Aquatic animal detangling device of benthic gear and mooring lines

1. A detangling device for severing a mooring line, the device comprising:

a line cutting assembly comprising: an ignition device, a propellant chamber, a moveable shuttle-knife assembly and a knife;

a pressure sensor; and

a second pressure sensor;

a control system configured to monitor the pressure sensor and actuate the line cutting assembly when the monitored pressure sensor indicates a threshold depth is exceeded, wherein the control system is further configured to monitor the second pressure sensor, and

wherein the control system includes one or more processors configured to perform:

receiving operating parameters;

monitoring input from the pressure sensor and the second pressure sensor; and

actuating the line cutting assembly to sever the mooring line based upon the monitored input from the pressure sensor and the second pressure sensor.

2. The detangling device of claim 1 , wherein the line cutting assembly further comprises:

a sealed cylindrical interior, housing the ignition device, the propellant chamber, the moveable shuttle-knife assembly, and the knife, and wherein the sealed cylindrical interior includes a circular-shaped wall having a thinned portion aligned with the knife.

3. The detangling device of claim 2 , wherein the thinned portion has a lesser wall thickness than most of the circular-shaped wall.

4. The detangling device of claim 1 , further comprising:

a water sealed housing for containing the line cutting assembly, the pressure sensor, and the control system; and

wherein the line cutting assembly is sealably connected to the water sealed housing via one or more o-rings.

5. The detangling device of claim 4 , wherein the line cutting assembly is perpendicular to an opening configured to receive the mooring line.

6. A detangling device for severing a mooring line, the device comprising:

a line cutting assembly;

a first and a second pressure sensors;

a water sealed housing for containing the line cutting assembly, and the pressure sensor, wherein the line cutting assembly is sealably connected to the water sealed housing via one or more o-rings at a perpendicular angle to an opening configured to receive the mooring line, wherein the perpendicular angle is relative between the line cutting assembly and the opening; and

a control system, contained within the water sealed housing, configured to monitor the first and second pressure sensors and actuate the line cutting assembly based upon monitored input therefrom, wherein the control system includes one or more processors configured to perform:

receiving operating parameters;

monitoring input from the first and second pressure sensors; and

actuating the line cutting assembly to sever the mooring line based upon the monitored input from the first and second pressure sensors and an accelerometer.

7. The detangling device of claim 6 , wherein the control system is communicatively connected to a computing device; and wherein the one or more processors are further configured to perform:

receiving instructions from the computing device to sever the mooring line; and

actuating the line cutting assembly to sever the mooring line based upon the received instructions.

8. The detangling device of claim 7 , wherein the line cutting assembly further comprises:

a sealed cylindrical interior, housing an ignition device, a propellant chamber, a moveable shuttle-knife assembly, and a knife, and wherein the sealed cylindrical interior includes a circular-shaped wall having a thinned portion aligned with the knife, wherein the thinned portion has a lesser wall thickness than most of the circular-shaped wall.

9. The detangling device of claim 8 , wherein the one or more processors are further configured to perform:

receiving instructions from the computing device to transmit information from the first and second pressure sensors; and

transmitting information from the first and second pressure sensors to the computing device.
