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."
Now one would think if this was put in a movie prior to the filing of the patent thus placing it in the public domain. This patent should not have been issued no ?? thoughts ? anyone anyone
