Abstract

A circuit for actuating a switch includes a conductive liquid switch comprising a conductive liquid droplet and a control processor configured to receive a switching signal and configured to provide at least one actuation pulse to the conductive liquid droplet to initiate movement of the conductive liquid droplet based on a duration of a time period between the switching signal and a preceding switching signal.

Claims (27)

1. A circuit for actuating a switch, comprising:

a conductive liquid switch comprising a conductive liquid droplet; and

a control processor configured to receive a switching signal and configured to provide at least one actuation pulse to the conductive liquid droplet to initiate movement of the conductive liquid droplet based on a duration of a time period between the switching signal and a preceding switching signal.

2. The circuit of claim 1 , further comprising a timer for determining the time period between at least two switching signals.

3. The circuit of claim 2 , further comprising a predetermined threshold value against which the time period is measured.

4. The circuit of claim 3 , further comprising at least one transistor for providing a plurality of actuation pulses to the switch when the time period between switching signals at least equals the predetermined threshold.

5. The circuit of claim 3 , further comprising at least one transistor for providing a single actuation pulse to the switch when the time period between switching signals is less than the predetermined threshold.

6. The circuit of claim 3 , in which the predetermined threshold is thirty minutes.

7. The circuit of claim 3 , in which the predetermined threshold is determined based on the material of the conductive liquid droplet.

8. A method for actuating a switch, comprising:

providing a conductive liquid switch comprising a conductive liquid droplet;

receiving a switching signal in a control processor associated with the switch; and

providing an actuation signal comprising at least one actuation pulse to initiate movement of the conductive liquid droplet based on a duration of a time period between the switching signal and a preceding switching signal.

9. The method of claim 8 , further comprising determining the time period between a plurality of switching signals.

10. The method of claim 9 , further comprising measuring the time period against a predetermined threshold.

11. The method of claim 10 , further comprising determining if the time period between switching signals exceeds the predetermined threshold.

12. The method of claim 11 , further comprising providing a plurality of actuation pulses to the switch when the time period between switching signals at least equals the predetermined threshold.

13. The method of claim 11 , further comprising providing a single actuation pulse to the switch when the time period between switching signals is less than the predetermined threshold.

14. The method of claim 11 , in which the predetermined threshold is thirty minutes.

15. A method for actuating a switch, comprising:

providing a conductive liquid switch comprising a conductive liquid droplet;

receiving a switching signal in a control processor associated with the switch; and

providing an actuation signal comprising a plurality of actuation pulses to initiate movement of the conductive liquid droplet based on a duration of a time period between the switching signal and a preceding switching signal.

16. The method of claim 15 , further comprising determining the time period between a plurality of switching signals.

17. The method of claim 16 , further comprising measuring the time period against a predetermined threshold.

18. The method of claim 16 , further comprising determining if the time period between switching signals exceeds the predetermined threshold.

19. The method of claim 18 , further comprising providing a plurality of actuation pulses to the switch when the time period between switching signals at least equals the predetermined threshold.
