Latest Patents

One of McNamara's latest patents is focused on edge smoothness with low-resolution projected images for use in solid imaging. This invention involves a solid imaging apparatus and method that employs sub-pixel shifting in multiple exposures of a digitally light projected image. The goal is to improve resolution while preserving image features in three-dimensional objects. This method also smooths out rough or uneven edges that may occur when using digital light projectors limited by pixel count. Algorithms are utilized to select pixels for illumination within the boundaries of each projected image.

Another significant patent is a method for making foam-in-place cushions with selective distribution of foam. This innovative approach allows for the controlled dispensing of a foam-forming composition between two plastic film portions. The foam dispenser can move transversely while dispensing foam, and a dispersion device applies pressure to predetermined areas of the film. This results in a foam cushion that can expand to fill void spaces in shipping cartons or molds, creating a desired shape.
