A new Apple patent for smartwatch designs and features is bound to fuel more speculation about an incoming "iWatch," even though such claims often amount to nothing. Still, the patent is interesting on its own merits. One version shows a receptacle band that could accept an external "iTime" module as shown above -- not unlike the iPod Nano watch craze from 2010. However, Apple's band has built-in electronics like Bluetooth transceivers, along with accelerometers and GPS modules -- sensors rumored to be built-in to Apple's upcoming wearable. According to the document, that would enable smartphone or computer notifications that you could see, hear or feel. You'd also be able to dismiss notifications or perform other actions by shaking your wrist once or several times, according to another claim.
