Abstract
Abstract A light transmitting rod for carrying a flash of light from a flash source to a point adjacent a translucent scale onto which the flash is projected. The rod is rotated relative to the scale. One or more flashes may be generated during one revolution of the rod relative to the scale with such flashes representing the time relation between electrical signals which in turn may represent the boundaries or limits of a measured parameter.
