## Title
Side-by-side shared calendars

## Abstract

Methods and systems are provided for presenting a plurality of shared calendars in a single electronic display frame or window where each of the plurality of shared calendars is displayed in a common view mode relative to other displayed shared calendars. Users may select one or more shared calendars to be displayed in the same display frame or window as their own calendar. Upon selection of a shared calendar to be displayed alongside a first calendar, an aggregate view object is called to control and coordinate all shared calendars selected for display in the common window or frame. The aggregate view object determines the view data object, including view mode (hourly, daily, weekly, monthly) and other calendar display settings of the first or active calendar displayed in the common view of shared calendars.

## Background
FIELD OF THE INVENTION
The present invention relates to methods and systems for creating and simultaneously displaying multiple shared electronic calendars in side-by-side orientation.
BACKGROUND OF THE INVENTION
Since the advent of the computer and software age, software developers have attempted to provide helpful functionality to software users that provide useful information in a contextual nature. One useful application is the electronic calendaring application where users may enter and view appointments and other scheduling data in an electronic calendar viewable on their computer display. Electronic calendars allow users to view calendar information in a variety of different modes such as hourly, daily, weekly, monthly, and the like, or portions of days, weeks, or months.
One useful aspect of electronic calendaring systems is the ability of users to share calendaring information across a distributed computing environment with other electronic calendar users. That is, one user may give permission to a number of other users to view his or her personal or business electronic calendar data. Accordingly, the first user may select a desired calendar of a friend or colleague and display the selected calendar using the first user's calendar application. Often, a user may wish to compare her calendar data to another user's calendar data to determine whether the second user is available for a meeting at a desired date and time period. In order to compare calendars, users must toggle between two or more calendars, or users may open two calendar windows on the same display. Unfortunately, because the second or other calendar may be presented in a different mode, for example, daily, weekly, monthly, etc., the first user has a difficult or unfriendly user experience at best.
Accordingly, there is a need for a method and system for presenting multiple shared calendars in a single common display window or frame where the multiple shared calendars are presented in common views and display modes. There is further a need for a method and system for allowing quick and efficient addition and removal of shared calendars from the multiple calendar view. It is with respect to these and other considerations that the present invention has been made.
SUMMARY OF THE INVENTION
Embodiments of the present invention provide methods and systems for presenting a plurality of shared calendars in a single electronic display frame or window where each of the plurality of shared calendars is displayed in a common view mode relative to other displayed shared calendars. According to an aspect of the invention, users may select one or more shared calendars to be displayed in the same display frame or window as their own calendar. Upon selection of a shared calendar to be displayed alongside a first calendar, an aggregate view object is called to control and coordinate all shared calendars selected for display in a common window or frame. The aggregate view object determines the view data object, including view mode (hourly, daily, weekly, monthly) and other calendar display settings of the first or active calendar displayed in the common view of shared calendars.
The aggregate view determines the available display space for displaying the first calendar plus selected additional shared calendars. The aggregate view determines the size and location for any selected incoming shared calendar. The aggregate view calls each selected shared calendar for displaying in the common view of shared calendars. The aggregate view next provides each called shared calendar with the view data object of the first calendar in order to display each shared calendar in the same view mode and settings as the first calendar. The aggregate view also provides each selected shared calendar with a location and size of display.
Once each selected shared calendar is called by the aggregate view, each selected shared calendar is displayed in a common view frame or window in side-by-side orientation where each displayed shared calendar is displayed in the same view mode (hourly, daily, weekly, monthly, etc.). Each date or time position of each displayed shared calendar is aligned with corresponding date or time positions of other displayed shared calendars.
According to one aspect of the invention, selection of any of the one or more displayed shared calendars establishes the selected calendar as the active calendar. If view mode or other display settings are changed in the active calendar, the aggregate view object causes the changes in the view mode or other display settings of the active calendar to be made to all displayed shared calendars in order to keep all shared calendars in a common view mode and with common display settings.
According to another aspect, navigation controls such as time bars and scroll bars are constructed by the aggregate view object for one of the plurality of displayed shared calendars to control all displayed shared calendars simultaneously so that, for example, scrolling one shared calendar scrolls all shared calendars simultaneously. Utilization of any controls or tools of the host calendaring application is applied to each displayed shared calendar.
According to another aspect of the invention, a navigation pane is provided including a date selection control and a shared calendar selection control. Selection of a date from the date selection control displays the selected date for all displayed shared calendars simultaneously. Selection of an additional shared calendar from the shared calendar selection control causes the aggregate view object to call the selected additional shared calendar to display the selected additional shared calendar along with presently displayed shared calendars. Likewise, deletion of a shared calendar from the selected displayed shared calendars causes the aggregate view object to dismiss the deleted calendar. Addition or deletion of a shared calendar results in resizing and repositioning of remaining or resulting shared calendars by the aggregate view object to utilize all available display space.
These and other features and advantages, which characterize the present invention, will be apparent from a reading of the following detailed description and a review of the associated drawings. It is to be understood that both the foregoing general description and the following detailed description are exemplary and explanatory only and are not restrictive of the invention as claimed.

DETAILED DESCRIPTION OF THE PREFERRED EMBODIMENT
As briefly described above, embodiments of the present invention are directed to methods and systems for simultaneously displaying a plurality of shared electronic calendars in a single application window or frame where each displayed calendar is displayed in a common view mode in side-by-side orientation relative to each other. In the following detailed description, references are made to the accompanying drawings that form a part hereof, and in which are shown by way of illustrations specific embodiments or examples. These embodiments may be combined, other embodiments may be utilized, and structural changes may be made without departing from the spirit or scope of the present invention. The following detailed description is therefore not to be taken in a limiting sense and the scope of the present invention is defined by the appended claims and their equivalents.
Referring now to the drawings, in which like numerals represent like elements or components throughout the several figures, aspects of the present invention and the exemplary operating environment will be described. FIG. 1 and the following discussion are intended to provide a brief, general description of a suitable computing environment in which the invention may be implemented. While the invention will be described in the general context of an application program that runs on an operating system in conjunction with a personal computer, those skilled in the art will recognize that the invention also may be implemented in combination with other program modules. Generally, program modules include routines, programs, components, data structures, etc. that perform particular tasks or implement particular abstract data types. Moreover, those skilled in the art will appreciate that the invention may be practiced with other computer system configurations, including hand-held devices, multiprocessor systems, microprocessor-based or programmable consumer electronics, cell phones, minicomputers, mainframe computers, and the like. The invention may also be practiced in distributed computing environments where tasks are performed by remote processing devices that are linked through a communications network. In a distributed computing environment, program modules may be located in both local and remote memory storage devices.
With reference to FIG. 1, an exemplary system for implementing the invention includes a conventional personal computer 20, including a processing unit 21, a system memory 22, and a system bus 23 that couples the system memory to the processing unit 21. The system memory 22 includes read-only memory (ROM) 24 and random access memory (RAM) 25. A basic input/output system 26 (BIOS), containing the basic routines that help to transfer information between elements within the personal computer 20, such as during start-up, is stored in ROM 24. The personal computer 20 further includes a hard disk drive 27, a magnetic disk drive 28, e.g., to read from or write to a removable disk 29, and an optical disk drive 30, e.g., for reading a CD-ROM disk 31 or to read from or write to other optical media. The hard disk drive 27, magnetic disk drive 28, and optical disk drive 30 are connected to the system bus 23 by a hard disk drive interface 32, a magnetic disk drive interface 33, and an optical drive interface 34, respectively. The drives and their associated computer-readable media provide non-volatile storage for the personal computer 20. Although the description of computer-readable media above refers to a hard disk, a removable magnetic disk and a CD-ROM disk, it should be appreciated by those skilled in the art that other types of media which are readable by a computer, such as magnetic cassettes, flash memory cards, digital video disks, Bernoulli cartridges, and the like, may also be used in the exemplary operating environment.
A number of program modules may be stored in the drives and RAM 25, including an operating system 35, one or more application programs 100, such as a calendar application 200, described below. A word processor program module 37 (or other type of program module), program data, such as the manifest 38, and other program modules (not shown).
A user may enter commands and information into the personal computer 20 through a keyboard 40 and pointing device, such as a mouse 42. Other input devices (not shown) may include a microphone, joystick, game pad, satellite dish, scanner, or the like. These and other input devices are often connected to the processing unit 21 through a serial port interface 46 that is coupled to the system bus, but may be connected by other interfaces, such as a game port or a universal serial bus (USB). A monitor 47 or other type of display device is also connected to the system bus 23 via an interface, such as a video adapter 48. In addition to the monitor, personal computers typically include other peripheral output devices (not shown), such as speakers or printers.
The personal computer 20 may operate in a networked environment using logical connections to one or more remote computers, such as a remote computer 49. The remote computer 49 may be a server, a router, a peer device or other common network node, and typically includes many or all of the elements described relative to the personal computer 20, although only a memory storage device 50 has been illustrated in FIG. 1. The logical connections depicted in FIG. 1 include a local area network (LAN) 51 and a wide area network (WAN) 52. Such networking environments are commonplace in offices, enterprise-wide computer networks, intranets and the Internet.
When used in a LAN networking environment, the personal computer 20 is connected to the LAN 51 through a network interface 53. When used in a WAN networking environment, the personal computer 20 typically includes a modem 54 or other means for establishing communications over the WAN 52, such as the Internet. The modem 54, which may be internal or external, is connected to the system bus 23 via the serial port interface 46. In a networked environment, program modules depicted relative to the personal computer 20, or portions thereof, may be stored in the remote memory storage device. It will be appreciated that the network connections shown are exemplary and other means of establishing a communications link between the computers may be used.
FIG. 2 is a simplified block diagram illustrating a relationship between a host calendar application, an aggregate view object and a plurality of selected shared calendars. According to embodiments of the present invention, a calendaring application 200, such as Outlook® manufactured by Microsoft Corporation of Redmond, Wash. provides a shared electronic calendar view whereby a plurality of shared electronic calendars are displayed to the user in a common view mode and side-by-side orientation relative to each other. It should be appreciated that the calendaring application 200 includes sufficient computer executable instructions for displaying a graphical user interface containing desired calendar information. A frame module 210 includes computer executable instructions for directing the display of user interface information on the user's display screen. For example, if the user of the calendaring application 200 selects the display of the user's calendar, the frame module 210 directs the placement, orientation and display of the calendaring information. Likewise, if the user selects the display of the user's contact information via the application 200, the frame module 210 directs the display of contact information for the user. In the case of calendar views, the frame module 210 provides a selected calendar view with an appropriate view data object including the view mode of the calendar such as hourly, weekly, daily, monthly, etc. and directs the positioning of other user interface components such as tool bars, navigation panes, and the like.
According to an embodiment of the present invention, in addition to directing the display of other views 230, such as contact information, the frame module 210 directs the activities of the aggregate view object module 220. As will be described in more detail below, the aggregate view module 220 is a software module integrated with the calendaring application 200 including sufficient computer executable instructions for directing the display of multiple selected subcalendar views 240, 250, 260 in a single view frame or window in side-by-side orientation. That is, according to embodiments of the present invention, a user may select a first calendar view 240, such as the user's own calendar, followed by selection of a second calendar view 250, followed by selection of multiple additional calendars up to N selected calendars 260. As will be described below with reference to FIG. 3, each selected calendar view is displayed by the aggregate view module 220 in side-by-side orientation in a single view frame or window.
FIG. 3 illustrates a computer screen display showing an exemplary electronic calendar display showing the display of three shared calendars in a single and common display frame. As shown in FIG. 3, a calendaring application display frame 215 is illustrated. According to embodiments of the present invention, a plurality of selected calendar views 240, 250, 260 are displayed in a single view frame or window in side-by-side orientation. Also illustrated in FIG. 3 is the navigation pane 310 including a date selection control 320, a my-calendar selection control 330 and another calendars selection control 340. A time bar 350 is illustrated adjacent to the first calendar 240 and a scroll bar 375 is illustrated adjacent to the third calendar view to 260. A background color 370 is illustrated for each calendar view 240, 250, 260. A task pad (not shown) may also be provided for entering tasks applicable to a selected calendar. According to embodiments of the present invention the task pad accepts tasks for and is otherwise associated with the first selected calendar from which the view data object is obtained by the aggregate view module 220 for use with subsequently selected calendars.
Selection of any one of the shared calendars, such as by double clicking a mouse focus inside one of the display shared calendars, establishes the selected calendar as the active calendar. Subsequently, changes in the view mode of the active calendar cause like changes in the view modes of other displayed calendars. For example, if the first calendar 240 is established as the active calendar, and the user changes the first calendar 240 view mode from a single day in hourly increments to a weekly calendar, the calendar 240 will be changed to a weekly view mode, and the other displayed shared calendars 250, 260 will likewise be changed to a weekly view mode.
According to embodiments of the present invention, display of the shared calendars 250, 260 alongside the user's calendar 240 displays the data from those shared calendars under the control of the aggregate view module 220. Changes in the view mode, for example daily, weekly, monthly, etc., and changes in formatting such as font size of displayed calendaring data only makes those changes in the user's view of shared calendars. That is, if the owner of the data of a shared calendar, for example calendar 260, subsequently opens his or her calendar at his or her computer via a separate calendaring application 200, that user's calendaring data will be displayed according to the view mode, and other display settings selected by that user.
Additionally, date and time positions for each of the displayed shared calendars are kept in aligned orientation. For example, the 10:00 a.m. time position for the calendar 240 will be aligned in side-by-side orientation with the 10:00 a.m. time positions of the other displayed calendars 250, 260. Manipulation of date and time positions using controls such as the time bar 350 and the scroll bar 375 manipulates all displayed calendars 240, 250, 260 simultaneously. That is, scrolling the scroll bar 375 up or down scrolls all display calendars simultaneously while maintaining each date and time position of each displayed calendar in alignment, as described above. Generally, selection of tool bar functionality or navigation functionality affects all displayed calendars simultaneously. For example, changes in the font or other formatting of the active calendar, likewise changes the font or other formatting of other displayed calendars. Selection of a particular date from the date selection control 320 causes the display of the selected date in all displayed calendars 240, 250, 260.
As mentioned above, a my calendars selection control 330 and an other calendars selection control 340 are provided. Selection of one of the calendars provided in the my calendars selection control 330 causes the display of the selected calendar. Likewise, selection of one or more of a plurality of other calendars from the other calendars selection pane 340 causes the display of the selected calendars. As should be appreciated, the other calendars selection pane may be populated by a given user with a plurality of calendars of friends, colleagues, or other associates who have given the user permission to display their calendaring data, as described herein.
According to an embodiment of the present invention, each viewed calendar 240, 250, 260 may be displayed with a different background color 370 to distinguish displayed calendars. The background coloring 370 for the displayed calendars may likewise be utilized in the other calendars selection pane 340 to provide background coloring for selected calendars to provide the user a quick and efficient means for identifying selected calendars.
When a user creates an all day event, an all day event banner 360 is displayed. The banner appointments show up in an area at the top of the daily views, illustrated in FIG. 3. This area is above the time bar 350 and does not correspond to a particular time position. Because the banner area may be enlarged to include a plurality of banner appointments, enlargement of the banner area for any given selected calendar 240, 250, 260 causes a like enlargement of the banner area for all displayed calendars. The aggregate view module 220 inquires of each calendar view 240, 250, 260 as to how much space is required for banner appointments for the selected calendars. The aggregate view module 220 then requires space corresponding to the largest amount of required banner appointment space for each of the displayed calendars 240, 250, 260.
Having described a relationship between the calendaring application 200, the frame module 210, the aggregate view module 220 and selected calendar views 240, 250, 260 with respect to FIG. 2, and having described the user interface and other display characteristics of the shared calendar view according to embodiments of the present invention, with respect to FIG. 3, the following is a further discussion of the functionality of the aggregate view module 220. As described herein, the aggregate view module 220 hosts the plurality of selected calendar views 240, 250, 260. The aggregate view module 220 orchestrates the processes for creating, displaying, and deleting selected calendar views 240, 250, 260. Additionally, the aggregate view module hosts and directs the display of other user interface information including components of the navigation control 310.
The aggregate view module 220 coordinates the time bar 350. According to an embodiment of the present invention, selected calendar may have a time bar 350 if the calendar is in a view mode requiring a time bar. However, because each calendar is synchronized so that movement along the time positions of one calendar causes a like movement of time positions for all displayed calendars, the aggregate view module 220 displays only one time bar 350 for all displayed calendars 240, 250, 260 and hides the time bars that ordinarily would be displayed for each other displayed calendar 240, 250, 260 if the calendars are in a view mode requiring a time bar.
The aggregate view module 220 also coordinates the display of and use of the scroll bar 375. As with the time bar 350, each displayed calendar 240, 250, 260 includes a scroll bar 375 according to its individual view data object. However, the aggregate view module shows only one scroll bar 375 for scrolling each of the displayed calendars simultaneously. The aggregate view module coordinates scrolling among all calendars. Scrolling can be initiated through a number of means, including use of the scroll bar, a mouse wheel, arrow keys, and the like. Typically these events are directed to individual calendars 240, 250, 260. According to an embodiment of the present invention, if the user scrolls an individual selected calendar 240, 250, 260, the software code responsible for the individual scrolled calendar communicates the scrolling to the aggregate view module which in turn directs all other displayed calendars 240, 250, 260 to scroll in synchronized movement with the selected calendar. As described above, selection of a particular view mode for one selected calendar, such as daily, weekly, monthly, etc. likewise causes each other selected calendar to be displayed in the same view mode.
Additionally, the aggregate view module manages the utilization of space in the display frame 210 by all selected user interface components including the displayed calendars, the navigation pane 310, the time bar 350, the scroll bar 375, and the tool bar 380. That is, the aggregate view decides how to divide the visual geometry of the main display frame into the sections for each selected calendar view as well as other components such as the navigation pane 310, scroll bar 375, time bar 350 and tool bar 380. When the spatial needs require, such as when the window or frame is resized by the user, or when an additional calendar 240, 250, 260 is added or deleted, the aggregate view module 220 resizes and relocates all displayed components appropriately. Accordingly, if the user selects an additional calendar for display so that the calendar view illustrated in FIG. 3 will include four selected calendars, for example, the aggregate view module 220 will determine the space requirements for displaying the four selected calendars and will resize each selected calendar accordingly to fit each of the four selected calendars in the common view illustrated in FIG. 3. Likewise, if the user deletes a selected calendar, the aggregate view module 220 will expand the remaining selected calendars to fit the available space in which to display.
According to embodiments of the present invention, the aggregate view module 220 also routes various messages, notifications, queries, and commands to the appropriate selected calendars 240, 250, 260. In some cases, a message is only routed to the active calendar 240, 250, 260. For example, accessibility messages are sent directly to the active calendar. Thus, screen readers and other accessibility tools may determine what appointments are displayed on the active calendar only. As described above, the user may select another displayed calendar 240, 250, 260 as the active calendar as desired. Other types of messages may be sent to all displayed calendars. For example, as described above, if global display settings changes, such as displayed fonts, display sizes, and other formatting information including system colors are changed, the aggregate view module 220 is notified and in turn directs all displayed calendars 240, 250, 260 to make required displayed changes.
FIG. 4 is a computer screen display illustrating selection of other shared calendars for display in a common view of shared calendars. As described above with reference to FIG. 3 an other calendars selection control 340 is provided in the navigation pane 310. In addition to the display of previously selected other calendars in the control 340, an other calendars search control 410 may be provided in the control 340. As shown in FIG. 4, the search control 410 allows a user to enter the name of a friend or associate whose calendar information the user wishes to display in the common view of shared calendars. A drop down contacts list 420 may also be provided to allow the user to parse a list of available calendar data for selection by the user. Once the user has selected an additional calendar for display by the user, a selection control for that user may be subsequently displayed as illustrated in FIG. 3. Likewise, the user may delete a previously utilized calendar selection control from the control 340 so that the selection control no longer appears in the control 340 for selection by the user.
FIG. 5 is a computer screen display showing an actions menu of actions that may be applied to selected dates or times in a given electronic calendar. According to embodiments of the present invention, the user may advantageously view the calendaring data of all selected displayed calendars simultaneously. For example, if the user is interested in requesting a meeting with two of the users colleagues, the user may select each of the colleague's calendars 250, 260 for display next to the user's calendar 240, as illustrated in FIG. 3. The user may then select an actions menu 510 as illustrated in FIG. 5 to select a variety of calendaring actions including a new meeting request action 520. According to embodiment of the present invention, each of the selected shared calendar owner's names are populated in a control 530 to allow the user to readily select the names associated with each of the selected calendars for the desired action such as the new meeting request action 520. If the user selects a name from the control 530, the calendaring application 200 will open a meeting request form prepopulated with the name of the user and the person selected from the control 530. If the user selects “All,” a meeting request form may be created prepopulated with the users name and with the names associated with all selected shared calendars. It should be appreciated that the user may view the calendaring data of each selected calendar, but the user may not write data to the selected other calendars, unless the user has permission to write to the selected calendar.
FIG. 6 is a computer screen display of a print function dialog according to an embodiment of the present invention. According to embodiment of the present invention, a drop down menu such as the “Print this calendar” drop down menu 620 may be provided to allow the user to select for printing any of the selected shared calendars presently displayed by the user.
FIGS. 7, 8 and 9 are flow diagrams showing an illustrative routine for creating and displaying a common view of shared electronic calendars. The method 700 begins at start block 702 and proceeds to block 704 where a user opens a calendaring application 200, as described above. At block 706 the user selects a particular view for opening, such as a calendar view, contacts view, and the like. At block 710, the application frame module 210 controls the display of the view selected by the user. At block 712 a determination is made as to whether the view selected by the user is a calendar view. If the view selected by the user is a non-calendar view, such as a contacts view 230, the method proceeds to block 716 and the selected view is displayed, and the method ends at block 790. If a calendar view is selected by the user, the method proceeds to block 720 and the calendar view is displayed as controlled by the frame module 210.
At block 724, the user selects an additional calendar 250, 260 for display along with the user's own calendar 240. At block 728, FIG. 8, the frame module 210 calls on the aggregate view module 220 to control the display of the plurality of selected calendar views. At block 730, the aggregate view module calls the user's calendar and all selected additional calendars. It should be appreciated, that the user may select for view other calendars, but not select the user's own calendar. That is, it is not necessary according to embodiments of the present invention that the user must first select his or her own calendar followed by the selection of other calendars. Any combination of selected calendars may be displayed according to embodiments of the present invention if the user has permission to display calendaring data associated with the selected calendars.
At block 734, the aggregate view module provides each selected calendar view the controlling view data object. As should be understood by those skilled in the art, the controlling view data object includes the view mode, and other display settings of a parent or first selected calendar. That is, if the first selected calendar is the user's own calendar or if the first selected calendar is from the other calendars control, the view data object for the first selected or parent calendar is provided to each additional selected calendar so that each additional selected calendar will be displayed in a common view mode and common display settings as the first displayed calendar. According to embodiments of the present invention, once a view data object is established for all displayed calendars, that view data object is maintained for displayed calendars even if the first selected or parent calendar is later deleted from display. Thus, whether a displayed calendar is deleted or whether an additional calendar is displayed, the view data object of the first selected calendar is passed to all other selected calendars by the aggregate view module to control display of other selected calendars.
At block 738, the aggregate view module 220 determines a display location for each calendar view. At block 744, the aggregate view module determines a size for each calendar view. For example, the first selected calendar view may require a larger size than subsequent calendar views if the first calendar view requires additional space for a time bar 350. The remaining available space is divided by the aggregate view module between other selected calendars so that each selected calendar including the first selected or parent calendar appears to take an equal amount of display space in the frame 215.
At block 748 the aggregate view module determines the need for and coordinates the use of a time bar a scroll bar. That is, if the view mode for each of the selected displayed calendars requires the use of a time bar, such as is necessary with a daily or hourly view mode, a time bar 350 is called by the aggregate view module. At block 752, the aggregate view module determines the view mode, a date range and time range for the active or selected calendar. At block 758, the aggregate view module directs each selected calendar view to display in the window or frame 215 according to the view data objects, view mode, date range, and time range of the active calendar.
At block 762, the aggregate view module hosts and directs the display of other user interface components of the frame or window 215, including the navigation pane 310 and the tool bar 380. At block 766, FIG. 10, the user may select any displayed calendar to establish the selected displayed calendar as the active calendar, and the user may perform an action in the selected calendar. At block 770, the active calendar view communicates the selected action to the aggregate view module 220. At block 774, the aggregate view module 220 directs any required display changes caused by the user's actions in the active calendar to be made in all other selected displayed calendars. The method ends at block 790.
As described herein, embodiments of the present invention provide methods and systems for simultaneously displaying a plurality of shared electronic calendars in a single application window or frame where each displayed calendar is displayed in a common view mode in side-by-side orientation relative to each other. It will be apparent to those skilled in the art that various modifications or variations may be made in the present invention without departing from the scope or spirit of the invention. Other embodiments of the invention will be apparent to those skilled in the art from consideration of the specification and practice of the invention disclosed herein.
