Patent Description:
An electronic smoking device, such as an electronic cigarette (or e-cigarette or eCig), typically has a housing accommodating an electric power source (e.g., a single use or rechargeable battery, electrical plug, or other power source), and an electrically operable atomizer. The atomizer vaporizes or atomizes liquid supplied from a reservoir and provides vaporized or atomized liquid as an aerosol. Control electronics control the activation of the atomizer. In some electronic cigarettes, an airflow sensor is provided within the electronic smoking device, which detects a user puffing on the device (e.g., by sensing an under-pressure or an airflow pattern through the device). The airflow sensor indicates or signals the puff to the control electronics to power up the device and generate vapor. In other e-cigarettes, a switch is used to power up the e-cigarette to generate a puff of vapor. <CIT> discloses vaporization devices and methods of operating them. Described therein are methods for controlling the power applied to a resistive heater of a vaporization device by measuring the resistance of the resistive heater at discrete intervals. Changes in the resistance during heating may be used to control the power applied to heat the resistive heater during operation. Also described therein are vaporization devices that are configured to measure the resistance of the resistive heater during heating and to control the application of power to the resistive heater based on the resistance values.

The characteristics, features and advantages of these embodiments and the manner in which they are obtained as described above, will become more apparent and be more clearly understood in connection with the following description of exemplary embodiments, which are explained with reference to the accompanying drawings.

In the drawings, the same element numbers indicate the same elements in each of the views:.

Throughout the following, an electronic smoking device will be exemplarily described with reference to an e-cigarette. As is shown in <FIG>, an e-cigarette <NUM> typically has a housing comprising a cylindrical hollow tube having an end cap <NUM>. The cylindrical hollow tube may be a single-piece or a multiple-piece tube. In <FIG>, the cylindrical hollow tube is shown as a two-piece structure having a power supply portion <NUM> and an atomizer/liquid reservoir portion <NUM>. Together the power supply portion <NUM> and the atomizer/liquid reservoir portion <NUM> form a cylindrical tube which can be approximately the same size and shape as a conventional cigarette, typically about <NUM> with a <NUM> diameter, although lengths may range from <NUM> to <NUM> or <NUM>, and diameters from <NUM> to <NUM>.

The power supply portion <NUM> and atomizer/liquid reservoir portion <NUM> are typically made of metal (e.g., steel or aluminum, or of hardwearing plastic) and act together with the end cap <NUM> to provide a housing to contain the components of the e-cigarette <NUM>. The power supply portion <NUM> and the atomizer/liquid reservoir portion <NUM> may be configured to fit together by, for example, a friction push fit, a snap fit, a bayonet attachment, a magnetic fit, or screw threads. The end cap <NUM> is provided at the front end of the power supply portion <NUM>. The end cap <NUM> may be made from translucent plastic or other translucent material to allow a lightemitting diode (LED) <NUM> positioned near the end cap to emit light through the end cap. Alternatively, the end cap may be made of metal or other materials that do not allow light to pass.

An air inlet may be provided in the end cap, at the edge of the inlet next to the cylindrical hollow tube, anywhere along the length of the cylindrical hollow tube, or at the connection of the power supply portion <NUM> and the atomizer/liquid reservoir portion <NUM>. <FIG> shows a pair of air inlets <NUM> provided at the intersection between the power supply portion <NUM> and the atomizer/liquid reservoir portion <NUM>.

A power supply, preferably a battery <NUM>, the LED <NUM>, control electronics <NUM> and, optionally, an airflow sensor <NUM> are provided within the cylindrical hollow tube power supply portion <NUM>. The battery <NUM> is electrically connected to the control electronics <NUM>, which are electrically connected to the LED <NUM> and the airflow sensor <NUM>. In this example, the LED <NUM> is at the front end of the power supply portion <NUM>, adjacent to the end cap <NUM>; and the control electronics <NUM> and airflow sensor <NUM> are provided in the central cavity at the other end of the battery <NUM> adjacent the atomizer/liquid reservoir portion <NUM>.

The airflow sensor <NUM> acts as a puff detector, detecting a user puffing or sucking on the atomizer/liquid reservoir portion <NUM> of the e-cigarette <NUM>. The airflow sensor <NUM> can be any suitable sensor for detecting changes in airflow or air pressure, such as a microphone switch including a deformable membrane which is caused to move by variations in air pressure. Alternatively, the sensor may be, for example, a Hall element or an electro-mechanical sensor.

The control electronics <NUM> are also connected to an atomizer <NUM>. In the example shown, the atomizer <NUM> includes a heating coil <NUM> which is wrapped around a wick <NUM> extending across a central passage <NUM> of the atomizer/liquid reservoir portion <NUM>. The central passage <NUM> may, for example, be defined by one or more walls of the liquid reservoir and/or one or more walls of the atomizer/liquid reservoir portion <NUM> of the e-cigarette <NUM>. The coil <NUM> may be positioned anywhere in the atomizer <NUM> and may be transverse or parallel to a longitudinal axis of a cylindrical liquid reservoir <NUM>. The wick <NUM> and heating coil <NUM> do not completely block the central passage <NUM>. Rather an air gap is provided on either side of the heating coil <NUM> enabling air to flow past the heating coil <NUM> and the wick <NUM>. The atomizer may alternatively use other forms of heating elements, such as ceramic heaters, or fiber or mesh material heaters. Nonresistance heating elements such as sonic, piezo, and jet spray may also be used in the atomizer in place of the heating coil.

The central passage <NUM> is surrounded by the cylindrical liquid reservoir <NUM> with the ends of the wick <NUM> abutting or extending into the liquid reservoir <NUM>. The wick <NUM> may be a porous material such as a bundle of fiberglass fibers or cotton or bamboo yarn, with liquid in the liquid reservoir <NUM> drawn by capillary action from the ends of the wick <NUM> towards the central portion of the wick <NUM> encircled by the heating coil <NUM>.

The liquid reservoir <NUM> may alternatively include wadding (not shown in <FIG>) soaked in liquid which encircles the central passage <NUM> with the ends of the wick <NUM> abutting the wadding. In other embodiments, the liquid reservoir may comprise a toroidal cavity arranged to be filled with liquid and with the ends of the wick <NUM> extending into the toroidal cavity.

An air inhalation port <NUM> is provided at the back end of the atomizer/liquid reservoir portion <NUM> remote from the end cap <NUM>. The inhalation port <NUM> may be formed from the cylindrical hollow tube atomizer/liquid reservoir portion <NUM> or may be formed in an end cap.

In use, a user sucks on the e-cigarette <NUM>. This causes air to be drawn into the e-cigarette <NUM> via one or more air inlets, such as air inlets <NUM>, and to be drawn through the central passage <NUM> towards the air inhalation port <NUM>. The change in air pressure which arises is detected by the airflow sensor <NUM>, which generates an electrical signal that is passed to the control electronics <NUM>. In response to the signal, the control electronics <NUM> activate the heating coil <NUM>, which causes liquid present in the wick <NUM> to be vaporized creating an aerosol (which may comprise gaseous and liquid components) within the central passage <NUM>. As the user continues to suck on the e-cigarette <NUM>, this aerosol is drawn through the central passage <NUM> and inhaled by the user. At the same time, the control electronics <NUM> also activate the LED <NUM> causing the LED <NUM> to light up, which is visible via the translucent end cap <NUM>. Activation of the LED may mimic the appearance of a glowing ember at the end of a conventional cigarette. As liquid present in the wick <NUM> is converted into an aerosol, more liquid is drawn into the wick <NUM> from the liquid reservoir <NUM> by capillary action and thus is available to be converted into an aerosol through subsequent activation of the heating coil <NUM>.

Some e-cigarette is intended to be disposable and the electric power in the battery <NUM> is intended to be sufficient to vaporize the liquid contained within the liquid reservoir <NUM>, after which the e-cigarette <NUM> is thrown away. In other embodiments, the battery <NUM> is rechargeable and the liquid reservoir <NUM> is refillable. In the cases where the liquid reservoir <NUM> is a toroidal cavity, this may be achieved by refilling the liquid reservoir <NUM> via a refill port (not shown in <FIG>). In other embodiments, the atomizer/liquid reservoir portion <NUM> of the e-cigarette <NUM> is detachable from the power supply portion <NUM> and a new atomizer/liquid reservoir portion <NUM> can be fitted with a new liquid reservoir <NUM> thereby replenishing the supply of liquid. In some cases, replacing the liquid reservoir <NUM> may involve replacement of the heating coil <NUM> and the wick <NUM> along with the replacement of the liquid reservoir <NUM>. A replaceable unit comprising the atomizer <NUM> and the liquid reservoir <NUM> may be referred to as a cartomizer.

The new liquid reservoir may be in the form of a cartridge (not shown in <FIG>) defining a passage (or multiple passages) through which a user inhales aerosol. In other embodiments, the aerosol may flow around the exterior of the cartridge to the air inhalation port <NUM>.

Of course, in addition to the above description of the structure and function of a typical e-cigarette <NUM>, variations also exist. For example, the LED <NUM> may be omitted. The airflow sensor <NUM> may be placed, for example, adjacent to the end cap <NUM> rather than in the middle of the e-cigarette. The airflow sensor <NUM> may be replaced by, or supplemented with, a switch which enables a user to activate the e-cigarette manually rather than in response to the detection of a change in airflow or air pressure.

Different types of atomizers may be used. Thus, for example, the atomizer may have a heating coil in a cavity in the interior of a porous body soaked in liquid. In this design, aerosol is generated by evaporating the liquid within the porous body either by activation of the coil heating the porous body or alternatively by the heated air passing over or through the porous body. Alternatively the atomizer may use a piezoelectric atomizer to create an aerosol either in combination or in the absence of a heater.

<FIG> is a cross-sectional side view of an e-cigarette. As shown in <FIG>, the e-cigarette <NUM> can include a battery <NUM> and a controller circuitry <NUM>. Electrical contact apertures <NUM>A-C can be located on the e-cigarette <NUM>. Electrical contacts or connectors <NUM>A-C can be electrically coupled with the controller circuitry <NUM>, and extend through at least a portion of the electrical contact apertures <NUM>A-C. As discussed in more detail below, the electrical connectors <NUM>A-C facilitate electrical communication between the controller circuitry <NUM> and external circuitry, as well as charging of the battery <NUM> by transmitting a current to the battery <NUM> from an external power source (e.g., external battery, charger, electronic device, among others).

The e-cigarette <NUM> can utilize software, hardware, firmware, and/or logic to perform a number of functions described herein. The e-cigarette <NUM> can include a combination of hardware and instructions to share information. The hardware, for example can include the controller circuitry <NUM> and/or a memory (not shown) (e.g., non-transitory computer-readable medium (CRM) database, etc.). The memory, as used herein, can include a number of processors capable of executing instructions stored by the memory resource. The memory can be integrated in a single device or distributed across multiple devices. The instructions (e.g., computer-readable instructions) can include instructions stored on the memory and executable by the memory for providing control over the e-cigarette <NUM> and/or performing various steps discussed in relation to <FIG>, in an example.

<FIG> are a drawings that shows an exemplary embodiment of the charger for charging a battery of the e-cigarette. <FIG> is an isometric side and top view of a charger for the e-cigarette shown in <FIG>, consistent with various aspects of the present disclosure. <FIG> is a top, cross-sectional view of the charger shown in <FIG>, taken along line B-B of <FIG>, consistent with various aspects of the present disclosure. <FIG> is a side, cross-sectional view of the charger shown in <FIG>, taken along line C-C of <FIG>, consistent with various aspects of the present disclosure.

A plurality of connecting pins <NUM>A-C can be configured to electrically connect to a plurality of connectors <NUM>A-C in the e-cigarette <NUM>. As shown in an exemplary embodiment in <FIG>, the charger <NUM> can have three connecting pins <NUM>A-C. The number of connectors <NUM>A-C/connecting pins <NUM>A-C can range from, for example, <NUM>-<NUM>. The connecting pins <NUM>A-C can have, for example a round cross-section and be cylindrically shaped. Other embodiments can use different sizes or shapes for the connecting pins (e.g., one round, one square, smaller or larger diameter and/or length, etc.) to aid with the desired configuration of the connection between the e-cigarette <NUM> and the charger <NUM>.

The three connecting pins <NUM>A-C can be used to connect with the corresponding connectors <NUM>A-C in the e-cigarette <NUM> for charging the battery <NUM> and to facilitate signals or messages between the e-cigarette <NUM> and the charger <NUM>. For example, a connecting pin <NUM>C can be connected to a ground and a connecting pin <NUM>B can be used for transmitting current from to a charging circuit, and a connecting pin <NUM>A can be used for sending a transmission of one or more signals or messages from the charger <NUM> to the e-cigarette <NUM> (e.g., sending a charge message, or a disconnect message, etc.). The connecting pin <NUM>B can, in some embodiments, be used to by the e-cigarette <NUM> to receive a signal or transmission from the charger <NUM> when the e-cigarette <NUM> is in the communication mode (and not in the charging mode). The signal going through the connector <NUM>B can be, for example, a high or a low signal. In some embodiments, the high and/or low signals can be used to trigger a switch between modes described in greater detail below.

In other embodiments, the arrangement/order of the connectors/connecting pins can be varied (e.g., connector/connecting pin <NUM>A/<NUM>A is ground, connector/connecting pin <NUM>B/<NUM>B is hot, connector/connecting pin <NUM>C/<NUM>C is sending/receiving, or connector <NUM>A/<NUM>A is hot, connector/connecting pin <NUM>B/<NUM>B is ground, and connector/connecting pin <NUM>C/<NUM>C is for sending/receiving, etc.). Additional connectors/connecting pins could be used (e.g., four connectors/connecting pins) to permit dedicated paths for sending and receiving signals. However, due to space constraints, a single connector that alternates between acting as the path that can send and receive signals can reduce the size of space needed in the e-cigarette <NUM> for the connectors.

The connectors/connecting pins can also be arranged in a configuration to prevent reversing a connection between the e-cigarette <NUM> and the charger <NUM>. For example, the spacing of the connectors/connecting pins can vary so that the charger <NUM> only connects to the e-cigarette <NUM> in one configuration. For example, a distance between connectors <NUM>A and <NUM>B can be different from the distance between connectors <NUM>B and <NUM>C. Other embodiments can use different sizes and/or different shapes for the connectors/connecting pins (e.g., one round, one square, etc.) to aid with the desired configuration of the connection between the e-cigarette <NUM> and the charger <NUM>.

The window <NUM> can facilitate viewing, by a user, a display or a light on the e-cigarette <NUM> that is located to correspond with the window <NUM> when the e-cigarette <NUM> is connected with the charger <NUM>. The window <NUM> can also be located to facilitate viewing a logo or other marking on the e-cigarette <NUM> when the e-cigarette <NUM> is connected with the charger <NUM>. One or more windows <NUM> can be included on the charger <NUM> and located at any suitable location. <FIG> shows an exemplary embodiment of the charger <NUM> with two windows <NUM>.

As shown in <FIG>, the charger <NUM> can be configured to electrically connect with the e-cigarette <NUM> to charge the battery <NUM> or to connect the e-cigarette <NUM> to, for example, a PC/computing device or some other processor using the charger <NUM> as a bridge. When acting as the bridge between the PC/mobile computing device and the e-cigarette <NUM>, the charger <NUM> can translate the information or data going between the PC/computing device and the e-cigarette <NUM> to facilitate the exchange. In the bridging scenario, the charger <NUM> does not edit or change the data. The PC/mobile computing device are exemplary embodiments of processors that can be connected to the charger <NUM>. Other embodiments can include, for example, a mobile phone (e.g., a "smart" phone), laptop or tablet computer or other similar device.

As shown in <FIG>, the charger <NUM> can include, for example, three connecting pins <NUM>A-C, a charger control electronics <NUM>, a charger memory <NUM>. A window <NUM> (not marked in <FIG>) is shown in <FIG>. The charger control electronics <NUM> can be electrically connected to a wire (not shown). The wire can also be connected to a connector (not shown). The connector can be any suitable connector including, for example, a universal serial bus (USB) connector.

The charger control electronics <NUM> can include a charger memory <NUM> and a charger processor (not shown). The charger <NUM> can be a synchronous state machine. The charger <NUM> can include one or more circuits in, for example, the charger control electronics <NUM>. The one or more circuits can be digital circuits that allow the charger processor of the charger <NUM> to be in various states or modes. The states or modes of the charger processor can include, for example, idle, communication, charging, disconnect, or other modes. Any of the states or modes can include one or more sub-modes. For example, the communication mode can include a diagnostic sub-mode and an update sub-mode. The charger modes are described in greater detail below.

The charger control electronics <NUM> can collect data from the e-cigarette <NUM> and the charger memory <NUM> can store the collected data. For example, the charger control electronics <NUM> can collect data about the last several batteries and/or atomizer/fluid reservoirs <NUM> that were connected to the charger <NUM> and the number of hours the e-cigarette <NUM> has been in use.

The charger <NUM> can utilize software, hardware, firmware, and/or logic to perform a number of functions described herein. The charger <NUM> can include a combination of hardware and instructions to share information. The hardware, for example can include the control electronics <NUM> and/or the charger memory <NUM> (e.g., non-transitory computer-readable medium (CRM) database, etc.). The charger memory <NUM>, as used herein, can include a number of processors capable of executing instructions stored by the memory resource. The charger memory <NUM> can be integrated in a single device or distributed across multiple devices. The instructions (e.g., computer-readable instructions) can include instructions stored on the charger memory <NUM> and executable by the charger processor and/or the charger memory <NUM> for providing control over the charger <NUM> and/or performing various steps discussed in relation to <FIG>, in an example.

In some embodiments, the charger <NUM> can include a wireless transmitter/receiver (not shown) to facilitate communication between the charger <NUM>/e-cigarette <NUM> and a PC/mobile computing device. This can include the use of Bluetooth technology or other wireless protocols.

The e-cigarette <NUM> can be a synchronous state machine. The e-cigarette <NUM> can include one or more circuits in, for example, the control electronics <NUM>. The one or more circuits can be digital circuits that allow the e-cigarette <NUM> to be in various states or modes. The states or modes of the e-cigarette <NUM> can include, for example, operation, charging, lower power sleep, light sleep, idle, disconnected, communication or other modes. Any of the states or modes can include one or more sub-modes. For example, the communication mode can include a diagnostic sub-mode and an update sub-mode.

An e-cigarette and a charger can be synchronous state machines. The e-cigarette and charger can each include one or more circuits. The one or more circuits can be digital circuits that allow the e-cigarette and the charger to be in various states or modes. The e-cigarette can synchronize with other devices (e.g., the charger, a case, etc.) and the charger can synchronize with other devices (e.g., the e-cigarette).

<FIG> is a state diagram that shows exemplary modes for an e-cigarette, consistent with various aspects of the present disclosure. The modes <NUM> of the e-cigarette <NUM> can include a low power sleep mode <NUM>, a communication mode <NUM>, a charge mode <NUM>, an operation mode <NUM>, and a light sleep mode <NUM>. In some embodiments, the low power sleep mode <NUM> can be the default mode for the e-cigarette <NUM> in order to maximize battery life.

The low power sleep mode <NUM> can maximize an operating time of the battery <NUM> in the e-cigarette <NUM> by, for example, limiting power used during various processes. For example, the airflow sensor <NUM> can be turned off to conserve power. While in the low power sleep mode <NUM>, the e-cigarette <NUM> cannot be used by a user (e.g., no puffs are possible). In some embodiments, the e-cigarette <NUM> can be in low power sleep mode <NUM> as a default mode and various actions and/or events can trigger a change in mode from the low power sleep mode <NUM> to a different mode.

For example, the low power sleep mode <NUM> can start when the atomizer/liquid reservoir <NUM> is disconnected from the e-cigarette <NUM> which is represented by connector link <NUM> in <FIG>. As shown in <FIG>, changes between some modes <NUM> (e.g., from the operation mode <NUM> to the communication mode <NUM>, or from the charge mode <NUM> the communication mode <NUM>, etc.) can require the e-cigarette <NUM> to transition through the low power sleep mode <NUM>. Other configurations are possible for the arrangement of modes <NUM> in the synchronous machine arrangement. For example, in other embodiments, the communication mode <NUM> can be the transitional mode (instead of the lower power sleep mode <NUM> shown as in <FIG>).

The e-cigarette <NUM> can be operated by a user in an operation mode <NUM>. The operation mode <NUM> can be activated when a user uses the e-cigarette <NUM> (e.g., sucks/puffs on the e-cigarette <NUM>). The operation mode <NUM> can also be trigged by, for example, connecting the atomizer/liquid reservoir <NUM> to the e-cigarette <NUM> (represented by connector link <NUM>) as a user may intend to use the e-cigarette <NUM> after the connection (e.g., puff right after inserting a cartridge or connecting the atomizer/liquid reservoir <NUM>).

The operation mode <NUM> can cause the e-cigarette <NUM> to, for example, activate the airflow sensor <NUM> during a puff causing the heating coil <NUM> to heat. In some embodiments, when the atomizer/liquid reservoir portion <NUM> is connected the e-cigarette <NUM> can switch from the low power sleep mode <NUM> to the operation mode <NUM>. In other embodiments, when the atomizer/liquid reservoir <NUM>, for example, is disconnected from the e-cigarette <NUM>, the e-cigarette <NUM> can switch into the low power sleep mode <NUM>.

During the operation mode <NUM>, the e-cigarette <NUM> can periodically check for use (e.g., detect puffs by a user). As the frequency of use decreases, the frequency of checks for use can also decrease. For example, while in the operation mode <NUM>, the e-cigarette <NUM> can check for use every <NUM>, and after <NUM> minutes of no use (e.g., no puffs by user) the e-cigarette <NUM> can increase the time between checks to four minutes.

The operation mode <NUM> can also have various sub-modes. For example, a stealth mode could vary one or more features of the e-cigarette <NUM> to minimize the visibility or other characteristic/feature of the e-cigarette <NUM>. For example, the stealth mode could reduce or disable light from an LED <NUM>, reduce power output so the heater coil <NUM> is a lower temperature which can cause the e-cigarette <NUM> to generate less vapour during use.

In some embodiments, the e-cigarette <NUM> can transition from the operation mode <NUM> to the light sleep mode <NUM> which can be represented by connector link <NUM> in <FIG>. Similar to the low power sleep mode <NUM>, the light sleep mode <NUM> can also reduce power usage of the e-cigarette to maximize battery life. In the light sleep mode <NUM> the airflow sensor <NUM> is still active but the e-cigarette <NUM> is in a reduced polling mode where the control electronics <NUM> check for usage less frequently compared to the operation mode <NUM>. This allows the e-cigarette <NUM> to transition from the light sleep mode <NUM> to the operation mode <NUM> (represented by a connector line <NUM>) in a shorter amount of time compared to transitioning from the low power sleep mode <NUM> to the operation mode <NUM>.

In some embodiments, the power usage of the e-cigarette <NUM> while in the light sleep mode <NUM> can be equal to the power consumption of the e-cigarette <NUM> while in the low power sleep mode <NUM>. In other embodiments, one of the modes could use less power (e.g., the low power sleep mode <NUM> could use less power than the light sleep mode <NUM> or the low power sleep mode <NUM> could use more power than the light sleep mode <NUM>).

The low power sleep mode <NUM> can have various different sub-modes. For example, the e-cigarette <NUM> can be in a full sleep mode, a travel sleep mode, or a deep sleep mode. The full sleep mode can occur when the e-cigarette <NUM> is, for example, connected to a charger that is connected to a power supply and the battery is fully charged. The travel sleep mode can be, for example, while the e-cigarette <NUM> is connected to a charger that is not connected to a power supply. The deep sleep mode can occur, for example, when the e-cigarette <NUM> does not have the atomizer/liquid reservoir <NUM> connected (e.g., no puffs are possible) and the e-cigarette <NUM> is not connected to a charger. All sleep modes effectively reduce the power consumption (e.g., to a lowest possible level).

In some embodiments, the e-cigarette <NUM> can include a communication mode <NUM> as seen in <FIG>. The communication mode <NUM> can be triggered by, for example, connecting the e-cigarette <NUM> to a charger <NUM> (represented by connector link <NUM>). While in the communication mode <NUM>, the e-cigarette <NUM> can detect the charger <NUM> and announce itself by sending a first signal or message to the charger <NUM> (e.g., passively or actively). In response, the charger <NUM> can send a second signal to the e-cigarette <NUM>, acknowledging the announcement. The second signal can trigger the start of the communication mode <NUM>. The communication mode <NUM> can end when the e-cigarette <NUM> receives, for example, a sleep message from the control electronics <NUM> or when the e-cigarette <NUM> switches to the charge mode <NUM>. The communication mode <NUM> can end and the e-cigarette <NUM> can transition to the low power sleep mode <NUM> (represented by connector link <NUM>) or the e-cigarette <NUM> can transition to the charge mode <NUM> (represented by connector link <NUM>).

The sleep message can be generated by, for example, disconnecting the e-cigarette <NUM> from the charger <NUM>. In another embodiment, if the e-cigarette <NUM> is connected to a charger <NUM> that is not connected to an external power source (e.g., external battery, charger, electronic device, connected to an AC outlet among others) the e-cigarette <NUM> can return and/or stay in the low power sleep mode <NUM> or the light sleep mode <NUM>. The sleep message can cause the e-cigarette <NUM> to change from the charger mode <NUM> to the low power sleep mode <NUM> after the battery <NUM> is at a maximum charge. If the e-cigarette <NUM> is in the communication mode <NUM> and connected to the charger <NUM>, the charger can also be in the communication mode <NUM>.

When the e-cigarette <NUM> is in the communication mode <NUM> and connected to the charger <NUM>, a charge message can cause the e-cigarette <NUM> switch from the communication mode <NUM> to the charge mode <NUM> and begin charging the battery <NUM>. The e-cigarette <NUM> can continue charging the battery <NUM> until, for example, the charger <NUM> is disconnected or the e-cigarette <NUM> attains a full charge on a battery <NUM>. If the charger <NUM> is disconnected from the e-cigarette <NUM> or the battery <NUM> has a full charge the e-cigarette <NUM> can switch from the charge mode <NUM> to the low power sleep mode <NUM>.

As discussed above, in some embodiments, the e-cigarette <NUM> can be disposable. For disposable e-cigarettes the battery may not be rechargeable. In some embodiments, the disposable e-cigarette may not have low power modes. In this embodiment, the low power sleep and light sleep modes may not exist but other modes discussed herein may still be used and other additional modes may be included.

In some embodiments, the e-cigarette <NUM> can periodically change from a low power mode (e.g., the low power sleep mode <NUM> or the light sleep mode <NUM>) to another mode. This periodic change can be thought of as "waking" from the low power mode to, for example, perform a task and/or monitor an operation, system or hardware. The periodic waking can control the various sleep modes (e.g., full sleep, travel sleep, and deep sleep) and can ensure the control electronics <NUM> is operating properly. For example, the e-cigarette <NUM> can wake to run a diagnostic operation in the diagnostic sub-mode of the communication mode <NUM>. The periodicity of the waking can be controlled by a timer or triggered by some other event (e.g., connecting the e-cigarette <NUM> to the charger <NUM>, the atomizer/liquid reservoir <NUM>, a carry case, etc.). Connecting or disconnecting the e-cigarette <NUM> from an accessory or other device (e.g., a PC/computing device, a mobile phone, or other processor) can change the periodicity of the waking.

The communication mode <NUM> can include various other sub-modes. For example, after the e-cigarette <NUM> is in the communication mode <NUM>, a diagnostic mode or an update mode can be started. The diagnostic mode can be used to diagnose various parts of the e-cigarette <NUM>. For example, one more tests can be run on the constituent systems of the e-cigarette <NUM> (e.g., the control electronics <NUM>, the battery <NUM>, the atomizer/liquid reservoir portion <NUM>, etc.). The diagnostic mode can also allow an e-cigarette memory to be collected (e.g., downloaded to a PC/mobile computing device, uploaded to a web site, etc.). Information stored in the e-cigarette memory can include, for example, the serial number of the e-cigarette <NUM>, the serial number of the atomizer/liquid reservoir portion <NUM>, or other information. The update mode can be used to, for example, provide firmware and/or software updates to the e-cigarette <NUM>.

If the e-cigarette <NUM> is in the communication mode <NUM>, the charger <NUM> can also synchronize to be in the communication mode <NUM> (shown in <FIG>). Similarly, if the e-cigarette <NUM> is in the charge mode <NUM>, the charger <NUM> can also synchronize to be a charge mode (discussed in more detail below). Other combinations of modes are possible when the e-cigarette <NUM> and the charger <NUM> synchronize (e.g., if the e-cigarette is in the lower power sleep mode <NUM>, and connected to the charger <NUM>, the charger <NUM> can be in an idle mode (discussed in more detail below)).

In some embodiments, the charger <NUM> can include the control electronics <NUM> that includes, for example, a memory <NUM>. The charger memory <NUM> can collect data from the e-cigarette <NUM>. For example, the charger memory <NUM> can collect data about the last several batteries that were connected to the charger <NUM> and the number of hours the e-cigarette <NUM> has been in use.

<FIG> is a state diagram that shows exemplary modes for the charger for the e-cigarette of <FIG>, consistent with various aspects of the present disclosure. The charger <NUM> can have various modes <NUM>, including an idle mode <NUM>, a communication mode <NUM>, a charge mode <NUM>, and a disconnect mode <NUM>. The communication mode <NUM> and the charge mode <NUM> are described herein. The idle mode <NUM> can reduce energy used by the battery <NUM> by, for example, turning down a processor clock in the control electronics <NUM> and turning off peripheral electronics (e.g., the LED <NUM>) and any other processes not necessary.

The charger <NUM> can be in an idle mode <NUM>. In some embodiments, the idle mode <NUM> can be the default mode for the charger <NUM>. If the charger <NUM> is not connected to the e-cigarette <NUM> or a PC/mobile computing device the charger <NUM> can be in the idle mode <NUM>. If the e-cigarette <NUM> is initially connected to the charger <NUM> and then disconnected from the charger <NUM>, the charger <NUM> can switch to the idle mode <NUM>.

Connecting the e-cigarette <NUM> to the charger <NUM> can cause the charger <NUM> to switch from the idle mode <NUM> to the communication mode <NUM> (represented by connector link <NUM> in <FIG>). Conversely, disconnecting the e-cigarette <NUM> from the charger <NUM> can cause the charger <NUM> to switch from the communication mode <NUM> to the idle mode <NUM> (represented by connector link <NUM> in <FIG>).

In some embodiments, the charger <NUM> can determine or negotiate a rate of charging of the battery <NUM> in the e-cigarette <NUM>. The negotiation can occur when the charger <NUM> and the e-cigarette <NUM> are connected and both in communication mode (e.g., the e-cigarette <NUM> in communication mode <NUM> and the charger <NUM> in communication mode <NUM>). The charge message can be sent by the charger <NUM> to the e-cigarette <NUM>. In response, the e-cigarette <NUM> can send a response signal back to the charger <NUM>. The charger <NUM> can then determine a rate of charging for the battery <NUM>.

The rate of charging can vary for a number of reasons. For example, connecting the e-cigarette <NUM> to a PC/mobile computing device via a USB connection (or other similar connection) may not allow the same charge rate compared to using a charger <NUM> with a charge block that accepts a charge block (e.g., as a USB plug) and also fits into electrical outlets (e.g., to metal prongs that fit into and electrical outlet ) or other adapter connected to a typical household AC circuit (e.g., <NUM> v/<NUM> or 220V/<NUM>) or other external power source (e.g., external battery, etc.). As an example, the charger <NUM> can be rated for <NUM>-<NUM> mA. In some embodiments, a higher charge rate can be negotiated (e.g., <NUM> mA) depending on the properties of the battery <NUM> and the type of connection supplying electricity to the charger <NUM>.

The charger <NUM> can switch from the communication mode <NUM> to the charge mode <NUM> (represented by connector link <NUM> in <FIG>) after the charge message/reply message are sent between the e-cigarette <NUM> and the charger <NUM> (e.g., the e-cigarette <NUM> is in control of a charge negotiation) and the charge negotiation is complete. In another embodiment, instead of the charge message being sent from the e-cigarette <NUM> to the charger <NUM>, the charger <NUM> can send a message to the e-cigarette <NUM> after the e-cigarette <NUM> is connected to the charger <NUM> (e.g., the charger <NUM> is in control of the charge negotiation).

When the e-cigarette <NUM> has a battery <NUM> that is fully charged the e-cigarette can switch to a low power mode (e.g., the low power sleep mode <NUM>, the light sleep mode <NUM>, etc.) and the charger <NUM> can switch from the charge mode <NUM> to the idle mode <NUM> (represented by connector link <NUM> in <FIG>). If the e-cigarette <NUM> in the charge mode <NUM> and is connected to the charger <NUM>, the charger <NUM> can also synchronize to be in the charge mode <NUM>.

The charger <NUM> can be placed in the disconnect mode <NUM> by, for example, disconnecting the charger <NUM> from the PC/computing device if the e-cigarette is already connected to the charger <NUM> (represented by connector link <NUM> in <FIG>). The disconnect mode <NUM> can be ended by connecting the charger <NUM> to the PC/computing device (represented by connector link <NUM> in <FIG>) if the charger is not connected to the PC/computing device.

<FIG> is a chart that shows exemplary times that the e-cigarette can be turned on and turned off while in the light sleep mode, consistent with various aspects of the present disclosure. The light sleep mode <NUM> can reduce energy used by the battery <NUM> by, for example, turning down a processor clock and turning off peripheral electronics and any other processes not necessary (e.g., the LED <NUM> etc.). In one example shown in <FIG>, the e-cigarette <NUM> can be turned on for <NUM> and then turned off for <NUM>. In another embodiment, the e-cigarette <NUM> can be turned on for <NUM> and then turned off for <NUM>. Longer periods with the e-cigarette <NUM> off can be used in the low power modes (e.g., low power sleep mode <NUM>, light sleep mode <NUM>, etc.). The length of time the e-cigarette <NUM> is turned off can vary. For example, "on" times can range between <NUM>-<NUM> and "off" times can range between <NUM>-<NUM> depending on the activity of the user with the e-cigarette <NUM>. In one example, immediately after the e-cigarette <NUM> is used (e.g., the user sucks/puffs on the e-cigarette <NUM>) a first off time can be <NUM>. After a first period of time the e-cigarette <NUM> can change to a second off time of <NUM>. After a second period of time the e-cigarette <NUM> can change to a third off time of <NUM>. The number of different off times can vary.

<FIG> is a block diagram illustrating data communication pathways between an exemplary e-cigarette and a processor, consistent with various aspects of the present disclosure. <FIG> shows exemplary connections between an e-cigarette <NUM> and a charger <NUM> and the charger <NUM> and a processor <NUM> (e.g., a PC/computing device, a mobile phone, a remote server, etc.). A first connection <NUM> between the e-cigarette <NUM> and the charger <NUM> can be, for example, a serial connection. The serial connection is previously described above in more detail. A second connection <NUM> can be between the charger <NUM> and a processor <NUM> (e.g., a personal computer, a tablet computer, a mobile "smart" phone, or other similar device). The second connection <NUM> can be any suitable electrical connection between the charger <NUM> and the processor <NUM>.

The e-cigarette <NUM> can connect to a charger <NUM> in order to charge the battery <NUM> (see <FIG>) of the e-cigarette <NUM>. In addition to this charging function, the charger <NUM> can exchange data with the e-cigarette <NUM>. The data exchange can occur, for example, through a dedicated data line or signals obtained from a power line connecting the charger <NUM> and the e-cigarette <NUM> during charging. When a data line is used to transfer data between the e-cigarette <NUM> and the charger <NUM>, the data line can be a physical wire connection or a wireless communication. In an embodiment, the data that can be transferred from the e-cigarette <NUM> to the charger <NUM> includes identifying data, such as a serial number, a calibration parameter, a batch code, a line number, or a barcode associated with the e-cigarette <NUM>. In another embodiment, the data that can be transferred from the e-cigarette <NUM> to the charger <NUM> includes usage data, such as a number of puffs taken, an average length of puffs taken, a smoke juice level, a smoke juice flavor, or a location of use.

The charger <NUM> can act as a bridge connection between the e-cigarette <NUM> and the processor <NUM> (e.g., a personal computer (PC). While acting as the bridge connection between the e-cigarette <NUM> and the processor <NUM> the charger <NUM> does not add to or change the content of the data or information transmitted between the e-cigarette <NUM> and the processor <NUM>. The processor <NUM> can be, for example, an external processor that is external to the e-cigarette <NUM> and to the charger <NUM>. The external processor can be configured to communicate with the control electronics <NUM> and the charger control electronics <NUM> when the e-cigarette <NUM> is electrically connected to the charger <NUM>.

The serial connection can be used to, for example, connect the e-cigarette <NUM> to the charger <NUM> to, for example, negotiate the charge rate of the e-cigarette <NUM> by the charger <NUM> or transmit signals or messages between the e-cigarette <NUM> and the charger <NUM> as described herein.

The second connection <NUM> can be used to, for example, update firmware on the e-cigarette <NUM> and/or the charger <NUM>. The firmware can be transmitted from the memory that is part of the processor <NUM> or from a remote server, passing through the charger <NUM>, to the e-cigarette <NUM>. In other embodiments, the second connection <NUM> can permit the exchange of data (e.g., diagnostic data) between the processor <NUM> and the e-cigarette <NUM>. In another embodiment, the second connection <NUM> can permit data stored on a memory device on the e-cigarette <NUM>.
