[0003] For payment and other service fields, two-dimensional codes have been popularized, but in actual application, for some users or some scenarios, payment based on two-dimensional codes also requires relatively cumbersome operations. With the increasing number of user mobile terminals, especially smart phones, with near field communication (NFC) function, many smart phones support near field communication payment method, which helps to further improve the operation convenience compared with two-dimensional code payment.

[0053] The embodiments of the present specification provide a near field interaction service processing method, device, equipment and storage medium.

[0054] ​​In order for those skilled in the art to better understand the technical solutions in the specification, the technical solutions in the specification will be clearly and completely described below in combination with the drawings in the specification. Obviously, the described embodiments are only some of the embodiments of the present application, not all. Based on the specification embodiments, all other embodiments obtained by those of ordinary skill in the art without creative labor should fall within the scope of protection of the present application.

[0055] The scheme of the present application at least involves a service machine and a user mobile terminal. The user mobile terminal mainly includes a smart phone, a smart wearable device, and the smart wearable device, with a smart watch as a typical one, and can also be some other devices such as a smart bracelet, a smart ring, etc. The scheme of the present application can be implemented especially for a user mobile terminal without a near field communication function or a near field communication function that is not turned on, so as to better reflect the advantages of the scheme.

[0056] Figure 1 A flowchart of a near distance interaction service processing method applied to a service machine is provided for one or more embodiments of the specification. The flowchart is described from the perspective of the service machine, and the execution subject of the flowchart includes the service machine. The execution subject on the software level can specifically include a designated service application or an operating system on the service machine. The designated service application includes, for example, a payment application or an instant messaging application, etc.

[0057] Taking a payment scenario as an example, the service machine can be a cash register device of a merchant, or an auxiliary cash register device additionally extended on the basis of the cash register device, such as a near field communication cash register machine deployed to extend the near field communication capability, etc.

[0058] In some other scenarios, the service machine can be a device for providing corresponding other services, such as a check-in device, an access control device, a game device, etc.

[0059] Figure 1 The flowchart in the specification includes the following steps:

[0060] S102: broadcast a first Bluetooth signal carrying device information of the service machine to the surrounding, so that a user mobile terminal close to the service machine sends a sound wave signal carrying user terminal information of the user mobile terminal and the device information of the service machine to the service machine in response to the first Bluetooth signal.

[0061] The device information mentioned in the present application can be directly carried in plaintext, or indirectly carried by encryption for the purpose of targeted access by specific objects for security considerations. The device information is preferably identification information that can better distinguish the device from other devices, especially devices of the same type, such as a device ID or a physical address, etc. The user terminal information of the user mobile terminal can be the device information of the user mobile terminal itself, or the identification of the application end on the user mobile terminal related to the present scheme or the user account logged on the application end.

[0062] The first Bluetooth signal is a signal broadcast through Bluetooth communication. Since it is different from the second Bluetooth signal in at least the timing of transmission (the content carried and other aspects can also be different), in order to avoid confusion, it is also intuitively distinguished by the formal name.

[0063] In order to save resources and improve the pertinence to the user, the broadcast of the first Bluetooth signal can be triggered by an operation related to the current user. For example, a cashier clicks the "payment" button on the cash register for the current user; for example, the user clicks the "start checkout" button on the self-service cash register; for example, the device at the checkout counter detects that a user is approaching the checkout counter; etc.

[0064] For a user mobile terminal that wants to use a service business, the device information of the service machine can be obtained from the first Bluetooth signal, so as to further confirm the correct service machine through close-range interaction in the next step.

[0065] The service machine can be a device with near field communication function, such as a device with near field communication function that supports the scheme of the present application through software upgrade based on the existing near field communication function device, becoming the service machine mentioned in the present application. In this case, the user is more likely to recognize the service machine, and is more likely to understand that the service machine supports close-range interaction such as near field communication, so that the user can naturally adopt close-range interaction such as approaching or "touching", and even naturally think that he is performing near field communication interaction.

[0066] If the user mobile terminal has and opens the near field communication function, it can perform near field communication with the service machine, and trigger the service business corresponding to the service machine based on the near field communication. Otherwise, it can automatically interact with the service machine based on sound waves in response to the first Bluetooth signal, so that the user does not need to change the near field communication interaction operation habit, and the present application mainly focuses on this case.

[0067] In one or more embodiments of the present specification, the user mobile terminal as mentioned in the present application can support the generation of the sound wave signal required by the present application through a pre-upgrade of software, without the need for hardware improvements. Due to the control of energy level, transmission angle, etc., the generated and transmitted sound wave signal needs to be received more reliably in a short distance, so the user needs to place the user mobile terminal close to the service device within a short distance of tens of centimeters or even a few centimeters.

[0068] The sound wave signal carries the user terminal information of the user mobile terminal and the device information of the service device obtained from the first Bluetooth signal, so as to be verified by the service device. Assuming that the first Bluetooth signal is generated and broadcast based on a certain service business to be performed next (such as a payment business triggered by the cashier clicking the "payment" button for the current user), the business description information (such as order information or payment amount) for performing the service business can also be carried in the first Bluetooth signal, so as to make the user mobile terminal more clear about the meaning of the first Bluetooth signal and more reliably confirm the service business and confirm whether it is the current service target of the service device, which helps to prevent confusion of the service business.

[0069] S104: verifying according to the received sound wave signal.

[0070] In one or more embodiments of the present specification, when the sound wave signal is received, it can be verified whether it is a valid signal, such as detecting the synchronization header of the sound wave signal; in the case of detecting the synchronization header, judging whether the energy of the sound wave signal exceeds the set threshold; if so, it can be determined as a valid signal; otherwise, it can be considered as an interference signal in the environment and can be ignored. Of course, this is an exemplary valid signal determination method, and other different determination strategies can be used as needed, such as successfully received sound wave signals can also be defaulted as valid sound wave signals, etc.

[0071] For the received valid sound wave signal, the information carried in the sound wave signal can be further analyzed and verified, such as verifying whether the current service business to be performed is indeed for the device or user corresponding to the user terminal information according to the analyzed user terminal information of the user mobile terminal. More verification can also be performed as needed to ensure that the service business is more secure and reliable.

[0072] S106: if the verification is passed, a second Bluetooth signal carrying the user terminal information of the user mobile terminal is sent, so that the user mobile terminal triggers the execution of the service business corresponding to the service device in response to the second Bluetooth signal.

[0073] In one or more embodiments of the present specification, the second Bluetooth signal can also be broadcasted, so that there is no need to establish a point-to-point Bluetooth connection with the user mobile terminal, which is more efficient and saves resources. The user terminal information carried by the second Bluetooth signal is obtained from the received sound wave signal, so that the user mobile terminal is confirmed through the second Bluetooth signal, and the service business to be performed next is indeed for the user mobile terminal, and the user mobile terminal can trigger the service business execution with confidence.

[0074] The first Bluetooth signal and the second Bluetooth signal can respectively carry business description information for performing a service business, and the user mobile terminal can temporarily store the business description information obtained from the first Bluetooth signal before, and after receiving the second Bluetooth signal, it can verify whether the business description information carried by the first Bluetooth signal and the second Bluetooth signal is consistent. If it is consistent, it can be determined that it is the correct service target and that the service business to be performed is the one it expects, and it can trigger the corresponding service business of the service appliance to execute according to the business description information this time. If it is not consistent, it means that it may be confused with other users' service businesses, and it can temporarily not trigger the service business execution, but re-verify to avoid errors.

[0075] For the user mobile terminal, in order to improve security and prevent interaction with the wrong service appliance, it can also actively perform security detection based on one or more sensors it has for the current scene.

[0076] For example, the user mobile terminal actively performs a security water level verification before triggering the corresponding service business of the service appliance to execute, and determines through the security water level verification that the service appliance belongs to a predetermined target device (for example, assuming that the present scheme is improved based on an existing near field communication device, the target device can be a target near field communication device). If it belongs to the predetermined target device, it can trigger the service business execution, otherwise it can be considered not safe enough and the user needs to re-verify.

[0077] The security water level verification includes at least one of the following: automatically starting the camera of the user mobile terminal, collecting images of the service appliance, and verifying the service appliance according to the collected images to visually determine whether the target device is in front of it; magnetic field strength detection to verify whether the magnetic field change brought by the service appliance conforms to the magnetic field capability of the near field communication device, such as the magnetic field capability of a general near field communication coil; inertia data detection to verify whether the motion state of the user mobile terminal conforms to the near field communication interaction characteristics, such as whether it is forward and then touches; and the like.

[0078] The specific execution of the service can be designed according to needs. Generally, at least two of the three parties—the user's mobile terminal, the service device, and the corresponding remote server (e.g., a payment server)—can interact to complete the service execution. For example, the user's mobile terminal can interact with the remote server to execute the service. After execution, the remote server can notify the service device of the result. In this way, after the service device sends a second Bluetooth signal, it can automatically terminate the service upon receiving the result without interacting with the user's mobile terminal.

[0079] pass Figure 1 This method allows users to interact with the service device using standard near-field communication (NFC) regardless of whether their mobile device (e.g., a smartwatch or smartphone) supports NFC or whether NFC is disabled. Users simply bring their mobile device close to the device to trigger the service. Users can seamlessly follow their NFC interaction habits and perceive the transaction as being completed via NFC. Technically, the solution uses Bluetooth combined with sound waves. The service device actively broadcasts a Bluetooth signal to guide the user's mobile device to approach and verify the connection via sound waves. The service device then reconfirms the connection with the user's mobile device via another Bluetooth signal, reliably triggering the service. This solution effectively addresses situations where NFC is not supported or is disabled, thus improving payment convenience, service device utilization, and service reliability.

[0080] based on Figure 1 In addition to the method described herein, this specification also provides some specific implementation schemes and extension schemes of this method, which will be further explained below.

[0081] To more reliably confirm the user's intentions, one or more embodiments of this specification also provide an acoustic signal verification scheme, see [link to relevant documentation]. Figure 2 , Figure 2 This is a flowchart illustrating the scheme.

[0082] S202: When the user mobile terminal approaches the service equipment, the user mobile terminal is detected to be close to it, and the moment when the user mobile terminal approaches to a set close range is taken as the first moment.

[0083] Proximity detection can be performed using methods such as TOF sensors or motion detection cameras, enabling the detection of whether a user's mobile terminal is approaching the service equipment before the user's mobile terminal enters the near-field communication range or the communication range of the acoustic signal of this application.

[0084] The user mobile terminal that is approached can be the user mobile terminal that intends to use the service device, but it is only possible and temporarily difficult to confirm. For the user who really intends, not only will the user mobile terminal be approached, but there is a high probability that the user mobile terminal will be further approached continuously and smoothly, enter the communication range of the sound wave signal of the present application, and then send the sound wave signal.

[0085] S204: receiving the sound wave signal sent by the user mobile terminal, which carries the user terminal information of the user mobile terminal and the device information of the service device.

[0086] S206: determining the time when the sound wave signal is received as the second time.

[0087] S208: judging whether the time difference between the second time and the first time does not exceed a set threshold.

[0088] Suppose it is the same user mobile terminal that is approached and then sends the sound wave signal, as mentioned above, since there is a high probability of continuous and smooth approaching action, and the first Bluetooth signal can be received by the user mobile terminal in advance, the generation of the sound wave signal will not be delayed, and after continuous and smooth approaching, there is also a high probability that the sound wave signal can be sent immediately, therefore, the time difference between the second time and the first time (the first time will be earlier) will be small. According to the actual situation, by setting a suitable threshold (for example, 1 second or several seconds, etc.), if the time difference does not exceed the set threshold, it is considered that the time difference is small enough to verify that the user mobile terminal for approaching detection and the user mobile terminal for sending the sound wave signal are the same user mobile terminal.

[0089] On the contrary, if the time difference exceeds the set threshold, it is possible that the user mobile terminal for approaching detection and the user mobile terminal for sending the sound wave signal are not the same user mobile terminal. Therefore, since the service business this time can not be for the user mobile terminal for sending the sound wave signal, it can be considered to be determined as not passing the verification.

[0090] S210: determining that the verification passes in the case where the judgment result is yes.

[0091] In the flow of Figure 2 , at least the judgment result is yes, which can determine that the verification passes.

[0092] In addition to the verification in step S208, some other aspects of verification are mentioned above, if the required verification passes respectively, it can be considered that the verification this time passes.

[0093] By Figure 2The scheme can more accurately anchor the same target user in a round of process, and then more reliably and accurately serve the target user, so as to avoid confusion with other users who actually have no intention.

[0094] The time difference scheme above is exemplary, and other schemes can also be used instead, for example, verification can be based on echo confirmation, in which case the user mobile terminal and the service device can perform bidirectional acoustic wave communication, and if the user mobile terminal receives and analyzes the acoustic wave signal well, this scheme can be considered.

[0095] For example, the service device can first send an acoustic wave signal carrying the device information of the service device to the user mobile terminal close to the service device; the user mobile terminal can verify whether the device information carried by the first Bluetooth signal and the acoustic wave signal corresponds to the same service device, and in the case of verification, the acoustic wave signal is sent to the service device to perform echo, a short time limit can be set for the echo, and if the echo is not timely, an exception or failure can be triggered; if the user mobile terminal does not receive the acoustic wave signal sent by the service device, or the verification finds that it does not correspond to the same service device, the user terminal can not perform echo. In this way, it can effectively help the user who really has the intention to interact with the correct service device and avoid false interaction.

[0096] Further, the application also provides an adaptive selection scheme for the above two verification schemes, which helps to automatically select a scheme that may be more suitable for the current situation according to the specific situation. Specifically, when performing proximity detection, the user mobile terminal is also detected for motion stability, and if the motion stability detection does not pass, it is considered that the user mobile terminal is not stable enough due to large shaking, which may affect the reception and analysis of the acoustic wave signal. Therefore, the bidirectional acoustic wave communication scheme can not be used this time, and the service device can be determined not to send the acoustic wave signal to the user mobile terminal this time, and the time difference based verification scheme can be used instead, such as continuing to trigger the execution of the judgment that whether the time difference between the second time and the first time is not more than the set threshold. Conversely, if the motion stability detection passes, the bidirectional acoustic wave communication scheme can be considered for verification.

[0097] In one or more embodiments of the present specification, the user's preference features are also considered based on the acoustic wave signal, and based on such ideas, a cooperation processing scheme of acoustic wave signal and Bluetooth signal is provided, which is described in detail in the following. Figure 3 , Figure 3 The flowchart of the scheme is shown in the following.

[0098] Figure 3 The flowchart in the above includes the following steps:

[0099] S302: The user mobile terminal generates the sound wave signal by re-modulating the music being played by the user mobile terminal through Bluetooth.

[0100] In order to better protect the privacy of the user, the process can be performed on the premise that the user has given the corresponding authorization.

[0101] The music being played is directly audible to the human ear, while the sound wave signal generated by re-modulation (such as modulation to high frequency, and of course, other information can be additionally encoded therein) is a signal that cannot be directly heard by the human ear or a sound that can be heard but cannot directly understand its meaning.

[0102] During the re-modulation process, the characteristics of the music can be selectively collected, and irrelevant data can be discarded, such as the general tune of the music, individual characteristic obvious singing, etc.

[0103] If the user terminal is not playing music through Bluetooth, the sound wave signal carrying the required information can be randomly generated or generated according to other default strategies.

[0104] It should be noted that the sound wave signal can be generated by re-modulating the source signal (the audio signal at a certain processing stage before being played out from the Bluetooth earphone) of the music being played by the user mobile terminal through the Bluetooth earphone, so that the source signal can be collected, and signal interference can be reduced and reliability can be improved.

[0105] In one or more embodiments of the present specification, a first Bluetooth signal carrying a near field communication control indication signal is broadcasted to the surroundings to trigger the user mobile terminal to detect whether music is currently being played through Bluetooth or a call is currently being made through Bluetooth; through the near field communication control indication signal, it is indicated that the near field communication function is closed when the user mobile terminal is currently playing music through Bluetooth, and the near field communication function is opened when the user mobile terminal is currently making a call through Bluetooth, so as to trigger the corresponding service business of the service device through near field communication.

[0106] In this way, it is helpful to avoid affecting the Bluetooth call, and it is also possible to adaptively select the near field communication mode without the additional benefit of the preferred feature, which takes into account the processing efficiency and the additional possible benefits.

[0107] Similarly, such detailed distinction can also not be made, such as, when it is detected that the user mobile terminal is not currently playing music through Bluetooth, the near field communication mode is preferred, and of course, if the user mobile terminal itself does not have the near field communication function, it can not respond to the corresponding control.

[0108] S304: The user mobile terminal, in response to the first Bluetooth signal, sends an acoustic signal carrying user terminal information of the user mobile terminal and device information of the service device to the service device.

[0109] To facilitate the transmission of sound wave signals, the user's mobile terminal's external speaker module can be adaptively activated only when transmission is needed, so as not to affect the user's continued music playback via Bluetooth.

[0110] S306: The service device demodulates and identifies the sound wave signal to obtain descriptive information about the music.

[0111] Since the music is currently playing on the user's mobile device, it can reflect the user's preferences to a certain extent, and these preferences are timely. Therefore, it has good practical value. This application considers using it immediately to try to proactively provide positive feedback to the user.

[0112] The descriptive information about music can be keywords inherent in the music itself, or preference tags summarized based on the music.

[0113] S308: The service device generates and sends a second Bluetooth signal based on the description information of the music.

[0114] The second Bluetooth signal additionally carries some preference features indicated by the description information, which may be the description information itself or features further refined from it.

[0115] S310: The user mobile terminal, in response to the second Bluetooth signal, opens a page that matches the description information of the music, to assist in the execution of the service.

[0116] This page can display products or services that cater to user preferences. Users can select content that interests them and then perform services related to that content, such as adding products they are interested in to their cart and paying for them at the same time.

[0117] pass Figure 3 The proposed solution can make fuller use of sound wave signals to achieve additional valuable applications without increasing the interaction burden.

[0118] Figure 1 This description is from the perspective of service equipment. Based on the same idea, one or more embodiments of this specification also provide another near-field interaction service processing method, described from the perspective of the user's mobile terminal. Figure 4 This is a flowchart illustrating this alternative method.

[0119] Figure 4The flow in the method comprises the following steps:

[0120] S402: receiving a first Bluetooth signal broadcasted by a service device, the first Bluetooth signal carrying device information of the service device.

[0121] S404: in response to the first Bluetooth signal, sending a sound wave signal carrying user terminal information of the user mobile terminal and device information of the service device to the service device when the user mobile terminal is close to the service device, the device information of the service device being obtained from the first Bluetooth signal.

[0122] S406: receiving a second Bluetooth signal carrying user terminal information of the user mobile terminal sent by the service device after the service device verifies the sound wave signal.

[0123] S408: in response to the second Bluetooth signal, triggering the service device to execute corresponding service business.

[0124] For details, refer to the foregoing description.

[0125] According to the foregoing description, for the purpose of understanding, intuitively, the one or more embodiments of the present specification provide a method for implementing a solution in an application scenario, Figure 1 a solution, and a system for implementing Figure 5 the solution, see Figure 5 , Figure 6 . Figure 5 a flowchart of the solution, Figure 6 a structural diagram of the system.

[0126] In the application scenario of Figure 5 , the user mobile terminal is a smart watch, specifically, for example, a smart watch that does not support near field communication function, the service device is a near field communication cash register device, the smart watch is installed with a payment application for payment, referred to as a watch payment application in the figure, and the server is a server of the watch payment application. The user wants to make payment through the watch payment application, and the near field communication cash register device correspondingly provides cash register service business.

[0127] Figure 5 The flow in the method comprises the following steps:

[0128] The near field communication cash register device initiates payment, the user opens the watch payment application on the smart watch, and after entering the watch payment application, automatically starts Bluetooth scanning, and optionally, can also automatically start the camera of the smart watch (if any) and perform image recognition. The watch payment application can also actively send a Bluetooth entry broadcast, indicating that it is ready to pay;

[0129] The near field communication cash register device sends a Bluetooth sound wave pairing broadcast (as the first Bluetooth signal described above) in response to the Bluetooth entry broadcast, the Bluetooth sound wave pairing broadcast carrying device information (denoted as idN) of the near field communication cash register device and description information (denoted as BLE token) of the current payment;

[0130] The smart watch receives the Bluetooth sound wave pairing broadcast, and the user can place the smart watch close to the device for payment. In this process, the near field communication cash register device can detect the approach of the smart watch based on the TOF sensor, and can record the time when the smart watch approaches to a range close enough, denoted as the TOF time (as the first time described above). In this process, the watch payment application can also perform image recognition or behavior judgment processing to achieve security level detection, and the detection can also be delayed for execution.

[0131] The watch payment application sends a sound wave signal to the near field communication cash register device, the sound wave signal carrying device information (denoted as idW) of the smart watch and idN obtained from the Bluetooth sound wave pairing broadcast;

[0132] The near field communication cash register device compares the TOF time with the time when the sound wave signal is received. If the time difference is small enough (for example, within 1 second), it is passed, and the process of synchronization detection, signal strength detection, data verification, etc. is continued. idN is extracted from the sound wave signal for verification, and idW is extracted.

[0133] The near field communication cash register device further sends a Bluetooth payment broadcast (as the second Bluetooth signal described above) carrying BLE token and idW;

[0134] The smart watch receives the Bluetooth payment broadcast and can verify the broadcast related data such as BLE token, idW, etc. to determine whether it is the correct near field communication cash register device and whether it is this payment. After all the verifications are passed, the payment can be continued, for example, according to the BLE token to interact with the server, and the BLE token is replaced with more specific payment information to realize payment.

[0135] In addition, if the smart watch has and opens the near field communication function, it can also adaptively decide when to use the near field communication mode and when to use the Bluetooth signal combined with the sound wave signal scheme of the present application. For example, the communication effective distance of the sound wave signal can be controlled to be shorter than the near field communication effective distance, so as to try to use the near field communication first. If there is an abnormal or inefficient situation, the Bluetooth signal combined with the sound wave signal scheme is used as an auxiliary and timely intervention to help the service business to be reliably executed.

[0136] In combination with the process description in Figure 5 , the process described in Figure 6The above-mentioned exemplary system structure division and function brief can be understood by the following simple description.

[0137] In Figure 6 The Bluetooth receiving module and the Bluetooth sending module are mainly related to the broadcast of the Bluetooth signal, wherein the data carried can be processed and provided by the master control module; the audio module, the encoding module and the signal processing module are mainly related to the interaction of the sound wave signal; the payment module is mainly related to the management and promotion of the payment state; the TOF module is related to the proximity detection based on TOF; the multi-modal verification module is related to one or more aspects of additional verification actively performed by the smart watch; in addition, the data processing module is related to data comparison and other operations.

[0138] Through Figure 5 and Figure 6 , it is helpful to solve the problem that the user mobile terminal without near field communication function fails to interact with the near field communication, and based on the cooperation of the Bluetooth signal and the sound wave signal, efficient and reliable one-to-one pairing between the user mobile terminal and the service machine is realized, which can avoid wrong payment, the user operation is simple, the experience is good, and the use rate and service reliability of the near field communication service machine can be improved.

[0198] In the 1990s, it was possible to distinguish whether an improvement in a technology was a hardware improvement (e.g., an improvement in the circuit structure of a diode, transistor, switch, etc.) or a software improvement (an improvement in a method flow). However, as technology has advanced, many improvements in method flows today can be considered as direct improvements in hardware circuit structures. Designers almost always obtain the corresponding hardware circuit structure by programming the improved method flow into a hardware circuit. Therefore, it cannot be said that an improvement in a method flow cannot be implemented using a hardware entity module. For example, a programmable logic device (PLD) (e.g., a field programmable gate array (FPGA)) is an integrated circuit whose logic function is determined by user programming of the device. A designer programs a digital system "integrated" on a PLD by himself / herself, without having to ask a chip manufacturer to design and manufacture a special integrated circuit chip. Moreover, instead of manually manufacturing an integrated circuit chip, this programming is now mostly implemented using "logic compiler" software, which is similar to a software compiler used when developing a program, and the original code before compilation must also be written in a specific programming language, which is called a hardware description language (HDL), and there are many types of HDL, such as ABEL (Advanced Boolean Expression Language), AHDL (Altera Hardware Description Language), Confluence, CUPL (Cornell University Programming Language), HDCal, JHDL (Java Hardware Description Language), Lava, Lola, MyHDL, PALASM, RHDL (Ruby Hardware Description Language), etc., and the most commonly used are VHDL (Very-High-Speed Integrated Circuit Hardware Description Language) and Verilog. Those skilled in the art should also be aware that it is only necessary to logically program a method flow using the above-mentioned hardware description languages and program it into an integrated circuit to easily obtain a hardware circuit that implements the logical method flow.

[0199] The controller can be implemented in any suitable way, for example, the controller can take the form of a microprocessor or processor and a computer readable medium storing computer readable program code, such as software or firmware, executable by the (micro)processor, logic gates, switches, an application specific integrated circuit (ASIC), a programmable logic controller and an embedded microcontroller, examples of which include but are not limited to the following microcontrollers: ARC 625D, Atmel AT91SAM, Microchip PIC18F26K20 and Silicone Labs C8051F320, the memory controller can also be implemented as part of the control logic of the memory. Those skilled in the art will also know that, in addition to implementing the controller purely in computer readable program code, it is possible to implement the same functionality with logic gates, switches, application specific integrated circuits, programmable logic controllers and embedded microcontrollers by logically programming the method steps. The controller can thus be considered a hardware component, and the means included therein for implementing the various functions can be considered structures within the hardware component. Alternatively, or even additionally, the means for implementing the various functions can be considered both software modules implementing the method and structures within the hardware component.
