The invention is a state machine having a host controller that controls a level-1 controller, wherein the level-1 controller controls the level-2 controller. The level-2 controller controls system component controllers, which in turn control system components to execute a process segment. For example, the machine includes a host controller that selects a set of states to be executed, a level-1 controller that activates the set of states in a predetermined order, wherein each state includes commands, and a level-2 controller that controls system components according to the commands. A method of executing a process includes identifying a set of states to be executed, issuing state commands that need to be issued to execute the current state in the set of states, and activating a next state only after all expected status reports have been received for the current state.

Disclosed is a stereoscopic optical inspection system. A computer uses the stereoscopic information to compute and correct for angular and distance misalignments between the unit-under-test and the inspection system. A feature of the optical system is the use of multiple high-resolution inspection cameras, in conjunction with a single stereoscopic reference camera. One example of a preferred embodiment is presented as an electro-optical inspection system for inspection and/or alignment of cathode-ray-tube displays and other video displays on a production assembly line.
