    BACKGROUND
    [0003] Traditional true flame candles, when lit, provide a pleasant ambience in many homes, hotels, churches, businesses, etc. Traditional candles, however, provide a variety of hazards including risk of fire, damage to surfaces caused by hot wax, and the possible emission of soot. Flameless candles have become increasingly popular alternatives to traditional candles. With no open flame or hot melted wax, flameless candles provide a longer-lasting, safe, and clean alternative. Such imitation candle devices often include light sources, such as LEDs, and include electronic circuits that control the operation the imitation candle device.

    DETAILED DESCRIPTION OF CERTAIN EMBODIMENTS
    [0021] In this patent document, the word “exemplary” is used to mean serving as an example, instance, or illustration. Any embodiment or design described herein as “exemplary” is not necessarily to be construed as preferred or advantageous over other embodiments or designs. Rather, use of the word exemplary is intended to present concepts in a concrete manner.
    [0022] Imitation candle devices can simulate a real candle with a flame that resembles a real-life flame with flickering effects using optical, mechanical and electrical components. The disclosed embodiments provide further features and functionalities that enhance the operation of these devices, and in some cases, enable additional features that cannot be obtained with real candles.
    [0023] FIG. 1 illustrates an exemplary imitation candle device 102 with an associated remote control device 106 in accordance with an exemplary embodiment. The flame element 104 protrudes upward from the body of the imitation candle device 102, and the top portion 108 of the body is formed to resemble a melted candle wax to enhance the resemblance of the candle device 102 to a real candle. The remote control device 106 is configured to operate with the imitation candle device 102 via a wireless channel. For example, the remote control device 106 can include an infrared transmitter to provide various commands and signals to an infrared receiver of the imitation candle device 102. In some embodiments, other wireless communication protocols and techniques, such as Bluetooth, cellular, WiFi, etc., can be used. In certain applications, the communication channel that allows remote control of the imitation candle device can include a wired communication channel.
    [0024] FIGS. 2(A), 2(B) and 2(C) illustrate some of the components of an exemplary imitations candle device including an enclosure 214 that houses the internal candle components, and a flame element 202 that protrudes from top of the enclosure 214. The flame element 202 includes a hole 208 that allows a support structure 206 to pass through the hole to suspend the flame element 202. The ends of the support structure 206 are secured within slots 216 that are formed on top of the enclosure 214. As shown in the exemplary diagram of FIG. 2(A), the support structure 206 is bent at two ends to fit within the slots 216, and the is slightly bent downwards at the location of the hole 208. The top portion of the enclosure include an indentation to accommodate a plate 210 in the form of an annulus. It should be noted that in other implementations, the plate 210 can include other shapes, such as rectangular or triangular shapes, can be configured to not fully encircle the flame element 202 and/or made smaller or larger in size. As will be described in detail below, the annulus not only operates as a decorative element to hide the internal candle components from plain view and secures the ends of the support structure 206 in place, it also enables touch-sensitive operation of the candle.
    [0025] A light source 212, such as an LED, can be placed inside the enclosure 214, as shown in FIG. 2(C). The light source 212 can, for example, project light of suitable color and/or intensity to the flame element 202. In some implementations, more than one light source 212 is used to illuminate the flame element 202 from one side, and/or from both sides. In some embodiments, the light source 212 can be an incandescent light source, a plasma light source, a laser light source, or can include other suitable light producing mechanisms.
    [0026] FIG. 3 shows additional details of the components of an exemplary imitation candled device that includes a flame element 302 that is suspended by a steel wire support structure 306. The bottom section of the flame element 302 below the steel wire support stmcture 306 can include a magnetic element 320 that interacts with a magnetic field produced by a coil 316. The coil 316 can be energized by control signals generated by electronic circuits that are located on, for example, a PCB board 318. In some implementations, the electronic circuits can generate pulses that cause the electromagnet to turn on and off, to vary the produced magnetic field strength, or to reverse polarity, at particular time instances. In one example, the signals that energize the coil 306 is a pulse-width modulated signal. In other examples, such signals provide an amplitude modulated, a phase modulated or a frequency modulated signal to the coil 306. Due to interactions of the magnetic element 320 with the magnetic field of the coil 306, the flame element 302 can oscillate and produce a flickering effect when illuminated by the light produced by the one or more light source 314. The imitation candle device can further include a wireless receiver component receives and decodes wireless signals transmitted thereto. For example, some components of such a wireless receiver can be located on the PCB board 318, and can operate based on one or more wireless technologies and protocols, such as infrared technology, Bluetooth or cellular protocols.
    [0027] FIG. 3 also illustrates a ring 304 that is positioned on top of the imitation candle housing, around and in the vicinity of the flame element 302. In some embodiments, the ring 304 serves as a decorative piece to hide the internal components of the imitation candle device and/or to resemble melted wax. In this regard, the ring 304 can have a particular color and/or reflectivity to produce the desired visual effect when viewed under ambient illumination, or under the scattered and/or reflected illumination of the candle light source 314. In some embodiments, the ring 304 operates as a touch sensitive on-off switch. In particular, the ring 304 can be made of conductive material that forms a capacitive element in electrical connection with one or more components on the PCB board 318. When a user’s finger contacts, or is within close proximity of, the ring 304, a capacitive contact is formed to complete a circuit. The touch-sensitive mechanism can be used for turning the candle on or off, or for controlling other functions of the imitation candle in a step-wise manner. For example, each touch can increase or decrease intensity of the light source 314, to switch the color of light, or to change a mode of operation (e.g., from flickering to constant intensity).
    In some embodiments, the touch sensitive element (shaped as a ring, or other shapes) includes two segments that are preferably poisoned at two different sides of the flame element on the top surface of the imitation candle device. In such embodiments, the two-piece touch sensitive element is configured to operate as a switch (e.g., conduct a current) only if both segments of the touch sensitive element are touched. For example, a user can touch one segment of the touch sensitive element that is positioned close to, and on one side of, the flame element with his/her thumb, and the other segment of the touch sensitive element that is positioned close to, and on an opposite side of, the flame element with his/her index finger to activate the switch and turn off the imitation candle device. As such, the multi-segment touch element can be used to simulate the appearance that the user is extinguishing the candle flame using his/her fingers.
    [0028] The imitation candle device of FIG. 3 also includes a microphone 310 that is held in place within the interior of the imitation candle device by a microphone support element 308. The microphone 310 converts acoustic signals into electrical signals that are provided to an electronic component on the PCB board 318. The microphone 310 is positioned closer to the top surface of the imitation candle device to intercept sound waves that travel into the interior of the imitation candle device. For example, the top section of the imitation candle device can include an opening (e.g., the same opening that allows light from the light source 314 to reach the flame element 302) that allows the microphone to capture acoustic waves that travel down into the interior of the imitation candle device. In this way, when a user blows in the direction of the imitation flame element 302, the blow is captured by the microphone 310, and the appropriate signals are generated to turn off the imitation candle device.
    [0029] The electrical signals produced by the microphone 310 can be processed by the components of the PCB board 318. The PCB board 318 can, for example, include filters, analog-to-digital circuits and/or a processor or controller (e.g., a microprocessor, a digital signal processor (DSP), an FPGA, an ASIC, etc.) that receive signals representing the captured sound waves. The processor can execute program code stored on a non-transitory storage medium, such as ROM, a RAM or other memory device, to analyze the signals corresponding to the sound waves and to determine that a blow has occurred. Upon detection of a blow, a corresponding signal can be produced to turn off the light source 314 and/or the entire imitation candle device. The program code that is executed by the processor can include an algorithm that differentiates between captured sounds of blowing air and other sounds such as clapping or human conversation.
    [0030] In some embodiments, the blow detection circuitry can be implemented as a separate component from other components of the PCB board 318. For example, the blow detection can be implemented using analog or digital circuits. In some embodiments, to facilitate the detection of a blow, the microphone 310 that is mounted is coupled to an amplifier to generate an AC signal above a predetermined threshold voltage value (e.g., 200 mV), or a within a predetermined range of values (e.g., 200 mV to 3.5 V). Whereas the sound pressure/level due to a blow provides voltage values above such a threshold (or within such predetermined range of values), other sounds, such as a clapping sound, detected by the microphone can only generate an AC signal below the threshold value (e.g., at 20-100 mV), or outside of the predetermined range of values that correspond to the detection of the blow. The resulting signal of the amplifier can be further coupled to a second stage amplifier with a high amplification factor (e.g., 100 to 300 times). In some implementations, the second stage amplifier is a capacitive coupling transistor amplifier that forms a square wave that is provided to the processor to shut down the candle device. If the captured sound wave produces a signal below the threshold, such a signal does not activate the second stage amplifier (e.g., the transistor amplifier), and thus the appropriate signal for shutting down the candle device is not generated. It should be noted that, in the above description, voltage values are provided as examples to facilitate the understanding of the disclosed embodiments. It is, however, understood that other measurements, such as measured current values, may be used for identifying the blow, and/or different ranges of values may be used to effectuate the identification.
    [0031] It should be noted the above description has been provided with reference to an imitation candle device with a moving flame element. It is, however, understood that the use of a microphone for blow detection can be implemented in other imitation candle configurations, such as those that utilize non-magnetic means for moving the flame element, in candle devices with a stationary flame element, or any other imitation candle device that can accommodate a microphone and the associated circuitry. Moreover, in some applications, the disclosed technology may be implanted as part of an imitation fireplace, an imitation candelabra, or other lighting fixtures. Further, in some implementations, a device other than a microphone, such as flow sensor, can be used to detect the blow.
    [0032] As noted in connection with FIG. 1, the disclosed imitation candle devices may be equipped with a remote control device that enables control of variou s candle functionalities from a remote location. An exemplary remote control device 400 is shown in FIG. 4(A). Various buttons on the remote control device 400 enable a user to remotely control various features of one or more associated imitation candle devices. In particular, an on-off button 402 allows the imitation candle device to be turned on or off remotely. The brightness/dimness of the candle device is controlled by two switches, 404(a) and 404(b), that are positioned below the on-off button 402, and the speed of the flickering and/or movement of the candle’s flame element is controlled via switches 406(a) and 406(b). The remote control device 400 further includes one or more timer buttons 408 (e.g., 4-stage timer buttons) that allow the imitation candle device to operate for any one of several timed durations (e.g., a 4-hour, a 6-hour, a 8-hour or a 10-hour duration) before the candle device is automatically turned off. To activate the timer operation, a user can, for example, press the central timer button followed by the desired duration button. The remote control device 400 can also include additional buttons (e.g., a candle selection button, a blow on-off activation button, a wireless coupling button, etc.) to enable additional operations and communications with one or more imitation candle devices.
    [0033] FIG. 4(B) illustrates an exploded view of the components of the exemplary remote control device of FIG. 4(A). An upper cover 401 includes openings that accommodate different buttons, such as a power button 403, a circular button 405 with quad activation sections and one or more timer buttons 407. A flexible layer 409 (such as a silicone sheet) with appropriate stiffness is positioned below the buttons on top of a PCB board 411 that includes electronic circuitry. The remote control device also includes a negative side spring 413 and positive side spring 415 and screws 417. A microphone 419 is placed on a microphone board 429 to capture sounds and to generate electric signals therefrom. The remote control device may also includes a side cover 421 that allows (e.g., through a hole in the side cover 421) an infrared receiver and/or transmitter to communicate with another device. A weight 423 may also be added, as needed, to assist with obtaining the desired weight and/or balance for the remote control device. The bottom cover 425 includes a battery compartment that accommodates one or more batteries and the corresponding battery cover 427.
    [0034] As evident from FIG. 4(B), the remote control device includes a microphone 419 and the corresponding circuit broad 429 that are used for capturing and identifying a blow. FIG. 4(C) illustrates an exemplary location of microphone hole on the top cover of the remote control device. Similar to the above description regarding the imitation candle device, in some embodiments, a user can blow at the remote control device in the vicinity of the microphone hole to control a functionality of the imitation candle device, such as to turn the candle off.
    [0035] FIG. 4(D) illustrates an exemplary circuit diagram associated with the electrical components of the remote control device. The circuit is powered (at VDD) using a battery, such as a CR2032 lithium button battery that supplies a voltage in the range 2.2 to 3.2 V to the chip Ul. In some implementations, the chip U1 includes a microprocessor. It is, however, understood that the chip Ul may include, or be designed as, an FPGA, an ASIC, a DSP, or discrete circuit components. The chip Ul controls various operations of the remote control device, such as detecting that a switch (e.g., one of switches SI to SI0) has been pressed. The chip Ul includes an IRout pin that controls an infrared LED for transmitting an infrared signal to another device. The electric current from the battery is filtered by capacitors C1 and C2 and provided to the IR LED. A microphone (MIC l ) is coupled to a two-stage electronic circuitry, notably transistors Q1 and Q2 and associated biasing and amplification components (e.g., resistors R2-R5). In some embodiments, the chip Ul reaming in an idle operating status when a “high” voltage is present at an input pin that corresponds to a certain functionality, such as an on/off functionality, a timing functionality, a brightness increase functionality, a brightness decrease functionality, a pause/slow/stop flame movement functionality, a fluctuating/fast/start flame movement functionality, a blow detection functionality, and so on. In such embodiments, the chip Ul waits until a low signal occurs. For example, when a blow is directed to the microphone hole of the remote control device, a sound a wave having a certain intensity or sound pressure is produced at the head of the microphone. In an exemplary embodiment, such a blow generates an AC signal of about 200 mV or more that is subsequently amplified by 100-300 times, forming square waves that pull the appropriate input of the chip Ul to a low voltage value for a predetermined duration. As a result, the infrared transmitter is activated and a signal is transmitted to the candle device to turn the candle off. Implementing the blow detection circuits as a separate subsystem of the remote control system (as done in the exemplary diagram of FIG. 4(D)) allows the blow detection capability to be added to an existing remote control device without having to redesign the internal circuits or programming of the chip U1. In addition, implementation of the blow detection subsystem in discrete components can allow faster detection speed since additional delays due to processing by the chip Ul are avoided. As noted earlier, the disclosed embodiments also prevent inadvertent activation of this feature based on background noises and unwanted sounds. In some embodiments, the blow detection circuitry and/or associated recognition software instructions can be adapted to cause a fluttering movement of the simulated flame. For example, if the strength of the detected blow is below a particular threshold (e.g., a particular voltage value), the blow can be identified as not being strong enough to extinguish the simulated flame. As such, the detection of such a blow can cause the intensity and pattern of illumination of the flame element to change to simulate a real candle that is fluttering in the wind.
    [0036] It is thus evident that, in one aspect of the disclosed technology, an imitation candle device is provided that includes a body, a flame element protruding from top of the body, one or more light sources positioned to illuminate the flame element to produce an appearance of a true fire flame, a sensor positioned within the body to detect a blow of air directed at the imitation candle device, and electronic circuitry positioned within the body to receive electrical signals produced by the sensor and to modify an output light of the one or more light sources in response to detection of the blow. In one exemplary embodiment, the sensor is a microphone that produces the electrical signals in response to detection of an acoustic wave. In another exemplary embodiment, the sensor is an air flow sensor that produces the electrical signals in response to detection of flowing air in the vicinity of the air flow sensor. In yet another exemplary embodiment, the imitation candle device includes an opening at a top section of the body in the vicinity of the flame element to receive the blow of air and to direct at least a portion of the blow to within the body.
    [0037] According to another exemplary embodiment, the electronic circuitry is configured to differentiate the received electrical signals that are associated with the blow of air from the received electrical signals that are nor associated with the blow of air. For example, the received electrical signals that are not associated with the blow of air can include electrical signals associated with: an ambient noise, a clap, or a human speech. In another exemplary embodiment, the electronic circuitry includes a first stage detection circuit coupled to the sensor to receive the electrical signals produced by the sensor, and a second stage detection circuit having an input that is coupled to an output of the first stage detection circuit. The second stage detection circuit has an output that indicates the detection of the blow in response to receiving a voltage or a current value within a predetermined range from the first stage detection circuit. For example, the first stage detection circuit produces an output in the predetermined range upon detection of the electrical signals that correspond to the blow, and produces an output that is outside of the predetermined range upon detection of the electrical signals that do not correspond to the blow.
    [0038] In still another exemplary embodiment, the electronic circuitry, in response to detection of the blow, turns off one or more of the light sources. In yet another exemplary embodiment, the electronic circuitry, in response to detection of the blow, turns off the imitation candle device. In some embodiments, the electronic circuitry is configured to turn off the imitation candle device in response to detection of the blow for a predetermined duration of time. In yet another embodiment, the imitation candle device further includes a touch sensitive component positioned on, or close to, an outer surface of the body to sense a touch and to produce an electrical signal in response to the detected touch that turns the imitation candle device, or the one or more of the light sources, on or off. According to another exemplary embodiment, the touch sensitive component is shaped as an annulus that encircles the flame element.
    [0039] In some exemplary embodiments, the imitation candle device further includes a remote control device that is configured to transmit a signal to the electronic circuits to control one or more operations of the imitation candle device. In one exemplary embodiment, the remote control device includes an electronic circuit board and a microphone coupled to the electronic circuit board. The microphone is positioned to intercept sounds through an opening on the remote control device, to produce an electrical signal in response to the detected sounds, and to provide the electrical signals to a component on the electronic circuit board. For example, the component on the electronic circuit board can includes a two-stage detection circuitry having an output that indicates the detection of a blow of air in response to detecting a voltage or a current value within a predetermined range.
    [0040] In some exemplary embodiments, the remote control device further comprises a wireless transmission device that is activated to produce a signal for transmission to a receiver device within the body of the imitation candle device upon detection of the output that indicates the detection of a blow of air. For example, the wireless transmission device can include one or more of: an infrared transmission device, a Bluetooth transmission device, or a cellular transmission device.
    [0041] In some embodiments, the remote control functionalities and features are implemented as a application on an electronic device, such as a smart phone, a tablet, a laptop or similar devices. Such an application enables different features to be implemented in a user-friendly manner on a graphical user interface (GUI), and further facilitates the addition of new features and/or improvements via software updates. FIGS. 5(A) to 5(C) provide exemplary user interface screens of one exemplary application. For example, as shown in FIG. 5(A), the application can determine as to whether or not a particular imitation candle device is within the range of communication, and provides an indication if the application is unable to establish a link with one or more candles. For example, such a link can be established via Bluetooth. The application further enables a user to select a particular candle device among a plurality of candle devices, as shown in FIG. 5(A)’s selection of Matrix Candle 1. As further shown in FIG. 5(A), once a particular candle device is selected, the user interface allows the selected candle to be turned on or off by selecting the on-off button, and activating the button as needed.
    [0042] FIG. 5(B) illustrates activation of additional functionalities through the user interface. In particular, in the exemplary user interface screen in FIG. 5(B), the timer selection option allows setting of a start time, an end time and repetition period. The timer setting can further be customized to activate the desired feature on particular days of the week (e.g., by clicking on or highlighting the particular day(s) of interest on the menu of the user interface). The remote application further allows the selection of an appropriate candle light intensity by, for example, clicking on one of the segments of the depicted light wheel. Such a selection allows adjustment of light intensity in order to, for example, accommodate different moods and/or different ambient lighting conditions. The movement of the flame element can also be controlled via the remote application, by, for example, selecting an amount of flicker on a sliding bar that ranges from full flicker to an appearance of a static flame. Additional control features (e.g., via a second sliding bar) may also be provided to control the speed of flickering. Upon selection of the appropriate level of light intensity and/or flame movement, the appropriate control signals are generated at the remote control device and transmitted to the imitation candle device. Upon reception of such control signals, the imitation candle device adjusts or activates/deactivates the selected features.
    [0043] FIG. 5(C) illustrates additional exemplary operations and selection capabilities of the remote control application. For example, selection of an item on the Main Menu (e.g., Home, Blow Out, news, Profile, About and Privacy) allows the user to navigate through the corresponding menu item. One feature of the disclosed remote application enables the selection of a group of candle devices. Such a group can, for example, be formed by selecting individual candle devices to be part of the group, and assigning a group name (e.g., by typing a desired group name). Once a group is formed, various functionalities of the candle devices within the group can be activated and/or adjusted. For example, as shown in FIG. 5(C), group timer selection, group time settings, group light intensity selection and group flame movement selection can be made in a similar manner as described in connection with an individual candle device. Additionally, if desired, a single disconnect button on the user interface can sever communications with all devices within the group or groups.
    [0044] The blow on-off functionality can also be activated via the user interface by selection the Blow Out item on the main menu (see FIG. 5(C)). Once the blow out functionality on the remoted device is activated, the application can provide a notification to the user (see FIG. 5(D)) that the candle device can be turned off by blowing into the microphone of the electronic device (e.g., a mobile phone). The candle application receives the signals that are produced by the device’s microphone, and upon detection of the blow, generates an appropriate signal for transmission to the candle device. The candle device, upon receiving the signal from the remote control device, turns the candle off. In some implementations, the blow is detected by processing the intensity and/or pattern of data that is received from the microphone to distinguish and prevent ambient or unwanted sounds from inadvertently generating a blow off signal. Such a processing can, for example, include correlation and pattern recognition operations that produce a match only when a pattern and/or intensity of a blow is detected. In some implementations, the detection of the blow is carried out cooperatively between the remote control device and the imitation candle device.
    [0045] In some embodiments, a variety of imitation candle devices (e.g., produced by the same manufacturer) can be operated by a single multi-customized remote control device (e.g., a dedicated remote control device, such as the one illustrated in FIGS. 4(A) to 4(C), or remote control implemented on an electronic device). The function buttons or selections on the remote control device allows a user to control different features of the imitation candle device (e.g., the brightness to dimness, fast to slow movement/flame, different hours of timer) for each of the imitation candle devices individually, or as a group. Such selectivity, greatly enhances the user’s interactions with multiple devices, and enables detailed customization of the desired candle functions for candles that are located in different locations and ambient conditions. In one example, the remote control device is IR-based and can operate on multiple frequencies. In some embodiments, the remote control device is configured to ascertain remote control operating frequencies from other imitation candle products and devices and, once obtained, effectuate remote control of the functionalities of those devices. For example, the remote control device can attempt communicating with an unknown imitation candle device at different operating frequencies in a trial and error fashion until the unknown imitation candle device responds (e.g., turns off). In one example implementation, an infrared remote control candle operates at 32 KHz frequency.
