Abstract

Dispenser devices suitable for use on unmanned aerial vehicles are described having utility for dispensing solid larvicides to difficult to reach insect habitats.

First claim

What is claimed is:

1. A linear dispenser device for an unmanned aerial system (UAS) for releasing one or more solid briquettes or tablets at a location of interest, comprising:
a body housing a control board and having supporting arms with means for mounting said body onto legs of the unmanned aerial system (UAS), said body having a lid, a charge port, indicator lights, an on/off switch, and a wire hole;
a hopper connected to said body for holding the briquettes or tablets above a mouth of the body;
a servo attached to a servo arm with a shuttle located in the mouth;
a separate opaque light cover connectable to the UAS for replacing a clear lens on the UAS; and
a light sensor configured to be positioned by said light cover directly below a light on the UAS;
wherein the light sensor is configured to detect when the light of the UAS is on or off and to send signals to the control board; and
wherein the control board is configured to signal the servo to swing the shuttle back from the mouth with the servo arm for allowing one of the briquettes or tablets to drop from the hopper into the mouth when the light sensor detects the light of the UAS being turned on or off, and to move the shuttle forward to push the briquette or tablet out of the mouth when the light sensor detects the light of the UAS being switched back off or on, thereby releasing the briquette or tablet at the location of interest.

2. The linear dispenser device according to claim 1 , further comprising one or more of the briquettes or tablets contained within said hopper, and wherein said briquettes or tablets comprise a larvicide which impairs mosquito breeding ability or is lethal to mosquitoes.

3. A method for controlling insect or mosquito populations at locations of interest, comprising:
filling the hopper of the linear dispenser device of claim 1 with one or more briquettes or tablets comprising a larvicide which impairs mosquito breeding ability;
mounting said linear dispenser device to the UAS via said means for mounting the body, wherein said means comprises clips;
flying said UAS to said location of interest and turning the light of the UAS on or off;
wherein when the light is turned on or off, said control board signals the servo to swing the shuttle back allowing one of the briquettes or tablets to drop into the mouth; and
wherein switching the light back off or on causes the shuttle to move forward, pushing the briquette or tablet out of the mouth, thereby releasing said briquette or tablet at said location of interest.

4. The linear dispenser device according to claim 1 , further comprising a power board and a battery housed within the body, wherein the light sensor is wired to the control board which is wired to the power board and the servo, the power board also being wired to the battery.

5. A linear dispenser device for releasing one or more solid briquettes or tablets at a location of interest from an unmanned aerial system (UAS) having a light, comprising:
a body for housing electronics and having support arms with clips for mounting said body on the UAS, the body defining a mouth through which a briquette or tablet may be released, said electronics including a control board and a servo;
a hopper connected to said body for containing a supply of briquettes or tablets adjacent the mouth;
a servo arm extending from the servo and configured to locate a shuttle in positions within and outside of the mouth; and
a light sensor configured to be mounted adjacent the light of the UAS, to detect when the light of the UAS is toggled from on to off and from off to on, and to transmit signals to the control board;
wherein the control board is configured to cause the servo to move the shuttle with the servo arm out of the mouth to permit a briquette or tablet to drop from the hopper into the mouth, when the light sensor detects the light of the UAS having been toggled, and to move the shuttle to push the briquette or tablet out of the mouth, when the light sensor detects the light of the UAS being toggled again to thereby release the briquette or tablet at a location of interest.

6. The linear dispenser device according to claim 5 , further comprising one or more briquettes or tablets contained within said hopper, and wherein said briquettes or tablets comprise a larvicide which impairs mosquito breeding ability or is lethal to mosquitoes.

7. The linear dispenser device according to claim 5 , wherein the electronics further comprise a power board and a battery, wherein the light sensor is wired to the control board, wherein the control board is wired to the power board and the servo, and wherein the power board is wired to the battery.

8. A method for controlling insect or mosquito populations, comprising:
mounting said linear dispenser device according to claim 5 to legs of an UAS via said clips, said hopper of said linear dispenser device containing a supply of briquettes or tablets comprising a larvicide which impairs mosquito breeding ability;
flying said UAS to a location of interest and toggling a light of the UAS to cause a briquette or tablet to be released from the linear dispensing device at said location of interest.

9. An unmanned aerial system (UAS) with linear dispenser device for releasing one or more solid briquettes or tablets at a location of interest, said UAS having legs and at least one remotely actuatable light, and said linear dispenser device comprising:
a body for housing electronics and having support arms mounted to the legs of the UAS, the body defining a mouth through which a briquette or tablet may be released, said electronics including a control board and a servo;
a hopper connected to said body for containing a supply of briquettes or tablets adjacent the mouth;
a servo arm extending from the servo and configured to locate a shuttle in positions within and outside of the mouth; and
a light sensor mounted adjacent the light of the UAS to detect when the light of the UAS is toggled from on to off or from off to on and to transmit signals to the control board;
wherein the control board is configured to cause the servo to move the shuttle with the servo arm out of the mouth to permit a briquette or tablet to drop from the hopper into the mouth, when the light sensor detects the light of the UAS having been toggled, and to move the shuttle to push the briquette or tablet out of the mouth, when the light sensor detects the light of the UAS being toggled again to thereby release the briquette or tablet at the location of interest.

10. The unmanned aerial system (UAS) with linear dispenser device according to claim 9 , wherein the UAS is a quadcopter.

11. The unmanned aerial system (UAS) with linear dispenser device according to claim 9 , further comprising one or more briquettes or tablets contained within said hopper, and wherein said briquettes or tablets comprise a larvicide which impairs mosquito breeding ability or is lethal to mosquitoes.

12. The unmanned aerial system (UAS) with linear dispenser device according to claim 9 , wherein the electronics further comprise a power board and a battery, wherein the light sensor is wired to the control board, wherein the control board is wired to the power board and the servo, and wherein the power board is wired to the battery.

13. A method for controlling insect or mosquito populations, comprising:
remotely controlling flight of the UAS with linear dispenser device according to claim 9 to a location of interest; and
remotely causing the light of the UAS to be toggled to cause a briquette or tablet to be released from the linear dispensing device at said location of interest.
