Abstract: A data system adapted to accept certain first data associated with a game situation and to forecast future plays in athletic contests. In one embodiment, the data system comprises: a data base containing said first data and further containing second data representing a plurality of probable future plays; a data analyzer adapted to recognize said certain first data and to retrieve said corresponding second data; and a user interface, adapted to accept said certain first data and to display said retrieved second data.
Abstract: A jacket having a large storage compartment located in the upper central region of the rear of the jacket. In one embodiment of the invention, jacket 2 comprises a torso portion 8 having a large storage compartment 36 located in the upper central region of the back or rear side of torso portion 8 and having a flap 38 which can be moved from a "closed" position in which the contents of storage compartment 36 are covered and/or protected, to an "open" position in which items can be placed into or removed from storage compartment 36.
Abstract: An electromagnetically actuate machine balancer including a plurality of peripherally placed magnetic circuits and a power driver which selectively interrupts the magnetic flux through the circuits, thereby moving unbalanced rotors in a desired manner to compensate for machine unbalance.
