Description

Technical Field

[0001] The present disclosure relates to a capsule for containing a consumable material, and more particularly, but not limited thereto, to a capsule for use with an electronic hookah device.

Background Art

[0002] An electronic shisha or hookah pipe provides a convenient means for smoking shisha products. A prior art hookah device is shown in WO 2015 / 172224 pamphlet. The device is configured to heat a capsule that contains a smoking product, such as mu’assel or shisha. The capsule is received in a heating chamber of the device to vaporize and / or combust the smoking product to produce an aerosol that a user can inhale.

[0003] The inventor has found many problems with such prior art devices. Typically, such devices heat the capsule at a predetermined fixed temperature. Such a temperature may be optimized with respect to the standard composition of the smoking product.

[0004] When 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 contains components configured to vaporize at a low temperature, heating the product at the standard temperature may cause the product to burn. Conversely, if the components are configured to be vaporized at a high temperature, the standard temperature may result in a weak-flavored smoke. Thus, conventional devices limit the compositions suitable for use with them, and the use of non-standard capsules can give the user a harmful experience.

[0005] Conventional capsules are configured to be substantially sealed. This preserves the freshness of the ingredients. When the smoking product is used up, the capsule is discarded. However, some users may refill the capsule with smoking products from different sources. This can be a problem, for example, in a café or bar, as the capsule can be refilled with a smoking product that is of inferior or less fresh quality than when it was supplied as a sealed capsule. This can result in a poor smoking experience for the user and / or the system may generate harmful compounds due to inaccurate or overheated smoking products.

[0006] Users may accidentally heat an empty capsule and / or forget to turn off the device when the smoking session is complete. This can damage the device, pose a fire risk, or present a harmful health risk to the user if they attempt to inhale from the device while the used capsule is being heated.

DETAILED DESCRIPTION OF THE INVENTION

[0057] Figure 1 shows an example of a water pipe 2, which is referred to herein as a hookah device or a shisha pipe, but it can be understood that the pipe may be used to vaporize and inhale a variety of consumable substances. The device 2 in this example is electrically heated and / or electronically controlled.

[0058] The water pipe 2 comprises a base 4. The base 4 may comprise a wide portion or area to prevent the device 2 from tipping over. An electronics enclosure 6 is provided. The device 2 comprises a tank 8 configured to be filled with a liquid coolant (e.g., water). Thus, the tank 8 provides a container / reservoir. The electronics enclosure 6 and the tank 8 may be separable / removable. This allows access to the opening of the tank 8 for filling / draining.

[0059] The electronics enclosure 6 comprises a lid 12 to provide an opening thereto. As shown in FIG. 2, a heater 10 is mounted to the electronics enclosure 6. The heater 10 is configured to receive a capsule 14 containing a consumable / smoking product. The heater 10 heats the capsule 14 to vaporize or disperse one or more components of the consumable. Thus, the heater 10 forms a heating chamber or container. One or more heating elements may be provided in the wall of the heating chamber 10, inside the wall, and / or integrally with the wall. The heating chamber 10 comprises a thermally conductive material (e.g., metal). The capsule 14 fits closely and / or engages with the heating chamber 10. Thus, heat enters the capsule 14 through the wall of the heating chamber 10 during use.

[0060] Typically, the heating element comprises a resistive element (i.e., heated by the current flowing therethrough). However, any suitable means may be used to heat the heating chamber 10 and / or the capsule 14, such as induction 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, and one or more of these may be used. The heating chamber 10 comprises a thermally conductive material, such as metal.

[0061] As best seen in FIG. 3, a plurality of openings 16 are provided in the capsule 14 to allow the vaporized product to escape through the openings. The openings 16 typically have a diameter of less than 5 mm. The vaporized product enters the heating chamber 10 during heating of the capsule 14. The lid 12 and / or the heating chamber 10 comprises one or more air inlets 17 for introducing air into the heating chamber. This air then mixes with the vaporized product in the heating chamber 10.

[0062] The heater 10 may be controlled by the electronics in the electronics compartment 6 (e.g., via a heater controller). The electronics may comprise a microcontroller / microprocessor, memory (volatile and / or non-volatile), and / or an electrical regulation circuit (e.g., a power limiter and / or a controller). The electronics compartment 6 comprises any suitable components for heating the heater 10. A power source is provided. The power source may be a commercial power supply. In addition to or instead of this, the power source comprises a battery or the like. The battery may be removable and / or rechargeable. A power switch 18 may be provided. Thus, the device 2 and / or the heater 10 may be manually operated / stopped. In addition to or instead of this, the heater 10 may be operated / stopped by a lock or closure mechanism configured to engage or secure to the lid or other component of the heating chamber, thereby forming a safe enclosure around the heater during use. The heater may be inoperable when the lid is open or unlocked / latched.

[0063] The heating chamber 10 is operably connected to the tank 8 via a conduit 15 passing through the electronics compartment 6. Thus, the vaporized smoking product passes from the conduit 15 through the coolant in the tank 8, where it is cooled and / or filtered. The conduit 15 passes through the electronics compartment 6. The conduit 15 is sealed from the electronics compartment 6 to prevent its contamination.

[0064] The suction hose 20 is provided in communication with a portion of the tank 8 above the coolant level. The suction hose comprises a mouthpiece 22. The mouthpiece 22 may be detachable / removable. Air can be drawn through the heated capsule, and the vaporized product of the capsule can be carried by an air stream passing through the conduit 15. Thus, the user can inhale to draw the vaporized product through the device 2 and exhale through the hose 20. Such a system emulates a conventional non-powered shisha / hookah pipe.

[0065] It can be understood that the device 2 shown in FIGS. 1 and 2 is merely illustrative, 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 the vaporized smoking product during use passes upward through the device 2. Thus, the electronics compartment 6 may form the base portion of the device 2. The conduit 15 may extend from the heater into the coolant and pass the vaporized product through the coolant. The capsule 14 may be inserted into the base of the device 2.

[0066] Examples of suitable hookahs 2 and associated heaters 10 can be found in the previously published patent applications International Publication No. WO 2017 / 080545 and International Publication No. WO 2015 / 172224, the contents of which are incorporated herein by reference. Such details are not repeated herein for the sake of brevity.

[0067] Referring to FIGS. 3 and 4, the capsule 14 comprises an upper end wall 24 and a lower end wall / base 26. The upper end wall 24 and the lower end wall 26 are connected via side walls 28. The side walls 28 are substantially continuous. Thus, the upper end wall, the lower end wall, and the side walls provide a housing / cavity for the smoking product 30. It can be understood that the terms "upper", "lower", and "side" are used merely to assist in the description of the capsule, and the capsule may be used in any suitable orientation during use.

[0068] A plurality of openings 16a, 16b are provided in the upper end wall 24 and the lower end wall 26, respectively. During use, air passes through the openings in the upper end wall 24 and into / through the smoking article 30. The smoking article 30 is heated and vaporized. The air carries the vaporized product with it to the capsule 14 and exits through the openings in the lower end wall 26. Such a configuration results in pre-packaged or pre-filled capsules.

[0069] In some embodiments, the opening 16 may be provided only in one of the upper end wall 24 and the lower end wall 26. Thus, air enters and exits the capsule through the same opening 16. In some embodiments, the opening 16 may be provided in the side wall 28. It can be understood that any suitable configuration may be provided to release vapor from the capsule 14. However, this configuration is beneficial as it allows the capsule 14 to be heated through the side wall 28 and air to pass through the upper / lower end of the capsule 14. This can help to ensure that the air flow through the capsule 14 does not impede its heating.

[0070] In some embodiments, the device 2 is configured to pierce, perforate, or otherwise open the capsule 14 to allow air to enter and exit. Thus, the capsule 14 may be sealed prior to opening. This can help to maintain freshness. The upper end wall can be pierced by a suitable formation in the lid 12 and / or the lower end face can be pierced by the end of the smoke conduit 15. Thus, the opening need not be formed at the time of manufacture and can be formed during use of the capsule.

[0071] The capsule 14 may comprise a seal 32 to cover the opening 16. The seal is removed prior to use to expose the opening 16. Thus, the seal 32 helps to maintain freshness. The seal 32 may be provided on the upper / lower end face / side as required. The seal may be attached to the capsule 14 using a peelable adhesive or the like. The seal 32 may comprise a pull tab or the like.

[0072] According to aspects of the present invention, the entire capsule (regardless of the presence or absence of one or more seals 32 covering the opening 16) may be held in a sealed pouch, package or sleeve so as to provide a retail product that can maintain the capsule in a fresh state over a long period of time. The pouch may be filled / flushed with an inert gas such as nitrogen. Thus, either or both of the capsule and the pouch can be filled with gas to help preserve the smoking product therein until use. Even if the capsule itself is filled with air or not flushed, for example, if the gas in the pouch and the air in the capsule mix and the total oxygen content of the pouch is low enough to promote a long capsule shelf life, it has been found that flushing the pouch with an appropriate gas may be sufficient. The pouch may optionally have a metal / foil layer, such as a polymer layer.

[0073] The upper surface 24 may comprise a closure body (e.g., a lid). Thereby, the product 30 can be placed in the capsule 14. The opening 16a may or may not be provided in the lid. The closure body is then fixed to the capsule to hold the product 30 therein. The closure body may be fixed to the upper edge of the side wall 28. The side wall 28 may comprise an outwardly extending rim / flange 34. The closure body may engage, seal, and / or deform the rim / flange 34. The lid 12 may engage the rim 34 and / or the closure body attached thereto to form a seal therebetween. The rim 34 may be curled and / or comprise a reinforcing element. The rim 34 may be planar and / or annular. The rim 34 may be parallel to the upper surface 24 and / or the lower surface 26.

[0074] The closure body may be permanently fixed to the capsule 14 to prevent removal of the product 30 from the capsule. For example, the closure body may be crimped or adhered to the capsule 14. The closure body may be crimped to the rim 34.

[0075] In other embodiments, the closure body can be releasably connected to the capsule 14, thereby enabling the user to access the interior of the capsule 14 (i.e., refill the capsule 14). The closure body may be connected to the capsule via releasable connecting means. The releasable connecting means may comprise one or more of a press fit, snap fit, screw thread, releasable latch or clip, clamp, hook and loop, press stud, bayonet, etc.

[0076] In this embodiment, the lower end face 26 is formed integrally with the capsule 14 (i.e., integral with the side wall 28). Accordingly, the opening 16b is formed in the capsule 14. In an alternative embodiment, the lower end face 26 may comprise a permanent / removable closure body.

[0077] The capsule 14 comprises an upper end wall 24 having a larger planar area than the lower end wall 26 such that the shape of the capsule tapers / narrows. The capsule 14 tapers towards the lower end wall 26. This aids in release from the heating chamber 10. Accordingly, the capsule 14 has a trapezoidal cross-section (in side view). The taper shown in the figure is merely exemplary and the side wall 28 may be tapered at any suitable angle. For example, the side wall 28 may taper between 1 degree and 45 degrees, preferably between 1 degree and 30 degrees, preferably between 3 and 20 degrees. Typically, the side wall 28 tapers at least 1 degree, preferably at least 3 degrees.

[0078] The capsule 14 has a circular profile (in 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 have any shape suitable for the intended purpose. Different shaped capsules can be provided, for example, shaped to achieve a desired contact with the interior of the device 2, for example, for good thermal contact with the heater 10. For example, oval or polygonal planar capsules can be accommodated.

[0079] The capsule 14 is stackable. The upper and lower surfaces of the capsule 14 may be provided with complementary recesses / projections to assist stacking. For example, the base may have ridges / projections configured to engage with the grooves / recesses of the upper surface 24 and / or the rim 34, and vice versa.

[0080] When the capsules 14 are stackable, a plurality of capsules can be introduced simultaneously into the heating chamber of the device in the same usage session. The capsules 14 can collectively define a substantially continuous fluid passage therethrough. This can provide the user with a customized combination of active ingredients, compositions, and / or flavors, depending on preference.

[0081] 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 proper heat conduction to 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 coloring pigment or the like. The coating is temperature-stable (i.e., does not decompose at high temperatures).

[0082] A second embodiment of the capsule 14 is shown in FIGS. 5 and 6. The second embodiment may be substantially the same as the first embodiment, and like features are not repeated. The lower wall 26 and the side wall 28 form a continuously curved base. The wall 26 curves inwardly such that the capsule 14 tapers towards its lower end.

[0083] The base / lower wall 26 of the capsule 14 comprises 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 / arc-shaped. Thus, the base 26 of the capsule 12 is dome-shaped. The recess 36 comprises a plurality of openings 16b that extend through the wall of the base 26. The openings allow air / vapour to pass through the capsule 12 during use (i.e., provide a unidirectional air flow). During use, the smoking article 30 is filled at a position below the recess openings 16b such that liquid or other smoking article does not flow therethrough. A removable seal 32 may extend across the recess 36. A further seal 32 may seal the upper end of the capsule 14.

[0084] Referring to FIG. 7, the capsule 14 comprises an indicator 40. Generally speaking, the indicator 40 is configured to indicate or otherwise communicate one or more characteristics of the capsule 14 and / or its contents. In certain embodiments, the indicator 40 indicates the specific formulation of the smoking article 30 and / or its heating profile. Thus, the indicator 40 can provide a label, tag, etc. Details of the content of the indicator 40 will be described later.

[0085] In the first embodiment, the indicator 40 includes an electronic memory device. Thus, the indicator 40 and / or the data therein can be electronically read, downloaded, and / or otherwise examined via the sensor 42 of the hook device 2 (see FIG. 8). The memory device may comprise any suitable form. Typically, the memory device is non-volatile / permanent. Thereby, the data of the storage device is retained without requiring power. The memory device can include EEPROM, flash memory, or other suitable technologies. The memory can store at least 32 bits, preferably at least 128 bits, preferably at least 256 bits of data. The data can be stored with or without encryption. The indicator includes a memory controller for controlling the reading / writing of the memory and / or for controlling communication with the sensor 42.

[0086] In some examples, the memory device 56 includes a read-only memory (ROM). Thereby, unauthorized alteration of the data of the indicator 40 is prevented. The physical memory may be rewritable, but the indicator 40 itself and / or any external device (e.g., the hook device 2) may be prevented from writing and / or rewriting data to the memory device 56.

[0087] In the embodiment shown in FIG. 8, the indicator 40 is configured to physically contact the sensor 42 of the device. This provides a "wired" or "contact" system. The indicator 40 is provided on the outer portion of the capsule 14 to enable contact with the device 2. The indicator 40 may be provided on the side wall 28, the bottom wall 26, and / or the upper end wall 24 of the capsule 14. Preferably, the indicator 40 is provided on the bottom wall 26 to prevent interference with the heat flow to the capsule 14 through its side wall 28. In some embodiments, the indicator 40 is provided on a part of the capsule 14 that protrudes therefrom, such as the rim 34. Thus, the indicator 40 is outside the heating chamber 10 during use.

[0088] The device sensor 42 is provided at a position corresponding to the indicator 40 and provides contact with the indicator during use. Thus, the sensor 42 is provided above / within the heating chamber 10. The sensor 42 may be provided at the lower end 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 flat / parallel to the indicator 40.

[0089] In some embodiments, the sensor 42 is provided on the lid 12. Thus, the sensor 42 is provided on a movable closure for the heating chamber 10. Thus, the indicator 40 is provided on the upper surface 24 of the capsule 14. This can prevent damage to the indicator 40 since the upper surface 24 is typically cooler than the rest of the capsule 14 during use. The indicator 40 may be provided offset from the center of the capsule 14. For example, the indicator 40 is provided adjacent to the side wall 28 of the capsule 14. This can reduce the breakage / blockage of the inlet opening 16a. In other embodiments, the indicator 40 / sensor 42 is provided at the center of the capsule 14 so that the capsule 14 can be provided in any orientation. The sensor 42 can be operably connected to the electronics compartment 6 via a cable 50 or the like (see FIG. 2).

[0090] Due to the high temperature of the heating chamber 10, it can be understood that an apparatus or system 48 configured to read / interrogate an indicator may be displaced away from the sensor 42 to prevent damage to the sensor 42. Thus, the sensor 42 may simply comprise one or more electrical contacts, etc. The sensor 42 is then operatively connected to the sensor device 48 (e.g., via a cable 50, etc.). The contacts may be biased to engage the indicator 40. This improves the electrical contact. The contacts may be spring-mounted or spring-loaded. The contacts may be gold-plated, etc. If the indicator 40 is provided on the rim 34, the lid 12 may bias the sensor 42 into engagement with the indicator 40. For example, the indicator 40 / sensor 42 is interposed between the lid 12 and the rim / outer edge 52 of the heating chamber 10.

[0091] In some embodiments, the communication between the device 2 and the capsule 14 is wireless. This configuration is shown in FIGS. 10A and 10B. Thus, the sensor 42 is configured to wirelessly communicate with the indicator 32. The sensor 42 comprises a wireless communication transmitter and / or receiver. The indicator 40 thus comprises a wireless communication transmitter and / or receiver. For example, the sensor 42 and / or the indicator 40 comprises an antenna, etc.

[0092] In some embodiments, the indicator 40 comprises a passive device. The indicator 40 does not comprise 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 supply power to the electronics of the indicator 40 and transmit a return signal. Thereafter, the sensor 42 receives the return signal. This can provide, for example, an RFID system. This can make the indicator 40 low-cost and of a simple structure.

[0093] The sensor 42 may be configured to send interrogation signals at predetermined intervals (e.g., when power is supplied to the system). Thereby, the sensor 42 can detect when the capsule 14 is received by the device. Typically, the interval is from 0.1 second to 1 second. In other embodiments, the interrogation signal is provided via a manual input by the user. For example, the user can press a button to activate the interrogation signal. Then, the sensor 42 may send a predetermined number of interrogation signals, may repeatedly send the interrogation signals over a predetermined period of time, and / or may repeatedly send the interrogation signals until the user releases / deactivates the manual input.

[0094] In other embodiments, the indicator 40 comprises an active device. Accordingly, the indicator 40 comprises a dedicated power source (e.g., a battery). The indicator 40 is configured to send a signal. The signal may comprise an identification signal or a handshake or the like. Thereafter, the signal is received by the sensor 42. Then, the sensor 42 can send a confirmation response signal. Then, the indicator 40 can send the data contained therein. In other embodiments, the indicator 40 can simply send data without a handshake configuration (e.g., broadcast the signal).

[0095] Wireless communication may use any suitable radio frequency, e.g., LF, HF, UHF, and / or microwave frequencies. The 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 serves to ensure that the correct capsule is interrogated by the sensor 42 and / or to reduce power consumption. The power of the wireless communication system may be less than 1 W.

[0096] The wireless sensor 42 and / or any associated reading device 48 can be understood to be placed at / into any suitable position for reading the indicator 40. The sensor 42 may be provided in the vicinity of or adjacent to the heating chamber 10 and / or on the lid 12. The sensor 42 may be displaced away from the heating chamber 10 (i.e., its surface) and / or the capsule 14. Typically, the sensor 42 is housed in the electronics enclosure 6. The heating chamber 10 may be configured to enable wireless transmission. For example, the heating chamber 10 may comprise an opening or a non-conductive (e.g., ceramic) portion to allow transmission.

[0097] Accordingly, the wireless indicator 40 may be provided on / at any suitable position of the capsule 14. The indicator 40 is typically provided on the exterior of the capsule 14 (e.g., the lower wall 26, the upper end wall 24, or the side wall 28). This enables easier wireless transmission. In an alternative, the indicator 40 is housed within the capsule 14. The indicator 40 may be fixed inside the capsule wall, in its internal enclosure, or may be loosely housed therein.

[0098] In the particular embodiment shown in FIG. 10B, the indicator 40 is provided on the rim 34 of the capsule 14. The indicator 40 may be provided on the lower surface 35A of the rim 34 (i.e., the side facing the side wall 28 and / or the lower wall). In addition to or instead of this, the indicator 40 is provided on the upper side. The indicator 40 may be fully or partially embedded in the rim 34. For example, the indicator 40 may be flush with the surface of the rim 34. The indicator 40 can extend around the perimeter or circumference of the rim 34. Accordingly, the indicator 40 may be arcuate, angled, or convex / curved. The indicator 40 may extend partially or fully around the rim 34.

[0099] As shown in FIG. 10C, the sensor 42 is provided at a position to read the indicator 40 accordingly. The sensor 42 is provided adjacent to the heating chamber 10. The sensor 42 is provided on or adjacent to the shoulder / rim / outer edge 52 of the heating chamber 10. Alternatively, the sensor 42 is provided on / above the lid 12. Therefore, the indicator 40 and / or the sensor 42 are removed from the heating zone and / or the smoke path of the capsule 14. This can help prevent contamination by particulate matter in the vaporized smoking product and / or thermal damage to the sensor 42.

[0100] The indicator 40 has a thickness such that the wall 28 of the capsule 14 maintains contact with the wall 46 of the heating chamber 10. Similarly, the thickness is such that the rim 34 can be positioned flat against the rim 52 of the heating chamber. The indicator 40 has a thickness of 1 mm or less, preferably 0.5 mm or less.

[0101] Referring to FIG. 10D, the indicator 40 can be attached to the carrier 55. The carrier is attached to the side wall 28 of the capsule 14. Therefore, the carrier 55 can be attached circumferentially. The carrier 55 may be provided adjacent to or in contact with the capsule rim 34. The carrier 55 entirely surrounds the capsule 14. Therefore, the carrier 55 is annular or ring-shaped. The carrier 55 can provide a collar, band, or sleeve. In some embodiments, the carrier 55 may partially surround the capsule 55 (e.g., the carrier 55 is crescent-shaped or C-shaped).

[0102] The carrier 55 is a polymer. The carrier 55 may include any suitable polymer. The carrier may include a high-temperature thermoplastic. This prevents combustion and decomposition during heating. The carrier 55 may include one or more of polyphenylene sulfide (PPS), polyethersulfone (PESU), polyphthalamide (PPA), polyphenylsulfone (PPSU), polyurethane, silicone, and combinations thereof. The polymer generally includes at least one aromatic functional group.

[0103] The carrier 55 is removable / separable from the capsule 14. This enables separate recycling / disposal of the carrier 55 and the capsule 14. The carrier 55 can form an interference fit / friction fit. Thus, the carrier 55 is loosely held in place (i.e., not permanently fixed) in the capsule 14. The carrier 55 is sized to provide a close / tight fit with the capsule. This enables easy removal. In other embodiments, the carrier 55 is permanently fixed to the capsule 14 using, for example, adhesives, fasteners, etc.

[0104] In some embodiments, the indicator 40 is provided on the tab 57 of the carrier. The tab 57 provides a flap, lip, or protrusion that extends outwardly from the outside of the carrier 57. The tab 57 extends outwardly in substantially the same direction as the rim 34 of the capsule 14. Thus, the tab 57 is provided adjacent to or in contact with the rim 34. The tab 57 projects away from the capsule sidewall 28, thereby preventing interference from the metal of the sidewall 28 when the indicator 40 is in wireless communication with the sensor 42.

[0105] The tab 57 extends only around a portion of the circumference of the capsule 14. For example, the tab 57 can extend around the circumference of the capsule 14 by about 45 degrees. Thus, the tab 57 provides an individual portion. In an alternative embodiment, the tab 57 extends around the entire circumference of the capsule. Thus, the tab 57 can form a rim or flange. Thus, the indicator 40 may be curved / arcuate as shown in FIG. 10B.

[0106] Indicator 40 is at least partially embedded in tab 57. Preferably, indicator 40 is fully embedded / enclosed in tab 57. This helps prevent damage to indicator 40. Indicator 40 may be insert molded or overmolded onto tab 57. Tab 57 can include the same material as the colored portion of carrier 55. Alternatively, tab 57 may include a different material than the colored portion, for example, to optimize the coupling or embedding of indicator 40. Tab 57 may be permanently separated from capsule 14 by an irreversible operation. For example, tab 57 may have a weak portion.

[0107] In other embodiments, tab 57 is not provided and the indicator is attached to the colored portion of carrier 55.

[0108] As shown in FIG. 10E, sensor 42 is provided at a position suitable for reading the indicator of carrier 55 / tab 57. Sensor 42 may be at the position as described with reference to FIG. 10C. In some embodiments, tab 57 is inclined towards the base 26 of capsule 14 (e.g., away from rim 34). Thus, tab 57 is biased towards sensor 42 when capsule 14 is in heating chamber 10. This helps enable indicator 40 to communicate with sensor 42. Tab 57 is sandwiched between capsule rim 34 and heating chamber rim 52. Capsule rim 34 can engage tab 57 and / or bias tab 57 to engage heating chamber rim 52.

[0109] A further embodiment of the carrier 55 is shown in FIG. 10F. The carrier 55 is configured to engage with the rim / flange 34 of the capsule 14. The carrier 55 may comprise a recess / groove configured to receive the rim 34. The carrier 55 can include a snap fit or an interference fit with the rim 34. The indicator 40 is mounted on a carriage or insert 59 configured to be received by the carrier. The carriage 59 is received in a slot or recess of the tab 57. Thus, the carriage 59 is insertable into the tab 57. The indicator 40 may be adhered or otherwise fixed to the carriage 59. In other embodiments, the indicator 40 may be loosely held by the carriage 59. For example, the indicator 40 may be received in a recess of the carriage 59.

[0110] The carriage 59 may be sealed within the carrier 55 or, alternatively, may be permanently fixed. This helps to prevent unauthorized tampering of the indicator 40. The carriage 59 may be adhered to the tab 57 and / or welded / fused to the tab. In other embodiments, the carriage may be held via a latch or the like.

[0111] In some embodiments, the thickness of the tab 57 is 1 mm or less. Thus, the tab 57 may form a label and / or may be flexible. This causes the capsule 14 to maintain close contact with the heating chamber 10. In addition to or instead of this, a recess in the heating chamber rim 52 is provided to accommodate the tab 57.

[0112] 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 into the heating chamber 10. This enables the device 2 to communicate with the capsule 14 which is configured to be heated. In an alternative embodiment, the device 2 may be configured to communicate with a capsule 14 that is not provided in the heating chamber 10 (i.e., when the capsule 14 is outside the device 2). The sensor 42 may be provided on an external part of the device 2 / adjacent to an external part of the device 2. For example, the sensor 42 may be provided on an external part of the electronic device housing 6 and / or the lid 12. Alternatively, the sensor 42 is positioned such that it can wirelessly communicate with the capsule 14 when the capsule 14 is outside the device 2. Then, the user can bring the sensor 42 into contact with the capsule 14 and / or move the capsule 14 into its wireless range to initiate communication between them.

[0113] The indicator 40 is shown in detail in FIG. 11. The indicator 40 includes a substrate 54. The substrate 54 can include a polymer or plastic. The substrate 54 may be flexible / curveable. This enables the indicator 40 to be attached to a non-planar side surface (e.g., the side wall 28) of the capsule 14. The substrate may include an adhesive or the like for attaching to the capsule 14 (e.g., to provide a sticker or label). The indicator 40 may be attached after / during the manufacturing process of the capsule 14.

[0114] The memory device 56 is provided on the substrate 54 and / or incorporated in other ways. A plurality of contacts 58 are provided for contacting the sensor 42. Any number of contacts 58 can be provided. The contacts 58 are operably connected to the memory device 56 (e.g., tracks / wires).

[0115] A wireless indicator 40 is shown in FIG. 12. The wireless indicator 40 may be substantially the same as the contact indicator 40, but an antenna 60 is provided instead of the contact 58. The antenna 60 is generally in a folded form. For example, the antenna may be labyrinthine, spiral / concentric, wavy, and / or branched.

[0116] In an embodiment where the indicator 40 is provided on the rim 34, the antenna 60 may extend completely and / or partially around the rim 34. For example, the antenna may be provided concentrically / spirally around the rim 34. Thereby, the indicator 40 can be read in any orientation thereof. The antenna 60 and / or the memory 56 may be mounted on the rim 34 or embedded in the rim.

[0117] In some embodiments, the indicator 40 may be configured to be optically read by the sensor 42. Thus, the indicator 40 comprises passive (i.e., non-electric) markings. Thus, the indicator 40 comprises a visual indicator. The indicator 40 may be printed or otherwise deposited on the capsule 14. The indicator may be provided on a substrate (e.g., a sticker / label) and / or printed / deposited directly on the capsule 14.

[0118] The sensor 42 comprises an optical sensor, such as a photodiode or a CCD array (e.g., a camera). The sensor 42 can comprise a light source for illuminating the indicator 40. For example, the light source may comprise a scanning laser and / or a static light source (e.g., an LED). The sensor 42 comprises an image processing system and / or is operably connected to an image processing system. The image processing system decodes the visual indicator 40 and extracts / determines the data contained in the indicator 40. Thus, the image processing system converts the visual indicator 40 into machine-readable data / codes.

[0119] In the embodiment shown in FIG. 13, the indicator 40 comprises a two-dimensional or matrix code. The code may constitute a QR code (registered trademark). The code can provide a binary code (i.e., the printed portion indicates 1 or 0).

[0120] In the embodiment shown in FIG. 14, the indicator 40 comprises a bar code. The bar code may have any suitable form. The bar code may be provided with human-readable characters (e.g., to enable its reading by optical character recognition).

[0121] In the embodiment shown in FIG. 15, the indicator 40 comprises a color code. The color of the color code (e.g., wavelength / RGB) is determined by the sensor 42, thereby enabling data to be provided to the device. The color may be pre-associated with a particular instruction, code, or product, etc. For example, a particular first smoking product formulation is associated with a first color, and a particular second smoking product formulation is associated with a second color that includes a code, etc. Alternatively, a particular color is associated with a particular coded entity (e.g., letter, number, character, character string, etc.). Thus, the color of the indicator 40 can provide a pseudo code. For example, the RGB value of the indicator 40 may be determined. The RGB value may be associated with particular data in the database of the device 2. And the system searches for particular data according to the observed RGB value.

[0122] The indicator 40 can include any number of predetermined colors according to the sensitivity of the system. For example, the device 2 may be configured to detect 5 to 100 different / discrete colors.

[0123] In some embodiments, a plurality of coloring 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 are detectable, the indicator 40 shown in FIG. 15 can code 1000 discrete variations. This enables coding of strings etc. and / or more variations. Although three indicators 40a - c are shown in FIG. 15, it can be understood that any number of indicators may be used.

[0124] 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 shading / hatching 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.

[0125] It can be understood that the indicator 40 may comprise any suitable human and / or machine - readable code. For example, the code may be provided directly on the capsule 14. The code can include binary, alphanumeric and / or symbol codes. The code can include a plurality of dots or markings. The spatial position and / or orientation of the dots / markings can define the code. The code can include a human - readable code. For example, the smoking formulation may be printed on the capsule (e.g., "strawberry flavor"). The image - processing system may comprise a character / image recognition system (e.g., OCR) for reading / determining the code. The image - processing system can then execute, transfer, and / or process the code accordingly. Such a configuration enables 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.

[0126] In some embodiments, the capsule 14 may be shaped and / or deformed to provide an indicator 40. The capsule 14 may include recesses, protrusions, ridges, and / or depressions for providing a code. For example, a QR code (registered trademark) or barcode can be embossed / debossed on the capsule surface. In other examples, a plurality of protrusions / recesses can provide an encoded string.

[0127] In some embodiments, the indicator 40 is detachable or removable from the capsule 14. For example, the indicator 40 may include a detachable label or tag. The indicator 40 may be peelable from the capsule 14. The indicator 40 may include a weakened line (e.g., a perforation) that enables removal from the capsule 14. The indicator 40 may be provided on one or more of the removable seals 32.

[0128] In some embodiments, the indicator 40 is separate from or removed from the capsule 14. The indicator 40 may be provided on a separate label, card, tag, or other substrate. The indicator 40 may be loosely held by the capsule 14. For example, the indicator 40 and the capsule 14 may be loosely held in a package or wrapper that includes the indicator 40 and the capsule 14. The indicator 40 may be attached to the capsule 14 via a wire, string, adhesive, or the like.

[0129] In some embodiments, the indicator 40 is configured to change in response to the use of the capsule 14. The indicator 40 may be configured to change in response to exposure of the capsule 14 to heat. This provides an indicator that the capsule 14 has already been used and / or that the capsule 14 may have been exposed to an undesirable temperature during its transport and / or storage. Thus, the indicator 40 provides an indication that the capsule 14 can provide a sub-optimal smoking experience. The sensor 32 can include an illumination device for illuminating the indicator 40.

[0130] Indicator 40 includes a thermochromic material. Thus, the material changes its visual appearance during exposure to high temperature (i.e., higher than ambient temperature). The material may include pigments and the like. The pigments are incorporated into the ink. The ink is deposited / printed on the capsule 14. The exact form of such thermochromic materials is not relevant to the present invention at this time, and suitable formulations or compositions may be known to those skilled in the art. The thermochromic material may include one or more of liquid crystals, leuco dyes, metal oxides, and / or metal complexes.

[0131] In this embodiment, the thermochromic indicator 40 is provided on the upper surface 24 and / or the rim 34 of the capsule (e.g., the capsule closure). Thus, the sensor 42 is provided on / above the lid 12 of the device 2. The sensor 42 provides a line of sight with the indicator. In this way, the sensor 42 is provided on the lower side of the lid 12 (as shown in 9, for example). The sensor 42 comprises a suitable optical sensor for detecting the thermochromic change of the indicator 40 (e.g., a CCD or a photodiode).

[0132] Indicator 40 may be provided on the upper seal 32. Thus, as shown in FIG. 17, when the seal 32 is removed from the closure 24, the portion of the indicator 40 on the seal 32 is removed. Thus, a part of the indicator 40 is removable. The seal 32 is removed before use, but the indicator 40 thereon can still indicate that the capsule 14 has been exposed to high temperature during storage / transport. When the seal 32 is removed, the indicator 40 is provided only around the rim 34 of the capsule 14. In other embodiments, the indicator 40 may be applied only to the rim 34 (e.g., to avoid waste of the indicator material).

[0133] Indicator 40 is annular or ring-shaped. The ring is substantially continuous. Indicator 40 is provided at the same or similar radial distance around its circumference from the center 62 of capsule 14 (e.g., indicator 40 is self-similar with respect to rotation). This allows the indicator to be read when the capsule is in any orientation in the heating chamber 10.

[0134] In some embodiments, capsule 14 may comprise one or more individual portions of indicator 40. If capsule 14 includes N-fold symmetry, at least N portions of indicator 40 can be provided. For example, since capsule 14 can be inserted in only a single orientation, a 1-fold symmetric capsule 14 requires only a single indicator portion 40.

[0135] It can be understood that indicator 40 may have any shape, size, or form. Indicator 40 may comprise a spot or patch. Indicator 40 may be applied directly to capsule 14. The indicator may be affixed to a label, sticker, or removable substrate. Indicator 40 may be provided at any suitable location (e.g., bottom wall 26 or side wall 28). Thus, the sensor may be provided on the side wall / bottom wall of heating chamber 10.

[0136] As shown in FIG. 18, indicator 40 is configured to change color upon application of heat to capsule 14 (i.e., when the temperature of capsule 14 changes). In some embodiments, the emitted wavelength and / or spectrum of indicator 40 can change in response to a change in temperature. For example, indicator 40 can change from blue to red, from white to green, from black to white, etc.

[0137] In some embodiments, the intensity (i.e., luminance) of the emitted light can change in response to a change in temperature. For example, at a first temperature, indicator 40 may be bright, and at a second temperature, indicator 40 may be dull. This can be provided by a change in the reflectivity and / or fluorescence of the pigment.

[0138] In some embodiments, the opacity / translucency of the indicator 40 may be configured to change in response to a change in temperature. For example, at a first temperature, the indicator 40 is transparent / translucent, and at a second temperature, the indicator 40 is opaque. In certain embodiments, the indicator 40 is configured to be transparent / translucent at ambient temperature (i.e., less than 40°C). The opacity of the indicator 40 may increase as the temperature rises. Thus, the indicator 40 is generally not visible to the user under ambient conditions. In an alternative specific embodiment, the indicator 40 is configured to be opaque at ambient temperature (i.e., less than 40°C). The opacity of the indicator 40 may decrease as the temperature rises.

[0139] The colored portion may be provided below the indicator 40. Thus, when the opacity of the indicator 40 changes, a change in the apparent color of the indicator 40 is observed. In some embodiments, the colored portion may include the color of the capsule 14 (e.g., its natural color or a coating thereon). Alternatively, the colored portion may be deposited on the capsule 14, and the indicator 40 is deposited on the colored portion.

[0140] In some embodiments, the indicator 40 may be configured to emit radiation in the non-visible spectrum (e.g., infrared / UV). The indicator 40 can emit invisible radiation at ambient temperature and / or during a temperature change. Thus, the indicator 40 cannot be visually recognized or does not change to be visually recognizable during heating of the capsule 14. Alternatively, the indicator 40 can emit visible light only during a temperature increase. Thus, the indicator 40 can only be seen after heating.

[0141] In some embodiments, the indicator 40 may be configured to emit radiation only in response to invisible radiation incident thereon. For example, the indicator 40 may be fluorescent. The indicator 40 may be fluorescent in response to UV light. Thus, the indicator may not be visible and / or may not emit light without using UV light.

[0142] When the indicator 40 responds to / emits invisible radiation, the sensor 42 may be configured to detect the invisible radiation and / or the lighting device may be configured to emit invisible radiation accordingly. The sensor may comprise a UV / IR sensor and the lighting device may comprise a UV / IR source (e.g., a UV / IR diode).

[0143] It can be understood that the sensor 42 is configured to detect changes in the wavelength, intensity, and / or spectrum of the radiation emitted by the indicator 40. Thus, a "color change" can be interpreted as a change in the wavelength, intensity, and / or spectrum of the radiation emitted by the indicator 40 accordingly.

[0144] In some embodiments, the indicator 40 is configured to gradually change color with a change in temperature (i.e., the color change is continuous). Thereby, the user can determine the temperature to which the capsule 14 has been exposed. For example, the user can determine that the temperature capsule 14 has been exposed by comparing the color of the indicator 40 with a calibration chart. In some embodiments, thereby, the device 2 can determine the current temperature of the capsule 14. This can provide feedback to the device 2, for example, to ensure that the device 2 is operating at the correct temperature. Alternatively, this can enable a visual inspection of the capsule 14 to allow for manual adjustments such as temperature.

[0145] In some embodiments, indicator 40 is configured to change color stepwise with a change in temperature (i.e., the color change is discrete / discontinuous). Indicator 40 may be configured to change color at a predetermined temperature. The predetermined temperature may be a temperature at which the smoking product irreversibly changes, thereby providing a sub-optimal smoking experience. Two or more predetermined temperatures may be provided. Thus, two or more discrete color changes can be provided accordingly. For example, the first color change may indicate that capsule 14 has been stored / transported above a first predetermined temperature. The first predetermined temperature may be about 60°C. The second color change may indicate that capsule 14 has been heated in device 2 above a second predetermined temperature. The second predetermined temperature may be about 100°C. Thus, indicator 40 can indicate that capsule 14 has been exposed to one or more different temperatures.

[0146] The color change may saturate (i.e., stop changing) at a predetermined temperature. This temperature can be determined according to the desired operating parameters of device 2 or the smoking product. For example, the color change may saturate at a temperature of 60°C or higher, preferably 100°C or higher, preferably 150°C or higher.

[0147] In some embodiments, the color change of indicator 40 may be irreversible. Thus, when indicator 40 changes from its original color to a new color, the indicator does not return to its original color even if the temperature returns to ambient temperature. This provides a permanent or semi-permanent indicator that capsule 14 has been exposed to high temperature. Thus, indicator 40 can provide an anti-tampering indicator 40.

[0148] In other embodiments, the color change of indicator 40 can be reversible. Thereby, the temperature of capsule 14 can be monitored during heating of capsule 14 (e.g., to provide feedback to device 2). The monitoring may be provided in real time.

[0149] In some embodiments, the indicator 40 is configured to indicate the freshness of the smoking product 30. The indicator 40 can 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 the oxidation of the smoking product 30. In some embodiments, the indicator 40 changes color in response to moisture and / or liquid.

[0150] In some embodiments, the hookah device 2 can read or communicate with the indicator 40 via an intermediate device 64. The intermediate device 64 is separate from / different from the hookah device 2. Typically, the intermediate device is an electronic or computing device, such as a fob, a touch screen device, a button / selector device, a mobile phone, a tablet computer, a laptop computer, etc. In some embodiments, the intermediate device may comprise a dedicated user / sensor interface device for use with the device 2, such as a reader or an NFC device.

[0151] The intermediate device 64 is connected to the hookah 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 and / or related to the indicator 40. And in this embodiment, the intermediate device 64 is wirelessly connected to the hookah device 2. Any suitable technology, such as Wifi, Bluetooth® (RTM), NFC, IrDA, etc. may be used. The intermediate device 64 and the hookah device 2 each comprise a wireless communication interface. The intermediate device 64 can comprise a remote device (i.e., it can operate in 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.

[0152] The hooking device 2 may be connected to the intermediate device 64 via an intermediate server or the like. For example, the device 2 can be connected to the intermediate device 64 via the Internet, or via a local network connection, or via a direct connection thereto.

[0153] The intermediate device 64 includes a sensor 66 configured to read / interrogate the indicator 40 of the capsule 14. The sensor 66 may be substantially the same as the aforementioned 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 of the indicator 40.

[0154] In some embodiments, the intermediate device 64 can simply transmit data from the indicator 40 to the hooking device 2, for example, without modification or using a verification indicator. The intermediate device 64 functions as a passing device or a relay device. The data from the indicator can be interpreted / processed by the hooking device 2. In a further example, the intermediate device 64 can modify, correct, or supplement the data of the indicator 40 or a part thereof. The intermediate device 64 can be used, for example, to implement user preferences or selections.

[0155] In some embodiments, the intermediate device 64 is configured to interpret / process the data from the indicator 40. The intermediate device 64 can extract one or more data portions (e.g., data fields) from the indicator data. Then, the data and / or the data portions can be stored in the memory of the intermediate device 64. The intermediate device 64 may include software (e.g., an app) configured to read / extract / process the indicator data.

[0156] The intermediate device preferably provides a user interface. The intermediate device 64 can present information regarding the capsule 14 to the user, for example, on a display. The information may comprise one or more of the extracted data parts / fields. For example, as shown in FIG. 19, the intermediate device 14 may show the flavor, authenticity, heating temperature / profile, and / or heat exposure indicator to the user. Thereby, the user can inspect and / or query the capsule 14 without inserting the capsule 14 into the hookah device 2.

[0157] The intermediate device 64 can transmit the indicator data and / or a part thereof to the hookah device 2. The data transmitted to the hookah device 4 can include all of the data or the extracted fields. Alternatively, the intermediate device 64 is configured to transmit only a part of the data or the extracted fields to the hookah device 2. In some examples, the selected part of the data / field is predetermined according to the operating parameters of the hookah device 2. For example, the hookah device 2 can operate effectively with only the heating temperature / profile being transmitted.

[0158] In embodiments having the intermediate device 64, the hookah device 2 may be further configured to read the indicator 40 as described above. Thus, the intermediate device 64 can be used with the hookah device 2, for example, to simply verify the contents of the capsule 14 before use or to correct the data directly read by the device from the indicator 40.

[0159] In some embodiments, the intermediate device 64 is configured to provide bidirectional communication with the hooking device 2. Thus, the hooking device 2 can transmit data to the intermediate device 64. The hooking device 2 can transmit indicator data and / or a part thereof to the intermediate device 64. The intermediate device 64 can display the indicator data and / or a part thereof. The hooking device 2 may transmit operation / heating information to the intermediate device 64. For example, the hooking device 2 can transmit sensor data (e.g., the temperature of the heater 10) to the intermediate device 64. The hooking device 2 may transmit status updates and / or error messages to the intermediate device 64. Thus, the intermediate device 64 can operate as an external display for the hooking device 64.

[0160] In an example of use, the capsule indicator data can include a plurality of different heating profiles in the capsule, and the intermediate device can be used to select one of the heating profiles for implementation by the device 2. The profiles can include, for example, gentle, normal, aggressive heating profiles for individual users, or different session durations. The profiles can include a "group" or "party" mode, whereby the device is intended to be used by multiple users who require different heating profiles than a single user.

[0161] FIG. 19B shows the use of an intermediate device 64 configured to communicate directly with (i.e., transmit data to) the indicator 40. The intermediate device 64 need not communicate directly with the device 2. The intermediate device can write to or modify the data of the indicator 40. This enables the customization / optimization of the date or instructions provided to the capsule 12 (e.g., heating profile, operating time, or rest time). In addition to or instead of this, the data transmitted from the intermediate device 64 to the indicator 40 may be further transmitted to a hookah device (e.g., when the capsule is inserted therein). This enables the upgrading or enhancement of the functions of the device 2 without the need for a connection to the public network (e.g., the Internet) of the device 2.

[0162] As described above, the indicator 40 can provide information / data regarding one or more parameters or characteristics of the capsule 14 and / or the smoking article 30. The indicator 40 can provide one or more of the following, among others:

[0163] · It can include data regarding one or more flavorants of the smoking article 30. This can include a wide range of qualitative indicators (e.g., "sweet" or "sour") and / or specific qualitative flavors (e.g., "strawberry" or "bubble gum").

[0164] · One or more components of the smoking article 30. This can include a list of all or part of the components (e.g., active ingredients). The list can include the weight / volume and / or the relative proportion of one or more components. One or more allergens can be indicated. The indicator 30 can indicate whether the smoking article 30 includes tobacco and / or nicotine-containing products.

[0165] · The composition or type of the smoking article 30. This can indicate whether the smoking article is in a general form, e.g., whether the smoking article 30 includes tobacco, inert beads, paste, and / or combinations thereof.

[0166] ·The quantity of the smoking product 30 (e.g., weight / volume) and / or the size of the capsule 14 (e.g., weight / volume / dimensions).

[0167] ·The heating temperature of the smoking product 30. This indicates the preferred or optimal temperature of the smoking product during heating to ensure an optimal smoking experience.

[0168] ·The heating profile and / or power profile of the smoking product 30. This indicates the preferred or optimal temperature-time dependent profile of the smoking product during heating to ensure an optimal smoking experience. This will be described in detail later.

[0169] ·A pause profile for determining the length and / or temperature of a pause event. The pause profile may be customized by the user. The pause profile can determine the length of each smoking session and / or provide the corresponding heating profile when the session is not paused.

[0170] ·Data regarding the manufacture or distribution of the capsule 14. For example, one or more of the batch number, manufacturing date and time, quality control marker, manufacturer identifier, supplier identifier, retailer identifier.

[0171] ·Data regarding the integrity of the smoking product 30 such as the expiration date, or the shelf life. This may be provided by a heat exposure indicator (e.g., a thermochromic pigment). In some embodiments, the hook device 2 can write data to the indicator 40 to indicate that the capsule 14 has been heated or used. Thus, the indicator 40 can comprise a marker or a flag.

[0172] · Data for authenticating the capsule 14. This enables the user to confirm that the capsule 14 is genuine. The authentication can include a unique code / cipher, hash, authentication token, and / or signature. This can be verified against a database of known codes (e.g., using an internet-connected database). In some embodiments, the data can include a self-verifying code / string. For example, the code can include one or more check digits or checksums.

[0173] · Usage restrictions. This may include age restrictions. For example, in this case, the smoking product 30 includes tobacco, alcohol, caffeine, or other age-restricted products. The age restriction can indicate a number (e.g., 16, 18, or 21) and / or be qualitative (e.g., "child", "adult", etc.). In some embodiments, the smoking product 30 and / or a specific capsule 14 can be associated with a specific user or class of users. For example, this can be used when the smoking product 30 contains other controlled ingredients such as prescription drugs or marijuana. The data can include a user ID. The data can include a user name and / or a unique code.

[0174] · Checksum. The checksum can be used to verify the data stored in the indicator 40 and / or a portion thereof.

[0175] It can be understood that the parameters may be stored as database fields, etc. Thus, the hooka device 2 and / or the intermediate 64 can extract and / or process any of the fields as described above.

[0176] The heating profile 68 of the capsule 14 and / or the smoking article 14 is shown in FIG. 20. The heating profile 68 defines the optimal or preferred heating temperature of the capsule 14 as a function of time. The heating profile 68 can be determined using any suitable method, as will be understood by those skilled in the art. Typically, the heating profile depends on one or more of the type / composition of the smoking article 30, the weight / volume of the smoking article 30, and / or the shape / size and / or thickness of the capsule wall.

[0177] In some embodiments, the heating profile 68 may be fixed or standardized for a particular smoking article 30 and / or capsule 14. Thus, each indicator 40 of the capsule 14 that houses the product 30 includes substantially the same heating profile data.

[0178] In other embodiments, the heating profile 68 can vary between different capsules 14 that house the same smoking article. This can allow for variations in the heating profile 68, for example, to account for variations in the manufacture of the smoking article 30 due to different temperatures, humidities, or starting materials. The smoking article 30 can be sampled periodically, and the heating profile 68 can be determined accordingly. The smoking article 30 may be sampled at predetermined intervals and / or between batches.

[0179] The temperature of the capsule 14 is generally controlled by controlling the temperature of the heater 10. Typically, the heat output of the heater 10 is controlled by varying the power therein. 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 may include a thermometer operably connected or engaged to the heater 10 and / or the capsule 14. The thermometer may include one or more of a thermocouple, an infrared thermometer, an electrical resistance thermometer, and the like. In some embodiments, the monitoring system can indicate the temperature using a color change of the capsule indicator 40.

[0180] The hookah device 2 may be configured to heat the capsule 14 at a plurality of different temperatures. Accordingly, 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 successive second temperature 72. The heating profile may be maintained at a given temperature for a predetermined period 74. The first temperature 70 is higher than the second temperature 72 in order to evenly heat the smoking product 30 in the capsule 14 to the desired temperature. During this time, the user may not smoke the hookah device 2. This provides an initial "warming-up stage". Next, the second temperature 72 can provide the temperature at which the user inhales the vaporized smoking product 30. This provides a "smoking stage".

[0181] The change between the first temperature 70 and the second temperature 72 may be instantaneous. Accordingly, the change / boundary between the first temperature 70 and the second temperature 72 is stepped or discontinuous.

[0182] The heating profile 68 may change continuously over a given period 76. For example, the heating profile 68 can steadily decrease over the period 76. This provides a "drop" in temperature to prevent the combustion of the smoking product 30 from depleting (i.e., the temperature is proportional to the remaining mass of the unconsumed smoking product 30).

[0183] In some embodiments, the hookah device 2 is configured to change the temperature of the heater 10 in response to the user's inhalation. Typically, the temperature rises to counteract the cooling effect of the incoming air. In addition to or instead of this, this increases the amount of vapor produced by the smoking product 30 to provide an improved smoking experience. This provides a preventive means of ensuring the quality of the smoking experience. The increase in temperature can provide an inhalation event 78 in the heating profile 68. Accordingly, the heating profile 68 only provides a baseline temperature of the heater 10, and that temperature can change in accordance with the user's inhalation.

[0184] The temperature increase may be at least 5°C, preferably at least 10°C, preferably at least 20°C. In addition or alternatively, the temperature during inhalation event 78 may include the absolute temperature. The absolute value may be stored in indicator 40. The increase in power to heater 10 may be at least 3%, preferably at least 5%, preferably at least 10.

[0185] Inhalation can be detected via an inhalation sensor. The sensor can comprise a pressure sensor, etc. The pressure sensor can include a resistive, capacitive and / or inductive pressure sensor. In addition or alternatively, the sensor comprises a mechanical air flow sensor. For example, the sensor may comprise a flap or diaphragm configured to move during inhalation. The flap / diaphragm may be connected to a potentiometer, etc. In addition or alternatively, the sensor comprises an accelerometer that measures the vibration of the system caused by the inhalation and formation of bubbles. The sensor may be disposed at any suitable location in the air passage between mouthpiece 22 and inlet opening 17, or outside the air passage. The inhalation sensor is operably connected to the heater controller to control the flow of power to heater 10.

[0186] In some embodiments, inhalation event 78 is configured to operate only during the inhalation period. Thus, the increase in power to heater 10 is provided only during inhalation. In some embodiments, inhalation event 78 is configured to operate over a predetermined period. Thus, the increase in power to heater 10 is provided over a predetermined period after inhalation is detected. The predetermined period may start at the start or end of the user's inhalation.

[0187] In some embodiments, the inhalation event 78 is configured to attempt to offset only the cooling effect of the intake air. Thus, the heater 10 attempts to maintain the temperature of the heating profile 68. The temperature loss during inhalation may be pre-calibrated. For example, if a 10°C drop is observed during inhalation in a calibration experiment, this value is stored in the device and the heater temperature is configured to increase by 10°C when an inhalation event is detected accordingly. Thus, the heating profile 68 is maintained. It can be understood that the cooling effect may be proportional to the inhalation rate. The device 2 may be configured to determine the intake air flow rate and adjust the temperature increase accordingly. Thus, the device 2 predicts the temperature drop of the heater 10 and adjusts the power to the heater 10 to at least partially offset the drop.

[0188] In some embodiments, the heater 10 is configured to adjust reactively to the user's inhalation. Thus, the device 2 can monitor the temperature of the heater 10. When the temperature drops during heating, the power to it increases. Thus, the heater 10 attempts to track the temperature of the heating profile 68. Such a configuration does not require a user of an inhalation sensor, but the smoking experience may not be sub-optimal.

[0189] The heating profile 68 can include any number of heating temperatures / levels. One or more temperatures may be repeated in the heating profile. Thus, the heating profile 68 may be periodic / wavy. The period 74 at each temperature can vary between temperatures. The boundaries / gradients can include any suitable gradient. The gradient can vary between different temperature boundaries / gradients. The heating profile 68 may change continuously and / or discontinuously. The heating profile 68 may be curved and / or include straight portions.

[0190] In the first embodiment, the general form (i.e., shape) of the heating profile 68 is stored in the hookah device 2. The hookah device 2 can store one or more heating profiles 68. The indicator 40 is configured to include data configured to modify a pre-stored / predetermined heating profile 68.

[0191] As shown in FIG. 21, in some embodiments, the indicator data includes a modifier configured to modify the temperature value, power value, and / or time value of the heating profile 68. For example, in the heating profile 68A, the modifier changes the temperature or output of the heating profile 68. The modifier may comprise a simple scalar modifier (e.g., the heating profile 68 is multiplied by a scalar value). In this example, the scalar modifier is >1, thereby increasing the temperature or output 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 a configuration provides a simple transformation of the heating profile 68 to meet the temperature requirements of the smoking product 30. The low-temperature smoking product 30 may have a relatively low modifier value, and vice versa.

[0192] In the heating profile 68B, the modifier changes the total period 80 of the profile 68. The modifier may comprise a simple scalar modifier. Such a configuration provides a simple transformation of the heating profile 68 to fit the quantity / size of the smoking product 30 and / or the capsule 14. The relatively low weight / volume of the smoking product 30 may have a relatively low modifier value, and vice versa.

[0193] In some embodiments, the modifier is configured to modify only a selected portion of the heating profile. The modifier can modify only the temperature / period 74 of a selected portion of the temperature level. For example, the modifier can modify only the temperature and / or period 74 of the warm-up phase and / or the smoking phase.

[0194] In some embodiments, the modifier may be configured to provide temperature and / or duration data for each phase. Thus, while the general form of the heating profile remains constant, the duration and temperature of each phase may vary independently. The modifier may be automatically applied by the device 2 when reading the capsule indicator 40, or may be manually selected by the user, for example using an intermediate device 64.

[0195] In some embodiments, the device 2 may store a plurality of different heating profiles 68. Thus, the indicator 40 may include an indication of the particular heating profile 68 required. Thus, the particular heating profile 68 is selected according to the inserted capsule 14 and / or smoking product 30. This makes it possible to provide a plurality of different heating profiles while retaining a minimum amount of data in the indicator 40.

[0196] [[ID=Z]] An example of the data structure of the indicator 40 is shown in FIG. 22. The data includes an identifier 82 for the smoking product 30 and / or capsule 14. The hookah device 2 can read / interpret the identifier 82 in order to identify the smoking product 30 / capsule 14 accordingly. The data includes a heating profile indicator 84 configured to indicate a particular heating profile 68 pre-recorded in the hookah device 2. Thus, when the data is read by the hookah device, the heating profile 68 is selected accordingly. The data in FIG. 22 includes only temperature and time, but embodiments of the present invention may also include power settings for the device / heater.

[0197] In some embodiments, the product / capsule identifier 82 may be associated with a particular heating profile 68 in the memory of the hookah device. Thus, the hookah device 2 automatically selects a heating profile according to the product / capsule identifier 82.

[0198] 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 can manually select the heating profile via a manual input (e.g., a button or a dial, etc.) of the brewer device 2 and / or can use the intermediate device 64.

[0199] The data may include a stage identifier 86. This identifies and / or depicts different stages (e.g., different temperatures or power levels). The data comprises a temperature indicator 88 indicating the desired temperature at each stage. The temperature indicator 88 can indicate a fixed temperature and / or a temperature gradient (e.g., the change in temperature per unit time). The data comprises a time interval indicator 90 indicating the desired time interval / period for each stage. The data can then include temperature and period data for each stage accordingly. Thus, the brewer device 2 can read the data at each stage and construct the heating profile 68. It can be understood that instead of providing temperature or period values, a temperature and / or period modifier may be provided.

[0200] Referring to FIG. 23, in some embodiments, the optimal / preferred heating profile 68 may be sampled at several points 92. As shown in FIG. 24, the sample points 92 can be stored in the indicator 40. The sample points 92 comprise a temperature and / or power indicator 96. The sample points 92 comprise a time indicator 98 corresponding to the temperature and / or power indicator 92. Thus, the sample points 92 provide coordinates and the like.

[0201] As shown in FIGS. 25A and 25B, the sample points can be processed by the hooking device 2 to provide a reconstructed heating profile 94. By providing specific data points or coordinates to the capsule indicator 30, the hooking device 2 can operate using only the input from the capsule 14. This reduces the need to store any pre-programmed profiles, etc. in the device 2. Thus, the device 2 can receive any appropriately formatted profile, at any level of complexity. This allows the heating profile to be changed or created during the capsule manufacturing / programming stage without the need to modify / update the device 2, providing a future-proof configuration. Thus, the hooking device 2 may comprise a "dumb" device into which the heating profile instructions are simply inserted.

[0202] In the embodiment shown in FIG. 25A, the hooking device 2 is configured to interpolate and / or extrapolate between the sample points 98. This provides a continuous heating profile 68. Thus, the heating profile can include a heating gradient. In the embodiment shown in FIG. 25B, the hooking device 2 need only change stepwise to the indicated temperature 96 at the indicated time 98. The temperature at each step remains substantially constant. Thus, the sample points 92 can provide the boundary points of several steps.

[0203] The power setting at each step can include the maximum / threshold power or substantially constant power at that step.

[0204] In this embodiment, the sample points 92 are provided only at the boundaries between different steps of the heating profile. Thus, the sample points 92 are provided only at the points where the heating profile 68 changes gradient (e.g., turning points or inflection points) and / or stepwise. This provides the minimum amount of sample points while generally providing an accurate / representative heating profile 68.

[0205] In some embodiments, the sample points 92 are provided at predetermined time intervals. For example, the sample points 92 may be provided at a predetermined interval. This can be beneficial when the heating profile 68 is complex. When the sample points are provided at a predetermined interval, the predetermined interval can be pre-programmed into the hookah device 2, so the time indicator 98 need not be provided in the indicator data. In addition to or instead of this, the indicator data can specify a predetermined time interval, and accordingly, the hookah device 2 constructs a heating profile.

[0206] As shown in FIG. 26, the heating profile 68 may be smoothed. This provides a continuous and / or stepless heating profile 68. This can be achieved by applying a smoothing algorithm to the heating profile 68. The heater 10 then heats the capsule 14 according to the smoothed heating profile. In addition to or instead of this, the heater 10 may be configured to smoothly heat the capsule 14 regardless of the heating profile 68. For example, the heater 10 may be controlled using a PID controller. This prevents overshoot and / or fluctuations such as the desired temperature.

[0207] It can be understood that the heating profile 68 only provides the desired heating temperature. In reality, the actual temperature achieved can vary for several reasons, such as thermal lag, feedback / sensor lag, user inhalation, air temperature, and / or other unexpected thermal variations. Therefore, the heater 10 is configured to continuously adapt its temperature to reach the specified heating profile 68. The actual temperature can oscillate around and / or towards the desired temperature.

[0208] In some embodiments, the indicator 40 can include a plurality of heating profiles 68. The heating profiles 68 can be modified according to one or more usage conditions. For example, a user may desire 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 "mellow" 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 smoke required for more users. The user can select any such change using the intermediate device 64 as described above. The heating profile can vary according to one or more of: · Smoke intensity · Smoking time; · Number of users; · Number of pauses permitted in a session, time permitted for each pause, or total pause time; · Display of capsules or combinations thereof used in a multi-capsule session (i.e., when stacked as described above) It can be understood that it can be changed according to one or more of the above.

[0209] The duration, output, and / or temperature of each stage of the heating profile and / or inhalation temperature can be varied according to usage conditions. Depending on the usage situation, the overall shape (i.e., the relative temperature of each stage) can be made different. A finite number of heating profiles 68 can be provided according to the individual selection by the user. For example, the user can select "high", "medium", or "low". Also, the heating profile can be variable according to any scale. For example, the user can select a value between 1 and 10.

[0210] It can be understood that the heating profile 68 and / or the corresponding time / temperature values provided in the accompanying drawings described above are arbitrary and are only used to illustrate the present invention at hand. The heating profile 68 and the corresponding data can take or be recorded in any suitable form.

[0211] In the above embodiment, the parameters related to the capsule 14 and / or the smoking product 30 are stored in the indicator 40. Then, the indicator 40 is read / checked by the hookah device 2, and the parameters are processed accordingly. This configuration is schematically shown in FIG. 27. It can be seen that the capsule / product parameter 100 is read / checked by the hardware / software 102 of the hookah device 2. The hardware / software 102 may include programmable logic (e.g., FPGA) and / or firmware, etc. The hardware / software generally includes a "low-level" system / language. Then, the parameter 100 is processed by the executable code 104 arranged in the hardware / software 102. The executable code 104 is stored in the memory of the hookah device 2. The executable code 104 generally includes a "high-level" system / language. The executable code 104 can process the parameter 100.

[0212] The executable code 104 and / or the device software 102 (e.g., firmware) may be changeable and / or replaceable (i.e., the memory is rewritable). Thereby, for example, the hookah device 2 can be updated to provide additional or different heating profiles, etc. The hookah device 2 may be connectable to the Internet and / or may be configured to receive code updates from the intermediate device 64.

[0213] In an alternative embodiment shown in FIG. 28, the executable code 104 is configured to be stored in the indicator 40. Thus, the indicator 40 comprises high-level executable code. The hookah device 2 is configured to read / interrogate the indicator 40 and extract the executable code 104 therefrom. The executable code 104 may be stored in the memory of the hookah device 2. The executable code 104 is then executable by the hookah device 2. The parameter 100 can be extracted from the indicator 40 and processed by the executable code 104.

[0214] The executable code 104 is stored in the indicator 40 such that the executable code 104 is accessible from an external device. For example, the executable code 104 is stored in a part of the memory accessible from the external device. In addition to or instead of this, the indicator 40 may be configured to send an executable file when queried (e.g., when the indicator 40 is an NFC device). The code may include open text / plain text or may be encrypted.

[0215] The executable code 104 may be stored permanently or persistently in the hooking device 2. Thereby, the hooking device 2 can be updated with new executable code.

[0216] In some embodiments, the executable code 104 may be stored in the hooking device 2 in a semi-permanent or temporary manner. For example, the executable code 104 may be replaced when the hooking device 2 reads / queries a new indicator. Thus, the executable code 104 can be adjusted according to each capsule 14 and / or smoking product 30. For example, thereby, the heating profile 68 can be customized. In addition to or instead of this, thereby, the hooking device 2 may be enabled to provide functions that were not previously possible with the existing executable code 104.

[0217] In some embodiments, the executable code 104 may be removed after a predetermined period. In some embodiments, the executable code 104 may be removed when the power to the hooking device is removed (e.g., the executable code may be stored in non-volatile RAM). In some embodiments, the executable code 104 may be removed in response to the heating cycle completing and / or removing the capsule 14 from the hooking device 2.

[0218] In some embodiments, when the executable code 104 is not provided (e.g., the code 104 has been erased), the hooking device 2 is configured not to function. For example, the hooking device 2 may not activate the heater 10. This prevents unauthorized use or tampering of the hooking device 2. For example, this can prevent the hooking device 2 from operating with the capsule 14 inserted. When the executable code 104 is not provided, the hooking device 2 generally comprises only a low-level system. Such a low-level system can provide only basic functions such as reading / querying the indicator 40, for example. The hooking device 2 may provide a "dam" system. Thus, the system can listen / wait for instructions from the indicator 40 of the capsule 14 and / or via the intermediate device 64.

[0219] A method of operating the hooking device will be described with reference to FIG. 29. In a first step 106, the capsule 14 is inserted into the hooking device 2. The capsule 14 is placed in the heating chamber 10. The capsule 14 is in close contact with the heating chamber 10 to ensure good thermal contact with the heating chamber 10. Then, the lid 12 is closed to cover the capsule 14, enclosing the capsule in the heating chamber 10. The lid 12 can engage and / or seal the capsule 14. Power to the hooking device 2 may be provided before and / or after insertion of the capsule.

[0220] In the next step 108, the hooking device 2 reads / queries the indicator 40. The hooking device 2 extracts and / or processes the data of the indicator 40 as described above. This may be performed directly by the hooking device 2 and / or via the intermediate device 64. The hooking device 2 may be configured to periodically read / check / examine the indicator 40 to detect its presence.

[0221] In some embodiments, the hook device 2 is configured to send an authentication code / token to the indicator 40. The indicator 40 then interprets the authentication code and determines that the code is genuine. If the code is considered genuine / valid, the indicator 40 can initiate and / or permit further communication with the hook device (i.e., send data). If the code is not considered genuine / valid, further communication is prevented. Thereafter, communication can be blocked until a valid authentication code is sent by the hook device 2. This prevents unauthorized investigation or extraction of data from the indicator 40 and ensures its integrity.

[0222] The authentication code can take any suitable form and / or use any suitable technique, as described above with reference to the capsule authentication code. The authentication code can include an Advanced Encryption Standard (AES) code / cipher.

[0223] In the next step 110, the hook device 2 verifies the integrity of the capsule 14 and / or the smoking product 30. This can take several forms, for example:

[0224] · One or more of verification of the authentication code / signature can be taken. The hook device 2 comprises an algorithm for processing the authentication code to determine whether the code is genuine. The algorithm can include a hash algorithm. The hook device 2 may be configured to provide a time delay during each verification process. For example, if one capsule 14 is inserted into the hook device 2, verified, removed, and then a second capsule 14 is inserted, the second verification process for the second capsule 14 is only initiated after a time delay. The time delay can be 0.1 seconds or more, preferably 1 s or more, preferably 1 s or more, preferably 2 seconds or more. This can help prevent reverse engineering of the verification code by a brute force attack. In some embodiments, the delay can be 30 seconds or more.

[0225] · Determine whether the capsule 14 has been exposed to an undesirable temperature, for example, by determining the color of a thermochromic indicator · Determine whether the smoking product is within / outside its expiration date · Determine whether the capsule 14 is properly positioned in the heating chamber 10 (e.g., whether the indicator 40 is properly readable / queryable) · Determine whether the type / size / weight of the smoking product 30 is suitable for use with the hookah device 2 · Determine whether usage restrictions are met. The hookah device 2 and / or the intermediate device 64 can include a record of user qualification information. For example, the user profile is stored in the hookah device 2 and / or the intermediate device 64. The system verifies whether the user's age and / or ID matches the qualification information of the user profile · Verify the data checksum. If the checksum fails, the reading / querying of the indicator 40 is performed again

[0226] If the hookah device 2 determines that the capsule 14 and / or the smoking product 30 does not meet the required integrity and / or limit parameters, the hookah device 2 can 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 not meeting the integrity parameters. For example, an "authentication failed" or "already heated capsule" message can be provided. The notification may be provided as an error code, etc. The notification may be provided by a visual indicator (e.g., LED or visual display) of the hookah device 2. The notification may be provided directly to the hookah device 2 and / or via the intermediate device 4

[0227] In the next step 114, the hook device 2 is configured to discharge the capsule 14. This can be done automatically or manually. The hook device 2 comprises a discharge mechanism configured to discharge the capsule 14 from the heating chamber 10 accordingly. The lid 12 may be configured to open as part of the capsule release (for example, the lid 12 and the discharge mechanism may be operably connected via a linkage mechanism or the like). In addition to or instead of this, a notification for the user to manually remove the capsule 14 is provided.

[0228] It can be understood that the above verification step 110 may be performed by the intermediate device 64. The intermediate device 64 can send a signal to the hook device 2 to indicate that the integrity check has been successful and / or failed.

[0229] If the hook device 2 determines that the capsule 14 and / or the smoking product 30 do not meet the required integrity parameters, the hook device 2 can prevent the start of the heating profile loading step 116. The heating profile 68 is extracted from and processed based on the data of the indicator 40. The heating profile 68 can be loaded into the memory of the hook device 2.

[0230] In an embodiment where the thermochromic indicator 40 is provided, an initial heating step 118 may be provided. This initial step heats the capsule 14 to a predetermined temperature. Typically, the predetermined temperature is above the maximum temperature at which the smoking product 30 maintains its integrity (i.e., the temperature at which the smoking product 30 is irreversibly damaged). The predetermined temperature is typically lower than the heating profile temperature to prevent potential undesirable off-gases from non-certified products. The predetermined temperature may be 50 °C or higher, preferably 60 °C or higher. The predetermined temperature may be 120 °C or lower, preferably 100 °C or lower. The capsule 14 may be heated at the predetermined temperature for a predetermined period. The predetermined period may be 1 to 10 minutes, preferably 2 to 8 minutes.

[0231] In the next step 120, the color of the thermochromic indicator is determined during and / or after the heating step 118. The change in color (or lack thereof) is determined by the hookah device 2. The change in color can determine whether the capsule has been previously exposed. For example, if no change in color is measured, the capsule 14 may have been exposed to excessive heating during transportation / storage. If the capsule 14 is considered to have been exposed to excessive heating, the hookah device 2 can initiate the end routine 112. The hookah device 2 may accordingly provide a notification.

[0232] If the capsule 14 is considered not to have been exposed to excessive heating and / or in embodiments where no thermochromic indicator is provided, the hookah device 2 can initiate the heating step 122. In this step 122, the heater 10 heats the capsule according to a predetermined heating profile 68. The user can then inhale / smoke the smoking product 30 as needed.

[0233] During the heating step 122, the hookah device 2 is configured to monitor for a "pause" event 124. The pause event 124 is configured to indicate that the user wishes to pause use of the device for a period of time. During the pause event 124, the heater 10 can reduce its temperature. Accordingly, the power to the heater 10 can be reduced. In some embodiments, the temperature may only partially decrease. For example, if the heater is configured to operate at a normal state of 180 °C, during the pause event, the heater 10 can operate at 100 °C. The pause temperature may be 80% or less, preferably 60% or less, preferably 50% or less of the normal temperature.

[0234] In other embodiments, the temperature decreases to ambient temperature. Accordingly, the power to the heater 10 may be zero. This can prevent excessive combustion of the smoking product 30.

[0235] When the pause event 124 is detected, the temperature of the heater 10 decreases. The pause event can continue until the "resume" event 126 is triggered. The resume event 126 indicates that the brewer device 2 continues to heat the capsule 14 according to the heating profile 68. Therefore, the pause event 124 can continue indefinitely.

[0236] In some embodiments, the pause event 124 may be configured to extend over a predetermined period. When the predetermined time has elapsed, the brewer device 2 may continue the heating step 122. The user can select and / or define one or more periods. For example, options to pause heating for 1 minute, 5 minutes, or 20 minutes can be provided. Each option can include its own input (e.g., a button).

[0237] The pause / resume event is generally initiated by the user. The pause / resume event may be initiated by manual input to the brewer device 2 (e.g., a button / dial, etc.) and / or via the intermediate device 64.

[0238] During operation, the brewer device 2 is configured to monitor the position of the lid 12. The brewer device 2 is configured to monitor whether the lid 12 is provided in the closed position and / or the open position. A sensor is provided to determine the position of the lid. The sensor can comprise optical and mechanical sensors (e.g., contact / pressure sensors, etc.). When the lid 12 is detected to be in the open position, the brewer device 2 is configured to initiate an end routine 112. Therefore, the heater 10 is configured to stop in response to the opening of the lid 12. The capsule 14 can then be ejected. This can prevent overheating of the brewer device 2.

[0239] In other embodiments, when the lid 12 is detected to be in the open position, the hookah device 2 is configured to initiate a pause event. Thus, the heater 10 can partially reduce or stop the temperature. Next, the hookah device 2 can resume the heating stage 122 when the lid 12 is provided in the closed position. Thus, the opening of the lid 12 only pauses the heating cycle.

[0240] Generally, when the lid 12 is open (i.e., heating is stopped / prevented), the device 2 may not operate or may not start. In some embodiments, the device may be configured to shut down if the lid 12 is not returned to the closed position within a predetermined period. For example, the predetermined period can preferably include 1 second, 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 an active smoking session does not exceed the total period defined by the indicator 40. An active smoking session is defined as the period during which the lid 12 of the device is closed and / or the device is not paused.

[0241] In addition to or instead of this, the hookah device 2 is configured to monitor the position of the capsule 14. Thus, when the capsule 14 is at least partially removed, the hookah device 2 can initiate the end routine 112 and / or a pause event as described above.

[0242] The hookah device 2 continues to heat the capsule 14 according to the heating profile 68. When the heating cycle is complete, the hookah device 2 initiates the end routine 112. Thus, the heating of the capsule 14 stops after a predetermined period. This can help prevent the capsule 14 from overheating (e.g., if the user forgets to deactivate the device) and / or ensure that the smoking experience is consistent throughout the heating cycle. The capsule 14 is ejected when the heating cycle is complete. This can help indicate to the user that the capsule 14 should be removed.

[0243] When the capsule 14 is sufficiently cooled, the capsule 14 can be discharged. Thus, the capsule 14 remains in the device 2 even after a smoking session, preventing exposure to hot surfaces. In some embodiments, the capsule 14 may be discharged after a predetermined period. In addition to or instead of this, the capsule 14 is discharged when the capsule 14 reaches a predetermined position. For example, when the capsule 14 and / or the heating chamber 10 reach a temperature below 100 °C, preferably below 75 °C, preferably below 50 °C, the capsule 14 can be discharged. In other embodiments, the capsule may remain in the device until manually removed at the end of the heating cycle.

[0244] A user can be provided with a notification of the completion and / or start of the end routine 112. In some embodiments, the progress of the heating cycle (i.e., the progress through the heating profile) can be provided. The progress indicator can indicate the percentage 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 that 40 minutes of smoking remains. The notification may be provided at one or more selected points during the progress. The notification may be provided periodically. For example, the notification may be provided every 10% of the progress change or every 10 minutes. In addition to or instead of this, the notification may be provided at a selected progress point. For example, the notification can be made when only 15 minutes of smoking time remains. This notification may be made in the hookah device 2. For example, the hookah device 2 may be provided with a progress indicator. In addition to or instead of this, the indicator may be provided in the intermediate device 64. In some embodiments, the indicator (e.g., an LED, etc.) can indicate that the heating cycle is approaching completion and / or has been completed.

[0245] When the end routine is started (112), and / or when the removal of the capsule 14 during / after the heating stage 122 is detected, the authentication code of the capsule 14 is recorded by the hook device 2. Since each authentication code is unique, the hook 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., higher than the temperature at 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.

[0246] In some embodiments, the authentication code may be stored only when the capsule 14 is heated for a predetermined period. The predetermined period may be the time during which the smoking product can irreversibly change. The predetermined period 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 depleted). This allows the capsule 14 to be used over several sessions. The period may be at least 50%, preferably at least 75%, preferably at least 90% of the total smoking time until the product is depleted.

[0247] The hook device 2 may store each authenticated code in a memory. The authentication code may be transmitted to a remote database (e.g., via the Internet and / or an intermediate device 64). During the verification stage 110, the hook device 2 compares the authentication code of the capsule 14 with the authentication codes of the used capsules 14 held in the memory / database. If the hook device 2 determines that the authentication code of the current capsule 14 matches the authentication code of a used capsule, the end routine 112 may be started. Thus, the hook device 2 determines whether a given capsule 14 has been previously heated by the hook device 2 and selectively prevents the heating of the capsule 14 if such conditions are met. Conversely, if the hook device 2 determines that the authentication code of the present capsule 14 does not correspond to the authentication code of a used capsule 14, the heating cycle is started. This prevents the heating of empty, aged, and / or reused capsules 14.

[0248] 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 may be configured to undergo melting, combustion, decomposition, pyrolysis, vaporization and / or a change in form / phase. The indicator 40 may be configured to be destroyed due to its inherent properties. For example, the heating temperature is higher than the melting / combustion temperature of the indicator 40 and / or its important components. In addition to or instead of this, the indicator 40 can include a predetermined failure point configured to be destroyed at a predetermined temperature. For example, the indicator 40 includes a fuse configured to melt / burn during heating, and thus the indicator 40 can be made operable. When the indicator 40 is destroyed, when reinserted into the hook device 2, the reading step 108 and / or the integrity step 110 fails, thereby preventing the reuse of the capsule 14. In some embodiments, the indicator 40 may be physically or partially destroyed by removing the indicator from the capsule 14. For example, the indicator 40 may be configured to peel off during removal and / or may be fragile.

[0249] In some embodiments, the hook device 2 and / or the mobile device 64 are configured to initiate a "kill" routine. The kill routine is configured to render the indicator 40 at least partially inoperable to prevent its reuse. In some embodiments, the device 2 may be configured to erase at least a portion of the memory of the indicator 30. The device 2 can delete any portion of the indicator 30 memory required for normal operation during the integrity check step 110 described above. In some embodiments, the device 2 can write a flag or other signal to the indicator 30 memory to indicate that the capsule has been used / invalid.

[0250] In some embodiments, indicator 30 is configured to delete at least a portion of its memory upon receiving a code or signal. For example, the hook device 2 and / or the portable device 64 may be configured to transmit a “kill” signal or code. Upon receiving the code, indicator 30 deletes all or at least a portion of the indicator memory. 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 indicator 30.

[0251] Referring now to FIG. 30, the memory 128 of indicator 30 is operably divided into two portions. The first portion 130 provides a “public” memory section. The public section 130 is accessible without authentication. Thus, the public section 130 can be accessed by any device suitable for examining indicator 30. For example, the mobile device 64 can read / interrogate the public section 130 of the memory.

[0252] The second portion 132 provides a “private” section. The private section 132 is accessible only via authentication. The authentication can be provided as described above. Thus, only an authenticated device can access the private memory 132. This ensures that only a specific device can access the private section, and thus the integrity of the data is ensured.

[0253] The public part 130 can include general data or public data. For example, the ID of the capsule 14 or the name / flavor ID may be arranged in the public part 130. Thereby, any device can identify the content of the capsule 14. Conversely, the private part 132 includes private data or confidential data and should therefore be read only by an authorized device. For example, the private part 132 includes one or more heating profiles 68, manufacturing data, and / or private data (i.e., data that can be subject to privacy regulations).

[0254] The public part 130 may be a rewritable memory. Therefore, the user can write data to the public part 130. The user can specify their usage situation and record the usage situation in the public part 130. For example, the user can use the mobile device 64 to record the desired intensity in the capsule memory 128. Then, the hookah device 128 can read the user's preference and select an appropriate heating profile accordingly. The user can record the number of users or other user preferences.

[0255] The public part 130 can record the usage data of the capsule 14. The usage data can include the time the capsule 14 was heated, the remaining time until the product runs out, or the percentage of the consumed product 30. Thereby, it can show the user how much of the smoking product 30 remains. The usage data may be read by the hookah device 2, thereby enabling the continuation of a previous heating session (i.e., the heat profile 68 is resumed). Therefore, the capsule 14 acts as an intermediate for facilitating communication between the hookah device 2 and the mobile device 64.

[0256] In some embodiments, the data of the indicator 40 (i.e., its public and / or private parts) may be rewritable. For example, the hookah device 2 can format the data of the indicator and / or add a read count (i.e., the number of times the hookah device has read / queried the memory).

[0257] The smoking product 30 may comprise any suitable form or composition. The smoking product comprises a "mist maker". The mist maker is configured to generate a cloud when vaporized. The mist maker includes a volatile material configured to provide a light-scattering cloud in a vaporized state. The mist maker includes a polyol. The polyol may include one or more of glycerin; 1,2-propylene glycol; 1,3-propylene glycol; 1,2-butylene glycol; 1,3-butylene glycol; 1,4-butylene glycol; 2,3-butylene glycol; 1,2,4-butanetriol; triethylene glycol; triacetin; mannitol; sorbitol; xylitol; inositol; isosorbide; polydextrose; or dianhydro-D-glucitol. The polyol may include a "sugar alcohol" (hydrogenated sugar).

[0258] The product may contain a sweetener. The sweetener may include a carbohydrate sweetener (e.g., monosaccharides with 5 or 6 carbon atoms), such as arabinose, xylose; ribose; glucose; mannose; galactose, fructose; dextrose; or sorbose, among others. The sweetener may include disaccharides, such as sucrose, e.g., cane sugar or beet sugar, lactose; maltose; or cellobiose, among others. The sweetener may include polysaccharides, such as partially hydrolyzed starch or dextrin; polyols such as sorbitol, mannitol, xylitol; and mixtures of one or more of the above sugars. The sweetener may include a glycoconjugate / carbohydrate mixture (e.g., natural sugar products). The sweetener may include one or more of molasses; invert syrup; corn (maize) syrup; maple syrup; golden syrup; treacle, etc.

[0259] In some embodiments, the sweetener includes high fructose corn syrup (also known as glucose - fructose isoglucose and glucose - fructose syrup).

[0260] In some embodiments, the sweetener includes an artificial sweetener. The artificial sweetener may include one or more of sodium, calcium or ammonium saccharin salts; dihydrochalcones; rebaudioside; mogroside; glycyrrhizin; dipotassium glycyrrhizinate; ammonium glycyrrhizinate salt; L - aspartyl - L - phenylalanine methyl ester (aspartame); sodium or potassium salt of 3,4 - dihydro - 6 - methyl - 1,2,3 - oxathiazin - 4 - one - 2,2 - dioxide (acesulfame - K); extract of Stevia rebaudiana (stevioside); extract of Richardella dulcifica (miracle berry); extract of Dioscoreophyllum cumminsii (Serendipity Berry).

[0261] It can be understood that any of the above sweeteners may be combined with any of the other above sweeteners or classes of sweeteners.

[0262] The product contains flavoring agents. The flavoring agents can include, inter alia, mint; for example, peppermint and spearmint; chocolate; liquids; citrus and other fruit flavors; gamma-octalactone; vanillin; ethyl vanillin; or one or more of the flavors of mouth fresheners. The aforementioned sweeteners may include examples of flavoring agents, but typically both sweeteners and additional flavoring agents are provided.

[0263] The flavoring agents can include one or more of spices, such as cinnamon; methyl salicylate; linalool; bergamot oil; geranium oil; lemon oil; or ginger oil. The flavoring agents can include plant extracts or essential oils. The flavoring agents can include one or more of food-based flavoring agents, such as apple flavoring; blueberry flavor; coconut flavoring; grape flavoring; guava flavor; pomegranate flavoring; or lemon flavoring. The flavoring agents may include fruit or plant flavorings. The flavoring agents can include one or more of acids; alcohols; esters; aldehydes; ketones; or pyrazines.

[0264] The product, such as its flavoring agents, can include stimulants. The stimulants have a stimulating effect on the central nervous system and can induce wakefulness in a subject. The stimulants can include one or more of caffeine (1,3,7-trimethylxanthine); taurine (2-aminoethanesulfonic acid); theobromine (3,7-dimethylxanthine); or derivatives thereof.

[0265] In some embodiments, the stimulant is provided by a plant-based extract that forms part of the flavorant. The plant extract may include one or more of coffee; black tea; green tea; matcha; yerba mate; kola nut; cocoa; ginseng; guarana; or cannabinoids such as tetrahydrocannabinol (THC) or cannabidiol (CBD). In other embodiments, the stimulant may include an additive provided in addition to the flavorant. For example, a coffee flavorant may be fortified with additional caffeine.

[0266] The product may include a colorant. The colorant can provide a colored product 30 and / or smoke. The colorant includes colorants that are safe for food, pharmaceuticals, or cosmetics. The colorant includes water-soluble colorants. The colorant includes plant-based colorants, such as beet juice; brazilwood; caramel; carminic acid; litmus; wood; fruit trees; or saffron. In some embodiments, the colorant includes artificial colorants.

[0267] In certain embodiments, the smoking product includes shisha or mu'assel. Shisha includes tobacco. The tobacco may be shredded or otherwise micronized. The tobacco is mixed with a sweetener (e.g., molasses) and a mist maker (e.g., glycol). Accordingly, the shisha is provided as a viscous semi-solid. In some embodiments, the shisha may not include tobacco. The shisha may include a nicotine additive and / or substitute. The shisha may include a tobacco substitute. The tobacco substitute may include an organic by-state. In some examples, the smoking product may include marijuana, cannabis, or other substances derived from hemp in addition to or instead of tobacco or a tobacco substitute product.

[0268] In some embodiments, the smoking product may be provided on an inert substrate. The substrate includes an inert or food-safe material. The inert material is configured not to melt, burn, decompose, or degrade when exposed to heat. For example, the inert material is temperature stable up to at least 200°C; at least 300°C; or at least 300°C.

[0269] The inert substrate may include an inorganic or mineral material. In some embodiments, the inert material includes a non-crystalline amorphous material such as glass. The glass may include silica (SiO2)-based glass.

[0272] In some embodiments, the inert filler may include sand or granules (e.g., crushed microparticles or microparticles). The sand may include one or more of the above materials. The average particle size of the granules is such that the filler has a granular / sandy consistency and does not form a suspension in air like finer microparticles such as powders and dust. This can reduce the health risks associated with fine powders. In certain embodiments, the substrate includes stone; glass; ceramic; pumice or sand.

[0273] The product may be provided on the surface of a substrate (e.g., providing a coating on the substrate). The substrate can provide a core. The coating can substantially cover the entire surface of the substrate and thus maximize the surface area of the product. The coating can include a uniform thickness across the surface of the substrate. The substrate can include rounded / spherical shapes. Thus, the product and the substrate define a bead-like configuration.

[0274] In some embodiments, the smoking product may be provided as a plurality of particles. The particles can be granular and / or powdery. The particles can be sticky or prone to aggregation.

[0275] In certain embodiments, the shisha product includes a substrate. The substrate may include the aforementioned inert material. The substrate includes microparticles (e.g., beads, etc.). The beads are aligned to form a layer configuration. In some embodiments, the substrate may include a smoking product. The smoking product may be provided as a coating and / or layer of the substrate.

[0276] The shisha product may be compressed onto the substrate. Thus, the substrate is at least partially embedded in the shisha product.

Similarly, the indicator 30 can provide any suitable information regarding the smoking product 30, as described above.

[0278] In some embodiments, the capsule 14 can be used to contain products that are not typically used for smoking. The products can include products configured to be heated. Thus, the capsule 14 can provide a heating profile 68 for the product. The products can include one or more of beverages or precursors for their manufacture, such as coffee; tea; hot chocolate; soft drinks (e.g., syrups), etc. The products can include one or more of mixed beverage compositions, such as espresso; latte; cappuccino; mocha, etc.

[0279] This configuration allows the hookah device to heat the smoking product according to a heating profile. This allows for complex variations in the heating temperature of the smoking product, thereby providing the user with an optimal smoking experience. The profile can be provided in a simple and data - efficient manner. The profile can cause the heater to stop when the product is depleted and / or the smoking session is complete.

[0280] The indicator allows for determination of the reliability and / or integrity of the smoking product. The indicator can provide an indicator that shows the smoking product has been exposed to excessive temperatures. The indicator can provide further information regarding the smoking product, thereby allowing the hookah device to adapt its operation according to the smoking product. For example, the indicator can allow the hookah device to automatically determine the heating profile of the smoking product.

[0281] The heating cycle routine prevents the heater from operating when the capsule is not provided and / or when the lid is open. This improves the safety of the device. The hookah device can be easily updated to provide improved software functionality.
