Abstract: A system for monitoring the percentage of stretch of a stretch wrap film in a stretch wrapping machine includes a first sensor associated with the stretch wrap roll and configured to generate a first signal as the film travels from the roll to the pre-stretch roller assembly, and a second sensor associated with the load and configured to generate a second signal as the film is wrapped around the load. A processor is operable to: a) calculate a pre-stretch length of the film based on the first signal during a time interval; b) calculate a stretched length of the film as the film is wrapped around the load on the rotating platform during the time interval; and c) calculate a percentage stretch of the film based on the pre-stretch length and said stretched length.

Abstract: A DVD Player based Tic-Tac-Toe game played utilizing the capabilities of a DVD player via either a stand alone DVD Player or a software-based DVD Player on a computer. The game is limited to a person challenging a DVD Player using fixed automatic opposing player logic. By matching up symmetrical patterns of the resulting tokens, after each opposing token position is selected, the number of unique DVD menus needed for a base version of the game (which never allows the person playing the game to win) can be reduced to just 30 DVD Menus. This matching is arrived at by animating in 3-D space the transitions of the Tic-Tac-Toe game board via flipping and/or rotating between game board states. It then allows alternate paths of game play to be added to the fixed logic that can allow a person to win. It also allows custom content to be arrived at during game play.
