Abstract: The current invention provides an enclosure that can be placed over a patient in order to contain bodily fluids. The device includes a clear plastic sheet that fits snugly over a frame. The sides of the device contain access ports for physicians or their instruments to enter the patient’s area. These ports may be holes or hanging strips of sheet that overlap so that they form a sufficient seal while also allowing easy access to the patient when pushed aside. The bottoms of the sheet may contain weights to hold the sheet down. There is the possibility of including filters or positive/negative air flow ports. The entire device may be disposable. The frame may be solid, or the frame may pop open like an enclosure or umbrella. The device may also have straps that can be tightened underneath the bed or stretcher to secure the entire device in place.

Abstract: A multistage data routing system for routing a plurality of data streams comprises a cube comprising a plurality of stages sequentially numbered n-1 through 0 and an extra stage n situated to proceed n-1 of the cube. Stages n through 0 comprise a plurality of data switching boxes. Each box includes a first input port, a second input port, a first output port, a second output port, and apparatus for selectively coupling the first input port to at least one of the output ports and the second input port to at least one of the output ports. Extra stage n and stage 0 include apparatus for selectively bypassing stage n or stage 0 or neither stage n nor stage 0. The system further comprises a plurality of links, each coupling a selected ouput port of a selected stage to a selected input port of the next adjacent downstream stage.
