The present disclosure relates generally to what are called e-cigarettes, vaporizers, or “vapes” in common parlance. These are devices that produce an aerosol of a material to be inhaled. The present disclosure relates more particularly to the use of induction heating to produce an aerosol.
To vaporize liquids, such as e-liquids (nicotine-containing, sometimes-flavored liquids used in e-cigarettes as replacements for cigarettes) and liquids containing herbal extracts, for inhalation by a user, the liquid must be raised to a suitable temperature while the user draws air past the heated liquid. The current prevalent technology consists of a reservoir of liquid from which a wick, typically made from glass fiber or stainless steel mesh, wicks the liquid into a heating coil, typically made from the FeCrAl alloy Kanthal, which is heated by passing a current through the coil.
The current approach suffers from several disadvantages. First, the temperature of the heater coil is necessarily higher than the temperature ideally required to vaporize liquid in the wick. This temperature difference can result in unwanted chemical reactions taking place at this hotter surface of the heater coil when sufficient heat is available to achieve the desired vaporization of liquid in the bulk of the wick. The unwanted chemical reactions can detrimentally effect both the quality of the experience by influencing the flavor and the health impact by increasing the presence of toxic chemicals. Second, the proximity of the coil to the liquid means any electrical conductivity of the liquid effects the functioning of the vaporizer. Third, the practical design of the reservoir and wick often results in leaks. Thus, there is a need for an improved vaporizer device.
This present disclosure provides systems and methods designed and configured to apply induction-heating in a vaporizer device to reduce the range of temperatures in contact with a liquid at the time of vaporization, designed and configured to separate the electrical paths from the air and liquid, and designed and configured to provide precise and rapid control of heating.
Disclosed herein is a vaporizer device that comprises a combined wick and heating element where the wick is inductively heated. Among other advantages, using induction heating allows the heat to be more evenly distributed through the volume of the liquid to be vaporized and thus to achieve the same or better rates of vapor production with lower temperature gradients and hence lower peak temperatures or hot spots.
Wicking is a process of moving liquids by the action of surface tension. The underlying physical process is similar for capillary action. For the wick to draw up the liquid so that it may be simultaneously heated and exposed to an air path to be drawn out as an aerosol mist, which may also be called a vapor, the wick may be a finely divided solid material. The wicking or capillary action relies on a reduction in the surface energy of the two separate surfaces—the liquid surface and the solid surface—when compared to the two surfaces in contact. The wicking or capillary action includes an effect that depends on the radius of curvature of both the liquid surface and the solid surface and hence there may be a need for large surface areas and small radii of curvature both of which are achieved by a finely divided material. The radius of curvature of the solid surface is important since as the liquid wets the solid, conformation of the liquid surface is largely determined by the solid. Another way of expressing the reduction in energy when the two materials are in contact vs. separate, is that the contact angle of a drop of the liquid placed on a flat surface of the wick material must be less than 90 degrees. As an example, when a capillary is placed in liquid mercury, the contact angle is greater than 90 degrees and the liquid level goes down, not up, which is the reverse of wicking.
With this in mind, in one embodiment, a combination wick and inductively heated element may be constructed of one material that performs both functions of wicking and heating. An alternating current of an appropriate frequency in the induction coil induces eddy currents and/or magnetic hysteresis heating of the wick element, causing the wick element to heat up. The wick material itself is a source of heat to the vaporizable substance rather than being indirectly heated by a resistively heated coil as in some current e-cigarette designs. According to embodiments, the material of the wick element may have the following properties: a sufficiently small contact angle with a liquid to be vaporized; be susceptible to induction heating so that the required temperature may be reached; and be finely divided enough to transport the liquid within the wick material and when the liquid is heated, create a vapor that is satisfying to the user.
According to embodiments, a vaporizer device as disclosed herein may have two modes of operation. One mode of operation is to heat loose leaf material where the induction heating element acts as a simple heater. In the other mode of operation the induction heating element, which acts as an absorber according to a wicking action, operates to vaporize waxes or liquids. The latter mode of operation is a combination of induction heating and wicking where one structure provides the wicking action and the heating simultaneously. In one embodiment, the induction heating element is a mesh of one material that fulfills both functions but the induction heating element may also be formed of more than one material and is a more intimate mixture of materials than simply wrapping a heating coil around a wick.
A vaporizer device, as disclosed, herein may have the ability to vaporize a number of different materials. An example of such a material is what has been referred to as “e-liquid”, which consists of varying proportions of propylene glycol and glycerine, and may or may not contain nicotine and flavors. For some people these devices can be a healthier replacement for smoking cigarettes. According to embodiments, a vaporizer device as disclosed herein may have the ability to vaporize a number of different materials from the same device with or without a simple exchange of a coil and the material to be vaped itself. Thus one device may be capable of vaping dry leaf material, waxes and e-liquids in the same device.
According to embodiments, a vaporizer device as disclosed herein may have the use of exchangeable cartridges that are self-contained with the vaping material, also called a vaporizable substance, and an induction wick element. Such cartridges may also be encoded with information that allows the device to sense information that allows the vaping conditions to be set specifically for that material. Induction provides a unique opportunity to use these self-contained cartridges by separating the heating from electrical contact. Accordingly, where the wick element is located in a cartridge, there is no need for electrical connections to a power source since the wick element is heated via induction and the cartridge is independent of the electronic components that require a power source such as a battery.
According to embodiments, a vaporizer device as disclosed herein may have a microprocessor on the device. Accordingly, the vaporizer device may have the ability to precisely control heating of the vaporizable substance. Further, according to embodiments, feedback information, such as pressure of the vapor exiting/entering the device and/or temperature of the heating component, may be used to optimize the vaping experience for a user. The use of feedback information may give the same experience for a user as the user inhales, puff after puff, irrespective of the recent history. In one embodiment, a heating pulse shape, according to temperature versus time, at heater of the vaporizer device may start at a high power to get up to temperature but then reduces to an optimal power before the temperature overshoots. This can reduce the need to have the heating element at an idle state while the device is in active use. In one embodiment, a heater of the vaporizer device may be controlled by the processor according to a control loop function. In another embodiment, the induction heating element of the vaporizer device may be controlled by the processor according to a predictive operation. In a predictive operation, instead of using a direct feedback of the temperature to adjust the power to maintain that temperature of the heater, a calculation may be performed based on a current temperature and a predetermined model of the behavior. A power level is then set that will achieve close to a desired temperature without the requirement for tracking it in real time. Accordingly, the power needed for each inhalation is determined and the processor controls the heater to use that amount of power.
Advantages of the present disclosure include:

It will be understood by those skilled in the art, however, that the embodiments may be practiced without such specific details. In other instances, well-known operations, components, and elements have not been described in detail so as not to obscure the embodiments described in the specification. Those of ordinary skill in the art will understand that the embodiments described and illustrated herein are non-limiting examples, and thus it can be appreciated that the specific structural and functional details disclosed herein may be representative and do not necessarily limit the scope of the embodiments, the scope of which is defined solely by the appended claims.
As disclosed herein, a vaporizer or vaporizer device includes such devices as electronic cigarettes (e-cig or e-cigarette), personal vaporizers (PV), electronic nicotine delivery systems (ENDS), and similar devices that produce an effect that is much like smoking tobacco. As discussed herein an induction heating system comprises a susceptor material, which is the material to be heated by the induction process, and an induction coil which generates a magnetic field to induce eddy currents in the susceptor material when the induction coil is powered. A coil is a practical geometry for the use in induction heating. While any AC magnetic field (i.e. around any conductor anywhere carrying AC) will cause some inductive heating, a coil geometry makes efficient use of that field. In embodiments described herein, an induction coil may have a cylindrical shape. In additional embodiments, the induction coil is not cylindrical, but instead has a square or spherical shape in implementation.
The induction element assembly 105 comprises an internal frame or chassis 119, an induction heating element 121, such as an induction coil, and a heating element body 123. As shown in the embodiment of
The cartridge 107 is sized and configured to fit within the induction coil 121, which allows for compact construction of the vaporizer device 100. The cartridge 107 has an aperture 125 in one end that allows the vapor or aerosol from the vaporizable substance to flow out of the cartridge 107. In embodiments, the cartridge is configured with a reservoir and the reservoir is structured to hold a vaporizable substance. A wick element is configured to be contained within the reservoir and the wick element contacts the vaporizable substance of the reservoir, the wick element is described in detail with regard to
Additionally, in embodiments, the cartridge 107 may be a replaceable and/or disposable container for the vaporizer device. In one embodiment, the cartridge may contain a predetermined amount of a vaporizable substance and when the vaporizable is used up or near to be used up, a user may replace with the cartridge. The vaporizable substance may be any composition, material, or matter that produces a vapor for inhalation by a human being when heated to a predetermined temperature. In one embodiment, the vaporizer device may comprise an indicator of the amount of vaporizable substance remaining in a cartridge. The indicator may be located on the cartridge or on the housing of the vaporizer device. The indicator may include a digital or analog output screen located on the vaporizer device that is visible to a user.
Furthermore, the vaporizable device may have a second indicator that indicates when the cartridge is close to empty and acts as a low volume indicator for the vaporizable substance. Additionally, in one embodiment, the cartridge may be configured to be refilled with a vaporizable substance. Further, the cartridge may be configured to be refilled while located within the vaporizer device such as through a vent or aperture in the housing. Additionally, in embodiments, an induction coil may be formed as part of a replaceable cartridge such that a cartridge structure (the cartridge body, the wick element, and the induction coil) is designed to be replaced. Such a replaceable cartridge would include electrical connections to connect the induction coil to other electronic control components.
In one embodiment, replacement of the cartridge may be accomplished by removing the housing and separating any additional components as necessary. In another embodiment, removal of the housing may not necessary. In one embodiment, the vaporizable device may allow a user to remove an empty cartridge and to replace it with a new, full cartridge within the induction element assembly without removing any components. In one embodiment, the vaporizer device may comprise a channel or chamber defined therein that allows for removal of an empty or near empty cartridge and accepts a replacement cartridge. In another embodiment, the vaporizer device comprises a chamber or channel that folds, twits, or is otherwise manipulated open to accept a new cartridge and then is manipulated to close and place the cartridge in the appropriate position to enable heating of the vaporizable substance within the cartridge. In another embodiment, the housing may have a chamber or channel defined therein and the housing is configured to receive the cartridge within the chamber or channel.
In addition, in embodiments where the wick element is located within the cartridge, there is no need for electrical connections to a power source since the wick element is heated via induction. Additionally, the cartridge may comprise a body having an inside surface and the wick element may be positioned adjacent to the inside surface of the cartridge. The neck or body of the cartridge may act as an insulating member between the wick element and the induction heating element. The insulating member removes the induction coil from contact with the vaporizable substance in the cartridge, such as a liquid. The cartridge may be made of an appropriate insulating material such as glass, fiberglass, ceramic, etc. According to embodiments, the open end of the cartridge defines an air path through the vaporizer device.
According to embodiment shown in
In addition, in another embodiment, the activation button 103 may be integrated with another aspect of the vaporizer device 100. For instance, the activation button 103 may be integrated with the mouthpiece component 117 such that, contact with a user's mouth to the mouthpiece component 117 may allow for activation of the vaporizer device 100. In addition, the activation button 103 may comprise a fingerprint scanner, or other form of identification device for a user, so that a user may personalize their own device and prevent others from using the device. This may be helpful in situations where monitoring of a vaporizer device is not always available and thus prevents another unauthorized user, such as child, from using the device.
The housing 109 is sized and configured to substantially house, or enclose, the components of the vaporizer device 100, to provide an external appearance to the device, and is shaped to fit ergonomically in the hand of a user. According to the embodiment shown in
The housing 109 may be made from any suitable material such as wood, metal, fiberglass, plastic, etc. In the embodiment shown in
According to the present disclosure, a wick element is configured to heat substances that are adjacent or in contact with the material of the wick element. Therefore, a vaporizable substance may be heated based on induction heating of the wick element by the induction heating element. According to embodiments, the wick element may also be configured to transfer a vaporizable substance from the reservoir based on a capillary action of the wick element. In embodiments where the vaporizable substance is a liquid or viscous substance, as the liquid is vaporized, more liquid moves up the wick element.
The configuration of the wick element may be a stranded wire, a stranded rope of material, a mesh, a mesh tube, several concentric mesh tubes, a cloth, sheets of material, or a foam (or other porous solid) with sufficient porosity, a roll of fine metal mesh or some other arrangement of metal foil, fibers or mesh, or any other geometry that is appropriately sized and configured to carry out the wicking action as described herein. The wick element may further comprises fins, protrusions, or other details that are configured to hold a solid or semi sold material in contact with the wick element.
The wick element may also be constructed of a combination of materials to achieve an appropriate effect. In one embodiment, the wick element is an interwoven cloth, or otherwise intimately mixed combination, of fine induction heating wires, strands, or threads with wicking wires, strands, or threads. In addition to a cloth or mesh configuration, the materials of the wick element may be combined in the form of a rope or foam, or suitably deployed thin sheets of material. In one embodiment, the wick element comprises rolled up alternating foils of material. The wick element is partially or completely surrounded by the induction coil that is not necessarily in contact with the mesh. As the wick element may be formed from a mesh, the mesh wick may be made of a material that is efficiently heated by induction such as a FeCrAl alloy. In one embodiment, the mesh wick may be formed using a Kanthal mesh. Additionally, the wick element may be removable from a cartridge so that the wick element is able to be cleaned and reused or replaced separate from the cartridge.
The materials used in the wick element may comprise a magnetic material or a metallic conductor. Further, the wick element may comprise materials that produce heat eddy currents or magnetic hysteresis when the wick element is exposed to an electromagnetic field. For example, magnetic or metallic conductor materials that have considerable hysteresis in the range of electromagnetic fields may be employed with the vaporizer device. In one embodiment, the wick element is comprised of a material such that heating is carried out both by eddy currents and also by movement of the magnetic domain walls. In one embodiment, the wick element material is iron. In another embodiment, the wick element comprises ceramic magnets, such as ferrite. In still another embodiment, the wick element comprises metallic conductors that heat by eddy currents. In yet another embodiment, the wick element comprises a semiconductor.
If the user wishes to directly vaporize extracts from plant material, then the same principle of induction heating can be used by replacing a liquid soaked wick element with a metal container. In embodiments, a metal container may be configured to heated by induction but may also allow airflow through the plant material. The metal container may be a sheet of mesh with the plant material rolled up in the sheet or it may be a solid or mesh cylinder with or without fins projecting into the volume of the cylinder. The spiral of foil or mesh and/or fins, allows the wick element to have little or no volume of plant material that is too far from a heated surface.
The tube 115 is sized and configured to be placed over an end 133 of the valve 113 that is distal from the cartridge and directs the vapor or aerosol from the vaporizable substance out of the mouthpiece component 117. In one embodiment, the tube 115 is a cylinder. The tube 115 may be formed any material that is appropriate, including, for example, glass. The tube 115 is configured to work with the valve to adjust airflow into and/or out of the vaporizer device 100 and, when closed, prevents leakage of the vaporizable substance.
Power is provided to the induction coil 121 from the power source 111. According to embodiments, the power source 111 may be any form of a device that consists of one or more electrochemical cells that convert stored chemical energy into electrical energy that is sized appropriately for the application. Accordingly, the power source 111 may be a battery, for example, which may be a primary battery or a secondary, or a rechargeable, battery. Further, the battery may be an alkaline battery, a watch battery, or Lithium Ion battery.
According to at least one embodiment, the electronic components of the vaporizer device 100 comprise a circuit that includes a current generating device, a processor, and at least one sensor. The power supplied to the induction coil can be controlled by the processor, which provides precise monitoring and control of the power supplied to the induction coil on a time scale that may be as low as a few milliseconds. According to embodiments, the processor is configured to receive information from the sensor and is able to adjust a heating profile applied to the wick element by the induction coil. The sensor may be able to detect or calculate such information as airflow from or into the vaporizer device, pressure at locations within the vaporizer device or of the vapor exiting device, and/or temperature of the components or locations near the components of the vaporizer device 100, such as the temperature of the induction coil. This would, for example, allow the circuit to sense that the user of the vaporizer device 100 is beginning to inhale and that a power level needs to increase to compensate for a tendency of the incoming air to cool the wick element below its ideal temperature. When an active inhalation is not in progress, the circuit may be able to then reduce the power to improve the life of the power source.
The processor may also be able to use this information to calculate and implement an optimal temperature profile. Furthermore, the processor may be configured to adjust a heating profile applied to the wick element by the induction coil based on the vaporizable substance. Therefore, the processor may be able to implement a predetermined heating profile according to the vaporizable substance. The processor may also allow the user to modify the settings or even the entire algorithm for providing the heat in order to obtain a best experience. The design and configuration of all of the electronic components can be sufficiently energy efficient to allow the vaporizer device to be hand held and battery operated. Additionally, the electronic components may comprise a printed circuit board and, according to embodiments, the processor may be a microprocessor or a microcontroller.
In another embodiment, the cartridge may comprise an identifier that comprises content information regarding the contents of the cartridge and the identifier may be incorporated into the cartridge such as with a barcode or other mechanism that provides a signal regarding a vaporizable substance and/or wick element within the cartridge. The processor may be coupled to the induction heating element and programmed to read the content information of the cartridge so that it is used to set parameters and cause the induction heating element to apply a heating profile to the vaporizable substance according to content information of the cartridge.
As shown in
As the cartridges allow for refilling and/or replacement, along with a variety of substances, a vaporizer device as described herein may be used as a general drug delivery system that could deliver drugs including medical marijuana and medicines that are vaporizable other than medical marijuana.
Referring back to
The USB port or other computer connection may facilitate communication with the microprocessor/microcontroller to enable changes and to verify the compatibility of hardware with software. By allowing hardware and software changes to the vaporizer device, few components may be swapped or even just the microprocessor/microcontroller code changed to enable different materials to be used or to allow different inhalation experiences by the user. Software, written to analyze and communicate with the device, will allow for greater control and variability of the induction heating element. Changes made in software will adjust the electronic control components onboard, such as a processor, as well. Users may be able to vary how hot a wick element gets as well as change the wick element itself. The USB port or other computer connection may also allow remote monitoring of the status of a vaporizer device by a manufacturer or retailer to improve product reliability but also to protect intellectual property by ensuring that only original manufactured components are used in the vaporizer devices. Also, in embodiments that include a rechargeable battery as the power source, the connection, such as the USB port, may also serve as the charger connector.
According to embodiments, the power source may comprise of a current generating device which may include an oscillating circuit. The oscillating circuit is configured to excite the required electro-magnetic field in the induction coil. The oscillating current may be of an energy efficient design and would operate at a frequency between a few tens of Hz to many megahertz. In embodiments, an AC current frequency is likely to be most effective in the hundreds of kHz range but may be suitable up to frequencies of many MHz. A suitable frequency that matches the skin depth of the electromagnetic penetration with the wire thickness of the wick element will results in optimal conditions. Other materials and arrangements of the wick element may provide different optimal frequencies.
Additionally, the airflow to be inhaled exits through a top 911 of the cartridge 901 and subsequently the mouthpiece component 117 of the vaporizer device 100. Incoming air, which mixes with the vapor or aerosol of the vaporizable substance, are also shown in
The wick element 907 shown in
Preheating the wick element may provide a more responsive vaporizer device 100. Employing the preheating element 1111 narrows the temperature range that the vaporizable substance or material is exposed to. When there is a strong airflow that is not preheated, it cools the wick down. In such a situation, power to the wick element may need to be higher than is optimal to pre-compensate for the cooling effect. With a preheater, the air is heated before it gets to the wick element and so the wick can be at a lower temp and still make a good aerosol.
Additionally, the airflow to be inhaled and the incoming airflow into the cartridge 1101 are shown. The insulating member 1109 provides a path for the airflow to be inhaled and is configured to allow incoming air to pass between the insulating member 1109 and the neck 1105 of the cartridge 1101. The preheating element 1111 may act as an upstream heating element, for example. Accordingly, if the airflow is arranged so that there are two concentric tubes with the incoming air flowing down, the single induction coil 1103 surrounds both the preheating element 1111 and the wick element 1107 heating them with the same oscillating electro-magnetic field. The relative temperatures and heating effectiveness of the two passive heating elements, the preheating element 1111 and the wick element 1107, may then be adjusted by their relative size and material properties to give the best experience to the user. In one embodiment, the induction coil 1107 may generate a current in the preheating element 1111 prior to creating a current in the wick element 1107. In addition, current may be generated in the preheating element 1111 and the wick element 1107 contemporaneously.
The induction coils may be excited in versatile ways to achieve different effects. The induction coils can be excited to produce a constant heat gradient profile or to move a hot zone along the length of the wick element in time or to provide a time dependent heat profile. The coils may also be excited at different frequencies to more effectively heat different components in the wick element. In one embodiment, the induction coils are activated according to a predetermined order. The order may be defined according to the most effective way to heat the wick element or the order may be defined according to the vaporizable substance associated with the wick element. In one embodiment, the wick element may be impregnated with different vaporizable substances along the length of the wick. Accordingly, the induction coils can be activated to produce a mixture of the vapors or aerosols produced by the different substances in flavors that are pleasing to a user. In one embodiment, the different vaporizable substances may be different flavors designed to mimic fruits or flavors of ice cream. A mixture of such flavors may enhance the user experience with the vaporizer device. Additionally, in embodiments, the induction coils may be formed as part of a replaceable cartridge such that the cartridge structure (the cartridge body, the wick element, and the induction coils) is designed to be replaced. Such a cartridge comprises electrical connections for the induction coils to connect with the electronic control components of the vaporizable device.
A further improvement on the vaporization of extracts directly from plant material that more closely reproduces the smoking of a cigarette is to heat only a fraction of a volume at a time starting at the bottom of the charge of plant material and progressively moving the heated disk of material along the charge until all of the desired extracts have been vaporized from the plant material. This may be achieved by having, in effect, multiple induction coils along the length of the cartridge so that the induction coils can be energized in turn thus moving the hot zone along the cartridge, similar to that shown in
The maximum power is consumed in circuit 1500 is by a voltage oscillator for the induction coil which is part of the induction heater drivers circuit 1517 which is fed by the induction heater power supply 1515. The induction heater drivers circuit 1517 may use around 7.3V with a power consumption of around 15 W. In the embodiment of
The microcontroller 1507 comprises a plurality of General Purpose Input/Outputs (GPIO) that couple the microcontroller 1507 to the induction heater power supply 1515, the user interface LEDs 1511, and the user interface switches 1509. The microcontroller 1507 provides Pulse Width Modulation (PWM) control signals to the induction heater power supply 1515. The microcontroller 1507 also includes a Bluetooth component (BLE) that allows the microcontroller 1507 to communicate with other components as appropriate. The microcontroller shown in FIG. 15 is an ARM Cortex MO processor designed by ARM Holdings. According to embodiments, other processors, controllers, circuit components, etc. may be used as appropriate. In additional embodiments, the functions of the microcontroller/microprocessor of the vaporizer device may be implemented with analog circuitry as appropriate. The sensor conditioners 1521 sense the power parameters, battery voltage and temperature of the battery, provided by the battery 1501 and provide signals to components of circuit 1500 as appropriate. The sensor conditioners 1521 then provide a signal to the microcontroller 1507 which is input to an AC/DC (ADC) converter of the microcontroller 1507. The sensor conditioners 1521 also provide signals to the induction heater power supply 1515 and temperature sensor 1519.
Temperature sensor 1519 senses the temperature at or near the wick element that is heated by the magnetic field from the induction coil. Temperature sensor 1519 is able to verify that the induction coil is heating the wick element properly based on communication with the induction heater drivers 1517. The user interface switches 1509 and user interface LEDs 1511 (Red Green and Blue) allow a user to interact with a vaporizer device and to receive feedback from the device.
Embodiments of the microcontroller/microprocessor of the vaporizer device automatically run a piece of software called the firmware. This software responds to user inputs and controls the power to the induction heater oscillator, senses the temperature, voltage and current to the induction heater coil and state of the battery and communicates via Bluetooth to a host device. According to user inputs and data sensed, the firmware also turns the feedback LED's on with a specific color to indicate a desired property examples of which are the state of battery charge (green could be >50%, yellow 15%-49%, red <15% and flashing red <5%) or simply that the device is on, in pre-heat mode or draw cycle.
In a simple embodiment of the firmware/device combination, the device functions as follows in a typical user setting. Pressing the button cycles through the following sequence:
1—press/release to power the device on
1—press/release to put the device from Power On to Pre-Heat mode
1—press to put the device from Pre/Idle Heat to Draw Heat mode
1—release to put the device from Draw Heat into Idle Heat mode
3—quick press/releases from any mode to power the device off.
On startup, the firmware checks the status of the battery and all inputs and then waits for input from the user via the button. Once the button is depressed, the firmware performs the following functions depending on the current and previous state of the instrument: In initial power on mode, the device can be accessed using a smart phone or other suitable Bluetooth device, any settings can be interrogated as well as data like the number of puffs etc. can be downloaded.
One press from startup goes to pre-heat mode. In this mode, the device maintains the vaping material at a pre-determined temperature so that there is less delay when the device is changed to the next setting. A second press initiates the draw cycle. The firmware increases the power to the coil to a predetermined level that gives a desirable and safe vapor for all the time the button is depressed. On button release, the device returns to pre-heat mode. This is repeated for the duration that the user wishes to use the device. A sequence of 3 button presses may be used to turn the device off.

Furthermore, the computing devices 4400 may be an iPhone™, an iPod™, an iPad™, a device operating the Android operating system (“OS”) from Google Inc., a device running the Microsoft Windows® Mobile OS, a device running the Microsoft Windows® Phone OS, a device running the Symbian OS, a device running the webOS from Hewlett Packard, Inc., a mobile phone, a BlackBerry® device, a smartphone, a hand held computer, a netbook computer, a palmtop computer, a laptop computer, an ultra-mobile PC, a portable gaming system, or another similar type of mobile computing device having a capability to communicate with clients 1601, 1602 and the host system 1604 via the communications networks 2800, 3800, 4600. The computing devices 4400 may include a suitable browser software application (e.g., Internet Explorer, Internet Explorer Mobile, Chrome, Safari, Firefox, Blazer, etc.) for enabling the user to display and interact with information exchanged via the communication networks 2800, 3800, 4600.
According to embodiments, an input device of the computing device 4400 may be one or more of a touch-sensitive display such as a touch screen interface, a keyboard, a microphone, or a pointing device such as a mouse or stylus. The computing device 4400 also include a display device capable of rendering an interactive Graphical User Interface (“GUI”) for providing commands to the clients 1601, 1602. The input device allows a user to interact with the GUI to instruct the clients 1601, 1602 and to display and edit information, which is rendered in the display device. The computing devices 4400 may thus access and navigate static and/or dynamic HTML, documents of the GUI. Alternatively, the GUI can be rendered on a display device of one or more servers, such as a web server 1800, application server 2000, and database server 2200 shown in
A display device of the computing device 4400 can differ depending on the application of the vaporizer device. For example, a display device of a tablet device, netbook, or laptop is typically an integrated LCD screen, which is often smaller than a monitor or console such as the display device for a workstation or desktop PC. Similarly, the display device of a mobile computing device may be a relatively small display such as mobile phone display.
The input devices can also vary depending on the characteristics of a particular computing device 4400 and its display device. For example, the input device of a tablet, netbook, or laptop may include a relatively small physical or touchscreen keyboard, an integrated camera, track pad, and/or microphone, while the input device of a desktop PC or workstation client will typically include a physical QWERTY or Dvorak keyboard and a mouse. Also, for example, an input device of a mobile device will typically lack a full physical keyboard and may instead comprise one or more of a touch-screen keyboard, a microphone, an integrated camera, a track pad, a scroll wheel, a track ball, a T9 keyboard, a button, and a touch screen display device. In embodiments, a display device can be a touch screen display. It is to be understood that in the case of a touch screen interface, the input device can be anything capable of interacting with the touch screen, including a user's fingers, which can be used to select, slide, drag, and resize (i.e., expand, maximize, shrink, and/or minimize) interactive user interface (“UI”) elements through pointing, pinching, and scrolling gestures.
According to embodiments, UIs for mobile computing devices may be rendered as streamlined ‘mobile friendly’ versions of the ‘full’ UI for ease of use on relatively small display devices. In embodiments, mobile friendly UIs may have reduced capabilities and/or display a lesser level of detail as compared to full UI. A mobile friendly UI can also be tailored to accept input from input devices for a specific platform of a mobile computing device. Mobile friendly UIs can be automatically selected by the system 1600 in response to detecting one or more platform characteristics of a particular mobile computing device. Alternatively, a user of a mobile computing device can be prompted within the full UI to opt-in to using the mobile friendly UIs in response to detecting that the computing device is accessing the host system 1604 via a mobile computing device. In cases where a user's mobile computing device has display devices and input devices capable of using the full UI, the user may not wish to use the mobile friendly UI.
In accordance with embodiments, the UI can be tailored to or customized for a particular computing device 4400 based on the capabilities of the platform used by that computing device. The platform comprises physical capabilities of the computing device such as, memory capacity in terms of random access memory (RAM) and read only memory (ROM), central processing unit (CPU) capabilities in terms of clock speed and available processing capacity, available storage in terms of disk space or flash memory, communications capabilities in terms of current wired and/or wireless network connectivity and a communications interface such as a network interface card (“NIC”) of the computing device, capabilities of the display device, and capabilities of the input device. These physical capabilities and others can be determined based on a manufacturer, model number, serial number, a Media Access Control address (“MAC address”) and/or another unique identifier of a computing device 4400.
The platform of a computing device 4400 also comprises software and firmware components, such as an operating system (“OS”) running on the computing device 4400, Internet browser(s), native software applications installed, and privileges/permissions associated with the computing device. The privileges/permissions may be controlled by the host system 1604 based on a user and/or an entity associated with the computing device and can include data access, communications, and application execution privileges.
