@dplmark: MEMS are used in some hearing aids. There are some companies working on MEMS speakers, but the challenge is that the MEMS membrane is very small (<1mm) - it's hard to drive a lot of air (i.e. sound volume) with such a small membrane. One approach is to create an array of MEMS speakers for close listening range apps.
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.
