Abstract

An interface which effects communication between first and second systems and includes a first arrangement for communicating with the first system using a first protocol and a second arrangement for communicating with the second system using a second protocol. At least one of the arrangements includes a mechanism for effecting wireless communication. In accordance with the invention, a third arrangement is included for translating data received from the first system in accordance with the first protocol into data adapted for the second system in accordance with the second protocol. In the illustrative embodiment, the inventive interface further includes an arrangement for translating data received from the second system in accordance with the second protocol into data adapted for the first system in accordance with the first protocol. In the illustrative embodiment, the second system is a Personal Computer, the first system is a peripheral adapted to be connected to the computer, the first protocol is a Bluetooth protocol and the second protocol is a Universal Serial Bus (USB) protocol. In the illustrative embodiment, the inventive interface leverages Universal Serial Bus technology, particularly “plug and play” capability, to simplify the installation and use of Bluetooth-enabled peripherals.

Claims

1. An interface unit for effecting communication between a device and an electronic system, the interface unit comprising:

a device communication module that communicates with the device over a wireless link in accordance with a first protocol;

a system communication module that communicates with the electronic system using a second protocol; and

a translation unit, operatively connected to the device communication module and to the system communication module, that translates data received from the device in accordance with the first protocol into translated data adapted for the electronic system in accordance with the second protocol,

wherein the system communication module comprises a Universal Serial Bus (USB) protocol stack, the interface unit comprising a USB interface operatively connected to the USB protocol stack, and

wherein the system communication module comprises a USB multiplexing and demultiplexing arrangement operatively connected to the translation unit and to the USB protocol stack.

2. The interface unit of claim 1 wherein the translation unit is operative to translate information received from the electronic system in accordance with the second protocol into translated information adapted for the device in accordance with the first protocol.

3. The interface unit of claim 1 wherein the electronic system comprises a personal computer and the second protocol is a USB protocol, the interface unit being connected to a USB port of the personal computer.

4. The interface unit of claim 1 wherein the device communication module comprises a peripheral detection and connection module.

5. The interface unit of claim 4 comprising a Bluetooth interface operatively connected to the peripheral detection and connection module, the communication module comprising a Bluetooth protocol stack operatively connected to the Bluetooth interface.

6. The interface unit of claim 1 wherein the communication module comprises a Bluetooth multiplexing/demultiplexing arrangement operatively connected to the translation unit.

7. The interface unit of claim 1 wherein the system communication module comprises a configuration database operatively connected to the USB multiplexing and demultiplexing arrangement.

8. The interface unit of claim 1 wherein the first protocol comprises the Bluetooth protocol and the second protocol comprises the USB protocol, the translation unit being operative to translate information received from the electronic system in accordance with the USB protocol into translated information adapted for the device in accordance with the Bluetooth protocol.

9. A system for effecting communication with a device over a wireless link in accordance with a first protocol, the system comprising:

a personal computer having an interface compliant with a second protocol; and

an interface unit in communication with the personal computer through the interface, the interface unit comprising;

a device communication module that transmits information to, and receiving data from, the device in accordance with the first protocol;

a system communication module that communicates with the personal computer using a second protocol; and

a translation unit, operatively connected to the device communication module and to the system communication module, that translates the data received from the device in accordance with the first protocol into translated data adapted for the electronic system in accordance with the second protocol,

wherein the interface unit runs emulation software that spoofs a connection as if the interface unit was not acting as an intermediary from the perspective of the personal computer.

10. The system of claim 9 wherein the translation unit is operative to translate information received from the electronic system in accordance with the second protocol into translated information adapted for the device in accordance with the first protocol.

11. The system of claim 9 wherein the second protocol is a Universal Serial Bus (USB) protocol, the interface comprising a USB port of the personal computer.

12. The system of claim 9 wherein the device communication module comprises a peripheral detection and connection module.

13. The system of claim 12 comprising a Bluetooth interface operatively connected to the peripheral detection and connection module, the communication module comprising a Bluetooth protocol stack operatively connected to the Bluetooth interface.

14. The system of claim 9 wherein the communication module comprises a Bluetooth multiplexing and demultiplexing arrangement operatively connected to the translation unit.

15. The system of claim 9 wherein the system communication module comprises a USB protocol stack, the interface unit comprising a USB interface operatively connected to the USB protocol stack.

16. The system of claim 15 wherein the system communication module comprises a USB multiplexing and demultiplexing arrangement operatively connected to the translation unit and to the USB protocol stack.
