Abstract:
A software program is installed somewhere on a network and acts as a custom proxy service. The software is used to filter content returning from a source to a web browser. At an appropriate point in the returning data stream, non-selectable content, such as, for example a corporate logo, or selectable content, such as, for example, a linking to other document sources or a print function, is injected. If the selectable content requires support processing, the software program installed on the network will process the selectable content and provide an end user with the processed information without requiring the end user&#39;s downloading device to process the downloaded information.

Description:
BACKGROUND OF THE INVENTION 
     1. Field of the Invention 
     This invention relates to web page applications. 
     2. Description of Related Art 
     Currently, it is well known to access information including downloadable information on distributed networks, such as, for example, the Internet and, more particularly, the World Wide Web portion of the Internet, using an information retrieval system, such as, for example, a computer or personal digital assistant (PDA) equipped with a web browser. Downloadable information can include, for example, files, folders, documents, pictures, movies, sounds, or the like. Additionally, downloadable information can be a part of the body of an accessed web page. Alternatively, the downloadable information can be in the form of a photograph, icon, symbol, hypertext, or other link to another web page. To access the contents of a particular linked web page, the link must be separately selected to access and open the linked web page. Once the link is selected and the linked web page is opened, a separate window containing the contents of the linked web page is downloaded to the user&#39;s computer or PDA and displayed. In certain instances, the downloadable information may require opening a separate application program before the downloadable information can be displayed. 
     Generally, when a link or other downloadable information is selected, the link or other downloadable information is accessed and downloaded to a memory portion of the computer or PDA that is being used to access the link or other downloadable information. 
     If the user desires to print or output the downloaded information, a job containing the downloaded information must be built. Ordinarily, building jobs from web-based documents requires downloading to the local workstation all of the desired information from the particular web site containing the information. Software embedded in the user&#39;s computer or PDA is then used to assemble the information into a job. Once the job has been assembled, the job is sent to an appropriate output device. 
     SUMMARY OF THE INVENTION 
     Often, downloadable information is, or contains, large files. Thus, when a user attempts to access and download information, the downloadable information can consume a great deal of storage space on the user&#39;s computer. Furthermore, when the user attempts to print or output the downloaded information, the performance of the user&#39;s computer is unnecessarily slowed while the downloaded information is compiled into a job, as described above. 
     Not only is the process of building a job tedious, but the storage and bandwidth required by the user&#39;s computer or PDA can be significant. Therefore, if the user attempts to access other information while the job is being built or output, not only is the output rate of the computer or PDA slowed, but the rate at which the computer or PDA accesses additional information is slowed as well. Thus, until the output job is built and output, the user&#39;s computer or PDA accesses information at a rate that is slower than the optimum rate of the computer or PDA. This problem is compounded when the downloadable information requires a separate application program to view the downloadable information. 
     Accordingly, this invention provides systems, methods, and graphical user interfaces that allow distributed network users to download information without needlessly consuming storage space on, or slowing the operation of, the user&#39;s computer or PDA. 
     The systems, methods, and graphical user interfaces of this invention provide a software program that is installed somewhere on a network to act as a custom proxy server. This software program is used to filter all of the information that is returned from an information source, such as a web page, to a web browser. At an appropriate point in the returning data stream, specific content is injected into the returned information. By merely directing the web browser to this proxy server, the user is able to receive the injectable content. 
     The systems, methods, and graphical user interfaces of this invention provide both non-selectable injectable content and selectable injectable content that is transparently delivered into a user&#39;s web browser. The non-selectable injectable content includes displayed icons, symbols, trademarks, or the like, such as, for example, a corporate logo. In contrast, selectable injectable content can be represented by icons, buttons, selectable images, or the like, which represent an underlying function to be performed. In various exemplary embodiments, these underlying functions include, for example, print services, job build services, links to other document sources, data reduction, information filtering, and the like. The selectable injected content can be used as a portal to other information and document sources, can be used to download information, or can be used to perform calculations, data reductions or other information filtering operations. 
     In one exemplary embodiment, if a user selects a print services selectable content icon while viewing a particular web page, any data link, or uniform resource locator (URL) on the web page that point to a printable document will be added to a print list. The print list is then displayed as a new web page in the user&#39;s web browser. 
     The new web page includes a print button that allows the user to send any number of the listed documents to an appropriate storage or output device as a job. Each uniform resource locator (URL) in the print list is preceded by a selectable check-box to indicate its inclusion in the job. The appropriate storage or output device receives the job without routing the contained data through the user&#39;s computer or PDA. 
     In the event that the software used to process the documents is embedded, that is, it resides in the user&#39;s computer or PDA, the documents may be sent to a local device or any other appropriate destination on the network. 
     This invention separately provides systems and methods to decrease the amount of storage space that a given job consumes on the user&#39;s computer or PDA. 
     This invention separately provides systems and methods to increase the speed and efficiency of the user&#39;s computer or PDA as the user accesses downloadable information on a distributed network. 
     This invention separately provides systems, methods and graphical user interfaces for a download and output information option that allows the user to download and output information having a substantially simple and user-friendly design. 
     This invention separately provides systems and methods that allow an output device to receive an output job without routing the data contained in the output job through a user&#39;s computer or PDA. 
     This invention separately provides systems and methods that allow non-selectable and/or selectable content to be transparently delivered into a user&#39;s web browser. 
     This invention separately provides systems and methods that allow information viewing and editing without the need for additional software to be embedded in a user&#39;s computer or PDA. 
     This invention separately provides systems and methods that allow print jobs to be built from web-based document sources without installing additional software on a user&#39;s computer or PDA. 
     This invention separately provides systems and methods that allow print jobs to be built from web-based document sources without the need for a powerful computer or PDA. 
     This invention separately provides systems and methods that can be used to develop a networked stand-alone scanner offering scan-net/print/fax/e-mail capability. 
     These and other features and advantages of this invention are described in or are apparent from the following detailed description of the exemplary embodiments.

     In the various exemplary embodiments described herein, the computer or PDA  100  interfaces, for example, with the network  300 , or a particular node  400  of the network  300 , through the direct wired connection using the input/output interface  130 . Alternatively, the computer or PDA  100  can interface with the network  300  or a particular node  400  of the network  300 , through the linked connection  105 . The linked connection  105  can be any known or later developed device or system for connecting the computer or PDA  100  to the network  300  or a particular node  400  of the network  300 , including a wireless link, a connection over a LAN, a WAN, or any other distributed network, a connection over the public switched telephone network, a connection over a coaxial cable (i.e., CATV) system, a connection over a cellular telephone network, a satellite connection or the like. In general, the linked connection  105  can be any known or later developed connection system or structure usable to connect the computer or PDA  100  to the network  300  or a particular node  400  of the network  300 , including both wired and wireless connections. 
     The proxy server  200  includes at least some of an input/output interface  210 , a controller  220 , a memory  230 , a content monitoring circuit  240 , a content database  250 , and a content injection circuit  260 . The proxy server  200  interfaces with the network  300  through the input/output interface  210 . Additionally, the proxy server  200  interfaces with the computer or PDA  100  through the input/output interface  210  and network  300 . 
     In various exemplary embodiments, the memory  230  can be implemented using any appropriate combination of alterable, volatile or non-volatile memory or non-alterable, or fixed, memory. The alterable memory, whether volatile or non-volatile, can be implemented using any one or more of non-selectable or dynamic RAM, a floppy disk and disk drive, a writable or re-rewriteable optical disk and disk drive, a hard drive, flash memory or the like. Similarly, the non-alterable or fixed memory can be implemented using any one or more of ROM, PROM, EPROM, EEPROM, an optical ROM disk, such as a CD-ROM or DVD-ROM disk, and disk drive or the like. 
     In the various exemplary embodiments described herein, the proxy server  200  interfaces, for example, with the network  300 , or a particular node  400  of the network  300 , via a direct wired connection using the input/output interface  210 . Alternatively, the proxy server  200  can interface with the network  300  or a particular node  400  of the network  300  through the any linked connection  205 . The linked connection  205  can be any known or later developed device or system for connecting the proxy server  200  to the network  300  or a particular node  400  of the network  300 , including a wireless link, a connection over a LAN, a WAN, or any other distributed network, a connection over the public switched telephone network, a connection over a coaxial cable (i.e., CATV) system, a connection over a cellular telephone network, a satellite connection or the like. In general, the linked connection  205  can be any known or later developed connection system or structure usable to connect the proxy server  200  to the network  300  or a particular node  400  of the network  300 , including both wired and wireless connections. 
     As shown in  FIG. 1 , the memory  230  stores software including a software program that acts as a custom proxy server used by the specific content injection system  10 . The controller  220  manages reading data from and writing data to the memory  230 . Additionally, the controller  220  drives the transmission of data to and the reception of data from the network  300 , the memory  230 , the content monitoring circuit  240 , the content database  250 , and the content injection circuit  260  through the input/output interface  210 . 
     The content monitoring circuit  240  monitors incoming data from the network  300  or a particular node  400  of the network  300 . The content database  250  stores both the non-selectable and the selectable injectable content. As described above, non-selectable injectable content describes, for example, a corporate logo or a trademark that is displayed in an accessed web page. In contrast, selectable injectable content describes, for example, print services, job build services, links to other document sources, data reduction, information filtering, and the like, that is displayed in an accessed web page. The content injection circuit  260  injects the non-selectable and/or the selectable injectable content in one or more appropriate locations, as dictated by the content monitoring circuit  240 , into the incoming data from the network  300  or a particular node  400  of the network  300 . 
     In various exemplary embodiments, the specific content injection system  10  will be included as part of the software executing on a server. It should be appreciated that any other known or later developed system capable of processing and outputting data could be used in place of the server. 
     During operation of one exemplary embodiment of the specific content injection system  10 , a user browses and accesses information on the network  300  or a particular node  400  of the network  300 . In various exemplary embodiments, the information is organized in the form of web pages on the network  300  or a particular node  400  of the network  300 . As the user browses and accesses various web pages on the network  300  or a particular node  400  of the network  300 , the content monitoring circuit  240  monitors all of the information that is contained in the accessed web pages. As various web pages are accessed, the content injection circuit  260  injects the non-selectable injectable content and/or the selectable injectable content stored in the content database  250  in one or more appropriate locations in the incoming web pages. The one or more appropriate locations for the injected content is determined as described below with reference to  FIG. 2 . 
     Once the appropriate non-selectable injectable content and/or the selectable injectable content has been added to the incoming web page, the web page is transmitted, through the input/output interface  210 , to the computer or PDA  100   
     The computer or PDA  100  receives the accessed web page with the appropriate non-selectable injectable content and/or the selectable injectable content. The computer or PDA uses the browser interface  140  to transfer the accessed web page with the appropriate non-selectable injectable content and/or the selectable injectable content, through the display manager  150 , to the display  170 . 
     While reviewing the information displayed in the accessed web page, the user may wish to access any or all downloadable information displayed on that particular web page. To accomplish this, the user merely selects an appropriate selectable injected content icon for the task that the user wishes to accomplish. 
     If, for example, the user wishes to print all or a portion of the printable documents accessible from the displayed web page, the user merely selects a print services selectable injectable content icon. Once the print services selectable injectable content icon is selected, the controller  220  compiles a list in the memory  230  including each data link, or uniform resource locator (URL), on the web page that points to a printable document. The print list is then transmitted from the memory  230 , through the input/output interface  210 , to the input/output interface  130 . Once the print list is received by the input/output interface  130 , the controller  120  controls the browser interface  140  and the display manager  150  to display the print list on the display  170  as a new web page. 
     The new web page displayed on the display  170  includes the print list and a selectable menu that invites the user to select and send any number of the listed documents to an appropriate output device as a job. Once the user has selected the desired documents to be printed, the controller  220  individually and sequentially accesses each document to be printed. As each document is accessed, the controller  220  performs any processing necessary to prepare each document for printing. 
     When the desired documents are prepared, the controller  220  outputs the desired documents through the input/output interface  210  to an appropriate output device. Thus, the specific content injection systems and methods of this invention allow the user to select downloadable information from, for example, a web page on the network  300  or the particular node  400  of the network  300 , and have that downloadable information downloaded from the web page, prepared, and printed without routing the data contained in the downloadable information through the user&#39;s computer or PDA  100 . 
     In the exemplary embodiment described above, the user selects a print services selectable content icon. However, it should be understood that, in response to the user&#39;s selection of any of the selectable content icons described above, such as, for example, a link to other information and document sources icon, a download information icon, a perform calculations icon, a data reductions icon, an information filtering operations icon, or the like, the specific content injection system  10  operates to perform the selected action in the proxy server  200  so that the action does not require the user&#39;s computer or PDA  100  to perform the action. 
     It should also be understood that the actions that can be performed by the specific content injection system  10  of this invention are not limited to the actions listed above. The specific content injection system  10  of this invention can perform any actions that can be performed by software executing on a programmed general purpose computer, a special purpose computer, a microprocessor or the like. 
       FIG. 2  is a flowchart outlining one exemplary embodiment of a method for storing specific injectionable content according to this invention. In various exemplary embodiments, a user can select which specific injectionable content will be stored. Alternatively, the injectionable content to be stored can be selected by, for example, default or by the entity responsible for the memory. 
     In various exemplary embodiments, specific injectionable content includes one or more of non-selectable injectionable content, selectable injectionable content, and custom injectionable content. Non-selectable injectionable content and selectable injectionable content can include at least the injectionable content as described above. Additionally, custom injectionable content can be any additional non-selectable injectionable content or selectable injectionable content that the user desires to inject into subsequently viewed web pages. 
     As shown in  FIG. 2 , beginning in step S 100 , control continues to step S 105 , where a determination is made whether non-selectable injectable content has been selected. If, in step S 105 , non-selectable injectable content was selected, control jumps to step S 120 . Otherwise, control advances to step S 110 . 
     In step S 110 , a determination is made whether selectable injectable content has been selected. If, in step S 110 , selectable injectable content was selected, control continues to step S 120 . Otherwise, control jumps to step S 115 . 
     In step S 115 , a determination is made whether custom injectable content has been selected. If, in step S 110 , custom injectable content was selected, control jumps to step S 120 . Otherwise, control advances to step S 125 . 
     In step S 120 , all of the selected injectable content is stored. Thus, all subsequently viewed web pages include all of the selected injectable content. Control then advances to step S 125 . 
     In step S 125 , a determination is made whether a location has been selected for the injectable content. The location can be, for example, at the top or bottom of the web page, the right or left margin of the web page, or adjacent to each link on the web page that contains such links. If, in step S 125  a location for the injectable content has not been selected, control advances to step S 130 . Otherwise, control jumps to step S 135 . 
     In step S 130 , a default location for the injectable content is stored. Control then jumps to step S 140 . 
     In contrast, in step S 135 , the selected location for the injectable content is stored. Then, in step S 140 , the method ends. 
     In various exemplary embodiments, the specific injectable content can be stored in a memory, such as, for example, the memory  230  of the proxy server  200  described above with reference to  FIG. 1 . 
       FIG. 3  is a flowchart outlining one exemplary embodiment of a method for injecting specific content into a web document according to this invention. It should be understood that prior to initiating the method outlined in  FIG. 3 , specific injectionable content is associated with a proxy server as outlined above with reference to  FIG. 2 . In  FIG. 3 , the method begins when a user accesses a web page. As shown in  FIG. 3 , beginning in step S 200 , control continues to step S 205 , where content in the form of, for example, a web page, is received. Then, in step S 210 , the received web page is analyzed for a tag representing a location on the web page where the injectable content is to be inserted. In step S 215 , a determination is made whether a tag has been found on the received web page. If, in step S 215 , no tag is found on the web page, control advances to step S 220 . Otherwise, control jumps to step S 225 . 
     In step S 220  the unmodified web page is forwarded to the user. Control then jumps to step S 250 . 
     In contrast, in step S 225 , the injectable content is inserted at the tag. Then, in step S 230 , the received web page is analyzed for another tag representing another location on the web page where the injectable content is to be inserted. Next, in step S 235 , a determination is made whether another tag has been found on the received web page. If, in step S 235 , another tag is found on the web page, control advances to step S 240 . Otherwise, control jumps to step S 245 . 
     In step S 240 , the injectable content is inserted at the additional tag. Control then returns to step S 230 . 
     In contrast, in step S 245 , the modified web page is forwarded to the user. Then, in step S 250 , the method ends. 
       FIG. 4  shows a first exemplary embodiment of a graphical user interface useable to display options for selecting injectable content to be included on a web page according to this invention. As shown in  FIG. 4 , the graphical user interface  500  includes a selection portion  510 . The selection portion  510  includes at least one of a non-selectable injectable content selection portion  520 , a selectable content portion  530 , and a non-selectable injectable content portion  540 . 
     As shown in  FIG. 4 , the injectable content selection portion  515  includes a plurality of enable widgets  520 . In particular, the plurality of enable widgets  520  include a enable widget  522  that allows the user to enable an “add non-selectable injectable content” function, a enable widget  524  that allows the user to enable an “add selectable injectable content” function, and a enable widget  526  that allows the user to enable an “add custom injectable content” function. 
     In various exemplary embodiments, the selection portion  510  also includes the selectable content portion  530 . The selectable content portion  530  includes at least some of a plurality of enable widgets  532  and a plurality of enable widgets  538 . In particular, the plurality of enable widgets  532  include at least some of a enable widget  533  that allows the user to select an “add as icon” function, a enable widget  534  that allows the user to select an “add as text” function, or a enable widget  535  that allows the user to select an “add as icon and text” function. The selectable content portion  530  of the graphical user interface  500  can be implemented, for example, in step S 125  as described above with respect to  FIG. 2 . 
     If the user selects the “add as icon” function, the selectable content will be added to subsequent web pages and will be represented by an icon, such as, for example, the standard icon for a print function, a printer, to represent the print services selectable content icon as described above. If the user selects the “add as text” function, the selectable content will be added to subsequent web pages and will be represented by text, such as, for example, the word “print” to represent the print services selectable content function as described above. Additionally, if the user selects the “add as icon and text” function, the selectable content will be added to subsequent web pages and will be represented by both an icon and text, such as, for example, the standard icon for a print function with the word “print” to represent the print services selectable content function as described above. 
     As shown in  FIG. 4 , each of the plurality of enable widgets  538  corresponds to a selectable content function that can be selected by the user. For each of the selectable content functions that is selected, a corresponding selectable content function is added to each subsequent wed page as described above with reference to  FIG. 3 . 
     In various exemplary embodiments, the selection portion  510  also includes the non-selectable injectable content portion  540 . The non-selectable injectable content portion  540  includes at least some of a plurality of enable widgets  542  and a plurality of enable widgets  548 .

     It should be appreciated that, for simplicity and clarification, the embodiments of this invention have been described with reference to printing downloadable information. However, it should be appreciated that the systems and methods of this invention can be implemented not only to print downloadable information but also to perform other functions on downloadable information, such as, for example, saving downloadable information to a specific memory location or forwarding downloadable information to a particular recipient or E-mail account. 
     It should also be appreciated that the term “web page” is for basic explanation and understanding of the operation of the specific content injection system. Therefore, the term “web page” is not to be construed as limiting a user&#39;s ability to access and/or display other forms of information available on a network and to inject specific content into these other forms of displayable information. 
     It should be understood that each of the elements of the specific content injection system  10  shown in  FIG. 1  can be implemented as portions of a suitably programmed general purpose computer. Alternatively, each of the elements of the specific content injection system  10  shown in  FIG. 1  can be implemented as physically distinct hardware circuits within an ASIC, or using a FPGA, a PDL, a PLA or a PAL, or using discrete logic elements or discrete circuit elements. The particular form that each of the elements of the specific content injection system  10  shown in  FIG. 1  will take is a design choice and will be obvious and predicable to those skilled in the art. 
     Moreover, the specific content injection system  10  can be implemented as software executing on a programmed general purpose computer, a special purpose computer, a microprocessor or the like. In this case, the specific content injection system  10  can be implemented as a routine embedded in a network client, as a resource residing on a network server, or the like. The specific content injection system  10  can also be implemented by physically incorporating it into a software and/or hardware system, such as the hardware or firmware systems of another personal digital assistant, bi-directional pager, analog or digital cellular phone or the like. 
     Thus, in summary, the specific content injection system  10  can be implemented on a programmed general purpose computer, a special purpose computer, a programmed microprocessor or microcontroller and peripheral integrated circuit elements, an ASIC or other integrated circuit, a digital signal processor, a hardwired electronic or logic circuit such as a discrete element circuit, a programmable logic device such as a PLD, PLA, FPGA or PAL, or the like. In general, any device, capable of implementing a finite state machine that is in turn capable of implementing the flowcharts shown in  FIGS. 2 and 3  and/or the graphical user interfaces shown in  FIGS. 4–12 , can be used to implement the specific content injection system  10 . 
     While this invention has been described in conjunction with the exemplary embodiments outlined above, it is evident that many alternatives, modifications and variations will be apparent to those skilled in the art. Accordingly, the exemplary embodiments of the invention, as set forth above, are intended to be illustrative, not limiting.
