If all those warnings of violent and graphic images before any show that's part of the Discovery Channel's "Shark Week" make you shudder, fear no more: We've got a list of non-lethal gadgets that will make you feel a bit safer while swimming at the beach, watching shark-filled programs, or even to keep by your bed while you have nightmares about sharks.

Take a look at these gadgets after the jump.

The Shark Shield: Invented by the South African Government through the Natal Shark Board, the Shark Shield can be used when you're participating in any ocean activities, including surfing, bodyboarding, snorkelling, and so on. It works by sending out electronic waves that vibrate and cause spasms in the shark's snout--causing it not to return. Get a Shark Shield for around $700.

The Shark Shocking Wet Suit : The Shark Shocker uses the sensitive receptors in a shark's snout against it. Made of metal and neoprene, the wetsuit has thin piezoelectric ceramic fibers woven into its fabric. During normal swimming, the suit continually generates several volts, which flow through the water between the electrodes to create a deterrent field. If the diver sees an shark and swims fast to get away--and who wouldn't--the suit generates much higher voltages and stronger fields.

Robotic Shark: If watching the Discovery Channel this week is not enough to satisfy your love of underwater creatures, then the Remote Controlled Robotic Bull Shark from Hammacher Schlemmer may help. Have fun scaring people at the beach with this state-of-the-art robot that swims smoothly, just like a real shark. It can move up, down, left, right, and even backwards for up to 9 feet under water and can also also swim to a maximum length of 40 feet. The remote control is also submersible, allowing you to be undetected as you swim near your shark. The Robotic Bull Shark goes for $99.95.

Shark Fin Power System: Sharks may be dangerous for surfers and swimmers alike, but their framework has inspired scientists to develop an underwater electricity system. This development, called the bioSTREAM Tidal Power Conversion System, copies the shape and movements of the fins of sharks and other ocean animals, but uses fins in the opposite direction to generate power. Scientists are currently working on systems for 250kW and 500kW power generation.

Shark Yourself: Do you have a little shark in you? You will after visiting the Discovery Channel Web site. You just upload a photo, scale it to size, crop it, select a set of your favorite shark teeth, and pick a background. I sharked myself; my skin doesn't blend well with the body the app gave me, but it was fun, and free.
