He's chillin' with Jam Master B from anywhere in his house, thanks to a Palm Pilot equipped with a radio frequency transmitter that allows him to operate his PC-based MP3 player remotely from up to 100 ft away. An RF receiver connected to the PC acquires Steve's selections from a database of 4,700 works. To keep sound quality high, Steve encoded the music with a high bit rate and connected the sound card to his stereo amplifier via a digital link.

At the Design News webinar on June 27, learn all about aluminum extrusion: designing the right shape so it costs the least, is simplest to manufacture, and best fits the application's structural requirements.
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 radio show will show what’s possible with smart machines, and what tradeoffs need to be made to implement such a solution.
