Abstract

Systems and methods to distribute power to individual power outlets are disclosed. A particular apparatus includes a memory having program code and a processor configured to access the memory and execute the program code to determine whether to allow power to be supplied to an individual power outlet. In one implementation, the determination is based on a current draw and a resistance reading associated with the power outlet.

First claim

The invention claimed is:

1. An apparatus comprising:
a memory storing program code; and
a processor configured to access the memory and execute the program code to:
determine to allow power to be supplied to a first power outlet based on a first determination that there is no current draw present at the first power outlet and a second determination that there is an increase in resistance at the first power outlet; and
while allowing power to be supplied to the first power outlet, determine to turn off power to a second power outlet based on a third determination that there is no current draw present at the second power outlet and a fourth determination that a resistance at the second power outlet has remained constant.

2. The apparatus of claim 1 , wherein the power is supplied to the second power outlet when a current draw is detected at the second power outlet.

3. The apparatus of claim 1 , wherein the power is supplied to the second power outlet when a resistance at the second power outlet increases.

4. The apparatus of claim 1 , wherein the processor is configured to determine the resistance at the second outlet from an ohmmeter at the second power outlet.

5. The apparatus of claim 1 , wherein the processor is configured to determine the current draw at the second power outlet from an ammeter at the second power outlet.

6. The apparatus of claim 1 , wherein the processor is housed proximate to the second power outlet.

7. The apparatus of claim 1 , wherein the processor is remote from the second power outlet.

8. The apparatus of claim 1 , wherein the processor communicates wirelessly with a sensor of the second power outlet.

9. The apparatus of claim 1 , wherein the memory includes a profile associated with an electrical characteristic of a device plugged into the second power outlet.

10. The apparatus of claim 1 , wherein the processor is configured to generate a profile associated with an electrical characteristic of a device plugged into the second power outlet.

11. A method of selectively distributing power to outlets, the method comprising:
determining a current draw at first and second power outlets;
determining a resistance at the first and second power outlets; and
while allowing power to be supplied to the first power outlet, determining to turn off power to the second power outlet based on a determination that there is no current draw at the second power outlet and a determination that the resistance at the second power outlet has remained constant.

12. The method of claim 11 , further comprising allowing power to the second power outlet when the resistance at the second power outlet has increased.

13. The method of claim 11 , wherein the resistance at the second power outlet is determined from an ohmmeter at the second power outlet.

14. The method of claim 11 , wherein the current draw at the second power outlet is determined from an ammeter at the second power outlet.

15. The method of claim 11 , the first and second power outlets are part of a power strip having power supplies that are separately regulated.

16. A non-transitory computer readable storage medium, to generate a cognitive model, comprising: a computer readable program code embodied therewith, the computer readable program code being executable by a processor to determine a current draw at first and second power outlets a power outlet, determine a resistance at the first and second power outlets, and while allowing power to be supplied to the first power outlet, determine to turn off power to the second power outlet based on a determination that there is no current draw at the second power outlet and a determination that the resistance at the second power outlet has remained constant.
