A geofenced autonomous aquatic drone for repelling sharks from a shoreline. The drone employs a buoyant housing resembling a portion of a predator such as an orca whale. A battery positioned within the drone is recharged through a floating inductive charging station. A transmitter unit coupled to at least one under water transducer introduces certain sounds, such as reproduction of orca whale or dolphin calling sounds. A propulsion system controlled a microprocessor receives location information via DGPS for providing a geofence around an area to be patrolled. The drone travels within the geofence area, monitored by the DGPS receiver, while said transducer produces certain sounds and or a solution of shark repellant is dispensed.

A sonar device is constructed and arranged to detect sharks. The drone travels within the geofence area, monitored by the DGPS receiver and a solution of shark repellant is dispensed.

A garment to repel underwater aquatic creatures. A first component for generating a control signal and a second component for receiving the control signal and transmitting an electromagnetic signal responsive thereto, an electromagnetic field created by the electromagnetic signal radiating from the second component into an aquatic area surrounding the garment. A water sensor disposed on the garment for activating the first and second components to transmit the electromagnet signal when the water sensor senses presence of water.

Removable device for repelling marine mammals, such as orcas, intended for use on a ship's rudder. The invention relates to a removable device (1) for repelling marine mammals, such as orcas, intended for use on a ship's rudder, comprising: - at least one flexible support (2), preferably elastic, the length of which is adapted to surround an outer surface of a portion of a ship's rudder, the flexible support incorporating a plurality of prongs (3) distributed along its length, - at least one removable fastening element (4) for the flexible support in a configuration where it surrounds the outer surface of a portion of a ship's rudder.

The invention relates to a removable device (1) for repelling marine mammals, such as orcas, intended to be fitted to a ship's rudder, comprising: - at least one flexible support (2), preferably elastic, the length of which is adapted to surround an outer surface of a part of a ship's rudder, the flexible support incorporating a plurality of spikes (3) distributed along its length, - at least one removable fixing element (4) for the flexible support in a configuration where it surrounds the outer surface of a part of a ship's rudder.

The present disclosure relates to a surf craft comprising one or more illuminated regions on an underside of the surf craft, the underside defining a surface that faces a body of water in use. The disclosure also relates to a method of reducing interactions with sharks, the method comprising arranging one or more illuminated portions on an underside of a surf craft, the underside defining a surface that faces a body of water in use, and a system for reducing interaction of sharks with a surf craft, the system comprising arranging one or more lights on at least a portion of downward facing surfaces of the surf craft, the one or lights being arranged such that the surf craft is counter-illuminated.

A wrist-worn electromagnetic pulse generating wearable device for repelling great white sharks, tiger sharks, and bull sharks. i.e., the lethal shark breeds. The device includes an artificial intelligence / machine learning component (AI / ML) trained on a dataset including characteristics of the lethal shark breeds. A hydroactive sensor activates the device upon immersion in marine or fresh water. A signal generating component, responsive to AI / ML component, generates an ELF signal that radiates out to a 4 m area surrounding the user to repel shark attacks. Wave pulse characteristics, such as frequency, waveshape, and magnitude are determined by the AI / ML algorithm based on the detected shark breed. Antenna design based on fractal geometry (e.g., the T-square fractal, or the Sierpinski Triangle) generates an ideal isotropic radiation pattern. The wrist-mounted form factor of the inventive device offers improved performance over prior art devices.
