Abstract

A docking station for a portable computer includes a wireless transceiver for wireless communication with the portable computer. The docking station also includes a plurality of ports. Each port includes a physical connector for connection to, for example, one or more peripheral devices, a network or a monitor. A translation manager within the docking station manages translation of information transferred between the wireless transceiver and the plurality of ports.

a plurality of ports, each port including a physical connector, and

a second translation manager, coupled between the second wireless transceiver and the plurality of ports, for managing translation of information transferred between the second wireless transceiver and the plurality of ports.

5. A portable computing system as in claim 4 wherein the second wireless transceiver transmits and receives infrared signals.

6. A portable computing system as in claim 4 wherein the second translation manager includes:

a second protocol manager coupled to the second wireless transceiver, the second protocol manager extracting different information intended for the plurality of ports from wireless communication received by the second wireless transceiver; and

,

a port generator coupled to the plurality of ports and to the second protocol manager, the port generator generating control and data signals for the plurality of ports.

7. A portable computing system as in claim 6:

wherein the docking station additionally includes a port for an input/output bus interface; and

wherein the second translation manager additionally includes a bus generator which generates control and data signals for the input/output bus interface.

8. A portable computing system as in claim 7 additionally comprising:

an optical cable for connecting the docking station to the portable computer.

9. A portable computing system as in claim 7 wherein the docking station additionally comprises a flat pad on which is placed the portable computer.

10. A portable computing system as in claim 9 wherein the flat pad includes an infrared transceiver.

11. A portable computing system as in claim 10 wherein the flat pad additionally includes a low profile inductor used to provide power to the portable computer.

12. A portable computing system as in claim 9 wherein the flat pad is built into a work surface.

13. A portable computing system as in claim 9 wherein the docking station additionally comprises an alarm means for detecting when the portable computer has been removed from the flat pad without authorization.

14. A portable computing system as in claim 4 wherein the docking station additionally includes:

a window on a first side of the docking station; and

,

a reflective surface behind the window;

wherein the wireless transceiver transmits and receives infrared signals which travel through the window and are reflected by the reflective surface.

15. A docking station for a portable computer comprising:

a wireless transceiver for wireless communication with the portable computer;

a plurality of ports, each port including a physical connector; and

,

a translation manager, coupled between the wireless transceiver and the plurality of ports, for managing translation of information transferred between the wireless transceiver and the plurality of ports, wherein the translation provided by the translation manager allows the plurality of ports to fully function as ports of the portable computer while using only the wireless transceiver for data communication between the docking station and the portable computer.

16. A docking station as in claim 15 wherein the wireless transceiver transmits and receives infrared signals.

17. A docking station as in claim 15 wherein the translation manager includes:

a protocol manager coupled to the wireless transceiver, the protocol manager extracting data intended for the plurality of ports from wireless communication received by the wireless transceiver; and

,

a port generator coupled to the plurality of ports and to the protocol manager, the port generator generating control and data signals for the plurality of ports from the data extracted by the protocol manager.

18. A docking station as in claim 17,

wherein the docking station additionally includes a port for an input/output bus interface, and
