Abstract: In an optical communication network, a variable rate or non-uniform input rate signal is converted to a “pseudo” signal comprising a uniform or standard data rate for the optical communication system. At the receiver, the original non-uniform rate signal is recovered.

Abstract: A vertical jump testing device comprising a plurality of vertically arranged measuring elements each pivotally mounted on a vertically disposed mounting member and independently movable between a first and second position to measure the vertical leaping ability of an athlete as the athlete strikes and angularly displaces one or more of the plurality of vertically arranged elements from the first position to the second position and a reset mechanism to reset the angularly displaced vertically arranged elements from the second position to the first position.
