RELATED APPLICATION INFORMATION
[0001] This application is a continuation application of U.S.
patent application Ser. No. 12/128,553, filed May 28, 2008,
entitled "MECHANISM FOR DISPLAYING PAGINATED CONTENT ON ELECTRONIC
DISPLAY DEVICES," which is a continuation application of U.S.
patent application Ser. No. 11/112,183, filed Apr. 22, 2005,
entitled "COMPUTING DEVICE FOR DISPLAYING CONTENT IN PAGES OR IN
SEQUENCE," now U.S. Pat. No. 7,394,452, which is a continuation of
U.S. patent application Ser. No. 09/854,316, filed May 11, 2001,
now U.S. Pat. No. 6,943,773, entitled "PAGE FLICKING MECHANISM FOR
ELECTRONIC DISPLAY DEVICES THAT PAGINATE CONTENT"; all of the
aforementioned priority applications being hereby incorporated by
reference in their entirety.
FIELD OF THE INVENTION
[0002] The present invention relates to displays for computer
devices. In particular, the present invention pertains to a page
flicking mechanism for a display of a computer device.
BACKGROUND OF THE INVENTION
[0003] Flexible display technology is an advancing area in the
field of computing devices. Many applications are being planned and
designed to incorporate flexible display technology. Currently,
products described as "electronic paper" or "e-paper" are being
integrated with computing tablets, handheld computers and other
computing devices. Consumer applications for flexible display
technology includes electronic books and magazines.
[0004] Electronic book applications are currently popular for
computing devices such as handheld computers and laptops. In
general, electronic books are documents formatted to be paginated
on the display of the computing device. A user can scroll the
display to view different portions of the same page. The user can
also select to view other pages. To make selections for other
pages, the user typically has to select a user-interactive feature,
such as an icon on the display, or a mechanical button. The page
that appears after the user's selection coincides with a page
stored as the next or adjacent page to the existing page appearing
on the display. If the user wishes to scroll through many pages,
the user is required to make repeated entries into the
user-interactive feature, or perhaps make one sustained entry.
SUMMARY OF THE INVENTION
[0005] A computing device is provided that is capable of displaying
paginated content on a display. A deflective input mechanism is
incorporated with the computing device. A user can deflect the
input mechanism to signal a page flick. A processor of the
computing device configures the pagination appearing on the display
in response to the deflection of the input mechanism.
[0006] The processor may cause the display to present several pages
of the content in succession as the response to the deflection of
the input mechanism. The pages appearing on the display may also
skip with reference to a predetermined order of each page in the
paginated content.
[0007] The deflective input mechanism may be integrated or
otherwise include the display of the computing device. In one
embodiment, the display is formed of flexible "electronic paper",
to enable bending or flexing by the user. A sensor of the input
mechanism may measure a deflection of the display in order to
signal the processor a deflection value. To accommodate the
display, other components of the computing device, such as the PCB,
the digitizer and the housing, may also be deflectable.
[0008] Another embodiment may include a deflective sensor device
that is coupleable to one of the flexible components of the
computing device. The sensor device may be integrated with a
deflective housing or PCB to measure the deflection caused by the
user.

DETAILED DESCRIPTION OF THE INVENTION
[0023] Embodiments of the invention describe a page flicking
mechanism for a computing device that displays paginated content.
In the following description, for the purposes of explanation,
numerous specific details are set forth in order to provide a
thorough understanding of the present invention. It will be
apparent, however, that the present invention may be practiced
without these specific details. In other instances, well-known
structures and devices are shown in block diagram form in order to
avoid unnecessarily obscuring the present invention.
[0024] A. Overview
[0025] Embodiments of the invention provide a page flicking
mechanism for a computing device that displays paginated content.
In an embodiment, a display of the computing device includes a
plurality of discrete elements, such as pixels. A memory is used to
store a data collection. The data collection is arranged or
otherwise identifiable as a plurality of pages. The pages of the
data collection are arranged in a pre-selected order, and are each
individually presentable on the display. The computing device
includes a processor that is configured to retrieve the pages from
the memory. The processor is also configured to signal each of the
pages for presentation on the display. A sensor device is coupled
to the processor. The sensor device is deflectable to signal the
processor a deflection value when deflected. The deflection value
causes the processor to sequentially present all or some of the
multiple pages, in a sequential and individual manner.
[0026] A display may include any device that responds to electrical
signals to output an image. An image presented on the display may
be a partial, complete, or approximate rendering of data stored for
that page.
[0027] When multiple pages are sequentially presented, portions of
the display render an image from each of the multiple pages in a
sequence, so that one page may follow another on a portion of the
display. It is possible that an area of the display presents
portions of multiple pages concurrently and in a sequential manner.
For example, groups of discrete elements of the display may be
assigned values from one of the multiple pages, and then a next,
while another group of discrete elements are static.
[0028] As used herein, reference to deflection means any type of
bending, deformation or movement by a structure that noticeably
alters its shape. In one embodiment, deflection refers to a
cantilevering movement of one end of a structure relative to
another.
[0029] FIG. 1 illustrates a computing device 100 equipped with a
page flicking mechanism, under an embodiment of the invention. The
computing device 100 includes a flexing or deflective display 20
that presents paginated information. The display 20 is connected to
a frame 25. In one embodiment, both display 20 and frame 25 are
bendable along one or more axes of the computer device 100.
[0030] The display 20 may be a form of electronic paper. Electronic
paper refers to a flexible display, used for applications such as
electronic books. An example of electronic paper for use with
embodiments of the invention includes conductive plastic substrates
combined with organic transistors, manufactured jointly by E Ink
Corp. and Lucent Technologies (see Electronic Paper Writes New
Chapter for Displays; Brown, C.; EETimes.com, Nov. 30, 2000; hereby
incorporated by reference). Another example of electronic paper
includes gyricon substrates, manufactured by Xerox.
[0031] As will be described in greater detail, the display 20 can
be deflected to enable a user to enter an input. The deflection
entered by the user causes the pagination being presented on the
display 20 to be altered. Specifically, an embodiment provides that
a region 22 of display 20 sequentially presents other pages based
on the deflection of display 20. The display region 22 may be
centrally disposed on display 20 where the deflection is least
impairing to the user. The sequential presentation of the pages on
display region 22 provides the appearance of page flicking.
[0032] The computing device 100 may be configured to measure the
magnitude of the deflection and to correlate the magnitude with a
characteristic of the page flicking. A larger magnitude flexing of
display 20 may signal rapid page flicking, and possible skipping of
intermediate pages. A smaller magnitude flexing of display 20 may
correlate to a slower page turn, without any skipping of pages. For
example, a large deflection of display 20 may result in display
region 22 displaying pages 1, 5, 10, 15 and 20 in one time
interval. A small deflection may cause display region 22 to display
pages 1, 2 and 3 in a longer time interval.
[0033] Other portions of display 20 outside of display region 22
may display content other than the pages being flicked through. For
example, the presentation on the other portions of display 20 may
be frozen on a current page, or blurred to save processing
resources.
[0034] FIG. 2 illustrates another embodiment in which computing
device 100 separates display 20 from a deflectable portion 30 (FIG.
30). The deflectable portion 20 may be integrated with a sensor
(see e.g. 130, FIG. 4) to detect deflection caused by the user of
the computing device 100. When the deflectable portion 30 is
deflected, the display 20 displays multiple pages in a sequential
manner on display region 22. For such an embodiment, display region
22 may be disposed closer to an edge farthest away from deflectable
portion 30.
[0035] FIG. 3 illustrates an embodiment in which computing device
100 is coupleable to deflectable portion 30. In an embodiment,
deflectable portion 30 can be connected to the side of computing
device 100 through an attachment mechanism 35. The attachment
mechanism 35 may include communication resources for signaling
deflection values to a processor 140 (see FIG. 4) of computing
device 100. Alternatively, a peripheral expansion slot (see e.g.
102
[0036] FIG. 4) may extend communications between a sensor contained
within the deflectable portion 30 and a processor of the computing
device 100.
[0037] B. Hardware Components
[0038] FIG. 4 is a block diagram of computing device 100, including
components for presenting and changing pages on a display. The
computing device 100 includes a processor 140 coupled to a first
memory 144 and a second memory 146. The processor 140 is coupled to
a display driver 122. The processor 140 combines with display
driver 122 to process and signal data for presentation on a display
120. A sensor 130 is coupled to processor 140 via an analog-digital
(AD) converter 132.
[0039] The computing device 100 may include one or more expansion
slots. In an embodiment shown, a first peripheral port 102 enables
one or more types of accessory devices to be connected to processor
140. In addition, computing device 100 may include a wireless
peripheral port 104 that enables information to be communicated to
processor 140 from an external source. The wireless peripheral port
104 forwards incoming communications to an amplifier 106 for
processor 140. A second processor 108 intercepts communications
incoming to and/or outgoing from wireless peripheral port 104 for
purpose of facilitating conversion of data signals between formats
and protocols of wireless communications, and those that can be
processed by processor 140.
[0040] The display 120 cooperates with display driver 122 to
display paginated content such as text-based information. For
example, display 120 may be used to display pages from electronic
books. The paginated content may be primarily in the form of text,
although other information such as images, video clips and
animation, may also be presented on display 120. In an embodiment,
first memory 144 corresponds to non-volatile memory for computing
device 100. The first memory 144 stores a data collection
corresponding to the paginated content. The processor 140 accesses
first memory 144 to retrieve the data. The processor 140 combines
with display driver 122 to present the data in a paginated format
on display 120.
[0041] To present a selected page, processor 140 accesses first
memory 144 for values in the data collection that are assigned to
the selected page. Each selected page of the paginated content is
presentable on display 120 while other pages are cached in second
memory 146. Alternatively, the data collection may be signaled to
processor 140 from a peripheral device, through first peripheral
port 102 or wireless peripheral port 104. Either first memory 144
or second memory 146 may be used to store portions of the data
collection received from the peripheral device. The second memory
146 may be used to buffer or cache the data collection while one or
more of the pages from the data collection is being displayed.
[0042] The sensor 130 is used to detect a deflection entered as
input by a user. The deflection input may be measured as an analog
value that is signaled to processor 140. The deflection input
causes portions of one or more pages from the data collection to be
displayed on at least a portion of display 120. The deflection is
measured by sensor 130 for processor 140. In this way, the user may
deflect a component of computing device 100 to signal an input to
the processor 140. The processor uses a detected value of the input
to present multiple pages on all or portions of display 120 over
the course of a selected time period. As will be further described,
embodiments of the invention allow for sensor 130 to detect
deflection created on sensor 130, display 120, on a printed circuit
board (PCB) of computing device 100, on a housing of computing
device 100, or on a combination of sensor 130 and another component
of computing device 100. The deflection may simulate the bending of
a book or stack of pages, prior to their pages being flicked.
[0043] In an embodiment, the analog value measured by sensor 130
reflects the magnitude of the deflection, as well as other
characteristics such as its duration, or flick speed. To process
the information detected by sensor 130, AD converter 134 is coupled
to receive the analog input from sensor 130. The AD converter 134
converts the analog input into a digital format for processing by
processor 140. The AD converter 134 may also include several
channels to receive other analog inputs or values from other
components. For example, one of the channels 136 may be coupled to
a digitizer 260 (see FIG. 5-7) of computing device 100 to detect
position information of a stylus in contact with display 120.
[0044] FIG. 5 is a top view of computing device 100, illustrating
positioning of a sensor device 230, under an embodiment of the
invention. The sensor device 230 may perform functions as described
with sensor 130 (FIG. 4), but is combined or housed within a
deflectable structure. The sensor device 230 may be combined with
another deflectable component (such as display 120) to correlate
the deflection of the sensor device 230 with deflection of the
other component.
[0045] In an embodiment shown by FIGS. 2 and 3, computing device
100 is a tablet having a length L extending between a top 207 and a
bottom 209. A width W extends between lateral sides 203, 203. A
housing 210 of computing device 100 retains display 120 (FIG. 1),
as well as housing other components. The housing 210 retains a
digitizer 260 in cooperation with display 120. Among other
functionalities provided, digitizer 260 enables input to be entered
onto display 120 through contact. The digitizer 260 detects the
position of the contact and correlates the position contact with an
input. The digitizer 260 may be positioned on top of display 120,
or be overlaid by display 120. For the embodiment shown, digitizer
260 is assumed to be under display 120. In some computing device
100, digitizer 260 may extend beyond display 120 along the top edge
222, bottom edge 224, or one of the lateral edges 226, 228. In
particular, for many types of devices, digitizer 260 may extend
beyond the lateral edges 226, 228 of display 120.
[0046] With reference to FIG. 5, a top segment 217 of housing 210
measures the distance from a top edge 222 of display 220 and a top
207 of computing device 100. A bottom segment 219 of housing 210
measures the distance from a bottom edge 224 of display 220 and a
bottom 209 of computing device 100. A first lateral segment 213 of
housing 210 measures the distance from one of the lateral sides 203
and a lateral edge 226 of display 220. Similarly, a second lateral
segment 215 of housing 210 measures the distance from the other one
of the lateral sides 203 and another lateral edge 228 of display
220.
[0047] In an embodiment, sensor device 230 is positioned within
housing 210 on or adjacent to an exterior surface. For example, a
front panel 212 of housing 210 may provide access to display 220.
The sensor device 230 may be positioned directly underneath front
panel 212. To this end, sensor device 230 is positioned apart from
display 220 and digitizer 260. In one embodiment, sensor device 230
is positioned on top segment 217 of housing 210. To enable sensor
device 230 to measure a deflection, both housing 210 and sensor
device 230 may be configured to bend or cantilever. The display 220
and digitizer 260 may be similarly configured. For sensor device
230 such as described with FIGS. 4 and 5, the direction of bending
would cantilever top segment 217 into the paper.
[0048] FIG. 6 illustrates another embodiment in which sensor device
230 is positioned lengthwise within housing 210 of computing device
100, so as to extend between top 207 and bottom 209. Since
digitizer 260 may extend towards lateral side 203, sensor device
230 may be positioned underneath both display 220 and digitizer
260. The first lateral segment 213 may overlay at least a portion
of sensor device 230 and digitizer 260. The sensor device 230 is
deflective to measure a deflection entered by the user. To
accommodate the deflection, housing 210, display 220, and digitizer
260 may deflect with sensor device 230, so that lateral side 203 of
computing device 100 nearest sensor device 230 deflects into the
paper.
[0049] With reference to FIGS. 5 and 6, display 220 may be
described with reference to a deflected region 225. The deflected
region 225 may coincide to a portion of display 220 where
presentation of the data collection is altered as a result of the
deflection created by the user. The deflected region 225 may also
coincide with a region of display 220 that is the boundary of
physical deflection on display 220. The deflected region 225 may be
positioned center or off-center to best suit positioning of sensor
device 230. For example, if one of the lateral sides 203 is
deflectable, deflected region 225 may be off-center to accommodate
one region of display 220 being deflected. Furthermore, variations
to pages being presented from the data collection may be provided
on a boundary provided within deflected region 225. For example,
when lateral side 203 is bent, pages may appear to be flicked to
the left of deflected region 225. In addition, display 220 may
include multiple deflectable regions 225.
[0050] FIG. 7 is a cross-sectional view of computing device 100,
cut along lines U-U of FIG. 6. FIG. 7 illustrates sensor device 230
in relation to other components of computing device 100, under an
embodiment of the invention. The display 220 is coupled over
digitizer 260. The combination of display 220 and digitizer 260 are
coupled to housing 210, and positioned over a PCB 270. The PCB 270
may provide components such as processor 140, first memory 144,
second memory 146 and other components described with FIG. 4. While
display 220 is shown to be overlaid on digitizer 260, other
embodiments may provide other configurations. In particular,
digitizer 260 may be mounted over display 220, or integrated as one
unit with display 220. Still further, computing device 100 may not
have digitizer 260, since that component is typically used to
enable touch-sensitive entries onto display 220.
[0051] In a direction shown by axis Z, sensor device 230 is
positioned just underneath digitizer 260. This may correspond to
position A. In another embodiment, sensor device 230 may be
positioned immediately adjacent (either above or below) to PCB 270.
This may correspond to position B or C. The positions A, B, and C
are possible for a configuration such as shown with FIG. 6. For a
configuration such as shown with FIG. 5, sensor device 230 may be
positioned adjacent display 220, such as provided by position D
(extending into the paper). In position D, sensor device 230 may be
proximate to or adjacent to the front panel 212 of the housing 210,
as digitizer 260 does not extend above display 220.
[0052] In an embodiment, sensor device 230 measures its own
deflection. Therefore, sensor device 230 may be deflectable, and
positioned within computing device 100 to enable its deflection by
a user. To this end, portions or all of housing 210 may be flexible
to bend in an area coinciding with the position of sensor device
230. The display 220 may be bendable to accommodate sensor device
230 being positioned underneath display 220. The digitizer 260 may
be similarly constructed if used in cooperation with display 220.
The PCB 270 may be flexible to accommodate bending of sensor device
230 in position B, C and possible A. Alternatively, PCB 270 may be
shortened or otherwise to be away from a region of computing device
100 that deflects. If sensor device 230 is positioned at D,
digitizer 260 and PCB 270 may each be shortened. In this way, the
housing 210, and possible display 220, may be the flexible
components of computing device 100 that bend for sensor device 230
to enable deflection to be entered as an input.
[0053] B. Sensor Device
[0054] FIGS. 8-9 illustrate a deflectable sensor device 230 for use
with computing device 100, under an embodiment of the invention.
FIG. 8 is illustrative of a partial cross-section taken along lines
W-W of FIG. 6. In an embodiment shown, display 120 is mounted over
digitizer 260, adjacent to first lateral segment 213 of housing
210. The digitizer 260 extends beyond a boundary of display 120
towards lateral side 203 of housing 210. The sensor device 230 is
positioned immediately underneath digitizer 260. The sensor device
230 may include one or more conductive elements extending a width
of the sensor device 230. To accommodate deflection, display 120,
digitizer 260 and sensor device 230 may all be deflectable for the
user. The flexure of the deflecting components may be designed to
simulate the feel of a book bending to flick pages.
[0055] In an embodiment, sensor device 230 includes multiple
conductive elements 232 that are intertwined or spaced in
cooperation to provide an electrical property measuring a distance
between them. The conductive elements 232 may be static and spaced
in a default position when sensor device 230 is not deflected. In
an embodiment, conductive elements 232 of sensor device 230 are
extended perpendicular to the length of sensor device 230. Other
embodiments may provide conductive elements 232 to extend
lengthwise with sensor device 230.
[0056] FIG. 9 illustrates sensor device 230 of FIG. 7 in a
deflected position. The conductive elements 232 move relative to
one another when sensor device 230 deflects. For example, spacing
(labeled as H.sub.1) between conductive elements 232 in FIG. 8 is
relatively static from one end of the cross-section shown to the
other. But in FIG. 9, spacing between conductive elements 232 is
changed, and labeled as H.sub.2 and H.sub.3. Specifically, the
spacing between electrical elements 232 may be reduced, so that
H.sub.2 and H.sub.3 are both less than H.sub.1. Further, the
difference in spacing along sensor device 230 may no longer be
static, so that H.sub.2 is different than H.sub.3. The changes
between H.sub.2, H.sub.3 and H.sub.1, as well as between H.sub.2
and H.sub.3, may be used to measure a magnitude of the deflection.
As sensor device 230 is deflected, the spacing between conductive
elements 232 is altered, causing a fluctuation in the electrical
property. The fluctuation in the electrical property may be
detected and measured as an analog value that is subsequently
signaled to AD converter 134 (see FIG. 4).
[0057] In an embodiment, the electrical property that is fluctuated
and measured is a capacitance, existing between the conductive
elements 232 through electrical charge or current. Another
embodiment may use resistance or inductance between the conductive
elements 232, based on changes in charge as a result of positioning
of the electrical elements 232 before and after deflection.
[0058] C. Page Presentation
[0059] A page flicking mechanism such as shown with embodiments of
the invention enables a user to enter an input that reconfigures
the display 120 to present other pages of paginated content. The
other pages may be presented in various formats, preferably in
rapid succession, giving the user an impression that the pages are
being flicked. In an embodiment, the pages are presented on the
display for a duration corresponding to the user providing the
flicking input. In this way, the user can track the pages as they
are being presented in succession on the display. Further, the user
can select a page for viewing by stopping the flicking action.
[0060] FIGS. 10A-10C illustrate configurations for computing device
100, in which stored values of select pages are assigned to
discrete elements 322 of display 120 at times before, during and
after a page flick. For simplicity, the stored values for each
discrete element 322 are described and illustrated with reference
to bit values, although values for each discrete element may range
depending on the type of display. For example, color displays may
use color values using multiple bits.
[0061] The stored values that are to be assigned to each discrete
element of display 120 are part of a larger data collection
representing the paginated content. An example of a data collection
configured for paginated presentations is an electronic book. In an
embodiment, bit values of each page are stored in first memory 144
(FIG. 4) of computing device 100. Each bit value may be assigned to
appear on particular discrete elements 332 of display 120 when that
page is selected. Alternatively, values may be assigned to
different portions of the display 120 to enable the user to scroll
vertically or sideways and view portions of each page on the
display.
[0062] FIG. 10A-10C illustrates bit values from the data collection
at three durations: prior to receiving the page flick (t=0); during
the page flick (t=N); and after the page flick (t=F). The pages
assigned from each value are denoted by subscripts. The subscript 0
represents the current page. FIG. 10A shows that at t=0, processor
140 presents only the current page. The bit values from that page
appear on every discrete element 322.
[0063] Upon the page flick being entered by a user, FIG. 10B
illustrates the duration N, where pages are sequentially presented.
During the duration N, all or portions of display 120 presents
multiple pages in sequence, so as to be in flux. An embodiment
provides that the current page is presented on display 120
concurrently with another page that is continuously changed until
the page flick ends. The current page may be static and appear on
first display portion 310. A second display portion 315 may present
pages that are continuously changed. The bit values of the pages
that are continuously changed are denoted by the subscript J. The
pages denoted by J are part of a set presented on second display
portion 315 during the duration t=N. The page numbers in the set of
pages may range in either direction from the current page,
depending on a value of the page flick. The page numbers denoted by
J may also skip, or follow one another sequentially. For example,
for a large page flick value, the page numbers contained in the set
denoted by J may skip. In addition, the number of pages appearing
in the set denoted by J may depend on the value of the page flick.
For any duration, the page flicking value may be slow or fast. The
duration of N may include more pages in the set of J for larger
page flick values.
[0064] In an embodiment, second display portion 315 is positioned
on the most viewable length of display 120. That may correspond to
a centrally positioned strip having a width that is only a
proportion of the overall width of display 120. If display 120 is
bendable, second display portion 315 may correspond to a length of
display 120 appearing left of the display's center line. The left
side is most viewable if the user is bending a right end of display
120.
[0065] FIG. 10C illustrates display 120 at t=F, where discrete
elements 322 assert bit values from the final page selected by the
user as a result of the page flick. The final page is represented
by bit values with subscripts K. In the natural order of the data
collection (i.e. sequential page numbers of a book), K may precede
or be subsequent to the page represented by the subscripts 0 and J.
The page K may be selected as a result of the user viewing one of
the many pages presented during the interval N.
[0066] While embodiments described with FIGS. 9A-9C describe the
current page as being presented concurrently with other pages being
flicked, other embodiments may dedicate the entire area of display
120 for pages that are flicked. While this would require more
processing and memory resources, the visual effect may be easier to
view by the user.
[0067] Another embodiment may display only portions of each page
being flicked. For example, second display portion 315 may blank
every other row of discrete elements 322. The result would be that
the portion of display 120 used for displaying flicked pages is
blurred, while giving the user sufficient page presentation to
enable the user to be able to identify features of characteristics
of each page flicked. Blurring the flicked pages in this manner
preserves memory and processing resources of computing device
100.
[0068] Still further, the computing device 100 may be configured to
intelligently blur or omit data from the pages being flicked.
Substantially blank pages may be skipped during page flicks. Blank
lines or pages may be omitted.
[0069] D. Other Embodiments
[0070] While embodiments described herein for computing device 100
describe housing 210, it is possible for computing device 100 to
not have a housing that is separate from display 120. For example,
certain types of electronic paper in production may form the top
panel 212 of the housing 210 for computing device 100.
[0071] Under another embodiment, a page flicking mechanism may be
coupleable to a handheld computer to enable users to flick pages of
paginated content provided on the handheld computer. A page
flicking mechanism comprising sensor device 230 may be coupled to a
port of a handheld computer. Examples of handheld computers for use
with such an embodiment includes personal digital assistants
(PDAs), such as those manufactured by Palm Inc., or those operating
WINDOWS POCKET PC operating systems. The page flicking mechanism
may communicate with a processor of the handheld computer through a
serial port, wireless port (having infrared, BlueTooth or
radio-frequency characteristics), or other communication ports,
such as Universal Serial Busses (USB).
[0072] In the foregoing specification, the invention has been
described with reference to specific embodiments thereof. It will,
however, be evident that various modifications and changes may be
made thereto without departing from the broader spirit and scope of
the invention. The specification and drawings are, accordingly, to
be regarded in an illustrative rather than a restrictive sense.
