Definitions

  • the present invention relates to an information-processing network for a fueling station and methods of operating such an information-processing network.
  • Fueling stations comprise one or more fuel-dispenser stations each of which comprises one or more fuel dispensers for controlling dispensation of fuel from a fuel vendor's storage tank to a customer's fuel reservoir. It is known to mount fuel-dispenser information-processing devices in the fuel-dispenser stations of fueling stations. Such fuel-dispenser information-processing devices are used to perform one or more functions that may include but are not limited to controlling and/or monitoring operation of the fuel-dispenser station, enabling a customer to pay for purchases at the fuel-dispenser station with a credit card, and displaying information upon display screens of the fuel-dispenser information-processing devices.
  • Linking fuel-dispenser information-processing devices into a fueling-station information-processing network enables passing of information between each fuel-dispenser information-processing device and other information processing-devices in the fueling-station information-processing network.
  • a display screen of a fuel-dispenser information-processing device may be a 4-line display screen.
  • Such a 4-line display screen has insufficient display capabilities to display an entire web-page.
  • an information-processing device must create a reduced-content electronic-data-file by selecting information from the electronic-data-file that defines the web-page and formatting that information for display upon the 4-line display.
  • processing capabilities and computer memory to undertake the task of creating reduced-content electronic-data-files formatted for display upon whatever type of display screen the fuel-dispenser information-processing device comprises is rather expensive.
  • Known methods of operating fueling-station information-processing networks also allow customers to operate customer interfaces of the fueling-station information-processing networks to command the fueling-station information-processing network to display web-pages of their choice upon display screens of fuel-dispenser information-processing devices.
  • Enabling a customer to browse through various web-pages at the fuel-dispenser stations has advantages in that it can attract customer business by allowing them to gain valuable information such as news, weather, and driving directions.
  • Enabling a customer to browse various web-pages in such a manner can also boost revenues by exposing the customer to advertising for the fuel vendor's products and services and also by collecting fees from others who advertise products and services via display upon display screens at the fuel-dispenser stations.
  • One disadvantage to allowing a customer to browse various web-pages at the fuel-dispenser information-processing devices is that, if the customer is allowed to navigate completely unchecked, the customer may spend excessive quantities of time at the fuel-dispenser station viewing web-pages that do not contribute to increasing revenues of the fuel vendor. By spending excessive amounts of time at the fuel-dispenser station viewing web-pages, a customer reduces the revenue generating potential of the fuel-dispenser station because other potential customers are prevented from utilizing the fuel-dispenser station to purchase fuel or other goods and services.
  • a fueling-station information-processing network comprises one or more fuel-dispenser information-processing devices, each of which is mounted to a fuel-dispenser station.
  • the fueling-station information-processing network of the present invention also comprises a proxy server to which one or more of the fuel-dispenser information-processing devices are communicatively linked.
  • the fueling-station information-processing network further comprises one or more host servers each of which is communicatively linked directly or indirectly to the proxy server.
  • the invention in one form thereof comprises operating instructions according to which the proxy server operates and which are effective to verify the integrity and completeness of electronic data-files utilized by the fueling-station information-processing network. These operating instructions cause the proxy server to perform check sum operations upon electronic data-files received from the host server in order to validate the integrity and completeness of the electronic data-files. Operation of the fueling-station information-processing network in such a manner significantly reduces the probability of undesirable events occurring as a result of a malefactor, with access to an information-processing device communicatively linked to the fueling-station information-processing network, tampering with electronic data-files transmitted to the proxy server thereof.
  • the invention in another form thereof allows customers to browse web-pages that are contained in a predetermined-list of preferred web-pages stored in the proxy server, the host server, and/or other servers to which the host server may be communicatively linked.
  • one or more of the fuel-dispenser information-processing device(s) comprise display screen(s) upon which web-pages or information derived from web-pages may be displayed.
  • one or more of the fuel-dispenser information-processing device(s) comprise customer interface(s) that customers may use to communicate with the fueling-station information-processing network.
  • a customer operates one of the customer interface(s) to communicate, to the fueling-station information-processing network, a request to view a web-page of their choice or information derived from a web-page of their choice.
  • a predetermined list of preferred web-pages is stored in computer memory of the fuel-dispenser information-processing device(s), the proxy server, and/or the host server.
  • the fueling-station information-processing network After the fueling-station information-processing network receives a request from a customer to view a web-page or information derived from a web page of the customer's choice, the fueling-station information-processing network checks to see if the web-page of the customer's choice is included in the predetermined-list of preferred web-pages. If the web-page of the customer's choice is included in the predetermined-list of preferred web-pages, then the fueling-station information-processing network retrieves the web-page file corresponding to the web-page of the customer's choice and displays the web-page or a derivative thereof upon one or more of the display screen(s).
  • a fuel vendor By allowing a fuel vendor to limit the web-pages that a customer can browse, such an embodiment of the present invention allows a fuel vendor to limit the customer's browsing of web-pages to browsing of web-pages that the fuel vendor feels will contribute to increased revenues.
  • the fuel-dispenser information-processing-devices of the fueling-station information-processing network comprise two or more display screens which are of two or more different types with differing display capabilities.
  • the proxy server receives from the host server a source electronic-data-file that comprises text, graphics, and/or pictures for display upon the display screens. After receiving the source electronic-data-file, the proxy server transmits the source electronic-data-file to any fuel-dispenser information-processing device(s) that have display capabilities sufficient to allow display of the contents of the source electronic-data-file without modification.
  • the proxy server additionally creates from the source electronic-data-file one or more types of reduced-content electronic-data-file(s) by selecting a subset of the text, graphics, and/or pictures of the source electronic-data-file and formatting the selected text, graphics, and/or pictures for display upon a display screen.
  • Each type of reduced-content electronic-data-file created by the proxy server has content and formatting that is tailored for display upon one the types of display screens of the fueling-station information-processing network.
  • each type of reduced-content electronic-data-file is transmitted to fuel-dispenser information-processing-device(s) with display screens(s) that have display capabilities for which that type of reduced-content electronic-data-file is configured.
  • This embodiment of the present invention provides a cost effective way to display information from a common source electronic-data-file, such as a web-page file, upon display screens, of a fueling-station information-processing network, which have differing display capabilities.

Because the proxy server 14 removes processing burden from them, the fuel-dispenser information-processing device(s) 17 can be configured with relatively minimal processing capabilities and computer memory. Using fuel-dispenser information-processing device(s) 17 of limited sophistication is particularly cost effective for fueling-station information-processing networks 10 with many fuel-dispenser information-processing device(s) 17 .

  • the information displayed upon the display screen 13 shown in FIG. 3 c is typical of information that would be included in a reduced-content electronic-data-file tailored to a display screen 13 with very limited display capabilities.
  • the proxy server 14 may create from a source electronic-data-file a reduced-content electronic-data-file.
  • the proxy server 14 may operate according to standard file-conversion rules to create a reduced-content electronic-data-file or the proxy server may operate according to custom file-conversion rules specific to the source electronic-data-file to create a reduced-content electronic-data-file.
  • Standard file-conversion rules are operating instructions stored in computer memory of the proxy server 14 which the proxy server 14 can operate according to in order to create a reduced-content electronic-data-file from a source electronic-data-file that contains text, graphics, and/or pictures.
  • Standard file-conversion rules for creating a reduced-content electronic-data-file must be generic to a large number of possible source electronic-data-files.
  • Custom file-conversion rules are operating instructions that are received by the proxy server 14 with a source electronic-data-file and which the proxy server 14 can operate according to and create one or more reduced-content electronic-data-files from the source electronic-data-file.
  • Each set of custom file-conversion-rules for creating a reduced-content electronic-data-file may be specific to the source electronic-data-file with which it is associated.
  • Standard file-conversion rules according to which the proxy server 14 operates in order to create reduced-content electronic-data-files may have any number of forms. For purposes of understanding, a simplistic example of some standard file-conversion rules according to which a proxy server 14 may operate is included hereinafter.
  • a proxy server 14 may have stored in computer memory thereof standard file-conversion rules for creating from a source electronic-data-file, such as an HTML file, a reduced-content electronic-data-file for display upon a ⁇ fraction ( 1 / 4 ) ⁇ VGA display screen. These standard file-conversion rules could, for instance, cause the proxy server 14 to reduce the number of colors in the reduced-content electronic-data-files for the 1 ⁇ 4VGA screen as compared to the source electronic-data-file.
  • the standard file-conversion rules could further cause the proxy server 14 to always select only the first of any graphics that are included in the source electronic-data-file for inclusion in the reduced-content electronic-data-file for the 1 ⁇ 4VGA display screen.
  • the standard file-conversion rules could, further, cause the proxy server to select text including a header, a first paragraph, and a footer of the source electronic-data-file for inclusion in the reduced-content electronic-data-file for the ⁇ fraction ( 1 / 4 ) ⁇ VGA display screen.
  • Standard file conversion-rules for creating reduced-content electronic-data-files for display upon 4-line display screens would cause the proxy server 14 to select from the source electronic-data-file only four lines of text to be displayed upon the 4-line display screens.
  • standard file-conversion rules could, for instance, cause the proxy server 14 to select a header, the first two lines of body text, and a footer of the source electronic-data-file for the reduced-content electronic-data-file for display upon 4-line displays. It will be understood that the specific examples of standard file-conversion rules described herein above are included to facilitate understanding of the general nature of standard file-conversion rules for creating reduced-content electronic-data-files for display upon display screens 13 with limited display capabilities and that many other embodiments of standard file-conversion rules could be utilized by a proxy sever 14 according to the present invention.
  • the use of standard file-conversion rules by the proxy server 14 to create reduced-content electronic-data-files thus, allows for the display of valuable information derived from complex source electronic-data-files upon display screens 13 with display capabilities insufficient to display the full content of the source electronic-data-files.
  • the standard file-conversion rules specified might be such that the first paragraph and not the second paragraph of the source electronic-data-file be used in creation of a reduced-content electronic-data-file for a ⁇ fraction ( 1 / 4 ) ⁇ VGA display screen.
  • the reduced-content electronic-data-file resulting from the proxy server 14 operating in accordance with such standard file-conversion rules would be less than ideal because it would include the first paragraph and not the second. For this reason there are situations in which it is desirable that the proxy server 14 create reduced-content electronic-data-files from a source electronic-data-file by using custom file-conversion rules that are transmitted to the proxy server 14 with the source electronic-data-file.
  • Custom file-conversion rules accompanying a source electronic-data-file would be configured by the creator of the source electronic-data-file and would be a set of rules that would define which elements of the contents should be included and how those elements should be formatted in the creation of reduced-content electronic-data-files for certain types of display screens.
  • a source electronic-data-file may contain data such as text, graphics, and/or pictures and custom file-conversion rules for creating reduced-content electronic-data-files for ⁇ fraction ( 1 / 4 ) ⁇ VGA display screens and 4-line display screens.
  • the custom file-conversion rules for creating reduced-content electronic-data-files for ⁇ fraction ( 1 / 4 ) ⁇ VGA may specify to use the header text, the footer text, the second paragraph of the body text, and the second picture of the source electronic-data-file.
  • the custom file-conversion rules for creating reduced-content electronic-data-files for 4-line displays may specify to use the header text, the first two lines of the body text and the footer text from the source electronic-data-file.
  • the fueling-station information-processing network 10 is capable of creating reduced-content electronic-data-files for display upon display screen(s) 13 with limited display capabilities by using either standard file-conversion rules or custom file-conversion rules.
  • the proxy server 14 receives a source electronic-data-file with text, graphics, and/or pictures for display upon one or more display screen(s) 13 that have limited display capabilities, the proxy server 14 ascertains whether or not the source electronic-data-file is accompanied by custom file-conversion rules for the types of display screen(s) 13 upon which the information from the source electronic-data-file is to be displayed.
  • the proxy server 14 operates according to those custom file-conversion rules to create the reduced-content electronic-data-files. If there are any types of display-screen(s) 13 upon which information from the source electronic-data-file is to be displayed and for which there are no custom file-conversion rules included with the source electronic-data-file, the proxy server 14 utilizes standard file-conversion rules to create reduced-content electronic-data-files for those types of display screen(s) 13 .
  • Such a configuration and operation of a fueling-station information-processing network enables optimized configuration of information displayed upon display screen(s) 13 with limited display capabilities when custom file-conversion rules are available while ensuring that information from a source electronic-data-file can be displayed upon any types display screen(s) 13 with limited display capabilities.
