The present application relates generally to electronic commerce and, in one specific example, to a pricing and listing configuration recommendation engine.
Ecommerce transactions, such as online sales and auctions, have now surpassed traditional consumer transactions in total revenue. Typically, ecommerce transactions begin with a seller creating a listing, which includes an offer to sell or auction the item. The listing is created using one or more configuration parameters. For example, in the case of an online auction, a seller may be able to specify reserve price, starting bid, time of auction end, number of photos attached to listing, whether free shipping is offered, promotional placement, and other configuration parameters.
Some embodiments are illustrated by way of example and not limitation in the figures of the accompanying drawings in which:
Example methods and systems for text translation in ecommerce services are provided. It will be evident, however, to one skilled in the art that the present inventive subject matter may be practiced without these specific details.
According to various exemplary embodiments, historical usage and sales information regarding ecommerce transactions is used to make recommendations to sellers as to one or more configuration settings. In this way, sellers can improve their changes of obtaining high sales volumes and/or maximizing sales prices.
An Application Program Interface (API) server 114 and a web server 116 are coupled to, and provide programmatic and web interfaces respectively to, one or more application servers 118. The application servers 118 host one or more marketplace applications 120 and payment applications 122. The application servers 118 are, in turn, shown to be coupled to one or more database servers 124 that facilitate access to one or more databases 126.
The marketplace applications 120 may provide a number of marketplace functions and services to users who access the networked system 102. The payment applications 122 may likewise provide a number of payment services and functions to users. The payment applications 122 may allow users to accumulate value (e.g., in a commercial currency, such as the U.S. dollar, or a proprietary currency, such as “points”) in accounts, and then later to redeem the accumulated value for products (e.g., goods or services) that are made available via the marketplace applications 120. While the marketplace and payment applications 120 and 122 are shown in
Further, while the system 100 shown in
The web client 106 accesses the various marketplace and payment applications 120 and 122 via the web interface supported by the web server 116. Similarly, the programmatic client 108 accesses the various services and functions provided by the marketplace and payment applications 120 and 122 via the programmatic interface provided by the API server 114. The programmatic client 108 may, for example, be a seller application (e.g., the TurboLister application developed by eBay Inc., of San Jose, California) to enable sellers to author and manage listings on the networked system 102 in an off-line manner, and to perform batch-mode communications between the programmatic client 108 and the networked system 102.
The networked system 102 may provide a number of publishing, listing, and price-setting mechanisms whereby a seller may list (or publish information concerning) goods or services for sale, a buyer can express interest in or indicate a desire to purchase such goods or services, and a price can be set for a transaction pertaining to the goods or services. To this end, the marketplace and payment applications 120 and 122 are shown to include at least one publication application 200 and one or more auction applications 202, which support auction-format listing and price setting mechanisms (e.g., English, Dutch, Vickrey, Chinese, Double, Reverse auctions, etc.). The various auction applications 202 may also provide a number of features in support of such auction-format listings, such as a reserve price feature whereby a seller may specify a reserve price in connection with a listing and a proxy-bidding feature whereby a bidder may invoke automated proxy bidding.
A number of fixed-price applications 204 support fixed-price listing formats (e.g., the traditional classified advertisement-type listing or a catalogue listing) and buyout-type listings. Specifically, buyout-type listings (e.g., including the Buy-It-Now (BIN) technology developed by eBay Inc., of San Jose, California) may be offered in conjunction with auction-format listings, and allow a buyer to purchase goods or services, which are also being offered for sale via an auction, for a fixed-price that is typically higher than the starting price of the auction.
Store applications 206 allow a seller to group listings within a “virtual” store, which may be branded and otherwise personalized by and for the seller. Such a virtual store may also offer promotions, incentives, and features that are specific and personalized to a relevant seller.
Reputation applications 208 allow users who transact, utilizing the networked system 102, to establish, build, and maintain reputations, which may be made available and published to potential trading partners. Consider that where, for example, the networked system 102 supports person-to-person trading, users may otherwise have no history or other reference information whereby the trustworthiness and credibility of potential trading partners may be assessed. The reputation applications 208 allow a user (for example, through feedback provided by other transaction partners) to establish a reputation within the networked system 102 over time. Other potential trading partners may then reference such a reputation for the purposes of assessing credibility and trustworthiness.
Personalization applications 210 allow users of the networked system 102 to personalize various aspects of their interactions with the networked system 102. For example a user may, utilizing an appropriate personalization application 210, create a personalized reference page at which information regarding transactions to which the user is (or has been) a party may be viewed. Further, a personalization application 210 may enable a user to personalize listings and other aspects of their interactions with the networked system 102 and other parties.
The networked system 102 may support a number of marketplaces that are customized, for example, for specific geographic regions. A version of the networked system 102 may be customized for the United Kingdom, whereas another version of the networked system 102 may be customized for the United States. Each of these versions may operate as an independent marketplace or may be customized (or internationalized) presentations of a common underlying marketplace. The networked system 102 may accordingly include a number of internationalization applications 212 that customize information (and/or the presentation of information by the networked system 102) according to predetermined criteria (e.g., geographic, demographic or marketplace criteria). For example, the internationalization applications 212 may be used to support the customization of information for a number of regional websites that are operated by the networked system 102 and that are accessible via respective web servers 116.
Navigation of the networked system 102 may be facilitated by one or more navigation applications 214. For example, a search application (as an example of a navigation application 214) may enable key word searches of listings published via the networked system 102. A browse application may allow users to browse various category, catalogue, or inventory data structures according to which listings may be classified within the networked system 102. Various other navigation applications 214 may be provided to supplement the search and browsing applications.
In order to make listings available via the networked system 102 as visually informing and attractive as possible, the applications 120 and 122 may include one or more imaging applications 216, which users may utilize to upload images for inclusion within listings. An imaging application 216 also operates to incorporate images within viewed listings. The imaging applications 216 may also support one or more promotional features, such as image galleries that are presented to potential buyers. For example, sellers may pay an additional fee to have an image included within a gallery of images for promoted items.
Listing creation applications 218 allow sellers to conveniently author listings pertaining to goods or services that they wish to transact via the networked system 102, and listing management applications 220 allow sellers to manage such listings. Specifically, where a particular seller has authored and/or published a large number of listings, the management of such listings may present a challenge. The listing management applications 220 provide a number of features (e.g., auto-relisting, inventory level monitors, etc.) to assist the seller in managing such listings. One or more post-listing management applications 222 also assist sellers with a number of activities that typically occur post-listing. For example, upon completion of an auction facilitated by one or more auction applications 202, a seller may wish to leave feedback regarding a particular buyer. To this end, a post-listing management application 222 may provide an interface to one or more reputation applications 208, so as to allow the seller conveniently to provide feedback regarding multiple buyers to the reputation applications 208.
Dispute resolution applications 224 provide mechanisms whereby disputes arising between transacting parties may be resolved. For example, the dispute resolution applications 224 may provide guided procedures whereby the parties are guided through a number of steps in an attempt to settle a dispute. In the event that the dispute cannot be settled via the guided procedures, the dispute may be escalated to a third party mediator or arbitrator.
A number of fraud prevention applications 226 implement fraud detection and prevention mechanisms to reduce the occurrence of fraud within the networked system 102.
Messaging applications 228 are responsible for the generation and delivery of messages to users of the networked system 102 (such as, for example, messages advising users regarding the status of listings at the networked system 102 (e.g., providing “outbid” notices to bidders during an auction process or to provide promotional and merchandising information to users)). Respective messaging applications 228 may utilize any one of a number of message delivery networks and platforms to deliver messages to users. For example, messaging applications 228 may deliver electronic mail (e-mail), instant message (IM), Short Message Service (SMS), text, facsimile, or voice (e.g., Voice over IP (VoIP)) messages via the wired (e.g., the Internet), plain old telephone service (POTS), or wireless (e.g., mobile, cellular, WiFi, WiMAX) networks 104.
Merchandising applications 230 support various merchandising functions that are made available to sellers to enable sellers to increase sales via the networked system 102. The merchandising applications 230 also operate the various merchandising features that may be invoked by sellers, and may monitor and track the success of merchandising strategies employed by sellers.
The networked system 102 itself, or one or more parties that transact via the networked system 102, may operate loyalty programs that are supported by one or more loyalty/promotions applications 232. For example, a buyer may earn loyalty or promotion points for each transaction established and/or concluded with a particular seller, and be offered a reward for which accumulated loyalty points can be redeemed.
The bid database 302 may contain information about bids placed on auctions, including, for example, listing identification, customer identification, timestamp, and amount. The won auction database 304 may contain information about auctions that have been won, including, for example, customer identification, listing identification, seller identification, amount, and timestamp.
The seller database 306 may contain information about sellers, including, for example, seller identification, seller reputation, seller historical transactions, seller location, etc. The customer database 308 may contain information about customers, including, for example, customer identification, customer reputation, customer historical transactions, customer location, etc.
The listing details database 310 may contain details about particular listings, including, for example, seller identification, listing identification, listing price, listing type, auction versus fixed price, starting price, buy it now enabled, end date, scheduled end date, final price, shipping details, etc.
The auction details database 312 may contain general information about past auction details, such as, for example, seller identification, listing identification, customer identification, and bid identification.
It should be noted that the term “Auction” as used herein shall be interpreted broadly to encompass listings where the buyer may close the transaction by making a single bid, also known as a buy-it-now price. Additionally, the term should also be interpreted broadly to cover fixed-price auctions, where a set price is provided for goods and multiple bids are not accepted (e.g., buyers simply purchase or not purchase the item at a set price).
A relevancy system 314 may model the propensity to close for a particular auction based on historical listing details, historical bidding activity, bidding density based on various parameters (e.g., starting price, buy it now enabled), closing price based on various parameters (e.g., starting price) and estimate time to close. The relevancy system may create a multi-variate regression model to use on future listings. The relevancy system 314 may access various submodules 316-322 to aid in performing this modeling.
A closing price submodule 316 may estimate closing price based on auctions and bid activity on those listings in similar subcategories, or on specific products when that information is available (such as through Universal Product Code (UPC) or Stock Keeping Unit (SKU) codes).
A bid value submodule 318 may estimate the propensity to attract bids, and what bids will be, based on historical bid logs for listings in similar subcategories, or on specific products when that information is available.
A will close submodule 320 may estimate the propensity that the auction will sell based on past auctions and bid activity in those auctions in similar subcategories, or on specific products when that information is available.
A time to close submodule 322 may estimate the time to close based on past auctions and bid activity in those auctions in similar subcategories, or on specific products when that information is available.
The relevancy system 314 may output one or more recommendations to a listing portal 324, which may display the one or more recommendations when a seller is creating a listing.
An ecommerce listing may be any offer for sale of a product or service on an ecommerce web site or through an ecommerce service. This may include, for example, an auction listing, or a “buy it now” listing, but also could include a more traditional product sale page such as a web page devoted to a product sold by a particular retailer through the retailer's web page or service.
As an example, if a new smartphone sells for an average price of $150 across many auctions, and auctions that end between 2 AM and 6 AM EST tend to underperform the average by 20%, while auctions that end between 8 PM and 11 PM EST tend to outperform the average by 20%, then the system can recommend that sellers configure their listings of this smartphone to end between 8 PM and 11 PM EST for an estimate $30 increase in sale price.
As another example, if a new smartphone sells for an average price of $150 across many auctions, but those with a promotional listing outperform the average by 20% and only cost the seller $5 extra, then the net benefit to the seller to purchase that promotional listing is $25. The system can recommend that particular promotional listing product to the seller, an estimate its value.
It should be noted that the recommendations may not be provided just to sellers, but also may be made to potential buyers as well. For example, buyers can be alerted to specific listings that are priced below the average. This information may be presented in a number of different ways, including email or text alerts, or an icon or notification presented next to a listing on a screen of listings, the icon or notification saying “under market price” or “good deal” or the like.
While a number of different listing configuration parameters that the system can use to make recommendations have been described above, one of ordinary skill in the art will recognize that there are other factors that may be used. The following is intended to be a non-exhaustive list of potential listing configuration parameters:
In an example embodiment, item title, condition, category, aspects, seller identification and seller segment (e.g., consumer to consumer or business to consumer) are utilized to make recommendations based on historical similar items that were sold on in the ecommerce service.
In an example embodiment, the query itself can be tuned via, for example, one or more tuning knobs presented in a user interface to administrators, which allows an administrator to vary the tightness of the query.
A seller guidance simitems client 406 may oversee the various aspects of the relevancy system, including receiving a request from a request validator 408 and passing the request, which includes an identification of an item, to the simitems client 400.
The retrieved items from the result of the query being sent to the search engine may be passed to the simitem outlier filtering 410. By reducing outlier similar items, the system is able to increase the precision of price guidance. The simitem outlier filtering 410 may be a module that is trained over time and maximize the precision of price guidance.
The simitem outlier filtering 410 may include simitem feature extraction 412, which may extract one or more features of the retrieved search engine results. The simitem outlier filtering 410 may also include a simitem classifier 414, which may predict whether the items returned from the search engine query are similar enough to the item in the original request, for the purpose of price calculation. In an example embodiment, the simitem classifier 414 may use a support vector machine (SVM) classifier. For feature sets, it may use title tokens, text similarity, category id, condition match, item cost, total cost (with shipping), watch count, bidder count, total views, and rank. The model may be trained offline based on completed items that sold. In an example embodiment, the model may be hosted in a storage service, with a cache to periodically refresh/load the model in memory. As such, any updates to the model can be automatically picked up by the service, via a simitem classifier loader 416.
While not pictured, at this point a price corrector may be use to correct for any price differentiation due to known factors, such as shipping cost. There are three main categories of items based on shipping: flat rate, free shipping, and calculated shipping. Typically the price of the free shipping items are slightly inflated to cover for the shipping costs to the seller. The price corrector can estimate what this inflation is and correct for it. Specifically, by looking at similar items with flat rate shipping, the system can compute what the percentage f the item cost is the typical shipping cost. The median such cost can be subtracted from the free shipping items cost to negate the inflation.
Price guidance 416 is then able to provide a price suggestion based on the results from the simitem classifier 414. Any number of different mechanisms can be used to derive the price. In an example embodiment, the median price of the top N similar items, as determined by the simitem classifier 414, is used.
Format guidance 418 may also be provided. One or more format metrics of similar items, perhaps the top N similar items as determined by the simitem classifier 414, may be use to recommend alterations of similar metrics in the seller listing.
In an example embodiment, price rounding may also be implemented. The result of price guidance based solely on a computed mean or median of the top N similar items may take the form of any valid real numbers (for example $13.78). In an example embodiment, these values may be rounded to a more psychologically acceptable value (for example, $13.99) that potentially results in greater adoption of the recommendation by sellers. The rounded price may have the flexibility to maximize over multiple metrics, such as conversion, average selling price, and popularity/frequency. After selecting the metric to optimize, the system may round within a certain dollar or cents threshold based on the original price. This allows an administrator to configured how aggressive he or she wants to be when rounding versus maximizing for prices for the given metric. The system may also only examine significant pricing points to remove noise.
As an example, a price recommendation service may return a figure of $24.57 and an administrator wishes to maximize conversion. Using this price, the system can look up the maximum and minimum range to round to. Since it is about $20 and less than $50, the threshold may be set to $1, so the system looks at all significant pricing points between $23.57 and $25.57. The system may find that $23.95, $23.99, $24, $24.50, $24.95, $24.99, $25, and $25.50 are significant points and out of this range the system looks up the conversion percentages for each price point and chooses the price with the maximum conversion.
At operation 502, a search query may be performed on the ecommerce service to obtain similar items that were specifically sold, using one or more of the factors/parameters described above to influence or populate the query. This may be performed using any of a number of different possible flavors for the query with varying quorum thresholds. Examples include high inverse document frequency (IDF) and kand.
At operation 504, a similar item classifier may be used to filter out outliers that may skew the prediction. At operation 506, price correction may be applied to account for an inflated price on an item offering free shipping. At operation 508, the result set may be reordered with a different sort key and sort order and the top N items may be taken to form a price and format compute set. N may be defined by a price compute size. The sort key may be, for example, score, view item count watch count, time to sell, total cost, etc).
At operation 510, the mean or median sold price of the compute set is determined. At operation 512, a majority voting technique is applied to the compute set to return the dominant format. If there is no clear majority, the system may revert to a configured default.
At operation 514, in order to determine a recommended price, the top N auction items are taken and the media or mean start price is recommended.
Notably, here the system has estimated the sale price at $108-$118 and the estimated time to sell as 2 days.
In an example embodiment, the information in the summary window 800 may be dynamically updated as the seller changes one or more of the configuration parameters 602, 604, 606, 608. Thus, for example, if the user changes one of the pricing details 606, such as duration, the system may perform an analysis of estimated sale price and time to sell based on the new duration and update these values immediately in the summary window 800.
Additionally, a specific recommendation window 802 is provided, here recommending that the user include at least 2 high resolution photos, based on the recommendations from the system.
Additionally, the specific recommendation window 802 has been updated to provide a recommendation in line with the desire to get the highest price. Here, the specific recommendation window 802 is recommending more photos than in
Certain embodiments are described herein as including logic or a number of components, modules, or mechanisms. Modules may constitute either software modules (e.g., code embodied (1) on a non-transitory machine-readable medium or (2) in a transmission signal) or hardware-implemented modules. A hardware-implemented module is a tangible unit capable of performing certain operations and may be configured or arranged in a certain manner. In example embodiments, one or more computer systems (e.g., a standalone, client or server computer system) or one or more processors 1102 may be configured by software (e.g., an application or application portion) as a hardware-implemented module that operates to perform certain operations as described herein.
In various embodiments, a hardware-implemented module may be implemented mechanically or electronically. For example, a hardware-implemented module may comprise dedicated circuitry or logic that is permanently configured (e.g., as a special-purpose processor, such as a field programmable gate array (FPGA) or an application-specific integrated circuit (ASIC)) to perform certain operations. A hardware-implemented module may also comprise programmable logic or circuitry (e.g., as encompassed within a general-purpose processor 1102 or other programmable processor 1102) that is temporarily configured by software to perform certain operations. It will be appreciated that the decision to implement a hardware-implemented module mechanically, in dedicated and permanently configured circuitry, or in temporarily configured circuitry (e.g., configured by software) may be driven by cost and time considerations.
Accordingly, the term “hardware-implemented module” should be understood to encompass a tangible entity, be that an entity that is physically constructed, permanently configured (e.g., hardwired) or temporarily or transitorily configured (e.g., programmed) to operate in a certain manner and/or to perform certain operations described herein. Considering embodiments in which hardware-implemented modules are temporarily configured (e.g., programmed), each of the hardware-implemented modules need not be configured or instantiated at any one instance in time. For example, where the hardware-implemented modules comprise a general-purpose processor 1102 configured using software, the general-purpose processor 1102 may be configured as respective different hardware-implemented modules at different times. Software may accordingly configure a processor 1102, for example, to constitute a particular hardware-implemented module at one instance of time and to constitute a different hardware-implemented module at a different instance of time.
Hardware-implemented modules can provide information to, and receive information from, other hardware-implemented modules. Accordingly, the described hardware-implemented modules may be regarded as being communicatively coupled. Where multiple of such hardware-implemented modules exist contemporaneously, communications may be achieved through signal transmission (e.g., over appropriate circuits and buses that connect the hardware-implemented modules). In embodiments in which multiple hardware-implemented modules are configured or instantiated at different times, communications between such hardware-implemented modules may be achieved, for example, through the storage and retrieval of information in memory structures to which the multiple hardware-implemented modules have access. For example, one hardware-implemented module may perform an operation, and store the output of that operation in a memory device to which it is communicatively coupled. A further hardware-implemented module may then, at a later time, access the memory device to retrieve and process the stored output. Hardware-implemented modules may also initiate communications with input or output devices, and can operate on a resource (e.g., a collection of information).
The various operations of example methods described herein may be performed, at least partially, by one or more processors 1102 that are temporarily configured (e.g., by software) or permanently configured to perform the relevant operations. Whether temporarily or permanently configured, such processors 1102 may constitute processor-implemented modules that operate to perform one or more operations or functions. The modules referred to herein may, in some example embodiments, comprise processor-implemented modules.
Similarly, the methods described herein may be at least partially processor-implemented. For example, at least some of the operations of a method may be performed by one or processors 1102 or processor-implemented modules. The performance of certain of the operations may be distributed among the one or more processors 1102, not only residing within a single machine, but deployed across a number of machines. In some example embodiments, the processor 1102 or processors 1102 may be located in a single location (e.g., within a home environment, an office environment or as a server farm), while in other embodiments the processors 1102 may be distributed across a number of locations.
The one or more processors 1102 may also operate to support performance of the relevant operations in a “cloud computing” environment or as a “software as a service” (SaaS). For example, at least some of the operations may be performed by a group of computers (as examples of machines including processors), these operations being accessible via a network (e.g., the Internet) and via one or more appropriate interfaces (e.g., application program interfaces (APIs).)
Example embodiments may be implemented in digital electronic circuitry, or in computer hardware, firmware, software, or in combinations of them. Example embodiments may be implemented using a computer program product, e.g., a computer program tangibly embodied in an information carrier, e.g., in a machine-readable medium for execution by, or to control the operation of, data processing apparatus, e.g., a programmable processor 1102, a computer, or multiple computers.
A computer program can be written in any form of programming language, including compiled or interpreted languages, and it can be deployed in any form, including as a stand-alone program or as a module, subroutine, or other unit suitable for use in a computing environment. A computer program can be deployed to be executed on one computer or on multiple computers at one site or distributed across multiple sites and interconnected by a communication network.
In example embodiments, operations may be performed by one or more programmable processors 1102 executing a computer program to perform functions by operating on input data and generating output. Method operations can also be performed by, and apparatus of example embodiments may be implemented as, special purpose logic circuitry, e.g., a field programmable gate array (FPGA) or an application-specific integrated circuit (ASIC).
The computing system can include clients and servers. A client and server are generally remote from each other and typically interact through a communication network. The relationship of client and server arises by virtue of computer programs running on the respective computers and having a client-server relationship to each other. In embodiments deploying a programmable computing system, it will be appreciated that that both hardware and software architectures require consideration. Specifically, it will be appreciated that the choice of whether to implement certain functionality in permanently configured hardware (e.g., an ASIC), in temporarily configured hardware (e.g., a combination of software and a programmable processor 1102), or a combination of permanently and temporarily configured hardware may be a design choice. Below are set out hardware (e.g., machine) and software architectures that may be deployed, in various example embodiments.
The example computer system 1200 includes a processor 1202 (e.g., a central processing unit (CPU), a graphics processing unit (GPU) or both), a main memory 1204 and a static memory 1206, which communicate with each other via a bus 1208. The computer system 1200 may further include a video display unit 1210 (e.g., a liquid crystal display (LCD) or a cathode ray tube (CRT)). The computer system 1200 also includes an alphanumeric input device 1212 (e.g., a keyboard or a touch-sensitive display screen), a user interface (UI) navigation device 1214 (e.g., a mouse), a disk drive unit 1216, a signal generation device 1218 (e.g., a speaker) and a network interface device 1220.
The disk drive unit 1216 includes a machine-readable medium 1222 on which is stored one or more sets of instructions and data structures (e.g., software) 1224 embodying or utilized by any one or more of the methodologies or functions described herein. The instructions 1224 may also reside, completely or at least partially, within the main memory 1204 and/or within the processor 1202 during execution thereof by the computer system 1200, the main memory 1204 and the processor 1202 also constituting machine-readable media 1222.
While the machine-readable medium 1222 is shown in an example embodiment to be a single medium, the term “machine-readable medium” may include a single medium or multiple media (e.g., a centralized or distributed database, and/or associated caches and servers) that store the one or more instructions 1224 or data structures. The term “machine-readable medium” shall also be taken to include any tangible medium that is capable of storing, encoding or carrying instructions 1224 for execution by the machine and that cause the machine to perform any one or more of the methodologies of the present disclosure or that is capable of storing, encoding or carrying data structures utilized by or associated with such instructions 1224. The term “machine-readable medium” shall accordingly be taken to include, but not be limited to, solid-state memories, and optical and magnetic media. Specific examples of machine-readable media 1222 include non-volatile memory, including by way of example semiconductor memory devices, e.g., erasable programmable read-only memory (EPROM), electrically erasable programmable read-only memory (EEPROM), and flash memory devices; magnetic disks such as internal hard disks and removable disks; magneto-optical disks; and CD-ROM and DVD-ROM disks.
The instructions 1224 may further be transmitted or received over a communications network 1226 using a transmission medium. The instructions 1224 may be transmitted using the network interface device 1220 and any one of a number of well-known transfer protocols (e.g., HTTP). Examples of communication networks include a local area network (“LAN”), a wide area network (“WAN”), the Internet, mobile telephone networks, plain old telephone (POTS) networks, and wireless data networks (e.g., WiFi and WiMax networks). The term “transmission medium” shall be taken to include any intangible medium that is capable of storing, encoding or carrying instructions 1224 for execution by the machine, and includes digital or analog communications signals or other intangible media to facilitate communication of such software.
Although an embodiment has been described with reference to specific example embodiments, it will be evident that various modifications and changes may be made to these embodiments without departing from the broader spirit and scope of the disclosure. Accordingly, the specification and drawings are to be regarded in an illustrative rather than a restrictive sense. The accompanying drawings that form a part hereof, show by way of illustration, and not of limitation, specific embodiments in which the subject matter may be practiced. The embodiments illustrated are described in sufficient detail to enable those skilled in the art to practice the teachings disclosed herein. Other embodiments may be utilized and derived therefrom, such that structural and logical substitutions and changes may be made without departing from the scope of this disclosure. This Detailed Description, therefore, is not to be taken in a limiting sense, and the scope of various embodiments is defined only by the appended claims, along with the full range of equivalents to which such claims are entitled.
Such embodiments of the inventive subject matter may be referred to herein, individually and/or collectively, by the term “invention” merely for convenience and without intending to voluntarily limit the scope of this application to any single invention or inventive concept if more than one is in fact disclosed. Thus, although specific embodiments have been illustrated and described herein, it should be appreciated that any arrangement calculated to achieve the same purpose may be substituted for the specific embodiments shown. This disclosure is intended to cover any and all adaptations or variations of various embodiments. Combinations of the above embodiments, and other embodiments not specifically described herein, will be apparent to those of skill in the art upon reviewing the above description.
