The present invention includes a transparent surfboard or wave-riding vehicle. The present invention also includes a transparent surfboard with an optional embedded locater for large aquatic animals and an alarm for the wave rider, specifically prepared to identify animals such as sharks, and an optional shark-resistant signal generator that transmits an interference signal to interrupt the electrical impulses used by aquatic animals for electrical sense. More specifically these aquatic animals are greater than three feet in length (such as a shark) and within approximately a one-hundred foot radius of the surfboard with regard to the sensory perception of a shark, thus diverting or distracting it from any one in the water in the vicinity of the device. The transparency of the surfboard or wave-riding vehicle is achieved by manufacturing the surfboard blank with transparent super microcellular polymer foams and coating the blank with a clear, transparent polymer.

A surfboard shark repellent system for repelling sharks away from an individual while surfing. The surfboard shark repellent system includes an attachable magnet and a transmitter unit that emits sound waves at a frequency undesirable to sharks. The transmitter unit is contained in a watertight enclosure affixed to the upper surface towards the rear end of a surfboard usually submerged in the water while the user waits for a wave. The magnet attaches to the transmitter unit functioning as an on/off switch for the transmitter unit and is also connected to the user by a tether and band.

A method for extracting shark calcium chondroitin sulfate from a shark cartilage comprises the processes in sequence such as curing, alkalization, enzymatic hydrolysis, deproteinization, crystallization, resin pretreatment, resin exchange, ultrafiltration dehydration, calcification of filtrate and crystallization dehydration dying. Because secondary crystallization is adopted, the covalent binding of protein and shark chondroitin sulfate is broken by hydrogen peroxide to enable the chondroitin sulfate in the protein to be dissociated, impurities such as the protein and the like can be effectively removed to improve the purity and the content of shark sodium chondroitin sulfate; cation resin is adopted to complete the sodium removal process by column chromatography, the exchanged shark chondroitin sulfate is high in concentration and the shark chondroitin sulfate which is produced during ion exchange can be accurately controlled, and the sodium content in the product is low; with dehydration of ultrafiltration, not only the concentration can be realized, but also the small molecular impurities can be removed to improve the purity of the shark chondroitin sulfate, at the same time, to improve the content of calcium. The method also can save the using amount of ethanol and reduce the production cost.

This invention claims a use of Capsicum and Oleoresin capsicum (OC) as a chemical shark repellent. Alkyl chain , antioxidant phenolic group, and pungency properties of capsaicin contained in OC can exert a hostile reaction on lipit membrane of gills and on nonmedullated fibre nerves of body surface of sharks, herein is provided different ways to deter sharks maintaining a high concentration of OC or Capsicum close and safe to the swimmer and scuba diver, permitting it a maximum deterrent force against sharks, It is also suitable as a coating by using paint for rescue operations devices such as the Johnson shark screen and the infant flotation device. Also this invention is proposed a use of a device for delivering a rapid squirt or atomized blast of OC to repel sharks.

A shark deterrent device is disclosed. The device comprises at least two hollow cylindrical shafts, a tip, a twist-release mechanism, and at least one self-lock mechanism. The tip may be replaceable. The shark deterrent device is a retractable unit that is easy for a diver to carry and stow, and yet can be extended in order to deter a shark. The device is unlocked from its retracted position by twisting a collar, thereby unlocking the concentric shafts and allowing the unit to be fully extendable by hand. Once the unit is fully extended, a self-lock mechanism lock the unit to prevent it from retracting during use. The unit has a handle formed at one end of the outermost cylindrical shaft and a tip at the opposing end of the innermost cylindrical shaft. The tip may be replaceable and removed, and other useful tips may be attached.

The invention relates to a design method for a uniform gradual change type high-reality shark-imitated groove microstructure on middle-size and large-size rotor blades and belongs to the field of engineering bionics techniques. The design method has the benefits that (1) the design method sufficiently considers the important fact that the middle-size and large-size rotor blades take a wing chord as a Reynolds number of a characteristic length to be changed in a radial direction of the blades; compared with an existing design which partially considers or completely ignores the fact foundation and carries out non-uniform gradual change, the design with equal width of the groove, no differentiation and uniformity is very scientific and reasonable; (2) compared with an existing non-uniform gradual change, simplified low-reality shark-imitated anti-drag and noise-reducing microstructure design, the design method for the uniform gradual change type high-reality shark-imitated groove microstructure can guarantee the more efficient actual utilization effect and each part in a virtual partition of the rotor blade can be close to or have a maximized simulated biological function.
