FIELD OF INVENTION
[0002] The present invention is related generally to a user
interface for a personal digital assistant device.
DESCRIPTION OF RELATED ART
[0003] Carrying a personal digital assistant (PDA) around is very
convenient for tasks such as taking notes at a meeting or lecture,
scheduling appointments, looking up addresses, and for performing a
whole host of other functions. However, one function not easily
performed with a PDA is that of telecommunications. A typical
cellular telephone, meanwhile, offers a range of features, from
speed dial to speakerphone to caller-ID, phonebook, etc. In order
to have the functionality of a cellular telephone and the
functionality of a PDA, consumers have generally had to choose from
a selection of largely unsatisfactory options. The most common
option is to carry both a PDA and cell phone. This is undesirable,
however, because of the obvious impractical aspects of having to
deal with two separate devices, both in terms of sheer bulk as well
as the inconvenience of switching between units. Simply put, there
are more things to buy, more things to break, and more things to
lose.
[0004] Another option is to purchase an add-on telephone device for
a PDA. While this option is preferable to carrying two devices
around, it still has limitations. For example, an add-on telephone
device adds bulk to and changes the form factor of the PDA. In
addition, since such a PDA must be designed to operate without an
add-on telephone, the degree to which the user interface of the PDA
can be integrated with the user interface of the add-on telephone
is limited. Thus, an add-on solution is of only limited value,
since there is not a true integration between the cellular
telephone device and the PDA, but rather two separate devices at
best coexisting side-by-side.
[0005] Accordingly, what is needed is a system and method for
providing a user interface to a device featuring integrated
functionality of both a PDA and cellular telephone.
SUMMARY
[0006] In accordance with the present invention there is provided a
system and method for using an integrated device featuring
functionality of both a PDA and cellular telephone. Features of the
present invention include a power button offering control of both
the computing and telephony functions of the device; a lid that
turns the device on and off depending on its state, and can also be
used to begin and terminate calls; a jog rocker that activates the
device and is used to select from a variety of menu options;
application buttons that offer direct access to applications stored
on the device, and which can be configured to operate in
conjunction with secondary keys to offer added functionality; an
override-able ringer switch; a keyboard; and an Auto Word
Completion function that verifies and corrects a user's typing in
real time.

DETAILED DESCRIPTION
[0017] In the discussion set forth below, for purposes of
explanation, specific details are set forth in order to provide a
thorough understanding of the invention. It will be appreciated by
those skilled in the art that the present invention may be
practiced without these specific details. In particular, those
skilled in the art will appreciate that the methods described
herein can be implemented in devices, systems and software other
than the examples set forth. In other instances, conventional or
otherwise well-known structures, devices, methods and techniques
are referred to schematically or shown in block diagram form in
order to facilitate description of the present invention.
[0018] The present invention includes steps that may be embodied in
machine-executable software instructions, and includes method steps
that are implemented as a result of one or more processors
executing such instructions. In other embodiments, hardware
elements may be employed in place of, or in combination with,
software instructions to implement the present invention. The
software instructions may be stored in RAM or ROM, or on other
media including removable media.
[0019] The present invention includes a user interface for the
operation of an integrated handheld personal computing device and
wireless communication device. Referring now to FIG. 1, there is
shown an example of such an integrated device 100. As illustrated
in FIG. 1, device 100 includes a base section 102, a lid 104,
application and scroll buttons 106, power button 110, antenna 112,
jog rocker 114, and ringer switch 116, and display 118. In
addition, device 100 includes a keyboard 108. As will be
appreciated by those of skill in the art, the present invention may
exist in a variety of embodiments, including embodiments in which
the integrated device includes more or fewer physical components
than are illustrated in FIG. 1. For example, FIG. 2 illustrates
another device 200 that does not have a keyboard, but instead has a
writeable area 202 enabling input to the device 200 via, for
example, a stylus. For convenience and clarity, device 100 of FIG.
1 serves as the illustration that will be referenced throughout
this specification, but such reference should in no way be
understood to restrict what is disclosed to such an embodiment.
[0020] Device 100 includes an integrated GSM radio (also referred
to as a cellular telephone), and while in alternative embodiments
is of varying sizes and shapes, in one embodiment the device is
designed to fit comfortably in a pocket. While the radio uses the
GSM standard in one embodiment, in alternative embodiments the
radio may use the CDMA standard, or any of a variety of other
well-known wireless standards.
Power Button
[0021] Device 100 has a power button 110, located in one embodiment
on the top face, next to the antenna 112. In one embodiment, the
power button 110 performs the following functions: [0022] A single
press and release of the power 110 button toggles device 100
on/off. [0023] Pressing and holding the power button 110 toggles
the radio on/off. [0024] Double-tapping the power button 110
toggles a backlight on/off. [0025] Triple-tapping the power button
110 inverts the display 118 and insures that the backlight is on.
[0026] A single press of the power button 110 when an incoming call
is ringing silences the ring but does not turn off the device
100.
[0027] Referring now to FIG. 3, there is shown a flowchart of the
operation of the power button functionality starting from a
device-off state. Initially, the device 100 is off and the power
key is pressed 300. If the key is being pressed for the first time
within a given period 302 (e.g., it has not been pressed for at
least the previous half second), the device 100 is switched on 304.
If the power button is held down for longer than a threshold amount
of time, e.g., 1 second 306 then the radio is toggled on or off
308. If the power button is held down for less than the threshold
amount 306, then upon release a countdown of predetermined length,
e.g., 1/2 second, is begun 310. If the power button is pressed 312
during the countdown, then the backlight is toggled on or off 314.
If the cycle is repeated and the power button is pressed for a
third time during the countdown 312, then the display 118 is
inverted 316, and the backlight is preferably turned on if it is
not already on. If the power button is not pressed 312 during the
countdown, then no additional actions take place as a result of the
power button press. After the display is inverted in step 316, the
countdown is once again begun 318. However, if the power button is
pressed during this or subsequent countdowns 320, the display is
again inverted at step 316. This countdown cycle continues until
the power button is not pressed during the countdown 320.
[0028] Referring now to FIG. 4, there is shown a flowchart of the
operation of the power button functionality starting from a
device-on state. Initially, the device is on, and the power key is
pressed 400. If the power key is being pressed for the first time
402 (e.g., it has not been pressed for at least the previous half
second), no action is initially taken. If the power button is held
down for longer than a threshold amount of time, e.g., 1 second 404
then the radio is toggled on or off 406. If the power button is
held down for less than the threshold amount 404, then upon release
a countdown of predetermined length, e.g., 1/2 second, is begun
408. If the power button is not pressed 410 during the countdown,
then the device is turned off 416. If the power button is pressed
410 during the countdown, then the backlight is toggled on or off
412. If the cycle is repeated and the power button is pressed for a
third time during the countdown, then the display is inverted 414,
and the backlight is turned on if not already on. After the display
is inverted 414, another countdown is begun 416. If the power
button is pressed again 418 during the countdown, then the display
is once again inverted 414, and countdown 416 restarted. This
continues until the countdown expires without the power button
being pressed 418.
[0029] In addition, in one embodiment pressing the power button 110
when there is an incoming call silences the ring or vibrate.
Further, if a call is in progress, pressing the power button turns
off the device 100 but does not terminate the call. Finally, if the
device is off when a call comes in, the device is turned on, and
the backlight is illuminated, which helps to locate the device 100,
e.g., in a poorly-lit room.
Lid
[0030] Referring again to FIG. 1, there is shown a view of device
100, having a lid 104 attached to base 102. In FIG. 1, lid 104 is
connected to base 102 via a hinge or other mechanism that allows
lid 104 to open and close. Note that the lid 104 may be connected
to base 102 in any of a variety of ways while still including
features described herein. The particular embodiment of FIG. 1 is
therefore meant to illustrate only one of many possible
configurations.
[0031] In one embodiment, lid 104 features a hardware switch for
lid open and lid close detection, and may additionally include an
integrated speaker for flip phone-like functionality. When closed,
in one embodiment, lid 104 covers all of base 102 except for
application and scroll buttons 106. In one embodiment, lid 104 also
includes a transparent window for viewing the display 118 of device
100 while the lid 104 is closed.
[0032] The effect of opening and closing the lid 104 varies
according to the state of device 100 at the time the lid 104 is
opened or closed. In one embodiment, and referring now to FIG. 5,
opening and closing the lid 104 has the following effect:
[0033] If the device is off, opening the lid turns on the device
100, and launches 502 a predetermined application. In one
embodiment, the predetermined application is a speed dial view of a
telephone application, however in other embodiments the application
can be any application on the device 100, assignable by the user in
one embodiment via a preferences control panel-type application. If
the device is off, closing the lid has no effect 504.
[0034] If the device is on, then it is in one of three states:
either a call is in progress, a call is incoming, or there is no
call activity.
[0035] If a call is incoming, then an incoming call notification is
given to the user. An illustration of such a notification is shown
in FIG. 8. It will be appreciated that a user may be in the process
of opening the lid when a call comes in. In such a situation, the
user may not want to actually take the incoming call. For that
reason, if the lid is opened within, in one embodiment, one second
of the incoming call notification, no action is taken 506 (although
the user can still answer the call in other ways, e.g., by tapping
a dialog box 802 on the display of device 100). In other
embodiments, the time maybe shorter or longer than one second. If
the lid is opened more than one second after the initial incoming
call notification, then the call is answered 508. Note also that in
one embodiment a user can choose to accept or ignore any incoming
telephone call by selecting the answer 802 or ignore 804 options
presented in a popup dialog box.
[0036] Similarly, if the user is in the process of closing the lid
when a call comes in, it is desirable to assume that the lid is
being closed not in response to the incoming call, but rather by
coincidence. Thus, if the lid is closed within an initial time,
e.g., one second, of the first notification of an incoming call, no
action is taken 510. After this initial period, if the lid is
closed, then in one embodiment the ring is silenced, the call is
ignored, and the device is turned off 512.
[0037] During an active call, the lid is open in a preferred
embodiment, unless a headset is plugged in. If a call is in
progress and the headset is being used, then opening the lid has no
effect on the call 514. If the lid is closed while a headset call
is in progress, the device is turned off, but the call is not
disconnected 516. If a telephone call is in progress without using
a headset, then closing the lid hangs up the telephone, in one
embodiment after displaying a warning message confirming that the
call is about to be disconnected, and turns the device off 518.
During the confirmation warning message, the user has the
opportunity to tell the device not to disconnect the call, e.g., by
pressing the scroll-up button. In alternative embodiments, the call
is disconnected as soon as the lid is closed.
[0038] If a telephone call is not in progress, then in one
embodiment, opening the lid when the device is already on has no
effect 520. That is, even if there is an application assigned to be
launched upon the opening of the lid, when the power is already on,
opening the lid does not launch the assigned application, but
rather has no effect on what application is currently executing.
Also, in one embodiment, if a call is not in progress, closing the
lid turns the device off 522.
[0039] In addition, in one embodiment keyboard 108 is deactivated
when the lid 104 is closed, whether the device 100 is on or off.
This guards against inadvertent input to the device when pressure
is applied to the lid, e.g., if the device is carried in a pocket,
or if something heavy is placed on top of the device. In
alternative embodiments, the keyboard 108 remains active at all
times regardless of lid position. In one embodiment, application
and scroll buttons 106 remain active even when the lid 104 is
closed. This allows the scroll buttons to be used to respond to
dialog boxes that may be presented to the user when the lid is
closed. For example, if an alarm goes off, the user can dismiss the
alarm by pressing a scroll button, instead of having to open the
lid to tap the display 118 or press a button on the keyboard
108.
Jog Rocker
[0040] Device 100 includes a jog rocker 114 such as is pictured in
FIG. 1. A jog rocker in one embodiment allows four input actions:
up, down, press in, and press and hold.
[0041] While individual applications provide specific responses to
input from jog rocker 114, in one embodiment pressing the jog
rocker 114 when device 100 is turned off wakes device 100 up and
launches a predefined application, such as the phone application in
one embodiment.
[0042] In one embodiment, this behavior is executed on jog rocker
114 press, not release, so one embodiment, this behavior is
executed on jog rocker 114 press, not release, so that a press and
hold of the jog rocker 114 wakes the device up, launches the
predefined application on the press, and then executes within the
application whatever that application has specified for a jog
rocker 114 hold on the hold.
[0043] In another embodiment, jog rocker 114 can be used to provide
a scroll-up and scroll-down function similar to that provided by
scroll buttons 106. In one embodiment, this is the default use for
jog rocker 114 when an application does not provide additional
functionality for the jog rocker.
Ringer Switch
[0044] Ringer switch 116 is used in a preferred embodiment to
select whether incoming telephone calls should produce an audible
ringing sound on device 100. In a first position, device 100
produces such a ring tone, which is customizable in one embodiment
using application software stored on device 100. In a second
position, device 100 does not produce a ring tone for an incoming
call. In one embodiment, device 100 is configured to vibrate in
response to an incoming telephone call. The vibrate feature of
device 100 may additionally be activated by applications executing
on device 100, for example even when ringer switch 116 is in the
first position (the audible ring position).
[0045] In one embodiment, when ringer switch 116 is in the second
position, all sounds made by device 100 are muted, and not just the
ring tone. Thus, for example, while a number of applications
executed on device 100, e.g., an alarm, a message alert, etc., may
instruct device 100 to produce a sound, the location of the switch
in the second position will stop device 100 from actually making
the sounds. In yet another embodiment, device 100 allows software
resident on device 100 to override the physical setting of ringer
switch 116. This may be of particular use, for example, if the
ringer switch is in the first position while a call is in progress
and it is undesirable to have sounds from device 100 interfering
with the call in an annoying fashion.
Application Buttons
[0046] A device such as device 100 typically has one or more
application and scroll buttons 106 located physically on the
device, providing direct access to applications associated with the
buttons, as well as up-down and left-right scroll functionality.
Using a keyboard 108 of device 100, different applications are
assignable to the application buttons 106 being pressed in
combination with a modifier key. In one embodiment, an "option" key
is the modifier key for these key combinations.
[0047] In one embodiment, the following applications are mapped to
option and ("+") application button combinations:
[0048] Option+Phone Application button maps to Memo Pad.
[0049] Option+Calendar Application button maps to To-Do.
[0050] Option+Internet Browser Application button maps to
CityTime.
[0051] Option+Messaging Application button maps to the
calculator.
[0052] In one embodiment, the Option+Application button key
combination works both in series and in parallel. For example,
pressing and releasing the Option button (a serial combination),
then pressing an application button 106 launches the application
that is mapped to that application button's option modification.
Similarly, pressing and holding the Option button while pressing
the application button 106 (a parallel combination) also launches
that application button's option modification.
[0053] If the option modification times out before the application
button 106 is pressed, then the functionality is the same as if
only the application button had been pressed.
[0054] Pressing and holding Option, and then pressing an
application button 106 while Option is still held down also
launches the application that is mapped to that applications
button's option modification. What occurs if the user continues to
hold the application button in is controlled on an
application-by-application basis.
[0055] In one embodiment, the following application buttons 106 and
combinations are mappable:
[0056] a Phone Application button.
[0057] a Calendar Application button.
[0058] an Internet Browser Application button.
[0059] a Messaging Application button.
[0060] In alternative embodiments, the following combinations are
also mappable: [0061] Option+Calendar Application button. [0062]
Option+Phone Application button. [0063] Option+Internet Browser
Application button. [0064] Option+Messaging Application button.
Keyboard
[0065] In one embodiment, keyboard 108 includes the following
keys:
[0066] a-z (26 keys)
[0067] . (period)
[0068] Symbol key
[0069] Space
[0070] Return
[0071] Backspace
[0072] Shift key
[0073] Option key
[0074] Menu key.
[0075] FIG. 6a illustrates one embodiment of a keyboard 108 layout.
In FIG. 6A, the bottom label of each key indicates its normal
character, while the top left label indicates its shift key
character, and the top right label indicates its option key
character.
[0076] FIG. 6b illustrations just the number/punctuation keys
extracted from FIG. 6a.
[0077] In an unmodified state, the keys produce the main character
printed on them. In one embodiment, there is no on
screen-modification state indicator for the unmodified keyboard
state. In Shift state, the keys produce a capital version of the
main character printed on them, as illustrated in FIG. 6a.
[0078] In Option state, the keys produce the alternate character
illustrated in FIG. 6b.
[0079] In one embodiment, pressing the Option key once puts device
100 in Option state. Pressing Option in Option state puts the
device in Option Lock state. Pressing Option in Option Lock state
clears the state. Option state is canceled upon the entry of the
Option-modified character. Option Lock state is not canceled upon
the entry of the Option-modified character, hence the Lock-ness.
Option state can be canceled without entering a character by
pressing the Option key twice (once for lock, the second for clear)
or pressing backspace. Note that in one embodiment, backspace
cancels Option state, but not Option Lock state.
[0080] Referring now to FIG. 7a, in one embodiment, an on-screen
modification state indicator 702 for Option state, which indicates
to the user that the Option key has been pressed, is an oval tilted
to have the same appearance as the shape of the Option key
itself.
[0081] Referring now to FIG. 7b, the on-screen modification state
indicator 704 for Option Lock state is similar to the Option state
indicator except with a "bottom bar".
[0082] Holding down a key for a prolonged period causes the key to
repeat. In one embodiment, all text entry has the same repeat rate,
i.e., holding down the j produces j's at the same rate as holding
down shift+j produces J's and option+j produces 5's. The Option and
Shift keys both "time out" if additional input is not received
within a prescribed period of time, e.g., 3 seconds in one
embodiment. Note that in one embodiment the Option Lock and Shift
Lock states do not time out.
[0083] In addition, in a preferred embodiment, when the currently
executing application on device 100 changes from a first
application to a second application, the Shift state is cleared to
avoid unintended Shifted input into the second application.
Auto Word Completion
[0084] In order to provide a fast and easy way to enter awkward or
often-misspelled text, device 100 includes a word
auto-completion/correction system that in one embodiment checks
every word that a user enters against a database of common
misspellings and convenient abbreviations and replaces the entered
word with a preset correct or complete version of the word. For
example, if a user enters `believe`, it will automatically be
replaced with `believe`. If a user enters `im`, it will be replaced
with `I'm`.
[0085] In one embodiment, Word Completion executes whenever a user
enters any character that signals that they are finished typing the
previous word, e.g.:
[0086] Space
[0087] Any punctuation
[0088] Tab
[0089] Return
[0090] Next or Previous Field.
[0091] For instance, when a user types b,e,l,e,i,v,e the word
`beleive` is still displayed. If the user then enters a space (or
any of the characters listed above) then `beleive` is replace by
`believe`. Typing backspace once will erase the space (or tab, new
line, etc.) that invoked the Word Completion. Typing backspace a
second time will undo the word completion without deleting the last
character of the word. At this point, typing any of the characters
that usually invoke Word Completion will not invoke it again.
[0092] If the replacement word in the database is not capitalized,
then the capitalization of the word to be replaced is maintained.
For instance, there is an entry in the Word Completion database
that has the wrong word "feild" marked to be replaced with "field"
so:
[0093] feild becomes field.
[0094] Feild becomes Field.
[0095] If the replacement word in the database is capitalized, then
the resulting word is capitalized no matter what the capitalization
of the word to be replaced was. For instance, there is an entry in
the Word Completion database that has the wrong word "im" marked to
be replaced with "I'm" so:
[0096] im becomes I'm.
[0097] Im becomes I'm.
[0098] FIGS. 9a-9c show a number of example input character strings
and their corresponding replacement character strings. In some
aspects, the input character string may be a misspelled word, and
the corresponding replacement character string may be a correctly
spelled version of the input character string. For example, when a
user enters the input character string "acn", the mobile computing
device 100 may replace the input character string with the
replacement character string "can". In other aspects, the input
character string may be an abbreviation, and the corresponding
replacement character string may be a completed version of the
input character string. For example, when a user enters the input
character string "sec", the mobile computing device 100 may replace
the input character string with the replacement character string
"second".
[0099] FIG. 10 shows a number of example input character strings
and their corresponding replacement emoticons. For example, when a
user enters the input character string ":-)", the mobile computing
device 100 may replace the input character string with the
smiley-face emoticon.
Keyboard Navigation and Commands
[0100] In one embodiment, device 100 switches off or "sleeps" in
order to conserve power after a predefined period of time. In such
circumstance, pressing a key on the keyboard 108 wakes the device
back up, i.e., restoring the device to a power on state in the same
condition that it was in prior to going to sleep. In other
embodiments, waking the device 100 up is equivalent to a power on
command, which starts the device with a predefined initial
application. Note that the keys which will wake the device up may
be predetermined, or may be changeable by the user.
[0101] In one embodiment, some navigational activities of device
100 are keyboard enabled. Buttons such as "OK," "Done," and
"Cancel" are mapped to certain keys and key combinations. Common
actions, which may also be on-screen buttons like "New" and
"Details . . . ," are frequently included as menu items. These menu
items have menu button+letter combinations assigned to them so that
they may be executed easily from the keyboard 108.
[0102] In one embodiment, menus on device 100 are navigable via a
menu key and menu mode. Pressing and releasing a dedicated hardware
menu key on keyboard 108 displays a first pull-down menu of the
current view. Pressing and releasing the menu key a second time
dismisses the menu.
[0103] While the menu is being displayed, in one embodiment the
user can navigate the menus and execute menu items with the
following actions: [0104] Scroll Up displays the next menu list to
the right. [0105] Scroll Up from the last menu list scrolls back to
the first. [0106] Holding Scroll Up repeats this action at the
normal repeat rate. [0107] Scroll Down moves a highlight down
through the current displayed list of menu items. [0108] If there
is no highlighted item, such as when the menu list is first
displayed, then the first press of Scroll Down highlights the first
menu item. [0109] Scroll Down from the last menu item in the list
scrolls back to the first item in the same list. [0110] Holding
Scroll Down repeats this action at the normal repeat rate. [0111]
Space executes the highlighted menu item on press. [0112] Return
also executes the highlighted menu item on press. [0113] Backspace
dismisses the menu. [0114] At any time when any menu is displayed,
pressing any of the short cut letters executes the corresponding
menu item, even if that menu item is in a menu list that is not
currently displayed. [0115] Typing any character that is not
detailed above or a short cut letter plays an error beep.
[0116] At any time, whether or not a menu is displayed, pressing
and holding the menu key and pressing a one of the shortcut letters
executes the corresponding menu item, in one embodiment, without
the menu being drawn on the screen. Pressing and releasing the menu
key and then pressing the shortcut letter will display the menu,
however, in one embodiment.
[0117] Any menu that is being displayed is dismissed whenever a
menu item is executed. Shift Lock and Option Lock are ignored when
entering short cut letters. It is possible, however, to enter an
option character as a short cut character in parallel: [0118] User
presses the menu button to enter menu mode. [0119] User presses and
holds Option. [0120] User presses x for instance. [0121] The menu
item with the short cut character? would get executed, because the
question mark (?) is formed by pressing Option-x. [0122] Pressing
and releasing Option and then pressing x would execute the menu
item with the short cut letter x.
[0123] Menu mode itself will not clear the modification state, but
the execution of a menu item may clear the modifications state
depending on what that menu item does.
[0124] User starts in Option Lock.
[0125] User presses the menu button.
[0126] User presses the menu button again to dismiss the menu.
[0127] The user should still be in Option Lock.
[0128] Thus, when buttons containing certain text are on the
screen, certain keys or key combinations can be pressed that will
execute the buttons as if they were pressed on the screen.
[0129] The buttons that are mapped to the keyboard in one
embodiment are: [0130] OK [0131] Done [0132] Cancel [0133] Yes
[0134] No [0135] Next [0136] Previous.
[0137] The following four keys/key combinations are used for
mapping to certain common on-screen buttons in one embodiment:
[0138] Return
[0139] Backspace
[0140] Option+Return
[0141] Option+Backspace [0142] Option+Return and Option+Backspace
will work on in parallel.
[0143] Globally, in one embodiment:
[0144] Option+Return executes: [0145] OK [0146] Done [0147] Yes
[0148] Next [0149] Send [0150] Accept
[0151] Option+Backspace executes: [0152] Cancel [0153] No [0154]
Previous [0155] Back [0156] Reject
[0157] In one embodiment, if there is no opportunity for text entry
on a particular screen, then the holding down of the Option key may
be unnecessary. Thus, for example, within the context of alert
dialogs:
[0158] Return executes: [0159] OK [0160] Done [0161] Yes [0162]
Next [0163] Send [0164] Accept
[0165] Backspace executes: [0166] Cancel [0167] No [0168] Previous
[0169] Back [0170] Reject
[0171] Return and Backspace do not map to buttons in other contexts
in one embodiment, since in other contexts there will likely be
text areas in which Return and Backspace benefit from their normal
functionality.
[0172] In addition, in one embodiment the mappings described above
also apply to non-English based applications. For example,
Option+Return is mapped to "Oui" in a French language application.
This allows a user to execute a foreign-language application on
device 100 while providing similar functionality to an
English-language application.
[0173] The foregoing discloses exemplary methods and embodiments of
the present invention. It will be understood that the invention may
be embodied in other forms and variations without departing from
the spirit or scope of the invention. Accordingly, this disclosure
of the present invention is illustrative, but not limiting, of the
invention, the scope of which is defined by the following
claims.
