Here's RIM's official explanation about the Blackberry Buzz I blogged about recently.
>>>Unfortunately, this "buzzing" is a characteristic that is unavoidable on any mobile phone that operates in the GSM 850/1900 MHz range (not just BlackBerry, but all other phones also).
Essentially, whenever the phone transmits or receives on the 850/1900 MHz band any nearby speakers are "excited" and there is an audible buzzing.
The only suggestion I have to reduce the annoying buzz, is to keep the BlackBerry handset away from any speakers (or any wires leading to speakers). So when you set it down on your desk, try putting it as far away from the speaker as needed (or you can turn off the speakers when they aren't needed).
This is a trait of the GSM design and not specific to BlackBerry.<<

Robots that walk have come a long way from simple barebones walking machines or pairs of legs without an upper body and head. Much of the research these days focuses on making more humanoid robots. But they are not all created equal.
The IEEE Computer Society has named the top 10 trends for 2014. You can expect the convergence of cloud computing and mobile devices, advances in health care data and devices, as well as privacy issues in social media to make the headlines. And 3D printing came out of nowhere to make a big splash.
For industrial control applications, or even a simple assembly line, that machine can go almost 24/7 without a break. But what happens when the task is a little more complex? That’s where the “smart” machine would come in. The smart machine is one that has some simple (or complex in some cases) processing capability to be able to adapt to changing conditions. Such machines are suited for a host of applications, including automotive, aerospace, defense, medical, computers and electronics, telecommunications, consumer goods, and so on. This discussion will examine what’s possible with smart machines, and what tradeoffs need to be made to implement such a solution.
