Abstract

An apparatus for connecting to a number of peripheral devices has a detection device for detecting coupling of a particular one of the peripheral devices to the apparatus. The detection device has a first magnetic means and the particular one of the peripheral devices has a second magnetic means for cooperating with the first magnetic means. The first and second means form a unique pair for uniquely recognizing the particular one of the peripheral devices among the peripheral devices.

Claims

1. An apparatus for connecting to a particular one of a plurality of different peripheral devices, said apparatus comprising:

a detection device for detecting coupling of said particular one of said plurality of different peripheral devices to said apparatus, said detection device comprising first magnetic means for cooperating with second magnetic means comprised in said particular one of said plurality of different peripheral devices, whereby said first and second magnetic means form a unique pair for uniquely recognizing said particular one of said plurality of different peripheral devices among said plurality of different peripheral devices coupled to said apparatus.

2. An apparatus according to claim 1, wherein said first magnetic means comprises a linear Hall-effect sensor, and said second magnetic means is a single magnet, said unique pair being formed through a given magnet strength for said particular one of said plurality of peripheral devices, magnet strengths of different peripheral devices being different.

3. An apparatus according to claim 1, wherein said first magnetic means comprises a plurality of Hall-effect sensors positioned at different positions within said apparatus, and said second magnetic means comprises at least one magnet positioned in said particular one of said plurality of peripheral devices, said at least one magnet cooperating with a corresponding one of said plurality of Hall-effect sensors when said particular one of said plurality of peripheral devices is coupled to said apparatus, said unique pair being formed through varying the number and position of magnets in said plurality of peripheral devices.

4. An apparatus according to claim 1, wherein said detection device comprises a first analog-to-digital converter that is coupled to said first magnetic means, said first analog-to-digital converter providing a digital identification signal for identifying said particular one of said plurality of peripheral devices.

5. An apparatus according to claim 1, wherein said detection device comprises a second analog-to-digital converter that is coupled to said first magnetic means, said second analog-to- digital converter providing a digital start-of-disconnection signal for said particular one of said plurality of peripheral devices.

6. An apparatus according to claim 1, wherein said first magnetic means and said second magnetic means form a Reed switch.

7. A peripheral device for coupling to an apparatus with a detection device for detecting coupling of said peripheral device to said apparatus, said detection device comprising first magnetic means, and said peripheral device comprising:

second magnetic means for cooperating with said first magnetic means, said first and second magnetic means forming a unique pair for uniquely recognizing said peripheral device among a plurality of different peripheral devices coupleable to said apparatus.

8. A peripheral device as claimed in claim 7, wherein said first magnetic means comprises a linear Hall-effect sensor, and said second magnetic means is a single magnet, said unique pair being formed through a given magnet strength for said peripheral device, magnet strengths of different peripheral devices being different.

9. A peripheral device as claimed in claim 7, wherein said first magnetic means comprises a plurality of Hall-effect sensors positioned at different positions within said apparatus, and said second magnetic means comprises at least one magnet positioned in said peripheral device, said at least one magnet cooperating with a corresponding one of said plurality of Hall-effect sensors when said peripheral device is coupled to said apparatus, said unique pair being formed through varying the number and position of magnets among said plurality of peripheral devices.
