The method uses the tri-state logic capabilities of microcontrollers in order to gain efficiency over traditional multiplexing.

To gain efficiency, longer sections can be chosen that appear to the eye to have uniform curvature.

With this function implemented in the name server, user applications gain efficiency in design and operation.

Larger groups have more scope to invest in technology and gain efficiencies of scale.

Then that gave way to employing contractors and squeezing them to gain efficiencies.
