Patently Apple has dug up a patent application filed back in Q4 2009.
The device could monitor an environment by receiving a signal from an accelerometer, camera, microphone, magnetic sensor, thermometer, hygrometer (e.g., a humidity sensor), physiological sensor, any other suitable sensor or circuitry, or any combination thereof.
The new Nano could make a Garmin ForeRunner
Finally, Patently Apple notes:
[The] patent states that their invention will also apply to the iPhone, iPod Touch (PDA), iPad (tablet) and other devices which includes a laptop, gaming device and even medical equipment.
Is Apple just dreaming or will we actually see these features in the new Nano or any other iOS device? They could also just be patent trolling.
