The Tongue Twisting Tooth Microphone
dylanduck writes "New Scientist has found a patent for a microphone that clips on your tooth, meaning you can stay in radio contact even the noisiest situations - like warzones. You use your tongue to flip it on and off. Here is the patent itself. The same article mentions a blimp that launches like a rocket."
Actually, stormtrooper comms were just in the helmets; though the devices were controlled with the tongue, they don't have anything inside the mouth.
