- ELECTRONICALLY INCLINED TO STAY ON THE LEVEL
-
- Spirit levels, which since the 17nth century have trustily
- ensured that surfaces are level, may soon be pushed out by
- a microprocessor-contolled rival that can set a true
- horizontal, a vertical or any angle in between, to one-tenth
- of a degree.
-
- The heart of the SMARTLEVEL, produced by Wedge Innovations
- in San Jose, California, is a device called a liquid-filled
- inclinometer. A sealed capsule contains two parallel conducting
- discs with a space, partially filled with iquid between them.
-
- ... Any pair of parallel conductors acts as a store of electrical
- charge. Its ability to store charge, its capacitance, is influenced
- by what is between the conductors.

- MY OPINION
-
- Since this is a liquid device, you"re not going to get
- millisecond sensing time, which would be nice if your
- going to right yourself like a falling cat.
-
- Also, it has to be reset if it gets jarred, a real
- problem probably.
