Abstract: By forming a plurality of separate, spaced, expansion zones in preselected areas of a foamed plastic product having a desired size and shape, a new foam plastic product is achieved which is capable of being expanded or extended in at least one direction during its use in order to accommodate dimensional changes or requirements. By forming the expansion zones in a precisely desired pattern which extends over a substantial portion of the foam plastic product, the resulting product is capable of being expanded, extended, or adjusted in at least one of its dimensions. In this way, the resulting product is quickly and easily expanded or extended in one direction to fit any desired application surface with ease and simplicity.

Abstract: By providing a unique product enhancing step which enables any desired section, portion, or element of a product being produced to be treated in a manner to provide desired enhanced physical, structural, and/or aesthetics characteristics, a new, fully integrated enhanced foam manufacturing system is attained which is capable of producing virtually any desired foam product, with each product incorporating any desired area or zone being formed with a particular physical, structural, and/or aesthetic property, characteristic, or enhancement. In addition, in accordance with the teaching of the present invention, any desired cross-sectional shape or configuration is capable of being manufactured in fully automated, high volume, rapid production conditions, with virtual ease and simplicity, with a specific physical, structural, or aesthetic property incorporated therein.

Abstract: A method and system for independent control of multiple windows in a graphics display system. Intensity data for a first plurality of pixels is specified for an underlying image within a first window. A first window identifier is associated with each of the first plurality of pixels. Next, intensity data for a second plurality of pixels is specified for an overlying image within a second window. A second window identifier is associated with each of the second plurality of pixels. The intensity data and window identifiers for the overlying and underlying images are then stored in separate locations within a frame buffer. Finally, an overall image is displayed, wherein the overall image contains the underlying image and the overlying image superimposed over at least a portion of the underlying image. The intensity data and the window identifiers are utilized to display the overall image.
