Abstract: An electronic system for adjusting a load bearing surface (12) such as a chair or bed to provide a desired level of comfort comprises an array of pressure sensors (14) located within the load bearing surface. The pressure sensors (14) generate data indicating the actual distribution of pressure exerted by a user on the load bearing surface. An electronic processor (40) processes the data generated by the array of pressure sensors (14). The processor (40) compares the fraction of total load exerted on each of a plurality of regions of the load bearing surface (12) with a desired range for each region. If the fraction of total load for any region is not within the desired range, a servo-mechanism (28) is activated to change the shape of the load bearing surface (12) so that the fraction of total load on each region is within the desired range, so as to provide a desired level of comfort to the user.

Abstract: A computer aided design method and system for displaying and manipulating an image of all or part of a human body is disclosed. To display an image in accordance with the invention an electronic memory stores data representing in an anthropometrically accurate manner each of a plurality of segments of a human body as a polyhedron having vertices whose coordinates are measured with respect to a joint center point. This data is then used by a graphical display device to display an anthropometrically correct image of one or more segments of a body, each displayed segment being displayed as a polyhedron. By applying rotational, translational or scaling transformations to the coordinates describing the vertices of the polyhedrons, it is possible to manipulate the corresponding graphical image of particular body segments.
