Abstract

A backup power system is disclosed which has a first port in communication with a server. The server includes first and second ports, and the backup power system is in communication with the second port of the server and receives a first voltage signal from the second port of the server. A second communications port of the system is in communication with a peripheral. The peripheral is powered by a separate connection to the first port of the server. A controller of the system detects when power being provided by the server through the server'"'"'s second port has dropped below a threshold level. A power storage component responsive to the controller supplies power to the peripheral when the power provided from the server'"'"'s second port drops below the threshold level.

Claims

1. A backup power system comprising:

a first port in communication with a server, the server including first and second ports, the backup power system being in communication with the second port of the server and receiving power from the second port of the server, and where the server'"'"'s first and second ports put out the same power output;

a second communications port in communication with a peripheral, the peripheral adapted to be powered by a separate connection to the first port of the server;

a controller for detecting when power being provided by the server through the power from the server'"'"'s second port has dropped below a threshold level; and

a power storage component responsive to the controller for supplying power to the peripheral when the power being provided from the server'"'"'s second port drops below the threshold level.

2. The system of claim 1, wherein the controller is configured to determine when power being received from the server has risen above the threshold level, and to remove power from the supercapacitor when the power being output from the first and second ports of the server rises above the threshold level.

3. The system of claim 1, further comprising a voltage regulator for regulating the power provided by the power storage component.

4. The system of claim 1, wherein the power storage component comprises a supercapacitor.

5. The system of claim 1, wherein the power storage component comprises a rechargeable battery.

6. The system of claim 1, wherein the controller comprises a voltage measurement subsystem for monitoring a voltage output from the server'"'"'s second port.

7. The system of claim 1, wherein the controller further comprises a voltage regulator for regulating power being supplied to the peripheral by the system.

8. The system of claim 1, wherein the first and second ports of the server comprise universal serial bus (USB) ports, and wherein the first communications port of the system comprises a USB port.

9. The system of claim 8, wherein the second communications port comprises a USB port.

10. The system of claim 1, wherein the second communications port comprises a DC power out port.

11. The system of claim 1, further comprising a display component for displaying an operating status of the system.

12. The system of claim 11, wherein the display component comprises at least one light emitting diode (LED).

13. The system of claim 12, further comprising a blinker circuit for controlling operation of the LED.

14. The system of claim 11, wherein the display component comprises a liquid crystal display (LCD).

15. The system of claim 1, wherein:

the first and second ports of the server comprise universal serial bus (USB) ports;

the first and second ports of the system comprise USB ports; and

the peripheral includes first and second ports which each comprise USB ports.

16. A backup power system adapted to be coupled in communication with a second universal serial bus (USB) port of a server and a port of a peripheral, and wherein the peripheral also has a first USB port coupled to a first USB port of the server, the system comprising:

a controller;

a voltage measurement subsystem for monitoring power received from the second USB port of the server;

a power storage component;

a port in communication with the port of the peripheral; and

the controller configured to use the voltage measurement subsystem to detect when power being supplied from the second USB port of the server drops below a predetermined threshold, and to cause the power storage component to apply power to the port of the peripheral to power the peripheral.

17. The system of claim 16, wherein the port of the system comprises a second USB port, and the port of the peripheral comprises a second USB port.

18. The system of claim 16, wherein the port of the system comprises a DC power output port, and the port on the peripheral comprises a DC Power In port.

19. A method for monitoring and providing backup power to a peripheral which is communicating with, and receiving primary power from, a first communications port of a server, the method comprising:

monitoring power being output from a second communications port of the server, where the first and second communications ports of the server are providing the same power output;

using a controller and a voltage monitoring subsystem to detect when power being output from the second communications port of the server drops below a predefined threshold level; and

when the power being output from the server'"'"'s communications ports drops below the predefined threshold, using the controller to control a power storage component to apply backup power to the peripheral.

20. The method of claim 19, wherein using the controller to control a power storage component comprises using the controller to control a supercapacitor to cause the supercapacitor to apply the backup power to the peripheral.
