## Abstract

A method for controlling an unmanned aerial vehicle (UAV) to track a monitored person is provided. The method includes directing the UAV toward a target location the target location being based on past or present location information provided by a personal monitoring device attached to a monitored person, the location information representing the location of the personal monitoring device; assuming with the UAV a surveillance position relative to the target location; and determining that the monitored device is proximate to the target location by receiving signals from the personal monitoring device and/or observing the monitored person through a camera on the UAV.

## Claims

### Claim 1

A method for controlling an unmanned aerial vehicle (UAV) to track a monitored person, comprising:
directing the UAV toward a target location the target location being based on past or present location information provided by a personal monitoring device attached to a monitored person, the location information representing the location of the personal monitoring device;
assuming with the UAV a surveillance position relative to the target location;
determining that the monitored device is proximate to the target location; comprising:
receiving short range signals from the personal monitoring device; and/or
observing the monitored person through a camera on the UAV.

### Claim 2 (depends on 1)

The method of claim 1, wherein:
the location information is GPS coordinates sent by the personal monitoring device; and
the target location is the GPS coordinates sent by the personal monitoring device.

### Claim 3 (depends on 1)

The method of claim 1, further comprising adjusting the surveillance position and/or camera orientation.

### Claim 4 (depends on 1)

The method of claim 1, wherein the determining is further based on the short range signals.

### Claim 5 (depends on 1)

The method of claim 1, wherein the determining is further based on whether any obstruction blocks the camera from observing the monitored person.

### Claim 6 (depends on 1)

The method of claim 1, further comprising:
in response to an indication that the location information from the personal monitoring device is no longer available or accurate:
discontinuing tracking based on location information from the personal monitoring device; and
tracking, with the UAV, a mobile device associated with the monitored person.

### Claim 7 (depends on 1)

The method of claim 1, wherein the assuming comprises applying predetermined rules on where to position the UAV relative to a specific location.

### Claim 8 (depends on 1)

The method of claim 1, wherein the location information is GPS coordinates determined by a monitoring authority.

### Claim 9 (depends on 1)

The method of claim 1, further comprising:
predicting, based on prior location information provided by the personal monitoring device, a potential location of the monitored person; and
setting the potential location as the target location.

### Claim 10 (depends on 1)

The method of claim 1, further comprising:
determining one of: if the monitored person is at the target location, if the monitored person is not at the target location and if the monitored person had lost connection then reconnected with the central monitoring unit and
issuing an alert in response to a result of the determining.

### Claim 11

A method for controlling an unmanned aerial vehicle (UAV) with a camera having an adjustable orientation, comprising:
directing the UAV toward a target location, the target location being based on past or present location information provided by a personal monitoring device attached to a monitored person, the location information representing the location of the personal monitoring device;
assuming with the UAV a surveillance position relative to the target location;
aligning the camera of the UAV to observe the monitored person;
determining if an adjustment to the surveillance position and/or camera orientation is needed based on at least a change in the location of the personal monitoring device; and
adjusting, in response to the determining, the surveillance position and/or camera orientation.

### Claim 12 (depends on 11)

The method of claim 11, wherein:
the location information is GPS coordinates sent by the personal monitoring device;
the target location is the GPS coordinates sent by the central monitoring system; and
the change in the location of the personal monitoring device determined by updated GPS coordinates sent by the personal monitoring device.

### Claim 13 (depends on 11)

The method of claim 11, wherein the adjusting is in response to an override command from a monitoring authority.

### Claim 14 (depends on 11)

The method of claim 11, further comprising:
receiving short range signals from the personal monitoring device; and
the determining is further based on the short range signals.

### Claim 15 (depends on 11)

The method of claim 11, wherein the determining is further based on whether any obstruction blocks the camera from observing the monitored person.

### Claim 16 (depends on 11)

The method of claim 11, further comprising:
in response to an indication that the location information from the personal monitoring device is no longer available or accurate:
discontinuing tracking based on location information from the personal monitoring device; and
tracking, with the UAV, a mobile device associated with the monitored person.

### Claim 17 (depends on 11)

The method of claim 11, wherein the assuming comprises applying predetermined rules on where to position the UAV relative to a specific location.

### Claim 18 (depends on 11)

The method of claim 11, wherein the location information is GPS coordinates determined by a monitoring authority.

### Claim 19 (depends on 11)

The method of claim 11, further comprising:
predicting, based on prior location information provided by the personal monitoring device, a potential location of the monitored person; and
setting the potential location as the target location.

### Claim 20 (depends on 11)

The method of claim 11, further comprising:
determining one of: if the monitored person is at the target location, if the monitored person is not at the target location and if the monitored person had lost connection then reconnected with the central monitoring unit; and
issuing an alert in response to a result of the determining.
