A thin film transistor including a substrate, a semiconductor layer, a patterned doped semiconductor layer, a source and a drain, a gate insulation layer, and a gate is provided. Interleaved multimedia streams can include compressed video frames for display in a video window, accompanying compressed audio frames and annotation frames. The rotary shutters can be collectively rotated between an open position and an closed position. Using the advantages of that solution the circuit of the invention is manufactured with standard CMOS technology and only very few discrete external components. Another simulator is operated by a student. In a post-crimp position, proximal and distal ends of an inner surface of the tubing contact an insulation jacket of the cable conductor and a sharp edge of the at least one splice opening penetrates the insulation jacket and contacts a conductive core of the cable conductor to provide electrical communication between the crimp connector and the cable connector.
