If you need to turn that ringer off in a movie theater or meeting, but find that the ol' vibrate mode just isn't doing it for you anymore (or if you need a surefire way to wake yourself up in the AM), Moto has the answer: shock mode. The company has filed for a patent on what it calls "a system that allows a cell phone to set off electrodes on a stimulator pad, alerting users of incoming calls." Moto also notes that the system can be used for "therapeutic stimulation," and that customized patterns -- think of them as the shock equivalent of ringtones -- can be downloaded to enhance the experience. We assume it'll only be a matter of time before someone figures out how to use this as a weapon (or at least a 21st century alternative to the joy buzzer) as well. And if you thought you had trouble getting through security with your camera phone, just give it a try with one of these babies.
