According to an Apple patent application published by the United States Patent & Trademark Office and detailed by PatentlyApple, Apple is working to implement audio transducers in combination with multiple speakers to enable surround sound configurations on MacBook-like devices. Apple’s focus of the patent appears to be improving audio in mobile devices as speakers decrease in size to accommodate smaller and thinner form factors.
As detailed in the image to the right, one embodiment of the invention shows the use of several speakers and an audio transducer integrated into the bezel and enclosure of a MacBook. These configurations would allow, for example, the speakers embedded next to the display to handle high range frequencies, while the lower speakers would handle mid-range and the audio transducer the low-range. Additional speaker enclosures could be added to enable 3.1 or 4.1 surround sound configurations. Apple also stated the audio transducer could provide both low and mid-range frequencies, “essentially performing as a “subtweeter” for frequency ranges from 20-500 Hz and 500-1500 Hz.

Update: Nokia has responded to reports that Apple is offering to license its nano-SIM patents royalty-free by claiming Apple does not have patents “essential to its nano-SIM proposal” (via ITworld):
“We are not aware of any Apple Intellectual Property which it considers essential to its nano-SIM proposal. In light of this, Apple’s proposal for royalty-free licensing seems no more than an attempt to devalue the intellectual property of others.”
In recent weeks, reports popped up that suggest Apple is attempting to push a new standard for miniaturized SIM cards. In May 2011, Reuters reported Apple “submitted a new requirement to (European telecoms standards body) ETSI for a smaller SIM form factor.” More recent reports from the Financial Times confirmed other companies, including Motorola and Nokia, were attempting to push their own “nano-SIM” design. At the time, FT said Apple had support from “most of the European operators.” Ahead of the Smart Card Platform Plenary meeting with the European Telecommunications Standards Institute this Thursday and Friday, Foss Patents reports Apple is promising the ETSI it will license any Apple-owned patents related to nano-SIM free of charge to its competitors:
With the introduction of the new LTE iPad on Verizon and AT&T, many were wondering whether AT&T’s 3G network would work on a new Verizon iPad. According to a poster on the Mac Rumors forums, popping an AT&T SIM card into the Verizon iPad’s micro-SIM slot appears to work fine as long as you adjust the AT&T APN carrier settings. Of course, this does not mean you will be able to use AT&T’s LTE network on the Verizon iPad. However, if you already have an AT&T SIM for the iPhone, this is an alternative for data when LTE is not an option.
