[00331 When the ele.ctronic device 300 is enabled for two-way communication within the wireless communication network 319 as depicted in FIG. 3, it can send and = receive signals from a mobile communication service. Examples of communication 5. systems enabled for two-way communication include, but are not limited to, the General .
Packet Radio Service (OPRS) network, the Universal Mobile Telecommunication Service (UMTS) network, the Enhanced Data for Global Evolution (EDGE) network, the Code Division. Multiple Access (CDMA) network, High-Speed Packet Access (HSPA) networks, Universal Mobile Telecommunication Service Time Division Duplexing (UMTS-TDD), Ultra Mobile Broadband (UMB) networks, Worldwide Interoperability for Microwave Access (WiMAX), and other networks that can be used for data and . ' voice, or just data or voice_ For the systems listed above, the electronic device 300 can require a unique identifier to enable the electronic device = 300 to (transmit and receive signals from the communication network 319. Other systems can .not require such identifying information. GPRS, U1VITS, and EDGE use a Subscriber Identity Module=' = (SIM) in order to allow communication with the communication network 319.
Likewise, most CDMA systems use a Removable Identity Module (RUIM) in order to communicate =
with the CDMA network. The- RUIM and SIM card can be used in multiple different " .
electronic devices 300. The electronic device 300 can be able to operate some features without a srmaumm card, but it will not be able to. cornm.unicate with the network 319.
= A SIM/RUIM interface 344 located within the electronic device 300 allows for removal or insertion of a SIM/RUIM card (not shown). The SIM/RUIM card features memory-- = - -= -=
and holds key configurations 351, and other infomiation 353 such as identification and subscriber related information. With a properly enabled electronic device 300, two-way = 25 communication between the electronic device 300 and communication network 319 is possible.

[00341 When equipped for twO-way communication, the handheld electronic device 300 also features a communication subsystem 311 as indicated in FIG. =
3. The communication subsystem 311 can modified so that it can support the operational needs .of the handheld device 300. As shown in FIG. 3, the subsystem 311 includes =
a transmitter 314 and receiver 312 including the associated antenna or antennae 316, 318 as described above, local oscillators (L0s) 313, and a processing module 320 which in the =
= presently. described exemplary embodiment is a digital signal processor (DSP) 320.
=
[0035] If the han.dheld electranic device 300 is enabled as described above, or the = 10 communication network 319 as shown in FIG. 3 dOes not require such enablement, the = two-way communication enabled handheld device 300 is able .to both transmit and receive information from the communication network 319.
The transfer of communication can be to and froni the handheld device 300. In order to communicate =
with the communication network 319, the handheld device 300 in the presently described exemplary embodiment is equipped with an integral or internal antenna 318 for transmitting signals to the communication network 319. Likewise the handheld electronic device 300 in the presently described exemplary embodiment can be equipped =
with another antenna 316 for receiving communication from the cornmunication network 319. These antennae 316, 318 in another exemplary embodiment can be combined into a single anteruia (not shown).

While some users will grasp the handheld device 300 in both hands when entering text as in FIG. 2A, it is also possible for users to cradle = the handheld device 300 in one hand in such a manner that inPut and control over the handheld device 300 can be effected using the thumb of the same hand in which the = handheld device 300 is held. However, it is appreciated that additional control can be effected by using both hands_ As a handheld device 300 that is easy to grasp and = 20 desirably pocketable, the size of the handheld device 300 must be kept com,mensurately - small. Of the device's dimensions, limiting its width is important for the=
purpose of = = assuring cradleability in a user's hand. . . . . . .
[0041] However, some users can find it difficult to operate because of the reduced size. The dual-hinged intercormector 80 gives an increase in 'surface area and a protruding surface to grasp as well. The extended nature of the dual-hinged .
interconnector 80 allows the clam-shell style handheld electronic device 300 to be held = between the fingers of both hands. Thus, the interconnector can act as a handle of sorts.

[0042] = Additionally, the small size of the handheld device 300 can be a drawback in that there is limited exterior surface area for the inclusion of user input and device output features. This is especially true for the "prime real estate" on the face of the keyboard: housing .640 of the handheld device 300 in the open configuration 601_ Furthermore, as shown in the embodiment of FIG. 2A, the display screen 322 is located above a keyboard 650 :that is utilized for data entry into the handheld device 300 by the user, and above a navigation tool 327 which is located on the interior surface of the dual-hinged interconnector. If the screen 322 is provided below the keyboard 650, a =problem =
occurs in that viewing the screen 322 is inhibited when the useris inputting data using the keyboard 650. Therefore, in the embodiment shown in FIG. 2B, the display screen 322= is above the navigation row 70 and keyboard 650, thereby Solving the problem by assuring that the hands and fingers do riot block the view of the screen 322 during data .entry periods. This property is enhanced by the fact that the angle between the interior surface of the keyboard housing .640 and the interconnector 80, and the angle between the = interconnector 80 and the display face 320 can each. take separate values, and thus more positional options exist for the user.

Because they are connected via hinges, the angle Ai between the display housing 95 and the keyboard = housing 90, the angle A2 between the back of the interconneotor 81 and the display = housing, and the angle A3 between the= interconnector 80 and the keyboard housing 90 are =

[0040] One of the important aspects of the handheld electrdnic device 300 to which this disclosure is directed is its size. While some users will grasp the handheld device 300 in both hands when entering text as in FIG. 2A, it is also possible for users to cradle = the handheld device 300 in one hand in such a manner that inPut and control over the handheld device 300 can be effected using the thumb of the same hand in which the = handheld device 300 is held. However, it is appreciated that additional control can be effected by using both hands_ As a handheld device 300 that is easy to grasp and = 20 desirably pocketable, the size of the handheld device 300 must be kept com,mensurately - small. Of the device's dimensions, limiting its width is important for the=
purpose of = = assuring cradleability in a user's hand. . . . . . .
[0041] However, some users can find it difficult to operate because of the reduced size. The dual-hinged intercormector 80 gives an increase in 'surface area and a protruding surface to grasp as well. The extended nature of the dual-hinged .
interconnector 80 allows the clam-shell style handheld electronic device 300 to be held = between the fingers of both hands. Thus, the interconnector can act as a handle of sorts.
-1137875v1 =
= 14 Moreover, this configuration enhances stability and hence makes thumb attivation of the keys on keyboard housing 640. =
[0042] = Additionally, the small size of the handheld device 300 can be a drawback in that there is limited exterior surface area for the inclusion of user input and device output features. This is especially true for the "prime real estate" on the face of the keyboard: housing .640 of the handheld device 300 in the open configuration 601_ Furthermore, as shown in the embodiment of FIG. 2A, the display screen 322 is located above a keyboard 650 :that is utilized for data entry into the handheld device 300 by the user, and above a navigation tool 327 which is located on the interior surface of the dual-hinged interconnector. If the screen 322 is provided below the keyboard 650, a =problem =
occurs in that viewing the screen 322 is inhibited when the useris inputting data using the keyboard 650. Therefore, in the embodiment shown in FIG. 2B, the display screen 322= is above the navigation row 70 and keyboard 650, thereby Solving the problem by assuring that the hands and fingers do riot block the view of the screen 322 during data .entry periods. This property is enhanced by the fact that the angle between the interior surface of the keyboard housing .640 and the interconnector 80, and the angle between the = interconnector 80 and the display face 320 can each. take separate values, and thus more positional options exist for the user.
= =
[0043) Another positional option for the user is to set the device down 300 temporarily, as in FIG. 2B (and also FIG. 15). = If the user places the device on. a fiat - = =
surface a user Can derive a benefit from being able to view the display screen 322 without having to lift the device 300 by hand. As can be seen from FIG_ 2B, the dual-hinged interconnector 80 can act as a stand which props up the display housing 95.
Because they are connected via hinges, the angle Ai between the display housing 95 and the keyboard = housing 90, the angle A2 between the back of the interconneotor 81 and the display = housing, and the angle A3 between the= interconnector 80 and the keyboard housing 90 are =
1157675v1 =
all adjusvable. This adjustability, coupled With the stand action of the interconnector, 80 Means that a user will be able to adjust the display screen 322 for maintenance of visual contact while the device 300 is in a resting orientation 303.
=
5 [0044] PIG. 8 shows the front of an embodiment of the clam-shell style handheld electronic device 300 in a closed configuration. In a closed configuration 600 a display screen 322 and a keyboard 650 can be wholly or partially covered.. The device 300 can be equipped With an external mirror (not shown), a camera, 851, a flash 852 for use in conjunction therewith as well as a light emitting diode 853. Those skilled in the art will 10 appreciate that these items could have different positions and still come within 'this disclosure. In the embodiment shown FIG. 8 the dual-hinged interconnector 80 has a length L3 which is greater than at least twenty percent of the length of the display housing LI. This allows for the interconnector 80 to act as both a stand and a handle as set forth = previously. =
= [0045] FIG. 9 shows the sear or back of an embodiment of the device 300 in a *closed configuration 600. A fast side 81 of the dual-hinged interconnector 80 is shown in a mutually accommodating relationship with the keyboard housing 90. Two charge = contacts 807 are shown towards the lower portion of keyboard housing 90.
The keyboard = 20 housing 90 can be seen to have a substantially .square profile 800. .A5 will...be appreciated= .

electronic device 300, others are possible while still falling.within-the present disclosure. = = -= In the embodiment shown, the dual-hinged interconnector 80 has a length L3 greater than at least twenty percent of a length Ll of the longer of the . display housing 95 and the keyboard housings 90, and the lengthwise= longitudinal axes of each of the display housing 95 and the keyboard housings 90 and dual-hinged interconnector 80 are shown oriented substantially parallel, one to the others. However, those skilled in the art will =
1137675v1 =
=
. appreciate that the dual-hinged interconnector 80 or the display housing 95 or keyboard housing 90 could be constructed in various proportions within this disclosure.
=[0046] A closed configuration 600 from the right side is also shown FIG.
10.
Although it is compact, the device 300 has multiple input and output faculties, even *hen inthe closed configuration 609. For example, a programmable key 120, a universal serial bus port 874 and a. headset jack 875 are shown op the exterior of the device 300 on the " display housing. Those skilled in the art will appreciate that the programmable keys of the device 105, 120 can be programmed to have multiple functions, allowing the keys to activate a camera, act as an alternate mute button, a function cancel button, among other = things. In =at least one example as illustrated in FIG. 10, some portion of the keyboard 650 can be igen between the keyboard housing 90 and display housing 95. In another .
.possible embodiment the device 300 could be so configured so as to completely conceal the keyboard 650 when viewed from the same side as in FIG_ 10 while still coming 15. within this disclosure. Also, the dual-hinged interconnector 80 can be seen between and = above the hinge-end covers 900 in the illustrated.example. In the embodiment pictured in = FIG. 10, the thickness of the interconnectcir TT is equal to the combined thickness of the display housing 95 and the keyboard housing 90. The connectors could be located on the =
sides of the interconnector 80 closest to the housings 95, 90 and parallel to the lengthwise axis, or on the sides which are closest to the housings 95, 90 but perpendicular to said = axis. .
(0047] The other side view of the device 300 in a closed configuration 600 is shown in FIG. 11. Even though the embodiment- is streamlined and compact, multiple input and output options exist. For example, in the embodiment of FIG..11, the volume =
buttons or keys 100 in the keyboard housing 90 are situated next to a user-progtammable key 105. The volume buttons or keys can be configured so as to adjust the speaker (not shown) volume when -the device 300 is used a telephone or to adjust the volume of the =
audio output associated with other finictionalities.
FIG: 11 shows the dual-hinged = = interconnector 80 between and above two hinge-end covers 900. As will be described further herein, still other input and output options can be provided on the exterior of the device 300. Again, as will be appreciated by those in the art; while a particular shape is shown, others are possible while still falling within the present disclosure, for example handheld electronic device 300 might be more or less oblong when closed 600, the sides = could be fashioned to be soMewhat arcuate, thus giving the device a near oval shape.
[0041 The top of an embodiment of the device 300 _in a closed configuration 600 = 10 = is depicted in. FIG. 12.. A mute/suspend key 880 is shown on the left side of the exterior = of the .dual-hinged intercormector 80 and a speaker phone button 890 is on the right.
Such locations are examples only, and other possibilities exist within the.
present disclosure. Also, other keys or buttons can be located on the dual-hinged interconnector 80 which can take various shapes. Within the dual,hinged interconnector resides a spring 15* assembly (not shown) which runs through interconnector 80 to the hinge-end covers 900.
[00491.
Both FIGS. 12 and 13= show an embodiment wherein the dual-hinged = interconnector 80 is of a width Wy which is substantially equal to the width of the display housing Wxi and the width of the keyboard housing W. Other embodiments having = 20 different widths are possible within this disclosure. For example, the widths mentioned could range between six and nine centimeters. = Making the handheld electronic device 300 wider than nine inches would probably be undesirable due to a loss in convenience of storage--it would not fit in the average pocket or hand.
25 [0050] The compact nature of the device 300, which is at least in part made =
possible by the dual-hinged intercoruiector 80, is shown in FIG. 13. The thinness of the = device 300 can be seen in FIG. 13 insofar as the thickness of the dual-hinged = interconnector TT in FIG. 12= is the same as the sum of the thickness of the keyboard = 11376i5v1 18 =

Additionally, indicia for the key can be temporarily shown nearby the key on =the display screen 322. As will be = appreciated by those in the art,, physical. and virtual keys can be .combined in many different ways. In one embodiment, physical and virtual keys could be cOmbined such that the plurality of enabled keys for a particular application or feature of the handheld = 15 electronic device 300 is shown on the display screen 322 in the same configuration as the ' physical keys. Using this configuration, the user can 'select the appropriate physical key corresponding to what is shown on the display screen 322. Thus, the desired character, command or function is obtained by depressing the physical key corresponding to the character, command or function displayed at a corresponding position on the display screen 322, rather thanlouching the display screen 322.
- [0053] As made clear previously, the clam-shell style handheld electronic device = == = --309 is configured to send and receive voice communications such as mobile telephone call and the fimctionality of the device can be afforded to the operator through designated keys_ .For example, two call keys 660, 670 can be provided below the navigation row 70 (so-called because it includes the -navigation tool 327) as shown in FIG_ 14 which can facilitate telephone usage. One of the two call keys is a call initiation key 660, and the other is a call termination key 670. The navigation row 70 also includes another pair of 1137675v1 =
