Abstract: A storage medium encoded is provided for use in synchronization of a server database, which includes a plurality of tables and which is accessible on a server computer system, and a client database, which is accessible on a client computer system and which includes a subset of the tables in the server database, the storage medium comprising a first distribution point table in the server database which has the property that modification of such first distribution point table may influence distribution of information from the server database to the client database during a synchronization of the server database and the client database; a first distribution table which corresponds to the first distribution point table which is separate from the server database application tables and which includes identification information that identifies occurrences of information within the server database that may require distribution to the client database during a synchronization of the server database and the client datab

Abstract: A shock-displacing inflatable bag for use in balance games, recreation or exercise comprises a bag constructed of material that does not stretch or otherwise absorb shock. The bag is formed from a single sheet of material which is first joined at a set of opposite edges using a lap seam. The lap seam allows the bag to roll from side to side without restriction. The two open ends of the bag are then joined using sandwich seams. A valve is then mounted over a hole in the bag for purposes of inflation and deflation. Radio frequency heat sealing provides a method for creating strong, permanent seams which can withstand forces imparted to the bag. Denser vinyl coated, woven fabrics provide the best resistance to shock and stretch.
