On June 19, 2014, the US Patent & Trademark Office published patent applications from Apple related to advancing Apple cameras for iDevices and Macs along with another original Touch ID patent that Apple acquired from Authentec. Apple's camera related patent is about advancing the actuator of an autofocus feature. While it's mildly interesting, it's the use of the term "artificial muscle" that makes it sound so incredibly futuristic, but really isn't. Apple notes that the term simply relates to electro-active polymer actuators which have been around for some time. Apple's use of it in a camera module isnt' new either as noted here and here. When this technology is applied to an artificial robotic hand, for instance, it could be understood why they use the term artificial muscle as seen here. And finally, a second patent of mild interest published today relates to one that Apple acquired from Authentec that presents the invention behind Touch ID authentication that focused on the biometrics being imlplemented into a smartphone Home Button.
