On April 18, 2013, the US Patent & Trademark Office published a series of patents relating to next generation audio and data connectors. Apple has already begun to move to more modern efficient connectors like "Lightning" for the iPhone 5. Apple's patent delves into future versions of connectors that could eventually replace the traditional iDevice audio connector that employs traditionally rounded TRS connector jacks with something flatter and possibly shallower as noted in our cover graphic. Apple's proposed data connectors are being designed to address USB 4.0, DVI, Display Port and HDMI and work with everything from the Mac to an iPhone and right through to possible future devices such as a gaming system and a holographic projector, states Apple. Our report also touches on two Apple patents covering new spring loaded connectors that won't overheat.
