Using a solid immersion lens having a spherical lens surface with a radius of curvature RL from a material having a refractive index nL, an image of a sample is observed. The control circuit is composed of MOS elements. Within the first time interval, a second source task may be executed to broadcast a second destination task, within the second sequential time interval, the second destination task may be communicated over the channel to a second destination, and within the third sequential time interval, the second destination task may be consumed.
