METHOD AND SYSTEM FOR FACILITATING DATA TRANSFER BETWEEN A FIRST PLATFORM AND A SECOND PLATFORM
FIELD OF DISCLOSURE
[0001] Embodiments of the present disclosure relate generally to the field of wireless communication systems. More particularly, embodiment of the present disclosure relates to a method and system for facilitating data transfer between at least a first platform and at least a second platform.
BACKGROUND
[0002] The following description of the related art is intended to provide background information pertaining to the field of the disclosure. This section may include certain aspects of the art that may be related to various features of the present disclosure. However, it should be appreciated that this section is used only to enhance the understanding of the reader with respect to the present disclosure, and not as admissions of the prior art.
[0003] With the evolution and development of communication technology, the number of people communicating with each other, and the rate at which information is communicated between people is increasing day by day. Also, with this development, more and more people are getting familiar with digital platforms to communicate with each other and are switching to use digital platforms to exchange voice calls over the existing traditional platform for making voice calls. Thus, the demands of people regarding features that these digital platforms provide is also increasing.
[0004] In the existing systems, people can interact with each other on a common digital platform by installing and using an application related to the digital platform. For this purpose, two users need to install a software application of the digital

platform on their user devices, such as smartphone, tablet etc. Then, the users can place calls using voice over internet protocol feature on their devices.
[0005] However, the existing systems do not provide a functionality of communicating with users on different platforms, meaning that, a user cannot place a call using one digital platform to another user on another digital platform. This is also because every digital platform uses a defined set of ports to connect devices. Two or more devices are able to connect with each other by using the same set of ports that the digital platform has the access to. However, with the evolving needs of the users, it is needed that the users can place calls to other users from one digital platform to another digital platform to exchange data using the voice over internet protocol (VoIP).
[0006] Thus, there exists an imperative need in the art to provide a method and system for data transfer through voice over internet protocol (VoIP) between different digital platforms, which the present disclosure aims to address.

[0057] FIG. 2 illustrates an exemplary block diagram of a computing device [200] upon which the features of the present disclosure may be implemented in
20 accordance with exemplary implementation of the present disclosure. In an
implementation, the computing device [200] may also implement a method for facilitating data transfer between at least a first platform and at least a second platform utilising the system. In another implementation, the computing device [200] itself implements the method for facilitating data transfer between at least a
25 first platform and at least a second platform using one or more units configured
within the computing device [200], wherein said one or more units are capable of implementing the features as disclosed in the present disclosure.
[0058] The computing device [200] may include a bus [202] or other
30 communication mechanism for communicating information, and a hardware
processor [204] coupled with bus [202] for processing information. The hardware
15

processor [204] may be, for example, a general-purpose microprocessor. The
computing device [200] may also include a main memory [206], such as a random-
access memory (RAM), or other dynamic storage device, coupled to the bus [202]
for storing information and instructions to be executed by the processor [204]. The
5 main memory [206] also may be used for storing temporary variables or other
intermediate information during execution of the instructions to be executed by the
processor [204]. Such instructions, when stored in non-transitory storage media
accessible to the processor [204], render the computing device [200] into a special-
purpose machine that is customized to perform the operations specified in the
10 instructions. The computing device [200] further includes a read only memory
(ROM) [208] or other static storage device coupled to the bus [202] for storing static information and instructions for the processor [204].
[0059] A storage device [210], such as a magnetic disk, optical disk, or solid-state
15 drive is provided and coupled to the bus [202] for storing information and
instructions. The computing device [200] may be coupled via the bus [202] to a
display [212], such as a cathode ray tube (CRT), Liquid crystal Display (LCD),
Light Emitting Diode (LED) display, Organic LED (OLED) display, etc. for
displaying information to a computer user. An input device [214], including
20 alphanumeric and other keys, touch screen input means, etc. may be coupled to the
bus [202] for communicating information and command selections to the processor
[204]. Another type of user input device may be a cursor controller [216], such as a
mouse, a trackball, or cursor direction keys, for communicating direction
information and command selections to the processor [204], and for controlling
25 cursor movement on the display [212]. This input device typically has two degrees
of freedom in two axes, a first axis (e.g., x) and a second axis (e.g., y), that allow
the device to specify positions in a plane.
[0060] The computing device [200] may implement the techniques described
30 herein using customized hard-wired logic, one or more ASICs or FPGAs, firmware
and/or program logic which in combination with the computing device [200] causes
16

or programs the computing device [200] to be a special-purpose machine.
According to one implementation, the techniques herein are performed by the
computing device [200] in response to the processor [204] executing one or more
sequences of one or more instructions contained in the main memory [206]. Such
5 instructions may be read into the main memory [206] from another storage medium,
such as the storage device [210]. Execution of the sequences of instructions
contained in the main memory [206] causes the processor [204] to perform the
process steps described herein. In alternative implementations of the present
disclosure, hard-wired circuitry may be used in place of or in combination with
10 software instructions.
[0061] The computing device [200] also may include a communication interface [218] coupled to the bus [202]. The communication interface [218] provides a two-way data communication coupling to a network link [220] that is connected to a
15 local network [222]. For example, the communication interface [218] may be an
integrated services digital network (ISDN) card, cable modem, satellite modem, or a modem to provide a data communication connection to a corresponding type of telephone line. As another example, the communication interface [218] may be a local area network (LAN) card to provide a data communication connection to a
20 compatible LAN. Wireless links may also be implemented. In any such
implementation, the communication interface [218] sends and receives electrical, electromagnetic or optical signals that carry digital data streams representing various types of information.
25 [0062] The computing device [200] can send messages and receive data, including
program code, through the network(s), the network link [220] and the communication interface [218]. In the Internet example, a server [230] might transmit a requested code for an application program through the Internet [228], the ISP [226], the local network [222], the host [224] and the communication interface
30 [218]. The received code may be executed by the processor [204] as it is received,
17

and/or stored in the storage device [210], or other non-volatile storage for later execution.
[0063] Referring to FIG. 3, an exemplary block diagram of a system [300] for
5 facilitating data transfer between at least a first platform and at least a second
platform is shown, in accordance with the exemplary implementations of the present disclosure.
[0064] In one example, the system [300] may be in communication with other
10 network entities/components known to a person skilled in the art. Such network
entities/components have not been depicted in FIG. 3 and have not been explained here for the sake of brevity.
[0065] In another example, the system [300] may be implemented as or within a
15 centralized server in the network. In such cases, the system [300] may be in
communication with all the network entities/components, such as all User Equipment, in the network.
[0066] Further, FIG. 4 illustrates an exemplary flow diagram for facilitating data
20 transfer between at least a first platform and at least a second platform in accordance
with exemplary implementations of the present disclosure.
[0067] It may be noted that the FIG. 3 and FIG. 4 have been explained simultaneously and may be read in conjunction with each other.

Also, all of the components/ units of the system [300] are assumed to be connected to each other unless otherwise indicated below. As shown in FIG. 3, all
30 units shown within the system [300] should also be assumed to be connected to
each other. Also, in FIG. 3 only a few units are shown, however, the system [300]
18

may comprise multiple such units or the system [300] may comprise any such
numbers of said units, as required to implement the features of the present
disclosure. Further, in an implementation, the system [300] may be present in a user
device/ user equipment [102] to implement the features of the present disclosure.
5 The system [300] may be a part of the user device [102]/ or may be independent of
but in communication with the user device [102] (may also referred herein as a UE). In another implementation, the system [300] may reside in a server or a network entity. In yet another implementation, the system [300] may reside partly in the server/ network entity and partly in the user device. 10
[0069] The system [300] is configured for facilitating data transfer between at least a first platform and at least a second platform, with the help of the interconnection between the components/units of the system [300].
15 [0070] In one example, a plurality of User Equipment (UEs) may be registered in
a network. Each of the UE may be operated by and associated with their respective user. Examples of such UE may include, but are not limited to, a smartphone, a tablet, a portable computer, a handheld device, a wearable device, or any other device capable of communicating over a network.

[0071] In an example, at least two User Equipment, say First UE [402] and a Second UE [404] may intend to communicate with each other. Such communication may involve a data transfer between the first UE [402] and the second UE [404].
25 [0072] It may be noted that, the present description has been explained with respect
to communication and facilitation of data transfer between the first UE [402] and the second UE [404]. Further, for facilitating such data transfer, in the context of the present invention, the first UE [402] may initiate the process and establish the connection with the second UE [404]. It may be noted that the same is done only
30 for the sake of example and clarity, and should not be construed to limit the scope
of the present subject matter in any manner. The approaches of the present subject
19

matter may be implemented for implementing communication and facilitating data
transfer between any number of UEs in the network, and any UE initiating such
process. For example, the second UE [404] may also initiate the process. In such
cases, the system [300] may be a part of the second UE [404]. All such and other
5 examples would lie within the scope of the present subject matter.
[0073] In an example, a first platform may be provided on the first UE [402]. Such platform may allow the first UE to connect, over the network, with the system [300], and initiate and establish a connection with the second UE [404]. In a similar
10 manner, a second platform may be provided on the second UE [404], which may be
again allow the second UE [404] to connect with the system [300] and establish a connection with the first UE [402]. In one example, the first platform and the second platform may be a first application and a second application installed on the first UE and the second UE respectively.
15
[0074] In one example, the second platform may be similar to the first platform. In another example, the first platform may be different from the second platform.
[0075] As described previously, for implementing the communication between the
20 first UE and the second UE, data transfer therebetween may need to be facilitated.
The data transfer, between the first UE and the second UE, may be done through the respective platforms, i.e., the first platform and the second platform.
[0076] In an example, the data may be in a format that may be supported by at least
25 one of the first UE and the second UE. In another example, in cases where the data
may not be supported by at least one of the first UE and the second UE, the present disclosure encompasses converting the data in a pre-defined format, such that the data may be compatible for the transfer therebetween, and thereafter, facilitating the data transfer. 30
20

[0077] In another example, the data transfer between the first platform and the second platform may be based on Voice over Internet Protocol (VoIP). In such cases, the first UE and the second UE may be compatible and optimized for establishing a connection for VoIP-based communication. 5
[0078] The Voice over Internet Protocol (VoIP) is a technology that enables voice communication over the internet rather than through traditional phone lines. It converts voice signals into digital data packets, which are then transmitted over an IP network, such as the internet.
10
[0079] In another example, prior to initiating the communication and facilitating the data transfer between the first platform and the second platform, the first UE, associated with the first platform, and the second UE, associated with the second platform, may need to register with the network. As described previously, in one
15 example, the system [300] may be implemented as a centralized server. In such
cases, the first UE and the second UE may need to register themselves at the network through the centralized server.
[0080] In one example, the respective platforms provided on the respective UEs
20 may allow the UEs to register themselves on the centralized server. The respective
platforms may serve as an intermediary for facilitating data transfer and managing communication data.
[0081] In one example, such registration may be a one-time procedure that stores
25 the details of the first UE and the second UE in a database for future use. These
details of the user may include, but not limited to, a contact number of the user,
email id of the user, location of the user etc. In another example, every time the first
UE and the second UE attempts to implement a communication and facilitate data
transfer, registration may be required. It may be again noted that all such
30 aforementioned registration techniques are only exemplary, and should not be
construed to limit the scope of the present subject matter in any manner. Any other
21

manner of registration of the UE may also lie within the scope of the present subject matter.
[0082] Continuing further, in operation, for facilitating the data transfer between
5 the first platform and the second platform, the first platform, which may be provided
on at least the first User Equipment (UE), initiates the communication process by sending a request to the system [300]. This has been depicted by Step [406] in FIG. 4.
10 [0083] This request is a digital message or signal that asks for a connection to be
established with the second platform, provided on at least the second User Equipment (UE). The request typically includes all necessary details required to set up the connection. For example, the request may include the contact details of the second UE, to which the connection is to be established. Along with that, the request
15 may also include certain details of the first UE, such as, but not limited to, first
platform details, contact details of first UE, profile data of the user operating the first UE, and encryption details.
[0084] The transceiver unit [302] of the system [300] may receive, from at least the
20 first platform, the request for establishing the connection with at least the second
platform.
[0085] Continuing further, on receiving said request, the determination unit [304]
may determine a validity of at least the first UE, associated with the first platform,
25 and the at least second UE, associated with the second platform. Such determination
may be made by the determination unit [304] based on registration of the first UE and the second UE. This has been depicted by Step [408] in FIG. 4.
[0086] In an implementation of the present disclosure, the determination unit [304]
30 is to assess whether the first UE [402] and the second UE [404] are registered and
valid participants in the data transfer. The term ‘validity’ refers to whether the UEs
22

are authorized, authenticated, and properly registered with the network. Further, the determination of the validity may also involve verifying that the devices have been authenticated by a network, are recognized by the system, and are eligible to engage in the data transfer. 5
[0087] In one example, the details of all the UEs, that may be registered in the network, may be stored in one or more repositories. In such cases, the determination unit [304] may check the validity of the first UE and the second UE against such repositories, by checking whether an identifier corresponding to the first UE and
10 the second UE is present in the repository or not. In another example, the request,
sent by the first platform, may include a set of parameters corresponding to the first UE and the second UE. In such cases, the determination unit [304] may check the parameters, of each of the first UE and the second UE, for determining the validity. However, it may be noted that all such methods of determination of the validity of
15 the first UE and the second UE are only exemplary, and any other techniques known
to a person skilled in the art may also be used. All such examples would lie within the scope of the present subject matter.
[0088] In one example, if the validation is unsuccessful, i.e., the first UE and the
20 second UE are not valid, referred to as ‘negative validity’, the request for
establishing the connection of the first platform with the second platform may be
rejected. In such cases, the determination unit [304] may again attempt to determine
the validity. This has been depicted by Step [410] in FIG. 4. In one example, the
determination unit [304] may keep determining the validity, till the time the
25 validation is successful. In another example the determination unit [304] may keep
determining the validity for a pre-defined time period. In yet another example, the determination unit [304] may keep determining the validity for a pre-define number of times.
23

[0089] In another example, the first UE, through the first platform, may be provided with a notification and a negative acknowledgement that the first platform is not valid to establish the connection with the second platform.
5 [0090] In another example, If the validation is successful, i.e., the first UE and the
second UE are valid, referred to as ‘positive validity’, the process of establishing the connection of the first platform with the second platform may proceed forward. This has been depicted by Step [412] in FIG. 4.
10 [0091] In an implementation of the present disclosure, the term ‘positive validity
refers to the successful validation of the first and second User Equipment (UE) by the determination unit [304]. The ‘positive validity’ means that both UEs have been confirmed as authorized and eligible for communication.
15 [0092] Once the processing unit [306] receives confirmation of positive validity
from the determination unit [304], the process of establishment of the connection of the first platform with the second platform may be initiated.
[0093] In another example, the first platform may also be notified and provided
20 with an acknowledgement that the first platform is valid for establishing the
connection with the second platform.
[0094] Continuing further, in another example, once the validity of the first UE and the second UE is determined, the determination unit [304] may check a database
25 [414] for details of second UE, against the details received in the request from the
first platform, to establish the connection of the first platform with the second platform. Examples of such details of the second UE that may be checked from the database [414] may include, but are not limited to, IP address of the second UE and other identifying data.
30
24

[0095] In yet another example, for establishing the connection between at least the
first platform and at least the second platform, the determination unit [304] may
further determine an availability of at least the second platform. It may be noted
that step of determination of the availability of the second platform is optional, and
5 may not be necessarily performed by the determination unit [304]. The connection
may be established between the first platform and the second platform based on the validity of the first UE and the second UE, without further determining the validity of the second platform.
10 [0096] Continuing further, in one example, once the validity of the first UE and the
second UE are determined, the determination unit [304] may then be tasked with verifying whether the second platform is available before the connection is established. The availability means that the second platform is ready for communication. This involves checking, for example, if the second platform is
15 powered on, connected to the network, not engaged in another session, ready to
receive or send data, etc.
[0097] In an example, the availability of the second platform may be checked by sending a network query to see if it responds, indicating it is online and reachable.
20 The determination unit [304] may also verify the platform's status through
registration and authentication checks, confirming it is active and ready for communication. Additionally, health checks may be performed to confirm that the second platform is functioning correctly. These methods collectively confirm that the second platform is ready to accept a connection before proceeding with
25 establishing the link.
[0098] Once the determination unit [304] confirms that the second platform is
available and confirmed to be ready and capable of engaging in the data transfer or
communication, referred to as determination of a ‘positive validity’, the
30 determination unit [304] may initiate the process of establishment of the connection
of the first platform with the second platform.
25

[0099] In another example, upon determination of the positive validity, the
transceiver unit [302] may also transmit a notification to the second platform
indicative of the transmitted request. For example, the second UE, through the
5 second platform, may receive a notification that the first platform, associated with
the first UE, wants to establish a connection, allowing the connection to be
established if User B accepts. This notification serves as an acknowledgment or
indication that the request has been sent and is awaiting a response. This process
ensures a secure and efficient setup for the communication session between the two
10 users.
[0100] Considering an example, say, a video call is initiated from the first UE (through the first platform) to the second UE (through the second platform). The system [300] first checks if the second UE is available, whether it is turned on,
15 connected to the internet, and ready to receive calls. Once the second UE is
confirmed as available, the first UE sends a connection request to the second UE to initiate the call. At the same time, the first UE sends a notification to the second UE, indicating that a call request has been sent. The second UE then processes this request and prepares to establish the video call if it accepts the request.
20
[0101] In yet example, for establishing the connection between at least the first platform and at least the second platform, after determination of the positive validity of the first UE and the second UE, and determination of positive availability of the second platform, the transceiver unit [302] may transmit the request (received from
25 at least the first platform) to a session border controller [418]. This has been
depicted by Step [416] in FIG. 4. As described previously, the request is a signal or message that initiates the connection process, informing the second platform that the first platform wants to establish a communication.
26

[0102] As would be further understood, a Session Border Controller (SBC) is a network component designed to protect and manage SIP-based VoIP communications. The SBC ensures the call is routed correctly and securely.
5 [0103] After receiving the request from the system [300], the Session Border
Controller [418] forwards it to one or more network devices [422], such as a router. This has been depicted by Step [420] in FIG. 4. The router [422] then directs the request, via a network [424], to its final destination. i.e., the second platform. This has been depicted by Step [426] in FIG. 4. 10
[0104] Thereafter, the connection between the first platform and the second platform may be established to allow the data transfer therebetween.
[0105] Referring to FIG. 5, an exemplary method flow diagram [500] for
15 facilitating data transfer between at least a first platform and at least a second
platform in accordance with exemplary implementations of the present disclosure
is shown. In an implementation the method [500] is performed by the system [300].
Further, in an implementation, the system [300] may be present in a server device
to implement the features of the present disclosure. Also, as shown in FIG. 5, the
20 method [500] starts at step [502].
[0106] At step [504], the method comprises, receiving, by a transceiver unit [302], from at least a first platform, a request for establishing a connection with at least a second platform.
25
[0107] In one example, a plurality of User Equipment (UEs) may be registered in a network. Each of the UE may be operated by and associated with their respective user. In an example, at least two User Equipment, say First UE [402] and a Second UE [404] may intend to communicate with each other. Such communication may
30 involve a data transfer between the first UE [402] and the second UE [404].
27

[0108] In an example, a first platform may be provided on the first UE [402]. Such
platform may allow the first UE to connect, over the network, with the system [300],
and initiate and establish a connection with the second UE [404]. In a similar
manner, a second platform may be provided on the second UE [404], which may be
5 again allow the second UE [404] to connect with the system [300] and establish a
connection with the first UE [402]. In one example, the second platform may be similar to the first platform. In another example, the first platform may be different from the second platform.
10 [0109] In operation, the transceiver unit [302] of the system [300] may receive,
from at least the first platform, the request for establishing the connection with at least the second platform.
[0110] At step [506], the method [500] comprises, determining, by a determination
15 unit [304], a validity of at least a first UE associated with the first platform and at
least a second UE associated with the second platform, based on registration of the first UE and the second UE.
[0111] Continuing further, on receiving said request, the determination unit [304]
20 may determine a validity of at least the first UE, associated with the first platform,
and the at least second UE, associated with the second platform. Such determination may be made by the determination unit [304] based on registration of the first UE and the second UE.
25 [0112] In an implementation of the present disclosure, the determination unit [304]
is to assess whether the first UE [402] and the second UE [404] are registered and valid participants in the data transfer. The term ‘validity’ refers to whether the UEs are authorized, authenticated, and properly registered with the network.
28

[0113] In another example, If the validation is successful, i.e., the first UE and the second UE are valid, referred to as ‘positive validity’, the process of establishing the connection of the first platform with the second platform may proceed forward.
5 [0114] In an implementation of the present disclosure, the term ‘positive validity
refers to the successful validation of the first and second User Equipment (UE) by the determination unit [304]. The ‘positive validity’ means that both UEs have been confirmed as authorized and eligible for communication.
10 [0115] At step [508], the method [500] comprises, in response to determination of
a positive validity of at least the first UE and at least the second UE, establishing, by a processing unit [306], a connection between at least the first platform and at least the second platform to allow data transfer therebetween.
15 [0116] Once the processing unit [306] receives confirmation of positive validity
from the determination unit [304], the process of establishment of the connection of the first platform with the second platform may be initiated.
[0117] In another example, the first platform may also be notified and provided
20 with an acknowledgement that the first platform is valid for establishing the
connection with the second platform.
[0118] Continuing further, in another example, once the validity of the first UE and the second UE is determined, the determination unit [304] may check a database
25 [414] for details of second UE, against the details received in the request from the
first platform, to establish the connection of the first platform with the second platform. Examples of such details of the second UE that may be checked from the database [414] may include, but are not limited to, IP address of the second UE and other identifying data.
30
29

[0119] In yet another example, for establishing the connection between at least the first platform and at least the second platform, the determination unit [304] may further determine an availability of at least the second platform.
[0120] For example, once the validity of the first UE and the second UE are determined, the determination unit [304] may then be tasked with verifying whether the second platform is available before the connection is established. The availability means that the second platform is ready for communication. This involves checking, for example, if the second platform is powered on, connected to the network, not engaged in another session, ready to receive or send data, etc.
[0121] Once the determination unit [304] confirms that the second platform is available and confirmed to be ready and capable of engaging in the data transfer or communication, referred to as determination of a ‘positive validity’, the determination unit [304] may initiate the process of establishment of the connection of the first platform with the second platform.
[0122] Thereafter, the connection between the first platform and the second platform may be established to allow the data transfer therebetween.
[0123] Thereafter, the method terminates at step [510].
[0124] The present disclosure further discloses a first User Equipment (UE). The first UE may include a memory and a processor connected to the memory. The processor may be configured to transmit, by a first platform, a request to a system. The request is used by the system for establishing a connection and facilitating data transfer between at least the first platform at least a second platform. On receiving the request from the first platform, the system may be configured to determine a validity of at least a first UE associated with the first platform and at least a second UE associated with the second platform based on registration of the first UE and the second UE. The system may be further configured to, in response to

determination of a positive validity of at least the first UE and at least the second UE, establish a connection between at least the first platform and at least the second platform to allow data transfer therebetween.
[0125] The present disclosure further discloses a non-transitory computer readable storage medium storing instructions for facilitating data transfer between at least a first platform and at least a second platform. The instructions include executable code which, when executed by one or more units of a system, causes a transceiver unit [302] of the system to receive, from at least a first platform, a request for establishing a connection with at least a second platform. Further, the instructions include executable code which, when executed, causes a determination unit [304] to determine a validity of at least a first UE associated with the first platform and at least a second UE associated with the second platform based on registration of the first UE and the second UE. Further, the instructions include executable code which, when executed, causes a processing unit [306] to establish, in response to determination of a positive validity of at least the first UE and at least the second UE, a connection between at least the first platform and at least the second platform to allow data transfer therebetween.
[0126] As is evident from the above, the present disclosure provides a technically advanced solution for facilitating data transfer between at least a first platform and at least a second platform. The present solution serves as a unique intermediary platform that integrates multiple applications related to multiple digital platforms. Also, implementing the features of the present disclosure enables seamless voice data transfer using the VoIP protocol between different digital platforms. Further, implementing the features of the present disclosure allows users who are using different platforms for voice transmission to communicate without coming on same platforms, thus saving the infrastructure resources and costs.
[0127] While considerable emphasis has been placed herein on the disclosed implementations, it will be appreciated that many implementations can be made and

that many changes can be made to the implementations without departing from the principles of the present disclosure. These and other changes in the implementations of the present disclosure will be apparent to those skilled in the art, whereby it is to be understood that the foregoing descriptive matter to be implemented is illustrative and non-limiting.
[0128] Further, in accordance with the present disclosure, it is to be acknowledged that the functionality described for the various components/units can be implemented interchangeably. While specific embodiments may disclose a particular functionality of these units for clarity, it is recognized that various configurations and combinations thereof are within the scope of the disclosure. The functionality of specific units as disclosed in the disclosure should not be construed as limiting the scope of the present disclosure. Consequently, alternative arrangements and substitutions of units, provided they achieve the intended functionality described herein, are considered to be encompassed within the scope of the present disclosure.
