1. Field
The present invention relates to billing clients for products and services.
2. Background Art
For business transactions ranging in complexity from buying an item in a supermarket to buying a large property, different methods of billing a client have been developed. Some methods require the client to allocate funds to purchase the product before the product is received. Other methods require the provider to assume a substantial risk that the client will not pay for the product after receiving it. Although the methods of billing are typically chosen to be optimal for a particular type of transaction, the chosen billing methods often become inconvenient to client and/or the provider. Such billing methods typically remain static over the course of all transactions between the consumer and provider, and thus do not adapt to changing conditions between the consumer and provider.
Thus, what is needed is a method of billing that can adapt to changing conditions between a client and provider.
In one embodiment, a computer-implemented method of providing advertising to a client includes establishing a billing experience between a client and a provider, providing advertising opportunities to the client on at least one of a continual basis and a periodic basis, evaluating a credit risk associated with the client at least one of periodically and upon occurrence of an event, and modifying the billing experience automatically based on the credit risk associated with the client.
In another embodiment, a computer-implemented method of providing advertising to a client is provided. The method includes establishing a billing experience between a client and a provider, an account being subject to the billing experience having a credit line, evaluating a credit risk associated with the client at least one of periodically or upon occurrence of an event, modifying the billing experience based on the credit risk associated with the client, the billing experience being changed to one of the following billing experiences: a prepay billing experience, a partial prepay partial postpay billing experience, a threshold billing experience, or an end-of-team billing experience, providing advertising opportunities to the client on at least one of a continual basis or periodic basis, based on at least one of funds in the account, the credit line of the account, or the credit risk associated with the client, and billing the client for the advertising opportunities in a manner determined by the modified billing experience.
In yet another embodiment a system for providing advertising opportunities from a provider to a client is provided. The system includes an advertisement database that stores an advertisement of the client, a risk evaluation server that calculates a credit risk associated with the client based on at least one of a performance of the product of the client, a transaction history between the client and the provider, or a credit performance of the client, a billing server that changes, based on the calculated credit risk, a billing experience between the provider and the client to one of the following billing experiences: a prepay billing experience, a partial prepay partial postpay billing experience, a threshold billing experience, or an end-of-term billing experience, the billing server further billing the client at a time determined by the billing experience, and an advertisement supply server that displays the advertisement of the client at a rate determined by at least one of the billing experience between the provider and the client or the credit risk associated with the client.
Further embodiments, features, and advantages of the invention, as well as the structure and operation of the various embodiments of the invention are described in detail below with reference to accompanying drawings.
Embodiments of the invention are described with reference to the accompanying drawings. In the drawings, like reference numbers may indicate identical or functionally similar elements. The drawing in which an element first appears is generally indicated by the left-most digit in the corresponding reference number.
While the present invention is described herein with reference to illustrative embodiments for particular applications, it should be understood that the invention is not limited thereto. Those skilled in the art with access to the teachings provided herein will recognize additional modifications, applications, and embodiments within the scope thereof and additional fields in which the invention would be of significant utility.
Embodiments described herein refer to transactions between a client and a provider. A client, as described herein, may be a business, consumer, or group of businesses and/or consumers. The provider provides products to the client. As would be apparent to those skilled in the relevant art(s), products are not limited to physical goods. Rather, products may also include services or a combination of goods and services. Moreover, the provider may also provide a flow or stream of products. For example, the client may be a retailer and the provider may be an Internet advertisement server. In such an embodiment, the advertisement server may post advertisements that promote the retailer on an ongoing (e.g., continual and/or periodic) basis. In another example, the client may be a retailer and the provider may be a radio or video advertisement server. In such an embodiment, the advertisement server may deliver advertisements based on an order of the retailer. Alternatively or additionally, the provider may provide items that the retailer sells to customers. Often, the provider determines a suitable billing arrangement by which the provider bills for and eventually receives payment for the products it provides.
In describing different billing arrangements it is helpful to define deposit requirements and predictability of billing as measures of resource availability for the client and credit extended by the provider. Deposit requirements for different billing arrangements refer to funds that must be deposited with the provider before the desired products are provided to the client. Predictability of billing refers to how predictably (from the client's point of view) the provider bills the client.
As the deposit requirement of a billing arrangement increases, more and more of the client's resources are allocated to products before the benefit of the products is realized. Conversely, as the deposit requirement falls, more credit is extended by the provider and losses associated with a client who fails to pay increase.
As the predictability of billing increases, the client is benefited by being able to better budget for products provided. However, predictability of billing also results in greater risk for the provider because the client may run costs above what they can afford because there is no control in place to limit the client prior to being billed.
It is important to note, however, that the provider does have an interest in increasing resource availability for the client. First, resource availability may influence a client's decision in deciding between competing providers. Moreover, increased resource availability may also result in an increase in the client's demand for products thereby generating additional revenue for the provider. Thus, in deciding between billing arrangements, the provider must weigh the potential for increased revenue against the risk assumed.
In a pre-pay billing arrangement, the client is required to deposit a certain amount of funds before the provider begins to provide the desired products. As the provider delivers the desired products the amount of the client deposit is reduced. Once the deposit is fully exhausted (or reaches another predetermined minimum), the provider bills the client or notifies the client that the client needs to make a payment. The provider does not start providing the desired products again until the client deposit returns to a predetermined level.
As shown in
Also as shown in
In a credit threshold or post-pay billing arrangement, the provider bills the client once the account balance of the client (i.e., the amount owed by the client to the provider) reaches or nears (within a predetermined range) a credit line. This credit line may stay constant or change over time.
As the account balance of the client rises, account balance 210 is reached at time T1. Since credit line 202 is set at account balance 210, the client is billed at this point. After providing payment for the account balance at time T1, the client again begins to develop an account balance with the provider. At time T2, credit line 202 is increased to account balance 212, allowing the client to accrue a balance larger than account balance 210 which it was billed for at T1. At time T3, credit line 202 is reduced to account balance 214. Since the account balance of the client at time T3 is greater than balance 214, the client is billed at time T3.
Credit line 202 is unpredictable from the point of view the client, both in terms of the times at which credit line 202 will transition and of the account balance to which credit line 202 will transition. Similar to the pre-pay billing arrangement, then, the client does not know when a payment will be required from the provider. In contrast to the pre-pay billing arrangement, however, the client does not have funds allocated to products before the provider provides the desired products. Thus, the post-pay billing arrangement allows the client greater resource availability since funds are taken from the client after the desired products are provided.
From the provider's perspective, the post-pay billing arrangement results in an increased credit risk extended to the client over the pre-pay billing arrangement. By granting the client the ability to receive products before paying for them, the provider assumes a greater risk that the client will not pay for the products provided. However, the provider limits its risk by changing the credit line in accordance with a risk associated with a client, so that a suspected risky client will not be given the opportunity to run up a balance higher than the client can afford to pay.
A pre-pay billing arrangement may be viewed as a special case of the credit threshold or post-pay billing arrangement in which the credit line is set to zero. In such a pre-pay billing arrangement, to ensure that the amount deposited with the provider will cover the demand for products, the provider often places a portion of the deposited funds in a budget used to account for an unexpectedly large demand. If the budget is not exhausted, the budget may be carried over to the next deposit by the client. In alternate pre-pay embodiments, the provider may instead extend the client a limited credit in the case of an unexpectedly large demand.
In an end-of-term billing arrangement, the provider extends the client a line of credit and bills the client at predictable times. For example, the provider may extend the client a line of credit in which products are provided for a predictable time period (e.g., a month) and bill the client at the end of the time period.
The end-of-term billing arrangement provides a greater degree of resource availability for the client. The end-of-term billing arrangement does not require the client to allocate funds to before products are delivered and the times at which the provider will bill the client are completely predictable.
However, in the end-of-term billing arrangement the provider extends a relatively high amount of credit. Further, since the provider provides products before receiving payment from the client, the client may not know the exact balance of the account or how much the client will be asked to pay at the end of the billing term.
Thus, the pre-pay, post-pay, and end-of-term are billing arrangements that involve different amounts of credit extended to the client, and thus different amounts of risk assumed by the provider. In the pre-pay billing arrangement, the provider extends little or no credit to the client. In the post-pay billing arrangement, the provider extends a limited amount of credit to the client and may change that limit unpredictably over time. In the end-of-team billing arrangement, the provider potentially extends the client an unlimited amount of credit and bills the client at the end of predictable time periods.
In conventional transactions with a client, a provider often decides to use one of the three different billing arrangements described above and keeps that arrangement throughout all transactions with the client. In embodiments described herein, however, billing parameters are updated as conditions change.
A billing experience includes various billing parameters that affect the interaction between a client and a provider. Billing parameters include, for example and without limitation, the credit line extended to the client, the frequency of billing, the cost of goods sold, and an outstanding order limit (for example, for radio or video advertisements, as will be described further below). In an embodiment, billing parameters of a billing experience are updated based on a credit risk associated with a client.
A client, as described above, may be a group of consumers and/or businesses, as well as a single consumer or business. More specifically, the group of consumers and/or businesses is considered a client if its members have correlated risk. In other words, a risk associated with a member of the client may be indicative of a risk associated with other members of the client and of the client as a whole. In evaluating the risk associated with a multi-member client, then, the risk may be calculated based on observations of the client as a whole as well as each individual member. Thus, a single credit account may be established for the client, rather than individual accounts for each member. For example, a single contact may be responsible for payments made to the provider on behalf of multiple businesses. The multiple businesses are, in this scenario, grouped into a single client since risk of the contact for one of the businesses is indicative of risk of the contact for another of the businesses.
The risk associated with a client may be determined through the use of a conventional credit check. However, conducting credit checks on clients is often costly and not time efficient. This is especially an issue when clients interact with the provider over the Internet, as automated requesting of a credit check is not typically an option. Moreover, dynamically updating the risk associated with a client may result in additional delays and costs.
Alternatively, the risk associated with a client may be determined by the provider itself. Such a provider may make observations such as, for example and without limitation, a comparison between long term and short term demand for products, the presence of a guaranteed form of payment, the net present value of having a future supply of product to a client, and a payment history of the client. If there is a dramatic shift in recent demand for products, that may indicate that the client is unstable and therefore is a high risk. The presence of a guaranteed form of payment (i.e., a form of payment that may be accessed by the provider if the client delays payment or does not pay) decreases the risk associated with the client. Examples of forms of guaranteed payment include but are not limited to credit cards, bank accounts, and cash balances. The payment history of a client relates to how quickly the client pays bills from the provider. As the delay between bills and actual payment increases, the risk associated with the client also increases.
Risk evaluations may be automated such that the various criteria used to evaluate risk are observed periodically. Additionally or alternatively, risk evaluations may be event-based. For example, if the client releases a new item to be marketed to consumers, an event based risk evaluation may be executed. Generally, many different types of events may be used to trigger risk evaluation including but not limited to events relating to micro- and/or macro-economic events. For instance, events that trigger risk evaluation may be specific to the client (such as, release of an earning report, stock price change, bankruptcy event, etc.) specific to an industry of the client (such as, economic data indicating the performance of an industry), and/or specific to an economy generally (such as, stock exchange indices, government economic data, etc.). As would be apparent to persons skilled in the relevant art(s), risk evaluations can be partially or wholly implemented using software, firmware, hardware, or any combination thereof.
The results of risk evaluations may lead to updates in billing parameters in the billing experience between the provider and the client. For example, a cost of goods sold may be updated based on the results of a risk evaluation. In adjusting the cost of goods sold, a reliable (e.g., low risk) client is given access to products that are more expensive to produce, but are also more profitable to the provider. Such products are assumed to be desired by the client. The access to high cost goods may be limited to a high risk client, since it is less likely that they will pay for the goods, which would result in increased losses for the provider compared to lower cost goods. For example, in transactions with a reliable retailer, an advertisement server may allow for syndicated advertisements, video advertisements, and/or print advertisements that have a high cost of goods sold as compared to online advertisements having a low cost of goods sold, as would be appreciated by those skilled in the relevant art(s).
The credit line that the provider is willing to extend to a client may be increased or decreased based on the evaluated risk associated with the client. The frequency of ad hoc billing may be adjusted based on risk evaluations. For a high risk client, billing frequency may be increased to protect the provider from losses. Elements of the pre-pay, post-pay and end-of-term billing arrangements may be combined to a form a flexible billing experience, according to an embodiment of the present invention. The operation of a flexible billing experience is described with reference to
During time period 404, the billing experience of the retailer exhibits a pre-pay behavior generally similar to the pre-pay billing arrangement as described with reference to
Thus, in time period 406, the billing experience of the retailer exhibits a partial pre-pay partial post-pay behavior. As such, the retailer may be billed once the account balance reaches zero, but may also be allowed to accrue a positive account balance. As shown in
Alternatively, even if the retailer is not specifically billed at time T1, the negative balance may result from an ad hoc payment made by the retailer that is greater than the account balance. Such a payment may be made before the account balance reaches the credit line. Such a payment provides flexibility to the retailer as to when and how much the retailer pays, as a negative balance effectively extends the length of time (if all other parameters stay equal) until a next payment is due. Although not specifically illustrated in
At the end of period 406, the advertisement server decides to offer an increased amount of credit to the retailer. Thus, in time period 408, the billing experience exhibits a post-pay or credit threshold billing behavior. The retailer is billed every time the account balance reaches credit line 402. Moreover, credit line 402 increases throughout time period 406, indicating that the advertisement server is changing the billing parameters by extending an increasing amount of credit to the retailer. Although
At the start of time period 410, the billing experience of the retailer exhibits an end-of-term behavior. As shown by
The embodiment of
As would be appreciated by those skilled in the relevant art(s), periodic risk evaluations may also be used to gradually decrease credit associated with a client that demonstrates high risk.
Returning to
On June 1, the retailer is billed in the predictable manner for an account balance 502. Between June 1 and July 1, the account balance of the retailer again reaches credit line 516. However, in this case, a guaranteed form of payment is not available when the advertisement server attempts an ad hoc billing and the account balance of the retailer is not reduced. In response, the advertisement server may throttle the advertisements of the retailer. In throttling the advertisements of the retailer, the advertisement server decreases the rate at which the advertisements of the retailer are served. As shown in
Throttling and/or stopping display of the advertisements in this manner allows the advertisement server to minimize any additional risk due to potential non-payment for additional advertisements. Throttling and/or stopping display also sends a message to the client that they have exceeded their credit line and incentivizes the client to pay the balance so that display of the advertisements is resumed.
In an embodiment, the advertisements are radio and/or video advertisements rather than Internet advertisements. With radio and/or video advertisements, the client places an order (also referred to as a commitment) to run and pay for an advertisement. Once the order has been placed, the provider may not be able to throttle the actual running of the advertisement. The provider then accepts a risk, because the client cannot be billed until confirmation that the advertisements were run (e.g., via tear sheets) is received from the advertisement publisher. This delay can be significant. So, if the risk associated with the client begins to increase, the provider may throttle the orders available to the client rather than the actual display of the advertisements.
Once the risk associated with the client decreases, the throttle may be released, or the product supply may be reinitiated if stopped completely. The decrease in risk may occur when the client has met more restrictive requirements than were previously necessary. For example, the client may be required to provide an additional guaranteed form of payment. In another example, the client may be required to operate under a billing experience more restrictive than prior to the event where the credit risk of the client increased.
Thus, in the embodiment of
Conversely, if the advertisement server observes a relatively large number of billing cycles where the retailer's demand for advertisements has remained relatively constant and/or makes other observations that indicate a relatively low risk associated with the retailer, the advertisement server may increase the credit line, decrease or eliminate ad hoc bills, and/or reduce throttling of the retailer's advertisements.
Thus through the use of periodic or event-based assessments of the risk associated with a client, a billing experience can be updated in real time. In such a billing experience, the client is, then, effectively allowed to build credit with the provider. Moreover, when billing parameters are updated in favor of the client (i.e., increase in credit limit, decrease in the frequency of billing, etc.) the client may tend to spend more on the product. Therefore, the flexible billing experience allows the provider to choose those clients that will generate the most revenue for the provider as deserving of the advantageous billing parameters, thereby maximizing revenue from reliable clients. Also, by adjusting billing parameters, the provider can manage risk associated with less reliable clients.
Moreover, adjusting billing parameters may depend on the desires of the client. For example, even if risk evaluations indicate that a credit line may be increased, the client may decide that it does not have the necessary funds to budget for such an increase. In such a case, the provider may provision the credit line so that the credit line is increased no further than the limit specified by the client.
As would be appreciated by those skilled in the relevant art(s), each of the elements of system 600 may be implemented as a server or otherwise as hardware, software, firmware, or any combination thereof. Each element of system 600 may be coupled to other elements of system 600 through the use of a communication network such as the Internet. For example, client risk evaluation and rules engine 602 is shown conceptually to include client module 604, credit module 606, and billing experience module 608 in a single unit. However, each of client risk evaluation and rules engine 602, client module 604, credit module 606, and billing experience module 608 may be implemented a separate server and coupled together through the Internet or other communication network. Additionally or alternatively, other elements such as accounts database 610 and billing engine 612 may be implemented as separate servers and coupled together through the Internet or other communication network.
As shown in
Method 700 begins with step 702. In step 702, a billing experience is initiated between a retailer and an advertisement server. In an embodiment, initiating the billing experience may involve establishing an account for the retailer and/or providing a product to the retailer. For example, in system 600 of
In step 704, billing parameters are set for the retailer. As described above, billing parameters may include a credit line. In an embodiment, the credit line may be initially set to zero so that no credit is extended to the retailer. For example, in system 600 of
In step 706, a credit risk associated with the retailer is evaluated. The credit risk may be evaluated periodically and/or based on upon occurrence of an event. In an embodiment, the risk associated with the retailer is based on at least one of a review of a demand for products by the retailer, spending by the retailer with the advertisement server, and a payment history of the retailer to the advertisement server. The occurrence of an event may include, for example and without limitation, monetization, an order from a retailer, non-payment or partial payment of an invoice after a given time period, and exceeding a given fraction of the credit line by the total credit risk. For example, in system 600 of
In step 708, it is determined whether one or more billing parameters should be changed. In an embodiment, one or more billing parameters may be changed in response to the credit risk evaluated in step 706. As described above, billing parameters may include the credit line, the frequency of billing, and the cost of goods sold. In an embodiment, the credit line that the advertisement server is willing to extend to the retailer may be increased in response to a decreased risk associated with the retailer. Alternatively, the credit line that the advertisement server is willing to extend to the retailer may be decreased in response to an increased risk associated with the retailer. In system 600 of
In step 710, the billing experience itself may be changed. In an embodiment, changing the billing experience may include changing the billing experience from an experience having a lower credit line to a billing experience having a higher credit line. For example, changing the billing experience may include changing from a pre-pay billing experience to a partial pre-pay partial post-pay billing experience, changing a credit threshold billing experience to an end-of-term billing experience, increasing a length of a term for an end-of-term billing experience, or increasing a credit line for a credit threshold billing experience.
Alternatively, changing the billing experience may include changing the billing experience from an experience having a higher credit line to a billing experience having a lower credit line. For example, changing the billing experience may include changing from a partial pre-pay partial post-pay billing experience to a pre-pay billing experience or changing an end-of-term billing experience to a credit threshold billing experience.
In a further embodiment, billing experience module 608 may change the billing experience between the retailer and the Internet advertisement server from one that exhibits behavior similar to a pre-pay billing arrangement, and further to an experience that exhibits partial pre-pay partial post pay behavior, as described with reference to
As shown by
In optional step 712, an intermediate action is taken. The intermediate action may include, for example and without limitation, executing an ad hoc bill or allowing the retailer to make an ad hoc payment. The retailer may be provided with an indication of the retailer's risk level and/or credit line. In an embodiment where the client includes multiple entities, such as multiple retailers, the indication may be provided to the client in such a manner that the risk correlations used to group the entities into one client is at least partially hidden from any one of the entities. Moreover, an intermediate action may involve notifying the retailer of possible changes in the billing parameters. The retailer may be notified that the advertisement server is willing to increase the credit line of the retailer and be advised that the retailer is eligible for a higher credit line. Alternatively, the retailer may be notified that the advertisement server has decreased the credit line. The credit line may be decreased below a credit line requested by the retailer. If the credit line is decreased below an account balance of the retailer, the intermediate action may further include a collection from a guaranteed form of payment to bring the account balance below the new credit line.
A retailer may also be offered a guarantee mechanism or guaranteed form of payment that will increase the credit line that the advertisement server is willing to extend to the retailer. A guaranteed form of payment may include, but is not limited to, a credit card held in reserve or a cash balance. In such an embodiment, a billing parameter (e.g., the credit line) may be changed and the general behavior of the billing experience may be retained. In a further embodiment, the guarantee mechanism may be acted on by charging a credit card held in reserve, depleting a cash balance, or initiating action on a guarantor, for example. If the guaranteed form of payment fails, the provider can react negatively and may apply this information in future credit risk calculations.
In an embodiment, the guarantee mechanism may also be removed by the provider as the risk associated with the retailer decreases. In another embodiment, the intermediate action may be a reaction taken by the provider when the client removes the guaranteed form of payment. When this happens, the provider may react by, for example and without limitation, decreasing the credit line or acting on a still-available guaranteed form of payment.
An intermediate action in step 712 may include taking action based on a change in evaluated credit risk of the retailer. For example, the rate at which the advertisement server provides products to the retailer may be reduced (i.e., throttled) or completely stopped in response to changes in the evaluated credit risk of the retailer.
In system 600 of
In step 714, payment is received from the retailer in accordance with the billing parameters and/or experience. For example, billing engine 612 may bill the retailer in accordance with the billing parameters. Billing engine 612 also may update accounts database 610 to indicate when the retailer has paid the bill.
Aspects of the present invention, for example method 700 or system 600 or any part(s) or function(s) thereof may be implemented using hardware, software, firmware, or a combination thereof and may be implemented in one or more computer systems or other processing systems. However, the manipulations performed by the present invention were often referred to in terms, such as adding or comparing, which are commonly associated with mental operations performed by a human operator. No such capability of a human operator is necessary, or desirable in most cases, in any of the operations described herein which form part of the present invention. Rather, the operations are machine operations. Useful machines for performing the operation of the present invention include general purpose digital computers or similar devices.
In fact, in one embodiment, the invention is directed toward one or more computer systems capable of carrying out the functionality described herein. An example of a computer system 800 is shown in
The computer system 800 includes one or more processors, such as processor 804. The processor 804 is connected to a communication infrastructure 806 (e.g., a communications bus, cross over bar, or network). Various software embodiments are described in terms of this exemplary computer system. After reading this description, it will become apparent to a person skilled in the relevant art(s) how to implement the invention using other computer systems and/or architectures.
Computer system 800 can include a display interface 802 that forwards graphics, text, and other data from the communication infrastructure 806 (or from a frame buffer not shown) for display on the display unit 830.
Computer system 800 also includes a main memory 808, preferably random access memory (RAM), and may also include a secondary memory 810. The secondary memory 810 may include, for example, a hard disk drive 812 and/or a removable storage drive 814, representing a floppy disk drive, a magnetic tape drive, an optical disk drive, etc. The removable storage drive 814 reads from and/or writes to a removable storage unit 818 in a well known manner. Removable storage unit 818 represents a floppy disk, magnetic tape, optical disk, etc. which is read by and written to by removable storage drive 814. As will be appreciated, the removable storage unit 818 includes a computer usable storage medium having stored therein computer software and/or data.
In alternative embodiments, secondary memory 810 may include other similar devices for allowing computer programs or other instructions to be loaded into computer system 800. Such devices may include, for example, a removable storage unit 822 and an interface 820. Examples of such may include a program cartridge and cartridge interface (such as that found in video game devices), a removable memory chip (such as an erasable programmable read only memory (EPROM), or programmable read only memory (PROM)) and associated socket, and other removable storage units 822 and interfaces 820, which allow software and data to be transferred from the removable storage unit 822 to computer system 800.
Computer system 800 may also include a communications interface 824. Communications interface 824 allows software and data to be transferred between computer system 800 and external devices. Examples of communications interface 824 may include a modem, a network interface (such as an Ethernet card), a communications port, a Personal Computer Memory Card International Association (PCMCIA) slot and card, etc. Software and data transferred via communications interface 824 are in the form of signals 828 which may be electronic, electromagnetic, optical or other signals capable of being received by communications interface 824. These signals 828 are provided to communications interface 824 via a communications path (e.g., channel) 826. This channel 826 carries signals 828 and may be implemented using wire or cable, fiber optics, a telephone line, a cellular link, a radio frequency (RF) link and other communications channels.
In this document, the terms “computer program medium” and “computer usable medium” are used to generally refer to media such as removable storage drive 814 and a hard disk installed in hard disk drive 812. These computer program products provide software to computer system 800. The invention is directed to such computer program products.
Computer programs (also referred to as computer control logic) are stored in main memory 808 and/or secondary memory 810. Computer programs may also be received via communications interface 824. Such computer programs, when executed, enable the computer system 800 to perform the features of the present invention, as discussed herein. In particular, the computer programs, when executed, enable the processor 804 to perform the features of the present invention. Accordingly, such computer programs represent controllers of the computer system 800.
In an embodiment where the invention is implemented using software, the software may be stored in a computer program product and loaded into computer system 800 using removable storage drive 814, hard drive 812 or communications interface 824. The control logic (software), when executed by the processor 804, causes the processor 804 to perform the functions of the invention as described herein.
In another embodiment, the invention is implemented primarily in hardware using, for example, hardware components such as application specific integrated circuits (ASICs). Implementation of the hardware state machine so as to perform the functions described herein will be apparent to persons skilled in the relevant art(s).
In yet another embodiment, the invention is implemented using a combination of both hardware and software.
Exemplary embodiments of the present invention have been presented. The invention is not limited to these examples. These examples are presented herein for purposes of illustration, and not limitation. Alternatives (including equivalents, extensions, variations, deviations, etc., of those described herein) will be apparent to persons skilled in the relevant art(s) based on the teachings contained herein. Such alternatives fall within the scope and spirit of the invention. Thus, the present invention should not be limited by any of the above described exemplary embodiments, but should be defined only in accordance with the following claims and their equivalents.
In addition, it should be understood that the figures illustrated in the attachments, which highlight the functionality and advantages of the present invention, are presented for example purposes only. The architecture of the present invention is sufficiently flexible and configurable, such that it may be utilized (and navigated) in ways other than that shown in the accompanying figures.
Further, the purpose of the foregoing Abstract is to enable the U.S. Patent and Trademark Office and the public generally, and especially the scientists, engineers and practitioners in the art who are not familiar with patent or legal terms or phraseology, to determine quickly from a cursory inspection the nature and essence of the technical disclosure of the application.
