Abstract

Among the embodiments of the present invention are pest control devices (1010, 1110, 1210) each operable to detect the presence of pests. The pest control device (1010, 1110, 1210) has a bait (1032) that is consumed or displaced by one or more species of pest, a pest sensing circuit (1052, 1152, 1252), and a monitoring circuit (1069, 1169, 1269). The pest sensing circuit (1052, 1152, 1252) can be altered by pest activity. The monitoring circuit (1069, 1169, 1269) detects this alteration and reports it automatically or in response to an external stimulus or interrogation to indicate pest presence.

Claims

1. A method comprising:

operating a plurality of pest control devices each including a respective bait for one or more species of pest, a respective pest sensing circuit, a respective visual indicator arrangement, and a respective controller circuit; and

providing light from the respective visual indicator arrangement of one of the pest control devices in accordance with a periodic pattern of variation to represent one state of the respective pest sensing circuit of the one of the pest control devices;

wherein said one of the pest control devices includes a respective housing, said respective housing including said respective bait for one or more species of pest, said respective pest sensing circuit, said respective visual indicator arrangement, and said respective controller circuit.

2. The method of claim 1, which includes:

detecting a change in status of the respective pest sensing circuit with the respective controller circuit for the one of the pest control devices;

adjusting one or more output signals from the respective controller circuit of the one of the pest control devices in response to the change in status; and

changing a visual indication provided with the respective visual indicator arrangement in response to the one or more output signals.

3. The method of claim 2, wherein the one state corresponds to the status of the respective pest sensing circuit before said detecting, the light emitted during said providing is of a first color, and said changing includes emitting light of a second color different than the first color to represent another state of the respective pest sensing circuit of the one of the pest control devices.

4. The method of claim 3, wherein the periodic pattern of variation includes repetitively blinking the light of the first color with the visual indicator arrangement and said emitting includes repetitively blinking the light of the second color.

5. The method of claim 1, wherein said providing includes alternating a light-emitting device of the visual indicator arrangement between an on state and an off state to provide a blinking form of the periodic pattern of variation, and the one state corresponds to detecting pest activity with the respective pest sensing circuit of the one of the pest control devices.

6. The method of claim 1, wherein the periodic pattern of variation includes changing the intensity of the light between two nonzero levels.

7. The method of claim 1, wherein said installing includes activating the respective controller circuit of each of the pest sensing devices by coupling the respective controller to the respective pest sensing circuit with a corresponding connector.

8. The method of claim 1, wherein the pest sensing circuit includes an electrically conductive loop on a substrate configured to be altered by consumption or displacement by the one or more species of pest.

9. The method of claim 1, wherein said detecting includes determining a transition from a first degree of alternation of the pest sensing circuit to a second degree of alternation of the pest sensing circuit caused by progressive consumption or displacement by the one or more species of pest.

10. The method of claim 1, which includes periodically blinking light emitted from another of the pest control devices to represent a predefined state of the respective pest sensing circuit.

11. The method of claim 1, wherein the respective bait of the one of the pest control devices includes a pesticide.

12. The method of claim 1, wherein the respective bait of the one of the pest control devices is of a monitoring type selected for one or more varieties of termites.

13. The method of claim 1, wherein said respective pest sensing circuit includes an electrically conductive network.

14. The method of claim 1, which includes installing said respective pest sensing circuit underground.

15. A method comprising:

installing a plurality of pest control devices each including a respective bait for one or more species of pest, a respective pest sensing circuit, a respective visual indicator arrangement, and a respective controller circuit;

emitting light of a first color from, the respective indicator arrangement of one of the pest control devices to represent a first state of the respective pest sensing circuit;

detecting a change in status of the respective pest sensing circuit with the respective controller circuit for the one of the pest control devices;

adjusting one or more output signals from the respective controller circuit of the one of the pest control devices in response to the change in status; and

emitting light of a second color different than the first color from the respective visual indicator arrangement of the one of the pest control devices to represent a second state of the respective pest sensing circuit;

wherein said one of the pest control devices includes a respective housing, said respective housing including said respective bait for one or more species of pest, said respective pest sensing circuit, said respective visual indicator arrangement, and said respective controller circuit.

16. The method of claim 15, wherein the first color is green and the second color is red.

17. The method of claim 15, which includes blinking at least one of the light of the first color and the light of the second color.

18. The method of claim 15, wherein said installing includes activating the respective controller circuit of each of the pest sensing devices by coupling the respective controller to the respective pest sensing circuit with a corresponding connector.

19. The method of claim 15, wherein the pest sensing circuit includes an electrically conductive loop on a substrate configured to be altered by consumption or displacement by the one or more species of pest.

20. The method of claim 15, wherein said detecting includes determining a transition from a first degree of alternation of the pest sensing circuit to a second degree of alternation of the pest sensing circuit caused by progressive consumption or displacement by the one or more species of pest.

21. The method of claim 15, which includes periodically blinking light emitted from another of the pest control devices to represent a predefined state of the respective pest sensing circuit.

22. The method of claim 15, wherein the respective bait of the one of the pest control devices includes a pesticide.

23. The method of claim 15, wherein the respective bait of the one of the pest control devices is of a monitoring type selected for one or more varieties of termites.

24. The method of claim 15, wherein said respective pest sensing circuit includes an electrically conductive network.

25. The method of claim 15, wherein said installing includes installing at a portion of one of the respective pest sensing circuit underground.
