FIELD OF THE INVENTION
Embodiments of the present invention comprise methods and systems for imaging device operation and in particular, sending content to a client browser within an Imaging Device (IDev).
BACKGROUND
Imaging devices such as printers, copiers, scanners and fax machines can have a wide array of functions and capabilities to fit specific uses or combinations of uses. Imaging devices often take the form of a multi-function peripheral device (MFP) that combines the functions of two or more of the traditionally separated imaging devices. An MFP may combine any number of imaging devices, but typically comprises the functions of a printer, scanner, copier and fax machine.
Some imaging devices may contain computing resources for data storage and processing such as processors, hard disk drives, memory and other devices. As imaging devices add more features and functions, they become more costly and complex.
More complex imaging devices and MFPs may comprise network connectivity to provide communication with other computing devices, such as personal computers, other imaging devices, network servers and other apparatus. This connectivity allows the imaging device to utilize off-board resources that are available on a connected network.
Imaging devices typically have a user input panel with an array of buttons, knobs and other user input devices. Some devices also have a display panel, which can be for display only or can be a touch panel display that enables user input directly on the display.
Devices with touch panel displays or displays with buttons arranged in cooperation with the display can display menu data that may be selected by user input. This menu data is typically driven by an on-board server module within the imaging device.

DETAILED DESCRIPTION OF EXEMPLARY EMBODIMENTS
Embodiments of the present invention will be best understood by reference to the drawings, wherein like parts are designated by like numerals throughout. The figures listed above are expressly incorporated as part of this detailed description.
It will be readily understood that the components of the present invention, as generally described and illustrated in the figures herein, could be arranged and designed in a wide variety of different configurations. Thus, the following more detailed description of the embodiments of the methods and systems of the present invention is not intended to limit the scope of the invention but it is merely representative of the presently preferred embodiments of the invention.
Elements of embodiments of the present invention may be embodied in hardware, firmware and/or software. While exemplary embodiments revealed herein may only describe one of these forms, it is to be understood that one skilled in the art would be able to effectuate these elements in any of these forms while resting within the scope of the present invention.
Embodiments of the present invention comprise interfaces and architecture that integrate imaging devices with remote computing device applications and environments to provide solutions that may not be possible solely with an imaging device alone. Some embodiments comprise an infrastructure and set of interfaces that allow applications on a network to programmatically control imaging device functions and interact with a user through an imaging device input panel. Software functions that are not practical within the imaging device can be performed on the server but are accessible from the imaging device.
For the purposes of this specification and claims, an imaging device (IDev) may be described as a device that performs an imaging function. Imaging functions comprise scanning, printing, copying, image transmission (sending and receiving), image conversion and other functions. Exemplary imaging devices comprise printers, copiers, facsimile machines, scanners, computing devices that transmit, convert or process images and other devices. An IDev may also perform multiple imaging functions. For example, and not by way of limitation, a multi-function peripheral device (MFP), which typically has the capability to perform a plurality of functions comprising a printer, scanner, copier and/or a facsimile machine or image transmitter/receiver, is a type of imaging device. Other MFP imaging devices may comprise other combinations of functions and still qualify as an IDev.
For the purposes of this specification and claims, a remote computing device (RCD) is a device capable of processing data and communicating with other devices through a communications link. An RCD is a remote device because it requires a communications link, such as a network connection, a telephone line, a serial cable or some other wired or wireless link to communicate with other devices such as an imaging device. Some exemplary RCDs are network servers, networked computers and other processing and storage devices that have communications links.
Some embodiments of the present invention may be described with reference to FIGS. 1 & 2. These embodiments comprise an imaging device (IDev) 4 that may be a multi-function peripheral device (MFP) or a single function device. The imaging device 4 further comprises a user interface (UI) panel 2, which may comprise input buttons 14 and a display device 13 or may comprise a touch panel system with or without buttons 14. User input and display may also be performed through a separate UI device 8, which may be connected to the imaging device 4 by a communication link 12, such as a USB connection, a network cable, a wireless connection or some other communications link. UI device 8 may comprise an input device, such as a keyboard or buttons as well as a display device, which may also be a touch screen panel. UI device 8 may also comprise an interface for transfer of instructions that are input to the device 8 from a remote input device. This form of UI device 8 may comprise memory sticks, USB memory cards and other storage devices that may be configured to store input for transfer to an imaging device.
These embodiments further comprise a remote computing device (RCD) 6 that is linked to the imaging device 4 via a communications link 10, such as a network connection. This network connection may be a typical wired connection or a wireless link.
Embodiments of the present invention may provide menu data from the RCD 6 to the imaging device UI panel 2 or remote panel 8 via the network connection 10. Once this menu data is fed to the imaging device 4, an UI panel 2, 8 on the imaging device 4 may be used to interact with applications that run on the remote computing device 6. User input received from UI panels 2, 8 may be returned directly to the remote computing device 6.
A Web Service is a software application identified by a Uniform Resource Identifier (URI), whose interfaces and binding are capable of being defined, described and discovered by Extensible Markup Language (XML) artifacts and supports direct interactions with other software applications using XML based messages via Internet-based protocols.
An application on the remote computing device 6 may use one or more Web Services to control various features in the imaging device 4, such as enabling, disabling or setting device values or controlling device functions.
Embodiments of the present invention allow network applications running on remote computing devices to interact with the user of the imaging device through the imaging device I/O panel. These embodiments allow imaging device user interface (UI) control (i.e., touch panel, button/display) by applications. Some embodiments may also integrate custom display screens or menus with the native imaging device UI. Embodiments may hand off control of imaging device functions between standard operation modes performed on the imaging device in response to user input to an imaging device UI and open systems modes that utilize network resources, such as applications on RCDs, through user input at the imaging device UI.
Embodiments of the present invention comprise network-based applications that have full control over the imaging device UI to display text and graphics in any format. In these embodiments, the application can programmatically display buttons, textboxes, graphics, etc. in any layout desired.
In some embodiments, the UI layout is easy to program using a standard language, such as a markup language. These languages comprise Hypertext Markup Language (HTML), Extensible Markup Language (XML), Wireless Markup Language (WML), Extensible Hypertext Markup Language (XHTML) and other languages.
In some embodiments of the present invention a remote computing device application or server application is able to request a keyboard UI to be displayed on the imaging device display 12, 8. In some embodiments, this functionality is available on the imaging device and does not need to be recreated by remote computing device applications. In some embodiments, the remote computing device may define the keyboard prompt and default values. These embodiments may comprise a remote computing device that is able to rename imaging device UI buttons, such as the OK and Cancel buttons as well as define additional buttons.
In some embodiments, menu templates may be served to the imaging device UI by the imaging device itself 4 or from a remote computing device 6.
External Authorization Application
Some embodiments of the present invention may comprise a remote computing device application that is registered as the External Authorization server. The External Authorization application may control access to the imaging device and may have top-level control of the UI. UI control may be given to this application in the same manner that control is given to an internal auditor.
In these embodiments, when an imaging device system boots, it checks to see if an External Authorization application is registered. If so, the imaging device is placed in disabled mode and the application is contacted to take control of the UI. If the External Authorization server is not available, an error message may be displayed and the device may remain disabled. The imaging device may periodically try to contact the External Authorization server until it is available. Table 1 below describes what entity has control of the UI, in an exemplary embodiment, when the device is in a disabled state.

Remote Computing Device Applications

In embodiments of the present invention, access to the custom UI panels of imaging devices may vary from application to application. Some solutions, such as Document Management integration, may wish to leverage the native Image Send screens, but display some custom UI's to gather additional information about a scan job. Other solutions, like custom printing applications, may be accessed from a separate mode than the native functions.
In order to accommodate the diversified needs of these solutions applications, embodiments may support multiple integration points for UI control. These integration points are based on a user action (“trigger”) for which applications may register. In some embodiments, applications may be registered with target devices so that the device knows that when “trigger A” occurs on the front panel to contact “remote computing device B” for instructions. In exemplary embodiments, applications may be integrated with an imaging device at any of several “trigger” points.
Remote computing devices may be registered to a specific function and contacted when that function's hardware key is pressed (e.g. Image Send) on the imaging device UI. Any UI information provided by the remote computing device may be displayed instead of the standard function screens native to the imaging device. This trigger may be used for applications that wish to replace the existing functions with completely custom UI's, such as an alternative scan solution or a specialized display, such as a “Section 508” compatible screen or other specialized-need interface that may have large buttons or other accommodations.
In some embodiments, each function on the imaging device may have a menu on the touch screen that remote computing devices, such as servers, can register. This enables solutions applications to provide custom content and still use some of the standard functionality provided by the imaging device. When a button assigned to a custom application is selected, a menu will be displayed with the solutions registered to that function. Users may select the desired solution and the remote computing device will be contacted for instructions.
In some embodiments, a stand-alone RCD mode that provides remote computing device application access can be accessed from the job queue portion of the UI that is displayed on every screen. This trigger point may be used for applications that do not fit within one of the standard device functions, such as custom printing solutions on an imaging device. When the RCD menu is selected, a menu will be displayed with the solutions applications registered to the generic RCD mode. Users will select the desired solution and the remote computing device will be contacted for instructions.
Hardware Key Interaction
In some embodiments of the present invention, when an imaging device is enabled, additional hardware keys may be used to manage the device. Hardware key assignments for an exemplary embodiment are shown in table 2.

In some embodiments, in addition to the * key for logout, a timeout period may be implemented. Some embodiments also comprise an auto clear setting that can be configured for a given period of time, such as 10 to 240 seconds (or disabled). In these embodiments, when there is no activity for the time configured in auto clear, the device may automatically return to disabled mode and attempt to contact a remote computing device to retake control of the UI.
Error & Jam Notifications
Depending on a particular solution, a remote computing device application may have full or only partial control of the imaging device UI and a particular imaging job. In some embodiments, partial control may include cases where a remote computing device is monitoring clicks, but native modes are responsible for the UI interaction and controlling the job. Partial control may also include cases where the remote computing device application is integrated with a native mode (UI trigger=function custom menu). In these embodiments, the imaging device may handle all error and jam notifications with only a notification sent to the relevant remote computing device application.
For some embodiments, in cases where the remote computing device application has full control over the UI and the job, error and jam notifications may be handled differently depending on the type of error. For recoverable errors, a notification may be sent to the remote computing device application and the application may be responsible for displaying messages and resolving the error. For non-recoverable errors, the imaging device and RCD mode may interact to gracefully handle the error condition (e.g. provide user with instructions for clearing jam).
Control Handoffs
In some embodiments, at different points throughout an imaging job, several applications may need control over an imaging device including, but not limited to, an External Authorization application, a standard RCD application, an imaging device native mode and other applications. The following section describes, for an exemplary embodiment, the various steps in an exemplary job, the entities that may have control during each step, and what type of control may be allowed.
Step 1: User provides credentials to access the device at the device UI. This step may be controlled by a remote computing device, such as an External Authorization application or by Internal Accounting (native mode) in the imaging device itself. At the end of this step, the device is enabled. The External Authorization application may also specify default parameters or disable specific job parameters (e.g. default file format is PDF, but user may change; color mode is set to B/W and user may not change).
Step 2: User sets parameters for the job using one of the native imaging device modes or a standard RCD application. At the end of this step the user makes an input to initiate the job. When the input is made, an optional notification may be sent to the standard RCD application, which can then change job parameters if desired. An e-mail application is one example of an application that may request notification when the user input is made. A user may use native Image Send screens or other input to select scan options and choose e-mail recipients. A user may then select a custom application button and choose the scan-to-e-mail option from the menu. The e-mail application may then display custom screens for the user to set permissions for the file. Once a user places the original document(s) on the scanner and initiates the process, the e-mail application may capture the destination parameters set by the user and change the target destination to the e-mail application FTP server. The e-mail application may then receive the file, apply the appropriate permissions, and send to the e-mail recipients selected by the user. A remote computing device application may also want to retake control of the UI at this point, if, as in some embodiments, the application generates thumbnails of the scanned images and displays them to the user for verification.
Step 3: Once the job is initiated, the imaging device is responsible for scanning or RIPing the job and spooling it to the HDD. If the imaging device is configured to authorize jobs with an external authorization application, it may send a click report to the application and wait for instructions. The external authorization application may enable the job for sending/printing, cancel the job, or change job parameters (and then enable). As an example, a rules-based printing application may wish to change job parameters after it receives a click report. Some rules-based printing applications support rules-based printing and scanning that can limit what each user is allowed to do based on the time of day, the destination, or many other parameters. For example, only users in the marketing group may be able to scan high-quality color images. If a user from another group selects color and 600 dpi, a rules-based application may change the parameters to color and 200 dpi. At the end of this step the job should either be authorized or canceled.
Step 4: In some embodiments, this may be an optional step, where the standard RCD application in step 2 may have specified the destination as a HDD for temporary storage. This step may also be used, in some embodiments, by a Java application running on the imaging device. For example, a government office may have a custom encryption application running on the device that takes the scanned document, encrypts it, and then requests the imaging device to send it to the target destination selected by the user in step 2. In some embodiments, it may be beneficial to send a notification to the external authorization application after this step—because the imaging device does not know how long the file will be on the HDD or what the application is going to do with it—and after the send/print step.
Step 5: In the final step, the file is actually output. In typical embodiments, the file is either sent over the network or printed locally. At the end of this step, a notification that the job was successfully completed should be sent to the external authorization application and optionally, to the standard RCD application.
Device Control and Management API's
The API's may be used to allow a remote computing device application to control access to an imaging device for vend applications and to manage the device from a remote location.
Device Control and Vend API
In some embodiments of the present invention, a Device Control and Vend API allows applications to enable and disable access to the device and track click counts. The Device Control and Vend API may provide an RCD with the following controls:
Enable/disable device of function—this may allow an RCD to enable or disable access to the device as a whole or by function to enforce individual user privileges. In some exemplary embodiments, the functions listed in Table 3 may be selectively enabled or disabled by an application.

Debit mode—in these embodiments, when an application enables the device it may specify if the current job requires authorization. If so, the job will be spooled to memory and click information (e.g., as defined in Table 4) will be sent to an RCD. An RCD will then notify the device if the job should be deleted or output/sent. At this point, the application also has the option of changing job parameters. If the application does not require authorization, the job will continue as normal and a click report will be sent at the end of the job.
Print job accounting—in these embodiments, an RCD may wish to monitor print jobs along with walk-up functions. For print job accounting, an IDev may monitor all incoming print jobs and send accounting data in the PJL header to an RCD for verification before printing the job. The RCD will evaluate the accounting data (or lack thereof) and inform the IDev to continue with or cancel the job.
Report on unidentified jobs—in these embodiments, an RCD may also wish to monitor print jobs that it cannot associate to a specific user, such as device reports and incoming fax jobs. The RCD can register to receive click counts for all unidentified jobs, so that it may bill them to a general account.
Device Management API
In some embodiments of the present invention, a Device Management API allows a network application to remotely setup and manage the imaging device. In exemplary embodiments, the Device Management API may provide an RCD with the following controls:

    
    
        Device status—an RCD may request the current status of the device. This is the same status information as reported on the embedded web pages.
        Device configuration—an RCD can retrieve a list of installed options supported by the device.
        Web Page settings—an RCD application can retrieve and set any of the values that are configurable on the embedded web pages.
        Key Operator Programs—an RCD application can retrieve and set any of the values that are configurable in Key Operator Programs, including software keys.
        Custom Settings—an RCD application can retrieve and set any of the values that are configurable in Custom Settings.
        Job Status—an RCD application can retrieve the current job queue and history information and reprioritize or delete jobs in the queue.
        Click counts—an RCD application can retrieve device total counts and clicks for each function by account code.
        Data Security settings—an RCD application may retrieve the status information on the DSK (e.g. last erase) and initiate data clear functions.
        RED data—an RCD can retrieve all data typically sent in a RED message.
        Remote reboot—an RCD can initiate a reboot of the imaging device.
    
    


The above groupings are provided only as an exemplary embodiment detailing which settings should be included. In some embodiments, actual API's should be grouped by functional areas since there may be overlap between Key Operator settings and web page settings.
Internal Accounting API
In some embodiments, an Internal Accounting API may allow a remote computing device application to configure internal accounting and report click counts. In some exemplary embodiments an Internal Accounting API may include:

    
    
        Set Auditing Options—an RCD may set auditing options including which modes auditing is enabled for, “account number security”, and “cancel jobs of invalid accounts.”
        Manage Account Codes—an RCD can add, edit, or delete account codes
        Account Limits—an RCD application can specify a maximum number of clicks by function for individual account codes or for all account codes
        Account Reset—an RCD application can reset the click count for an individual account or for all accounts
        Retrieve Clicks—an RCD can retrieve the number of clicks by function for each account code

Font and Form Management API

    
    


Some embodiments of the present invention may comprise a Font and Form Management API, which allows an RCD application to remotely download and manage fonts and forms in mass-storage. In some exemplary embodiments, a Font and Form Management API may provide a remote computing device with the following controls:

    
    
        Mass storage control—an RCD application can retrieve mass storage status information including storage capacity, space available, and write-protect mode plus modify write-protect status.
        Resource list—an RCD application can retrieve a list of stored fonts and forms including font or macro ID, font number, font/form name, escape sequence, and file size.
        Download resource—an RCD application can download PCL fonts, PCL macros, and PS fonts and forms. Any special processing that is performed when a resource is downloaded via the web pages will also be performed when the resource is downloaded via Open Systems.
        Delete resource—an RCD application can delete any resource stored in mass storage.
        Upload resources—an RCD application can upload an individual or all resources. On devices where effective memory management is unavailable, a server application can use this function to “defrag” mass storage.
        Font/macro ID's—an RCD application can assign or modify the ID's assigned to PCL fonts and macros.

Firmware Management API

    
    


In some embodiments of the present invention, a Firmware Management API may allow a remote computing device or network application to remotely download and manage the imaging device firmware. In some exemplary embodiments, a Firmware Management API may provide a remote computing device (e.g., a server) with the following controls:

    
    
        Firmware versions—an RCD application can retrieve the current firmware version numbers.
        Service mode—an RCD application can place the MFP in service mode to lockout other jobs that will interfere with firmware upgrade. Upon receiving a service mode request, the IDev will stop accepting incoming jobs, complete all jobs in the queue, and then notify the server that it is in service mode.
        Update firmware—an RCD can download an updated firmware version to the device. If a reboot is necessary, the IDev will perform it automatically when download is complete.
        Download status—the IDev will send a status notification (success/error) to an RCD after firmware download.
        Revert to previous version—if firmware update is not successful, the application can request the IDev to revert to the previous firmware version.
    
    


Device Function API's
In some embodiments of the present invention, device function API's allow a remote computing device application to use existing imaging device functionality to provide new custom solutions.
Image Send API
In some embodiments, an Image Send API may provide the remote computing device application with the following controls:

    
    
        Image Send Parameters—a remote computing device application can get and set values for the following scan and fax parameters:
        
            COLOR OR B/W
            IMAGE MODE—TEXT, TEXT/PHOTO, PHOTO; EXPOSURE LEVEL 
            RESOLUTION 
            FILE FORMAT—FILE TYPE, COMPRESSION, AND PAGES PER FILE 
            ORIGINAL—ORIGINAL SIZE, SIMPLEX/DUPLEX, ROTATE, AND JOB BUILD 
            FILENAME 
            SUBJECT 
            MESSAGE 
            SENDER 
            SCHEDULE SEND TIME 
            PAGE DIVISION (BOOK SCANNING)
            COVER PAGE

        Initiate Scan—the remote computing device application can initiate the scan function (same as user pressing start button).
    
    


In some embodiments, a remote computing device can change the default values on the imaging device or the values for the current job. For the current job, the remote computing device may also specify if scan parameters may be modified by the user or not. If one remote computing device application (e.g. Access Control) specifies that a parameter cannot be changed and then a second application (e.g. Document Management) tries to set the parameter, a notification may be sent to the second application and the setting will not be changed.
Print API
In some embodiments, print jobs may be submitted by remote computing device applications using standard printing channels. In some exemplary embodiments, a Print API may provide a remote computing device with the following additional control:

    
    
        PJL sniffing—an RCD application can register with the IDev to be contacted for instructions when a specific PJL command is found in a print job. The RCD can then instruct the IDev to replace the command, cancel the job, or continue printing. This interface may be used in applications like accounting and other-brand compatibility.

            DOCUMENT FILING 
        
        
        Initiate Copy—an RCD application can initiate the copy function (same as user pressing start button).
    
    


In some embodiments, a remote computing device can change the default values on the imaging device or the values for the current job. For the current job, the remote computing device may also specify if copy parameters may be modified by the user or not.
Document Filing API
In some embodiments of the present invention, a Document Filing API may provide a remote computing device with the following exemplary controls:


    
    
        Backup/restore—the remote computing device application can import and export a batch file with all Document Filing data. In some embodiments, this package will be in a proprietary format since it contains documents that are password-protected and should not be accessed individually—this is typically for restore in case of failure or cloning to other devices.
        File/folder list—the remote computing device application can retrieve, modify, and create new files and folders to be stored on the IDev (also covered in device management).
        Download file—the remote computing device can download a new file to the Document Filing systems and specify folder, filename, username, and password.
        User list—the remote computing device application can retrieve, modify, and create new users to be stored on the IDev (also covered in device management).
        HDD Status—the remote computing device application can retrieve the current HDD status including the % allocated to the main folder, quick folder, and custom folders and the % remaining.
        Doc Filing Parameters—the remote computing device application can get and set values for storing a file to Doc Filing including:
        
            EXPOSURE 
            RESOLUTION 
            ORIGINAL—SIZE, SIMPLEX/DUPLEX 
            FILE INFORMATION—USERNAME, FILENAME, FOLDER, CONFIDENTIAL, PASSWORD 
            SPECIAL MODES—ERASE, DUAL PAGE COPY, 2IN1, JOB BUILD, CARD SHOT 
        
        
        Initiate Print—the remote computing device application can select a stored file and initiate a print including the following parameters:

Security
Allowing external applications to control an imaging device opens up the imaging device to new security vulnerabilities. In embodiments of the present invention that provide some security measures, the following exemplary items are security concerns that may be addressed by the remote computing device interface.
Access to remote computing device interfaces may be limited to valid applications. Embodiments provide extensive access and control of the imaging device, which poses a significant security risk. The interface of these embodiments may be protected from access by attackers, while maintaining ease of setup and use for valid solutions.
Confidential data (user credentials and job data) may be protected during network transfer. User credentials and job data may be secured during network transfer to ensure that it cannot be stolen, an intruder cannot monitor device activity, and a man-in-the-middle attack cannot change messages. Imaging devices may support Secure Sockets Layer (SSL) and other connections to ensure data is safe while being communicated between the imaging device and remote computing device applications.
Administrators may have the ability to lock-down imaging device access. For users with strict security policies, administrators may have the ability to disable access by remote computing devices or limit access to specific applications. Administrators may have an option to register the limited applications that they wish to access the imaging device interfaces.
Remote computing device applications may ensure the imaging device is not being “spoofed.” The remote computing device may be able to authenticate an imaging device that it is contract with it to ensure an intruder cannot imitate the imaging device to collect network configuration and password information, monitor file/folder structures of a document management system, or spoof security settings and DSK status of the imaging device.
A remote computing device may ensure that the server is not being “spoofed.” The imaging device must be able to authenticate all remote computing devices that it is in contact with to ensure that an intruder is not spoofing the remote computing device's IP address. By pretending to be the remote computing device, an intruder could steal user credentials, redirect scanned documents, change device settings or firmware, or bring down the access control system (either to provide access to unauthorized users or initiate a denial of service attack for valid users).
Access control/vend applications may not be compromised when a remote computing device is unavailable. When the remote computing device is unavailable, it may not be acceptable to provide open access to the device. If the remote computing device is unavailable at startup or becomes unavailable at anytime (e.g. someone disconnects network cable), the imaging device may immediately be disabled and an error message displayed.
An administrator may be able to adjust a security level based on company and application requirements. Security requirements can have a large impact on the time it takes to develop a remote computing device application and the resources required to implement the solution. Users using some embodiments may range from a small business with one imaging device, no IT staff, and a simple scan or print application to a large government office using access control and audit trails to track all device activity. The security measures used to protect imaging device interfaces may be adjustable by the administrator to match the target environment.
The imaging device and remote computing device applications may be able to hand-off user credentials. Users may be prompted to login at multiple points throughout a job. For example, an access control application or accounting application may control total device access, the imaging device may have user authentication enabled for Image Send, and a document management application may require user login before showing a folder list. In many environments, all of these applications will use a common user database. In some embodiments, it is, therefore, desirable for the applications to pass user credentials to each other, so that each one does not have to repeat the authentication process.
Some embodiments of the present invention may be described with reference to FIG. 3. These embodiments comprise an imaging device only, which is configured to interact with a remote computing device, such as a server through a communications link. The imaging device 30 comprises a user interface 32, which comprises a user input device 34, such as a keypad, one or more buttons, knobs or switches or a touch-screen panel and a display 36, which may comprise user input device 34 in the form of a touch-screen panel.
Imaging device 30 will typically be capable of performing one or more imaging functions including, but not limited to, scanning, printing, copying, facsimile transmission (sending and receiving) and others.
These embodiments further comprise a communications link 38, which may be a wired connection (as shown in FIG. 3) comprising a network cable, a Universal Serial Bus (USB) cable, a serial cable, a parallel cable, a power line communication connection such as a HomePlug connection or other wired connections. Alternatively, the communications link 38 may comprise a wireless connection, such as an IEEE 802.11(b) compliant connection, a Bluetooth connection, an Infrared Data Association (IrDA) connection or some other wireless connection.
The operation of some imaging device embodiments may be explained with reference to FIG. 4. In these embodiments, menu data is received 40 from a remote computing device (not shown in FIG. 3), which is connected to the imaging device 30 via the communication link 38 through a wired or wireless connection. This menu data is then displayed 42 on the imaging device user interface display 36. This display of remote menu data is intended to prompt a user to make an input on the user interface input device 34.
Imaging devices of these embodiments are further configured to accept input from a user in response to a display of remote menu data and communicate 44 that user input to a remote computing device. In some embodiments, this user input data will be processed by a remote computing device. This may comprise running an application on the remote computing device. This processing may also comprise accessing and communicating data that is stored on the remote computing device.
The imaging devices of these embodiments are further configured to receive 46 data resulting from processing the user input data. This may comprise data generated by an application running on the remote computing device in response to the user input. The imaging device may also receive data that was stored on a remote computing device, such as a file server, in response to processing the user input.
Once the imaging device 30 has received 46 the processed data, the imaging device 30 may perform 48 a native function in response to the data or using the data. For example, and not be way of limitation, the imaging device 30 may print a document that was stored on the remote computing device and modified on the remote computing device according to the user input. As another non-limiting example, the imaging device 30 may active or enable functions (i.e., scanning, copying, printing, fax transmission) on the imaging device in response to the receipt 46 of processed data.
Some, more specific, imaging device embodiments may be explained with reference to FIG. 5. In these embodiments, the imaging device 30 is configured to receive 50 menu data formatted in a markup language from a remote computing device. The communication link by which the menu data is communicated may be established and maintained using a Hypertext Transfer Protocol (HTTP). The markup language may comprise terms from Hypertext Markup Language (HTML), Extensible Markup Language (XML), Wireless Markup Language (WML), Extensible Hypertext Markup Language (XHTML) and/or other languages.
Once the menu data is received 50, it may be displayed 52 on the imaging device user interface display 36. As in previously described embodiments, the menu data is typically intended to prompt user input on imaging device user interface 32. Display 52 of the remotely-stored menu data may be accomplished with a browser application that is native to the imaging device 30.
In these embodiments, the imaging device 30 is further configured to route 54 user input received though its user interface 32 to a remote computing device. The remote computing device that receives the user input may then run an application or otherwise process the user input and return the results of the processing to the imaging device 30. Accordingly, the imaging device 30 is further configured to receive 58 processed data from a remote computing device. In some embodiments, the imaging device 30 may perform one or more functions in response to the receipt 58 of processed data.
Some embodiments of the present invention may be explained with reference to FIG. 6. These embodiments comprise a remote computing device (RCD) 60, which has a communications link 64. Communications link 64 may be a wired connection (as shown in FIG. 6) comprising a network cable, a Universal Serial Bus (USB) cable, a serial cable, a parallel cable, a powerline communication connection such as a HomePlug connection or other wired connections. Alternatively, the communications link 64 may comprise a wireless connection, such as an IEEE 802.11(b) compliant connection, a Bluetooth connection, an Infrared connection, such as those defined in the Infrared Data Association (IrDA) standard or some other wireless connection. In some embodiments, RCD 60 may further comprise a data storage device 62, which is typically a hard drive, but may also be an optical drive device, such as an array of compact disk drives, flash memory or some other storage device.
Embodiments of RCD 60 may be further described with reference to FIG. 7. In these embodiments, RCD 60 comprises a processor 72 for processing data and running programs such as operating systems and applications. RCD 60 may further comprise memory 74, which may be in the form of Random Access Memory (RAM) and Read Only Memory (ROM). Generally, any applications processed by processor 72 will be loaded into memory 74. RCD 60 may further comprise a network interface 78, which allows RCD 60 to communicate with other devices, such as an imaging device 30. In some embodiments, RCD 60 may also comprise a user interface 80, but this is not required in many embodiments. Storage 62 may be used to store applications and data that may be accessed by an imaging device 30 of embodiments of the present invention. Processor 72, memory 74, storage 62, network interface 78 and, optionally, user interface 80 are typically linked by a system bus 76 to enable data transfer between each component. Communications link 64 may couple the RCD 60 to other devices via network interface 78.
In some embodiments, described with reference to FIG. 8, an RCD 60 may comprise menu data stored on storage device 62 or in memory 74. This menu data may be configured for display on an imaging device user interface 32. Menu data may be stored in many formats and configurations. In some embodiments menu data may take the form of terms expressed with a markup language. The markup language may comprise terms from Hypertext Markup Language (HTML), Extensible Markup Language (XML), Wireless Markup Language (WML), Extensible Hypertext Markup Language (XHTML) and/or other languages. In these embodiments, menu data may be sent 82 through a communications link 64 to an imaging device 30. Accordingly, menu data configured for display on an imaging device is stored on RCD 60.
An RCD 60, of some embodiments, will be further configured to receive 84 user input obtained through the user interface 32 of an imaging device 30 and transferred to the RCD 60 over communications links 38 & 64. Once this input data is received at an RCD 60, the input data may be processed 86. This processing 86 may comprise conversion of the data to a new format, execution of commands contained within the data or some other process. Once the input data has been processed 86, the processed output may be sent 88 back to the imaging device 30 where the processed output may be used in an imaging device process or function.
In some embodiments, as described with reference to FIG. 9, an RCD 60 may send 90 menu data configured for an imaging device display 36 using a markup language. The markup language menu data is then received at the imaging device 30 and displayed to a user. Typically, this will prompt the user to enter an input on the imaging device user interface 32. This user input will then be sent by the imaging device 30 to the RCD 60. The RCD 60 will then receive 92 the input data prompted by the display of the menu data on the imaging device 30. Once received, the input data may be processed 94 on the RCD 60. Processing may comprise the selection, recordation and/or modification of a form, document or other data stored on RCD 60, the authorization of a user identified by the user input, the translation of a document input by the user, generation of a map or other directions related to user input or some other process or function. After this processing, the RCD 60 may send 96 the results of the processing to the imaging device 30.
Some embodiments of the present invention may be described with reference to FIGS. 10 & 11. These embodiments comprise at least one RCD 60 and a plurality of imaging devices 30a-30d. In these embodiments, at least one of the imaging devices 30a-30d comprises a user interface 32 with a display 36 and user input panel 34 that is integral with the display (i.e., touch-screen) or a separate input unit. RCD 60 is connected to imaging devices 30a-30d by a communications link and network 100 to enable data transmission between RCD 60 and imaging devices 30a-30d. 
In these embodiments, menu data is stored on RCD 60 and sent 110 to at least one of the imaging devices 30a-30d where the menu data is displayed on a user interface. Any of Imaging devices 30a-30d that receive the menu data are configured to accept 112 and transmit 114 user input to an RCD 60. Once the user input data is received at the RCD, the data may be processed 116 as discussed in previously described embodiments. The result of processing 116 may then be sent 118 back to any combination of the imaging devices 30a-30d. 
In these embodiments, a single RCD 60 may be used to provide processing power, resources and functionality to a plurality of imaging devices 30a-30d without reproducing these resources in each imaging device. In some embodiments, data generated by input on one imaging device 30a may be directed to another imaging device 30d for processed data output or final processing.
Some embodiments of the present invention may be described with reference to FIG. 12. In these embodiments, an imaging device (IDev) 120 comprises a user interface 124, which is capable of receiving user input and displaying data to a user. The user interface 124 will typically comprise a display, often in the form of a touch panel. The display may be used to display data to a user. This data may comprise menu data to prompt for a user selection or data entry, such as a user ID and password, form selection or some other input. The imaging device 120 has a communication link 122, which may comprise a typical computer network connection, a serial cable or some other wired or wireless communication link as described in other embodiments. The communication link 122 may connect the imaging device 120 to a remote computing device (RCD) 126a, 126b, such as a server. The RCD 126a, 126b may be used to store documents, such as forms, and other data and make that data accessible from the imaging device 120. The RCD 126a, 126b may also execute applications that interact with or receive input from the imaging device 120 and its user interface 124. In some embodiments, a database 125 may be linked to the imaging device 120 and/or an RCD 126a, 126b. In some embodiments, an RCD 126b or database 125 may be connected to an IDev 120 over a wide area network such as the internet 128.
Imaging Device Content Display Embodiments
Some embodiments of the present invention comprise methods and systems that provide for sending content to a client browser within an Imaging Device (IDev), using an embedded software entity. In a typical peripheral device system, web browser client applications engage in conversations with servers. The nature of these conversations is a request (browser requests a URL from the server), followed by a response (server responds by sending content to the browser). The entire conversation is made up of these request/response pairs. Typically, it is not possible to “interrupt” this conversation, or to even begin such a conversation from an outside entity. However, a condition may exist on either the client or the server that requires either party to interrupt a current conversation, or to start a new conversation, which may result in displaying an entirely different URL. This new URL may, for example, describe the condition requiring the interruption. Currently, this interruptive capability does not exist in the current art.
Embodiments of the present invention comprise methods and systems that have the capability to interrupt communication sessions between servers and web browser clients. These methods may be referred to as interruptive methods. The initial step in which a new conversation is initiated may be referred to as “pushing” content to the browser. Using these systems and methods within an IDev system allows an IDev web browser to notify a server if an error condition occurs. A system with the ability to interrupt a server application when a pre-determined error condition occurs and access content from said server can allow a group to operate more efficiently and more profitably.
Some Embodiments of the present invention provide for the pushing of content to a client browser on an IDev. In some of these embodiments, content may be pushed with a software entity referred to as a “web service,” which may operate within the MFP.
A Web Service is a software application identified by a Uniform Resource Identifier (URI), whose interfaces and binding are capable of being defined, described and discovered by Extensible Markup Language (XML) artifacts and which supports direct interactions with other software applications using XML based messages via Internet-based protocols.
The web service of these embodiments may utilize a web method that may take over the browser by showing new content. This method, whereby new browser content is pushed to a browser, may be referred to as a “ShowScreen” method. A ShowScreen method can direct a browser to display a specific URL, or it can pass textual (html, xml, etc.) content (i.e., in the form of a string) or other content for display in the browser. A ShowScreen method can be called in response to a condition raised by the MFP that may be communicated to the server via the web service. After receiving this notification, the server may push the content to the browser by calling the ShowScreen method. The browser may then show this new, unsolicited content.
Some embodiments of the present invention may comprise an imaging device (IDev) in communication with one or more additional IDevs or one or more remote computing devices (RCDs).
Some embodiments of the present invention may be described with reference to FIG. 13. These embodiments may comprise a display, 130 that is capable of displaying content and web pages from an MFP web browser 131. This content may be pushed 132 to the web browser 131 by an embedded application 133, such as a Web Service or some other software entity embedded in the MFP. The embedded application/Web Service 133 may be called by a local server 135 (i.e., on a LAN) or a remote server 138 accessed via a WAN 136, such as the Internet. The embedded application 133 may also be called by an external software application that functions as a server. In some embodiments, the embedded application/Web Service 133 may push a web page URL 132 to the MFP web browser 131. The web browser 131 may then connect to the URL to retrieve the web page. The URL may point to a resource on the original server 135, 138, the server that called the embedded application 133, or to a resource on a different server 134 & 137, which may reside on a local network 134 or at a remote location 137 through a WAN, such as the internet 136.
In these embodiments, a local server 135 may communicate with an MFP's embedded application 133. This communication may comprise pushing content, including resource URLs, to the embedded application 133 as well as receiving communications from the embedded application 133. A remote server 138 may also have bi-directional communication with the embedded application 133 in which web content, URLs and other data may be transmitted and received by the server 138 and the embedded application 133.
When an MFP's web browser 131 receives a URL 132 or some other instruction to request displayable content or some other data, the browser 131 may connect to that URL or a similar resource over a local network 134 or through a remote connection to a remote resource 137.
In some embodiments, a remote resource or server 138 or local resource or server 135 may initiate a process whereby content, or an instruction to request content, is pushed 132 to the MFP web browser 131 through an embedded application 133, such as a Web Service. This may occur while the MFP is idle or while the MFP is engaged in an unrelated process.
In some exemplary embodiments, related to those depicted in FIG. 14, a server 135, 138 may push 140 content to an MFP Web Service 133. The Web Service 133 may then push 142 the content 132 to the MFP browser 131. The MFP browser 131 may then display 144 the content on the MFP display 130. A user may then interact with the content through a user interface on the MFP 139 to terminate a process running on the MFP 139 or to initiate another process.
Some embodiments of the present invention may be described with reference to FIG. 15. These embodiments may comprise a remote application 150, which may reside on a remote server 138, which calls a Web Service 133 embedded in the MFP 139. The Web Service call may comprise a URL, browser content or some other instruction or data. The Web Service 133 may respond by obtaining content or other data 152 from a local 135 or remote location 138 when a URL or other instruction is received. This remote location may or may not be the remote server 138 that initially made the Web Service call. The Web Service may then push 154 the newly obtained content or data to the MFP Browser. The MFP web browser may then display 156 the web page.
Some embodiments of the present invention may be described with reference to FIG. 16. These embodiments comprise an external or remote application, which may reside on a local device 135 or a remote device 138. This external application may call 160 embedded software 133 in an MFP 139 and transmit instructions or content to the embedded software 133. The external application may transmit a URL or some other form of resource identifier to the embedded software. The embedded software 133 may then push 162 the URL or resource identifier to the MFP web browser. The MFP web browser may then connect 164 to the URL transmitted by the embedded application 133 and retrieve the content identified by the URL or identifier. The MFP web browser may then display 166 the retrieved content.
Some embodiments of the present invention may be described with reference to FIG. 17. These embodiments may comprise an external application on a Server “A” 135, 138 that is capable of calling 170 embedded software 133 in the MFP 139. The external application may push a resource identifier or URL to the embedded application 133. The embedded application 133 may then push 132, 172 the resource identifier or URL to the MFP web browser. The MFP web browser may then connect 174 to a URL on a separate device, server “B” 174, to retrieve the content identified by the URL or resource identifier. The MFP web browser may then display 176 the web page
Some embodiments of the present invention may be described with reference to FIG. 18. These exemplary embodiments comprise an MFP Web Service or embedded application 133 that may notify 182 a remote computing device application, such as a Server application 135, 138, of a pre-determined condition. A predetermined condition may comprise an error condition, a job status condition, an alarm or many other conditions. The Server application 135, 138 may then call 184 a Web Service method “ShowScreen” of a Web Service 133 embedded in the MFP 139. The server application 135, 138 may further transmit a URL or resource identifier to the embedded Web Service 133. The Web Service 133 may then push 186 this URL or other resource identifier to the MFP web browser 131. The MFP web browser may then connect 187 to the identified resource or URL to retrieve a web page or other content. The MFP web browser may then display 188 the identified content.
In some exemplary embodiments, related to those depicted in FIG. 19, a server 135, 138 may be notified 192 by an MFP's Web Service 133 when a MFP error condition occurs. An error condition may comprise a lack of media, a lack of toner, a lack of ink, a paper jam, a mechanical failure, an unresolved accounting restriction or some other condition. The server application 135, 138 may then call 194 an embedded application, such as a Web Service application 133 in the MFP 139. The server application 135, 138 may also send a resource identifier such as a URL to the Web Service 133 to identify specific content to be displayed on the MFP display 130. The embedded application 133 may then push 196 the URL to the MFP web browser 131. The MFP web browser 131 may then connect 197 to the URL to retrieve the web page. The MFP Web Browser may then display 198 the web page to a MFP Web Service.

This call 204 may be accompanied by browser content that is transmitted to the Web Service 133. The Web Service 133 may then push 206 this content to the MFP web browser 131. The MFP Web Browser may then display 208 the content. In some exemplary embodiments wherein the alarm condition is a fire alarm or another emergency alarm, the content transmitted to the Web Service 133 and pushed 206 to the web browser 131 may comprise an evacuation map or emergency exit instructions. When this content is displayed 208, it may be presented with an audible alarm or visually striking display to alert users to the emergency condition and inform them of the proper response procedure. In some embodiments, the emergency evacuation map or exit instruction content may be printed for user consumption. In some embodiments, the MFP may respond to receipt of the emergency response content by transmitting a facsimile message to selected recipients.
Some embodiments of the present invention, illustrated in FIG. 21, comprise embedded software in an IDev such as an MFP. This embedded software may notify 212 a server of a condition occurring on the IDev. In response, the server may call 214 web page content embedded on the IDev and push this content to the embedded software. The embedded software may then push 216 the content to the IDev web browser. The IDev web browser may then display 218 the content.
Some embodiments of the present invention, illustrated in FIG. 22, comprise a MFP Web Service 133, which is capable of notifying 222 a server “A” 135, 138 of a pre-determined condition. Server “A” may then transmit a resource identifier, such as a URL to the Web Service 133 and call 224 a Web Service method ShowScreen of the Web Service 133 embedded in the MFP 139. The Web Service 133 may then push 226 the resource identifier or URL to the MFP web browser 131 which may then connect 227 to the identified resource, which is located on a separate device, such as a server “B” 134, 137 and retrieve the identified content. The MFP browser may then display 228 the identified content.
