An extruded-aluminum four-cylinder prototype IC (internal combustion) engine, demonstrated late last year, took less than seven months to deve-lop. Power Beat Intl. Ltd. claims the technology provides the following advantages for engine design and manufacture:
- High efficiency
- Low cost
- Light weight
- Less engine noise
- Fewer parts than conventional designs
The engine, code named ALU-X(TM), uses an extruded-aluminum cylinder block, crank case, head, and sump "plate," all held together with tie rods. Also, piston valves replace poppetvalves and allow for a side valve arrangement that increases theefficiency of the engine, reducesnoise, extends overall life and reduces engine height compared to overhead valve engines.

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.
