Abstract

An electrical cord is disclosed that includes a power line for transmitting electric current from one end of the electrical cord to the other end of the electrical cord. The electrical cord also includes a cord identification activator integrated into at least one end of the power line and coupled for data communications through the power line to a cord identification illuminator. The activator includes a signal generator for sending an indication signal to the illuminator through the power line in response to a user'"'"'s activation of the activator. The illuminator illuminates in response to receiving the indication signal from the signal generator.

Claims

1. An electrical cord, comprising:

a power line for transmitting electric current from one end of the electrical cord to the other end of the electrical cord;

a cord identification activator integrated into at least one end of the power line and coupled for data communications through the power line to a cord identification illuminator; and

a signal generator for sending an indication signal to the illuminator through the power line in response to a user'"'"'s activation of the activator and the illuminator illuminating in response to receiving the indication signal from the signal generator.

2. The electrical cord of claim 1, wherein each end of the electrical cord includes at least one cord identification activator and at least one cord identification illuminator, wherein a particular illuminator on one end of the power line is responsive to a corresponding activator on the other end of the power line.

3. The electrical cord of claim 1 further comprising a signal receiver that detects the indication signal transmitted through the power line.

4. The electrical cord of claim 3, wherein the signal receiver uses a power line communication (PLC) protocol to detect the indication signal.

5. The electrical cord of claim 1, wherein the illuminator flashes in response to receiving the indication signal.

6. The electrical cord of claim 1, wherein the activator includes a button.

7. The electrical cord of claim 1, wherein the illuminator includes an LED.

8. An electrical cord identification system, comprising:

at least one cord identification interposer that includes a cord identification activator that attaches to one end of a power line of an electrical cord; and

at least one cord identification interposer that includes a cord identification illuminator that attaches to the other end of the power line;

the cord identification interposer with the activator sending an indication signal to the illuminator through the power line in response to a user'"'"'s activation of the activator and the illuminator illuminating in response to receiving the indication signal.

9. The electrical cord identification system of claim 8, wherein one cord identification interposer attaches to sockets of the power line and the other cord identification interposer attaches to plugs of the power line.

10. The electrical cord identification system of claim 8, wherein the cord identification illuminator includes a signal receiver that detects the indication signal transmitted through the power line.

11. The electrical cord identification system of claim 10, wherein the signal receiver uses a power line communication (PLC) protocol to detect the indication signal.

12. The electrical cord identification system of claim 8, wherein the illuminator flashes in response to receiving the indication signal.

13. The electrical cord identification system of claim 8, wherein the activator includes a button.

14. The electrical cord identification system of claim 8, wherein the illuminator includes an LED.

15. A method of identifying an end of an electrical cord, comprising:

detecting an activation of a cord identification activator;

responsive to detecting activation of the cord identification activator, sending an indication signal from the activator to a cord identification illuminator through a power line of the electrical cord, wherein the activator is coupled to one end of the power line and the illuminator is coupled to the other end of the power line; and

receiving the indication signal at the illuminator; and

responsive to receiving the indication signal, illuminating the illuminator.

16. The method of claim 16, further comprising detecting the indication signal transmitted through the power line.

17. The method of claim 18, wherein a power line communication (PLC) protocol is used to detect the indication signal.

18. The method of claim 16, wherein the illuminator includes an LED.
