- Shark_proof_cage abstract "A shark proof cage is an extremely strong, metal cage used by a scuba diver to safely examine dangerous types of sharks up close. This can include various species of shark, but the most commonly observed within the confines of a cage are the great white shark and the bull shark, which are both known to be aggressive at times. Shark proof cages are built to withstand being rammed at high velocities, and be able to protect the user from massive force from attacks. Cages can provide a visual and tactile deterrent to sharks. Cage-diving allows people to closely monitor sharks, and sometimes interact with them.The shark proof cage is also used in the controversial exercise of shark baiting, where tourists are lowered in a cage while the tour guides bait the waters for sharks.On September 4, 1979, US patent number 4166462 was issued for a self-propelled shark proof cage; being designed to allow abalone divers to collect abalone without becoming vulnerable to attack. Thanks to the propulsion system, abalone divers would exert themselves less and, therefore, be able to collect their prey for longer periods of time. The patent abstract details a self-propelled cage with at least one access opening and a propeller mounting frame that carries both an air motor and a propeller. Buoyant objects are attached to the frame so that the cage may be made approximately the same density as saltwater. This patent expired on September 4, 1996.".
