Abstract

Systems and methods for detecting states are disclosed. An information handling system may include a processor and a plurality of information handling resources communicatively coupled to the processor via the common control line. The processor may be configured to produce a first signal on a common control line. Each of the plurality of information handling resources may include a tag having a signal threshold, the tag configured to communicate a second signal via the common control line indicating the presence of the particular information handling resource in response to the first signal exceeding the signal threshold of the tag.

Claims (20)

1. An information handling system, comprising:

a processor configured to produce a first signal on a common control line;

a plurality of information handling resources communicatively coupled to the processor via the common control line, each of the plurality of information handling resources including a tag having a signal threshold, the tag configured to communicate a second signal via the common control line indicating the presence of the particular information handling resource in response to the first signal exceeding the signal threshold of the tag; and

a high-pass filter included in the processor, the high-pass filter communicatively coupled to the common control line and configured to produce a pulsed third signal in response to an increase of a magnitude of the second signal, the pulsed third signal indicating the presence of a particular information handling resource of the plurality of information handling resources.

2. An information handling system according to claim 1 , wherein the first signal comprises a voltage signal.

3. An information handling system according to claim 1 , wherein the first signal comprises an approximately linear monotonically increasing signal.

4. An information handling system according to claim 1 , wherein the second signal comprises a current signal.

5. An information handling system according to claim 1 , each tag including a current source, the current source communicatively coupled to the common control line and configured to increase a magnitude of a current of the common control line in response to the first signal exceeding the signal threshold of the tag associated with the particular information handling resource.

6. An information handling system according to claim 1 , wherein the signal threshold is unique to each of the plurality of information handling resources.

7. An information handling system according to claim 1 wherein the tag is configured to identify the particular information handling resource.

8. A method for detecting state, comprising:

producing, by a processor, a first signal on a common control line, the processor including a high-pass filter communicatively coupled to the common control line;

receiving, at an information handling resource of a plurality of information handling resources, the first signal at a tag having a signal threshold, the plurality of information handling resources communicatively coupled to the processor via the common control line;

communicating, by the information handling resource, a second signal from the tag indicating presence of the information handling resource in response to the first signal exceeding the signal threshold; and

producing, by the high-pass filter, a pulsed third signal in response to an increase of a magnitude of the second signal, the pulsed third signal indicating the presence of the information handling resource.

9. A method according to claim 8 , wherein the first signal is received via the common control line and the second signal is communicated via the common control line.

10. A method according to claim 8 , wherein the first signal comprises a voltage signal.

11. A method according to claim 8 , wherein the first signal comprises an approximately linear monotonically increasing signal.

12. A method according to claim 8 , wherein the second signal comprises a current signal.

13. A method according to claim 8 , further comprising increasing a magnitude of a current of the common control line in response to the first signal exceeding the signal threshold.
