A discrete event simulation and method of model development provide affordable, accurate, pre-validated, reusable and portable models and simulations that capture the complexity, interdependencies and stochastic nature of the operations and support of weapons systems. One aspect of the semiconductor package comprises a leadframe, a semiconductor chip attached to the leadframe, electrical connectors electrically connecting the semiconductor chip to the leadframe, and a sealing material. When a full-motion animation is desired, a start pose and a target pose may be provided, and a multiple-path, multiple-iteration search through the database may be used to assemble the full-motion animation. Related Ethernet Y-switches and methods of using the Ethernet Y-cables and Y-switches are also provided. The drive assembly is operationally coupled to the base assembly for rotating the frame member with respect to the base assembly. More particularly, the present invention relates to methods and apparatus for addressing pixels in a display using one or more movable mechanical scanning mechanisms.
