Multi-factorial electronic shark repellant

In abstract this invention is a pressure and water sealed unit small enough to be worn by a swimmer. It contains a rechargeable battery, control interface logic, digital signal generation, and amplification circuitry. It uses a ground balanced electrode system to produce electric fields in the very low impedance environment of water. These fields are organized into patterns called words. These words are presented in a hierarchal pseudo random manner to prevent target organisms from learning and adapting to them. The presentation of these words is controlled by upgradable programing stored within memory. The words evoke central nervous system (CNS) responses which result in sharks leaving the area of operation. These words represent stimuli of predators, navigation signals, noxious events, CNS interference patterns, and other sequences found to repel sharks from the protected area. Reprogrammability allows upgrades to newer sequences. The amplifier uses switching stages to multiply the battery voltage up to about one thousand times. An inversion unit provides for positive and negative signals. The switching circuit is logic level and pulse width modulation controlled. The switching typology permits micro miniaturization and efficient power consumption prolonging battery life. The unit has no user adjustable parameters except for go no-go control and shark alarm. Unit and battery status is indicated by flashing light signals. Electrode typology generates a spherical electric wave propagation pattern in water. A recharging cradle projects magnetic energy into the unit providing for automatic battery recharging and conditioning without electrical connections exposed to an aqueous environment.

The invention discloses a shark driving wrist guard for underwater emergency risk avoiding, and relates to the technical field of underwater risk avoiding. The shark driving wrist guard for underwater emergency danger avoiding comprises a bracelet, a fixing box is fixedly connected to the upper surface of the bracelet, a blocking piece is fixedly connected to the front side of the fixing box, a gas generating mechanism is arranged on the side portion of the fixing box, and a first spring is fixedly connected to the rear side of the inner wall of the fixing box; the front end of the first spring is fixedly connected with a blade, the upper surface of the blade is fixedly connected with a top block, and the outer wall of the blade is slidably connected with the inner wall of the fixed box. According to the shark driving wrist guard for underwater emergency danger avoiding, when the blade extends out, air rushes into the sliding cavity through the air pipe, so that the ejector rod ascends to lift the first limiting block, the first limiting block does not limit the second spring any more, the wing plate is bounced off by the second spring, the wing plate is opened to enable swimming and turning to be more convenient, and underwater fighting with a shark is more facilitated.
