Dow-United Technologies Composite Products Inc. has developed a patented process for using braided composites to make jet engine thrust reversers, the devices that slow aircraft during landing. In the past, the primary section of the reversers, cascades, was made from magnesium castings or from aluminum, making the multi-part structures comparatively heavy and susceptible to fatigue or stress failure at critical points. The Dow-UT process uses braided carbon fibers and resins to create a much lighter part with substantially greater strength at the joints. In addition, the part comes off the assembly line as a single component, reducing ultimate assembly requirements, according to Lawrence Varholak, Dow-UT vice president, engineering and technology. The patent represents an enhancement of Dow-UT's Advanced Resin Transfer Molding (AdvRTM(TM)) process. FAX (203) 949-5009.
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.
