An electrical failure in a relay has caused Maytag Corp. to recall 1.6 million refrigerators. The faulty relay, which turns on the refrigerator’s compressor, can cause overheating and is considered a potential fire hazard. A Maytag web site says that it has received 41 reports of “refrigerator relay ignition,” including 16 reports of property damage. Affected brands include Maytag, Jenn-Air, Amana, Admiral, Crosley, Magic Chef, and Performa by Maytag. To learn about affected models and serial numbers see the company’s repair web site.
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.
