Full Text [0001] A COMMUNICATION DEVICE HAVING MULTIPLE KEYPADS
[0002] BACKGROUND OF THE INVENTION
[0003] The present invention relates generally to a communication device and
particularly to acommunication device having multiple keypads, such as a wireless
telephone, having a plurality of independent, differently-configured keypads functionally
connected to a single display panel. As used herein, the term "functionally connected"
means that input from one of the elements in question affects the other element. In the
context of a keypad and display panel, input from the keypad (e.g., pressing a key or
rocking a joy button) affects what is displayed on the display panel (e.g., displaying a
letter or number, navigating a menu, or selecting a function). Of course, the
"connection" between such elements can be somewhat indirect. In the case of a keypad
and display panel, a display output circuit may change what appears on the display
panel in response to input from the keypad, for example.
[0004] Over the past decade, the number of wireless telephone users has grown
exponentially. As the number of users has grown, the demand for increased cell phone
functionality has also grown. For example, wireless telephones can now be used to
send and receive text messages and e-mail messages. Further, many wireless
telephones have video games, calculators and other electronic programs incorporated
therein.
[0005]- On prior art wireless telephones, each of the programs and functions is
controlled using a single standard alpha-numeric telephone keypad, or a single alpha-
numeric telephone keypad that has reconfigurable keys. However, because of the
aforementioned variety of programs and functions, a single standard keypad or a
reconfigurable alpha-numeric keypad is not user friendly and limits functionality.

[0012] DETAILED DESCRIPTION
[0013] The ensuing detailed description provides exemplary embodiments only, and
is not intended to limit the scope, applicability, or configuration of the invention. Rather,
the ensuing detailed description of the exemplary embodiments will provide those
skilled in the art with an enabling description for implementing the exemplary
embodiments of the invention. It being understood that various changes may be made
in the function and arrangement of elements without departing from the spirit and scope
of the invention, as set forth in the appended claims. In addition, reference numerals
that are introduced in the specification in association with a particular drawing figure
may be repeated in other figures without additional description in the specification in
order to provide context for other features.
[0014] A wireless communication device is shown in FIGS. 1-3 and is designated
generally by reference numeral 10. The wireless communication device 10 generally
comprises a front housing 12, a first keypad housing 14 and second keypad housing 16.
Each of the keypad housings 14, 16 houses a respective keypad 15, 17. Although the
wireless communication device is illustrated and described herein as having only two
independent keypad housings, it will be appreciated by one of ordinary skill in the art
that the device 10 could be provided with more than two independent keypad housings
without departing from the scope of the present invention.
[0015] The front housing 12 and keypad housings 14,16 can be arranged in various
configurations by sliding the front housing 12 and keypad housings 14, 16 transversely
in parallel planes relative to one another. In the "nested configuration" illustrated in FIG.
1, the front housing 12, first keypad housing 14 and second keypad housing 16 are
arranged in a stacked, overlapping configuration with the front housing 12 on top, the
first keypad housing 14 on the bottom, and the second keypad housing 16 in the middle.
In the configurations illustrated in FIGS. 2 and 3, the front housing 12 has been moved
to an "extended position" relative to the keypad housings 14, 16 so that one of the
keypads 15, 17 is exposed for functional operation by a user.
[0016] In the extended positions shown in FIGS. 2-3, the front housing 12 is
arranged in a parallel plane that is substantially non-overlapping with at least one
keypad (15 or 17) so that the keys of the keypad (15 or 17) are exposed and physically
accessible by a user. It should be noted that the term "keys", as used in the
specification and claims may include keys, buttons, and the like. In the extended
positions shown in FIGS. 2-3, the front housing 12 overlaps the exposed keypad along
a short length that connects the front housing 12 to the keypad housing (14 or 16).
[0017] Referring to FIG. 1, the communication device 10 has a width (W) and a
length (L) that is greater than the width. Each of the keypad housings 14, 16 and the
front housing 12 is generally-planar and rectangular. Each also has approximately the
same length and width, but different thicknesses. The communication device 10 may
be cellular telephone, a cordless telephone, a personal digital assistant, a wireless text
device, or the like.
[0018] The front housing 12 includes a faceplate 19, an earpiece loudspeaker 18, a
microphone 20, display panel 22, and a plurality of softkeys 24 arranged in the
configuration shown in FIG. 1. The loudspeaker 18, microphone 20, and softkeys 24
comprise components that are well known to one of ordinary skill in the art of wireless
telephones. The front housing 12 houses transceiver circuitry that provides a wireless
communication link with a base station, wireless local area network, a cellular system,
and/or a cordless telephone.
[0019] The illustrated display panel 22 has a generally rectangular shape and has
the same orientation as the front housing 12. In other words, the length (LD) and width
(WD) extend parallel to the length (L) and width (W), respectively, of the communication
device 10. Unlike typical wireless communication devices, the front housing 12 does not
include a standard telephone keypad. Therefore, the display panel 22 can be made
larger, compared to conventional wireless communication devices, without increasing
footprint of the front housing 12. Referring to FIG. 1, the display panel 22 extends along
at least 50% of the length of the front housing 12 so that extended alpha-numeric
messages can be displayed on the display panel 22 in both landscape and portrait
orientations.
[0020] The display panel 22 may comprise a conventional display, such as a liquid
crystal display (LCD). The front housing, or one of the keypad housings, houses
circuitry for receiving, processing and generating control signals for the display panel 22
such that text messages are automatically displayed. These messages, such as alpha-
numeric characters 34, are displayed on the display panel 22 in the same orientation,
either landscape or portrait, and in the same direction, as the graphic representations
on the keys of the exposed keypad. For example, referring to FIG. 2, the characters 34
are displayed in a landscape orientation and in the same orientation as the keys on the
keypad 17 exposed in this figure, whereas the characters are shown displayed in a
portrait orientation and in the same orientation as the keypad 15 exposed in FIG. 3.
[0021] Each of the keypads 15, 17 is functionally connected to the display panel 22
on the front housing 12 and has a key configuration that is different than the other. The
first, or telephone, keypad 15 has a standard telephone keypad configuration as seen in
FIG. 3, and the second keypad 17 has a text entry keypad, illustrated as a Roman
alphabet typewriter or computer keyboard (commonly referred to as "QWERTY")
configuration as seen in FIG. 2. However, the first, but preferably the second, keypad
15, 17 may comprise any other known keypad configuration such as the game keypad
configuration 115 provided in the alternative embodiment illustrated in FIG. 4. The
second, or text keypad 17, can be any suitable text entry device optimized for entry of
text in a desired language, such as Chinese, Japanese or Korean. By providing a single
common display panel 22 functionally connected to each of the keypads 15, 17, the cost
of the communication device 10 is reduced compared to a providing a respective
display panel for each keypad 15,17.
[0022] The front housing 12 and keypad housings 14, 16 telescopically slide
transversely relative to one another in overlapping, parallel planes. In the nested
configuration, each of the keypads 15, 17 is concealed underneath the front housing 12.
Each of the keypads 15, 17 can be selectively exposed by sliding the front housing 12 in
the lengthwise or widthwise direction to an extended position. Referring to FIG. 2, the
second or middle keypad 17 is exposed by sliding the front housing 12 in the widthwise
direction.
[0023] Referring to FIG. 3, the first or bottom keypad 15 is exposed by sliding the
front housing 12 in the lengthwise direction. Because of the manner in which the front
housing 12 and keypad housings 14, 16 are connected, lengthwise movement of the
front housing 12 simultaneously drags or slides the second keypad housing 16
lengthwise to expose the first keypad 15. As described above, the display panel 22
automatically displays the characters on the display panel 22 in the same orientation
and direction as the keys on the exposed keypad (15 or 17).
[0024] The first keypad 15 is exposed only when the front housing 12 moves from
the nested configuration along a first path of travel, and the second keypad 17 is
exposed only when the front housing 12 moves from the nested configuration along a
second path of travel different than the first path of travel. The paths of travel are linear
and transverse to one another. For example, only the middle, landscape-oriented
keypad 17 is exposed when the front housing 12 slides from the nested configuration in
the widthwise direction, while only the bottom, portrait-oriented keypad 15 is exposed
when the front housing 12 slides from the nested configuration in the lengthwise
direction. However, it should be appreciated by those skilled in the art that this
configuration can be reversed without departing from the scope of the invention. In
other words, the front housing 12 and keypad housings 14, 16 could be arranged so
that the landscape-oriented keypad 17 is exposed when the front housing 12 slides in
the lengthwise direction and the portrait-oriented keypad 15 is exposed when the front
housing 12 slides in the widthwise direction.
[0025] In the embodiment illustrated in FIGS. 1-3, the softkeys 24 are functional
when either keypad 15, 17 is exposed. Further, the softkeys 24 could be functionally
connected to the display panel 22 to control different functions depending on whether
the first 15 or second 17 keypad is exposed.
[0026] Referring to FIGS. 2-3, the front housing 12 and second keypad 17 are
connected by opposed pairs of cooperating slides arranged on the widthwise-extending
edges of the front housing 12 and second keypad housing 16. The slides limit
movement of the front housing so that only one keypad can be exposed at a time. The
widthwise edges of the front housing 12 and second keypad housing 16 have
cooperating C-shaped guides 26, 28. In a similar manner, the first keypad housing 14
and second keypad housing 16 are connected by opposed pairs of cooperating slides
arranged on the lengthwise-extending edges of the first 14 and second 16 keypad
housings. The lengthwise edges of the first keypad housing 14 and second keypad
housing 16 have cooperating C-shaped guides 30, 32. Other types of guide
arrangements, such as tongue and groove arrangements, can be used.
[0027] The communication device 10 is portable, and such devices typically employ
a battery (not shown). It is envisioned the battery will be advantageously located within
the housing 14 of the lowest keypad 15, to facilitate access for changing the battery.
Alternatively, the battery may be housed within the front housing 12 or the intermediate
keypad housing 16.
[0028] A wireless communication device 110 in accordance with another
embodiment of the invention is shown in FIG. 4. Similar to the previous embodiment,
the wireless communication device generally comprises a front housing 112, first
keypad housing 114 and second keypad housing 116. The front housing 112 includes a
faceplate 119, an earpiece loudspeaker 118, a microphone 120, display panel 122, and
a plurality of softkeys 124 arranged in the configuration shown in FIG. 4. The front
housing 112 and keypad housings 114, 116 are similar in construction to the wireless
communication device 10 described above except that the second keypad 117 has a
game pad configuration instead of a QWERTY keypad. The game pad configuration is
designed to be used to play games and includes a 4-way toggle switch or joystick.
[0029] While the principles of the invention have been described above in connection
with illustrated embodiments, it is to be clearly understood that this description is made
only by way of example and not as a limitation of the scope of the invention.
