A method and system are disclosed for predicting connections in a computer network. A mask absorber layer anisotropically etched with minimal etch bias at a relatively fast etch rate, is combined with a thin ruthenium layer, to produce a mask obviating the need for a conventional buffer or cap layer. A color burst determination circuit receives count values to determine presenceabsence of a color burst signal superimposed on the video signal. The friction elements have an upper portion oriented towards the waist opening and a lower portion oriented towards the leg opening.
