Abstract

An apparatus for mitigating unwanted life forms, the apparatus comprising: a sensor system configured to detect an unwanted life form; an adjustable first electrode; an earthed second electrode; a voltage generator connected to the first and second electrodes; a conductivity generator for increasing conductivity between the first electrode and the unwanted life form; and a controller in communication with the sensor system, the voltage generator and the conductivity generator, the controller, using a signal from sensor system, adjusting the first electrode to a position adjacent to yet separate from the unwanted life form and the second electrode, engaging the conductivity generator and initiating a transfer of charge from the first electrode to the life form using the increased conductivity of the air between the first electrode and the life form.

Claims (52)

1 . A vehicle for mitigating unwanted life forms, the vehicle comprising:

a sensor system configured to detect an unwanted life form;

a first arrangement including a first electrode and a first nozzle configured to produce a first water jet, wherein a position of the first arrangement relative to the vehicle is adjustable;

a second arrangement including a second electrode and a second nozzle configured to produce a second water jet;

a voltage generator connected to the first and second electrodes;

a controller in communication with the sensor system, the voltage generator, the first electrode, the first arrangement, and the second arrangement, the controller to at least:

using a signal from the sensor system, adjust the first arrangement to a position adjacent to, yet separate from, the unwanted life form and the second electrode;

engage the first nozzle to produce the first water jet, wherein the first water jet increases a conductivity between the first electrode and the unwanted life form, wherein the first water jet includes an additive that increases a stability of the first water jet;

engage the second nozzle to produce the second water jet, wherein the second electrode is grounded through the second water jet; and

after producing the first water jet and the second water jet, control the voltage generator to initiate a transfer of charge from the voltage generator through the first electrode, through the unwanted life form, and to the second electrode.

2 . The vehicle of claim 1 , wherein the controller is configured to control a quantity of voltage transmitted to the unwanted life form using a sensed property of the unwanted life form generated at least in part by the sensor system.

3 . The vehicle of claim 2 , wherein the sensed property is at least one of a size of the unwanted life form, a degree of dryness of the unwanted life form, and a temperature of the unwanted life form.

4 . The vehicle of claim 1 , wherein the controller is configured to modify a sensed property of the unwanted life form using the first water jet.

5 . The vehicle of claim 4 , wherein the sensed property is a temperature of the unwanted life form.

6 .

7 . The vehicle of claim 1 , wherein the controller applies high voltage to the first electrode once the controller has applied the first water jet to increase the conductivity between the first electrode and the unwanted life form.

8 . The vehicle of claim 1 , wherein the second electrode is grounded by a contact that penetrates a ground.

16 . The method of claim 10 , further including applying high voltage to the first electrode once the controller has applied the first water jet to increase the conductivity between the first electrode and the unwanted life form.

17 . The method of claim 10 , wherein:

boring a hole into an insulating layer of material by applying the high-pressure jet; and

forming an electrical connection between the high-pressure jet and the unwanted life form, the unwanted life form located under the insulating layer.

18 . A system comprising:

a vehicle;

an apparatus for mitigating unwanted life forms mounted to the vehicle, the apparatus including:

a sensor system configured to detect an unwanted life form;

a first arrangement including a first electrode and a first nozzle configured to produce a first water jet, wherein a position of the first arrangement relative to the vehicle is adjustable;

a second arrangement including a second electrode and a second nozzle configured to produce a second water jet;

a voltage generator connected to the first and second electrodes;

a controller in communication with the sensor system, the voltage generator, the first electrode, the first arrangement, and the second arrangement, the controller to at least:

using a signal from the sensor system, adjust the first arrangement to a position adjacent to, yet separate from, the unwanted life form and the second electrode;
