This application is related to U.S. Patent Application Publication No. 2015 / 0320116, filed May 12, 2015, the disclosure of which is hereby incorporated by reference in its entirety.
[0002] The present invention generally relates to systems, devices, products, apparatuses, and methods used for detecting temperature within an induction heating system, and in particular embodiments, to devices, systems, and methods for detecting temperature within an induction heating system of a vaporizer device.
Background Art
[0003] Induction heating involves heating an electrically conductive object (e.g., a metallic body) by electromagnetic induction. For example, induction heating can include heating the object based on heat generated within the object by eddy currents flowing within the object. In some cases, an induction heating system can include an induction heating element and an electrically conductive object that is heated based on electromagnetic induction. The induction heating element can include an electromagnet and an electronic oscillator that passes an alternating current (AC) through the electromagnet so that the electromagnet can generate a magnetic field. The magnetic field can be directed towards the electrically conductive object, and the magnetic field can penetrate the electrically conductive object. Based on the magnetic field, a current can be generated within the electrically conductive object. This current can be referred to as an eddy current. The eddy current can flow through the electrically conductive object and generate heat within the electrically conductive object based on Joule heating. In some cases, the electrically conductive object can include a ferromagnetic material (e.g., iron) and can generate heat within the electrically conductive object based on magnetic hysteresis (e.g., magnetic hysteresis loss).
[0004] In some cases, the conductive object may include a susceptor. The susceptor may be a material having the ability to absorb electromagnetic energy and convert the electromagnetic energy into heat. In some examples, the susceptor may be designed to emit the heat as radiation (e.g., infrared thermal radiation). The electromagnetic energy may include radiation (e.g., electromagnetic radiation) in the RF (radio frequency) spectrum or the microwave spectrum.

However, it must be understood that the invention may assume various alternative variations and step sequences, unless specifically specified to the contrary. It must also be understood that the specific devices and processes shown in the attached drawings and described in the following specification are merely exemplary embodiments or aspects of the invention. Accordingly, the specific dimensions and other physical characteristics relating to the embodiments disclosed herein and aspects of such embodiments should not be considered as limiting, unless otherwise indicated.
[0070] As used herein, aspects, components, elements, structures, acts, steps, functions, instructions, etc. should not be considered important or essential unless explicitly described as such. Also, as used herein, the articles "a" and "an" are intended to include one or more units and may be used interchangeably with "one or more" and "at least one". Further, as used herein, the term "set" is intended to include one or more units (e.g., related units, unrelated units, combinations of related and unrelated units, etc.) and may be used interchangeably with "one or more" and "at least one".

Further, the expression "based on" is intended to mean "based at least partially on" unless otherwise explicitly stated.
[0071] In some non-limiting embodiments, an induction heating system may include an induction heating element and a susceptor. The induction heating system may be used to heat an object in thermal contact with the susceptor (e.g., adjacent to the susceptor so that the susceptor can heat the object, in contact with the susceptor so that the susceptor can heat the object, etc.). For example, a vaporizer device may include the induction heating system, and the induction heating system may be used to heat a material (e.g., an organic material, a synthetic material, etc.) in thermal contact with the susceptor. In some non-limiting embodiments, the temperature of the susceptor may be controlled based on measuring the temperature of the susceptor. In some non-limiting embodiments, the temperature of the susceptor may be controlled such that the chemical composition of the vapor generated by the material heated by the induction heating system is within a desired chemical composition range.
[0072] However, detecting the temperature of the susceptor by a device such as a thermocouple, a silicon sensor chip, and / or an infrared radiation thermometer may be difficult due to the size of the susceptor and / or the size of the device used to measure the temperature of the susceptor. For example, in a vaporizer device, the induction heating system may be small, and due to the size of a device such as a thermocouple, a silicon sensor chip, and / or an infrared radiation thermometer, the device may be prevented from being used to detect the temperature of the susceptor because the device cannot be in thermal contact with the susceptor. Further, the device may not be able to withstand being in thermal contact with the susceptor and the temperature of the susceptor. In addition, the device may not be able to accurately detect the temperature of the susceptor because the device cannot be in thermal contact with the susceptor.
[0073] Non-limiting embodiments of the present invention are directed to devices, systems, and methods for sensing temperature within an induction heating system. In some non-limiting embodiments, the system includes an induction element, a susceptor element, and a temperature sensor circuit in thermal contact with the susceptor element.

Further, a resonance frequency of the temperature sensor circuit varies based on the temperature of the susceptor, and the induction element is electromagnetically coupled to the temperature sensor. Further, the resonance frequency of the temperature sensor circuit is equal to 1 / 2π√LC.
[0074] In this way, embodiments of the present invention enable accurate sensing of the temperature of the susceptor element based on the temperature sensor circuit of the system being in thermal contact with the susceptor element. Further, the temperature sensor circuit of the system can withstand the temperature of the susceptor based on the temperature sensor including a capacitor and an inductor.

Additionally or alternatively, a hardware circuitry may be used instead of or in combination with the software instructions to execute one or more processes described herein. Thus, the embodiments described herein are not limited to a particular combination of hardware circuitry and software.
[0093] The number and arrangement of the components shown in FIG. 2 are provided as an example. In some non-limiting embodiments, device 200 may include additional components, fewer components, different components, or components arranged differently than those shown in FIG. 2. Additionally or alternatively, a set of components of device 200 (e.g., one or more components) may execute one or more functions described as being performed by another set of components of device 200.
[0094] Referring now to FIG. 3, FIG. 3 is a flowchart of a non-limiting embodiment of process 300 for detecting temperature within an induction heating system. In some non-limiting embodiments, one or more of the steps of process 300 may be performed (e.g., fully, partially, etc.) by control device 114. In some non-limiting embodiments, one or more of the steps of process 300 may be performed by a device or group of devices separate from control device 114 or including control device 114.
[0095] As shown in FIG. 3, at step 302, process 300 includes heating the susceptor element based on the current induced in the susceptor element. For example, an induction heating element (e.g., induction element 112) may provide a magnetic field (e.g., induction magnetic field, magnetic field, etc.) received by susceptor element 108. Susceptor element 108 may generate heat within the susceptor element based on the current generated within the susceptor element based on the magnetic field being received by the susceptor element 108.
[0096] In some non-limiting embodiments, the induction heating element may be driven by power supply 116. For example, the induction heating element may receive current from power supply 116 based on control device 114 controlling the induction heating element and / or power supply 116. In some non-limiting embodiments, control device 114 may cause the induction heating element to provide a magnetic field to susceptor element 108. For example, control device 114 may provide a control signal to the induction heating element, and the induction heating element may provide the magnetic field to susceptor element 108 based on the control signal from control device 114.
[0097] Still referring to FIG. 3, at step 304, process 300 includes determining the resonant frequency of a temperature sensor circuit associated with the susceptor element based on heating the susceptor element. For example, control device 114 may determine the resonant frequency of temperature sensor 102 associated with susceptor element 108 when susceptor element 108 generates heat.
[0098] In some non - limiting embodiments, the control device 114 may determine the resonance frequency of the temperature sensor 102 based on the capacitor 104 and the inductor 106. For example, the control device 114 may determine the resonance frequency of the temperature sensor 102 based on the formula 1 / 2π√LC, where in the above formula, L is the inductance value of the inductor 106 and C is the capacitance value of the capacitor 104. In some non - limiting embodiments, the control device 114 may determine the resonance frequency of the temperature sensor 102 based on the magnetic field provided by the inductor 106 and received by the induction element 112. For example, the control device 114 may cause the induction element 112 to provide a first magnetic field to the temperature sensor 102, and the first magnetic field is received by the inductor 106. The inductor 106 may provide a second magnetic field based on receiving the first magnetic field from the induction element 112. The induction element 112 may receive the second magnetic field from the inductor 106. The control device 114 may determine the resonance frequency of the temperature sensor 102 based on the second magnetic field provided by the inductor 106 and received by the induction element 112. In some non - limiting embodiments, the second magnetic field may include a component of the first magnetic field having a frequency different from that of the first magnetic field.
[0099] Further, as shown in FIG. 3, at step 308, process 300 includes determining the temperature of the susceptor element based on the resonant frequency of the temperature sensor circuit. For example, control device 114 may determine the temperature of susceptor element 108 based on the resonant frequency of temperature sensor 102. In some non-limiting embodiments, control device 114 may determine the temperature of susceptor element 108 based on a change in the resonant frequency of temperature sensor 102. For example, when susceptor element 108 is heated by an induction heating element, control device 114 may determine a first resonant frequency of temperature sensor 102 based on a first magnetic field provided by the induction heating element. When susceptor element 108 is heated by the induction heating element based on a second magnetic field provided by the induction heating element, control device 114 may determine a second resonant frequency of temperature sensor 102. Control device 114 may compare the first resonant frequency and the second resonant frequency to determine the temperature of susceptor element 108 based on a change in the resonant frequency of temperature sensor 102 from the first resonant frequency to the second resonant frequency.
[0100] In some non-limiting embodiments, the resonant frequency of temperature sensor 102 may change based on a change in the capacitance value of capacitor 104. For example, when susceptor element 108 is heated, the temperature of capacitor 104 of temperature sensor 102 may increase. Based on the increase in the temperature of capacitor 104, the capacitance value of capacitor 104 may decrease.
[0101] Figures 4A through 4C are diagrams of a non-limiting embodiment of a vaporizer device 400 having an induction heating system. Figures 4A and 4B show an assembled view of the vaporizer device 400, and Figure 4C shows an exploded view of the vaporizer device 400. As shown in Figure 4A, the vaporizer device 400 may include a housing 402. For purposes of illustration, Figure 4B depicts the vaporizer device 400 with the housing 402 being transparent. As shown in Figure 4B, the vaporizer device 400 may include an induction heating assembly 420, a housing 402, a power source 416, and a tube 444. As shown in Figure 4C, the vaporizer device 400 may include an electronic control component 436, at least one activation button 438, an induction heating assembly 420, a cartridge 418, a housing 402, a power source 416, a valve 442, a tube 444, and a mouthpiece component 446.
[0102] In some non-limiting embodiments, the induction heating assembly 420 may include a chassis 448 (e.g., an internal frame for supporting components of the induction heating assembly 420), an induction heating element 412 (e.g., an induction coil), and / or a heating element body 440. For example, the heating element body 440 may be sized and / or configured to hold the induction heating element 412 when the induction heating element 412 is disposed within the heating element body 440. Additionally or alternatively, the chassis 448 may be sized and / or configured to hold the induction heating element 412 and the heating element body 440 in proximity to the electronic control component 436, and may enable control of the induction heating element 412 by the compact-sized electronic control component 436. Additionally or alternatively, the heating element body 440 may function as a heat insulator against the heat generated by induction heating of a susceptor element (e.g., a wick element, a wick, etc.) within the cartridge 418, and may shield electronic components from the radiation of electromagnetic energy generated by the induction heating element 412.
[0103] In some non-limiting embodiments, the cartridge 418 may be sized and / or configured to fit within the inductive heating element 412 and may enable a compact structure of the vaporizer device 400. The cartridge 418 may have a hole at one end that allows vapor or aerosol from the vaporizable substance to flow out of the cartridge 418. In some non-limiting embodiments, the cartridge 418 may be configured to have a reservoir, and the reservoir may be structured to hold the vaporizable substance. The susceptor element may be configured to be contained within the reservoir, and the susceptor element may contact the vaporizable substance of the reservoir. The inductive heating element 412 may be configured to be housed within the heating element body 440. The inductive heating element 412 may be inductively coupled to the susceptor element within the cartridge 418 such that the susceptor element is heated by electromagnetic induction through heat generated within the susceptor element by eddy currents.
[0104] In some non-limiting embodiments, the cartridge 418 may be an exchangeable and / or disposable container for the vaporizer device 400. For example, the cartridge 418 may contain a predetermined amount of the vaporizable substance, and when the vaporizable substance is used up or nearly used up, the user may replace the cartridge 418 (e.g., with another cartridge). By way of example, the vaporizable substance may be any composition, material, or substance that produces a vapor for human inhalation when heated to a predetermined temperature. In some non-limiting embodiments, the vaporizer device 400 may include an indicator of the amount of vaporizable substance remaining in the cartridge. For example, the indicator may be present on the cartridge of the vaporizer device 400 and / or on the housing. In some non-limiting embodiments, the indicator may include a digital or analog output screen that is visible to the user and is present on the vaporizer device 400. In some non-limiting embodiments, the vaporizer device 400 may have a second indicator that indicates when the cartridge 418 is nearing empty and functions as a low-level indicator for the vaporizable substance.
[0105] In some non-limiting embodiments, the cartridge 418 can be configured to be refilled with a vaporizable substance. Additionally or alternatively, the cartridge 418 can be configured to be refilled while being present within the vaporizer device 400, such as by passing through a hole or opening in the housing 402. In some non-limiting embodiments, the inductive heating element 412 (e.g., an induction coil) can be formed as a replaceable cartridge component such that the cartridge structure (e.g., the body of the cartridge, the susceptor element, and the induction coil) can be designed to be replaced. For example, such a replaceable cartridge can include an electrical connection for connecting the induction coil to other electronic control components.
[0106] In some non-limiting embodiments, the replacement of the cartridge 418 can be achieved by removing the housing 402 and separating any additional desired components. In some non-limiting embodiments, the replacement of the cartridge 418 can be achieved without removing the housing 402. For example, the vaporizer device 400 can allow the user to remove an empty cartridge 418 and replace the empty cartridge 418 with a new filled cartridge 418 within the inductive heating assembly 420 without removing any components. In some non-limiting embodiments, the vaporizer device 400 can include a channel or chamber defined in the vaporizer device 400 that allows for the removal of an empty or nearly empty cartridge 418 and accepts a replacement cartridge 418. In some non-limiting embodiments, the vaporizer device 400 can include a channel or chamber that can be operated (e.g., folded, twisted, etc.) to open to receive a new cartridge 418 and then closed and operated to position the cartridge 418 appropriately (e.g., to allow heating of the vaporizable substance within the cartridge 418). In some non-limiting embodiments, the housing 402 can have a chamber or channel defined in the vaporizer device 400, and the housing 402 can be configured to receive the cartridge 418 within the chamber or channel.
[0107] In some non-limiting embodiments, the susceptor element may be present within the cartridge 418, and the susceptor element may be heated inductively even without an electrical connection to the power source 416. Additionally or alternatively, the cartridge 418 may include a body having an inner surface, and the susceptor element may be disposed adjacent to the inner surface of the cartridge 418. Additionally or alternatively, the body and / or neck of the cartridge 418 may function as a heat insulating member between the susceptor element and the induction heating assembly 420. For example, such a heat insulating member may remove (e.g., separate) the induction heating assembly 420 (e.g., induction coil) from contact with the vaporizable substance (e.g., liquid) within the cartridge 418. In some non-limiting embodiments, the cartridge 418 may be made of a suitable heat insulating material including, but not limited to, glass, fiberglass, ceramic, etc. In some non-limiting embodiments, the open end of the cartridge 418 may define an air passage through the vaporizer device 400.
[0108] In some non-limiting embodiments, the activation button 438 may be configured to protrude through an opening in the housing 402 such that, for example, a user may activate the vaporizer device 400. Additionally or alternatively, the activation button 438 may be configured such that physical button pressing is not required. For example, the activation button 438 may include a touch screen component such as a capacitive touch screen. Additionally or alternatively, by using such a touch screen, a user may interact with the vaporizer device 400 to view and / or verify information such as age, number of uses, and other analytical information. Additionally or alternatively, the capabilities of such a touch screen may be combined with internal sensors to form a smart vaporizer that may be connected for communication and networked to a local computer or the Internet.
[0109] In some non-limiting embodiments, the activation button 438 can be integrated with another aspect and / or component of the vaporizer device 400. For example, the activation button 438 can be integrated with the mouthpiece component 446. For purposes of illustration, contact of the mouthpiece component 446 by the user's mouth can enable activation of the vaporizer device 400 (e.g., function as the activation button 438). Additionally or alternatively, the activation button 438 can include a biometric device (e.g., fingerprint scanner) and / or another form of identification device for identifying the user. For example, the user can personalize the vaporizer device 400 and / or prevent others from using the vaporizer device 400. For purposes of illustration, such features can be useful in situations where monitoring of the vaporizer device 400 is not always available and / or can prevent unauthorized users (e.g., children) from using the device.
[0110] In some non-limiting embodiments, the housing 402 can be sized and / or configured to substantially house, i.e., enclose, the components of the device so as to provide an appearance for the vaporizer device 400 and / or be ergonomically shaped to fit the user's hand. In some non-limiting embodiments, the housing 402 can include an upper housing 402a and a lower housing 402b. For example, the upper housing 402a and the lower housing 402b can be structured to have an aesthetically pleasing appearance (e.g., mimic a wood-grain appearance) and / or can include colors, shapes, markings, etc., as desired. In some non-limiting embodiments, the upper housing 402a and the lower housing 402b can be interchangeable to allow the user to customize a particular appearance of the vaporizer device 400.
[0111] In some non-limiting embodiments, the housing 402 can be made from any suitable material such as wood, metal, fiberglass, plastic, etc. In some non-limiting embodiments, the mouthpiece component 446 can be replaceable. For example, a variation of the mouthpiece component 446 can be designed such that the mouthpiece component 446 can restrict the air flow to reproduce a suction feeling that is more preferable and / or familiar to the user with respect to smoking, such as a cigarette, cigar, pipe, etc. In some non-limiting embodiments, the activation button 438 can include, for example, one or more control buttons, sensors, or switches that enable the user to interact with the vaporizer device 400. In some non-limiting embodiments, the simplest interaction of the activation button 438 can be to turn the vaporizer device on and off.
[0112] In some non-limiting embodiments, the susceptor element can be configured to heat a substance adjacent to and / or in contact with the material of the susceptor element. For example, based on the inductive heating of the susceptor element by the inductive heating assembly 420, the vaporizable substance can be heated. In some non-limiting embodiments, the susceptor element can be configured to move the vaporizable substance from the reservoir based on capillary action of the susceptor element. In some non-limiting embodiments, the vaporizable substance can be a liquid and / or viscous substance, and as the liquid is vaporized, more liquid can move upward through the susceptor element.
[0113] In some non-limiting embodiments, the configuration of the susceptor element can be a twisted wire, a twisted rope-like material, a mesh, a mesh tube, a plurality of concentric mesh tubes, a cloth, a plurality of sheet-like materials, a foam (or other porous solid) having sufficient porosity, a roll of fine metal mesh, or a metal foil, any other arrangement of fibers or mesh, and / or any other shape that is sized and / or configured to perform a wicking action by capillary action. Additionally or alternatively, the susceptor element can further include fins, protrusions, or other details that can be configured to hold a solid or semi-solid material in contact with the susceptor element.
[0114] In some non-limiting embodiments, the susceptor element can be structured from a combination of materials to obtain an appropriate effect. For example, the susceptor element can be a cloth (or other closely mixed combination) that weaves thin induction heating wires, twisted wires, and / or threads with wires, twisted wires, and / or threads that are wicked by capillary action. Additionally or alternatively, the materials of the susceptor element can be combined in the form of a rope or a foam, or can be thin sheet-like materials appropriately arranged. In some non-limiting embodiments, the susceptor element can include wound alternating material foils. Additionally or alternatively, the susceptor element can be surrounded (e.g., partially, completely, etc.) by an induction heating element 412 (e.g., an induction coil), and the induction heating element 412 does not necessarily have to be in contact with the mesh. In some non-limiting embodiments, since the susceptor element can be formed from a mesh, the mesh wick can be made from a material (e.g., FeCrAl alloy) that is efficiently heated by induction. In some non-limiting embodiments, the mesh wick can be formed using a Kanthal mesh. Additionally or alternatively, the susceptor element can be removable from the cartridge 418 such that the susceptor element can be cleaned, reused, and / or replaced separately from the cartridge 418.
[0115] In some non-limiting embodiments, the material used in the susceptor element may include a magnetic material and / or a metal conductor. Additionally or alternatively, the susceptor element may include a material that generates eddy currents and / or magnetic hysteresis when the susceptor element is exposed to electromagnetic energy from an electromagnetic field. For example, a magnetic material and / or a metal conductor material having significant hysteresis within the electromagnetic field may be employed with the vaporizer device 400. In some non-limiting embodiments, the susceptor element may include a material that is heated by both eddy currents and the movement of magnetic walls. In some non-limiting embodiments, the susceptor element may be iron. In some non-limiting embodiments, the susceptor element may include a ceramic magnet such as ferrite. In some non-limiting embodiments, the susceptor element may include a metal conductor that becomes hot by eddy currents. In some non-limiting embodiments, the susceptor element may include a semiconductor.
[0116] In some non-limiting embodiments, the valve 442 can be configured to control the air flow and / or seal the reservoir when the vaporizer device 400 is not in use. In some non-limiting embodiments, the valve 442 can be sized and / or configured to fit onto one end of a cartridge 418 having an opening. Additionally or alternatively, the valve 442 can have a shape that enables accurate attachment to the cartridge 418 and / or is sized and / or configured to contact and / or rest on an end of the induction heating element 412 (e.g., induction coil) for placing the cartridge 418 within the induction heating element 412. In some non-limiting embodiments, the cartridge 418 can be entirely within the induction heating element 412, or only a portion of the cartridge 418 can be within the induction heating element 412. In some non-limiting embodiments, the valve 442 can be electronically controlled and configured to remain closed until the vaporizer device 400 is activated by a user (e.g., through the activation button 438). In some non-limiting embodiments, the valve 442 can be manually controlled by threads and / or ramps in the mouthpiece. For example, the threads and / or ramps can control the gap between the valve 442 and the top of the cartridge 418. In some non-limiting embodiments, the valve 442 can be made from any suitable material such as plastic, rubber, fiberglass, metal, glass, etc. In some non-limiting embodiments, the valve 442 can be made from a suitable grade of silicone rubber.
[0117] In some non-limiting embodiments, the tube 444 may be disposed on one end of the valve 442 distal from the cartridge 418 and / or sized and / or configured to discharge the vapor and / or aerosol from the vaporizable substance from the mouthpiece component 446. In some non-limiting embodiments, the tube 444 may be cylindrical. In some non-limiting embodiments, the tube 444 may be formed from any suitable material including, but not limited to, glass. In some non-limiting embodiments, the tube 444 may be configured to cooperate with the valve 442 to regulate the air flow into and / or out of the vaporizer device 400 and / or to prevent leakage of the vaporizable substance when closed.
[0118] In some non-limiting embodiments, power may be provided from the power source 416 to the inductive heating element 412. In some non-limiting embodiments, the power source 416 may be in any form of a device that converts stored chemical energy into electrical energy. Additionally or alternatively, the power source 416 may be sized to fit the application (e.g., installation within the vaporizer device 400). In some non-limiting embodiments, the power source 416 may be a battery. For example, the battery may be a primary battery, a secondary battery, a rechargeable battery, etc. Additionally or alternatively, the battery may include an alkaline battery, a button cell, a lithium ion battery, etc.
[0119] In some non-limiting embodiments, the electronic components of the vaporizer device 400 (e.g., the electronic control component 436) may include a circuit including a current generating device, a processor, and at least one sensor. Additionally or alternatively, the power supplied to the inductive heating element 412 (e.g., an induction coil) may be controlled by the processor, and the processor may provide accurate monitoring and / or control of the power supplied to the inductive heating element 412 on a time scale that can be as small as a few milliseconds. In some non-limiting embodiments, the processor may be configured to receive information from the sensor and / or may be able to adjust the heating profile applied to the susceptor element by the inductive heating element 412. In some non-limiting embodiments, the sensor may be able to detect and / or calculate information such as the air flow from or to the vaporizer device 400, the pressure at a location within the vaporizer device 400 or the pressure of the vapor exiting the vaporizer device 400, the temperature of the induction coil, or the temperature at a location near or of a component of the vaporizer device 400. For example, such features may enable the circuit to detect that the power level can be increased to compensate for the user of the vaporizer device 400 starting to inhale and / or the incoming air tending to cool the susceptor element (e.g., below the ideal temperature, operating temperature range, etc. of the susceptor element). In some non-limiting embodiments, when active inhalation is not in progress, the circuit may then be able to reduce the power, which may improve the life of the power source 416.
[0120] In some non-limiting embodiments, the processor may be able to use the information to calculate and / or implement a temperature profile (e.g., an optimal temperature profile, etc.). Additionally or alternatively, the processor may be configured to adjust a heating profile applied to the susceptor element by the induction heating element 412 based on the vaporizable substance. For example, the processor may be able to implement a predetermined heating profile according to the vaporizable substance. In some non-limiting embodiments, the processor may enable the user to modify settings and / or entire algorithms for providing the heat to obtain an improved experience (e.g., a more preferable experience, the best experience, etc.). In some non-limiting embodiments, the design and / or configuration of all of the electronic components (e.g., the electronic control component 436, etc.) may be sufficiently energy efficient to enable the vaporizer device 400 to be handheld and battery-powered. Additionally or alternatively, the electronic components may include a printed circuit board, and in some non-limiting embodiments, the processor may include a microprocessor, a microcontroller, etc.
[0121] In some non-limiting embodiments, the cartridge 418 may include an identifier that includes content information regarding the contents of the cartridge 418. For example, the identifier may be incorporated into the cartridge 418 as, for example, a barcode, or as another mechanism that may provide a signal regarding the vaporizable substance and / or the susceptor element within the cartridge 418. In some non-limiting embodiments, the processor may be coupled to the induction heating element 412 and / or programmed to read the content information of the cartridge 418 to set parameters and cause the induction heating element 412 to apply a heating profile to the vaporizable substance according to the content information of the cartridge 418.

As shown in FIG. 5, the cartridge assembly 500 includes a temperature sensor 502, a susceptor element 508, and a cartridge 518. In some non-limiting embodiments, the temperature sensor 502 may be the same as or similar to the temperature sensor 102. In some non-limiting embodiments, the susceptor element 508 may be the same as or similar to the susceptor element 108. In some non-limiting embodiments, the cartridge 518 may be the same as or similar to the cartridge 418.
