Detailed Description

The technical solutions of the embodiments of the invention are explained and illustrated below with reference to the drawings of the embodiments of the invention, but the embodiments described below are only preferred embodiments of the invention, and not all embodiments. Based on the embodiments in the implementation, other embodiments obtained by those skilled in the art without any creative effort belong to the protection scope of the invention.

In the following description, the terms such as "inner", "outer", "upper", "lower", "left", "right", etc., which indicate orientations or positional relationships, are used for convenience in describing embodiments and simplifying descriptions, but do not indicate or imply that the referenced devices or elements must have a particular orientation, be constructed and operated in a particular orientation, and thus, should not be construed as limiting the invention.

As shown in fig. 1 to 9, the present embodiment is a suction nozzle component 2, fig. 1 to 3 are schematic views of the suction nozzle component 2 mounted on a housing 1 of an atomizer, the suction nozzle component 2 of the present embodiment includes an atomized liquid inlet 201 and an atomized liquid outlet 202, an atomized liquid channel is formed between the atomized liquid inlet 201 and the atomized liquid outlet 202, a main air inlet 203 is further provided on the suction nozzle component 2, the main air inlet 203 is communicated with the atomized liquid channel, and in a normal spraying state, the atomized liquid generated by the atomization unit 240 (fig. 12) on the atomizer enters the atomized liquid channel from the atomized liquid inlet 201 and is discharged from the atomized liquid outlet 202, the mouth of the human body is butted with the atomized liquid outlet 202, so as to suck the atomized liquid into the body, in this embodiment, at least one temporary liquid storage tank 21 is provided in the nozzle part 2, and when the condensed water drops of the atomized liquid reversely flow back to the atomized liquid inlet 201, at least part of the condensed water drops of the atomized liquid flow back into the temporary liquid storage tank 21.

An atomized liquid channel is arranged in the suction nozzle part 2, when the amount of atomized liquid in the suction nozzle part 2 is large, some small-volume droplets can be condensed into larger-volume droplets, when the atomizer shakes or changes position, the droplets condensed from the atomized liquid in the suction nozzle part 2 can have backflow phenomenon, namely can possibly flow back to the atomized liquid inlet 201, the atomized liquid inlet 201 is butted with the atomizing unit 240, if the droplets flow back to the atomized liquid inlet 201, the droplets can flow onto the atomizing unit 240 with high probability, so that accumulated liquid is formed on the atomizing unit 240, in the embodiment, a temporary liquid storage tank 21 for reducing or slowing down the backflow of the condensed droplets to the atomized liquid inlet 201 is arranged in the suction nozzle part 2, after the design, when the atomized liquid flows back, at least part of the atomized liquid can flow back to the temporary liquid storage tank 21, so that the atomized liquid flowing back to the atomized liquid inlet 201 can be obviously reduced, the probability of generating liquid loading on the atomizing unit 240 is reduced.

As shown in fig. 4 to 5, the nozzle part 2 in the present embodiment has a substantially elongated cubic shape, the nozzle part 2 includes a first end wall 200a and a second end wall 200b opposite to each other, the atomized liquid inlet 201 is located at the first end wall 200a, and the atomized liquid outlet 202 is located at the second end wall 200b, as shown in fig. 6 and 7, the temporary reservoir 21 is located at the first end wall 200a together with the atomized liquid inlet 201, and the temporary reservoir 21 and the atomized liquid inlet 201 are located at the first end wall 200a together, so that the structure of the temporary reservoir 21 does not disturb the airflow direction inside the nozzle part 2, and if the temporary reservoir is located on other inner surfaces, there is a potential risk of disturbing the airflow, and of course, if the air flow is not considered to be disturbed, in other embodiments, the temporary reservoir 21 may be located on other inner side surfaces.

In addition, for better shunting liquid storage, the atomized liquid inlet 201 is located in the middle of the first end wall 200a, and the two temporary liquid storage tanks 21 are located on two different sides of the atomized liquid inlet 201, so that condensed water drops can be more uniformly shunted to two sides when flowing back, and cannot be intensively reflowed into one temporary liquid storage tank 21, and the shunting effect is better.

In addition, in order to further enhance the backflow prevention effect of the condensed water droplets, the inner side surface of the suction nozzle part 2 is provided with a blocking member 22 for blocking the condensed water droplets from flowing back to the atomized liquid inlet 201. After the blocking member 22 is provided, when the condensed water drops flow back from the atomized liquid outlet 202 to the atomized liquid inlet 201, the water drops are blocked by the blocking member 22, so as to prevent or delay the water drops from flowing to the atomized liquid inlet 201, and the structure and shape of the blocking member 22 may be various, and one is particularly preferred in this embodiment, as shown in fig. 6 and 7.

In this embodiment, the blocking member 22 includes the drainage groove provided on the inner side surface of the suction nozzle part 2, one end of the drainage groove extends toward the temporary liquid storage tank 21, the drainage groove is equivalent to cut off the smooth inner surface side of the suction nozzle part 2, when water drops flow back to the drainage groove, if the amount is small, the water drops are guided into the temporary liquid storage tank 21 along the edge of the drainage groove, and if the amount is large, the water drops directly enter the interior of the drainage groove and are then guided into the temporary liquid storage tank 21.

In order to further prevent the condensed water droplets from flowing back to the atomizing unit 240, the present embodiment also improves the atomizing liquid inlet 201, in the normal spraying state, the side of the suction nozzle part 2 facing the housing 1 is a bottom wall 200d, and the opening of the atomizing liquid inlet 201 penetrates downward from the end wall of the suction nozzle part 2 to the outer surface of the bottom wall 200d of the suction nozzle part 2. With the above design, when the water drops flow back to the atomized liquid inlet 201, some water drops directly flow out from the bottom wall 200d and do not flow onto the atomizing unit 240, so that less liquid loading is generated on the atomizing unit 240.

In addition, in the present embodiment, it is preferable that an auxiliary air inlet 204 is formed to penetrate through the inner surface of the suction nozzle part 2 in addition to the main air inlet 203 formed in the suction nozzle part 2, and the auxiliary air inlet 204 is formed to contribute to increase the amount of intake air, and that a blocking effect is also provided to block the backflow of water droplets by penetrating one auxiliary air inlet 204 through the inner surface. In the present embodiment, as mentioned above, the blocking member 22 includes two drainage grooves, the two drainage grooves respectively extend from two sides of the auxiliary air inlet 204 to the temporary liquid storage tank 21, in the present embodiment, the auxiliary air inlet 204 and the two drainage grooves together form an isolation region, the atomized liquid inlet 201 is located just in the isolation region, and the temporary liquid storage tank 21 is also located outside the isolation region, so that when the water drops flow back towards the first end wall 200a, the water drops are substantially blocked outside the isolation region, and do not substantially enter the isolation region.

In addition, in the present embodiment, the main air inlet 203 of the suction nozzle part 2 is preferably provided in the bottom wall 200d of the suction nozzle part 2, and the main air inlet 203 is through the inner surface of the bottom wall 200d of the suction nozzle part 2, and the main air inlet 203 in the present embodiment is located at a relatively middle position, so that in fact, when the water drops flow back, the main air inlet 203 can block the water drops on the bottom wall 200d of the suction nozzle part 2 and guide the water drops to flow to the temporary reservoirs 21 on both sides.

In addition, the present embodiment also improves the forward flowing direction of the water droplets in the nozzle part 2, where the forward flowing direction refers to the direction from the atomized liquid inlet 201 to the atomized liquid outlet 202, and as described above, the atomized liquid is easily condensed into larger water droplets in the nozzle part 2, and the nozzle part 2 is often inclined toward the user during normal use, so the water droplets also have the possibility of flowing toward the atomized liquid outlet 202, and the atomized liquid outlet 202 is directly butted with the user's mouth, so the water droplets may directly flow into the user's mouth, which may not achieve good therapeutic effect, and the user experience is not good.

Therefore, in order to solve the technical problem, in the present embodiment, the outlet flow blocking part 23 is disposed on the inner surface of the bottom wall 200d of the suction nozzle part 2, and it should be noted that the description of the top wall 200c and the bottom wall of the suction nozzle part 2 is based on the reference of the suction nozzle part 2 in the normal spraying state. When the droplets formed by condensation of the atomized liquid flow to the atomized liquid outlet 202 and are blocked by the outlet flow blocking part 23, most of the droplets still remain inside the suction nozzle part 2 and do not flow into the mouth of the user after the outlet flow blocking part 23 is provided, which is specifically referred to fig. 8 and 9.

Specifically, in this embodiment, the outlet flow blocking part 23 includes an outlet flow blocking rib protruding from the inner surface of the bottom wall 200d of the nozzle part 2, and the protruding outlet flow blocking rib can achieve a good flow blocking effect. In addition, the protruding height of the outlet flow blocking convex rib is preferably 1mm to 6mm, the protruding height is too low, the flow blocking effect is not good, the protruding height is too high, and the air flow in the suction nozzle part 2 is disturbed, so that the protruding height is preferably 3mm, 4mm and the like.

It should be noted that, the outlet flow-resisting part 23 in this embodiment may also be an outlet flow-resisting groove provided on the inner surface of the bottom wall 200d of the suction nozzle part 2, the structure of which is similar to the drainage groove described above, and the function of which is equivalent to dividing the smooth inner surface of the suction nozzle part 2, so that the flow-resisting effect can be achieved to a certain extent, when the outlet flow-resisting part 23 is the outlet flow-resisting groove, the depth of the outlet flow-resisting groove is 1mm to 5mm, the depth is too shallow, the flow-resisting effect is not good, and the depth is too deep, so that the requirement on the wall thickness of the suction nozzle part 2 is too high, and is preferably 2mm or 3 mm.

With the shape of the atomized-liquid outlet 202 of the suction nozzle part 2 of the embodiment, the shape of the atomized-liquid outlet 202 of the embodiment is designed to match the outer shape of the suction nozzle part 2 and to be rectangular, but considering that the mouth of some children is small, the use of such a rectangular atomized-liquid outlet 202 is not comfortable, and the shape of the atomized-liquid outlet 202 may be appropriately changed, for example, to be oval as shown in fig. 11.

In addition, meanwhile, as mentioned above, in order to enhance the air intake amount, in the present embodiment, the auxiliary air inlet 204 is penetrated through the inner side surface of the suction nozzle part 2, more specifically, the main air inlet 203 is preferably arranged on the bottom wall 200d of the suction nozzle part 2, while the auxiliary air inlet 204 is preferably arranged on the top wall 200c of the suction nozzle part 2, the purpose of arranging the auxiliary air inlet 204 on the top wall 200c of the suction nozzle part 2 is to increase the air intake amount and help to push the air flow to flow, meanwhile, because the air inlets are arranged on both the top wall 200c and the bottom wall 200d of the suction nozzle part 2, the air flow in the suction nozzle part 2 is more concentrated on the middle area between the inner surface of the top wall 200c and the inner surface of the bottom wall 200d, so that the atomized liquid is far away from the top wall 200c and the bottom wall 200d of the suction nozzle part 2 as far as possible, and thus the atomized liquid can reach the user's mouth more rather than being adsorbed on the inner surface of the suction nozzle part 2, see in particular the schematic gas flow diagram of fig. 9.

The auxiliary air inlet 204 is arranged on the top wall 200c of the suction nozzle part 2, and the purpose is to increase the air intake, but in practice, many test experiments show that the auxiliary air inlet 204 is arranged at the position, and can also play an unexpected effect, the diameter of the gaseous liquid bead of the existing atomized liquid is basically between 1 micron and 5 microns, and the really effective liquid bead is about 3 microns, because when the gaseous liquid bead is about 1 micron, the diameter is too small, the user can easily breathe with the breathing action and exhale without well entering the body, when the gaseous liquid bead is about 4 microns, the gaseous liquid bead can only reach the throat part of the human body, and when the gaseous liquid bead is about 5 microns, because the diameter is larger, the liquid bead can only stay in the mouth basically and can not be well inhaled into the lung of the human body, which is found in practical tests, the gaseous liquid beads with the diameter of about 3 microns are most suitable and effective, can be inhaled into the lung of a human body, and are not easy to be exhaled along with the breathing action.

In the embodiment, after the auxiliary air inlet 204 is disposed on the top wall 200c of the suction nozzle part 2, in many actual tests, it is found that most of the gaseous liquid droplets of the atomized liquid discharged from the atomized liquid outlet 202 are concentrated at about 3 microns, and the atomized liquid is easily inhaled into the lung of a human body, so that the treatment effect of the atomizer can be remarkably improved.

In addition, it is known from many tests that the auxiliary air inlet 204 is preferably disposed on a side close to the atomized liquid inlet 201, and it is considered that the maximum distance D1 between the auxiliary air inlet 204 and the first end wall 200a is not more than 4.5cm, and after exceeding 4.5cm, the droplets of about 3 microns in the gaseous liquid generated by the atomized liquid outlet 202 are obviously reduced.

Meanwhile, the minimum distance D2 between the auxiliary air inlet 204 and the first end wall 200a is not less than 1.2cm, and the minimum distance cannot be too small, otherwise, in a normal spraying state, the auxiliary air inlet 204 of the top wall 200c of the suction nozzle part 2 is covered by the housing 1, and does not play a role of auxiliary air inlet.

In addition, the shape of the auxiliary air inlet 204 is D-shaped in the present embodiment. Through practical tests, the auxiliary air inlet 204 with the shape is used for generating more stable air flow in the suction nozzle part 2 and generating more gaseous liquid beads with the diameter of about 3 microns. Of course, in other embodiments, the shape may be rectangular, oval, triangular, etc.

Example two

As shown in fig. 10, the blocking member 22 in this embodiment is not a drainage groove, and the blocking member 22 in this embodiment is a drainage rib, and when the condensed water drops reversely flow back, the condensed water drops are blocked by the drainage rib, so that the effect of blocking the water drops from flowing back toward the atomized liquid inlet 201 is also achieved.

In addition, in the present embodiment, the auxiliary air inlet 204 is not disposed on the nozzle part 2, and in the present embodiment, the whole flow guiding ribs surround to form an isolation region, that is, for the isolation region, the isolation region can be achieved only by the blocking member 22, for example, in the present embodiment, the isolation region can also be formed by the auxiliary air inlet 204 and the blocking member 22 together, for example, as shown in the first embodiment.

EXAMPLE III

As shown in fig. 1 to 3, the present embodiment is a portable atomizer, which includes a housing 1, the housing 1 is provided with an atomizing unit, the housing 1 is further movably mounted with a suction nozzle component 2, in the present embodiment, the suction nozzle component 2 and the housing 1 are detachably mounted, for example, can be butted in a magnet adsorption manner. In the present embodiment, the nozzle part 2 is the nozzle part 2 as in the first embodiment or the second embodiment or equivalent thereto, and the atomized liquid inlet 201 is in butt joint with the atomization unit 240 in a normal atomization state.

The atomizer in this embodiment is a portable atomizer because it is very convenient for the user to carry. Specifically, the housing 1 is provided with a receiving groove 101, the nozzle part 2 is received in the receiving groove 101 when the atomizer is in a non-spraying state, and the nozzle part 2 is opened and forms a working angle α with respect to the housing 1 when the atomizer is in a spraying state. That is, the suction nozzle part 2 can be stored in a non-spraying state, the volume of the whole atomizer is not increased, the whole atomizer is kept in a small state, and when the atomizer needs to be used, the operation can be performed by opening the suction nozzle part 2, and the atomizer can be used by a user at any time and any place, and is very convenient.

It should be noted that the atomizer in this embodiment is also relatively freely usable at an angle, specifically, at the operating angle α of 70 ° to 95 ° in the storage state, the atomizer is relatively easy to use by the user without being twisted, and specifically, see fig. 3.

Fig. 12 is a block diagram of the atomizing unit 240 according to the embodiment. The nebulizing unit 240 includes a Printed Circuit Board (PCB)250 communicatively coupled to a Piezoelectric Disc Assembly (PDA) 260. Other components such as power supplies are omitted for clarity. The PCB 250 may be implemented using the software architecture 406 (fig. 14) and the machine 500 (fig. 15). The PCB 250 includes an impulse cleaning module 251, a misting module 252, a measurement module 253, a frequency scanner 254 system setup 255, and a communication module 256. The frequency scanner 254 uses a frequency sweep approach to determine the resonant frequency of the PDA 260. Upon turning on the misting unit 240, the impulse cleaning module 251 first sends an impulse signal to the PDA 2601 to 3 seconds at a power 20% higher than the target operating frequency shown in the system setting 255 to clean the PDA260 and help ensure optimal and consistent performance.

The nebulizing module 252 then sends the appropriate frequency and amount of power to the PDA260 as indicated by the system settings 255. The appropriate frequency is determined by identifying the resonant and anti-resonant frequencies of the PDA 260. Suitably the frequency value is higher than the value of the resonance frequency by about 10% of the difference between the resonance frequency and the anti-resonance frequency.

Setting the proper frequency for PDA260 is preferably not at the resonant frequency of PDA260, as it can damage PDA260 and shorten its life. The resonant frequency also consumes the most power. This way the frequency can be set exactly just above the resonance frequency: increasing battery life and operating life of PDA260 and making PDA260 less power consuming.

As the frequency scanner 254 sweeps different frequencies onto the PDA260, the measurement module 253 determines the resonant and anti-resonant frequencies by measuring the impedance of the PDA 260. The measurement module 253 measures the voltage and current when different frequencies are applied. PDA260 is considered equivalent to an RLC circuit having impedance as a measurable characteristic.

The minimum impedance is the maximum power level used by the PDA and occurs when the PDA is at its resonant frequency. The maximum impedance is the minimum level of power used by the PDA and occurs when the PDA is at its anti-resonant frequency. These values may be stored in the system settings 255 for later use and/or updated periodically at each power-on.

The communication module 256 sends information regarding the activity of the nebulizing unit 240 to other devices with which it is paired in one embodiment via bluetooth or other communication protocols. This information may include the date, time, number of on/off times, etc. of the time the nebulizer was used. The date and time may be reset or updated each time the nebulizer is paired with another device.

Further, the communication module 256 may indicate that the battery is low, even if the remaining charge is at least 10 minutes longer. In this way, adequate treatment can be performed even if the user is unaware that the battery power of the device is low. This provides the user with the opportunity to recharge the nebulizer after the user has received the last complete treatment from the nebulizer. The atomizer can provide about 15-20 atomizers. Accordingly, when the battery has about 15% capacity left … …, which is about the charge for at least 1 puff, the communication module will indicate that the battery is low, such as by an LED light.

Fig. 13 is a flow diagram of a method (300) of using the nebulizing unit 240 according to an embodiment. As described above, the method determines 310 the resonant frequency of the PDA. Next, a pulsed signal is sent 320 to the PDA, which is higher than the resonant frequency by about 10% of the frequency difference between the resonant and anti-resonant frequencies. The liquid is then atomized 330 at the appropriate frequency as described above. The method 300 may further include implementing the data communication 340 as described above and/or providing 350 a low battery alert as described above. The method 300 then ends.

For example, some mobile or dedicated operating systems may not provide the framework/middleware 418, while other operating systems may provide such layers. Other software architectures may include additional or different layers.

Operating system 402 may manage hardware resources and provide general-purpose services. Operating system 402 may include, for example, a kernel 422, services 424, and drivers 426. The kernel 422 may act as an abstraction layer between hardware and other software layers. For example, kernel 422 may be responsible for memory management, processor management (e.g., scheduling), component management, networking, security settings, and the like. Services 424 may provide other general services for other software layers. The driver 426 is responsible for controlling or interfacing with the underlying hardware. The driver 426 includes, for example, a display driver, a camera driver,

a drive, a flash drive, a serial communication drive (e.g., a Universal Serial Bus (USB) drive),

drivers, audio drivers, power management drivers, etc., may depend on the hardware configuration.

The library 420 provides a common infrastructure used by the application 416 and/or other components and/or layers. The functionality provided by the library 420 allows other software components to perform tasks in a manner that is simpler and easier than interfacing directly with the underlying operating system 402 functionality (e.g., kernel 422, services 424, and/or drivers 426). The library 420 may include a system library 444 (e.g., a C-standard library), which system library 444 may provide functions such as memory allocation functions, string manipulation functions, mathematical functions, and the like. In addition, the libraries 420 may include API libraries 446 such as media libraries (e.g., libraries for supporting the rendering and manipulation of various media formats (such as MPEG4, h.264, MP3, AAC, AMR, JPG, PNG)), graphics libraries (e.g., OpenGL frameworks that can be used to render 2D and 3D with graphical content on a display), database libraries (e.g., SQLite that can provide various relational database functions), web libraries (e.g., WebKit that can provide web browsing functions), and so forth. The library 420 may also include a wide variety of other libraries 448 to provide many other APIs to the application 416 and other software components/modules.

Framework/middleware 418 (also sometimes referred to as middleware) provides a high-level, general-purpose infrastructure that can be used by applications 416 and/or other software components/modules. For example, the framework/middleware 418 may provide various Graphical User Interface (GUI) functionality, advanced resource management, advanced location services, and the like. The framework/middleware 418 can provide a broad spectrum of other APIs that can be used by the application programs 416 and/or other software components/modules, some of which can be specific to a particular operating system 402 or platform.

The application programs 416 include built-in applications 438 and/or third party applications 440. Examples of representative built-in applications 438 may include, but are not limited to, a contacts application, a browser application, a reader application, a location application, a media application, a messaging application, and/or a gaming application. The third party application 440 may include the use of ANDROID by an entity other than the vendor of the particular platform^TMOr IOS^TMApplications developed by Software Development Kits (SDKs) and may be in IOSs^TM，ANDROID^TM，

Or other mobile software running on a mobile operating system, such as a mobile operating system. The third party application 440 may invoke the API calls 408 provided by the mobile operating system (e.g., operating system 402) to facilitate the functionality described herein.

The application 416 may use built-in operating system functions (e.g., kernel 422, services 424, and/or drivers 426), library 420, and framework/middleware 418 to create a user interface to interact with system users. Alternatively or additionally, in some systems, interaction with the user may occur through a presentation layer, such as presentation layer 414. In these systems, the application/component "logic" may be separated from aspects of the application/component that interact with the user.

In the present disclosure, a "client device" refers to any machine 500 that interfaces with a communication network 532 to obtain resources from one or more server systems or other client devices. The client devices 102, 104 may be, but are not limited to, mobile phones, desktop computers, laptop computers, PDAs, smart phones, tablets, ultrabooks, netbooks, laptops, multiprocessor systems, microprocessor-based or programmable consumer electronics, game consoles, STBs, or any other communication device a user may use to access the network 532.

a network, another type of network, or a combination of two or more such networks. For example, the network 532 or a portion of the network 532 may include a wireless or cellular network and the coupling may be a Code Division Multiple Access (CDMA) connection, a global system for mobile communications (GSM) connection, or other type of network cellular or wireless coupling. In this example, the coupling may implement any of a number of types of data transmission techniques, such as single carrier radio transmission technology (1xRTT), evolution-data optimized (EVDO) technology, General Packet Radio Service (GPRS) technology, Enhanced Data GSM Evolution (EDGE) technology, third generation partnership project (3GPP) including 3G, fourth generation wireless (4G) networks, Universal Mobile Telecommunications System (UMTS), High Speed Packet Access (HSPA), Worldwide Interoperability for Microwave Access (WiMAX), Long Term Evolution (LTE) standards, other standards defined by various standards-setting organizations, other remote protocols, or other data transmission techniques.

In this context, a "machine-readable medium" refers to a component, device, or other tangible medium capable of storing instructions 510 and data either temporarily or permanently, and may include, but is not limited to, Random Access Memory (RAM), Read Only Memory (ROM), cache memory, flash memory, optical media, magnetic media, cache memory, other types of memory (e.g., erasable programmable read only memory (EEPROM)), and/or any suitable combination thereof. The term "machine-readable medium" shall be taken to include a single medium or multiple media (e.g., a centralized or distributed database, or associated caches and servers) that are capable of storing instructions 510. The term "machine-readable medium" shall also be taken to include any medium, or combination of media, that is capable of storing instructions 510 (e.g., code) for execution by the machine 500, such that the instructions 510, when executed by the one or more processors 504 of the machine 500, cause the machine 500 to perform any one or more of the methodologies discussed herein. Thus, "machine-readable medium" refers to a single storage device or device, as well as a "cloud-based" storage system or storage network that includes multiple storage devices or devices. The term "machine-readable medium" does not include a signal per se.

In this context, a "component" refers to a device, physical entity, or logic having boundaries defined by function or subroutine calls, branching points, APIs, or other techniques that provide partitioning or modularization of particular processing or control functions. Components may combine through their interfaces with other components to perform machine processes. A component may be a packed function hardware unit designed to be used with other components and portions of programs that typically perform the specified functions of the associated function. The components may constitute software components (e.g., code embodied on a machine-readable medium) or hardware components. A "hardware component" is a tangible unit that is capable of performing certain operations and may be configured or arranged in some physical manner. In various example embodiments, one or more computer systems (e.g., a standalone computer system, a client computer system, or a server computer system) or one or more hardware components of a computer system (e.g., a processor or a set of processors 504) may be configured by software (e.g., application 416 or an application portion) to operate as a hardware component to perform certain operations described herein. The hardware components may also be implemented mechanically, electronically, or any suitable combination thereof. For example, a hardware component may comprise dedicated circuitry or logic that is permanently configured to perform certain operations. The hardware component may be a special purpose processor, such as a Field Programmable Gate Array (FPGA) or an Application Specific Integrated Circuit (ASIC). The hardware components may also include programmable logic or circuitry that is temporarily configured by software to perform certain operations. For example, the hardware components may include software executed by the general-purpose processor 504 or other programmable processor 504. Once configured by such software, the hardware components become dedicated to executing the particular machine 500 (or particular components of the machine 500) being configured. The function is no longer general processor 504. It is no longer appreciated that the decision to mechanically implement a hardware component in a dedicated and permanently configured circuit, or in a temporarily configured circuit (e.g., configured by software) may be cost driven. And time considerations. Thus, the phrase "hardware component" (or "hardware-implemented component") should be understood to encompass a tangible entity, be it a physical construct, a permanent configuration (e.g., hardwired) or a temporary configuration (e.g., programmed). ) Operate or perform some of the operations described herein in a certain manner. Considering embodiments in which the hardware components are temporarily configured (e.g., programmed), each hardware component need not be configured or instantiated at any time. For example, where the hardware components include a general-purpose processor 504 configured by software to become a special-purpose processor, the general-purpose processor 504 may be configured as a different special-purpose processor (e.g., including different hardware components) at the following locations, respectively. At different times. Thus, software configures one or more particular processors 504 accordingly, e.g., to constitute particular hardware components at one instance in time and to constitute different hardware components at different instances in time. A hardware component may provide information to, or receive information from, other hardware components. Accordingly, the described hardware components may be considered communicatively coupled. Where multiple hardware components are present at the same time, communication may be achieved through signaling between or among two or more hardware components (e.g., through appropriate circuitry and bus 502). In embodiments in which multiple hardware components are configured or instantiated at different times, communication between such hardware components may be achieved, for example, by storing and retrieving information in memory structures accessible to the multiple hardware components. For example, one hardware component may perform an operation and store the output of the operation in a storage device to which it is communicatively coupled. Another hardware component may then access the storage device at a later time to retrieve and process the stored output. The hardware components may also initiate communication with an input or output device and may operate on a resource (e.g., a collection of information). Various operations of the example methods described herein may be performed, at least in part, by one or more processors 504 that are temporarily configured (e.g., via software) or permanently configured to perform the relevant operations. Whether temporarily or permanently configured, such a processor 504 may constitute processor-implemented components that execute to perform one or more operations or functions described herein. As used herein, "processor-implemented component" refers to a hardware component that is implemented using one or more processors 504. Similarly, the methods described herein may be implemented at least in part by a processor, where one or more specific processors 504 are examples of hardware. . For example, at least some of the operations of a method may be performed by one or more processors 504 or processor-implemented components. Further, the one or more processors 504 may also operate to support performance of related operations in a "cloud computing" environment or as a "software as a service" (SaaS). For example, at least some of the operations may be performed by a set of computers (as an example of a machine 500 that includes the processor 504), where the operations may be accessed via a network 532 (e.g., the internet) and via one or more appropriate interfaces. (e.g., an API). Execution of certain operations may reside not only within a single machine 500, but may be deployed across multiple machines 500 and distributed among processors 504. In some example embodiments, the processor 504 or processor-implemented components may be located in a single geographic location (e.g., in a home environment, an office environment, or a server farm). In other example embodiments, processor 504 or a processor-implemented component may be distributed across multiple geographic locations.

In this context, a "processor" refers to a processor that operates on control signals (e.g., "commands," "operation codes," "machine code," etc.) and generates corresponding output signals, which are applied to operate the machine 500. Processor 504 may be, for example, a Central Processing Unit (CPU), a Reduced Instruction Set Computing (RISC) processor, a Complex Instruction Set Computing (CISC) processor, a Graphics Processing Unit (GPU), a Digital Signal Processor (DSP), an ASIC, a Radio Frequency Integrated Circuit (RFIC), or any combination thereof. The processor may further be a multi-core processor having two or more independent processors 504 (sometimes referred to as "cores") that may execute instructions 510 simultaneously.

What has been described above is merely an embodiment of the present disclosure; however, the scope of the present disclosure is not limited thereto. It should be understood by those skilled in the art that the present disclosure includes, but is not limited to, what is described in the figures and examples. Any modification without departing from the functional and structural principles of the present disclosure is intended to be included within the scope of the claims.
