A method of operating gaming device that enables players to accumulate awards until there are no more awards or until one or more termination variables reaches a predetermined limit is provided. Adjustable transistor body bias circuitry is provided on the integrated circuit that provides body bias voltages to the body terminals to minimize power consumption. A spinneret introduces a stream of liquid biopolymer into the laminar flow of coagulation fluid so that the stream is surrounded and swept downstream by the coagulation fluid as it coagulates into a biopolymer fiber. The luffspar is rotationally supported in an upper journal wherein the upper journal, upper end of the mast, and upper ends of the pair of lateral struts are all engaged in a common fixture held in place by the mast and the lateral struts. The shielding element has a protruding shield convex exposed through the opening.
