Abstract

A container is provided that is configured to store consumables for consumption with an electronic device. The container includes: at least one actuator configured to perform an action associated with the container; and a radio frequency energy harvesting RF-EH system comprising an energy storage device wherein the RF-EH system is configured to obtain energy from an ambient radio frequency signal to store the energy in the energy storage device and to power the at least one actuator.

Description

[0001] This disclosure relates to containers configured for storing consumables, devices, or accessories.

[0002] Consumables or consumable articles are non-durable articles that are intended for immediate consumption. These consumables may interact with or be used by electronic devices. They may be housed in containers, such as packaging or boxes, configured to store multiple consumables. An example of a consumable is a risk-reduced product (RRP). An electronic device may be an aerosol-generating device configured to interact with consumables that are aerosol-generating articles.

[0003] However, a problem with such containers used for storing consumables is that their functionality is limited. For example, conventional containers are limited to printed information on the outside of the container used to send messages to the user. However, these containers do not allow any kind of interaction with the user. Specifically, these containers do not allow the transmission or sending of signals to the user in response to user interaction.

[0004] Another drawback of having only printed information on the container is that, in certain situations, such as at night or in a dark room, the information may not be received by the user, excluding people such as the blind from receiving the information.

[0005] Another problem with conventional containers used to store consumables is that these containers can be copied by third parties other than the manufacturer. The appearance of the containers can be easily replicated, and counterfeit products can be sold in such containers without the user's knowledge. Manufacturers of containers containing consumables have no control over the counterfeiting of these consumables and do not know how these consumables are produced or what the counterfeit consumables are made of. Therefore, manufacturers cannot guarantee that these counterfeit consumables in containers with copied appearances will not pose a danger to users.

[0006] Typically, manufacturers limit themselves to a printed outer layer of the container, which may be made of cardboard or paper, to differentiate their products. This printed outer layer can be easily replicated. Manufacturers can use other materials for the container to distinguish it from other products. However, these other materials often increase production costs or have a greater environmental impact. Furthermore, conventional containers may not be perceived as sustainable by users because their sole purpose is to store consumables, and once the last consumable item in the container is used, the container no longer serves a purpose and can be discarded.

[0007] Therefore, there is a need to provide an improved container for storing consumables and providing enhanced functionality without ignoring the environmental impact.

[0008] According to one aspect of the invention, a container configured to store consumables consumed using an electronic device is provided. The container includes at least one actuator and a radio frequency energy harvesting (RF-EH) system, the at least one actuator being configured to perform actions associated with the container, the RF-EH system including an energy storage device. The RF-EH system is configured to obtain energy from an ambient radio frequency signal. The RF-EH system is configured to store the obtained energy in the energy storage device and to power the at least one actuator. The at least one actuator can be powered by feeding the energy stored in the energy storage device to the at least one actuator or a subset of the at least one actuator.

[0009] By providing a container with an RF-EH system for powering the actuator, the container's functionality can be increased without neglecting its environmental impact. Actuators embedded in or included within the container allow users to quickly identify the container and differentiate it from similar products from other manufacturers.

[0010] According to various aspects, the energy storage device is configured to feed energy stored in the energy storage device to at least one actuator in response to at least one of the following: (i) one or more actions applied to the container, (ii) a specified time, (iii) a specific amount of energy stored in the energy storage device, and (iv) a random time after the last energy feed to at least one actuator.

[0011] According to one aspect, the container includes a sensor configured to detect a signal, wherein, in response to the detected signal, energy stored in an energy storage device is fed to at least one actuator. The energy storage device may include a capacitor configured to control a transistor.

[0012] The actuator can be activated by feeding energy into it. Activating the actuator in response to sensor signals or actions applied to the container provides an improved container with enhanced user interaction.

[0013] According to one aspect, the transistor can be configured to become conductive when the energy stored in the capacitor equals or reaches a gate-source threshold, causing the capacitor to discharge to at least one actuator. Alternatively, the energy storage device may include a primary capacitor and a secondary capacitor. The secondary capacitor can be configured to control the transistor. Since the secondary capacitor is charged through a resistor, the primary capacitor can be charged faster than the secondary capacitor. The transistor can be configured to become conductive when the energy stored in the secondary capacitor equals or reaches a gate-source threshold, causing the primary capacitor to discharge to at least one actuator.

[0014] Depending on various aspects, the container includes a switch. An energy storage device can be configured to feed energy stored in the energy storage device to at least one actuator in response to the switch being closed. The switch can be embedded in the container and configured to transition from an open state to a closed state when the container is opened. The container may include a lid configured to be opened by a rotational movement. The switch may include at least one leg configured to contact the conductive layer only when the lid is opened to close the switch. The at least one actuator may be an LED.

[0015] Depending on the aspect, the energy storage device includes a variable capacitor having at least one flexible electrode. The variable capacitor may be connected to the gate of a transistor. When the distance between the two electrodes of the variable capacitor decreases, the transistor may become a conductor to feed energy to at least one actuator. The variable capacitor may be arranged within a container such that the distance between the two electrodes of the variable capacitor decreases when a user presses at least one side of the container.

[0016] Depending on the aspects, the RF-EH system is a foldable RF-EH system integrated into paper or cardboard. At least one actuator may include at least one of an LED, an LED array, a speaker, a vibration device, and an array of vibration devices. At least one actuator may include a low-power light system actuator. The low-power light system actuator may be configured to provide light toward the interior of the container to illuminate the contents of the container.

[0017] Depending on the circumstances, the energy storage device is configured to feed energy to at least one actuator in response to a user of the container applying force to at least one of the container and the energy storage device.

[0107] This encompasses various aspects of packaging for RRP (Risk-Reduced Product), consumables, and devices. In particular, RRP packaging for stick-shaped consumables can resemble conventional product packaging, except for its size. The appearance and shape of such packaging or containers allow consumers to identify heat-not-burn consumables. However, it may be desirable to make the packaging more strongly convey the difference between RRP and conventional products.

[0108] The goal is to produce efficient and environmentally friendly containers with added functionality for signaling to or assisting users.

[0109] The following text will primarily describe containers used for consumables. However, depending on the circumstances, containers can be used for packaging or storing electronic heating devices, or for packaging any kind of product.

[0110] The aspects will be described with respect to an aerosol generation (or delivery) system using an electronic device (“RRP device”) and a consumable disposed in a container (such as a package or box). The container may include an e-liquid bottle having a cylindrical shape and a cellulose-based parallelepiped package. The RRP system may include a heat-not-burn (“HnB”) system, which may be based on a resistance or induction heating system for external or internal heating of the consumable (such as a cylindrical consumable).

[0111] Depending on various aspects, the container may include packaging. The container may be configured to store one or more risk-reduced products, consumables, devices, or accessories. The container includes a radio frequency energy harvesting (“RF-EH”) system. The RF-EH system may be embedded in the container or packaging. Additionally, the container may include at least one actuator. The at least one actuator may be embedded inside or outside the container or packaging and may be connected to the RF-EH system. The at least one actuator may be an LED, a vibration device, etc. The RF-EH system may be configured to store electrical energy. The electrical energy may be stored in an energy storage device included in the RF-EH system. The stored energy may be fed to one or more actuators of the container based on at least one of the following: actions applied to the container or packaging, the amount of stored or harvested energy, and signals obtained by sensors of the container.

[0112] The RF-EH system can be configured to supply power to at least one actuator. The RF-EH system can be configured to activate at least one actuator, which can be embedded within the container. The at least one actuator can be configured to provide at least one signal perceptible to a user. The user can be a consumer of the container or someone passing by it. The signal can generate an attention-attracting effect. An advantage of the RF-EH system is that at least one actuator can be powered inside the container without the need for a battery. This can save on manufacturing costs and is environmentally friendly compared to containers with batteries.

[0113] According to various aspects, the container may include sensors connected to the RF-EH system. The sensors may be configured to capture or detect signals. At least one actuator may be configured to perform an action in response to the captured signal. The captured signal may trigger the actuator. According to one aspect, the container may include electronic circuitry, such as actuation circuitry, which may be more complex than a simple actuator and may be connected to the RF-EH system for using the RF-EH system as a power provider. The electronic circuitry may include oscillator circuitry, amplifier circuitry, and at least one of various actuators.

[0114] Figure 1 An exemplary circuit 100, which can be embedded in a container, is shown, including an RF-EH system 110 and an actuator 120. This circuit can be used to trigger the actuator 120 based on the amount of energy stored in the energy storage device of the RF-EH system 110. This circuit can also be used to randomly (determined by how much energy is harvested by the RF-EH circuitry) trigger the actuator from time to time to provide a signal to the user that generates “attention” or provides an unexpected event.

[0115] The RF-EH system 110 may include an energy storage device. For example, the energy storage device may include a capacitor 140. The capacitor 140 may be configured to control the gate of a transistor 130. The transistor 130 may be a normally off MOSFET transistor, a negative threshold MOSFET, or a depletion-type pMOSFET. When the energy stored in the capacitor 140 causes the voltage of the capacitor 140 to fall below the gate-source threshold voltage of the transistor 130, the transistor 130 becomes a conductor, and the capacitor 140 may discharge to the actuator 120.

[0116] The figure shows only the main components of the corresponding circuit. The circuit may include additional components. For example, circuit 100 may include a resistor (not shown) to slow down the discharge of a capacitor.

[0117] Figure 2An exemplary circuit 200 is shown, including an RF-EH system 110, an actuator 120, and a transistor 130. Additionally, circuit 200 includes a first capacitor 140 and a second capacitor 242. The first and second capacitors can form an energy storage device for the RF-EH system. The first capacitor 242 can be a dedicated capacitor connected to the gate of a transistor, such as a normally-off MOSFET, a negative threshold MOSFET, or a depletion-type pMOSFET. When the RF-EH system 110 receives an ambient RF signal, the first capacitor 242 (which can be a secondary capacitor) can be charged by the RF-EH system 110. Similarly, when the RF-EH system 110 receives an ambient RF signal, the second capacitor 140 (which can be a primary capacitor) can also be charged by the RF-EH system 110. Due to the resistance of resistor 250, the first capacitor 242 can be charged more slowly than the second capacitor 140. When the first capacitor 242 reaches a voltage sufficient to allow the transistor 130 to leave its cutoff region, the transistor 130 becomes a conductor, and the second capacitor 140 can discharge the actuator 120.

[0118] The corresponding values ​​of the capacitor and resistor can be determined such that when the second capacitor can provide sufficient energy to the actuator, the first capacitor is configured to reach a value at which the transistor 130 (e.g., a MOSFET transistor) becomes a conductor. The transistor becoming a conductor means that the transistor becomes conductive between its drain and source when one or more capacitors configured to control the gate of the transistor have stored sufficient energy to reach a voltage sufficient to move the transistor out of its cutoff region. Figure 1 and Figure 2 In the diagram, transistor 130, such as a depletion-type pMOSFET, is shown having its gate “G” and its source “S”.

[0119] Depending on various factors, a container can be configured to activate an actuator in response to the container being opened or opened. When a user opens the container, the actuator can be triggered. Figure 3 An exemplary circuit for triggering an actuator included in a container is shown in the figure.

[0120] Figure 3 An exemplary circuit 300 for a container is shown. Circuit 300 includes an RF-EH system 110, an actuator 120, a capacitor 140, and a switch 360. The purpose of this circuit is to trigger the actuator when a user opens the lid of the packaging or container. The container may have a hinged lid. The actuator may be an LED pointing towards the interior area of ​​the packaging when the lid is opened.

[0121] exist Figure 3In this configuration, switch 360 is configured to prevent storage capacitor 140 from discharging to actuator 120 in the "open" state. The switch can be configured to transition from the "open" state to the "closed" state when the container is opened. For example, the switch can close when the container lid is opened or is opened. When the switch is closed, storage capacitor 140 is configured to feed actuator 120. Actuator 120 can be activated when capacitor 140 has been fully charged by the RF-EH system.

[0122] Figure 4A A side sectional view of a container 401 (e.g., a consumable package) is shown, which has a cardboard outer frame 402, a hinged lid 403, an inner liner 404, and consumables 405. Figure 3 The circuit 300 may be included in the container 401. For example, the actuator 411 may correspond to... Figure 3 Actuator 120. Actuator 411 can be embedded in the container. Figure 3 Circuit 300 can correspond to the absence of actuator 120 and half of switch 360. Figure 4A 410 in. Figure 4A In this context, the actuator 411 may be an LED configured to illuminate the interior of the container 410.

[0123] Figure 4B It shows Figure 4A Details of the opening of the 403 cover. Figure 4A On the right side, the lid is closed. Figure 4B In the middle, cover 403 is opened. By opening cover 403, the switch can be closed. For example, the two open legs of the switch in circuit 410 can be configured to contact conductive layer 412 due to rotation of cover 403, which closes the switch. In response to the switch closing, actuator 411 can be activated. Actuator 411, in the form of an LED, can be configured to illuminate the interior of the container with light 413.

[0124] Figure 5A An exemplary circuit 500 for a container is shown according to one aspect. The circuit includes an RF-EH system 110, an actuator 120, a capacitor 140, a variable capacitor 546, and a transistor 130. According to one aspect, the circuit 500 can be embedded in the container such that a user's action, such as a touch or press by the user on the container or its surface, triggers the actuator 120. The variable capacitor 546 can be configured to act as a sensor for detecting the user's action. The variable capacitor 546 may include at least one flexible electrode. The variable capacitor 546 can be charged. For example, one electrode of the variable capacitor 546 may be a charged flexible film, such as a charged electret film coated with metal, wherein the metallized coating is grounded, and a second electrode may be a post-metallized plate.

[0125] A variable capacitor 546 is connected to the gate of transistor 130, whose source is grounded, such that the transistor's voltage threshold (which may be negative) is larger than, i.e., smaller negative, than the negative gate-source voltage associated with the variable capacitor 546 in the unpressed state. Therefore, the transistor is non-conductive and prevents capacitor 140 from discharging to actuator 120. Transistor 130 may be a MOSFET or a depletion-type nMOSFET. The unpressed state can be a state where no force is applied to the variable capacitor 546. When force is applied to the variable capacitor 546, it can be in a pressed state. A user can apply force to the container or the variable capacitor 546, for example, by touching or pressing the container, reducing the distance between the two electrodes of the variable capacitor 546. For example, when the packaging is pressed, the distance between the charged flexible film and the backing plate decreases. The electrodes of the variable capacitor 546 may be separated by foam between the outer frame of the carton and the inner liner.

[0126] Figure 5B A schematic diagram shows the container being pressed by user 520. (As shown) Figure 5B As can be seen on the right, when the packaging is pressed, the thickness between the outer frame of the container's cardboard box and the inner liner 504 decreases. As this distance decreases, the capacitance C of the variable capacitor 546 increases. The capacitance of a capacitor is inversely proportional to the distance between its electrodes. Because the charge is constant, and due to the capacitance equation... The absolute value of the voltage across the variable capacitor 546 decreases and can pass through the voltage threshold of the transistor 130, thus making the transistor 130 conductive. For example, the negative gate-source voltage associated with the variable capacitor 546 in the pressed state becomes smaller and can be higher than or reach the voltage threshold of the transistor, making the transistor act as a conductor. The variable capacitor 546 is configured such that when it comes into contact with a container or package, the voltage decrease is sufficient to move the transistor out of its cutoff region. The voltage associated with the variable capacitor 546 in the pressed state can be higher than the gate-source threshold voltage, making the transistor a conductor. In response to the transistor being conductive, the charge stored in the storage capacitor 140 is fed to the actuator 120, and the RF-EH system stores the harvested energy in the storage capacitor. If the amount of charge is sufficient, the actuator 120 is activated.

[0127] Figure 5B A consumable package 501 is shown, comprising a cardboard box outer frame 502, a hinged cover 503, an inner liner 504, and consumables 505. Figure 5A Circuit 500, shown as 510, has a variable capacitor 546 and no actuator 120 embedded in the container. Actuator 120 in Figure 5 may correspond to actuator 511. In this example, the actuator may be a vibration device. When the user's hand holds or presses the package, and thus presses the variable capacitor of circuit 510, as... Figure 5BAs shown on the right, the actuator is triggered and can provide a sensed vibration 514.

[0128] Depending on various aspects, the container may include circuitry corresponding to or being at least one of circuits 100, 200, 300, and 500. The container may be packaging and may be configured to store consumables, devices, or accessories. The circuitry, or at least a portion thereof, may be embedded within the container. Depending on various aspects, the circuitry may be more complex than circuits 100, 200, 300, and 500. For example, the circuitry may include an oscillator circuit. The oscillator circuitry may include one or more transistors, one or more resistors, and one or more capacitors. The oscillator circuitry may be configured to generate a periodic wave when fed with energy from an energy storage device. The periodic wave may include a sine wave, a square wave, or a combination thereof. The oscillator circuitry may be connected to an amplifier circuitry for driving a speaker to produce sound when triggered. For example, the circuitry embedded in the container may be configured to produce a sound, such as a "humming" sound, when triggered (e.g., by opening the container). This sound may be associated with a user's sensation.

[0129] Figure 1 , 2 The energy storage unit of the RF-EH system, which is capacitor 140 as detailed in 3 and 5A, will be shown separately from the RF-EH system to better understand how the energy stored in capacitor 140 is triggered and fed to the actuator. Figure 1 , 2 Figures 3 and 5A only show the main components of the corresponding circuits to provide a schematic diagram of how the circuits work. Figure 1 , 2 The circuits for 3A and 5A may include additional components, including at least one of resistors, capacitors, diodes, etc. These additional components can be used to clean or filter signals. Figure 1 , 2 The grounding for the 3A and 5A circuits can be provided by the inner lining of the packaging, which can be aluminum foil encapsulating the consumables.

[0130] Figure 6A schematic diagram of an RF-EH system 600 for powering actuator 120 is shown. A container may include the RF-EH system 600 to power actuator 120. The RF-EH system includes an antenna 610. The antenna 610 of the RF-EH system 600 may be printed on at least one surface of the container. The antenna 610 of the RF-EH system 600 may be a layer of packaging material of the container. The antenna 610 of the RF-EH system 600 may be included in at least one wall of the container. The antenna 610 of the RF-EH system 600 may be deposited in the cardboard of the container. The antenna 610 of the RF-EH system 600 may be included in the liner of the container. The liner comprises metal. The antenna 610 of the RF-EH system 600 may be configured to receive ambient RF signals (such as signals from wireless networks, mobile phones, or television stations). The RF-EH system 600 may be embedded in the container at the factory. Radio frequency energy harvesting (“RF-EH”) allows electrical energy to be generated from ambient or surrounding RF signals. This energy can be used to power at least one of the actuators and the tag.

[0131] The RF-EH system can be connected to very small and low-cost actuators that require no batteries or maintenance. The RF-EH system 600 can be configured to harvest and store energy from ambient RF signals. The RF-EH system may include an antenna 610, an impedance matching circuit 620 that allows maximizing power transfer from the antenna 610 to the load (which can be achieved when the load impedance equals the source impedance), a rectifier circuit 630 that allows AC to DC conversion for energy storage, and an energy storage device 640, which may be a capacitor acting as an energy reserve. Alternatively, the energy may be stored in a battery.

[0132] The stored energy can be used for a variety of applications, including powering actuators or backscattering signals (such as incoming RF signals).

[0133] Figure 7 A schematic diagram of a container including tag 722 is shown according to various aspects. Tag 722 can be configured to "backscatter" an RF signal, such as RF signal 730. The backscatter signal may include a radio frequency signal with added information transmitted back by modulating the frequency or amplitude of the carrier wave of the incoming RF signal. This can be achieved by adjusting the impedance or capacitance of the RF-EH system that powers the tag. The tag may be an RFID (Radio Frequency Identification) tag.

[0134] Passive communication techniques can be used to backscatter incoming RF signals. However, these techniques are limited in the amount of power they can radiate back. For a given wireless power source, the power at the receiving antenna decreases sharply with distance. An RF energy harvesting system 600 can be coupled to an RFID tag to use an additional amount of energy to improve the range of the RF backscattered by the RFID tag. A complete "RF-EH tag" in this application includes an RF energy harvesting system combined with RFID circuitry or the tag.

[0135] The frequency range of the acquired signal can be wider than the backscattered RF range, allowing the RF-EH tag to acquire and store energy from multiple environmental sources and use this stored energy to improve the backscattering of RF signals that belong only to a narrower RF range used by dedicated devices, such as the RF range used by electronics communicating with the tag. The antenna used for acquisition can be designed to receive a wider frequency range than the antenna used for backscattering incoming RF signals.

[0136] Figure 7 A schematic diagram of a tag 722 according to one aspect is shown. The tag 722 may be included in a container. The tag 722 may be powered by an RF-EH system (such as RF-EH system 600). The tag 722 may include a load modulator 710. The load modulator 710 may use a first load 712 and a second load 714 to modulate an input signal 730. The tag 722 may be configured to use amplitude modulation to backscatter the RF input signal 730, which includes a carrier wave. The tag 722 may be configured to modify the RF input signal such that the backscattered signal includes tag-specific data. The tag-specific data may include an identification value of the container. The tag may be in an absorptive state, where the incoming carrier data signal is completely absorbed, such that 0 is backscattered, or in a reflective state, where 1 is backscattered. The tag 722 can change from an absorptive state to a reflective state by adjusting the impedance of the input RF signal, respectively matching or dismatching it. Alternatively, the tag 722 may use frequency modulation.

[0137] By using the harvested energy, the backscattered RF signal can range up to tens of meters indoors, allowing users to separate the container and the electronic device from each other or place them at a certain distance while still being able to authenticate the container. For example, an office user can remove the consumable from the packaging, put the packaging back in a bag or coat that may be several meters away, move back to his / her desk, insert the consumable into the electronic device, and then simply activate the electronic device, triggering the RF signal used for packaging authentication that will still be backscattered by the packaging.

[0138] The surface of the container can be used for the antenna 720 of the RF-EH system. The antenna 720 ensures proper RF feed and allows energy to be charged into the RF-EH system. The antenna can be "printed" inside the container or packaging, or, if it is laminated, on a layer of packaging material.

[0139] The input RF signal 730, including the carrier wave, can be provided by an electronic device. The electronic device can be a smartphone or an aerosol generating device. The backscattered signal can be read by the electronic device. In response to the backscattered signal, the electronic device can prevent the use of consumables by the electronic device or another electronic device.

[0140] The container's RF-EH system can be "charged" at factory time using a flexible RF transmitter. Even if the container remains unused for a slightly longer period before being used, the RF-EH system can still function and provide power to actuators or tags, provided an ambient RF signal is present. However, if the RF-EH does not have enough power to provide a signal, a user can be invited to activate electronics (e.g., an RF transmitter or smartphone) near the container to charge the embedded RF-EH system, thus allowing the RF-EH system to power the actuators.

[0141] Radio frequency energy harvesting (“RF-EH”) systems are configured to generate electrical energy from ambient or surrounding radio frequency (RF) signals. This energy can then be stored for use. RF-EH can be implemented using very small and low-cost electronic tags that require no batteries or maintenance. RF-EH circuitry can be configured to harvest and store energy from ambient RF signals. An RF-EH system may include four main components: an antenna, an impedance matching circuit that allows maximizing power transfer from the antenna to the load (this is achieved when the load impedance is approximately equal to the source impedance), a rectifier circuit that allows AC to DC conversion for storage, and an energy storage device, such as a capacitor configured to act as an energy reserve. The stored energy can be used in a variety of applications. RF-EH systems in multiple packages can be “charged” at factory time using a flexible RF transmitter. The surface of the container or packaging can provide an area for the antenna of the RF-EH system. The antenna can be “printed” inside the packaging. The antenna can be on layers of packaging material that can be laminated. The antenna can be formed from a profile cut into the metal liner of the packaging. For example, the antenna can be cut into the aluminum foil used to encapsulate consumables.

[0142] To achieve maximum power transfer between the source and load, the impedances of the load and source must be matched. To correct for impedance mismatch between the load and source, a transformer can be used. A transformer is a passive device that may include two coils joined by magnetic cores, configured to transfer energy from the source to the load using electromagnetic induction while balancing their mutual impedances. This can be achieved by adjusting the number of turns in the primary and secondary coils such that the square of the ratio of the number of turns equals the ratio of the impedances of the source and the load.

[0143] Figure 8 An exemplary circuit including a transformer 810 is shown, which is used to match the impedance of an AC source (which may be an antenna 820). and the impedance of the load 830 To match the source and load impedances, the transformer can be based on... To configure, among which It is the number of turns in the primary winding of the transformer, and It refers to the number of turns in the secondary winding of the transformer.

[0144] The rectifier circuit is configured to convert AC voltage to DC voltage. An RF-EH system may include a rectifier circuit configured to convert signals received by an antenna into DC for energy storage.

[0145] Figure 9 A half-wave rectifier 900 is shown, comprising a capacitor 920 and a diode 910. When the alternative source 930 is in the conducting phase of the diode 910, it supplies energy to the load 940. In the opposite phase, the diode 910 prevents current from flowing towards the source. When discharging, the capacitor 920 continues to supply current to the load, even when the source is not supplying it.

[0146] Figure 10 An example of a full-bridge rectifier is shown. The bridge of diodes D1 to D4 is configured to keep the current in the same direction independently of the stage of the alternative source 1030.

[0147] Depending on the aspects, at least one actuator includes a low-power optical system actuator, such as an LED or LED array. The optical system actuator can be configured to provide a light signal directed toward the exterior of the packaging. A human can receive the light signal. The optical system actuator can be configured to provide a light signal directed toward embossing or engraving created on the outer surface of the packaging to provide an enhanced visual effect of the packaging. The optical system actuator can be configured to provide light toward the interior of the packaging to illuminate the contents of the packaging. For example, by opening the container or packaging, the optical system actuator can be configured to illuminate at least a portion of the interior of the container or packaging.

[0148] Depending on the aspects, at least one actuator includes a vibrating device or an array of vibrating devices. The vibrating device may include an eccentric rotating mass, a piezoelectric actuator, a linear resonant actuator, or another vibration technique. The actuator may be configured to provide vibration in response to a user touching the packaging. For example, the action of a user touching the packaging can trigger the actuator. The actuator may be configured to provide a sense of vitality or energy from the packaging, or a slight "gurgling" sound when the packaging is opened, which allows for efficient differentiation of the packaging from other packaging.

[0149] Alternatively or additionally, at least one actuator may include a loudspeaker. Depending on the aspects, at least one actuator may include a combination of two or more different types of actuators. For example, a single RF-EH system may be used to provide energy to LEDs configured to illuminate the interior of the packaging when the packaging is opened, and to provide energy to a vibrating device configured to provide vibration when a force is applied to the packaging.

[0150] Depending on various factors, different types of triggering actions can be combined, and for example, the same actuator can be used. For instance, a single RF-EH system can be used to power LEDs inside the packaging when the packaging is opened. Furthermore, the packaging may have one or more "windows" (i.e., openings in the packaging) that can be illuminated when the same LED is activated, based on the amount of energy stored in the RF-EH system or randomly. This can create a lighting effect that attracts the attention of customers passing by in retail stores, nightclubs, etc.

[0151] Figure 11 A schematic diagram illustrating an example of an RRP consumable is shown. The RRP consumable may include a combination of several rods and may have a cylindrical shape. A first rod 1110 may include a matrix for generating an aerosol upon heating. A front rod 1120 may be configured to protect the first rod from external conditions and may be made of cellulose acetate. An MPF ​​(“mouthpiece filter”) 1130 is configured to be placed between the user’s lips and may have a filtering function. One or more other rods 1140 may include cardboard tube rods, which are tubular rods having a hollow core and walls of cardboard, cardboard, or laminated rigid material, configured to cool hot air from the heated first rod before reaching the user. Other rods may be HAT (hollow cellulose acetate tube) rods or FHAT (fine hollow cellulose acetate tube) rods, which are hollow cellulose acetate tube rods, or PLA rods (rods made of polylactic acid membrane) for cooling.

[0152] Figure 12 A schematic diagram is shown of packaging for assembling and storing consumables, based on various aspects. Figure 12The die-cut 1215 of the cardboard consumable package 1201 is shown in the upper left corner. Package 1201 may have a cardboard outer frame and a hinged lid. The bottom illustration shows a metal liner 1204, which can be used to wrap the consumable 1205. Once the liner is wrapped around the consumable, the RF-EH circuit 1210, connected to the actuator 1211 (here, a DC coin-type vibrating motor), can be attached to the liner before it is inserted into package 1201.

[0153] The user interface is implemented by providing an actuator powered by an RF-EH system within the container. Containers for storing consumables can provide enhanced functionality, namely through lighting and / or sound and / or vibration, which can improve and enhance product differentiation without using physical or chemical power sources (such as batteries) included in the container. This allows for lower manufacturing costs and potentially lower environmental impact, within sustainability limits, compared to systems with batteries.

[0154] According to various aspects, a package is provided for RRP consumables, for devices, or for accessories. The package includes a radio frequency energy harvesting (“RF-EH”) system embedded within the package, and at least one actuator attached to the interior or exterior of the package and connected to the RF-EH system. The at least one actuator may be an LED, a vibration device, or a combination thereof. The RF-EH system is configured to store electrical energy. In response to an action applied to the package or a specific amount of energy stored in the RF-EH system, the stored energy can be fed to the at least one actuator. The RF-EH system, according to various aspects, provides energy to activate the actuator embedded in the package. The at least one actuator may be configured to provide a signal perceptible to humans. The package may include a sensor connected to the RF-EH system. The sensor may be configured to capture the signal. The actuator may be triggered in response to the captured signal.
