A, unique fea$ure of the radiotelephone 10 is readily 5 apparent from viewing both FIGs. 1 and 2. The first housing portion 12 has an end portion 22. The second housing portion 14 has an end portion 24 extending beyond the end portion 22 of the first housing portion 12 when the first 12 and the second 14 housing port,ions are moved to their first respective housing 1 0 position 18 at least partially covering the side 32 of the third housing portion 16. Preferably, the length of the first 12 housin~ portion and the length of the second 14 housing ~:
portion are each greater than one-half the len~h of the third ' housing portion 16.
:
A conventiona1 earpiece transducer 26 is coupled to the first housing portion 12 and a conventional microphone '~
:: transducer 28 is coupled to the second housi~gportion 14~ The earpiece 26 and microphone 28 transducer~ are substantially ~ ~-allgned with a center axis 30 of the third housing po~ion 16.
Conventional transceiving means (see FIG. 7), eoupled to the eàrpiece 26 and microphone 28 transducers, is preferably disposed in the third housing po~ion l6.
In tne closed~housing position 18, thè first 12 2nd second 14 housing portions are substantially disposed in the same plane and pref~ably adjacent to ~e side~ 32 of the third -~
housmg portion 16. Preferably, a side 34 of the first housin~
portion 12 is shaped to matively engage with a ~id2 36 of the ~ -second housingportion 14. Such engagement permits the positioning ofthe first 12 and second 14 housingportionsin the same plane adjacent to the side 32 of the third housing :
portion lff while permit ngthe earpiece 26 andmicrophone 28 transdusers to align with the center axis 30.

.: -Note that in the closed position 18, the holes in the earpiece 26 and microphone 28 transducers are facing towards the side 32 of the third housing portion 16. This ;
produces a very clean appearance on the outside of the radiotelephone 10 wheninits closed position 18. ~ ;
In the open housing position 20, the first housing portion 12 is disposed at an obtuse angle relative to the third housing portion 16, preferably 180~, permitting aligNnent of the earpiece transducer 26 with a human ear. ~Cinnil~rly, the second housing portion 14 is also disposed at ~n obt~lse angle relativ~ to the third housing portion 16, although preferably :-135~, permitti~g ~ nment of the microphone transducer 28 ;
with a human mouth. Both the earpiece 26 and microphone 28 transducers remain aIigned with the center axis 30 when the first 12 and second: 14 housing portions are in the open housing posihon 20.

WO 94113088 '~ PC'rlU~93/11291 The mo~rement of the first housing portiorl 12 between the closed 18 and open 20 housin~ positions can be coupled to the mo~rement of the second housing portion 14 between the closed 18 and open 20 housing positions. Due to the sculptured shape of the first 12 and second 14 housing portions, one of the -~
housing portions must rotate a predetermined number of degrees relative to tbe third housing portion 16 before the other housing portion can rotate so that the first and second housing portions do not interfere with each other. The first hol~sing portion 12 is retained in the closed position 18 using the hinge mechPnism 38. The second housing portion 14 :
includes a conventional spring member as shown in U.S. ~;
Patent No. 4,471,493 coupled ~ the hinge me~h~ni~m 40. The spring member generates a biasing force to urge the second :
h~usLng portion 14 to its open position 20. A tab 42 coupled to the end portion 24 of the second housing portion 14 is adapted ~:
to fit within a recess~ 44 in the area of the hinged me~h~nism 38 of the first housing portion 12 to maintain the second ~: ~20 ~ housing portion 14 in its closed position 18 when the first ~-housing portio~ l2 is in its closed position 18. When the first :
housing portion 12 is~ manually moved to the open position 20, the tab 42 clears the recess 44 permitting the biasing force e~Eerted by the spnng member to urge the second housing ~portion 14 to its ~pen position 20. The radiotelephvne 10 may ~ :~
be~ thereafter closed by closing the first housing portion 12 af~er the secor~d housing por~ion 14. Of course, more elaborate coupling meçh~ni~ms may be employed to auto~ cally open each of the first 12 and the second 14 housing portions.
The radiotelephone 10 is advantageous in that is ~ ~
contracted to a~ o~ ately one third of its useable length - ~:
when in its closed position 18 while providing only one '~
: ~ additional layer of housing material. This resu~ts in a reduction in thickness of the device and a weight reduction :~
.
, , WO 94/13088 PCT/US93/11291 . -- , . 6 approximately equal to that of one moveable housing portion.
Furthermore, when the radiotelephone 10 is expanded ~o its open position 20, the earpiece 26 and microphone 28 transducers remain on the center axis 30 of the third housing ;:
portion 10 perrnitting convenient and comfortable ~li~ment ~:
with a human ear and mouth.
The radiotelephone 10 further includes a display 46 and ~ ' a data input device, such as a keypad 48, preferably coupled to the side 32 of the third housing portion 16. As the ~-radiotelephone 10 becomes s~aller, less space is available for - :~
the display 46 ~d keypad 48. However, radiotelephones are being designed with more capability to provide a greater range of services and thus need additional display 46 and keypad 48 resources to support the expanded capability. One such example of added capability is the addition of a selective call receiver fimctions, such as a conYentional pager, to the ~-~nctionality o~ the radiotelephone 10. A conventional pa~er ~ --may be of the type model number A04JRC5661A, ~ ~
manu~actured and available from Motoro~a lnc. 1500 N.W. : ;~~
2ndAvenue,Bo~TntonBeach~ ~] 33426-8292~ Thecombination ~ ' of a pager and a radiotelephone is already well known in the .
~: art.
Such expanded capability problems are overcome by --~
: relating paging ~nd radiotelephone modes associated with :~.
the wireless communication device lQ to at least one of the first 12 and seconrl 14 housing portions being moved ~etween : the closed l8 anrl :opén 20 positions. The movement of one housing portion actuates a ~witch (see FIG. 7) to prompt the dévice to change a portion of the communication device ~: : bet~;veen paging and radiotelephone fi~nctions. A switch ~: actuated responsive to the mo~ement of a housing portior~ is ~ ~
well known as:taught, by example, in U.S. Patent No. Q'.' :~5 ~,117,~73. ;-, ' . ~
WO ~4113088 2 i 2 ~ P~TIUS93/11291 For example, display functionality is expanded by displaying paging information when the first housing portion 12 is mo~red to the closed position 18 and radiotelephone information when the first housing portion 12 is moved to the open housing position 20. :
:For example, keypad filnctionality is expanded by -' ha~ g paging functions associated there~nth when the first :~
housing porti~n 12 is in the closed position 18 and : :~
radiotelephone functions associated therewith when thP first housing portion 12 is moved to the open housing position 20.
The dual modes of the device sre not limited to only radiotelephone and paging functions. This feature of the present invention is intçnrled to include any two modes of the :: wireless communication device. For example, the dual modes :-:
alternatiYely inc1ude: radiotelephone vs. notebook func~ions, pIivate vs. hands-~ree conversation and cellular vs. cordless ~;
funct1ors.
;~ : The display 46 and keypad 48 are preferably coYered by ~
the moveable housing portions as shown in FIGs. 1 and 2, but ~ ::
do not necessa2 ily need to be coYered to gain the expanded fi~ctionality pr~ided by the moveable housing porti~n. An : example of a radiotelephone that has~a moveable housing ' ~
portion and does not fully co~rer the keypad is cordless ' ~:
: ra~iotelephone m~del number 34986, manufactured and available ~om Motorola Inc., 600 North U.S. Highway 45, Libertyville, n 60048. :
: ! , : . .
Another unique feature of the wire1ess somIIlunication de~rice 10 as shown in FIGs. 1 and 2 is a substD~nti y . .' transparent portion 50, hereinafter called a lens, coup~ed to ~ ' -35 the first 12 and ~second 14 housing portions. Since the display . ,.
. ~'"'' '~',,'' WO 9d,/130S8 ~ ~ ~, 7 r~ 6 S PCT/US93111291 4~ is at least partia1~y covered by the first housing portion 12 when the first housing portion 12 is moved to the closed housing position 18~ the display traditionally becomes of little use. Howe~er, the lens 50 is coupled to the first 12 and second 14 housing portions such that the lens is disposed essentially opposite at least a portion of the display 46 when the first 12 and second 14 housing portions are moved to the slosed housing position 18. Thus, the display capability is expanded ~;
since it can now be used when the housing portions are in their closed position 18. Of course, the lens may optionally be coupled to only one of the moveable housing portions if so desired. In accordance with the previously taught expanded ~-~
keypad feature, the covered display 46 provides paging information when the housing portions are moved to their ~;
respective closed housing position 18 and radiotelephone information when the housing portions are rnvved to their respective open 20 hou~ingposition.
-~; .
Still another unique feature of thP wireless ~:
:; 20 communication device 10 as shown in FIGs. 1 and 2 is keycap : '~
means 52 coupled to the second housing portion 14. Since the :: keypad 48 is at least part~ally covered by the second housing portion 14 wh the second housing portion 14 is moved to the closed housing position 18, the keypad 48 traditionally becomes of llttle use. However, th~ keycaps 52 are coupled to the second housirlg portion l4 such that the keycaps S2 are disposed esser t,i~11y opposite at least a portion of the keypad 54 when the second housing portion 14 is moved to the closed housing position 18. The: keycaps 52 are comprised of convenhonal elastomeric material and protrude through the thickness of thei second housing portion 14. The keycaps 52 are coupled to the second houslng portion 14 by sandwiching webbing interconnesting indi~idual keycaps between layers of ~he - second housing portion 14. Thus, the keypacl cap~bility is 35 expanded since it can now be used when the second housing ... ':
....
~ "
portion 14 is in its closed position 18. Of course, additional keycaps may alsn be coupled to the first housing portion 12 if - ~---so desired. In accordance with the prenously taught expanded keypad feature, the covered portion of the keypad 54 pro~rides paging functions when the second housing portion 14 is moved to its closed housing position 18 and radiotelephone functions when the second housing portion 14 is moved to its open housing position 20. :
Yet, still another ~nique feature of the ~reless ~;
communication device 10 as shown in FIGs. 1 and 2 is an antenna 56 coupled to the first housing portion 12. A
tran~ceiver (FIG. 7) is su~stantial~y disposed in the third housing portion 16. The antenna 56 is coupled ~ the transceiver and the first housing portion 12. The antem~a ~6 is -: .
moveable between a first, closed, antenna position desi~nP~ted ~: ~ by re~erence numeral 60 at pocket 58 and a second, open, ~ -antenna po~sition design~ted by reference numeral 62 extended beyond the first housing portion 12. The antenna ~6 is shown to be rotatably coupled to the first housing portion 1~ between anterma positions 60 and 62. The antenna preferably extends beyond the housing portion having the earpiece trarlsducer 26 ~.
such that the antenna extends above a human head.

A, unique fea$ure of the radiotelephone 10 is readily 5 apparent from viewing both FIGs. 1 and 2. The first housing portion 12 has an end portion 22. The second housing portion 14 has an end portion 24 extending beyond the end portion 22 of the first housing portion 12 when the first 12 and the second 14 housing port,ions are moved to their first respective housing 1 0 position 18 at least partially covering the side 32 of the third housing portion 16. Preferably, the length of the first 12 housin~ portion and the length of the second 14 housing ~:
portion are each greater than one-half the len~h of the third ' housing portion 16.

WO 94113088 '~ PC'rlU~93/11291 The mo~rement of the first housing portiorl 12 between the closed 18 and open 20 housin~ positions can be coupled to the mo~rement of the second housing portion 14 between the closed 18 and open 20 housing positions. Due to the sculptured shape of the first 12 and second 14 housing portions, one of the -~
housing portions must rotate a predetermined number of degrees relative to tbe third housing portion 16 before the other housing portion can rotate so that the first and second housing portions do not interfere with each other. The first hol~sing portion 12 is retained in the closed position 18 using the hinge mechPnism 38. The second housing portion 14 :
includes a conventional spring member as shown in U.S. ~;
Patent No. 4,471,493 coupled ~ the hinge me~h~ni~m 40. The spring member generates a biasing force to urge the second :
h~usLng portion 14 to its open position 20. A tab 42 coupled to the end portion 24 of the second housing portion 14 is adapted ~:
to fit within a recess~ 44 in the area of the hinged me~h~nism 38 of the first housing portion 12 to maintain the second ~: ~20 ~ housing portion 14 in its closed position 18 when the first ~-housing portio~ l2 is in its closed position 18. When the first :
housing portion 12 is~ manually moved to the open position 20, the tab 42 clears the recess 44 permitting the biasing force e~Eerted by the spnng member to urge the second housing ~portion 14 to its ~pen position 20. The radiotelephvne 10 may ~ :~
be~ thereafter closed by closing the first housing portion 12 af~er the secor~d housing por~ion 14. Of course, more elaborate coupling meçh~ni~ms may be employed to auto~ cally open each of the first 12 and the second 14 housing portions.
The radiotelephone 10 is advantageous in that is ~ ~
contracted to a~ o~ ately one third of its useable length - ~:
when in its closed position 18 while providing only one '~
: ~ additional layer of housing material. This resu~ts in a reduction in thickness of the device and a weight reduction :~
.
, , WO 94/13088 PCT/US93/11291 . -- , . 6 approximately equal to that of one moveable housing portion.
Furthermore, when the radiotelephone 10 is expanded ~o its open position 20, the earpiece 26 and microphone 28 transducers remain on the center axis 30 of the third housing ;:
portion 10 perrnitting convenient and comfortable ~li~ment ~:
with a human ear and mouth.
The radiotelephone 10 further includes a display 46 and ~ ' a data input device, such as a keypad 48, preferably coupled to the side 32 of the third housing portion 16. As the ~-radiotelephone 10 becomes s~aller, less space is available for - :~
the display 46 ~d keypad 48. However, radiotelephones are being designed with more capability to provide a greater range of services and thus need additional display 46 and keypad 48 resources to support the expanded capability. One such example of added capability is the addition of a selective call receiver fimctions, such as a conYentional pager, to the ~-~nctionality o~ the radiotelephone 10. A conventional pa~er ~ --may be of the type model number A04JRC5661A, ~ ~
manu~actured and available from Motoro~a lnc. 1500 N.W. : ;~~
2ndAvenue,Bo~TntonBeach~ ~] 33426-8292~ Thecombination ~ ' of a pager and a radiotelephone is already well known in the .
~: art.
Such expanded capability problems are overcome by --~
: relating paging ~nd radiotelephone modes associated with :~.
the wireless communication device lQ to at least one of the first 12 and seconrl 14 housing portions being moved ~etween : the closed l8 anrl :opén 20 positions. The movement of one housing portion actuates a ~witch (see FIG. 7) to prompt the dévice to change a portion of the communication device ~: : bet~;veen paging and radiotelephone fi~nctions. A switch ~: actuated responsive to the mo~ement of a housing portior~ is ~ ~
well known as:taught, by example, in U.S. Patent No. Q'.' :~5 ~,117,~73. ;-, ' . ~
WO ~4113088 2 i 2 ~ P~TIUS93/11291 For example, display functionality is expanded by displaying paging information when the first housing portion 12 is mo~red to the closed position 18 and radiotelephone information when the first housing portion 12 is moved to the open housing position 20. :
:For example, keypad filnctionality is expanded by -' ha~ g paging functions associated there~nth when the first :~
housing porti~n 12 is in the closed position 18 and : :~
radiotelephone functions associated therewith when thP first housing portion 12 is moved to the open housing position 20.
The dual modes of the device sre not limited to only radiotelephone and paging functions. This feature of the present invention is intçnrled to include any two modes of the :: wireless communication device. For example, the dual modes :-:
alternatiYely inc1ude: radiotelephone vs. notebook func~ions, pIivate vs. hands-~ree conversation and cellular vs. cordless ~;
funct1ors.
;~ : The display 46 and keypad 48 are preferably coYered by ~
the moveable housing portions as shown in FIGs. 1 and 2, but ~ ::
do not necessa2 ily need to be coYered to gain the expanded fi~ctionality pr~ided by the moveable housing porti~n. An : example of a radiotelephone that has~a moveable housing ' ~

Another unique feature of the wire1ess somIIlunication de~rice 10 as shown in FIGs. 1 and 2 is a substD~nti y . .' transparent portion 50, hereinafter called a lens, coup~ed to ~ ' -35 the first 12 and ~second 14 housing portions. Since the display . ,.
. ~'"'' '~',,'' WO 9d,/130S8 ~ ~ ~, 7 r~ 6 S PCT/US93111291 4~ is at least partia1~y covered by the first housing portion 12 when the first housing portion 12 is moved to the closed housing position 18~ the display traditionally becomes of little use. Howe~er, the lens 50 is coupled to the first 12 and second 14 housing portions such that the lens is disposed essentially opposite at least a portion of the display 46 when the first 12 and second 14 housing portions are moved to the slosed housing position 18. Thus, the display capability is expanded ~;
since it can now be used when the housing portions are in their closed position 18. Of course, the lens may optionally be coupled to only one of the moveable housing portions if so desired. In accordance with the previously taught expanded ~-~
keypad feature, the covered display 46 provides paging information when the housing portions are moved to their ~;
respective closed housing position 18 and radiotelephone information when the housing portions are rnvved to their respective open 20 hou~ingposition.
-~; .
Still another unique feature of thP wireless ~:
:; 20 communication device 10 as shown in FIGs. 1 and 2 is keycap : '~
means 52 coupled to the second housing portion 14. Since the :: keypad 48 is at least part~ally covered by the second housing portion 14 wh the second housing portion 14 is moved to the closed housing position 18, the keypad 48 traditionally becomes of llttle use. However, th~ keycaps 52 are coupled to the second housirlg portion l4 such that the keycaps S2 are disposed esser t,i~11y opposite at least a portion of the keypad 54 when the second housing portion 14 is moved to the closed housing position 18. The: keycaps 52 are comprised of convenhonal elastomeric material and protrude through the thickness of thei second housing portion 14. The keycaps 52 are coupled to the second houslng portion 14 by sandwiching webbing interconnesting indi~idual keycaps between layers of ~he - second housing portion 14. Thus, the keypacl cap~bility is 35 expanded since it can now be used when the second housing ... ':
....
~ "
portion 14 is in its closed position 18. Of course, additional keycaps may alsn be coupled to the first housing portion 12 if - ~---so desired. In accordance with the prenously taught expanded keypad feature, the covered portion of the keypad 54 pro~rides paging functions when the second housing portion 14 is moved to its closed housing position 18 and radiotelephone functions when the second housing portion 14 is moved to its open housing position 20. :
Yet, still another ~nique feature of the ~reless ~;
communication device 10 as shown in FIGs. 1 and 2 is an antenna 56 coupled to the first housing portion 12. A
tran~ceiver (FIG. 7) is su~stantial~y disposed in the third housing portion 16. The antenna 56 is coupled ~ the transceiver and the first housing portion 12. The antem~a ~6 is -: .
moveable between a first, closed, antenna position desi~nP~ted ~: ~ by re~erence numeral 60 at pocket 58 and a second, open, ~ -antenna po~sition design~ted by reference numeral 62 extended beyond the first housing portion 12. The antenna ~6 is shown to be rotatably coupled to the first housing portion 1~ between anterma positions 60 and 62. The antenna preferably extends beyond the housing portion having the earpiece trarlsducer 26 ~.
such that the antenna extends above a human head.
".
2 5 :~ For the radlote3ephone 10 having the length of the first ~ -housing po~tion l2 approximately equal to the length ofthe third housing portion 16, a conventional antenna extending beyond the third~ housing portion 16 would not re~ch beyond '' the ~ength of the first housing portion 12. ~n this position a ~: ~ 30 shadowing phenomenon reduces the performance of l;he ; I con~entional antenna. However, extending the antPnna 56 : '~
beyond the first, moveable housillg por~on 12 raises the ~ '-antenna 56 ~o an even further extended position away from the ~ -:
radiotelephone lQ and therefore overcomes the shadowing

Referring now to FIGs. 3 and 4, there are shown perspective views of the radiotelephone 10 in an open and closed position, respectively, constructed in accordance with a second pre~erred embodiment of the present invention. The ra~iotelephone 10 is the same as the radiotelephone 10 shown in in FIGs. 1 and 2 and described in the assQciated text with .~-the following two exceptions. Firstly, the first 12 and second 14 ~;
housing portions are slidably coupled to the third housing portion 16 rather than beingrotatably coupled. Secondly, the ~nt,~nn~ 56 iS slidably coupled to the first housing p~rtion 12 ~ -~
rather than being rotatably coupled.
The radiotelephone 10 comprises a housing assembly having first 12, second 14 and ~hird 16 housing portions. The first 12 and secon~ 14 housing portions are each coupled to the ; .
third 16 housing portion. The third housing portion includes a side 32. The f;rst 12 and second 14 housing portions are each ~' moveable between a first, closed position, designated by reference numeral 18 in FIG. 3 as shown in FIG. 4~ and a ~-second, open position, designated by re~rence numeral 20 in ~ :
FIG. 3 as shown in FIG. 3. The first housing portion 12 is moveable between a first housing position 18 at least partially covenng thè side 32 of the third housing portion 16 and a ~ ' 25 ~ ~second housing position 20 at least partially exposing the side 32 of the third housing portion 16.

A Im~que feature of the radiotelephone 10 is readily apparent from ~ewing both FIGs. 3 and 4. The first housing portion 12 has an end portion 22. The second housing portion 14 has an end portion 24 exten-~in~ beyond the end portion 22 of WQ 94/13088 2 ~ c i rJ O ~ PCT~S93/11291 the first housing portion 12 when the first 12 and the second 14 housing portions are moved to their first respective housing positions 18 at least partially covering the side 32 of the third :~ :

first 12 and the second 14 housing portions to at least partially cover the side 32 when the housing portions 12 and 14 are in ~ ~ .
their closed housing position 18.
When the housing portions 12 and 14 are in their closed housing lposihon~ 18, the side 64 of the first hou~ing portion 12 : ~:

. : -The first and second housing portions 12 and 14 are shown to be slidably coupled to opposing guide rails 72 and 74 on the third housing portion 16. Alternatively, only one side of the first and second housing portions 12 and 14 rleed be ~: ' slidably coupled to the third housing portion 16, given a robust ' design. For example, the side 64 ofthe first housing porti~n 12 slidably engages with guide rail 72 of the third h~using :
portion 16 and the side 70 of the second housing portion 14 slidably engages with guide rail 74 of the third h~using portion 16. Thus, absolutely, no ove~lap occurs between any 1~ part ofthe sides of first and secondhousingportions 12 and 14.

In the open housing position 20, the first housing ~:
portion 22 is disposed at an obtuse angle relative to the third housing portion 16, preferably 180~, permitting alignment of the earpiece transducer 26 with a human ear. ~:imil~rly, the 1~ second housing portion 14 is also disposed at an obtuse angle :~

to be slidably coupled to the first housing portion 12 between -antenna positions 60 and 62. The antenna preferably extends beyond the housing portion having the earpiece transducer 26 such that the antenna extends above a human head.
For the radiotelephone 10 having the len~th of the first -~

the length ~ ~he first housing portion 12. In this position the shadowin~ .Ihenomenon reduces the performance Qf the conventional antenna. However, exten~ing the antenna 56 beyond the first, moveable housing portion 12 raises the antenna 56 to an even further extended position away from the r adiotelephone 10 and therefore overcomes the shadowing problem resulting in improved antenna perforrn~nce.

embodiment, one of the first 12 and second 14 housing portions 25~ ~ may:overlap the other such that the first 12 and second 14 housing portions are disposed in di~erent but preferably substantially parallel;planes.
The mo~ement of the first housing portion 12 between .
the ~losed 18~ and open 20 housing positions can be coupled to :
the movement of the second housing portinn 14 between the ' ~

to be slidably coupled to the first housing portion 12 between -antenna positions 60 and 62. The antenna preferably extends beyond the housing portion having the earpiece transducer 26 such that the antenna extends above a human head.
For the radiotelephone 10 having the len~th of the first -~
hous; ng po~tion 12 approximately equal to the length of the -, third housing portion 16, a conventional antenna extending beyond the third housing portion 16 would not reach beyond --~
the length ~ ~he first housing portion 12. In this position the shadowin~ .Ihenomenon reduces the performance Qf the conventional antenna. However, exten~ing the antenna 56 beyond the first, moveable housing portion 12 raises the antenna 56 to an even further extended position away from the r adiotelephone 10 and therefore overcomes the shadowing problem resulting in improved antenna perforrn~nce.
