Designers of air conditioning and refrigeration equipment have fresh guidelines for noise limits. The Air-Conditioning and Refrigeration Institute (ARI), based in Arlington, VA, publishes the new performance standard, ARI Standard 260-2001. Its title is "Sound Rating of Ducted Air Moving and Conditioning Equipment." That standard, along with 20 others, is available for free download on ARI's website, www.ari.org. Standard 260-2001 establishes a method of rating sound in indoor portions of ducted air moving and conditioning equipment. It provides definitions and requirements for acquiring mapped sound data. Sound power level calculations and ratings also are included, as are minimum data needs for published sound ratings and conformance conditions. ARI standards set rating criteria and procedures for measuring and certifying product performance. The ratings help buyers choose the proper equipment for specific applications.
Are they robots or androids? We're not exactly sure. Each talking, gesturing Geminoid looks exactly like a real individual, starting with their creator, professor Hiroshi Ishiguro of Osaka University in Japan.
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.
