As mobile phones offer functions far beyond simple telephonic communications, the human machine interface becomes more important. KEYnetik Inc. developed a Motion Enabled Prototype Phone that lets owners navigate with just one hand. Users can select icons by simply tilting the device in the desired direction and pressing a button when their selection is highlighted. A pair of Analog Devices' ADXL330 iMEMS accelerometers are key components, providing six degrees of freedom and filtering out motion interference by determining where the force is coming from. Automatic screen rotation and simplified gaming control are also features of the prototype phone.
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.
