       FIELD OF INVENTION  
         [0002]    The present invention relates generally to computing device user interfaces, and specifically to the attenuation and amplification of user interface themes.  
         BACKGROUND OF INVENTION  
         [0003]    Some modern computing devices have a user interface that supports themes (sometimes called “skins”). A theme generally comprises a collection of related graphical images, color palettes, sounds, or other elements that a user can download and “wrap” around their device&#39;s user interface. In other words, a theme is an image or series of related images that allow users to customize the look and behavior of their computing device&#39;s user interface. Users often obtain these skins by downloading them from the Internet and installing them manually on their computers. For example, themes for Personal Digital Assistants (PDAs) are available from web sites such as http://www.pocketthemes.com/.  
           [0004]    Once a user installs a theme on his device, he has little or no control over the behavior of that theme. A theme might use animations, sound effects, or bright colors. Although a user may enjoy these features when engaged in recreational computing, all of these potentially can distract the user, particularly when he is performing more serious work. If a theme proves to be too distracting, the only solution is for the user to remove the theme, disable the theme, or switch to a different theme. If the user subsequently wishes to reactivate the theme later, he must reinstall or reenable it. Frequent installation and removal of themes is inconvenient, awkward, and labor intensive. Accordingly, there exists a need for a method and system for attenuating and amplifying user interface themes.  
         SUMMARY OF INVENTION  
         [0005]    The present invention provides a way for the user to attenuate or amplify a theme that he has installed on his device with a “theme volume control” or TVC for short. Themes may be quite animated and colorful. A user&#39;s tolerance for distraction varies. When using a device for entertainment, a user&#39;s tolerance for distraction may be higher. When using a device for academic or business work, a user&#39;s tolerance for distraction may be lower. The present invention enables a user to match a theme on a device to his tolerance level. The user can “turn down” the TVC, which could stop animations, mute colors, or stop other distractions. The user can also “turn up” the TVC, which could increase the frequency and range of animations, brighten the colors, or vary colors over time.  
           [0006]    One embodiment of the present invention comprises a device with one or more applications, a rendering system, one or more themes, and a TVC. An application presents its data and functionality to the user through a user interface. To make a user interface, the application creates a set of user interface elements. The rendering system combines this set of elements with a theme to render to the display. The rendering system uses the current TVC level to attenuate or amplify the rendition to reflect the user&#39;s selected tolerance for distraction.  
           [0007]    The features and advantages described in this summary and the following detailed description are not all-inclusive, and particularly, many additional features and advantages will be apparent to one of ordinary skill in the art in view of the drawings, specification, and claims hereof. Moreover, it should be noted that the language used in the specification has been principally selected for readability and instructional purposes and may not have been selected to delineate or circumscribe the inventive subject matter, resort to the claims being necessary to determine such inventive subject matter.

       DETAILED DESCRIPTION  
       [0019]    [0019]FIG. 1 is a diagram of a portable communication device  101 , to be used in conjunction with some embodiments of the present invention. The device  101  has an LCD display  102  (or other display type). The device  101  also has a jog wheel  103 , an escape button  104 , and a space bar  107 . In some embodiments, the device  101  has more, fewer, or similar input devices, as desired. The device  101  also has a simplified QWERTY keyboard divided into two portions, portions  105  and  106 . In other embodiments, keyboard layouts other than QWERTY can be used. Keyboard portion  105  is located on the left side of the device  101  and contains buttons  108  labeled with half (or about half) of the textual legends of a simplified QWERTY keyboard. For example, the first row of the left portion  105  of the simplified QWERTY keyboard can contain buttons  108  labeled “QWERT.” Keyboard portion  106  is located on the right side of the device  101  and contains buttons  109  labeled with the remaining textual legends of a simplified QWERTY keyboard.  
         [0020]    The jog wheel  103  (or similar input device) can be used to scroll the contents of the display  102  and move the position of the current selection; pressing the jog wheel  103  as a button can also invoke an operation in a fashion similar to pressing a button on a mouse. Selecting a name from a list of phone numbers is a pertinent example: the device user rolls the jog wheel  103  down to move the selection to a desired appropriate name. The list of names may scroll off the top of the display  102  if the name is at the bottom of the list. Once the desired name is highlighted, the user presses the jog wheel  103  to select commands for that name. The user can roll the jog wheel  103  to move the selection to the desired name. Once the desired name is highlighted, the user can press the jog wheel  103  to select commands for that name. A secondary screen, often a menu, may then be shown. The escape button  104  can be used to cancel the operation and go back to the previous screen. Textual input can be entered on the device  101  by using the buttons of keyboard portions  105  and  106 , and by using the space bar  107 .  
         [0021]    As illustrated and explained below, some embodiments of the present invention can be instantiated on devices  101  such as the one illustrated in FIG. 1. It is to be understood that the present invention can also be instantiated on other types of portable and non-portable computing devices, such as cell phones or laptop and desktop personal computers.  
         [0022]    [0022]FIGS. 2 a - 2   c  are diagrams of the device  101  running an instant messaging application with different themes applied, according to one embodiment of the present invention. FIGS. 2 a - 2   c  illustrate how the user interface of the instant messaging application changes with the application of some sample themes. FIG. 2 a  illustrates a theme based upon Beethoven. The display  102  of the device  101  shows an instant messaging application with a buddy list  201  and a title  205 . The selected name of the buddy list  201  is highlighted  207 . The display  102  of the device  101  has a picture of one of Beethoven&#39;s pianofortes in the background  203 .  
         [0023]    [0023]FIG. 2 b  illustrates a theme based upon an advertisement for a soft drink. In this example, the display  102  of the device  101  has a picture of a soft drink in the background  203 . The buddy list  201  is on the right; the title  205  is on the upper left of the display.  
         [0024]    [0024]FIG. 2 c  illustrates a theme based on space. In this example, the display  102  of the device  101  has a picture of stars in the background  203 . There is no title. The theme in FIG. 2 c  is notable because it changes the placement of the names in the buddy list  201  so that they are not displayed in a column. In addition, the space theme of FIG. 2 c  uses oval highlights  207  around the selected name in the buddy list  201 , rather than rectangles.  
         [0025]    The illustrated displays of the buddy list  201 , the highlighting of the chosen name  207 , and the title  205 , are examples of the type of changes themes can make when applied to user interfaces. It is to be understood that a virtually limitless number of possibilities exist, both for theme topics themselves and for the specific changes to be made to a user interface. Specific theme topics and associated changes are design choices, all within the scope of the present invention. It is to be understood that the themes illustrated in FIGS. 2 a - 2   c  can be attenuated or amplified as desired, according to the present invention. The attenuation and amplification of themes are discussed in detail below.  
         [0026]    [0026]FIG. 2 d  is a flowchart illustrating steps for processing a user interface theme according to one embodiment of the present invention. The instant messaging application illustrated in FIGS. 2 a - 2   c  creates  209  components to be displayed, such as a title  205 , and a buddy list  201 , including the current online status of each member of the list  201 . The application then passes  211  user interface elements representing this data to the rendering system, for combination with the user interface theme. The rendering system proceeds to combine  213  the user interface elements with the theme, and renders  215  the resulting combination to the display  102 .  
         [0027]    The manner in which the rendering system combines  213  the user interface elements with the theme is a function of the TVC level. For example, if the TVC level is high, the title  205  may be presented as an animation where the texts zooms in from the center of the display  102  and continually hops about on the top of the display  102 . The items in the buddy list  201  may each slide in from below and compress into each other as they come to a halt (an effect reminiscent of a lineup in old Keystone Cops movies). At a medium TVC level, the title  205  may animate more sedately, without continually wiggling once it comes to rest at the top of the display  102 . At this level, the list  201  items could animate as one block instead of individually. At a lower TVC level, there could be no animation, but the items of the buddy list  201  could still be colorful. The lowest TVC level would generally result in no animation and a muted color palette. One of ordinary skill in the art will readily understand that the specific manner in which the user interface elements are combined with the theme at various TVC levels is a design choice. Numerous possibilities will be apparent to those of skill in the art, all of which are within the scope of the present invention.  
         [0028]    In some embodiments of the present invention, both the application program and rendering system use XML and XSLT transforms to process the data. XML and XSLT transforms are known to those of ordinary skill in the relevant art, and are described, for example, in  Mastering XSLT,  by Chuck White, published in 2002 by Sybex, ISBN: 0782140947. Steps for processing the data according to one such embodiment are illustrated in FIG. 2 e.  The application program transforms  217  raw data into user interface elements. The rendering system transforms  219  user interface elements into a declarative markup language such as HTML, according to a theme and TVC level. In such an embodiment, a theme can be thought of as a set of transformations for all the user interface elements. Although XML, XSLT and HTML are discussed herein, these specific implementation formats serve as examples only. Other embodiments utilize other formats and markup languages, as desired.  
         [0029]    TABLE 1 is an XML file listing illustrating the application data used by an instant messaging application, according to one embodiment of the invention. XML is a known file format documented in books such as  XML in a Nutshell,  2 nd Edition,  by Jennifer Niederst, published in 2001 by O&#39;Reilly &amp; Associates, ISBN 0596001967. In TABLE 1, the instant messaging application is an instance of an &lt;application&gt; 1.01. The &lt;application&gt; 1.01 has fields such as application &lt;name&gt; 1.02 and &lt;buddylist&gt; 1.03. Each &lt;buddy&gt; 1.04 in the &lt;buddylist&gt; 1.03 has a &lt;name&gt; 1.05 and other personal data, such as an AOL Instant Messenger handle 1.06, associated with it. Of course, these fields serve as examples only. It is to be understood that in various embodiments of the device  101  other fields can be used, as desired.  
                           TABLE 1                                       1.01   &lt;application&gt;           1.02    &lt;name&gt;Buddies&lt;/name&gt;           1.03    &lt;buddylist&gt;           1.04     &lt;buddy&gt;           1.05      &lt;name&gt;Madness&lt;/name&gt;           1.06      &lt;aim&gt;madness@aol.com&lt;/aim&gt;           1.07     &lt;/buddy&gt;           1.08     &lt;buddy&gt;           1.09      &lt;name&gt;David&lt;/name&gt;           1.10      &lt;name&gt;david7865@aol.com&lt;/aim&gt;           1.11     &lt;/buddy&gt;           1.12     &lt;buddy&gt;           1.13      &lt;name&gt;Jason&lt;/name&gt;           1.14      &lt;aim&gt;xphile67@aol.com&lt;/aim&gt;           1.15     &lt;/buddy&gt;           1.16     &lt;buddy&gt;           1.17      &lt;name&gt;Emma&lt;/name&gt;           1.18      &lt;aim&gt;etc56748@aol.com&lt;/aim&gt;           1.19     &lt;/buddy&gt;           1.20     &lt;buddy&gt;           1.21      &lt;name&gt;Schnauzer&lt;/name&gt;           1.22      &lt;aim&gt;schnauzer42logic@aol.com&lt;aim&gt;           1.23     &lt;/buddy&gt;           1.24    &lt;/buddylist&gt;           1.25   &lt;/application&gt;                      
 
         [0030]    TABLE 2 is an XSLT style sheet illustrating the process that can be used to convert  217  application data into user interface elements, according to one embodiment of the invention. Application data are objects managed by the application program, such as names, addresses, part numbers, or delivery dates. User interface elements are used to create screen displays such as titles, text fields, menus, images, captions, or scrolling lists. XSLT is known file format documented in books such as  XSLT and XPath On The Edge, Unlimited Edition,  by Jeni Tennison, published in 2001 by John Wiley &amp; Sons, ISBN 0764547763. In TABLE 2, the application data are converted  217  into user interface elements following the instructions in this XLST style sheet. All of the transformations belong to one &lt;screen&gt; 2.06-2.14. The application &lt;name&gt; 1.02 is converted  217  into a &lt;title&gt;2.07-2.09 and then each &lt;buddy&gt; 1.04 in a &lt;buddylist&gt; 1.03 is enumerated inside an &lt;itemlist&gt; 2.10-2.13. Each buddy&#39;s &lt;name&gt; 1.05 is converted 217 into an &lt;entry&gt; 2.19-2.21.  
                   TABLE 2                           2.01   &lt;?xml version=“1.0” encoding=“utf-8”?&gt;       2.02   &lt;xsl:stylesheet           xmlns:xsl=“http://www.w3.org/1999/XSL/Transform”&gt;       2.03       2.04   &lt;xsl:output method=“xml”/&gt;       2.05   &lt;xsl:template match=“/”&gt;       2.06    &lt;screen&gt;       2.07     &lt;title&gt;       2.08      &lt;xsl:value-of select=“application/name” /&gt;       2.09   &lt;/title&gt;       2.10   &lt;itemlist&gt;       2.11    &lt;xsl:apply-templates select=“application/buddylist/buddy”&gt;       2.12    &lt;/xsl:apply-templates&gt;       2.13   &lt;/itemlist&gt;       2.14    &lt;/screen&gt;       2.15   &lt;/xsl:template&gt;       2.16       2.17       2.18   &lt;xsl:template match=“application/buddylist/buddy”&gt;       2.19    &lt;entry&gt;       2.20     &lt;xsl:value-of select=“name” /&gt;       2.21    &lt;/entry&gt;       2.22   &lt;/xsl:template&gt;       2.23       2.24   &lt;/xsl:stylesheet&gt;                  
 
         [0031]    TABLE 3 is an XML file listing illustrating a set of user interface elements created by the conversion  217  of application data by the XLST file listing in TABLE 2. For example, in TABLE 3, the application &lt;name&gt; 1.02 is now the &lt;title&gt; 3.02. The &lt;buddylist&gt; 1.03 is now a generic &lt;itemlist&gt; 3.03 that contains each buddy&#39;s &lt;name&gt; 1.05 as an &lt;entry&gt; 3.04. Of course, these fields serve as examples only. It is to be understood that in various embodiments of the invention other fields can be used, as desired.  
                           TABLE 3                                       3.01   &lt;screen&gt;           3.02    &lt;title&gt;Buddies&lt;/title&gt;           3.03    &lt;itemlist&gt;           3.04     &lt;entry&gt;Madness&lt;/entry&gt;           3.05     &lt;entry&gt;David&lt;/entry&gt;           3.06     &lt;entry&gt;Jason&lt;/entry&gt;           3.07     &lt;entry&gt;Emma&lt;/entry&gt;           3.08     &lt;entry&gt;Schnauzer&lt;/entry&gt;           3.09    &lt;/itemlist&gt;           3.10   &lt;/screen&gt;                      
 
         [0032]    TABLE 4 is an XSLT style sheet illustrating the process that can be used to transform  219  the user interface elements into a screen display, according to one embodiment of the invention. In this embodiment, HTML is the screen rendering technology. HTML is a known markup language and is widely documented in books such as  HTML for the World Wide Web with XHTML and CSS: Visual QuickStart Guide, Fifth Edition,  by Elizabeth Castro, published in 2002 by Peachpit Press, ISBN 0321130073. The style sheet is processed to transform  219  the user interface elements into HTML 4.05-4.12. The style sheet enumerates all objects that are children of the &lt;screen&gt; object 4.09. If there is a &lt;title&gt; object 4.14-4.19 present, then it is rendered in HTML. If there isn&#39;t a &lt;title&gt; object 4.14-4.19 present, then this template is skipped. Similarly, if there is an &lt;itemlist&gt; 4.20-4.24, then it is transformed  219  into an HTML table 4.21-4.23. Finally, each item in the &lt;itemlist&gt; 4.25-4.31 is transformed  219  into a row in the HTML table 4.26-4.30.

         [0033]    [0033]FIG. 3 is a diagram of a portable communication device  101 , with a theme applied, according to one embodiment of the present invention. The display  102  shows the output from an instant messaging application, as derived from the applied theme&#39;s XSLT style sheet shown in TABLE 4. The buddy list  201  and the title  205  have been rendered according to TABLE 4. Note that the title  205  is displayed as a vertical stripe  303 .  
         [0034]    TABLE 5 is an XSLT style sheet from a different theme that can be used as an alternative to the style sheet in TABLE 4.  
                   TABLE 5                           5.01   &lt;?xml version=“1.0” encoding=“utf-8”?&gt;       5.02   &lt;xsl:stylesheet           xmlns:xsl=“http://www.w3.org/1999/XSL/Transform”&gt;       5.03   &lt;xsl:output method=“html”/&gt;       5.04   &lt;xsl:template match=“/”&gt;       5.05    &lt;HTML&gt;       5.06    &lt;BODY&gt;       5.07     &lt;div style=“position: absolute;             top: 0;left: 0;width: 132;height: 96;       5.08      background: silver; font-family: ‘comic sans ms’; “&gt;       5.09      &lt;xsl:apply-templates /&gt;       5.10     &lt;/div&gt;       5.11    &lt;/BODY&gt;       5.12    &lt;/HTML&gt;       5.13   &lt;/xsl:template&gt;       5.14   &lt;xsl:template match=“screen/title”&gt;       5.15       5.16       5.17    &lt;center&gt;&lt;b&gt;&lt;xsl:value-of select=“/screen/title” /&gt;&lt;/b&gt;&lt;/center&gt;       5.18       5.19   &lt;/xsl:template&gt;       5.20   &lt;xsl:template match=“itemlist”&gt;       5.21    &lt;TABLE style=“font-family: ‘comic sans ms’;            line-height: 9pt;”&gt;       5.22     &lt;xsl:apply-templates /&gt;       5.23    &lt;/TABLE&gt;       5.24   &lt;/xsl:template&gt;       5.25   &lt;xsl:template match=“entry”&gt;       5.26    &lt;TR&gt;       5.27     &lt;TD&gt;       5.28      &lt;xsl:apply-templates /&gt;       5.29     &lt;/TD&gt;       5.30    &lt;/TR&gt;       5.31   &lt;/xsl:template&gt;       5.32   &lt;/xsl:stylesheet&gt;                  
 
         [0035]    [0035]FIG. 4 illustrates a display  102  on a portable communication device  101  with a theme applied as per TABLE 5. Since the XSLT style sheet TABLE 5 is a different theme, the display  102  is appropriately different. For instance, the title &lt;205&gt; is now displayed at the top of the screen instead of rotated to the right as in FIG. 3.  
         [0036]    [0036]FIG. 5 a  is a flowchart illustrating the overall operating sequence to create a screen display, according to one embodiment of the present invention. When the device  101  is turned on, an application is run and its current view is displayed  501 . The application data is converted  503  into user interface elements, according to the current view. The current Theme Volume Control (TVC) level is used to select  505  an XSLT style sheet from the current theme. In this embodiment, a theme consists of a set of XSLT style sheets that are accessed according to the current TVC level. For example, for a TVC with a scale of 1-10, there would be ten style sheets, each one corresponding to a different possible TVC level. The elements for the user interface are transformed  507  into HTML. The HTML is then rendered  509  to the display. The process repeats  511  whenever the user navigates to a new view.  
         [0037]    In other embodiments of the present invention, the rendering system uses Flash animations instead of HTML to render the display. FIG. 5 b  is a flowchart illustrating creation of a screen display, according to one such embodiment. Flash, from Macromedia, Inc., is documented in books such as  Macromedia Flash MX: Training from the Source,  by Chrissy Rey, published in 2002 by Macromedia Press, ISBN 0201794829. In embodiments that use Flash animations, the user interface elements and the TVC level are passed 513 as parameters to animations. The animations proceed to create 515-screen displays that-correspond to the user interface elements and TVC level. Of course, Flash animations are only an example of an animation format that can be used within the context of the present invention. Formats from other content authoring software tools with support for animations are utilized in other embodiments, as desired.  
         [0038]    TABLE 6 is an XSLT style sheet used in another embodiment of the present invention. In TABLE 6 there are conditional statements 6.02, 6.07, 6.12, 6.17, and 6.22 that can select different XSL statements according to the current TVC level, which in this embodiment, range from 1-6. The HTML generated from the XSLT style sheet ranges in complexity from simple text 6.03-6.05 to an instance of a Flash animation 6.23-6.30.  
                   TABLE 6                           6.01   &lt;xsl:template match=“screen/title”&gt;       6.02    &lt;xsl:if UIVC_Level = &gt;       6.03     &lt;center&gt;&lt;b&gt;       6.04      &lt;xsl:value-of select=“/screen/title” /&gt;       6.05     &lt;/b&gt;&lt;/center&gt;       6.06    &lt;/xsl:if&gt;       6.07    &lt;xsl:if UIVC_Level = 2&gt;       6.08     &lt;font color=“gray”&gt;&lt;center&gt;&lt;b&gt;       6.09      &lt;xsl:value-of select=“/screen/title” /&gt;       6.10     &lt;/b&gt;&lt;/center&gt;&lt;/font&gt;       6.11    &lt;/xsl:if&gt;       6.12    &lt;xsl:if UIVC_Level = 3&gt;       6.13     &lt;font color=“red”&gt;&lt;center&gt;&lt;b&gt;       6.14      &lt;xsl:value-of select=“/screen/title” /&gt;       6.15     &lt;/b&gt;&lt;/center&gt;&lt;/font&gt;       6.16    &lt;/xsl:if&gt;       6.17    &lt;xsl:if UIVC_Level=4&gt;       6.18     &lt;span style=“background:yellow;”&gt;&lt;font color=“red”&gt;             &lt;center&gt;&lt;b&gt;       6.19      &lt;xsl:value-of select=“/screen/title” /&gt;       6.20     &lt;/b&gt;&lt;/center&gt;&lt;/font&gt;&lt;/span&gt;       6.21    &lt;/xsl:if&gt;       6.22    &lt;xsl:if UIVC_Level = 5&gt;       6.23     &lt;OBJECT             classid=“clsid:D27CDB6E-AE6D-11 cf-96B8-444553540000”       6.24     codebase=“http://download.macromedia.com/pub/shockwave/       6.25       cabs/flash/swflash.cab#version=5,0,0,0”       6.26     WIDTH=100 HEIGHT=20&gt;       6.27     &lt;PARAM NAME=movie VALUE=“titleAnimate.swf”&gt;       6.28     &lt;PARAM NAME=quality VALUE=high&gt;       6.29     &lt;PARAM NAME=bgcolor VALUE=#FFFFFF&gt;       6.30     &lt;PARAM NAME=title VALUE=             “&lt;xsl:value-of select=“/screen/title” /&gt;”&gt;       6.31     &lt;/OBJECT&gt;       6.32    &lt;/xsl:if&gt;       6.33   &lt;/xsl:template&gt;                  
 
         [0039]    [0039]FIGS. 6 a - b  are diagrams illustrating a Start Menu  601  for a personal computer with a theme applied, according to one embodiment of the present invention. Although FIGS. 6 a - b  illustrate a Start Menu  601  for a personal computer (such as a laptop or desktop), the illustrated functionality can also be applied on portable or other computing devices  101 . In the illustrated embodiment, if the TVC level is high, small animations are inserted into the standard user interface elements. FIGS. 6 a - b  illustrate two frames of animation that occur when the user chooses an item from the Start Menu  601 . As illustrated in FIG. 6 a,  when the user chooses the Microsoft Word® entry  602 , an animated character  603  appears in the corner and pushes a detonator. As illustrated in FIG. 6 b,  an exploding menu item  605  is displayed and the animated character  603  reacts accordingly. If the TVC level is lower, then this animation would not occur. Of course, the illustrated animation is only one of many possible examples, all of which are within the scope of the present invention. It is to be understood that the animation frames illustrated in FIGS. 6 a - 6   b  can be attenuated or amplified as desired, according to the present invention.  
         [0040]    [0040]FIG. 7 is a flowchart illustrating the overall operating sequence to create a screen display, according to another embodiment of the present invention. In this embodiment, the rendering of a theme at a TVC level is controlled by messages rather than an XSLT style sheet.  
         [0041]    A personal computer application is run and its current view is displayed  501 . The application calls routines for rendering the display. These routines create messages, which are data records containing the drawing instructions. Making a plurality of these calls in sequence creates  703  a queue of these messages. The current Theme Volume Control (TVC) level is used to modify the messages  705  by adjusting the colors, animations, and other message parameters. For example, all the messages can be scanned and a palette of their colors assembled. Depending on the TVC level, the color set can be made more saturated to amplify the theme or more muted to attenuate the theme. Such image processing techniques are discussed in books such as  Digital Image Processing ( 2 nd Edition ), by Rafael C. Gonzalez and Richard E. Woods, published in 2002 by Addison-Wesley, ISBN 0201180758. Then, the messages are scanned and measured but not rendered, during a first pass to determine  707  the layout. A second pass actually renders  709  the messages to the display. The process repeats  511  whenever the user navigates to a new view.  
         [0042]    It will be readily apparent to one of ordinary skill in the relevant art that the above described methodologies can be used to attenuate and/or amplify the degree to which a theme is applied to a user interface. By adjusting the TVC level, a user can cause the screen to be redrawn with user interface elements appropriate to the selected TVC level. Thus, by turning the TVC level up, the user can amplify the application of the theme, and by turning the TVC level down, the user can attenuate the application of the theme.  
         [0043]    As will be understood by those familiar with the art, the invention may be embodied in other specific forms without departing from the spirit or essential characteristics thereof. Likewise, the particular naming and division of the modules, features, attributes, methodologies, and other aspects are not mandatory or significant, and the mechanisms that implement the invention or its features may have different names, divisions and/or formats. Furthermore, as will be apparent to one of ordinary skill in the relevant art, the modules, features, attributes, methodologies, and other aspects of the invention can be implemented as software, hardware, firmware, or any combination of the three. Of course, wherever a component of the present invention is implemented as software, the component can be implemented as a standalone program, as part of a larger program, as a plurality of separate programs, as a statically or dynamically linked library, as a kernel loadable module, as a device driver, and/or in every and any other way known now or in the future to those of skill in the art of computer programming. Additionally, the present invention is in no way limited to implementation in any specific programming language or for any specific operating system or environment. Accordingly, the disclosure of the present invention is intended to be illustrative, but not limiting, of the scope of the invention, which is set forth in the following claims.
