`tween the connectors on the track and connectors on
`the mounting bracket.
`Among the advantages offered by the present inven-
`tion are a reduction in cost of a computer with the
`capabiliy of transmitting data over the cellular tele-
`phone system. Only one cellular portable telephone
`needs to be purchased for a number of computers since
`the cellular portable telephone may be used on any of
`the computers incorporating the present
`invention.
`Each computer will have a reduction in weight since
`the cellular telephone will not be permanently installed
`in the computer. The computer may be used to transmit
`data over a cellular telephone system in the AMPS
`system, the European NORDIC and TACS systems.
`Examples of the more important features and advan-
`tages of the invention have thus been summarized rather
`broadly in order that the following detailed description
`thereof may be better understood and in order that the
`contribution to the art may be better appreciated. There
`are, of course, additional features of the invention that
`will be described hereinafter and which will also form
`the subject of the claims appended hereto. Other_fea-
`tures of the invention will become apparent with refer-
`ence to the following detailed description of a presently
`preferred embodiment thereof in connection with the

`
`BACKGROUND OF THE INVENTION
`
`1. Field of the Invention
`The present invention relates in general to the trans-
`mission and reception of data and voice signals. More
`particularly, but not by way of limitation, it relates to
`apparatus for removably connecting a cellular portable
`telephone to a computer for transmitting and receiving
`data signals to and from the computer via the cellular
`portable telephone.
`2. Description of the Prior Art
`Although this invention is applicable to numerous
`and various types of computers, it has been found par-
`ticularly useful in the environment of laptop or portable
`computers. Therefore, without limiting the applicability
`of the invention to “laptop and/or portable computers”,
`the invention will be described in such environment.
`In recent years, with the increased emphasis on and
`use of portable or laptop computers and the availability
`of the cellular telephone system, more and more people
`are finding the need for and the desirability of combin-
`ing the portable or laptop computer with the cellular
`telephone system to not only send voice signals back
`and forth but to send digital data back and forth be-
`tween remote sites.
`
`Laptop or portable computers are now available
`which have a cellular telephone unit or system built
`inside (in a permanent type installation) the housing of
`the laptop or portable computers for use in sending data
`and voice signals over the cellular telephone system
`from and to remote locations where telephone lines are
`not available.
`
`The present invention is intended to provide a solu-
`tion to various prior art deficiencies which include the
`increased weight added to the computer by the built-in
`cellular telephone system and the added cost of having
`a built-in cellular telephone system in each computer.

`ture or cavity 18 formed in the generally planar upper
`surface of housing 20 of computer 22. First electrical
`connector 14 is positioned at the end of the first end
`portion 24 of track 12. Second electrical connector 16 is
`positioned at the end of the second end portion 26 of
`track 12. Track 12 includes a base portion 28 of prede-
`termined width and length and having a generally pla-
`nar upper surface 30. Extending outwardly from the
`base portion 28 in a cantilever manner along the length
`of the base portion 28 is a first edge portion 32. Extend-
`ing outwardly from the base portion 28 in a cantilever
`manner along the length of the base portion 28 and
`positioned opposite the first edge portion 32 is a second
`edge portion 34. Cover 36 is structured and dimen-
`sioned to fit into aperture or cavity 18, when a cellular
`portable telephone 38 is not removably mounted or
`connected to computer 22, such that the top surface of
`cover 36 is flush with housing 20. Tabs 40 on the end of
`cover 36 fit into openings 42 in housing 20.
`Cellular portable telephone 38 is manufactured by
`and commercially available from Motorola,
`Inc. of
`Schaumberg, Illinois. Back surface 44 contains a track
`46 which slidably mates and mounts onto track 12.
`Connector 48 mates with and operatively connects to
`first electrical connector 14 while connector 50 mates
`
`with and operatively connects to second electrical con-
`nector 16 when cellular portable telephone 38 is slid-
`ably mounted onto track 12. Back surface 44 of of cellu-
`lar portable telephone 38 is offset from track 46 a suffi-
`cient distance to allow track 46 and track 12 to opera-
`tively engage and connect. Cellular portable telephone
`38 is shown with the battery pack (not shown) re-
`moved. Cellular portable telephone 38 slidably con-
`nects or mounts to the battery pack (not shown) in a
`manner similar to the way in which it connects or
`mounts to apparatus for removably connecting 10 in-
`corporated into computer 22. Cellular portable tele-
`phone 38 meets the AMPS (Advanced Mobile Phone
`Service) specifications determined by the Federal Com-
`munications Commission.
`With further reference to FIG. 1, track 12, first edge
`portion 32 and second edge portion 34 are approxi-
`mately 5.65 inches (approximately 143.5 mm) in length.
`First edge portion 32 and second edge portion 34 extend
`outwardly from base portion 28 at least approximately
`0.04 inches (approximately 1 mm). The measurement
`between the outermost edges of first edge portion 32
`and second edge portion 34 is approximately 1.4 inches
`(approximately 35.5 mm). It will be appreciated that a
`void is provided in the center area of first electrical
`connector 14 to accomodate a portion 52 of antenna 54.
`With reference to FIG. 2, cellular portable telephone
`38 (available from Motorola, Inc.) is shown being slid-
`ably mounted in the apparatus for removably connect-
`ing 10. It will be appreciated that to be fully mounted
`and in an operational position, cellular portable tele-
`phone 38 must be completely slid into aperture 18 to fill
`same and make operational connection of the mating
`connectors.
`
`With reference to FIG. 3, apparatus for removably
`connecting 10 is more clearly shown as incorporated
`into computer 22.
`With reference to FIG. 4, the section taken through
`track 12 more clearly shows the relationship between
`the first edge portion 32, the second edge portion 34, the
`generally planar upper surface 30 of base portion 28 and
`the sidewalls 56 of aperture or cavity 18 of the invention
`as incorporated into housing 20 of computer 22.

`With reference to FIG. 5, an end view of cellular
`portable telephone 38, as installed in the apparatus for
`removably connecting 10 in an operational position, is
`shown.
`Illustrated in FIG. 6 is an enlarged view of the rela-
`tionship of track 12 and first edge portion 32 with track
`46 of cellular portable telephone 38 when the cellular
`portable telephone 38 is operatively mounted to the
`apparatus for removably connecting 10. It will be ap-
`preciated that cellular portable telephone 38 can only be
`removed by sliding the cellular portable telephone 38
`outwardly away from housing 20 of computer 22.
`Illustrated in FIG. 7 is mounting bracket 58 which
`when used with the apparatus for removably connect-
`ing l0 allows the use of cellular portable telephones for
`other systems (AMPS, European TACS and NORDIC
`systems) and other manufactures of cellular portable
`telephones (in addition to Motorola, Inc.) such as NEC
`and OKI. Motorola manufactures cellular portable tele-
`phones which operate on the AMPS, the European
`TACS and NORDIC systems and all of which will
`interface directly with the apparatus for removably
`connecting 10. Cellular portable telephones manufac-
`tured by NEC and OKI require an adapter in the form
`of mounting bracket 58 to interface and operatively
`connect with the apparatus for removably connecting
`10.
`
`Mounting bracket 58 comprises a first side 60 which
`is configured like the back of the cellular portable tele-
`phone 38 from Motorola, Inc. and will slidably connect
`and mount on the apparatus for removably connecting
`10. Second side 62 is opposite first side 60 and includes
`back wall 64. Back wall 64 includes a top portion 66, a
`bottom portion 68, a first wall 70 and a second wall 72
`positioned on opposing edges of back wall 64 and pro-
`jecting therefrom at generally right angles. A front wall
`74 is positioned at the bottom portion 68 and is con-
`nected between the first wall 70 and second wall 72. A
`floor portion 76 is connected between the back wall 64,
`the first wall 70 and the second wall 72. Third electrical
`connector 78 is mounted in floor portion 76 and is con-
`figured to interface and connect with the electrical
`connector on the bottom of the cellular portable tele-
`phone 80 available from NEC. Bottom portion 68 of
`back wall 64, first wall 70, second wall 72 and floor
`portion 76 cooperate to form a cavity or housing to
`hold and support cellular portable telephone 80.
`In an additional embodiment of mounting bracket 58,
`a fourth electrical connector 82 is mounted in the bot-
`tom portion 68 of back wall 64 and is positioned and
`configured to interface and connect with the connector
`on the back of a cellular portable telephone available
`from OKI.
`
`When a cellular portable telephone from either NEC
`or OKI is to be used with the apparatus for removably
`connecting 10,
`that particular cellular portable tele-
`phone is slipped into a mounting bracket 58 which is
`configured for that particular cellular portable tele-
`phone. Then that particular mounting bracket 58 is
`slidably mounted to the apparatus for removably con-
`necting 10 (and track 12).
`Illustrated in FIG. 8 are the electrical connection and
`conventional cellular signals routed between first elec-
`trical connector 14 of the apparatus for removably con-
`necting (or mounting track) 10 and data interface 86
`over cable leads 84. Data interfaces of this type are
`known,‘ commercially available items, as exemplified by
`the interfaces sold by Motorola, Inc. The outputs of

`data interface 86 over leads 88 and 90 to modem 92
`installed in computer 22 comprise the conventional
`signals on the tip and ring leads.
`Illustrated in FIG. 9 are the electrical connection and
`
`conventional cellular signals routed between cellular
`portable telephone 80 and the apparatus for removably
`connecting (or mounting track) 10 through the cellular
`interface circuitry 94 which is physically mounted be-
`tween the first side 60 and the second side 62 (see FIG.
`7) of mounting bracket 58. Cellular interface circuitry
`94 is operatively connected between the connector
`(which mates with first electrical connetor 14 - see FIG.
`1) on the first side 60 of mounting bracket 58 and either
`the third electrical connector 78 in the configuration of
`the mounting bracket 58 for an NEC cellular portable
`telephone or the fourth electrical connector 82 in the
`configuration of the mounting bracket 58 for an OKI
`cellular portable telephone. Cellular interface circuitry
`94 comprises conventional signal conditioning circuits
`and cross wiring between various pins of the connectors
`of mounting bracket 58 such that the proper signals will
`appear on the correct leads in cable leads'84 and the
`correct pins of third electrical connector 78 and fourth
`electrical connector 82.
`
`Thus, it is apparent that there has been provided in
`accordance with this invention, apparatus that substan-
`tially incorporates the advantages setmforth above and
`reduces the weight of the computer by allowing the
`weight of the cellular telephone to be removed from the
`computer until it is desired to send data over the cellular
`telephone system. The cost of providing the capability
`of sending data over the cellular telephone system has
`been reduced by eliminating the need to permanently
`install a cellular telephone in each computer. Using the
`present invention, a person may use the same computer
`in the U.S. and in Europe and transmit data over differ-
`ent cellular systems in each country. All that need be
`known is where the computer will be used and the
`correct cellular portable telephone can be supplied for
`use with the invention (including the correct mounting
`bracket) or all three type cellular phones may be sup-
`plied and used where the different cellular systems are
`found.
`Although the present invention has been described
`herein with reference to specific forms thereof, it is
`evident that many alternatives, modifications and varia-
`tions will become apparent to those skilled in the art in
`light of the foregoing disclosure. Accordingly,
`this
`description is to be construed as illustrative only and is
`for the purpose of teaching those skilled in the art the
`manner of carrying out the invention. It is to be under-
`stood that the forms of the invention herewith shown
`and described are to be taken as presently preferred
`embodiments. Various changes may be made in the
`shape, size and arrangement of parts. For example,
`equivalent elements may be substituted for those illus-
`trated and described herein, parts may be reversed, and
`certain features of the invention may be utilized inde-
`pendently of other features of the invention. It will be
`appreciated that various modifications, alternatives,
`variations, etc., may be made without departing from
`the spirit and scope of the invention as defined by the
`appended claims.
