[0061] Figure 1 includes front and top perspective views of a toy system 30. In certain embodiments, the toy system 30 includes a container 32 forming a receptacle 56 sized and shaped to receive a toy or doll 48 therein according to a preferred embodiment of the present invention. In certain embodiments, the container 32 has a top opening 46. The doll 48 is shown inside the container 32 and after removal from the container 32. In certain embodiments, the container 32 is shaped like a cauldron. Of course, the shape of the container 32 is not limited to being round and can have any other shape (e.g., square, oblong, egg-shaped, cylindrical, etc.). In other embodiments, the container 32 includes a removable cover or top structure. [0062] Figure 2 is a partially transparent front view of the container 32 from Figure 1 showing a carriage 34. In certain embodiments, the carriage 34 is disposed within the container 32. In certain embodiments, at least a portion of the electronics for the toy system 30 are located in the carriage 34. In the illustrated embodiments, at least some of the electronics are located in the center of the container 32. In certain embodiments, at least some of the electronics are located between the walls of the container 32. [0063] In certain embodiments, the carriage 34 is disposed in the receptacle 56 and rotatable about an axis 36 between a first position 38 and a second position 40 (see Figure 12). In certain embodiments, the carriage 34 has a first receiving space 42 and a second receiving space 44 (see Figure 12). In certain embodiments, the first receiving space 42 is accessible through the top opening 46 when the carriage 34 is in the first position 38 and inaccessible through the top opening 46 when the carriage 34 is in the second position 40. In certain embodiments, the second receiving space 44 is accessible through the top opening 46 when the carriage 34 is in the second position 40 and inaccessible through the top opening 46 when the carriage 34 is in the first position 38. In certain embodiments, the toy or doll 48 is disposed in the second receiving space 44. [0064] In certain embodiments, the container 32 is filled with a liquid. For example, in certain embodiments, the container 32 is turned on and filled with water using a measuring jug. In certain embodiments, the container 32 turns on in response to the water activating one or more water sensors 108 in the first receiving space 42 (see Figure 13). In certain embodiments, one or more fizzes or water soluble items are added to the water. In certain embodiments, the container 32 is tapped by a wand 100 on a side of the container 32 (see Figure 17). The water can be stirred. In certain embodiments, the tapping causes the container 32 to emit lights and/or sound. In certain embodiments, the wand 100 lights up when the wand 100 is placed inside the container 32. In certain embodiments, power is wirelessly transferred from the container 32 to the wand 100. [0065] In certain embodiments, the toy system 30 can include a fog system 62 configured to generate fog within the container 32. In certain embodiments, the fog generated by the fog system 62 obfuscates the first receiving space 42. [0066] Figure 3 is a cross-section view of the cauldron 32 and carriage 34 from Figure 2 and shows, for example, a top side of the fog system 62. In certain embodiments, the carriage 34 comprises one or more printed circuit boards (PCB) 37. Figure 4 is a cross-section view of the container 32 and carriage 34 from Figure 2 and shows a bottom side of the fog system 62. [0067] In certain embodiments, the fog system 62 comprises a heater coil 64 and a fan 66. In certain embodiments, the fog system 62 further comprises a tube filled with fog fluid. In certain embodiments, the fog fluid is placed near the heater coil 64. In certain embodiments, the liquid is vegetable glycerin, propylene glycol, and water or mix thereof. In certain embodiments, when the toy system 30 is triggered to begin a fog play pattern, the heater coil 64 heats up and turns the liquid to fog. [0068] In certain embodiments, rolled up material is soaked in a fog fluid and placed near the heater coil 64. For example, in certain embodiments a soaked, wick is placed inside the heater coil 64. [0069] In certain embodiments, the fog system 62 comprises an ultrasonic atomizer. In certain embodiments, the ultrasonic atomizer is disposed in the first receiving space 42 below a liquid, for example, water. In certain embodiments, the ultrasonic atomizer employs piezoceramics to generate ultrasonic waves within the water. In certain embodiments, the waves propagate though the water and are focused on the surface of the water. At the surface of the water, the ultrasonic waves create an aerosol of fog from the water. In certain embodiments, the fog obfuscates the first receiving space 42. In certain embodiments, the fog covers a view of the first receiving space 42. In certain embodiments, the fog system 62 further comprises a high frequency AC supply. The high frequency AC supply can be configured to drive the ultrasonic atomizer. [0070] In certain embodiments, the ultrasonic atomizer need not be disposed in the first receiving space 42. For example, in certain embodiments, the ultrasonic atomizer is disposed in the carriage 34. For example, in certain embodiments, the ultrasonic atomizer is disposed in the carriage 34 and fed from the liquid in the first receiving space 42. In certain other embodiments, the ultrasonic atomizer is fed from a reservoir of liquid separate from the liquid in the first receiving space 42. In certain embodiments, the reservoir used to feed the ultrasonic atomizer is refillable by the user. In certain embodiments, air is drawn into the fog system 62, mixes with the aerosol of fog, and flows out of the fog system 62 as the fog. In certain embodiments, a scent is added to the liquid which is used to create the aerosol of fog. The scent can provide a distinctive smell to the aerosol of fog. [0071] In certain embodiments, the fan 66 draws air into the fog system 62 through one or more inlets 35. In certain embodiments, the drawn in air then flows through the heater coil 64, mixes with the gaseous fog, and flows out of the fog system 62 as the fog. In certain embodiments, the fog leaves the fog system 62 and then enters one or more ducts 110. In certain embodiments, the one or more ducts 110 are disposed in the carriage 34. In certain embodiments, the one or more ducts 110 are disposed in the carriage 34 and within the walls of the container 32. As will be explained with respect to Figure 22 and certain embodiments, the volume of the one or more ducts 110 can be selected to cause the fog leaving the heater coil 64 to cool before eventually exiting the carriage 34. [0072] In certain embodiments, at least a portion of the fog exits the carriage 34 via one or more exit holes 33 and flows into at least a portion of the container or cauldron 32. In certain embodiments, at least a portion of the fog eventually fills the cauldron 32 in a brief period of time. At least a portion of the fog will obfuscate the user from observing through the top opening 46 the rotation of the carriage 34 within the container 32. In certain embodiments, at least a portion of the fog generated by the fog system 62 covers a view of the first receiving space 42. For example, in certain embodiments, at least a portion of the fog will fill at least a sufficient volume between the liquid in the first receiving space 42 and the top opening 46 to obfuscate the user from observing through the top opening 46 the rotation of the carriage 34 within the container 32. In certain embodiments, at least a portion of the fog flows before, during, and/or after the carriage 34 rotates to the second position 40. [0073] In certain embodiments, at least a portion of the fog exits the carriage 34 from the bottom and/or top of the carriage 34 when the carriage 34 is in the first position 38. In certain embodiments, at least a portion of the fog flows from the carriage 34 into the first receiving space 42 and/or the second receiving space 44. [0074] In the embodiment illustrated in Figure 3, at least a portion of the fog exits the carriage 34 into the second receiving space 44 when the carriage 34 is in the first position 38. In certain embodiments, at least a portion of the fog continues to flow and fills the second receiving space 44. In certain embodiments, at least a portion of the fog flowing into the second receiving space 44 rises and flows into the first receiving space 42. In certain embodiments, at least a portion of the fog overflows from the second receiving space 44 into the first receiving space 42. In certain embodiments, once the second receiving space 44 is filled with fog, at least a portion of the fog rises around an outer perimeter of the carriage 34 and enters the first receiving space 42. In certain embodiments, at least a portion of the fog rises around an outer perimeter of the carriage 34 and enters the first receiving space 42 when the second receiving space 44 is not filled with fog. In certain embodiments, at least a portion of the fog flows before, during, and/or after the carriage 34 rotates to the second position 40. In certain embodiments, the rotation of the carriage 34 scoops at least a portion of the fog from the second receiving space 44 and brings the scooped fog to the top of the cauldron 32. [0075] In certain embodiments, at least a portion of the fog exits the carriage 34 into the first receiving space 42 when the carriage 34 is in the first position 38. In certain embodiments, at least a portion of the fog continues to flow and fills the first receiving space 42. In certain embodiments, at least a portion of the fog flowing into the first receiving space 42 flows down into the second receiving space 44. In certain embodiments, at least a portion of the fog overflows from the first receiving space 42 into the second receiving space 44. In certain embodiments, at least a portion of the fog flows before, during, and/or after the carriage 34 rotates to the second position 40. [0076] In certain embodiments, at least a portion of the fog exits the carriage 34 into both the first receiving space 42 and the second receiving space 44 when the carriage 34 is in the first position 38. In certain embodiments, at least a portion of the fog continues to flow and fills both the first receiving space 42 and the second receiving space 44. In certain embodiments, at least a portion of the fog flows before, during, and/or after the carriage 34 rotates to the second position 40. [0077] In certain embodiments, the toy system 30 comprises the one or more ducts 110. In certain embodiments, the geometry (e.g., size, volume, length, width, height, area, etc.) of the one or more ducts 110 can vary. For example, in certain embodiments, the geometry of the one or more ducts 110 can be selected to achieve a desirable decrease in the temperature of the fog. In certain embodiments, cooling the fog within the one or more ducts 110 can increase the density of the fog causing the fog to stay closer to the surface of the first receiving space 42 rather than immediately rise and exit the top opening 46. [0078] In certain embodiments, at least a portion of the one or more ducts 100 is located adjacent to the first receiving space 42. In certain embodiments, at least a portion of the one or more ducts 100 is located adjacent to a surface or wall that forms the first receiving space 42. When the first receiving space 42 is filled with room temperature water, a temperature of the wall will be lower than the temperature of the fog when the fog leaves the heater coil 64. Flowing the warmed fog through the duct 110 as well as adjacent to the filled first receiving space 42 further lowers the temperature of the fog. In this way, the density of the fog, which may have been less than the density of the surrounding air when exiting the heater coil 64, is increased to a value that is greater that the density of the air in the first receiving space 42. In certain embodiments, the fog system 62 includes one or more exit holes 33. In certain embodiments, the fog system 62 includes one or more exit holes 33. In certain embodiments, the one or more exit holes 33 can be located at any location within the container 32. In certain embodiments, the one or more exit holes 33 are distributed around a periphery of the carriage 34. [0079] In certain embodiments, the fan 66 is directly connected to the motor 58. In certain embodiments, the fan 66 forces air through a tube containing the heater coil 64 and the fog liquid. In certain embodiments, the fan 66 blows the fog from the heater coil 64, through the one or more ducts 110, and out of the one or more exit holes 33. [0080] Figure 5 is a front, right side view of the cauldron or container 32 showing one or more tension and/or torsion springs 52 configured to rotate the carriage 34 within the cauldron or container 32. In certain embodiments, the one or more tension and/or torsion springs 52 can be disposed on one or both sides of the carriage 34. In certain embodiments, when the carriage 34 is unlocked, the one or more tension and/or torsion springs 52 is biased to rotate the carriage 34 to the second position 40.

In certain embodiments, the head 96 comprises the capacitive sensor 95. In certain embodiments, the head 96 comprises an on/off switch 101. In certain embodiments, the on/off switch 101 is configured to turn the toy/doll 48 off or on. In certain embodiments, the head 96 comprises one or more batteries 103. In certain embodiments, the one or more batteries 103 are three batteries. In certain embodiments, the one or more batteries 103 are 1.5 volt button cell type batteries. In certain embodiments, the batteries are 3 LR44 batteries. Of course, other numbers of batteries as well as types of batteries can be employed with the toy system 30 while staying within the scope of this disclosure. In certain embodiments, the head 92 includes a recessed switch 106. [0096] Figure 17 includes perspective and exploded views of a wand 100 for use with the container 32 and toy/doll 48 of Figure 1. In certain embodiments, the wand 100 includes a magnet 102. In certain embodiments, the magnet 102 triggers a hall sensor in the toy 48 to cause the toy 48 to perform a predetermined action. In certain embodiments, the predetermined action is to make sounds and cause the gem on the head 92 to light up. In certain embodiments, the wand 100 includes an inductor. [0097] Figure 18 are schematic views of the container or cauldron 32 and the toy/doll 48 from Figure 1. A schematic of an embodiment of the wand 100 is also provided. In certain embodiments, the doll 48 can be wirelessly charged by the container 32. In certain embodiments, the container or cauldron 32 can include one or more of the motor 58, one or more LEDs 109, a water sensor 108, a piezo element 105, the fog system and power circuit 62, a microcontroller (MCU) 107, and a battery 74. In embodiments that include a wireless charging feature, the container 32 can further include a wireless power coil and driver circuit for the power coil. [0098] In certain embodiments, the toy 48 can include the capacitive sensor 95, a speaker 99, a microcontroller (MCU) 111, and one or more LEDs 113. In certain embodiments, the toy 48 can include a hall sensor 115. In embodiments that include a wireless charging feature, the toy 48 can further include a capacitor and a wireless power receiver. [0099] Figure 19 shows releasable connections for attaching the doll 48 to the carriage 34. In certain embodiments, the container 32 includes a switch for a user to select a mode of operation. In certain embodiments, the modes of operation include a birth mode, a spell mode, and an off mode. In certain embodiments, the user can select the birth mode when they first use the product. In certain embodiments, the birth mode can be repeatably used if the user wants to re-birth the toy 48. In certain embodiments, the toy system 30 is provided to the user initially in birth mode. In certain embodiments, the spell mode is selected after the user has already birthed the toy 48 but wants to make additional spells. [0100] In certain embodiments, the releasable connections are one or more plugs or retention clips 104. In certain embodiments, the toy 48 can be held in the container 32 using the one or more plugs or retention clips 104. In certain embodiments, the one or more plugs or retention clips 104 can project from the second receiving space 44 and fit into one or more holes in a body and/or head 96 of the toy 48. In certain embodiments, the one or more plugs or retention clips 104 can grip or hold the toy 48. For example, the one or more plugs or retention clips 104 can grip or pinch a portion (e.g., limb) of the toy 48. [0101] In certain embodiments, the head 96 can include a recessed switch 106 and cover. For example, when the one or more plugs or retention clips 104 are inserted into the hole, the recessed switch 106 will be pressed deactivating the toy 48. In certain embodiments, when the one or more plugs or retention clips 104 are removed from the hole, the recessed switch 106 will disengage from the one or more plugs or retention clips 104 and activate or turn on the toy 48. In certain embodiments, the one or more plugs or retention clips 104 can engage with the hole in a press fit manner and/or include a locking feature which inhibits the one or more plugs or retention clips 104 from falling out of the hole when the toy 48 is upside down and attached to the second receiving space 44 when the carriage 34 is in the second position 40. [0102] Figure 20 illustrates an exemplary method for playing with the toy system 30. The described methods are only exemplary. Any of the steps can be rearranged in order or omitted while staying within the scope of this disclosure. [0103] In certain embodiments, at Step A, water is added to the cauldron 32 to trigger the water sensor 108. Next, at step B, a water-soluble material is added to the water. In certain embodiments, the user can stir the potion and tap the side of the cauldron 32 with the wand 100 at step C. In certain embodiments, a user can add a fizz to the potion at step D. At step E, in certain embodiments, the user can stir the potion and tap the side of the cauldron 32 with the wand 100 to proceed. In certain embodiments, the user can write the name of their toy/doll 48 on the water- soluble paper at step F. In certain embodiments, the paper can be added to the potion at step G. In certain embodiments, at step H, the user can stir the potion and tap the side of the cauldron 32 with the wand 100 to proceed. In certain embodiments, the fog appears and then the toy/doll 48 is revealed at step I. In certain embodiments, the user can remove the toy/doll 48 from the cauldron 32 at step J. Once removed the gem in the head of the toy/doll 48 lights up at step K, in certain embodiments. In certain embodiments, petting the head 96 can trigger the capacitive sensor 95 at step L. In certain embodiments, the magnet in the wand 100 can trigger a hall sensor 115. In certain embodiments, the toy/doll 48 can be clipped to the cauldron 32 to receive wireless power. [0104] Another exemplary method of play includes the toy system 30 first being activating by water contacting the first receiving space 42. Next, the user adds one or more fizzes and water-soluble items to make a potion in the first receiving space 42. The user taps the container 32 with the wand 100 to progress through the potion process. The container 32 lights up and makes sounds. The container 32 releases fog and the carriage 34 turns to the second position 40 revealing the toy 48. An end of the wand 100 can light up when placed near the container 32. In certain embodiments that include wireless charging, the container 32 comprises an induction coil. The induction coil can activate the wand 100. The wand 100 can trigger the hall sensor in the toy 48 to cause the toy 48 to make sounds and the gem on its head to light up. When the cap sensor 95 in the toy 48 is activated, the toy 48 can also broadcast sound and emit light. In certain embodiments, the toy 48 is charged using wireless power transfer from the induction coil in the container 32. [0105] Figure 21 illustrates views of an embodiment of a fog fluid refill aperture 72. In certain embodiments, the opening 72 for refilling the fog system 62 with the fog liquid has a shape that matches a shape of the refill bottle 117. In this way, the refill bottle 117 has a corresponding shape nozzle 119 to the shape of the opening 72. In the illustrated embodiment, the opening 72 has a cross-shape 119 with a maximum diameter that prohibits filling the fog system 62 through the opening 72 with typical household bottles or syringes. Of course, the shape of the opening 72 and the nozzle 119 of the refill bottle 117 need not be cross-shaped. Other shapes fall within the scope of the disclosure. [0106] Figure 22 illustrates views of an embodiment of the duct 110 for the fog system 62. In the illustrated embodiment, at least a portion of the duct 110 is disposed in the carriage 34. In certain embodiments, the volume of the duct 110 is large enough to allow time for the fog to cool before exiting the duct 110 and the carriage 34. An exemplary volume for the duct 110 is illustrated in Figure 22. [0107] In certain embodiments, the fog leaves the fog system 62 and then enters the duct 110 in the carriage 34. In certain embodiments, the volume of the duct 110 is selected to cause the fog leaving the heater coil 64 to cool before eventually exiting the carriage 34 and entering the first receiving space 42. In certain embodiments, the geometry (e.g., size, volume, length, width, height, area, etc.) of the one or more ducts 110 can vary. For example, in certain embodiments, the geometry of the one or more ducts 110 can be selected to achieve a desirable decrease in the temperature of the fog. In certain embodiments, cooling the fog within the one or more ducts 110 can increase the density of the fog causing the fog to stay closer to the surface of the first receiving space 42 rather than immediately rise and exit the top opening 46. [0108] In the illustrated embodiment, the duct 110 is located adjacent to the first receiving space 42. For example, in the illustrated embodiment, the duct 110 is located adjacent to a surface or wall that forms the first receiving space 42. In certain embodiments, when the first receiving space 42 is filled with room temperature water, a temperature of the wall will be lower than the temperature of the heated fog when the fog leaves the heater coil 64. In certain embodiments, flowing the warmed fog through the duct 110 as well as adjacent to the filled first receiving space 42, further lowers the temperature of the fog. In this way, the density of the fog, which may have been less than the density of the surrounding air when exiting the heater coil 64, is increased to a value that is greater that the density of the surrounding air. In certain embodiments, the fog system 62 includes one or more exit holes 33. In certain embodiments, the one or more exit holes 33 can be distributed around a periphery of the carriage 34 to evenly distribute the fog within the container 32. [0109] Figure 23 illustrates views of an embodiment of an enclosure 68 for allowing items other than the doll or toy 48 to be revealed. In certain embodiments, the enclosure 68 includes a base 123 and a cover 121. In the illustrated embodiment, the cover 121 is hinged to the base 123 and can be opened and closed relative to the base 123 to allow the user to access an interior of the enclosure 68. [0110] In certain embodiments, the enclosure 68 is configured to be secured in the second receiving space 44. For example, the enclosure 68 can include one or more receptacles configured to receive the one or more posts or retention clips 104 that extend from the second receiving space 44. In this way, the enclosure 68 stays connected to the second receiving space 44 when the carriage 34 is upside down in the first position 38. The disclosure is not limited to the illustrated embodiment and can instead include any other fastener known to a person having ordinary skill in the art. Terminology [0111] Although certain embodiments and examples are disclosed herein, inventive subject matter extends beyond the examples in the specifically disclosed embodiments to other alternative embodiments and/or uses, and to modifications and equivalents thereof. Thus, the scope of the claims appended hereto is not limited by any of the particular embodiments described above. For example, in any method or process disclosed herein, the acts or operations of the method or process may be performed in any suitable sequence and are not necessarily limited to any particular disclosed sequence. Various operations may be described as multiple discrete operations in turn, in a manner that may be helpful in understanding certain embodiments; however, the order of description should not be construed to imply that these operations are order dependent. Additionally, the structures, systems, and/or devices described herein may be embodied as integrated components or as separate components. For purposes of comparing various embodiments, certain aspects and advantages of these embodiments are described. Not necessarily all such aspects or advantages are achieved by any particular embodiment. Thus, for example, various embodiments may be carried out in a manner that achieves or optimizes one advantage or group of advantages as taught herein without necessarily achieving other aspects or advantages as may also be taught or suggested herein. [0112] Features, materials, characteristics, or groups described in conjunction with a particular aspect, embodiment, or example are to be understood to be applicable to any other aspect, embodiment or example described in this section or elsewhere in this specification unless incompatible therewith. All of the features disclosed in this specification (including any accompanying claims, abstract and drawings), and/or all of the steps of any method or process so disclosed, may be combined in any combination, except combinations where at least some of such features and/or steps are mutually exclusive. The protection is not restricted to the details of any foregoing embodiments. The protection extends to any novel one, or any novel combination, of the features disclosed in this specification (including any accompanying claims, abstract and drawings), or to any novel one, or any novel combination, of the steps of any method or process so disclosed. [0113] Furthermore, certain features that are described in this disclosure in the context of separate implementations can also be implemented in combination in a single implementation. Conversely, various features that are described in the context of a single implementation can also be implemented in multiple implementations separately or in any suitable subcombination. Moreover, although features may be described above as acting in certain combinations, one or more features from a claimed combination can, in some cases, be excised from the combination, and the combination may be claimed as a subcombination or variation of a subcombination. [0114] Moreover, while operations may be depicted in the drawings or described in the specification in a particular order, such operations need not be performed in the particular order shown or in sequential order, or that all operations be performed, to achieve desirable results. Other operations that are not depicted or described can be incorporated in the example methods and processes. For example, one or more additional operations can be performed before, after, simultaneously, or between any of the described operations. Further, the operations may be rearranged or reordered in other implementations. Those skilled in the art will appreciate that in some embodiments, the actual steps taken in the processes illustrated and/or disclosed may differ from those shown in the figures. Depending on the embodiment, certain of the steps described above may be removed, others may be added. Furthermore, the features and attributes of the specific embodiments disclosed above may be combined in different ways to form additional embodiments, all of which fall within the scope of the present disclosure. Also, the separation of various system components in the implementations described above should not be understood as requiring such separation in all implementations, and it should be understood that the described components and systems can generally be integrated together in a single product or packaged into multiple products. [0115] For purposes of this disclosure, certain aspects, advantages, and novel features are described herein. Not necessarily all such advantages may be achieved in accordance with any particular embodiment. Thus, for example, those skilled in the art will recognize that the disclosure may be embodied or carried out in a manner that achieves one advantage or a group of advantages as taught herein without necessarily achieving other advantages as may be taught or suggested herein. [0116] For expository purposes, the term “horizontal” as used herein is defined as a plane parallel to the plane or surface of the floor or ground of the area in which the device being described is used or the method being described is performed, regardless of its orientation. The term “floor” floor can be interchanged with the term “ground.” The term “vertical” refers to a direction perpendicular to the horizontal as just defined. Terms such as “above,” “below,” “bottom,” “top,” “side,” “higher,” “lower,” “upper,” “over,” and “under,” are defined with respect to the horizontal plane. [0117] Conditional language used herein, such as, among others, “can,” “could,” “might,” “may,” “e.g.,” and the like, unless specifically stated otherwise, or otherwise understood within the context as used, is generally intended to convey that certain embodiments include, while other embodiments do not include, certain features, elements and/or steps. Thus, such conditional language is not generally intended to imply that features, elements and/or steps are in any way required for one or more embodiments or that one or more embodiments necessarily include logic for deciding, with or without other input or prompting, whether these features, elements and/or steps are included or are to be performed in any particular embodiment. The terms “comprising,” “including,” “having,” and the like are synonymous and are used inclusively, in an open-ended fashion, and do not exclude additional elements, features, acts, operations, and so forth. Also, the term “or” is used in its inclusive sense (and not in its exclusive sense) so that when used, for example, to connect a list of elements, the term “or” means one, some, or all of the elements in the list. [0118] Conjunctive language such as the phrase “at least one of X, Y, and Z,” unless specifically stated otherwise, is otherwise understood with the context as used in general to convey that an item, term, etc. may be either X, Y, or Z. Thus, such conjunctive language is not generally intended to imply that certain embodiments require the presence of at least one of X, at least one of Y, and at least one of Z. [0119] Language of degree used herein, such as the terms “approximately,” “about,” “generally,” and “substantially” as used herein represent a value, amount, or characteristic close to the stated value, amount, or characteristic that still performs a desired function or achieves a desired result. For example, the terms “approximately”, “about”, “generally,” and “substantially” may refer to an amount that is within less than 10% of, within less than 5% of, within less than 1% of, within less than 0.1% of, and within less than 0.01% of the stated amount. As another example, in certain embodiments, the terms “generally parallel” and “substantially parallel” refer to a value, amount, or characteristic that departs from exactly parallel by less than or equal to 15 degrees, 10 degrees, 5 degrees, 3 degrees, 1 degree, 0.1 degree, or otherwise.
