Abstract
Abstract An adapter for a cellular mobile phone unit which converts the unit to permit simultaneous insertion of a plurality of telephone numbers. A main circuit board is coupled to a microprocessor of the unit, which board includes a plurality of number assignment modules, or NAM's (ROM's), each NAM having its own unique telephone number code. The NAM's are connected such that fifteen of the sixteen pin-connections of each NAM are correspondingly and respectively connected in series, for coupling to the fifteen pin-connections of a plug at one end of a ribbon cable, the other end of the ribbon cable being coupled to the microprocessor of the unit via the conventional NAM connection therefor. Each remaining pin of each NAM, which is not connected in series, is connected to a unique stop of a multi-position switch, so that a selected one of the NAM's may be coupled to the microprocessor in order to change the telephone number from one to another. A secondary relay printed circuit board may also be provided to allow for remote switching from one NAM to another. The principles are also applicable to a personal computer's expansion slots, where a plurality of dedicated ROM chips may be selectively accessed by the microprocessor via the same address location.

Claims Analysis
Total Claims: 8
Claim 1
Independent Claim
83 words
A method of using a cellular mobile telephone unit, which cellular mobile phone telephone comprises a microprocessor, comprising: (a) simultaneously providing at least first and a second distinct user telephone numbers in a memory means; (b) selecting one of the at least first and second distinct user telephone numbers to be used for making an outgoing call based thereon; (c) said step (b) comprising coupling the selected one of the distinct user telephone numbers to the microprocessor of the cellular mobile telephone unit.
Claim 2
Independent Claim
83 words
A method of using a cellular mobile telephone unit, which cellular mobile phone telephone comprises a microprocessor, comprising: (a) simultaneously providing at least first and a second distinct user telephone numbers in a memory means; (b) selecting one of the at least first and second distinct user telephone numbers to be used for making an outgoing call based thereon; (c) said step (b) comprising coupling the selected one of the distinct user telephone numbers to the microprocessor of the cellular mobile telephone unit.
Claim 3
Dependent Claim
41 words
The method according to claim 1, further comprising repeating said steps (a), (b) and (c) a plurality of times so as to make an outgoing call based on the first telephone number and the second telephone call on another telephone number.
Claim 4
Dependent Claim
33 words
The method according to claim 1, wherein said step (b) comprises making an outgoing call on a first cellular mobile phone system, and making an outgoing call on another cellular mobile phone system.
Claim 5
Dependent Claim
27 words
The method according to claim 1, wherein said step (c) comprises manually switching the selected distinct telephone number to the microprocessor of the cellular mobile telephone unit.
Claim 6
Independent Claim
189 words
A method of using a cellular mobile telephone unit, which cellular mobile telephone unit comprises a microprocessor, comprising: (a) simultaneously providing at least two distinct user telephone numbers in a memory means, whereby the microprocessor of the cellular mobile telephone unit may access any one of the distinct telephone numbers; (b) selecting one of the at least two distinct user telephone numbers, said step of selecting comprising selectively and exclusively coupling one of the at least two distinct user telephone numbers to the microprocessor; (c) receiving an incoming call on the selected one of at least two distinct user telephone numbers; (d) switching over to another distinct user telephone number, said step of switching over comprising coupling the microprocessor of the cellular mobile telephone unit to the memory means storing therein the representation of said another distinct telephone number, said step further comprising simultaneously decoupling a portion of the memory means storing therein the representation of the one distinct user telephone number previously coupled to the microprocessor during said step (b); and (e) receiving an incoming call via said another distinct user telephone number provided via said step (d).
Claim 7
Independent Claim
189 words
A method of using a cellular mobile telephone unit, which cellular mobile telephone unit comprises a microprocessor, comprising: (a) simultaneously providing at least two distinct user telephone numbers in a memory means, whereby the microprocessor of the cellular mobile telephone unit may access any one of the distinct telephone numbers; (b) selecting one of the at least two distinct user telephone numbers, said step of selecting comprising selectively and exclusively coupling one of the at least two distinct user telephone numbers to the microprocessor; (c) receiving an incoming call on the selected one of at least two distinct user telephone numbers; (d) switching over to another distinct user telephone number, said step of switching over comprising coupling the microprocessor of the cellular mobile telephone unit to the memory means storing therein the representation of said another distinct telephone number, said step further comprising simultaneously decoupling a portion of the memory means storing therein the representation of the one distinct user telephone number previously coupled to the microprocessor during said step (b); and (e) receiving an incoming call via said another distinct user telephone number provided via said step (d).
Claim 8
Dependent Claim
40 words
The method according to claim 5, wherein said step (e) comprises receiving an incoming call via a different cellular mobile phone system, as compared to the cellular mobile phone system by which the incoming was received during said step (c).
