Earlier today, the U.S. Patent and Trademark Office on Tuesday has issued Apple a patent that describes how this new technology is able to monitor the aging of a device’s electronics, where it will then make a comparison of the data against a global average as well as modifying operating parameters so that performance can be maximized, in addition to helping nudge battery efficiency and user experience in the right direction throughout the entire device’s advertised lifetime. Apple’s U.S. Patent No. 8,671,170 has been described as “Modifying operating parameters of a device based on aging information”, where it depicts a system which relies on aging detection circuits in order to monitor electronic components in a portable device, where an iPhone is not exempt.
As it stands, the Raspberry Pi is more than capable of audio output using its HDMI port, but it is always nice to have additional flexibility as part of the mix, especially if you are an avid DIY enthusiast. This is one particular reason that Element 14 has decided to team up with Wolfson Audio in order to roll out an official add-on sound card for the Raspberry Pi. This new add-on sound card board will cost approximately $33 a pop, where it boasts of SPDIF in/out, 3.5mm headphone and mic jacks, RCA line out and in, and direct speaker connection pins that are on the board itself. This makes it the ideal base if you intend to work on a portable, Raspberry Pi-powered arcade emulator cabinet.
