Segmented projectile launches an instant adhesive and weighted water parachute to create constant torque, arresting small vessels without structural damage.
Vertical locking bolts absorb crash forces through controlled deformation, reducing lifting device complexity and manufacturing costs.
Inflatable buoyancy tanks with pressure-balancing means adjust a flat-bottom boat's draft and width to navigate shallow waters and narrow locks.
Segmented laser transmitters and detectors map object characteristics across elevation angles, resolving measurement precision versus device complexity.
