Abstract

An apparatus includes a capsule configured to be launched or carried towards an unmanned aerial vehicle (UAV). The apparatus also includes a directed energy device within or carried by the capsule. The directed energy device includes a first inductor configured to generate an inductive magnetic field that is able to inductively couple into one or more electronics of the UAV in order to disable or destabilize the UAV. The capsule can be configured to be launched towards the UAV and can include a loiter mechanism (such as a rotor, umbrella, or parachute) configured to maintain a position of the capsule or to slow a descent of the capsule after launch. The capsule can also be configured to be carried towards the UAV by a different UAV, and the apparatus can further include a tether coupling the capsule to the different UAV.

First claim

What is claimed is:

1. An apparatus comprising:
a capsule configured to be launched or carried towards an unmanned aerial vehicle (UAV); and
a directed energy device within or carried by the capsule, the directed energy device comprising:
a first inductor configured to generate a magnetic field that is able to disable or destabilize one or more electronics of the UAV;
a power supply configured to provide a supply voltage;
a power converter configured to receive the supply voltage and generate an output voltage different from the supply voltage; and
a power amplifier driver circuit configured to generate a drive signal for a transistor switch, wherein operation of the transistor switch causes generation of the magnetic field based on the output voltage.

2. The apparatus of claim 1 , further comprising:
a loiter mechanism configured to maintain a position of the capsule or to slow a descent of the capsule after launch and prior to engagement with the UAV in order to hold the apparatus within a flight path of the UAV.

3. The apparatus of claim 2 , wherein the loiter mechanism comprises at least one of: a rotor, an umbrella, and a parachute.

4. The apparatus of claim 1 , wherein the apparatus is reusable.

5. The apparatus of claim 1 , wherein the first inductor and a capacitor form a resonant tank circuit.

6. The apparatus of claim 5 , wherein the directed energy device further comprises a second inductor through which a varying electrical current is able to flow and be mutually inducted into the resonant tank circuit.

7. The apparatus of claim 1 , wherein:
the capsule is configured to be carried towards the UAV by a second UAV; and
the apparatus further comprises a tether configured to couple the capsule to the second UAV.

8. The apparatus of claim 7 , wherein the directed energy device is configured to receive electrical power through the tether from the second UAV.

9. A system comprising:
a plurality of apparatuses each comprising:
a capsule configured to be launched towards an unmanned aerial vehicle (UAV); and
a directed energy device within or carried by the capsule, the directed energy device comprising:
a first inductor configured to generate a magnetic field that is able to disable or destabilize one or more electronics of the UAV;
a power supply configured to provide a supply voltage;
a power converter configured to receive the supply voltage and generate an output voltage different from the supply voltage; and
a power amplifier driver circuit configured to generate a drive signal for a transistor switch, wherein operation of the transistor switch causes generation of the magnetic field based on the output voltage; and

a launcher configured to launch the capsules, the launcher comprising a tube.

10. The system of claim 9 , wherein each apparatus further comprises:
a loiter mechanism configured to maintain a position of the capsule or to slow a descent of the capsule after launch and prior to engagement with the UAV in order to hold the apparatus within a flight path of the UAV.

11. The system of claim 10 , wherein the loiter mechanism comprises at least one of: a rotor, an umbrella, and a parachute.

12. The system of claim 9 , wherein at least one of the apparatuses is reusable.

13. The system of claim 9 , wherein, in each apparatus, the first inductor and a capacitor form a resonant tank circuit.

14. The system of claim 13 , wherein the directed energy device of each apparatus further comprises a second inductor through which a varying electrical current is able to flow and be mutually inducted into the resonant tank circuit.

15. A system comprising:
a first unmanned aerial vehicle (UAV); and
one or more apparatuses each comprising:
a capsule configured to be carried by the first UAV towards a second UAV; and
a directed energy device within or carried by the capsule, the directed energy device comprising:
a first inductor configured to generate a magnetic field that is able to disable or destabilize one or more electronics of the second UAV;
a power supply configured to provide a supply voltage;
a power converter configured to receive the supply voltage and generate an output voltage different from the supply voltage; and
a power amplifier driver circuit configured to generate a drive signal for a transistor switch, wherein operation of the transistor switch causes generation of the magnetic field based on the output voltage;

wherein the first UAV is maneuverable to engage the second UAV.

16. The system of claim 15 , further comprising:
a tether coupling the one or more apparatuses to the first UAV.

17. The system of claim 16 , wherein the directed energy device of each apparatus is configured to receive electrical power through the tether from the first UAV.

18. The system of claim 15 , wherein, in each apparatus, the first inductor and a capacitor form a resonant tank circuit.

19. The system of claim 18 , wherein the directed energy device of each apparatus further comprises a second inductor through which a varying electrical current is able to flow and be mutually inducted into the resonant tank circuit.

20. A method comprising:
moving a reusable directed energy device towards an unmanned aerial vehicle (UAV); and
generating a magnetic field using the directed energy device, the magnetic field able to disable or destabilize one or more electronics of the UAV;
wherein the directed energy device comprises:
