Embodiments of the invention include a partially insulated field effect transistor and a method of fabricating the same. A vortex generator disposed at a narrow end of the chamber generates a spiral vortex that rises up the wall. In addition, prioritization of multicast transmission of digital content to multiple clients accessing a shared interactive environment can be realized. In one embodiment, the debugger further includes a target resident debug server that is scheduled by the kernel processing unit to execute debugging commands issued by the host debug. Pixel data x that corresponds to the target position in the image signal Vb is supplied to an addition portion. The sensing circuit determines the current or the temperature of the sensing element during an active period of the clock signal.
