Abstract
Abstract The invention relates to a modular system for personal data acquisition and communication, advantageously a cellular telephone system the functions of which can be increased by means of various expansion cards. A host device in the system according to the invention, such as a mobile communication device, need not be equipped with all possible functions in the manufacturing stage but some of the functions can be realized on expansion cards, and the user can add a desired function to the host device according to need. The expansion cards are small and they are installed substantially inside the host device, such as a mobile communication device, so that the entity formed by the host device and the expansion card seems to the user as a single compact device. Advantageously, the expansion cards include, in addition to the hardware needed, also the software required for controlling the operation of the modules.

Claims Analysis
Total Claims: 12
Claim 1
Independent Claim
109 words
A system for communication and data processing comprising a portable host
device the functions of which can be controlled by means of a control unit in the
host device, characterized in that the host device comprises at least one connector
socket for expansion cards and that the system further comprises at least one
expansion card in order to add an additional function in the function selection of the
host device; and in that the elements required to realize said additional function and the control
program required to control said elements are implemented in connection with the
expansion card, said control program being adapted for execution by said host
device.
Claim 2
Dependent Claim
20 words
The system of claim 1, characterized in that said expansion card is adapted to
be installed inside the host device
Claim 3
Dependent Claim
52 words
The system of claim 1 or 2, characterized in that said expansion card
comprises more than one control program for connection to host devices of various
types and the host device is designed to use that particular version of the expansion
card control programs which is adapted to that particular host device.
Claim 4
Dependent Claim
36 words
The system of claim 1 or 2, characterized in that it comprises a digital camera
fitted on an expansion card, which digital camera comprises in addition to an
expansion card (10) also an optical unit (65).
Claim 5
Dependent Claim
29 words
The system of claim 4, characterized in that the host device is arranged to
store the pictures produced by said digital camera (10, 65) in the host device's
memory.
Claim 6
Dependent Claim
36 words
The system of claim 4, characterized in that the host device is arranged to
store the pictures produced by said digital camera (10, 65) in the memory of the
expansion card of the digital camera (10).
Claim 7
Dependent Claim
16 words
The system of claim 1, characterized in that the host device comprises a
cellular telephone unit.
Claim 8
Dependent Claim
21 words
The system of claim 1, characterized in that the expansion card is an expansion
card complying with the Miniature Card standard.
Claim 9
Dependent Claim
80 words
An expansion card which can be fitted to a connector socket found in connection
with a portable device designed especially for personal communication, characterized in that an additional function is fitted on the expansion card in order
to make the functions of said device more versatile, and the hardware required to
realize said additional function is fitted on said expansion card, and a memory
element for storing the software required for controlling the hardware is fitted on
said expansion card.
Claim 10
Dependent Claim
44 words
The expansion card of claim 9, characterized in that a digital camera is fitted
on the expansion card, said camera comprising a picture-sensing element (66), an
optical unit (65) and a memory element to store the software controlling the
functions of the digital camera.
Claim 11
Dependent Claim
24 words
The expansion card of claim 9, characterized in that said hardware fitted on
the expansion card includes a connector socket (69) for expansion cards.
Claim 12
Dependent Claim
115 words
A portable device for personal communication comprising at least one expansion
card connector socket for connecting expansion cards to the device in order
to make the functions of the device more versatile, characterized in that the device
is arranged to read identification information from an expansion card connected to
the expansion card connector socket and to determine whether said identificaton
information indicates that the expansion card comprises a program needed for
controlling the expansion card, and, if the expansion card identification information
indicates that the expansion card comprises the program needed for controlling the
expansion card, to control the functions of the expansion card by means of said
program needed for controlling the expansion card.
