General purpose methods for the fabrication of integrated circuits from flexible membranes formed of very thin low stress dielectric materials, such as silicon dioxide or silicon nitride, and semiconductor layers. Signals are sent from a computer system to appropriate sensors based on a player’s or game object’s position to activate connected light-emitting fibers that are blended with grass on a playing field. The headpiece includes a support portion mounted therein. Convolution can take place either before or after rectification. The ink comprises a carbon black, an organic pigment, a dispersant incorporated in an aqueous medium and a saccharide. for a second stage time of 2 to 10 minutes at a second stage pressure of 167 to 262 psig.
