Abstract

Systems and methods for selectively coupling one of a group of peripherals to a computer. In one embodiment, a USB switch is coupled between a computer and multiple USB peripheral devices. The switch selectively connects the computer to either a single one of the peripherals, or none of the peripherals. The switch employs a microcontroller which receives control signals from the computer and controls a switching mechanism such as a set of multiplexers or relays to connect data lines from the computer to one of the peripheral ports of the switch, while disconnecting the remainder of the peripheral ports. The switch may also disconnect all of the peripheral ports. The switch may also incorporate a display which is controlled by the switch'"'"'s microcontroller. One or more power sources may be included to provide power to each of the peripheral ports.

Claims

1. A system comprising:

a data port;

a plurality of peripheral device ports; and

a switch configured to selectively connect the data port to no more than one of the peripheral device ports.

2. The system of claim 1,

further comprising

a processor coupled to the switch and configured to control the switch,

a display coupled to the processor and configured to display information provided by the processor,

a control port configured to connect the system to a computer, and

one or more power supplies connected to the peripheral ports and

configured to provide power to the peripheral ports;

wherein

the data port comprises a USB port configured to connect the system to the computer, and

the peripheral device ports comprise USB ports configured to connect the system to corresponding USB peripheral devices.

3. The system of claim 1, further comprising a control port which is separate from the data port.

4. The system of claim 3, wherein the control port comprises an RS-232 port configured to connect the system to a computer.

5. The system of claim 1, further comprising a processor which is coupled to the switch and configured to control the switch to selectively connect the data port to no more than one of the USB ports.

6. The system of claim 5, further comprising a display coupled to the processor.

7. The system of claim 1, one or more power supplies connected to the peripheral ports and configured to provide power to the peripheral ports.

8. The system of claim 1, wherein the switch comprises one or more multiplexers.

9. The system of claim 1, wherein the switch comprises one or more relays.

10. The system of claim 1, wherein the switch is configured to alternately connect the data port to a single one of the peripheral device ports or none of the peripheral device ports.

11. The system of claim 1, wherein the data port comprises a USB port configured to connect the system to a computer.

12. The system of claim 1, wherein the peripheral device ports comprise USB ports configured to connect the system to corresponding USB peripheral devices.

13. A method comprising:

providing a data port;

providing a plurality of peripheral device ports; and

selectively connecting the data port to no more than one of the peripheral device ports.

14. The method of claim 13, wherein the data port and the peripheral device ports comprise USB ports.

15. The method of claim 14, further comprising connecting the data port to a computer and connecting each of the USB peripheral device ports to corresponding USB peripheral devices.

16. The method of claim 15, further comprising providing power to each of the USB peripheral device ports from a power source external to the computer.

17. The method of claim 15, executing software on the computer, wherein the software is configured to control the connection of the data port to the peripheral device ports.

18. The method of claim 13, further comprising alternately connecting the data port to a single one of the peripheral device ports or none of the peripheral device ports.

19. The method of claim 13, further comprising displaying to a user status information associated with the connection of the data port to the peripheral device ports.
