Description

[0001] The present disclosure relates to capsules containing consumable materials, specifically but not limited to capsules for use with electronic hookah devices. Background Art

[0002] Electronic hookah pots or hookah pipes provide a convenient means for hookah products. An exemplary prior art hookah device is shown in WO 2015 / 172224. The device is configured to heat a capsule containing a smoking product (e.g., a fruit tobacco blend or shisha). The capsule is received in a heating chamber of the device so that the smoking product is vaporized and / or combusted to produce an aerosol that the user can inhale.

[0003] The inventors have found a number of problems with such prior art devices. Typically, such devices heat the capsule at a predetermined fixed temperature. This temperature can be optimized for a standard composition of the smoking product.

[0004] If the composition of a given smoking product deviates from the standard composition, the smoking experience may be sub-optimal. For example, if the smoking product includes components configured to vaporize at a low temperature, heating the product at the standard temperature may cause the product to combust. Conversely, if the components are configured to vaporize at a high temperature, the standard temperature may result in a weak-tasting smoke. Thus, conventional devices limit the compositions suitable for use therewith, and the use of non-standard capsules may present a poor experience for the user.

[0005] Prior art capsules are configured to be substantially sealed. This preserves the freshness of the components. Once the smoking product is depleted, the capsule is discarded. However, some users may refill the capsule with smoking products from different sources. For example, this can be problematic in cafes or bars, etc., because the capsule may be refilled with a poorer or less fresh smoking product compared to the smoking product that would be provided in a sealed capsule. This can result in a poorer smoking experience for the user, and / or the system may produce harmful compounds due to incorrect or overheating of the smoking product.

[0006] Once the smoking session has been completed, the user may inadvertently heat an empty capsule and / or forget to deactivate the device. If the user attempts to draw air from the device while a used capsule is being heated, this can damage the device, pose a fire risk, or present an adverse health risk to the user.

[0007] It is an object of the present invention to overcome or ameliorate one or more of the above problems. Summary of the Invention

[0090] Figure 1 An example of a water pipe device 2 is shown, herein referred to as a hookah device or hookah pipe, although it will be understood that the pipe can be used for vaporizing and inhaling a variety of consumable substances. In this example, the device 2 is electrically heated and / or electronically controlled.

[0091] The water pipe device 2 includes a base 4. The base 4 can provide a wide portion or area to prevent the device 2 from tipping over. An electronics compartment 6 is provided. The device 2 includes a reservoir 8 configured to be filled with a liquid coolant (e.g., water). The reservoir 8 thus provides a container / reservoir. The electronics compartment 6 and the reservoir 8 can be separable / detachable. This allows access to the opening in the reservoir 8 for filling / emptying.

[0092] The electronics compartment 6 includes a cover 12 to provide an opening therein. As Figure 2 shown, a heater 10 is mounted within the electronics compartment 6. The heater 10 is configured to receive a capsule 14 that includes a consumable / smoking product. The heater 10 heats the capsule 14 to vaporize or otherwise disperse one or more components of the consumable product. The heater 10 thus forms a heating chamber or heating container. One or more heating elements may be provided on, within, and / or integral with the walls of the heating chamber 10. The heating chamber 10 includes a thermally conductive material (e.g., metal). The capsule 14 forms a tight fit with and / or engages the heating chamber 10. Thus, in use, heat passes through the walls of the heating chamber 10 into the capsule 14.

[0093] Typically, the heating element includes a resistive element (i.e., heated by the current flowing through it). However, any suitable device can be used to heat the heating chamber 10 and / or the capsule 14, such as one or more of the following: inductive heating; microwave heating; infrared heating; convective heating (e.g., the heating element is displaced away from the wall of the heating chamber 10); electronically controlled combustion heating (e.g., using gas or other fuel); and / or oil heating. The heating chamber 10 includes a thermally conductive material (such as metal).

[0094] As best seen in Figure 3 a plurality of orifices 16 are provided in the capsule 14 to allow the evaporated product to escape therefrom. The diameter of the orifices 16 is typically less than 5 mm. During heating of the capsule 14, the evaporated product enters the heating chamber 10. The lid 12 and / or the heating chamber 10 includes one or more air inlets 17 to allow air to enter the heating chamber. Then, in the heating chamber 10, this air is mixed with the evaporated product.

[0095] The heater 10 can be controlled by electronics in the electronics compartment 6 (e.g., via a heater controller). These electronics can include a microcontroller / microprocessor, memory (volatile and / or non-volatile), and / or electrical regulation circuitry (such as a power limiter and / or controller). The electronics compartment 6 includes any suitable components to provide heating of the heater 10. A power supply is provided. The power supply can be mains-powered. Additionally or alternatively, the power supply includes a battery, etc. The battery can be removable and / or rechargeable. A power switch 18 can be provided. The device 2 and / or the heater 10 can thus be manually started / stopped. Additionally or alternatively, the heater 10 can be started / stopped by means of a locking or closing mechanism configured to engage or secure the lid or other components of the heating chamber, thereby forming a safe enclosure around the heater in use. When the lid is open or unlocked / unlatched, the heater can be inoperable.

[0096] The heating chamber 10 is operatively connected to the reservoir 8 via a conduit 15 passing through the electronics compartment 6. Thus, the evaporated smoking product passes through the coolant in the reservoir 8 via the conduit 15 and is cooled and / or filtered therein. The conduit 15 passes through the electronics compartment 6. The conduit 15 is sealed with the electronics compartment 6 to prevent its contamination.

[0097] A suction hose 20 is provided to communicate with a portion of the reservoir 8 above the coolant level. The suction hose includes a mouthpiece 22. The mouthpiece 22 can be detachable / removable. Air can be drawn through the heated capsule, and the evaporated product in the capsule can be carried by the airflow through the conduit 15. Thus, the user can inhale to draw the evaporated product through the device 2 and discharge it through the hose 20. Such a system mimics a traditional non-powered hookah / hose pipe.

[0098] It will be appreciated that Figure 1 and Figure 2 the device 2 shown in is merely exemplary, and any suitable such device may be used. In some embodiments, the electronics compartment 6 may be provided below the coolant tank 8 such that, in use, the vaporized smoking product passes upwardly through the device 2. Accordingly, the electronics compartment 6 may form the base portion of the device 2. The conduit 15 may extend from the heater and upwardly into the coolant to allow the vaporized product to enter therein. The capsule 14 may be inserted into the base of the device 2.

[0099] Examples of suitable hookahs 2 and associated heaters 10 may be found in the earlier published patent applications WO 2017 / 080545 A1 and WO 2015 / 172224 A1, the contents of which are incorporated herein by reference. They are not described in detail herein.

[0100] Referring to Figure 3 and Figure 4 , the capsule 14 includes a top wall 24 and a bottom wall / base 26. The top wall 24 and the bottom wall 26 are connected via side walls 28. The side walls 28 are substantially continuous. Accordingly, the top wall, bottom wall and side walls provide an enclosure / cavity for the smoking product 30. It will be appreciated that the terms "top", "bottom" and "side" are only used to assist in describing the capsule, and the capsule may be used in any suitable orientation in use.

[0101] A plurality of orifices 16a, 16b are provided in the top wall 24 and the bottom wall 26 respectively. During use, air passes through the orifices in the top wall 24 and into the smoking product 30 / through the smoking product 30. The smoking product 30 is heated and vaporized. The air entrains the vaporized product in the capsule 14 and exits through the orifices in the bottom wall 26. Such an arrangement provides a pre-packaged or pre-filled capsule.

[0102] In some embodiments, the orifices 16 may be provided in only one of the top wall 24 and the bottom wall 26. Accordingly, air enters and exits the capsule via the same orifices 16. In some embodiments, the orifices 16 may be provided in the side walls 28. It will be appreciated that any suitable arrangement may be provided to allow the vapor to flow out of the capsule 14. However, this arrangement is advantageous as it allows the capsule 14 to be heated via the side walls 28 and allows air to pass through the top / bottom of the capsule 14. This may help to ensure that the air flowing through the capsule 14 does not interfere with its heating.

[0103] In some embodiments, device 2 is configured to pierce, perforate, or otherwise open capsule 14 to allow air to enter / exit. Thus, capsule 14 can be sealed prior to opening. This can help maintain freshness. The top wall can be pierced by a suitable construction in lid 12 and / or the bottom surface can be pierced by one end of smoke conduit 15. Thus, the orifice need not be formed during manufacture, but can be formed during use of the capsule.

[0104] Capsule 14 can include a seal 32 to cover orifice 16. The seal is removed prior to use to expose orifice 16. Seal 32 thus helps maintain freshness. Seal 32 can be suitably disposed on the top / bottom / side surface. The seal can be attached to capsule 14 using a peelable adhesive or the like. Seal 32 can include a pull tab or the like.

[0105] According to aspects of the present invention, the entire capsule (with or without one or more seals 32 over orifice 16) can be maintained in a sealed bag, package, or sleeve to provide a retail item that can keep the capsule in a fresh state for a longer period of time. The bag can be filled / flushed with an inert gas such as nitrogen. Thus, either or both of the capsule and the bag can be filled with gas to help preserve the smoking product therein until use. Even if the capsule itself is air-filled or unflushed, it has been found that flushing the bag with a suitable gas may be sufficient. For example, if the gas in the bag can mix with the air inside the capsule such that the total oxygen content inside the bag is low enough to contribute to a long capsule shelf life. If desired, the bag can have a metal / foil layer, for example, as well as a polymer layer.

[0106] The top surface 24 can include a closure (such as a lid). This allows product 30 to be placed into capsule 14. Orifice 16a can be provided in the lid or may not be provided in the lid. The closure is then secured to the capsule to hold product 30 therein. The closure can be secured to the upper edge of sidewall 28. Sidewall 28 can include an outwardly extending rim / flange 34. The closure can engage rim / flange 34 and seal to rim / flange 34 and / or deform against rim / flange 34. Lid 12 can engage rim 34 and / or a closure attached thereto to form a seal therebetween. Rim 34 can be curled and / or include a reinforcing element. Rim 34 can be planar and / or annular. Rim 34 can be parallel to top surface 24 and / or bottom surface 26.

[0107] The closure can be permanently secured to capsule 14 to prevent product 30 from being removed from the capsule. For example, the closure can be crimped or adhered to capsule 14. The closure can be crimped onto / over rim 34.

[0108] In other embodiments, the closure may be releasably connected to the capsule 14 to allow a user to access the interior of the capsule 14 (i.e., to refill the capsule 14). The closure may be connected to the capsule via a releasable connecting means. The releasable connecting means may include one or more of the following: an interference fit; a snap fit; a thread; a releasable latch or clip; a clamp; a hook and loop; a pressure post; a dowel pin; etc.

[0109] In this embodiment, the bottom surface 26 is integrally formed with the capsule 14 (i.e., integral with the sidewall 28). The orifice 16b is thus formed in the capsule 14. In an alternative embodiment, the bottom surface 26 may include a permanent / removable closure.

[0110] The capsule 14 includes a top wall 24 that is larger in area than the bottom wall 26 in a plan view, such that the capsule tapers / narrows in form. The capsule 14 tapers towards the bottom wall 26. This facilitates release from the heating chamber 10. Accordingly, the cross-section of the capsule 14 (from a side view) is trapezoidal. The tapering shown in the figure is merely illustrative, and the sidewall 28 may taper at any suitable angle. For example, the sidewall 28 may taper between 1 degree and 45 degrees, preferably between 1 degree and 30 degrees, preferably between 3 degrees and 20 degrees. Generally, the sidewall 28 tapers by at least 1 degree, preferably at least 3 degrees.

[0111] The capsule 14 includes a circular profile (from a top view). Accordingly, the capsule 14 is frustoconical. However, it will be understood that the shape of the capsule 14 is merely exemplary, and the capsule may include any suitable shape for the intended purpose. Different shaped capsules may be provided to achieve a desired contact with the interior of the device 2. For example, the capsule may be shaped for good thermal contact with the heater 10. For example, an oval or polygonal capsule in a plan view may be accommodated.

[0112] The capsules 14 are stackable. The upper and lower surfaces of the capsules 14 may include complementary recesses / projections to facilitate stacking. For example, the base may have ridges / projections configured to engage with grooves / recesses on the upper surface 24 and / or the rim 34, and vice versa.

[0113] In the case where the capsules 14 are stackable, multiple capsules may be simultaneously introduced into the heating chamber of the device during the same usage smoking session. The capsules 14 may jointly define a generally continuous fluid passage therethrough. Depending on preference, this may provide the user with a customized combination of active ingredients, components, and / or flavors.

[0114] The capsule 14 includes a heat-resistant material. Thus, the capsule 14 is stable at the heating temperature of the device 2. The capsule 14 includes a metallic material, such as aluminum. The metallic material ensures sufficient heat conduction into the capsule. In other embodiments, the capsule 14 may include a ceramic material. The capsule 14 may include a coating. The coating may include a colored pigment or the like. The coating is temperature-stable (i.e., does not decompose at high temperatures).

[0115] A second embodiment of the capsule 14 is shown in Figure 5 and Figure 6 . The second embodiment may be substantially the same as the first embodiment, and similar features will not be described in detail. The lower wall 26 and the side wall 28 are continuous to form a curved base. The wall 26 curves inwardly such that the capsule 14 tapers towards its lower end.

[0116] The base / lower wall 26 of the capsule 14 includes a recess 36. The recess 36 extends towards the upper edge of the capsule 14. Thus, the recess 36 extends into the capsule 12. The recess 36 is curved / arcuate. Thus, the base 26 of the capsule 12 is dome-shaped. The recess 36 includes a plurality of holes 16b extending through the wall of the base 26. In use, these apertures allow air / vapor to pass through the capsule 12 (i.e., to provide a unidirectional air flow). In use, the smoking product 30 is filled to a position below the apertures 16b of the recess such that liquid or other smoking product does not flow through the apertures. A removable seal 32 may extend across the recess 36. Another seal 32 may seal the upper end of the capsule 14.

[0117] Referring to Figure 7 , the capsule 14 includes an indicator 40. Generally, the indicator 40 is configured to indicate or otherwise communicate one or more properties of the capsule 14 and / or its contents. In a specific embodiment, the indicator 40 indicates a specific formulation of the smoking product 30 and / or its heating profile. The indicator 40 may thus provide a label, marking, etc. The content of the indicator 40 will be described in detail later.

[0118] In the first embodiment, the indicator 40 includes an electronic memory device. The indicator 40 and / or the data therein can thus be electronically read, downloaded, and / or otherwise interrogated via a sensor 42 on the hookah device 2 (see Figure 8 ). The memory device may include any suitable form. Generally, the memory device is non-volatile / persistent. Thus, the data on the memory device is retained even without power. The memory device may include EEPROM, flash memory, or other suitable technology. The memory may store at least 32 bits of data; preferably at least 128 bits of data; preferably at least 256 bits of data. The data may be stored with or without encryption. The indicator includes a memory controller to control the reading / writing of the memory and / or to control communication with the sensor 42.

[0119] In some examples, the memory device 56 includes a read-only memory (ROM). This prevents unauthorized tampering with the data on the indicator 40. Although the physical memory may be rewritable, the indicator 40 itself and / or any external device (e.g., the hookah device 2) may prevent writing to and / or rewriting of data on the storage device 56.

[0120] In Figure 8 the illustrated embodiment, the indicator 40 is configured to make physical contact with a sensor 42 on the device. This provides a "wired" or "contact" system. The indicator 40 is disposed on an external portion of the capsule 14 to allow contact with the device 2. The indicator 40 may be disposed on the side wall 28, the bottom wall 26, and / or the top wall 24 of the capsule 14. Preferably, the indicator 40 is disposed in the bottom wall 26 because this prevents interference with the heat flow into the capsule 14 via the side wall 28 of the capsule 14. In some embodiments, the indicator 40 is disposed on a portion of the capsule 14 that protrudes therefrom, such as the rim 34. Thus, in use, the indicator 40 is external to the heating chamber 10.

[0121] The device sensor 42 is disposed in a position corresponding to the indicator 40 to provide contact with the indicator 40 in use. The sensor 42 is thus disposed on / within the heating chamber 10. The sensor 42 may be disposed on the lower end portion 44 and / or the side wall 46 of the heating chamber 10. The sensor 42 may be aligned with the indicator 40. The sensor 42 may be in the same plane / parallel to the indicator 40.

[0122] In some embodiments, the sensor 42 is disposed on the lid 12. The sensor 42 is thus disposed on a movable closure for the heating chamber 10. The indicator 40 is correspondingly disposed on the upper surface 24 of the capsule 14. This may prevent damage to the indicator 40 because the temperature of the upper surface 24 is typically lower than the temperature of the remainder of the capsule 14 in use. The indicator 40 may be disposed offset from the center of the capsule 14. For example, the indicator 40 is disposed adjacent to the side wall 28 of the capsule 14. This may reduce disruption / blockage of the inlet orifice 16a. In other embodiments, the indicator 40 / sensor 42 is disposed in the center of the capsule 14 such that the capsule 14 may be disposed in any orientation. The sensor 42 may be operatively connected to the electronics compartment 6 (see Figure 2 ).

[0123] Due to the high temperature in the heating chamber 10, it is understandable that a device or system 48 configured to read / interrogate the indicator can be shifted away from the sensor 42 to prevent damage to it. Thus, the sensor 42 can include only one or more electrical contacts, etc. Then, the sensor 42 is operatively connected to the sensor device 48 (e.g., via a cable 50, etc.). The contacts can be biased to engage with the indicator 40. This improves the electrical contact therewith. The contacts can be spring-mounted or spring-loaded. The contacts can be gold-plated, etc. In the case where the indicator 40 is disposed on the edge 34, the cover 12 can bias the sensor 42 to engage with the indicator 40. For example, the indicator 40 / sensor 42 is between the cover 12 and the edge / outer edge 52 of the heating chamber 10.

[0124] In some embodiments, the communication between the device 2 and the capsule 14 is wireless. Figure 10A and Figure 10B Such an arrangement is shown in. Thus, the sensor 42 is configured to communicate wirelessly with the indicator 32. The sensor 42 includes a wireless communication transmitter and / or receiver. The indicator 40 correspondingly includes a wireless communication transmitter and / or receiver. For example, the sensor 42 and / or the indicator 40 includes an antenna, etc.

[0125] In some embodiments, the indicator 40 includes a passive device. The indicator 40 does not include a dedicated power source. The sensor 42 is configured to transmit a signal (i.e., an interrogation signal) to the indicator 40. The indicator 40 then uses the signal power to power the electronics within the indicator 40 and transmit a return signal. Then, the sensor 42 receives the return signal. This can provide a radio frequency identification (RFID) system, etc. This allows the indicator 40 to be low-cost and simple in structure.

[0126] The sensor 42 can be configured to transmit interrogation signals at a predetermined interval (e.g., when the system is powered on). This allows the sensor 42 to detect when the capsule 14 is received within the device. Typically, the interval is between 0.1 second and 1 second. In other embodiments, the interrogation signal is provided via a user manual input. For example, the user can press a button to activate the interrogation signal. Then, the sensor 42 can transmit a predetermined number of interrogation signals; repeat transmitting the interrogation signal for a predetermined period of time; and / or repeat transmitting the interrogation signal until the user releases / deactivates the manual input.

[0127] In other embodiments, the indicator 40 includes an active device. The indicator 40 thus includes a dedicated power source (e.g., a battery). The indicator 40 is configured to transmit a signal. The signal can include an identification signal or a handshake, etc. Then, the signal is received by the sensor 42. Then, the sensor 42 can transmit and confirm the signal. The indicator 40 can then transmit the data contained therein. In other embodiments, the indicator 40 can transmit only the data without a handshake arrangement (e.g., broadcast the signal).

[0128] Wireless communication can use any suitable radio frequency, such as: LF, HF, UHF, and / or microwave frequencies. Wireless communication is typically short-range, e.g., less than 100 cm; preferably, less than 50 cm; preferably, less than 5 cm. For example, the system can use Near Field Communication (NFC). This ensures that the correct capsule is interrogated by the sensor 42 and / or reduces power consumption. The power of the wireless communication system can be less than 1 W.

[0129] It will be appreciated that the wireless sensor 42 and / or any associated reading device 48 are positioned at / within any suitable location to read the indicator 40. The sensor 42 can be disposed near or adjacent to the heating chamber 10 and / or disposed within the lid 12. The sensor 42 can be displaced away from the heating chamber 10 (i.e., its surface) and / or the capsule 14. Generally, the sensor 42 is housed within the electronics compartment 6. The heating chamber 10 can be configured to allow wireless transmission therethrough. For example, the heating chamber 10 can include an aperture or a non-conductive portion (e.g., ceramic) to allow transmission therethrough.

[0130] Thus, the wireless indicator 40 can be disposed at / within any suitable location on / in the capsule 14. Generally, the indicator 40 is disposed on an outer portion of the capsule 14 (e.g., on the lower wall 26, upper wall 24, or side wall 28). This allows for easier wireless transmission. In an alternative example, the indicator 40 is housed within the capsule 14. The indicator 40 can be fixed to the inner side of the wall of the capsule, within its internal compartment, or loosely housed within the wall of the capsule.

[0131] In Figure 10B In the specific embodiment shown, the indicator 40 is disposed on the edge 34 of the capsule 14. The indicator 40 can be disposed on the lower side 35A of the edge 34 (i.e., the side facing the side wall 28 and / or the lower wall). Additionally or alternatively, the indicator 40 is disposed on the upper side. The indicator 40 can be fully or partially embedded within the edge 34. For example, the indicator 40 can be flush with the surface of the edge 34. The indicator 40 can extend around the perimeter or circumference of the edge 34. The indicator 40 can thus be arcuate, angled, or otherwise convex / bent. The indicator 40 can extend partially or fully around the edge 34.

[0132] As Figure 10CAs shown, the sensor 42 is accordingly positioned to read the indicator 40. The sensor 42 is disposed adjacent to the heating chamber 10. The sensor 42 is disposed on or adjacent to the shoulder / edge / outer edge 52 of the heating chamber 10. Alternatively, the sensor 42 is disposed on / in the lid 12. The indicator 40 and / or the sensor 42 are thus removed from the heating zone and / or the smoke path of the capsule 14. This can help prevent it from being contaminated by particulate matter in the vaporized smoking product and / or heat that can damage the sensor 42.

[0133] The indicator 40 includes a thickness that ensures that the wall 28 of the capsule 14 remains in contact with the wall 46 of the heating chamber 10. Similarly, this thickness allows the edge 34 to lie flat against the edge 52 of the heating chamber. The indicator 40 includes a thickness that is less than or equal to 1 mm, preferably less than or equal to 0.5 mm.

[0134] Referring Figure 10D , the indicator 40 can be attached to a carrier 55. The carrier is mounted to the side wall 28 of the capsule 14. Thus, the carrier 55 can be mounted circumferentially. The carrier 55 can be disposed adjacent to or contiguous with the edge 34 of the capsule. The carrier 55 generally wraps around the capsule 14. Thus, the carrier 55 is annular or ring-shaped. The carrier 55 can provide a collar, band, or sleeve. In some embodiments, the carrier 55 can partially wrap around the capsule 55 (e.g., the carrier 55 is crescent-shaped or C-shaped).

[0135] The carrier 55 is polymeric. The carrier 55 can include any suitable polymer. The carrier can include a high-temperature thermoplastic. This prevents it from burning or decomposing during heating. The carrier 55 can include one or more of the following: polyphenylene sulfide (PPS); polyethersulfone (PESU); polyphthalamide (PPA); polysulfone (PPSU); polyurethane; silicone; and combinations thereof. The polymer generally contains at least one aromatic functional group.

[0136] The carrier 55 is removable / separable from the capsule 14. This allows for separate recycling / processing of the carrier 55 and the capsule 14. The carrier 55 can form an interference fit / friction fit. Thus, the carrier 55 remains in place on the capsule 14 loosely (i.e., not permanently fixed to the capsule). The carrier 55 is sized to provide a close / tight fit with the capsule. This allows for easy removal thereof. In other embodiments, the carrier 55 is permanently fixed to the capsule 14, for example, using an adhesive, fasteners, etc.

[0137] In some embodiments, the indicator 40 is disposed on a tab 57 of the carrier. The tab 57 provides a flap, lip, or protrusion that extends outwardly from the carrier 57. The tab 57 extends outwardly in a direction generally the same as the edge 34 of the capsule 14. The tab 57 is thus disposed adjacent or contiguous to the edge 34. The tab 57 protrudes away from the sidewall 28 of the capsule, thereby preventing interference from the metal in the sidewall 28 when the indicator 40 wirelessly communicates with the sensor 42.

[0138] The tab 57 extends only around a portion of the perimeter of the capsule 14. For example, the tab 57 may extend around the perimeter of the capsule 14 by about 45 degrees. The tab 57 thus provides a separate portion. In an alternative embodiment, the tab 57 extends around the entire perimeter of the capsule. The tab 57 may thus form an edge or flange. The indicator 40 may thus be curved / arcuate, as Figure 10B shown.

[0139] The indicator 40 is at least partially embedded within the tab 57. Preferably, the indicator 40 is fully embedded / encapsulated within the tab 57. This helps prevent damage to the indicator 40. The indicator 40 may be insert molded or overmolded to the tab 57. The tab 57 may include the same material as the collar portion of the carrier 55. Alternatively, the tab 57 may include a different material than the collar portion, such as to optimize bonding or embedding of the indicator 40. The tab 57 may be permanently separated from the capsule 14 by an irreversible operation. For example, the tab 57 may include a frangible portion.

[0140] In other embodiments, no tab 57 is provided and the indicator is mounted to the collar portion of the carrier 55.

[0141] As Figure 10E shown, the sensor 42 is disposed in a suitable position to read the indicator on the carrier 55 / tab 57. The sensor 42 may be positioned as described with reference to Figure 10C In some embodiments, the tab 57 is angled (e.g., away from the edge 34) toward the base 26 of the capsule 14. Thus, when the capsule 14 is within the heating chamber 10, the tab 57 is biased toward the sensor 42. This helps ensure that the indicator 40 can communicate with the sensor 42. The tab 57 is between the edge 34 of the capsule and the edge 52 of the heating chamber. The edge 34 of the capsule may engage the tab 57 and / or bias the tab 57 into engagement with the edge 52 of the heating chamber.

[0142] Figure 10FAnother embodiment of the carrier 55 is shown. The carrier 55 is configured to engage the edge / flange 34 of the capsule 14. The carrier 55 may include a recess / groove configured to receive the edge 34. The carrier 55 may include a snap fit or interference fit with the edge 34. The indicator 40 is mounted on a carrier or insert 59, which is configured to be received within the carrier. The carrier 59 is received within a slot or recess in the tab 57. Thus, the carrier 59 can be inserted into the tab 57. The indicator 40 may be bonded or otherwise secured to the carrier 59. In other embodiments, the indicator 40 may be loosely held on the carrier 59. For example, the indicator 40 may be received within a recess in the carrier 59.

[0143] The carrier 59 can be sealed to the carrier 55 or otherwise permanently fixed to the carrier 55. This helps prevent unauthorized tampering of the indicator 40. The carrier 59 can be adhered to the tab 57 and / or welded / fused to the tab 57. In other embodiments, the carrier can be held via a latch or the like.

[0144] In some embodiments, the thickness of the tab 57 is less than or equal to 1 mm. The tab 57 can thus form a label and / or be flexible. This ensures a close fit between the capsule 14 and the heating chamber 10. Additionally or alternatively, a recess in the edge 52 of the heating chamber is provided to receive the tab 57.

[0145] Generally, it can be seen that the device 2 is configured to communicate with the capsule 14 when the capsule 14 is inserted / accommodated / received within the heating chamber 10. This ensures that the device 2 communicates with the capsule 14 configured to be heated. In an alternative embodiment, the device 2 can be configured to communicate with the capsule 14 not disposed within the heating chamber 10 (i.e., when the capsule 14 is outside the device 2). The sensor 42 can be provided on an external portion of the device 2 / adjacent to the external portion of the device 2. For example, the sensor 42 can be provided on the external portion of the electronic device housing 6 and / or the cover 12. Alternatively, the sensor 42 is positioned such that the capsule 14 can wirelessly communicate with it when it is outside the device 2. The user can then bring the sensor 42 into contact with the capsule 14 and / or bring the capsule 14 within its wireless range to initiate communication therebetween.

[0146] In Figure 11 The indicator 40 is shown in detail. The indicator 40 includes a substrate 54. The substrate 54 may include a polymer or plastic. The substrate 54 can be flexible / bendable. This allows the indicator 40 to be mounted on a non-planar side of the capsule 14 (e.g., the side wall 28). The substrate may include an adhesive or the like to provide attachment to the capsule 14 (e.g., to provide a sticker or label). The indicator 40 can be attached after / during the manufacturing process of the capsule 14.

[0147] The memory device 56 is disposed on the substrate 54 and / or otherwise coupled to the substrate 54. A plurality of contacts 58 are provided for contacting the sensor 42. Any number of contacts 58 may be provided. The contacts 58 are operatively connected to the memory device 56 (e.g., via lines / wires).

[0148] The wireless indicator 40 is shown in Figure 12 . The wireless indicator 40 may be substantially the same as the contact indicator 40, however, an antenna 60 is provided in place of the contacts 58. The antenna 60 is generally in a coiled form. For example, the antenna may be maze-like; spiral / concentric; wavy; and / or branched.

[0149] In embodiments where the indicator 40 is disposed on the edge 34, the antenna 60 may extend completely and / or partially around the perimeter of the edge 34. For example, the antenna may be disposed concentrically / spirally around the edge 34. This allows the indicator 40 to be read in any of its orientations. The antenna 60 and / or the memory 56 may be mounted to the edge 34 or embedded within the edge 34.

[0150] In some embodiments, the indicator 40 may be configured to be optically read by the sensor 42. The indicator 40 thus includes a passive (i.e., non-electric) marker. The indicator 40 thus includes a visual indicator. The indicator 40 may be printed or otherwise deposited onto the capsule 14. The indicator may be disposed on a substrate (e.g., sticker / label) and / or may be directly printed / deposited onto the capsule 14.

[0151] The sensor 42 includes an optical sensor such as a photodiode or a CCD array (e.g., a camera), etc. The sensor 42 may include a light source to illuminate the indicator 40. For example, the light source may include a scanning laser and / or a static light source (e.g., an LED). The sensor 42 includes an image processing system and / or is operatively connected to an image processing system. The image processing system decodes the visual indicator 40 to extract / determine the data contained within the indicator 40. The image processing system thus converts the visual indicator 40 into machine-readable data / code.

[0152] In Figure 13 the illustrated embodiment, the indicator 40 includes a two-dimensional or matrix code. The code may include a QR code. The code may provide a binary code (i.e., the printed portions indicate 1 or 0).

[0153] In Figure 14 the illustrated embodiment, the indicator 40 includes a bar code. The bar code may include any suitable form. Human-readable characters may be provided with the bar code (e.g., to allow the bar code to be read via optical character recognition).

[0154] In Figure 15In the illustrated embodiment, the indicator 40 includes a color code. The color of the color code (e.g., wavelength / RGB) can be determined by the sensor 42, thereby providing data to the device. The color can be pre-associated with a specific instruction, code, product, etc. For example, a specific first smoking product formulation is associated with a first color, a specific second smoking product formulation is associated with a second color, and so on. Alternatively, a specific color is associated with a specific coded entity (e.g., letters, numbers, characters, strings, etc.). The color of the indicator 40 can thus provide a pseudo code. For example, the RGB value of the indicator 40 can be determined. The RGB value can be associated with specific data in the database on the device 2. The system then retrieves the specific data based on the observed RGB value.

[0155] Depending on the sensitivity of the system, the indicator 40 can include any number of predetermined colors. For example, the device 2 can be configured to detect 5 and 100 different / discrete colors.

[0156] In some embodiments, multiple colored indicators 40a - 40c can be used. This provides an N-based coding system (where N is the number of discrete colors). For example, if 10 discrete colors can be detected, then Figure 15 the indicator 40 shown in can encode 1000 discrete variations. This allows for the encoding of strings, etc. and / or a greater number of variations. Although Figure 15 three indicators 40a - 40c are shown in, it can be understood that any number of indicators can be used.

[0157] In some embodiments, the coding can be determined by the intensity (e.g., brightness / darkness) of the indicator 40. In some embodiments, the coding can be determined by the shade / hatch of the indicator. In some embodiments, the coding can be determined by the opacity / transparency of the indicator. In some embodiments, the coding can be determined by the shape, size, relative position / spacing, and / or orientation of one or more indicators.

[0158] It can be understood that the indicator 40 can include any suitable human and / or machine-readable code. For example, the code can be directly set on the capsule 14. The code can include binary, alphanumeric, and / or symbolic codes. The code can include multiple dots or marks. The spatial position and / or orientation of the dots / marks can define the code. The code can include human-readable code. For example, the smoking formulation can be printed on the capsule (e.g., "strawberry flavor"). The image processing system can include a character / image recognition system (e.g., OCR) to read / determine the code. The image processing system can then execute, transcribe, and / or process the code accordingly. This arrangement allows for the use of any suitable code, thereby providing a flexible configuration. The device 2 can be updated / reconfigured to recognize any new code, variable, or configuration.

[0159] In some embodiments, the capsule 14 can be shaped and / or deformed to provide an indicator 40. The capsule 14 can include recesses, protrusions, ridges, and / or notches to provide a code. For example, a QR code or bar code can be embossed / debossed on the surface of the capsule. In other examples, multiple protrusions / recesses can provide an encoded string.

[0160] In some embodiments, the indicator 40 can be detached or removed from the capsule 14. For example, the indicator 40 can include a detachable label or marker. The indicator 40 can be peeled from the capsule 14. The indicator 40 can include a weakened line (e.g., a perforation) to allow detachment from the capsule 14. The indicator 40 can be disposed on one or more removable seals 32.

[0161] In some embodiments, the indicator 40 is separated from or removed from the capsule 14. The indicator 40 can be disposed on a separate label, card, marker, or other substrate. The indicator 40 can be held loosely with the capsule 14. For example, the indicator 40 and the capsule 14 are held loosely within a package or wrapper that contains the indicator 40 and the capsule 14. The indicator 40 can be attached to the capsule 14 via a line, string, adhesive, etc.

[0162] In some embodiments, the indicator 40 is configured to change in response to the use of the capsule 14. The indicator 40 can be configured to change in response to the capsule 14 being exposed to heat. This provides an indication that the capsule 14 has been previously used and / or that the capsule 14 may have been exposed to an undesirable temperature during its transportation and / or storage. Thus, the indicator 40 provides an indication that the capsule 14 may provide a sub-optimal smoking experience. The sensor 32 can include a lighting device that illuminates the indicator 40.

[0163] The indicator 40 includes a thermochromic material. The material thus changes its visual appearance during exposure to an elevated temperature (i.e., above ambient temperature). The material can include pigments, etc. The pigment is incorporated into an ink. The ink is deposited / printed onto the capsule 14. The exact form of such thermochromic materials is not relevant to the present invention, and suitable formulations or components are known to those of ordinary skill in the art. The thermochromic material can include one or more of the following: liquid crystals; leuco dyes; metal oxides; and / or metal complexes.

[0164] In the present embodiment, the thermochromic indicator 40 is disposed on the upper surface 24 and / or the edge 34 of the capsule (e.g., the capsule closure). The sensor 42 is correspondingly disposed on / in the lid 12 of the device 2. The sensor 42 provides a line of sight to the indicator. Thus, the sensor 42 is disposed on the underside of the lid 12 (e.g., as Figure 9 shown). The sensor 42 includes a suitable optical sensor (e.g., a CCD or a photodiode) to detect the thermochromic change of the indicator 40.

[0165] The indicator 40 can be disposed on the upper seal 32. Thus, as Figure 17 shown, when the seal 32 is removed from the closure 24, the portion of the indicator 40 on the seal 32 is removed. A portion of the indicator 40 is thus removable. Although the seal 32 is removed before use, the indicator 40 thereon can still indicate that the capsule 14 has been exposed to elevated temperatures during storage / transportation. When the seal 32 is removed, the indicator 40 is disposed only around the edge 34 of the capsule 14. In other embodiments, the indicator 40 can be applied only to the edge 34 (e.g., to avoid wasting indicator material).

[0166] The indicator 40 is annular or ring-shaped. The ring is substantially continuous. The indicator 40 is disposed around the circumference of the capsule 14 at the same or similar radial distance from the center 62 of the capsule 14 (i.e., the indicator 40 is rotationally self-similar). This ensures that the indicator can be read when the capsule is in any orientation in the heating chamber 10.

[0167] In some embodiments, the capsule 14 can include one or more discrete portions of the indicator 40. In the case where the capsule 14 includes N-fold symmetry, at least N portions of the indicator 40 can be provided. For example, a capsule 14 having 1-fold symmetry requires only a single indicator portion 40 since the capsule 14 can be inserted in only a single direction.

[0168] It will be appreciated that the indicator 40 can include any shape, size, or form. The indicator 40 can include a dot or a patch. The indicator 40 can be applied directly to the capsule 14. The indicator can be applied to a label, sticker, or removable substrate. The indicator 40 can be disposed in any suitable location (e.g., the lower wall 26 or the side wall 28). The sensor can accordingly be disposed in the side wall / lower wall of the heating chamber 10.

[0169] As Figure 18 shown, when heat is applied to the capsule 14 (i.e., when its temperature changes), the indicator 40 is configured to change color. In some embodiments, the indicator 40 can vary the wavelength and / or spectrum of the light emitted by the indicator 40 in response to a temperature change. For example, the indicator 40 can change from blue to red, from white to green, from black to white, etc.

[0170] In some embodiments, the intensity of the emitted light (i.e., the brightness) can vary in response to a change in temperature. For example, at a first temperature, the indicator 40 can be bright, and at a second temperature, the indicator 40 is dark. This can be provided by a change in the reflectivity and / or fluorescence of the pigment.

[0171] In some embodiments, the opacity / translucency of indicator 40 can be configured to vary in response to temperature changes. For example, at a first temperature, indicator 40 is transparent / translucent, and at a second temperature, indicator 40 is opaque. In a particular embodiment, indicator 40 is configured to be transparent / translucent at ambient temperature (i.e., less than 40 °C). The opacity of indicator 40 can increase as the temperature rises. Thus, indicator 40 is generally invisible to the user under ambient conditions. In an alternative particular embodiment, indicator 40 is configured to be opaque at ambient temperature (i.e., less than 40 °C). The opacity of indicator 40 can decrease as the temperature rises.

[0172] A colored portion can be disposed below indicator 40. Thus, when the opacity of indicator 40 changes, an apparent color change of indicator 40 is observed. In some embodiments, the colored portion can include the color of capsule 14 (e.g., its natural color or a coating thereon). Alternatively, the colored portion can be placed within capsule 14 and indicator 40 placed thereon.

[0173] In some embodiments, indicator 40 can be configured to emit radiation in the form of non-visible spectra (e.g., infrared / UV) that are invisible to the naked eye. Indicator 40 can emit non-visible radiation at ambient temperature and / or during temperature changes. Thus, indicator 40 is invisible or does not change significantly during heating of capsule 14. Alternatively, indicator 40 can emit visible light only during a temperature increase. Thus, indicator 40 can be visible only after heating.

[0174] In some embodiments, indicator 40 can be configured to emit radiation only in response to non-visible radiation incident thereon. For example, indicator 40 can be fluorescent. Indicator 40 can fluoresce in response to UV light. Thus, in the absence of UV light, the indicator may be invisible and / or may not emit light.

[0175] In the case where indicator 40 responds to / emits non-visible radiation, sensor 42 can be configured to detect non-visible radiation and / or the lighting device can be configured to emit non-visible radiation accordingly. The sensor can include a UV / IR sensor and the lighting device can include a UV / IR source (e.g., a UV / IR diode).

[0176] It will be appreciated that sensor 42 is configured to detect changes in the wavelength, intensity, and / or spectrum of the radiation emitted by indicator 40. Thus, a "color change" can be interpreted as a corresponding change in the wavelength, intensity, and / or spectrum of the radiation emitted by indicator 40.

[0177] In some embodiments, the indicator 40 is configured to gradually change color (the color change is continuous) as the temperature changes. This may allow a user to determine the temperature to which the capsule 14 has been exposed. For example, the user may be able to compare the color of the indicator 40 with a calibration chart to determine the temperature to which the capsule 14 has been exposed. In some embodiments, this may allow the device 2 to determine the current temperature of the capsule 14. This may provide feedback to the device 2, for example, to ensure that the device 2 is operating at the correct temperature. Alternatively, this may allow a visual inspection of the capsule 14 to allow for manual adjustment of the temperature, etc.

[0178] In some embodiments, the indicator 40 is configured to gradually change color as the temperature changes (i.e., the color change is discrete / discontinuous). The indicator 40 may be configured to change color at a predetermined temperature. The predetermined temperature may be a temperature at which an irreversible change may occur in the smoking product, thereby providing a sub-optimal smoking experience. Two or more predetermined temperatures may be set. Accordingly, two or more discrete color changes may be provided. For example, a first color change may indicate that the capsule 14 has been stored / transported at a temperature above a first predetermined temperature. The first predetermined temperature may be about 60 °C. A second color change may indicate that the capsule 14 has been heated in the device 2 to a temperature above a second predetermined temperature. The second predetermined temperature may be about 100 °C. The indicator 40 may thus indicate that the capsule 14 has been exposed to one or more different temperatures.

[0179] The color change may saturate (i.e., stop changing) at a predetermined temperature. This temperature may be determined based on the desired operating parameters of the device 2 or the smoking product. For example, the color change may saturate at a temperature greater than or equal to 60 °C, preferably greater than or equal to 100 °C, preferably greater than or equal to 150 °C.

[0180] In some embodiments, the color change of the indicator 40 may be irreversible. Thus, once the indicator 40 has changed from its original color to a new color, the indicator will not return to its original color even if the temperature returns to ambient temperature. This provides a permanent or semi-permanent indication that the capsule 14 has been exposed to an elevated temperature. The indicator 40 may thus provide a tamper-proof indicator 40.

[0181] In other embodiments, the color change of the indicator 40 may be reversible. This may allow the temperature of the capsule 14 to be monitored during heating of the capsule 14 (to provide feedback to the device 2). The monitoring may be provided in real time.

[0182] In some embodiments, the indicator 40 is configured to indicate the freshness of the smoking product 30. The indicator 40 may include a material configured to change color over time (i.e., the color of the indicator is time-dependent). Thus, the color of the indicator 40 can provide an indication of the time since its manufacture. In some embodiments, the indicator 40 changes color in response to exposure to oxygen. This can indicate oxidation of the smoking product 30. In some embodiments, the indicator 40 changes color in response to moisture and / or liquid.

[0183] In some embodiments, the hookah device 2 may read or communicate with the indicator 40 via an intermediate device 64. The intermediate device 64 is separate / different from the hookah device 2. Generally, the intermediate device includes an electronic or computing device, such as: a keychain; a touchscreen device; a button / selector device; a mobile (cellular) phone; a tablet computer; a laptop computer, etc. In some embodiments, the intermediate device may include a dedicated user / sensor interface device for use with the device 2, such as a reader or an NFC device.

[0184] The intermediate device 64 is connected to the device 2 to transmit signals from the intermediate device 64 to the device 2 and / or vice versa. Thus, the intermediate device can transmit data of the indicator 40 and / or data related thereto. In the present embodiment, then, the intermediate device 64 is wirelessly connected to the hookah device 2. Any suitable technology may be used, such as: Wifi, Bluetooth (RTM), NFC, IrDA, etc. The intermediate device 64 and the hookah device 2 each include a wireless communication interface. The intermediate device 64 may include a remote device (i.e., capable of operating at a location separate from the hookah device 2). In other embodiments, the connection between the hookah device 2 and the intermediate device 64 may be wired.

[0185] The hookah device 2 may be connected to the intermediate device 64 via an intermediate server or the like. For example, the device 2 may be connected to the intermediate device 64 via the Internet or via a local area network connection or via a direct connection to the intermediate device 64.

[0186] The intermediate device 64 includes a sensor 66 configured to read / interrogate the indicator 40 on the capsule 14. The sensor 66 may be substantially the same as the previously described sensor 42. In the embodiment shown in FIG. 19, the sensor 66 includes a camera. The camera can capture one or more images of the indicator 40. In other embodiments, the sensor 66 may include an NFC sensor. The NFC sensor can read / interrogate the data on the indicator 40.

[0187] In some embodiments, the intermediate device 64 may transfer data from the indicator 40 to the hookah device 2 only, for example, without modification or with only verification indicators. The intermediate device 64 acts as a pass-through or relay device. The data from the indicator may be interpreted / processed on the hookah device 2. In additional examples, the intermediate device 64 may modify, redact, or supplement the data of the indicator 40 or portions thereof. The intermediate device 64 may be used to implement, for example, user preferences or selections.

[0188] In some embodiments, the intermediate device 64 is configured to interpret / process data from the indicator 40. The intermediate device 64 may extract one or more data portions (e.g., data fields) from the indicator data. Then, the data and / or data portions may be stored in a memory on the intermediate device 64. The intermediate device 64 may include software (e.g., an app) configured to read / extract / process the indicator data.

[0189] The intermediate device preferably provides a user interface. The intermediate device 64 may present information related to the cartridge 14 to the user, for example, on a display. The information may include one or more extracted data portions / fields. For example, as shown in FIG. 19, the intermediate device 14 may indicate to the user the flavor, authenticity, heating temperature / profile, and / or heat exposure indicator. This allows the user to inspect and / or interrogate the cartridge 14 without inserting the cartridge 14 into the hookah device 2.

[0190] The intermediate device 64 may send the indicator data and / or portions thereof to the hookah device 2. The data sent to the hookah device 4 may include all of the data or the extracted fields. Alternatively, the intermediate device 64 is configured to transfer only a portion of the data or the extracted fields to the hookah device 2. In some examples, the selected portion of the data / fields is predetermined based on the operating parameters of the hookah device 2. For example, the hookah device 2 may be able to operate effectively only if the heating temperature / profile is transferred to it.

[0191] In embodiments having the intermediate device 64, the hookah device 2 may further be configured to read the indicator 40, as described above. Thus, the intermediate device 64 may be used in conjunction with the hookah device 2, for example, to verify only the contents of the cartridge 14 before use or to modify the data read directly by the device from the indicator 40.

[0192] In some embodiments, the intermediate device 64 is configured to provide two-way communication with the hookah device 2. The hookah device 2 can thus send data to the intermediate device 64. The hookah device 2 can send indicator data and / or portions thereof to the intermediate device 64. The intermediate device 64 can display the indicator data and / or portions thereof. The hookah device 2 can send operation / heating information to the intermediate device 64. For example, the hookah device 2 can send sensor data (e.g., the temperature of the heater 10) to the intermediate device 64. The hookah device 2 can send status updates and / or error messages to the intermediate device 64. Thus, the intermediate device 64 can operate as an external display for the hookah device 64.

[0193] In one usage example, the cartridge indicator data can include multiple different heating profiles for the cartridge, and the intermediate device can be used to select one of the heating profiles for the device 2 to implement. The profiles can include, for example, mild, normal, and aggressive heating profiles for a single user, or different smoking session durations. The profiles can include a 'group' or 'party' mode, whereby the device is intended for use by a number of users, which requires a different heating profile than for a single user.

[0194] Figure 19B The use of the intermediate device 64 is shown, which is configured to communicate directly with the indicator 40 (i.e., transmit data to it). The intermediate device 64 may not communicate directly with the device 2. The intermediate device can write to or modify data on the indicator 40. This can allow for the customization / optimization of the date or instructions provided on the cartridge 12 (e.g., heating profile, operation time, or pause time). Additionally or alternatively, the data transmitted from the intermediate device 64 to the indicator 40 can be further transmitted to the hookah device (e.g., when the cartridge is inserted therein). This can allow for the upgrading or enhancement of the functionality of the device 2 without the need for the device 2 to have connectivity to a public network (e.g., the Internet).

[0195] As previously discussed, the indicator 40 can include information / data related to one or more parameters or characteristics of the cartridge 14 and / or the smoking product 30. The indicator 40 can include data related in particular to one or more of the following:

[0196] · One or more flavors of the smoking product 30. This can include broad qualitative indications (e.g., "sweet" or "sour") and / or specific qualitative flavors (e.g., "strawberry flavor" or "bubblegum flavor").

[0197] · One or more components of the smoking product 30. This may include a list of all or some of the components (e.g., active ingredients). The list may include the weight / volume and / or relative proportions of one or more components. One or more allergens may be indicated. The indicator 30 may indicate whether the smoking product 30 contains tobacco and / or a nicotine-containing product.

[0198] · The components or type of the smoking product 30. This may indicate the general form of the smoking product, e.g., whether the smoking product 30 includes tobacco, inert beads, paste, and / or combinations thereof. · The amount of the smoking product 30 (e.g., weight / volume) and / or the size of the capsule 14 (e.g., weight / volume / dimensions).

[0199] · The heating temperature of the smoking product 30. This indicates the preferred or optimal temperature of the smoking product 30 during its heating to ensure an optimal smoking experience.

[0200] · The heating profile and / or power profile of the smoking product 30. This indicates the preferred or optimal temperature curve over time of the smoking product 30 during its heating to ensure an optimal smoking experience. This will be described in detail later.

[0201] · A pause profile to determine the length and / or temperature of a pause event. The pause profile may be user-customizable. The pause profile may determine the length of each smoking session and / or provide a corresponding heating profile when that smoking session resumes.

[0202] · Data related to the manufacture or distribution of the capsule 14. For example, one or more of the following: batch number; manufacturing date / time; quality control mark; manufacturer identifier; supplier identifier; distributor identifier.

[0203] · Data related to the integrity of the smoking product 30, such as the date of use; or expiration date. This may be provided by a heat exposure indicator (e.g., a thermochromic pigment). In some embodiments, the hookah device 2 may write data to the indicator 40 to indicate that the capsule 14 has been heated or used. The indicator 40 may thus include a mark or logo.

[0204] · Data for authenticating the capsule 14. This allows the user to verify that the capsule 14 is genuine. Authentication may include a unique code / password, hash, authentication token, and / or signature. This may be verified against a database of known codes (e.g., a database using an internet connection). In some embodiments, the data may include a self-verifying code / string. For example, the code may include one or more check digits or a checksum.

[0205] · Usage restrictions. This can include age restrictions, e.g., where the smoking product 30 includes tobacco, alcohol, caffeine, or other age-restricted goods. The age restriction can indicate a quantity (e.g., 16, 18, or 21) and / or a quality (e.g., "child", "adult", etc.). In some embodiments, the smoking product 30 and / or the specific capsule 14 can be associated with a specific user or user category. For example, this can be used where the smoking product 30 includes a prescription or other regulated ingredient. The data can include a user ID. The data can include a username and / or

[0206] or a unique code.

[0207] · Checksum. A checksum can be used to verify the data stored on the indicator 40 and / or portions thereof.

[0208] It will be understood that the parameters can be stored as database fields, etc. The hookah device 2 and / or the intermediate device 64 can thus extract and / or process any fields as described previously.

[0209] Figure 20 The heating profile 68 of the capsule 14 and / or the smoking product 14 is shown. The heating profile 68 defines the optimal or preferred heating temperature of the capsule 14 over time. The heating profile 68 can be determined using any suitable method, as will be understood by those skilled in the art. Generally, the heating profile depends on one or more of the following: the type / component of the smoking product 30, the weight / volume of the smoking product 30, and / or the shape / size and / or thickness of the wall of the capsule.

[0210] In some embodiments, for a specific smoking product 30 and / or capsule 14, the heating profile 68 can be fixed or standardized. Thus, the indicator 40 for each capsule 14 containing the product 30 includes substantially the same heating profile data.

[0211] In other embodiments, the heating profile 68 can vary between different capsules 14 containing the same smoking product. This can allow variations in the heating profile 68 to accommodate variations in the manufacture of the smoking product 30, e.g., due to different temperatures, humidities, or starting materials. The smoking product 30 can be sampled periodically and the heating profile 68 determined accordingly. The smoking product 30 can be sampled at predetermined intervals and / or between batches.

[0212] The temperature of the capsule 14 is typically controlled by controlling the temperature of the heater 10. Generally, the heat output of the heater 10 is controlled by varying the electrical power input to the heater 10. Thus, the heating profile 58 can provide a power profile. The hookah device 2 includes a monitoring system for monitoring the temperature of the heater 10 and / or the capsule 14. The monitoring system can include a thermometer operatively connected to or engaged with the heater 10 and / or the capsule 14. The thermometer can include one or more of the following: a thermocouple; an infrared thermometer; a resistance thermometer, etc. In some embodiments, the monitoring system can use a color change of the capsule indicator 40 to indicate its temperature.

[0213] The hookah device 2 can be configured to heat the capsule 14 at a plurality of different temperatures. Thus, the heating profile 68 includes a plurality of different temperatures (i.e., different temperature levels). This provides a plurality of different heating stages. For example, the heating profile 68 includes a first temperature 70 and a subsequent second temperature 72. The heating profile can be maintained at a given temperature for a predetermined period 74. The first temperature 70 is greater than the second temperature 72 to ensure that the smoking product 30 in the capsule 14 uniformly reaches the desired temperature. During this period, the user may not puff on the hookah device 2. This provides an initial "preheat stage". The second temperature 72 can then provide the temperature at which the user inhales the vaporized smoking product 30. This provides a "smoking stage".

[0214] The change between the first temperature 70 and the second temperature 72 can be transient. Thus, the change / boundary between the first temperature 70 and the second temperature 72 is stepped or discontinuous.

[0215] The heating profile 68 can vary continuously over a given period 76. For example, the heating profile 68 can steadily decrease over the period 76. This provides a "ramp down" of the temperature to prevent the combustion depletion of the smoking product 30 (i.e., the temperature is proportional to the remaining mass of the unconsumed smoking product 30)

[0216] In some embodiments, the hookah device 2 is configured to change the temperature of the heater 10 in response to the user's inhalation. Generally, the temperature increases to counteract the cooling effect of the incoming air. Additionally or alternatively, this increases the amount of vapor produced by the smoking product 30 to provide an improved smoking experience. This provides an active means of ensuring the quality of the smoking experience. The increase in temperature can provide an inhalation event 78 within the heating profile 68. Thus, the heating profile 68 only provides a baseline for the temperature of the heater 10 and its temperature can vary according to the user's inhalation.

[0217] The increase in temperature can be at least 5 °C; preferably at least 10 °C; preferably at least 20 °C. Additionally or alternatively, the temperature during the inhalation event 78 can include the absolute temperature. The absolute value can be stored on the indicator 40. The increase in the power of the heater 10 can be at least 3%; preferably at least 5%; preferably at least 10%.

[0218] Inhalation can be detected via an inhalation sensor. The sensor can include a pressure sensor, etc. The pressure sensor can include a resistive, capacitive, and / or inductive pressure sensor. Additionally or alternatively, the sensor includes a mechanical airflow sensor. For example, the sensor can include a flap or diaphragm configured to move during inhalation. The flap / diaphragm can be connected to a potentiometer, etc. Additionally or alternatively, the sensor includes an accelerometer that measures the vibrations in the system caused by inhalation and bubble formation. The sensor can be located in the air passage between the mouthpiece 22 and the intake orifice 17 or at any suitable location outside the air passage. The inhalation sensor is operatively connected to the heater controller to control the power flow to the heater 10.

[0219] In some embodiments, the inhalation event 78 is configured to be activated only during the inhalation period. The increase in the power to the heater 10 is thus provided only during inhalation. In some embodiments, the inhalation event 78 is configured to be activated for a predetermined period of time. Once inhalation is detected, an increase in the power to the heater 10 is thus provided for a predetermined period of time. The predetermined period of time can be started at the beginning or end of the user's inhalation.

[0220] In some embodiments, the inhalation event 78 is configured to attempt to offset only the cooling effect of the incoming air. The heater 10 thus attempts to maintain the temperature of the heating profile 68. The temperature loss during inhalation can be pre-calibrated. For example, if it is observed in a calibration experiment that the temperature drops by 10 °C during inhalation, this value is stored on the device, and then the heater temperature is correspondingly configured to increase by 10 °C when the inhalation event is detected. Thus, the heating profile 68 is maintained. It can be understood that the cooling effect can be proportional to the inhalation rate. The device 2 can be configured to determine the inhaled air flow rate and adjust the temperature increase accordingly. The device 2 thus predicts the temperature decrease of the heater 10 and adjusts the power of the heater 10 to at least partially offset the decrease.

[0221] In some embodiments, the heater 10 is configured to be regulated reactively in response to the user's inhalation. The device 2 can thus monitor the temperature of the heater 10. If the temperature drops during heating, the power to the heater is increased. Thus, the heater 10 attempts to track the temperature of the heating profile 68. Although this arrangement does not require the use of an inhalation sensor, the smoking experience may not be sub-optimal.

[0222] The heating profile 68 can include any number of heating temperatures / levels. One or more temperatures can be repeated in the heating profile. Thus, the heating profile 68 can be cyclic / wavy. The time period 74 at each temperature can vary between multiple temperatures. The boundary / ramp can include any suitable gradient. The gradient can vary between different temperature boundaries / ramps. The heating profile 68 can vary continuously and / or discontinuously. The heating profile 68 can be curved and / or include linear portions.

[0223] In a first embodiment, the general form (i.e., shape) of the heating profile 68 is stored on the hookah device 2. The hookah device 2 can store one or more heating profiles 68. The indicator 40 is configured to contain data configured to modify the pre-stored / pre-defined heating profile 68.

[0224] As Figure 21 shown, in some embodiments, the indicator data includes modifiers configured to modify the temperature values, power values, and / or time values of the heating profile 68. For example, in the heating profile 68A, the modifier changes the temperature or power of the heating profile 68. The modifier can include a simple scalar modifier (e.g., the heating profile 68 is multiplied by a scalar value). In this example, the scalar modifier is greater than 1, thereby increasing the temperature or power of the heating profile 68. Since the modifier is a simple scalar modifier, the temperature / power across the entire heating profile 68A is modified. Such an arrangement provides a simple variation of the heating profile 68 to accommodate the temperature requirements of the smoking product 30. A low-temperature smoking product 30 can have a relatively low modifier value, and vice versa.

[0225] In the heating profile 68B, the modifier changes the total time period 80 of the profile 68. The modifier can include a simple scalar modifier. Such an arrangement provides a simple variation of the heating profile 68 to accommodate the quantity / size of the smoking product 30 and / or the capsule 14. A relatively low weight / volume of the smoking product 30 can have a relatively low modifier value, and vice versa.

[0226] In some embodiments, the modifier is configured to modify only a selected portion of the heating profile. The modifier can modify only the temperature / time period 74 of a selected portion of the temperature levels. For example, the modifier can modify only the temperature and / or time period 74 of the preheating phase and / or the smoking phase.

[0227] In some embodiments, the modifier can be configured to provide temperature and / or time period data for each phase. Thus, while the general form of the heating profile remains constant, the time period and temperature of each phase can be changed independently. When the capsule indicator 40 is read, the modifier can be automatically applied by the device 2 or manually selected by the user, e.g., using the intermediate device 64.

[0228] In some embodiments, multiple different heating profiles 68 may be stored on the device 2. The indicator 40 may thus include an indication of the specific heating profile 68 desired. Accordingly, a specific heating profile 68 is selected based on the inserted capsule 14 and / or the smoking product 30. This allows for multiple different heating profiles to be provided while maintaining a minimum amount of data on the indicator 40.

[0229] Figure 22 An example of the data structure on the indicator 40 is shown. The data includes an identifier 82 related to the smoking product 30 and / or the capsule 14. The hookah device 2 can read / interpret the identifier 82 to identify the smoking product 30 / capsule 14 accordingly. The data includes a heating profile indicator 84 configured to indicate a specific heating profile 68 pre-recorded on the hookah device 2. Thus, when the hookah device reads the data, the heating profile 68 is selected accordingly. At the same time, Figure 22 while the data only includes temperature and time, actual examples of the present invention may also include power settings for the device / heater.

[0230] In some embodiments, the product / capsule identifier 82 may be associated with a specific heating profile 68 in the memory of the hookah device. Thus, the hookah device 2 automatically selects the heating profile based on the product / capsule identifier 82.

[0231] In some embodiments, the pre-recorded heating profile 68 may be manually selected by the user. For example, the capsule 14 and / or the associated packaging may include printed instructions for the user. The user may manually select the heating profile via a manual input (such as a button or a dial, etc.) on the hookah device 2 and / or may use an intermediate device 64.

[0232] The data may include a phase identifier 86. This identifies and / or depicts different phases (such as different temperature or power levels). The data includes a temperature indicator 88 to indicate the desired temperature for each phase. The temperature indicator 88 may indicate a fixed temperature and / or a temperature gradient (such as the temperature change per unit time). The data includes a time interval indicator 90 to indicate the desired time interval / cycle for each phase. The data may then accordingly include temperature and time period data for each phase. The hookah device 2 can thus read the data for each phase and construct the heating profile 68. It can be understood that instead of providing temperature or time period values, temperature and / or time period modifiers may be provided.

[0233] Referring to Figure 23 , in some embodiments, the optimal / preferred heating profile 68 may be sampled at multiple points 92. As Figure 24As shown, the sampling point 92 can be stored on the indicator 40. The sampling point 92 includes a temperature and / or power indicator 96. The sampling point 92 includes a time indicator 98 corresponding to the temperature and / or power indicator 92. Thus, the sampling point 92 provides coordinates and the like.

[0234] As Figure 25A and Figure 25B shown in, the sampling point can be processed by the hookah device 2 to provide a reconstructed heating profile 94. Providing specific data points or coordinates on the capsule indicator 30 allows the hookah device 2 to operate using only the input from the capsule 14. This reduces the need to store any pre-programmed profiles and the like on the device 2. The device 2 can thus accept any suitably formatted profile with any level of complexity. This provides a forward-looking arrangement as the heating profile can be changed or generated during the capsule manufacturing / programming phase without the need to modify / update the device 2. The hookah device 2 can thus include a "dumb" device into which only the heating profile instructions are inserted.

[0235] In Figure 25A the embodiment shown, the hookah device 2 is configured to interpolate and / or extrapolate between multiple sampling points 98. This provides a continuous heating profile 68. Thus, the heating profile can include a heating gradient. In Figure 25B the embodiment shown, the hookah device 2 can change the indicated temperature 96 at the indicated time 98 only in a stepwise manner. The temperature in each stage remains substantially constant. Thus, the sampling point 92 can provide boundary points for multiple stages.

[0236] The power setting for each stage can include the maximum / threshold power for that stage or a substantially constant power.

[0237] In this embodiment, the sampling point 92 is set only at the boundaries between different stages of the heating profile. Thus, the sampling point 92 is set only at the points where the heating profile 68 changes gradient (e.g., turning points or inflection points) and / or at the points where the heating profile 68 changes in a stepwise manner. This provides a minimum number of sampling points while generally providing an accurate / representative heating profile 68.

[0238] In some embodiments, the sampling point 92 is set at a predetermined time interval. For example, the sampling point 92 can be set at a fixed interval. This can be beneficial in cases where the heating profile 68 is complex. In the case of setting the sampling point at a fixed interval, the time indicator 98 does not need to be set in the indicator data as the fixed interval can be pre-programmed into the hookah device 2. Additionally or alternatively, the indicator data can specify the fixed time interval and the hookah device 2 constructs the heating profile accordingly.

[0239] As Figure 26As shown, the heating profile 68 can be smooth. This provides a continuous and / or step-free heating profile 68. This can be achieved by applying a smoothing algorithm to the heating profile 68. Then, the heater 10 heats the capsule 14 according to the smoothed heating profile. Additionally or alternatively, the heater 10 can be configured to heat the capsule 14 in a smooth manner regardless of the heating profile 68. For example, a PID controller can be used to control the heater 10. This prevents exceeding the desired temperature / or fluctuations around the desired temperature, etc.

[0240] It can be understood that the heating profile 68 only provides the desired heating temperature. In practice, the actual temperature achieved can vary for a variety of reasons, such as: thermal lag; feedback / sensor lag; user inhalation; air temperature; and / or other unexpected thermal variations. Thus, the heater 10 is configured to continuously adapt its temperature to achieve the specified heating profile 68. The actual temperature can oscillate around and / or towards the desired temperature.

[0241] In some embodiments, the indicator 40 can include multiple heating profiles 68. The heating profile 68 can be modified according to one or more usage scenarios. For example, a user may want a "strong" smoking experience. Thus, the heating profile can operate at a higher temperature during one or more of its stages. Conversely, a user may require a "mild" experience, where the heating temperature is relatively low. Alternatively, the user can specify the number of users for a smoking session. Thus, the heating profile can operate at a higher temperature to accommodate the increased amount of smoke required for the increased number of users. The user can use the intermediate device 64 as described above to select any such modification. It can be understood that the heating profile can vary according to one or more of the following:

[0242] · Smoke intensity;

[0243] · Smoking time;

[0244] · Number of users;

[0245] · The number of pauses permitted during a smoking session, the time permitted for each respective pause, or the total pause time;

[0246]

[0247] · The indication of the capsules used during a multi-capsule smoking session (i.e., when stacked as previously discussed) or a combination thereof.

[0248] The duration, power, and / or temperature of each stage of the heating profile and / or the aspiration temperature can vary according to usage. The overall shape (i.e., the relative temperature of each stage) can vary according to usage. A limited number of heating profiles 68 can be provided based on discrete user selections. For example, the user can select "high", "medium", or "low". Additionally, the heating profile can vary according to any scale. For example, the user selects a value between 1 and 10.

[0249] It will be appreciated that the heating profiles 68 and / or the corresponding time / temperature values provided above and in the figures are arbitrary and are only used to illustrate the present invention. The heating profiles 68 and the corresponding data can be presented or recorded in any suitable form.

[0250] In the above embodiment, the parameters related to the capsule 14 and / or the smoking product 30 are stored on the indicator 40. Then, the hookah device 2 reads / queries the indicator 40 and processes the parameters accordingly. Figure 27 Such an arrangement is schematically shown in. It can be seen that the capsule / product parameters 100 are read / queried by the hardware / software 102 on the hookah device 2. The hardware / software 102 can include programmable logic (e.g., FPGA) and / or firmware, etc. The hardware / software generally includes "low-level" systems / languages. Then, the parameters 100 are processed by the executable code 104 located on the hardware / software 102. The executable code 104 is stored in the memory of the hookah device 2. The executable code 104 generally includes "high-level" systems / languages. The executable code 104 can process the parameters 100.

[0251] The executable code 104 and / or the device software 102 (e.g., firmware) can be variable and / or replaceable (i.e., the memory is rewritable). This allows the hookah device 2 to be updated, for example, to provide additional or different heating profiles, etc. The hookah device 2 can be Internet connectable and / or configured to receive code updates from an intermediate device 64.

[0252] In Figure 28 In the alternative embodiment shown, the executable code 104 is configured to be stored on the indicator 40. The indicator 40 thus includes high-level executable code. The hookah device 2 is configured to read / query the indicator 40 and extract the executable code 104 therefrom. The executable code 104 can be stored in the memory of the hookah device 2. The executable code 104 can then be executed by the hookah device 2. The parameters 100 can be extracted from the indicator 40 and processed by the executable code 104.

[0253] The executable code 104 is stored on the indicator 40 such that the executable code 104 can be accessed from an external device. For example, the executable code 104 is stored in a portion of the memory that is accessible from an external device. Additionally or alternatively, the indicator 40 can be configured to transmit the executable code when queried (e.g., where the indicator 40 is an NFC device). The code can include open / plain text or be encrypted.

[0254] The executable code 104 can be stored on the hookah device 2 in a permanent or persistent manner. This allows the hookah device 2 to be updated with new executable code.

[0255] In some embodiments, the executable code 104 can be stored on the hookah device 2 in a semi-permanent or temporary manner. For example, the replaceable executable code 104 can be replaced when the hookah device 2 reads / queries a new indicator. Thus, the executable code 104 can be customized for the corresponding capsule 14 and / or smoking product 30. For example, this can allow for customization of the heating profile 68. Additionally or alternatively, this can allow the hookah device 2 to provide functions that were not previously possible with the existing executable code 104.

[0256] In some embodiments, the executable code 104 can be removed after a predetermined period of time. In some embodiments, the execution code 104 can be removed once power to the hookah device is removed (e.g., the executable code can be stored in non-volatile RAM). In some embodiments, the execution code 104 can be removed in response to completion of a heating cycle and / or removal of the capsule 14 from the hookah device 2.

[0257] In some embodiments, if the executable code 104 is not provided (e.g., the code 104 has been erased), then the hookah device 2 is configured to be inoperative. For example, the hookah device 2 can refrain from activating the heater 10. This prevents unauthorized use or tampering with the hookah device 2. For example, this can prevent the hookah device 2 from operating with a capsule 14 inserted. Without the executable code 104 provided, the hookah device 2 generally includes only a low-level system. Such a low-level system can provide only basic functions, such as providing a read / query of the indicator 40. The hookah device 2 can provide a "dumb" system. Thus, the system can listen / wait for instructions from the indicator 40 on the capsule 14 and / or via the intermediate device 64.

[0258] Reference will be made to Figure 29Describes an operating method of a hookah device. In an initial step 106, the capsule 14 is inserted into the hookah device 2. The capsule 14 is placed within the heating chamber 10. The capsule 14 provides a close fit within the heating chamber 10 to ensure good thermal contact with the heating chamber 10. Then the lid 12 is closed over the capsule 14 to enclose the capsule within the heating chamber 10. The lid 12 may engage and / or seal the capsule 14. Power may be provided to the hookah device 2 before and / or after inserting the capsule.

[0259] In the next step 108, the hookah device 2 reads / queries the indicator 40. As previously described, the hookah device 2 extracts and / or processes the data on the indicator 40. This may be performed directly by the hookah device 2 and / or via an intermediate device 64. The hookah device 2 may be configured to periodically attempt to read / query / check the indicator 40 to detect its presence.

[0260] In some embodiments, the hookah device 2 is configured to transmit an authentication code / token to the indicator 40. The indicator 40 then interprets the authentication code to determine if the code is genuine. If the code is considered to be genuine / valid, the indicator 40 may initiate and / or permit further communication with the hookah device (i.e., transmit the data thereon). If the code is not considered to be genuine / valid, further communication is blocked. Then, communication may be blocked until the hookah device 2 transmits a valid authentication code. This prevents unauthorized probing or extraction of data from the indicator 40, thus ensuring its integrity.

[0261] The authentication code may take any suitable form and / or use any suitable technology, as previously described with reference to the capsule authentication code. The authentication code may include an Advanced Encryption Standard (AES) code / cipher.

[0262] In the next step 110, the hookah device 2 verifies the integrity of the capsule 14 and / or the smoking product 30. This may take various forms, such as one or more of the following:

[0263] · Verifying the authentication code / signature. The hookah device 2 includes an algorithm for processing the authentication code to determine if the code is genuine. The algorithm may include a hashing algorithm. The hookah device 2 may be configured to provide a time delay between providing the respective verification processes. For example, in a case where a capsule 14 is inserted into the hookah device 2, verified, removed and then a second capsule 14 is inserted, the second verification process for the second capsule 14 will only be initiated after a time delay. The time delay may be greater than or equal to 0.1 s; preferably greater than or equal to; preferably greater than or equal to 1 s; preferably greater than or equal to 2 s. This may help prevent reverse engineering of the verification code via brute force attacks. In some embodiments, the delay may be greater than or equal to 30 seconds.

[0264] · Determine whether the capsule 14 has been exposed to an undesirable temperature. For example, by determining the color of the thermochromic indicator.

[0265] · Determine whether the smoking product is within / outside its expiration date.

[0266] · Determine that the capsule 14 is correctly positioned within the heating chamber 10 (e.g., whether the indicator 40 is correctly readable / queryable).

[0267] · Determine that the type / size / weight of the smoking product 30 is suitable for use with the hookah device 2.

[0268] · Determine whether usage restrictions are met. The hookah device 2 and / or the intermediate device 64 may include a record of user credentials. For example, a user profile is stored on the hookah device 2 and / or the intermediate device 64. The system verifies whether the user's age and / or ID match the credentials on the user profile.

[0269] · Verify the data checksum. If the checksum fails, then read /

[0270] query the indicator 40 again.

[0271] In the case where the hookah device 2 determines that the capsule 14 and / or the smoking product 30 do not meet the required integrity and / or restriction parameters, the hookah device 2 may initiate an end routine 112. In the end routine 112, the hookah device 2 prevents any heating of the capsule 14 (i.e., does not activate the heater 10). A notification may be provided to indicate the reason for the failure to meet the integrity parameters. For example, an "AUTHENTICATION FAILED" or "CAPSULE PREVIOUSLY HEATED" message may be provided. The notification may be provided as an error code or the like. The notification may be provided by a visual indicator (e.g., an LED or a visual display) on the hookah device 2. The notification may be provided directly on the hookah device 2 and / or via the intermediate device 4.

[0272] In the next step 114, the hookah device 2 is configured to eject the capsule 14. This may occur automatically or manually. The hookah device 2 includes an ejection mechanism, and the ejection mechanism is correspondingly configured to eject the capsule 14 from the heating chamber 10. The lid 12 may be configured to open as part of a capsule ejection portion (e.g., the lid 12 and the ejection mechanism may be operably connected via a linkage or the like). Additionally or alternatively, a notification is provided to the user to manually remove the capsule 14.

[0273] It can be understood that the above verification step 110 may be performed by the intermediate device 64. The intermediate device 64 may send a signal to the hookah device 2 to indicate whether the integrity check is successful and / or unsuccessful.

[0274] In the case where the hookah device 2 determines that the capsule 14 and / or the smoking product 30 do not meet the required integrity parameters, the hookah device 2 can prevent the start of the heating profile loading step 116. The heating profile 68 is extracted and processed from the data on the indicator 40. The heating profile 68 can be loaded into the memory on the hookah device 2.

[0275] In embodiments where a thermochromic indicator 40 is provided, an initial heating step 118 can be provided. This initial step heats the capsule 14 to a predetermined temperature. Generally, the predetermined temperature is greater than or equal to the maximum temperature at which the smoking product 30 maintains its integrity (i.e., the temperature that irreversibly harms the smoking product 30). The predetermined temperature is generally less than the heating profile temperature to prevent any potential undesirable exhaust gases from non-genuine products. The predetermined temperature can be greater than or equal to 50 °C, preferably greater than or equal to 60 °C. The predetermined temperature can be less than or equal to 120 °C, preferably less than or equal to 100 °C. The capsule 14 can be heated at the predetermined temperature for a predetermined period of time. The predetermined period of time can be between 1 minute and 10 minutes, preferably between 2 minutes and 8 minutes.

[0276] In the next step 120, the color of the thermochromic indicator is determined during and / or after the heating step 118. The hookah device 2 determines the change in color (or lack of color). The color change can determine whether the capsule has been previously exposed. For example, if no color change is measured, then during transportation / storage, the capsule 14 may have been exposed to excessive heating. If the capsule 14 is considered to have been exposed to excessive heating, then the hookah device 2 can start the end routine 112. The hookah device 2 can provide a notification accordingly.

[0277] If the capsule 14 is considered not to have been exposed to excessive heating and / or in embodiments where no thermochromic indicator is provided, then the hookah device 2 can start the heating step 122. In step 122, the heater 10 heats the capsule according to the predetermined heating profile 68. Then, the user can inhale / smoke the smoking product 30 as needed.

[0278] During the heating step 122, the hookah device 2 is configured to monitor a "pause" event 124. The pause event 124 is configured to indicate that the user desires to pause the use of the device for a period of time. During the pause event 124, the heater 10 can reduce its temperature. Accordingly, the electric power to the heater 10 can be reduced. In some embodiments, the temperature can be only partially reduced. For example, if the heater is configured to operate under normal conditions at 180 °C, then during the pause event, the heater 10 can operate at 100 °C. The pause temperature can be less than or equal to 80% of the normal temperature; preferably less than or equal to 60% of the normal temperature; preferably less than or equal to 50% of the normal temperature.

[0279] In other embodiments, the temperature is reduced to ambient temperature. Thus, the electrical power to heater 10 can be zero. This can prevent overburning of the smoking product 30.

[0280] When a pause event 124 is detected, the temperature of heater 10 is reduced. The pause event can continue until a "resume" event 126 is triggered. The resume event 126 instructs the hookah device 2 to continue heating the capsule 14 according to the heating profile 68. Thus, the pause event 124 can continue for an indefinite period of time.

[0281] In some embodiments, the pause event 124 can be configured to extend for a predetermined period of time. Once the predetermined period of time has elapsed, the hookah device 2 can continue with the heating step 122. The user may be able to select and / or define one or more time periods. For example, options to pause heating for 1 minute, 5 minutes, or 20 minutes can be provided. Each option can include a corresponding input (e.g., a button).

[0282] The pause / resume event is typically initiated by the user. The pause / resume event can be initiated by a manual input (e.g., a button / dial, etc.) on the hookah device 2 and / or via an intermediate device 64.

[0283] During operation, the hookah device 2 is configured to monitor the position of the lid 12. The hookah device 2 is configured to monitor whether the lid 12 is set in the closed position and / or the open position. A sensor is provided to determine the position of the lid. The sensor can include optical and mechanical sensors (e.g., contact / push sensors, etc.). If the lid 12 is detected to be in the open position, the hookah device 2 is configured to initiate an end routine 112. Thus, heater 10 is configured to deactivate in response to the opening of the lid 12. Then the capsule 14 can be ejected. This can prevent the hookah device 2 from overheating.

[0284] In other embodiments, if the lid 12 is detected to be in the open position, the hookah device 2 is configured to initiate a pause event. Thus, heater 10 can be partially reduced in temperature or deactivated. Then, when the lid 12 is set in the closed position, the hookah device 2 can resume the heating step 122. Thus, the opening of the lid 12 only temporarily pauses the heating cycle.

[0285] Generally, if the lid 12 is open (i.e., heating is stopped / prevented), the device 2 may not operate or may initiate. In some embodiments, the device can be configured to shut down if the lid 12 does not return to the closed position within a predetermined period of time. For example, the predetermined period of time can include 1 second, preferably 2 seconds; 5 seconds; or 10 seconds. In some embodiments, the device 3 then operates according to the remaining period of the smoking session defined by the indicator 40 such that the active smoking session does not exceed the total period defined by the indicator 40. The active smoking session is defined as the period of time when the lid 12 of the device is closed and / or the device is not paused.

[0286] Additionally or alternatively, the hookah device 2 is configured to monitor the position of the cartridge 14. Thus, if the cartridge 14 is at least partially removed, the hookah device 2 can initiate the end routine 112 and / or pause event as described above.

[0287] The hookah device 2 continues to heat the cartridge 14 according to the heating profile 68. When the heating cycle is complete, the hookah device 2 initiates the end procedure 112. Thus, the heating of the cartridge 14 stops after a predetermined period of time. This prevents the cartridge 14 from overheating (e.g., if the user forgets to deactivate the device) and / or can help ensure that the smoking experience is consistent throughout the heating cycle. Once the heating cycle is complete, the cartridge 14 is ejected. This can help indicate to the user that the cartridge 14 should be removed.

[0288] The cartridge 14 can be ejected when it is sufficiently cooled. Thus, the cartridge 14 remains in the device 2 after the smoking session to prevent exposure to hot surfaces. In some embodiments, the cartridge 14 can be ejected after a predetermined period of time. Additionally or alternatively, the cartridge 14 is ejected once it reaches a predetermined value. For example, the cartridge 14 can be ejected when the cartridge 14 and / or the heating chamber 10 reach a temperature below 100°C, preferably below 75°C, preferably below 50°C. In other embodiments, the cartridge can remain in the device at the end of the heating cycle until it is manually removed.

[0289] Notification of the completion and / or initiation of the end routine 112 can be provided to the user. In some embodiments, the progress of the heating cycle (i.e., the progress through the heating profile) can be provided. A progress indicator can indicate the proportion of the heating cycle passed / remaining and / or the time of the heating cycle passed / remaining. The notification can be continuous / real-time. For example, the notification can indicate that 40% of the cycle remains or 40 minutes of smoking remains. The notification can be provided at one or more select points in the process. The notification can be provided at regular intervals. For example, the notification can be provided every 10% change in progress or every 10 minutes, etc. Additionally or alternatively, the notification can be provided at selected progress points. For example, the notification can occur at only 15 minutes of smoking time (if any remaining). The notification can be provided on the hookah device 2. For example, the hookah device 2 can include a progress indicator. Additionally or alternatively, an indicator can be provided on the intermediate device 64. In some embodiments, an indicator (e.g., an LED, etc.) can indicate that the heating cycle is approaching completion and / or has been completed.

[0290] Once the end routine 112 is initiated and / or if the removal of the capsule 14 is detected during and / or after the heating phase 122, the waterpipe device 2 records the authentication code of the capsule 14. Since each authentication code is unique, the waterpipe device 2 records whether an individual capsule 14 has been used (i.e., heated). The authentication code may be stored only when the capsule 14 is exposed to a predetermined temperature (e.g., a temperature above which the integrity of the smoking product is compromised). For example, the authentication code may be stored only when the capsule 14 is heated to at least 50 °C.

[0291] In some embodiments, the authentication code may be stored only when the capsule 14 is heated for a predetermined period of time. The predetermined period of time may be the time during which the smoking product can irreversibly change. The predetermined period of time may be the time during which a portion of the smoking product is consumed (i.e., a portion of the total smoking time until the product is exhausted). This allows the capsule 14 to be used for multiple smoking sessions. The period of time may be at least 50% of the total smoking time until the product is exhausted; preferably at least 75%; preferably at least 90%.

[0292] The waterpipe device 2 may store each authentication code in a memory. The authentication code may be sent (e.g., via the Internet and / or an intermediate device 64) to a remote database. During the verification phase 110, the waterpipe device 2 compares the authentication code of the capsule 14 with the authentication codes of the used capsules 14 retained in the memory / database. If the waterpipe device 2 determines that the authentication code of the present capsule 14 matches the authentication code of a used capsule, then the end routine 112 may be initiated. Thus, the waterpipe device 2 determines whether a given capsule 14 has previously been heated in the waterpipe device 2 and selectively prevents the heating of the capsule 14 if such a condition is met. Conversely, if the waterpipe device 2 determines that the authentication code of the present capsule 14 does not correspond to the authentication code of a used capsule 14, a heating cycle is initiated. This prevents the heating of empty, aged, and / or recycled capsules 14.

[0293] In some embodiments, the indicator 40 is configured to be destroyed or otherwise rendered inoperable during its heating. For example, the indicator 40 can be destroyed when reaching a temperature of at least 60 °C, preferably at least 80 °C, preferably at least 100 °C. The indicator 40 can be configured to melt, burn, decompose, pyrolyze, evaporate, and / or otherwise change form / stage. The indicator 40 can be configured to be destroyed due to its inherent properties. For example, the heating temperature is higher than the melting / burning temperature of the indicator 40 and / or its critical components. Additionally or alternatively, the indicator 40 can include a predetermined failure point configured to be destroyed at a predetermined temperature. For example, the indicator 40 can include a fuse configured to melt / burn during heating, rendering the indicator 40 inoperable. If the indicator 40 is destroyed, the reading step 108 and / or the integrity step 110 will fail when reinserted into the hookah device 2, preventing the reuse of the capsule 14. In some embodiments, the indicator 40 can be physically or partially destroyed by removing the indicator from the capsule 14. For example, the indicator 40 can be configured to delaminate upon removal and / or can be brittle.

[0294] In some embodiments, the hookah device 2 and / or the mobile device 64 are configured to initiate a "termination" routine. The termination routine is configured to render the indicator 40 at least partially inoperable to prevent the reuse of the indicator 40. In some embodiments, the device 2 can be configured to erase at least a portion of the memory of the indicator 30. The device 2 can delete any portion of the memory of the indicator 30 required for successful operation during the above-mentioned integrity check step 110. In some embodiments, the device 2 can write a flag or other signal to the memory of the indicator 30 to indicate that the capsule has been used / invalidated.

[0295] In some embodiments, the indicator 30 is configured to delete at least a portion of its memory upon receiving a code or signal. For example, the hookah device 2 and / or the mobile device 64 can be configured to transmit a "termination" signal or code. Upon receiving the code, the indicator 30 deletes all or at least a portion of the memory of the indicator. The indicator 30 can delete any selected portion of the memory to prevent its use, as described above. The code or signal can include a unique code or signal recognized by the indicator 30.

[0296] Now referring to Figure 30 , the memory 128 on the indicator 30 is operatively divided into two parts. The first part 130 provides a "common" memory portion. The common portion 130 is accessible without authentication. Thus, the common portion 130 can be accessed by any device suitable for interrogating the indicator 30. For example, the mobile device 64 can read / interrogate the common portion 130 of the memory.

[0297] The second part 132 provides a "dedicated" part. The dedicated part 132 can only be accessed via authentication. Authentication can be provided as previously described. Thus, only authenticated devices can access the dedicated memory 132. This ensures that only specific devices can access the dedicated part, thus ensuring data integrity.

[0298] The common part 130 can include general or common data. For example, the ID or name / aroma ID of the capsule 14 can be located in the common part 130. This allows any device to identify the contents of the capsule 14. In contrast, the dedicated part 132 contains dedicated or appropriate data and should therefore only be read by authorized devices. For example, the dedicated part 132 contains one or more heating profiles 68, manufacturing data, and / or personal data (i.e., data that may be subject to privacy regulations).

[0299] The common part 130 can rewrite the memory. Thus, the user may be able to write data to the common part 130. The user may be able to specify their usage and record the usage in the common part 130. For example, the user can use the mobile device 64 to record their desired intensity on the memory 128 of the capsule. The hookah device 128 can then read the user preference and select an appropriate heating profile accordingly. The user can record the number of users or other user preferences.

[0300] The common part 130 can record the usage data of the capsule 14. The usage data can include the time the capsule 14 has been heated, the time remaining before the product is exhausted, or the proportion of the product 30 consumed. This can provide an indication to the user of how much smoking product 30 remains. The usage data can be read by the hookah device 2, allowing the continuation of a previous heated smoking session (i.e., resuming the heating profile 68). Thus, the capsule 14 serves as an intermediate for facilitating communication between the hookah device 2 and the mobile device 64.

[0301] In some embodiments, the data on the indicator 40 (i.e., its common part and / or dedicated part) can be rewritable. For example, the hookah device 2 can format the data on the indicator and / or add a read count (i.e., the number of times the hookah device has read / interrogated the memory).

[0302] The smoking product 30 can include any suitable form or composition. The smoking product includes a "fog generator". The fog generator is configured to create a cloud upon evaporation. The fog generator includes a volatile material that is configured to provide a light-scattering cloud in an evaporated state. The fog generator contains a polyol. The polyol can include one or more of the following: glycerol; 1,2-propanediol; 1,3-propanediol; 1,2-butanediol; 1,3-butanediol; 1,4-butanediol; 2,3-butanediol; 1,2,4-butanetriol; triethylene glycol; glyceryl triacetate; mannitol; sorbitol; xylitol; inositol; isosorbide; polydextrose; or dianhydro-D-glucitol. The polyol can contain "sugar alcohols" (hydrogenated sugars).

[0303] The product can include a sweetener. The sweetener can include carbohydrate sweeteners (e.g., monosaccharides having 5 or 6 carbon atoms), such as one or more of the following: arabinose, xylose, ribose, glucose, mannose, galactose, fructose, dextrose, or sorbose. The sweetener can include disaccharides, e.g., one or more of the following: sucrose, such as cane or beet sugar; lactose; maltose; or cellobiose. The sweetener can include polysaccharides, e.g., one or more of the following: partially hydrolyzed starch or dextrin; polyols, such as sorbitol, mannitol, xylitol; and mixtures with one or more of the above sugars. The sweetener can include complex sugar / carbohydrate mixtures (e.g., natural sugar products). The sweetener can include one or more of the following: molasses; invert syrup; corn (maize) syrup; maple syrup; golden syrup; honey, etc.
