Abstract

A pod having a conductive base allows for electrodes on a vaping device to be connected, so that a locked out component in the vaping device is connected through a loop-back connection using the conductive base. To accommodate vaping device that make use of an additional bypass detection electrode, the conductive base may have a non-conductive patch created through the application of a coating or film, or through an aperture in the base. A complementary device allows for the delivery of power to a pod when its lockout electrodes are connected by an inserted pod, while a bypass electrode is not electrically connected by the pod to the lockout electrodes.

Description

File#: OMNA 026 Vaporizer Pod with Conductive Base Cross Reference to Related Applications [0001] This is the first application for the instant invention.
Technical Field
[0002] This application relates generally to a pod for use in conjunction with a vaporizer device, and more particularly to a pod having a conductive base, which may be provided through the use of a metal sheathed end cap or a metallic end cap, for use in a vaporizer device having an electrical lockout for a device subsystem.
Background
[0003] Electronic cigarettes and vaporizers are well regarded tools in smoking cessation.
In some instances, these devices are also referred to as an electronic nicotine delivery system (ENDS). A nicotine based liquid solution, commonly referred to as e-liquid, often paired with a flavoring, is atomized in the ENDS for inhalation by a user. In some embodiments, e-liquid is stored in a cartridge or pod, which is a removable assembly having a reservoir from which the e-liquid is drawn towards a heating element by capillary action through a wick. In many such ENDS, the pod is removable, disposable, and is sold pre-filled.
[0004] In some ENDS, a refillable tank is provided, and a user can purchase a vaporizable solution with which to fill the tank. This refillable tank is often not removable, and is not intended for replacement. A fillable tank allows the user to control the fill level as desired. Disposable pods are typically designed to can-y a fixed amount of vaporizable liquid, and are intended for disposal after consumption of the e-liquid. The ENDS cartridges, unlike the aforementioned tanks, are not typically designed to be refilled. Each cartridge stores a predefined quantity of e-liquid, often in the range of 0.5 to 3m1. In ENDS systems, the e-liquid is typically composed of a combination of any of vegetable glycerine, propylene glycol, nicotine and flavorings. In systems designed for the delivery of other compounds, different compositions may be used. In some examples, an atomizable liquid may be based on propylene glycol as a major component, may use terpenes in place of other flavoring compounds and may be used to deliver cannabinoids such as tetrahydrocannabinol (THC) and cannabidiol (CBD).

Date Recue/Date Received 2022-09-23 File#: OMNA 026
[0005] In the manufacturing of the disposable cartridge, different techniques are used for different cartridge designs. Typically, the cartridge has a wick that allows e-liquid to be drawn from the e-liquid reservoir to an atomization chamber. In the atomization chamber, a heating element in communication with the wick is heated to encourage aerosolization of the e-liquid. The aerosolized e-liquid can be drawn through a defined air flow passage towards a user's mouth.
[0006] Figures 1A, 1B and 1C provide front, side and bottom views of an exemplary pod 50. Pod 50 is composed of a reservoir 52 having an air flow passage 54, and an end cap assembly 56 that is used to seal an open end of the reservoir 52. End cap assembly has wick feed lines 58 which allow e-liquid stored in reservoir 52 to be provided to a wick (not shown in Figure 1). To ensure that e-liquid stored in reservoir 52 stays in the reservoir and does not seep or leak out, and to ensure that end cap assembly 56 remains in place after assembly, seals 60 can be used to ensure a more secure seating of the end cap assembly 56 in the reservoir 52. In the illustrated embodiment, seals 60 may be implemented through the use of o-rings.
[0007] As noted above, pod 50 includes a wick that is heated to atomize the e-liquid. To provide power to the wick heater, electrical contacts 62 are placed at the bottom of the pod 50. In the illustrated embodiment, the electrical contacts 62 are illustrated as circular.
The particular shape of the electrical contacts 62 should be understood to not necessarily germane to the function of the pod 50.
[0008] Because an ENDS device is intended to allow a user to draw or inhale as part of the nicotine delivery path, an air inlet 64 is provided on the bottom of pod 50. Air inlet 64 allows air to flow into a pre-wick air path through end cap assembly 56. The air flow path extends through an atomization chamber and then through post wick air flow passage 54.
[0009] Figure 2 illustrates a cross section taken along line A in Figure 1B.
This cross section of the pod is shown with a complete (non-sectioned) wick 72 and heater 74. End cap assembly 56 resiliently mounts to an end of air flow passage 54 in a manner that allows air inlet 64 to form a complete air path through pod 50. This connection allows airflow from air inlet 64 to connect to the post air flow path through passage 54 through atomization chamber 70. Within atomization chamber 70 is both wick 72 and heater 74.
When power is applied to contacts 62, the temperature of the heater increases and allows for the volatilization of e-liquid that is drawn across wick 72.

Date Recue/Date Received 2022-09-23 File#: OMNA 026
[0010] Typically the heater 74 reaches temperatures well in excess of the vaporization temperature of the e-liquid. This allows for the rapid creation of a vapor bubble next to the heater 74. As power continues to be applied the vapor bubble increases in size, and reduces the thickness of the bubble wall. At the point at which the vapor pressure exceeds the surface tension the bubble will burst and release a mix of the vapor and the e-liquid that formed the wall of the bubble. The e-liquid is released in the form of aerosolized particles and droplets of varying sizes. These particles are drawn into the air flow and into post wick air flow passage 54 and towards the user.
[0011] In other embodiments of pod 50, variations in the design shown in Figures 1 and 2 are employed in attempts to reduce known issues in assembly and possibly leakage.
Figure 3 illustrates one such pod 50, shown in an inverted orientation with respect to the pod 50 of Figure 1. Figure 3 provides a cross section of pod 50 to allow for discussion of the internal components. As before, a reservoir 52, having a post-wick airflow passage, is employed to store e-liquid. The reservoir 52 is shown without a mouthpiece, but has an open end opposed to the end at which a mouthpiece would be affixed. This open end is sealed, typically after filling with e-liquid, through the insertion of end cap 56. End cap 56 has a pair of wick feed lines 58 that allow e-liquid from the reservoir to enter end cap 56 so that it can be absorbed by wick 72. E-liquid is drawn across wick 72 by capillary forces, and is brought towards heater 74. Heater 74 resides within atomization chamber 70, which is positioned as a part of an airflow passage within pod 50. The airflow passage begins with the inlet 64, passes through atomization chamber 70 and proceeds into the post wick airflow passage 54. Heater 74 is connected to electrical contacts 62 which are used as an interface with the vaping device. Power is applied across contacts 62 to energize heater 74. This results in the volatilization of the e-liquid drawn across the wick 72. As the e-liquid is atomized, it is entrained within an airflow through the airflow passage of pod 50. Where the pod of Figures 1 and 2 makes use of 0-rings to seal the end cap 56 into reservoir 52, the pod of Figure 3 makes use of a resilient sleeve 76 that sits atop end cap 56. Resilient sleeve 76 may be formed of a material such as silicone that is non-reactive to the e-liquid and has a high heat tolerance. Ribs can be formed in the resilient sleeve to encourage better sealing. Additionally, resilient sleeve 76 may provide a sealing interface to the inlet of the post-wick airflow passage 54 to further prevent leaking.

Date Recue/Date Received 2022-09-23 File#: OMNA 026
[0012] The above designs for pod 50 have been designed for a reservoir that stores the atomizable e-liquid as a free liquid. Efforts are made to mitigate leakage from the interface between the end cap 56 and the reservoir 52. To aid in the reduction or prevention of leaking, the ratio of propylene glycol to vegetable glycerine in the e-liquid can be adjusted to obtain an e-liquid with sufficient viscosity to reduce the likelihood of egress from the interface between the end cap 56 and the reservoir 52. It should be noted that increasing the viscosity of the e-liquid to prevent leakage is a design tradeoff as this makes transport of the e-liquid across the wick 72 more difficult. This may result in the wick 72 drying out during successive uses before it can re-wick the e-liquid.
A dry wick subjected to heating may scorch and provide a so-called burnt hit to a user, which is considered to be a bad user experience. Thus, the e-liquid is typically designed to be sufficiently viscous to reduce or eliminate leaking during normal storage and use, but no more viscous than is required.
[0013] Figures 4A and 4B illustrate the combination of two techniques to reduce e-liquid leakage. Pod 50 of Figures 4A and 4B uses both a cartomizer matrix 78 and a metallic crimp 80 at the reservoir-end cap interface. The function of these elements will now be explained in the context of the overall pod design. While Figure 4A
illustrates a cross section of pod 50, Figure 4B illustrates a bottom view of pod 50. Pod 50 has a reservoir 52 and end cap 56 as before. The end cap 56 contains electrical contacts 62 and acts to seal the open end of reservoir 52. Within end cap 56 is an inlet 64 to an airflow passage through pod 50 that continues into post wick airflow passage 54. In this embodiment, post wick airflow passage 54 may not be a molded feature within the reservoir 52.
Instead, wick 72 and heater 74 may be inserted into a cylinder made of a non-combustible (or combustion resistant) material such as fiberglass, which is then inserted into a cartomizer matrix 78 and then inserted into the reservoir 52. The heater 74 is connected to the contacts 62 so that it can receive power from a vaping device. Such a cartomizer matrix 78 may be formed of any of a number of different materials including those such as cotton, hemp, linen, wool, and nylon. In some embodiments the cartomizer matrix 78 may be made of a fabric that is wrapped into a cylindrical shape, or it may be a sponge formed of fibers such as nylon that may be blown into a mold to form a desired shape.
Those skilled in the art will appreciate that the use of a cartomizer matrix 78 may allow for the use of a less viscous e-liquid to be stored within the reservoir without incurring the Date Recue/Date Received 2022-09-23 File#: OMNA 026 same risk of leakage from the pod 50. The cartomizer matrix holds e-liquid using capillary forces. This reduces the propensity of the e-liquid to migrate out of the pod.
Wick 72 is embedded into the matrix 78, and typically exerts a greater wicking force on the e-liquid than the cartomizer matrix 78. Thus, e-liquid will be preferentially drawn across the wick 72, where its less viscous nature allows for faster re-wicking and possibly may allow for greater flavor generation. Thus, the use of a cartomizer matrix 78 can allow for the use of less viscous e-liquids without greatly increasing the likelihood of leakage.
[0014] A separate leakage prevention mechanism, often found in refillable pods, is also illustrated in Figures 4A and 4B. A metal shroud 80 is affixed to the exterior of reservoir 52 and end cap 56. It should be understood that in some discussions, shroud 80 may also be referred to as a sheath. The difference in language is often associated with whether the element is primarily designed to protect the endcap beneath, or whether it is intended to at least partially hide the endcap beneath. Regardless of the design intent, these terms should be considered interchangeable for the purposes of this disclosure. This provides another barrier to e-liquid egress, and also provides a fen-o-magnetic surface so that magnets placed within a vaping device can firmly hold a pod 50 in place within a vaping device. It should be noted that the metal shroud 80 forms a deck around the end cap 56 so as to allow for the contacts 62 to be properly exposed and to minimize the cost of offering this feature. Furthermore, metal shroud 80 is designed to not interfere with the airflow path leading into inlet 64.
[0015] Metal shrouds 80 are often provided on pods that do not make use of a cartomizer matrix, and allow end-user refilling. Metal shroud 80 provides the feeling of a premium product while aiding in the prevention of leaks from an end cap-to-reservoir interface that may not otherwise make use of proper sealing. It may also allow for the pod 50 to be held in a device using magnets. This provides a qualitatively improved pod insertion process, as there is a positive engagement of the pod 50.
[0016] In the design of a typical pod and device, it is common for the electrical contacts to be connected to other elements within the pod. Pod 50, for example, has contacts 62 connected to the heater 74. In some other examples, additional pairs of contacts are used to connect to other pod-based elements including pod-based authentication of content identification integrated circuits. In some embodiments, a single third contact is used to Date Recue/Date Received 2022-09-23 File#: OMNA 026 connect to authentication or identification integrated circuits, with the connection completed by a connection to one of the heater contacts as a common ground.
[0017] In Canadian Patent Application Serial No. 3,151,174 filed March 7, 2022 and entitled -Pod Loopback with Device Lockout" disclosed a design for a pod to function with a device that made use of lockout electrodes configured to connect a disconnected electrical component or subsystem within the device upon insertion of a pod.
[0018] It would therefore be beneficial to have a mechanism to extend the use of an end cap having a metallic component to support lockout features in a device.

Date Recue/Date Received 2022-09-23 File#: OMNA 026 Detailed Description
[0040] In the instant description, and in the accompanying figures, reference to dimensions may be made. These dimensions are provided for the enablement of a single embodiment and should not be considered to be limiting or essential.
Disclosure of numerical range should be understood to not be a reference to an absolute value unless otherwise indicated. Use of the terms about or substantively with regard to a number should be understood to be indicative of an acceptable variation of up to 10%
unless otherwise noted.
[0041] As noted above, vaping devices that provide lockout functionality have been developed to work with pods that can enable the locked out functionality upon insertion.
This can provide enhanced safety, or increased privacy, depending on the component of the vaping device that is subject to lockout. Figure 5 illustrates an example of such a vaping device 150. Vaping device 150 has a body that defines a cavity 152 sized for receiving a compatible pod. The cavity has a base 154, through which are accessible contacts 156 which are typically used to electrically connect with a pod to allow power from the battery 158 to be applied to the heater. The delivery of power from the battery 158 is modulated by switch 164 which is controlled by processor 160 in response to an input from pressure sensor 162. In some embodiments, processor 160 executes a set of control routines that are stored as at least one of software and firmware. In some embodiments, processor 160 may be replaced by control circuitry that may include pressure sensor 162 or a pressure switch. A component subject to lockout 172 has an electrical connection to another part of device 150 that runs through electrodes 166. When electrodes 166 are connected, component 172 is able to be connected to other parts of device 150, but without the insertion of a pod 100 having a loopback contact 110, component 172 remains locked out and a function of device 150 is unavailable.
[0042] It should be understood that a component subject to lockout 172 may have multiple different types of connections that can be selected for routing across electrodes 166. In one embodiment, the component subject to lockout 172 is the pressure sensor 162.
Pressure sensor 162 is typically connected to the battery 158, an electrical ground which may be associated with one of the terminals of the battery 158, and the processor 160.
The connection between the pressure sensor 162 and the battery 158 can be interrupted by Date Recue/Date Received 2022-09-23 File#: OMNA 026 having each of these components connected to one of the lockout electrodes 166. As a result, the pressure sensor 162 is not powered. A pod designed for operation with such a device may contain a loopback contact designed to facilitate a connection between electrodes 166. Accordingly, when a pod designed to electrically bridge the lockout electrodes 166 is inserted into cavity 152, the pressure sensor 162 will be connected to the battery 158, and will thus be responsive to changes in pressure associated with a user drawing on the pod. It should be understood that while in the above discussion, the connection between the pressure sensor 162 and battery 158 is routed through lockout electrodes 166, other embodiments may use lockout electrodes 166 to interrupt other connections, such as the data connection to the processor 160, or the connection to the electrical ground. In other embodiments, the component subject to lockout may be another system including the processor, a wireless subsystem (which may have an interrupted connection to any of the battery, electrical ground, the processor (in one or both directions) and an antenna), or other such systems.
[0043] It should be noted that in one embodiment, lockout electrodes 166 are a different length than electrodes 156. In the illustrated embodiment, lockout electrodes 166 are illustrated as having a longer length than electrodes 156, but in other embodiments they may be shorter or the same length. When the length of lockout electrodes 166 is sufficiently different from the length of electrodes 156, the vertical positioning of the electrical contacts on the pod may define different planes.
[0044] Lockout electrodes 166 are illustrated as being a distance D apart. As can be seen in Figure 5B, when lockout electrodes 166 (and electrodes 156) are aligned along a major axis 180, this distance D is the diameter of a circle 184 that may define the shape of a third contact on the base of a pod that will bridge electrodes 166. When device 150 is designed to work with such a pod, the lockout electrodes can be repositioned to other locations along the circumference of circle 184.
[0045] Figure 5C illustrates one such embodiment in which lockout electrodes 166 are moved off the major axis 180, but are maintained on circle 184. In the illustrated embodiment, lockout electrodes 166 define a line that is parallel to the major axis 180 and have been moved perpendicular to a minor axis 182. This puts the electrodes closer to each other, but still along circle 184.

Date Recue/Date Received 2022-09-23 File#: OMNA 026
[0046] Figure 5D shows a similar configuration as that shown in Figure 5C, but with the lockout electrodes 166 rotated by 900 so that the line defined between the lockout electrodes 166 is parallel to the minor axis and offset from the center of device 150 along the major axis 180.
[0047] It should be understood that a pod can be designed for reversible insertion into device 150, so that contacts on the base of the pod will align with electrodes 156, and so that a third contact will bridge lockout electrodes 166. Reversibility of a pod, in the current context, is associated with the design of the interface of the pod and device 150.
Given the design of an interface such as that illustrated in any of Figures 5B, 5C and 5D, reversibility is associated with the pod having rotational symmetry about its vertical axis, allowing the pod to be rotated 180 about the vertical axis and be inserted into the device 150. This effectively allows the pod to be oriented correctly when the major axis of the pod is aligned with the major axis of the device 150. Reversibility is a feature that is appreciated by many end users, but it should be understood to be an optional feature, as it is possible to define a keyed interface that only allows insertion of a pod into the device in a single orientation.
[0048] Figures 6A and 6B illustrate an embodiment of pod 100 that is designed to allow for bridging of lockout electrodes 166, while still taking advantage of the benefits of a shroud. Pod 100 makes use of a reservoir 102 having a post wick airflow passage 104 defined therethrough. Reservoir 102 has an open end that is effectively sealed through the insertion of end cap 106. End cap 106 also holds or secures electrical contacts 108, and has an airflow inlet 110 designed to allow an airflow through pod 100 by connecting with post wick airflow passage 104. Reservoir 102 can store the atomizable liquid as a free liquid, or it may make use of a cartomizer matrix within the reservoir to aid in storing the liquid. Wick 112 draws e-liquid from the reservoir 102 towards heater 114 which is electrically connected to contacts 108 so that when device 150 applies a voltage differential across electrodes 156, heater 114 will be activated and the e-liquid drawn across wick 112 will be atomized into an airflow through pod 100. Typically reservoir 102 and end cap 106 are plastic components, often formed through injection molding or another such process. An optional resilient sleeve may be placed between reservoir 102 and end cap 106 to act as a seal.

Date Recue/Date Received 2022-09-23 File#: OMNA 026
[0049] End cap 106 may make use of a resilient seal to engage reservoir 102 to prevent both leakage and movement of the end cap 106 within reservoir 102. To supplement these functions, or to replace some or all of the resilient seal, a shroud 116 can be applied to the base of pod 100. Shroud 116 can be crimped onto reservoir 102, so that its removal is difficult. Shroud 116 can serve any of a number of purposes including supplementing the functions of any seals and providing a ferromagnetic surface for magnets within device 150 to attract the pod 100. As noted above, shroud 116 may also be referred to as a sheath, and these terms should be considered as interchangeable for the purposes of naming this element that may have a functional role of at least one of protecting and at least partially obscuring the end cap 106. Where in previous examples, a shroud simply provided a deck around the perimeter of the base of pod 100, a bridge 118 is provided by shroud 116. In the illustrated embodiment, bridge 118 includes an aperture through which airflow inlet 110 is accessible. The dimensions of bridge 118 can vary with respect to the overall design, but in an embodiment, the width of bridge 118 (i.e. the length of the measurement across the major axis of pod 100) exceeds the distance D
illustrated in Figure 5A. It should be understood that this allows for all points along the circumference of circle 184 of Figures 5B 5C and 5D to be contacted by bridge 118. This allows for shroud 116 to act as a contact to bridge lockout electrodes 166 upon insertion of pod 100 into device 150.
[0050] Figures 7A and 7B illustrate an alternate embodiment of pod 100. As illustrated in Figure 7A, the structure of pod 100 is largely the same as that discussed with respect to Figures 6A and 6B. However, shroud 116 provides peninsulas 120 situated so that sufficiently large portions of the area coinciding with circle 184 are covered by peninsulas 120. This allows a variety of different device configurations to be accommodated so that lockout electrodes 166 can be electrically connected upon insertion of pod 100.
[0051] Figures 8A and 8B illustrate a further embodiment of pod 100, with a shroud 116 having a shaped bridge 118. Fold lines are illustrated in both Figures 8A and 8B to indicate that the bridge 118 has a raised section 122. This bending of bridge 118 to create an elevated section 122 allows for interaction with a device 150 that uses different electrode lengths for lockout electrodes 166 and electrodes 156.
[0052] Figure 8C illustrates the shroud 116 in cross section along cut line 8C
shown in Figure 8B. It should be noted that different parts of shroud 116 are illustrated with Date Recue/Date Received 2022-09-23 File#: OMNA 026 different colors to aid in understanding and in visual differentiation. Shroud 116 has sidewalls having a height 126 that allow for the shroud 116 to be crimped to the exterior of the pod 100. Bridge 118 extends across the width of a pod 100 (the minor axis of the pod 100). As can be seen with reference to bridge 118, shroud 116 has a thickness 128.
Within bridge 118, as noted in Figure 8B, is an elevated portion 122. This elevated portion 122 is raised above the remainder of bridge 118 and shroud 116 by a height 130.
This height differential 130, allows for the use of a device 150 with different electrode heights. By recessing portion 122, and thus aperture 132 for air inlet 110, lockout electrodes 166 can be at a different height than electrodes 156. Those skilled in the art will appreciate that contacts 108 may be situated at any of a number of different levels.
In one embodiment, the exposed surface of contacts 108 may be at or above the base of bridge 118, but below the base of elevated section 122. In embodiments where the exposed surface of contacts 108 is level with the base of shroud 116 and bridge 118, the height difference 130 may be between 0.5mm and 2mm. In some embodiments, this range forms a minimum height difference. In other embodiments, where the exposed surface of contacts 108 are not coplanar with the base of shroud 116 or bridge 118, the exposed surface of contacts 108 can be considered to define a plane, where the distance between the defined plane and the base of elevated portion122 of bridge 118 is bounded by between 0.5mm and 2.0mm at a minimum, with some embodiments defining this distance as up to 4mm. In other embodiments the distance between the defined plane and the base of the elevated portion 122 may be as small at 0.2mm, and in some embodiments it may be 0.4mm. One skilled in the art will appreciate that the closer the base of the elevated portion 122 is to being coplanar with the plane defined by the exposed surface of contacts 108, the more difficult it may be for a device to be designed to enforce this difference.
[0053] Figures 9A and 9B illustrate a further embodiment of pod 100 in which shroud 116 has a base 124 that is sized to substantively cover the base of pod 100 obscuring much of end cap 106. This base 124 is shaped to avoid interference with air inlet 110 or with contacts 108. Base 124 may be viewed as an oversized bridge 118 combined with an increase in the size of the deck provided by shroud 116.
[0054] The embodiments provided in the figures discussed above make use of a metallic shroud to provide a surface that can engage with electrodes 166 from a device 150. This Date Recue/Date Received 2022-09-23 File#: OMNA 026 allows a pod 100 having a shroud 116 to provide the functionality of a third contact that is substantially isolated from other components within pod 100.
[0055] Figures 10A and 10B illustrate a pod 200 according to an alternate embodiment of the present invention. Pod 200 has a reservoir 202, a post wick airflow passage 204 that may be integrally formed within reservoir 202 or may be a separate element, a wick 212 with heater 214 positioned for engagement with post wick airflow passage 204.
Reservoir 202 may be used to store a free liquid, or it may make use of a cartomizer matrix to aid in storing the atomizable liquid. Heater 214 is connected to contacts 208 so that when power is applied to the contacts 208, heater 214 will atomize liquid drawn across wick 212.
[0056] End cap 206 is a metallic structure. Where previously discussed pods have made use of a metallic shroud, pod 200 uses a metallic end cap 206. End cap 206 can be fitted with a resilient sleeve 220, to ensure that when inserted into reservoir 202, end cap 206 will seal the open end of reservoir 202 so that the e-liquid within pod 200 does not leak.
To allow contacts 208 to be electrically isolated from the metallic end cap 206, insulating sleeves 222 can be employed.
[0057] In some embodiments, end cap 206 can be formed from a stamped metal, with lips and recesses defined by the stamping process. In some embodiments, air inlet 210 can be recessed, and may define a set of perforations allowing for the creation of a capillary seal.
These features can provide for an end cap 206 that is electrically conductive and allows for the bridging of lockout electrodes 166 when pod 200 is inserted into device 150. In another embodiment, end cap 206 can be machined or formed through additive manufacturing. Features such as a capillary seal within air inlet 210 can be defined during these manufacturing processes. It should be understood that although illustrated here as providing a base with a single height, different heights can be achieved for an area surrounding air inlet 210, much as is shown in Figure 8C for the bridge. This may entail recessing a section during a stamping process, such as a bridge as is shown in Figures 8A-C, or in some embodiments a ring surrounding the air inlet 210, as indicated by dashed ring 224. In some embodiments, the recess is sized to be no smaller than having an inner diameter of 4.90mm and an external diameter of 6.86mm.
[0058] In the above described embodiments of pod 100 and pod 200, a metallic structure at the base of the pod is employed to provide a conductive path between points defined by Date Recue/Date Received 2022-09-23 File#: OMNA 026 the position of lockout electrodes 166 in a device 150. In some embodiments, device 150 positions electrodes 156 along its major axis 180 so that they are equidistant from the midpoint of the pod 100 (intersection of major axis 180 and minor axis 182) and spaced apart a distance between 13.5mm and 15.5mm. The lockout electrodes 166 are placed so that they reside within an annular band centered on the device with an inner diameter of 4.90mm and an external diameter of 6.86mm in some embodiments the lockout electrodes are situated 3.25mm apart and are each offset from the major axis 180 of the device 150 by 2.52mm. In other embodiments, the lockout electrodes may be located along the major axis 180 and spaced apart by 6mm.
[0059] Pod 100 and pod 200 are sized to fit within the cavity 152 of device 150. In some embodiments, pod 100 and pod 200 may be formed with a long side (also referred to as a major axis) dimension of 22.35mm and a short side (also referred to as a minor axis) dimension of 13.17mm. In such an embodiment, the electrical contacts 108 and 208 are positioned so that an exposed face is present on the base of the pod 100, 200 to connect to the electrodes 156. The lateral positioning of the contact 108, 208 is a function of the size of the contact. With larger contacts, the positioning of each contact can be varied so long as the exposed surface of the contact allows for engagement with the electrode 156. The metallic base of pod 100 or pod 200, provided by structures within shroud 116 or end cap 206 respectively, should provide an electrically conductive surface to allow lockout electrodes 166 to be conductively connected. The material choice for the metallic base of pod 100 or pod 200 may vary across embodiments according to the requirements of device 150 and the component to be locked out 172. In some embodiments, device has a pressure sensor 162 that is configured so that its connection to battery 158 is routed through lockout electrodes 166. Battery 158 is expected to provide an output voltage that may vary between approximately 4.2V and 3.0V, and the expected voltage drop across electrodes 166 is expected to be in the range of lmV and 3mV. Thus, the metallic base of pod 100 or pod 200 should provide a suitable resistance such that the voltage drop is less than 3mV, and in some embodiments may be no lower than ImV, between two points that coincide with the locations of the lockout electrodes. It should be understood that the distances disclosed above may vary by up to the greater of 10% or 0.1mm.
[0060] The design of a vaping device 150 having lockout electrodes 166 having different heights than electrodes 156 may, in part, seek to ensure that a pod 100, 200 having one of Date Recue/Date Received 2022-09-23 File#: OMNA 026 a conductive endcap 206 or a conductive shroud 116 covering a conventional non-conductive endcap 106 is properly designed for use with the device 150. If this cannot be determined, as a safety feature, device 150 may remain non-operative. To prevent the use of such a pod 100, 200 a device 250 having an electrical configuration as shown in Figure 11A may be employed. Device 250 has a pair of electrodes 256 connected to opposite ends of a battery 258. A processor 260, upon receipt of a signal from a pressure sensor 262, controls delivery of power from battery 258 to electrodes 256 through use of switch 264. As noted above, in some embodiments, switch 264 can be replaced by, or supplemented with, a signal generator.
[0061] As with the previously illustrated embodiments, when a pod is inserted into the device 150, lockout electrodes 266 will be bridged and a component to be locked out, in this illustrated embodiment pressure sensor 262, is enabled. However, an additional electrode, a fifth electrode 286, is present. This bypass detection electrode 286 is positioned so that if a pod with an otherwise conductive end cap is inserted into device 250, a second electrical pathway is provided for any current introduced by one of the lockout electrodes 266. As such, this fifth electrode 286 may also be referred to as a bypass detection electrode. In the illustrated embodiment, bypass detection electrode 286 acts as an input to a battery charge controller 290. Thus, if a pod is inserted that bridges Vcc to bypass detection electrode 286, for example through connecting through one of lockout electrodes 266, current will flow from the battery 258 through Vcc lockout electrode 266 to electrode 286 and then into battery charge controller 290.
[0062] When charge controller 290 detects an input current, it typically advertises that the device 250 is being charged, in some embodiments this is done through providing a charging indication to the processor 260. Device 250 also typically displays a charging indicator to the user through control of a Light Emitting Diode (LED) or other such display element. When the device 250 is charging, use of the device 250 to vape is often disabled to prevent undue stress on the battery 258. Thus, by connecting bypass detection electrode 286 to the charge controller 290, device 250 can be prevented from activation.
Although schematically illustrated in Figure 11A as being located between one of the power electrodes 256 and lockout electrodes 266, it should be understood that the placement of bypass detection electrode 286 can be varied.

Date Recue/Date Received 2022-09-23 File#: OMNA 026
[0063] Figure 11B illustrates a top view of a device 250. Pod cavity 252 has a base 254 and is defined by a sidewall of device 250. Cavity 252 is sized and shaped to receive a physically compatible pod. Device 250 has power electrodes 256 for delivering power to a heater within a compatible pod. Lockout electrodes 266 are shown as being situated within an annular ring centered on the middle of the base 254. This optional placement facilitates the connection of these lockout electrodes 266 to a loopback contact on the base of the pod that is positioned to coincide with the illustrated annular ring. Also shown is a placement for a structure 288 designed to allow airflow around the base of an inserted pod to communicate with the pressure sensor 262 within device 250. Structure 288 may in some embodiments comprise a raised pillar having an aperture positioned above the base 254 so that if a liquid pools on base 254 it cannot easily enter the aperture.
[0064] As shown in previous figures, the location of electrodes 256 can be varied. The symmetrical location of these electrodes 256 with respect to the center of the base 254 allows for a simplified design that allows for pod reversibility. Where a pod is designed with a third contact designed to connect the lockout electrodes 266, the location of the lockout electrodes can be varied, but is restricted to a position that will engage with the positioning of the third contact, as illustrated by the dashed lines forming rings. In the illustrated embodiment, the location of the lockout electrodes 256 can be varied within the illustrated ring. The positioning of fifth electrode 286 can also be varied, but is preferably situated outside the area denoted by the annular ring. This positions the fifth electrode 286 in a location that would otherwise not make contact with a surface that would electrically connect the fifth electrode 286 to the lockout electrodes on a pod without a conductive end cap.
[0065] Figure 11C illustrates an alternate embodiment of device 250 in which bypass detection electrode 286 is colocated with pressure sensor protection structure 288. The height of the fifth electrode 286 should be sufficient to ensure contact with the base of the pod when inserted into device 250.
[0066] To allow a metallic endcap to operate in conjunction with device 250, modifications to the profile of the end cap are required. Pod 300, as illustrated in Figures 12A, 12B and 12C provide illustrative designs that would allow a pod 300 having a conductive base 316 to function when inserted into device 250.
Date Recue/Date Received 2022-09-23 File#: OMNA 026
[0067] Figure 12A illustrates a pod 300 having a non-conductive end cap 306 with a conductive base 316 on the exterior face of the base of the pod 300.
Electrical contacts 308 are set under the conductive base 316, and are surrounded by the non-conductive end cap 306. The surface of conductive base 316 is set away from end cap 306 a sufficient distance to allow for airflow into the pod to pass from the area around the contacts 308.
This optional design feature allows for a distinct airflow inlet to be omitted in conductive base 316. To allow for the fifth electrode 286 to be electrically isolated from the lockout electrodes 266, an aperture 332 is provided, so that bypass detection electrode 286 contacts the non-conductive end cap 306. The aperture 332 may also create an inlet for airflow between the conductive base 316 and the non-conductive end cap 306. It should be understood that in some embodiments, a conventional airflow inlet may be provided through an appropriately situated aperture on conductive base 316. It should be understood that in relation to the electrode configuration of Figures 11B and 11C, lockout electrodes 266 would contact the annular region 342. It should be understood that annular region 342 need not be specially indicated or constructed with respect to the conductive base 316, but is instead illustrated for understanding of the region in which lockout electrodes 266 of Figures 11B and 11C would contact the pod 300.
[0068] Figure 12B illustrates an alternate embodiment of pod 300 in which aperture 332 is replaced by a domed section 334 of conductive base 316. Domed section 334 moves a portion of conductive base 316 so that when pod 300 is inserted into device 250, the fifth electrode 286 will not make contact with the conductive base 316.
[0069] Figure 12C illustrates a further alternate embodiment of pod 300 in which in place of aperture 332 or domed section 334, fifth electrode 286 is prevented from electrical contact with the conductive base through a coating 336 applied to at least a portion of conductive base 316. In some embodiments, coating 336 may be a paint, which in some embodiments may be substantially transparent, while in other embodiments it may be a plastic or other non-conductive coating in the form of a sticker applied to the conductive base 316.
[0070] In another embodiment shown in Figure 12D, conductive base 316 can have a ring 338 that separates base 316 from the section 340. This ring 338 creates distinct surfaces within conductive base 316 that are not in electrical contact with each other, thus Date Recue/Date Received 2022-09-23 File#: OMNA 026 preventing an electrical connection between fifth electrode 286 and the lockout electrodes 266.
[0071] Through any one or more of the application of a coating 336, the use of a domed section 334, an aperture 332, a ring 338 that disrupts the electrical connectivity of sections of conductive base 316, or other such techniques, the conductive base 316 is prevented from electrically connecting the fifth electrode 286 of device 250 to the lockout electrodes 266. In some embodiments, this can be understood to be an electrical separation between the connection of the fifth electrode 286 and the area within the dashed lines forming annular ring 342. By creating a barrier between these two, the electrical connection that would otherwise disable the device 250 is prevented. Aperture 332, domed section 334, coating 336 and ring 338 can each be considered an embodiment of a patch that does not allow for electrical conductivity between positions within the patch and the portions of the base 316 that would otherwise allow for electrical connection to the lockout electrodes 266 (e.g. positions within annular ring 342).
[0072] Those skilled in the art will appreciate that in Figures 12A-12D, features 332, 334, 336 and 338 break the symmetry of the pod given their current positions. To enable a pod 300 with a reversible design, each of these features may need to be duplicated and placed in a mirrored position to allow for the pod to be rotated 180 and still provide proper positioning of the features with respect to the corresponding elements in the device 250.
[0073] Figure 13 presentes an alternate electrical configuration for device 250. As shown and discussed in previous Figures, device 250 has electrodes 256 connected to battery 258, with at least part of the connection including a switch 264 that is controlled by processor 260. Lockout electrodes 266 connect a component subject to lockout to another component in the device 250. As illustrated, the component subject to lockout is a pressure sensor 262. While in some embodiments, the connection between the pressure sensor 262 and processor 260 may be routed through lockout electrodes 266, in the illustrated embodiment it is the connection between power from battery 258 (indicated as Vce) that is routed through the lockout electrodes 266. Thus, without insertion of a pod that will electrically connect lockout electrodes 266, the pressure sensor 262 will remain unpowered, and device 250 will not activate.
[0074] As shown in Figure 13, fifth electrode 286 is connected as an input to processor 260. If a pod is inserted into device 250 that connects fifth electrode 286 to at least one of Date Recue/Date Received 2022-09-23 File#: OMNA 026 the lockout electrodes, processor 260 will receive a high voltage signal on at least one of its inputs. This can act as a flag indicating that the device should not activate, much as a signal from a charge controller functions as described in relation to Figure 11.
[0075] Figure 14 illustrates an alternate electrical configuration for device 250, in which fifth electrode 286 is connected to the battery 258. In the presence of a connection between fifth electrode 286 and the lockout electrode 266 connected to battery 258 and represented by Vcc, a pathway taking power from the K, lockout electrode 266 directly back to the battery 258 is provided. This will prevent sufficient power from being delivered to pressure sensor 262 to allow for activation. In some embodiments, this connection will be detected as a short circuit and will trigger a short circuit protection circuit that will prevent the device 250 from operating.
[0076] It should be understood from the above electrical designs, that the addition of a fifth electrode that when connected to at least one of the lockout electrodes can be used to generate a signal indicative of an unauthorized pod. This allows the device 250 to detect a pod that does not have an authorized design. The detection of such a pod may be treated as a safety risk, as the device 250 has not been designed to operate with the pod in question. Accordingly, the device 250 may remain locked out, thus preventing delivery of voltage across the electrodes 256. Those skilled in the art will appreciate that in some embodiments the vaping device 250 may make use of one or both of hardware and software features to perform this lockout.
[0077] Although a pod designed for use with device 250, and thus having both a contact to connect lockout electrodes 266, and a non-conductive surface for engaging with fifth electrode 286 will function, other embodiments, such as those illustrated in Figures 12A-12D may also be used. These pods have a substantially conductive base 316 but have a section designed to prevent electrical engagement with a fifth electrode. This section is electrically isolated from a section corresponding to the location at which lockout electrodes will contact the pod. In some embodiments, the location at which lockout electrodes will contact the pod is defined by an annular ring having an external diameter of 6.86mm and an internal diameter of 4.9mm. In some embodiments, this annular ring is centered on the base of the pod. The provision of a non-conductive surface may include the provision of an aperture in the conductive base, the provision of a non-conductive coating on the non-conductive base, a domed section on the non Date Recue/Date Received 2022-09-23 File#: OMNA 026 conductive base, and other such features that will prevent electrical connection to a fifth electrode.
