Patent attributes
The present invention relates to the reduction of tissue interface pressure. The present invention provides a method to immerse an individual to a desired depth into a support surface. The method of the present invention maintains a desired level of immersion over time independent of the motion of the individual or changes in the position of the support surface or externally applied loads to the support surface, alone or in combination. The method of the present invention is an improvement to using an individual's weight or height or other sensor to determine inputs to an algorithm for immersing the individual to a certain depth into the surface. No pressure measurements or displacement measurements are required in accordance with the present invention, and the height and weight of the individual is not required.
