To light the way home after a late night cramming at the library, Christina and friends designed this smart bike light. Using two microcontrollers and powered by a battery pack that mounts to the bike's down tube, the device monitors both the bicycle speed (via Hall Effect magnet) and amount of daylight (via photoconductive cell). When dwindling light is detected during operation, the unit sounds an on-tone and exposes and turns on an array of white LEDs. A four-line LCD display indicates both status and speed.

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.
