Abstract: Embodiments of motion control apparatus and systems to provide improved special effects for filmmaking are disclosed. In one embodiment, a motion control system comprises a modular track assembly comprising a plurality of connectable segments. The track assembly is configured to direct a movable trolley assembly that employs a platform to mount filmmaking equipment. The trolley assembly includes a drive assembly that responds to remotely generated control signals to move the trolley assembly along the track assembly.

Abstract: An automatic video display testing and adjusting system mounted to a CRT video display of a monitor or a TV set is made up a transparent mask, a main circuit board, a computer system which is connected to the main circuit board by a cable, a plurality of adjustable detecting sensor mounting members each having a detecting sensor engaged therewith. The detecting sensors are electrically connected to the main circuit board by wires so that the detected results are able to be fed back to the computer system for analysis and comparison by way of a main computer program. The main circuit board uses interfaces to permit the computer system to communicate with and have control over a tested monitor whereby the main computer program can perform all analytic comparison with set standards and make adjustment automatically on functional discrepancies of the display of a monitor or a TV set.
