     BACKGROUND 
     Field 
     The present disclosure relates to electronic vapor devices including self-contained articles including vapor precursors. 
     Description of Related Art 
     Some e-vapor devices include a first section coupled to a second section via a threaded connection. The first section may be a replaceable cartridge, and the second section may be a reusable fixture. The threaded connection may be a combination of a male threaded member on the first section and a female threaded receiver on the second section. The first section includes an outer tube (or housing) extending in a longitudinal direction and an inner tube within the outer tube. The inner tube may be coaxially positioned within the outer tube. The second section may also include the outer tube (or housing) extending in a longitudinal direction. The e-vapor device includes a central air passage defined in part by the inner tube and an upstream seal. Additionally, the e-vapor device includes a reservoir. The reservoir is configured to hold a vapor precursor and optionally a storage medium operable to store the vapor precursor therein. The reservoir is contained in an outer annulus between the outer tube and the inner tube. The outer annulus is sealed by the seal at an upstream end and by a stopper at a downstream end so as to prevent leakage of the vapor precursor from the reservoir. 
     SUMMARY 
     An e-vapor apparatus may include a pod assembly, a dispensing body configured to receive the pod assembly, and/or a vaporizer disposed in at least one of the pod assembly and the dispensing body. The pod assembly may include a vapor precursor compartment, a device compartment, and a vapor channel extending from the device compartment and traversing the vapor precursor compartment. The vapor precursor compartment is configured to hold a vapor precursor therein. The dispensing body includes a proximal portion and an opposing distal portion. The proximal portion includes a vapor passage and a through-hole. The vapor passage may extend from an end surface of the proximal portion to a side wall of the through-hole. The through-hole may be between the vapor passage and the distal portion of the dispensing body. The through-hole is configured to receive the pod assembly. The vaporizer may be disposed in at least one of the pod assembly and the dispensing body. The vapor precursor compartment of the pod assembly is configured to be in fluidic communication with the vaporizer during an operation of the e-vapor apparatus such that the vapor precursor from the vapor precursor compartment comes into thermal contact with the vaporizer. The vaporizer is configured to heat the vapor precursor to produce a vapor that passes through the pod assembly via the vapor channel. The through-hole of the dispensing body is configured to receive the pod assembly such that the vapor channel of the pod assembly is aligned with the vapor passage of the dispensing body so as to facilitate a delivery of the vapor through the vapor passage of the dispensing body. 
     The vapor precursor compartment of the pod assembly may surround the vapor channel. For example, the vapor channel may pass through a center of the vapor precursor compartment. 
     Alternatively, the vapor channel may be in a form of a pathway that is arranged along at least one sidewall of the vapor precursor compartment. For example, the vapor channel may be in a form of a conduit that is arranged in at least one corner of the vapor precursor compartment. The conduit may be arranged in at least two corners of the vapor precursor compartment and configured to converge at a position that is aligned with the vapor passage of the dispensing body when the pod assembly is received in the through-hole. 
     The vapor precursor compartment and the device compartment may be at opposite ends of the pod assembly. The device compartment of the pod assembly may include a memory device. The memory device may be coded with an electronic identity to permit at least one of an authentication of the pod assembly and a pairing of operating parameters specific to a type of the pod assembly when the pod assembly is inserted into the through-hole of the dispensing body. The memory device may also receive and store information such as operational parameters and usage history from the dispensing body. Once stored, such information in the memory device will remain intact even when the pod is detached from the dispensing body. 
     The pod assembly may include a side surface having at least one electrical contact. The dispensing body may be configured to perform at least one of supply power to and communicate with the pod assembly via the at least one electrical contact. The at least one electrical contact may be at an end of the pod assembly corresponding to the device compartment. 
     The dimensions of the through-hole correspond to dimensions of the pod assembly. The proximal portion of the dispensing body may include a mouthpiece that includes the vapor passage. The vapor channel may be between the mouthpiece and the device compartment when the pod assembly is inserted into the through-hole of the dispensing body. The e-vapor apparatus may further include an attachment structure on at least one of the side wall of the through-hole and a side surface of the pod assembly. The attachment structure is configured to engage and hold the pod assembly upon insertion into the through-hole of the dispensing body. The attachment structure enables the pod assembly to be inserted and extracted from the dispensing body by the adult vaper with ease. The attachment structure also aligns and secures the pod assembly in place in the dispensing body during normal use of the e-vapor apparatus. 
     A pod assembly for an e-vapor apparatus may include a vapor precursor compartment configured to hold a vapor precursor therein; a device compartment in fluidic communication with the vapor precursor compartment; and a vapor channel extending from the device compartment and traversing the vapor precursor compartment. The device compartment may include a vaporizer. The device compartment may also include a memory device. A side surface of the pod assembly may include at least one electrical contact.

     DETAILED DESCRIPTION 
     It should be understood that when an element or layer is referred to as being “on,” “connected to,” “coupled to,” or “covering” another element or layer, it may be directly on, connected to, coupled to, or covering the other element or layer or intervening elements or layers may be present. In contrast, when an element is referred to as being “directly on,” “directly connected to,” or “directly coupled to” another element or layer, there are no intervening elements or layers present. Like numbers refer to like elements throughout the specification. As used herein, the term “and/or” includes any and all combinations of one or more of the associated listed items. 
     It should be understood that, although the terms first, second, third, etc. may be used herein to describe various elements, components, regions, layers and/or sections, these elements, components, regions, layers, and/or sections should not be limited by these terms. These terms are only used to distinguish one element, component, region, layer, or section from another region, layer, or section. Thus, a first element, component, region, layer, or section discussed below could be termed a second element, component, region, layer, or section without departing from the teachings of example embodiments. 
     Spatially relative terms (e.g., “beneath,” “below,” “lower,” “above,” “upper,” and the like) may be used herein for ease of description to describe one element or feature&#39;s relationship to another element(s) or feature(s) as illustrated in the figures. It should be understood that the spatially relative terms are intended to encompass different orientations of the device in use or operation in addition to the orientation depicted in the figures. For example, if the device in the figures is turned over, elements described as “below” or “beneath” other elements or features would then be oriented “above” the other elements or features. Thus, the term “below” may encompass both an orientation of above and below. The device may be otherwise oriented (rotated 90 degrees or at other orientations) and the spatially relative descriptors used herein interpreted accordingly. 
     The terminology used herein is for the purpose of describing various embodiments only and is not intended to be limiting of example embodiments. As used herein, the singular forms “a,” “an,” and “the” are intended to include the plural forms as well, unless the context clearly indicates otherwise. It will be further understood that the terms “includes,” “including,” “comprises,” and/or “comprising,” when used in this specification, specify the presence of 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 groups thereof. 
     Example embodiments are described herein with reference to cross-sectional illustrations that are schematic illustrations of idealized embodiments (and intermediate structures) of example embodiments. As such, variations from the shapes of the illustrations as a result, for example, of manufacturing techniques and/or tolerances, are to be expected. Thus, example embodiments should not be construed as limited to the shapes of regions illustrated herein but are to include deviations in shapes that result, for example, from manufacturing. The regions illustrated in the figures are schematic in nature and their shapes are not intended to illustrate the actual shape of a region of a device and are not intended to limit the scope of example embodiments. 
     Unless otherwise defined, all terms (including technical and scientific terms) used herein have the same meaning as commonly understood by one of ordinary skill in the art to which example embodiments belong. It will be further understood that terms, including those defined in commonly used dictionaries, should be interpreted as having a meaning that is consistent with their meaning in the context of the relevant art and will not be interpreted in an idealized or overly formal sense unless expressly so defined herein. 
       FIG. 1  is a perspective view of a dispensing body of an e-vapor apparatus according to an example embodiment. Referring to  FIG. 1 , a dispensing body  104  of an e-vapor apparatus includes a frame portion that is connected to a body portion  118 . The frame portion includes a first frame  110  and a second frame  112 . The side walls  116  (e.g., inner side surfaces) of the first frame  110  and the second frame  112  define a through-hole  114 . The through-hole  114  is configured to receive a pod assembly (which will be subsequently discussed in detail). 
     Generally, an e-vapor apparatus may include the dispensing body  104 , a pod assembly inserted in the through-hole  114  of the dispensing body  104 , and a vaporizer disposed in at least one of the pod assembly and the dispensing body  104 . The pod assembly may include a vapor precursor compartment (e.g., liquid compartment), a device compartment, and a vapor channel. The vapor channel may extend from the device compartment and traverse the vapor precursor compartment. The vapor precursor compartment is configured to hold a vapor precursor (e.g., e-liquid) therein. A vapor precursor is a material or combination of materials that may be transformed into a vapor. For example, the vapor precursor may be a liquid, solid, and/or gel formulation including, but not limited to, water, beads, solvents, active ingredients, ethanol, plant extracts, natural or artificial flavors, and/or vapor formers such as glycerine and propylene glycol. 
     The dispensing body  104  includes a proximal portion and an opposing distal portion. The mouthpiece  108  is disposed at the proximal portion, while the end piece  120  is disposed at the distal portion. The proximal portion includes a vapor passage  106  and the through-hole  114 . The vapor passage  106  extends from an end surface of the proximal portion to the side wall  116  of the through-hole  114 . The vapor passage  106  is in the form of one or more passageways extending through the proximal portion of the dispensing body  104 . The through-hole  114  is between the vapor passage  106  and the distal portion of the dispensing body  104  (e.g., between the mouthpiece  108  and the body portion  118 ). 
     A vaporizer (which will be subsequently discussed in more detail) is disposed in at least one of the pod assembly and the dispensing body  104 . The vapor precursor compartment of the pod assembly is configured to be in fluidic communication with the vaporizer during an operation of the e-vapor apparatus such that the vapor precursor from the vapor precursor compartment comes into thermal contact with the vaporizer. The vaporizer is configured to heat the vapor precursor to produce a vapor that passes through the pod assembly via the vapor channel. The through-hole  114  of the dispensing body  104  is configured to receive the pod assembly such that the vapor channel of the pod assembly is aligned with the vapor passage  106  of the dispensing body  104  so as to facilitate a delivery of the vapor through the vapor passage  106  of the dispensing body  104 . 
       FIG. 2  is an exploded view of the dispensing body of  FIG. 1 . Referring to  FIG. 2 , the first frame  110  and the second frame  112  are configured to unite to form the frame portion of the dispensing body  104 . A number of options are available for uniting the first frame  110  and the second frame  112 . In an example embodiment, the first frame  110  is a female member, while the second frame  112  is a male member that is configured to engage therewith. Alternatively, the first frame  110  may be a male member, while the second frame  112  may be a female member that is configured to engage therewith. The engagement of the first frame  110  and the second frame  112  may be via a snap-fit, friction-fit, or slide-lock type arrangement, although example embodiments are not limited thereto. 
     The first frame  110  may be regarded as the front frame of the dispensing body  104 , and the second frame  112  may be regarded as the rear frame (or vice versa). Additionally, the proximal ends of the first frame  110  and the second frame  112 , when united, define the vapor passage  106  therebetween. The vapor passage  106  may be in the form of a single passageway that is in communication with the through-hole  114  defined by the side wall  116 . Alternatively, the vapor passage  106  may be in the form of a plurality of passageways that are in communication with the through-hole  114  defined by the side wall  116 . In such an example, the plurality of passageways may include a central passageway surrounded by peripheral passageways (or just several evenly spaced passageways). Each of the plurality of passageways may independently extend from the through-hole  114  to the proximal end surface of the frame portion. Alternatively, a common passageway may extend partly from the through-hole  114  and then branch into a plurality of passageways that extend to the proximal end surface of the frame portion. 
     The mouthpiece  108  is configured to slip onto the proximal end of the frame portion that defines the vapor passage  106 . As a result, the outer surface of the proximal end formed by the first frame  110  and the second frame  112  may correspond to an inner surface of the mouthpiece  108 . Alternatively, the proximal end defining the vapor passage  106  may be integrally formed as part of the mouthpiece  108  (instead of being a part of the frame portion). The mouthpiece  108  may be secured via a snap-fit type or other suitable arrangement. In an example embodiment, the mouthpiece  108  is a removable component that is intended to permit voluntary, recommended, or required replacement by an adult vaper. For instance, the mouthpiece  108  may, in addition to its intended functionality, provide a visual or other sensory appeal to the adult vaper. In particular, the mouthpiece  108  may be formed of an ornamental material (e.g., wood, metal, ceramic) and/or include designs (e.g., patterns, images, characters). Thus, the mouthpiece  108  may be customized so as to provide an expression of personality and individuality by an adult vaper. In other instances, the removable nature of the mouthpiece  108  may facilitate a recommended replacement due to the amount of usage or a required replacement due to wear over time or damage (e.g., chipped mouthpiece  108  caused by accidental dropping of e-vapor apparatus). 
     The lower ends of the first frame  110  and the second frame  112  opposite the proximal ends (that define the vapor passage  106 ) are configured to insert into the body portion  118 . To facilitate a secure fit, the outer surface of the lower ends of the first frame  110  and the second frame  112  may correspond to a receiving inner surface of the body portion  118 . Additionally, the lower ends of the first frame  110  and the second frame  112  may also define a groove therebetween to accommodate one or more wires that connect to one or more electrical contacts provided in the side wall  116  (e.g., lower surface of the side wall  116  opposite the vapor passage  106 ). A power source (e.g., battery) may also be provided in the groove to supply the requisite current through the wire(s). Alternatively, the power source may be provided in an available space within the body portion  118  between the inserted lower end of the frame portion and the end piece  120 . 
     A first button  122  and a second button  124  may be provided on the body portion  118  and connected to the corresponding circuitry and electronics therein. In an example embodiment, the first button  122  may be a power button, and the second button  124  may be a battery level indicator. The battery level indicator may display a representation of the amount of power available (e.g., 3 out of 4 bars). In addition, the battery level indicator may also blink and/or change colors to alert an adult vaper to recharge the e-vapor apparatus. To stop the blinking, an adult vaper may simply press the second button  124 . Thus, the button(s) of the e-vapor apparatus may have a control and/or display function. It should be understood that the examples with regard to the first button  122  and the second button  124  are not intended to be limiting and can have different implementations depending on the desired functionalities. Accordingly, more than two buttons (and/or of different shapes) may be provided in the same proximity or at a different location on the e-vapor apparatus. 
       FIG. 3  is a perspective view of the mouthpiece of  FIG. 2 . Referring to  FIG. 3 , the mouthpiece  108  may be an open-ended cap-like structure that is configured to slip onto the proximal end of the frame portion defining the vapor passage  106 . The mouthpiece  108  may have a wider base that tapers to a narrower top. However, it should be understood that example embodiments are not limited thereto. The mouthpiece  108  may also be shaped to better accommodate an adult vaper&#39;s mouth during inhalation of the vapor. For instance, one side of the mouthpiece  108  may be more linear, while the opposing side may be more curved. 
       FIG. 4  is a perspective view of the first frame of  FIG. 2 . Referring to  FIG. 4 , the first frame  110  includes a side wall  116  that defines a through-hole  114 . The first frame  110  is configured to unite with the second frame  112 , which also includes a side wall  116  defining a through-hole  114 . Because the combined through-hole  114  is configured to receive a pod assembly, the side walls  116  of the first frame  110  and the second frame  112  may form a relatively smooth and continuous surface to facilitate the insertion of the pod assembly. 
       FIG. 5  is a perspective view of the second frame of  FIG. 2 . Referring to  FIG. 5 , the second frame  112  is configured to unite with the first frame  110  such that the shape defined by the combined side walls  116  corresponds to the shape of the side surface of a pod assembly. In addition, an attachment structure (e.g., mating member/recess, magnetic arrangement) may be provided on at least one of the side walls  116  and the side surface of the pod assembly. 
     For example, the attachment structure may include a mating member that is formed on the side wall  116  (of the first frame  110  and/or second frame  112 ) and a corresponding recess that is formed on the side surface of the pod assembly. Conversely, the mating member may be formed on the side surface of the pod assembly, while the corresponding recess may be formed on the side wall  116  (of the first frame  110  and/or second frame  112 ). In a non-limiting embodiment, the mating member may be a rounded structure to facilitate the engagement/disengagement of the attachment structure, while the recess may be a concave indentation that corresponds to the curvature of the rounded structure. The mating member may also be spring-loaded so as to retract (via spring compression) when the pod assembly is being inserted into the through-hole  114  and protract (via spring decompression) when mating member becomes aligned with the corresponding recess. The engagement of the mating member with the corresponding recess may result in an audible click, which notifies the adult vaper that the pod assembly is secured and properly positioned within the through-hole  114  of the dispensing body  104 . 
     In another example, the attachment structure may include a magnetic arrangement. For instance, a first magnet may be arranged in the side wall  116  (of the first frame  110  and/or second frame  112 ), and a second magnet may be arranged in the side surface of the pod assembly. The first and/or second magnets may be exposed or hidden from view behind a layer of material. The first and second magnets are oriented so as to be attracted to each other, and a plurality of pairs of the first and second magnets may be provided to ensure that the pod assembly will be secure and properly aligned within the through-hole  114  of the dispensing body  104 . As a result, when the pod assembly is inserted in the through-hole  114 , the pair(s) of magnets (e.g., first and second magnets) will be attracted to each other and, thus, hold the pod assembly within the through-hole  114  while properly aligning the channel outlet of the pod assembly with the vapor passage  106  of the dispensing body  104 . 
       FIG. 6  is a perspective view of the body portion of  FIG. 2 . Referring to  FIG. 6 , the body portion  118  may be a tube-like structure that constitutes a substantial segment of the dispensing body  104 . The cross-section of the body portion  118  may be oval-shaped, although other shapes are possible depending on the structure of the frame portion. An adult vaper may hold the e-vapor apparatus by the body portion  118 . Accordingly, the body portion  118  may be formed of (or covered with) a material that provides enhanced gripping and/or texture appeal to the fingers 
       FIG. 7  is a perspective view of the end piece of  FIG. 2 . Referring to  FIG. 7 , the end piece  120  is configured to be inserted in the distal end of the body portion  118 . The shape of the end piece  120  may correspond to the shape of the distal end of the body portion  118  so as to provide a relatively smooth and continuous transition between the two surfaces. 
       FIG. 8  is a perspective view of another dispensing body of an e-vapor apparatus according to an example embodiment. Referring to  FIG. 8 , the dispensing body  204  includes a side wall  216  defining a through-hole  214  that is configured to receive a pod assembly. A substantial portion of the framework of the dispensing body  204  is provided by the first frame  210 , the frame trim  211 , and the second frame  212  (e.g.,  FIG. 9 ). A vapor passage  206  and a first mouthpiece  208  are provided at a proximal portion of the dispensing body  204 . 
       FIG. 9  is an exploded view of the dispensing body of  FIG. 8 . Referring to  FIG. 9 , the frame trim  211  is sandwiched between the first frame  210  and the second frame  212 . However, it should be understood that it is possible to modify and structure the first frame  210  and the second frame  212  such that the frame trim  211  is not needed. The vapor passage  206  may be defined by both the proximal ends of the first frame  210  and the second frame  212  as well as the second mouthpiece  209 . As a result, the vapor passage  206  extends from the side wall  216  to the outlet end of the second mouthpiece  209 . The first mouthpiece  208  is configured to slip onto the second mouthpiece  209 . In an example embodiment, the first mouthpiece  208  may be structured to be removable, while the second mouthpiece  209  may be structured to be permanent. Alternatively, the first mouthpiece  208  may be integrated with the second mouthpiece  209  to form a single structure that is removable. 
     A first button  222 , a second button  224 , and a third button  226  may be provided on the second frame  212  of the dispensing body  204 . In an example embodiment, the first button  222  may be a display (e.g., battery level indicator), the second button  224  may control an amount of vapor precursor available to the heater, and the third button  226  may be the power button. However, it should be understood that example embodiments are not limited thereto. Notably, the buttons can have different implementations depending on the desired functionalities. Accordingly, a different number of buttons (and/or of different shapes) may be provided in the same proximity or at a different location on the e-vapor apparatus. Furthermore, the features and considerations in connection with the dispensing body  104  that are also applicable to the dispensing body  204  may be as discussed supra in connection with the dispensing body  104 . 
       FIG. 10  is a perspective view of the first mouthpiece of  FIG. 9 . Referring to  FIG. 10 , the first mouthpiece  208  is configured to fit over the second mouthpiece  209 . Thus, the inner surface of the first mouthpiece  208  may correspond to an outer surface of the second mouthpiece  209 . 
       FIG. 11  is a perspective view of the second mouthpiece of  FIG. 9 . 
     Referring to  FIG. 11 , the second mouthpiece  209  defines a vapor passage  206  therein. The second mouthpiece  209  may resemble the combined proximal ends of the first frame  110  and the second frame  112  that define the vapor passage  106  of the dispensing body  104 . 
       FIG. 12  is a perspective view of the first frame of  FIG. 9 . Referring to  FIG. 12 , the first frame  210  includes a side wall  216  that defines a through-hole  214 . The top end of the first frame  210  may include a connection structure that facilitates the connection of at least the second mouthpiece  209  thereto. 
       FIG. 13  is a perspective view of the frame trim of  FIG. 9 . Referring to  FIG. 13 , the frame trim  211  may be in the form of a curved strip that is supported by a central plate. When arranged between the first frame  210  and the second frame  212 , the frame trim  211  forms a side surface of the dispensing body  204 , although example embodiments are not limited thereto. 
       FIG. 14  is a perspective view of the second frame of  FIG. 9 . Referring to  FIG. 14 , the second frame  212  includes a side wall  216  that defines a through-hole  214 . The top end of the second frame  212  may include a connection structure that facilitates the connection of at least the second mouthpiece  209  thereto. In addition, the surface of the second frame  212  may be provided with a pattern or textured appearance. Such patterning and texturing may be aesthetic (e.g., visually appealing) and/or functional (e.g., enhanced grip) in nature. Although not shown, the surface of the first frame  210  may be similarly provided. 
       FIG. 15  is a perspective view of a pod assembly of an e-vapor apparatus according to an example embodiment. Referring to  FIG. 15 , the pod assembly  302  includes a pod trim  310  that is arranged between a first cap  304  and a second cap  314 . The first cap  304  may be regarded as a front cap, and the second cap  314  may be regarded as a rear cap (or vice versa). The first cap  304  and the second cap  314  may be formed of a transparent material to permit a viewing of the contents (e.g., vapor precursor) in the pod assembly  302 . The pod trim  310  defines a channel outlet  312  for the release of vapor generated within the pod assembly  302 . 
     The pod assembly  302  is a self-contained article that can be sealed with a protective film that wraps around the pod trim  310 . Additionally, because of the closed system nature of the pod assembly  302 , the risk of tampering and contamination can be reduced. Also, the chance of unwanted physical exposure to the vapor precursor within the pod assembly  302  (e.g., via a leak) can be reduced. Furthermore, the pod assembly  302  can be structured so as to prevent refilling. 
       FIG. 16  is a top view of the pod assembly of  FIG. 15 . Referring to  FIG. 16 , the second cap  314  is wider than the first cap  304 . As a result, the pod trim  310  may slant outwards from the first cap  304  to the second cap  314 . However, it should be understood that other configurations are possible depending on the design of the pod assembly  302 . 
       FIG. 17  is a side view of the pod assembly of  FIG. 15 . Referring to  FIG. 17 , the second cap  314  is longer than the first cap  304 . As a result, the pod trim  310  may slant outwards from the first cap  304  to the second cap  314 . As a result, the pod assembly  302  may be inserted in a dispensing body such that the side corresponding to the first cap  304  is received in the through-hole first. In an example embodiment, the pod assembly  302  may be inserted in the through-hole  114  of the dispensing body  104  and/or the through-hole  214  of the dispensing body  204 . 
       FIG. 18  is an exploded view of the pod assembly of  FIG. 15 . Referring to  FIG. 18 , the internal space of the pod assembly  302  may be divided into a plurality of compartments by virtue of the components therein. For instance, the tapered outlet of the vapor channel  308  may be aligned with the channel outlet  312 , and the space bounded by the first cap  304 , the vapor channel  308 , the pod trim  310 , and the second cap  314  may be regarded as the vapor precursor compartment. Additionally, the bounded space under the vapor channel  308  may be regarded as the device compartment. For instance, the device compartment may include the vaporizer  306 . One benefit of including the vaporizer  306  in the pod assembly  302  is that the vaporizer  306  will only be used for the amount of vapor precursor contained within the vapor precursor compartment and, thus, will not be overused. 
       FIG. 19  a perspective view of several pod assemblies according to an example embodiment. Referring to  FIG. 19 , each of the pod assemblies  402  includes a pod trim  410  arranged between a first cap  404  and a second cap  414 . The vapor channel  408  is aligned with the channel outlet  412  and arranged above the vaporizer  406 . The pod assembly  402  is sealed to hold a vapor precursor  418  therein and to preclude tampering therewith. The vapor precursor compartment of the pod assembly  402  is configured to hold the vapor precursor  418 , and the device compartment includes the vaporizer  406 . 
     In further detail, the pod assembly  402  for an e-vapor apparatus may include a vapor precursor compartment configured to hold a vapor precursor  418  therein. A device compartment is in fluidic communication with the vapor precursor compartment. The device compartment includes a vaporizer  406 . A vapor channel  408  extends from the device compartment and traverses the vapor precursor compartment. 
     The pod assembly  402  is configured for insertion into a dispensing body. As a result, the dimensions of the pod assembly  402  may correspond to the dimensions of the through-hole (e.g.,  114 ) of the dispensing body (e.g.,  104 ). The vapor channel  408  may be between the mouthpiece (e.g.,  108 ) and the device compartment when the pod assembly  402  is inserted into the through-hole of the dispensing body. 
     An attachment structure (e.g., male/female member arrangement, magnetic arrangement) may be provided on at least one of the side wall (e.g.,  116 ) of the through-hole (e.g.,  114 ) and a side surface of the pod assembly  402 . The attachment structure may be configured to engage and hold the pod assembly  402  upon insertion into the through-hole of the dispensing body. In addition, the channel outlet  412  may be utilized to secure the pod assembly  402  within the through-hole of the dispensing body. For instance, the dispensing body may be provided with a retractable vapor connector that is configured to insert into the channel outlet  412  so as to secure the pod assembly  402  while also supplementing the vapor path from the channel outlet  412  to the vapor passage (e.g.,  106 ) of the dispensing body (e.g.,  104 ). The vapor connector may also be a rounded structure and/or spring-loaded to facilitate its retraction (e.g., via spring compression) and protraction (e.g., via spring decompression). 
     In an example embodiment, the vapor precursor compartment of the pod assembly  402  may surround the vapor channel  408 . For instance, the vapor channel  408  may pass through a center of the vapor precursor compartment, although example embodiments are not limited thereto. 
     Alternatively, instead of the vapor channel  408  shown in  FIG. 19 , a vapor channel may be in a form of a pathway that is arranged along at least one sidewall of the precursor compartment. For example, a vapor channel may be provided in a form of a pathway that spans between the first cap  404  and the second cap  414  while extending along one or both sides of an inner surface of the pod trim  410 . As a result, the pathway may have a thin, rectangular cross-section, although example embodiments are not limited thereto. When the pathway is arranged along two sidewalls of the vapor precursor compartment (e.g., both inner sidewalls of the pod trim  410 ), the pathway along each sidewall may be configured to converge at a position (e.g., channel outlet  412 ) that is aligned with the vapor passage (e.g.,  106 ) of the dispensing body (e.g.,  104 ) when the pod assembly  402  is received in the through-hole  114 . 
     In another instance, the vapor channel may be in a form of a conduit that is arranged in at least one corner of the vapor precursor compartment. Such a corner may be at the interface of the first cap  404  and/or the second cap  414  with the inner surface of the pod trim  410 . As a result, the conduit may have a triangular cross-section, although example embodiments are not limited thereto. When the conduit is arranged in at least two corners (e.g., front corners, rear corners, diagonal corners, side corners) of the vapor precursor compartment, the conduit in each corner may be configured to converge at a position (e.g., channel outlet  412 ) that is aligned with the vapor passage (e.g.,  106 ) of the dispensing body (e.g.,  104 ) when the pod assembly  402  is received in the through-hole  114 . 
     The vapor precursor compartment and the device compartment may be at opposite ends of the pod assembly  402 . The device compartment may include a memory device. The memory device may be coded with an electronic identity to permit at least one of an authentication of the pod assembly  402  and a pairing of operating parameters specific to a type of the pod assembly  402  when the pod assembly  402  is inserted into the through-hole of the dispensing body (e.g., smart calibration). The electronic identity may help prevent counterfeiting. The operating parameters may help optimize a vaping experience without placing a burden on the adult vaper to determine the proper settings. In an example embodiment, the level of vapor precursor in the pod assembly  402  may be tracked. Additionally, the activation of the pod assembly  402  may be restricted once its intended usage life has been exceeded. Thus, the pod assembly  402  (and  302 ) may be regarded as a smart pod. 
     A side surface of the pod assembly  402  includes at least one electrical contact  416  and/or data connection  417  (e.g., two or three electrical contacts and/or data connections). The dispensing body may be configured to perform at least one of supply power to and communicate with the pod assembly  402  via the at least one electrical contact  416 . The at least one electrical contact  416  may be provided at an end of the pod assembly  402  corresponding to the device compartment. Because of its smart capability, the pod assembly  402  may communicate with dispensing body and/or another electronic device (e.g., smart phone). As a result, usage patterns and other information (e.g., flavor intensity, throat feel, puff count) may be generated, stored, transferred, and/or displayed. The smart capability, connecting features, and other related aspects of the pod assembly, dispensing body, and overall e-vapor apparatus are additionally discussed in U.S. Application No. 62/151,160 (Atty. Dkt. No. 24000-000200-US-PS1 (ALCS2853)), U.S. Application No. 62/151,179 (Atty. Dkt. No. 24000-000201-US-PS1 (ALCS2854)), and U.S. Application No. 62/151,248 (Atty. Dkt. No. 24000-000202-US-PS1 (ALCS2855)), the entire contents of each of which are incorporated herein by reference. 
       FIG. 20  is a view of an e-vapor apparatus with a pod assembly inserted in a dispensing body according to an example embodiment. Referring to  FIG. 20 , an e-vapor apparatus  500  includes a pod assembly  502  (e.g., smart pod) that is inserted within a dispensing body  504 . The pod assembly  502  may be as previously described in connection with the pod assembly  302  and the pod assembly  402 . As a result, the pod assembly  502  may be a hassle-free and leak-free component that can be replaced with relative ease when the vapor precursor therein runs low/out or when another flavor is desired. 
       FIG. 21  illustrates a device system of a dispensing body according to an example embodiment. A device system  2100  may be the system within the dispensing body  104  and the dispensing body  204 . 
     The device system  2100  includes a controller  2105 , a power supply  2110 , actuator controls  2115 , a pod electrical/data interface  2120 , device sensors  2125 , input/output (I/O) interfaces  2130 , vaper indicators  2135 , at least one antenna  2140  and a storage medium  2145 . The device system  2100  is not limited to the features shown in  FIG. 21 . For example, the device system  2100  may include additional components. However, for the sake of brevity, the additional components are not described. 
     The controller  2105  may be hardware, firmware, hardware executing software or any combination thereof. When the controller  2105  is hardware, such existing hardware may include one or more Central Processing Units (CPUs), digital signal processors (DSPs), application-specific-integrated-circuits (ASICs), field programmable gate arrays (FPGAs) computers or the like configured as special purpose machines to perform the functions of the processor  220 . As stated above, CPUs, DSPs, ASICs and FPGAs may generally be referred to as processing devices. 
     In the event where the controller  2105  is a processor executing software, the controller  2105  is configured as a special purpose machine to execute the software, stored in the storage medium  2145 , to perform the functions of the at least one of the controller  2105 . 
     As disclosed herein, the term “storage medium”, “computer readable storage medium” or “non-transitory computer readable storage medium” may represent one or more devices for storing data, including read only memory (ROM), random access memory (RAM), magnetic RAM, core memory, magnetic disk storage mediums, optical storage mediums, flash memory devices and/or other tangible machine readable mediums for storing information. The term “computer-readable medium” may include, but is not limited to, portable or fixed storage devices, optical storage devices, and various other mediums capable of storing, containing or carrying instruction(s) and/or data. 
     Referring to  FIG. 21 , the controller  2105  communicates with the power supply  2110 , the actuator control  2115 , the pod electrical/data interface  2120 , the device sensors  2125 , the input/output (I/O) interfaces  2130 , the vaper indicators  2135 , the at least one antenna  2140 . 
     The controller  2105  communicates with the CC-NVM in the pod through the pod electrical/data interface  2120 . More specifically, the controller  2105  may utilize encryption to authenticate the pod. As will be described, the controller  2105  communicates with the CC-NVM package to authenticate the pod. More specifically, the non-volatile memory is encoded during manufacture with product and other information for authentication. 
     The memory device may be coded with an electronic identity to permit at least one of an authentication of the pod and a pairing of operating parameters specific to a type of the pod when the pod assembly  402  is inserted into the through-hole of the dispensing body. In addition to authenticating based on an electronic identity of the pod, the controller  2105  may authorize use of the pod based on an expiration date of the stored vapor precursor and/or heater encoded into the non-volatile memory of the CC-NVM. If the controller determines that the expiration date encoded into the non-volatile memory has passed, the controller may not authorize use of the pod and disable the e-vaping device. 
     The controller  2105  (or storage medium  2145 ) stores key material and proprietary algorithm software for the encryption. For example, encryption algorithms rely on the use of random numbers. The security of these algorithms depends on how truly random these numbers are. These numbers are usually pre-generated and coded into the processor or memory devices. Example embodiments may increase the randomness of the numbers used for the encryption by using the puffing parameters e.g. puff durations, intervals between puffs, or combinations of them, to generate numbers that are more random and more varying from individual to individual than pre-generated random numbers. All communications between the controller  2105  and the pod may be encrypted. 
     Moreover, the pod can be used to as a general pay-load carrier for other information such as software patches for the e-vaping device. Since encryption is used in all the communications between the pod and the controller  2105 , such information is more secure and the e-vaping device is less prone to being installed with malwares or viruses. Use of the CC-NVM as an information carrier such as data and software updates allows the e-vaping device to be updated with software without it being connected to the Internet and for the adult vaper to go through a downloading process as with most other consumer electronics devices requiring periodic software updates. 
     The controller  2105  may also include a cryptographic accelerator to allow resources of the controller  2105  to perform functions other than the encoding and decoding involved with the authentication. The controller  2105  may also include other security features such as preventing unauthorized use of communication channels and preventing unauthorized access to data if a pod or vaper is not authenticated. 
     In addition to a cryptographic accelerator, the controller  2105  may include other hardware accelerators. For example, the controller  2105  may include a floating point unit (FPU), a separate DSP core, digital filters and Fast Fourier Transform (FFT) modules. 
     The controller  2105  operates a real time operating system (RTOS), controls the device system  2100  and may be updated through communicating with the CC-NVM or when the device system  2100  is connected with other devices (e.g., a smart phone) through the I/O interfaces  2130  and/or the antenna  2140 . The I/O interfaces  2130  and the antenna  2140  allow the device system  2100  to connect to various external devices such as smart phones, tablets, and PCs. For example, the I/O interfaces  2130  may include a micro-USB connector. The micro-USB connector may be used by the device system  2100  to charge the power source  2110   b.    
     The controller  2105  may include on-board RAM and flash memory to store and execute code including analytics, diagnostics and software upgrades. As an alternative, the storage medium  2145  may store the code. Additionally, in another example embodiment, the storage medium  2145  may be on-board the controller  2105 . 
     The controller  2105  may further include on-board clock, reset and power management modules to reduce an area covered by a PCB in the dispensing body. 
     The device sensors  2125  may include a number of sensor transducers that provide measurement information to the controller  2105 . The device sensors  2125  may include a power supply temperature sensor, an external pod temperature sensor, a current sensor for the heater, power supply current sensor, air flow sensor and an accelerometer to monitor movement and orientation. The power supply temperature sensor and external pod temperature sensor may be a thermistor or thermocouple and the current sensor for the heater and power supply current sensor may be a resistive based sensor or another type of sensor configured to measure current. The air flow sensor may be a microelectromechanical system (MEMS) flow sensor or another type of sensor configured to measure air flow. 
     The data generated from the number of sensor transducers may be sampled at a sample rate appropriate to the parameter being measured using a discrete, multi-channel analog-to-digital converter (ADC). 
     The controller  2105  may adapt heater profiles for a vapor precursor and other profiles based on the measurement information received from the controller  2105 . For the sake of convenience, these are generally referred to as vaping or vapor profiles. 
     The heater profile identifies the power profile to be supplied to the heater during the few seconds when puffing takes place. For example of a heater profile can be: deliver maximum power to the heater when a puff is initiated, but then after a second or so immediately reduce the power to half way or a quarter way or so. 
     The modulation of electrical power is usually implemented using pulse wave modulation—instead of flipping an on/off switch where the power is either full on or off. 
     In addition, a heater profile can also be modified by the extent to which the adult vaper applies negative pressure to the e-vaping device. The use of the MEMS flow sensor allows puff strength to be measured and used as feedback to the controller  2105  to adjust the power delivered to the heater of the pod, which may be referred to as heating or energy delivery. 
     When the controller  2105  recognizes the pod currently installed (e.g., via SKU), the controller  2105  matches an associated heating profile that is designed for that particular pod. The controller  2105  and the storage medium  2145  will store data and algorithms that allow the generation of heating profiles for all SKUs. The adult vapers may also adjust heating profiles to suit their preferences. 
     As shown in  FIG. 21 , the controller  2105  sends data to and receives data from the power supply  2110 . The power supply  2110  includes a power source  2110   b  and a power controller  2110   a  to manage the power output by the power source  2110   b.    
     The power source  2110   b  may be a Lithium-ion battery or one of its variants, for example a Lithium-ion polymer battery. Alternatively, the power source  2110   b  may be a Nickel-metal hydride battery, a Nickel cadmium battery, a Lithium-manganese battery, a Lithium-cobalt battery or a fuel cell. Alternatively, the power source  2110   b  may be rechargeable and include circuitry allowing the battery to be chargeable by an external charging device. In that case, the circuitry, when charged, provides power for a desired (or alternatively a pre-determined) number of puffs, after which the circuitry must be re-connected to an external charging device. 
     The power controller  2110   a  provides commands to the power source  2110   b  based on instructions from the controller  2105 . For example, the power supply  2110  may receive a command from the controller  2105  to provide power to the pod (through the electrical/data interface  2120 ) when the pod is authenticated and the adult vaper activates the device system  2100  (e.g., by activating a switch such as a toggle button, capacitive sensor, IR sensor). When the pod is not authenticated, the controller  2105  may either send no command to the power supply  2110  or send an instruction to the power supply  2110  to not provide power. In another example embodiment, the controller  2105  may disable all operations of the device system  2100  if the pod is not authenticated. 
     In addition to supplying power to the pod, the power supply  2110  also supplies power to the controller  2105 . Moreover, the power controller  2110   a  may provide feedback to the controller  2105  indicating performance of the power source  2110   b.    
     The controller  2105  sends data to and receives data from the at least one antenna  2140 . The at least one antenna  2140  may include a Near Field Communication (NFC) modem and a Bluetooth Low Energy (LE) modem and/or other modems for other wireless technologies (e.g., Wi-Fi). In an example embodiment, the communications stacks are in the modems, but the modems are controlled by the controller  2105 . The Bluetooth LE modem is used for data and control communications with an application on an external device (e.g., smart phone). The NFC modem may be used for pairing of the e-vaping device to the application and retrieval of diagnostic information. Moreover, the NFC modem may be used to provide location information (for an adult vaper to find the e-vaping device) or authentication during a purchase. 
     As described above, the device system  2100  may generate and adjust various profiles for vaping. The controller  2105  uses the power supply  2110  and the actuator controls  2115  to regulate the profile for the adult vaper. 
     The actuator controls  2115  include passive and active actuators to regulate a desired vapor profile. For example, the dispensing body may include an inlet channel within a mouthpiece. The actuator controls  2115  may control the inlet channel based on commands from the controller  2105  associated with the desired vapor profile. 
     Moreover, the actuator controls  2115  are used to energize the heater in conjunction with the power supply  2110 . More specifically, the actuator controls  2115  are configured to generate a drive waveform associated with the desired vaping profile. As described above, each possible profile is associated with a drive waveform. Upon receiving a command from the controller  2105  indicating the desired vaping profile, the actuator controls  2115  may produce the associated modulating waveform for the power supply  2110 . 
     The controller  2105  supplies information to the vaper indicators  2135  to indicate statuses and occurring operations to the adult vaper. The vaper indicators  2135  include a power indicator (e.g., LED) that may be activated when the controller  2105  senses a button press by the adult vaper. The vaper indicators  2135  may also include a vibrator, speaker, an indicator for current state of a vaper-controlled vaping parameter (e.g., vapor volume) and other feedback mechanisms. 
     Furthermore, the device system  2100  may include a number of on-product controls  2150  that provide commands from an adult vaper to the controller  2105 . The on-product controls  2150  include an on-off button which may be a toggle button, capacitive sensor or IR sensor, for example. The on-product controls  2150  may further include a vaping control button (if the adult vaper desires to override the buttonless vaping feature to energize the heater), a hard reset button, a touch based slider control (for controlling setting of a vaping parameter such as puff volume), a vaping control button to activate the slider control and a mechanical adjustment for an air inlet. 
     Once a pod is authenticated, the controller  2105  operates the power supply  2110 , the actuator controls  2115 , vaper indicators  2135  and antenna  2140  in accordance with an adult vaper using the e-vaping device and the information stored by the CC-NVM on the pod. Moreover, the controller  2105  may include logging functions and be able to implement algorithms to calibrate the e-vaping device. The logging functions are executed by the controller  2105  to record usage data as well any unexpected events or faults. The recorded usage data may be used for diagnostics and analytics. The controller  2105  may calibrate the e-vaping device using buttonless vaping, a vaper configuration and the stored information on the CC-NVM including puff sensing, vapor precursor level, and vapor precursor composition. For example, the controller  2105  may command the power supply  2110  to supply power to the heater in the pod based on a vaping profile associated with the vapor precursor composition in the pod. Alternatively, a vaping profile may be encoded in the CC-NVM and utilized by the controller  2105 . 
       FIG. 22  illustrates a pod system diagram of a dispensing body according to an example embodiment. A pod system  2200  may be within the pod assembly  502 , the pod assembly  302  and the pod assembly  402 . 
     As shown in  FIG. 22 , the pod system  2200  includes a CC-NVM  2205 , a body electrical/data interface  2210 , a heater  2215  and pod sensors  2220 . The pod system  2200  communicates with the device system  2100  through the body electrical/data interface  2210  and the pod electrical/data interface  2120 . The body electrical/data interface  2210  may correspond to the battery contacts  416  and data connection  417  connected within the pod assembly  402 , shown in  FIG. 19 , for example. Thus, the CC-NVM  2205  is coupled to the data connection  417  and the battery contacts  416 . 
     The CC-NVM  2205  includes a cryptographic coprocessor  2205   a  and a non-volatile memory  2205   b . The controller  2105  may access the information stored on the non-volatile memory  2205   b  for the purposes of authentication and operating the pod by communicating with the cryptographic coprocessor  2205   a.    
     The non-volatile memory  2205   b  may be coded with an electronic identity to permit at least one of an authentication of the pod and a pairing of operating parameters specific to a type of the pod when the pod assembly is inserted into the through-hole of the dispensing body. In addition to authenticating based on an electronic identity of the pod, the controller  2105  may authorize use of the pod based on an expiration date of the stored vapor precursor and/or heater encoded into the non-volatile memory  2205   b  of the CC-NVM. If the controller determines that the expiration date encoded into the non-volatile memory  2205   b  has passed, the controller may not authorize use of the pod and disable the e-vaping device. 
     Moreover, the non-volatile memory  2205   b  may store information such as a stock keeping unit (SKU) of the vapor precursor in the vapor precursor compartment (including vapor precursor composition), software patches for the device system  2100 , product usage information such as puff count, puff duration, and vapor precursor level. The non-volatile memory  2205   b  may store operating parameters specific to the type of the pod and the vapor precursor composition. For example, the non-volatile memory  2205   b  may store the electrical and mechanical design of the pod for use by the controller  2105  to determine commands corresponding to a desired vaping profile. 
     The vapor precursor level in the pod may be determined in one of two ways, for example. In one example embodiment, one of the pod sensors  2220  directly measures the vapor precursor level in the pod. 
     In another example embodiment, the non-volatile memory  2205   b  stores the number of puffs taken from the pod and the controller  2105  uses the number of puffs taken as a proxy to the amount of vapor precursor that is vaporized. 
     The controller  2105  and/or the storage medium  2145  may store vapor precursor calibration data that identifies an operating point for the vapor precursor composition. The vapor precursor calibration data include data describing how flow rate changes with a remaining vapor precursor level or how volatility changes with an age of the vapor precursor and may be used for calibration by the controller  2105 . The vapor precursor calibration data may be stored by the controller  2105  and/or the storage medium  2145  in a table format. The vapor precursor calibration data allows the controller  2105  to equate the number of puffs taken to the amount of vapor precursor that is vaporized. 
     The controller  2105  writes the vapor precursor level and number of puffs taken back to the non-volatile memory  2205   b  in the pod so if the pod is removed from the dispensing body and later on re-installed, an accurate vapor precursor level of the pod will still be known by the controller  2105 . 
     The operating parameters (e.g., power supply, power duration, air channel control) are referred to as a vaping profile. Moreover, the non-volatile memory  2205   b  may record information communicated by the controller  2105 . The non-volatile memory  2205   b  may retain the recorded information even when the dispensing body becomes disconnected from the pod. 
     In an example embodiment, the non-volatile memory  2205   b  may be a programmable read only memory. 
     The heater  2215  is actuated by the controller  2105  and transfers heat to the vapor precursor in accordance with the commanded profile (volume, temperature (based on power profile) and flavor) from the controller  2105 . 
     The heater  2215  may be a wire coil surrounding a wick, a mesh, a surface or made out of a ceramic material for example. Examples of suitable electrically resistive materials include titanium, zirconium, tantalum and metals from the platinum group. Examples of suitable metal alloys include stainless steel, nickel-, cobalt-, chromium-, aluminum-titanium-zirconium-, hafnium-, niobium-, molybdenum-, tantalum-, tungsten-, tin-, gallium-, manganese- and iron-containing alloys, and super-alloys based on nickel, iron, cobalt, stainless steel. For example, the heater may be formed of nickel aluminides, a material with a layer of alumina on the surface, iron aluminides and other composite materials, the electrically resistive material may optionally be embedded in, encapsulated or coated with an insulating material or vice-versa, depending on the kinetics of energy transfer and the external physicochemical properties required. In one embodiment, the heater comprises at least one material selected from the group consisting of stainless steel, copper, copper alloys, nickel-chromium alloys, superalloys and combinations thereof. In an embodiment, the heater  2215  is formed of nickel-chromium alloys or iron-chromium alloys. In one embodiment, the heater  2215  can be a ceramic heater having an electrically resistive layer on an outside surface thereof. 
     In another embodiment, the heater  2215  may be constructed of an iron-aluminide (e.g., FeAl or Fe 3 Al), such as those described in commonly owned U.S. Pat. No. 5,595,706 to Sikka et al. filed Dec. 29, 1994, or nickel aluminides (e.g., Ni 3 Al), the entire contents of which are hereby incorporate by reference. 
     The heater  2215  may determine an amount of vapor precursor to heat based on feedback from the pod sensors or the controller  2105 . The flow of vapor precursor may be regulated by a micro-capillary or wicking action. Moreover, the controller  2105  may send commands to the heater  2215  to adjust an air inlet to the heater  2215 . 
     The pod sensor  2220  may include a heater temperature sensor, vapor precursor flow rate monitor and air flow monitor. The heater temperature sensor may be a thermistor or thermocouple and the flow rate sensing may be performed by the pod system  2200  using electrostatic interference or an in-liquid rotator. The air flow sensor may be a microelectromechanical system (MEMS) flow sensor or another type of sensor configured to measure air flow. 
     The data generated from the pod sensors  2220  may be sampled at a sample rate appropriate to the parameter being measured using a discrete, multi-channel analog-to-digital converter (ADC). 
     While a number of example embodiments have been disclosed herein, it should be understood that other variations may be possible. Such variations are not to be regarded as a departure from the spirit and scope of the present disclosure, and all such modifications as would be obvious to one skilled in the art are intended to be included within the scope of the following claims.
