Abstract

A method for discovering a power level in a diode discovery circuit includes transmiting a pulse signal from a diode discovery device on a first line, receiving the pulse signal in the diode discovery device on a second line, measuring a time to charge a capacitor in response to applying power to determine the power level, and applying power in response to comparing the transmitted pulse signal to the received pulse signal and to measuring the time.

Claims

1. A method for discovering a power level in a diode discovery circuit comprising:

transmitting a pulse signal from a diode discovery device on a first line;

receiving the pulse signal in the diode discovery device on a second line;

measuring a time to charge a capacitor in response to applying power to determine the power level; and

applying power in response to comparing the transmitted pulse signal to the received pulse signal and to measuring the time.

2. The method of claim 1 in which the pulse signal includes a pseudo random generated 11-bit word.

3. The method of claim 2 in which the pseudo random generated 11-bit word is generated by a recursive linear function.

4. The method of claim 3 in which the recursive linear function is X(n)=X[n−

11]+X[n−

9] (modulo 2).

5. The method of claim 2 in which the pseudo random generated 11-bit word is seeded by a port number of the diode discovery device.

6. The method of claim 1 further comprising repeating the transmitting and receiving.

7. A computer program product residing on a computer readable medium having instructions stored thereon which, when executed by the processor, cause the processor to:

transmit a pulse signal from a diode discovery device on a first line;

receive the pulse signal in the diode discovery device on a second line;

measure a time to charge a capacitor in response to applying power to determine the power level; and

apply power in response to comparing the transmitted pulse signal to the received pulse signal and to the measured time.

8. The computer program product of claim 7 in which the pulse signal includes pseudo random generated 11-bit word.

9. The computer program product of claim 8 in which the pseudo random generated 11-bit word is generated by a recursive linear function.

10. The computer program product of claim 9 in which the recursive linear function is X(n)=X[n−

11]+X[n−

9] (modulo 2).

11. The computer program product of claim 8 in which the pseudo random generated 11-bit word is seeded by a port number of the diode discovery device.

12. A diode discovery system comprising:

a diode discovery process controller to;

transmit a pulse signal from the controller on a first line;

receive the pulse signal in the controller on a second line;

measure a time to charge a capacitor in a diode detection circuit in response to applying power to determine the power level;

apply power in response to comparing the transmitted pulse signal to the received pulse signal and to the measured time;

a voltage source connected to the controller; and

a power converter linked to the diode detection circuit.

13. The system of claim 12 in which the pulse signal includes pseudo random generated 11-bit word.

14. The system of claim 13 in which the pseudo random generated 11-bit word is generated by a recursive linear function.
