Mechanical
The most basic form of mechanical motion detection is in the form of a switch or trigger. These motion detection devices are common in our everyday lives. The keys of a typewriter, or even the keys on the keyboards used to type this article employ a mechanical method of detecting motion. Each key is a manual switch that is either off or on. Each letter that appears is a result of motion on that corresponding key and the switch being turned on. This simple binary code concept is at the heart of the digital age, with mechanical switches being replaced by ever shrinking transistors.

Famous quotes containing the word mechanical:
“The correct rate of speed in innovating changes in long-standing social customs has not yet been determined by even the most expert of the experts. Personally I am beginning to think there is more danger in lagging than in speeding up cultural change to keep pace with mechanical change.”
—Mary Barnett Gilson (1877–?)
“Industry has operated against the artisan in favor of the idler, and also in favor of capital and against labor. Any mechanical invention whatsoever has been more harmful to humanity than a century of war.”
—Rémy De Gourmont (1858–1915)
“No sociologist ... should think himself too good, even in his old age, to make tens of thousands of quite trivial computations in his head and perhaps for months at a time. One cannot with impunity try to transfer this task entirely to mechanical assistants if one wishes to figure something, even though the final result is often small indeed.”
—Max Weber (1864–1920)
