Description

Technical Field

[0001] The present disclosure generally relates to atomizing and vaporizing devices, and more particularly, to atomizer cores of electronic cigarette devices. Background Art

[0002] Electronic cigarettes (also known as "e-cigarettes") or vape devices can be used to deliver nicotine, flavors, chemicals, and other substances. These devices have many different names and come in many shapes, sizes, and device types. These devices can also be referred to as "e-cigarettes", "vapes", "vape pens", "dab pens", "dab rigs", "tank e-cigarettes", "mod e-cigarettes", "pod-mods", etc. Using an e-cigarette or vape product is sometimes referred to as "vaping".

[0003] Generally, traditional e-cigarette devices or vape devices include several basic components: a cartridge (also known as a reservoir or pod), an atomizer (or atomizer core) including a heating element, a power source (such as a battery), and a mouthpiece. The cartridge (or reservoir or pod) can hold various substances. The cartridge can be pre-loaded with these substances and sold together with or separately from the rest of the e-cigarette device. A particular substance is a liquid solution (sometimes referred to as "e-liquid" or "e-juice"). In a specific example, the liquid solution can contain different amounts of nicotine, flavorings, and / or other chemicals. Some traditional e-cigarette devices may not use a cartridge to hold the liquid solution. Instead, these e-cigarette devices include a reservoir built into the device for holding the liquid solution, and the liquid solution can be refilled into the reservoir. In many e-cigarette devices, the user's draw causes air to flow into the e-cigarette device. When air flows into the e-cigarette device, the resulting airflow will trigger an airflow sensor, thereby activating the heating element of the atomizer. The electrical heating element disposed within the atomization channel of the atomizer core begins to heat the e-liquid and generate an aerosol or vapor, which then flows out through the atomization channel under the drive of the airflow, and the resulting aerosol or vapor travels to the mouthpiece, where the aerosol or vapor is then inhaled by the user.

[0004] In traditional e-cigarette devices, the ceramic atomizing core has a single-layer structure. In terms of ceramics, "porosity" refers to the proportion of the volume of pores in the ceramic to the total volume of the ceramic, and the porosity of ceramics is generally between 20% and 65%. If the ceramic material of the core has a high porosity, the e-liquid guiding speed (i.e., the speed at which the e-liquid diffuses through the ceramic material) may be too high, leading to the problem of e-liquid leakage (i.e., since there is too much e-liquid in the core and it cannot be fully vaporized by the heating element, so the e-liquid flows out from the internal atomizing core). In addition, if the ceramic material of the core has a low porosity, the e-liquid supply will not be able to deliver the e-liquid to the heating element in time, resulting in "dry burning" inside the core. Therefore, an improved atomizing core for an e-cigarette device is needed. There is also a need for an improved atomizing core for an e-cigarette, which provides at least two layers in the atomizing core. There is also a need for an improved atomizing core for an e-cigarette device made of at least two layers of ceramic materials. There is also a need for an improved atomizing core for an e-cigarette device made of at least two layers of ceramic materials, where each layer has a different porosity from at least one other layer. There is a need for an improved atomizing core for an e-cigarette device with multiple layers of ceramic materials, where the layers have different porosities in a combined manner, so that the atomizing core has the advantages of high porosity and low porosity while avoiding the respective disadvantages of high porosity and low porosity. There is also a need for an improved atomizer core for an e-cigarette device, which is easier to manufacture, assemble, disassemble, adjust, and maintain.

[0005] The present utility model meets these requirements and provides other related advantages. Summary of the Utility Model

[0042] Embodiments of the present utility model will be described in detail hereinafter. Illustrations of the embodiments are shown in the accompanying drawings, in which like or similar reference numerals denote like or similar elements or elements having the same or similar functions. The embodiments described hereinafter with reference to the accompanying drawings are exemplary only and are intended to explain the present utility model and should not be construed as limiting the present utility model.

[0043] Referring to Figures 1-12 , embodiments of the present utility model provide an improved electronic cigarette device. As Figures 10-12As shown, the e-cigarette component 20 includes an atomizer component 200 and a battery component 300. The atomizer component 200 includes a housing 30, an upper cover 21, a smoke guide tube or atomization tube 22, an e-liquid guiding cotton 23, a ceramic atomizer core 24, an e-liquid storage chamber or cavity 31, an upper sealing seat 25, and a magnet 26. The magnet 26 is configured to engage the atomizer component 200 with the battery component 300. The battery component 300 includes a battery component body 27, a lower sealing seat 28, and a lower cover 29. The upper sealing seat 25 and the lower sealing seat 28 can be made of various materials, including but not limited to silicone, plastics (such as thermoplastics, thermoelastic plastics, thermosetting plastics, etc.), and their similar materials. The upper cover 21 and the lower cover 29 can be made of various materials, including but not limited to plastics (such as thermoplastics (such as cyclohexanedimethanol ethylene-modified poly(ethylene terephthalate) (PCTG), polycarbonate (PC), etc.), thermoelastic plastics, thermosetting plastics, etc.), silicone, and their similar materials. The atomizer component 200 and the battery component 300 are generally disposed within a housing sleeve 110. A part of the upper cover 21 is received within the housing sleeve 110 at the top end of the housing sleeve 110, and a part of the lower cover 29 is received within the housing sleeve 110 at the bottom end of the housing sleeve 110. A part of the upper cover 21 is received within the housing 30 at the top end of the housing 30, and a part of the upper sealing seat 25 is received within the housing 30 at the bottom end of the housing 30.

[0044] The ceramic atomization core 24 is disposed within the lower end portion of the atomization tube 22. Although Figures 10-12The use of the ceramic atomization core 24 is shown, but the ceramic atomization cores 124, 224, 324 are also applicable to the shown electronic cigarette assembly 20. The atomization tube 22 includes an internal generally cylindrical atomization channel 33. Although the atomization channel 33 is shown as generally cylindrical, the atomization channel 33 can have other shapes, including polygonal shapes, where the atomization channel can have three (3) or more sides. The internal atomization channel 33 is configured to provide a path for discharging aerosol or vapor to the upper cover 21. The aerosol or vapor is generated by heating and atomizing the e-liquid 400 through the ceramic atomization core 24. The upper cover 21 includes a mouthpiece portion 35 for engaging with the user's mouth during the use of the electronic cigarette assembly 20. The upper cover 21 further includes a channel or passage 36 that defines a path leading to the atomization tube 22, through which the aerosol or vapor passes through the upper cover 21 to reach the user's mouth for subsequent inhalation. One end of the channel or passage 36 is open at the mouthpiece portion 35, and one end of the channel or passage 36 opens to the atomization tube 22 through the guiding portion 40 of the upper cover 21. The open upper end portion of the atomization tube 22 extends into the guiding portion 40 of the upper cover 21 that communicates with the channel or passage 36, such that when the mouthpiece portion 35 communicates with the atomization channel 33, the vaporized liquid or smoke passes from the atomization tube 22 into the channel or passage 36 for subsequent inhalation by the user.

[0045] The atomization tube 22 includes at least one e-liquid inlet hole 221 corresponding to the ceramic atomization core 24. The e-liquid inlet hole 221 allows the e-liquid 400 in the e-liquid storage chamber or cavity 31 to enter the ceramic atomization core 24 and move towards the electric heating element 50 to be atomized into aerosol or vapor. The e-liquid 400 is transferred from the e-liquid storage chamber or cavity 31 to the e-liquid guiding cotton 23 through the e-liquid inlet hole 221 and finally enters the ceramic core 24. As described above, the "e-liquid" or "e-juice" 400 is a liquid solution that can contain various substances (alone or in combination) in different amounts, and these substances can include, but are not limited to, nicotine, flavorings, and / or other chemicals.

[0046] As Figures 1-6As shown, a first embodiment of the atomizing core 24 is illustrated. The ceramic atomizing core 24 is generally cylindrical and includes a first or inner layer 241 that is generally cylindrical, a second or outer layer 242 that is generally cylindrical, and an electric heating element 50 embedded in the atomizing core 24. The generally cylindrical first and second layers 241, 242 are generally concentric, adjacent, and aligned about a central axis (not shown). The first and second layers 241, 242 of the atomizing core 24 can be made of various ceramic materials, including but not limited to microporous ceramics having micropores. The micropores can generally range from about 8um to about 18um, preferably about 13um. The first layer 241 includes a porosity that is less than the porosity of the second layer 242 (i.e., the porosity of layers 241, 242 decreases sequentially from the outer layer (i.e., the second layer 242) to the inner layer (i.e., the first layer 241)). As a result, the absorption rate of the e-liquid in the first layer 241 is less than the absorption rate of the e-liquid in the second layer 242. Generally, when multiple ceramic layers are provided, the porosity decreases sequentially from the outside to the inside, and thus the rate decreases sequentially from the outside to the inside. The combination of at least two layers of ceramic materials with different porosities provides the advantages of high porosity and low porosity for the atomizing core 24, while avoiding the disadvantages of a conventional single-layer atomizing core, where the single layer has either high porosity or low porosity. It should be noted that the positions of the low-porosity layer and the high-porosity layer can be interchanged. As long as the two layers are combined, the goal of a reasonable absorption rate can be achieved.

[0047] As shown in the figure, the e-liquid is transferred from the e-liquid storage chamber 31 to the e-liquid guiding cotton 23 through the e-liquid inlet hole 221, then transferred to the second ceramic layer 242, and finally transferred to the first ceramic layer 241. By providing a multi-layer ceramic core to buffer and store the e-liquid, the e-liquid supply is made stable. The first advantage is that the e-liquid is absorbed through the outer ceramic layer (i.e., the second layer 242) with high porosity, so that the continuity of the e-liquid supply is good and no dry absorption event occurs, and the second advantage is that the e-liquid is absorbed through the inner ceramic layer (i.e., the first layer 241 with low porosity), so that the e-liquid leakage caused by the speed and angle of the e-liquid supply is reduced (if unavoidable).

[0048] The electric heating element 50 is arranged spirally. The electric heating element 50 includes an electric heating element body 248 and leads 249 extending from both ends of the electric heating element body 248. The bottom portion of the ceramic atomizing core 24 is disposed on the sealing seat 25. The sealing seat 25 includes a hole 253 through which the leads 249 of the ceramic core 24 extend into the channels of the battery assembly 300, and the leads 249 are riveted to the two poles of the battery assembly 300. A pair of electrodes 251 are made of various materials, including but not limited to conductive metals. The electrodes 251 are electrically connected to the leads 249 respectively.

[0049] The electric heating element 50 can have various forms, including but not limited to two (2) identical electric heating element bodies connected in parallel and brazed at both ends. In an illustrative embodiment, the size of the solder joints remaining after brazing shall not exceed 0.35 mm (since the larger the solder joint, the more likely a part of the solder joint will come into contact with adjacent heating coils of the electric heating element 50 and cause a short circuit).

[0050] Such as Figures 1-6As shown, a first embodiment of the atomization core 24 is shown. The ceramic atomization core 24 is generally cylindrical and includes a generally cylindrical first or inner layer 241, a generally cylindrical second or outer layer 242, and an electric heating element 50 embedded in the atomization core 24. The generally cylindrical first and second layers 241, 242 are generally concentric, adjacent, and aligned about a central axis (not shown). The first and second layers 241, 242 of the atomization core 24 can be made of various ceramic materials, including but not limited to microporous ceramics having micropores. The micropores can generally range from about 8um to about 18um, preferably about 13um. The first layer 241 includes a porosity that is less than the porosity of the second layer 242 (i.e., the porosity of the layers 241, 242 decreases sequentially from the outer layer (i.e., the second layer 242) to the inner layer (i.e., the first layer 241)). As a result, the rate of e-liquid absorption of the first layer 241 is less than the rate of e-liquid absorption of the second layer 242. Generally, when multiple ceramic layers are provided, the porosity decreases sequentially from the outside to the inside, and thus the rate decreases sequentially from the outside to the inside. The combination of at least two ceramic materials having different porosities provides the advantages of high porosity and low porosity for the atomization core 24 while avoiding the disadvantages of a conventional single-layer atomization core, where the single layer has either high porosity or low porosity. Similarly, it should be noted that the positions of the low-porosity layer and the high-porosity layer can be interchanged. As long as the two layers are combined, the goal of a reasonable absorption rate can be achieved. The shape of the ceramic atomization core 24 can be made by various methods, including but not limited to integrally forming by injection molding. As described above, the atomization core 24 has an internal generally cylindrical atomization channel (or central channel) 33, which is configured to provide a path for discharging aerosol or vapor into the atomization channel of the atomization tube 22. The ceramic atomization core 24 is a one-piece structure, where the first layer 241 and the second layer 242 are made of the same or different ceramic materials. In an alternative, the ceramic atomization core 24 can be made of separate first and second layers 241, 242 joined together, where the first and second layers 241, 242 can be made of the same or different microporous materials (such as ceramics). The outer surfaces of the first and second layers 241, 242 can be regarded as the surfaces through which e-liquid or e-liquid vapor is absorbed, while the e-liquid or vaporized e-liquid is discharged from the inner surface of the first layer 241 forming the atomization channel 33. The first and second layers 241, 242 are each at least 0.7mm. The thicknesses of the two layers can be the same or one layer can be thicker than the other. The thickness of the layer can be adjusted according to the required porosity of the layer.

[0051] As Figures 7A-7BAs shown, a second embodiment of the atomization core 124 is shown. The ceramic atomization core 124 is the same / similar to the atomization core 24, with the main difference being that the atomization core 124 includes a third layer 243, and the other parts are arranged in the same / similar manner. The atomization core 124 includes a first (inner) layer 241, a second (middle) layer, and a third (outer) layer 243. The layers 241, 242, 243 of the atomization core 124 can be made of various ceramic materials, including but not limited to microporous ceramics having micropores. The micropores can generally range from about 8 um to about 18 um, preferably about 13 um. The porosity of the ceramic material of the first layer 241 is greater than the porosity of the ceramic material of the second layer 242 and the porosity of the ceramic material of the third layer 243. That is, the absorption rate of the e-liquid of the first layer 241 is greater than the absorption rate of the e-liquid of the second layer 242 and the absorption rate of the e-liquid of the third layer 243. The ceramic atomization core 124 is a one-piece structure, where the first, second, and third layers 241, 242, 243 are made of the same or different ceramic materials. In an alternative, the ceramic atomization core 124 can be made of separate first, second, and third layers 241, 242, 243 joined together, where the first, second, and third layers 241, 242, 243 can be made of the same or different microporous materials (such as ceramics). The outer surfaces of the first, second, and third layers 241, 242, 243 can be regarded as the surfaces through which the e-liquid or e-liquid vapor is absorbed, while the e-liquid or vaporized e-liquid is discharged from the inner surface of the first layer 241 forming the atomization channel 133. Also, each of the first, second, and third layers 241, 242, 243 is at least 0.7 mm. The thicknesses of the first, second, and third layers can be the same, or one layer can be thicker or thinner than another layer. The thickness of the layer can be adjusted according to the required porosity of the layer.

[0052] As Figures 8A-8B shown, a third embodiment of the atomization core 224 is shown. The ceramic atomization core 224 includes a ceramic inner layer and an outer layer 1241, 1242, and is the same / similar to the generally cylindrical atomization core 24, with the main difference being that the inner layer 1241 does not have a consistent outer diameter between the top and the bottom, and the outer layer 1242 does not have a consistent inner diameter between the top and the bottom. The generally cylindrical first and second layers 1241, 1242 are generally concentric, adjacent, and aligned around a central axis (not shown). As Figures 8A-8BAs shown, the outer diameter of the first or inner layer 1241 is dimensioned and shaped to match the inner diameter of the second or outer layer 1242. The first or inner layer 1241 has a generally cylindrical uniform inner diameter between its top and bottom, but the outer diameter of the first or inner layer 1241 has a generally cylindrical first or lower portion 1241a (with a uniform diameter) and a generally cylindrical second or upper portion 1241b (with a uniform diameter), where the outer diameter of the first portion 1241a is greater than the outer diameter of the second portion 1241b. The second or outer layer 1242 has a generally cylindrical uniform outer diameter between its top and bottom, but the inner diameter of the second or outer layer 1242 has a generally cylindrical first or lower portion 1242a (with a uniform diameter) and a generally cylindrical second or upper portion 1242b (with a uniform diameter), where the inner diameter of the first portion 1242a is greater than the outer diameter of the second portion 1242b. The outer diameter of the first or lower portion 1241a of the first (or inner) layer 1241 is generally equal to the inner diameter of the first or lower portion 1242a of the second (or outer) layer 1242. The outer diameter of the second or upper portion 1241b of the first (or inner) layer 1241 is generally equal to the inner diameter of the second or upper portion 1242b of the second (or outer) layer 1242.

[0053] The first and second layers 1241, 1242 of the atomization core 224 can be made of various ceramic materials, including but not limited to microporous ceramics having micropores. The micropores can generally range from about 8um to about 18um, preferably about 13um. The first layer 1241 includes a porosity that is less than the porosity of the second layer 1242 (i.e., the porosity of the layers 1241, 1242 decreases in sequence from the outer layer (i.e., the second layer 1242) to the inner layer (i.e., the first layer 1241)). As a result, the rate of e-liquid absorption of the first layer 1241 is less than the rate of e-liquid absorption of the second layer 1242. The combination of at least two layers of ceramic materials with different porosities provides the advantages of high porosity and low porosity for the atomization core 224, while avoiding the disadvantages of a single-layer conventional atomization core, where the single layer has either high porosity or low porosity. In an alternative, the porosity of the first layer 1241 can be greater than the porosity of the second layer 1242.

[0054] The shape of the ceramic atomizing core 224 can be made by various methods, including but not limited to integrally forming by injection molding. Essentially, the inner layer or the first layer 1241 has an appearance of forming a recess or notch around the circumference of the upper portion 1241b of the atomizing core 224. The ceramic core 224 has a generally cylindrical atomizing channel (or central channel) 233 inside, which is configured to provide a path for discharging aerosol or vapor into the atomizing channel of the smoke guiding tube or the atomizing tube 22. The diameter of the atomizing channel 233 is defined by the inner diameter of the first layer (or inner layer) 1241. The ceramic atomizing core 224 is a one-piece structure, in which the first layer (or inner layer) 1241 and the second layer (or outer layer) 1242 are made of the same ceramic material. In an alternative, the ceramic atomizing core 124 can be made of separate first and second layers 1241, 1242 joined together, where the first and second layers 1241, 1242 can be made of the same or different microporous materials (such as ceramics). The outer surfaces of the first and second layers 1241, 1242 can be regarded as the surfaces through which the e-liquid or the vapor of the e-liquid is absorbed, while the e-liquid or the vaporized e-liquid is discharged from the inner surface of the first layer 1241 forming the atomizing channel 233. It should be noted again that the first and second layers 1241, 1242 are each at least 0.7 mm. The thicknesses of the two layers can be the same or one layer can be thicker than the other. The thickness of the layer can be adjusted according to the required porosity of the layer.

[0055] As Figures 9A-9B shown, a fourth embodiment of the atomizing core 324 is shown. The ceramic atomizing core 324 includes a ceramic inner layer and an outer layer 2241, 2242, and is the same / similar to the generally cylindrical atomizing core 24, with the main difference being that the atomizing core 324 includes two atomizing channels 1233, and a part of the inner layer 2241 forms a part of the outer surface of the atomizing core 324, and the other parts are arranged in the same / similar manner. There are two independent electric heating elements 50, and they are in a parallel circuit. Each atomizing channel 1233 has its own heating element 50. Each heating element 50 has a pair of wires 249. In an alternative, a single heating element 50 can be arranged around the two atomizing channels 1233.

[0056] In addition, the claimed utility model is not limited in size and can be configured in various sizes, where the same or similar operating principles as described above will be applied. In addition, the drawings of the specification (and the various components shown therein) should not be construed as being drawn to scale.

[0057] The terms used herein are for the purpose of describing particular example embodiments only and are not intended to be limiting. In this specification, the word "comprising" or variations thereof (such as "comprises" or "comprising") will be understood to mean the inclusion of the stated element, integer or step, or group of elements, integers or steps, but not the exclusion of any other element, integer or step, or group of elements, integers or steps. In other words, unless expressly stated to the contrary, an embodiment that "comprises" or "has" one or more elements with a particular property may include additional elements that do not have that property. In other words, the terms "comprising", "comprises", "including" and "has" are inclusive and thus specify the presence of the stated features, integers, steps, operations, elements and / or components, but do not preclude the presence or addition of one or more other features, integers, steps, operations, elements, components and / or their combinations. In other words, the use of "comprising", "includes", "has", "contains", "involves" and variations thereof means the inclusion of the items listed thereafter and additional items. Further, reference to "one embodiment" or "one implementation" is not to be construed as precluding the existence of additional embodiments or implementations that also incorporate the recited features. The term "exemplary" is intended to mean "an example of".

[0058] As used herein, the singular forms "a", "an" and "the" may be intended to include the plural forms as well, unless the context clearly dictates otherwise. In other words, an element or step recited in the singular and preceded by the word "a" or "an" should be understood to not necessarily exclude a plurality of elements or steps. Further, reference to "one embodiment" or "one implementation" is not to be construed as precluding the existence of additional embodiments or implementations that also incorporate the recited features. Thus, when introducing elements of aspects of the present disclosure or examples thereof, the articles "a", "an", "the" and "said" are intended to mean the presence of one or more elements. In other words, the indefinite articles "a", "an", "the" and "said" used in the specification and claims should be understood to mean "at least one" unless expressly stated to the contrary. The use of the phrase "at least" or "at least one" indicates the use of one or more elements or ingredients or amounts, as this use can achieve one or more desired purposes or results in embodiments of the present disclosure.

[0059] For various physical parameters, dimensions or quantities, the recited numerical values are only approximate values, and it is contemplated that values above / below the recited values specified as a parameter, dimension or quantity fall within the scope of the present disclosure, unless there is a clear contrary statement in the specification. It will be readily apparent to those skilled in the art that any range or value given herein can be extended or altered without losing the sought-after effect.

[0060] When an element or layer is referred to as being "joined to", "connected to", "coupled to", or "on" another element or layer, the element or layer can be directly joined to, connected to, or coupled to the other element or layer or on it, or intervening elements or layers may be present. In contrast, when an element is referred to as being "directly" "on", "directly joined to", "directly connected to", or "directly coupled to" another element or layer, no intervening elements or layers may be present. Other words used to describe the relationship between elements should be interpreted in a similar manner (e.g., "between" versus "directly between", "adjacent" versus "directly adjacent", etc.). As used herein, the term "and / or" includes any and all combinations of one or more of the associated listed items.

[0061] In the description of the present utility model, several means one or more, and multiple means more than two, greater than, less than, more than, etc. are understood not to include the number, while above, below, within, etc. are understood to include the number. If there is a description of the first item and the second item, it is only for distinguishing technical features and should not be understood as indicating or implying relative importance, the number of the indicated technical features, or the order of the indicated technical features.

[0062] In the description of the present utility model, it should be noted that the terms "installed", "connected", and "connection" (if any) should be understood in a broad sense unless otherwise specified and defined. For example, they can be a fixed connection, a detachable connection, or an integrated connection; they can be a mechanical connection or an electrical connection; and they can be a direct connection or an indirect connection through an intermediate medium, as well as a connection inside two elements. The specific meanings of the above terms in the present utility model can be understood by those of ordinary skill in the art in a specific situation.

[0063] Although various spatial and directional terms, such as "upper", "lower", "front", "rear", "left", "right", "vertical", "horizontal", "top", "bottom", "inner", "outer", "upper part", "lower part", etc. are used to describe the embodiments and implementations of the present disclosure, it should be understood that these terms are only used relative to the directions shown in the drawings. The orientation can be inverted, rotated or otherwise changed, such that if the structure is flipped 180 degrees, the top side becomes the bottom side, and if the structure is pivoted 90 degrees, the top side becomes the left side or the right side, etc. In other words, for the sake of convenience of description, spatially relative terms, such as "inner", "outer", "below", "beneath", "above", "lateral", "longitudinal", etc. may be used herein to describe the relationship of one element or feature to another element or feature shown in the drawings. In addition to the orientation depicted in the drawings, the spatially relative terms may be intended to include different orientations of the device in use or operation. For example, if the device in the drawing is flipped, an element described as "below" or "beneath" other elements or features will be oriented "above" the other elements or features. Thus, the exemplary term "below" can include both upward and downward orientations. The device may be otherwise oriented (rotated 90 degrees or other orientations), and the spatially relative descriptive terms used herein shall be interpreted accordingly.

[0064] In the description of the present utility model, it should be understood that the orientation or positional relationship indicated by the terms is based on the orientation or positional relationship shown in the drawings, which is only for the convenience of describing the present utility model and simplifying the description, and does not indicate or imply that the indicated device or element must have a specific orientation and be constructed and operated in a specific orientation. Therefore, these terms should not be construed as limiting the present utility model.

[0065] As used herein, a structure, limitation or element "configured to" perform a task or operation is specifically formed, constructed or adjusted structurally in a manner corresponding to that task or operation. For clarity and to avoid doubt, an object that can merely be modified to perform a task or operation is not "configured to" perform the task or operation used herein.

[0066] Although the 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 need not be limited to the specific features or acts described above. Rather, the above specific features and acts are disclosed as example forms of implementing the claims.

[0067] It should be understood that the above advantages and benefits may relate to one embodiment, or may relate to multiple embodiments. The embodiments are not limited to the embodiments that solve any or all of the described problems, or have any or all of the described advantages and benefits. It should also be understood that the reference to "one" item means one or more of those items.

[0068] Unless otherwise expressly specified, the order of performance or implementation of the operations in the examples of the disclosure shown and described herein is not necessary. That is, the operations may be performed in any order, unless otherwise expressly specified, and the examples of the present disclosure may include more or fewer operations than those disclosed herein. For example, it is contemplated that a particular operation may be performed before, simultaneously with, or after another operation (e.g., a different step, etc.) within the scope of aspects and embodiments of the present disclosure. In other words, unless expressly identified as the order of performance, the method steps, processes, and operations described herein should not be construed as necessarily requiring them to be performed in the particular order discussed or shown. It should also be understood that additional or alternative steps may be employed.

[0069] The phrase “one or more of the following: A, B, and C” means “at least one of A and / or at least one of B and / or at least one of C”. The phrase “and / or” as used in the specification and claims should be understood to mean “one or both” of the elements so combined, i.e., elements that are present together in some cases and separate in other cases. Multiple elements listed with “and / or” should be construed in the same manner, i.e., “one or more” of the elements so combined. Other elements may optionally be present in addition to those specifically identified by the “and / or” clause, whether or not related to those specifically identified. Thus, as a non-limiting example, in one embodiment, when used in conjunction with open-ended language such as “comprising”, a reference to “A and / or B” may refer only to A (optionally including elements other than B); in another embodiment, only to B (optionally including elements other than A); in yet another embodiment, to both A and B (optionally including other elements); and so on.

[0070] As used in the specification and claims, “or” should be understood to have the same meaning as “and / or” defined above. For example, when separating items in a list, “or” or “and / or” should be interpreted as inclusive, i.e., including at least one, but also including more than one of a plurality or series of elements, and optionally, additional unlisted items. Only terms expressly indicating the contrary, such as “only one” or “exactly one”, or when used in a claim, “consisting of”, will refer to including exactly one element of a plurality or series of elements. In general, the term “or” when preceded by an exclusive term such as “either of the two”, “one”, “only one”, or “exactly one” should be interpreted only as indicating an exclusive choice (i.e., “one or the other, but not both”). When used in a claim, “consisting essentially of” should have the ordinary meaning as used in the field of patent law.

[0071] As described above, as used in the specification and claims, referring to a list of one or more elements, the phrase "at least one" should be understood to mean at least one element selected from any one or more of the elements in the list of elements, but not necessarily including at least one of each specifically listed element in the list of elements, and not excluding any combination of the elements in the list of elements. This definition also allows that elements may optionally exist in addition to the elements specifically identified in the list of elements referred to by the phrase "at least one", whether or not related to those specifically identified elements. Thus, by way of non-limiting example, "at least one of A and B" (or equivalently, "at least one of A or B", or equivalently "A and / or B") may, in one embodiment, refer to at least one, optionally including more than one A, with no B present (and optionally including elements other than B); in another embodiment, at least one, optionally including more than one B, with no A present (and optionally including elements other than A); in yet another embodiment, at least one, optionally including more than one A, and at least one, optionally including more than one B (and optionally including other elements), and so on.

[0072] The use of ordinal numbers in the claims, such as "first", "second", "third", etc., to modify the claim elements themselves does not mean any priority, precedence or order of one claim element with respect to another claim element, or the chronological order in which the acts of a method are performed. Ordinal numbers are used merely as labels to distinguish one claim element having a particular name from another element having the same name (but using an ordinal number), to distinguish claim elements.

[0073] Having described the various aspects of the present disclosure in detail, it should be clear that modifications and variations can be made without departing from the scope of the aspects of the present disclosure as defined in the appended claims. Since various modifications can be made to the above-described structures, products and methods without departing from the scope of the present disclosure, all of the content included in the above description and shown in the drawings should be construed as illustrative and not restrictive.

[0074] It should be understood that the above description is intended to be illustrative and not restrictive. For example, the above embodiments (and / or aspects thereof) can be used in combination with each other. Additionally, many modifications can be made to adapt a particular situation or material to the teachings of the various embodiments of the present disclosure without departing from the scope of the present disclosure. Although the dimensions and types of the materials described herein are intended to define the parameters of the various embodiments of the present disclosure, these embodiments are in no way restrictive but are exemplary embodiments. Many other embodiments will be apparent to those of ordinary skill in the art upon reading the above description. Accordingly, the scope of the various embodiments of the present disclosure should be determined with reference to the appended claims and the full scope of equivalents of these claims. In the appended claims, the terms "comprising" and "in which" are used as the plain English equivalents of the corresponding terms "including" and "wherein". Additionally, the terms "first", "second", and "third", etc. are used merely as labels and are not intended to impose numerical requirements on their objects. Furthermore, the limitations of the following claims are not written in means-plus-function format and are not intended to be interpreted based on 35 U.S.C. § 112(f) unless and until such claim limitations expressly use the phrase "means for" followed by a function statement without further structure.

[0075] This written description uses examples to disclose the various embodiments of the present disclosure, including the best mode, and also enables those of ordinary skill in the art to practice the various embodiments of the present disclosure, including manufacturing and using any device or system and performing any combined method. The protectable scope of the various embodiments of the present disclosure is defined by the claims and may include other examples that occur to those of ordinary skill in the art. If these examples have structural elements that are not different from the literal language of the claims, or if these examples include equivalent structural elements that are not substantially different from the literal language of the claims, then these other examples are intended to be within the scope of the claims.
