International Classification:

G06F 1566

US Classification:

364518

Abstract:

A system is disclosed for subdividing parametric patches for use in a computer graphics system to develop images. The system utilizes initial data, provided as by an interactive user, to represent control points for an initial patch from which the system rapidly computes control points for subpatches using parallel processors. The disclosed system is recursive so that each level of subdivision leads to greater refinement of an initial patch. In one embodiment, the processors in the system compute multiple control points, the grouping of processors exploiting patch symmetrical properties.

Abstract:

A method for adjusting the pressure of one or more cushions in a human transport system is disclosed. The one or more cushions include a plurality of inflatable chambers and a plurality of pressure sensors associated with the cushions. The pressure sensors may be surface pressure sensors or chamber pressure sensors. A processor associated with the human transport system obtains pressure measurements from the plurality of pressure sensors. Based on the pressure measurements, the processor identifies one or more of the plurality of inflatable chambers whose pressure requirements adjustment. The processor then sends commands that cause the human transport system to adjust the pressure in the one or more inflatable chambers. Systems including cushions and processors are also disclosed.
