Description

Technology Field

[0001] The present invention relates to a battery active disassembly device, and more specifically, to a battery active disassembly device capable of effectively disassembling a used battery while minimizing environmental impact by causing permanent damage to the battery at the necessary time. Background Technology

[0002] Recently, the use of batteries in various industrial devices has been increasing, and accordingly, technical requirements for the disposal or dismantling of used batteries are also rising.

[0003] In particular, for batteries used in remote areas where direct recovery is difficult, since it is challenging to collect and dispose of them directly after use, they need to be designed to self-decompose while minimizing environmental impact.

[0004] In this regard, Japanese Patent Publication No. 2022-545009 discloses a technology for a biodegradable electrochemical device, which describes a battery containing a biodegradable composition that enables a used battery to be biodegraded in an environmentally friendly manner in a natural environment.

[0005] However, batteries containing such biodegradable compositions merely decompose on their own when left in the natural environment for a long period, which means that disposal or decomposition takes a considerable amount of time. Furthermore, there is a limitation in that even more time is required for the final decomposition of the battery, particularly if the penetration of external substances is hindered through the casing material constituting the battery.

[0006] Therefore, even if an eco-friendly battery containing a biodegradable composition is used, actions such as physically inducing the degradation of the battery are required when the use is ultimately completed, and to date, technology to induce such physical degradation of a battery after use has not been developed. Prior art literature

[0007] Japanese Patent Publication No. 2022-545009 The problem to be solved

[0008] Accordingly, the technical problem of the present invention is conceived from this point, and the objective of the present invention is to provide an active battery disassembly device capable of effectively disassembling a used battery in a relatively short time while minimizing environmental impact by causing permanent damage to the battery at the necessary time. means of solving the problem

[0009] A battery active disassembly device according to one embodiment for realizing the above-described objective of the present invention includes a first battery unit, a trigger unit, and a switching element. The first battery unit provides power to a driving element. The trigger unit causes permanent damage to the first battery unit when the use of the first battery unit is completed. The switching element is connected between the first battery unit and the trigger unit and controls the driving of the trigger unit when the use of the first battery unit is completed.

[0010] In one embodiment, the trigger unit is a shape memory alloy, and permanent damage to the first battery unit may be induced as the shape of the trigger unit is restored.

[0011] In one embodiment, depending on the driving control of the switching element, the trigger unit is supplied with power, heated, and its shape can be restored.

[0012] In one embodiment, the trigger unit may have a wire shape.

[0013] In one embodiment, the first battery unit may include a first packaging portion comprising a first internal unit that supplies power to the driving element portion, a first main packaging that covers the first internal unit, and a first extension packaging that protrudes in one direction from the first main packaging.

[0014] In one embodiment, the trigger unit may be driven to break the first extension packaging as it is heated.

[0015] In one embodiment, the first packaging portion may include a wax material.

[0016] In one embodiment, a second battery unit may be further included, connected between the switching element and the trigger unit, to provide a reference voltage for the driving time of the trigger unit.

[0017] In one embodiment, the switching element may cut off power supply to the trigger unit when the voltage of the first battery unit is greater than the voltage of the second battery unit, and allow power from the first battery unit to be supplied to the trigger unit when the voltage of the first battery unit is less than the voltage of the second battery unit.

[0018] In one embodiment, a second battery unit may be further included, connected between the switching element and the trigger unit to provide power for driving the trigger unit.

[0019] In one embodiment, the switching element may cut off power supply to the trigger unit when the voltage of the first battery unit is greater than the voltage of the second battery unit, and allow power from the second battery unit to be supplied to the trigger unit when the voltage of the first battery unit is less than the voltage of the second battery unit.

[0020] In one embodiment, the trigger unit can simultaneously cause permanent damage to the second battery unit when the use of the first battery unit is completed.

[0021] In one embodiment, the trigger unit is extended to wrap around the outside of the first extension packaging of the first battery unit and the second extension packaging of the second battery unit, and can be deformed so as to decrease in length as heated.

[0022] In one embodiment, the trigger unit is positioned between the first extension packaging of the first battery unit and the second extension packaging of the second battery unit and can be deformed to increase in length as it is heated.

[0023] In one embodiment, a sensor unit connected between the switching element and the trigger unit and monitoring an external environment condition may be further included. Effects of the invention

[0024] According to embodiments of the present invention, when the use of the battery ends, artificial permanent damage can be caused to induce rapid and effective decomposition in the natural environment.

[0025] That is, a trigger unit induced to return to its original shape using a shape memory alloy can apply a physical impact to the battery unit, thereby inducing permanent damage to the battery unit and rapidly and effectively inducing self-decomposition.

[0026] In this case, the trigger unit returns to its original shape simply by being heated with power, and the battery unit may be designed to receive physical impact as the trigger unit returns to its original shape. That is, the battery unit includes a wax material and an extension packaging to which the trigger unit is fixed, and the trigger unit can induce permanent damage to the battery unit by breaking the extension packaging through deformation.

[0027] Meanwhile, regarding the power supply for heating the trigger unit, the second battery unit may provide a reference voltage to determine the timing of power supply to the trigger unit, or alternatively, the second battery unit may directly supply power to the trigger unit. Furthermore, since the power supply to the trigger unit is controlled through a switching element, the power supply to the trigger unit can be controlled through a circuit containing a relatively simple switching element.

[0028] In addition, if the surrounding environment is not suitable for heating the trigger unit through the sensor unit, effective heating of the trigger unit can be induced by cutting off the unnecessary power supply. Brief explanation of the drawing

[0034] Hereinafter, preferred embodiments of the present invention will be described in more detail with reference to the attached drawings.

[0035] FIG. 1 is a schematic diagram illustrating a battery active disassembly device according to one embodiment of the present invention.

[0036] Referring to FIG. 1, the battery active disassembly device (10) according to the present embodiment includes a first battery unit (100), a trigger unit (200), a second battery unit (300), and a switching element (400).

[0037] The first battery unit (100) provides driving for the driving element unit (140), and the driving element unit (140) is sufficient if it is a device that is driven by receiving power through the first battery unit (100). That is, the type of the driving element unit (140) is not limited, and it is sufficient if it receives power from the first battery unit (100).

[0038] The first battery unit (100) specifically includes a first packaging part (110), a first electrolyte (120), and a first internal unit (130).

[0039] First, the first internal unit (130) is located inside the first packaging unit (110) and, as a configuration for providing power, includes a first positive electrode (131), a first negative electrode (132), and a first current collector (133).

[0040] In this case, the first positive electrode (131) and the first negative electrode (132) can each be connected to the positive electrode of the driving element part (140).

[0041] Additionally, the first inner unit (130) may be configured to extend in one direction as shown in the illustration, but its structure is not limited and may be formed to be rolled into a round shape or formed in various other structures.

[0042] The first electrolyte (120) is an electrolyte material filled inside the first packaging part (110) and mediates ion transfer between the first anode (131) and the first cathode (132), and its type is not limited.

[0043] Meanwhile, the first battery unit (100) has been described as having a minimum configuration including the first internal unit (130) and the first electrolyte (120), but is not limited thereto, and it is sufficient as long as it can provide power to the driving element unit (140). That is, in addition to the components described above, additional components for configuring the battery may be included, and if necessary, the first internal unit (130) and the first electrolyte (120) may be replaced with other components.

[0044] The first packaging unit (110) covers the first internal unit (130) and the first electrolyte (120) and includes a first main packaging (111) and a first extension packaging (112).

[0045] The first main packaging (111) is formed to cover the first internal unit (130) and the first electrolyte (120), and the first extension packaging (111) is extended a predetermined length from one end of the first main packaging (111).

[0046] In this case, the first extension packaging (111) is illustrated in the drawing as extending from one end of the first main packaging (111), but the location where the first extension packaging (111) is extended is not limited.

[0047] In addition, the extension length of the first extension packaging (111) can be designed in various ways, but it is sufficient if it is formed to have a length that can be broken, such as by cutting, by the trigger unit (200) described later.

[0048] In order to facilitate such breakage, both the first extension packaging (112) and the first main packaging (111) can be formed from a material such as wax.

[0049] Furthermore, the first extension packaging (111) is connected to the first main packaging (111), so that the first electrolyte (120) included in the first main packaging (111) is naturally positioned in the first extension packaging (111).

[0050] The second battery unit (300) has substantially the same structure as the first battery unit (100). However, since the second battery unit (300) does not supply power to the driving element (140), it does not need to have a relatively large power supply capacity, and accordingly, it is manufactured with a smaller capacity than the first battery unit (300). Of course, the size or capacity of the second battery unit (300) can be varied.

[0051] That is, the second battery unit (300) also includes a second packaging part (310), a second electrolyte (320), and a second internal unit (330), and the second internal unit (330) includes a second positive electrode (331), a second negative electrode (332), and a second current collector (333).

[0052] At this time, the components constituting the second battery unit (300) are substantially identical to the components constituting the first battery unit (100) described above, except that their size or capacity is designed to be smaller; therefore, redundant descriptions are omitted.

[0053] Meanwhile, the second packaging portion (310) also includes a second main packaging (311) and a second extension packaging (312), wherein the second extension packaging (312) is formed to extend a predetermined length from one end of the second main packaging (311).

[0054] At this time, the second extension packaging (312) is positioned parallel to or adjacent to the first extension packaging (112). Thus, the first and second extension packagings (11, 31) can be damaged simultaneously through a single triggering via the trigger unit (200).

[0055] In order to facilitate such breakage, both the second extension packaging (312) and the second main packaging (311) can be formed from a material such as wax.

[0056] In the case of the second battery unit (300) above, in this embodiment, it provides a reference voltage, that is, it provides a reference voltage that performs a switching operation to provide power from the switching element (400) described later to the trigger unit (200).

[0057] The switching element (400) is connected between the first battery unit (100), the second battery unit (300), and the trigger unit (200), and may be a device such as an N-type MOSFET.

[0058] Specifically, as illustrated, in the switching element (400), the drain terminal (401) is connected to the first positive electrode (131) of the first battery unit (100), the source terminal (402) is connected to the first terminal (201) of the trigger unit (200), and the gate terminal (403) is connected to the first positive electrode (331) of the second battery unit (300).

[0059] In this case, as illustrated, the first cathode (132), the second cathode (332), and the second terminal (202) of the trigger unit (200) are grounded.

[0060] In this embodiment, with the terminals of the switching element (400) connected as described above, the switching element (400) operates as follows.

[0061] That is, by comparing the current voltage (Vm) of the first battery unit (100) with the reference voltage (Vr) provided to the second battery unit (300), if the current voltage (Vm) is greater than the reference voltage (Vr), the switching element (400) cuts off the power supply to the source terminal (402).

[0062] Thus, the power provided by the first battery unit (100) is provided only to the driving element unit (140).

[0063] In contrast, when the current voltage (Vm) of the first battery unit (100) and the reference voltage (Vr) provided to the second battery unit (300) are compared, and the current voltage (Vm) is smaller than the reference voltage (Vr), the switching element (400) is switched to supply power to the source terminal (402).

[0064] Thus, the power provided by the first battery unit (100) is provided to the trigger unit (200) through the switching element (400).

[0065] That is, as previously explained, the second battery unit (200) does not provide power to the trigger unit (200), but merely performs the role of providing a reference voltage (Vr) to determine whether the current voltage (Vm) of the first battery unit (100) is lower than a preset reference voltage (Vr).

[0066] At this time, the reference voltage (Vr) is a voltage that determines the point at which the first battery unit (100) is no longer used. If the current voltage (Vm) of the first battery unit (100) becomes lower than the reference voltage (Vr), the first battery unit (100) can be said to be in a state where it is difficult to use it further and it must be discarded.

[0067] Meanwhile, if the first battery unit (100) has a voltage lower than the reference voltage (Vr), although it is difficult to drive the driving element (140), there is still enough power remaining to supply power for heating the trigger unit (200).

[0068] That is, the reference voltage (Vr) can be pre-set to a voltage such that it makes driving the driving element part (140) impossible but enables heating of the trigger unit (200).

[0069] As described above, when the voltage of the first battery unit (100) decreases below the reference voltage (Vr), the switching element (400) supplies power from the first battery unit (100) to the trigger unit (200), and accordingly, the trigger unit (200) heats up according to the supply of power.

[0070] At this time, the trigger unit (200) may be, for example, a shape memory alloy (SMA), and when heated according to the supply of power, its shape is restored and deformed.

[0071] An example of damage to the first battery unit (100) caused by the shape restoration of the trigger unit (200) is described as follows.

[0072] FIGS. 2a and FIGS. 2b are schematic diagrams illustrating the disassembled state of the battery active disassembly device of FIG. 1.

[0073] That is, as shown in FIG. 2a, the trigger unit (200) may be formed as a wire that wraps around the outer surface of the first extension packaging (112). Additionally, the first extension packaging (112) may be formed of a wax material together with the first main packaging (111).

[0074] As previously described, the trigger unit (200) is restored to its shape and deformed when heated by the supply of power. At this time, the shape that is restored and deformed can be designed in various ways, but in the case of this embodiment, the wire-shaped trigger unit (200) can be restored in a form in which its length is reduced.

[0075] Accordingly, as shown in FIG. 2b, when power is supplied to the trigger unit (200) and the trigger unit (200) is heated, the wire-shaped trigger unit (200) is shortened in length. Additionally, when the length of the trigger unit (200) is shortened, the length of the wire wound around the outer surface of the first extension package (112) is shortened, and accordingly, the wire cuts the first extension package (112).

[0076] In particular, since the first extension packaging (112) is formed of a wax material, cutting by the wire can be relatively easy.

[0077] Thus, when the first extension packaging (112) is cut by the trigger unit (200), the first electrolyte (120) located inside the first battery unit (100) leaks out through the damaged portion of the first extension packaging (112), and at the same time, foreign substances such as rainwater present outside flow into the interior of the first battery unit (100).

[0078] Accordingly, the first electrolyte (120) located inside the first battery unit (100) leaks out and disappears, and if the first electrolyte (120) is an eco-friendly material, it can be naturally disposed of without causing harm to the environment.

[0079] Additionally, if the first internal unit (130) is made of a material that decomposes at a relatively low pH concentration, such as rainwater, the first internal unit (130) can also naturally decompose as the rainwater is supplied into the interior of the first battery unit (100).

[0080] Accordingly, the first battery unit (100) is permanently damaged and, since it decomposes in an environmentally friendly manner during this damage process, the impact on the environment is minimized and it can be naturally disposed of.

[0081] The physical damage to the battery unit of the trigger unit (200) described above can be applied in the same way to the battery active disassembly device (10) in FIG. 1.

[0082] That is, referring again to FIG. 1, the trigger unit (200) may have a wire shape that wraps the first extension packaging (112) and the second extension packaging (312).

[0083] Accordingly, when no separate power is supplied to the trigger unit (200), the trigger unit (200) maintains its shape while wrapping the first extension packaging (112) and the second extension packaging (312) as shown in FIG. 1.

[0084] However, as previously explained, when power is supplied to the trigger unit (200) by switching control by the switching element (400), the trigger unit (200) is heated.

[0085] At this time, when the trigger unit (200) is heated and deformed so that its length is reduced and its shape is restored, the trigger unit (200) naturally cuts and breaks the first extension packaging (112) and the second extension packaging (312) as indicated by the arrow.

[0086] Thus, as described with reference to FIG. 2b, the first electrolyte (120) leaks out through the damaged first extension packaging (112), and at the same time, foreign substances such as rainwater flow into the interior of the first battery unit (100) and perform decomposition on the constituent material such as the first internal unit (130).

[0087] Likewise, the second electrolyte (320) leaks out through the damaged second extension packaging (312), and at the same time, foreign substances such as rainwater flow into the interior of the second battery unit (300) and perform decomposition on the constituent material such as the second internal unit (330).

[0088] As described above, by restoring the shape of the trigger unit (200), the battery active disassembly device (10) can be rapidly and environmentally disposed of by itself.

[0089] FIG. 3 is a schematic diagram illustrating a battery active disassembly device according to another embodiment of the present invention.

[0090] The battery active disassembly device (20) according to the present embodiment is substantially the same as the battery active disassembly device (20) described with reference to FIG. 1, except for the structure of the trigger unit (210), so the same reference numbers are used for the same components and redundant descriptions are omitted.

[0091] Referring to FIG. 3, in the battery active disassembly device (20) according to the present embodiment, the trigger unit (210) is located in the space between the first extension package (112) and the second extension package (312). That is, the trigger unit (210) can be located in a wire shape, rolled along the mutually facing inner surfaces of the first extension package (112) and the second extension package (312).

[0092] In addition, the trigger unit (210) is heated when power is supplied to the trigger unit (210) by the switching control of the switching element (400), just like the trigger unit (200) described above.

[0093] However, in this embodiment, the trigger unit (210) may be deformed so that its length increases when heated and its shape is restored.

[0094] Accordingly, the trigger unit (210) located in the space between the first extension package (112) and the second extension package (312) has its wound radius increased as its length increases, as indicated by the arrow, and eventually cuts and breaks the first extension package (112) and the second extension package (312).

[0095] As a result of such damage, both the first battery unit (100) and the second battery unit (300) are naturally and environmentally decomposed, just as in the active decomposition device (10) described above.

[0096] Meanwhile, the trigger unit (200, 210) described with reference to FIGS. 1 and FIGS. 3 exemplifies a shape that changes in radius while wound in a wire form, but is not necessarily limited thereto.

[0097] That is, the trigger unit may be formed in a three-dimensional shape such as a square block, and its shape may be deformed such that the total volume increases or decreases upon heating. Ultimately, the trigger unit is sufficient if it has a structure that damages the first extension packaging (112) and the second extension packaging (312) as its shape is deformed by heating, and the shape of the structure is not limited.

[0098] FIG. 4 is a schematic diagram illustrating a battery active disassembly device according to another embodiment of the present invention.

[0099] The battery active disassembly device (30) according to the present embodiment is substantially the same as the battery active disassembly device (10) described in FIG. 1, except for the power supply role of the second battery unit (500) and the switching state of the switching element (410) accordingly; therefore, the same reference numbers are used for the same components and redundant descriptions are omitted.

[0100] Referring to FIG. 4, in the case of the battery active disassembly device (30) according to the present embodiment, first, the second battery unit (500) may be a battery unit capable of supplying power to the trigger unit (200).

[0101] At this time, the second battery unit (500) includes a second packaging part (510), a second electrolyte (520), and a second internal unit (530), each of which is substantially identical to the second packaging part (310), the second electrolyte (320), and the second internal unit (330) of the second battery unit (300) described with reference to FIG. 1. Accordingly, a description of the overlapping structure is omitted.

[0102] However, the second battery unit (500) is an additional battery for driving the trigger unit (200) and directly supplies a predetermined power to the trigger unit (200) according to the switching control of the switching element (410).

[0103] The switching element (410) is connected between the first battery unit (100), the second battery unit (500), and the trigger unit (200), and may be a device such as a P-type MOSFET.

[0104] Specifically, as illustrated, in the switching element (410), the drain terminal (411) is connected to the first positive electrode (131) of the first battery unit (100), the source terminal (412) is connected to the first terminal (201) of the trigger unit (200), and the gate terminal (413) is connected to the first positive electrode (531) of the second battery unit (500).

[0105] In this embodiment, with the terminals of the switching element (410) connected as described above, the switching element (410) operates as follows.

[0106] That is, by comparing the current voltage (Vm) of the first battery unit (100) with the voltage (Vr´) of the second battery unit (500), if the current voltage (Vm) is greater than the voltage (Vr´) of the second battery unit (500), the switching element (410) cuts off the power supply from the gate terminal (413) to the source terminal (412).

[0107] Accordingly, the voltage (Vr´) of the second battery unit (500) is not supplied to the trigger unit (200).

[0108] In contrast, when the current voltage (Vm) of the first battery unit (100) and the voltage (Vr´) of the second battery unit (500) are compared, and the current voltage (Vm) is smaller than the voltage (Vr´) of the second battery unit (500), the switching element (410) is switched so that power is supplied from the gate terminal (413) to the source terminal (412).

[0109] Accordingly, the voltage (Vr´) of the second battery unit (500) is supplied directly to the trigger unit (200).

[0110] At this time, the voltage (Vr') of the second battery unit (500) can ultimately be a voltage that determines the point at which the first battery unit (100) is used up, and if the first battery unit (100) is lower than the voltage (Vr'), it can be said that driving the driving element (140) is impossible. That is, the voltage (Vr') of the second battery unit (500) must be pre-set considering the driving state of the driving element (140).

[0111] However, the trigger unit (200) must be sufficiently heated through the voltage (Vr´) of the second battery unit (500), and the heating state of the trigger unit (200) must be designed with this in mind.

[0112] As described above, when the voltage (Vm) of the first battery unit (100) decreases compared to the voltage (Vr´) of the second battery unit (500), power is directly supplied from the second battery unit (500) to the trigger unit (200), thereby heating the trigger unit (200).

[0113] Furthermore, the shape restoration resulting from the heating of the trigger unit (200), and the resulting damage such as cutting of the first extension packaging (112) and the second extension packaging (512), are as described above.

[0114] As described above, by configuring the switching element to perform various switching operations, it is possible to design the battery so as to induce optimal battery disassembly by considering the operating state of the battery or the environment in which the battery is used.

[0115] FIG. 5 is a schematic diagram illustrating a battery active disassembly device according to another embodiment of the present invention.

[0116] The battery active disassembly device (40) according to the present embodiment is substantially the same as the battery active disassembly device (10) described with reference to FIG. 1, except that a sensor unit (600) is additionally provided; therefore, the same reference numbers are used for identical components and redundant descriptions are omitted.

[0117] Referring to FIG. 5, in the battery active disassembly device (40) according to the present embodiment, the sensor unit (600) is connected between the switching element (400) and the trigger unit (200).

[0118] That is, the sensor unit (600) includes a sensor section (610) and a switch section (620), wherein the switch section (620) is connected at one end to the source terminal (402) of the switching element (400) and at the other end to the first terminal (201) of the trigger unit (200).

[0119] Thus, when the switch unit (620) is in the ON state, the power of the first battery unit (100) provided through the source terminal (402) is supplied to the trigger unit (200). However, when the switch unit (620) is in the OFF state, the power of the first battery unit (100) provided through the source terminal (402) is not supplied to the trigger unit (200).

[0120] That is, even if it is determined through comparison with the reference voltage (Vr) that the residual voltage (Vm) of the first battery unit (100) is lower than the reference voltage (Vr), if the switch unit (620) is in the OFF state, the power of the first battery unit (100) is not supplied to the trigger unit (200), and accordingly, the trigger unit (200) is not heated and remains in a state where its shape is not restored.

[0121] The ON / OFF operation of the above switch unit (620) is performed based on the sensing signal of the above sensor unit (610).

[0122] For example, the sensor unit (610) may be a humidity sensor. If the humidity of the surrounding environment sensed by the sensor unit (610) is relatively high, making it difficult for the trigger unit (200) to heat up, the sensor unit (610) turns off the switch unit (620). Thus, power waste in a state where it is difficult to heat up the trigger unit (200) by unnecessarily supplying power in a relatively high humidity environment can be minimized.

[0123] That is, the sensor unit (610) determines whether the humidity of the surrounding environment corresponds to a range in which the trigger unit (200) can be heated, and controls the operation of the switch unit (620).

[0124] Meanwhile, although the sensor unit (610) is exemplified as a humidity sensor, the sensor unit (610) may, unlike this, be a temperature sensor or a gas sensor, or be a sensor that measures various other surrounding environmental conditions.

[0125] Thus, based on information about the surrounding environment in which the active disassembly device (40) is used, the trigger unit (200) can be heated in a more suitable environment to induce disassembly of the active disassembly device (40) more quickly and effectively.

[0126] According to the embodiments of the present invention as described above, when the use of the battery ends, artificial permanent damage can be caused to induce rapid and effective decomposition in the natural environment.

[0127] That is, a trigger unit induced to return to its original shape using a shape memory alloy can apply a physical impact to the battery unit, thereby inducing permanent damage to the battery unit and rapidly and effectively inducing self-decomposition.

[0128] In this case, the trigger unit returns to its original shape simply by being heated with power, and the battery unit may be designed to receive physical impact as the trigger unit returns to its original shape. That is, the battery unit includes a wax material and an extension packaging to which the trigger unit is fixed, and the trigger unit can induce permanent damage to the battery unit by breaking the extension packaging through deformation.

[0129] Meanwhile, regarding the power supply for heating the trigger unit, the second battery unit may provide a reference voltage to determine the timing of power supply to the trigger unit, or alternatively, the second battery unit may directly supply power to the trigger unit. Furthermore, since the power supply to the trigger unit is controlled through a switching element, the power supply to the trigger unit can be controlled through a circuit containing a relatively simple switching element.

[0130] In addition, if the surrounding environment is not suitable for heating the trigger unit through the sensor unit, effective heating of the trigger unit can be induced by cutting off the unnecessary power supply.

[0131] Although the present invention has been described above with reference to preferred embodiments, those skilled in the art will understand that various modifications and changes can be made to the invention without departing from the spirit and scope of the invention as set forth in the following claims.
