handles 2014 and wheels or casters 2008 disposed beneath the drum trolley 2002.

[0074] 1-20D, corresponding text, and examples provide several different methods, systems, devices, and non-transitory computer-readable media of embodiments of a battery recovery system. In addition to the above, one or more embodiments may also be described in terms of a flowchart including acts for achieving a particular result, such as shown in FIG. 21. FIG. 21 may be performed with more or fewer acts. Furthermore, these acts may be performed in a different order. Furthermore, acts described herein may be repeated or performed in parallel with each other or with different instances of the same or similar acts.

[0075] As mentioned above, FIG. 21 illustrates a flowchart of a series of actions 2100 for automating the distribution of fire suppression agent onto batteries or devices deposited in a battery collection bin of a battery collection system, according to one or more embodiments. While FIG. 21 illustrates actions according to one embodiment, alternative embodiments may omit, add, reorder, and / or modify any of the actions shown in FIG. 21. The actions of FIG. 21 may be performed as part of a method. Alternatively, a non-transitory computer-readable medium may contain instructions that, when executed by one or more processors, cause a computing device to perform the actions of FIG. 21. In some embodiments, a system may perform the actions of FIG. 21.

[0076] 21 illustrates an example series of acts 2100 for automating the distribution of fire suppressant onto batteries or devices deposited in a battery collection bin. The series of acts 2100 may include an act 2102 of receiving a signal indicating that an object has been deposited into the battery collection bin. In certain embodiments, act 2102 includes receiving a signal from one or more sensors indicating the object deposited into the battery collection bin and the fill level of the battery collection bin.

[0077] 21 , the series of acts 2100 may include an act 2104 of determining a quantity of fire suppressant to be dispensed. In certain embodiments, act 2104 includes determining the quantity of fire suppressant based at least on the fill level of the battery collection bin. Also, in some embodiments, act 2104 includes determining the quantity of fire suppressant based on the fill level of the battery collection bin and the detected weight of the deposited object. In some embodiments, the battery recovery system utilizes a fire suppressant loading model, such as, but not limited to, a machine learning model or a neural network, to determine the quantity of fire suppressant to be dispensed based on various detected attributes (e.g., quantity, weight, volume, or other classification of the deposited object).

[0083] Embodiments of the present disclosure may include or utilize special-purpose or general-purpose computers including computer hardware such as, for example, one or more processors and system memory, as described in more detail below. Embodiments within the scope of the present disclosure also include physical and other computer-readable media for carrying or storing computer-executable instructions and / or data structures. In particular, one or more of the processes described herein may be embodied in a non-transitory computer-readable medium and implemented at least in part as instructions executable by one or more computing devices (e.g., any of the media content access devices described herein). Generally, a processor (e.g., a microprocessor) receives instructions from a non-transitory computer-readable medium (e.g., memory) and executes those instructions, thereby performing one or more processes, including one or more of the processes described herein.

[0084] Computer-readable media may be any available media that can be accessed by a general-purpose or special-purpose computer system. Computer-readable media that store computer-executable instructions are non-transitory computer-readable storage media (devices). Computer-readable media that carry computer-executable instructions are transmission media. Thus, by way of example, and not limitation, embodiments of the present disclosure may include at least two distinctly different kinds of computer-readable media: non-transitory computer-readable storage media (devices) and transmission media.

[0085] Non-transitory computer-readable storage media (devices) include RAM, ROM, EEPROM, CD-ROM, solid-state drives (“SSD”) (e.g., RAM-based), flash memory, phase-change memory (“PCM”), other types of memory, other optical disk storage, magnetic disk storage, or other magnetic storage devices, or any other medium that can be used to store desired program code means in the form of computer-executable instructions or data structures and that can be accessed by a general-purpose or special-purpose computer.

[0086] A "network" is defined as one or more data links that enable the transport of electronic data between computer systems and / or modules and / or other electronic devices. When information is transferred or provided over a network or another communications connection (either hardwired, wireless, or a combination of hardwired or wireless) to a computer, the computer properly views the connection as a transmission medium. Transmission media may include networks and / or data links that may be used to transport desired program code means in the form of computer-executable instructions or data structures and that may be accessed by a general-purpose or special-purpose computer. Combinations of the above should also be included within the scope of computer-readable media.

[0087] Furthermore, upon reaching various computer system components, program code means in the form of computer-executable instructions or data structures may be automatically transferred from transmission media to non-transitory computer-readable storage media (devices) (or vice versa). For example, computer-executable instructions or data structures received over a network or data link may be buffered in RAM within a network interface module (e.g., a "NIC") and then eventually transferred to computer system RAM and / or less volatile computer storage media (devices) in the computer system. Thus, it should be understood that non-transitory computer-readable storage media (devices) may be included in computer system components that also (or even primarily) utilize transmission media.

[0088] Computer-executable instructions include, for example, instructions and data that, when executed by a processor, cause a general-purpose computer, a special-purpose computer, or a special-purpose processing device to perform a certain function or group of functions. In some embodiments, computer-executable instructions are executed by a general-purpose computer to transform the general-purpose computer into a special-purpose computer that implements elements of the present disclosure. Computer-executable instructions may be, for example, binaries, intermediate format instructions such as assembly language, or even source code. While the present subject matter has been described in language specific to structural features and / or methodological acts, it should be understood that the subject matter defined in the appended claims is not necessarily limited to the described features or acts described above. Rather, the described features and acts are disclosed as example forms of implementing the claims.

[0089] Those skilled in the art will appreciate that the present disclosure may be implemented in networked computing environments having many types of computer system configurations, including personal computers, desktop computers, laptop computers, message processors, handheld devices, multiprocessor systems, microprocessor-based or programmable consumer electronics, network PCs, minicomputers, mainframe computers, cellular phones, PDAs, tablets, pagers, routers, switches, etc. The present disclosure may also be implemented in distributed system environments where tasks are performed by both local and remote computer systems that are linked through a network (either by hardwired data links, wireless data links, or a combination of hardwired and wireless data links). In a distributed system environment, program modules may be located in both local and remote memory storage devices.

[0090] Embodiments of the present disclosure may also be implemented in a cloud computing environment. As used herein, the term "cloud computing" refers to a model for enabling on-demand network access to a shared pool of configurable computing resources. For example, cloud computing may be adopted in the market to provide ubiquitous, convenient, on-demand access to a shared pool of configurable computing resources. The shared pool of configurable computing resources may be rapidly provisioned through virtualization, released with little management effort or service provider interaction, and then scaled accordingly.

[0091] Cloud computing models may consist of various characteristics, such as, for example, on-demand self-service, wide area network access, resource pooling, rapid elasticity, and measured service. Cloud computing models may also expose various service models, such as, for example, Software as a Service ("SaaS"), Platform as a Service ("PaaS"), and Infrastructure as a Service ("IaaS"). Cloud computing models may also be deployed using different deployment models, such as private cloud, community cloud, public cloud, and hybrid cloud. Also, as used herein, the term "cloud computing environment" refers to an environment in which cloud computing is employed.
