Abstract

Certain exemplary embodiments can provide a system, which can comprise a circuit adapted to cause an actuation of an output device according to a control output. The control output can be generated comprising a control signal, the control signal extracted from a sequence of clock pulses. The sequence of clock pulses can comprise the control signal.

Claims (42)

1. A system comprising:

a circuit adapted to cause an actuation of an output device according to a control output, said control output generated comprising a control signal in a low state, said control signal extracted from a sequence of N clock pulses, said sequence containing said control signal, said sequence received across a clock signal isolation boundary of a programmable logic controller, said sequence outputted from said circuit via a serially coupled pair of inverters.

2. The system of claim 1 , wherein:

said control signal is embedded in said sequence of N clock pulses.

3. The system of claim 1 , wherein:

said sequence of N clock pulses is buffered.

4. The system of claim 1 , wherein:

said received sequence is combined with information received from a pulse detector.

5. The system of claim 1 , wherein:

said received sequence is combined with information received from an Extended Pulse Low Detector.

6. The system of claim 1 , wherein:

said control signal is a latch signal.

7. The system of claim 1 , wherein:

N equals 16.

8. The system of claim 1 , wherein:

said control signal is extracted utilizing combinatorial logic.

9. A method comprising:

causing an actuation of an output device according to a control output, said control output generated comprising a control signal in a low state, said control signal extracted from a sequence of N clock pulses, said sequence containing said control signal, said sequence received across a clock signal isolation boundary of a programmable logic controller, said sequence outputted from said circuit via a serially coupled pair of inverters.

10. The method of claim 9 , further comprising:

receiving said sequence.

11. Said method of claim 9 , further comprising:

extracting said control signal from said sequence.

12. The method of claim 9 , further comprising:

generating said control output.

13. The method of claim 9 , further comprising:

embedding said control signal in said sequence of N clock pulses.

14. The method of claim 9 , further comprising:

buffering said sequence of N clock pulses.

15. The method of claim 9 , further comprising:

combining said received sequence with information received from a pulse detector.

16. The method of claim 9 , further comprising:

combining said received sequence with information received from an Extended Pulse Low Detector.

17. The method of claim 9 , further comprising:

said control signal is a latch signal.

18. The method of claim 9 , further comprising:

N equals 16.

19. The method of claim 9 , further comprising:

said control signal is extracted utilizing combinatorial logic.

20. The method of claim 9 , further comprising:

said control signal is extracted utilizing a microprocessor.

21. A machine-readable medium comprising machine-implementable instructions for activities comprising:

causing an actuation of an output device according to a control output, the control output generated comprising a control signal in a low state, the control signal extracted from a sequence of N clock pulses, the sequence containing the control signal, the sequence received across a clock signal isolation boundary of a programmable logic controller, said sequence outputted from said circuit via a serially coupled pair of inverters.
