Abstract: A graphical, interactive debugger for a computer-based discrete-event simulation model of systems having parallel processes includes a run-time graphic user interface module in which predefined events of the executing simulation model are animated, and a run-time interface simulator module for controlling execution of the simulation model based on commands from the graphical user interface. The model and the animation are based on hierarchical directed process execution graphs in which a transaction represents one of several processes executing in parallel within the system modeled with the graphs. One transaction at a time is shown moving between nodes in one of the graphs. The animation follows the transaction as it moves between sub-models represented by each graph, switching to other graphs as needed. Once the transaction is blocked, the next transaction is displayed in context of the appropriate graph and followed until it is blocked. The screen on which animation is presented is divided into two areas.

Abstract: A package comprising a container having regular information on an outer surface thereof and a wrapper extending at least partially over the container surface and bearing information of which at least some is substantially identical to at least some of the regular information on the outer container surface.

Abstract: A cover sheet for medical tables, beds or gurneys comprises a sheet formed from a high tensile strength, plastic with opposed ends of the sheet folded and seamed to provide pockets. The pockets are inverted for assemblage over the ends of the medical tables, beds or gurneys. Methods of continuously fabricating such cover sheets from a roll of plastic material are also disclosed.

Abstract: An exerciser for treating wrist injuries or conditions including carpal tunnel syndrome is formed by a handle attached to a track of continuous loops. A moveable bead on the track is maneuvered from one end of the track to the other by manipulating the exerciser preferable with the patient using only her wrist. The motion required to move the bead along the track is therapeutic for those suffering from wrist disorders including carpal tunnel syndrome. Additionally, the track is formed from a flexible material allowing the track to be moved between a compressed position for storage and travel and an expanded position for use.
