The United States Patent and Trademark Office has made public several patents deposited by Apple.
- The first describes the sleep mode of our Macs, in particular the saving of the contents of the memory and instant re-awakening.
- The second concerns the management of energy in the computer.
- The third describes a system of anti-copy protection for software based on a Watermark and a unique key.
- The fourth describes the usage of capacitors to stabilise the voltage and reduce the noise of a power supply.
- The fifth describes a library system capable of storing different types of documents; a bit like that already done in iTunes which mixes music, videos and Podcasts.
- The sixth describes a system of using a magnet to fix the power cord, otherwise known as the MagSafe, that we believe is one of the most beautiful inventions of Apple.
Thus there is a bit of everything in these patents, but not much to serve as a base of speculation.
