3. Heartbeat sensor for iPhone

Nestled among the wonderful moments of genius from Apple is this rather Orwellian little gem:

The patent suggests that future iPhones could play host to a Biometric Sensor, which would measure the users heartbeat and allow him/her access to the device if recognized. We're not entirely sure whether this level of security is entirely necessary, but then again, if you're concerned about your plans for world domination leaking out then this could be the thing for you.
