On March 28, 2013, the US Patent & Trademark Office published a patent application from Apple that reveals another waterproofing idea for small portable devices. Apple has shown to have been working on a waterproof, or at the very least, a water resistant solution for over a year now. We covered this subject in a well-documented report last March. Today a new patent application illustrates that they're also working on a different angle to creating water resistant devices using a multi-layered ceramic enclosure mixed with Alumina to provide the enclosure with a good RF transmission capability. Our report also touches on another interesting process that Apple is working on called a "Shot Peening, Shot Blasting Process" for creating part flatness.
